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: Aspects of this disclosure relate to resource mapping schemes. One embodiments is an apparatus including one or more processors coupled to a memory interface, and configure to encode a two part CSI that includes information bits of a first UCI type and information bits of a second UCI type. The First UCI type is a HARQ-ACK and the second the second UCI type is a SR. The encoded information bits of the first UCI type and the second UCI type are mapped onto a first physical resource. The first physical resource and a second physical resource are multiplexed in a TDM manner and the first physical resource precedes the second physical resource in a time domain. Information bits of the first and second UCI types are jointly encoded to respectively generate encoded HARQ-ACK bits and encoded SR bits. The two part CSI is output in a PUCCH.

Abstract: User equipment devices (UEs) may receive multimedia broadcast and multicast service (MBMS) transmissions over a bandwidth part (BWP) specifically allocated for MBMS point-to-multipoint (PTM) transmissions, or over MBMS-specific resources configured for PTM transmissions within a UE-dedicated BWP. The network (e.g. base station) may configure the MBMS-specific BWP for the UE for the PTM transmissions per serving cell. The MBMS-specific BWP may be used for downlink transmissions, and may be cell specific or UE specific per serving cell. The base station may provide MBMS PTM scheduling information per BWP to the UE, may indicate whether a UE-dedicated BWP may be used for PTM scheduling and transmission, and may provide the corresponding scheduling configuration when applicable. The UE may communicate its various capabilities related to MBMS reception and simultaneous reception of PTM and point-to-point (PTP) transmissions to the base station to aid the base station in scheduling communications of the UE.

Abstract: Systems and methods disclosed herein describe the use of synchronization signal/physical broadcast channel block measurement time configuration (SMTC) 2 low power (SMTC2-LP) configuration(s). For cell measurements, a UE may determine that an SMTC2-LP configuration for one or more carriers of one or more target cells is known, determine a periodicity of SMTC occasions of the carrier(s) based on data found in the SMTC2-LP configuration(s), and cancel a cell measurement of an inter-frequency cell based at least in part on the periodicity of the SMTC occasion(s). For cell re-selection, a UE may determine that an SMTC2-LP configuration for a carrier being used at a target cell is known and that a physical cell identity (PCI) of the target cell is found in data of the SMTC2-LP configuration, determine a maximum paging interruption time using this periodicity, and perform a cell reselection to the target cell within this time.

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.
