Abstract: A user equipment (UE) is configured to decode a system information block (SIB). The UE receives a first signal, wherein the first signal includes a first individual system information block (SIB) segment of a SIB, receives a second signal, wherein the second signal includes a second individual SIB segment of the SIB, reassembles the SIB using first SIB segment and the second SIB segment and decodes the contents of the SIB.

Abstract: Determining RRC processing delays for multi-subscriber identify module (MSIM) user equipments (UEs) may include decoding a capabilities message from a UE that indicates the UE is an MSIM UE that includes at least a first SIM and a second SIM. A communication for the first SIM of the UE may be encoded. The communication may be configured to cause the UE to perform a radio resource control (RRC) procedure. A transmission request received from the UE may be decoded. The transmission request may be associated with the RRC procedure. In response to receiving the transmission request, an uplink (UL) grant may be scheduled for the first SIM of the UE.

Abstract: This disclosure relates to techniques for performingrelay communication by a relay wireless device in a wireless communication system. A relay wireless device may receive bearer configuration information from a network. Based on the bearer configuration information, the UE may establish a bearer with a remote wireless device. The relay wireless device may forward data to/from the remote wireless device using the bearer.

Abstract: A first user equipment (UE) is capable of serving as a relay for a second UE using a sidelink connection. The first UE determines that a predetermined condition is satisfied, the predetermined condition associated with the first UE operating as a relay for a second UE, transmits a discovery message and monitors for a signal from the second UE in response to the discovery message.

IPC: H04W36/00

Abstract: Techniques are disclosed relating to handover between cellular base stations. In some embodiments that use dual-connectivity handover, disclosed techniques may facilitate synchronization of a security configuration switch. In some embodiments, the base station and/or mobile device determine activation sequence numbers for the security configuration switch (e.g., by estimating when a path switch will occur). In some embodiments, the security configuration switch is implicitly detected based in deciphering failure. In some embodiments, the security configuration switch is explicitly signaled and is checked based on deciphering failure. In some embodiments that use make before break handover techniques, a source base station may be retained after the path switch.

Abstract: This disclosure relates to techniques for quickly recovering from radio link failure in a wireless communication system. A wireless device may establish a wireless link with a cell. The wireless device may detect radio link failure for the wireless link. The wireless device may attempt to re-establish the wireless link using a previously provided wireless link configuration. If the cell accepts the attempt re-establish the wireless link using the previously provided wireless link configuration, the wireless link may be re-established in accordance with the previously provided wireless link configuration.

IPC: H04W76/15

Abstract: To accommodate a mix of high frequency carriers and lower frequency carriers, a protocol stack may include a radio link control (RLC) entity that allows configuration of status reporting control parameters on per carrier, or per subcarrier spacing. Alternatively, a protocol stack may include two RLC entities, one for handling high frequency carriers, and another for handling lower frequency carriers. High frequency carriers and lower frequency carriers may be distinguished based on a frequency threshold. Furthermore, a user equipment may transmit to the network an indication of its L2 buffer size. The network may configure the UE and/or control scheduling, to ensure the UE's L2 buffer does not overrun. Alternatively, the UE may indicate that it can support a percentage of a maximum buffer size. The network may configure the UE and/or control scheduling so that the UE's buffer occupancy does not exceed the percentage.
