Abstract: Methods, systems, and devices for wireless communications are described. A non-terrestrial network (NTN) device (e.g., a satellite, base station) may transmit, to a user equipment (UE), at a first frequency a synchronization signal block (SSB) that indicates a second frequency of a control resource set (CORESET) relative to the SSB, where the second frequency is based on one or more of: a CORESET bandwidth, a combination of a first parameter associated with a first portion of the SSB and a second parameter associated with a second portion of the SSB, or both. The UE may monitor the CORESET at the indicated second frequency for a downlink control channel transmission. The NTN device may transmit, to the UE, a downlink control channel transmission over the CORESET. The NTN device may transmit, to the UE, system information based on the downlink control channel transmission.

Abstract: A base station may transmit, to a user equipment (UE), an instruction for scheduling a physical uplink shared channel (PUSCH) transmission. The PUSCH transmission may be overlapping with at least one of a slot boundary or a symbol that is configured invalid for a PUSCH by the base station, and the UE may configure a first partial PUSCH and a second partial PUSCH, the second partial PUSCH being a subset of the PUSCH transmission and including a single symbol length. The UE may schedule the second partial PUSCH based on the instruction received from the base station.

Abstract: Methods, systems, and devices for wireless communications are described A user equipment (UE) may receive, from a base station, a first control message that includes a mapping of each security key of a set of security keys to respective security key identifiers. The UE may identify that a first security key identifier is associated with one or more channels to be used for communications between the UE and the base station. In some cases, the UE may receive a control message that schedules communications via the one or more channels. The first security key identifier may be associated with a first security key of the set of security keys. The UE may communicate with the base station using the first security key. The communications with the base station may be secured using the first security key.

Abstract: A method and apparatus enable sidelink resource management using a sidelink discovery signal. The method provides for determining a resource configuration for a sidelink discovery signal. The resource configuration provides one or more parameters for transmitting the sidelink discovery signal. The method also provides for measuring link quality between the UE and at least one candidate relay UE. Based on the measured link quality one of the candidate relay UEs is selected and serves as a relay UE.

Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a user equipment (UE) may receive first information indicating a first set of parameters associated with repetition of a second random access message (RAM) associated with a random access channel (RACH) procedure. The UE may transmit, using the first set of parameters, an initial RAM in association with the RACH procedure. Numerous other aspects are described.

Abstract: Aspects of the disclosure relate to beam sweeping with controllable reflective surfaces in the presence of co-located base stations of different network operators. A first base station that is co-located at a site with a second base station may perform a first beam sweep. The first beam sweep includes transmitting a plurality of directional beams. The first base station further transmits a control signal to a controllable reflective surface to control the controllable reflective surface to reduce a likelihood of a redirection of a directional beam of a potential second beam sweep by the second base station towards a user equipment associated with the second base station. Other aspects, embodiments, and features are also claimed and described.

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: This disclosure provides systems, devices, apparatus, and methods, including computer programs encoded on storage media, for duplex switching based on network power modes. A UE may receive a first indication that a first power mode of a network entity is associated with a first duplex type for the network entity and a second power mode of the network entity is associated with a second duplex type for the network entity. The first duplex type and the second duplex type may correspond to at least one of full-duplex communication or half-duplex communication. The UE may receive a second indication of a switch from the first power mode associated with the first duplex type to the second power mode associated with the second duplex type and communicate with the network entity based on the second power mode and the second duplex type for the network entity.
