Abstract: Methods, systems, and devices for wireless communications are described that relate to a two-step random access procedure. Generally, the described techniques allow different configurations for a first message of a random access procedure depending on a connected-state of the user equipment (UE) performing the random access procedure. A base station may transmit configuration information to the UE and the UE may use the configuration information to determine resources, coding, block size, or other factors for transmitting the first message based on the radio resource control (RRC) connected state of the UE. The UE may then monitor for a random access response from the base station based on the first message from the UE.

Abstract: Methods, systems, and devices for wireless communication are described. A first wireless device may establish a sidelink communications link with a second wireless device. The first wireless device may transmit, to the second wireless device, an indication of a capability to support a configuration for phase continuity between multiple physical channel transmissions of the sidelink communication link. The first wireless device may transmit one or more physical channel transmissions, which each may be associated with a set of one or more demodulation reference signals (DMRSs) to the second wireless device in accordance with the indicated configuration for phase continuity between the physical channel transmissions. The second wireless device may determine channel parameters associated with the one or more physical channel transmissions based on a joint channel estimation associated with the one or more sets of DMRSs.

Abstract: Methods, systems, and devices for dynamically configuring connected discontinuous reception (C-DRX) configurations supporting network power modes are described. In some examples, a user equipment (UE) may receive a first control signaling configuring the UE with multiple C-DRX configurations, each C-DRX configuration of the multiple C-DRX configurations corresponding to a respective network power mode. In some examples, the UE may receive a second control signaling including an identifier indicating a C-DRX configuration, of the multiple C-DRX configurations, corresponding to a first network power mode (e.g., an enhanced network power savings mode) at a base station, where the first network power mode may indicated a set of features active at the base station. The UE may communicate with the base station in accordance with the indicated C-DRX configuration and based on the first network power mode.

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.

Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a user equipment (UE) may identify a frequency associated with a synchronization signal block (SSB) associated with a base station. The UE may generate a security key associated with a handover of the UE based at least in part on the frequency associated with the SSB. Numerous other aspects are provided.

Abstract: Wireless positioning accuracy of a user equipment (UE) is impacted by locations of the transmit/receive points (TRPs) and UE for wireless positioning. To improve the accuracy of estimated locations, a geometric dilution of precision (GDOP) may be determined for different groups of candidate TRPs, with the GDOP indicating a potential positioning error associated with the group of candidate TRPs. A UE may determine GDOPs for different combinations of candidate TRPs. One or more devices of a wireless network (e.g., a location server and/or a UE for positioning) may select or exclude one or more candidate TRPs from being used for wireless positioning of a UE based on the determined GDOPs. Exclusion or selection of candidate TRPs for wireless positioning may also be based on quality measurements of PRSs (such as an RSRP or SNR) or a time duration associated with measuring the PRSs from the candidate TRPs to be selected.

Abstract: Methods, systems, and devices for wireless communications are described in which a user equipment (UE) may be configured with periodic uplink grants that provide a number of repetitions and a redundancy version (RV) sequence for the repetitions. Prior to the start of an uplink grant period, the UE may determine a set of slots that are available for uplink transmissions in the uplink grant period. Based on the set of slots, the UE may determine a corresponding RV for repetitions of the uplink communication associated with each slot. The slots with uplink transmissions within the uplink grant period may be non-contiguous. Repetitions of an uplink communication may be configured to be transmitted across multiple uplink grant periods, which may be triggered based on a threshold value associated with the repetitions.

Abstract: Methods, systems, and devices for wireless communications are described. A user equipment (UE) may receive, from a base station, a control message identifying a frequency hop configuration that configures the UE to use frequency hopping when transmitting repetitions of an uplink shared channel transmission. The UE, the base station, or both may determine, based on the UE being configured with the frequency hop configuration, a frequency hop for each repetition of the uplink shared channel transmission. Each frequency hop may be determined based on a corresponding uplink shared channel index for a respective repetition a frequency hop for each repetition of the uplink shared channel transmission. The uplink shared channel index may be an uplink transmission occasion index, or a repetition index. The UE may transmit the repetitions of the uplink shared channel transmission using respective frequency hops in accordance with the determination and the frequency hop configuration.

Abstract: Aspects of the present disclosure describe synchronizing frequency and/or timing in a wireless communication system. A synchronization channel frequency can be determined as one of a plurality of possible synchronization channel frequencies within a frequency band. A tone of one or more synchronization signals that corresponds to the synchronization channel frequency can be punctured, and the one or more synchronization signals can be transmitted as centered around the synchronization channel frequency.
