Abstract

The present disclosure relates to scheduling methods for an ultra-wideband (UWB) and related products. One example method includes generating scheduling information and sending the scheduling information, where the scheduling information includes a time unit bitmap and a bitmap offset, the time unit bitmap indicates whether a time unit is used by a UWB device to transmit a UWB signal, the bitmap offset is used to determine a start time unit in which the UWB device transmits the UWB signal, and a time unit corresponding to a 1 st bit of the time unit bitmap is the start time unit.

First claim

1 . A scheduling method for an ultra-wideband (UWB), the method comprising:
generating scheduling information, wherein the scheduling information comprises a time unit bitmap and a bitmap offset, the time unit bitmap indicates whether a time unit is used by a UWB device to transmit a UWB signal, the bitmap offset is used to determine a start time unit in which the UWB device transmits the UWB signal, and a time unit corresponding to a 1 st bit of the time unit bitmap is the start time unit; and sending the scheduling information.

2 . The method according to claim 1 , wherein a value of the bitmap offset is a quantity of time units before the start time unit in one measurement period.

3 . The method according to claim 2 , wherein the time unit bitmap comprises K bits, K is an integer greater than 0, and when one of the K bits is set to a specified value, the specified value indicates that a time unit corresponding to the one of the K bits is used by the UWB device to transmit the UWB signal.

4 . The method according to claim 2 , wherein the measurement period is a ranging period.

5 . The method according to claim 1 , wherein the scheduling information further comprises a field indicating a length of the time unit bitmap.

6 . The method according to claim 1 , wherein the scheduling information further comprises an address of the UWB device, and a length of the address of the UWB device is 2 bytes or 8 bytes.

7 . The method according to claim 1 , wherein the time unit is a ranging scheduling time unit (RSTU).

8 . A communication apparatus, comprising at least one processor, wherein the at least one processor is coupled to at least one memory, the at least one memory stores computer program instructions which, when executed by the at least one processor, is configured to execute the computer program instructions, to cause the communication apparatus to:
generate scheduling information, wherein the scheduling information comprises a time unit bitmap and a bitmap offset, the time unit bitmap indicates whether a time unit is used by a UWB device to transmit a UWB signal, the bitmap offset is used to determine a start time unit in which the UWB device transmits the UWB signal, and a time unit corresponding to a 1 st bit of the time unit bitmap is the start time unit; and send the scheduling information.

9 . The communication apparatus according to claim 8 , wherein a value of the bitmap offset is a quantity of time units before the start time unit in one measurement period.

10 . The communication apparatus according to claim 9 , wherein the time unit bitmap comprises K bits, K is an integer greater than 0, and when one of the K bits is set to a specified value, the specified value indicates that a time unit corresponding to the one of the K bits is used by the UWB device to transmit the UWB signal.

11 . The communication apparatus according to claim 9 , wherein the measurement period is a ranging period.

12 . The communication apparatus according to claim 8 , wherein the scheduling information further comprises a field indicating a length of the time unit bitmap.

13 . The communication apparatus according to claim 8 , wherein the scheduling information further comprises an address of the UWB device, and a length of the address of the UWB device is 2 bytes or 8 bytes.

14 . The communication apparatus according to claim 8 , wherein the time unit is a ranging scheduling time unit (RSTU).

15 . A non-transitory computer-readable storage medium storing computer instructions which, when executed by at least one processor in a communication apparatus, cause the communication apparatus to:
generate scheduling information, wherein the scheduling information comprises a time unit bitmap and a bitmap offset, the time unit bitmap indicates whether a time unit is used by a UWB device to transmit a UWB signal, the bitmap offset is used to determine a start time unit in which the UWB device transmits the UWB signal, and a time unit corresponding to a 1 st bit of the time unit bitmap is the start time unit; and send the scheduling information.

16 . The non-transitory computer-readable storage medium according to claim 15 , wherein a value of the bitmap offset is a quantity of time units before the start time unit in one measurement period.

17 . The non-transitory computer-readable storage medium according to claim 16 , wherein the time unit bitmap comprises K bits, K is an integer greater than 0, and when one of the K bits is set to a specified value, the specified value indicates that a time unit corresponding to the one of the K bits is used by the UWB device to transmit the UWB signal.

18 . The non-transitory computer-readable storage medium according to claim 16 , wherein the measurement period is a ranging period.

19 . The non-transitory computer-readable storage medium according to claim 15 , wherein the scheduling information further comprises a field indicating a length of the time unit bitmap.

20 . The non-transitory computer-readable storage medium according to claim 15 , wherein the scheduling information further comprises an address of the UWB device, and a length of the address of the UWB device is 2 bytes or 8 bytes.
