[0118] As shown in Figure 1, the communication system 100 includes a terminal 101 and a network device 102.

In this case, the interfaces between or within access network devices involved in the embodiments of this disclosure can be transformed into internal interfaces of Open RAN. The processes and information interactions between these internal interfaces can be implemented by software or programs.
[0123] In some embodiments, the access network device may be composed of a central unit (CU) and a distributed unit (DU). The CU may also be called a control unit. The CU-DU structure can separate the protocol layer of the access network device. Some of the protocol layer functions are centrally controlled by the CU, while the remaining part or all of the protocol layer functions are distributed in the DU and centrally controlled by the CU. However, this is not the only possibility.
[0124] In some embodiments, a core network device may be a single device comprising one or more network elements, or it may be multiple devices or a group of devices, each comprising all or part of the aforementioned one or more network elements. Network elements may be virtual or physical. The core network may include, for example, at least one of an Evolved Protocol Core (EPC), a 5G Core Network (5GCN), or a Next Generation Core (NGC).
[0125] It is understood that the communication system described in this disclosure is for the purpose of more clearly illustrating the technical solutions of this disclosure, and does not constitute a limitation on the technical solutions proposed in this disclosure.

[0128] To support faster data management, the relevant protocols provide semi-persistent resource configuration methods for both uplink and downlink data. These include: Configured Grant (CG) for uplink data transmission and Semi-Persistent Scheduling (SPS) for downlink data transmission.
[0129] Optionally, CG includes CG Type-1 and CG Type-2. CG Type-1 refers to uplink resource configuration that provides the uplink resource period and specific allocation of uplink time-frequency resources via Radio Resource Control (RRC) messages. Upon receiving this configuration, the UE directly uses the configured uplink resources to transmit uplink data (i.e., uplink resources are activated immediately after RRC configuration). CG Type-2 refers to uplink resource configuration that occurs during the RRC message's configuration period, with Physical Downlink Control Channel (PDCCH) control signaling activating and indicating the specific allocation of uplink time-frequency resources. The UE can only use the configured uplink resources to transmit uplink data after the PDCCH control signaling activates the uplink resource configuration.
[0130] Optionally, SPS scheduling refers to the period for configuring downlink resources in the RRC message, and the PDCCH control signaling activation indicating the specific allocation of downlink time-frequency resources. The UE can only receive downlink data using the configured downlink resources after the PDCCH control signaling activates the downlink resource configuration.
[0131] In addition, Small Data Transmission (SDT) was introduced, which allows UEs in inactive states to send small data packets using CG-SDT resources.
[0132] In related technologies, CG resources are dedicated resources for use by a single UE. These CG resources are more suitable for periodic services. However, for non-periodic services, such as burst services, dedicated CG resources are not ideal.
[0133] Optionally, if the burst service has high latency requirements, such as 0.1 milliseconds (ms), then by using shared CG resources, not only can latency be reduced, but resource utilization efficiency can also be improved, because if one UE does not send data, other UEs can still send data through the same resource.
[0134] One problem that needs to be solved when using shared CG resources for uplink data transmission is the identification problem, such as UE identification.
[0135] Typically, existing CG activation downlink control information (DCI) uses a UE-specific Radio Network Temporary Identity (RNTI), such as a Configured Scheduling (CS) RNTI, to address the UE. The UE listens on a specific PDCCH for the DCI addressed by that CS-RNTI to receive the activation indication. However, when multiple UEs share the same CG resource, this UE-specific CS-RNTI cannot be used; instead, a group RNTI must be used to address a group of UEs. Furthermore, the DCI cannot be sent on a UE-specific PDCCH but must be sent on a group-common PDCCH. Additionally, messages sent using shared CG resources need to carry the UE ID so that the network device knows which UE sent the message. The network device then needs to perform contention resolution to inform the UE whether the contention was successful.
[0136] This disclosure proposes a method for determining the identifier when using shared resources. By configuring the identifier associated with the shared resources for the terminal, it ensures that the terminal can use the shared resources to process services, minimizes the latency of sudden service interruptions, improves the reliability of sudden service interruptions, and improves the utilization rate of shared resources.

