Abstract: Aspects relate to configuration of a single sounding reference signal (SRS) resource set for a UE that includes SRS resources associated with multiple, different transmission and reception points (TRPs). A radio access network (RAN) entity, which may be associated with one or more of the TRPs, may configure an SRS configuration for the SRS resource set and transmit the SRS configuration to the UE. The UE may then transmit a plurality of SRS(s) to the multiple TRPs in accordance with the SRS configuration. Other aspects, features, and examples are also claimed and described.

Abstract: Methods, systems, and devices for wireless communications are described. A user equipment (UE) may transmit compressed interference information to a network entity. The UE may measure interference at the UE over a set of interference measurement resources. The UE may determine an interference distribution over the set of resources. The UE may encode the interference distribution using a compressions scheme which may reduce a payload or size of the interference distribution. The compression scheme may include compressing the distribution of the interference. Encoding the interference information may include generating a mean vector and a covariance matrix representative of the distribution of the interference measured over the given set of interference measurement resources. The UE may transmit the encoded interference information, and the network entity may decode the encoded interference information. The network entity may schedule communications with the UE based on the interference information.

Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a user equipment (UE) may determine, during a packet data convergence protocol (PDCP) reordering timer period, whether one or more packet transfer criteria are satisfied. The UE may transfer, during the PDCP reordering timer period, one or more packets from a reordering window based at least in part on a determination that the one or more packet transfer criteria are satisfied. Numerous other aspects are provided.

Abstract: In embodiments of systems and methods for managing end-to-end Quality of Service (QoS) in a communication path spanning a first communication network and a second communication network may include determining by a network element of the first communication network an end-to-end QoS requirement for communicating packets from a packet source to a packet destination via the communication path, determining by the network element a QoS provided by the second communication network within the communication path, and configuring the first communication network to provide sufficient QoS to support the end-to-end QoS requirement based on the QoS provided by the second communication network.

Abstract: Methods, systems, and devices for wireless communications are described. In some systems (e.g., non-orthogonal multiple access (NOMA) systems), a base station may serve a large number of user equipments (UEs) on the uplink. To improve detectability for these uplink transmissions (e.g., if reference signals are not available for the transmissions), the UEs may implement parallel transmissions of preambles with uplink data. A UE may split the uplink data into one or more data layers, and may select one or more preamble layers to transmit superposed with the data layers. These preambles may be sequences known to both the UE and the base station to aid in detectability. The UE may assign different signature sequences to each of these layers based on cross-correlation values (e.g., assigning sequences with higher cross-correlation values to the data layers for improved detectability), and may scramble the layers into a single shared signal for transmission.

Abstract: A method for wireless communication performed by a user equipment (UE) includes receiving, from a base station, a first indication to disable hybrid automatic repeat request (HARQ) feedback for a number of instances of a multicast transport block (TB). The method also includes receiving, from the base station, a second indication identifying a value of the number of instances of the multicast TB. The method further includes receiving, from the base station, one or more instances of the multicast TB. The method still further includes determining, based on the one or more received instances, whether the multicast TB is recoverable. The method further includes selectively transmitting, to the base station, HARQ feedback after all instances of the multicast TB have been transmitted by the base station based on the determination of whether the multicast TB is recoverable.

Abstract: Aspects presented herein may improve communications at high bandwidth or coverage limited scenarios, which may specify high transceiver energy efficiency and robustness to non-linear power amplifiers. In one aspect, a first network node transmits first information indicative of at least one of a modulation scheme or a modulation parameter to a second network node, where the modulation scheme is from a set of modulation schemes and the modulation parameter is associated with the modulation scheme, and where the set of modulation schemes includes one or more of: APSK, QAM, CPM, ceCPM, or MACPM. The first network node, from the second network node, second information indicative of at least one of the modulation scheme or the modulation parameter associated with the modulation scheme for at least one transmission.

Abstract: Aspects relate to an array antenna and communication using the array antenna. In some examples, the array antenna includes a first array of antenna elements arranged according to a first circle and a second array of antenna elements arranged according to a second circle, where the first circle and the second circle are concentric circles. In some examples, the first array of antenna elements is arranged with an angular offset with respect to the second array of antenna elements. For example, a first radius associated with a first antenna element of the first array of antenna elements may be offset at an angle with respect to a second radius of a second antenna element of the second array of antenna elements.
