Abstract: A method, an apparatus, and a computer program product for wireless communication are provided. A base station (BS) may configure a component carrier group for a user equipment (UE). The BS may provide an indication of a spatial relation for one or more sounding reference signals associated with a component carrier of the component carrier group. The UE may receive the indication and may apply the spatial relation to the one or more sounding reference signals across bandwidth parts of component carriers of the component carrier group.

Abstract: Methods (1500, 1600, 1700, 1800, 1900), systems (1000, 1400) and devices (705, 805, 1005, 1105, 1205, 1405) for wireless communications are presented. A method (1500, 1600) may include the following operations. A UE determines to perform a handover from a first source device in a first network to a first target device in the first network and from a second source device in a second network to a second target device in the second network (1505, 1605). The UE identifies a time interval for performing a first random access procedure with the first target device in the first network (1510, 1610). The UE initiates a first random access procedure with the first target device (1515, 1615). The UE performs a second random access procedure successfully with the second target device in the second network during the time interval (1520, 1620). The UE transmits or receives from the target device in the second network before the UE finishes performing the first random access procedure with the first target device in the first network (1525, 1630).

Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a user equipment (UE) may receive a response message associated with a random access message, wherein the response message includes an identifier of the UE; select a format of an uplink channel or an uplink signal for acknowledging successful decoding of the response message; determine a transmit power for hybrid automatic repeat request (HARQ) acknowledgment (ACK) information based at least in part on at least one of: a message type of the response message, a mode of random access associated with the random access message, a power control configuration used by a previous transmission of the random access message, or the format of the uplink channel or the uplink signal; and transmit the HARQ ACK information using a power control procedure based at least in part on the transmit power. Numerous other aspects are provided.

Abstract: Aspects described herein relate to configuring and selecting preamble and payload occasions for performing two-step random access procedures. Configurations on preamble occasions, payload occasions, association pattern between the occasions and synchronization signal block (SSB) beams, and the rules for selecting preamble and payload occasions for random access message transmission can be determined by the network and signaled to user equipment (UE). Based on the configurations and rules, UE can measure the link level quality and select possible preamble and payload occasions for one or more SSB beams achieving a threshold signal quality. Sets of one or more preamble occasions and one or more payload occasions can be further determined based on whether the preamble and payload occasion(s) can achieve a threshold transmission latency. The one or more preamble occasions and one or more payload occasions can be used to transmit random access messages in the two-step random access procedure.

Abstract: An apparatus, such as a base station, may determine channel conditions associated with at least two carriers on which communication with another apparatus is configured. The apparatus may encode a dataset into a set of protocol data units (PDUs) using fountain coding based on the channel conditions. The apparatus may send a first subset of the set of PDUs to the other apparatus on a first carrier of the at least two carriers. The apparatus may send a second subset of the set of PDUs to the other apparatus on a second carrier of the at least two carriers. Another apparatus, such as a user equipment (UE), may receive the set of PDUs from the apparatus over the at least two carriers, and may decode the set of PDUs to obtain a dataset using fountain coding.

Abstract: Methods, systems, and devices for wireless communications are described. A user equipment (UE) may determine a configuration of a retransmission of a first message of a random access procedure based on a set of transmission configuration options transmitted by a base station. For example, the UE may transmit the first message but may reconfigure the first message for the retransmission based on the transmission configuration options. Additionally, the UE may configure a set of transmission configuration states based on the transmission configuration options for transmitting/retransmitting the first message. In some cases, the UE may determine to switch transmission configuration states based on a trigger signaled by the base station and/or a determination by the UE. Additionally, the UE may transmit an indication of a log of state transitions performed prior to a retransmission of the first message to facilitate combining of the retransmissions at the base station.

Abstract: Methods, systems, and devices for wireless communications are described. A user equipment (UE) may communicate with a base station over a first bandwidth part (BWP) of a carrier. The UE may receive a beam failure recovery (BFR) configuration signal configuring a set of periodic channel state information reference signals (CSI-RSs) in the first BWP and a set of synchronization signals in a second BWP. The UE may measure the set of periodic CSI-RSs in the first BWP. The UE may set a beam for communicating with the base station over the first BWP based at least in part on the measuring. The UE may be a reduced bandwidth capability and support communicating with the base station using only one BWP.

Abstract: Currently, the MIMO MAC-CEs have been designed to support only one component carrier. Aspects described herein provide MAC-CEs and RRC signaling, which may facilitate efficient spatial and beam change indications for multiple component carriers. A UE may be configured to receive a configuration for each of a plurality of carriers. The UE may be configured to receive control information in a MAC-CE. The control information may comprise at least one of a TCI state, an CSI-RS resource configuration, or an SRS resource configuration. The UE may be further configured to determine whether the control information applies to multiple carriers from among the plurality of carriers. The UE may be configured to apply the control information to at least one of the plurality of carriers based on a determination of whether the control information applies to multiple carriers from among the plurality of carriers.

Abstract: This disclosure provides systems, methods and apparatuses for using a media access control (MAC) control element (CE) for dynamic RLC entities selection. In one aspect, a base station (BS) may generate and transmit the control message to a user equipment (UE) to identify active radio link control (RLC) entities, a primary RLC entity, or other parameters relating to packet data convergence protocol (PDCP) duplication-based communication. In this case, the UE may use the control message to select an RLC entity and may transmit protocol data units (PDUs) to the BS using a data radio bearer (DRB) and the selected RLC entity.
