Description

Indication method, receiving method, terminal and network equipment of uplink control information

Technical Field

The present invention relates to the field of communications technologies, and in particular, to an indication method, a receiving method, a terminal, and a network device for uplink control information.

Background

Generally, the base station and the terminal understand how many physical resources are occupied for how many bits of Uplink Control Information (UCI) to be transmitted in Uplink, and the understanding of the two is consistent. This is determined either by base station scheduling or implicitly by the protocol according to some rules.

However, in some scenarios, for example, under a New Radio (NR) unlicensed (NR-U) technology deployed in an unlicensed frequency band in the future, a terminal determines how many bits of Hybrid Automatic Repeat request acknowledgement (HARQ-ACK) need to be fed back in an uplink by itself (i.e., ACK/NACK, note that the HARQ-ACK belongs to a part of the UCI), and at this time, the base station cannot know the number of HARQ-ACK bits that need to be fed back in the uplink. This may result in that the reception of the base station cannot correctly receive the content of the UCI and/or UL-SCH portion in the Physical Uplink Shared Channel (PUSCH) due to the inability to determine the number of bits or resources of the UCI portion.

The embodiment of the invention provides an indication method, a receiving method, a terminal and network equipment of uplink control information, and aims to solve the problems that when the terminal determines the number of bits of uplink control information needing to be fed back in an uplink mode by itself, a base station cannot acquire specific information of the uplink control information needing to be fed back in the uplink mode, so that the base station cannot accurately receive the uplink control information, and the reliability of network communication cannot be guaranteed.

In making the description of the embodiments of the present invention, some concepts used in the following description will be explained first.

(1) Physical Uplink Control Channel (PUCCH)

Compared with the previous mobile communication systems, future mobile communication systems need to adapt to more diversified scenes and service requirements. The main scenarios of the New Radio (NR) include: enhanced mobile broadband (eMBB), ultra-high Reliable and Low Latency Communications (URLLC), and large-scale internet of things (mMTC), which provide requirements for a system such as high reliability, low Latency, large bandwidth, wide coverage, and the like. In order to meet different services with different requirements and different application scenarios, NR introduces PUCCHs with different lengths, including: short PUCCH (1/2 Orthogonal Frequency Division Multiplexing (OFDM) symbols) and long PUCCH (4-14 OFDM symbols). And meanwhile, according to the size of Uplink Control Information (UCI) payload (payload) carried by the PUCCH, the Uplink Control Information (UCI) is divided into short/long PUCCH up to 2-bit UCI (with up to 2-bit UCI) and short/long PUCCH redundant 2-bit UCI (with more than 2-bit UCI). The long PUCCH larger than 2 bits is divided into a case of supporting multi-user multiplexing and a case of not supporting multi-user multiplexing.

Table 1 is a definition of PUCCH in 5 different formats. Wherein, PUCCH format 0 can transmit short/long PUCCH with at most 2 bits, format 1 can only be used to transmit Hybrid Automatic Repeat request acknowledgement (HARQ-ACK) with scheduling request (scheduling request, SR), one PUCCH only occupies one Physical Resource Block (PRB), format 2/3/4 can transmit UCI with more than 2 bits (including HARQ-ACK, channel State Information (CSI), and SR), where format 2 is short PUCCH occupies time domain 1, 2 OFDM symbols, and frequency domain can be 1 to multiple PRBs; the format 3/4 is that long PUCCH occupies 4-14 OFDM symbols in time domain, the format 3 frequency domain can be one or more PRBs and does not support multi-user multiplexing, the format 3 frequency domain only has 1 PRB and supports 2/4 users to multiplex on the same time-frequency resource.

Table 1 PUCCH format

(2)UCI

The UCI is a general term of uplink control information and comprises HARQ-ACK, SR and CSI.

Wherein, HARQ-ACK is feedback of User Equipment (UE) to downlink transmission, and when a data packet arrives at a receiving end, error detection is performed on the data packet, and if the data packet is received correctly, an Acknowledgement (ACK) signal is returned, and if the data packet is received incorrectly, a non-acknowledgement (NACK) signal is returned. HARQ-ACK is transmitted on PUCCH when the UE has no UL-SCH resources and on UL-SCH when there are UL-SCH resources.

