Description

Method for sending uplink information, terminal equipment and access network equipment

Technical Field

The present application relates to the field of communications, and in particular, to a method for sending uplink information, a method for receiving uplink information, a terminal device, and an access network device.

Background

Mobile communication technology has profoundly changed people's lives, but the pursuit of higher performance mobile communication technology has never stopped. In order to cope with explosive mobile data traffic increase, massive mobile communication device connection, and various new services and application scenarios which are continuously emerging, the fifth generation (5G) mobile communication system is in operation.

For 5G high-reliability low-latency communication (URLLC) services, there are two basic requirements: firstly, the higher delay requirement brought by service emergency, for example, the delay of the uplink and downlink user plane specified at present cannot exceed 0.5 ms; secondly, the requirement on reliability is high, for example, the error rate within 1ms cannot exceed 0.001%. The generation of data packets of URLLC traffic is bursty and random, and may not generate data packets for a long time or may generate multiple data packets for a short time. The data packets of URLLC traffic are in most cases small packets, e.g. 50 bytes. The characteristics of the data packets of URLLC traffic can affect the manner in which resources are allocated to the communication system.

In the prior art, when a plurality of Uplink channels include a Physical Uplink Control Channel (PUCCH) and a Physical Uplink Shared Channel (PUSCH), a priority relationship between the PUCCH and the PUSCH follows a principle that a priority of a Channel carrying Uplink control information is higher than a priority of a Channel not carrying Uplink control information. Since the uplink control information is control information related to downlink service transmission, and the priority of a channel carrying the uplink control information is higher than the priority of a channel not carrying the uplink control information, it is realized that the priority of the downlink service transmission is higher than the priority of the uplink service transmission.

However, for 5G URLLC traffic, the uplink and downlink user plane delay cannot exceed 0.5ms and the bit error rate cannot exceed 0.001%. If the priority of the channel which always carries the uplink control information is higher than the priority of the channel which does not carry the uplink control information by adopting the prior art, the time delay and the reliability requirement of the 5G URLLC uplink service can not be met.

Disclosure of Invention

The embodiment of the application provides a method for sending uplink information and a method for receiving uplink information, which are used for solving the problem that when a plurality of uplink channels are transmitted simultaneously, terminal equipment determines the sending power of each channel according to the priority of each channel and then sends the channel according to the sending power of each channel so as to meet the requirements on time delay and reliability in a 5G scene, or the problem that when UE cannot send a first channel and a second channel simultaneously, a channel with higher priority is sent so as to meet the requirements on time delay and reliability in the 5G scene is solved.

The technical scheme of the application is mainly applied to two scenes, one of the scenes is that the sum of initial powers of at least two channels which bear uplink information by the terminal equipment in a first time period is greater than a power threshold of the terminal equipment, the terminal equipment needs to reduce the sending power of the channels and determine the sending power of each channel according to the priority of each channel and the sequence from low to high of the priority, so that the sum of the reduced sending powers of each channel is not greater than the power threshold of the terminal equipment, and the uplink information borne by each channel is sent on the channel with the sending power greater than 0.

The second scenario is that the terminal device does not allow the first channel and the second channel to be sent in the first time period, and then the specific reason that the terminal device does not allow the first channel and the second channel to be sent in the first time period is that the terminal device's own capability does not allow the uplink information of the bearer to be sent on the first channel and the second channel at the same time, or the terminal device receives configuration information of the base station, where the configuration information indicates that the terminal device cannot send the uplink information of the bearer on the first channel and the second channel at the same time, and the uplink information of the bearer needs to be sent on a channel with a high priority according to priorities of the two channels.

A first aspect of the present embodiment provides a method for sending uplink information, which may include: the terminal equipment determines the sending power of a first channel and a second channel according to the priority of the first channel and the second channel, wherein the first channel and the second channel are channels in at least two channels which bear uplink information in a first time period, and the sum of the initial power of the at least two channels is greater than the power threshold of the terminal equipment; that is, since the sum of the initial powers of at least two channels carrying uplink information sent by the terminal device in the first time period is greater than the power threshold of the terminal device, the terminal device needs to know the priorities of the at least two channels, so as to reduce the initial powers of the channels with low priorities and obtain the sending powers of the channels with low priorities, and the sending power of the channel with high priorities is the initial power of the channel with low priorities; in another case, when the sum of the initial transmission powers of the channels with high priority is already greater than the power threshold of the terminal device, the channels with low priority have no chance to transmit, that is, the transmission power of the channel with priority can be considered as 0, and the initial power of the channel with high priority needs to be reduced to obtain the transmission power of the channel with high priority. The terminal device transmits at least one of the first channel and the second channel according to the transmission power of the first channel and the second channel. That is, the terminal device sends the uplink information carried on the first channel and the second channel according to the sending power of the first channel and the second channel.

In the embodiment of the present application, a first channel and a second channel are used for illustration, and in practical application, there may be a situation that more than 2 channels exist, and a specific implementation manner thereof is similar to that of the 2 channels, and details are not described here. The scenario applied in this embodiment is that in the first time period, the sum of the initial powers of at least two channels carrying uplink information is greater than the power threshold of the terminal device, and then the terminal device cannot transmit the at least two channels in the first time period, and needs to determine the transmission powers of the first channel and the second channel according to the priorities of the at least two channels, where the transmission power of the channel with the low priority is reduced first, and the transmission power of the channel with the high priority may not be reduced, or may be reduced later, depending on the situation. Therefore, the first channel and the second channel can be sent according to the sending power of the first channel and the second channel, namely, the uplink information carried on the first channel and the second channel is sent according to the sending power of the first channel and the second channel, and the uplink information of the channel with high priority can be timely sent. The problem that when a plurality of uplink channels are transmitted simultaneously, the terminal equipment determines the sending power of each channel according to the priority of each channel can be solved, and the requirements of the URLLC on time delay and reliability in a 5G scene are met.

In combination with the first aspect of the embodiment of the present application, the following possible implementation manners may also be included, but are not limited to, as follows:

(1) the priority of the second channel is higher than that of the first channel, wherein the uplink information carried on the first channel comprises uplink data, and the uplink information carried on the second channel comprises NACK feedback information corresponding to the downlink data received by the terminal equipment. For example, the first channel is a PUSCH, the second channel is a PUCCH, the PUSCH carries uplink data, the PUCCH carries NACK feedback information corresponding to downlink data received by the terminal device, then the priority of the PUCCH is higher than that of the PUSCH, and due to a higher delay requirement caused by URLLC service urgency, if the control information transmitted in the second channel includes NACK feedback information corresponding to downlink URLLC data, the base station retransmits an information packet of previous downlink URLLC data to the UE by receiving the NACK feedback information transmitted by the UE, so that the downlink URLLC service can meet a specified reliability requirement within a specified delay requirement. Optionally, the first channel is a channel used by the UE to transmit scheduling-free uplink data. Optionally, the first channel is an uplink shared channel, and the second channel is an uplink control channel.

(2) The priority of the first channel is higher than that of the second channel, wherein the uplink information carried on the first channel includes uplink data, and the uplink information carried on the second channel includes ACK feedback information corresponding to the downlink data received by the terminal device. For example, the first channel is a PUSCH, the second channel is a PUCCH, the PUSCH carries uplink data, the PUCCH carries ACK feedback information corresponding to downlink data received by the terminal device, and therefore the priority of the PUSCH is higher than that of the PUCCH, because the ACK feedback information indicates that the terminal device receives downlink data sent by the access network device correctly, it is not very important whether the ACK feedback information is fed back to the access network device in time, and therefore the uplink data carried on the PUSCH should be sent in time, so that transmission of the uplink information of the UE meets the requirements of low latency and high reliability of the downlink URLLC service. Optionally, the first channel is a channel used by the UE to transmit scheduling-free uplink data. Optionally, the first channel is an uplink shared channel, and the second channel is an uplink control channel.

(3) If the uplink information carried on the first channel comprises NACK feedback information corresponding to the downlink data received by the terminal equipment, and the uplink information carried on the second channel comprises uplink data, the priority of the first channel is higher than that of the second channel; if the uplink information carried on the first channel includes ACK feedback information corresponding to the downlink data received by the terminal device, and the uplink information carried on the second channel includes uplink data, the priority of the second channel is higher than that of the first channel.

It is mainly intended to express the priority of a channel including NACK feedback information > the priority of a channel including uplink data > the priority of a channel including ACK feedback information, where the channel including uplink data may be a PUSCH and the channel including NACK feedback information or ACK feedback information is a PUCCH. Optionally, the second channel is a channel used by the UE to transmit scheduling-free uplink data. Optionally, the second channel is an uplink shared channel, and the first channel is an uplink control channel.

(4) If the uplink information borne on the first channel comprises first type channel state feedback information corresponding to downlink data received by the terminal equipment, and the uplink information borne on the second channel comprises uplink data, the priority of the first channel is higher than that of the second channel, and the first type channel state feedback information is channel state information obtained by the terminal equipment according to a reference signal corresponding to the received first downlink data; if the uplink information carried on the first channel includes second-type channel state feedback information corresponding to downlink data received by the terminal device, and the uplink information carried on the second channel includes uplink data, the priority of the second channel is higher than that of the first channel, and the second-type channel state feedback information is periodic channel state feedback information or semi-continuous channel state feedback information, or channel state information sent by the terminal device according to received channel state information feedback parameters.

And if the first channel carries the first type channel state feedback information, the second channel carries uplink data. Due to the higher delay requirement caused by the urgent URLLC service, if the control information transmitted in the first channel comprises the first type channel state feedback information, the base station adjusts the scheduling information of the information packet of the downlink URLLC data before the UE repeatedly or resends the scheduling information by receiving the first type channel state feedback information sent by the UE, so that the downlink URLLC service can meet the specified reliability requirement within the specified delay requirement. Therefore, if the first channel carries the first type channel state feedback information, the priority of the first channel may be higher than that of the second channel, so that the transmission of the uplink information of the UE meets the requirements of low latency and high reliability of the downlink URLLC service.

And if the first channel carries the second type channel state feedback information, the second channel carries uplink data. And if the control information transmitted in the first channel comprises second-type channel state feedback information, the base station adjusts the scheduling information of downlink data transmitted by the UE in the subsequent scheduling by receiving the second-type channel state feedback information transmitted by the UE. Therefore, if the first channel carries the second type channel state feedback information, the influence on the reliability requirement within the delay requirement of the downlink URLLC data is not large, and therefore, the priority of the first channel may be higher than that of the second channel, so that the transmission of the uplink information of the UE meets the low-delay high-reliability requirement of the uplink URLLC service.

Therefore, when the uplink control information sent by the UE is the second type of channel state feedback information, the priority of the channel carrying the uplink control information is lower than the priority of the channel carrying the uplink data, and when the uplink control information sent by the UE is the first type of channel state feedback information, the priority of the channel carrying the uplink control information is higher than the priority of the channel carrying the uplink data. Therefore, the method is beneficial to simultaneously considering the service requirements of low time delay and high reliability of the downlink URLLC and the uplink URLLC. Optionally, the first channel is a channel used by the UE to transmit scheduling-free uplink data. Optionally, the first channel is an uplink shared channel, and the second channel is an uplink control channel.

(5) The priority of the first channel is higher than that of the second channel, wherein the uplink information carried on the first channel comprises uplink data, and the uplink information carried on the second channel comprises HARQ-ACK feedback information and/or channel state information corresponding to the downlink data received by the terminal equipment. For example, the first channel is a PUSCH, the second channel is a PUCCH, and here, no matter how the access network device has transmitted downlink data to the terminal device, the PUCCH is only one piece of feedback information for the downlink data received by the terminal device, or is one piece of feedback information for the state of the downlink channel, and uplink data carried in the PUSCH is not yet transmitted, so the priority of the PUSCH may be considered to be higher than that of the PUCCH. Optionally, the first channel is a channel used by the UE to transmit scheduling-free uplink data. Optionally, the first channel is an uplink shared channel, and the second channel is an uplink control channel.

(6) The priority of the first channel is equal to the priority of the second channel, wherein the uplink information carried on the first channel comprises HARQ-ACK feedback information corresponding to downlink data received by the terminal equipment, the uplink information carried on the second channel comprises first type channel state feedback information, and the first type channel state feedback information is channel state information obtained by the terminal equipment according to a reference signal corresponding to the received first downlink data. Illustratively, the UE does not need to demodulate and decode the first downlink data to obtain the first type of channel state information. Before demodulating and decoding the first downlink data and obtaining the HARQ-ACK information of the data, the UE can quickly obtain the first type channel state information through the reference signal corresponding to the data. The base station can rapidly adjust the scheduling parameter of the downlink data transmission after the data according to the first type channel state information by acquiring the first type channel state information sent by the UE, so as to meet the requirements of low time delay and high reliability of the downlink URLLC data transmission. The transmission quality is greatly improved by timely feedback of the first type channel state information and adjustment which possibly occurs according to the feedback, and the service quality of the downlink URLLC service can be improved. Similarly, the demodulation and decoding of the first downlink data or other downlink data received and the HARQ-ACK information obtained by the UE also play an important role in the decision of the base station on the scheduling parameters for scheduling downlink data transmission and downlink data packets for transmission for the downlink data after the current time. In this case, the priority of the first channel may be set to be equal to the priority of the second channel, which is beneficial to meet the service requirements of low latency and high reliability of URLLC data.

