Abstract: Wireless communications systems and methods related to signaling of direct current (DC) locations of user equipment devices (UEs) in a new radio (NR) network are provided. A wireless communication device receives, from a base station, at least one of a carrier aggregation (CA) configuration or a bandwidth part (BWP) configuration. The wireless communication device determines a direct current (DC) location based on at least one of the CA configuration or the BWP configuration. The wireless communication device transmits, to the base station, a report based on the determined DC location. The wireless communication device communicates, with the base station, a phase tracking reference signal (PTRS) configured based on the report.

Abstract: Methods, systems, and devices for wireless communication are described. A user equipment (UE) may autonomously initiate a handover procedure and select a target base station for the handover procedure. The UE may measure a signal from the source base station or the target base station, or both, and the UE may determine whether specific criteria at both base stations are within a pre-configured range. If the criteria at both base stations are within the pre-configured range, the UE may identify the target base station as a potential candidate for a handover. Accordingly, when the UE determines that radio conditions with the source base station are deteriorating (or fall below a threshold), the UE may initiate a handover to the target base station autonomously and without specific direction from the source base station.

Abstract: Methods, systems, and devices for wireless communications are described. A user equipment (UE) may transmit a request message to a base station while operating in an idle mode. The base station may generate, in response to the request message, a response message including a random access preamble index corresponding to the received request message. In some cases, the base station may determine a radio network temporary identifier (RNTI) based on the random access preamble index and scramble a cyclic redundancy check (CRC) of the response message with the RNTI. In some examples, the random access preamble index may be included in a payload of the response message. The UE may monitor a physical downlink control channel for the response message to the request message and receive the response message on the physical downlink control channel.

Abstract: Certain aspects of the present disclosure provide techniques for managing security keys for enciphering and deciphering packets transmitted in a wireless communications system. According to certain aspects, a method of wireless communication by a user equipment (UE) is provided. The method generally includes obtaining an indication of a key area identifier (ID) of a first cell node, wherein the key area ID identifies a set of cell nodes that are associated with a network node that uses a first key for enciphering or deciphering messages and communicating a first set of messages with the first cell node using the first key for enciphering or deciphering the first set of messages.

Abstract: Techniques are described for wireless communication. A method for wireless communication at a user equipment (UE) includes identifying, while the UE is in a connected mode with a network, a radio resource configuration of the UE, selecting a dedicated set of resources for the UE or a common set of resources for a plurality of UEs based at least in part on the identified radio resource configuration, and transmitting a pilot signal to the network using the selected set of resources. Methods for wireless communication at a network access device and a network access device controller are also described.

Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a user equipment concurrently communicates with a source base station (BS) and a target BS on a connection with the source BS and a connection with the target BS as part of a make-before-break (MBB) handover procedure; and performs a common packet data convergence protocol (PDCP) function for the connection with the source BS and the connection with the target BS before the connection with the source BS is released as part of the MBB handover procedure. Numerous other aspects are provided.

Abstract: Certain aspects of the present disclosure provide procedures for new radio (NR) cell measurement. According to certain aspects, a method of wireless communication by a user equipment (UE) is provided. The method generally includes receiving one or more downlink signals from a cell, wherein the cell is of a first cell type that supports a first set of functions or a second cell type that supports a second set of functions, wherein the second set of functions is different than the first set of functions; determining a cell type of the cell based on the one or more downlink signals; and communicating with the cell based on the determination.
