Description

Uplink transmission method, uplink transmission indication method and equipment Technical Field

[0001] This disclosure relates to the field of communication technology, specifically to an uplink transmission method, an uplink transmission indication method, and an apparatus. Background Technology

[0002] Compared to previous mobile communication systems, fifth-generation (5G) mobile communication systems need to adapt to more diverse scenarios and service requirements. The main 5G scenarios include Enhanced Mobile Broadband (eMBB), Ultra-Reliable and Low-Latency Communications (URLLC), and Massive Machine-Type Communication (mMTC). These scenarios place demands on the system to achieve high reliability, low latency, high bandwidth, and wide coverage. For URLLC services, to meet the requirements of low latency and high reliability, symbol-level or mini-slot-level Physical Downlink Shared Channel (PDSCH), Physical Uplink Shared Channel (PUSCH), or Physical Uplink Control Channel (PUCCH) transmission is used.

[0003] For terminals that support multiple services simultaneously, there may be both low-priority and high-priority services. After the terminal receives the scheduling authorization for a PUSCH of a certain service, if a higher-priority service occurs, PUSCH transmission conflicts between different services may occur.

[0004] Summary of the Invention

[0005] This disclosure provides an uplink transmission method and device to resolve the problem of PUSCH transmission conflicts between different services.

[0006] In a first aspect, embodiments of this disclosure provide an uplink transmission method applied to a terminal, comprising:

[0007] Receive cancellation indication information corresponding to the first physical uplink shared channel (PUSCH) and scheduling authorization for the second PUSCH, wherein the priority of the first PUSCH is lower than the priority of the second PUSCH;

[0008] Based on the cancellation instruction information and the time domain location of the scheduling authorization, the corresponding terminal action is executed.

[0009] Secondly, embodiments of this disclosure also provide an uplink transmission indication method, applied to a network device, comprising:

[0010] Send cancellation indication information corresponding to the first PUSCH, wherein the time-frequency resources indicated by the cancellation indication information do not overlap with the time-frequency resources after multiplexing the first PUSCH and the second PUSCH; and / or, the time-frequency resources indicated by the cancellation indication information do not overlap with the time-frequency resources of the second PUSCH; wherein the priority level of the first PUSCH is lower than the priority of the second PUSCH.

[0011] Thirdly, embodiments of this disclosure also provide a terminal, including:

[0012] The receiving module is used to receive the cancellation indication information corresponding to the first PUSCH and the scheduling authorization of the second PUSCH, wherein the priority of the first PUSCH is lower than the priority of the second PUSCH.

[0013] The processing module is used to execute corresponding terminal actions based on the cancellation instruction information and the time domain location of the scheduling authorization.

[0014] Fourthly, embodiments of this disclosure also provide a network device, including:

[0015] The sending module is used to send cancellation indication information corresponding to the first PUSCH, wherein the time-frequency resources indicated by the cancellation indication information do not overlap with the time-frequency resources after multiplexing the first PUSCH and the second PUSCH; and / or, the time-frequency resources indicated by the cancellation indication information do not overlap with the time-frequency resources of the second PUSCH; wherein the priority level of the first PUSCH is lower than the priority of the second PUSCH.

[0016] Fifthly, embodiments of this disclosure also provide a communication device, including: a processor, a memory, and a program stored in the memory and executable on the processor, wherein when the program is executed by the processor, it implements the uplink transmission steps as described in the first aspect; or, the uplink transmission instruction steps as described in the second aspect.

[0017] In a sixth aspect, embodiments of this disclosure also provide a computer-readable storage medium storing a computer program that, when executed by a processor, implements the uplink transmission steps as described in the first aspect; or, the uplink transmission instruction steps as described in the second aspect.

[0018] In this embodiment of the disclosure, after the terminal receives the cancellation instruction information corresponding to the first PUSCH and the scheduling authorization of the second PUSCH, it performs corresponding terminal actions according to the time domain position of the cancellation instruction information and the scheduling authorization. This improves the terminal-side processing flow after receiving the scheduling authorization and cancellation instruction information of the high-priority PUSCH, and can ensure that the high-priority services of the terminal or other terminals in the network are processed first, effectively improving the timeliness and reliability of wireless communication system communication.

