Background

Currently, the third Generation Partnership Project (3rd Generation Partnership Project, 3GPP) is researching Non-Terrestrial communication Network (NTN) technology, and the NTN generally provides communication services to Terrestrial users by using satellite communication.

Detailed Description

In order to make the objects, technical solutions and advantages of the present application more clearly understood, the present application is further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the present application and are not intended to limit the present application.

Some background related knowledge related to the embodiments of the present application is described below.

NTN related background

Currently, 3GPP is researching NTN technology, and the NTN generally provides communication service to terrestrial users by using satellite communication. Satellite communications have many unique advantages over terrestrial cellular communications. First, satellite communication is not limited by user regions, for example, general terrestrial communication cannot cover regions where communication equipment cannot be set up, such as oceans, mountains, deserts, and the like, or where communication coverage is not performed due to sparse population, and for satellite communication, since one satellite can cover a large ground and the satellite can orbit around the earth, theoretically every corner on the earth can be covered by satellite communication. Second, satellite communications have great social value. Satellite communication can be covered in remote mountainous areas, poor and laggard countries or areas with lower cost, so that people in the areas can enjoy advanced voice communication and mobile internet technology, the digital gap between the areas is favorably reduced and developed, and the development of the areas is promoted. Thirdly, the satellite communication distance is long, the communication distance is increased, and the communication cost is not obviously increased; and finally, the satellite communication has high stability and is not limited by natural disasters.

Communication satellites are classified into Low-Earth Orbit (LEO) satellites, Medium-Earth Orbit (MEO) satellites, geosynchronous Orbit (GEO) satellites, High-elliptic Orbit (HEO) satellites, and the like according to the difference in orbital height. The main studies at the present stage are LEO and GEO.

1.LEO

The height range of the low-orbit satellite is 500 km-1500 km, and the corresponding orbit period is about 1.5 hours-2 hours. The signal propagation delay for inter-user single-hop communications is typically less than 20 ms. Maximum satellite visibility time 20 minutes. The signal propagation distance is short, the link loss is less, and the requirement on the transmitting power of the user terminal is not high.

2.GEO

A geosynchronous orbit satellite, with an orbital altitude of 35786km, has a period of 24 hours of rotation around the earth. The signal propagation delay for inter-user single-hop communications is typically 250 ms.

In order to ensure the coverage of the satellite and improve the system capacity of the whole satellite communication system, the satellite adopts multiple beams to cover the ground, and one satellite can form dozens of or even hundreds of beams to cover the ground; one satellite beam may cover a ground area several tens to hundreds of kilometers in diameter.

NR HARQ mechanism

NR has a two-level retransmission mechanism: a HARQ mechanism of a Medium Access Control (MAC) layer and a HARQ mechanism of a Radio Link Control (RLC) layer. Retransmission of lost or erroneous data is mainly handled by the HARQ mechanism of the MAC layer and is supplemented by the retransmission function of the RLC layer. The HARQ mechanism of the MAC layer can provide fast retransmission, and the ARQ mechanism of the RLC layer can provide reliable data transmission.

HARQ uses a Stop-and-Wait Protocol (Stop-and-Wait Protocol) to transmit data. In the stop-wait protocol, after the sender sends a TB, the sender stops waiting for an acknowledgement. Thus, the sender may stop waiting for an acknowledgement after each transmission, resulting in low user throughput. Therefore, NR uses a plurality of parallel HARQ processes, and when one HARQ process is waiting for acknowledgement information, the transmitting end can continue to transmit data using another HARQ process. These HARQ processes together constitute a HARQ entity that incorporates a stop-and-wait protocol, allowing for continuous transmission of data. HARQ has a difference between uplink HARQ and downlink HARQ. The uplink HARQ is used for uplink data transmission, the downlink HARQ is used for downlink data transmission, and the uplink HARQ and the downlink HARQ are independent.

CG/SPS

In order to better serve periodic traffic, a concept of pre-Configured resources is introduced, and downlink is called Semi-Persistent Scheduling (SPS) and uplink is called Configured Grant (CG).

