Abstract: This disclosure relates to techniques for performing consecutive conditional handovers. A cellular base station may provide conditional handover information for multiple conditional handovers to a wireless device. The conditional handover information may include information for performing a conditional handover from a cell provided by the cellular base station to at least one cell, and information for performing a conditional handover from one or more of those cells to at least one cell. The wireless device may perform multiple consecutive conditional handovers using the conditional handover information.

Abstract: User equipment (UE) operation in a single frequency network (SFN). The UE may receive one or more transmission configuration indication (TCI) states corresponding to one or more downlink resources, receive a demodulated reference signal (DMRS) wherein the DMRS is quasi co-located (QCLed) with one or more channel state information reference signal (CSI-RS) from multiple cells of a SFN and quasi co-location (QCL) information is included in the one or more TCI and determine a time and frequency offset corresponding to each of the multiple cells based on the CSI-RS.

Abstract: An approach to reduce the signaling overhead for tracking reference signal (TRS) configuration signaling to idle and inactive user equipments (UEs) operating in a wireless communication system. Conventional signaling approaches require more bits that can be conveyed in the maximum system information block (SIB) message size. One proposed approach optimizes the signaling by removing unnecessary or redundant information, using a single TRS configuration to replace multiple configurations, size reduction in some fields, and the sharing of some fields across different TRS configurations. Another proposed approach uses an SIB message to carry the TRS configurations for a particular beam or subset of beams. These two proposed approaches may be combined to provide further optimization possibilities.

Abstract: A user equipment (UE) is grouped into a paging subgroup for the purposes of receiving pages from a network. The UE receives, from the network, a paging configuration for a Radio Resource Control (RRC) idle state or an RRC inactive state paging operation, the paging configuration comprising a paging subgroup identification for the UE and monitors paging occasions based on at least the paging subgroup identification.

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 transmitting device is configured to transmit, to a second device, a medium access control (MAC) protocol data unit (PDU) comprising a plurality of MAC subPDUs, each MAC subPDU comprising at least one of a subheader, a MAC service data unit (SDU) or a MAC control element (CE), receive, from the second device, feedback indicating that the MAC PDU was received incorrectly, determine that a partial transmission scheme criteria is satisfied, transmit, to the second device, an indication that the partial transmission scheme is to be used to retransmit the MAC PDU and retransmit, to the second device, the MAC PDU using the partial transmission scheme.

Abstract: A user equipment (UE) configured to receive a first cumulative acknowledgement (ACK) from a protocol stack of the UE at a first time, store the first cumulative ACK in a queue, receive a second cumulative ACK from the protocol stack at a second time, wherein the second time occurs after the first time, store the second cumulative ACK in the queue, discard the first cumulative ACK from the queue based on the second cumulative ACK being received after the first cumulative ACK and encapsulate the second cumulative ACK to form a radio link control (RLC) packet data unit (PDU) that is to be transmitted over the air.

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: Some aspects of this disclosure relate to apparatuses and methods for implementing techniques for a user equipment (UE) having dual connectivity. The UE can communicate with a first primary base station in a first primary cell (PCell) and a second primary base station in a second PCell. The UE has dual connectivity in the second PCell using a first wireless carrier to communicate with the second primary base station and a second wireless carrier to communicate with a secondary base station in a primary secondary cell (PSCell). The UE receives a message from the first primary base station to perform a handover procedure. The UE performs the handover procedure according to the received message, and further perform an addition procedure for the secondary base station in parallel with the handover procedure. A start time of the addition procedure can be before an end time of the handover procedure.

Abstract: A user equipment (UE) reports capabilities to a network. The UE receives a request from a network for radio access capabilities of the UE, determines one or more radio access capabilities related to a supported number of component carriers (CCs) for physical downlink control channel (PDCCH) monitoring by the UE, generates the message that includes the one or more radio access capabilities of the UE and transmits the message to the network.
