Abstract: Uplink transmissions of a mobile device (UE) may be improved in a number of ways. Uplink Transmission Time Interval (TTI) bundling, including both Type-A and Type B PUSCH repetitions, may be implemented with variable TTI bundle sizing. The TTI bundle size may be determined by a base station and communicated to the UE explicitly, or may be determined by the UE implicitly, based on an indicated repetition number and frequency hopping number. The UE may also report frequency hopping (FH) assist information to the base station for use by the base station to more efficiently configure FH for the uplink transmissions. Finally, the UE may use (or maintain) the same transmission power, for each TTI transmit occasion of the same TTI bundle in order to improve (cross-slot) channel estimation accuracy. Power allocation may be prioritized to ensure that at the same time a total power for the uplink transmissions of the UE does not exceed a specified threshold.

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 user equipment (UE) may attempt to access a base station of a network. The UE receives, from the base station of a wireless network, a broadcast including a system information block (SIB) identifying a plurality of random access channel (RACH) sub-bands of an uplink (UL) bandwidth and which of the plurality of RACH sub-bands includes physical random access channel (PRACH) resources. The base station selects one of the plurality of RACH sub-bands for a PRACH transmission and selects a preamble from the selected RACH sub-band and transmit the preamble to the base station to initiate a RACH procedure.

Abstract: A sidelink transmission and an uplink transmission that is carrying a sidelink hybrid automatic repeat request (HARQ) are both scheduled for transmission in a shared time window. If a priority associated with the sidelink HARQ is considered to be higher than a priority associated with the sidelink transmission, then a higher priority is assigned to the uplink transmission, regardless of whether the uplink transmission contains other uplink data. Otherwise, if the uplink transmission does not carry other uplink data, then the higher priority is assigned to the sidelink transmission. Greater transmission resources are given to the transmission with the higher priority.

Abstract: A base station configures a user equipment (UE) to monitor a Physical Downlink Control Channel (PDCCH). The base station receives, from the UE, a reduced PDCCH monitoring capability for at least one group of search space sets (SSS) of a PDCCH, determines a reduced monitoring capability (MO) configuration for the UE based on the reported reduced PDCCH monitoring capability and transmits the reduced MO configuration to the UE.

Abstract: Embodiments include a computer readable storage medium, a user equipment, a method and an integrated circuit that perform operations. The operations include receiving a downlink channel information (DCI) format 2_0 from a g-NodeB (gNB) connected to the 5G NR network, wherein the DCI format 2_0 includes channel occupancy time (COT) duration and a gap threshold value, determining if a nonzero power channel state information reference signal (NZP-CSI-RS) resource is valid, wherein the NZP-CSI-RS resource is valid if the NZP-CSI-RS resource is within the COT duration and if a gap between a last symbol of the DCI format 2_0 and a first symbol of the NZP-CSI-RS resource is greater than the gap threshold value.