For each SPS configuration, the network configures a limited number of downlink HARQ processes for the SPS configuration, and the network uses the downlink HARQ processes to perform downlink transmission on SPS resources in a polling mode.

The SPS adopts a two-step resource configuration mode: firstly, configuring transmission resources and transmission parameters including the period of time domain resources, the number of HARQ processes and the like by a network RRC; then, a Physical Downlink Control Channel (PDCCH) scrambled by using a configuration Scheduling radio network temporary identifier (CS-RNTI) activates SPS-based Physical Downlink Shared Channel (PDSCH) transmission, and simultaneously configures other transmission resources and transmission parameters including time domain resources, frequency domain resources, MCS, and the like. When receiving the RRC configuration parameter, the UE cannot immediately use the resource and parameter configured by the RRC configuration parameter to receive the PDSCH, and must wait for receiving corresponding PDCCH activation and configuring other resources and parameters to receive the PDSCH.

Based on the current specification of the NR protocol, the terminal has a respective HARQ entity for each serving cell. Each HARQ entity maintains a set of parallel downlink HARQ processes and a set of parallel uplink HARQ processes. Currently, each uplink and downlink carrier supports 16 HARQ processes at maximum. The base station may indicate the maximum number of HARQ processes to the UE through RRC signaling semi-static configuration according to the network deployment situation. If the network does not provide corresponding configuration parameters, the downlink default HARQ process number is 8, and the maximum HARQ process number supported by each uplink carrier is always 16. Each HARQ process corresponds to a HARQ process Identification (ID). For downlink, a Broadcast Control Channel (BCCH) uses a dedicated Broadcast HARQ process. For uplink, Msg3 transmission in the random procedure uses HARQ ID 0.

For a terminal which does not support downlink space division multiplexing, each downlink HARQ process can only process 1 TB simultaneously; for a terminal supporting downlink space division multiplexing, each downlink HARQ process may process 1 or 2 TBs simultaneously. Each uplink HARQ process of the terminal processes 1 TB simultaneously.

HARQ is classified into two types, synchronous and asynchronous, in the time domain, and non-adaptive and adaptive, in the frequency domain. The uplink and the downlink of NR use an asynchronous adaptive HARQ mechanism. Asynchronous HARQ, i.e. retransmission, can occur at any time, and the time interval between the retransmission of the same TB and the last transmission is not fixed. The adaptive HARQ may change the frequency domain resource and the Modulation and Coding Scheme (MCS) used for the retransmission.

For each CG configuration, the network configures a limited number of uplink HARQ process numbers for the CG configuration, and the UE uses these uplink HARQ processes to perform uplink transmission on the CG resources in a polling manner.

NR supports two types of uplink unlicensed transmissions:

1. physical Uplink Shared Channel (PUSCH) transmission based on first Type of configuration grant (configured grant Type 1)

And configuring all transmission resources and transmission parameters including time domain resources, frequency domain resources, time domain resource periods, MCS, repetition times, frequency hopping, HARQ process number and the like by the network RRC. After receiving the RRC configuration, the terminal can immediately use the configured transmission parameters to perform PUSCH transmission on the configured time-frequency resources.

2. PUSCH TRANSMISSION BASED ON CONFIGURED Grant TYPE2 OF THE SECOND TYPE

A two-step resource allocation mode is adopted: firstly, configuring transmission resources and transmission parameters including the period, the repetition times, the frequency hopping, the HARQ process number and the like of time domain resources by a network RRC; and then activating a second type of PUSCH transmission based on the configuration authorization by the PDCCH scrambled by the CS-RNTI, and simultaneously configuring other transmission resources and transmission parameters including time domain resources, frequency domain resources, MCS and the like. When receiving the RRC configuration parameters, the UE cannot immediately use the resources and parameters configured by the configuration parameters to perform PUSCH transmission, and must wait for receiving corresponding PDCCH activation and configuring other resources and parameters to perform PUSCH transmission.

If the UE has no data to transmit on the PUSCH resources with the first and second type configuration authorization, the UE will not transmit anything on the resources with the configuration authorization.

