Abstract: Coordinated leaving for a UE having a first SIM and a second SIM may include decoding, at a baseband processor, an RRC reconfiguration message associated with the first SIM received from a first network. A communication corresponding to the second SIM received from a second network is decoded while the baseband processor is processing the received RRC reconfiguration message. The communication received from the second network is determined to comprise a higher priority than the RRC reconfiguration procedure. Based on determining, a UAI message corresponding to the first SIM is encoded by the baseband processor for transmission to the first network. The UAI message is configured to inform the first network of coordinated leaving and abortion of the RRC reconfiguration procedure. The first SIM is transitioned to an idle mode. An RRC request corresponding to the second SIM is encoded by the baseband processor for transmission to the second network.

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: A downlink control information (DCI), such as a blanking DCI (bDCI) message may be transmitted by a base station (e.g., eNB) and received by a mobile device (e.g., UE). The bDCI may indicate that the eNB will not transmit a subsequent DCI to the UE for a duration of time. The UE may be in continuous reception mode or connected discontinuous reception (C-DRX) mode. The UE may therefore determine to enter a sleep state or take other action. The bDCI may specify an explicit blanking duration, or an index indicating a blanking duration from a lookup table, and/or the blanking duration (and/or a blanking duration offset value) may be determined in advance, e.g., semi-statically. When the UE is in C-DRX mode, the UE may be configured such that either the sleep/wake period of the C-DRX mode or the blanking period of the bDCI may take precedence over the other.

Abstract: A user equipment (UE) communicates with transmission-reception points (TRPs). When the UE generates uplink control information (UCI), it determines a higher layer index (HLI) value to target the UCI to the appropriate TRP. (Possible values of the HLI are associated with the TRPs.) For UCI on Physical Uplink Control Channel (PUCCH), the HLI value may be determined: based on an HLI value configured for a control resource set (CORESET), or for particular Physical Uplink Control Channel (PUCCH) resources; based on UCI type or spatial relation data or an index related to PUCCH resources. For UCI on a configured-grant Physical Uplink Shared Channel (PUSCH), the HLI value may be based on higher layer signals or an indicator relating to channel sounding on spatial relation data. For UCI on MsgA PUSCH in a two-step random access procedure, the HLI value may be based on PUSCH resource unit or PUSCH opportunity.

Abstract: A transmitter (e.g. a packet data convergence protocol, PDCP, in the transmitter), which may be a base station for downlink communications or a user equipment device for uplink communications, may control timing of the delivery of duplicate (same) packets to multiple (e.g. two) wireless links (e.g. radio link control links) for transmission to a receiver, based at least on synchronization information received from the receiver. The duplicate packets may be transmitted over the multiple wireless links to the receiver, which may receive the duplicate packets over the multiple wireless links. The receiver may collect and/or generate synchronization information indicative of the timing or latency between the multiple wireless links, based at least on the respective receive timings of the duplicate packets over the multiple wireless links. The receiver may transmit a report containing the synchronization information to the transmitter periodically and/or in response to a trigger event.

Abstract: A wireless user equipment (UE) may employ any of various mechanisms for reporting signal quality measurements to a wireless network. The UE may impose a time delay between measurement and reporting, based on a delay parameter K. The UE may average measurements obtained at different measurement instances. The UE may employ any of various schemes for prioritizing transmission of one type of report over another, when temporal collisions occur between different types of report. The UE may employ a differential report that includes a state for indicating that a beam is not workable. The UE may employ a beam index that includes a state for indicating an invalid beam. A base station may receive a signal quality report and determine workability of a beam, e.g., by triggering a report of channel state information.

Abstract: A wireless communication device (UE) may provide information pertaining to one or more operating capabilities of the UE to LTE and 5G-NR networks. The UE may transmit information to an LTE base station directly, and to a 5G-NR base station directly, or indirectly via the LTE base station. The information may include preferred values corresponding to any number of different operating parameters associated with wireless communications or wireless communication capabilities of the UE in both LTE and 5G-NR networks, to inform and/or request the LTE and 5G-NR networks to make provisions based on the transmitted information for the wireless communications of the UE on those networks. The UE may thereby provide assistance information to LTE and 5G-NR networks in a multi-radio-access-technology dual-connectivity setting to request the respective networks to adjust certain operating capabilities of the UE in order to alleviate one or more operating issues that may be affecting the UE.

Abstract: Apparatuses, systems, and methods for performing downlink signal reception with antenna panel switching in a wireless communication system. A cellular base station may receive an indication of an antenna panel activation delay from a wireless device. The cellular base station may select a scheduling offset for a transmission to the wireless device based at least in part on the antenna panel activation delay. The scheduling offset may be selected to be at least the length of the antenna panel activation delay if it is expected that the wireless device may perform antenna panel activation to receive the transmission. The cellular base station may schedule the transmission to the wireless device using the selected scheduling offset, and may perform the transmission to the wireless device at the selected scheduling offset after scheduling the transmission to the wireless device.
