Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a user equipment (UE) may receive a configuration for a physical uplink control channel (PUCCH) resource for a transmission that uses multiple beams in a common time domain resource. The PUCCH resource may include multiple sets of physical resource blocks (PRBs). The UE may transmit uplink control information using the multiple beams in a respective set of PRBs of the multiple sets of PRBs of the PUCCH resource. Numerous other aspects are described.

Abstract: Methods, systems, and devices for wireless communications are described. A user equipment (UE) may receive a control message from a base station indicating a configuration of an uplink waveform for full-duplex communications at the UE. The UE may receive an additional control message scheduling a set of uplink resources and a set of downlink resources for the full-duplex communications. The set of uplink resources and the set of downlink resources may at least partially overlap in a time-domain. A frequency-domain gap between the set of uplink resources and the set of downlink resources may be based on the first uplink waveform and a first downlink waveform used by the base station. The UE may communicate with the base station on the set of uplink resources and the set of downlink resources in accordance with the frequency-domain gap.

Abstract: Disclosed are techniques for communication. In an aspect, a first node determines equiphase contour information associated with an antenna of the first node at one or more carrier frequencies, and transmits an indication of the equiphase contour information to a second node. In another aspect, a device determines equiphase contour information associated with an antenna of a first node at one or more carrier frequencies, and corrects measurement information associated with a carrier phase-based position estimation session based at least in part on the equiphase contour information.

Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, an apparatus at a network node of an internet protocol multimedia subsystem may receive a data channel resource request comprising session description protocol information corresponding to a multimedia call session between a first user equipment and a second user equipment, the data channel resource request indicating media description information associated with the multimedia call session. The apparatus may allocate, based at least in part on the session description protocol information, data channel resources corresponding to at least one data channel and associated with the first user equipment and the second user equipment. The apparatus may provide, using the at least one data channel, a first data channel application to the first user equipment and a second data channel application to the second user equipment. Numerous other aspects are described.

Abstract: An example method includes sending or receiving a session description protocol (SDP) message that includes binding information that associates a first RTP header extension and a second RTP header extension for an RTP session, wherein the binding information is indicative of a first timestamp in the first RTP header extension, and the first timestamp in the second RTP header extension, both being indicative of a time at which a first RTP packet including the first RTP header extension is transmitted. The method includes transmitting, by a first device, the first RTP packet and receiving, by the first device, a second RTP packet, the second RTP packet including the second RTP header extension including the first timestamp, a second timestamp, and a third timestamp. The method includes determining, based on at least one of the first timestamp, the second timestamp, or the third timestamp, a delay.

Abstract: Methods, systems, and devices for wireless communications are described. A reference signal distribution scheme described herein may allow for the benefits of orthogonal cover codes, and improve mechanisms to identify and address resulting carrier frequency offset. Techniques are described for distributing reference signals (e.g., demodulation reference signals) over a set of resources. The reference signals may be arranged in equi-spaced clusters, where groups of the reference signals per cluster are spaced according to a first timing offset, and where each cluster may be spaced according to a second timing offset. The network may configure the reference signal distribution scheme at various user equipments, indicating values for the timing offset. The user equipments may transmit reference signals according to the indicated scheme.

Abstract: PDCCH/PDSCH multiplexing with PDSCH data rate control is described. An apparatus is configured to receive, from a network node, DL signaling that indicates a MCS update, for a future time period, of a MCS associated with a PDSCH transmission that is multiplexed with a PDCCH transmission that includes information to schedule the PDSCH transmission. The apparatus is configured to demodulate data from the PDSCH transmission, after beginning the future time period, based on the MCS update. Another apparatus is configured to provide, for a UE, DL signaling that indicates a MCS update, for a future time period, of a MCS associated with a PDSCH transmission that is multiplexed with a PDCCH transmission that includes information to schedule the PDSCH transmission. The apparatus is configured to provide, for the UE, modulated data associated with the PDSCH transmission, after beginning the future time period, based on the MCS update.

Abstract: Systems and techniques are provided for compressing data. A process can include generating a compressed sub-packet by removing one or more sparsity bytes from a sequence of values corresponding to a sub-packet, the sequence of values including one or more sparsity bytes each equal to a configured sparsity value and one or more non-sparsity bytes each corresponding to a respective data value different from the configured sparsity value. A sub-packet header can be generated for the compressed sub-packet, and indicative of a respective location within the sequence of values of each non-sparsity byte. A packet header can be generated for a plurality of compressed sub-packets, and indicative of the configured sparsity value and respective coding information for each compressed sub-packet. A compressed data packet can be generated to include at least the packet header, the sub-packet header, and the one or more non-sparsity bytes included in the sequence of values.
