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: In an aspect of the disclosure, a first method, a first computer-readable medium, and a first apparatus are provided. The first apparatus may be a UE. The first apparatus may generate a payload of a first preamble message associated with a first RACH procedure, and the payload may indicate a first priority of the first RACH procedure that is relatively higher than a second priority of a second RACH procedure. The first apparatus may send the first preamble message including a RACH preamble and the payload to a base station, and the first preamble message may indicate an identifier (ID) of the first apparatus.

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.

Abstract: A configuration for multiple UEs having the same RA-RNTI to generate RA-RNTI for RACH procedures. The apparatus transmits a random access message. The apparatus receives a RAR during a RAR window in response to the random access message. The RAR window spanning at least two system frames. The apparatus determines one or more RA-RNTIs. Each RA-RNTI may be based, at least in part, on a random access channel occasion and type of random access procedure. The apparatus decodes the RAR based on the one or more RA-RNTIs.
