[0111] It should be noted that 5G NR (New Radio) defines user plane latency as: the time required to successfully transfer an application layer data packet and / or message from a layer 2 / 3 SDU (service Data Unit) ingress point to a layer 2 / 3 SDU egress point through the air interface resources in the uplink and downlink directions without being limited by DRX (Discontinuous Reception) at either the device or base station reception.

[0112] For URLLC (Ultra Reliable and Low Latency Communication) services, the target for user plane latency should be 0.5 ms for the uplink and 0.5 ms for the downlink. In addition, the latency should also be low enough if possible. For eMBB (enhanced mobile broadband) services, the target for user plane latency should be 4 ms for the uplink and 4 ms for the downlink.

[0113] If the uplink data is sent through a dynamically scheduled grant, the entire user plane latency of the pending uplink data includes the following parts: average SR (Scheduling Request) transmission latency, terminal sending SR, base station decoding SR, base station generating scheduling grant, base station sending scheduling grant, terminal processing latency (decoding the scheduled grant), terminal sending uplink data (multiplexing and assembling (LCP process) + sending data packets in the scheduling grant), base station receiving uplink data, and base station decoding uplink data.

[0114] To reduce latency, configured grant (CG) is supported in 5G system, including configured grant Type 1 and configured grant Type 2, which is configured according to terminal granularity, for example, periodic resources, and the terminal does not need to request a dynamic scheduling grant through SR, but can directly send uplink data on the configured grant. In order to support XR scenarios in 5G systems, configured grant supports multiple PUSCH (Physical Uplink Shared Channel) resources, and the terminal can send uplink data on multiple consecutive PUSCH resources / CG resources, and in order to improve the resource utilization of configured grant, the terminal can dynamically indicate the use and non-use of CG resources through "UTO-UCI" (uplink control information for unused transmission occasion indication information). For CG resources not used by the terminal, the network device can schedule other terminals based on implementation. The terminal can change the previously indicated "UTO-UCI" to indicate the use of CG to not use through subsequent "UTO-UCI", but if the CG has been indicated not to be used, it cannot be changed to be used. For the configured grant in the XR scenario, for the CG resource indicated by the terminal not to be used, if the network device does not schedule other terminals, this terminal also cannot use this CG resource, which will cause a certain degree of CG resource waste and reduce the utilization of resources.

[0115] In 6G communication, latency is a key indicator, and configured grant can continue to be applied to 6G systems. At the same time, considering improving the resource utilization of configured grant, a method of sharing configured grant can be considered. In some embodiments, the shared configured grant is a configured grant shared by multiple terminals, and the terminal can indicate through second information that the network device will use and / or will not use the CG resource, and when more than one terminal indicates to use the same CG resource, the network device is responsible for solving the conflict, for example, indicating which terminal can use the CG resource.

[0116] However, if the terminal has sent second information indicating that the CG resource will be used and / or will not be used, for the CG resource to be used, if the terminal does not receive first information indicating whether it is available from the network device, how the terminal determines whether the CG resource can be used has become a problem to be solved.

[0117] Based on this, the embodiment of the disclosure provides a communication method and device, which can solve the problem of how to determine whether the CG resource is available in the scenario of sharing the configured grant, thereby improving the resource utilization of the configured grant.

[0118] FIG. 2A is an interaction diagram of a communication method according to an embodiment of the disclosure. As shown in FIG. 2A, the embodiment of the disclosure relates to a communication method applicable to the communication system 100, and the method includes but is not limited to the following steps.

[0119] In step S2101, the network device 102 sends the first configuration information of the first configured grant to the terminal 101.

[0120] In some embodiments, the first configured grant is a shared configured grant. For example, whether the first configured grant is a shared configured grant can be determined by a first parameter associated with the first configured grant. For example, the first parameter can be agreed by a protocol, or the first parameter can be configured by the network device. For example, the network device sends the first parameter to the terminal 101, for example, the first parameter can be configured to the terminal 101 by the first configuration information, that is, the first configuration information includes the first parameter, for example, the first parameter can also be configured to the terminal 101 by other configuration information different from the first configuration information. For example, the first configuration information can be a high layer parameter (such as ConfiguredGrantConfig).

[0121] In one possible implementation, the first parameter has a first value (such as enabled), and the configuration of the first parameter indicates that the first configured grant is a shared configured grant, and the non-configuration of the first parameter indicates that the first configured grant is a non-shared configured grant. In another possible implementation, the first parameter has a first value (such as enabled), and the configuration of the first parameter indicates that the first configured grant is a non-shared configured grant, and the non-configuration of the first parameter indicates that the first configured grant is a shared configured grant. In another possible implementation, the first parameter indicates whether the first configured grant is a shared configured grant, the first parameter has a second value, indicating that the first configured grant is a shared configured grant, and the first parameter has a third value, indicating that the first configured grant is a non-shared configured grant. For example, the second value can be 1, and the third value can be 0; or the second value can be 0, and the third value can be 1; or the second value and the third value adopt other value modes, which are not limited in the disclosure. For example, the shared configured grant can mean that the configured grant can be shared among multiple terminals, the first configured grant is a shared configured grant, that is, the first configured grant can be shared among multiple terminals, and the terminal 101 belongs to the multiple terminals. The first configured grant is a non-shared configured grant, that is, the first configured grant is a configured grant dedicated to the terminal 101.

[0122] In some embodiments, the first configuration grant is associated with one or more CG resources, i.e., the first configuration grant indicates one or more CG resources. For example, the network device configures the first configuration grant, and the configured first configuration grant indicates one or more CG resources. Alternatively, the network device sends first configuration information of the first configuration grant to the terminal, and the terminal receives the first configuration information sent by the network device, and determines the one or more CG resources associated with the first configuration grant according to the first configuration information. In some embodiments, the first configuration information is used by the terminal 101 to determine whether a first CG resource can be used by the terminal 101, where the first CG resource belongs to the one or more CG resources, i.e., the first CG resource is a CG resource in the one or more CG resources indicated by the first configuration grant. In some embodiments, the first CG resource can be a CG resource that is not indicated by the network device 102 as available. In some embodiments, the first CG resource can be a CG resource to be used by the terminal 101, e.g., the terminal 101 reports the CG resource to be used by the terminal 101 to the network device 102 through second information. For example, the first CG resource is a CG resource reported by the terminal 101 to the network device 102 through second information, but the terminal 101 does not receive first information indicating whether the first CG resource is available to the terminal 101, and the transmission time of the first CG resource will arrive or has arrived. For example, the first CG resource can be a CG resource through which the terminal 101 sends second information.

