Abstract
Methods, systems, and apparatuses are described for wireless communications. Cells may be grouped into a plurality of cell groups. If a first signal is configured for transmission via a first cell of a first cell group in parallel with a transmission of a second signal via a second cell of a second cell group, a wireless device may drop, or adjust transmission power of, at least one of the first signal or the second signal.
Claims39
A method comprising:
- receiving, by a wireless device, configuration parameters of a plurality of cells grouped into a plurality of cell groups;
- adjusting a transmission power of a transmission of a transport block via a first cell of a first cell group, such that an allowable transmission power is satisfied for transmissions where a first random access preamble (RAP) via a second cell of a second cell group overlaps with the transmission of the transport block;
- dropping a sounding reference signal (SRS), wherein:
- the SRS is configured for transmission via a third cell of the first cell group in parallel with a transmission of a second RAP via the second cell, and
- a calculated total transmission power of the wireless device exceeds the allowable transmission power for transmissions where the second RAP overlaps with the SRS;
- and
- transmitting, via the second cell, at least one of the first RAP or the second RAP.

A method comprising:
- transmitting, by a base station and to a wireless device, configuration parameters of a plurality of cells grouped into a plurality of cell groups;
- adjusting a transmission power of a transmission of a transport block via a first cell of a first cell group, such that an allowable transmission power is satisfied for transmissions where a first random access preamble (RAP) via a second cell of a second cell group overlaps with the transmission of the transport block;
- dropping a sounding reference signal (SRS), wherein:
- the SRS is configured for transmission via a third cell of the first cell group in parallel with a transmission of a second RAP via the second cell, and
- a calculated total transmission power of the wireless device exceeds the allowable transmission power for transmissions where the second RAP overlaps with the SRS;
- and
- transmitting, by the wireless device, to the base station, via the second cell, at least one of the first RAP or the second RAP.
4 more elements
A wireless device comprising:
- one or more processors;
- and
- memory storing instructions that, when executed by the one or more processors, cause the wireless device to:
- receive configuration parameters of a plurality of cells grouped into a plurality of cell groups;
- adjust a transmission power of a transmission of a transport block via a first cell of a first cell group, such that an allowable transmission power is satisfied for transmissions where a first random access preamble (RAP) via a second cell of a second cell group overlaps with the transmission of the transport block;
- drop a sounding reference signal (SRS), wherein:
- the SRS is configured for transmission via a third cell of the first cell group in parallel with a transmission of a second RAP via the second cell, and
- a calculated total transmission power of the wireless device exceeds the allowable transmission power for transmissions where the second RAP overlaps with the SRS;
- and
- transmit, via the second cell, at least one of the first RAP or the second RAP.
