Description

Communication method and equipment Technical field

This application relates to the field of communication technology, and in particular to a communication party and equipment.

Background technique

For some services, the interval between two services is longer, and the communication data packets are smaller. In order to save energy and reduce signaling overhead, LTE release-16 decided to standardize the mechanism for transmitting data on pre-defined resources, that is, it does not require dynamic downlink control information (downlink control information, DCI) scheduling Communication, so it can also be called scheduling-free transmission. The uplink scheduling-free transmission process is as follows: when the terminal device has uplink data to send, the network device does not need to perform dynamic uplink scheduling on the terminal device, and the terminal device performs uplink transmission on the pre-configured transmission resource according to the predetermined transmission mode.

After the terminal device transmits a preconfigured uplink resource (PUR) transmission successfully or fails, the network device sends a successful reception response (ACK) or a failed transmission response (NACK) to the user. In addition, because the wireless channel environment changes dynamically with time, the transmission parameters pre-configured by the network device may not be applicable during PUR transmission, such as timing advance (TA), data repetition times, power control Information etc. Therefore, PUR configuration information also needs to be continuously updated.

Currently, network devices use user-specific downlink control information (DCI) to feed back to the user configuration update information such as a successful PUR transmission response or a PUR failure transmission response, TA and repetition times. However, since the number of bits occupied by ACK/NACK and updating configuration information is relatively small, there is a certain waste of resources in using user-specific DCI for feedback.

The network architecture and business scenarios described in the embodiments of this application are intended to more clearly illustrate the technical solutions of the embodiments of this application, and do not constitute a limitation on the technical solutions provided in the embodiments of this application. Those of ordinary skill in the art will know that with the network With the evolution of architecture and the emergence of new business scenarios, the technical solutions provided in the embodiments of the present application are equally applicable to similar technical problems. For some services, in order to reduce resource overhead, data transmission delay and energy saving, as shown in Figure 2, services can be transmitted on pre-defined resources, that is, no dynamic downlink control information (downlink control information, DCI) is required. ) Scheduling, users transmit signals on pre-configured resources. This kind of transmission is called configuration scheduled transmission, also called pre-configured resource transmission or pre-configured resource scheduling-free transmission or scheduling-free transmission. In particular, the pre-configured resources may be pre-configured uplink resources. The process of uplink scheduling-free transmission or preconfigured uplink resource transmission (PUR) is as follows: when a terminal device has uplink data to send, there is no need for the network device to perform dynamic uplink scheduling on the terminal device. The terminal device is pre-configured The uplink transmission is performed on the transmission resource according to the predetermined transmission mode.

After the terminal device transmits a preconfigured uplink resource transmission (PUR) successfully or fails, the network device sends a successful reception response (ACK) or a failed transmission response (NACK) to the user. In addition, during the pre-configuration transmission process, the user only has uplink signal transmission on the PUR resource, and the PUR configuration information of the user transmission signal is pre-configured by the base station instead of dynamically notified by the base station. However, the wireless channel environment changes dynamically with time. Therefore, the transmission parameters pre-configured by the network device may not be applicable during PUR transmission, such as timing advance (TA), data repetition times, power control information, etc. . Therefore, PUR configuration information also needs to be continuously updated.

Currently, network devices use user-specific downlink control information (DCI) to feed back to the user configuration update information such as a successful PUR transmission response or a PUR failure transmission response, TA and repetition times. However, since user-specific DCI usually occupies more than 30 bits, and the number of bits occupied by ACK/NACK and update configuration information is relatively small, usually less than 10 bits, there is a certain waste of resources in using user-specific DCI for feedback.

Based on this, the embodiments of the present application provide a communication method and device, which are used to solve the problem of waste of resources when the network device feeds back the PUR successful transmission response or the PUR failed transmission response to the user in the prior art and the PUR configuration update information. Among them, the method and the device are based on the same inventive concept. Because the method and the device have similar principles for solving the problem, the implementation of the device and the method can be referred to each other, and the repetitive parts will not be repeated.

The multiple mentioned in the embodiments of the present application refer to two or more.