[0123] In some embodiments, the first configuration grant can be a shared configuration grant, and can be shared among multiple terminals. A terminal 101 in the multiple terminals can indicate a CG resource to be used and / or not to be used to the network device through second information, and the CG resource to be used and / or not to be used can be a CG resource in the one or more CG resources associated with the first configuration grant. When two or more terminals in the multiple terminals indicate to use the same CG resource, the network device is responsible for solving the conflict, e.g., by indicating through first information which terminal can use the CG resource. For example, in the case where the terminal 101 does not receive first information indicating whether a CG resource is available from the network device 102, the terminal 101 can determine whether a certain CG resource (i.e., a first CG resource) associated with the first configuration grant can be used by the terminal 101. The certain CG resource associated with the first configuration grant can be understood as a certain CG resource in the one or more CG resources indicated by the first configuration grant.

[0124] It should be noted that the second information can be reported by the terminal 101 to the network device 102, and the second information can include CG resources to be used by the terminal 101 (i.e., CG resources to be used) and / or CG resources not to be used by the terminal 101 (i.e., CG resources not to be used), and the CG resources to be used and / or the CG resources not to be used are CG resources in the one or more CG resources associated with the first configured grant, and the first configured grant is a shared configured grant. For example, when the first configured grant is a shared configured grant, the terminal 101 can report the CG resources to be used and / or the CG resources not to be used to the network device 102 through the second information. For example, the second information can be sent through a PUSCH (Physical Uplink Shared Channel) or a PUCCH (Physical Uplink Control Channel). In a possible implementation, the terminal 101 sends a PUSCH to the network device 102 on a third CG resource, and the network device 102 receives the PUSCH sent by the terminal 101 on the third CG resource, and the PUSCH includes the second information, and the third CG resource is a CG resource associated with the first configured grant. In another possible implementation, the terminal 101 can send the second information through a PUCCH.

[0125] In some embodiments, the second information can include a first bitmap, and the first bitmap includes a first number of indication bits, and each indication bit corresponds to a CG resource, and an indication bit in the first bitmap is used to indicate that the corresponding CG resource is a CG resource to be used or a CG resource not to be used; wherein the indication bit in the first bitmap is a fourth value, and the fourth value is used to indicate that the corresponding CG resource is a CG resource to be used; and the indication bit in the first bitmap is a fifth value, and the fifth value is used to indicate that the corresponding CG resource is a CG resource not to be used. For example, the fourth value can be 1, and the fifth value can be 0; or the fourth value can be 0, and the fifth value can be 1; or the fourth value and the fifth value can adopt other values, which are not limited in the present disclosure. In some embodiments, the size of the first bitmap can be related to the number of CG resources, that is, the first number. That is, the terminal 101 determines the size of the first bitmap based on the number of CG resources. The number of CG resources can be determined based on the first parameter, or can be determined through the second configuration information described below. The size of the first bitmap can be less than the first number. For example, the network device 102 can configure the first number through RRC (Radio Resource Control) signaling.

[0126] In some embodiments, the CG resource corresponding to the first number of indication bits is a CG resource behind a third CG resource among the one or more CG resources (i.e., the one or more CG resources associated with the configured grant), and the third CG resource is the CG resource carrying the second information. For example, the CG resources indicated by the first number of indication bits are arranged in ascending order of the start time of the CG resources. In some embodiments, the first CG resource indicated by the first number of indication bits is an Mth CG resource behind the third CG resource among the one or more CG resources, where M is a positive integer. For example, the M can be a default value, such as 1, i.e., the first CG resource indicated by the first number of indication bits can be the first CG resource behind the third CG resource among the one or more CG resources. For example, the M can be configured by the network device.

[0127] It should be noted that in some embodiments, the first information can be used to indicate whether the CG resource to be used can be used by the terminal after the network device receives the second information sent by the terminal to indicate that the CG resource to be used and / or the CG resource not to be used. In some embodiments, the network device can indicate the available CG resource to the terminal by the first information after receiving the second information sent by the terminal. In some embodiments, the first information can be used to indicate the available CG resource of one or more terminals, and the terminal 101 belongs to the one or more terminals. For example, the terminal 101 determines that the configured grant is a shared configured grant, the configured grant is associated with one or more CG resources, the configured grant is shared between the one or more terminals, and the terminal 101 indicates the CG resource not to be used and / or the CG resource to be used from the one or more CG resources to the network device 102 by the first information. The network device 102 can indicate the available CG resource to the terminal by the first information. For example, the network device 102 can receive the first information sent by one or more terminals, and each terminal sends the first information to indicate the CG resource not to be used and / or the CG resource to be used by the corresponding terminal. When two or more terminals indicate the same CG resource to be used, the network device 102 can be responsible for solving the conflict, for example, indicating which terminal uses the CG resource, and the terminal 101 is one of the one or more terminals. Alternatively, when the network device 102 receives the first information sent by one or more terminals, and each terminal sends the first information to indicate the CG resource not to be used and / or the CG resource to be used by the corresponding terminal, when two or more terminals indicate the same CG resource to be used, and the terminal 101 belongs to the two or more terminals, the network device 102 can send the first information to the two or more terminals, and the first information sent by the network device to the two or more terminals is the same information, indicating which terminal can use the CG resource. For example, when the CG resource to be used indicated by the one or more terminals is not the same, i.e., the CG resource to be used by the one or more terminals is not the same CG resource, the network device 102 can also send the first information to the one or more terminals respectively, indicating the available CG resource of the corresponding terminal.

[0128] Exemplarily, the first information can be a PDCCH (Physical Downlink Control Channel) scrambled by a first RNTI. Exemplarily, the first RNTI can be a newly defined RNTI. Exemplarily, the first RNTI can be a group-based RNTI, for example, a group-common RNTI. That is, the first RNTI can be a scrambling code that can be descrambled by a UE-group. The network device 102 can indicate, through the PDCCH scrambled by the first RNTI, one or more CG resources that can be respectively used by one or more terminals.