[0141] In some embodiments, the shared CG resources described above can be CG Type 1 resources or CG Type 2 resources. A network device can configure multiple shared CG resources for a single terminal.
[0142] In some embodiments, the network device sends configuration information to the terminal.
[0143] In some embodiments, the identification information includes a group Radio Network Temporary Identity (RNTI), which is used to address downlink control information (DCI) for scheduling shared CG resources.
[0144] In some embodiments, terms such as “group RNTI”, “public RNTI”, “shared RNTI”, and “specific RNTI” can be used to indicate multiple terminals used for addressing shared CG resources, and in some scenarios, the above terms can be used interchangeably.
[0145] In some embodiments, this group of RNTIs can be used for terminal addressing of CG Type 2 activation and / or deactivation of DCI, for addressing a group (or multiple terminals) of terminals using the shared CG resource.
[0146] In some embodiments, terminals that can use the same shared CG resource can be assigned to the same group RNTI.
[0147] In some embodiments, the aforementioned group RNTI can be configured for each CG resource. For example, the group RNTI corresponding to CG resource #1 is group RNTI#1, and the group RNTI corresponding to CG resource #2 is group RNTI#2.
[0148] For example, if the configuration information includes group RNTI#1 associated with shared CG resource #1, and UE#1 is configured with group RNTI#1, then UE#1 can identify the configuration information of CG resource #1 based on group RNTI#1, so that UE#1 can use CG resource #1 when there is a sudden surge in service.
[0149] In some embodiments, configuration information can be sent via Radio Resource Control (RRC) reconfiguration messages, RRC connection release messages, or system messages.
[0150] In some embodiments, the shared CG resource can be a CG resource used in the connected state or a CG resource used in the inactive state, such as a CG-SDT resource.
[0151] In some embodiments, the configuration information may also include one or more of the following: time-frequency domain resource configuration for shared CG resources, time alignment timer (TAT) configuration, Reference Signal Receiving Power (RSRP) threshold configuration, Orthogonal cover code (OCC) configuration, Physical Downlink Control Channel (PDCCH) configuration, Physical Downlink Shared Channel (PDSCH) configuration, Physical Uplink Shared Channel (PUSCH) configuration, Physical Uplink Control Channel (PUCCH) configuration, RNTI configuration, Logical Channel (LCH) restriction configuration, and receive window size configuration.
[0152] In some embodiments, both the RSRP threshold configuration and the TAT configuration are used to verify the validity of CG resources. For example, if the RSRP threshold is less than a certain threshold, the CG resource is valid. If the TAT timer does not time out, the CG resource is valid.
[0153] In some embodiments, the LCH restriction configuration is used to limit which LCHs can use the CG resource. The aforementioned RNTI configuration can be the addressing RNTI for the DCI receiving contention resolution messages. After the terminal transmits uplink through contention for the resource, it listens for this RNTI within the receive window to receive a response message. This RNTI can be calculated based on the location of the shared CG resource used by the UE in transmitting the uplink, for example, based on one or more of the time-domain, frequency-domain, code-domain, and spatial-domain locations of the shared CG resource.
[0154] Step S2102: The configuration information includes the configuration information of the group PDCCH, and the DCI for scheduling shared CG resources is sent through the group PDCCH.
[0155] In some embodiments, terms such as “group PDCCH”, “group common PDCCH”, and “common PDCCH” can all be used to indicate a PDCCH associated with a CG resource shared by multiple terminals. This PDCCH can be used to transmit DCIs that activate and / or deactivate the shared CG resource. In some scenarios, the above terms can be used interchangeably.
[0156] In some embodiments, the configuration information for the group PDCCH may include a Control Resource Set (CORESET) configuration. This allows the terminal to determine the resources occupied by the PDCCH in the frequency and time domains based on the CORESET configuration.
[0157] In some embodiments, the configuration information for the group PDCCH may also include search space configuration, such as the search space type, so that the terminal can determine on which resources to listen for and receive PDCCH. Search spaces are divided into public search spaces and UE-specific search spaces. The search space configuration information also includes the PDCCH monitoring occupancy, which determines when the UE begins listening for the PDCCH.
[0158] In some embodiments, the configuration information of the group PDCCH may also include the aggregation level of the PDCCH, the DCI format, etc.
[0159] In some embodiments, the terminal receives the DCI for scheduling shared CG resources via a group PDCCH.
[0160] Step S2103: Send uplink content via shared CG resources.
[0161] In some embodiments, if the terminal activates the shared CG resource through the DCI received by the group PDCCH and there is a burst of traffic in the terminal, then the shared CG resource can be used to send uplink content, such as uplink data or uplink request commands.
[0162] In some embodiments, the identification information also includes the identifier of the terminal.
[0163] In some embodiments, the UE identifier is used by the network device to uniquely identify the UE. For connected UEs, this UE identifier may be different from the UE's cell (C)RNTI.
[0164] In some embodiments, the UE identifier is shorter than the C-RNTI identifier, which can save signaling overhead.
[0165] In some embodiments, the terminal identifier is used to uniquely identify a terminal within a group; that is, the identifier is a group-specific UEID.
[0166] In some embodiments, the identifier of the terminal associated with a CG resource can be configured for each CG resource. For example, the same terminal UE#1 can use shared CG resource #1 and CG resource #2. Then, its identifier in the identifier information associated with CG resource #1 may be UE#11, while its identifier in the identifier information associated with CG resource #2 may be UE#21, and so on. This disclosure does not limit the specific implementation of the identifier of the terminal associated with CG resources.
[0167] In some embodiments, the uplink content sent by the terminal through shared CG resources includes the terminal's identifier, thereby assisting the network device in quickly and accurately determining which terminal sent the received uplink transmission.
[0168] In some embodiments, the terminal may carry the UE identifier assigned to the UE through the Media Access Control (MAC) control element (CE) or the MAC subheader.
[0169] In some embodiments, since the C-RNTI corresponding to a terminal can also uniquely identify a terminal, the terminal can also carry its corresponding C-RNTI when sending uplink content via shared CG resources, thereby assisting the network device in determining the terminal corresponding to the uplink content. This further saves resources used for configuring the identification information associated with shared CG resources for the terminal.
[0170] In some embodiments, the terminal deactivates the shared CG resource through the DCI received by the group PDCCH. The terminal can stop using the shared CG resource, for example, by stopping the use of the shared CG resource to send uplinks.
[0171] Step S2104: Send a contention resolution message via the PDCCH addressed by the group RNTI.
[0172] In some embodiments, after successfully receiving uplink content sent by the terminal, the network device can send a contention resolution message through the PDCCH addressed by the group RNTI to indicate to the terminal whether the uplink content it sent has been successfully received.
[0173] In some embodiments, the contention resolution message includes the identifier of the terminal associated with the shared CG resource as indicated in the configuration information.
[0174] In some embodiments, the UE ID can be carried via MAC CE or MAC subheader.
[0175] In some embodiments, if the contention resolution message supports multiple UE multiplexing, then the UE ID can be carried in the MAC subheader of the contention resolution MAC Protocol Data Unit (PDU).
[0176] In some embodiments, the terminal can receive contention resolution messages by listening to the PDCCH addressed by the group RNTI.
[0177] The communication method involved in the embodiments of this disclosure may include at least one of steps S2101 to S2104. For example, step S2101 may be implemented as a standalone embodiment, step S2101+S2102 may be implemented as a standalone embodiment, step S2101+S2103 may be implemented as a standalone embodiment, step S2101+S2104 may be implemented as a standalone embodiment, step S2101+S2102+S2103 may be implemented as a standalone embodiment, step S2101+S2103+S2104 may be implemented as a standalone embodiment, etc., but not limited thereto.
[0178] In the embodiments disclosed herein, some or all of the steps and their optional implementations may be arbitrarily combined with some or all of the steps in other embodiments, or may be arbitrarily combined with the optional implementations in other embodiments.
[0179] In the embodiments disclosed herein, each step and its optional implementation can also be carried out independently.
[0180] In this embodiment, the network device configures the terminal with the identification information associated with the shared CG resources, thereby providing conditions for the terminal to use the shared CG resources, reducing the latency of sudden services, improving the reliability of sudden services, and improving the utilization rate of shared resources.

