Description

Technical Field

[0001] The embodiments of the present application relate to the field of communications, and more specifically, to a method, a terminal device, and a network device for wireless communications. Background Art

[0002] In the New Radio (NR) Release 15, in addition to the dynamically scheduled uplink resources, the network equipment also configures periodic uplink configuration grant (Configured Grant, CG) resources for each bandwidth part (Bandwidth Part, BWP) of each serving cell. For CG resources, the network equipment will configure a configuration grant timer (ConfiguredGrantTimer, CG Timer) for the terminal device through the configuration grant configuration (ConfiguredGrantConfig) in the radio resource control (RadioResource Control, RRC) signaling, and the value of the CG Timer is set to a multiple of the period of the CG resource.

[0003] Among them, during the operation of CGTimer, it is prohibited to use CG resources with the same HARQ process for initial data transmission to avoid overwriting the currently transmitted data in the HARQ buffer; in addition, when the CG Timer stops or times out, it implicitly indicates that the data transmitted by the corresponding HARQ process has been correctly received by the network.

[0004] A new timer, the CG retransmission timer, is introduced in NR Unlicensed. When the initial transmission of a transmission block (TB) of a HARQ process occurs on the CG resource, the CG retransmission timer will be started. When the CG retransmission timer times out, the terminal device can initiate an automatic retransmission on the CG resource, which means that the data has not been successfully received by the network. In the NR-U environment, since Listen Before Talk (LBT) may fail, the network device may not be able to give the terminal device a Hybrid Automatic Repeat Request (HARQ) feedback or dynamic scheduling. In order to mitigate the impact of LBT, the CG retransmission timer is conducive to ensuring the correct transmission of data on the NR-U CG resources.

[0005] However, since the CG Timer timeout and the CG retransmission timer timeout have different meanings, the CG retransmission timer is incompatible with the CG Timer. For example, when the transmission of a certain HARQ process occurs on a dynamic grant (DG) resource, if the CG Timer is started / restarted, automatic retransmission is not allowed on the CG resource, that is, there is no need to start the CG retransmission timer. Therefore, for the transmission of CG and DG resources, it is urgent to solve the technical problem of flexible coexistence of CG Timer and CG retransmission timer in NR-U.

[0006] In other words, how to ensure the correct transmission of data on NR-U CG resources while avoiding the overwriting of the currently transmitted data in the HARQ buffer is an urgent problem to be solved in this field. Summary of the invention

[0007] Provided are a wireless communication method, terminal device and network device, which can ensure the correct transmission of data on NR-U CG resources while avoiding the overwriting of currently transmitted data in the HARQ buffer.

[0008] In a first aspect, a wireless communication method is provided, comprising:

[0009] When sending the initial transmission data on the configured authorized CG resource, start or restart the first timer;

[0010] During the operation of the first timer, the terminal device is prohibited from using the target hybrid automatic repeat request HARQ process to send initial transmission data on the CG resources, and the terminal device is allowed to use the target HARQ process to retransmit the previously transmitted data on the CG resources. The target HARQ is a HARQ used to send initial transmission data on the CG resources, and the first timer is a timer used for the target HARQ process to send initial transmission data on the CG resources.

[0011] In a second aspect, a wireless communication method is provided, including:

[0012] Sending configuration information of the first timer to the terminal device;

[0013] During the operation of the first timer, the terminal device is prohibited from using the target hybrid automatic repeat request HARQ process to send initial transmission data on the CG resources, and the terminal device is allowed to use the target HARQ process to retransmit the previously transmitted data on the CG resources. The target HARQ is a HARQ used to send initial transmission data on the CG resources, and the first timer is a timer used for the target HARQ process to send initial transmission data on the CG resources.

[0014] In a third aspect, a terminal device is provided, which is used to execute the method in the first aspect or its implementations. Specifically, the terminal device includes a functional module for executing the method in the first aspect or its implementations.

[0015] In a fourth aspect, a network device is provided, which is used to execute the method in the second aspect or its respective implementations. Specifically, the network device includes a functional module used to execute the method in the second aspect or its respective implementations.

