Abstract: Systems, apparatuses, and methods for notification support in extended discontinuous reception mode. A base station and UE may configure eDRX communication. An indication may be received during the eDRX communication. The network may cache the indication. The network may modify the DRX configuration. The network may use a wake up signal. In response, the UE may receive the indication while achieving power savings from the eDRX configuration.

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.

Abstract: A user equipment (UE) is configured to communicate with a further UE via a sidelink (SL). The UE encodes traffic for transmission to the further UE, wherein the traffic comprises a payload and a medium access control (MAC) subheader, wherein the MAC subheader indicates whether the payload corresponds to non-routed traffic between the UE and the further UE or routed traffic between either one of the UE or the further UE and a base station, wherein an other one of the UE or the further UE functions as a relay for the routed traffic and transmits the traffic.

Abstract: A user equipment (UE) configured as a relay UE between a remote UE and a base station is disclosed. The UE comprises one or more processors configured to receive a RRC signaling to request for establishing or resuming RRC connection from the remote UE, determine whether to perform an access control check prior to forwarding the RRC Signaling of the remote UE to the base station, and forward the RRC Signaling to the base station based on the determination.

Abstract: This disclosure relates to performing implicit radio resource control state transitions in a cellular communication system. A wireless device may establish a radio resource control (RRC) connection with a cellular base station. A data inactivity timer length and a target RRC state for implicit RRC transitions may be determined. A data inactivity timer having the determined data inactivity timer length may be initiated. It may be determined that the data inactivity timer has expired. The wireless device may transition to the target RRC state based at least in part on determining that the data inactivity timer has expired.

Abstract: Apparatuses, systems, and methods for PDCCH enhancements for group-based paging indications. A user equipment device may be configured to receive, from a network, an indication of a paging occasion via a PG-RNTI and/or via at least 6 bits of a DCI. A value of the PG-RNTI may be associated with the paging occasion as well as a set of UEs, including the UE. The UE may be configured to monitor the paging occasion based on the value of the PG-RNTI and receive, during the paging occasion, a paging indication via at least six bits of a DCI, where each bit of the at least six bits may indicate a paging indication for a particular set of UEs and the particular set of UEs may be a subset of the set of UEs. The UE may also be configured to, in response to determining that the UE has a paging message, decode a corresponding PDSCH.

Abstract: Methods and systems are disclosed for a UE of a wireless communication network to recover from MCG radio link failures in a MR-DC system when the SCG is deactivated or otherwise not enabled. When a MCG link failure is detected and the SCG is deactivated, the UE may activate the SCG for the UE to use the SCG link to transmit and receive signaling messages or data as part of the MCG failure recovery procedure. When the MCG link failure is detected and the UE is configured to add the SCG upon the satisfaction of certain condition, but the condition has not occurred, the UE may check to determine whether one condition is MCG failure and whether the radio link quality of the SCG exceeds a threshold. If the radio link quality of the SCG exceeds the threshold, the UE may apply the SCG configuration to add the SCG.

Abstract: Various radio resource management techniques may be implemented to reduce in-device coexistence issues and/or interference between a Uu link established between a mobile device (first UE) and a base station (first NB), and a sidelink/PC5 link established between the first UE and another mobile device (second UE), where the second UE is served by a different base station (second NB). The first UE may receive, from the first NB, measurement configuration information that enables/configures the first UE to report to the NB any indication(s) of issues caused by communications between the first UE and the second UE over the PC5 link affecting communications between the first UE and the first NB over the Uu link, and/or communications over the Uu link affecting communications over the PC5 link. The first NB may analyze the feedback from the first UE and may implement mitigation measures to reduce/eliminate any interference and/or in-device-coexistence issues.