[0129] In some embodiments, the first information can be used to indicate the CG resources available to the terminal 101 and / or the CG resources unavailable to the terminal 101. For example, the terminal 101 determines that the configured grant is a shared configured grant, the configured grant is associated with one or more CG resources, the configured grant is shared among one or more terminals, the terminal 101 belongs to the one or more terminals, and after the terminal 101 determines the CG resources not used and / or the CG resources used from the one or more CG resources, the terminal 101 can indicate the CG resources used and / or the CG resources not used to the network device 102 through the first information. The network device 102 can indicate the CG resources available to the terminal from the one or more terminals through the first information. For example, the network device 102 can receive the first information sent by one or more terminals, each terminal sends the first information indicating the CG resources not used and / or the CG resources used by the corresponding terminal, and when two or more terminals indicate the same CG resource is used, the network device 102 can be responsible for solving the conflict, for example, indicating which terminal uses the CG resource. Alternatively, when the network device 102 receives the first information sent by one or more terminals, each terminal sends the first information indicating the CG resources not used and / or the CG resources used by the corresponding terminal, and when two or more terminals indicate the same CG resource is used, and the terminal 101 belongs to the two or more terminals, the network device 102 can send the first information to the two or more terminals, the first information sent by the network device 102 to the two or more terminals is not the same information, and the different first information indicates the CG resources available to the corresponding terminal and / or the CG resources unavailable to the corresponding terminal. For example, the first information can be any one of the following: PDCCH scrambled by a second RNTI; MAC (Media Access Control) CE (Control Element); and RRC signaling. For example, the second RNTI can be a newly defined RNTI, and the second RNTI is a UE-based RNTI, for example, UE-Specific RNTI, that is, the second RNTI can be a scrambling code that can be scrambled by UE-Specific. For example, the network device 102 can send one or more first information to one or more terminals sharing the configured grant, for example, one first information corresponds to one terminal, and for each terminal receiving the first information, the first information indicates the CG resources available to the terminal and / or the CG resources unavailable to the terminal.

[0130] In step S2102, the terminal 101 determines the priority associated with the first CG resource.

[0131] In some embodiments, the first CG resource can be a CG resource of one or more CG resources indicated by the first configured grant, the first configured grant being a shared configured grant, the first configured grant being shared among a plurality of terminals, the terminal 101 being a terminal of the plurality of terminals. In case that the first CG resource can be a CG resource of one or more CG resources indicated by the shared first configured grant, if the terminal 101 wants to use the first CG resource, the terminal 101 can determine whether the first CG resource is available, i.e., whether the first CG resource can be used by the terminal 101, by the priority associated with the first CG resource. Or, in case that the first CG resource can be a CG resource of one or more CG resources indicated by the shared first configured grant and the first CG resource is a CG resource indicated by the network device 102 as available, if the terminal 101 wants to use the first CG resource, the terminal 101 can determine whether the first CG resource is available. Or, in case that the first CG resource is a CG resource of one or more CG resources indicated by the shared first configured grant, if the first CG resource is a CG resource to be used by the terminal 101, e.g., the terminal 101 reports to the network device 102 the CG resource to be used by the terminal 101 through the second information, the terminal 101 can determine whether the first CG resource is available by the priority associated with the first CG resource. Or, in case that the first CG resource can be a CG resource of one or more CG resources indicated by the shared first configured grant, if the first CG resource is a CG resource reported by the terminal 101 through the second information as the CG resource to be used by the terminal 101 but the terminal 101 does not receive the first information from the network device 102 for indicating whether the first CG resource is available to the terminal 101 and the transmission time of the first CG resource is going to or has arrived, the terminal 101 can determine whether the first CG resource is available by the priority associated with the first CG resource. Or, in case that the first CG resource can be a CG resource of one or more CG resources indicated by the shared first configured grant, if the first CG resource is a CG resource through which the terminal 101 transmits the second information, the terminal 101 can determine whether the first CG resource is available by the priority associated with the first CG resource.

[0132] For example, the priority can be a priority of a MAC (Media Access Control) PDU (Protocol Data Unit) associated with the first CG resource. In some embodiments, the terminal 101 determines the MAC PDU associated with the first CG resource, determines the priority of the MAC PDU associated with the first CG resource as the priority associated with the first CG resource. For example, the terminal 101 can determine one or more LCHs (Logical Channels) associated with the MAC PDU, and determine the highest logical channel priority among the one or more LCHs as the priority of the MAC PDU associated with the first CG resource.

[0133] For example, the terminal 101 predicts that the first CG resource is associated with a first MAC PDU, the first MAC PDU is associated with LCHs LCH1, LCH2 and LCH3, where the logical channel priority of LCH1 is 1, the logical channel priority of LCH2 is 3, and the logical channel priority of LCH3 is 2, the terminal 101 determines that the priority of the first MAC PDU is 1, and determines that the priority associated with the first CG resource is 1.

[0134] In some embodiments, the first CG resource is a shared configured grant, step S2102 is performed.

[0135] In step S2103, the terminal 101 determines whether the first CG resource can be used by the terminal 101 according to the priority associated with the first CG resource.

[0136] For example, after determining the priority associated with the first CG resource, the terminal 101 can compare the priority associated with the first CG resource with a predetermined threshold, and determine whether the first CG resource can be used by the terminal 101 according to the comparison result.

[0137] In some embodiments, the priority associated with the first CG resource is less than the predetermined threshold, and the terminal 101 determines that the first CG resource can be used by the terminal 101. That is, when the terminal 101 determines that the priority associated with the first CG resource is less than the predetermined threshold (or the value of the priority associated with the first CG resource is less than the predetermined threshold, or the priority associated with the first CG resource is higher than the predetermined threshold), the terminal 101 can determine that the first CG resource can be used by the terminal 101.

