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.

Abstract: Methods, systems, and devices for wireless communications are described. Generally, the described techniques provide for a device such as a user equipment (UE), a base station, or both, to perform a channel noise and interference estimation based on a set of null resources in a data channel. The device may identify a first configuration for a set of demodulation reference signals (DMRSs) in a first set of time periods of a data channel and a second configuration for a set of null resources in a second set of time periods of the data channel. The second set of time periods may be nonoverlapping with the first set of time periods. The device may perform a channel estimation procedure on the data channel based on the null resources and the DMRS resources. The device may process data received via resources of the data channel based on the channel estimation procedure.

Abstract: Methods, systems, and devices for wireless communications are described. A user equipment (UE) may receive, from a base station, a channel state information (CSI) configuration indicating a first feedback reporting periodicity for a dominant, or strong, spatial layer and a second feedback reporting periodicity for a non-dominant, or weak, spatial layer. The UE may transmit a first CSI report for at least the dominant spatial layer according to the first feedback reporting periodicity. The UE may transmit a second CSI report for the non-dominant spatial layer according to the second feedback reporting periodicity. In some cases, for aperiodic reporting, the UE may be triggered by downlink control information to report CSI for the dominant spatial layer. In some cases, the CSI configuration may indicate different codebooks for the dominant and non-dominant spatial layers.

Abstract: Methods, systems, and devices for wireless communications are described. In some systems, a user equipment (UE) may transmit, to a base station, a UE capability message indicating support for at least a first demodulation mode or a second demodulation mode. The first demodulation mode may correspond to a single demodulation procedure associated with a set of antenna ports at the UE, and the second demodulation mode may correspond to multiple demodulation procedures, each procedure associated with a respective subset of antenna ports at the UE. In some cases, the UE may flexibly switch between demodulation modes. The UE may receive, from the base station, one or more downlink signals via one or more downlink beams based on the indication of the first demodulation mode or the second demodulation mode. The UE may demodulate the one or more downlink signals based on the indicated (e.g., an active) demodulation mode.

Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a user equipment (UE) may receive downlink control information (DCI) that includes an uplink grant indicating information relating to multiple transport blocks for an uplink transmission, the information indicating which of the multiple transport blocks is to be transmitted. The UE may transmit one or more of the multiple transport blocks in accordance with the DCI. Numerous other aspects are described.

Abstract: Aspects relate to sounding on a subset of available sounding resources. A user equipment (UE) may transmit a sounding reference signal (SRS) on a subset of the frequency resources available for a hop of an SRS hopping sequence. A UE may be configured to use a subset of frequency resources or the UE may autonomously identify this subset. A base station may send a bit map to a UE to indicate the subset of resources to use for a hop. Each bit of the bit map may indicate that the UE is to transmit an SRS on a particular RB or on a particular groups of RBs. The same subset of resources may be designated for each hop or different subsets of resources may be designated for different hops. An indication of the subset of resources may be provided for each hop. The subset of resources may be cycled for different hops.

Abstract: Aspects relate to wireless communication for slot postponing of aperiodic sound reference signals (A-SRS) by a user equipment in a wireless network. A network node, such as a gNodeB, may send at least a portion of a slot postponing configuration for transmission of aperiodic sounding reference signals (A-SRSs) to a user equipment (UE). In a particular aspect, the slot postponing configuration is established through RRC signaling and does not utilize downlink control information (DCI) or MAC-CE sent parameters for establishing the slot postponing configuration. The slot positioning configuration is used to control slot offset postponing, the number of slot offsets, the number of times transmission of A-SRS can be postponed in the UE, and priority rules based on the postponing configuration.

Abstract: Techniques related to multiplexing uplink control information (UCI) onto a multi-transport block (TB) physical uplink shared channel (PUSCH) transmission are disclosed. Some aspects of the disclosure relate to devices and methods for wireless communication where a user equipment (UE) receives an uplink grant for a PUSCH transmission having a plurality of TBs, each being associated with a respective TB priority index. The UE then transmits the PUSCH including the plurality of TBs. The UE may further transmit a plurality of UCIs multiplexed with the PUSCH, where each UCI is associated with a respective UCI priority index. Other aspects, embodiments, and features are also claimed and described.

Abstract: Methods, systems (100), and devices for wireless communications are described. In some systems (100), a base station (105) and a user equipment (UE) (115) may communicate over a shared radio frequency spectrum and may employ time-division multiplexing (TDM) techniques to multiplex sensing signals (315) with wireless communications in the shared radio frequency spectrum. In some examples, the base station (105) may configure the UE (115) with a first retuning gap during which the UE (115) may retune a radio frequency chain of the UE (115) when transitioning from a sensing signal (315) pulse to wireless communications and with a second retuning gap during which the UE may retune the radio frequency chain when transitioning from wireless communications to a sensing signal (315). In some other examples, the base station (105) may configure the UE (115) with a phase and amplitude continuity status of multiple adjacent sensing signal (315) pulses that may indicate whether the multiple adjacent sensing signal (315) pulses have
