Abstract: Wireless communications systems may support flexible waveform configuration for autonomous uplink transmissions. A base station may transmit broadcast signaling (e g , a system information block (SIB)) indicating waveform configuration information for an autonomous uplink transmission by a user equipment (UE). In some cases, the broadcast signaling may include a waveform configuration field (WCF) that may indicate whether flexible waveforms for autonomous uplink are supported, may configure a waveform type, may indicate waveform configuration mapping rules, etc. As such, a UE may identify whether flexible waveform configuration for autonomous uplink is supported, and may determine waveform types for autonomous uplink transmissions based on waveform type configuration information from a base station (e.g., which may include an indication of whether flexible waveform configuration is supported, an indication of waveform type/scenario mapping rules, etc.), one or more LUTs, identified autonomous uplink scenarios, autonomous uplink transmission parameters, or some combination thereof.

Abstract: Aspects described herein relate to transmitting an indication of a capability to support concurrent or time division multiplexed uplink transmission of at least one of multiple uplink channels across multiple component carriers. In addition, a configuration to transmit over the at least one of the multiple uplink channels over the multiple component carriers using concurrent transmission or time division multiplexed transmission can be received based on the indication.

Abstract: A wireless device may receive a radio link control (RLC) protocol data unit (PDU) from a lower layer (e.g., from a media access control (MAC) layer) when processing communications (e.g., packets) received from another wireless device. The receiving wireless device may identify that the PDU is an RLC service data unit (SDU) segment based at least in part on an indication corresponding to a sequence number associated with the RLC SDU segment. The receiving wireless device may then determine that the RLC SDU segment is received out of order based on previously received PDUs or previously received RLC SDU segments, and initiate a reassembly timer based on the out of order determination for the RLC SDUs. If the remaining RLC SDU segments (e.g., that complete the RLC SDU) are received before reassembly timer expires, the wireless device may reassemble the RLC SDU to be passed to a higher layer.

Abstract: Increased symbol length of uplink pilot time slots (UpPTS) in special subframes is disclosed in which a configuration of a first special subframe may be independent from configuration of a second special subframe in the same frame, such that the first UpPTS of the first special subframe is longer than the second UpPTS of the second special subframe. The second UpPTS of the second special subframe may also be longer than legacy UpPTS length in select configurations. A serving base station may select the special subframe configurations in order to balance sounding reference signal (SRS) capacity for compatible user equipments (UEs) and downlink throughput for legacy UEs. The selected special subframe configurations may be transmitted by the serving base stations. In additional aspects, compatible UEs may be configured with at least two separate SRS power control parameters for use in the additional and legacy UpPTS symbols.

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: 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: 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.
