Abstract: Wireless communication devices are adapted to facilitate a random access procedure. According to one example, scheduled entity can transmit a first transmission that is received by a scheduling entity. The first transmission may include a physical random access channel (PRACH) preamble sequence and a first message including information for determining a device-specific network identifier for the scheduled entity. The scheduling entity may transmit a second transmission that is received by the scheduled entity. The second transmission may include information on a physical downlink control channel (PDCCH) addressed to the device-specific network identifier for the scheduled entity, and a second message on a physical downlink shared channel (PDSCH). Other aspects, embodiments, and features are also included.

Abstract: Methods, systems, and devices for wireless communication are described. A user equipment (UE) may receive, from a base station, control signaling indicating a set of connected discontinuous reception (C-DRX) configurations. The set of C-DRX configurations may include a first C-DRX configuration and a second C-DRX configuration, where at least one C-DRX configuration in the set of C-DRX configurations is a UE-group common C-DRX configuration. The set of C-DRX configurations may correspond to a discontinuous transmission (DTX) cycle of the base station. The UE may select a C-DRX configuration from the set of C-DRX configurations based on receiving the control signaling from the base station. Accordingly, the UE may use the selected C-DRX configuration to communicate with the base station. The selected C-DRX configuration may enable the base station to operate with reduced power consumption and higher DTX efficiency, among other benefits.

In some aspects, a user equipment (UE) may receive, from a base station, a dynamic indication to switch from a modulation and coding scheme (MCS) table to a new MCS table. The UE may transmit, to the base station, one or more uplink communications that use a transmit waveform type associated with the new MCS table. Numerous other aspects are provided.

Abstract: Methods, systems, and devices for wireless communications are described. In some systems, a user equipment (UE) may use a mapping to update channel state information (CSI) reporting granularity based on an antenna port configuration update. For example, the UE may store a mapping from different antenna port configurations to respective sub-band sizes for CSI reporting. In some examples, a network entity may configure the UE with the mapping. In some other examples, the UE may be pre-configured with the mapping. If the UE receives control signaling, such as downlink control information (DCI) signaling, indicating an antenna port configuration update at the network entity, the UE may use the mapping to determine a corresponding update to sub-band size granularity for CSI reporting. The UE may use the determined sub-band size for performing CSI measurements on reference signals and reporting the CSI measurements in a CSI report to the network entity.

Abstract: To more efficient sidelink communications, methods, apparatuses, and computer program products are provided. An example method of a first wireless device operating includes transmitting a sidelink discovery probing message comprising at least a first identifier of the first sidelink device. The example method further includes monitoring for a probing response from a second sidelink device. The example method further includes transmitting a sidelink discovery message if the first sidelink device receives the probing response from the second sidelink device. The example method further includes skipping transmitting the sidelink discovery message if the first sidelink device does not receive the probing response from the second sidelink device.

Abstract: Aspects of the disclosure relate to techniques for peak-to-average power ratio (PAPR) reduction based on a tone reservation (TR) algorithm. For a TR algorithm, a suitable subset of tones from among a full set of tones in a given resource allocation are reserved for use as peak reduction tones (PRT). An apparatus such as a transmission/reception point receives a set of one or more PRT sequences and stores them in memory. The transmission/reception point then determines a set of PRTs based on one or more later-received PRT sequence selection parameters. Other aspects, embodiments, and features are also claimed and described.

Abstract: Methods, systems, and devices for wireless communication are described. A user equipment (UE) may receive, from a network entity, control signaling indicating multiple network energy saving states of the network entity. The UE and the network entity may communicate one or more messages in accordance with a first energy saving state of the multiple network energy saving states. The one or more messages that are communicated may be based on a time period associated with the first network energy saving state, based on receiving a control message indicating that the first network energy saving state is active, or both.

Abstract: Methods, systems, and devices for wireless communications are described. The described techniques are directed to transmission and reception point (TRP)-specific network operation sequences. A first TRP may be configured with a first network operation sequence, and a second TRP may be configured with a second network operation sequence. The use of separate network operation sequences for different TRPs may enable some TRPs to operate in lower-power consumption modes, while simultaneously enabling a network to accommodate dynamic network traffic. Different network operation sequences may be configured with different parameters or restrictions. Different TRPs may be associated with different control resource set (CORESET) indices or different virtual component carriers. In some examples, a first TRP may indicate parameters to a UE for communicating with a second TRP in a flexible mode at the second TRP.

Abstract: Methods, systems, and devices for wireless communications are described. A user equipment (UE) may receive a configuration for a set of transmission time intervals (TTIs) including at least one TTI to be used for full-duplex communications. The UE may receive control signaling that indicates a frequency domain resource allocation (FDRA) for a physical uplink channel transmission in a first TTI. The UE may determine whether a second TTI is available for transmitting one or more repetitions of the physical uplink channel transmission based on comparing the FDRA to resources allocated to the second TTI. For example, the second TTI may be available if one or more physical resource blocks (PRBs) of the FDRA are non-overlapping in a frequency domain with downlink resources allocated to the second TTI. The UE may transmit the one or more repetitions in the second TTI based on the second TTI being available.