(7) The priority of the second channel is higher than that of the first channel, wherein the deadline of the uplink information carried on the first channel is later than the deadline of the uplink information carried on the second channel, or the remaining number of repeated transmissions of the data corresponding to the uplink information carried on the first channel is greater than the number of repeated transmissions of the data corresponding to the uplink information carried on the second channel. It should be noted that, both downlink transmission and uplink transmission may require multiple transmissions to meet the high reliability requirement of the URLLC service of 5G. But URLLC may simultaneously require that the uplink and downlink user plane delay cannot exceed 0.5 ms. Therefore, if the delay upper limit of uplink or downlink is exceeded by excessive repeated transmission, it is not meaningful for URLLC service. Accordingly, if the traffic corresponding to the first of the two uplink channels is the remaining time of the deadline time for the delay requirement, the second channel is only the first transmission of the multiple transmissions. In this case, the first channel may be sent preferentially, that is, the corresponding uplink information is sent on the first channel, so as to meet the service requirement of the service corresponding to the first channel. The UE still has an opportunity to retransmit the second channel before the expiration time of the second channel. Therefore, it is also possible that the UE determines the priority of the first channel and the second channel based on the remaining time of the deadline for the arrival delay (latency) requirement.

(8) The priority of the second channel is higher than that of the first channel, wherein the uplink information carried on the first channel comprises HARQ-ACK feedback information and/or channel state information corresponding to downlink data received by the terminal equipment, and the uplink information carried on the second channel comprises uplink data; and the deadline of the uplink information carried on the first channel is equal to the deadline of the uplink information carried on the second channel, or the remaining number of repeated transmissions of the data corresponding to the uplink information carried on the first channel is equal to the number of repeated transmissions of the data corresponding to the uplink information carried on the second channel.

Optionally, the UE determines to send the first type channel state feedback information according to the received first type downlink data. Optionally, the first type of downlink data is data of a first service type. For example, if the deadline of the uplink information carried on the PUCCH is equal to the deadline of the uplink information carried on the PUSCH, or the remaining number of repeated transmissions of the uplink information carried on the PUCCH is equal to the number of repeated transmissions of the uplink information carried on the PUSCH, if the PUCCH is a channel for carrying uplink control information and the PUSCH is a channel for carrying uplink data, the PUCCH carries feedback information of downlink data transmitted by the terminal device to the access network device, and the uplink data carried on the PUSCH is not transmitted, so the priority of the PUSCH can be considered to be higher than the priority of the PUCCH.

(9) The priority of the second channel is higher than that of the first channel, wherein the uplink information carried on the first channel comprises uplink data, and the uplink information carried on the second channel comprises NACK (negative acknowledgement) feedback information corresponding to the downlink data received by the terminal equipment; and the deadline of the uplink information carried on the first channel is equal to the deadline of the uplink information carried on the second channel, or the remaining number of repeated transmissions of the data corresponding to the uplink information carried on the first channel is equal to the number of repeated transmissions of the data corresponding to the uplink information carried on the second channel.

Optionally, the UE determines to send the first type channel state feedback information according to the received first type downlink data. Optionally, the first type of downlink data is data of a first service type. For example, if the deadline of the uplink information carried on the PUSCH is equal to the deadline of the uplink information carried on the PUCCH, or the remaining number of repeated transmissions of the uplink information carried on the PUCCH is equal to the number of repeated transmissions of the uplink information carried on the PUSCH, and if the PUSCH is a channel for carrying uplink data, the PUCCH is a channel for carrying uplink control information, and the uplink control information includes NACK feedback information corresponding to the downlink data received by the terminal device, the priority of the PUCCH may be considered to be higher than the priority of the PUSCH, because the NACK feedback information indicates that the terminal device receives a downlink data reception error sent by the access network device, the access network device needs to be notified, and the access network device may send the downlink data to the terminal device in time.

(10) The priority of the second channel is higher than that of the first channel, wherein the uplink information carried on the first channel comprises ACK feedback information corresponding to the downlink data received by the terminal equipment, and the uplink information carried on the second channel comprises uplink data; and the deadline of the uplink information carried on the first channel is equal to the deadline of the uplink information carried on the second channel, or the remaining number of repeated transmissions of the data corresponding to the uplink information carried on the first channel is equal to the number of repeated transmissions of the data corresponding to the uplink information carried on the second channel. Optionally, the UE determines to send the first type channel state feedback information according to the received first type downlink data. Optionally, the first type of downlink data is data of a first service type. For example, if the deadline of the uplink information carried on the PUCCH is equal to the deadline of the uplink information carried on the PUSCH, or the remaining number of repeated transmissions of the uplink information carried on the PUCCH is equal to the number of repeated transmissions of the uplink information carried on the PUSCH, if the PUCCH is a channel for carrying uplink control information including ACK feedback information corresponding to downlink data received by the terminal device, and the PUSCH is a channel for carrying uplink data, then the priority of the PUSCH may be considered higher than the priority of the PUCCH, because the ACK feedback information indicates that the terminal device receives correct downlink data transmitted by the access network device, and the uplink data carried on the PUSCH is not transmitted, so the uplink data carried on the PUSCH may be transmitted first.

(11) If the uplink information carried on the first channel comprises NACK feedback information corresponding to the downlink data received by the terminal equipment, and the uplink information carried on the second channel comprises uplink data, the priority of the first channel is higher than that of the second channel; if the uplink information carried on the first channel includes ACK feedback information corresponding to the downlink data received by the terminal device, and the uplink information carried on the second channel includes uplink data, the priority of the second channel is higher than that of the first channel. And the deadline of the uplink information carried on the first channel is equal to the deadline of the uplink information carried on the second channel, or the remaining number of repeated transmissions of the data corresponding to the uplink information carried on the first channel is equal to the number of repeated transmissions of the data corresponding to the uplink information carried on the second channel.

(12) If the uplink information borne on the first channel comprises first type channel state feedback information corresponding to downlink data received by the terminal equipment, and the uplink information borne on the second channel comprises uplink data, the priority of the first channel is higher than that of the second channel, and the first type channel state feedback information is channel state information obtained by the terminal equipment according to a reference signal corresponding to the received first downlink data; if the uplink information carried on the first channel includes second-type channel state feedback information corresponding to downlink data received by the terminal device, and the uplink information carried on the second channel includes uplink data, the priority of the second channel is higher than that of the first channel, and the second-type channel state feedback information is periodic channel state feedback information or semi-continuous channel state feedback information, or channel state information sent by the terminal device according to received channel state information feedback parameters.

And the deadline of the uplink information carried on the first channel is equal to the deadline of the uplink information carried on the second channel, or the remaining number of repeated transmissions of the data corresponding to the uplink information carried on the first channel is equal to the number of repeated transmissions of the data corresponding to the uplink information carried on the second channel.

(11) The schemes of (4) and (12) mainly refer to the cases of the priorities of the first channel and the second channel under the condition that the deadline of the uplink information carried on the first channel is equal to the deadline of the uplink information carried on the second channel, or the remaining number of repeated transmissions of the data corresponding to the uplink information carried on the first channel is equal to the number of repeated transmissions of the data corresponding to the uplink information carried on the second channel, which is not described herein again.

Further, if the deadline of the uplink information carried on the first channel is not equal to the deadline of the uplink information carried on the second channel, or the remaining number of repeated transmissions of the data corresponding to the uplink information carried on the first channel is not equal to the number of repeated transmissions of the data corresponding to the uplink information carried on the second channel, the priorities of the first channel and the second channel may be determined according to (7); if the deadline of the uplink information carried on the first channel is equal to the deadline of the uplink information carried on the second channel, or the remaining number of repeated transmissions of the data corresponding to the uplink information carried on the first channel is equal to the number of repeated transmissions of the data corresponding to the uplink information carried on the second channel, the priorities of the first channel and the second channel may be determined according to any one of (8) to (12).

(13) The priority of the second channel is higher than that of the first channel, wherein the uplink information carried on the first channel comprises a first uplink data packet, the uplink information carried on the second channel comprises a second uplink data packet, and the arrival time of the second uplink data packet is later than that of the first uplink data packet. Optionally, the UE determines to send the first type channel state feedback information according to the received first type downlink data. Optionally, the first type of downlink data is data of a first service type. For example, the first channel and the second channel are a first PUSCH and a second PUSCH, the first PUSCH is used for carrying a first uplink data packet, the second PUSCH is used for carrying a second uplink data packet, and the time that the second uplink data packet arrives at the terminal device is later than the first uplink data packet.

(14) The priority of the second channel is higher than that of the first channel, wherein the first channel is a channel scheduled by first signaling, the second channel is a channel scheduled by second signaling, and the time of receiving the first signaling by the terminal equipment is earlier than that of receiving the second signaling by the terminal equipment. Optionally, the UE determines to send the first type channel state feedback information according to the received first type downlink data. Optionally, the first type of downlink data is data of a first service type. For example, the first PUSCH is a channel scheduled by the first signaling, the second PUSCH is a channel scheduled by the second signaling, and the time when the terminal device receives the first signaling is earlier than the time when the second signaling is received, it is proved that the access network device knows that the first signaling is sent to the terminal device before, the first signaling indicates that the terminal device is scheduled in the first time period, but the access network device sends the second signaling later, and the second signaling indicates that the terminal device is also scheduled in the first time period, so that the access network device knows that the first signaling is already sent in the first time period and sends the second signaling again, which indicates that the second signaling is urgent, and the priority of the corresponding channel is higher than the priority of the channel corresponding to the first signaling.

(15) The priority of the second channel is higher than that of the first channel, wherein the first channel is a channel free from signaling scheduling, and the second channel is a channel scheduled by signaling. And if the scheduling type of the first channel is the signaling-free scheduling and the scheduling type of the second channel is the signaling scheduling, the priority of the second channel is higher than that of the first channel. After the base station sends the first physical downlink control information, the UE needs to send the second data of the UL grant free at the same time as the first channel according to the arrival condition of the uplink data of the UE, which indicates that the second data is very urgent. Therefore, in this case, the priority of the second channel is higher than that of the first channel, which can embody the low-latency requirement principle of the UE for the uplink URLLC data transmission.

Optionally, the UE determines to send the first type channel state feedback information according to the received first type downlink data. Optionally, the first type of downlink data is data of a first service type. For example, the first PUSCH is a channel for signaling-free scheduling, the second PUSCH is a channel for signaling scheduling, the signaling scheduling is decided by the access network device, the signaling-free scheduling is decided by the terminal device, and the priority of the decision by the access network device is considered to be higher than that of the decision by the terminal device, so the priority of the second PUSCH is higher than that of the first PUSCH here.

In the embodiment of the application, several conditions for determining the priorities of the first channel and the second channel are provided, so that the priorities of the first channel and the second channel can be more effectively determined, various realizable modes are provided for the embodiment of the application, and the selectivity of the scheme is increased.

In a possible implementation manner of (14) above in this embodiment of the application, the first signaling and the second signaling each include information indicating a time position of the first time period.

With reference to the first aspect of the embodiment of the present application, in the first aspect of the present application, the implementation manner may further include that a sum of transmission powers of the first channel, the second channel, and other channels of the at least two channels is less than or equal to the power threshold.

A second aspect of the present application provides a method for receiving uplink information, which may include: the access network equipment receives at least one channel of a first channel and a second channel sent by terminal equipment according to the sending power of the first channel and the second channel, wherein the first channel and the second channel are channels of at least two channels which bear uplink information in a first time period, and the sum of the initial power of the at least two channels is greater than the power threshold of the terminal equipment. It can be understood that the access network device receives the uplink information carried on the first channel and the second channel sent by the terminal device according to the sending power of the first channel and the second channel. That is, since the sum of the initial powers of at least two channels carrying uplink information sent by the terminal device in the first time period is greater than the power threshold of the terminal device, the terminal device needs to know the priorities of the at least two channels, so as to reduce the initial powers of the channels with low priorities and obtain the sending powers of the channels with low priorities, and the sending power of the channel with high priorities is the initial power of the channel with low priorities; in another case, when the sum of the initial transmission powers of the channels with high priority is already greater than the power threshold of the terminal device, the channels with low priority have no chance to transmit, that is, the transmission power of the channel with priority can be considered as 0, and the initial power of the channel with high priority needs to be reduced to obtain the transmission power of the channel with high priority.

With reference to the second aspect of the embodiment of the present application, in a first possible implementation manner of the second aspect of the embodiment of the present application, the method may further include: the access network equipment determines the transmission power of the first channel and the second channel according to the priority of the first channel and the second channel.

In combination with the second aspect of the embodiment of the present application, reference may be made to the possible implementation manners including but not limited to (1) - (15) provided in the first aspect of the embodiment of the present application, and details are not repeated here.

A third aspect of the present embodiment provides a method for sending uplink information, which may include: the method comprises the steps that terminal equipment determines a channel with higher priority in a first channel and a second channel, wherein the first channel and the second channel are channels in at least two channels which bear uplink information in a first time period, and the terminal equipment cannot simultaneously send the first channel and the second channel in the first time period; the terminal device transmits the channel with higher priority. It should be noted that, the UE determines that it is not allowed to simultaneously send the uplink information of the bearer on the first channel and the second channel, where a specific case may be that the UE receives the configuration information sent by the base station, and the configuration information indicates that the UE may not simultaneously send the uplink information of the bearer on the first channel and the second channel, or that the configuration case of the UE itself does not support simultaneous sending of the uplink information of the bearer on the first channel and the second channel.

In the embodiment of the application, the terminal device determines a channel with a higher priority in a first channel and a second channel, where the first channel and the second channel are channels of at least two channels that carry uplink information in a first time period, and the UE cannot simultaneously send the first channel and the second channel in the first time period. The terminal equipment transmits the channel with higher priority. The method can solve the problem that when the UE does not support two channels to simultaneously send the carried uplink information, the channel with higher priority is selected to send the carried uplink information, thereby meeting the requirements of the URLLC on time delay and reliability.

In combination with the third aspect of the embodiment of the present application, the following possible implementation manners may also be included, but are not limited to, as follows:

(1) the priority of the second channel is higher than that of the first channel, wherein the uplink information carried on the first channel comprises uplink data, and the uplink information carried on the second channel comprises NACK feedback information corresponding to the downlink data received by the terminal equipment.

(2) The priority of the first channel is higher than that of the second channel, wherein the uplink information carried on the first channel includes uplink data, and the uplink information carried on the second channel includes ACK feedback information corresponding to the downlink data received by the terminal device.

