Abstract: Apparatus, methods, and computer program products for relaying and side link communication are provided. An example method may include receiving, from a BS via a controlled discovery procedure, a query to verify a sidelink procedure with at least one UE. The example method may further include establishing, via the BS as a L2 relay, the sidelink procedure with the at least one UE. The example method may further include switching from the sidelink procedure to a sidelink PDCP procedure with a hybrid mode, the BS being an L2 relay for the sidelink PDCP procedure. The example method may further include transmitting to the at least one UE via the BS as the L2 relay, or receiving, from the at least one UE via the BS as an L2 relay, one or more PDCP PDUs corresponding to L2.

Abstract: Certain aspects provide a method for wireless communication. The method generally includes deriving a network specific identifier (NSI) in a network access identifier (NAI) format, the NSI including a network identifier (NID) stored at the UE, generating a subscription concealed identifier (SUCI) based on the NSI for authentication of the UE with a non-public network (NPN), and sending the SUCI to a network entity for the authentication of the UE with the NPN.

Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a user equipment (UE) may determine that handling of a protocol data unit (PDU) by the UE is preempted. The UE may transmit an indication that the preempted PDU is preempted. The indication may be generated by a physical layer of the UE, or by a MAC layer of the UE. The UE may receive information for a transmission of the preempted PDU. Numerous other aspects are provided.

Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a user equipment (UE) may receive a downlink data communication. The UE may determine a processing time for the downlink data communication based at least in part on at least one of: whether the downlink data communication was scheduled via preconfigured scheduling or via a downlink grant received in a downlink control channel, or whether the downlink data communication is an initial transmission or a retransmission. The UE may transmit acknowledgement or negative acknowledgement (ACK/NACK) feedback, corresponding to the downlink data communication, using a timing indicated by the processing time. Numerous other aspects are provided.

Abstract: A plurality of neutral host network (NHN) deployments may share a common evolved packet core (EPC). When a plurality of NHNs share a common EPC, continuity and mobility may be facilitated for a user equipment (UE) when the UE moves between NHNs (e.g., because the NHNs share a common EPC). Accordingly, a UE may perform a tracking area update (TAU) procedure when moving between NHNs that share a common EPC. However, a UE may need to discover whether two NHNs share a common EPC in order to perform a TAU procedure. If the UE discovers that, when moving between a first NHN and a second NHN, the NHNs do not sure a common EPC, the UE may perform an attach procedure.

Abstract: Detecting local cell identifier collision by a base station may be achieved by receiving, at a first base station from a user device, a dedicated identifier associated with a second base station. The dedicated identifier may include or otherwise map to a user device identifier associated with the second base station and a local cell identifier associated with the second base station. Based on the dedicated identifier, it may be determined, at the first base station, that there is a local cell identifier collision between the first base station and the second base station.

Abstract: The present disclosure presents a method and an apparatus for off-loading user equipment (UE) from a small cell base station. For example, the method may include identifying a first and a second set of UEs from a plurality of UEs at a small cell base station, prioritizing the first and the second set of UEs, and off-loading one or more UEs from the first or the second set of UEs based at least on the prioritization. As such, off-loading of UEs from a small cell base station may be achieved.
