Abstract: RACH occasion repetition and PRACH format selection in an NTN are disclosed. The base station may determine, based on at least one beam, a first PRACH configuration for at least one first UE and a second PRACH configuration for at least one second UE. The base station may transmit, to at least one of the at least one first UE or the at least one second UE, an indication of the first PRACH configuration and the second PRACH configuration. The UE, based on whether it is a first UE or a second UE, may select, based on the received indication, the first PRACH configuration or the second PRACH configuration for at least one beam. The UE may initiate, via the at least one beam, a RACH procedure for the selected first PRACH configuration or the selected second PRACH configuration.

Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a user equipment (UE) may receive, from a network node, information that indicates a periodic sequence of network energy saving (NES) states that are each associated with an antenna configuration of the network node. The UE may receive, from the network node during a current time period, one or more downlink transmissions using a maximum quantity of multiple input multiple output (MIMO) layers associated with an active NES state that is identified for a current time period based at least in part on the periodic sequence of NES states. Additionally or alternatively, the UE may transmit, to the network node during the current time period, one or more sounding reference signal (SRS) transmissions using an SRS antenna sounding configuration associated with the active NES state for the current time period. Numerous other aspects are provided.

Abstract: Methods, systems, and devices for wireless communications are described. The described techniques support decoupled uplink and downlink communications via reconfigurable intelligent surfaces. Generally, the described techniques provide for using different passive network nodes for uplink and downlink communications. A user equipment (UE) may receive, from a base station, an indication of a first transmission configuration indicator state for downlink communications with the base station and a second transmission configuration indicator state for uplink communications with the base station. The UE may receive, from the base station via a first passive device (e.g., a first reconfigurable intelligent surface (RIS)) associated with the first transmission configuration indicator state, a downlink message in a radio frame. The UE may transmit, to the base station via a second passive device (e.g., a second RIS) associated with the second transmission configuration indicator state, an uplink message in the radio frame.

Abstract: Methods, systems, and devices for wireless communications are described. A UE may receive, from a base station, an indication of a degree of UE loading for at least one of a set of reconfigurable reflective surfaces that are configured to assist in communications between the UE and the base station. The UE may select a reconfigurable reflective surface for use in the communications between the UE and the base station based on the degree of UE loading of the selected reconfigurable reflective surface, and transmit a signal to the base station via the selected reconfigurable reflective surface. In some cases, the UE may receive, from the base station, an indication for the UE to use a different reconfigurable reflective surface than the selected reconfigurable reflective surface, and may transmit a second signal to the base station via a second reconfigurable reflective surface based on the indication.

Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a user equipment (UE) may identify a maximum number of multiple-input multiple-output (MIMO) layers for a communication based at least in part on at least one of a number of channel state information reference signal (CSI-RS) ports associated with a network node, or a transition of a transmission reception point (TRP) associated with the network node to or from a dormancy state. The UE may perform the communication in accordance with the maximum number of MIMO layers. Numerous other aspects are described.

Abstract: A method of wireless communication by a base station includes configuring a tracking reference signal (TRS) with respect to a physical downlink shared channel (PDSCH) for an idle/inactive mode user equipment (UE). The method also transmits the tracking reference signal and the PDSCH during a paging cycle, in accordance with the configuration. A method of wireless communication by a UE includes expecting a TRS to be received when a PDSCH is received.

Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a user equipment (UE) may receive a first indication that a network node is in a sleep mode. The UE may receive a second indication of periodic wake-up signal (WUS) occasions associated with the sleep mode. The UE may receive a third indication to defer, for one or more WUS occasions, a transmission of a WUS associated with data, deferral of the transmission being based at least in part on a latency parameter associated with the data. Numerous other aspects are described.

Abstract: Apparatus, methods, and computer-readable media for improving uplink data channel repetitions using multiple slot transmit time intervals are disclosed herein. An example method for wireless communication at a user equipment (UE) includes receiving scheduling downlink control information (DCI) indicating, in a time domain resource allocation (TDRA) field, a scaling parameter for a transport block size (TBS) of a physical uplink shared channel (PUSCH) transmission for transmission as PUSCH repetitions over a repetition unit comprising a plurality of single repetitions. The example method also includes transmitting the PUSCH repetitions with scaling based on the scaling parameter indicated in the scheduling DCI.

Abstract: Methods, systems, and devices for wireless communications are described. A user equipment (UE) may transmit a random access channel preamble to abase station. The UE may receive, from the base station and in response to the random access channel preamble, a grant comprising a first frequency hopping indication associated with intra-slot frequency hopping and a second frequency hopping indication associated with inter-slot frequency hopping. The UE may identify, based at least in part on the first frequency hopping indication or the second frequency hopping indication, a frequency hopping configuration for transmission of repetitions of an uplink transmission responsive to the grant. The UE may transmit the repetitions of the uplink transmission using one or more frequency Chops in accordance with the frequency hopping configuration.
