Abstract: A burden may be placed on a UE to measure CSI for combination(s) of transmission modes, and reporting may create an overhead burden. Aspects presented herein enable a UE to measure and report CSI for combinations of transmission modes in a manner that reduces such burdens. A UE receives signaling from a base station for a combination of transmission modes, e.g., comprising at least a first transmission mode and a second transmission mode. Then, the UE measures at least one reference signal for CSI feedback based on the combination of transmission modes. Various examples of measurements of CSI feedback are presented.

Abstract: A method, apparatus, and computer-readable medium are presented that enables dynamic switching of transmission modes by a UE. A UE may be configured with a transmission mode. However, the configured transmission mode might not meet the needs of changing network conditions. Aspects presented herein enable a base station to assist a UE in switching between transmission modes. The base station may signal a combination of transmission modes to the UE, e.g., including at least a first transmission mode and a second transmission mode. The UE may then monitor for one or more DCI formats in order to determine whether to switch among transmission modes from the indicated combination of transmission modes

Abstract: Various features presented herein facilitate early data transmission (EDT) in eMTC and NB-IoT. In certain aspects, a UE (e.g., an eMTC and/or NB-IoT type device), may receive an indication in a SIB from a base station that may enable EDT by the UE. The UE may transmit a random access request based on the SIB. The UE may further receive an MCS index in an RAR, and transmit a connection request (e.g., Msg3) to the base station based on the MCS index and the indication in the SIB. Some aspects described herein relate to an improved rate matching technique. In certain aspects, a UE may be configured to transmit a connection request message to a base station based on at least one of an increased number of RVs than a number of RVs for other transmissions from the UE or rate matching performed across more than one subframe.

Abstract: Methods, systems, and devices for wireless communications are described. A non-terrestrial network (NTN) cell may transmit a pre-paging message for which a user equipment (UE) may monitor based on a synchronization signal block (SSB) and a pre-paging configuration. For example, the UE may be configured with a pre-paging configuration for one or more NTN cells that may be used to identify an SS and a CORESET in which to monitor for a pre-paging message. The UE may identify the pre-paging configuration for a specific NTN cell based on a cell identifier for the NTN cell identified based on decoding an SSB from the NTN cell. The UE may identify the CORESET and the SS based on the pre-paging configuration and the resource via which the SSB was received. Thus a UE may receive a pre-paging message from an NTN based on receiving and decoding an SSB in low SINR scenarios.

Abstract: Methods, systems, and devices for wireless communication are described. A user equipment (UE), such as an unmanned aerial vehicle (UAV) (e.g., a source UAV), may initiate a unicast link establishment procedure with another UAV (e.g., a target UAV), which may enable the UAVs to communicate according to an air-to-everything (A2X) service type. The source UAV may transmit a direct communication request (DCR) message to the target UAV that includes an application-layer identifier (ID) that is unique to the target UAV. The source UAV may derive the application-layer ID for the target UAV from a UE-specific ID that is unique to the target UAV. Alternatively, the source UAV may transmit a DCR message that excludes target UAV information. Instead, the DCR message may indicate one or more proximity parameters associated with the source UAV. The UAVs may communicate unicast messages via the unicast link according to A2X configurations and communication parameters.

Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a user equipment (UE) may receive signaling identifying a control resource set (CORESET) puncturing pattern, the CORESET puncturing pattern being based, at least in part, on a number of resource blocks available before and after a CORESET puncturing process and a number of symbols of the CORESET. The UE may decode downlink control information in accordance with the CORESET puncturing pattern. Numerous other aspects are described.

Abstract: Methods, systems, and devices for wireless communications are described. A user equipment (UE) may receive control signaling from a base station that indicates a multicast or broadcast wake up signal (WUS) format. The UE may receive a multicast or broadcast WUS from the base station during a WUS monitoring occasion of a connected mode discontinuous reception (C-DRX) cycle in accordance with the control signaling. The multicast or broadcast WUS may indicate upcoming transmissions for a set of multicast or broadcast services (MBSs). If, for example, the UE is subscribed to a first MBS from the set of MBSs and the multicast or broadcast WUS indicates an upcoming transmission for the first MBS, the UE may monitor for the upcoming transmission during an active duration of the C-DRX cycle. Otherwise, the UE may enter a sleep mode to conserve power.

Abstract: A method of wireless communication at a UE is disclosed herein. The method includes receiving, from a network node, a configuration associated with a radio resource control (RRC) inactive state or an RRC idle state, wherein the configuration indicates a transmission limitation for a frequency band for aerial devices within a geographic area. The method further includes performing at least one of at least one of a cell selection or a cell reselection, based on a condition of the UE being an aerial device and based on the configuration indicating the transmission limitation.
