Abstract
A User Equipment (UE) configured for multi-group communications is described. The UE includes a processor and instructions stored in memory that is in electronic communication with the processor. The UE detects a plurality of cells. The UE also determines to use multiple groups of one or more cells. The UE further determines a primary secondary cell (PSCell) for a non-primary cell (non-PCell) group based on UE-specific radio resource control (RRC) signaling. The UE additionally receives information using the multiple groups.
Claims4
A User Equipment (UE), comprising:
- a computer processor;
- a memory in electronic communication with the computer processor;
- instructions stored in the memory, the instructions being executable by the computer processor to:
- receive, from a base station, a radio resource control, RRC, message including a configuration to configure multiple groups, each of which is constituted by one or more serving cells;
- wherein
- a serving cell which is included in one group of the multiple groups is a primary cell (PCell), and
- a serving cell is included in another group of the multiple groups is a specific cell,
- decode a physical downlink control channel (PDCCH) with a cyclic redundancy check (CRC) scrambled by a first random access radio network temporary identifier (RA-RNTI) in a common search space on the PCell;
- and
- decode a physical downlink control channel (PDCCH) with a cyclic redundancy check (CRC) scrambled by a first random access radio network temporary identifier (RA-RNTI) in a common search space on the specific cell.
