Abstract: Methods, systems, and devices for wireless communications are described. A user equipment (UE) may select a beam from a set of beams and transmit an indication of the selected beam in a media access control (MAC) control element to establish a communication link with a base station. In some cases, the UE may select the beam and indicate the selection based on identifying a beam failure and/or determining to perform a random access procedure. When transmitting the indication of the selected beam, the UE may obtain an uplink resource for the transmission based on an availability of the uplink resource. For example, if the uplink resource is available, the UE may transmit the indication of the selected beam multiplexed with an uplink transmission. Alternatively, if the uplink resource is unavailable, the UE may request uplink resources for transmitting the indication of the selected beam.

Abstract: Techniques are described herein for activating and/or deactivating a semi-persistent configuration for one or more channel state information reference signal (CSI-RS) resource sets using a medium access control (MAC) control element (CE) and/or radio resource control (RRC) signaling. The MAC CE may include an indicator to indicate whether a semi-persistent configuration for a CSI resource set that includes one or more CSI resources is to be activated or deactivated. The MAC CE may also include identifiers for each of the CSI resource sets having the semi-persistent configuration activated or deactivated. In some cases, RRC messages may be used to communicate quasi-collocation (QCL) relationships associated with the CSI resources of the CSI resource sets. In some cases, the MAC CE may communicate at least some of or a portion of the information related to QCL relationships.

Abstract: Methods, systems, and devices for wireless communication are described. In some wireless communications systems, a transmitting device may identify a Radio Link Control (RLC) service data unit (SDU) to be transmitted to a receiving device. In some cases, the transmitting device may not have access to sufficient resources to transmit the entire RLC SDU. As such, the transmitting device may segment the RLC SDU into RLC SDU segments, and the transmitting device may transmit the RLC SDU segments to the receiving device. If an RLC layer at the receiving device receives one or more RLC SDU segments out of sequence, the RLC layer may initiate a reassembly (or reordering) timer. The RLC layer may reassemble the successfully received RLC SDU segments to be passed to upper layers. Once the timer expires, the RLC layer may declare that the missing RLC SDU segments are lost.

Abstract: Wireless communications systems as described herein may be configured to provide user equipment (UE) assisted information for caching data at a network node external to a core network (CN). In some cases, the UE may provide an acceleration indicator (AI) that a base station may receive and identify as caching information. The base station, upon identifying that the AI is present in an uplink packet, may transmit the packet to a gateway having a local cache. If the uplink packet does not have an AI, the base station may route the uplink packet according to an address (e.g., a uniform resource locator (URL)) contained in the packet.

Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a base station (BS) may configure a physical downlink control channel (PDCCH) component of a message B (msgB) communication to include a first portion of the signaling information for physical uplink control channel (PUCCH) for hybrid automatic repeat request (HARQ) feedback associated with the msgB communication and the signaling information for HARQ combining of msgB. The BS may configure a physical downlink shared channel (PDSCH) component of the msgB communication to include a second portion of the signaling information for PUCCH and msgB HARQ combining. The distributed mapping for the signaling information to the PDCCH and PDSCH components of msgB can be indicated by system information, RRC signaling, or hard coded in specifications. The BS may transmit the msgB communication to one or more UEs. Numerous other aspects are provided.

Abstract: Certain aspects of the present disclosure provide techniques for a hybrid automatic repeat request (HARQ) procedure for the random access channel (RACH) response message in a two-step RACH procedure. A method that may be performed by a user equipment (UE) includes sending a RACH message to a base station (BS) during a two-step RACH procedure. The RACH message includes a RACH preamble and a RACH payload. The UE monitors a RACH response message from the BS during a random access response (RAR) window. The UE transmits a retransmission of the RACH message, an acknowledgement (ACK) to the RACH response message, a negative acknowledgment (NACK) to the RACH response message, or does not transmit, to the BS based on whether a RACH response message carrying a success RAR or a fallback RAR, or no RACH response message, is received from the BS during the window.

Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a base station may transmit, and a user equipment (UE) may receive, configuration information related to a random access procedure. For example, in some aspects, the configuration information may include a physical random access channel mask configuration based at least in part on a random access occasion density in a time and frequency domain in a cell served by the base station, a random access response configuration based at least in part on an indication transmitted from the UE to the base station, and/or the like. Accordingly, the UE may perform the random access procedure based at least in part on the configuration information, which may be indicated to the UE in system information, radio resource control signaling, and/or the like. Numerous other aspects are provided.

Abstract: A MSIM UE may perform various network operations for each network subscription. However, if the MSIM UE employs subscriptions for different network operators, the UE may need to periodically tune away for an active data transmission. Such tune-away may cause the UE to miss scheduled communications from the network. Aspects of the present invention are directed to a mechanism by which a UE can notify a base station of the MSIM state, and thereby allow the network to improve scheduling for the UE to allow for periodic tune-away by the UE with minimal impact on scheduled communications. In an aspect of the disclosure, a method, a computer-readable medium, and an apparatus are provided. The apparatus may by a UE, such as MSIM UE. The apparatus may be configured to determine that the UE is associated with one or more network subscriptions, and transmit a subscription indication to a network device, wherein the subscription indication identifies a subscription state of the UE to the network.