(5) The priority of the first channel is higher than that of the second channel, the uplink information borne on the first channel comprises uplink data, and the uplink information borne on the second channel comprises HARQ-ACK feedback information and/or channel state information corresponding to the downlink data received by the terminal equipment; wherein the first channel is a schedule-free channel; and/or the transmitting the higher priority channel of the first channel and the second channel in the first time period comprises: and sending the first channel in the first time period, wherein the uplink information sent on the first channel does not include the HARQ-ACK feedback information and/or channel state information corresponding to the downlink data received by the terminal equipment.

For example, the first channel is a PUSCH, the PUSCH is a scheduling-free channel, the second channel is a PUCCH, and regardless of this, the access network device has already transmitted downlink data to the terminal device, and the PUCCH is only one feedback on the downlink data received by the terminal device, or one feedback on the state of the downlink channel, and uplink data carried in the PUSCH has not yet been transmitted, so it can be considered that the priority of the PUSCH is higher than that of the PUCCH. And/or the first channel is a PUSCH, the second channel is a PUCCH, and regardless of how, the access network device has sent downlink data to the terminal device, and the PUCCH is only one feedback of the downlink data received by the terminal device or one feedback of the state of the downlink channel, uplink data carried in the PUSCH is not sent, and uplink information carried on the PUSCH does not include uplink control information in the PUCCH, so that the priority of the PUSCH can be considered to be higher than the priority of the PUCCH.

(6) The priority of the first channel is equal to the priority of the second channel, wherein the uplink information carried on the first channel comprises HARQ-ACK feedback information corresponding to downlink data received by the terminal equipment, the uplink information carried on the second channel comprises first type channel state feedback information, and the first type channel state feedback information is channel state information obtained by the terminal equipment according to a reference signal corresponding to the received first downlink data.

(7) The priority of the second channel is higher than that of the first channel, wherein the deadline of the uplink information carried on the first channel is later than the deadline of the uplink information carried on the second channel, or the remaining number of repeated transmissions of the data corresponding to the uplink information carried on the first channel is greater than the number of repeated transmissions of the data corresponding to the uplink information carried on the second channel.

Both downlink transmission and uplink transmission may require multiple transmissions to meet the high reliability requirement of the 5G URLLC service. But URLLC may simultaneously require that the uplink and downlink user plane delay cannot exceed 0.5 ms. Therefore, if the delay upper limit of uplink or downlink is exceeded by excessive repeated transmission, it is not meaningful for URLLC service. Accordingly, if the traffic corresponding to the first of the two uplink channels is the remaining time of the deadline time for the delay requirement, the second channel is only the first transmission of the multiple transmissions. In this case, the first channel may be sent preferentially, that is, the corresponding uplink information is sent on the first channel, so as to meet the service requirement of the service corresponding to the first channel. The UE still has an opportunity to retransmit the second channel before the expiration time of the second channel. Therefore, it is also possible that the UE determines the priority of the first channel and the second channel based on the remaining time of the deadline for the arrival delay (latency) requirement.

For example, the first channel may be a PUSCH, and the second channel may be a PUCCH, or the first channel may be a PUCCH and the second channel is a PUSCH, or the first channel is a first PUSCH and the second channel is a second PUSCH, which is not limited specifically. If the deadline of the uplink information carried on the first channel is later than the deadline of the uplink information carried on the second channel, or the remaining number of repeated transmissions of the uplink information carried on the first channel is greater than the number of repeated transmissions of the uplink information carried on the second channel, it can be understood that the deadline of the uplink information carried on the first channel is greater than the deadline of the uplink information carried on the second channel, and therefore the uplink information carried on the second channel is relatively more urgent, and therefore, the priority of the second channel can be considered to be higher than the priority of the first channel.

(10) The priority of the second channel is higher than that of the first channel, wherein the uplink information carried on the first channel comprises ACK feedback information corresponding to the downlink data received by the terminal equipment, and the uplink information carried on the second channel comprises uplink data; and the deadline of the uplink information carried on the first channel is equal to the deadline of the uplink information carried on the second channel, or the remaining number of repeated transmissions of the data corresponding to the uplink information carried on the first channel is equal to the number of repeated transmissions of the data corresponding to the uplink information carried on the second channel.

(13) The priority of the second channel is higher than that of the first channel, wherein the uplink information carried on the first channel comprises a first uplink data packet, the uplink information carried on the second channel comprises a second uplink data packet, and the arrival time of the second uplink data packet is later than that of the first uplink data packet.

(14) The priority of the second channel is higher than that of the first channel, wherein the first channel is a channel scheduled by first signaling, the second channel is a channel scheduled by second signaling, and the time of receiving the first signaling by the terminal equipment is earlier than that of receiving the second signaling by the terminal equipment.

(15) The priority of the second channel is higher than that of the first channel, wherein the first channel is a channel free from signaling scheduling, and the second channel is a channel scheduled by signaling.

It should be noted that, the UE determines that it is not allowed to simultaneously send the uplink information of the bearer on the first channel and the second channel, where a specific case may be that the UE receives the configuration information sent by the base station, and the configuration information indicates that the UE may not simultaneously send the uplink information of the bearer on the first channel and the second channel, or that the configuration case of the UE itself does not support simultaneous sending of the uplink information of the bearer on the first channel and the second channel.

In this embodiment of the present application, an access network device receives a channel with a higher priority from among a first channel and a second channel sent by a terminal device, where the first channel and the second channel are channels of at least two channels that carry uplink information in a first time period, and the terminal device cannot send the first channel and the second channel at the same time in the first time period. The method can solve the problem that when the UE does not support two channels to simultaneously send the carried uplink information, the channel with higher priority is selected to send the carried uplink information, thereby meeting the requirements of the URLLC on time delay and reliability.

Detailed Description

The embodiment of the application provides a method for sending uplink information, which is used for solving the problem that when a plurality of uplink channels are transmitted simultaneously, terminal equipment determines the sending power of each channel according to the priority of each channel and then sends the channel according to the sending power of each channel so as to meet the requirements on time delay and reliability in a 5G scene, or when UE (user equipment) cannot send a first channel and a second channel simultaneously, the channel with higher priority is sent so as to meet the requirements on time delay and reliability in the 5G scene.

Brief introduction to 5G technology:

the International Telecommunications Union (ITU) defines three broad classes of application scenarios for 5G and future mobile communication systems: enhanced mobile broadband (eMBB), high-reliability and low-latency communications (URLLC), and massive machine type communications (mtc).

Typical eMBB services are: the services include ultra high definition video, Augmented Reality (AR), Virtual Reality (VR), and the like, and these services are mainly characterized by large transmission data volume and high transmission rate. Typical URLLC services are: the main characteristics of the applications of wireless control in industrial manufacturing or production processes, motion control of unmanned automobiles and unmanned airplanes, and haptic interaction such as remote repair and remote operation are that ultra-high reliability, low time delay, less transmission data volume and burstiness are required. Typical mtc services are: the intelligent power distribution automation system has the main characteristics of huge quantity of networking equipment, small transmission data volume and insensitivity of data to transmission delay, and the mMTC terminals need to meet the requirements of low cost and very long standby time.

For the URLLC service of 5G, there are two basic requirements: firstly, higher time delay requirement brought by service emergency; secondly, the requirement on reliability is higher. The generation of data packets of URLLC traffic is bursty and random, and may not generate data packets for a long time or may generate multiple data packets for a short time. The data packets of URLLC traffic are in most cases small packets, e.g. 50 bytes. The characteristics of the data packets of URLLC traffic can affect the manner in which resources are allocated to the communication system. Resources herein include, but are not limited to: time domain symbols, frequency domain resources, time frequency resources, codeword resources, beam resources, and the like. For example, multiple subcarrier spacings are supported in Next Radio (NR) systems to accommodate different traffic demands. In the frequency domain, the supported subcarrier spacing type is fsc — f0 × 2 m. Where f0 is 15kHz, and m is an integer. In the time domain, as shown in fig. 1, an exemplary diagram of the relationship between subframes, slots and mini-slots at different frequencies is shown.

Subframe (Subframe): the length of 1 subframe is 1ms, and 14 Orthogonal Frequency Division Multiplexing (OFDM) symbols at 15Khz subcarrier spacing. Within 1 subframe, the symbol boundaries for various numerologies for subcarrier spacing of 15KHz and above 15KHz are aligned.

A Slot (Slot) is a possible time length of a scheduling unit. The 1 Slot includes y OFDM symbols currently used. An integer number of slots are included in the 1 subframe. In the case where the subcarrier spacing is 60KHz or less, y is 7; in the case where the subcarrier spacing is 60KHz or more, y is 14.

The Mini-slot (Mini-slot) is the minimum length of time for a scheduling unit. The 1 Mini-slot may comprise less OFDM symbols than the currently used y symbols.

Considering the low latency service requirement of URLLC traffic, mini-slots (mini-slots) or larger sub-carrier spaced slots are typically used as the time granularity of the scheduling unit.

Uplink data transmission of 5G URLLC:

in a 4G Long Term Evolution (LTE) wireless communication system, if a UE has no uplink data to transmit, a base station (Evolved NodeB, eNodeB) does not need to allocate uplink resources for the UE, otherwise, resources are wasted. Therefore, the UE needs to tell the eNodeB whether there is uplink data to transmit itself, so that the eNodeB decides whether to allocate uplink resources to the UE. For this purpose, LTE provides a Scheduling Request (SR) mechanism. The UE tells the eNodeB whether uplink resources are needed for uplink data transmission through the SR. And after receiving the SR, the eNodeB allocates uplink resources to the UE for the UE to send uplink data. A similar approach may also be supported in 5G URLLC. And the UE sends a scheduling request to the base station, and the base station indicates resources for sending uplink data to the UE through scheduling indication information. In order to meet the flexibility requirement of the base station on the scheduling resources of the UE, the time for the base station to send the uplink data scheduling information to the UE and the time for the resources corresponding to the uplink data information may be variable in a dynamic and/or semi-static manner. For example, the time for transmitting uplink data corresponding to the uplink data scheduling information transmitted by the base station in the time slot n is the time slot n + k, where the value of k is notified to the UE by the base station in a dynamic and/or semi-static manner.

On the other hand, the manner in which the UE transmits the scheduling request to the base station and the base station indicates the resource for transmitting the uplink data to the UE through the scheduling indication information may have an influence on the transmission time of the uplink data of the UE. For example, when the UE has an uplink data transmission requirement, the UE needs to wait for SR transmission, and the base station indicates uplink data scheduling information to actually transmit uplink data, and time spent in these processes affects uplink data transmission delay of the UE. Uplink grant free (UL grant free) or non-scheduled uplink data transmission can effectively meet the requirements of URLLC technology on reliability and low latency of data transmission. By using the UL grant free technology, the uplink data transmission of the terminal device does not depend on the dynamic notification of the network device. The network device configures the resource for sending the uplink data of the UL grant free to the terminal device by sending the pre-configuration information to the terminal device, and when the terminal device has the uplink data transmission requirement, the network device sends the uplink data on the resource pre-configured for the network device without sending a scheduling request to the base station and waiting for the scheduling indication information of the base station.

In the uplink data transmission in the 5G URLLC, at least one of the above SR-based scheduling and UL grant free may be used.

Downlink data transmission of 5G URLLC:

the downlink data transmission is based on base station scheduling. The specific scheduling procedure is that the base station sends a Control Channel, such as a Physical Downlink Control Channel (PDCCH) or an Enhanced Physical Downlink Control Channel (EPDCCH), where the Control Channel may carry scheduling information of a Downlink data Channel, such as a Physical Downlink Shared Channel (PDSCH), or an Uplink data Channel, such as a Physical Uplink Shared Channel (PUSCH), and the scheduling information includes Control information of the Downlink data Channel or the Uplink data Channel, such as resource allocation information and Control information of adjusting a coding scheme. The UE detects the control channel and performs reception of a downlink data channel or transmission of an uplink data channel according to scheduling information carried in the detected control channel.

In the case of supporting Hybrid Automatic Repeat Request (HARQ) transmission, after receiving downlink data, if the reception is correct, the UE sends Acknowledgement (ACK) feedback information on a Physical Uplink Control Channel (PUCCH), and if the reception is incorrect, sends non-acknowledgement (NACK) feedback information on the PUCCH. The ACK feedback information and the NACK feedback information are collectively referred to as HARQ-ACK feedback information. Alternatively, the HARQ-ACK feedback information may further include ACK feedback information, NACK feedback information, and Discontinuous Transmission (DTX) feedback information. DTX feedback information, if UE does not receive downlink data in the downlink data channel, UE correspondingly sends DTX feedback information to the downlink data channel. After receiving the NACK feedback information of the downlink data, the base station may perform retransmission scheduling on the downlink data. After receiving the ACK feedback information for the downlink data, the base station may suspend scheduling downlink resources for the UE if there is no more downlink data to be transmitted.

The PUCCH resource for transmitting and receiving the HARQ-ACK information corresponding to the downlink data by the UE may be a resource configured by the base station for the UE. For example, the configuration resource includes at least one of time, frequency, reference signal sequence, and the like occupied by the PUCCH. In addition, the configuration resource may further include an alternative value of a time interval between the PUCCH and the PDSCH, or an alternative value of a time interval between the PUCCH and the PDCCH. When the base station schedules downlink data for the UE, as shown in fig. 2, a schematic diagram of a time position of a PUCCH used for feeding back HARQ-ACK of corresponding downlink data may be indicated in a control channel. For example, the time position is indicated as one of the alternative values of the time interval between the PUCCH and the PDSCH, or the time position is indicated as one of the alternative values of the time interval between the PUCCH and the PDCCH, or the time position is directly indicated as a value of the time interval between the PUCCH and the PDCCH.

