Abstract
A user equipment, UE, is configured to receive downlink control information, DCI, transmitted to the UE by a primary cell in a wireless communication system. The UE comprises one or more processing circuits that shall assume that a DCI message which has a common payload size and the same first control channel element index, but different bit fields, in a common search space and a UE-specific search space is transmitted by the primary cell in the common search space or the UE-specific search space, based on radio resource control, RRC, configuration of the UE.
Claims10
A method implemented by a user equipment (UE) for receiving a downlink control information (DCI) message transmitted to the UE by a primary cell in a wireless communication system, the method comprising:
- monitoring control channel candidates with cyclic redundancy check (CRC) scrambled by a radio network temporary identity (RNTI) for the UE, wherein the DCI message has a common payload size and the same first control channel element (CCE) index, but with different sets of DCI information fields, as defined in a common search space and a UE-specific search space on the primary cell;
- and
- assuming that, for the control channel candidates, only the control channel in the common search space or only the control channel in the UE-specific search space is transmitted by the primary cell, depending on a radio resource control (RRC) configuration of the UE.