Compared with the cellular network adopted by the traditional NR, the signal propagation delay between the UE and the satellite in the NTN is greatly increased, and in order to ensure the data transmission continuity without increasing the number of HARQ processes, the HARQ feedback function of the HARQ process may be closed in the current standardization process, and the following definite conclusion is formed:

1. the network device may configure whether to turn on the HARQ function.

2. If the HARQ function is off, the UE does not need to send HARQ feedback for the PDSCH to the network device.

3. In case of turning off HARQ feedback, in order to guarantee data transmission reliability, HARQ retransmission based on blind scheduling is still supported.

4. The configuration of the HARQ function on or off may be performed on a UE basis or on a HARQ process basis. For the UE-based configuration, HARQ functions of all HARQ processes configuring the UE are in an on or off state at the same time. For the configuration based on HARQ processes, that is, for multiple HARQ processes of one UE, the HARQ functions of one part of the HARQ processes may be configured to be in an on state, and the HARQ functions of another part of the HARQ processes may be configured to be in an off state.

5. The impact on other processes in both cases of HARQ on and HARQ off needs to be studied separately.

Based on the current standardization conclusion, under the condition of closing the HARQ feedback function of the HARQ process, in order to ensure the reliability of data transmission, the network can blindly schedule retransmission, namely for downlink transmission, the network can improve the robustness of the downlink transmission by scheduling the retransmission of the same downlink TB for multiple times under the condition of not having ACK/NACK feedback information from UE; for uplink transmission, before the network receives the PUSCH transmission from the UE, the network may schedule retransmission of the same uplink TB multiple times to improve robustness of uplink transmission. However, in this method for dynamically scheduling HARQ retransmission, the network device needs to send PDCCH signaling each time scheduling is performed, which brings a large amount of PDCCH signaling overhead.

The data transmission method provided by the application can solve the technical problem that the cost of the existing method for dynamically scheduling HARQ retransmission is large PDCCH signaling overhead. It should be noted that the data transmission method of the present application is not limited to solve the above technical problems, and may also be used to solve other technical problems, which is not limited in the present application.

Fig. 1 is a schematic view of an application scenario of a data transmission method according to an embodiment of the present application. As shown in fig. 1, the scenario includes a network device 104 and a terminal 102, where the terminal 102 and the network device 104 communicate over a network. The network device 104 may schedule resources, for example, the network device 104 configures transmission resources, and determine a bundling (bundling) relationship of data transmission resources using resource configuration information sent by the network device even when HARQ feedback functions of HARQ processes reserved for configuration authorization are all in an off state, and perform data transceiving on the data transmission resources having the same bundling relationship. The terminal 102 may be, but not limited to, various personal computers, notebook computers, smart phones, tablet computers, and portable wearable devices, and the network device 104 may be a base station, for example, implemented by an independent base station or a base station cluster formed by a plurality of base stations.

Fig. 2 is a flowchart of a data transmission method according to an embodiment. The embodiment relates to a specific implementation process that a terminal receives resource configuration information sent by network equipment, determines a binding relationship of data transmission resources according to the resource configuration information, and transmits and receives data in the data transmission resources with the same binding relationship. As shown in fig. 2, the method may include the steps of:

s201, the terminal determines the binding relation of the data transmission resources according to the resource configuration information of the data transmission resources sent by the network equipment.

The resource configuration information may include a Bandwidth part (BWP) configured for each serving cell of the terminal, and may also include a transmission resource configuration configured for each BWP, for example, the BWP may be a Downlink (DL) BWP or an uplink (Up Link, UL) BWP, each BWP may configure at least one transmission resource configuration, the at least one transmission resource configuration may be a downlink resource configuration or an uplink resource configuration, for example, the transmission resource configuration may be an SPS configuration or a CG configuration, the number of transmission resource configurations corresponding to each BWP is not limited, one transmission resource configuration may be configured for each BWP, or multiple transmission resource configurations may be configured for each BWP, for example, one SPS configuration is configured for each DL BWP of an Up cell of the terminal, and one CG configuration is configured for each BWP of a serving cell of the terminal, alternatively, configuring a plurality of SPS configurations for DL BWP of each serving cell of the terminal, and configuring a plurality of CG configurations for UP BWP of each serving cell of the terminal may be configured according to actual requirements, and the embodiment is not limited. The transmission resource configuration may include a resource period, a number of HARQ processes reserved for the transmission resource, an Identifier (ID) of the HARQ process, a HARQ feedback function state of the HARQ process, a number of retransmissions, and other parameters, which is not limited in this embodiment.