[0016] In a fifth aspect, a terminal device is provided, comprising a processor and a memory, wherein the memory is used to store a computer program, and the processor is used to call and run the computer program stored in the memory to execute the method in the first aspect or its implementation manners.

[0017] In a sixth aspect, a network device is provided, comprising a processor and a memory, wherein the memory is used to store a computer program, and the processor is used to call and run the computer program stored in the memory to execute the method in the second aspect or its implementation manners.

[0018] In a seventh aspect, a chip is provided for implementing the method in any one of the first to second aspects or their respective implementations. Specifically, the chip includes: a processor for calling and running a computer program from a memory, so that a device equipped with the chip executes the method in any one of the first to second aspects or their respective implementations.

[0019] In an eighth aspect, a computer-readable storage medium is provided for storing a computer program, wherein the computer program enables a computer to execute the method of any one of the first to second aspects or any of their implementations.

[0020] In a ninth aspect, a computer program product is provided, comprising computer program instructions, wherein the computer program instructions enable a computer to execute the method in any one of the first to second aspects above or in each of their implementations.

[0021] In a tenth aspect, a computer program is provided, which, when executed on a computer, enables the computer to execute the method in any one of the first to second aspects or in each of their implementations.

[0022] Based on the above technical solution, when the terminal device sends the initial transmission data on the CG resource, the first timer is started or restarted; since the first timer is a timer used for the target HARQ process to send the initial transmission data on the CG resource, and the terminal device is prohibited from using the target hybrid automatic repeat request HARQ process to send the initial transmission data on the CG resource in the running device of the first timer, it is possible to avoid the currently transmitted data in the HARQ buffer being overwritten by other initial transmission data.

[0023] In addition, since the terminal device is allowed to use the target HARQ process to retransmit the previously transmitted data on the CG resources within the running device of the first timer, the previously transmitted data can be retransmitted on the CG resources in combination with the CG retransmission timer even within the running device of the first timer, thereby ensuring the correct transmission of data on the NR-U CG resources.

[0024] To sum up, the wireless communication method of the present application can ensure the correct transmission of data on NR-U CG resources while avoiding the overwriting of the currently transmitted data in the HARQ buffer. BRIEF DESCRIPTION OF THE DRAWINGS

[0048] It should be understood that all devices with communication functions in the network / system in the embodiments of the present application can be referred to as communication devices.

[0049] It should be understood that the terms "system" and "network" are often used interchangeably in this article. The term "and / or" in this article is only a description of the association relationship of associated objects, indicating that three relationships can exist. For example, A and / or B can represent: A exists alone, A and B exist at the same time, and B exists alone. In addition, the character " / " in this article generally indicates that the associated objects before and after are in an "or" relationship.

[0050] Figure 2 A schematic flow chart of a wireless communication method 200 according to an embodiment of the present application is shown. The method 200 can be interactively executed by a terminal device and a network device. Figure 2 The terminal device shown in FIG. 1 may be a terminal device such as Figure 1 The terminal equipment shown, Figure 2 The network devices shown in can be Figure 1 The access network equipment shown.

[0051] See also Figure 2 , the method 200 includes some or all of the following contents:

[0052] S210, when the terminal device sends initial transmission data on the CG resource, it starts or restarts the first timer.

[0053] During the operation of the first timer, the terminal device is prohibited from using the target hybrid automatic repeat request HARQ process to send initial transmission data on the CG resources, and the terminal device is allowed to use the target HARQ process to retransmit the previously transmitted data on the CG resources. The target HARQ is a HARQ used to send initial transmission data on the CG resources, and the first timer is a timer used for the target HARQ process to send initial transmission data on the CG resources.

[0054] That is, the first timer is the timer for the HARQ process to send initial transmission data on the CG resource.

