Abstract
A method, network node and wireless device (WD) and apparatus for power control for multiple channels and power prioritization are disclosed. According to one aspect, a method in a network node includes determining a first WD-specific power limit for each cell c of a cell group that includes at least one primary cell, PCell, and up to N secondary cells, SCells, N being a non-negative integer. The method also includes transmitting an indication of the first WD-specific power limit.
Claims26
A network node configured to communicate with a wireless device, WD, the network node comprising:
- processing circuitry configured to determine a first WD-specific power limit for each cell c of a cell group that includes at least one primary cell, PCell, and up to N secondary cells, SCells, N being a non-negative integer;
- a radio interface in communication with the processing circuitry, the radio interface configured to transmit an indication of the first WD-specific power limit;
- and
- the processing circuitry being further configured to determine a first cell-specific power limit, PMax, that applies to all WDs within a cell, each WD configured to use the PCell and the up to N SCells.

A wireless device, WD, configured to communicate with a network node, the WD comprising:
- a radio interface configured to receive a first WD-specific power limit for each cell c of a cell group that includes at least one primary cell, PCell, and up to N secondary cells, SCells, N being a non-negative integer;
- processing circuitry in communication with the radio interface, the processing circuitry configured to:
- determine a first maximum power for a cell c, PCMAX,ƒ,c(i) in the cell group, based at least in part on the first WD-specific power limit;
- limit a transmit power of the WD based at least in part on the first maximum power for a cell, PCMAX,ƒ,c(i);
- cause transmission of one or more uplink channels in one or more of the cells in the cell groups using the determined limited transmit power;
- and
- the radio interface being further configured to receive a first cell-specific power limit, PMax, that applies to all WDs within a cell, each WD configured to use the PCell and the up to N SCells and PCMAX,ƒ,c(i), being further based at least in part on the first cell-specific power limit, PMax.
