Uplink channel sending method and apparatus

1. A method, comprising:

determining, by a terminal, that a resource of a first uplink channel carries a reference signal for demodulating the first uplink channel and that a resource of a second uplink channel does not carry a reference signal for demodulating the second uplink channel;

based on the resource of the first uplink channel carrying a reference signal for demodulating the first uplink channel and based on the resource of the second uplink channel not carrying a reference signal for demodulating the second uplink channel, determining, by the terminal, that a priority of the first uplink channel is higher than a priority of the second uplink channel wherein the resource of the first uplink channel overlaps with the resource of the second uplink channel in terms of time; and

based on determining that the priority of the first uplink channel is higher than the priority of the second uplink channel, preferentially allocating, by the terminal, transmission power to the first uplink channel.

2. The method according to claim 1 , wherein preferentially allocating transmission power to the first uplink channel comprises:

allocating, by the terminal, transmission power to the first uplink channel; and

cancelling, by the terminal, sending of the second uplink channel.

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

determining, by the terminal, a transmission power of the first uplink channel, wherein the first uplink channel is on a first time domain resource corresponding to a first duration; and

sending, by the terminal, the first uplink channel at the transmission power.

4. The method according to claim 3 , wherein the first duration is less than or equal to 0.5 ms.

5. An apparatus, comprising:

a non-transitory computer-readable memory having processor-executable instructions stored thereon; and

at least one processor coupled to the non-transitory computer-readable memory, wherein the at least one processor is configured to execute the processor-executable instructions to:

determine that a resource of a first uplink channel carries a reference signal for demodulating the first uplink channel and that a resource of a second uplink channel does not carry a reference signal for demodulating the second uplink channel;

based on the resource of the first uplink channel carrying a reference signal for demodulating the first uplink channel and based on the resource of the second uplink channel not carrying a reference signal for demodulating the second uplink channel, determine that a priority of the first uplink channel is higher than a priority of the second uplink channel, wherein the resource of the first uplink channel overlaps with the resource of the second uplink channel in terms of time; and

based on determining that the priority of the first uplink channel is higher than the priority of the second uplink channel, preferentially allocate transmission power to the first uplink channel.

6. The apparatus according to claim 5 , wherein preferentially allocating transmission power to the first uplink channel comprises:

allocating transmission power to the first uplink channel; and

cancelling sending of the second uplink channel.

7. The apparatus according to claim 5 , wherein the at least one processor is further configured to execute the processor-executable instructions to:

determine a transmission power of the first uplink channel, wherein the first uplink channel is one of at least one uplink channel on a first time domain resource corresponding to a first duration; and

send the first uplink channel at the transmission power.

8. The apparatus according to claim 7 , wherein the first duration is less than or equal to 0.5 ms.

9. A non-transitory computer-readable storage medium having processor-executable instructions stored thereon, wherein the processor-executable instructions, when executed by a terminal, facilitate:

determining that a resource of a first uplink channel carries a reference signal for demodulating the first uplink channel and that a resource of a second uplink channel does not carry a reference signal for demodulating the second uplink channel;

based on the resource of the first uplink channel carrying a reference signal for demodulating the first uplink channel and based on the resource of the second uplink channel not carrying a reference signal for demodulating the second uplink channel, determining a priority of the first uplink channel is higher than a priority of the second uplink channel, wherein the resource of the first uplink channel overlaps with the resource of the second uplink channel in terms of time; and

based on determining that the priority of the first uplink channel is higher than the priority of the second uplink channel, preferentially allocating transmission power to the first uplink channel.

10. The non-transitory computer-readable storage medium according to claim 9 , wherein preferentially allocating transmission power to the first uplink channel comprises:

allocating transmission power to the first uplink channel; and

cancelling sending of the second uplink channel.

11. The non-transitory computer-readable storage medium according to claim 9 , wherein the processor-executable instructions, when executed by the terminal, further facilitate:

determining, by the terminal, a transmission power of the first uplink channel, wherein the first uplink channel is one of at least one uplink channel on a first time domain resource corresponding to a first duration; and

sending the first uplink channel at the first transmission power.

12. The non-transitory computer-readable storage medium according to claim 11 , wherein the first duration is less than or equal to 0.5 ms.
