Abstract: Apparatuses, systems, and methods for SRS collision handling. A wireless device may determine whether simultaneous transmission of at least two sounding reference signals (SRSs) is allowed; if it is determined that the simultaneous transmission of the at least two SRSs is allowed, transmit the at least two SRSs simultaneously; and if it is determined that the simultaneous transmission of the at least two SRSs is not allowed, transmit one SRS of the at least two SRSs, and drop the other SRS of the at least two SRSs.

Abstract: Providing coverage enhancements for a user equipment (UE) includes decoding a random access channel (RACH) preamble received from a user equipment (UE) via a physical random access channel (PRACH). A number of repetitions associated with transmitting a random access response (RAR) over a physical downlink shared channel (PDSCH) may be determined in response to the RACH preamble. A transmission for the UE to be sent over a physical downlink control channel (PDCCH) may be encoded. The transmission may indicate the number of repetitions to the UE using one or more reserved bits of a downlink control information (DCI).

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: A WTRU may receive a slot format configuration (SFC) that indicates flexible symbols, uplink symbols, and downlink symbols. The WTRU may receive an uplink grant that is associated with the PUSCH transmission with repetitions. The received uplink grant may comprise a dedicated slot format indicator (SFI) and a resource map that indicates available resource block groups associated with the uplink symbols. The WTRU may identify an available uplink symbol based on the SFC, the SFI, and the resource map. The WTRU may identify, for the available uplink symbol, unavailable resource block groups based on the resource map. The WTRU may perform a PUSCH transmission repetition using the available uplink symbol, wherein the PUSCH transmission avoids the unavailable resource block groups.

Abstract: Beam determination refers to a set of procedures for an access node (AN) and a user equipment (UE) to select from among downlink communication beams and/or uplink communication beams for downlink and/or uplink communications, respectively. Often times, the downlink communication beams can include one or more downlink control channels, for example, a Physical Downlink Control Channel (PDCCH) and/or a Physical Downlink Shared Channel (PDSCH), to provide downlink reference signals, such as channel-state information reference signals (CSI-RSs), to the UE. The AN can execute various exemplary downlink beam scheduling procedures to control the transmission of the downlink reference signals, such as the CSI-RSs to provide an example, over the downlink communication beams. In some embodiments, the UE can utilize the CSI-RSs to perform beamforming failure detection (BFD) and beamforming failure recovery (BFR) in the wireless networks.

Abstract: A user equipment (UE) monitors for a synchronization signal block (SSB) to synchronize with a cell of a network. The UE monitors a frequency band during a discovery reference signal (DRS) window for a synchronization signal block (SSB) transmitted by a cell of the network, determines an SSB index based on information received from the cell of the network and synchronizes with the cell based on the SSB index.

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: A base station may transmit beam indication information to one or more user equipment (UE) devices. For each of a plurality of time units (e.g., symbols) in a time interval (e.g., spanning one or more slots), the beam indication information indicates a corresponding beam that the base station will use to transmit or receive. A UE device may have knowledge of the beam in which it currently resides, e.g., by performing power measurements during a beam scan procedure. Thus, the beam indication information enables the UE to perform transmissions and/or receptions (e.g., configured transmissions and/or receptions) during the appropriate time unit(s). The beam indication information may be dynamically transmitted as part of downlink control information. This transmission may omni-directional, wide beam, or narrow beam. Various schemes of encoding the beam indication information are contemplated.

Abstract: In an example method, a user equipment (UE) device determines an offset length of time associated with transmitting or receiving data over a wireless network. The UE device transmits an indication of the offset length of time to the wireless network. The UE device transmits or receives, during a first time interval, a first portion of data to or from the wireless network though a first wireless link. The UE device transmits or receives, during a second time interval, a second portion of data to or from the wireless network though a second wireless link. An end of first time interval is offset from a beginning of the second time interval by the offset length of time.

Abstract: A wireless transmit/receive unit (WTRU) may receive a PDCCH transmission comprising a CCE that is mapped to one or more REGs based on a CCE-to-REG mapping. The WTRU may receive the CCE-to-REG mapping that indicates a REG bundle corresponding to the CCE and use the CCE-to-REG mapping to identify the REGs for the WTRU. Depending on whether the CCE-to-REG mapping is interleaving or noninterleaving, the CCE-to-REG mapping may be based on different parameters. If the CCE-to-REG mapping is interleaving, the CCE-to-REG mapping may be based on an index associated with the CCE and a number of REGs in the REG bundle. If the CCE-to-REG mapping is noninterleaving, the CCE-to-REG mapping may be based on the index of the CCE.

A BSS color change announcement message may be generated having BSS color information and a color switching time. The BSS color information may indicate a BSS color for the AP and the color switching time may indicate a time until the AP switches to the BSS color.

Abstract: A user equipment (UE) may attempt to access a base station of a network.
