Description

Technical Field

[0001] The present application relates to the field of communication technologies, and in particular to a method, device, and chip for sending uplink control information (UCI). Background Art

[0002] In 5G communication services, in order to improve resource utilization efficiency, terminal devices with different data transmission durations can reuse the same time-frequency physical resources. Among them, the terminal devices transmitting Ultra Reliable & Low Latency Communication (URLLC) services have a shorter transmission duration and are short time duration terminal devices; the terminal devices transmitting enhanced Mobile Broadband (eMBB) services have a longer transmission duration and are long time duration terminal devices. In the NR Rel-16 stage, when the time-frequency domain resources of the high priority (HP) uplink channel overlap with the time-frequency domain resources of the low priority (LP) uplink channel, and the UCI or data carried on the LP uplink channel can be multiplexed with the HP uplink channel, the LP uplink channel needs to be discarded and only one HP uplink channel is transmitted. However, in some cases, when the time-frequency domain resources of the LP uplink channel overlap with the time-frequency domain resources of the HP uplink channel, and the UCI carried on the LP uplink channel can be multiplexed with the HP uplink channel, the LP uplink channel will not be cancelled. Figure 1 As shown, when the UCI carried by the HP uplink channel is a Hybrid Automatic Repeat Request (HARQ)-Acknowledgement (ACK), the LP uplink channel can be multiplexed with the HP uplink channel, and the LP uplink channel will not be cancelled.

[0003] When the LP uplink channel can be multiplexed with the HP uplink channel and the LP uplink channel will not be cancelled, the terminal device receives the UCI indication, the time-frequency domain resources of the LP PUSCH overlap with the time-frequency domain resources to be cancelled indicated by the UCI, and when the LP PUSCH is applied to the time-frequency domain resources indicated by the UCI, the LP PUSCH will be cancelled, resulting in the HARQ-ACK carried by the HP uplink channel being unable to be transmitted.

[0036] In order to better understand the embodiments of the present application, the following professional terms involved in the embodiments of the present application are introduced:

[0037] (1) High-priority uplink channel and low-priority uplink channel

[0038] A high-priority uplink channel is a channel that carries high-priority services, and a low-priority uplink channel is a channel that carries low-priority services. An uplink channel can be a physical uplink control channel (PUCCH) or a physical uplink shared channel (PUSCH).

[0039] (2) Uplink Cancellation Indication (UL CI)

[0040] When two terminal devices send information on the same time-frequency domain resources, in order to ensure the successful transmission of information carried by the uplink channel of the high-priority service, the network device can send a UL CI to the terminal device corresponding to the low-priority uplink channel to suspend or cancel the transmission of the low-priority service. The UL CI indicates a time-frequency domain resource to be canceled (including time domain and frequency domain resources). The time domain resources to be canceled include time domain resources and frequency domain resources. The uplink cancellation indication UL CI includes frequency domain indication information, and the frequency domain resources for canceling the uplink transmission are determined according to the frequency domain indication information. The UL CI also includes time domain indication information, and the time domain resources for canceling the uplink transmission are determined according to the time domain indication information.

[0041] The embodiments of the present application provide a method, device, and chip for transmitting uplink control information (UCI), which facilitates the successful transmission of UCI carried by high-priority channels.

For example, the terminal device may also be a personal communication service (PCS) phone, a cordless phone, a session initiation protocol (SIP) phone, a wireless local loop (WLL) station, a personal digital assistant (PDA), etc. Common terminal devices include, for example, mobile phones, tablet computers, laptop computers, PDAs, mobile internet devices (MIDs), and wearable devices such as smart watches, smart bracelets, and pedometers, but the embodiments of the present application are not limited thereto.

[0046] The following further describes in detail a method for sending uplink control information UCI provided in an embodiment of the present application:

[0047] See Figure 2 , Figure 2 FIG. 1 is a flow chart of a method for sending uplink control information UCI provided in an embodiment of the present application. Figure 2 As shown, the uplink control information UCI sending method includes the following operations S201 to S202. Figure 2The method shown may be performed by a terminal device or a chip in the terminal device. The method for transmitting uplink control information UCI shown in other figures of the present invention is similar to the method shown in the figures, and will not be described in detail below.