[0138] In some embodiments, the terminal 101 determines that the first CG resource is not available to the terminal 101 if the priority associated with the first CG resource is greater than a predetermined threshold. That is, if the terminal 101 determines that the priority associated with the first CG resource is greater than the predetermined threshold (or, the priority associated with the first CG resource has a value greater than the predetermined threshold, or the priority associated with the first CG resource is lower than the predetermined threshold), the terminal 101 can determine that the first CG resource is not available to the terminal 101.

[0139] In some embodiments, the terminal 101 determines that the first CG resource is available to the terminal 101 if the priority associated with the first CG resource is equal to a predetermined threshold. That is, if the terminal 101 determines that the priority associated with the first CG resource is equal to the predetermined threshold (or, the priority associated with the first CG resource has a value equal to the predetermined threshold), the terminal 101 can determine that the first CG resource is available to the terminal 101.

[0140] In some embodiments, the terminal 101 determines that the first CG resource is not available to the terminal 101 if the priority associated with the first CG resource is equal to a predetermined threshold. That is, if the terminal 101 determines that the priority associated with the first CG resource is equal to the predetermined threshold (or, the priority associated with the first CG resource has a value equal to the predetermined threshold), the terminal 101 can determine that the first CG resource is not available to the terminal 101.

[0141] In some embodiments, the predetermined threshold can be agreed by a protocol. In some embodiments, the predetermined threshold can be configured by the network device. For example, the network device 102 sends second configuration information to the terminal 101, and the terminal 101 receives the second configuration information sent by the network device 102, where the second configuration information includes the predetermined threshold, and the predetermined threshold is used to determine whether the first CG resource is available. For example, the predetermined threshold can be configured according to a configured grant granularity. For example, the second configuration information can be a high-layer parameter (such as ConfiguredGrantConfig), and the predetermined threshold is defined in the ConfiguredGrantConfig. For example, the predetermined threshold can be a specific value, for example, the predetermined threshold can be a value in 1-16. For example, the predetermined threshold can be a value range.

[0142] In some embodiments, the first configuration information and the second configuration information are the same information or different information. For example, the second configuration information and the first configuration information can be the same RRC (Radio Resource Control) signaling or different RRC signaling. For example, the first configuration information and the second configuration information are the same information, i.e., the one or more CG resources and the predetermined threshold associated with the first configured grant are configured to the terminal 101 by the same configuration information (e.g., ConfiguredGrantConfig).

[0143] Optionally, in some embodiments, as shown in FIG. 2A, the method can further include step S2104. In step S2104, the first CG resource can be used by the terminal 101, and the terminal 101 transmits the MAC PDU associated with the first CG resource on the first CG resource. That is, when the terminal 101 determines that the first CG resource can be used by the terminal 101, the terminal 101 can transmit the MAC PDU associated with the first CG resource on the first CG resource.

[0144] Optionally, in some embodiments, as shown in FIG. 2A, the method can further include step S2105. In step S2105, the first CG resource cannot be used by the terminal 101, and the terminal 101 determines the CG resource that can be used by the terminal 101 according to the first backoff value. That is, when the terminal 101 determines that the first CG resource cannot be used by the terminal 101, the terminal 101 can determine the CG resource that can be used by the terminal 101 according to the first backoff value. For example, the terminal can determine the CG resource that can be used by the terminal from the other CG resources associated with the first configured grant according to the first backoff value. For example, the first backoff value can be expressed in absolute time, such as Slot, Symbol, s (second), ms (millisecond), us (microsecond), min (minute), h (hour), etc. For example, the first backoff value indicates the number of backoff CG resources, or the first backoff value indicates the number of backoff configured grants.

[0145] In some embodiments, a possible implementation of determining the CG resource that can be used by the terminal 101 according to the first backoff value includes: starting a first timer, the duration of the first timer being the first backoff value; determining the second CG resource as the CG resource that can be used by the terminal 101, the second CG resource being the Xth CG resource after the first timer expires, X being a positive integer, the second CG resource being a CG resource in the one or more CG resources indicated by the first configured grant, wherein the first configured grant is a shared configured grant. Or in the case that the first configured grant is a shared configured grant, the second CG resource can be a CG resource in the one or more CG resources indicated by the shared first configured grant. The second CG resource is different from the first CG resource. For example, the first backoff value is expressed in absolute time, the terminal 101 determines that the first CG resource cannot be used by the terminal 101, and the terminal 101 starts the first timer at the end of the first CG resource, the duration of the first timer being the first backoff value. The terminal 101 can determine the Xth CG resource after the first timer expires as the CG resource that can be used by the terminal 101, for example, the terminal 101 can determine the first CG resource after the first timer expires as the CG resource that can be used by the terminal 101. In some embodiments, the first backoff value and / or X can be agreed upon by the protocol; or the first backoff value and / or X can also be configured by the network device. For example, the network device 102 sends the third configuration information to the terminal 101, and the terminal 101 receives the third configuration information sent by the network device 102, the third configuration information including the first backoff value and / or X, which can be used by the terminal 101 to determine the CG resource that can be used by the terminal 101. For example, the first backoff value and / or X can be configured according to the granularity of the configured grant, for example, the third configuration information can be a high layer parameter (such as ConfiguredGrantConfig), for example, the first backoff value and / or X are defined in ConfiguredGrantConfig.

[0146] In some embodiments, the first configuration information and the third configuration information are the same information or are different information; or the first configuration information, the second configuration information and the third configuration information can be the same information or can be different information. For example, the third configuration information and the first configuration information can be the same RRC signaling or can be different RRC signaling. For example, the first configuration information, the second configuration information and the third configuration information can be the same RRC signaling or can be different RRC signaling. For example, the first configuration information and the third configuration information are the same information, that is, the one or more CG resources associated with the first configured grant, the first backoff value and / or X are configured to the terminal 101 by the same configuration information (such as ConfiguredGrantConfig). For example, the first configuration information, the second configuration information and the third configuration information can be the same information, that is, the one or more CG resources associated with the first configured grant, the first backoff value and / or X, the predetermined threshold are configured to the terminal 101 by the same configuration information (such as ConfiguredGrantConfig).

