Abstract: Methods, systems, and devices for wireless communications are described. A base station may transmit a set of system information to a user equipment (UE), and the UE may identify an operation mode indicating that the system information is applicable for a plurality cells. When the UE detects that it is in a new cell associated with a second base station, the UE may apply the received system information to establish a communication channel in the new cell associated with the second base station. As such, rather than receiving and decoding new system information upon detection of a new cell/base station, the UE may be able to efficiently apply the known system information to establish a connection in the new cell.

Abstract: Methods, systems, and devices for wireless communications are described. The method includes receiving a random access configuration for the UE, the random access configuration indicating a subcarrier spacing for random access preambles of a random access procedure and a periodicity of slots including random access channel occasions for transmission of the random access preambles, where the periodicity of the slots is based on the subcarrier spacing for the random access preambles, determining a random access radio network temporary identifier based on the periodicity of the slots and a slot index for a slot in which the UE is to transmit a random access preamble, and transmitting, in the slot, the random access preamble indicating the determined random access radio network temporary identifier.

Abstract: Methods, systems, and devices for wireless communications are described. The method includes a method for wireless communications at a base station. The method includes transmitting a message to a number of user equipments (UEs) over a single frequency network channel using a first beam sweep pattern. The method also includes identifying a second beam sweep pattern from a plurality of beam sweep patterns that is different from the first beam sweep pattern for retransmissions of the message. The method further includes transmitting a retransmission of the message to the plurality of UEs over the single frequency network channel using the second beam sweep pattern.

Abstract: Methods, systems, and devices for wireless communications are described. A UE may communicate with a set of transceiver nodes (e.g., transmission reception points (TRPs)) in a first transceiver node operation mode (e.g., a multi-TRP mode). A first transceiver node of the set of transceiver nodes may receive, from a second of the set of transceiver nodes, an indication to switch between rate matching states. The first transceiver node may switch from a first rate matching state to a second rate matching state and may transmit a downlink shared channel based on a resource configuration associated with the second rate matching state. The UE may receive the shared channel based on an antenna port configuration determined by the UE based on the first transceiver node operation and rate matching information. The rate matching information may be provided by the first transceiver node.

Abstract: Methods, systems, and devices for wireless communications are described. Generally, the described techniques provide for efficiently monitoring for wake-up signaling from one or more transmission and reception points (TRPs), the wake-up signaling indicating the presence of data or control information in an on-duration state of a discontinuous reception (DRX) cycle. In particular, select TRPs may be used to transmit wake-up signaling to a user equipment (UE), and the UE may be configured to monitor for wake-up signaling from the select TRPs. Once the UE receives wake-up signaling prior to an on-duration state of a DRX cycle from any of the select TRPs, the UE may then determine the TRPs scheduled to transmit data or control information in the on-duration state (e.g., based on the WUS or based on further control signaling), and the UE may receive the data or control information from the TRPs in the on-duration state.

Abstract: A method, apparatus, or computer-readable medium with instructions for beam management for radio frequency (RF) sensing at a wireless device. The wireless device performs a first beamsweep of an RF signal and measures a reflection of the RF signal based on the first beamsweep. The wireless device performs a second beamsweep of the RF signal, wherein the first beamsweep is based on a different parameter than the second beamsweep and measures the reflection of the RF signal based on the second beamsweep. The wireless device selects a beam for RF sensing based on the first beamsweep and the second beamsweep.

Abstract: Methods, systems, and devices for wireless communications are described for joint communications among a UE and multiple transmission-reception points (TRPs) in which a subset of the multiple TRPs transmit periodic tracking reference signals (TRSs) for use in measurement and beam management at the UE and the multiple TRPs. The subset of TRPs may include TRPs having a relatively large contribution to signals received at the UE, and may transmit periodic (or semi-persistent) TRSs to be measured at the UE. One of the TRPs may provide configuration information to the UE of which TRPs are included in the subset of TRPs, or the UE may determine which TRPs are included in the subset of TRPs based on a signal quality of transmissions associated with each TRP.

Abstract: Example implementations include a method, apparatus and computer-readable medium of wireless communication. A user equipment (UE) may receive a downlink control information (DCI) indicating two or more transmission configuration indication (TCI) states for a physical downlink shared channel (PDSCH). The UE may differentiate that the two or more TCI states apply to all demodulation reference signal (DMRS) ports or all transmission layers across all resource blocks and symbols for the PDSCH from TCI states that apply to different sets of DMRS ports or different sets of resource blocks or symbols. The UE may generate a composite quasi-co-location (QCL) based on the two or more TCI states in response to the differentiating. The UE may receive the PDSCH based on the composite QCL.