[0048] S201. The terminal device cancels the transmission of the first low-priority LP uplink channel based on the uplink cancellation indication UL CI. The time domain resources to be canceled indicated by the ULCI overlap with the time domain resources of the first LP uplink channel, and the UL CI is applied to the corresponding priority of the first LP uplink channel. The time domain resources of the first LP uplink channel overlap with the time domain resources of the first high-priority HP uplink channel, and the first HP uplink channel carries the first UCI.

[0049] In one possible implementation, the first low-priority LP uplink channel may be LP PUSCH, and the first UCI may be HARQ-ACK. Optionally, the first UCI may also be HARQ-Negative Response (NACK), a channel status report (such as a precoding matrix indication PMI and a channel quality indication CQI), and a scheduling request. When the time domain resources to be canceled overlap with the time domain resources of the first LP uplink channel, and the UL CI is applied to the corresponding priority of the first LP uplink channel, and the first LP uplink channel overlaps with the time domain resources of the first high-priority HP uplink channel, the terminal device cancels the transmission of the first low-priority LP uplink channel based on the uplink cancellation indication UL CI (that is, the terminal device does not use the first low-priority LP uplink channel to send information).

[0050] like Figure 3 As shown, the first LP uplink channel is LP PUSCH, and the first HP uplink channel is HP PUCCH. DCI1 is used to schedule LP PUSCH, and DCI2 schedules HP PUCCH. The time domain resources of LP PUSCH and HP PUCCH overlap. HP PUCCH carries HARQ-ACK. If the terminal device receives UL CI, and the time domain resources to be canceled (shaded part) indicated by UL CI overlap with LPPUSCH, and UL CI is applied to low priority, the terminal device cancels LP PUSCH. The terminal device then sends the first UCI through the uplink channel.

[0051] S202. The terminal device sends a first UCI.

[0052] In a possible implementation, the uplink channel for sending the first UCI has the following three situations:

[0053] ① The terminal device sends the first UCI through the first HP uplink channel.

[0054] After the terminal device cancels the first low-priority LP uplink channel, the first high-priority HP uplink channel remains, and when the time-frequency resources of the first high-priority HP uplink channel do not overlap with the time-frequency resources of other uplink channels, the terminal device sends the first UCI through the first high-priority HP uplink channel. Figure 3 As shown, after the terminal device cancels the LP PUSCH, the remaining HP PUCCH is the time-frequency resource that does not overlap with other uplink channels. The terminal device sends HARQ-ACK through the HP PUCCH.

[0055] ② The terminal device sends the first UCI through the third LP uplink channel, and the time-frequency resources of the third LP uplink channel overlap with the time domain resources of the first HP uplink channel.

[0056] For a detailed description of the terminal device sending the first UCI through the third LP uplink channel, see Figure 9 Description in the corresponding embodiment.

[0057] ③ The terminal device sends the first UCI through the HP uplink channel other than the first HP uplink channel.

[0058] For a detailed description of the terminal device sending the first UCI through the HP uplink channel other than the first HP uplink channel, see Figure 10 Description in the corresponding embodiment.

[0059] Figure 2 In the illustrated embodiment, a terminal device cancels transmission of a first low-priority LP uplink channel based on an uplink cancellation indication (UL CI). The time domain resources of the first LP uplink channel overlap with those of a first high-priority HP uplink channel. When the first HP uplink channel carries first UCI, the time domain resources to be canceled indicated by the UL CI overlap with those of the first LP uplink channel, and the UL CI is applied to the corresponding priority of the first LP uplink channel. The terminal device then transmits the first UCI via the uplink channel. Before using the first LP uplink channel to transmit the first UCI, the first LP PUSCH is discarded, facilitating successful transmission of the UCI carried by the high-priority channel.

[0060] See Figure 4 , Figure 4 FIG. 1 is a flow chart of another method for sending uplink control information UCI provided in an embodiment of the present application. Figure 4 As shown, the uplink control information UCI sending method includes the following operations S401 to S403.

[0061] S401. Channel multiplexing is performed on information carried on LP uplink channels with overlapping time domain resources, wherein the uplink channels of the terminal device do not include HP uplink channels.