SR is for requesting UL-SCH resources to the base station when the UE has no UL-SCH resources, and can only be transmitted on PUCCH since SR is transmitted only in the absence of UL-SCH. The periodicity of the system configuration is used for transmitting the resource of the SR PUCCH. If the HARQ-ACK and the SR need to be transmitted simultaneously at the same time, the UE may transmit the HARQ-ACK and the SR together.

The CSI includes a Channel Quality Indicator (CQI)/Precoding Matrix Indicator (PMI)/Rank Indicator (RI), is a report of downlink state information by the UE, and may be divided into periodic CSI (P-CSI), aperiodic CSI (a-CSI), and Semi-static CSI (SP-CSI) according to a transmission manner. The P-CSI is CSI configured by a higher layer and sent according to a certain period, and is transmitted on a PUCCH configured by the higher layer when no PUSCH is scheduled, and is transmitted on a scheduled PUSCH when a PUSCH is scheduled and the PUCCH and a Physical Uplink Shared Channel (PUSCH) cannot be simultaneously transmitted. For A-CSI, a base station dynamically triggers through downlink signaling and sends on a scheduled PUSCH resource, and the triggering is carried out once. For the SP-CSI, the SP-CSI is triggered by Downlink signaling and is sent multiple times according to a certain period, if the base station is triggered by a Medium Access Control Element (MAC CE), the SP-CSI is sent on a PUCCH resource, and if the SP-CSI is triggered by Downlink Control Information (DCI), the SP-CSI is sent on a PUSCH.

HARQ-ACK, SR and CSI (P-CSI and SP-CSI) can be transmitted on PUCCH, wherein resources of SR and CSI are periodicity of system configuration, HARQ-ACK is feedback of downlink transmission and is determined according to actual downlink transmission, and PUCCH resources are dynamically determined according to RRC configuration and downlink scheduling. Since the CSI and SR are transmitted periodically, there may be a collision with the dynamically scheduled HARQ-ACK, i.e. they need to be transmitted at the same or partially overlapping times.

(3)DCI

The DCI is carried by the PDCCH, and the base station issues downlink control information to the UE. Used for indicating uplink and downlink resource allocation, HARQ information, power control and the like to the UE.

(4) Multiplexing UCI on PUSCH

In NR, when both UL-SCH and UCI need to be transmitted in uplink, the transmission is carried out on a PUSCH after the UCI and data are multiplexed. The following fields are introduced for indicating a weight of resource utilization between UCI and UL-SCH, etc. through semi-static signaling or in DCI. The DCI dynamic indication mode introduces the following fields in the DCI:

beta _ offset indicator, if the high layer parameter does not dynamically configure UCI on PUSCH, the indication is 0 bit, otherwise, the indication is 2bit defined by table 7.3.1.1.2-27.

The 2-bit beta _ offset field indicates 4 possible sets of beta _ offset values, each set containing the weight values for each part of the UCI, e.g., a set of HARQ-ACK, CSI part 1, CSI part 2, etc. For example, as shown in table 2:

table 2beta _offsetvalue and weight value correspondence for each part of UCI

Wherein, the specific values in the right column in the table are configured to the terminal according to the signaling of Radio Resource Control (RRC).

The network supports the use of beta _ offset in the following way:

dynamic beta _ offset: namely, the high layer parameter dynamically configures the UCI (high layer parameter dynamic in UCI-on-PUSCH is configured) on the PUSCH;

static beta _ offset: namely, the high layer parameter semi-statically configures the UCI (high layer parameter semi static in UCI-on-PUSCH is configured) on the PUSCH.

With dynamic beta _ offset, there will be 2 bits in the DCI signaling for L1 to indicate which set of weight values is used at the moment. When static beta _ offset is adopted, no extra bit is provided in the DCI signaling of L1 to indicate which set of weight values is adopted, and the terminal and the network adopt a set of weight values preconfigured in a higher layer signaling.

