Abstract: Techniques and devices for signaling control and system information are provided. In one aspect, a base station determines a type of multiplexing and a periodicity for transmission of remaining minimum system information (RMSI). The type of multiplexing is for multiplexing the RMSI with a synchronization signal (SS) block. The base station generates an indicator that signals the type of multiplexing and the periodicity. In another aspect, a user equipment (UE) identifies the indicator and determines the type of multiplexing and the periodicity based on the indicator. The UE processes the transmission of RMSI based on the type of multiplexing and the periodicity. 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 may receive a multi-UE wake-up signal in a downlink control information (DCI) communication. The DCI communication may include a set of content field groups. The UE may identify a content field group of the set of content field groups that is to be read by the UE, and determine a behavior associated with performing a UE wake-up operation based at least in part on the identified content field group. Numerous other aspects are provided.

Abstract: Methods, systems, and devices for wireless communications are described. The method includes operating in narrowband communications, receiving a message in a physical broadcast channel via the narrowband communications, identifying a message type of the message in the received physical broadcast channel, decoding a master information block in the physical broadcast channel based on the identified message type, and identifying a search space for a physical downlink control channel for receiving a system information block based on the decoded master information block. In some cases, the method includes coexisting with an additional device operating in wideband communications and identifying an indication in the decoded master information block that indicates an additional master information block is to be transmitted.

Abstract: Methods, systems, and devices for wireless communications are described to enable a user equipment (UE) to bundle reference signals, such as demodulation reference signals (DMRSs), by maintaining one or more coherence properties across DMRSs. A base station may transmit an indication of a DMRS bundling configuration to the UE, and the UE may transmit a DMRS bundling capability indication to the base station. The base station may transmit DCI to the UE, and the UE may determine whether to maintain or alter DMRS bundling (for example, maintain or alter one or more coherence properties) for one or more physical shared channels based on the DCI. The UE may maintain or alter one or more coherence properties of the one or more physical shared channels based on determining whether to maintain DMRS bundling and may transmit the one or more physical shared channels and associated DMRSs to the base station.

Abstract: Methods, systems, and devices for wireless communications are described. Generally, a base station may dynamically and reliably indicate that pending transmissions are part of a full duplex operation via downlink control information (DCI) designs described herein. For example, a base station may transmit, to a user equipment (UE) a DCI including no more than one downlink grant and no more than one uplink grant for a full duplex operation. In some examples, the base station may transmit a first-stage DCI including partial information, and second-stage DCIs including full uplink and downlink grants for a full duplex operation. In some examples, the base station may configure periodic or semi-periodic uplink and downlink resources that may overlap in time, and may dynamically indicate, to the UE, whether the overlapping uplink and downlink resources are scheduled for a full duplex operation.

Abstract: Methods, systems, and devices for wireless communications are described. A user equipment (UE) may transmit uplink transmissions according to a frequency hopping pattern. The UE may identify that a first set of uplink transmissions are to be transmitted to a base station by a first set of resources (e.g., a first set of slots, a first set of frequency resources) as indicated by the frequency hopping pattern. The UE may further identify, based on the frequency hopping pattern, that a second set of uplink transmissions are to be transmitted to the base station by a second set of resources (e.g., a second set of slots, a second set of frequency resources). The first set of slots and the second set of slots may each include more than one slot. Additionally, the first and second set of resources may be within a same bandwidth part or in different bandwidth parts.

Abstract: The present disclosure describes control of user equipment (UE) transmission power level in sidelink discovery and/or communications processes. In order to reduce interference with base station and/or other UE transmissions that occur geographically proximate to a UE, sidelink power transmission levels are controlled based on one or more factors. A method in accordance with an aspect of the present disclosure includes determining at least one transmission parameter at the first UE, determining a transmit power level based on the at least one transmission parameter, and transmitting a discovery message at the determined transmit power level on a sidelink channel.

Abstract: Methods, systems, and devices for wireless communications are described. Generally, a user equipment (UE) may monitor synchronization signal resources, each synchronization signal resources associated with a beam, and may select a preferred beam based on the monitoring. The UE may transmit an uplink random access message (e.g., message 3 of a four-step random access message, message A of a two-step random access procedure, or a negative acknowledgement (NACK) message requesting retransmission of a random access message) including beam information (e.g., one or more beam indices, channel quality information, or channel state information) to a base station. In response, the base station may transmit a downlink random access message using a different beam (e.g., a new preferred beam). The UE may establish a connection with the base station based on the completed random access procedure.

Abstract: Methods, systems, and devices for wireless communications are described. Generally, a user equipment (UE) may monitor multiple synchronization signal resources, each synchronization signal resource associated with a beam of a set of beams and may determine that multiple candidate beams of the set of beams satisfy a channel quality threshold. The UE may transmit an indication that the multiple candidate beams satisfy the channel quality threshold. For example, the UE may transmit a single random access message on a physical random access channel (PRACH) resource associated with multiple candidate beams, or may transmit multiple random access messages, each one on a different PRACH resource associated with a different candidate beam. The UE may receive an indication of one of the candidate beams from the base station and may establish a connection with the base station using the indicated candidate beam.

Abstract: Certain aspects of the present disclosure provide techniques and apparats relating to designs for the remaining minimum system information (RMSI) control resource set (CORESET) and the other system information (OSI) CORESET. In certain aspects, a wireless communication device (e.g., user equipment) is enabled to determine the location of Type0-PDCCH common search space CORESET and the OSI CORESET in the frequency and time domains based on the location of the synchronization signal block (SSB) transmissions in the frequency and time domains. Determining the location of the RMSI CORESET and the OSI CORESET frequency and time resources enables the UE to receive the RMSI CORESET and the OSI CORESET, respectively.