[0197] In some embodiments, the method further includes: the network device receiving uplink content sent by the terminal through shared CG resources, wherein the uplink content includes the cell radio network temporary identifier (C-RNTI) corresponding to the terminal.

[0199] The communication method provided in this disclosure will be further described below with reference to the following embodiments.
[0200] The UE receives configuration information for shared CG resources sent by the network device, which includes identification information.
[0201] In some embodiments, the configuration information can be sent via an RRC reconfiguration message, an RRC connection release message, or a system message.
[0202] In some embodiments, the CG resource can be a CG Type 1 resource or a CG Type 2 resource. A UE can be configured with multiple shared CG resources.
[0203] In some embodiments, the CG resource can be a CG resource used in the connected state or a CG resource used in the inactive state (such as a CG-SDT resource).

Both RSRP threshold and TAT configurations are used to verify the validity of CG resources; for example, if the RSRP threshold is less than a certain threshold, the CG resource is valid. If the TAT timer has not expired, the pre-configured resource is valid. The LCH restriction configuration is used to limit which LCHs can use the CG resource. The RNTI configuration is the addressing RNTI for the DCI scheduling that receives contention resolution messages.
[0205] In some embodiments, after the UE transmits uplink data through contention for resources, it can listen for the RNTI within the receive window to receive a response message. The RNTI can be calculated based on the location of the CG resource used by the UE to transmit the uplink, such as calculating the RNTI based on the time domain / frequency domain / code domain / spatial domain location of the CG resource.

[0213] In some embodiments, the UE identifier is used by the network to identify the UE. For connected UEs, this UE identifier is different from the UE's C-RNTI identifier.