[0062] In one possible implementation, one or more HP uplink channels actually exist, and the terminal device assumes that the HP uplink channel does not exist. The terminal device determines which LP uplink channel's time-frequency domain resources to use for data transmission based on the resource type carried by the LP uplink channel with overlapping time-frequency resources. When the time-frequency resources of the LP uplink channel carrying SR overlap with the time-frequency resources of the LP uplink channel carrying CSI, SR is multiplexed to the LP uplink channel resources corresponding to CSI. When the time-frequency resources of the LP uplink channel carrying CSI / SR overlap with the time-frequency resources of a LP uplink channel carrying HARQ-ACK, it is determined whether it still belongs to the original HARQ-ACK PUCCH resource set based on the total bits of CSI and HARQ-ACK. If not, the PUCCH resource set containing the time-frequency resources of the LP uplink channel that should be used is determined based on the total bit range of UCI. For example Figure 5 As shown, the first low-priority LP uplink channel is LP PUSCH. When the time-frequency resources of LP PUSCH overlap with the time-frequency resources of LP PUCCH1, the terminal device determines to use the resource set where the time-frequency resources of LP PUSCH are located, and the terminal device cancels LP PUCCH1.

[0063] S402. The terminal device cancels the transmission of the first low-priority LP uplink channel based on the uplink cancellation indication UL CI. The time domain resources to be canceled indicated by the ULCI overlap with the time domain resources of the first LP uplink channel, and the UL CI is applied to the corresponding priority of the first LP uplink channel. The time domain resources of the first LP uplink channel overlap with the time domain resources of the first high-priority HP uplink channel, and the first HP uplink channel carries the first UCI.

[0064] For the step in which the terminal device cancels the transmission of the first low priority LP uplink channel based on the uplink cancellation indication UL CI, refer to the description of the step in which the terminal device cancels the transmission of the first low priority LP uplink channel based on the uplink cancellation indication UL CI in S201.

[0065] S403. The terminal device sends a first UCI.

[0066] In one possible implementation, the terminal device sends the first UCI through the first HP uplink channel. After the terminal device cancels the first low-priority LP uplink channel, the first high-priority HP uplink channel remains, and when the time-frequency resources of the first high-priority HP uplink channel do not overlap with the time-frequency resources of other uplink channels, the terminal device sends the first UCI through the first high-priority HP uplink channel. Figure 5 As shown, after the terminal device cancels the LP PUSCH, the HP PUCCH is left. The HP PUCCH does not overlap with the time-frequency resources of other uplink channels, and the terminal device sends HARQ-ACK through the HP PUCCH.

[0067] See Figure 6 , Figure 6 FIG. 1 is a flow chart of another method for sending uplink control information UCI provided in an embodiment of the present application. Figure 6 As shown, the uplink control information UCI sending method includes the following operations S601 to S604.

[0068] S601. Channel multiplexing is performed on information carried on LP uplink channels with overlapping time domain resources, wherein the uplink channels of the terminal device do not include HP uplink channels.

[0069] For the step of channel multiplexing the information carried on the LP uplink channel with overlapping time domain resources, refer to the description of the step of channel multiplexing the information carried on the LP uplink channel with overlapping time domain resources in S401. Figure 7 As shown, the LP uplink channel includes LP PUSCH, LP PUCCH1, and LP PUSCH2. Among them, the time domain resources of LP PUSCH overlap with the time domain resources of LP PUCCH1. The terminal device determines to use the PUCCH resource set where the time-frequency resources of LP PUSCH are located, and the terminal device cancels LP PUCCH1.

[0070] S602. If the time domain resources of the second LP uplink channel and the second HP uplink channel overlap in the uplink channel of the terminal device, and the UCI or data carried on the second LP uplink channel cannot be channel multiplexed with the second HP uplink channel, the terminal device cancels the transmission of the second LP uplink channel. The second LP uplink channel is different from the first LP uplink channel, and the second HP uplink channel is different from the first HP uplink channel.

