Abstract

Claims (41)

1 . A method, comprising:

determining, by a wireless communication node, an indication of a version of a sidelink transmission format, for configuring (i) a sidelink resource and (ii) at least one transmission configuration parameter for a sidelink transmission of a wireless communication device, by:

receiving, by a central unit of the wireless communication node, a mapping relationship table from an access and mobility management function (AMF), and a destination identifier from a wireless communication device; and

determining, by the central unit or a distribution unit of the wireless communication node, the indication using the mapping relationship table and the destination identifier; and

configuring, by the wireless communication node according to the indication of the version of the sidelink transmission format, (i) the sidelink resource and (ii) the at least one transmission configuration parameter for the sidelink transmission of the wireless communication device.

2 . The method of claim 1 , comprising determining the indication by receiving, by the wireless communication node, the indication from the wireless communication device.

3 . The method of claim 1 , comprising:

receiving, by the wireless communication node, at least one of the destination identifier and a cast type from the wireless communication device.

4 . The method of claim 1 , comprising determining the indication by:

sending, by the central unit to the distribution unit of the wireless communication node, the mapping relationship table and the destination identifier; and

determining, by the distribution unit, the indication using the mapping relationship table and the destination identifier.

5 . The method of claim 1 , comprising determining the indication by:

determining, by the central unit, the indication using the mapping relationship table and the destination identifier; and

sending, by the central unit to the distribution unit of the wireless communication node, the indication determined using the destination identifier.

6 . The method of claim 1 , comprising receiving, by the wireless communication node from a network entity, at least one of a mapping relationship table for a long term evolution (LTE) radio access technology (RAT) or a mapping relationship table for a new radio (NR) RAT.

7 . The method of claim 5 , further comprising sending, by the central unit to the distribution unit, the destination identifier.

8 . The method of claim 4 , comprising:

configuring, by the distribution unit according to the indication, the sidelink resource and the at least one transmission configuration parameter for the sidelink transmission of the wireless communication device.

9 . The method of claim 3 , wherein the mapping relationship table includes a mapping between the destination identifier and the indication.

10 . The method of claim 3 , wherein when the mapping relationship table is for a new radio (NR) RAT, the mapping relationship table is configured for sidelink broadcast, groupcast or unicast.

11 . A wireless communication node, comprising:

at least one processor configured to:

determine an indication of a version of a sidelink transmission format, to configure (i) a sidelink resource and (ii) at least one transmission configuration parameter for a sidelink transmission of a wireless communication device, by:

receiving, by a central unit of the wireless communication node, a mapping relationship table from an access and mobility management function (AMF), and a destination identifier from a wireless communication device; and

determining, by the central unit or a distribution unit of the wireless communication node, the indication using the mapping relationship table and the destination identifier; and

configure, according to the indication of the version of the sidelink transmission format, (i) the sidelink resource and (ii) the at least one transmission configuration parameter for the sidelink transmission of the wireless communication device.

12 . The wireless communication node of claim 11 , wherein the at least one processor is configured to determine the indication by receiving, via a receiver, the indication from the wireless communication device.

13 . The wireless communication node of claim 11 , wherein the at least one processor is configured to:

receive, via a receiver, at least one of the destination identifier and a cast type from the wireless communication device.

14 . The wireless communication node of claim 11 , wherein the at least one processor is configured to determine the indication by:

sending, via the central unit to the distribution unit of the wireless communication node, the mapping relationship table and the destination identifier; and

determining, via the distribution unit, the indication using the mapping relationship table and the destination identifier.

15 . The wireless communication node of claim 11 , wherein the at least one processor is configured to determine the indication by:

determining, via the central unit, the indication using the mapping relationship table and the destination identifier; and

sending, via the central unit to the distribution unit of the wireless communication node, the indication determined using the destination identifier.

16 . The wireless communication node of claim 11 , wherein the at least one processor is configured to receive, via a receiver from a network entity, at least one of a mapping relationship table for a long term evolution (LTE) radio access technology (RAT) or a mapping relationship table for a new radio (NR) RAT.

17 . The wireless communication node of claim 15 , wherein the at least one processor is configured to send, via the central unit to the distribution unit, the destination identifier.

18 . The wireless communication node of claim 14 , wherein the at least one processor is configured to:

configure, via the distribution unit according to the indication, the sidelink resource and the at least one transmission configuration parameter for the sidelink transmission of the wireless communication device.

19 . The wireless communication node of claim 13 , wherein the mapping relationship table includes a mapping between the destination identifier and the indication.

20 . The wireless communication node of claim 13 , wherein when the mapping relationship table is for a new radio (NR) RAT, the mapping relationship table is configured for sidelink broadcast, groupcast or unicast.