[0037] The embodiments of this disclosure are described below with reference to the accompanying drawings. The processing method and apparatus provided in this disclosure can be applied to a wireless communication system. Referring to Figure 1, a schematic diagram of the architecture of a wireless communication system provided in an embodiment of this disclosure is shown. As shown in Figure 1, the wireless communication system may include: a network device 10 and a terminal 11, which may be referred to as UE 11. The terminal 11 can communicate with the network device 10 (transmit signaling or transmit data). In practical applications, the connection between the above-mentioned devices can be a wireless connection. To facilitate a clear and intuitive representation of the connection relationship between the devices, solid lines are used in Figure 1.

[0038] The network device 10 provided in this embodiment can be a base station. The base station can be a commonly used base station, an evolved node base station (eNB), or a network device in a 5G system (e.g., a next-generation node base station (gNB) or a transmission and reception point (TRP)).

[0039] The terminal 11 provided in this embodiment can be a mobile phone, tablet computer, laptop computer, ultra-mobile personal computer (UMPC), netbook, personal digital assistant (PDA), mobile internet device (MID), wearable device, or vehicle-mounted device, etc.

[0040] Referring to Figure 2, this embodiment of the present disclosure provides an uplink transmission method. The execution subject of this method can be a terminal that supports multiple services, possibly including both low-priority and high-priority services. The specific steps are as follows:

[0041] Step 201: Receive the cancellation instruction information corresponding to the first PUSCH and the scheduling authorization of the second PUSCH, wherein the priority of the first PUSCH is lower than the priority of the second PUSCH;

[0042] In this embodiment, the second PUSCH corresponds to a high-priority PUSCH, and the first PUSCH corresponds to a low-priority PUSCH. It is understood that the priority of the PUSCH in this disclosure can be determined based on physical layer parameters, such as the downlink control information (DCI) for scheduling the PUSCH, or the physical layer parameters configured in the network.

[0043] For example, the terminal determines the service corresponding to the physical uplink channel to be transmitted based on the DCI sent by the network-side device. This DCI is the DCI corresponding to the physical uplink channel to be transmitted.

[0044] If the DCI format is a specific DCI payload size, or the DCI is scrambled using a specific Radio Network Temporary Identifier (RNTI), such as Modulation Coding Scheme-Cell-Radio Network Temporary Identifier (MCS-C-RNTI), or the priority indication field in the DCI indicates high priority, then the physical uplink channel to be transmitted corresponds to a high-priority PUSCH, such as URLLC services.

[0045] If the DCI format is not a specific DCI payload size, or the DCI does not use a specific RNTI scrambling, or the priority indicator field in the DCI indicates low priority, then the physical uplink channel to be transmitted corresponds to a low-priority PUSCH, such as eMBB service.

[0046] Optionally, the time-frequency resources indicated by the cancellation indicator (CI) information overlap with the time-frequency resources of the first PUSCH at least, wherein the cancellation indicator information may also be referred to as the cancellation indicator CI.

[0047] Step 202: Execute the corresponding terminal action based on the cancellation instruction information and the time domain location of the scheduling authorization.

[0048] In some implementations, the relationship between the time-domain positions of the cancellation instruction information and the scheduling authorization may include: (1) the time-domain position of the cancellation instruction information precedes the time-domain position of the scheduling authorization; (2) the time-domain position of the scheduling authorization precedes the time-domain position of the cancellation instruction information. Optionally, the terminal may perform different behaviors depending on the relationship between the time-domain positions of the cancellation instruction information and the scheduling authorization. The behavior performed by the terminal when it receives the scheduling authorization first and then the CI information may be inconsistent with the behavior when the terminal receives the CI information first and then the scheduling authorization.

[0049] In some implementations, the terminal behavior includes one of the following:

[0050] (1) Reuse the first PUSCH and the second PUSCH to ensure the processing of high-priority services of the terminal;

[0051] (2) If the time-frequency resources after the first PUSCH and the second PUSCH are multiplexed overlap with the time-frequency resources indicated by the cancellation indication information, the transmission on the time-frequency resources indicated by the cancellation indication information shall be cancelled. This can ensure the processing of high-priority services of other terminals in the network.

