摘要： An embodiment method, by a user equipment (UE), includes performing a channel measurement (CM) on a first subset of a set of non-zero-power (NZP) CSI reference signal (CSI-RS) resources and an interference measurement (IM) on at least a second subset of the set of NZP CSI-RS resources. The second subset includes one or more NZP CSI-RS ports. The IM is performed according to assumptions: each NZP CSI-RS port in the second subset corresponds to an interference transmission layer, the IM being in accordance with a set of energy per resource element ratios each associated with one NZP CSI-RS resource in the second subset; and other interference not associated with the interference transmission layers is on the first and second subsets. The method includes generating a channel state information (CSI) report based on the CM and IM and transmitting the CSI report to a network.

摘要： In an embodiment, a user equipment (UE) receives, from an access node (AN), downlink control information (DCI) triggering a transmission of a sounding reference signal (SRS) of a SRS resource set. The DCI indicates a time-domain resource in available time-domain resources for transmitting the SRS resource set. The UE determines a position of the time-domain resource in the available time-domain resources based on the DCI, and transmits the SRS in accordance with the position of the time-domain resource. In another embodiment, a UE receives control information indicating a frequency resource in a carrier for transmission of one or more SRSs. The UE determines, based thereon, to segment the frequency resource into segments that each includes contiguous physical resource blocks (PRBs), and transmits a SRS in an orthogonal frequency division multiplexing (OFDM) symbol on a first segment and not on a second segment.

摘要： Example wireless communication methods and apparatus are described. One example includes receiving first configuration information of a bandwidth part (BWP) in a carrier for a serving cell by a user equipment (UE). The first configuration information includes a first group of parameters and a first resource group (RG) on the BWP in the carrier for the serving cell. The UE receives second configuration information of the BWP in the carrier, where the second configuration information includes a second group of parameters and a second RG on the BWP in the carrier. Transmission or reception associated with the first RG is performed based on the first group of parameters. Transmission or reception associated with the second RG is performed based on the second group of parameters.

摘要： A network controller may transmit, to a communication device, information about a portion of a sounding reference signal (SRS) bandwidth, where the SRS bandwidth has been configured for the communication device for transmitting a SRS resource set via radio resource control (RRC) signaling. The communication device may then transmit the SRS resource set in the portion of the SRS bandwidth, upon being triggered by a downlink control information (DCI) message. The information about the portion of the SRS bandwidth may be transmitted in a DCI message or a medium access control (MAC) control element (CE).