Optionally, the Resource configuration information may be carried in Radio Resource Control (RRC) signaling.

In this embodiment, after receiving the resource configuration information, the terminal may determine the bundling relationship of each data transmission resource, and perform data transceiving on the data transmission resources having the same bundling relationship. For example, the terminal may determine, according to the resource configuration information, a plurality of time-domain adjacent data transmission resources as a group of data transmission resources having the same binding relationship, starting from a specific data transmission resource. For example, 4 SPS resources are configured in the resource configuration information, and the terminal may bind 4 SPS resources adjacent to each other in the time domain into one group starting from the SPS resource with the earliest time domain, or, 3 CG resources are configured in the resource configuration information, and the terminal may bind 3 CG resources adjacent to each other in the time domain into one group starting from the CG resource with the earliest time domain. Different data transmission resources may have different bundling relationships, and the embodiments of the present application are not limited thereto.

S202, the terminal receives and transmits data through the data transmission resources with the same binding relation.

In this embodiment, after receiving the resource configuration information, the terminal determines the bundling relationship of each data transmission resource according to the resource configuration information, and performs data transceiving on the data transmission resources having the same bundling relationship, so that even if the HARQ feedback function of the HARQ process reserved for the data transmission resources is in an off state, data transceiving can be performed on the data transmission resources configured by the network device without dynamic scheduling of the network device. For example, if the network device configures a plurality of SPS resources for DL BWP of each serving cell of the terminal, the UE receives data on the SPS resources having the same bundling relationship. Alternatively, if the network device configures multiple CG resources for UL BWP of each serving cell of the terminal, the UE transmits data on a set of CG resources having the same bundling relationship.

In the data transmission method provided in the embodiment of the present application, the terminal determines the bundling relationship of the data transmission resources according to the resource configuration information of the data transmission resources sent by the network device, and transmits and receives data through the data transmission resources with the same bundling relationship, even if the HARQ feedback functions of the HARQ processes reserved for the data transmission resources are all in the off state, the terminal can transmit and receive data on the data transmission resources with the same bundling relationship after determining the bundling relationship of the data transmission resources through the resource configuration information sent by the network device, that is, repeatedly receive or transmit data on the data transmission resources with the same bundling relationship, ensure the reliability of data transmission when the HARQ feedback function is turned off, and directly use the data transmission resources with the same bundling relationship to receive or transmit data when the HARQ feedback function is turned off, the network equipment is not required to schedule data transmission resources through PDCCH signaling for many times, and a large amount of PDCCH signaling overhead is avoided.

In some scenarios, the data transmission resource needs to be activated to be used, for example, for the SPS resource or the CG resource using Type2, the terminal needs to be activated to implement data transceiving, and thus, in an embodiment, the data transmission resource is an activated data transmission resource, and the step S201 "the terminal determines the bundling relationship of the data transmission resource according to the resource configuration information of the data transmission resource," includes: and the terminal determines the binding relation of the data transmission resources according to the activated data transmission resources and the resource configuration information of the data transmission resources.

In this embodiment, the data transmission resource may be an activated data transmission resource, and the activation manner may be multiple, for example, after the network device sends the configuration information, the network device activates the data transmission resource through a PDCCH signaling, or the network device may determine the data transmission resource required by the terminal first, then activate the data transmission resource through the PDCCH signaling, and send the resource configuration information to the terminal, or the network device may activate the data transmission resource through the resource configuration information, or the network device may also activate the data transmission resource in another manner, which is not limited in this embodiment. The terminal repeatedly receives or sends data on the activated data transmission resource, so that the reliability of repeated data reception or sending is ensured.

