Abstract: Disclosed are methods and apparatus to enhance RACH transmission for beyond 52.6 GHz communications. A Physical Random Access Channel (PRACH) configuration information including an indication of a PRACH preamble format for a predefined subcarrier spacing (SCS) to enhance cell coverage may be received. The PRACH configuration information may include a new PRACH preamble format in a time-domain based on a short sequence PRACH preamble format. Additionally, the PRACH preamble may be transmitted using the PRACH preamble format over a PRACH to a base station (BS). The short sequence PRACH preamble format may be repeated over two consecutive time-domain RACH occasions (ROs).

Abstract: This disclosure relates to techniques for configuring listen before talk and short control signaling in unlicensed spectrum in a wireless communication system. A wireless device may establish a wireless link with a cellular base station on a cell in unlicensed spectrum. The wireless device may receive listen-before-talk configuration information, where the listen-before-talk configuration information indicates whether listen-before-talk is configured for the wireless link. The wireless device may receive short control signaling configuration information, where the short control signaling configuration information indicates whether short control signaling is enabled for one or more types of control signaling. The wireless device may perform short control signaling with the cellular base station on the wireless link when short control signaling is enabled. The short control signaling performed between the cellular base station and the wireless device may include either or both of uplink transmissions or downlink transmissions.

Abstract: Embodiments are presented herein of apparatuses, systems, and methods for a vehicle-to-everything (V2X) capable wireless device configured to perform sidelink cellular communications. The wireless device performs sidelink communications using a two-stage sidelink control information (SCI) protocol including Stage 1 SCI messaging carried on a physical sidelink control channel (PSCCH), and Stage 2 SCI messaging carried on a physical sidelink shared channel (PSSCH). The SCI messaging may be encoded using polar codes. Channel interleaving is utilized on the SCI to interleave the SCI between two or more layers of a MIMO transmission system. Scrambling for Stage 2 SCI messaging is performed based on the result of a cyclic redundancy check (CRC) performed on Stage 1 SCI messaging. Collisions between sidelink HARQ feedback to be transmitted to a base station and other transmissions are avoided based on a priority analysis of the sidelink HARQ feedback.

Abstract: Disclosed are methods, systems, and computer-readable medium to perform operations including: determining a frequency division (FD) based mapping pattern for mapping uplink (UL) demodulation reference signals (DMRS) to a single orthogonal frequency-division multiple access symbol (OFDM), where the DMRS are associated with eight antenna ports; and communicating, using the FD-based mapping pattern, a communication including a resource block that includes the UL DMRS mapped to the single OFDM symbol.

Abstract: A user equipment (UE) may receive a measurement reporting capability request from a base station and further transmit, in response to the request, an indication of the UE’s measurement reporting capability. The UE may further receive, signaling comprising a channel status information (CSI) request trigger from the base station. In response to receiving the CSI request trigger, the UE may transmit a measurement report to the base station, wherein the measurement report may comprise at least one received signal strength indicator (RSSI) measurement.

Abstract: Apparatuses, systems, and methods for providing maximum transmit power control when utilizing multiple radio access technologies. For example, a wireless communication device comprising two cellular radios may intend to transmit on the first radio, while concurrently transmitting on the second radio. To ensure compliance with a maximum transmit power limitation, the device may determine an allowed transmit power level of the first radio, representing a difference between the maximum transmit power limitation and the current transmit power level being transmitted by the second radio. The device may also determine a threshold power level for a communication by the first radio. If the allowed transmit power level meets the threshold power level, then the device may transmit the first communication having a power level between the threshold power level and the allowed transmit power level. Otherwise, the device may forego transmission of the first communication.

Abstract: Methods and devices for a UE to multiplex uplink control information (UCI). The UE establishes a connection with a base station. The UE determines whether to multiplex first UCI by first identifying whether intra-priority timing overlap exists between the timing resources of the first UCI and a PUSCH with the same priority. Subsequently, the UE identifies whether inter-priority timing overlap exists between the timing resources of the first UCI and a second PUCCH with a different priority from the first PUCCH. Finally, the UE identifies whether the timing resources of the first UCI overlap with a second PUSCH with a different priority than the first PUCCH. The UE multiplexes the first UCI based on the determination whether to multiplex the first UCI, and transmits the multiplexed first UCI to the base station.

Abstract: A device may wirelessly communicate with a number of different cells used in a carrier aggregation. The device may monitor physical downlink control channels (PDCCHs) on the different cells, dynamically switching between a dormant monitoring state (DS) and an active monitoring state (AS). In the DS, the UE may not monitor any PDCCH candidates on the active secondary SCells corresponding to the DS, or it may monitor PDCCH candidates in the search space (SS) set with the largest monitoring periodicity among the multiple SS sets on the active bandwidth part (BWP). In the AS, the UE may monitor a set of PDCCH candidates in physical resources configured by higher layers on the BWPs. Switching from one monitoring state to another may be facilitated through the use of a new downlink control information (DCI) format without data scheduling, a modified existing DCI format with data scheduling, and/or use of a DS timer.
