Sidelink capability information transmission and security between peer terminals
Methods, systems, and devices related to digital wireless communication, and more specifically, to techniques related to transmitting sidelink capability and security information between peer terminals. In one exemplary aspect, a method for wireless communication includes transmitting, by the first terminal, capability information associated with the first terminal to the second terminal based on a triggering event, the capability information associated with the first terminal relating to a capability of the first terminal to directly communicate with a second terminal. In another exemplary aspect, a method for wireless communication includes receiving information associated with a first terminal from the first terminal, the capability information associated with the first terminal relating to a capability of the first terminal to directly communicate with the second terminal. The method also includes determining transmission parameters for unicast communication with the first terminal.
1. A method for wireless communication, comprising:
transmitting, by a first terminal, capability information associated with the first terminal to a second terminal, the capability information associated with the first terminal relating to a capability of the first terminal to directly communicate with a second terminal, so that the second terminal is configured to send the capability information associated with the first terminal received from the first terminal to a communication node, wherein the capability information associated with the first terminal is sent to the communication node via a sidelink terminal information message, and the capability information includes supported modulation and demodulation orders.
2. The method of claim 1 , wherein the first terminal transmits the capability information associated with the first terminal upon receiving a capability enquiry from the second terminal.
3. The method of claim 2 , wherein the capability enquiry includes a capability request filter.
4. The method of claim 1 , wherein the capability information includes an indication of supporting out-of-order delivery.
5. The method of claim 1 , wherein the capability information includes an indication of supporting radio link control (RLC) acknowledged mode (AM) SN.
6. The method of claim 1 , wherein the capability information includes an indication of supporting RLC unacknowledged mode (UM) SN.
7. An apparatus for wireless communication comprising a processor that is configured to carry out the method of claim 1 .
8. A non-transitory computer readable medium having code stored thereon, the code when executed by a processor, causing the processor to implement the method of claim 1 .
9. A method for wireless communication, comprising:
receiving, by a second terminal, capability information associated with a first terminal from the first terminal, the capability information associated with the first terminal relating to a capability of the first terminal to directly communicate with the second terminal; and
transmitting, by the second terminal, the capability information associated with the first terminal received from the first terminal to a communication node, wherein the capability information associated with the first terminal is sent to the communication node via a sidelink terminal information message
wherein the capability information includes supported modulation and demodulation orders.
10. The method of claim 9 , wherein the capability information includes an indication of supporting out-of-order delivery.
11. The method of claim 9 , wherein the capability information includes an indication of supporting radio link control (RLC) acknowledged mode (AM) SN.
12. The method of claim 9 , wherein the capability information includes an indication of supporting RLC unacknowledged mode (UM) SN.
13. An apparatus for wireless communication comprising a processor that is configured to carry out the method of claim 9 .
14. A non-transitory computer readable medium having code stored thereon, the code when executed by a processor, causing the processor to implement the method of claim 9 .
