Abstract:
PROBLEM TO BE SOLVED: To provide a method that enables attachment of cell relays to a wireless network.SOLUTION: During the attachment procedure, a relay eNB requests assignment of an identifier, or a portion thereof, from a donor eNB for subsequent packet routing to the relay eNB. Donor eNB can assign an identifier or portion thereof (or confirm/deny an explicit identifier request from the relay eNB) and can forward establishment information downstream to the relay eNB. Donor eNB, and intermediary relay eNBs if present, can store the identifier for subsequent use in routing packets to the relay eNB. The identifier can be a terminal endpoint identifier (TEID) utilized in a tunneling protocol, a relay identifier utilized in a relay protocol, and the like.
Abstract:
Certain aspects of the present disclosure relate to methods and apparatus for improving voice over new radio (VoNR)-to-voice over long term evolution (VoLTE). An example method generally includes communicating with and camping on a next generation node B (gNB) in a 5G new radio (NR) system; initiating a voice call with the gNB; receiving a 5G NR-to-long term evolution (LTE) handover command in response to initiating the voice call; performing a handover procedure in response to the handover command; detecting a failure in the handover procedure; and taking one or more actions in response to detecting the failure in the handover procedure.

Abstract:
The present disclosure presents a method and apparatus for dynamically configuring a cell update message at a user equipment (UE). For example the method may include determining that a size of the cell update message at the UE is above a threshold value after a 'measured results on random access channel (RACH)' information element (IE) is excluded from the cell update message. Furthermore such an example method may include removing one or more IEs from the cell update message until the size of the cell update message is at or below the threshold value. As such dynamic configuration of a cell update message at a UE is achieved.

Abstract:
Systems and methodologies are described that facilitate performing intra-cluster and inter-cluster reselection for relay eNBs. In intra-cluster reselection, a relay eNB can reselect a disparate relay eNB and indicate its identifier in a bearer list update message. The disparate relay eNB and upstream eNBs (including the donor eNB) can update routing tables based at least in part on the identifier. In addition, the relay eNB can provide identifiers of downstream relay eNBs to facilitate updating routing tables for those identifiers as well. In an inter-cluster reselection, relay eNBs can release connection to downstream relay eNBs and re-attach to a wireless network to receive an identifier from a new donor eNB in the new cluster. Alternatively, the relay eNB can request an identifier from the donor eNB during reselection, notify downstream relay eNBs of the reselection, and/or request identifiers for one or more downstream relay eNBs.
Abstract:
Systems and methodologies are described that facilitate packet routing among relay nodes in a wireless network. Bearer quality of service (QoS) mapping is provided for internet protocol (IP) relays by utilizing differentiated services (DiffServ) code point (DSCP) values to determine a bearer for communicating related packets. In addition, SDF filtering at a gateway node can be modified to route packets over certain tunnels to provide QoS for the packets.

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.
