Abstract: Methods, systems, and devices for wireless communications are described. Generally, the described techniques provide for activating antenna groups at a user equipment (UE) for communications with a base station. The UE may receive an indication of at least one active antenna group for communications with the base station, and the UE may map one or more layers of an uplink message to the at least one active antenna group. The UE may then transmit the one or more layers of the uplink message using the at least one active antenna group based on the mapping. In some cases, the UE may transmit a capability report to the base station indicating one or more antennas in each antenna group in a set of antenna groups at the UE, and the base station may activate the at least one active antenna group from the set of antenna groups.

Abstract: Methods, systems, and devices for wireless communication are described. In some systems, a base station may transmit subband uplink precoding information to a user equipment (UE). The base station may transmit a first control message to the UE to indicate a set of downlink resources for a downlink message associated with the subband uplink precoding information for the UE. The base station may transmit a second control message to the UE to indicate a set of uplink resources for an uplink message. The base station may transmit the downlink message to the UE via the set of downlink resources indicated by the first control message. The downlink message, the second control message, or both may include the subband uplink precoding information for the UE. The UE may transmit an uplink message to the base station via the set of uplink resources using the subband uplink precoding information.

Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a user equipment (UE) may receive configuration information identifying a set of sub-bands for receiving, via a set of reconfigurable intelligent surfaces (RISs), a signal. The UE may receive, via a first RIS of the set of RISs, the signal in a first sub-band of the set of sub-bands. The UE may receive, via a second RIS of the set of RISs, the signal in a second sub-band of the set of sub-bands. The UE may transmit, based at least in part on receiving the signal, RIS information indicating at least one of: first RIS information regarding the first RIS, or second RIS information regarding the second RIS. Numerous other aspects are described.

Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, an aerial user equipment (UE) may measure a first offset associated with a downlink frame based at least in part on a time when a downlink signal is received from a terrestrial base station. The aerial UE may determine a second offset corresponding to a starting time for the downlink frame at the terrestrial base station. The aerial UE may transmit an uplink message in an uplink frame using a timing advance that is based at least in part on a value of the first offset and a value of the second offset relative to a starting time associated with a global navigation satellite system frame duration. Numerous other aspects are described.

Abstract: A method for wireless communication at a user equipment (UE) and related apparatus are provided. In the method, the UE sequentially maps a first number of Sounding Reference Signal (SRS) ports to a second number of orthogonal frequency-division multiplexing (OFDM) symbols. The first number and the second number are greater than one. The UE further transmits an SRS from the first number of SRS ports over the second number of OFDM symbols based on the mapping.

Abstract: Methods, systems, and devices for determining a transmit diversity across orbital angular momentum (OAM) modes are described. In some examples, a first device may select a subset of OAM modes for a transmit diversity scheme associated with communications between the first device and a second device. The first device may transmit an indication of the transmit diversity scheme, where the transmit diversity scheme may indicate the subset of OAM modes to the second device. The first device may then transmit signaling (e.g., a data packet, one or more signals, a data stream) to the second device using a set of transmitter circles of the first device. In response, the second device may transmit a feedback message, indicating signal strength measurements associated with one or more OAM modes. The first device may determine a set of OAM modes to use for subsequent signaling based on the feedback message.

Abstract: Example implementations include a method, apparatus and computer-readable medium of wireless communication by a user equipment, comprising receiving a first configuration indicating a scheduled time at which a signal is to be communicated between the apparatus and a network entity, the scheduled time being within a time interval associated with a first network energy state of the network entity. The implementations further include receiving a second configuration mapping the signal with a second network energy state of the network entity. The implementations further include receiving or transmitting the signal at the scheduled time while the network entity is in the second network energy state based on the second configuration.

Abstract: Embodiments described herein provide for an RIS-aided determination of the location of mobile device that enables the signal reflected by the RIS to be identified through channel estimation. More specifically, an Orthogonal Cover Code (OCC)-based approach may be taken where the RIS is configured to use different weights to reflect different reference signals, enabling a receiving device to identify the reflected signal. This can be utilized on signals used for positioning of the mobile device. Additionally or alternatively, this can be used for positioning of the RIS.
