1. An apparatus, comprising:
- at least one processor coupled to memory, wherein the at least one processor is configured to;
receive a message indicating that a common network transceiver has entered a stand-alone mode, wherein communication facilitated by the common network transceiver is enabled only between relay stations and/or mobile stations associated with the common network transceiver;
identify first security information associated with an uplink (UL) to at least one antenna of the common network transceiver;
transmit an UL communication to the at least one antenna of the common network transceiver, wherein the UL communication comprises an UL service data unit (SDU) using the first security information;
wherein the common network transceiver is configured to send, via the at least one antenna, a downlink (DL) communication to a second mobile station using second security information associated with the DL of the second mobile station of a plurality of mobile stations, wherein the DL communication comprises a DL SDU corresponding to the UL SDU.

Abstract
Methods and systems for providing efficient communications between two mobile stations served by the same base station or relay station are provided. A base station maintains information identifying which mobile stations it is serving. When a connection is set up between two mobile stations, if they are both being served by the same base station, the base station forwards traffic directly between the two mobile stations without forwarding it on to higher level network entities.