[0071] In one possible implementation, after executing step S601, the terminal device performs channel multiplexing on the information carried on the LP uplink channels with overlapping time domain resources. Among the existing LP uplink channels, the LP uplink channel that overlaps with the time domain resources of the second HP uplink channel becomes the second LP uplink channel. If both the second LP uplink channel and the second HP uplink channel carry data, and both the second LP uplink channel and the second HP uplink channel are PUSCHs, since the two PUSCHs cannot overlap, the UCI or data carried on the second LP uplink channel cannot be channel multiplexed with the second HP uplink channel, and the terminal device cancels transmission of the second LP uplink channel.

[0072] like Figure 7After executing step S601, the existing LP uplink channels also include the first LP uplink channel, LP PUSCH, and LP PUSCH2. The second HP uplink channel is HP PUSCH1. The time domain resources of LP PUCCH2 overlap with the time domain resources of HP PUSCH1. LP PUCCH2 is the second LP uplink channel. UCI or data carried on HP PUCCH1 cannot be channel-multiplexed with LP PUSCH1. The terminal device cancels LP PUSCH2.

[0073] S603. The terminal device cancels the transmission of the first low-priority LP uplink channel based on the uplink cancellation indication UL CI. The time domain resources to be canceled indicated by the ULCI overlap with the time domain resources of the first LP uplink channel, and the UL CI is applied to the corresponding priority of the first LP uplink channel. The time domain resources of the first LP uplink channel overlap with the time domain resources of the first high-priority HP uplink channel, and the first HP uplink channel carries the first UCI.

[0074] For the step in which the terminal device cancels the transmission of the first low priority LP uplink channel based on the uplink cancellation indication UL CI, refer to the description of the step in which the terminal device cancels the transmission of the first low priority LP uplink channel based on the uplink cancellation indication UL CI in S201.

[0075] S604. The terminal device sends a first UCI.

[0076] In one possible implementation, the terminal device sends the first UCI through the first HP uplink channel. After the terminal device cancels the first low-priority LP uplink channel, the first high-priority HP uplink channel remains, and when the time-frequency resources of the first high-priority HP uplink channel do not overlap with the time-frequency resources of other uplink channels, the terminal device sends the first UCI through the first high-priority HP uplink channel. Figure 7 As shown, after the terminal device cancels the LP PUSCH, the HP PUCCH is left. The HP PUCCH does not overlap with the time-frequency resources of other uplink channels, and the terminal device sends HARQ-ACK through the HP PUCCH.

[0077] See Figure 8 , Figure 8 FIG. 1 is a flow chart of another method for sending uplink control information UCI provided in an embodiment of the present application. Figure 8 As shown, the uplink control information UCI sending method includes the following operations S801 to S805.

[0078] S801. Channel multiplexing is performed on information carried on LP uplink channels with overlapping time domain resources, wherein the uplink channels of the terminal device do not include HP uplink channels.

[0079] The step of performing channel multiplexing on information carried on LP uplink channels with overlapping time domain resources refers to the step of performing channel multiplexing on information carried on LP uplink channels with overlapping time domain resources in S601.

[0080] S802. If the time domain resources of the second LP uplink channel and the second HP uplink channel overlap in the uplink channel of the terminal device, and the UCI or data carried on the second LP uplink channel cannot be channel multiplexed with the second HP uplink channel, the terminal device cancels the transmission of the second LP uplink channel. The second LP uplink channel is different from the first LP uplink channel, and the second HP uplink channel is different from the first HP uplink channel.

[0081] For the step of S802, refer to the step description in step S602.

[0082] S803: Channel multiplexing is performed on information carried on HP uplink channels with overlapping time domain resources, wherein the uplink channels of the terminal device do not include LP uplink channels.

[0083] In one possible implementation, it is assumed that the uplink channel of the terminal device does not include the LP uplink channel. The terminal device determines which HP uplink channel's time-frequency domain resources to use for data transmission based on the resources carried by the overlapping HP uplink channel. When the time-frequency domain resources of the HP uplink channel carrying SR overlap with the time-frequency domain resources of the HP uplink channel carrying CSI, SR is multiplexed onto the resources of the HP uplink channel corresponding to the CSI. When the HP uplink channel carrying CSI / SR overlaps with an HP uplink channel carrying HARQ-ACK, it is determined whether it still belongs to the original HARQ-ACK PUCCH resource set based on the total bits of CSI and HARQ-ACK. If not, it is determined based on the total UCI bit range which HP uplink channel's time-frequency resources belong to the PUCCH resource set. If Figure 9 As shown, the first high-priority HP uplink channel is the HP PUCCH. When the HP PUCCH overlaps with the HP PUCCH2, the terminal device determines to use the PUCCH resource set where the time-frequency resources of the HP PUCCH are located, and the terminal device cancels the HP PUCCH2. Alternatively, the terminal device determines to use the PUCCH resource set where the time-frequency resources of the HP PUCCH2 are located, and the terminal device multiplexes the HARQ-ACK to the HP PUCCH2 and cancels the HP PUCCH.

