Abstract: Methods, systems, and devices for wireless communications are described. A user equipment (UE) may receive downlink control information (DCI) scheduling multiple physical uplink shared channel (PUSCH) resources for a set of uplink data messages. In some examples, the scheduled PUSCH resources may overlap with reserved or preconfigured uplink resources. The UE may determine, in accordance with a multiplexing configuration, a multiplexing schedule for multiplexing the scheduled PUSCH resources with the reserved or preconfigured uplink resources. The UE may transmit the set of uplink data messages on one or more of the scheduled PUSCH resources based on the multiplexing schedule. The described techniques may enable the UE to transmit the set of uplink data messages with improved reliability based on reducing a number of collisions between the set of uplink data messages and other uplink signals transmitted on the reserved or preconfigured uplink resources.

Abstract: Methods, systems, and devices for wireless communications are described. A user equipment (UE) may transmit, to a base station, a first message of a two-step random access procedure. An attribute or content of the first message may indicate a request for a second type of control signaling that including fewer bits than a first type of control signaling. The UE may receive a second message of the two-step random access procedure including the second type of control signaling based on the first message. The UE may communicate with the base station on resources scheduled by the second message on a downlink shared channel.

Abstract: Methods, systems, and devices for wireless communications are described. A device may receive an indication of a subcarrier spacing (SCS) for communications in a plurality of transmission time intervals (TTIs), where a TTI include a set of symbols, a corresponding set of cyclic prefixes, and a padding duration. The device may receive a control signal indicating a configuration for the padding duration, at least a portion of which may be reallocated as one or more additional symbols with corresponding one or more additional cyclic prefixes. In some examples, the one or more additional cyclic prefixes and at least a first portion of the set of cyclic prefixes may be reduced in duration in comparison with a remaining portion of the set of cyclic prefixes. The device may communicate during the padding duration using the one or more additional symbols and the corresponding one or more additional cyclic prefixes.

Abstract: Methods, systems, and devices for wireless communication are described. Some user equipments (UEs) and base stations may communicate in a set of transmission time intervals (TTIs) according to a configured subcarrier spacing (SCS). Each TTI may include, in accordance with the SCS, a quantity of symbols, a corresponding quantity of cyclic prefixes, and a padding duration that may be longer than a symbol duration. The base station may transmit a control signal to the UE to indicate a configuration for the padding duration. The configuration may allocate the padding duration for reference signal repetition or one or more other operations. In some examples, the padding duration may be allocated for beam switching, and the one or more other operations may be different than beam switching. The UE and the base station may perform the reference signal repetition or the other operations during the padding duration based on the configuration.

Abstract: Methods, systems, and devices for wireless communications are described. A user equipment (UE) may receive one or more reference signals from multiple cells and may perform measurements of the reference signals. The UE may transmit, based on the measurements, a measurement report associated with a first cell and a second cell of the multiple cells, where the measurement report includes at least a first field that indicates a first identifier corresponding to the first cell and a second field that indicates a second identifier corresponding to the second cell. The measurement report may further include a resource indicator for a first reference signal of the one or more reference signals and a second resource indicator for a second reference signal of the one or more reference signals, where the first resource indicator is associated with the first identifier and the second resource indicator is associated with the second identifier.

Abstract: Methods, systems, and devices for wireless communications are described. A user equipment (UE) may receive control signaling identifying a configuration for a reference signal comprising a single carrier waveform and associated with single carrier signals for a plurality of symbol periods, the configuration indicating a plurality of channels associated with the reference signal and a set of functions associated with the reference signal. The UE may receive, according to the configuration, the reference signal in a first one or more symbol periods of the plurality of symbol periods and the single carrier signals on the plurality of channels in a second one or more symbol periods of the plurality of symbol periods. The UE may perform the set of functions on the received single carrier signals based at least in part on the received reference signal.

Abstract: Methods, systems, and devices for wireless communications are described. In some systems, a base station may configure a set of transmission parts each including different sets of time domain resources or different sets of frequency domain resources, or both, and may specify a waveform type for each of the set of transmission parts. In some examples, the base station may configure the set of transmission parts for a user equipment (UE) and, accordingly, the UE and the base station may communicate over a transmission part of the set of transmission parts via signaling that is based on a waveform type that is associated with the transmission part over which the UE and the base station communicate. The base station may control over which transmission part of the set of transmission parts the UE and the base station communicate via a configured timer or via explicit activation and deactivation signaling.

Abstract: Methods, systems, and devices for wireless communication are described. Generally, the described techniques provide for a base station to determine whether to perform coverage enhancement for a random access procedure and to transmit an indication to a user equipment (UE) accordingly. For example, a base station may transmit an indication of whether coverage enhancement is associated with a second random access message (e.g., a random access Message 4 (Msg4)) using a first random access message (e.g., a random access Message 2 (Msg2)). The base station may transmit, and the UE receive, the second random access message accordingly. Implementing aspects of the present disclosure may enable coverage enhancement for random access procedures in wireless communications systems.
