Abstract: Aspects of the disclosure relate to a wireless user equipment (UE) configured to receive a downlink in a network configured for full duplex communication. The UE receives from the network an indication of a maximum rank of an uplink from an interfering, aggressor UE. The UE measures interference of a signal from the aggressor UE, and based on the measurement, determines one or more rank values for the aggressor UE, less than or equal to the maximum rank. The UE may further determine one or more channel parameters for downlink transmissions the UE receives, corresponding to the determined rank values. The UE then transmits a channel state information (CSI) report that includes an indication of at least one of the one or more rank values for the aggressor UE. The CSI report may further include the determined channel parameters. Other aspects, embodiments, and features are also claimed and described.

Abstract: Aspects of the present disclosure disclose techniques for the indication of the allocation of the downlink (DL) demodulation reference signal (DM-RS) ports for the data channel in NR communications. In some examples, the channel state information (CSI) reference signal (CSI-RS) may be associated with a corresponding DM-RS for a DL data channel. The transmitting device, in some examples, may further transmit a notification that provides resource allocations (e.g., port allocations) that minimize the redundant information that is required to be transmitted from the base station to the user equipment (UE) when the DM-RS port allocation is the same as the CSI-RS port allocation received by the UE in an earlier time slot.

Abstract: Methods, systems, and devices for wireless communications are described. A user equipment (UE) may transmit a UE capability message, the UE capability message indicating a supported transmit antenna switching (TxAS) capability for each port of the UE. The UE may receive a configuration message indicating an uplink multiple-input/multiple-output (UL MIMO) configuration for the UE, the UL MIMO configuration being based at least in part on the UE capability message. The UE may identify, based at least in part on the configuration message, a sounding reference signal (SRS) configuration to use for transmitting SRSs in conjunction with the UL MIMO communications, the SRS configuration comprising a configuration for transmission by the UE of SRSs using at least one of the two or more ports of the UE, the SRSs transmitted on one or more antennas of the UE selected according to a TxAS configuration for the respective port.

Abstract: Certain aspects of the present disclosure provide techniques for indicating a purpose for a reference signal. According to certain aspects, a method of wireless communication by a user equipment (UE) is provided. The method generally includes receiving an indication of a purpose of a reference signal (RS) from a base station (BS) and processing the RS in accordance with the indicated purpose.

Abstract: Wireless communication that includes transmission, reception, and configuration of a CSIRS with a configurable band-width is discussed. A base station/gNB may determine a number of antenna ports to be used for wireless communication. The base station/gNB may allocate a first plurality of frequency resources for the transmission of the CSIRS based on the determined number of antenna ports, and may transmit the CSIRS over the first plurality of frequency resources. A mobile device may receive the CSIRS over the first plurality of frequency resources and estimate at least one of channel quality and interference associated with the first plurality of frequency resources based on the received CSIRS.

Abstract: Reporting aperiodic channel state information (A-CSI) via a physical uplink control channel (PUCCH) is disclosed. A UE receives a configuration to report aperiodic channel state information (A-CSI) using physical uplink control channel (PUCCH). The UE can report lightweight A-CSI via short/long PUCCH or may report heavy A-CSI via short/long PUCCH. The UE receives a trigger signal for PUCCH-based A-CSI reporting either by a dedicated downlink grant or by a group common DCI. When triggered via a DCI-based trigger, the PUCCH resource can be either a resource used for HARQ-ACK feedback, e.g., short PUCCH; or a semi-static configured PUCCH resource, e.g., either short PUCCH or long PUCCH. When triggered via a group common DCI-based trigger, the PUCCH resource can be either semi-statically configured, or dynamically indicated.

Abstract: Methods, systems, and devices for wireless communication are described. Generally, the described techniques provide for communicating an uplink grant and a channel state information reference signal (CSI-RS) trigger. A wireless device may identify e a pending collision for a slot of a carrier between a CSI-RS and uplink data. The wireless device may determine a communication configuration for the CSI-RS and the uplink data such that no collision occurs. The determined communication configuration for the CSI-RS may include delaying one of the colliding signals, transmitting only one of the colliding signals and suppressing the other, or reconfiguring the slot such that both signals can be transmitted successfully. Additionally, the UE and the base station may determine a CSI reporting configuration based on the determined communication configuration.

Abstract: A signaling design for multiple aperiodic channel state information (M-A-CSI) feedback is disclosed. In new radio (NR) networks, there may be scenarios where M-A-CSI are triggered and reported simultaneously. Timing issues may arise because of the different delay periods for difference CSI processes and reporting. In a first aspect, a general set of delay times for the M-A-CSI maybe signaled to the user equipment (UE) from which a candidate set is selected by the UE based on various CSI related settings. An indication from the base station may then be used to select the delay from the candidate set. In a second aspect, a delay period may be selected from the set of delays associated with and corresponding to the M-A-CSI.

Abstract: In one embodiment, enhanced packet flow monitoring is performed by packet switching devices in a network. A packet switching device is configured to monitor a flow of packets passing through the packet switching device, including detecting a gap in consecutive packets of the flow of packets, and attributing the gap as not being dropped one or more packets based on a particular time duration between a last received packet of the flow of packets before said detected gap and a first received packet of the flow of packets after said detected gap. In one embodiment, the gap is attributed to not being dropped packets when the particular time duration is greater than a threshold value; and conversely, attributed to being dropped packets when the particular time duration is less than a same or different threshold value.