Uplink power control in a wireless system is very important, and through the uplink power control, a terminal device can ensure the quality of transmitted uplink data, reduce interference to the system and other users as much as possible, and prolong the service time of a battery of the terminal device. The base station can make the uplink transmission adapt to different wireless transmission environments through power control, including path loss, shadow, fast fading, interference of other terminal devices in a cell and among cells, and the like. The base station has a corresponding control mechanism for the power of each uplink channel sent by the UE, and the UE determines the initial power of each channel to be sent according to the corresponding power control mechanism of each uplink channel. When a plurality of uplink channels need to be transmitted simultaneously, it may be determined that the sum of the initial powers of the plurality of uplink channels is greater than the maximum power allowed for UE transmission according to the power control result. In this case, the UE determines the transmission power of each channel for the transmission power of each channel in accordance with the priorities of the plurality of uplink channels, and transmits an uplink channel having a transmission power other than 0 among the plurality of uplink channels. The transmission power is the transmission power of each of these uplink channels.

In the prior art, when a plurality of uplink channels include a PUCCH and a PUSCH, the priority relationship between the PUCCH and the PUSCH is as follows: the priority of PUCCH is higher than that of PUSCH; or, the PUCCH and the PUSCH are not distinguished, and the channel containing the HARQ-ACK has higher priority than the channel not containing the HARQ-ACK. However, for 5G URLLC traffic, the uplink and downlink user plane delay cannot exceed 0.5ms and the bit error rate cannot exceed 0.001%. If the priority of the channel which always carries the uplink control information is higher than the priority of the channel which does not carry the uplink control information by adopting the prior art, the time delay and the reliability requirement of the 5G URLLC uplink service can not be met.

The system architecture or scenario in which the present application is primarily applied is shown in fig. 3, and includes an access network device 101 and terminal devices 102, 103. Both the access network equipment 101 and the terminal equipment 102,103 may operate in a base station and terminal equipment in a licensed or unlicensed frequency band. Whether the licensed frequency band or the unlicensed frequency band is the licensed frequency band or the unlicensed frequency band, the unlicensed frequency band and the unlicensed frequency band may include one or more carriers, and the licensed frequency band and the unlicensed frequency band may perform carrier aggregation, and the one or more carriers included in the licensed frequency band may include one or more carriers included in the unlicensed frequency band. In this application, a cell mentioned may be a cell corresponding to a base station, and the cell may belong to a macro base station or a base station corresponding to a small cell (small cell), where the small cell may include: urban cells (Metro cells), Micro cells (Micro cells), Pico cells (Pico cells), Femto cells (Femto cells), and the like, and the small cells have the characteristics of small coverage area and low transmission power, and are suitable for providing high-rate data transmission services. The carrier wave in the wireless communication system can simultaneously work with a plurality of cells at the same frequency, and under some special scenes, the concept of the carrier wave in the wireless communication system is equivalent to that of the cells. For example, in a carrier aggregation scenario, when a secondary carrier is configured for a terminal device, a carrier index of the secondary carrier and a Cell identity (Cell identity) of a secondary Cell operating on the secondary carrier may be simultaneously carried, and in this case, it may be considered that the carrier is equivalent to a Cell concept, for example, it is equivalent to that the terminal device accesses one carrier and one Cell.

The Access network device may be an LTE system, an NR system, or an evolved node B (eNB or e-NodeB) macro base station, a micro base station (also referred to as a "small base station"), a pico base station, an Access Point (AP), a Transmission Point (TP), or a NodeB (new generation base station) in an authorized assisted Access long-term evolution (LAA-LTE) system. The Terminal device may be referred to as a User Equipment (UE), a Mobile Station (MS), a Mobile Terminal (Mobile Terminal), an intelligent Terminal, and the like, and may communicate with one or more core networks through a Radio Access Network (RAN). For example, the terminal equipment may be a mobile phone (or so-called "cellular" phone), a computer with a mobile terminal, etc., and the terminal equipment may also be a portable, pocket, hand-held, computer-included or vehicle-mounted mobile device and terminal equipment in future NR networks, which exchange voice or data with a radio access network. Description of terminal device: in this application, the terminal device may further include a Relay, and the terminal device and the base station that can perform data communication may be regarded as the terminal device.

The technical scheme of the application is mainly applied to two scenes, wherein one scene is a scene that the sum of the initial powers of at least two channels of the terminal equipment carrying the uplink information in the first time period is greater than the power threshold of the terminal equipment, so that the terminal equipment can determine the sending powers of the first channel and the second channel according to the priorities of the first channel and the second channel, wherein the first channel and the second channel are the channels of the at least two channels carrying the uplink information in the first time period; the terminal device transmits at least one of the first channel and the second channel according to the transmission power of the first channel and the second channel. That is, the terminal device needs to sequentially reduce the transmission power of the channels and determine the transmission power of each channel according to the priority of each channel and the sequence from low to high, so that the sum of the reduced transmission powers of each channel is not greater than the power threshold of the terminal device, and transmit the uplink information carried by each channel on which the transmission power is greater than 0.

The second scenario is that the terminal device cannot send the first channel and the second channel in the first time period, and then the terminal device determines a channel with higher priority in the first channel and the second channel, wherein the first channel and the second channel are channels of at least two channels for bearing uplink information in the first time period; the terminal equipment transmits the channel with higher priority. The specific reason why the terminal device cannot send the first channel and the second channel in the first time period is that the capability of the terminal device does not support sending the loaded uplink information on the first channel and the second channel at the same time, or the terminal device receives configuration information of the base station, wherein the configuration information indicates that the terminal device cannot send the loaded uplink information on the first channel and the second channel at the same time, and the loaded uplink information needs to be sent on a channel with a high priority according to the priorities of the two channels.

In the above two scenarios, the channels to be transmitted by the terminal device in the first time period include at least two channels, where the first channel and the second channel are channels of the at least two channels. The first channel and the second channel both carry uplink information. As shown in fig. 3(a), a schematic diagram of uplink information carried by each of a first channel and a second channel to be sent in a first time period is shown. The access network device sends downlink data, such as a PDSCH, to the terminal device at time T1, where HARQ-ACK feedback information corresponding to the PDSCH is fed back on the PUCCH in the first time period. Meanwhile, the access network device sends scheduling indication information of uplink data to the terminal device at time T2, and instructs the terminal device to send the uplink data on the PUSCH channel in the first time period. Alternatively, as shown in fig. 3(b), the uplink information carried by each of the first channel and the second channel is to be sent in the first time period. The access network device sends downlink data, such as a PDSCH, to the terminal device at time T1, where HARQ-ACK feedback information corresponding to the PDSCH is fed back on the PUCCH in the first time period. The terminal equipment needs to send uplink data on a scheduling-free PUSCH in a first time period. In this way, in the first time period, the channels to be transmitted by the terminal device include PUCCH and PUSCH channels.

For another example, as shown in fig. 3(c), it is another schematic diagram of uplink information carried by each of the first channel and the second channel to be sent in the first time period. The access network equipment sends scheduling indication information of uplink data to the terminal equipment at time T1, and the terminal equipment is indicated to send first uplink data in a PUSCH channel of a first time period. And in consideration of the low-delay performance requirement of the URLLC uplink service transmission, the access network device sends the scheduling indication information of the uplink data to the terminal device again at time T2, and instructs the terminal device to send the second uplink data on another PUSCH channel in the first time period. In this way, in the first time period, the channels to be transmitted by the terminal device include two PUSCH channels.

The uplink information comprises uplink data information and/or uplink control information. The uplink control information includes HARQ-ACK, channel state information, scheduling request information, etc. The priority between the uplink channels is determined according to the types of the uplink information carried in the uplink channels, so that the transmission of the uplink information with higher priority can be ensured.

In this application, the first channel and the second channel are channels of at least two channels that carry uplink information in the first time period. The first channel and the second channel may each be equal or unequal in length in time. Optionally, the resources of the first channel in time and the resources of the second channel in time completely overlap. Or the resource of the first channel in time and the resource of the second channel in time partially overlap, the first time period is the overlapping part of the first channel and the second channel in time, or the first time period is the time of the first channel, or the first time period is the time of the second channel, or the first time period is the union of the first channel and the second channel in time. Fig. 3(d) is an exemplary diagram of different situations of the first channel, the second channel and the first time period.

The embodiment of the application can determine which channel to send the uplink information borne on first according to the priority of the channel, compared with the prior art, the scheme that the priority for sending the uplink control information is higher than the priority for sending the uplink data is adopted.

In the following, the technical solution of the present application may be further described in an embodiment, as shown in fig. 4, an embodiment of a method for sending uplink information provided in the embodiment of the present application is illustrated, which is described with respect to a scenario where a sum of initial powers of at least two channels, which bear uplink information in a first time period, of a terminal device is greater than a power threshold of the terminal device, and the scenario includes:

401. the terminal equipment determines the sending power of a first channel and a second channel according to the priority of the first channel and the priority of the second channel, wherein the first channel and the second channel are channels in at least two channels which bear uplink information in a first time period, and the sum of the initial power of the at least two channels is greater than the power threshold of the terminal equipment;

in this embodiment of the present application, a terminal device determines transmission powers of a first channel and a second channel according to priorities of the first channel and the second channel, where the first channel and the second channel are channels of at least two channels that carry uplink information in a first time period, and a sum of initial powers of the at least two channels is greater than a power threshold of the terminal device. The power threshold of the terminal device refers to the maximum value allowed by the sum of the powers of the at least two channels transmitted by the terminal device. Optionally, the power threshold is related to at least one of a type of the terminal device, a power backoff indicator of the terminal device, positions of frequency resources occupied by the at least two channels, a modulation method used by the at least two channels to send uplink information, and the like.

In a scenario where the sum of the initial powers of the at least two channels carrying the uplink information is greater than the power threshold of the terminal device, then, the terminal device cannot support at least that the uplink information carried by each channel is sent according to the respective initial sending powers within the time overlapping by the at least two channels, so that the terminal device needs to determine the sending power used for carrying the uplink information on each channel according to the priorities of the at least two channels, so that the sum of the sending powers of the first channel, the second channel, and other channels in the at least two channels is less than or equal to the power threshold. That is, the terminal device needs to sequentially reduce the transmission power of the channels according to the priority of each channel and the order from low to high of the priority, and determine the transmission power of each channel, so that the sum of the reduced transmission powers of each channel is not greater than the power threshold of the terminal device.

Assuming that the at least two channels include L (L ≧ 2) channels and the sum of the initial powers of the at least two channels including the first channel and the second channel is Q, i.e., Q

Wherein P is_iIs the initial power of the ith channel in the first set of channels.

Assume that the initial transmit power of the first channel is P₁The initial transmission power of the second channel is P₂The sum Q of the initial powers of the at least two channels is greater than the power threshold Q' of the terminal device. Taking the second channel with higher priority than the first channel as an example, the terminal device determines the transmission power of the first channel as P according to the priority₁', wherein P₁'＝W₁×P₁Wherein W is not less than 0₁Is less than 1. If W is₁A value between 0 and 1 can satisfy P₁'+P₂And the sum of the transmission power of the other channels except the first channel and the second channel in the at least two channels is not more than Q', the terminal equipment determines the transmission power of the second channel to be P₂. I.e. the terminal device determines the transmission power of the first channel as P₁'＝W₁×P₁The transmission power of the second channel is P₂. If W is₁Any value between 0 and 1 does not satisfy P₁'+P₂And the transmission power of other channels except the first channel and the second channel in the at least two channels is not more than Q', the terminal equipment determines the transmission power of the first channel to be P₁' 0, and the transmission power of the second channel is P₂'＝W₂×P₂Wherein W is not less than 0₂< 1 such that P₁'+P₂And the transmission power of the other channels except the first channel and the second channel in the at least two channels is not more than Q'. If the priority of the first channel is higher than that of the second channel, the method for the terminal device to determine the transmission power of the first channel and the transmission power of the second channel according to the priority is similar and derivable, and is not repeated here. If the priority of the first channel is equal to the second channelOn the other hand, assume that the initial transmission power of the first channel is P₁The initial transmission power of the second channel is P₂The sum Q of the initial powers of the at least two channels is greater than the power threshold Q' of the terminal device. The terminal equipment determines the transmission power of the first channel to be P according to the priority₁' determining the transmission power of the second channel as P₂', wherein P₁'＝W×P₁，P₂'＝W×P₂Wherein W is more than or equal to 0 and less than 1. The value of W can satisfy P₁'+P₂'and the sum of the transmission power of the other channels except the first channel and the second channel among the at least two channels is not more than Q'.

Illustratively, it is assumed that the terminal device has 2 channels carrying uplink information in a first time period, and the initial power of the first channel is P₁The initial power of the second channel is P₂The power threshold of the terminal device is Q', Q ═ P₁+P₂Q', then the terminal device can determine the transmission power of the first channel and the second channel as P according to the priority of the first channel and the second channel₁' and P₂' if the priority of the second channel is higher than the priority of the first channel, it may include ① if P₂> Q', then the transmission power P of the first channel₁' 0, the transmission power P of the second channel needs to be reduced₂'＝W₂×P₂Wherein W is not less than 0₂< 1 such that P₂'< Q'; ② if P₂Q', then the transmission power P of the first channel₁' 0, transmission power P of the second channel₂'＝W₂×P₂Wherein W is not less than 0₂< 1 such that P₂'< Q'; ③ if P₂< Q', then the transmission power P of the first channel₁'＝W₁×P₁Wherein W is not less than 0₁< 1, transmission power P of the second channel₂'＝W₂×P₂，P₂'≤P₂Wherein W is not less than 0₂< 1 such that P₂'+P₁'≤Q'。

Suppose that the terminal device has 3 channels for carrying uplink information in a first time period, and the initial power of the first channel is P₁The initial power of the second channel is P₂The initial power of the third channel is P₃The power threshold of the terminal device is Q', Q ═ P₁+P₂+P₃If the priority of the third channel is higher than that of the second channel, the priority of the second channel is higher than that of the first channel, ① if P is higher than that of the first channel₃> Q', then the transmission power P of the first channel₁' 0, transmission power P of the second channel₂' also 0, the transmission power P of the third channel needs to be reduced₃'＝W₃×P₃Wherein W is not less than 0₃< 1 such that P₃'< Q'; ② if P₃Q', then the transmission power P of the first transmission channel₁' 0, transmission power P of the second channel₂' 0, transmission power P of the third channel₃'＝W₃×P₃，0≤W₃< 1 such that P₃'< Q'; ③ if P₃< Q', then, if P₃+P₂> Q', the transmission power P of the first channel₁' 0, transmission power P of the second channel₂'＝W₂×P₂Wherein W is not less than 0₂< 1, transmission power P of the third channel₃'≤P₃Wherein W is not less than 0₃< 1 such that P₃'+P₂'is less than or equal to Q'; if P₃+P₂Q', transmission power P of the first channel₁' 0, transmission power P of the second channel₂'＝W₂×P₂Wherein W is not less than 0₂< 1, transmission power P of the third channel₃'≤P₃Wherein W is not less than 0₃< 1 such that P₃'+P₂'is less than or equal to Q'; if P₃+P₂> Q', the transmission power P of the first channel₁'＝W₁×P₁Wherein W is not less than 0₁< 1, transmission power P of the second channel₂'＝W₂×P₂Wherein W is not less than 0₂< 1, transmission power P of the third channel₃'≤P₃Wherein, in the step (A),0≤W₃< 1 such that P₃'+P₂'+P₁'≤Q'。

In the following exemplary description, the terminal device may be exemplified by a user equipment UE, and the access network device may be exemplified by a base station. In this embodiment, the priority status of the first channel and the second channel may be any one of the following:

(1) the priority of the second channel is higher than that of the first channel, wherein the uplink information borne on the first channel comprises uplink data, and the uplink information borne on the second channel comprises NACK feedback information corresponding to the downlink data received by the terminal equipment.

