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: A method for wireless communication by a user equipment (UE) includes receiving, from a network node, a first message indicating, for each network power mode of a group of network power modes, a group of random-access channel (RACH) process parameters. The method also includes receiving, from the network node, a second message indicating a current network power mode, of the group of network power modes, enabled at the network node. The method further includes receiving, from the network node, a third message including a physical downlink control channel (PDCCH) order that initiates a RACH process in accordance with the respective group of RACH process parameters associated with the current network power mode. The method still further includes transmitting, to the network node based on receiving the PDCCH order, a RACH preamble associated with the RACH process.

Abstract: Aspects of the present disclosure include methods and devices for energy harvesting (EH). An EH device may be configured to transmit, to an energy transfer (ET) device or a base station, an indication of an EH capability of the EH device. The ET device may be configured to transmit, to the EH device or the base station, an indication of an ET capability of the ET device. The ET device may also be configured to receive a request to transmit RF energy to the EH device. The base station may also be configured to configure transmission of RF energy from at least one ET device to the EH device based on the at least one indication of the EH capability. The EH device may also be configured to receive, and the ET device may be configured to transmit, based on the transmitted indication, RF energy.

Abstract: Certain aspects of the present disclosure provide techniques for rate-splitting multiple access (RSMA) for a user equipment (UE) group. An example method includes transmitting, to a group of receiver UEs (Rx UEs), an indication that the Tx UE will transmit to the group of Rx UEs using rate splitting multiple access (RSMA), and transmitting to the group using RSMA, wherein transmitting to the group using RSMA comprises: splitting individual messages intended for individual Rx UEs in the group into common messages and private messages, combining the common messages, transmitting the combined common messages using a first precoder, and transmitting the private messages using separate precoders.

Abstract: Some aspects of the present disclosure disclose methods and systems directed to securing downlink control information (DCI) using secret keys available to both a user equipment (UE) and a base station (BS). In some aspects, the base station may secure a DCI using one or more secret keys. The secret keys may be generated by the BS and the UE based on an estimation of a radio channel connecting the UE to the BS, and/or the secret keys may be generated at the BS using upper layer encryption techniques and shared with the UE. Upon receiving the DCI, the UE can extract the contents of the secured DCI using the secret keys.