It should be understood that in the description of this application, words such as "first" and "second" are only used for the purpose of distinguishing description, and cannot be understood as indicating or implying relative importance, nor can it be understood as indicating or implying order.

Refer to Fig. 3, which is a flowchart of a communication method provided by this application. The method can be applied to the communication system shown in FIG. 1, and the method includes:

S301: The first device determines first information corresponding to at least two second devices, where the first information includes configuration update information (or can also be referred to as parameter update information or configuration reconfiguration information or can also be referred to as parameter Reconfiguration information). Wherein, the configuration update information (or parameter update information or configuration reconfiguration information or parameter reconfiguration information) may be configuration update information of the pre-configured resource. The configuration update information includes update information of at least one of the following parameters (or, it can also be referred to as configuration update information including at least one of the following parameters): TA, data channel repetition times, control channel repetition times, deactivation information, paging ) Information, transport block size information, modulation and coding scheme, TA verification time. In addition, the configuration update information may also include power control information update information, or the configuration update information may also include power control information.

The first device may be a network device, and the second device may be a terminal device. Alternatively, the second device may be a network device, and the first device may be a terminal device. Alternatively, the first device may be a device with sending capability, and the second device may be a device with receiving capability.

In specific implementation, the configuration update information included in the first information may also be other parameters or configuration information of other parameters.

In addition, the first information may also include information indicating the transmission state of the pre-configured resource. The transmission state of the pre-configured resource includes one of the following states: successful transmission, unsuccessful transmission, scheduled retransmission, retransmission in pre-configured resources, transmission of a specific sequence , Initiate random access, early data transmission (EDT), and initiate non-competitive random access. Alternatively, it can also be understood that the first information may also indicate successful transmission or unsuccessful transmission or scheduling retransmission or retransmission in pre-configured resources or instructing transmission of a specific sequence or initiating random access or initiating EDT or initiating non-competition Random access.

In specific implementation, the first information may also only include information indicating the transmission status of the pre-configured resource.

As an exemplary illustration, the first information may only include paging information, and the paging message is used to indicate whether the user is paged, or the paging message may also be used to indicate whether to initiate random access or data transmission in advance. For example, 1 bit of the control information indicates the paging message, when the first information is in the first state (for example, the value of 1 bit is 1), it indicates that the second device is paged, and when the first information is in the second state (for example, , The value of this 1 bit is 0) indicating that the second device is not paged. Of course, when the bit value is 0, it indicates that the second device is paged, and when the bit value is 1, it indicates that the second device is not paged. In addition, the control information may indicate the paging message through multiple bits (such as 2 bits, etc.), which is not specifically limited here. The manner in which the control information can indicate the paging message through multiple bits is similar to the manner in which the control information can indicate the paging message through one bit, and the similarities will not be repeated.

In summary, the first information may include one or more of the following information: TA, data channel repetition times, control channel repetition times, deactivation information, paging information, power control information, transmission block size (TBS) ) Information, modulation and coding scheme (MCS), TA verification time, information indicating successful transmission, information indicating unsuccessful transmission, information indicating scheduling retransmission, indicating retransmission in pre-configured resources Information, information indicating the transmission of a specific sequence, information indicating the initiation of random access, information indicating the EDT, and information indicating the initiation of non-competitive random access.

In this embodiment of the present application, TA is the timing advance information used when the second device transmits uplink data in pre-configured resource transmission.

The number of repetitions of the data channel may be the number of repetitions of an uplink data channel (physical uplink shared channel, PUSCH) or the number of repetitions of a downlink data channel (physical downlink shared channel, PDSCH).

The control channel in the number of control channel repetitions includes physical downlink control channel (PDCCH) or machine type communication physical downlink control channel (machine type communication physical downlink control channel, MPDCCH) or enhanced physical downlink control channel (enhanced physical) downlink control channel, ePDCCH) or narrowband physical downlink control channel (narrowband physical downlink control channel, NPDCCH). It can also be other types of control channels, which are not specifically limited here.