[0055] For example, when the terminal device uses the target HARQ to send initial transmission data on the CG resources, the first timer is started or restarted. In other words, when the initial transmission data of a certain HARQ process is transmitted on the CG resources, the first timer needs to be started. During the operation of the first timer, the CG resources with the same HARQ process cannot be used for initial transmission of data, but the CG resources with the same HARQ process can be used for retransmission of data. The initial transmission data may also be called initial transmission data, which refers to the data transmitted to the network device for the first time.

[0056] S240: If the first timer times out, it is determined that the network device has successfully received the initial transmission data sent by the terminal device using the target HARQ process. That is, when the first timer times out, it is assumed that the initial transmission data sent by the terminal device using the target HARQ process has been successfully received by the network device.

[0057] In other words, the expiration of the first timer can implicitly indicate that the network device has successfully received the initial transmission data sent by the terminal device using the target HARQ process.

[0058] Based on the above technical solution, when the terminal device sends the initial transmission data on the CG resource, the first timer is started or restarted; since the first timer is a timer used for the target HARQ process to send the initial transmission data on the CG resource, and the terminal device is prohibited from using the target hybrid automatic repeat request HARQ process to send the initial transmission data on the CG resource in the running device of the first timer, it is possible to avoid the currently transmitted data in the HARQ buffer being overwritten by other initial transmission data.

[0059] In addition, since the terminal device is allowed to use the target HARQ process to retransmit the previously transmitted data on the CG resources within the running device of the first timer, the previously transmitted data can be retransmitted on the CG resources in combination with the CG retransmission timer even within the running device of the first timer, thereby ensuring the correct transmission of data on the NR-U CG resources.

[0060] To sum up, the wireless communication method of the present application can ensure the correct transmission of data on NR-U CG resources while avoiding the overwriting of the currently transmitted data in the HARQ buffer.

[0061] It should be understood that the CG resources involved in this application include two types: Type 1 and Type 2. CG Type 1 can be configured by Radio Resource Control (RRC). For example, the terminal device can store the resources indicated by the RRC-ConfiguredUplinkGrant in the ConfiguredGrantConfig IE as uplink CG resources; CG Type 2 activates / deactivates uplink CG resources according to the Physical Downlink Control Channel (PDCCH) instruction scrambled by the ConfiguredScheduling Radio Network Temporary Identifier (CS-RNTI). For the same service cell, Type 1 or Type 2 CG resources can be configured for the Media Access Control (MAC) entity through RRC signaling.

[0062] It should also be understood that in the embodiment of the present application, the terminal device may be configured with multiple MAC entities, each of which may include one or more HARQ entities, each HARQ entity may correspond to a CG resource, and one HARQ entity may be used to maintain multiple parallel HARQ processes, and each HARQ process may correspond to an independent first timer. In a specific implementation, the HARQ entity in the terminal device may identify the HARQ process associated with the uplink authorization and perform initial transmission / retransmission of data according to the instruction.

[0063] It should also be understood that the sentence pattern "starting the timer at time A" involved in the embodiment of the present application only represents a trigger relationship, that is, the start or restart action of the timer is triggered by A, and should not be understood as a limitation on the present application. For example, for S210, it can be understood that the terminal device starts or restarts the first timer at the starting moment of sending the initial transmission data on the CG resource, and it can be understood that the terminal device starts or restarts the first timer at a certain time interval after the starting moment of sending the initial transmission data on the CG resource.

[0064] Figure 3 It is a schematic diagram of a method for wireless communication using a first timer according to an embodiment of the present application.

[0065] like Figure 3As shown, the terminal device uses HARQ process #0 to send the initial transmission data on the CG resource, and the timeout of the first timer means that the network device has successfully received the initial transmission data sent by the terminal device. Wherein, in the first timer running device, the terminal device can use the same HARQ process #0 as the initial transmission data to send the retransmission data of the initial transmission data on the CG resource.

[0066] In some embodiments of the present application, wireless communication may be performed by cooperating with the first timer through a second timer.