And if the second channel carries NACK feedback information of the UE on the received downlink data, the first channel carries uplink data. Due to the higher delay requirement caused by the urgent URLLC service, if the control information transmitted in the second channel includes NACK feedback information corresponding to downlink URLLC data, the base station retransmits the information packet of the previous downlink URLLC data to the UE by receiving the NACK feedback information transmitted by the UE, so that the downlink URLLC service can meet the specified reliability requirement within the specified delay requirement. Therefore, if the second channel carries NACK feedback information corresponding to downlink data received by the terminal device, the priority of the second channel may be higher than that of the first channel, so that the transmission of uplink information of the UE meets the requirements of low latency and high reliability of the downlink URLLC service.

It should be noted that, if there are multiple types of uplink information carried in the uplink channel, the priority of the uplink channel is determined by the uplink information with the highest priority in the uplink information carried in the uplink channel. By using the method in this embodiment (1), in the same channel, the priority of NACK feedback information corresponding to downlink data received by the terminal device is higher than the priority of uplink data.

Optionally, the first channel is a channel used by the UE to transmit scheduling-free uplink data.

Optionally, the first channel is an uplink shared channel, and the second channel is an uplink control channel.

Optionally, the NACK feedback information carried on the second channel is NACK feedback information corresponding to first type downlink data, where the first type downlink data is downlink data whose delay requirement is smaller than a first threshold.

(2) The priority of the first channel is higher than that of the second channel, wherein the uplink information borne on the first channel comprises uplink data, and the uplink information borne on the second channel comprises ACK feedback information corresponding to the downlink data received by the terminal equipment.

If the second channel carries ACK feedback information of the UE for the received downlink data, the UE sends the ACK feedback information to the base station to indicate that a packet of the downlink URLLC data sent by the base station to the UE is received correctly at the UE side. Then, even if the UE does not send ACK feedback information to the base station immediately at present, it will not affect the performance of the downlink URLLC service that meets the specified reliability requirement within the specified delay requirement. Therefore, in this case, the priority of the second channel is higher than that of the first channel, which can ensure that the uplink URLLC service is a higher delay requirement caused by service emergency to some extent.

It should be noted that, if there are multiple types of uplink information carried in the uplink channel, the priority of the uplink channel is determined by the uplink information with the highest priority in the uplink information carried in the uplink channel. By adopting the method of the embodiment (2), in the same channel, the priority of the uplink data is higher than the priority of the ACK feedback information corresponding to the downlink data received by the terminal device.

Optionally, the ACK feedback information carried on the second channel is ACK feedback information corresponding to first type downlink data, where the first type downlink data is downlink data whose delay requirement is smaller than a first threshold.

(3) If the uplink information borne on the first channel comprises NACK feedback information corresponding to downlink data received by the terminal equipment, and the uplink information borne on the second channel comprises the uplink data, the priority of the first channel is higher than that of the second channel; if the uplink information carried on the first channel includes ACK feedback information corresponding to the downlink data received by the terminal device, and the uplink information carried on the second channel includes uplink data, the priority of the second channel is higher than that of the first channel.

And if the first channel carries NACK feedback information of the UE on the received downlink data, the second channel carries uplink data. Due to the higher delay requirement caused by the urgent URLLC service, if the control information transmitted in the first channel includes NACK feedback information corresponding to downlink URLLC data, the base station retransmits the information packet of the previous downlink URLLC data to the UE by receiving the NACK feedback information transmitted by the UE, so that the downlink URLLC service can meet the specified reliability requirement within the specified delay requirement. Therefore, if the first channel carries NACK feedback information corresponding to downlink data received by the terminal device, the priority of the first channel may be higher than that of the second channel, so that the transmission of uplink information of the UE meets the requirements of low-latency high reliability of the downlink URLLC service.

If the first channel carries ACK feedback information of the UE for the received downlink data, the UE sends the ACK feedback information to the base station to indicate that a packet of the downlink URLLC data sent by the base station to the UE is received correctly at the UE side. Then, even if the UE does not send ACK feedback information to the base station immediately at present, it will not affect the performance of the downlink URLLC service that meets the specified reliability requirement within the specified delay requirement. Therefore, in this case, the priority of the second channel is higher than that of the first channel, which can ensure that the uplink URLLC service is a higher delay requirement caused by service emergency to some extent.

Therefore, when the uplink control information transmitted by the UE is ACK feedback information for the received downlink data, the priority of the channel carrying the uplink control information is lower than the priority of the channel carrying the uplink data, and when the uplink control information transmitted by the UE is NACK feedback information for the received downlink data, the priority of the channel carrying the uplink control information is higher than the priority of the channel carrying the uplink data. Therefore, the method is beneficial to simultaneously considering the service requirements of low time delay and high reliability of the downlink URLLC and the uplink URLLC.

It should be noted that, if there are multiple types of uplink information carried in the uplink channel, the priority of the uplink channel is determined by the uplink information with the highest priority in the uplink information carried in the uplink channel. By adopting the method in this embodiment (3), in the same channel, the priority of NACK feedback information corresponding to downlink data received by the terminal device is higher than the priority of uplink data, and the priority of uplink data is higher than the priority of ACK feedback information corresponding to downlink data received by the terminal device.

Optionally, the second channel is a channel used by the UE to transmit scheduling-free uplink data.

Optionally, the second channel is an uplink shared channel, and the first channel is an uplink control channel.

Optionally, the NACK feedback information and/or the ACK feedback information carried on the second channel is NACK feedback information and/or ACK feedback information corresponding to the first type of downlink data, where the first type of downlink data is downlink data whose delay requirement is smaller than a first threshold.

(4) If the uplink information borne on the first channel comprises first type channel state feedback information corresponding to downlink data received by the terminal equipment, and the uplink information borne on the second channel comprises uplink data, the priority of the first channel is higher than that of the second channel, and the first type channel state feedback information is channel state information obtained by the terminal equipment according to a reference signal corresponding to the received first downlink data;

if the uplink information carried on the first channel includes second-type channel state feedback information corresponding to downlink data received by the terminal device, and the uplink information carried on the second channel includes uplink data, the priority of the second channel is higher than that of the first channel, and the second-type channel state feedback information is periodic channel state feedback information or semi-continuous channel state feedback information, or channel state information sent by the terminal device according to received channel state information feedback parameters.

The channel state feedback information sent by the UE has different types:

the first type of channel state feedback information is channel state information obtained by the UE according to a reference signal corresponding to the received first downlink data. Optionally, the UE may obtain the first type of channel state information without demodulating and decoding the first downlink data. Before demodulating and decoding the first downlink data and obtaining the HARQ-ACK information of the data, the UE can quickly obtain the first type channel state information through the reference signal corresponding to the data. The base station can rapidly adjust the scheduling parameter of the downlink data transmission after the data according to the first type channel state information by acquiring the first type channel state information sent by the UE, so as to meet the requirements of low time delay and high reliability of the downlink URLLC data transmission. The transmission quality is greatly improved by timely feedback of the first type channel state information and adjustment which possibly occurs according to the feedback, and the service quality of the downlink URLLC service can be improved. Optionally, the UE determines to send the first type channel state feedback information according to the received first type downlink data. Optionally, the first type of downlink data is data of a first service type.

The second type of channel state feedback information is periodic channel state feedback information, or semi-continuous channel state feedback information, or channel state information sent by the UE according to the received channel state information feedback parameter. The base station indicates the UE to send periodic channel state information by configuring the period, time offset and the like of the UE for feeding back the channel state information. The periodic channel state information is measured according to a preset channel state information reference resource. Or the base station configures the period for the UE to feed back the channel state information, and indicates the UE to start feeding back the semi-continuous channel state information through the feedback activation signaling. Although the base station may adjust the scheduling parameter of the downlink data transmission through the second type of channel state feedback information sent by the UE, the second type of channel state information may not reflect the immediate situation of the channel state in time, so that it is difficult to meet the requirements of low latency and high reliability of downlink URLLC data transmission.

And if the first channel carries the second type channel state feedback information, the second channel carries uplink data. And if the control information transmitted in the first channel comprises second-type channel state feedback information, the base station adjusts the scheduling information of downlink data transmitted by the UE in the subsequent scheduling by receiving the second-type channel state feedback information transmitted by the UE. Therefore, if the first channel carries the second type channel state feedback information, the influence on the reliability requirement within the delay requirement of the downlink URLLC data is not large, and therefore, the priority of the first channel may be lower than that of the second channel, so that the transmission of the uplink information of the UE meets the low-delay high-reliability requirement of the uplink URLLC service.

Therefore, when the uplink control information sent by the UE is the second type of channel state feedback information, the priority of the channel carrying the uplink control information is lower than the priority of the channel carrying the uplink data, and when the uplink control information sent by the UE is the first type of channel state feedback information, the priority of the channel carrying the uplink control information is higher than the priority of the channel carrying the uplink data. Therefore, the method is beneficial to simultaneously considering the service requirements of low time delay and high reliability of the downlink URLLC and the uplink URLLC.

It should be noted that, if there are multiple types of uplink information carried in the uplink channel, the priority of the uplink channel is determined by the uplink information with the highest priority in the uplink information carried in the uplink channel. By adopting the method of the embodiment (4), in the same channel, the priority of the first type channel state feedback information is higher than that of the uplink data, and the priority of the uplink data is higher than that of the second type channel state feedback information; or the priority of the first type channel state feedback information is higher than that of the second type channel state feedback information, and the first type channel state feedback information is irrelevant to uplink data.

Optionally, the first type channel state feedback information carried on the first channel is channel state information obtained by a reference signal corresponding to the first type downlink data, where the first type downlink data is downlink data whose delay requirement is smaller than a first threshold.

(5) The priority of the first channel is higher than that of the second channel, wherein the uplink information borne on the first channel comprises uplink data, and the uplink information borne on the second channel comprises HARQ-ACK feedback information and/or channel state information corresponding to the downlink data received by the terminal equipment.

Illustratively, since URLLC service is a higher delay requirement caused by service emergency, the uplink control information transmitted in the second channel includes HARQ-ACK feedback information and/or channel state information corresponding to downlink URLLC data. It should be understood that the HARQ-ACK feedback information herein includes ACK feedback information or NACK feedback information or DTX feedback information. However, no matter the uplink control information includes HARQ-ACK feedback information and/or channel state information, at least the base station has sent downlink URLLC data to the UE. And for the first channel, if the priority of the first channel is lower than that of the second channel, the UE has no opportunity to continuously send uplink URLLC data. In this case, the priority of the first channel may be set to be higher than that of the second channel, which is beneficial to meet the service requirements of low latency and high reliability of the uplink URLLC data.

It should be noted that, if there are multiple types of uplink information carried in the uplink channel, the priority of the uplink channel is determined by the uplink information with the highest priority in the uplink information carried in the uplink channel. By adopting the method of the embodiment (5), in the same channel, the priority of the first type channel state feedback information is higher than that of the uplink data, and the priority of the uplink data is higher than that of the second type channel state feedback information; or the priority of the HARQ-ACK feedback information and/or the channel state information corresponding to the downlink data is higher than that of the uplink data.

Optionally, the UE may obtain the first type of channel state information without demodulating and decoding the first downlink data. Before demodulating and decoding the first downlink data and obtaining the HARQ-ACK information of the data, the UE can quickly obtain the first type channel state information through the reference signal corresponding to the data. The base station can rapidly adjust the scheduling parameter of the downlink data transmission after the data according to the first type channel state information by acquiring the first type channel state information sent by the UE, so as to meet the requirements of low time delay and high reliability of the downlink URLLC data transmission. The transmission quality is greatly improved by timely feedback of the first type channel state information and adjustment which possibly occurs according to the feedback, and the service quality of the downlink URLLC service can be improved. Similarly, the demodulation and decoding of the first downlink data or other downlink data received and the HARQ-ACK information obtained by the UE also play an important role in the decision of the base station on the scheduling parameters for scheduling downlink data transmission and downlink data packets for transmission for the downlink data after the current time. In this case, the priority of the first channel may be set to be equal to the priority of the second channel, which is beneficial to meet the service requirements of low latency and high reliability of URLLC data.

It should be noted that, if there are multiple types of uplink information carried in the uplink channel, the priority of the uplink channel is determined by the uplink information with the highest priority in the uplink information carried in the uplink channel. By using the method in this embodiment (6), in the same channel, the priority of the first type channel state feedback information is equal to the priority of the HARQ-ACK feedback information corresponding to the downlink data.

