Abstract
Methods, apparatuses, and systems are described for wireless communications. Cells may be grouped into a plurality of cell groups. A wireless device may transmit or drop one or more of a plurality of signals.
Claims79
A method comprising:
- transmitting, by a wireless device via a first cell of a first cell group and via a plurality of symbols of a time interval, a packet overlapping in time with a scheduled transmission of a sounding reference signal (SRS) via a second cell of the first cell group;
- and
- based on a determination that the wireless device is configured with multiple cell groups and a determination that a random access preamble is configured for transmission by the wireless device via a cell of a cell group different from the first cell group, transmitting the SRS.
A method comprising:
- transmitting, by a wireless device via a first cell of a cell group, a packet overlapping in time with a scheduled transmission of a sounding reference signal (SRS) via a second cell of the cell group;
- and
- based on a determination that the wireless device is configured with multiple cell groups and a determination that a random access preamble is not configured for transmission via the cell group by the wireless device in one or more symbols comprising a last symbol of a time interval, transmitting the SRS.
A method comprising:
- transmitting, by a wireless device via a first cell of a cell group, a packet overlapping in time with a scheduled transmission of a sounding reference signal (SRS) via a second cell of the cell group;
- and
- based on the wireless device not being configured with multiple cell groups, dropping the scheduled transmission of the SRS.
A wireless device comprising:
- one or more processors;
- and
- memory storing instructions that, when executed by the one or more processors, configure the wireless device to:
- transmit, via a first cell of a first cell group and via a plurality of symbols of a time interval, a packet overlapping in time with a scheduled transmission of a sounding reference signal (SRS) via a second cell of the first cell group;
- and
- based on a determination that the wireless device is configured with multiple cell groups and a determination that a random access preamble is configured for transmission by the wireless device via a cell of a cell group different from the first cell group, transmit the SRS.