The deactivation information may also be the deactivation information, which is used to indicate that the second device does not transmit information on the first resource or does not use the first resource to transmit uplink information. It can also be understood as deactivating or de-enabling the first resource, or indicating that the first resource is in a deactivated or de-enabled state. The exemplary first resource is a pre-configured resource.

The power control information may be a target amount or adjustment amount of power, or the size of a power ramping step. The target amount here means that the second device uses the power information as the transmission power to transmit information; the adjustment amount is to determine the transmission power based on the most recent transmission power and the adjustment amount, that is, add or subtract the adjustment on the basis of the most recent transmission power (For example, if the adjustment is negative, the adjustment is subtracted from the most recent transmission power. If the adjustment is positive, the adjustment is added to the most recent transmission power); It refers to the adjustment granularity (or unit) of the second device's power adjustment each time, and the second device adjusts the current transmission power according to the climbing steps and the most recent transmission power. This climbing step can also be understood as the amount of adjustment of the transmission power each time.

The TA verification time is the time for the second device to verify TA. For example, the first device may use the first information to instruct the second device to perform TA verification no earlier than x time units before the start position of the first resource, or the first device may use the first information to indicate that the second device is the earliest (or furthest) , Or the maximum) verification time is x time units before the start position of the first resource, and the time unit can be a subframe, frame, time slot, ms, symbol, s, or us, etc., and is not specifically limited. It can also be understood that the first device indicates the first time period through the first information, and the second device performs TA verification in the first time period, and the start time of the time period is x times before the start time of the first resource Unit, ending as y time units of the first resource, where x>y, where y can be equal to or greater than zero. In a specific implementation, the first device may indicate the verification time of the TA through other information independent of the first information, that is, the verification time of the TA may be sent separately.

In specific implementation, the first device may also send first indication information to the first device, where the first indication information is used to indicate the starting position of the user search space. Optionally, the first information activates or deactivates information. For example, when discontinuous transmission or skipping is enabled, the search space is in the first position, and when discontinuous transmission or skipping is disabled, the search space is in the second position. Further, when the search space is located at the first position, the control information may include PUR deactivation information. Among them, this control information may be user-specific control information, or may be user group control information. The second device can determine whether to use the first position or the second position in a predefined manner.

The information indicating the successful transmission can be the normal reception ACK (Acknowledgement). The information indicating the unsuccessful transmission may be NACK (Negative Acknowledgement) not normally received.

In some implementations, the first information may only include ACK, or the first information may only include NACK.

In other embodiments, when the second device transmits a specific sequence in the PUR, the first device may not feed back the ACK to the second device. That is, the first information includes information indicating transmission of a specific sequence, or, when the first information is used to indicate transmission of a specific sequence, the first information may not include ACK/NACK.

For the convenience of description, the following describes the embodiments of the present application by taking as an example the information indicating successful transmission is ACK and the information indicating unsuccessful transmission is NACK.

S302: The first device sends control information, where the control information carries first information of at least two second devices. Correspondingly, the second device receives the control information sent by the first device.

S303: The second device determines first information corresponding to the second device based on the control information.

Compared with the prior art using user-specific DCI to feed back ACK/NACK and update configuration information, in this embodiment of the application, the first device can feed back the first information to the second device through user group control information, so that it can be included in one message. Carrying the first information of multiple second devices can save network resources and reduce user power consumption.

As a possible implementation manner, if the first information includes configuration update information of the pre-configured resource and information indicating the transmission state of the pre-configured resource. Information 1 and information 2 of the same second device can be configured to be the same in the position of the control information. Take the control information carrying the first information of UE1 to UE4 as an example, as shown in Figure 4, where information 1-1, information 1-2, information 1-3, and information 1-4 are the configuration update information of the pre-configured resources of UE1 to UE4, respectively, and information 2-1, information 2-2, information 2-3, and information 2-4 are UE1 to UE4, respectively. UE4's information indicating the transmission status of the pre-configured resource.

Therefore, the configuration update information of the pre-configured resource of the second device and the information indicating the transmission state of the pre-configured resource can be configured to have the same index in the position of the control information, for example, information 1-1 and information 2-1 of UE1. The positions of are all positions with an index of 1. At this time, one message can be used for notification, which can save signaling resources.