(7) The priority of the second channel is higher than that of the first channel, wherein the deadline time of the uplink information carried on the first channel is later than the deadline time of the uplink information carried on the second channel, or the remaining number of repeated transmissions of the data corresponding to the uplink information carried on the first channel is greater than the number of repeated transmissions of the data corresponding to the uplink information carried on the second channel.

It should be noted that the first channel and the second channel may both be PUSCHs, or one of the first channel and the second channel is a PUCCH, and the other is a PUSCH, or both of the first channel and the second channel are PUCCHs.

Both downlink transmission and uplink transmission may require multiple transmissions to meet the high reliability requirement of the 5G URLLC service. But URLLC may simultaneously require that the uplink and downlink user plane delay cannot exceed 0.5 ms. Therefore, if the delay upper limit of uplink or downlink is exceeded by excessive repeated transmission, it is not meaningful for URLLC service. Accordingly, if the traffic corresponding to the first of the two uplink channels is the remaining time of the deadline time for the delay requirement, the second channel is only the first transmission of the multiple transmissions. In this case, the first channel may be sent preferentially, that is, the corresponding uplink information is sent on the first channel, so as to meet the service requirement of the service corresponding to the first channel. The UE still has an opportunity to retransmit the second channel before the expiration time of the second channel. Therefore, it is also possible that the UE determines the priority of the first channel and the second channel based on the remaining time of the deadline for the arrival delay (latency) requirement. Specifically, the less the remaining time, the higher the priority. However, in the embodiment shown in fig. 4, if the deadline of the uplink information carried on the first channel is not equal to the deadline of the uplink information carried on the second channel, the implementation manner of (7) above may be performed, and if the deadline of the uplink information carried on the first channel is equal to the deadline of the uplink information carried on the second channel, any one of the following possible implementation manners (8) to (12) may be performed. Or, if the remaining number of times of retransmission of the data corresponding to the uplink information carried on the first channel is not equal to the number of times of retransmission of the data corresponding to the uplink information carried on the second channel, the implementation manner of (7) above may be performed, and if the remaining number of times of retransmission of the data corresponding to the uplink information carried on the first channel is not equal to the number of times of retransmission of the data corresponding to the uplink information carried on the second channel, any one of the following possible implementation manners of (8) to (12) may be performed.

It should be understood that the remaining time of the cutoff time may be simply referred to herein as the cutoff time, and the specific method is as follows:

here, "priority is determined according to the remaining time of the deadline required for reaching the delay," and according to different channels, the deadline referred to corresponds to the uplink information carried in the channel.

1. If one channel carries the HARQ-ACK feedback information and/or the channel state information, the deadline corresponding to the uplink information on the channel is the deadline of the downlink data information block corresponding to the HARQ-ACK feedback information. The downlink data information block may be a Transport Block (TB), a Code Block (CB), or a Code Block Group (CBG), where the CB includes a group of information bits, and the group of information bits are used together for channel coding at a time, or the group of information bits are channel coded together by the sending device, and correspond to a bit block after channel coding; the CBG at least comprises one coding block and can comprise a plurality of coding blocks; the TB includes at least one CB and may also include at least one CBG, which is not limited in this application. Assuming that the time delay requirement of the PDSCH information block is 1ms, the expiration time of the PDSCH information block is 1ms after the beginning of the initial transmission of the PDSCH. The 'remaining time of the deadline according to the arrival delay requirement' of the channel for sending the HARQ-ACK feedback information and/or the channel state information of the downlink data information block is the remaining time of the time position distance of the downlink data information block corresponding to the channel from the deadline. Or, if one channel carries HARQ-ACK feedback information and/or channel state information, the deadline corresponding to the channel is the deadline of the HARQ-ACK feedback information. Considering the time delay requirement of the downlink data information block, the terminal equipment needs to feed back the HARQ-ACK information before the deadline time of the HARQ-ACK feedback information, and the HARQ-ACK information has significance for realizing the service requirement of the downlink URLLC service. Therefore, if one channel carries HARQ-ACK feedback information and/or channel state information, the deadline corresponding to the uplink information on the channel is the deadline of HARQ-ACK.

As shown in fig. 5(a), the expiration time of uplink information carried on the PUCCH is illustrated. The time delay requirement of the downlink data PDSCH information block is that the transmission error rate is below 0.001% in 1 ms. D1-D5 are 5 repeated transmissions of one PDSCH information block. For PUCCH at U1, it corresponds to the first transmission of PDSCH information block D1. D1 is the first transmission of the downstream data. D1 is 1ms away from the expiration time of the PDSCH information block, and the remaining time of the expiration time of the arrival delay requirement corresponding to the PUCCH at U1 is 1 ms. Likewise, for PUCCH at U3, it corresponds to D4 of the PDSCH information block. D4 is the fourth transmission of the downstream data. D3 is further (4 × 0.125) ms away from the end time of the PDSCH information block, and the remaining time of the end time required for the arrival delay of the PUCCH at U1 is (8 × 0.125) ms. It should be understood that U1, U2, U3, U4 and U5 herein are uplink control information fed back to downlink data transmitted on the PDSCH channel, i.e., HARQ-ACK feedback information and/or channel state information.

2. For PUSCH based on SR scheduling

2.1 for the first upstream packet of URLLC. The corresponding deadline is the deadline of the PUSCH information block determined by the UE when the SR starts to be transmitted. The uplink data PUSCH information block may be a Transport Block (TB), a Coding Block (CB), or a Coding Block Group (CBG), where the CB includes a group of information bits, and the group of information bits are used together for channel coding at a time, or the group of information bits are channel coded together by the sending device, and correspond to a bit block after channel coding; the CBG at least comprises one coding block and can comprise a plurality of coding blocks; the TB includes at least one CB and may also include at least one CBG, which is not limited in this application. Assuming that the delay requirement of the PUSCH information block is 1ms, the expiration time of the PUSCH information block is 1ms after the UE starts transmitting the SR.

As shown in fig. 5(b), the time-off of the uplink information carried on the PUSCH is illustrated. The time delay requirement of the uplink data PUSCH information block is that the transmission error rate is below 0.001% within 1 ms. U0 is the time when the UE transmits the SR. The expiration time of the delay requirement of the PUSCH is 1ms after the start of U0. U1 corresponds to the time of the first transmission of the PUSCH information block. U1 has a time of (6 × 0.125) ms from the end time of the PUSCH information block, and the remaining time of the end time of the arrival delay requirement for the PUSCH at U1 is (6 × 0.125) ms.

2.2 for the second and subsequent upstream packets of URLLC. The corresponding deadline is the deadline of the PUSCH information block determined by the first transmission of the PUSCH information block by the UE. As shown in fig. 5(c), another diagram of the deadline of the uplink information carried on the PUSCH is shown. The time delay requirement of the uplink data PUSCH information block is that the transmission error rate is below 0.001% within 1 ms. U1 corresponds to the time of the first transmission of the PUSCH information block. If U1 has a time of 1ms from the expiration time of the PUSCH information block, the remaining time of the expiration time of the arrival delay requirement corresponding to the PUSCH at U1 is 1 ms. U3 corresponds to the time of the third transmission of the PUSCH information block. U3 has a time of (4 × 0.125) ms from the end time of the PUSCH information block, and the remaining time of the end time of the arrival delay requirement for the PUSCH at U3 is (4 × 0.125) ms.

3. For PUSCH based on uplink grant free (UL grant free)

The expiration time corresponding to the PUSCH of the UL grant free is the expiration time of the PUSCH block determined when the UE starts to transmit the PUSCH block for the first time. As specified in 2.2.

And the UE determines the priority of the first channel and the second channel according to the residual time of the deadline of the arrival delay requirement. Specific examples are as follows. It is assumed that the transmission delay requirements of the downlink data information block and the uplink data information block of URLLC are both that the transmission error rate is below 0.001% within 1 ms.

For example, the UE determines the priorities of the first channel and the second channel according to the remaining time of the deadline of the arrival delay requirement of the information carried in the channel, as shown in fig. 5(d), for example, in this embodiment, the schematic diagram of determining the priorities of the first channel and the second channel according to the deadline of the uplink information carried in the uplink channel is shown. The first PDSCH and the second PDSCH are two PDSCH information blocks, respectively. The first PDSCH and the second PDSCH can respectively realize the requirements of low time delay and high reliability of URLLC downlink service through multiple transmissions. The first PUCCH and the second PUCCH are used for feeding back HARQ-ACK information of the first PDSCH and the second PDSCH respectively.

In Slot a, a channel to be transmitted by the UE includes a first PUCCH and a PUSCH. The expiration time corresponding to the first PUCCH is the expiration time of the first PDSCH. The first PDSCH is further (5 x 0.125) ms from its off-time. The PUSCH is further (8 x 0.125) ms from its deadline. Thus, in Slot a, the first PUCCH has higher priority than the PUSCH.

In Slot B, the channel to be transmitted by the UE includes a first PUCCH and a PUSCH. The expiration time corresponding to the first PUCCH is the expiration time of the first PDSCH. The first PDSCH is further (3 x 0.125) ms from its off-time. The PUSCH is further (6 x 0.125) ms from its deadline. Therefore, in Slot B, the first PUCCH has higher priority than the PUSCH.

In Slot C, the channel to be transmitted by the UE includes a second PUCCH and a PUSCH. The expiration time corresponding to the second PUCCH is an expiration time of the second PDSCH. The second PDSCH is further (8 x 0.125) ms from its off-time deadline. The PUSCH is further (5 x 0.125) ms away from its deadline. Therefore, in Slot C, the PUSCH has a higher priority than the first PUCCH.

In the diagrams shown in fig. 5(a) to 5(d), the continuity of transmitting the uplink information or the downlink information in one subframe is not limited.

And the UE determines the priority of the first channel and the second channel according to the residual time of the deadline of the arrival delay requirement. The priority of the second channel is higher than that of the first channel, wherein the deadline time of the uplink information carried on the first channel is later than the deadline time of the uplink information carried on the second channel, which is beneficial to simultaneously considering the service requirements of low time delay and high reliability of the downlink URLLC and the uplink URLLC.

Optionally, the priorities of the first channel and the second channel may be determined according to the remaining number of times of retransmission of the data corresponding to the uplink information carried on the first channel and the number of times of retransmission of the data corresponding to the uplink information carried on the second channel. And if the residual repeated transmission times of the data corresponding to the uplink information carried on the first channel are greater than the repeated transmission times of the data corresponding to the uplink information carried on the second channel, the priority of the second channel is higher than that of the first channel. And vice versa.

Both downlink transmission and uplink transmission may require multiple repeated transmissions to meet the high reliability requirement of the 5G URLLC service. But URLLC may simultaneously require that the uplink and downlink user plane delay cannot exceed 0.5 ms. If the service corresponding to the first channel of the two uplink channels reaches the maximum repeated transmission number immediately, the second channel has a plurality of repeated transmission opportunities. In this case, the first channel may be sent preferentially, that is, the corresponding uplink information is sent on the first channel, so as to meet the service requirement of the service corresponding to the first channel. Therefore, the method is beneficial to simultaneously considering the service requirements of low time delay and high reliability of the downlink URLLC and the uplink URLLC.

It should be noted that, if there are multiple types of uplink information carried in the uplink channel, the priority of the uplink channel is determined by the uplink information with the highest priority in the uplink information carried in the uplink channel. With the method of this embodiment (7), the priority of the uplink information with the later deadline is lower than the priority of the uplink information with the earlier deadline on the same channel.

(8) The priority of the second channel is higher than that of the first channel, wherein the uplink information borne on the first channel comprises HARQ-ACK feedback information and/or channel state information corresponding to downlink data received by the terminal equipment, and the uplink information borne on the second channel comprises the uplink data; and the deadline of the uplink information carried on the first channel is equal to the deadline of the uplink information carried on the second channel, or the remaining number of repeated transmissions of the data corresponding to the uplink information carried on the first channel is equal to the number of repeated transmissions of the data corresponding to the uplink information carried on the second channel.

(9) The priority of the second channel is higher than that of the first channel, wherein the uplink information borne on the first channel comprises uplink data, and the uplink information borne on the second channel comprises NACK (negative acknowledgement) feedback information corresponding to the downlink data received by the terminal equipment; and the deadline of the uplink information carried on the first channel is equal to the deadline of the uplink information carried on the second channel, or the remaining number of repeated transmissions of the data corresponding to the uplink information carried on the first channel is equal to the number of repeated transmissions of the data corresponding to the uplink information carried on the second channel.

(10) The priority of the second channel is higher than that of the first channel, wherein the uplink information borne on the first channel comprises ACK feedback information corresponding to the downlink data received by the terminal equipment, and the uplink information borne on the second channel comprises the uplink data; and the deadline of the uplink information carried on the first channel is equal to the deadline of the uplink information carried on the second channel, or the remaining number of repeated transmissions of the data corresponding to the uplink information carried on the first channel is equal to the number of repeated transmissions of the data corresponding to the uplink information carried on the second channel.

(11) If the uplink information carried on the first channel comprises NACK feedback information corresponding to the downlink data received by the terminal equipment, and the uplink information carried on the second channel comprises uplink data, the priority of the first channel is higher than that of the second channel; if the uplink information carried on the first channel includes ACK feedback information corresponding to the downlink data received by the terminal device, and the uplink information carried on the second channel includes uplink data, the priority of the second channel is higher than that of the first channel; and the deadline of the uplink information carried on the first channel is equal to the deadline of the uplink information carried on the second channel, or the remaining number of repeated transmissions of the data corresponding to the uplink information carried on the first channel is equal to the number of repeated transmissions of the data corresponding to the uplink information carried on the second channel.