[0147] Optionally, in some embodiments, the terminal 101 determines that the first information sent by the network device 102 is not received before the end of the first backoff value, and the terminal 101 sends the MAC PDU associated with the first CG resource on the second CG resource; wherein the first information is used to indicate the CG resource available to the terminal 101 and / or the CG resource unavailable to the terminal 101. For example, the first backoff value is expressed by an absolute time, the terminal 101 determines that the first CG resource is unavailable to the terminal 101, the terminal 101 starts the first timer at the end of the first CG resource, the duration of the first timer is the first backoff value, if the terminal 101 does not receive the first information sent by the network device 102 before the end of the first backoff value (or the terminal 101 does not receive the first information sent by the network device 102 during the running of the first timer, or the first timer expires and the terminal 101 does not receive the first information sent by the network device 102, or the terminal 101 does not receive the first information sent by the network device 102 during the backoff), the terminal 101 determines the second CG resource (i.e. the Xth CG resource after the expiration of the first timer) as the CG resource available to the terminal 101. For example, the terminal 101 can send the MAC PDU associated with the first CG resource on the second CG resource. For example, the second CG resource can be a CG resource in the one or more CG resources indicated by the first configuration grant, wherein the first configuration grant is a shared configuration grant. Or in the case that the first configuration grant is a shared configuration grant, the second CG resource can be a CG resource in the one or more CG resources indicated by the shared first configuration grant. The second CG resource is different from the first CG resource.

[0148] Optionally, in some embodiments, a possible implementation of the terminal 101 determining the CG resource available to the terminal 101 according to the first backoff value includes: starting a first timer, the duration of the first timer being the first backoff value; determining that the first information (the first information being used to indicate the CG resource available to the terminal 101 and / or the CG resource unavailable to the terminal 101) sent by the network device 102 is received before the end of the first backoff value; determining the fourth CG resource (the fourth CG resource being the CG resource available to the terminal 101 closest to the end of the first information, for example, the fourth CG resource being the CG resource available to the terminal 101 closest to the end of the slot of the first information) according to the first information; and determining the fourth CG resource as the CG resource available to the terminal 101. For example, the first backoff value is expressed by an absolute time, the terminal 101 determines that the first CG resource is unavailable to the terminal 101, and the terminal 101 starts the first timer at the end of the first CG resource, the duration of the first timer being the first backoff value. If the terminal 101 receives the first information sent by the network device 102 before the end of the first backoff value (or, the terminal 101 receives the first information sent by the network device 102 during the running of the first timer, or, the terminal 101 receives the first information sent by the network device 102 during the backoff), the terminal 101 determines the fourth CG resource (the fourth CG resource being the CG resource available to the terminal 101 closest to the end of the first information, for example, the fourth CG resource being the CG resource available to the terminal 101 closest to the end of the slot of the first information) according to the first information, and the terminal 101 can determine the fourth CG resource as the CG resource available to the terminal 101.

[0149] Optionally, in some embodiments, the terminal 101 stops the first timer when it is determined that the start time of the fourth CG resource is before the end of the first backoff value. For example, the terminal 101 stops the first timer when it is determined that the transmission time of the fourth CG resource is before the end of the first backoff value. Optionally, in some embodiments, the terminal 101 transmits the MAC PDU associated with the first CG resource on the fourth CG resource. For example, the terminal 101 determines the fourth CG resource as the CG resource available to the terminal 101, and can transmit the MAC PDU associated with the first CG resource on the fourth CG resource. In some embodiments, the terms such as “start time” and “transmission time” in this article can be replaced with each other.

[0150] It should be noted that the fourth CG resource in this article can be a CG resource in one or more CG resources indicated by the first configured grant, and the first configured grant is a shared configured grant. Alternatively, in the case where the first configured grant is a shared configured grant, the fourth CG resource can be a CG resource in one or more CG resources indicated by the shared first configured grant. The fourth CG resource is different from the first CG resource.

[0151] It should be noted that the terminal 101 can not maintain the first timer, and the maintenance can be understood as the operation related to the first timer such as starting, restarting, resetting, etc., which can also be called maintaining the first timer. Alternatively, in some embodiments, a possible implementation manner of determining the CG resource that can be used by the terminal 101 according to the first backoff value includes: based on the end of determining the first backoff value, the Xth CG resource after the end of the first backoff value (X is a positive integer) is determined as the CG resource that can be used by the terminal 101. If the terminal 101 does not receive the first information sent by the network device 102 before the end of the first backoff value, the terminal 101 can send the MAC PDU associated with the first CG resource on the Xth CG resource after the end of the first backoff value. For example, if the terminal 101 receives the first information sent by the network device 102 before the end of the first backoff value, the terminal 101 can determine the fourth CG resource closest to the end of the first information (such as the end of the time slot of the first information) as the available CG resource indicated by the first information, and the terminal 101 determines the fourth CG resource as the CG resource that can be used by the terminal 101. For example, the terminal 101 can send the MAC PDU associated with the first CG resource on the fourth CG resource. In some embodiments, the above-mentioned first backoff value and / or X can be agreed by the protocol; or the above-mentioned first backoff value and / or X can also be configured by the network device.

[0152] Optionally, in some embodiments, a possible implementation of determining the CG resource that can be used by the terminal 101 according to the first backoff value includes: determining a second backoff value according to the first backoff value; starting a second timer, the duration of the second timer being the second backoff value; determining a third CG resource as the CG resource that can be used by the terminal 101, the third CG resource being the Yth CG resource after the second timer expires, Y being a positive integer. For example, when the first backoff value is expressed in absolute time, the terminal 101 can randomly select a value between 0 and the first backoff value as the second backoff value, the terminal 101 determines that the first CG resource cannot be used by the terminal 101, and the terminal 101 starts the second timer at the end of the first CG resource, the duration of the second timer being the second backoff value. The terminal 101 can determine the Yth CG resource after the second timer expires as the CG resource that can be used by the terminal 101, for example, the terminal 101 can determine the first CG resource after the second timer expires as the CG resource that can be used by the terminal 101. In some embodiments, the first backoff value and / or Y can be agreed upon by the protocol; or the first backoff value and / or Y can also be configured by the network device. For example, the network device 102 sends fourth configuration information to the terminal 101, and the terminal 101 receives the fourth configuration information sent by the network device 102, the fourth configuration information including the first backoff value and / or Y, which can be used by the terminal 101 to determine the CG resource that can be used by the terminal 101. For example, the first backoff value and / or Y can be configured according to the configured grant granularity, for example, the fourth configuration information can be a high-layer parameter (such as ConfiguredGrantConfig), for example, the first backoff value and / or Y are defined in ConfiguredGrantConfig.

