Abstract: Various aspects directed towards performing a random access procedure are disclosed. In one example, a parameter is identified from a plurality of parameters, and an uplink (UL) resource associated with a random access procedure is selected based on a value associated with the parameter. A random access procedure communication is then transmitted via the selected UL resource. In another example, different parameters are supported by a scheduling entity such that each of the parameters has a corresponding plurality of different potential values. Here, the scheduling entity enables a scheduled entity to select an UL resource to perform a random access procedure based on a value corresponding to a particular one of the parameters. A random access procedure communication is then received from the scheduled entity via the UL resource.

Abstract: The described techniques enable repeated physical random access channel (PRACH) preamble transmissions across multiple random access occasions (ROs) using a same spatial filter. A user equipment (UE) may transmit a PRACH preamble across multiple ROs, where each RO is associated with a same synchronization signal block (SSB) or channel state information reference signal (CSI-RS). In such cases, the PRACH repetitions may be transmitted in ROs in accordance with a mapping rule: first, in increasing order of frequency resource index; second, in increasing order of a time resource index; third, in increasing order of PRACH slot indices; and fourth, in increasing order of PRACH association period indices. Additionally, or alternatively, the PRACH repetitions may be transmitted in ROs in accordance with a mapping rule: first, in increasing order of time resource index; second, in increasing order of PRACH slot indices; and third, in increasing order of PRACH association period indices.

Abstract: Certain aspects of the present disclosure provide techniques for cyclic prefix (CP) optimization and adaptation. Certain aspects provide a method for wireless communication by a first communications device. The method generally includes determining a first CP length for communicating with a second communications device based on at least one of: an energy charging requirement of the first communications device or the second communications device or a security requirement for communications between the first communications device and the second communications device, and communicating, with the second communications device, a first signal over a first symbol, wherein the first signal comprises a first CP having the first CP length.

Abstract: A method for wireless communication at a user equipment (UE) and related apparatus are provided. In the method, the UE receives, from a network entity, a channel state information (CSI) report configuration including a set of sub-configurations. Each sub-configuration in the set of sub-configurations corresponds to a transmission setting associated with a channel state information reference signal (CSI-RS). The UE further determines one or more CSIs respectively corresponding to a subset of the set of sub-configurations, and transmits, based on the transmission setting corresponding a first sub-configuration of the subset of sub-configurations, a reduced content of a CSI report or refrains from transmitting the CSI report. The CSI report is associated with a first CSI for the first sub-configuration.

Abstract: Methods, systems, and devices for wireless communications are described. For instance, a first wireless device may receive, from a second wireless device, a first message, the first message including one or more first information blocks encoded based on a first key. The first wireless device may transmit, to the second wireless device, an indication that the one or more first information blocks have been successfully decoded. The first wireless device may communicate, with the second wireless device, a second message, where the second message includes information that is encoded based on a second key that is derived from at least a portion of the decoded one or more first information blocks.

Abstract: A base station performs joint channel estimation for a set of physical uplink control channels (PUCCHs), where one or more PUCCHs of the set of PUCCHs comprises a corresponding DMRS from a user equipment (UE). The UE receives an indication to transmit the set of PUCCHs, one or more PUCCHs of the set of PUCCHs comprising a DMRS from the base station. The base station transmits, and the UE receives, spatial filter or power control information elements for each PUCCH of the set of PUCCHs. The UE transmits the PUCCHs comprising corresponding DMRS based on a same spatial filter with a same power control parameters, spatial filter or power control information element for a first PUCCH of the set of PUCCHs indicating the same spatial filter or same power control parameter, the set of PUCCHs having phase continuity.

Abstract: Methods, systems, and devices for wireless communications are described. A example method for wireless communication at a reconfigurable reflective surface comprises receiving one or more signals from a first wireless device and determining, based at least in part on the one or more signals, measurement information pertaining to a wireless channel between the reconfigurable reflective surface and the first wireless device. The example method may further include determining, based at least in part on the measurement information, a set of weights for a plurality of reflective elements of the reconfigurable reflective surface to be used in reflecting communications between the first wireless device and a second wireless device.

Abstract: Methods, systems, and devices for wireless communications are described. For instance, a first wireless device may receive, from a controller of a reconfigurable surface, an indication of a capability of the controller of the reconfigurable surface to perform one or more operations associated with communications between the controller and the first wireless device. The first wireless device may communicate first information with the controller of the reconfigurable surface based on receiving the indication of the capability and may communicate with a second wireless device via the reconfigurable surface, where an adjustment for the reconfigurable surface for communicating with the second wireless device is based on the first information.
