    Abstract: Systems and methods for utilizing inter -UE coordination regarding reserved resources of a sidelink (SL) resource pool are described herein. A first user equipment (UE) may identify that a first SL resource pool on a first radio access technology (RAT) overlaps with a second SL resource pool on a second RAT, sense for reservation signaling on the second SL resource pool to determine reserved resources on the second SL resource pool, and transmit resource reservation information indicating those reserved resources on SL on the first RAT. A second UE may receive the resource reservation information on the SL, identify, within the first SL resource pool, corresponding resources that overlap with the reserved resources of the second SL resource pool, select, from the first SL resource pool, transmission resources to use for a SL transmission by prioritizing resources other than the corresponding resources; and perform the SL transmission using those transmission resources.

    Abstract: Methods, systems, and apparatus, including computer programs encoded on computer storage media, for signaling cross-division duplex configurations. One of the methods includes determining, by a first device and for a symbol in a time slot of a cross-division duplex transmission link with a second device, that the first device can use a combination of multiple different symbol types across frequency to communicate with the second device at the symbol using cell-specific configuration data that indicates, for each of multiple symbols across time, various combinations of two or more symbol types from the multiple different symbol types to use to communicate across the respective symbol; and communicating, by the first device and with the second device using the cross-division duplex transmission link, across the symbol in the time slot using a first symbol type for a first bandwidth unit and a second, different symbol type for a second, different bandwidth unit.

    IPC: H04L1/18

    Abstract: A user equipment (UE), baseband processor or other network device (e.g., base station, next generation NodeB, etc. ) can operate to process or generate an acknowledgement (ACK) or a non-acknowledgement (NACK) of a beam report to indicate an autonomous transmission configuration indicator (TCI) state update, which can be a TCI update without a corresponding TCI indication /trigger. The UE can determine the ACK /NACK in response to providing the beam report in the autonomous TCI state update. The UE can then activate a TCI state of the autonomous TCI state update in response to identifying the ACK or re-transmit the beam report for autonomous TCI state update when a NACK is recognized.

    Abstract: Apparatus and methods are provided for port selection codebook configuration. A user equipment (UE) may receive, from a base station, an indication of parameter settings of a port selection codebook. The port selection codebook includes a port selection matrix W 1, a combinational coefficient matrix W 2, and a frequency basis selection matrix W f. Based at least in part on the parameter settings, the UE selects L CSI-RS ports, Mv frequency basis from a window of N consecutive frequency basis; and up to beta*L*Mv entries per layer, where beta is a percentage of the L*Mv entries per layer. The UE reports one or more of the port selection matrix W 1, the up to beta*L*Mv entries in the combinational coefficient matrix W 2 per layer, and the frequency basis selection matrix W f to the base station.

    Abstract: Configuring channel state information reference signal (CSI-RS) reporting at a network may include encoding a channel state information (CSI) reporting configuration communication for transmission to a user equipment (UE) that is in connected mode with both a first transmission and reception point (TRP) and a second TRP. The CSI reporting configuration may include a first group of CMR (Channel Measurement Resource) resources for the first TRP, and a second group of CMR resources for the second TRP. A CSI measurement communication received from the UE, may be measurements based on the CSI-RS reporting configuration communication. Based on the CSI measurement communication, one or more downlink data transmissions may be scheduled.

    Abstract: Systems and methods for beam failure recovery (BFR) are disclosed herein. A user equipment (UE) receives downlink (DL) reference signal (s) on corresponding beam (s) from a base station. The UE performs beam failure detection (BFD) on such beams used for user data to determine whether a beam failure has occurred, and candidate beam detection (CBD) on such beams not used for user data to identify candidate beams for recovering from the beam failure. The BFD and the CBD are based on both uplink (UL) channel performance considerations and DL channel performance considerations, as determined using the DL reference signal (s), such that a beam failure may be determined in the UL, the DL, or both, and a candidate beam may be identified for UL, DL, or both. The UE sends a beam failure recovery request BFRQ with this information to the base station, and the system changes beams accordingly.

    Abstract: In sidelink carrier aggregation, a first user equipment (UE) transmits data packets to a second UE using a plurality of carriers. The second UE transmits Hybrid Automatic Repeat Request (HARQ) ACK/NACK information for the data packets to the first UE via one or more Physical Sidelink Feedback Channels (PSFCHs). The aggregated carriers may be constrained to have the same PSFCH configuration, or not. Resource selection for PSSCH transmission may be performed by considering scheduled PSFCH so as to conform to transmit capability limitations and/or a half-duplex limitation of the first UE and/or the second UE. The PSFCH may be transmitted on a single carrier of said plurality, but include joint HARQ feedback for each of the carriers. Furthermore, HARQ feedback may be transmitted on a Physical Sidelink Shared Channel (PSSCHs), being signaled by the receive UE (i.e., the UE that transmits the feedback) via sidelink control information (SCI).