[0052] (3) Cancel the transmission of the first PUSCH. This will ensure the transmission of the second PUSCH of the terminal, that is, ensure the processing of the high-priority services of the terminal.

[0053] (4) If the time-frequency resources of the second PUSCH overlap with the time-frequency resources indicated by the cancellation indication information, the transmission of the first PUSCH and the second PUSCH will be cancelled. This will ensure the processing of high-priority services of other terminals in the network.

[0054] It is understandable that the cancellation of the second PUSCH transmission can be a partial transmission of the second PUSCH or a complete transmission of the second PUSCH. If the second PUSCH still has a demodulation reference signal (DMRS) in other locations besides the time-frequency resources indicated by the cancellation indication information, the terminal can still transmit the second PUSCH for other time-frequency resources besides the time-frequency resources indicated by the cancellation indication information.

[0055] In some implementations, before the step of receiving the cancellation indication information corresponding to the first PUSCH, the method further includes: receiving the PDCCH that schedules the first PUSCH; correspondingly, the step of receiving the cancellation indication information corresponding to the first PUSCH includes: receiving the cancellation indication information corresponding to the first PUSCH before the first PUSCH scheduled by the PDCCH is sent.

[0056] That is, the time for receiving the cancellation indication information corresponding to the first PUSCH and the scheduling authorization of the second PUSCH is: after receiving the PDCCH that schedules the first PUSCH and before sending the PUSCH scheduled by that PDCCH.

[0057] In some implementations, the step of executing corresponding terminal actions based on the cancellation instruction information and the time-domain location of the scheduling authorization includes:

[0058] If the time-domain position of the scheduling authorization is prior to the time-domain position of the cancellation indication information, the first PUSCH and the second PUSCH are reused. It is understood that, in this embodiment of the disclosure, the reuse of the first PUSCH and the second PUSCH can be performed using resource reuse rules in related technologies.

[0059] In some implementations, the time-domain position of the scheduling authorization preceding the time-domain position of the cancellation indication information means that the last symbol of the PDCCH receiving the scheduling authorization precedes the last symbol of the PDCCH receiving the cancellation indication information.

[0060] In some implementations, the step of performing the corresponding terminal action further includes:

[0061] If the reused time-frequency resources overlap with the time-frequency resources indicated by the cancellation instruction information, the transmission on the time-frequency resources indicated by the cancellation instruction information shall be cancelled.

[0062] Specifically, the transmission on the time-frequency resources that overlap with the multiplexed time-frequency resources indicated by the cancellation instruction information is cancelled.

[0063] Referring to Figure 3, the time-frequency resources indicated by the cancellation instruction partially overlap with the time-frequency resources of the low-priority PUSCH. The time-frequency resources of the low-priority PUSCH are multiplexed onto the time-frequency resources of the high-priority PUSCH, and the transmission of the multiplexed time-frequency resources is cancelled. This ensures the processing of high-priority services of other terminals in the network.

[0064] In some implementations, the step of executing corresponding terminal actions based on the cancellation instruction information and the time-domain location of the scheduling authorization includes:

[0065] If the time domain position of the cancellation instruction information is earlier than the time domain position of the scheduling authorization, perform one of the following terminal actions: (1) cancel the transmission of the first PUSCH; (2) cancel the transmission on the time-frequency resource indicated by the cancellation instruction information.

[0066] In some implementations, the time-domain position of the cancellation indication information preceding the time-domain position of the scheduling authorization means that the last symbol of the PDCCH receiving the scheduling authorization is after the last symbol of the PDCCH receiving the cancellation indication information.

[0067] In some implementations, the step of canceling the transmission of the first PUSCH includes:

[0068] If the time-frequency resources of the second PUSCH do not overlap with the time-frequency resources indicated by the cancellation indication information, the transmission of the first PUSCH is cancelled; or, if the time-frequency resources of the second PUSCH overlap with the time-frequency resources indicated by the cancellation indication information, the transmission of the first PUSCH is cancelled, and the transmission of the second PUSCH is performed. Cancelling the transmission of the first PUSCH may include: cancelling only the transmission of the first PUSCH on the overlapping resources, or cancelling the entire transmission of the first PUSCH. Performing the transmission of the second PUSCH includes: performing the transmission of the second PUSCH on the overlapping resources.

