Abstract

Methods, systems, and devices are describe for signaling protocols for proximity service functions in a wireless communication system. A first wireless device may identify a group identity parameter associated with a multicast transmission of multimedia content. The first wireless device may map the identified group identity parameter to an identification parameter associated with at least one proximity service (ProSe) relay wireless device. The first wireless device may receive the multicast transmission of the multimedia content via the at least one ProSe relay wireless device based on the mapping of the identified group identity parameter to the identification parameter.

First claim

What is claimed is:

1 . A method for wireless communication, comprising:
identifying, by a first wireless device, a group identity parameter associated with a multicast transmission of multimedia content; mapping the identified group identity parameter to an identification parameter associated with at least one proximity service (ProSe) relay wireless device; and receiving the multicast transmission of the multimedia content via the at least one ProSe relay wireless device based on the mapping of the identified group identity parameter to the identification parameter.

2 . The method of claim 1 , further comprising:
receiving the multicast transmission of the multimedia content via the at least one ProSe relay wireless device using a PC5 reference point.

3 . The method of claim 1 , wherein the identification parameter associated with the at least one ProSe relay wireless device comprises a layer 2 (L2) identification of the at least one ProSe relay wireless device.

4 . The method of claim 1 , further comprising:
receiving a discovery message broadcast from the at least one ProSe relay wireless device; determining that the discovery message comprises an indication that the at least one ProSe relay wireless device supports the multicast transmission of multimedia content associated with the group identity parameter; and selecting the at least one ProSe relay wireless device to receive the multicast transmission of multimedia content.

5 . The method of claim 4 , wherein determining that the discovery message comprises the indication, comprises:
determining that the discovery message comprises the group identity parameter.

6 . The method of claim 1 , further comprising:
receiving a plurality of discovery messages broadcast from a plurality of ProSe relay wireless devices; determining that the plurality of discovery messages broadcast from the plurality of ProSe relay wireless devices fail to include an indication that the plurality of ProSe relay wireless devices support the multicast transmission of multimedia content associated with the group identity parameter; and sending a request message via a first ProSe relay wireless device in response to the determining, the request message requesting support of the multicast transmission of multimedia content associated with the group identity parameter.

7 . The method of claim 6 , further comprising:
determining that a subsequent discovery message broadcast from the at least one ProSe relay wireless device comprises an indication that the at least one ProSe relay wireless device supports the multicast transmission of multimedia content associated with the group identity parameter; and selecting the at least one ProSe relay wireless device to receive the multicast transmission of multimedia content.

8 . The method of claim 6 , wherein the request message comprises at least a message type parameter, or a command parameter, or a group identity parameter listing, or an integrity protection parameter, or a combination thereof.

9 . The method of claim 6 , wherein the at least one ProSe relay wireless device is the first ProSe relay wireless device.

10 . The method of claim 1 , further comprising:
sending a temporary mobile group identity (TMGI) monitor request that comprises the group identification parameter.

11 . The method of claim 10 , further comprising:
receiving a response from a first ProSe relay wireless device, wherein the response comprises the group identification parameter and an indication that the multimedia content is available.

12 . The method of claim 1 , further comprising:
initiating a ProSe protocol between the first wireless device and the at least one ProSe relay wireless device prior to an initiation of a communication data exchange between the first wireless device and the at least one ProSe relay wireless device.

13 . An apparatus for wireless communication, comprising:
a processor; memory in electronic communication with the processor; and instructions stored in the memory, the instructions being executable by the processor to: identify, by a first wireless device, a group identity parameter associated with a multicast transmission of multimedia content; map the identified group identity parameter to an identification parameter associated with at least one proximity service (ProSe) relay wireless device; and receive the multicast transmission of the multimedia content via the at least one ProSe relay wireless device based on the mapping of the identified group identity parameter to the identification parameter.

14 . The apparatus of claim 13 , further comprising instructions executable by the processor to:
receive the multicast transmission of the multimedia content via the at least one ProSe relay wireless device using a PC5 reference point.

15 . The apparatus of claim 13 , wherein the identification parameter associated with the at least one ProSe relay wireless device comprises a layer 2 (L2) identification of the at least one ProSe relay wireless device.

16 . The apparatus of claim 13 , further comprising instructions executable by the processor to:
receive a discovery message broadcast from the at least one ProSe relay wireless device; determine that the discovery message comprises an indication that the at least one ProSe relay wireless device supports the multicast transmission of multimedia content associated with the group identity parameter; and select the at least one ProSe relay wireless device to receive the multicast transmission of multimedia content.

17 . The apparatus of claim 16 , wherein the instructions to determine that the discovery message comprises the indication are further executable by the processor to:
determine that the discovery message comprises the group identity parameter.

18 . The apparatus of claim 13 , further comprising instructions executable by the processor to:
receive a plurality of discovery messages broadcast from a plurality of ProSe relay wireless devices; determine that the plurality of discovery messages broadcast from the plurality of ProSe relay wireless devices fail to include an indication that the plurality of ProSe relay wireless devices support the multicast transmission of multimedia content associated with the group identity parameter; and send a request message via a first ProSe relay wireless device in response to the determining, the request message requesting support of the multicast transmission of multimedia content associated with the group identity parameter.

19 . The apparatus of claim 18 , further comprising instructions executable by the processor to:
determine that a subsequent discovery message broadcast from the at least one ProSe relay wireless device comprises an indication that the at least one ProSe relay wireless device supports the multicast transmission of multimedia content associated with the group identity parameter; and select the at least one ProSe relay wireless device to receive the multicast transmission of multimedia content.

20 . The apparatus of claim 18 , wherein the request message comprises at least a message type parameter, or a command parameter, or a group identity parameter listing, or an integrity protection parameter, or a combination thereof.

21 . The apparatus of claim 18 , wherein the at least one ProSe relay wireless device is the first ProSe relay wireless device.

22 . The apparatus of claim 13 , further comprising instru
