Abstract: Inter-cell beam management and inter-cell multiple transmission and reception point (multi-TRP) operation may include decoding a cell-specific reference signal (CRS) pattern list configuration received from a base station. The CRS pattern list configuration may include one or more CRS pattern lists. Each of the one or more CRS pattern lists correspond to one or more cells of a plurality of cells configured by the base station. Beam management associated with the plurality of cells may be performed based on the CRS pattern list configuration.

Abstract: Disclosed are techniques for reducing likelihood of Random Access Channel (RACH) transmission blockages and thereby facilitate an initial access procedure for new radio (NR) unlicensed spectrum (NR-U) operation in a fifth generation (5G) wireless communication system including an NR node. In some embodiments, a parameter generated by a gNB and received by a UE indicates that, from among a set of consecutive RACH Occasions (ROs), a gap is available for performing a listen-before-talk (LBT) procedure before commencing a RACH transmission.

Abstract: A user equipment (UE) performs uplink (UL) transmissions to a network. The UE receives a frequency domain resource allocation (FDRA) configuration from a network, the FDRA configuration comprising at least one of a first FDRA mode or a second FDRA mode, wherein the first FDRA mode utilizes an FDRA unit comprising a set of consecutive resource blocks (RBs) and the second FDRA mode utilizes an FDRA unit comprising a set of interlaced RBs, when both of the first and second FDRA modes are configured, the UE receives a signal indicating which one of the two FDRA modes are to be used for an uplink (UL) transmission and performs the UL transmission in accordance with the indicated FDRA mode.

Abstract: A computer readable storage medium, a user equipment, a method and an integrated circuit that are used to perform operations. Operations include receiving, from a network, a plurality of Physical Downlink Shared Channel (PDSCH) transmissions in slots of a hybrid automatic repeating request acknowledgement (HARQ-ACK) window, decoding each of the PDSCH transmissions in the slots of the HARQ window, determining a HARQ-ACK feedback for each PDSCH transmission in the HARQ-ACK window, bundling the HARQ-ACK feedback for at least two of the PDSCH transmissions and reporting the bundled HARQ-ACK feedback for the HARQ window to the network.

Abstract: Apparatus and methods are provided for port selection codebook configuration. A user equipment (UE) may decode a channel state information (CSI) report configuration (CSI-ReportConfig) from a base station. The CSI-ReportConfig configuring a port selection codebook comprising a port selection matrix W1, a combinational coefficient matrix W2, and a frequency basis selection matrix Wf. Based on the CSI-ReportConfig, the determines, for the port selection matrix W1, up to L CSI reference signal (CSI-RS) ports out of P CSI-RS ports configured for measuring and reporting CSI. For the frequency basis selection matrix Wf, the UE determines up to Mv frequency basis out of N frequency basis. For the combinational coefficient matrix W2, the UE determines up to L*Mv entries per layer. The UE reports one or more of the port selection matrix W1, the combinational coefficient matrix W2, and the frequency basis selection matrix Wf to the base station.

Abstract: A user equipment (UE), or other network component can operate to configure channel state information (CSI) feedback in response to receiving a CSI-reference signal (CSI-RS) according to a hierarchical precoding scheme that selectively reduces a feedback overhead associated with the CSI feedback. The UE can operate to divide and further sub-divide a frequency band (e.g., a wideband, or particular frequency part) into a precoding hierarchy to generate precoders for conveyance to a base station, eNodeB (eNB), or next generation NodeB (gNB) via the CSI feedback.

Abstract: Systems and methods for the use of measurement object having multiple synchronization signal block (SSB)-based measurement timing configurations (SMTCs) indicating a same periodicity and different offsets are disclosed herein. In some of these cases, a wireless communications network can provide a user equipment (UE) with a measurement object (MO) having up to a total number of total SMTCs. or having SMTC sets each of up to a predetermined number of SMTCs. UE determinations regarding a number of the SMTCs to use to perform one or more corresponding SSB measurements during a period of a periodicity indicated by one or more SMTCs of an MO are also discussed. The use of scheduling restrictions by the UE based on non-terrestrial network (NTN) characteristics of one or more of a serving cell and a neighbor cell to be measured are also discussed.