[0069] Referring to Figure 4, if the time-frequency resources indicated by the cancellation instruction overlap with the time-frequency resources of low-priority PUSCH but do not overlap with the time-frequency resources of high-priority PUSCH, then the transmission of low-priority PUSCH is cancelled and the transmission of high-priority PUSCH is performed. This ensures the transmission of high-priority PUSCH for the terminal.

[0070] Referring to Figure 5, if the time-frequency resources indicated by the cancellation instruction overlap with the time-frequency resources of low-priority PUSCH and overlap with the time-frequency resources of high-priority PUSCH, then only the transmission of low-priority PUSCH will be cancelled, and the transmission of high-priority PUSCH will not be cancelled. This ensures the transmission of high-priority PUSCH of the terminal.

[0071] In some implementations, the step of canceling the transmission on the time-frequency resource indicated by the cancellation instruction includes:

[0072] If the time-frequency resources of the second PUSCH overlap with the time-frequency resources indicated by the cancellation indication information, the transmission of both the first PUSCH and the second PUSCH is cancelled. Cancellation of the first PUSCH transmission may include: cancelling only the transmission of the first PUSCH on the overlapping resources, or cancelling all transmissions of the first PUSCH. Cancellation of the second PUSCH transmission may include: cancelling only the transmission of the second PUSCH on the overlapping resources, or cancelling all transmissions of the second PUSCH.

[0073] Referring to Figure 6, if the time-frequency resources indicated by the cancellation instruction overlap with the time-frequency resources of low-priority PUSCH and overlap with the time-frequency resources of high-priority PUSCH, then the transmission of low-priority PUSCH and high-priority PUSCH will be cancelled according to the cancellation instruction. This ensures the processing of high-priority services of other terminals in the network.

[0074] In some implementations, before or after step 201, the method shown in FIG2 further includes: receiving first information, the first information indicating whether the terminal cancels the transmission of the second PUSCH if the time-frequency resources of the second PUSCH of the terminal overlap with the time-frequency resources of the cancellation indication.

[0075] For example, the terminal receives the first information via Radio Resource Control (RRC) signaling.

[0076] For example, the first information includes an indicator bit: "1" indicates that the terminal cancels the transmission of the second PUSCH. "0" indicates that the terminal does not cancel the transmission of the second PUSCH. Of course, the content of the first information is not specifically limited in this embodiment of the disclosure.

[0077] For example, when the priority of the PUSCH of another terminal is higher than the priority of the second PUSCH of this terminal, the network side instructs the terminal to cancel the transmission of the second PUSCH through the first indication information, so as to ensure the transmission of the PUSCH of other terminals.

[0078] In some scenarios, a terminal that supports multiple services simultaneously may have both low-priority and high-priority services. In other scenarios, the high-priority services of other terminals in the network may have a higher priority than the high-priority services of this terminal. The above embodiments can ensure the processing of high-priority services.

[0079] In this embodiment of the disclosure, the processing flow after the terminal receives the scheduling authorization and cancellation indication information of the high-priority PUSCH is improved, which can ensure that high-priority services are processed first and effectively improve the timeliness and reliability of wireless communication system communication.

[0080] Referring to Figure 7, this embodiment of the present disclosure also provides a processing method, the execution subject of which is a network device, and the specific steps include:

[0081] Step 701: Send cancellation instruction information corresponding to the first PUSCH, wherein the time-frequency resources indicated by the cancellation instruction information do not overlap with the time-frequency resources multiplexed from the first PUSCH and the second PUSCH; and / or, the time-frequency resources indicated by the cancellation instruction information do not overlap with the time-frequency resources of the second PUSCH; wherein the priority level of the first PUSCH is lower than that of the second PUSCH, that is, the second PUSCH is equivalent to a high-priority PUSCH, and the first PUSCH is equivalent to a low-priority PUSCH. Alternatively, the time-frequency resources indicated by the cancellation instruction information may overlap with the time-frequency resources multiplexed from the first PUSCH and the second PUSCH; and / or, the time-frequency resources indicated by the cancellation instruction information may overlap with the time-frequency resources of the second PUSCH.