[0153] It should be noted that the third CG resource in this paper can be a CG resource in one or more CG resources indicated by a first configured grant, wherein the first configured grant is a shared configured grant. Or in the case of a shared first configured grant, the third CG resource can be a CG resource in one or more CG resources indicated by the shared first configured grant. The third CG resource is different from the first CG resource.

[0154] In some embodiments, the first configuration information and the fourth configuration information are the same information or are different information. Alternatively, the first configuration information, the second configuration information and the fourth configuration information can be the same information or can be different information. For example, the fourth configuration information and the first configuration information can be the same RRC signaling or can be different RRC signaling. Alternatively, the first configuration information, the second configuration information and the fourth configuration information can be the same RRC signaling or can be different RRC signaling. Alternatively, the first configuration information and the fourth configuration information are the same information, i.e., the one or more CG resources associated with the first configured grant, the first backoff value and / or Y are configured to the terminal 101 by the same configuration information (e.g., ConfiguredGrantConfig). Alternatively, the first configuration information, the second configuration information and the fourth configuration information can be the same information, i.e., the one or more CG resources associated with the first configured grant, the first backoff value and / or Y, and the predetermined threshold are configured to the terminal 101 by the same configuration information (e.g., ConfiguredGrantConfig).

[0155] Optionally, in some embodiments, the terminal 101 determines that the first information sent by the network device 102 is not received before the end of the second backoff value, and the terminal 101 sends the MAC PDU associated with the first CG resource on the third CG resource. The first information is used to indicate the available CG resource and / or the unavailable CG resource of the terminal 101. For example, when the first backoff value is represented by an absolute time, the terminal 101 can randomly select a value between 0 and the first backoff value as the second backoff value. The terminal 101 determines that the first CG resource is unavailable to the terminal 101. The terminal 101 starts a second timer at the end of the first CG resource, and the duration of the second timer is the second backoff value. If the terminal 101 does not receive the first information sent by the network device 102 before the end of the second backoff value (or the terminal 101 does not receive the first information sent by the network device 102 during the running of the second timer, or the second timer expires and the terminal 101 does not receive the first information sent by the network device 102, or the terminal 101 does not receive the first information sent by the network device 102 during the backoff period), the terminal 101 determines that the third CG resource (i.e., the Yth CG resource after the expiration of the second timer) is available to the terminal 101. For example, the terminal 101 can send the MAC PDU associated with the first CG resource on the third CG resource.

[0156] Optionally, in some embodiments, a possible implementation of determining the CG resource available to the terminal 101 according to the first backoff value includes: determining a second backoff value according to the first backoff value; starting a second timer (the duration of the second timer is the second backoff value); determining that the first information (the first information is used to indicate the CG resource available to the terminal 101 and / or the CG resource unavailable to the terminal 101) sent by the network device 102 is received before the end of the second backoff value; determining a fourth CG resource (the fourth CG resource is the available CG resource closest to the end of the first information indicated by the first information, for example, the fourth CG resource is the available CG resource closest to the slot end of the first information indicated by the first information) according to the first information; determining the fourth CG resource as the CG resource available to the terminal 101. For example, taking the first backoff value expressed in absolute time as an example, the terminal 101 can randomly select a value between 0 and the first backoff value as the second backoff value, the terminal 101 determines that the first CG resource is unavailable to the terminal 101, and the terminal 101 starts the second timer at the end of the first CG resource. The duration of the second timer is the second backoff value. If the terminal 101 receives the first information sent by the network device 102 before the end of the second backoff value (or, the terminal 101 receives the first information sent by the network device 102 during the running of the second timer, or, the terminal 101 receives the first information sent by the network device 102 during the backoff period), the terminal 101 determines the available CG resource closest to the end of the first information (such as the slot end of the first information) indicated by the first information as the fourth CG resource, and the terminal 101 can determine the fourth CG resource as the CG resource available to the terminal 101.

[0157] Optionally, in some embodiments, the terminal 101 stops the second timer when it is determined that the start time of the fourth CG resource is before the end of the second backoff value. For example, the terminal 101 stops the second timer when it is determined that the transmission time of the fourth CG resource is before the end of the second backoff value. Optionally, in some embodiments, the terminal 101 transmits the MAC PDU associated with the first CG resource on the fourth CG resource. For example, after the terminal 101 determines the fourth CG resource as the CG resource available to the terminal 101, the terminal 101 can transmit the MAC PDU associated with the first CG resource on the fourth CG resource.

[0158] It should be noted that the terminal 101 can not maintain the second timer, and the maintenance of the second timer can be understood as starting, restarting, resetting, and the like, which are related to the second timer, and the like, and can be referred to as maintaining the second timer. Alternatively, in some embodiments, a possible implementation manner in which the terminal 101 determines the CG resource that can be used by the terminal 101 according to the first backoff value includes: determining the second backoff value according to the first backoff value; determining the Yth CG resource after the end of the second backoff value (Y is a positive integer) as the CG resource that can be used by the terminal 101 based on the end of the implementation of determining the second backoff value. If the terminal 101 does not receive the first information sent by the network device 102 before the end of the second backoff value, the terminal 101 can send the MAC PDU associated with the first CG resource on the Yth CG resource after the end of the second backoff value. For example, if the terminal 101 receives the first information sent by the network device 102 before the end of the second backoff value, the terminal 101 can determine the fourth CG resource closest to the end of the first information (such as the end of the time slot of the first information) as the available CG resource, and the terminal 101 determines the fourth CG resource as the CG resource that can be used by the terminal 101. For example, the terminal 101 can send the MAC PDU associated with the first CG resource on the fourth CG resource. In some embodiments, the first backoff value and / or Y described above can be agreed by a protocol; alternatively, the first backoff value and / or Y described above can also be configured by the network device.

