Abstract: Apparatuses, systems, and methods for a user equipment device (UE) to perform intra-UE co-existence between non-stand-alone (NSA) and stand-alone (SA) mode. The UE may be configured to connect to a first radio access network (RAN) operating according to a first radio access technology (RAT) via a first radio and connect to a second RAN operating according to a second RAT via a second radio. The UE may provide, to the first RAN, configuration information during a radio resource control (RRC) connection procedure. The configuration information may indicate a dual connectivity status of the UE. The dual connectivity status may include indication disabling (enabling) dual connectivity for the UE, working frequencies associated with the second RAN, and/or configurations associated with the second RAN. The UE may receive, from the first RAN, a dual connectivity configuration that may be based on the dual connectivity status of the UE and operate accordingly.

Abstract: This disclosure relates to techniques for performing radio resource control procedures for remote wireless devices in a wireless communication system. A remote wireless device may transmit a radio resource control message that includes information configured to be relayed to a cellular base station to a relay wireless device, which may relay the information to the cellular base station. The cellular base station may also transmit a radio resource control message that includes information configured to be relayed to the remote wireless device to the relay wireless device, which may relay the information to the remote wireless device.

Abstract: This disclosure relates to techniques for reducing latency in a high-propagation-delay wireless communication system. A base station (BS) may receive from a user equipment (UE) a first buffer status report (BSR) indicating an amount of uplink data buffered by the UE for transmission to the BS, and may subsequently receive a first BSR update message indicating that an additional amount of uplink data has been buffered by the UE subsequent to transmission of the first BSR. The first BSR update message may be received prior to expiration of a timer authorizing transmission of a second BSR following the first BSR. In response, the BS may allocate resources for transmission to the UE, based on the first BSR and the first BSR update message. The BS may provide an uplink grant identifying the allocated resources.

Abstract: This disclosure relates to techniques for performing conditional handovers and cell re-selections along known routes. A cellular base station may select a conditional handover set for a wireless device. The conditional handover set may include information for multiple conditional handovers. The wireless device may receive the conditional handover set. The wireless device may perform conditional handover to at least a first cell indicated in the conditional handover set based at least in part on the conditional handover set.

Abstract: Embodiments may relate to identifying, by a baseband processor, an amount of data in a data radio bearer (DRB) buffer of the baseband processor. Embodiments further relate to determining, by the baseband processor based on an indication from an application processor of the electronic device, an amount of data in at least one buffer of the application processor. Embodiments further relate to generating, by the baseband processor based at least in part on the amount of data in the DRB buffer and the amount of data in the at least one buffer of the application processor, a buffer status report (BSR). Other embodiments may be described or claimed.

Abstract: A user equipment (UE) may be configured to reattempt to establish a multiple access (MA) protocol data unit (PDU) session when the UE moves to a new registration area. The UE transmits a request for a MA PDU session to the network, receives a message from the network indicating the request has been rejected, wherein the message further includes a status indication for reattempt requests to establish the MA PDU session, determines, when the UE moves into a new registration area of a PLMN, whether reattempt requests are allowed based on, at least, the status indication and transmits, when reattempt requests are allowed, a further request to establish the MA PDU session.

Abstract: A cellular network includes a first network component configured to i) identify a first session between a first data network and a user equipment (UE), wherein the first session corresponds to a first session management function (SMF), ii) receive data network access information (DNAI) from a network function, the DNAI corresponding to a second data network and iii) select a second SMF that is to be utilized for a second session between the second data network and the UE. The cellular network also includes a second network component configured to i) store a mapping between the DNAI and the second SMF and ii) transmit an indication of the second SMF to the first network component, wherein the first network component selects the second SMF based on the indication.

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.
