    Abstract: Method and apparatus for carrier selection for paging on a flexible cell. The apparatus receives an indication to monitor at least one carrier from a flexible cell for a paging message. The flexible cell comprising an anchor carrier and one or more non-anchor carriers. The apparatus monitors a first carrier from the flexible cell for the paging message based on the indication, the paging message associated with a PDCCH that schedules a PDSCH. The apparatus may receive, from the flexible cell, a downlink BWP configuration for the anchor carrier and the one or more non-anchor carriers.

    Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a user equipment (UE) may transmit, to a base station, a first message of a random access procedure. The UE may receive, from the base station, a second message of the random access procedure that indicates information for an uplink grant for a third message of the random access procedure, the information including a modulation and coding scheme (MCS) indication and a transmit power control (TPC) indication. The UE may transmit, to the base station, one or more repetitions of a physical uplink shared channel carrying the third message. A repetition factor for the one or more repetitions may be indicated by at least one of the MCS indication or the TPC indication. Numerous other aspects are described.

    Abstract: Certain aspects of the present disclosure provide a technique for parallel distribution matching (DM) encoding. A user equipment (UE) implements the technique to perform a first round of parallel DM encoding using k information bits as input by: 1) segmenting the k information bits into N blocks of information bits, and 2) encoding the N blocks of information bits in parallel with N DM blocks. Each of the N blocks outputs one or more encoded information bits in each of the NDM blocks, and a total number of information bits output by the N DM blocks is less than k. The UE then performs a second round of parallel DM encoding using k′ information bits that were not encoded in the first round of DM encoding. The second round of parallel DM encoding includes a same encoding process as implemented in the first round of parallel DC encoding.

    Abstract: Methods, systems, and devices for wireless communications are described. A user equipment (UE) may transmit a random access channel preamble to abase station. The UE may receive, from the base station and in response to the random access channel preamble, a grant comprising a first frequency hopping indication associated with intra-slot frequency hopping and a second frequency hopping indication associated with inter-slot frequency hopping. The UE may identify, based at least in part on the first frequency hopping indication or the second frequency hopping indication, a frequency hopping configuration for transmission of repetitions of an uplink transmission responsive to the grant. The UE may transmit the repetitions of the uplink transmission using one or more frequency Chops in accordance with the frequency hopping configuration.

    Abstract: Methods, systems, and devices for wireless communication at a user equipment (UE) are described. A UE may receive an indication of a set of random access occasions associated with a random access procedure. The UE may transmit a set of uplink random access channel messages over the set of random access occasions corresponding to the set of uplink random access channel messages. The UE may select a radio network temporary identifier for the UE based on a defined position within the set of random access occasions and receive a downlink random access channel message using the radio network temporary identifier based on the defined position within the set of random access occasions.

    Abstract: Methods, systems, and devices for wireless communications are described. A user equipment (UE) may receive, from a network entity, a downlink message associated with a first random access channel (RACH) procedure between the network entity and the UE, the downlink message including an accessibility indicator of a first cell supported by the network entity, the accessibility indicator indicating whether the first cell is inactive at a future time period. The UE may perform one of the first RACH procedure for the first cell based at least in part on the accessibility indicator indicating that the first cell supported by the network entity is active at the future time period or a second RACH procedure for a second cell based at least in part on the accessibility indicator indicating that the first cell supported by the network entity is inactive at the future time period.

    Abstract: In a probabilistic amplitude shaping (PAS) system, a distribution matching (DM) component may receive a uniform bit sequence with equal probabilities, which may be converted into symbols with a desired probability distribution (e.g., Gaussian). For example, the probability distribution may use inner constellation points associated with a lower energy and/or power more frequently and outer constellation points associated with a higher energy and/or power less frequently. In general, the DM component may map binary bits to positive amplitudes with a non-uniform distribution according to a DM rate that is based at least in part on a signal-to-noise ratio (SNR), which may vary significantly in a spatial and frequency selective wireless channel. Accordingly, some aspects described herein relate to configuring DM parameters and codeword and resource mappings in a spatial and frequency selective wireless channel.