[0082] Optionally, the time-frequency resources indicated by the cancellation instruction information overlap with the time-frequency resources of the first PUSCH at least.

[0083] In an embodiment of the invention, the network side ensures the transmission of the terminal's second PUSCH by sending the cancellation instruction information, wherein the time-frequency resources indicated by the cancellation instruction information do not conflict with the time-frequency resources of the terminal's second PUSCH.

[0084] In some embodiments, before or after step 701, the method shown in FIG7 further includes:

[0085] A first message is sent to the terminal, indicating whether the terminal should cancel the transmission of the second PUSCH if the time-frequency resources of the terminal's second PUSCH overlap with the time-frequency resources indicated by the cancellation indication information. For example, the first message is sent to the terminal via RRC signaling.

[0086] For example, the first information includes an indicator bit: "1" indicates that the terminal cancels the transmission of the second PUSCH. "0" indicates that the terminal does not cancel the transmission of the second PUSCH. Of course, the content of the first information is not specifically limited in this embodiment of the disclosure.

[0087] For example, when the priority of the PUSCH of another terminal is higher than the priority of the second PUSCH of this terminal, the network side instructs the terminal to cancel the transmission of the second PUSCH through the first indication information, so as to ensure the transmission of the PUSCH of other terminals.

[0088] The following example illustrates the processing flow after the UE receives a high-priority PUSCH scheduling authorization and a DCI containing CI.

[0089] Example 1:

[0090] After a network device (e.g., a base station (gNB) schedules a PUSCH for an eMBB, a high-priority service arrives. For example, a high-priority service for the current UE might arrive first, followed by high-priority services for other UEs. If the current UE receives the scheduling authorization for the high-priority PUSCH first (i.e., the PDCCH receiving the cancellation indication is the last symbol), then the current UE first performs time-frequency resource multiplexing of its high-priority channel / signal with that of its low-priority channel / signal (e.g., multiplexing of UCI information). If the time-frequency resources of the multiplexed channel / signal still overlap with the time-frequency resources indicated by the CI, then either option A or B can be executed.

[0091] A: According to CI, the UE cancels the transmission of the multiplexed channel / signal (e.g., high-priority PUSCH). At this time, the UE considers CI to have higher priority, which can ensure the high-priority services of other UEs.

[0092] B: The UE does not expect the time-frequency resources indicated by CI to overlap with the multiplexed channels / signals (e.g., high-priority PUSCH), thus ensuring the transmission of the UE's high-priority PUSCH.

[0093] Referring to Figure 8, the time-frequency resources of eMBB PUSCH are multiplexed with the time-frequency resources of URLLC PUSCH. The time-frequency resources indicated by CI partially overlap with the multiplexed time-frequency resources. According to CI, the transmission of the multiplexed time-frequency resources is canceled (e.g., the transmission of URLLC PUSCH is canceled). This can ensure the high-priority services of other terminals in the network.

[0094] Example 2:

[0095] After the gNB schedules a PUSCH for an eMBB, a high-priority service arrives, for example, a high-priority service from another UE may arrive, and then another high-priority service from that UE arrives.

[0096] If the UE receives the high-priority PUSCH after the scheduling authorization, that is, the PDCCH that receives the high-priority PUSCH is the last symbol, execute C or D;

[0097] Wherein, C: If the time-frequency resources of the UE's high-priority PUSCH do not overlap with the time-frequency resources indicated by CI, then the UE cancels the transmission of the low-priority PUSCH and sends the high-priority PUSCH.

[0098] Referring to Figure 9, the time-frequency resources of URLLC PUSCH do not overlap with the time-frequency resources indicated by CI, so the transmission of eMBB PUSCH is cancelled and the transmission of URLLC PUSCH is performed.

[0099] D: If the time-frequency resources indicated by CI overlap with the time-frequency resources of the UE's high-priority PUSCH, or if the time-frequency resources indicated by CI overlap with the time-frequency resources of the eMBB PUSCH, then D1, D2, or D3 can be executed.

