Abstract: Techniques for a high-accuracy determination the position of a light user equipment (UE) using a single base station are presented. This is accomplished by leveraging communications with a premium UE having a known location relative to the base station. Wireless reference signals measured by the light UE and premium UE, along with a reference signal from the light UE to the premium UE, can be used to determine the position of the light UE geometrically. The determination can be made by the light UE, premium UE, or a location server, depending on desired functionality.

Abstract: Aspects of the present disclosure provide techniques configuring half duplex UEs (HD-UEs) to implement supplementary downlink (SDL) in band combination that may be in same or different frequency range designations (e.g., FR1 or FR2). Particularly, in order to compensate for the loss of downlink coverage and improve load balancing, aspects of the present disclosure configure the UE to perform random-access channel (RACH), a procedure that is a shared channel used by wireless terminals to access the mobile network, on the anchor carrier in time division duplex (TDD) band and after initial access, the UE may be configured to switch to SDL to receive subsequent downlink signals.

Abstract: Methods, systems, and devices for wireless communications are described. A user equipment (UE) may receive a configuration signal configuring a set of random access opportunities over which to transmit a preamble associated with a random access procedure, each random access opportunity associated with a set of one or more uplink data opportunities. The UE may identify a repetition parameter for an uplink message. The UE may select a random access opportunity from the set of configured random access opportunities for transmitting the preamble based at least in part on the repetition parameter. The UE may transmit the preamble on the selected random access opportunity. The UE may transmit one or more repetitions of the uplink message based at least in part on the set of one or more uplink data opportunities associated with the selected random access opportunity.

Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a base station may transmit, and a user equipment (UE) may receive, configuration information related to a random access procedure. For example, in some aspects, the configuration information may include a physical random access channel mask configuration based at least in part on a random access occasion density in a time and frequency domain in a cell served by the base station, a random access response configuration based at least in part on an indication transmitted from the UE to the base station, and/or the like. Accordingly, the UE may perform the random access procedure based at least in part on the configuration information, which may be indicated to the UE in system information, radio resource control signaling, and/or the like. Numerous other aspects are provided.

Abstract: Technologies and techniques for wireless communication between a scheduled entity and a scheduling entity in a wireless communication network. A scheduled entity receives a downlink (DL) reference signal (RS) from the scheduling entity on a channel between the scheduling entity and the scheduled entity. The scheduled entity obtains channel state information (CSI) for the channel between the scheduling entity and the scheduled entity using the received DL RS, selects an uplink resource associated with a random-access procedure, and multiplexes a CSI report including the CSI with a random-access message related to the random-access procedure to produce multiplexed information.

Abstract: This disclosure provides systems, methods and apparatus, including computer programs encoded on computer storage media for a user equipment (UE), which may include a reduced capability (RedCap) UE, and a supporting cell. The UE may receive a synchronization signal block (SSB). The UE may receive a configuration of an active downlink bandwidth part (BWP) that is not configured with a SSB. The UE may tune, from the active downlink BWP to a different frequency for a layer 1 (L1) measurement gap defined by a L1 measurement gap configuration. The UE may perform a L1 measurement of the SSB on the different frequency during the L1 measurement gap. The UE may be a RedCap UE, the active BWP may be for RedCap UEs, and the SSB may define an initial BWP for the RedCap UEs and non-RedCap UEs, and the different frequency may be the initial BWP.

Abstract: Methods, systems, and devices for wireless communications are described. A base station may identify a slot format configuration, such as a time division duplex (TDD) slot format configuration, and one or more downlink repetition configurations corresponding to a number of downlink repetitions for a user equipment (UE). The base station may transmit the configurations to the UE. The UE may determine that the number of downlink repetitions and the configured slot format satisfy, or fail to satisfy, a validation rule for monitoring the number of downlink repetitions. The UE may monitor, or refrain from monitoring, the number of repetitions based on whether the validation rule is satisfied.