In some scenarios, the network device may configure one data transmission resource for the BWP of each serving cell of the terminal, and in other scenarios, the network device may configure multiple transmission resources for the BWP of each serving cell of the terminal. The data transmission method provided by the embodiment of the present application is respectively described in detail through different scenarios.

Scene one: network equipment configures a plurality of SPS resources for a terminal

In one embodiment, the data transmission resources include N semi-persistent scheduling SPS resources, and the resource configuration information includes N SPS configurations, where N is an integer greater than 1.

In this embodiment, the network device may configure N SPS resources for each DL BWP of each serving cell of the terminal, and then the resource configuration information includes SPS configurations corresponding to the N SPS resources. Optionally, the value of N is determined according to the number of times that the network expects the same transport block TB to be repeatedly received using the transmission resource, that is, the value of N depends on the number of times that the network expects the same TB to be repeatedly received using the SPS resource. As shown in fig. 3, the network device configures SPS resources 1, SPS resources 2, SPS resources 3, and SPS resources 4 for the terminal, and may determine 4 SPS resources in the same SPS period as a group of SPS resources having the same bundling relationship, and the terminal may perform data reception through the group of SPS resources having the same bundling relationship.

Wherein each SPS configuration comprises: the method comprises the steps of (1) SPS resource period, hybrid automatic repeat request (HARQ) process number reserved for SPS resources, HARQ process identification, HARQ feedback function state information of the HARQ process and relation indication information configured by N SPS; the relation indication information is used for indicating a reference SPS configuration in the N SPS configurations and a relative time offset of each SPS configuration, wherein the relative time offset represents an offset of a starting position of a time domain resource of each SPS configuration relative to a starting position of a time domain resource of the reference SPS configuration. Optionally, the relative time offset is greater than or equal to 0, and the relative time offsets of the SPS configurations are different from each other.

In this embodiment, the N SPS configurations correspond to the same SPS resource period; reserving the same number of downlink HARQ processes for the N SPS configurations, setting the same downlink HARQ process ID for the N SPS configurations, and enabling the HARQ feedback functions of the downlink HARQ processes reserved for the SPS to be in a closed state; moreover, none of the N SPS configurations configures a corresponding PUCCH resource for feeding back ACK/NACK.

In this embodiment, the network device may indicate the reference SPS configuration in multiple ways, for example, a reference identifier is set on one SPS configuration of the N SPS configurations, and the SPS configuration with the reference identifier is the reference SPS configuration, or a relative time offset of the reference SPS configuration is set to 0, or a relative time offset is respectively configured for the remaining N-1 SPS configurations of the N SPS configurations, and the SPS configuration without the relative time offset is defaulted to be the reference SPS configuration, which is not limited in this embodiment.

Further, as shown in fig. 4, the step S201 "the terminal determines the bundling relationship of the data transmission resource according to the resource configuration information of the data transmission resource sent by the network device", includes:

s401, the terminal determines N SPS resources adjacent in a time domain as a group of SPS resources with the same binding relationship from the resources corresponding to the reference SPS configuration; the N time domain adjacent SPS resources correspond to the N SPS configurations, respectively.

In this embodiment, as shown in fig. 3, the network device configures 4 SPS resources for the terminal, determines, from left to right, the leftmost SPS resource 1 as a reference SPS resource, determines

adjacent SPS resources

1, 2, 3, and 4 as a set of SPS resources having the same bundling relationship, and determines N SPS resources located in the same set of bundling respectively correspond to N SPS configurations and are mapped to the same HARQ process number.

S402, the terminal associates the identifiers of the HARQ processes reserved for the N SPS resources to each group of SPS resources with the same binding relationship in sequence in a polling mode, and the identifiers of the HARQ processes corresponding to one group of SPS resources with the same binding relationship are the same.