[0100] In D1: According to CI, the UE only cancels the transmission of low-priority PUSCH, and does not cancel the transmission of high-priority PUSCH.

[0101] D2: The UE cancels the transmission of low-priority PUSCH, and does not expect CI to overlap with its high-priority PUSCH.

[0102] D3: According to CI, the UE can cancel the transmission of low-priority and high-priority PUSCH. At this time, the UE considers CI to have higher priority.

[0103] Referring to Figure 10, the time-frequency resources of the URLLC PUSCH overlap with those indicated by the CI, thus canceling the transmission of the eMBB PUSCH. Alternatively, according to the CI, the transmission of both the URLLC PUSCH and the eMBB PUSCH can be canceled. In this case, the UE considers the CI to have a higher priority, which ensures that high-priority services of other terminals in the network are processed first.

[0104] Referring to Figure 11, this embodiment of the disclosure also provides a terminal, the terminal 1100 including:

[0105] The receiving module 1101 is used to receive the cancellation indication information corresponding to the first PUSCH and the scheduling authorization of the second PUSCH, wherein the priority of the first PUSCH is lower than the priority of the second PUSCH.

[0106] Wherein, the second PUSCH is equivalent to a high-priority PUSCH, and the first PUSCH is equivalent to a low-priority PUSCH. Optionally, the time-frequency resources indicated by the cancellation indication information overlap with the time-frequency resources of the first PUSCH at least.

[0107] The processing module 1102 is used to execute corresponding terminal actions based on the cancellation instruction information and the time domain location of the scheduling authorization.

[0108] In some embodiments, the receiving module 1101 is further configured to: receive the PDCCH that schedules the first PUSCH before receiving the cancellation indication information corresponding to the first PUSCH; and receive the cancellation indication information corresponding to the first PUSCH before sending the first PUSCH scheduled by the PDCCH.

[0109] That is, the time for receiving the cancellation indication information corresponding to the first PUSCH and the scheduling authorization of the second PUSCH is: after receiving the PDCCH that schedules the first PUSCH and before sending the PUSCH scheduled by that PDCCH.

[0110] In some implementations, the processing module 1102 is further configured to: reuse the first PUSCH and the second PUSCH if the time domain position of the scheduling authorization is prior to the time domain position of the cancellation indication information.

[0111] It is understood that the reuse of the first PUSCH and the second PUSCH in the embodiments of this disclosure can be performed using the resource reuse rules.

[0112] In some implementations, the time-domain position of the scheduling authorization preceding the time-domain position of the cancellation indication information means that the last symbol of the PDCCH receiving the scheduling authorization precedes the last symbol of the PDCCH receiving the cancellation indication information.

[0113] In some embodiments, the processing module 1102 is further configured to: cancel transmissions on the time-frequency resources indicated by the cancellation indication information when the time-frequency resources multiplexed by the first PUSCH and the second PUSCH overlap with the time-frequency resources indicated by the cancellation indication information. Specifically, it cancels transmissions on the time-frequency resources indicated by the cancellation indication information that overlap with the multiplexed time-frequency resources.

[0114] In some implementations, the processing module 1102 is further configured to: perform one of the following terminal actions when the time domain position of the cancellation indication information is before the time domain position of the scheduling authorization: (1) cancel the transmission of the first PUSCH; (2) cancel the transmission on the time-frequency resource indicated by the cancellation indication information.

[0115] In some implementations, the time-domain position of the cancellation indication information preceding the time-domain position of the scheduling authorization means that the last symbol of the PDCCH receiving the scheduling authorization is after the last symbol of the PDCCH receiving the cancellation indication information.

[0116] In some embodiments, the processing module 1102 is further configured to: cancel the transmission of the first PUSCH if the time-frequency resources of the second PUSCH do not overlap with the time-frequency resources indicated by the cancellation indication information; or, cancel the transmission of the first PUSCH and perform the transmission of the second PUSCH if the time-frequency resources of the second PUSCH overlap with the time-frequency resources indicated by the cancellation indication information.