(12) If the uplink information borne on the first channel comprises first type channel state feedback information corresponding to downlink data received by the terminal equipment, and the uplink information borne on the second channel comprises uplink data, the priority of the first channel is higher than that of the second channel, and the first type channel state feedback information is channel state information obtained by the terminal equipment according to a reference signal corresponding to the received first downlink data; if the uplink information carried on the first channel includes second-type channel state feedback information corresponding to downlink data received by the terminal device, and the uplink information carried on the second channel includes uplink data, the priority of the second channel is higher than that of the first channel, and the second-type channel state feedback information is periodic channel state feedback information or semi-continuous channel state feedback information, or channel state information sent by the terminal device according to received channel state information feedback parameters. And the deadline of the uplink information carried on the first channel is equal to the deadline of the uplink information carried on the second channel, or the remaining number of repeated transmissions of the data corresponding to the uplink information carried on the first channel is equal to the number of repeated transmissions of the data corresponding to the uplink information carried on the second channel.

In any of the schemes (8) to (12) above, if the deadline of the uplink information carried on the first channel is equal to the deadline of the uplink information carried on the second channel, or the remaining number of times of retransmission of data corresponding to the uplink information carried on the first channel is equal to the number of times of retransmission of data corresponding to the uplink information carried on the second channel, the priorities of the first channel and the second channel may be determined according to any of the schemes (8) to (12). (8) The specific method descriptions of (9), (10), (11) and (12) can refer to (5), (1), (2), (3) and (4), respectively, and are not described herein again.

(13) The priority of the second channel is higher than that of the first channel, wherein the uplink information borne on the first channel comprises a first uplink data packet, the uplink information borne on the second channel comprises a second uplink data packet, and the arrival time of the second uplink data packet is later than that of the first uplink data packet.

In the scheme (13) above, specifically, the UE determines the priority of the first channel and the priority of the second channel according to the arrival times of the traffic data arriving on the first channel and the second channel, respectively. Specifically, the later the arrival time, the higher the priority. The specific method comprises the following steps:

URLLC requires that the uplink user plane delay cannot exceed 0.5 ms. On the other hand, URLLC traffic generates data packets that are non-periodic bursts. Therefore, during the period when the UE sends the uplink data packet of the first URLLC, the UE may have a need for transmission of the uplink data packet of the second URLLC. Thus, it is possible that the UE needs to transmit two uplink data packets at the same time in one time unit. In this case, if the initial power of the UE is limited, the transmission power of the two channels needs to be determined by priority. As shown in fig. 6(a), it is a schematic diagram that the UE transmits uplink data of a bearer on the first PUSCH and the second PUSCH in the first time period.

The first PUSCH and the second PUSCH are two PUSCH information blocks, respectively. The first PUSCH and the second PUSCH can respectively realize the requirements of low time delay and high reliability of URLLC uplink service through multiple transmissions. The packet arrival times of the first PUSCH and the second PUSCH are different.

In Slot a, a channel to be transmitted by the UE includes a first PUSCH and a second PUSCH. The first PUSCH has been (3 x 0.125) ms away from its packet arrival duration, and the second PUSCH is 0ms away from its packet arrival duration. Thus, in Slot a, the second PUCCH has higher priority than the first PUSCH.

In Slot B, the channel to be transmitted by the UE includes a first PUSCH and a second PUSCH. The first PUSCH has been (6 x 0.125) ms away from its packet arrival duration, and the second PUSCH is (3 x 0.125) ms away from its packet arrival duration. Therefore, in Slot B, the second PUCCH has higher priority than the first PUSCH.

And the UE determines the priority of the first channel and the priority of the second channel according to the arrival time of the service data corresponding to the first channel and the second channel. The requirements of URLLC DL and UL for low delay and high reliability are met. It should be noted that, in the calculation of the "arrival duration" of a certain time slot, the arrival duration of the distance data packet may or may not be counted in the time slot itself, and is not limited specifically.

It should be noted that, if there are multiple types of uplink information carried in the uplink channel, the priority of the uplink channel is determined by the uplink information with the highest priority in the uplink information carried in the uplink channel. With the method of this embodiment (13), the priority of the uplink information with a later arrival time is higher than the priority of the uplink information with an earlier arrival time.

(14) The priority of the second channel is higher than that of the first channel, wherein the first channel is a channel scheduled by the first signaling, the second channel is a channel scheduled by the second signaling, and the time for receiving the first signaling by the terminal equipment is earlier than the time for receiving the second signaling by the terminal equipment. Optionally, the first signaling and the second signaling each include information indicating a time position of the first time period.

The first channel and the second channel are respectively corresponding to physical downlink control information, such as first physical downlink control information and second physical downlink control information. The time for the base station to send the first physical downlink control information is assumed to be a first time, and the time for the base station to send the second physical downlink control information is assumed to be a second time. The first channel has a priority greater than the second channel if the first time is later than the second time. After the base station sends the second physical downlink control information, the base station sends the first physical downlink control information to instruct the UE to send the first channel at the same time as the second channel, and the base station considers the situation that the first channel and the second channel occur simultaneously, so that in this situation, the scheduling policy of the base station for the uplink data of the UE can be embodied by the priority of the second channel being higher than the priority of the first channel. As shown in fig. 6(b), a schematic diagram of determining the priorities of the first channel and the second channel according to the morning and evening of the signaling receiving time is shown for the terminal device.

By using the method of this embodiment (14), the priority of the uplink information corresponding to the later scheduling signaling is higher than the priority of the uplink information corresponding to the earlier scheduling signaling.

And if the scheduling type of the first channel is the signaling-free scheduling and the scheduling type of the second channel is the signaling scheduling, the priority of the second channel is higher than that of the first channel.

After the base station sends the first physical downlink control information, the UE needs to send the second data of the UL grant free at the same time as the first channel according to the arrival condition of the uplink data of the UE, which indicates that the second data is very urgent. Therefore, in this case, the priority of the second channel is higher than that of the first channel, which can embody the low-latency requirement principle of the UE for the uplink URLLC data transmission.

It should be noted that, the determination manner of the priority of the first channel and the second channel includes, but is not limited to, the above-mentioned scheme, and other manners of determining the priority of the first channel and the second channel are also within the scope of the protection of the embodiment of the present application. By adopting the method of this embodiment (15), the priority of the uplink information scheduled by signaling is higher than the priority of the uplink information not scheduled by signaling.

In the schemes (14) and (15) above, the UE determines the priority of the first channel and the second channel according to the scheduling types of the arrival of the first channel and the second channel. Wherein the scheduling types include a signaling scheduling type and a signaling exempt scheduling type.

For uplink data scheduled by signaling, uplink data sent by the uplink data is indicated by physical downlink control information. Optionally, the physical downlink control information includes at least one of a trigger instruction instructing the UE to send uplink data, time and/or frequency resources used by the UE to send uplink data, resources of a reference signal used by the UE to send uplink data, and the like. Optionally, the physical downlink control information further includes time information for the UE to send uplink data. For example, the base station sends the physical downlink control information at the first time, where the physical downlink control information includes time offset information, and after receiving the physical downlink control information, the UE may determine the sending time of the uplink data indicated by the UE according to the first time and the time offset information.

402. The terminal device transmits at least one of the first channel and the second channel according to the transmission power of the first channel and the second channel.

In the embodiment of the application, after the terminal device determines the transmission power of the first channel and the second channel according to the priority of the first channel and the second channel, the terminal device transmits at least one of the first channel and the second channel according to the transmission power of the first channel and the second channel. It should be noted that, sending at least one of the first channel and the second channel is equivalent to sending uplink information of the corresponding bearer on at least one of the first channel and the second channel.

Optionally, the terminal device transmits at least one of the first channel and the second channel according to the transmission power of the first channel and the second channel. And if the transmission power of the first channel and the second channel is greater than 0, the terminal equipment transmits the first channel and the second channel. If the transmission power of only one of the first channel and the second channel is greater than 0, the terminal equipment transmits the channel with the transmission power greater than 0.

It should be noted that the terminal device determines the transmission power of the first channel and the second channel according to the priority of the first channel and the second channel, and transmits at least one of the first channel and the second channel according to the transmission power of the first channel and the second channel. The terminal device transmits at least one of the first channel and the second channel according to the transmission power of the first channel and the second channel, which may mean that the terminal device transmits at least one of the first channel and the second channel in a time when the resources of the first channel and the second channel in time overlap, and how to transmit the first channel and the second channel in a time when the resources of the first channel and the second channel in time do not overlap is not a protection scope of the present invention. For example in the second case of the following figure. The terminal device transmits at least one of the first channel and the second channel for a first period of time according to the transmission power of the first channel and the second channel. And there is no limitation on how the terminal device transmits the first channel at a time other than the first time period. As described above in fig. 3(d) 1, 2, and 6.

Or, the terminal device transmits at least one of the first channel and the second channel according to the transmission power of the first channel and the second channel, which may mean that the terminal device transmits at least one of the first channel and the second channel in the first time period. The first time period may include a time when the resources of the first channel and the second channel in time do not overlap. As in the

cases

3, 4 and 5 in fig. 3 (d).

403. The base station receives at least one of the first channel and the second channel transmitted by the terminal device according to the transmission power of the first channel and the second channel.

In this embodiment of the present application, a terminal device sends at least one of a first channel and a second channel according to sending power of the first channel and the second channel, where the first channel and the second channel are channels of at least two channels that carry uplink information in a first time period, and a sum of initial powers of the at least two channels is greater than a power threshold of the terminal device. Optionally, the access network device determines the transmission power of the first channel and the second channel according to the priority of the first channel and the second channel. It should be understood that, regarding the priorities of the first channel and the second channel, reference may be made to any of (1) - (15) described in step 401, and details are not repeated here.

In the embodiment of the application, the terminal device determines the transmission power of a first channel and a second channel according to the priority of the first channel and the second channel, wherein the first channel and the second channel are channels of at least two channels carrying uplink information in a first time period, and the sum of the initial power of the at least two channels is greater than the power threshold of the terminal device; the terminal device transmits at least one of the first channel and the second channel according to the transmission power of the first channel and the second channel. The problem that when a plurality of uplink channels are transmitted simultaneously, the terminal equipment determines the sending power of each channel according to the priority of each channel can be solved, and the requirements of the URLLC on time delay and reliability in a 5G scene are met. The priority of the first channel and the second channel is described in detail in the above embodiments. The embodiment of the application is more flexible, and the transmission of the uplink information meets the purpose of service delay and reliability requirements.

As shown in fig. 7, a schematic view of an embodiment of a method for sending uplink information in an embodiment of the present application is described with respect to a scenario in which a terminal device cannot send a first channel and a second channel at the same time in a first time period, and includes:

701. the terminal equipment determines a channel with higher priority in the first channel and the second channel;

in the embodiment of the present application, a scenario is applied in which the terminal device cannot simultaneously transmit the first channel and the second channel in the first time period, and a channel with a higher priority in the first time period needs to be determined according to the priorities of the first channel and the second channel. The first channel and the second channel are channels of at least two channels for bearing uplink information in the first time period.

It should be noted that, the UE determines that the uplink information of the bearer cannot be simultaneously sent on the first channel and the second channel, and the specific case may be that the UE receives the configuration information sent by the base station, where the configuration information indicates that the UE cannot simultaneously send the uplink information of the bearer on the first channel and the second channel, or that the configuration case of the UE itself does not support the simultaneous sending of the uplink information of the bearer on the first channel and the second channel.

Illustratively, if the priority of the first channel is higher than that of the second channel, the UE transmits the uplink information of the bearer to the base station on the first channel, and if the priority of the second channel is higher than that of the first channel, the UE transmits the uplink information of the bearer to the base station on the second channel. It should be understood that, in practical application, before the uplink information of the bearer is sent on the channel with a higher priority, it may also need to determine whether the sum of the initial power of the channel and the initial powers of other channels sent simultaneously is greater than the power threshold of the UE, and if so, it may also need to reduce the sending power of the channel so that the sending power of the channels sent simultaneously is less than or equal to the power threshold of the UE, and then send the uplink information of the bearer according to the sending power; if the number of the uplink information is less than or equal to the number of the uplink information, the uplink information can be directly sent on the channel without reduction.

In this embodiment, the priority status of the first channel and the second channel may be any one of the following:

(5) The priority of the first channel is higher than that of the second channel, the uplink information borne on the first channel comprises uplink data, and the uplink information borne on the second channel comprises HARQ-ACK feedback information and/or channel state information corresponding to the downlink data received by the terminal equipment;

wherein the first channel is a schedule-free channel; and/or, transmitting a higher priority channel of the first channel and the second channel during the first time period comprises: and sending the first channel in the first time period, wherein the uplink information sent on the first channel does not comprise HARQ-ACK feedback information and/or channel state information corresponding to the downlink data received by the terminal equipment.

In the scheme (5) above, if the PUSCH is a scheduling-free channel and is used for carrying uplink data; if the PUCCH carries HARQ-ACK information and/or channel state information corresponding to downlink data received by the UE; then the priority of PUSCH is higher than the priority of PUCCH.

Or, if the PUSCH is a scheduling-free channel and is used for carrying uplink data and is not used for carrying uplink control information, the uplink control information includes HARQ-ACK information and/or channel state information corresponding to downlink data received by the UE; if the PUCCH carries HARQ-ACK information and/or channel state information corresponding to downlink data received by the UE; then the priority of PUSCH is higher than the priority of PUCCH.

Or, if the PUSCH is used for carrying uplink data and is not used for carrying uplink control information, the uplink control information includes HARQ-ACK information and/or channel state information corresponding to downlink data received by the UE; if the PUCCH carries HARQ-ACK information and/or channel state information corresponding to downlink data received by the UE; then the priority of PUSCH is higher than the priority of PUCCH.

In the above scheme (7), for determining the deadline, reference may be made to schematic diagrams shown in fig. 5(a) -5(d) in the embodiment shown in fig. 4, and details of the determination of the deadline of the PUCCH and the determination of the deadline of the PUSCH are not described herein again. It is to be understood that in the possibility of embodiment (7) shown in fig. 7, a case is considered where the deadline of the upstream information carried on the first channel is later than the deadline of the upstream information carried on the second channel. Here, the uplink information carried in the first channel and the uplink information carried in the second channel are not particularly limited.

