Abstract: Methods, systems, and devices for wireless communications are described. A user equipment (UE) may receive, from a base station, control signaling indicating a set of sub-bandwidth part (BWP) channel configurations for wireless communications at the UE, where each sub-BWP channel configuration of the set of sub-BWP channel configurations may include one or more sets of resources spanning at least a portion of a respective BWP in the frequency domain. The UE may receive, from the base station, a control message indicating a first sub-BWP channel configuration of the set of sub-BWP channel configurations, the first sub-BWP channel configuration supporting wireless communication for a full-duplex communication mode and a half-duplex communication mode.

Abstract: Apparatus, methods, and computer-readable media for network coding for dual connectivity are disclosed herein. A base station (BS) sends encoded symbols from a first network coding layer to a first radio link control (RLC) layer and transmits, to a user equipment (UE), encoded data comprising the encoded symbols. The BS also transmits encoded data to a road side unit (RSU) for passing to the UE as a split transmission. The UE can receive encoded packets from the BS and RSU at a network coding layer via a second RLC layer. The UE recovers source packets from the encoded packets with a rateless network code at the network coding layer. The UE sequences the source packets into an ordered set of source packets at the network coding layer and sends the ordered set of source packets from the network coding layer to a packet data convergence protocol layer for processing.

In some aspects, a user equipment (UE) may receive a configuration message indicating a scheduling request configuration that includes at least one resource associated with a half-duplex mode of the UE and at least one resource associated with a full-duplex mode of the UE. The UE may transmit a scheduling request using the at least one resource associated with the half-duplex mode or the at least one resource associated with the full-duplex mode. Additionally, or alternatively, the configuration message may indicate a logical channel that maps to a corresponding scheduling request configuration associated with a half-duplex mode of the UE, to a corresponding scheduling request configuration associated with a full-duplex mode of the UE, or to a combination thereof. Accordingly, the UE may transmit the scheduling request using the logical channel. Numerous other aspects are described.

Upon failing to recover the source packets, the UE may transmit, over a sidelink channel, a message requesting sidelink assistance in recovering the source packets.

Abstract: Methods, systems, and devices for wireless communications are described. Generally, a user equipment (UE) implement a timer (e.g., a round-trip time (RTT) timer) during which it does not monitor a physical downlink control channel (PDCCH). The UE may initiate the timer after transmitting a first random access message or a four-step random access message, or transmitting or retransmitting a third random access message of a four-step random access procedure, or after a physical uplink control channel (PUCCH) resource for hybrid automatic repeat request (HARQ) feedback for a fourth message of a four-step random access procedure. The UE may initiate the timer after transmitting a first message of a two-step random access procedure, or after a PUCCH resource for HARQ feedback for a second message of a two-step random access procedure, or after a fixed offset from the end of a PDSCH of a two-step random access procedure.

Abstract: Methods, systems, and devices for wireless communications are described that support signaling of compressed gradient vectors in a machine learning system that utilizes federated learning. The compressed gradient vectors may be used to report stochastic gradients from multiple edge devices (e.g., multiple user equipment (UE) devices) that are combined into a global model at an edge server (e.g., a base station). A base station may configure a UE with one or more parameters for quantizing a local stochastic gradient, and for reporting the quantized local stochastic gradient in a set of compressed gradient vectors. Each vector of the compressed gradient vectors may be associated with a different stage of a multi-stage compression procedure for reporting the local stochastic gradient, and multiple reports from multiple UEs may be aggregated in a federated learning procedure associated with a machine learning algorithm.

Abstract: Methods, systems, and devices for wireless communications are described. A rateless code may be used to generate n encoded packets based on a set of source packets. A modulation technique may be used to generate first symbol packets from the encoded packets. And a layered modulation technique may be used to generate coded symbol packets from the first symbol packets. The layered modulation technique may include generating a coded symbol packet from a group of first symbol packets. Different weights may be applied to the different first symbol packets included in the group of first symbol packets before the first symbol packets in the group are combined together. A receiving device may demodulate the transmitted coded symbol packets to reconstruct the group of first symbol packets, use the reconstructed group of first symbol packets to recover the encoded packets, and use the encoded packets to reconstruct the source packets.