[0175] Figure 2B is an interaction diagram of a communication method according to an embodiment of the present disclosure. As shown in Figure 2B, the embodiments of the present disclosure relate to a communication method applicable to the communication system 100, and the above method includes but is not limited to the following steps.

[0176] Step S2201: The network device 102 sends first configuration information of a first configured grant to the terminal 101.

[0177] In some embodiments, the first configured grant is a shared configured grant. In some embodiments, the first configured grant is associated with one or more CG resources. In some embodiments, the first configuration information is used by the terminal 101 to determine whether a first CG resource, which belongs to the one or more CG resources, can be used by the terminal 101.

[0178] Optional implementations of step S2201 can be found in the optional implementations of step S2101 of Figure 2A and other associated parts in the embodiments related to Figure 2A, which will not be described here.

[0179] Step S2202: The first CG resource is a CG resource that is not indicated to be used, and the terminal 101 determines that the first CG resource can be used by the terminal 101.

[0180] In some embodiments, the first CG resource is a CG resource that is not indicated as available, including at least one of the following: the first CG resource is a CG resource that is not indicated as available by the network device; the first CG resource is a CG resource that the terminal 101 reports to the network device 102 through the second information, but the terminal 101 does not receive the first information from the network device 102 indicating whether the first CG resource is available to the terminal 101, and a transmission time of the first CG resource is about to arrive or has arrived; and the first CG resource is a CG resource through which the terminal 101 transmits the second information. For example, the first CG resource can be a CG resource that is not indicated as available by the network device 102. For example, the first CG resource can be a CG resource that the terminal 101 is about to use, e.g., the terminal 101 reports to the network device 102 through the second information that the terminal 101 is about to use the CG resource. For example, the first CG resource is a CG resource that the terminal 101 reports to the network device 102 through the second information, but the terminal 101 does not receive the first information from the network device 102 indicating whether the first CG resource is available to the terminal 101, and a transmission time of the first CG resource is about to arrive or has arrived. For example, the first CG resource can be a CG resource through which the terminal 101 transmits the second information.

[0181] For example, when the first CG resource is a CG resource that is not indicated as available by the network device, the terminal 101 determines that the first CG resource is available to the terminal 101.

[0182] For example, when the first CG resource is a CG resource that the terminal 101 is about to use, e.g., the terminal 101 reports to the network device 102 through the second information that the terminal 101 is about to use the CG resource, the terminal 101 can determine that the first CG resource is available to the terminal 101.

[0183] For example, when the terminal 101 reports to the network device 102 through the second information that the terminal 101 is about to use the CG resource, the first CG resource is a CG resource that the terminal 101 reports to the network device 102 through the second information, but the terminal 101 does not receive the first information from the network device 102 indicating whether the first CG resource is available to the terminal 101, and a transmission time of the first CG resource is about to arrive or has arrived, the terminal 101 can determine that the first CG resource is available to the terminal 101. The above description of the first information and the second information can refer to the description of the first information and the second information in step S2101 of FIG. 2A, and will not be repeated here.

[0184] For example, when the first CG resource is a CG resource through which the terminal 101 transmits the second information, the terminal 101 can determine that the first CG resource is available to the terminal 101.

[0185] In step S2203, the first CG resource is a CG resource not indicated as available, and the terminal 101 determines that the first CG resource is not available for use by the terminal.

[0186] In some embodiments, the first CG resource is a CG resource not indicated as available, including at least one of the following: the first CG resource is a CG resource not indicated as available by the network device; the first CG resource is a CG resource to be used by the terminal 101 reported by the terminal 101 through the second information, but the terminal 101 has not received the first information from the network device 102 for indicating whether the first CG resource is available for use by the terminal 101, and a transmission time of the first CG resource will arrive or has arrived; and the first CG resource is a CG resource for transmitting the second information by the terminal 101. For example, the first CG resource can be a CG resource not indicated as available by the network device 102. For example, the first CG resource can be a CG resource to be used by the terminal 101, for example, the terminal 101 reports the CG resource to be used by the terminal 101 to the network device 102 through the second information. For example, the first CG resource is a CG resource to be used by the terminal 101 reported by the terminal 101 through the second information, but the terminal 101 has not received the first information from the network device 102 for indicating whether the first CG resource is available for use by the terminal 101, and a transmission time of the first CG resource will arrive or has arrived. For example, the first CG resource can be a CG resource for transmitting the second information by the terminal 101.

[0187] For example, when the first CG resource is a CG resource not indicated as available by the network device, the terminal 101 determines that the first CG resource is not available for use by the terminal 101.

[0188] For example, when the first CG resource is a CG resource to be used by the terminal 101, for example, the terminal 101 reports the CG resource to be used by the terminal 101 to the network device 102 through the second information, the terminal 101 can determine that the first CG resource is not available for use by the terminal 101.

[0189] For example, when the terminal 101 reports the CG resource to be used by the terminal 101 to the network device 102 through the second information, the first CG resource is a CG resource to be used by the terminal 101 reported by the terminal 101 through the second information, but the terminal 101 has not received the first information from the network device 102 for indicating whether the first CG resource is available for use by the terminal 101, and a transmission time of the first CG resource will arrive or has arrived, the terminal 101 can determine that the first CG resource is not available for use by the terminal 101.

[0190] For example, when the first CG resource is a CG resource for transmitting the second information by the terminal 101, the terminal 101 can determine that the first CG resource is not available for use by the terminal 101.

[0191] Optionally, in some embodiments, the first CG resource can be used by the terminal 101, and the terminal 101 transmits the MAC PDU associated with the first CG resource on the first CG resource. The optional implementation can refer to the optional implementation of step S2104 in FIG. 2A and other associated parts in the embodiments involved in FIG. 2A, which will not be repeated here.

[0192] Optionally, in some embodiments, the first CG resource cannot be used by the terminal 101, and the terminal 101 determines the CG resource that can be used by the terminal 101 according to the first backoff value. The optional implementation can refer to the optional implementation of step S2105 in FIG. 2A and other associated parts in the embodiments involved in FIG. 2A, which will not be repeated here.

As shown in FIG. 5, the method according to the embodiments of the present disclosure can be applied to the communication system 100, and the method comprises but is not limited to the following steps.

