Abstract
Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a user equipment (UE) may receive an indication of a mapping of port numbers to sounding reference signal (SRS) resources of a first resource set and a second resource set, where port numbers of the first resource set and port numbers of the second resource set are uniquely indicated. The UE may transmit an uplink communication based at least in part on the indication. Numerous other aspects are described.
Claims30
A user equipment (UE) for wireless communication, comprising:
- one or more memories;
- and
- one or more processors, coupled to the one or more memories, configured to:
- receive a first sounding reference signal (SRS) resource indicator (SRI) that includes:
- a first mapping of first antenna port numbers to first SRS resources of a first SRS resource set, and
- an indication of a first set of layers associated with the first SRS resources;
- receive a second SRI that includes:
- a second mapping of second antenna port numbers to second SRS resources of a second SRS resource set, wherein the first antenna port numbers of the first SRS resource set are mutually exclusive from the second antenna port numbers of the second SRS resource set, and
- an indication of a second set of layers associated with the second SRS resources;
- and
- transmit an uplink communication based at least in part on the first SRI or the second SRI.
A network node for wireless communication, comprising:
- one or more memories;
- and
- one or more processors, coupled to the one or more memories, configured to:
- transmit a first sounding reference signal (SRS) resource indicator (SRI) that includes:
- a first mapping of first antenna port numbers to first SRS resources of a first SRS resource set, and
- an indication of a first set of layers associated with the first SRS resources;
- transmit a second SRI that includes:
- a second mapping of second antenna port numbers to second SRS resources of a second SRS resource set, wherein the first antenna port numbers of the first SRS resource set are mutually exclusive from the second antenna port numbers of the second SRS resource set, and
- an indication of a second set of layers associated with the second SRS resources;
- and
- receive, from a user equipment (UE), an uplink communication based at least in part on the first SRI or the second SRI.
A method of wireless communication performed by a user equipment (UE), comprising:
- receiving a first sounding reference signal (SRS) resource indicator (SRI) that includes:
- a first mapping of first antenna port numbers to first SRS signal (SRS)-resources of a first SRS resource set, and
- an indication of a first set of layers associated with the first SRS resources;
- receiving a second SRI that includes:
- a second mapping of second antenna port numbers to second SRS resources of a second SRS resource set, wherein the first antenna port numbers of the first SRS resource set are mutually exclusive from the second antenna port numbers of the second SRS resource set, and
- an indication of a second set of layers associated with the second SRS resources;
- and
- transmitting an uplink communication based at least in part on the first SRI or the second SRI.
A method of wireless communication performed by a network node, comprising:
- transmitting a first sounding reference signal (SRS) resource indicator (SRI) that includes:
- a first mapping of first antenna port numbers to first SRS resources of a first SRS resource set, and
- an indication of a first set of layers associated with the first SRS resources;
- transmitting a second SRI that includes:
- a second mapping of second antenna port numbers to second SRS resources of a second SRS resource set, wherein the first antenna port numbers of the first SRS resource set are mutually exclusive from the second antenna port numbers of the second SRS resource set, and
- an indication of a second set of layers associated with the second SRS resources;
- and
- receiving, from a user equipment (UE), an uplink communication based at least in part on the first SRI or the second SRI.
