Abstract: Methods, systems, and devices for wireless communications are described. To monitor a PDCCH for CA, a UE may receive PDCCH candidates in a plurality of configured component carriers (CCs). In response to a determination that a maximum number of virtual CCs that the UE is capable of monitoring for PDCCH is smaller than a number of the plurality of configured CCs, the UE groups the plurality of configured CCs into CC groups based at least in part on SCS numerologies and PDCCH monitoring configurations corresponding to span patterns within a slot of a DL subframe. The UE determines a maximum number of blind decoding operations and non-overlapped CCEs for each of the CC groups. The UE then monitors at least a first portion of the PDCCH candidates based on the maximum number of blind decoding operations and non-overlapped CCEs for each of the CC groups.

Abstract: Systems and methods provide channel state information (CSI) measurement based on measuring a demodulation reference signal (DMRS) for a physical downlink shared channel (PDSCH) transmission. A UE may determine the DMRS for the PDSCH transmission with frequency hopping, and measure the DMRS for the PDSCH transmission to determine a CSI measurement. The UE may then report the CSI measurement to a base station.

Abstract: A user equipment (UE) can operate in an unlicensed network for sidelink (SL) communications to generate SL transmission with multiple RB sets to include physical resource blocks (PRBs) in an intra-cell guard band between two adjacent RB sets that are associated with a first RB set or a second RB set. PRBs of the intra-cell guard band can belong to the first RB set with a lower frequency than the intra-cell guard band or belong to a second RB set with a higher frequency than the intra-cell guard band.

Abstract: A user equipment (UE) includes a transceiver and a processor. The processor is configured to receive, from a network and via the transceiver, a configuration for a multiple layer physical uplink shared channel (PUSCH) transmission using more than one codeword. The processor is also configured to transmit, via the transceiver and in accordance with the configuration for the multiple layer PUSCH transmission that uses more than one codeword, the multiple layer PUSCH transmission. The multiple layer PUSCH transmission is transmitted on at least a first layer of the multiple layers using a first codeword of the more than one codeword, and on at least a second layer of the multiple layers using a second codeword of the more than one codeword.

Abstract: Systems and methods for using clear channel assessment (CCA) on a channel prior to transmitting the channel are disclosed. A wireless transmission system may perform omnidirectional CCA using a CCA power threshold that is calculated based on a number of synchronization signal blocks (SSBs) transmitted by the wireless transmission system per SSB burst or per synchronization signal/physical broadcast channel (SS/PBCH) block measurement timing configuration (SMTC) window, or on a number of transmit (Tx) antennas used. A wireless transmission system may perform directional CCA on one or more Rx beams that correspond to one or more intended Tx beams using CCA power thresholds calculated based on an equivalent isotropic radiated power (EIRP) of the one or more intended Tx beams to determine directional availability of the channel. A wireless transmission system may determine a CCA power threshold based on a scaling between an actual CCA bandwidth and a nominal CCA bandwidth.

Abstract: A first cellular base station transmits a configuration message to a reporting device installed on a high-speed vehicle. The configuration message specifies one or more parameters of a Doppler measurement report. The reporting device performs one or more first Doppler measurements on the first base station and/or one or more second Doppler measurements on a second base station. The reporting device transmits the Doppler measurement report to the first and/or second base stations. The Doppler measurement report may be used by the first and/or second base stations to perform Doppler pre-compensation on transmissions to the reporting device.

Abstract: Systems and methods for sidelink (SL) power control within wireless communication systems are disclosed herein. A user equipment (UE) selects a parameter set to use to calculate a transmit power of one or more channels to be transmitted according to an SL session with a peer UE from a plurality of parameter sets each configured for use according to a distance between the UE and the peer UE. A UE determines whether an SL pathloss based calculation is to be used to calculate a transmit power of a channel according to an SL session with a peer UE, wherein that calculation is configured to be used depending on a distance between the UE and the peer UE. UE selection of a number of physical SL feedback channel (PSFCH) transmissions to match a UE capability and determinations regarding whether to perform PSFCH reception or PSFCH transmission are also discussed.