In order to solve the problem that when a terminal determines how many bits of uplink control information need to be fed back in an uplink manner, a base station cannot acquire specific information of the uplink control information needing to be fed back in the uplink manner, so that the base station cannot accurately receive the uplink control information, and the reliability of network communication cannot be guaranteed, embodiments of the present invention provide an indication method, a receiving method, a terminal, and a network device for uplink control information.

Specifically, as shown in fig. 2, fig. 2 is a flowchart illustrating a method for indicating uplink control information according to an embodiment of the present invention, where the method for indicating uplink control information is applied to a terminal, and includes:

step 201, sending indication information of uplink control information UCI to network equipment;

it should be noted that the indication information is used for indicating the status of UCI transmission by the terminal.

It should be noted that the embodiment of the present invention is mainly applied to a situation that a terminal determines how many bits of UCI need to be fed back in an uplink by itself, and before sending UCI, indication information of UCI is sent to a network device, so that the network device can know a state of transmitting UCI (where the state of transmitting UCI, that is, a specific transmission condition of UCI, specifically includes whether UCI transmission is performed, a number of bits occupied by UCI, resources occupied by transmitting UCI, and the like), so as to accurately implement UCI reception.

Specifically, the indication information may include at least one of the following information:

a1, whether uplink transmission contains UCI transmission or not;

a2, the number of UCI bits contained in uplink transmission;

a3, a range of the number of UCI bits included in the uplink transmission.

It should be noted that, the UCI mainly includes: HARQ-ACK, SR and CSI, and for the network device, it may distinguish HARQ-ACK reception from SR and CSI reception, so optionally, at least one of the following information may also be included in the indication information:

a4, whether the uplink transmission contains the transmission of HARQ-ACK or not;

a5, the bit number of HARQ-ACK contained in uplink transmission;

and A6, the range of the number of bits of the HARQ-ACK included in the uplink transmission.

It should be further noted that, in order to make the network device explicitly know which resources to receive the UCI, optionally, the indication information may further include at least one of the following information:

a7, resource information used for UCI transmission in uplink transmission;

and A8, resource information used for HARQ-ACK transmission in uplink transmission.

Specifically, the resource information includes: the number of resources and/or the location of the resources.

Optionally, the indication information may further include:

a9, process identification of HARQ;

it should be noted that the process ID may be a process number of HARQ, for example, HARQ-ID.

In practical applications, the terminal may select one or more items of composition indication information from A1 to A9 to send to the network device.

It should be further noted that, the specific implementation manner of step 201 is:

sending the indication information to the network equipment through a first channel;

wherein the first channel comprises: physical Uplink Control Channel (PUCCH) or Physical Uplink Shared Channel (PUSCH).

Further, the terminal may map the indication information to a first time-frequency resource of the first channel through coding, and transmit the indication information to the network device through the first time-frequency resource (the first time-frequency resource refers to a resource other than a resource where a pilot is located); or

And the terminal carries the indication information in the uplink pilot frequency transmission of the first channel.

For example, as shown in fig. 3, the terminal maps the indication information to a specific time-frequency resource of uplink transmission through coding, where the indication information indicates a time-frequency position of UCI in the uplink transmission; alternatively, as shown in fig. 4, the terminal may transmit the indication information to the network device in the uplink pilot of the PUSCH, where the indication information indicates the resource location of the UCI in the uplink transmission.

After receiving the indication information, the network device acquires the specific situation of UCI transmission in the indication information, and correctly decodes through the indication information to acquire UCI, UL-SCH and the like in PUSCH or PUCCH.

It should be noted that, since the specific case of UCI transmission is determined by the indication information, the transmission position of UCI is dynamically variable.

It should be further noted that, in order to ensure that the terminal and the network device understand the indication information consistently, before sending the indication information of the uplink control information UCI to the network device, the terminal needs to obtain resource indication information occupied by the indication information.