1) The deadline of the uplink information carried on the first channel is later than the deadline of the uplink information carried on the second channel, and the priority of the second channel is higher than the priority of the first channel, which is specifically described as follows:

assuming that there is (5 x 0.125) ms remaining for the deadline carried on the PUCCH channel and (3 x 0.125) ms remaining for the deadline carried on the PUSCH channel, the priority of the second channel is higher than the priority of the first channel.

2) The remaining number of repeated transmissions of data corresponding to the uplink information carried on the first channel is greater than the number of repeated transmissions of data corresponding to the uplink information carried on the second channel, and the priority of the second channel is higher than the priority of the first channel, which is specifically described as follows:

assuming that the remaining number of transmissions of the uplink information transmitted in the PUCCH is 5 times and the remaining number of transmissions of the uplink information transmitted in the PUSCH is only 2 times, the priority of the PUSCH is higher than that of the PUCCH.

It should be noted that, in any one of the possibilities of embodiments (8) to (12) shown in fig. 7, a case where the deadline of the uplink information carried on the first channel is equal to the deadline of the uplink information carried on the second channel is considered, or a case where the remaining number of times of retransmission of data corresponding to the uplink information carried on the first channel is equal to the number of times of retransmission of data corresponding to the uplink information carried on the second channel is considered, and for the deadline, specific reference may be made to fig. 5(a) -5(d), which is not described herein again.

(14) The priority of the second channel is higher than that of the first channel, wherein the first channel is a channel scheduled by the first signaling, the second channel is a channel scheduled by the second signaling, and the time of receiving the first signaling by the UE is earlier than that of receiving the second signaling by the UE. Optionally, the first signaling and the second signaling each include information indicating a time position of the first time period.

It should be noted that, in the schemes described in (1) to (12), one of the first channel and the second channel is a channel used for transmitting uplink data, for example, a PUSCH, and the other is a channel used for transmitting uplink control information, for example, a PUCCH, and how the UE determines the priority of the first channel and the second channel; in the schemes described in (13) to (15) above, the first channel and the second channel are both channels used for transmitting uplink data, for example, PUSCH, and how the UE determines the priority of the first channel and the second channel.

In the above technical solutions (1) - (4), (6) - (15), (1) - (4) and (6) - (15) are similar to the descriptions of (1) - (4) and (6) - (15) in step 401 in embodiment 4, and reference may be made to the detailed description of step 401, which is not repeated herein.

It should be noted that, the determination manner of the priority of the first channel and the second channel includes, but is not limited to, the above-mentioned several schemes, and other manners of determining the priority of the first channel and the second channel are also within the scope of the protection of the embodiment of the present application.

702. The terminal equipment transmits the channel with higher priority.

In the embodiment of the application, after the terminal device determines the channel with higher priority in the first channel and the second channel, the terminal device sends the channel with higher priority. It should be noted that, sending at least one of the first channel and the second channel is equivalent to sending uplink information of a corresponding bearer on at least one of the first channel and the second channel.

It should be noted that, when the terminal device transmits the channel with higher priority, it may refer to that the terminal device transmits the channel with higher priority in a time when the resources of the first channel and the second channel overlap in time, and how to transmit the first channel and the second channel in a time when the resources of the first channel and the second channel do not overlap in time is not the protection scope of the present application. Such as the 2 nd case shown in fig. 3(d) described above. The terminal device transmits at least one of the first channel and the second channel for a first period of time according to the transmission power of the first channel and the second channel. And there is no limitation on how the terminal device transmits the first channel at a time other than the first time period.

Optionally, if the terminal device determines that the channel with higher priority in the first channel and the second channel is the second channel, the terminal device sends the second channel within a time period in which the resources of the first channel and the second channel overlap in time. The terminal equipment can send the uplink information carried by the first channel at other times than the time overlapping with the resource of the second channel in time. Alternatively, the terminal device may send the uplink information carried by the second channel at other times than the time overlapping with the resource of the first channel.

As shown in fig. 6(c), a diagram of transmitting a channel with higher priority from among the first channel and the second channel is shown; for example, the resources of the first channel are the resources within T1 in time, the resources of the second channel are the resources within T2 in time, and the time at which the resources of the first channel and the second channel overlap in time is T2. And if the UE determines that the priority of the second channel is higher than that of the first channel, the UE transmits the uplink information carried by the second channel at the time of T2 and transmits the uplink information carried by the first channel on part of resources of the first channel within the time of T3.

If the first channel is an uplink channel without scheduling, the access network device generally configures a first channel resource for transmitting uplink information for the UE in advance. But the access network equipment does not know when the UE will occupy the first channel resource to transmit uplink information. Thus. Generally, when the UE occupies the first channel resource to send data of the UL grant free, the UE first sends a reference signal, which is convenient for the access network device to detect that the UE occupies the first channel resource to send data. Or the reference signal transmitted by the UE in the first channel resource may also be used for functions such as channel estimation for demodulation of uplink information of the UL grant free, uplink transmission timing adjustment, and the like. But as shown in this embodiment if the first channel has a lower priority than the second channel during the first time period. The UE can only occupy the resources of the first channel at other times than the first time period. Thus, the UE can transmit only the second channel during the first time period according to the priorities of the first channel and the second channel. On other resources of the first channel except for the first time period. The UE still needs to send the reference signal first to satisfy the requirement that the access network device obtains the uplink information that the UE sent the ul grant free through reference signal detection, and executes other functions of the reference signal. Therefore, the priority of the first channel and the second channel in the first time period will affect the content of the uplink information transmitted in the first channel.

Fig. 6(d) is a schematic diagram of a transmission format of a first channel in the embodiment of the present application; a shows the transmission format of the first channel. Wherein the former resource is used for UE to send reference, and the latter resource is used for UE to send uplink data. However, as shown in fig. 6(e), it is a schematic diagram that the higher priority of the first channel and the second channel is sent in the first time period in the embodiment of the present application. If the former resources of the first channel and the resources of the second channel overlap in time, the second channel has a higher priority than the first channel, and the UE cannot transmit the first channel and the second channel at the same time. The UE transmits the second channel within a time in which the resources of the first channel and the second channel overlap in time. And transmitting the reference signal and the uplink data on the remaining resources of the first channel. Optionally, the first channel is a channel without scheduled uplink data. Optionally, the first time period is a time when the resources of the first channel and the second channel overlap in time. The UE transmits the second channel and does not transmit the first channel for the first period of time. And the UE sends the uplink information carried by the first channel on the resources of the first channel except the first time period. Optionally, the sending, by the UE, the uplink information carried by the first channel in the resources of the first channel except the first time period includes sending, by the UE, the reference signal in the resources of the first channel except the first time period first.

703. And the access network equipment receives a channel with higher priority in the first channel and the second channel sent by the terminal equipment.

In this embodiment of the present application, a channel with a higher priority among a first channel and a second channel sent by a receiving terminal device is a channel of at least two channels that carry uplink information in a first time period, and the terminal device cannot send the first channel and the second channel at the same time in the first time period. It should be understood that, regarding the priorities of the first channel and the second channel, reference may be made to any of (1) - (15) described in step 701, and details are not repeated here.

In the embodiment of the application, the terminal device determines a channel with a higher priority in a first channel and a second channel, where the first channel and the second channel are channels of at least two channels that carry uplink information in a first time period, and the UE cannot simultaneously send the first channel and the second channel in the first time period. The terminal equipment transmits the channel with higher priority. And the access network equipment receives a channel with higher priority in the first channel and the second channel sent by the terminal equipment. The method can solve the problem that when the UE does not support two channels to simultaneously send the carried uplink information, the channel with higher priority is selected to send the carried uplink information, thereby meeting the requirements of the URLLC on time delay and reliability. The priority of the first channel and the second channel is described in detail in the above embodiments.

Referring to fig. 13, the handset includes: radio Frequency (RF) circuitry 1310, memory 1320, input unit 1330, display unit 1340, sensor 1350, audio circuitry 1360, wireless fidelity (WiFi) module 1370, processor 1380, and power supply 1390. Those skilled in the art will appreciate that the handset configuration shown in fig. 13 is not intended to be limiting and may include more or fewer components than those shown, or some components may be combined, or a different arrangement of components.

The following describes each component of the mobile phone in detail with reference to fig. 13:

RF circuit 1310 may be used for receiving and transmitting signals during a message transmission or call, and in particular, for processing received downlink information of a base station by processor 1380; in addition, the data for designing uplink is transmitted to the base station. In general, the RF circuit 1310 includes, but is not limited to, an antenna, at least one amplifier, a transceiver, a coupler, a Low Noise Amplifier (LNA), a duplexer, and the like. In addition, RF circuit 1310 may also communicate with networks and other devices via wireless communication. The wireless communication may use any communication standard or protocol, including but not limited to global system for Mobile communications (GSM), General Packet Radio Service (GPRS), Code Division Multiple Access (CDMA), Wideband Code Division Multiple Access (WCDMA), Long Term Evolution (LTE), email, Short Messaging Service (SMS), and the like.

The memory 1320 may be used to store software programs and modules, and the processor 1380 executes various functional applications and data processing of the cellular phone by operating the software programs and modules stored in the memory 1320. The memory 1320 may mainly include a storage program area and a storage data area, wherein the storage program area may store an operating system, an application program required by at least one function (such as a sound playing function, an image playing function, etc.), and the like; the storage data area may store data (such as audio data, a phonebook, etc.) created according to the use of the cellular phone, and the like. Further, the memory 1320 may include high speed random access memory and may also include non-volatile memory, such as at least one magnetic disk storage device, flash memory device, or other volatile solid state storage device.

The input unit 1330 may be used to receive input numeric or character information and generate key signal inputs related to user settings and function control of the cellular phone. Specifically, the input unit 1330 may include a touch panel 1331 and other input devices 1332. Touch panel 1331, also referred to as a touch screen, can collect touch operations by a user (e.g., operations by a user on or near touch panel 1331 using any suitable object or accessory such as a finger, a stylus, etc.) and drive the corresponding connection device according to a preset program. Alternatively, the touch panel 1331 may include two portions of a touch detection device and a touch controller. The touch detection device detects the touch direction of a user, detects a signal brought by touch operation and transmits the signal to the touch controller; the touch controller receives touch information from the touch sensing device, converts the touch information into touch point coordinates, and sends the touch point coordinates to the processor 1380, where the touch controller can receive and execute commands sent by the processor 1380. In addition, the touch panel 1331 may be implemented by various types, such as a resistive type, a capacitive type, an infrared ray, and a surface acoustic wave. The input unit 1330 may include other input devices 1332 in addition to the touch panel 1331. In particular, other input devices 1332 may include, but are not limited to, one or more of a physical keyboard, function keys (such as volume control keys, switch keys, etc.), a trackball, a mouse, a joystick, and the like.

The Display unit 1340 may include a Display panel 1341, and optionally, the Display panel 1341 may be configured in the form of a Liquid Crystal Display (LCD), an Organic Light-Emitting Diode (OLED), or the like. Further, touch panel 1331 can overlay display panel 1341, and when touch panel 1331 detects a touch operation on or near touch panel 1331, processor 1380 can be configured to determine the type of touch event, and processor 1380 can then provide a corresponding visual output on display panel 1341 based on the type of touch event. Although in fig. 13, the touch panel 1331 and the display panel 1341 are two independent components to implement the input and output functions of the mobile phone, in some embodiments, the touch panel 1331 and the display panel 1341 may be integrated to implement the input and output functions of the mobile phone.

The handset may also include at least one sensor 1350, such as light sensors, motion sensors, and other sensors. Specifically, the light sensor may include an ambient light sensor that adjusts the brightness of the display panel 1341 according to the brightness of ambient light, and a proximity sensor that turns off the display panel 1341 and/or the backlight when the mobile phone is moved to the ear. As one of the motion sensors, the accelerometer sensor can detect the magnitude of acceleration in each direction (generally, three axes), can detect the magnitude and direction of gravity when stationary, and can be used for applications of recognizing the posture of a mobile phone (such as horizontal and vertical screen switching, related games, magnetometer posture calibration), vibration recognition related functions (such as pedometer and tapping), and the like; as for other sensors such as a gyroscope, a barometer, a hygrometer, a thermometer, and an infrared sensor, which can be configured on the mobile phone, further description is omitted here.

The audio circuit 1360 may transmit the electrical signal converted from the received audio data to the speaker 1361, and the electrical signal is converted into a sound signal by the speaker 1361 and output; on the other hand, the microphone 1362 converts the collected sound signal into an electric signal, converts the electric signal into audio data after being received by the audio circuit 1360, and then processes the audio data by the audio data output processor 1380, and then sends the audio data to, for example, another cellular phone via the RF circuit 1310, or outputs the audio data to the memory 1320 for further processing.

WiFi belongs to short-distance wireless transmission technology, and the mobile phone can help a user to receive and send e-mails, browse webpages, access streaming media and the like through the WiFi module 1370, and provides wireless broadband internet access for the user. Although fig. 13 shows the WiFi module 1370, it is understood that it does not belong to the essential constitution of the handset, and may be omitted entirely as needed within the scope not changing the essence of the invention.

The processor 1380 is a control center of the mobile phone, connects various parts of the entire mobile phone using various interfaces and lines, and performs various functions of the mobile phone and processes data by operating or executing software programs and/or modules stored in the memory 1320 and calling data stored in the memory 1320, thereby integrally monitoring the mobile phone. Optionally, processor 1380 may include one or more processing units; preferably, the processor 1380 may integrate an application processor, which handles primarily operating systems, user interfaces, application programs, etc., and a modem processor, which handles primarily wireless communications. It will be appreciated that the modem processor described above may not be integrated within processor 1380.

The handset also includes a power supply 1390 (e.g., a battery) to supply power to the various components, which may preferably be logically coupled to the processor 1380 via a power management system to manage charging, discharging, and power consumption management functions via the power management system.