In this embodiment, for each SPS resource of N SPS resources configured by the network device, a polling method is respectively adopted to sequentially associate downlink HARQ process numbers reserved for the SPS resources to each set of SPS resources having the same bundling relationship. As shown in fig. 3, the numbers of downlink HARQ processes reserved for SPS resources are HARQ #0 and HARQ #1, where N is 4, then HARQ #0 is associated with SPS configuration 1, SPS configuration 2, SPS configuration 3, and SPS configuration 4, and then HARQ #1 is associated with SPS configuration 1, SPS configuration 2, SPS configuration 3, and SPS configuration 4, so as to perform polling association.

According to the data transmission method provided by the embodiment of the application, a terminal determines N SPS resources adjacent in a time domain as a group of SPS resources with the same binding relationship from resources corresponding to a reference SPS configuration, the terminal adopts a polling mode to sequentially associate identifiers of HARQ processes reserved for the N SPS resources to each group of SPS resources with the same binding relationship, the N SPS resources adjacent in the time domain correspond to the N SPS configurations respectively, the identifiers of the HARQ processes corresponding to the group of SPS resources with the same binding relationship are the same, the terminal can repeatedly receive or send data on the group of transmission resources with the same binding relationship, and reliability of data repeated transmission is guaranteed.

Still further, step S202, "the terminal performs data transmission and reception through the data transmission resources having the same bundling relationship," includes: the terminal receives data through N SPS resources with the same binding relationship, and caches the data packet received M times by adopting the same HARQ process; m is less than or equal to N.

In this embodiment, the terminal may receive data on N SPS resources located in the same bundling, and cache the data packets received M times by using the same HARQ process, and at most cache the data packets received N times by using the same HARQ process. For N downlink receptions at the same bundling, the data received later does not cover the data received earlier. And the terminal combines and decodes the received multiple data packets. The same data packet is repeatedly received on a group of SPS resources with the same binding relationship, so that the terminal can accurately merge and decode the data packet, and the accuracy of data repeated transmission is ensured.

For SPS resources, after receiving resource configuration information sent by a network device, a terminal further needs to configure data transmission resources, and in one embodiment, the data transmission method further includes: a terminal receives an activation signaling sent by network equipment; the activation signaling is used for activating resources corresponding to the N SPS configurations.

Optionally, the activation signaling is signaling carried in a Physical Downlink Control Channel (PDCCH).

Optionally, one activation method is: the terminal receives an activation signaling sent by the network equipment; the activation signaling is used for indicating one time domain resource information and N frequency domain resource information, the time domain resource information is used for indicating the time domain resources corresponding to the reference SPS configuration, and the N frequency domain resource information is used for indicating the frequency domain resources corresponding to each SPS configuration.

In this embodiment, 1 PDCCH signaling may be used to activate N SPS resources, and 1 PDCCH signaling indicates 1 time domain resource information and N frequency domain resource information. The 1 time domain resource information is used for determining the time domain resources corresponding to the reference SPS configuration in the N SPS configurations, and the time domain resources corresponding to the rest N-1 SPS configurations in the N SPS configurations are obtained by deducing the relative time offset in the configuration information and the time domain resources corresponding to the reference SPS configuration. The N pieces of frequency domain resource information are respectively used for indicating frequency domain resources corresponding to the N pieces of SPS configuration. Because the time domain resources corresponding to the rest N-1 SPS configurations in the N SPS configurations are obtained by deducing the relative time offset in the configuration information and the time domain resources corresponding to the reference SPS configuration, one-to-one indication is not needed, and the signaling overhead can be reduced.

Optionally, another activation manner is: a terminal receives N activation signaling sent by network equipment; the N activation signalings are respectively used for indicating time domain resources and frequency domain resources corresponding to the SPS configurations. In this embodiment, N PDCCH signaling may be used to activate N SPS resources, respectively, which ensures the accuracy of resource activation.

Scene two, network equipment configures a plurality of CG resources for a terminal

In one embodiment, the data transmission resources include N semi-persistent scheduling CG resources, and the resource configuration information includes N CG configurations, N being an integer greater than 1.

In this embodiment, the network device may configure N CG resources for each ul bwp of each serving cell of the terminal, and the resource configuration information includes CG configurations corresponding to the N CG resources. Optionally, the value of N is determined according to the number of times that the network expects the same transport block TB to use the transport resource for repeated transmission, that is, the value of N depends on the number of times that the network expects the same TB to use the CG resource for repeated transmission.

