Abstract: Certain aspects of the present disclosure provide techniques for validation rules for message transmission occasions. In some cases, a user equipment (UE) may select a random access message transmission occasion for a preamble and a payload of a random access message, wherein the random access message transmission occasion comprises a preamble occasion and a payload occasion, select a preamble sequence for the preamble to transmit in the preamble occasion of the random access message transmission occasion of a two-step random access channel (RACH) procedure, select at least one resource unit (RU) for transmitting the payload in the payload occasion, validate the selected random access message transmission occasion based on one or more criteria, and transmit the preamble sequence and the payload in the selected message transmission occasion if the selected random access message transmission occasion is validated.

Abstract: Control channel decoding can consume a significant amount of power with respect to the device's total power battery lifetime, as well as being a factor in the complexity of device. Aspects of a method, apparatus, and computer-readable medium are presented herein that provide a solution to the problem of control channel decoding complexity and power requirements by improving the manner in which control channels are decoded. An apparatus configures an initial CORESET having a reduced bandwidth corresponding to a bandwidth capability of a first UE type. The reduced bandwidth having a narrower frequency range than a bandwidth capability of a second UE type. The apparatus may configure a first CORESET for a first UE having a first bandwidth capability and a second CORESET for a second UE having a second bandwidth capability. The apparatus transmits control channel(s) in the configured CORESET(s).

Abstract: In an aspect, a user equipment (UE) determines a resource configuration and a transmit power for a physical random access channel (PRACH) preamble sequence and/or a configuration and a transmit power for a physical uplink shared channel (PUSCH) resource unit (PRU) based on positioning information of the UE relative to the base station, the speed of the UE relative to the base station, and/or a radio resource control (RRC) state of the UE, transmits, to the base station, a message comprising the PRACH preamble sequence on a PRACH occasion and a payload on a PRU occasion based on the determined resource configuration and transmit power for the PRACH preamble sequence and/or the determined resource configuration and transmit power for the PRU, and receives, from the base station, a second message comprising information on a physical downlink control channel (PDCCH) and a payload on a physical downlink shared channel (PDSCH).

Abstract: Methods, systems, and devices for wireless communications are described. A communication device, otherwise known as a user equipment (UE) may transmit capability information including an indication of a discontinuous monitoring delay period. The UE may receive a message including an indication to adjust monitoring of a physical downlink control channel (PDCCH), and monitor for the PDCCH during the discontinuous monitoring delay period. The UE may adjust monitoring for the PDCCH following the discontinuous monitoring delay period during a temporal period based on the received indication to adjust monitoring of the PDCCH. In some examples, at least one of physical downlink shared channel (PDSCH) reception, downlink reference signal monitoring, uplink reference signal transmissions, and channel reporting is enabled during the temporal period while monitoring of the PDCCH is adjusted.

Abstract: NB wireless communication involves numerous challenges. A limited frequency dimension may need to be shared by multiple users. At times, large data transmissions, including multiple TBs of data may be transmitted using NB communication, and it may be important that each TB be successfully received by the users. The apparatus may transmit data comprising a plurality of TBs in a narrow band communications system, including repeating a transmission of the plurality of TBs, using any of a number of repetition patterns. The apparatus may use error correction encoding across multiple TBs. The transmission may be a single cell transmission or a multi-cell transmission.

Abstract: Methods, systems, and devices for wireless communications are described. A user equipment (UE) may distinguish between synchronization signal blocks (SSBs) intended for different classes of UEs. For example, a base station may transmit different SSBs in a physical broadcast channel with different configurations or parameters to indicate different UE classes, where UEs may monitor for and receive SSBs for their UE class. A UE may operate according to a UE class (e.g., New Radio (NR) Light) associated with lower bandwidths and may identify SSBs associated with this UE class to connect with a base station. The UE may identify the SSBs associated with the UE class based on a subcarrier-level offset value either implicitly or explicitly indicated to the UE. Additionally, the base station may transmit fields to indicate different parameters for subsequent communications transmitted according to the UE class.

Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a user equipment may receive a group-specific radio network temporary identifier (RNTI) associated with non-orthogonal multiple access (NOMA); receive an indication of whether the group-specific RNTI is associated with contention-based NOMA or contention-free NOMA; and selectively use a group-specific multiple access (MA) signature or a UE-specific MA signature for a NOMA transmission based at least in part on the indication. 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 RACH preamble occasion and an uplink data occasion. The message may be a radio resource control (RRC) message or a system information (SI) message. In some cases, the UE may determine if the RACH preamble occasion, the uplink data occasion, or both are restricted for cancellation based on the message. The UE may determine when to monitor a downlink control channel for dynamic scheduling based on determining which occasions are restricted for cancellation and may transmit a RACH message based on monitoring—or not monitoring—the downlink control channel for dynamic scheduling preempting a RACH occasion. In some other cases, a base station may schedule transmissions to not overlap with configured RACH occasions.
