Abstract

Wireless communications are described. A wireless device and/or a base station may determine/select one or more beams for transmission of signals (e.g., sounding reference signals, SRSs) in one or more cells. The wireless device and/or the base station may determine/select a beam based on one or more of: cell indicators of a first cell and/or a second cell, antenna panel indicators associated with SRS transmissions, priorities of SRS transmissions, resource set indicators corresponding to the SRS transmissions, and/or other information.

Claims (90)

1 . A method comprising:

triggering:

a first sounding reference signal (SRS) transmission via a first SRS resource of a first cell;

a second SRS transmission via a second SRS resource of the first cell; and

a third SRS transmission via a third SRS resource of a second cell, wherein the first SRS resource, the second SRS resource, and the third SRS resource overlap in at least one symbol; and

transmitting:

the first SRS transmission via a first spatial domain filter based on the first SRS resource;

the second SRS transmission via a second spatial domain filter based on the second SRS resource; and

the third SRS transmission via the first spatial domain filter, wherein the first spatial domain filter is used for the third SRS transmission based on a first SRS resource index of the first SRS resource being lower than a second SRS resource index of the second SRS resource.

2 . The method of claim 1 , wherein the first spatial domain filter is used for the third SRS transmission based on:

the first SRS resource index of the first SRS resource being lower than the second SRS resource index of the second SRS resource; and

a first cell index of the first cell being lower than a second cell index of the second cell.

3 . The method of claim 2 , wherein:

an SRS transmission type of the first SRS transmission and an SRS transmission type of the second SRS transmission are the same; and

each of the SRS transmission type of the first SRS transmission and the SRS transmission type of the second SRS transmission is:

an aperiodic SRS transmission;

a semi-persistent SRS transmission; or

a periodic SRS transmission.

4 . The method of claim 1 , wherein:

SRS transmission types of the first SRS transmission and the second SRS transmission are different; and

the SRS transmission types comprise any two of:

aperiodic SRS transmissions;

semi-persistent SRS transmissions; and

periodic SRS transmissions.

5 . The method of claim 4 , wherein the first spatial domain filter is used for the third SRS transmission based on a priority of an SRS transmission type of the first SRS transmission being higher than a priority of an SRS transmission type of the second SRS transmission.

6 . The method of claim 5 , wherein a priority of the semi-persistent SRS transmissions is:

lower than a priority of the aperiodic SRS transmissions; and