[0267] In step S5101, the network device 102 sends first configuration information of a first configuration grant to the terminal 101; the first configuration grant is a shared configuration grant, and the first configuration grant is associated with one or more configuration grant CG resources, the one or more configuration grant CG resources comprising the first CG resource, or the first CG resource being a CG resource in the one or more CG resources associated with the first configuration grant.

[0268] In some embodiments, the first configuration information is used by the terminal 101 to determine whether the first CG resource can be used by the terminal 101.

[0269] The optional implementation of step S5101 can be referred to the optional implementation of step S2101 in FIG. 2A and other associated parts in the embodiments involved in FIG. 2A, which will not be repeated here.

[0270] Step S5102. The terminal 101 determines whether the first CG resource can be used by the terminal 101.

[0271] The optional implementation of step S5101 can refer to step S2103 in FIG. 2A, step S2202 in FIG. 2B, the optional implementation of step S2203 in FIG. 2B, and other associated parts in the embodiments related to FIG. 2A and FIG. 2B, which are not described herein again.

[0272] In some embodiments, the above method can include the method described in the above terminal-side, network device-side, and the like embodiments, which are not described herein again.

[0273] It is worth noting that the embodiments of the present disclosure provide a transmission method of configured grant, which solves the problem of how the terminal device determines whether the configured grant is available in the case that the terminal device does not receive the indication information of whether the configured grant is available in the scenario of sharing the configured grant. The embodiments will be described in detail below.

[0274] In some embodiments, a predetermined threshold is defined, and the terminal determines whether the configured grant is available according to the predetermined threshold. For example, the predetermined threshold is configured according to the configured grant configuration granularity. For example, the predetermined threshold is defined in ConfiguredGrantConfig. For example, the predetermined threshold is a specific value, for example, a value in 1-16. For example, the predetermined threshold is a value range.

[0275] In some embodiments, the terminal determines that the priority associated with the first configured grant is less than the predetermined threshold, and the terminal determines that the first configured grant can be used.

[0276] For example, the first configured grant is a configured grant that is not indicated by the network device to be available. For example, the first configured grant is a configured grant to be used by the terminal, for example, the configured grant to be used by the terminal is reported to the network device through the indication information. For example, the terminal sends an indication message to indicate the configured grant to be used and / or the configured grant not to be used. The indication information indicates that the first configured grant is to be used. The terminal does not receive the indication information from the network device indicating whether the first configured grant is available, and the sending time of the first configured grant has arrived. For example, the first configured grant is the configured grant for which the terminal sends the indication message.

[0277] The terminal determines a priority of the first configured grant association. The priority is, for example, a priority of a MAC PDU associated with the first configured grant association. The priority is, for example, a highest logical channel priority of one or more LCHs associated with the MAC PDU associated with the first configured grant association. For example, the UE predicts a MAC PDU associated with the first configured grant, and the MAC PDU is associated with LCH1, LCH2, and LCH3, where the logical channel priority of LCH1 is 1, the logical channel priority of LCH2 is 3, and the logical channel priority of LCH3 is 2. The priority of the first MAC PDU is 1, and the priority of the first configured grant association is further 1.

[0278] The terminal determines that the first configured grant can be used when the priority of the first configured grant association is less than a predetermined threshold (the priority is less than the predetermined threshold or the priority is higher than the predetermined threshold). The terminal determines that the first configured grant cannot be used when the priority of the first configured grant association is greater than the predetermined threshold. The terminal determines that the first configured grant can be used when the priority of the first configured grant association is equal to the predetermined threshold. The terminal determines that the first configured grant cannot be used when the priority of the first configured grant association is equal to the predetermined threshold.

[0279] In some embodiments, a first backoff value is defined, and the terminal determines the available configured grant according to the first backoff value.

[0280] The first backoff value is, for example, configured in a granularity of a configured grant configuration, and the first backoff value is, for example, defined in ConfiguredGrantConfig. The first backoff value is, for example, expressed in an absolute time, such as a slot, a symbol, and the like. The first backoff value is, for example, indicative of a number of backoff configured grants.

[0281] The terminal determines that the first configured grant cannot be used, and starts a first timer, where a duration of the first timer is set as the first backoff value. The first configured grant after the first timer expires is the second configured grant. The terminal can not maintain the first timer, and the end of the first backoff value is determined.

[0282] The terminal randomly selects a value between 0 and the first backoff value as a second backoff value. The terminal determines that the first configured grant cannot be used, and starts a second timer, where a duration of the second timer is set as the second backoff value. The first configured grant after the second timer expires is the third configured grant. The terminal can not maintain the second timer, and the end of the second backoff value is determined.

[0283] For example, the terminal determines that the first information (before the end of the first backoff value / second backoff value) sent by the network device is received during the backoff period, and the first information is used to indicate the available configuration grant and / or unavailable configuration grant of the terminal. The terminal determines the latest available configuration grant indicated by the first information (for example, the fourth configuration grant closest to the first message), and the terminal sends the data associated with the first configuration grant using the fourth configuration grant.

[0284] For example, the terminal determines that the first information (before the end of the first backoff value / second backoff value) sent by the network device is not received during the backoff period, and the first information is used to indicate the available configuration grant and / or unavailable configuration grant of the terminal. The terminal sends the data associated with the first configuration grant using the second configuration grant / third configuration grant.

[0285] In some embodiments, the terminal determines that the configuration grant that is not indicated to be available can be used or the terminal determines that the configuration grant that is not indicated to be available cannot be used. For example, the configuration grant is a configuration grant that is not indicated to be available by the network device. For example, the configuration grant is a configuration grant to be used by the terminal, for example, the terminal reports the configuration grant to be used to the network device through the indication information. For example, the terminal sends the indication information indicating the configuration grant to be used and / or the configuration grant not to be used, the indication information indicates that the configuration grant is to be used, the terminal does not receive the indication information from the network device indicating whether the configuration grant is available, and the sending time of the configuration grant has arrived. For example, the configuration grant is the configuration grant through which the terminal sends the indication information.

[0286] The embodiments of the present disclosure also provide a device for implementing any of the above methods. For example, a device is provided, which includes units or modules for implementing the steps performed by the terminal in any of the above methods.