Alternatively, the configuration update information of the pre-configured resource of the same second device and the information indicating the transmission state of the pre-configured resource can be configured to be different in the position of the control information. Take the control information carrying the first information of UE1 to UE4 as an example, for example, As shown in FIG. 5, information 1-1, information 1-2, information 1-3, and information 1-4 are configuration update information of the pre-configured resources of UE1 to UE4, respectively, which are located in the first 4 positions of the control information in sequence. Information 2-1, information 2-2, information 2-3, and information 2-4 are respectively the information indicating the transmission status of the pre-configured resources of UE1 to UE4, which are located in the last 4 positions of the control information in sequence.

Therefore, the positions of the configuration update information of the pre-configured resources of the second device and the information indicating the transmission status of the pre-configured resources can be configured to be different in the index of the position of the control information. For example, the positions of information 1-1 of UE1 are both The position of the index 1 and the position of the information 2-1 are the position of the index 5. In this case, the two pieces of information respectively indicate the position of the information 1-1 and the position of the information 2-1 of the UE1, thereby improving flexibility.

In a specific implementation, the position in the control information of the first information corresponding to the at least two second devices, such as an index (index) or a bit position, may be configured by the first device through high-layer signaling. Specifically, the first device may configure the position in the control information of the first information corresponding to at least two second devices in the following manner: For each second device, the first device sends second signaling to the second device, and The second signaling is used to indicate the index of the position in the control message of the first information corresponding to the second device. Correspondingly, the second device receives the second signaling sent by the first device, so as to determine the position in the control message corresponding to the first information of the second device according to the second signaling. Exemplarily, the second signaling may be a radio resource control (radio resource control, RRC) message or a media access control control element (media access control control element, MAC CE) message. Taking the schematic diagram shown in FIG. 4 as an example, the first device may configure the positions of the first information of UE1 to UE4 in the control information to positions with indexes 1, 2, 3, and 4 through an RRC message or a MAC CE message. Or, taking the schematic diagram shown in FIG. 5 as an example, the first device may configure UE1's pre-configured resource configuration update information through an RRC message or a MAC CE message. The position in the control information is the position with an index of 1, respectively, and configure UE1's The positions of the information indicating the transmission status of the pre-configured resources in the control information are positions with an index of 5 respectively.

Alternatively, the position in the control information of the first information corresponding to the at least two second devices, such as index or bit position, may be predefined. Therefore, the second device can use the predefined index as the index of the position in the control information corresponding to the first information by the second device. For example, taking the schematic diagram shown in FIG. 4 as an example, the index of the position of the first information of UE1 in the control information is 1. Taking the schematic diagram shown in FIG. 4 as an example, the index of the position in the control information of the configuration update information of the UE1's pre-configured resource is 1, and the index of the position in the control information of the information indicating the transmission status of the pre-configured resource is 5.

In some embodiments, when the first device sends control information, it may first determine the location index corresponding to the second device, carry the first information corresponding to the second device at the location corresponding to the index in the control information, and then send the Control information.

Specifically, if the configuration update information of the pre-configured resource and the information indicating the transmission status of the pre-configured resource of the same second device can be configured to be the same in the position of the control information, the first device can instruct the second device through a piece of second signaling. The position of the first information of the device in the control information. If the configuration update information of the pre-configured resource and the information indicating the transmission state of the pre-configured resource of the same second device can be configured to be different in the position of the control information, the first device can indicate the second device through two second signalings. The configuration update information of the pre-configured resource of the device is in the position of the control information, and the information indicating the transmission state of the pre-configured resource is in the position of the control information.

Correspondingly, when the second device determines the first information corresponding to the second device based on the control information, it can find the position corresponding to the index in the control information, and then obtain the first information at that position.

