Abstract
Systems and methodologies are described that facilitate compressing packet headers for cell relay communications. Since cell relays can support a number of evolved packet system (EPS) bearers over a given dedicated radio bearer (DRB), robust header compression (RoHC) can be multiplexed for communications to/from a given cell relay. Thus, an upstream node compressing one or more packet headers can indicate a RoHC context, which can be represented by a RoHC context identifier in a RoHC header. A receiving entity can decompress the headers based on determining the RoHC context. Alternatively, the RoHC context can be associated with an identifier of a related UE bearer such as a tunnel endpoint identifier (TEID), a relay identifier, and/or the like, that is received in a tunneling protocol header to facilitate packet routing.
