Abstract: Aspects are provided to support payloads for msgA transmission in a two-step random access (RACH) procedure by providing a one-to-many mapping arrangement between preambles and physical uplink shared channel (PUSCH) resource units (PRUs). A preamble is determined by the UE which is mapped to one or more groups of PRUs to support piggybacking of uplink control information (UCI), frequency hopping on PUSCH, and multiple-slot repetition for msgA transmissions. By piggybacking UCI to a payload in msgA, flexibility may be provided in the selection of MCS and waveform as well as resource allocation for demodulation reference signals (DMRS) and PUSCH in PRUs. Moreover, by allowing a payload to hop to different frequencies on PUSCH during the transmission of msgA, a gain in frequency diversity and interference averaging may be provided, and by enabling a payload to repeat across multiple slots in msgA transmission, coverage enhancement and/or reliability may be increased.

Abstract: Methods, systems, and devices for wireless communications are described. Generally, the described techniques provide for a user equipment (UE) receiving a configuration message from a base station for supporting random access channel (RACH) type selection by the UE. The configuration message may include one or more reference signals and one or more link quality thresholds corresponding to the one or more reference signals. The UE may generate measurements of the reference signals and determine link quality for communications between the UE and the base station based on the measurements. Based on a comparison between the link quality to corresponding link quality thresholds, the UE may select a two-step random access procedure, a four-step random access procedure, or both for establishing a connection with the base station. In some cases, the UE considers system loading information, transmission parameters, or random access rules in selecting the random access procedure.

Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a user equipment may determine at least one of a downlink path loss value or an uplink path loss value associated with a base station; receive system information, a semi-persistently configured grant via RRC or a dynamic uplink grant via DCI from the base station, wherein the RRC signaling or the dynamic uplink grant identifies a power control value associated with one user or a plurality of users associated with the base station; and determine a transmit power for a data or control transmission based at least in part on at least one of the downlink path loss value or the uplink path loss value and the power control value. Numerous other aspects are provided.

Abstract: Methods, systems, and devices for wireless communications are described. A user equipment (UE) may receive an indication of a resource configuration for a random access (RA) procedure. The resource configuration may identify multiple sets of transmission resources corresponding to multiple radio resource control (RRC) states. The UE may identify an RRC state and may determine a set of transmission resources and/or a transport format based on the indication of the resource configuration, the identified RRC state, and/or a UE identifier (UE ID). The UE may transmit a first RA procedure message (e.g., a msgA) using the determined transmission resources and/or transport format. The base station may receive the message and may identify the RRC state of the UE based on the first message and transmitted indication of the resource configuration. The base station may transmit a second RA procedure message (e.g., a msgB), which the UE may receive.

Abstract: Aspects provide for wireless communication between a UE and a radio access network (RAN) node in a wireless communication network. The RAN node may generate a re-synchronization signal (RSS) for a bandwidth part (BWP) of a plurality of BWPs and transmit the RSS in the BWP of a downlink to the UE. A first bandwidth of the RSS may be based on a second bandwidth of the BWP. The UE may receive the RSS in different RRC states and perform a measurement of the RSS for synchronization, for an early detection of a paging or wake-up signal, and/or for radio resource management (RRM) measurements or radio link monitoring (RLM) measurements. The UE may utilize a communication link with the RAN node based on the measurement and the RAN node may utilize the communication link to communicate with a group of UEs sharing at least one same RSS beam.

Abstract: A user equipment (UE) may request to change its radio resource control (RRC) parameters by transmitting a UE assistance information message to a base station. However, the existing RRC parameters that a UE may request to change via a UE assistance information message may not be inadequate for some UEs and may cause a high signaling overhead. The aspects described herein include an apparatus that obtains configuration information for a UE assistance information message, the configuration information indicating a set of parameters the apparatus is allowed to indicate in the UE assistance information message, the set of parameters including at least one of an operation complexity control parameter, a network coverage control parameter, or a channel monitoring control parameter. The apparatus transmits the UE assistance information message, wherein the UE assistance information message is based on at least a portion of the set of parameters.