In this embodiment, the network device may indicate the reference CG configuration in a variety of ways, for example, a reference identifier is set on one CG configuration in the N CG configurations, and the CG configuration with the reference identifier is the reference CG configuration, or a relative time offset of the reference CG configuration is set to 0, or a relative time offset is respectively configured for the remaining N-1 CG configurations in the N CG configurations, and a CG configuration without a relative time offset is defaulted to be the reference CG configuration, and so on, which is not limited in this embodiment of the application.

Further, as shown in fig. 6, the step S201 "the terminal determines the bundling relationship of the data transmission resource according to the resource configuration information of the data transmission resource sent by the network device", includes:

s601, the terminal determines N CG resources adjacent in time domain as a group of CG resources with the same binding relationship from the corresponding resources configured by the reference CG; the N time-domain adjacent CG resources correspond to the N CG configurations, respectively.

In this embodiment, as shown in fig. 5, the network device configures 4 CG resources for the terminal, determines, from left to right, a leftmost CG resource 1 as a reference CG resource, determines adjacent CG resources 1, CG resource 2, CG resource 3, and CG resource 4 as a group of CG resources having the same bundling relationship, and determines that N CG resources located in the same group of bundling respectively correspond to N CG configurations and are mapped to the same HARQ process number.

S602, the terminal associates the identifiers of the HARQ processes reserved for the N CG resources to the CG resources with the same binding relationship in sequence in a polling mode, and the identifiers of the HARQ processes corresponding to the CG resources with the same binding relationship are the same.

In this embodiment, for each CG resource in N CG resources configured by the network device, a polling manner is respectively adopted to sequentially associate downlink HARQ process numbers reserved for the CG resources to each group of CG resources having the same bundling relationship. As shown in fig. 5, the numbers of downlink HARQ processes reserved for CG resources are HARQ #0 and HARQ #1, where N is 4, then HARQ #0 is associated with CG configuration 1, CG configuration 2, CG configuration 3, and CG configuration 4, and then HARQ #1 is associated with CG configuration 1, CG configuration 2, CG configuration 3, and CG configuration 4, so as to perform polling association.

In the data transmission method provided by the embodiment of the application, a terminal determines, from resources corresponding to reference CG configuration, N CG resources adjacent to each other in a time domain as a group of CG resources having the same binding relationship, and the terminal associates, in a polling manner, identifiers of HARQ processes reserved for the N CG resources sequentially to the groups of CG resources having the same binding relationship, where the N CG resources adjacent to each other in the time domain correspond to the N CG configurations, and the identifiers of HARQ processes corresponding to the groups of CG resources having the same binding relationship are the same, and the terminal may repeatedly receive or transmit data on a group of transmission resources having the same binding relationship, thereby ensuring reliability of data repeated transmission.

Still further, step S202, "the terminal performs data transmission and reception through the data transmission resources having the same bundling relationship," includes: and the terminal transmits data through the N CG resources with the same binding relationship.

In this embodiment, the terminal may receive data on N CG resources located in the same bundling, and cache the data packets received M times by using the same HARQ process, and cache the data packets received N times by using the same HARQ process at most. For N downlink receptions at the same bundling, the data received later does not cover the data received earlier. And the terminal combines and decodes the received multiple data packets. The same data packet is repeatedly received on a group of CG resources with the same binding relationship, so that the terminal can accurately merge and decode the data packet, and the accuracy of data repeated transmission is ensured.

Optionally, the configuration information further includes transmission types of the N CG configurations, where the transmission types are PUSCH transmissions based on the first-type configuration grant or PUSCH transmissions based on the second-type configuration grant.

In this embodiment, if the N CG configurations are all type1CG resources, the N CG configurations further include CG time-frequency resource configurations, and after receiving configuration information sent by the network device, the terminal may determine that the CG resources perform data repeat sending.

