Abstract

Claims (51)

1. A scheduling request (SR) transmitting method, performed by a terminal, comprising:

switching to a second resource in a case that an SR fails to be transmitted at a first resource; and

transmitting the SR at the second resource;

wherein that the SR fails to be transmitted at the first resource comprises:

the SR fails to be transmitted at the first resource because there is other data with a higher priority than the SR in a physical layer multiplexing process;

wherein the switching to the second resource in the case that the SR fails to be transmitted at the first resource comprises:

triggering the SR and starting a timer; and

switching to the second resource in a case that the timer expires and the SR fails to be transmitted at the first resource.

2. The SR transmitting method according to claim 1 , wherein the second resource comprises: a target serving cell or a target bandwidth part (BWP) or a first SR configuration.

3. The SR transmitting method according to claim 2 , wherein the target serving cell comprises any one of:

a serving cell pre-configured by a network side, a serving cell selected by the terminal in accordance with a measurement result, a serving cell dynamically indicated by the network side, a serving cell in licensed spectrum, a special cell (SpCell) initially accessed by the terminal when entering a connected state, or an SpCell initially accessed by the terminal when adding a secondary network node;

wherein in a case that the target serving cell is the SpCell, the terminal switches from a secondary cell (SCell) to the SpCell.

4. The SR transmitting method according to claim 2 , wherein the target BWP comprises any one of:

a BWP pre-configured by a network side, a BWP selected by the terminal in accordance with a measurement result, a BWP dynamically indicated by the network side, a BWP in licensed spectrum, an initial BWP or a default BWP.

5. The SR transmitting method according to claim 2 , wherein the first SR configuration comprises: an SR configuration pre-configured by a network side or an SR configuration dynamically indicated by the network side.

6. The SR transmitting method according to claim 2 , wherein the transmitting the SR at the second resource comprises:

transmitting the SR in the target serving cell according to a second SR configuration; or

transmitting the SR in the target BWP according to a third SR configuration.

7. The SR transmitting method according to claim 6 , wherein the second SR configuration is an SR configuration selected for the target serving cell in accordance with an SR configuration corresponding to the first resource;

the third SR configuration is an SR configuration selected for the target BWP in accordance with the SR configuration corresponding to the first resource.

8. The SR transmitting method according to claim 2 , wherein the switching to the first SR configuration comprises:

switching from a current SR configuration to the first SR configuration, wherein the current SR configuration and the first SR configuration belong to a same serving cell or a same BWP.

9. The SR transmitting method according to claim 1 , further comprising:

performing counting by using a counter, wherein each time the terminal performs resource switching for the SR, the counter is incremented by 1, and the counter is initialized to 0 after the SR is triggered; and

triggering a random access procedure or a radio link failure (RLF) procedure when a count value of the counter reaches a threshold.

10. A non-transitory computer-readable storage medium storing therein a computer program, wherein the computer program is configured to be executed by a processor to implement steps in the method according to claim 1 .

11. A terminal, comprising: a transceiver, a memory, a processor, and a program stored in the memory and configured to be executed by the processor, wherein

the transceiver or the processor is configured to switch to a second resource in a case that an SR fails to be transmitted at a first resource; and

the transceiver is configured to transmit the SR at the second resource;

wherein that the SR fails to be transmitted at the first resource comprises:

the SR fails to be transmitted at the first resource because there is other data with a higher priority than the SR in a physical layer multiplexing process;

wherein the switching to the second resource in the case that the SR fails to be transmitted at the first resource comprises:

triggering the SR and starting a timer; and

switching to the second resource in a case that the timer expires and the SR fails to be transmitted at the first resource.

12. The terminal according to claim 11 , wherein the second resource comprises: a target serving cell or a target BWP or a first SR configuration.

13. The terminal according to claim 12 , wherein the target serving cell comprises any one of:

a serving cell pre-configured by a network side, a serving cell selected by the terminal in accordance with a measurement result, a serving cell dynamically indicated by the network side, a serving cell in licensed spectrum, a special cell (SpCell) initially accessed by the terminal when entering a connected state, or an SpCell initially accessed by the terminal when adding a secondary network node;

wherein in a case that the target serving cell is the SpCell, the terminal switches from a secondary cell (SCell) to the SpCell;

or

wherein the target BWP comprises any one of:

a BWP pre-configured by a network side, a BWP selected by the terminal in accordance with a measurement result, a BWP dynamically indicated by the network side, a BWP in licensed spectrum, an initial BWP or a default BWP;

or,

wherein the first SR configuration comprises: an SR configuration pre-configured by a network side or an SR configuration dynamically indicated by the network side.

14. The terminal according to claim 12 , wherein the transmitting the SR at the second resource comprises:

transmitting the SR in the target serving cell according to a second SR configuration; or

transmitting the SR in the target BWP according to a third SR configuration.

15. The terminal according to claim 12 , wherein the switching to the first SR configuration comprises:

switching from a current SR configuration to the first SR configuration, wherein the current SR configuration and the first SR configuration belong to a same serving cell or a same BWP.

16. The terminal according to claim 11 , wherein the transceiver or the processor is further configured to:

perform counting by using a counter, wherein each time the terminal performs resource switching for the SR, the counter is incremented by 1, and the counter is initialized to 0 after the SR is triggered; and

trigger a random access procedure or an RLF procedure when a count value of the counter reaches a threshold.