Specifically, the resource indication information includes: the number of resources occupied by the indication information and/or the location of the resources occupied by the indication information.

It should be further noted that the resource indication information may be obtained from the network device side, or may be obtained by agreement.

When the terminal acquires the resource indication information from the network equipment side, the terminal can acquire the resource indication information by receiving a high-level signaling sent by the network equipment; or may be obtained by receiving Downlink Control Information (DCI) sent by the network device.

The embodiment of the invention can ensure that the network equipment can correctly decode the uplink data under the condition that the terminal autonomously changes the size of the UCI, thereby ensuring the reliability of network communication.

As shown in fig. 5, an embodiment of the present invention further provides a method for receiving uplink control information, which is applied to a network device, and includes:

step 501, receiving indication information of uplink control information UCI;

Step 502, receiving UCI according to the indication information;

optionally, the indication information includes at least one of the following information:

whether uplink transmission contains UCI transmission or not;

the number of bits of UCI included in the uplink transmission;

a range of the number of UCI bits included in the uplink transmission.

whether the uplink transmission contains the transmission of hybrid automatic repeat request acknowledgement (HARQ-ACK) or not;

the number of bits of HARQ-ACK contained in the uplink transmission;

range of the number of bits of HARQ-ACK included in the uplink transmission.

resource information for UCI transmission in uplink transmission;

resource information for HARQ-ACK transmission in uplink transmission.

Optionally, the indication information includes:

process identification of HARQ.

It should be noted that, the network device receives the indication information sent by the terminal through the PUCCH or the PUSCH, and the indication information may be mapped to the first time-frequency resource of the PUCCH or the PUSCH through coding, or directly carried on the uplink pilot of the PUCCH or the PUSCH.

According to the embodiment of the invention, the indication information of the UCI sent by the terminal is received before the UCI sent by the terminal is received, and the network equipment receives the UCI according to the indication information, so that the network equipment can be ensured to accurately receive the UCI, the network equipment and the terminal can be ensured to understand the UCI consistently, the accurate transmission of data is improved, and the reliability of network communication is ensured.

As shown in fig. 6, an embodiment of the present invention further provides a terminal 600, including:

a sending module 601, configured to send indication information of uplink control information UCI to a network device;

whether uplink transmission contains UCI transmission or not;

the number of bits of UCI included in the uplink transmission;

range of the number of UCI bits included in the uplink transmission.

whether the uplink transmission comprises the transmission of hybrid automatic repeat request acknowledgement HARQ-ACK or not;

the number of bits of HARQ-ACK contained in the uplink transmission;

range of the number of bits of HARQ-ACK included in the uplink transmission.

resource information for UCI transmission in uplink transmission;

resource information for HARQ-ACK transmission in uplink transmission.

Optionally, the indication information includes:

process identification of HARQ.

Further, the sending module 601 includes:

a sending unit, configured to send the indication information to the network device through a first channel;

wherein the first channel comprises: a physical uplink control channel PUCCH or a physical uplink shared channel PUSCH.

Specifically, the sending unit is configured to:

mapping the indication information to a first time-frequency resource of the first channel through coding, and transmitting the indication information to the network equipment through the first time-frequency resource; or

And carrying the indication information in the uplink pilot frequency transmission of the first channel.

Optionally, before the sending module 601 sends the indication information of the UCI to the network device, the terminal further includes:

the acquisition module is used for acquiring the resource indication information occupied by the indication information;

the resource indication information includes: the number of resources occupied by the indication information and/or the location of the resources occupied by the indication information.

Specifically, the resource indication information is obtained in at least one of the following manners:

obtaining by receiving a high-level signaling sent by the network device;

obtaining through agreement;

and obtaining the downlink control information DCI by receiving the downlink control information DCI sent by the network equipment.

It should be noted that, this terminal embodiment is a terminal corresponding to the above-mentioned indication method applied to the uplink control information at the terminal side, and all implementation manners of the above-mentioned embodiments are applied to this terminal embodiment, and the same technical effects as above can also be achieved.
