Abstract: Various aspects of the disclosure relate to use of a default communication configuration for cross carrier wireless communication. For example, a wireless communication device such as a user equipment (UE) may use a default communication configuration that includes quasi-colocation information (e.g., a default CORESET configuration) for communication on a secondary component carrier (SCC). The default communication configuration may be used, for example, in scenarios where a CORESET is not defined for the SCC and other configuration information is not available. For example, other configuration information might not be available due to a short time gap between a grant sent on a primary component carrier (PCC) and the communication on the SCC scheduled by the grant.

Abstract: Methods, systems, and devices for wireless communications are described that support configuration of aperiodic sounding reference signal transmission and triggering. A base station may transmit, within a first transmission time interval (TTI), a grant triggering a user equipment (UE) to transmit an aperiodic sounding reference signal (A-SRS), and may identify offset information indicating a TTI offset relative to the grant. The base station may determine a second TTI for the A-SRS based on the TTI offset. A UE may detect, within a first TTI, the grant triggering the UE to transmit the A-SRS, identify the offset information indicating the TTI offset relative to the grant, and determine the second TTI for transmitting the A-SRS based on the TTI offset. The UE may transmit the A-SRS in an SRS resource of the second TTI, and the base station may monitor the SRS resource of the second TTI for the A-SRS.

Abstract: A base station may identify an association between a set of physical cell identifiers (PCIs) identifying different transmission reception points (TRPs) and a set of transmission configuration indicator (TCI) states for a user equipment (UE). The base station may transmit a TCI state and PCI association indication to the UE. The UE may receive a downlink transmission using a receive beam associated with a TCI state, and may identify a PCI of the set of PCIs to use to decode the received downlink transmission. In cases where the TCI state used to receive the downlink transmission is associated with multiple PCIs, the UE may select a default PCI from the multiple PCIs, and may decode the received transmission accordingly. In some examples, the UE may receive reference signals from one or more of the serving TRPs and may identify a PCI to use to decode the received reference signals.

Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a user equipment may determine a transmission gap for a set of transmissions including a first type of transmission and a second type of transmission based at least in part on at least one of a sounding reference signal parameter, a numerology parameter, or an antenna parameter. In some aspects, the user equipment may transmit at least one transmission, the set of transmissions, in accordance with the transmission gap for the set of transmissions based at least in part on determining the transmission gap for the set of transmissions. Numerous other aspects are provided.

Abstract: In an aspect, a method of wireless communication includes receiving, by a user equipment (UE), downlink control information (DCI) having a resource allocation of allocated physical resource blocks (PRBs). The method additionally includes employing at least one of a) a wideband decoder, b) a wideband channel estimator, c) a bandwidth-specific decoder, or d) a bandwidth-specific channel estimator for wireless communications based at least on a feature of the resource allocation in the DCI. In other aspects a UE transmits, to a base station, an indication of UE capabilities regarding support of wideband physical resource group (PRG) for various transmission time interval (TTI) durations.

Abstract: Aspects herein describe increasing density of reference signal transmissions in wireless communications. A plurality of reference signal configurations, each indicating resource elements for one or more antenna ports over which reference signals for the one or more antenna ports are scheduled for transmission, can be received. An association configuration indicating an association between at least two antenna ports as having similar channel characteristics can also be received. A plurality of reference signals can be received in the resource elements corresponding to the at least two antenna ports as indicated in the at least two of the plurality of reference signal configurations, which can be used to perform a channel measurement of the similar channel characteristics of channels of the at least two antenna ports over at least a portion of the plurality of reference signals.

Abstract: Aspects are provided allowing UEs with non-coherent or partially coherent antennas to re-interpret TPMI received in DCI into a set of TPMIs corresponding to different subbands. The UE receives a TPMI associated with at least one first antenna and at least one second antenna which are non-coherent with each other, and the UE determines a set of TPMIs including a first and second TPMI based on the received TPMI. The set of TPMIs include at least one TPMI different from the received TPMI. The UE transmits, based on the first TPMI, from the at least one first antenna within at least one first subband. The UE also transmits, based on the second TPMI, from the at least one second antenna within at least one second subband different from the at least one first subband. Thus, full power transmission based on re-interpreted TPMI with reduced DCI overhead may result.

Abstract: Disclosed are techniques to determine angle of departure (AoD) of signals transmitted from a set of transmission points associated with a transmitter (e.g., a base station, a user equipment (UE)). In an aspect, the set of transmission points are collocated and transmit coherent signals. A receiver (e.g., UE, network entity) determines phase difference of arrivals (PDoAs) of the signals. Based on the PDoAs and locations of the set of transmission points, the AoD can be calculated. When the UE is the receiver, the network entity can send a base station almanac (BSA) message to the UE indicating the set of transmission points and their locations.

Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a user equipment (UE) may receive information configuring one or more occasions of a periodic channel state information reference signal (P-CSI-RS) without associated quasi co-location (QCL) information for the one or more occasions of the P-CSI-RS. The UE may receive an occasion of the P-CSI-RS, of the one or more occasions of the P-CSI-RS, using a QCL relation determined based at least in part on whether a physical downlink shared channel (PDSCH) is scheduled for a same set of symbols as the occasion of the P-CSI-RS. Numerous other aspects are provided.
