Abstract: Certain aspects of the present disclosure provide techniques for identifying measurement occasions (MOs) to monitor and refrain from monitoring for a repetition of a downlink channel. An example method generally includes determining that, within a monitoring occasion (MO) duration associated with decoding a number of physical downlink control channel (PDCCH) repetitions, the UE should refrain from monitoring at least one MO associated with a first control resource set (CORESET), wherein the MO duration comprises multiple MOs in which the UE is to monitor for repeated PDCCH candidates; refraining from monitoring a first subset of MOs in the MO duration, based on the determination; and monitoring a second subset of MOs within the MO duration.

Abstract: Aspects of the present disclosure relate to wireless communications, and more particularly, to techniques for performing a random access channel (RACH) procedure. According to one aspect, a method for wireless communication by a user equipment (UE), generally includes detecting at least a first synchronization signal block (SSB) transmitted in a first bandwidth part (BWP), transmitting, in a second BWP associated with the first SSB, a number of first messages as part of a random access channel (RACH) procedure, monitoring, in the second BWP, for a second message sent in response to the number of first messages, and switching back to the first BWP to monitor for SSBs, if the second message is not received within a first timeline after transmitting the number of first messages and one or more conditions are met.

Abstract: This disclosure provides systems, methods and apparatus, including computer programs encoded on computer storage media, for configuring and signaling repetition transmissions of broadcast system information on downlink (DL) channels. In some implementations, a user equipment (UE) may receive an indication of a repetition configuration for broadcast information carried on a physical downlink shared channel (PDSCH), may identify a number of slots configured to carry the broadcast information on the PDSCH based at least in part on the repetition configuration, and may receive the broadcast information carried on the PDSCH in the number of identified slots.

Abstract: A reduced-capability user equipment (UE) uses frequency hopping to improve downlink (DL) coverage. Specifically, the UE may receive a physical downlink shared channel (PDSCH) using frequency hopping among a plurality of narrow hands in a wide bandwidth part. A bandwidth of narrow band is not larger than a maximum wireless communication bandwidth of the UE.

Abstract: Certain aspects of the present disclosure provide techniques for physical downlink control channel (PDCCH) aggregation across monitoring occasions. A method that may be performed by a user equipment (UE) includes determining a policy for monitoring one or more physical downlink control channels (PDCCHs), wherein the policy allows for mapping control channel elements (CCEs) of a single PDCCH candidate across multiple PDCCH monitoring occasions; and monitoring for signals from a network entity via the one or more PDCCHs according to the determined policy.

Abstract: Various aspects of the present disclosure generally relate to frequency hopping within a virtual BWP. In son aspects, a UE may determine a virtual bandwidth part (BWP) in which to frequency hop from a first narrow BWP to a second narrow BWP by a frequency offset. The virtual BWP may have a same subcarrier spacing as the first narrow BWP and a larger bandwidth than the first narrow BWP. The UE may perform communication based at least in part on frequency hopping within the virtual BWP. Numerous other aspects are provided.

Abstract: Methods, systems, and devices for wireless communications are described. In some systems, a user equipment (UE) may perform a random access channel (RACH) procedure with a base station. The UE may receive a message configuring a random access occasion and a PUSCH occasion. The UE may transmit a random access preamble according to the random access occasion scheduled in the message. The UE may also transmit a repetition of a physical uplink shared channel (PUSCH) data of the message corresponding to the random access occasion in each uplink transmission time interval for a defined number of uplink transmission time intervals that occur after the random access occasion.

Abstract: In an aspect, a UE and BS perform a RACH procedure whereby a preamble sequence group for a preamble is associated with a downlink receive capability of the UE. In another aspect, a UE and BS perform a RACH procedure whereby a preamble sequence group is associated with a group-specific RA-RNTI that is used to scramble an associated DCI communication. In another aspect, UEs performing a RACH procedure with a BS via different sets of ROs may monitor the same GC-DCI scrambled with a common RA-RNTI. In another aspect, a UE and BS perform a 2-Step RACH procedure whereby a Msg-A payload includes information indicative of a downlink receive capability level associated with the UE.

Abstract: Methods, systems, and devices for wireless communications are described. A group of random access channel opportunities are identified over which to transmit a preamble associated with a random access channel procedure. A preamble sequence group associated with the identified group of random access channel opportunities is determined based on a repetition level associated with the preamble sequence group. At least one downlink message associated with the random access channel procedure is received based on the repetition level.

Abstract: Aspects described herein relate to determining a failure associated with reception, by a base station, of an initial transmission of a random access message transmitted by the UE in a two-step random access procedure, and based on determining the failure situations associated with reception of the random access message, configuring the parameters of a retransmission and/or retransmitting at least a portion of the random access message.