In another embodiment, if the transmission types of the N CG configurations are all PUSCH transmissions based on the second type configuration grant, the method further includes: a terminal receives an activation signaling sent by network equipment; the activation signaling is used for activating resources corresponding to the N CG configurations.

Optionally, one activation method is: the terminal receives an activation signaling sent by the network equipment; the activation signaling is used for indicating one time domain resource information and N frequency domain resource information, the time domain resource information is used for indicating a time domain resource corresponding to the reference CG configuration, and the N frequency domain resource information is used for indicating a frequency domain resource corresponding to each CG configuration.

In this embodiment, 1 PDCCH signaling may be used to activate N CG resources, where 1 PDCCH signaling indicates 1 time domain resource information and N frequency domain resource information. The 1 piece of time domain resource information is used for determining the time domain resources corresponding to the reference CG configuration in the N CG configurations, and the time domain resources corresponding to the rest N-1 CG configurations in the N CG configurations are obtained by deducing the relative time offset in the configuration information and the time domain resources corresponding to the reference CG configuration. The N pieces of frequency domain resource information are respectively used for indicating frequency domain resources corresponding to the N pieces of CG configurations. Because the time domain resources corresponding to the rest N-1 CG configurations in the N CG configurations are obtained by deducing the relative time offset in the configuration information and the time domain resources corresponding to the reference CG configuration, one-to-one indication is not needed, and the signaling overhead can be reduced.

Optionally, another activation manner is: a terminal receives N activation signaling sent by network equipment; the N activation signaling are respectively used for indicating the time domain resource and the frequency domain resource corresponding to each CG configuration. In this embodiment, N PDCCH signaling may be used to activate N CG resources, respectively, so as to ensure the accuracy of resource activation.

In this embodiment, as shown in fig. 8, the terminal may receive data on 4 SPS resources located in the same bundling, and buffer data packets received at most 4 times by using the same HARQ process. For 4 downlink receptions at the same bundling, the data received later does not cover the data received earlier. And the terminal combines and decodes the received multiple data packets. The same data packet is repeatedly received on a group of SPS resources with the same binding relationship, so that the terminal can accurately merge and decode the data packet, and the accuracy of data repeated transmission is ensured.

As shown in fig. 10, the HARQ processes reserved for CG resources are denoted by HARQ #0 and HARQ #1, and polling associates HARQ #0 and HARQ #1 to each set of CG resources.

In the data transmission method provided by the embodiment of the application, starting from a first CG resource corresponding to CG configuration, N CG resources with continuous time domains are determined as a group of CG resources with the same binding relationship; the identifications of the HARQ processes corresponding to the group of bound CG resources are the same; and the identifier of the HARQ process reserved for the CG resource is sequentially associated to each group of the bound CG resources in a polling mode, and the terminal can repeatedly send data on the group of the bound CG resources, so that the reliability of data repeated transmission is ensured.

The embodiment relates to a specific implementation process that network equipment sends resource configuration information of data transmission resources to a terminal and performs data transceiving through the data transmission resources which are determined by the terminal and have the same binding relationship. As shown in fig. 11, the method may include the steps of:

s1101, the network equipment sends resource configuration information of data transmission resources to the terminal.

For example, the terminal may determine, according to the resource configuration information, a plurality of time-domain adjacent data transmission resources as a group of data transmission resources having the same binding relationship, starting from a specific data transmission resource. For example, 4 SPS resources are configured in the resource configuration information, and the terminal may bind 4 SPS resources adjacent to each other in the time domain into one group starting from the SPS resource with the earliest time domain, or, 3 CG resources are configured in the resource configuration information, and the terminal may bind 3 CG resources adjacent to each other in the time domain into one group starting from the CG resource with the earliest time domain.

For example, if the network device configures a plurality of SPS resources for the DLBWP of each serving cell of the terminal, the UE receives data on the SPS resources having the same bundling relationship, and the network device also transmits data on the SPS resources having the same bundling relationship. Alternatively, if the network device configures multiple CG resources for UL BWP of each serving cell of the terminal, the UE transmits data on a set of CG resources having the same bundling relationship, and the network device also receives data on the CG resources having the same bundling relationship.