[0067] The duration of the second timer is less than the duration of the first timer, for example, the duration of the first timer is equal to an integer multiple of the duration of the second timer. During the operation of the second timer, the terminal device is prohibited from using the target HARQ process to send initial transmission data on the CG resource, and the terminal device is prohibited from using the target HARQ process to send retransmission data on the CG resource. The second timer is a timer used for the target HARQ process to automatically retransmit data on the CG resource.

[0068] In other words, the second timer can be a CG retransmission timer.

[0069] When the initial transmission / retransmission data of a certain HARQ process is transmitted on the CG resource, the second timer is started / restarted, and when the second timer times out, the CG resource with the same HARQ process can be used for data retransmission. For example, the CG resource with the same HARQ process is used to retransmit the data of the previous transmission.

[0070] At this time, if Figure 2 As shown, the method 200 may further include:

[0071] S220: Start or restart a second timer while starting or restarting the first timer.

[0072] S230: If the second timer times out, use the target HARQ process to retransmit the previously transmitted data on the CG resource; start or restart the second timer.

[0073] In other words, when the terminal device uses the target HARQ process to send initial transmission data on the CG resource, the first timer and the second timer can be started at the same time. If the second timer times out, the terminal device can use the target HARQ process to send retransmission data of the initial transmission data on the CG resource.

[0074] Figure 4 This is a schematic diagram of using the first timer and the second timer for wireless communication according to an embodiment of the present application.

[0075] like Figure 4 As shown, the terminal device uses HARQ process #0 to send initial transmission data on CG resources, and starts the first timer and the second timer. If the second timer times out, the terminal device can use the HARQ process #0 to retransmit the data of the previous transmission on the CG resources. For example, the retransmission data of the initial transmission data. The timeout of the first timer means that the network device has successfully received the initial transmission data sent by the terminal device using HARQ process #0 on the CG resources. Among them, in the first timer running device, the timeout of the second timer can be used to trigger the terminal device to retransmit the data of the previous transmission on the CG resources using HARQ process #0.

[0076] Of course, in other alternative embodiments, the terminal device can be triggered in other ways to send the retransmission data of the previous transmission on the CG resource using HARQ process #0 within the running device of the first timer.

[0077] For example, the terminal device may also use dynamic scheduling to cooperate with the first timer for wireless communication, which is not limited in this application.

[0078] Specifically, during the operation of the first timer, if the terminal device does not receive indication information for instructing the terminal device to retransmit the initial transmission data, it implicitly indicates that the network device has successfully received the initial transmission data sent by the terminal device. For another example, during the operation of the first timer, if the terminal device receives indication information for instructing the terminal device to retransmit the initial transmission data, the terminal device can send the retransmission data of the initial transmission data on the CG resource using the same HARQ as the initial transmission data.

[0079] In some embodiments of the present application, the terminal device may also perform wireless communication by using the initial transmission data and retransmission data transmitted on the DG resources by a timer.

[0080] In one implementation, the second timer is a timer used only for automatically retransmitting data by the target HARQ process on CG resources.

[0081] At this time, a special timer can be configured for the terminal device to be used for the target HARQ process to send initial transmission data or retransmission data on the DG resource.

[0082] For example, the terminal device may use the third timer to perform wireless communication on the DG resource. In other words, the third timer is used for the target HARQ process to send initial transmission data or retransmission data on the DG resource.

[0083] Among them, the duration of the third timer is smaller than the duration of the first timer. During the operation of the third timer, the terminal device is prohibited from using the target HARQ process to send initial transmission data on the CG resources, and the terminal device is prohibited from using the target HARQ process to send retransmission data on the CG resources.

[0084] When the target HARQ process receives the dynamically scheduled uplink DG authorization information and the initial transmission / retransmission occurs on the DG resources, the third timer is started / restarted. During the operation of the third timer, the target HARQ process cannot be used for initial data transmission on the CG resources, nor can the target HARQ process be used for data retransmission on the CG resources. When the third timer times out, it is assumed that the initial transmission data or retransmission data sent by the terminal device using the target HARQ process on the DG resources has been successfully received by the network device.

