Abstract
A base station may select an active set of serving cells for a user equipment (UE) from a configured cell set of the UE. The base station may select a cell of the active set of serving cells to perform a primary cell (PCell) function for the UE. The base station may select the cell and transmit an indication of the selected cell to the UE in layer 1 or layer 2 signaling, or the base station may select the cell using a common rule and the UE may select the cell using the common rule. Upon determining the cell, the UE may perform the PCell function with the cell.
Claims30
A method of wireless communication at a user equipment (UE), comprising:
- determining an active set of serving cells from a configured cell set;
- determining a cell of the active set of serving cells configured to perform a primary cell (PCell) function for the UE based on layer 1 or layer 2 signaling from a base station or based on a common rule;
- and
- performing the PCell function with the determined cell.
An apparatus for wireless communication at a user equipment (UE), comprising:
- a memory;
- and
- at least one processor coupled to the memory and configured to:
- determine an active set of serving cells from a configured cell set;
- determining a cell of the active set of serving cells configured to perform a primary cell (PCell) function for the UE based on layer 1 or layer 2 signaling from a base station or based on a common rule;
- and
- perform the PCell function with the determined cell.
A method of wireless communication at a base station, comprising:
- determining an active set of serving cells for a user equipment (UE) from a configured cell set for the UE;
- selecting a cell from the active set of serving cells to perform a primary cell (PCell) function for the UE based on a common rule, or selecting the cell from the active set of serving cells to perform the PCell function for the UE and transmitting an indication of the cell to the UE through layer 1 signaling;
- and
- configuring the cell to perform the PCell function for the UE.