Specifically, if the configuration update information of the pre-configured resource of the same second device and the information indicating the transmission status of the pre-configured resource can be configured to be the same in the position of the control information, the second device can predefine an index, and then After the information is controlled, the first information is obtained at the corresponding position of the index. If the configuration update information of the pre-configured resource of the same second device and the information indicating the transmission status of the pre-configured resource can be configured to be different in the position of the control information, the second device can predefine two indexes, and after receiving the control After the information is obtained, the configuration update information of the pre-configured resource and the information indicating the transmission state of the pre-configured resource are respectively obtained at the corresponding positions of the two indexes.

As a possible implementation manner, for the update information of the first parameter in the configuration update information, the first parameter is one or more of the following parameters: TA, data channel repetition times, control channel repetition times, power control information, Transport block size information and modulation and coding schemes. The update information of the first parameter may be the target amount of the first parameter or the adjustment amount of the first parameter. Among them, the adjustment amount can be positive or negative.

Therefore, the second device can adjust the parameter value of the first parameter to the target value; or, the parameter value of the first parameter can be adjusted on the basis of the current parameter value.

In an exemplary description, the M bits of the control information are used to indicate the update information of the first parameter, wherein the m bits in the M bits are used to indicate the adjustment granularity of the update information, and the Mm bits in the M bits are used to indicate the first parameter. The target amount or adjustment amount of the parameter is the amount when the unit of adjustment granularity is used. M and m are integers greater than 0, and m is less than M. For example, assuming that the adjustment granularity of using m bits to indicate update information is 2, and the M-m bit indicating value (or value) is 5, the target amount or adjustment amount of the first parameter is 2×5=10.

Further, the second device may adjust the parameter value of the first parameter to the product of the adjustment granularity indicated by m bits and the number indicated by M-m bits. Alternatively, the second device may adjust the parameter value of the first parameter on the basis of the current parameter value by the product of the adjustment granularity indicated by m bits and the number indicated by M-m bits.

Exemplarily, the first parameter may specifically be power control information or data channel repetition times or control channel repetition times or TA.

Taking the first parameter as TA as an example, the control information can use 3 bits to indicate the adjustment amount of TA, where the high-order (or low-order) bit is used to indicate the adjustment granularity, for example, when the high-order bit is set to 0, the adjustment granularity is 2 ^k1 *16Ts, where T _s = 1/(15000×2048) second, when the high bit value is 1, it means that the adjustment granularity is 2 ^k2 *16Ts, where k1 and k2 can be positive or negative; the lower two digits Bits are expressed as the quantity when the granularity of adjustment is a unit; according to the formula: TA _new =TA _old +(PQ)*G, where TA _new and TA _old are the amounts after and before adjustment, respectively, and P and Q are predefined , G is the adjustment particle size; or the indicator is the first parameter, the TA adjustment amount is determined according to the first parameter and the particle size, such as according to the formula: TA _new =TA _old +(PQ)*G, where TA _new and TA _old are respectively After TA adjustment and before adjustment, P is determined according to the first parameter, Q is predefined, and G is the adjustment granularity.

For example, as shown in Figure 6, the 6 positions in the figure represent the 6 bits that carry the TA adjustment in the prior art, and the high 0 of the 3 bits of the TA adjustment represents the adjustment granularity corresponding to the low two of the 6 bits. It is 16Ts, and the lower two bits are 11, so the final TA adjustment amount is TA _new =TA _old +(3-1)*16Ts. Or, the high bit 1 indicates that the adjustment granularity corresponding to the high two bits of the six bits is 2 ⁴ *16Ts, and the low two bits are 11, so the final adjustment amount is TA _new =TA _old +(3-1)*2 ⁴ *16Ts .

Wherein, for example, the first set includes one or more values, the Mm bit in the M bits can indicate the adjustment amount or target value of the first parameter by indicating the index of the value in the first set, for example, the Mm bit indicates 3, then the first parameter The second device may determine the first set according to the m bits, and then determine the third value in the first set as the adjustment amount or target value of the first parameter according to the Mm bits.

Further, the first parameter may specifically be TBS or MCS. Among them, the m bits in the M bits are used to indicate that the target value or adjustment amount of TBS or MCS is in the first set, and the Mm bits in the M bits are used to indicate the adjustment amount or target value of TBS (or MCS) in the first set. .
