Abstract

Claims (39)

1. A channel conflict processing method, comprising:

in response to a transmission resource of a high-priority uplink channel of a user equipment (UE) and a transmission resource of a low-priority uplink channel of the UE overlapping in time domain, determining a start symbol of the high-priority uplink channel is not earlier than an interval H after an end of a Physical Downlink Control Channel (PDCCH) corresponding to a Physical Downlink Shared Channel (PDSCH) corresponding to the high-priority uplink channel;

wherein the interval H is determined based on H1 and H2, H1 is N1 symbols defined in TS38.214, a value of H2 is 0, 1 or 2 symbols and H2 is determined according to processing capability reported by the UE; and

wherein the high-priority uplink channel is a hybrid automatic repeat request-acknowledgements physical uplink control channel (HARQ-ACK PUCCH).

2. The method according to claim 1 , further comprising:

in response to the transmission resource of the high-priority uplink channel of the UE, and the transmission resource of the low-priority uplink channel of the UE overlapping in time domain, determining a start position for transmission cancellation of the low-priority uplink channel; and

canceling the transmission resource of the low-priority uplink channel according to the start position for transmission cancellation.

3. The method according to claim 2 , wherein determining the start position for transmission cancellation of the low-priority uplink channel comprises one of:

determining a position that is a threshold interval after end of an end symbol of a channel corresponding to the high-priority uplink channel as the transmission cancellation start position;

and

determining a position that is a threshold interval before start of a start symbol of the high-priority uplink channel as the start position for transmission cancellation.

4. The method according to claim 3 , wherein the threshold interval comprises at least one of a time amount interval, or, an orthogonal frequency-division multiplexing (OFDM) symbol interval.

5. The method according to claim 3 , wherein the threshold interval comprises a first threshold interval and a second threshold interval, or the threshold interval comprises a first threshold interval.

6. The method according to claim 2 , wherein canceling the transmission resource on the low-priority uplink channel according to the start position for transmission cancellation comprises:

canceling the transmission resource on the low-priority uplink channel from the start position for transmission cancellation.

7. The method according to claim 1 , wherein the low-priority uplink channel comprises at least one of a dynamic PUSCH, a semi-persistent PUSCH, a HARQ-ACK PUCCH, an SR PUCCH, a channel state information physical uplink control channel (CSI PUCCH), an A-CSI PUSCH, an A-CSI PUCCH, a sounding reference signal (SRS), or a BFR PUCCH.

8. The method according to claim 2 , wherein in a case where the transmission resource on the high-priority uplink channel and the transmission resource on the low-priority uplink channel overlap in time domain, determining the start position for transmission cancellation of the low-priority uplink channel comprises:

in response to a transmission resource on the HARQ-ACK PUCCH and the transmission resource on the low-priority uplink channel overlapping in time domain, using a position that is a threshold interval after end an end symbol of a PDSCH corresponding to the HARQ-ACK PUCCH as the start position for transmission cancellation of the low-priority uplink channel.

9. The method according to claim 3 , wherein the threshold interval comprises at least one of a time amount interval, or, an orthogonal frequency-division multiplexing (OFDM) symbol interval.

10. The method according to claim 3 , wherein the threshold interval comprises a first threshold interval and a second threshold interval, or the threshold interval comprises a first threshold interval.

11. A device, comprising:

at least one processor; and

a memory configured to store at least one program,

wherein when executed by the at least one processor, the at least one program causes the at least one processor to perform operations, the operations comprising:

in response to a transmission resource of a high-priority uplink channel of a user equipment (UE) and a transmission resource of a low-priority uplink channel of the UE overlapping in time domain, determining a start symbol of the high-priority uplink channel is not earlier than an interval H after an end of a Physical Downlink Control Channel (PDCCH) corresponding to a Physical Downlink Shared Channel (PDSCH) corresponding to the high-priority uplink channel;

wherein the interval H is determined based on H1 and H2, H1 is N1 symbols defined in TS38.214, a value of H2 is 0, 1 or 2 symbols and H2 is determined according to processing capability reported by the UE; and

wherein the high-priority uplink channel is a hybrid automatic repeat request-acknowledgements physical uplink control channel (HARQ-ACK PUCCH).

12. The device according to claim 11 , the operations further comprise:

in response to the transmission resource on the high-priority uplink channel of the UE, and the transmission resource on the low-priority uplink channel of the UE overlapping in time domain, determining a start position for transmission cancellation of the low-priority uplink channel; and

canceling the transmission resource on the low-priority uplink channel according to the start position for transmission cancellation.

13. The device according to claim 12 , wherein determining the start position for transmission cancellation of the low-priority uplink channel comprises one of:

determining a position that is a threshold interval after end of an end symbol of a channel corresponding to the high-priority uplink channel as the transmission cancellation start position;

and

determining a position that is a threshold interval before start of a start symbol of the high-priority uplink channel as the start position for transmission cancellation.

14. The device according to claim 13 , wherein the threshold interval comprises at least one of a time amount interval, or, an orthogonal frequency-division multiplexing (OFDM) symbol interval.

15. A non-transitory computer-readable storage medium configured to store a computer program which, when executed by a processor, performs operations, the operations comprising:

in response to a transmission resource of a high-priority uplink channel of a user equipment (UE) and a transmission resource of a low-priority uplink channel of the UE overlapping in time domain, determining a start symbol of the high-priority uplink channel is not earlier than an interval H after an end of a Physical Downlink Control Channel (PDCCH) corresponding to a Physical Downlink Shared Channel (PDSCH) corresponding to the high-priority uplink channel;

wherein the interval H is determined based on H1 and H2, H1 is N1 symbols defined in TS38.214, a value of H2 is 0, 1 or 2 symbols and H2 is determined according to processing capability reported by the UE; and