[0084] S804. The terminal device cancels the transmission of the first low-priority LP uplink channel based on the uplink cancellation indication UL CI. The time domain resources to be canceled indicated by the ULCI overlap with the time domain resources of the first LP uplink channel, and the UL CI is applied to the corresponding priority of the first LP uplink channel. The time domain resources of the first LP uplink channel overlap with the time domain resources of the first high-priority HP uplink channel, and the first HP uplink channel carries the first UCI.

[0085] The step of the terminal device canceling the transmission of the first low priority LP uplink channel based on the uplink cancellation indication UL CI refers to the step S201.

[0086] S805. The terminal device sends a first UCI.

[0087] In one possible implementation, the terminal device sends the first UCI through the first HP uplink channel. After the terminal device cancels the LP PUSCH, the HP PUCCH remains. The HP PUCCH does not overlap with other HP uplink channels, and the terminal device sends HARQ-ACK through the HP PUCCH.

[0088] In one possible implementation, the terminal device sends the first UCI through the third LP uplink channel, and the time-frequency resources of the third LP uplink channel overlap with the time-domain resources of the first HP uplink channel. The third LP uplink channel is the LP uplink channel that has not been canceled in S801. After executing step S804, the time-frequency resources of the third LP uplink channel overlap with the time-domain resources of the first HP uplink channel. That is, the time-frequency resources of the third LP uplink channel do not overlap with the time-frequency resources of other LP uplink channels, but overlap with the first HP uplink channel. After executing step S804, the time-frequency resources of the first HP uplink channel do not overlap with the time-frequency resources of other HP uplink channels, and the terminal device multiplexes the first UCI carried by the first HP uplink channel to the third LP uplink channel, and uses the third LP uplink channel to send the first UCI. Figure 9 As shown, the third LP uplink channel is LP PUCCH2, which does not overlap with other LP uplink channels and is not cancelled in step S801. After the terminal device executes S804, the time domain resources of LP PUCCH2 overlap with those of HP PUCCH, and HP PUCCH sends HARQ-ACK through LP PUCCH2.

[0089] In a possible implementation, the terminal device sends the first UCI through an HP uplink channel other than the first HP uplink channel. The HP uplink channel existing after executing S803 includes: an HP uplink channel that overlaps with the first HP uplink channel and has not been cancelled. The terminal device sends the first UCI through the HP uplink channel. Figure 10As shown, when S803 is not executed, HP PUCCH, HP PUSCH1, and HP PUCCH overlap, and the terminal device multiplexes HARQ-ACK onto HP PUCCH2. The information carried by HP PUSCH is also multiplexed onto HP PUCCH2, canceling HP PUCCH and HP PUSCH1. After step S804 is executed, the existing HP uplink channels include HP PUCCH2, and the terminal device sends HARQ-ACK via HP PUCCH2.

[0090] It should be noted that the execution order of step S804 can be after S801 and before S802, that is: channel multiplexing is performed on the information carried on the LP uplink channel with overlapping time domain resources, wherein the uplink channel of the terminal device does not include the HP uplink channel; the terminal device cancels the transmission of the first low-priority LP uplink channel based on the uplink cancellation indication UL CI; if there is a second LP uplink channel in the uplink channel of the terminal device that overlaps with the time domain resources of the second HP uplink channel, and the UCI or data carried on the second LP uplink channel cannot be channel multiplexed with the second HP uplink channel, the terminal device cancels the transmission of the second LP uplink channel; channel multiplexing is performed on the information carried on the HP uplink channel with overlapping time domain resources, wherein the uplink channel of the terminal device does not include the LP uplink channel; the terminal device sends the first UCI.
