Abstract: The present application relates to devices and components including apparatus, systems, and methods providing transmission power controls in support of expanding a network coverage. In an example, a device is configured to expand the network coverage and establishes multiple wireless links between a base station and a user equipment (UE). The device can be network-controlled, whereby such controls can include adjusting the transmission power used by the device to transmit on at least one of such wireless links.

Abstract: Apparatuses, systems, and methods for sidelink unlicensed band (SL-U) cyclic prefix extension (CPE) starting position as well as identifier (ID) restrictions for channel time occupancy (COT) sharing, including systems, methods, mechanisms for COT sharing for PSFCH multi-channel transmission, CPE starting position determination in SL-U, ID restrictions for SL-U COT sharing, and determination of when to use Type 2A, Type 2B, and/or Type 2C in SL-U COT sharing, e.g., in 5G NR systems and beyond. A UE may initiate channel access in a SL-U via an NR downlink Type A or Type B multi-channel access procedure to perform multi-channel PSFCH transmissions. The UE may secure a COT and when the COT is initiated by PSFCH type 1 channel access, the COT may not be shared with other UEs, the COT may be shared with a corresponding UE, or the COT may be shared with UEs expecting feedback during the COT.

Abstract: A user equipment (UE), a base station, a baseband processor or other network device can determine a codebook subset configuration of a plurality of multiple-input multiple-output (MIMO) layers for antenna ports of a codebook. The codebook subset configuration can include a nested structure based on a codebook configured for a fully-coherent UE, or a codebook configured for a partially-coherent UE. Fully-coherent precoders, a set of partially-coherent precoders or a set of non-coherent precoders can be configured in the codebook subset configuration to reduce a number of precoders from the partially-coherent precoders or the non-coherent precoders.

Abstract: Enhancements for a physical downlink shared channel (PDSCH) antenna ports indications for demodulation reference signal (DMRS) Type 2 with frequency domain orthogonal cover code length 4 are disclosed herein. Various embodiments herein relate the use of additional and/or replacement DMRS ports (e.g., for PDSCH) in an enhanced wireless communication system as compared to DMRS ports that may be used in legacy wireless communication systems. Various applicable scenarios are discussed. Various mechanisms for determining the additional and/or replacement DMRS ports with respect to the various discussed circumstances are also discussed.

Abstract: Described are processing time approaches to simultaneous multi-cell PUSCH/PDSCH scheduling with a single DCI (downlink control information) in a wireless communication system. In various approaches, simultaneously scheduling a plurality of physical downlink shared channels (PDSCHs) through a single DCI transmitted via a physical downlink control channel (PDCCH) occurs, wherein each of the plurality of PDSCHs is associated with a respective cell in a plurality of cells. The approaches further include transmitting data to or receiving data to a user equipment (UE) based on the scheduling information, wherein the plurality of PDSCHs occurs no earlier than a time offset following the PDCCH. In other aspects, a hybrid automatic repeat request-acknowledgement (HARQ-ACK) is received via a physical uplink control channel (PUCCH), the HARQ-ACK having been sent by a user equipment (UE) in response to one of the plurality of PDSCHs, wherein the HARQ-ACK is sent no earlier than a time offset following a reference time in one of the plurality of PDSCHs. In other aspects, transmitting data to or receiving data to a user equipment (UE) is based on the scheduling information, wherein the plurality of PDSCHs occurs no earlier than a time offset following the PDCCH, the time offset being configured to permit analog beam switching by a user equipment (UE).