[0085] like Figure 2 As shown, the method 200 may further include:

[0086] S260, when the terminal device receives the dynamically scheduled authorized resources, it stops the first timer and the second timer, and starts or restarts the third timer.

[0087] S261, when the terminal device sends initial transmission data or retransmission data based on the scheduling information, the third timer is started or restarted.

[0088] S262: If the third timer times out, it is determined that the network device has successfully received the initial transmission data or retransmission data sent by the terminal device using the target HARQ process.

[0089] Thus, when the terminal device transmits on the CG resource, it can transmit the initial transmission data through the first timer, or it can transmit the initial transmission data and the retransmission data of the previous transmission through the first timer and the second timer. Furthermore, an additional third timer can be used to transmit the initial transmission data or retransmission data based on the scheduling information.

[0090] Figure 5 It is a schematic diagram of using the first timer, the second timer and the third timer to perform wireless communication according to an embodiment of the present application.

[0091] like Figure 5As shown, assuming that the initial transmission data TB1 of a certain HARQ process (for example, HARQ#0) occurs on the CG resource, since the start conditions of the first timer and the second timer are met at the same time, the first timer and the second timer are started at the same time. When the downlink feedback indication (DFI) or the scheduling information of the dynamic scheduling uplink authorization is not received, during the operation of the first timer, each time the second timer times out, HARQ#0 can be automatically triggered to automatically retransmit the retransmission data of the initial transmission data TB1 on the associated CG.

[0092] During the operation of the first timer, when the terminal device receives a dynamic scheduling grant, the first timer and the second timer are stopped, and the third timer is started at the same time. The terminal device may use the HARQ#0 to send the initial transmission data TB2 or the retransmission data of the initial transmission data TB1 on the resources indicated by the scheduling information.

[0093] When the initially transmitted data TB2 or the retransmitted data of the initially transmitted data TB1 is transmitted on the indicated dynamic resource, the third timer is restarted.

[0094] If the third timer times out, it can implicitly indicate that the initial transmission data TB2 or the retransmission data of the initial transmission data TB1 transmitted using HARQ#0 has been correctly received by the network device. At this time, the first timer, the second timer and the third timer are all in a non-running state.

[0095] It should be understood that the embodiments of the present application do not limit the specific duration of the timer.

[0096] For example, the duration of each timer can be set based on the data transmission and processing time. For example, the third timer can be set to the time interval of one data transmission and processing. During the operation of the third timer, the current transmission data can be prevented from being covered by the CG resources during the processing. The first timer can be set to the time interval of multiple data transmission and processing. During the operation of the first timer, the second timer can be used to control the corresponding HARQ process to use the CG resources for multiple automatic retransmissions.

[0097] Further, the duration of the second timer may be equal to the duration of the third timer.

[0098] In another implementation, the second timer is a timer for CG resources and DG resources.

[0099] In other words, the second timer can be reused for data transmitted on the DG resource, that is, there is no need to configure a dedicated timer for the DG resource.

[0100] At this time, the second timer may be a CG retransmission timer. When the initial transmission / retransmission data of a certain HARQ process is transmitted on the CG resource, the second timer is started / restarted. When the second timer times out, the CG resource with the same HARQ process may be used for data retransmission. For example, the retransmission data of the previous transmission is retransmitted using the CG resource with the same HARQ process.

[0101] At the same time, the second timer is also a timer for DG resources. When a certain HARQ process receives dynamically scheduled uplink DG authorization information and initial transmission / retransmission occurs on the DG resource, the second timer is started / restarted. During the operation of the second timer, the CG resource with the same HARQ process cannot be used for initial data transmission, nor can the CG resource with the same HARQ process be used for data retransmission. When the second timer times out, it is assumed that the data has been successfully received by the network device.

[0102] At this time, the method 200 may further include:

[0103] S250: When receiving the dynamically scheduled authorized resources, stop the first timer and start or restart the second timer.

[0104] S251, when sending initial transmission data or retransmission data based on the scheduling information, start or restart the second timer.

[0105] S252: If the second timer times out, it is determined that the network device has successfully received the initial transmission data or retransmission data sent by the terminal device using the target HARQ process.

