Abstract: This disclosure provides systems, methods, and devices for wireless communication that support reduced bandwidth devices and particularly, allocation of control resource sets for reduced bandwidths. In a first aspect, a method of wireless communication includes receiving, from a base station at a user equipment (UE) having a first type, a master information block (MIB) within a physical broadcast channel (PBCH). The MIB includes CORESET size information and search space information for devices having a second type. The method also includes selecting a CORESET size from a plurality of preconfigured CORESET sizes based on a subcarrier spacing used to communicate with the base station. The method further includes monitoring a set of time and frequency resources to receive a message from the base station. The set of time and frequency resources has the selected CORESET size. Other aspects and features are also claimed and described.

Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a user equipment (UE) may determine to transmit a compact uplink control information (UCI) that identifies one or more parameters associated with a transmission of a physical uplink shared channel (PUSCH) communication in a PUSCH resource unit (PRU). The UE may transmit the UCI in the PRU based at least in part on a semi-static payload construction and resource mapping rule. Numerous other aspects are provided.

Abstract: A random access configuration information based on a reference SCS may allow for a unified coordinate system used by the base station and UEs that describes the time-frequency resource configuration for a two-step RACH procedure. The apparatus receives, from a base station, random access configuration information for the base station. The apparatus determines a first time duration for a preamble of a first random access message based on the random access configuration information received from the base station and a reference SCS associated with an uplink BWP configured for the first random access message. The apparatus determines a second time duration for a payload of the first random access message based on the random access configuration information received from the base station and the reference SCS. The apparatus transmits the first message to the base station to initiate a random access procedure.

Abstract: Methods, systems, and devices for wireless communications are described. A user equipment (UE) may determine a mapping between synchronization signal blocks (SSBs) and a random access message of a two-step random access procedure based on an indication in system information signaling or radio resource control (RRC) signaling. The random access message may include a random access preamble and a random access payload. The UE may determine, based on the mapping, an association between one or more beams carrying the SSBs and one or more additional beams carrying the random access preamble and the random access payload of the random access message. As a result, the UE may perform the two-step random access procedure with a base station according to the beam association, and coexist with a four-step random access procedure in a more reliable and efficient manner.

Abstract: Certain aspects of the present disclosure provide techniques for power savings for reduced capability devices. A method that may be performed by a user equipment (UE) includes receiving a shared bandwidth part (BWP) configuration and a group common BWP configuration. The group common BWP configuration indicates a group common BWP shared by a group of UEs, including the UE, having one or more common capabilities or a common UE type. The method includes communicating using the group common BWP based on the group common BWP configuration.

Abstract: This disclosure provides systems, methods, and devices for wireless communication that support inter-slot bundling and frequency hopping. In a first aspect, a method of wireless communication includes receiving a message indicating inter-slot bundling for uplink channel inter-bandwidth part (BWP) frequency hopping repetitions. The method also includes receiving bundling information and redundancy value (RV) information for an uplink channel transmission and corresponding uplink channel transmission repetitions. The method includes transmitting the uplink channel transmission with inter-slot bundling and frequency hopping and based on the bundling information and the RV information. The method further include transmitting an uplink channel transmission repetition of the uplink channel transmission with inter-slot bundling and frequency hopping and based on the bundling information and the RV information. Other aspects and features are also claimed and described.

Abstract: Methods, systems, and devices for wireless communication are described for user equipment (UE) indication of uplink scheduling information to a base station. The uplink scheduling information may provide information on a periodic traffic pattern, such as for periodic extended reality (XR) data flows. The uplink scheduling information may provide uplink assistance information (UAI) to a base station to assist the base station with providing uplink resources that efficiently serve an XR session. The UAI may indicate one or more of a periodicity of uplink traffic, an offset between uplink traffic and a packet arrival, a data size for uplink traffic for each time period associated with the XR session, a request to enable uplink transmission skipping, or any combinations thereof. A base station may provide one or more dynamic grants, configured grants, or proactive grants to a UE based on the uplink scheduling information.

Abstract: Methods, systems, and devices for wireless communications are described. A network may generate a pool of distinct base sequences for use with uplink messages from a user equipment (UE) to a base station, where each base sequence in the pool of distinct base sequences may have a peak to average power ratio below a threshold. A base station may assign the pool of distinct base sequences into groups of base sequences based on a group size and a hopping pattern reuse factor. The base station may assign the groups of base sequences to cells and signal the group size and a hopping pattern index to UEs in the cells. A UE in a cell may identify the group of base sequences assigned to the cell based on the signaled parameters and select a base sequence for use in transmitting an uplink message to the base station.