[0106] Thus, when the terminal device transmits on the CG resource, it can transmit the initial transmission data through the first timer, or it can transmit the initial transmission data and the retransmission data of the previous transmission through the first timer and the second timer. Furthermore, the initial transmission data or retransmission data based on the scheduling information can be transmitted through the second timer.

[0107] Figure 6 This is a schematic diagram of using the first timer and the second timer for wireless communication according to an embodiment of the present application.

[0108] like Figure 6As shown, assuming that the initial transmission data TB1 of a certain HARQ process (for example, HARQ#0) occurs on the CG resource, since the start conditions of the first timer and the second timer are met at the same time, the first timer and the second timer are started at the same time. When the downlink feedback indication (DFI) or the scheduling information of the dynamic scheduling uplink authorization is not received, during the operation of the first timer, each time the second timer times out, HARQ#0 can be automatically triggered to automatically retransmit on the associated CG.

[0109] During the operation of the first timer, when the terminal device receives a dynamic scheduling grant, the first timer is stopped and the third timer is restarted. At this time, the terminal device can use the HARQ#0 to send the initial transmission data TB2 or the retransmission data of the initial transmission data TB1 on the resources indicated by the scheduling information.

[0110] When the initially transmitted data TB2 or the retransmitted data of the initially transmitted data TB1 is transmitted on the indicated dynamic resource, the second timer is restarted.

[0111] If the second timer times out, it can implicitly indicate that the initial transmission data TB2 or the retransmission data of the initial transmission data TB1 transmitted using HARQ#0 has been correctly received by the network device. At this time, both the first timer and the second timer are in a non-running state.

[0112] It should be understood that Figures 2 to 6 This is only an example of the present application and should not be construed as limiting the present application.

[0113] For example, in other alternative embodiments, the terminal device may execute steps S250 to S252 alone, or may execute steps S260 to S262 alone, or may execute S210 to S240 alone, and this application does not make any specific limitation on this.

[0114] The scheduling information of the embodiment of the present application is described below.

[0115] In some embodiments of the present application, the terminal device may send initial transmission data or retransmission data based on the scheduling information.

[0116] For example, the scheduling information includes a PDCCH scrambled with a CS-RNTI; at this time, the terminal device may send retransmission data on a CG resource indicated by the scheduling information. For example, the terminal device may send retransmission data on a CG resource indicated by the scheduling information using the above-mentioned target HARQ process.

[0117] For another example, the scheduling information includes a PDCCH scrambled by a cell radio network temporary identifier (Cell Radio Network Temporary Identifier, C-RNTI); at this time, if the CG resources and the DG resources indicated by the PDCCH do not overlap in the time domain, and the first timer and the second timer are both in a non-running state, the terminal device can use the target HARQ process to send initial transmission data on the CG resources; for example, if the physical uplink shared channel (Physical Uplink Shraed Channel, PUSCH) on the CG resources and the PUSCH on the DG resources indicated by the PDCCH do not overlap, and the first timer and the second timer are both in a non-running state, the terminal device can use the target HARQ process to send initial transmission data on the CG resources.

[0118] For another example, the scheduling information includes a PDCCH scrambled by using a C-RNTI; in this case, the terminal device may send the initial transmission data on the DG resource indicated by the scheduling information. For example, the terminal device may send the initial transmission data on the DG resource indicated by the scheduling information using the target HARQ.

[0119] In some embodiments of the present application, the method 200 may further include:

[0120] The terminal device receives at least one of the configuration information of the first timer, the configuration information of the second timer, and the configuration information of the third timer sent by the network device.

[0121] For example, the network device may carry at least two of the configuration information of the first timer, the configuration information of the second timer, and the configuration information of the third timer in the same message and send it to the terminal device.

The second timer is a timer for the target HARQ process to automatically retransmit data on the CG resources, or the second timer is a timer for the CG resources for retransmitting the previously transmitted data and the DG resources for sending initial transmission data or retransmission data.
