USER EQUIPMENTS, BASE STATIONS AND METHODS FOR LICENSE ASSISTED ACCESS (LAA)

摘要

A user equipment (UE) is described. The UE receives an RRC message for configuration of a first serving cell, an RRC message for configuration of a second serving cell and an RRC message for configuration of cross-carrier scheduling for the second serving cell. The UE also monitors a first EPDCCH scheduling a first PDSCH in a subframe on the first serving cell on the basis of a first EPDCCH starting position and to monitor a second EPDCCH scheduling a second PDSCH in the subframe on the first serving cell on the basis of a second EPDCCH starting position. The UE further receives the first PDSCH on the first serving cell, if the first EPDCCH is detected, and receives the second PDSCH on the second serving cell, if the second EPDCCH is detected.

主权项

1. A user equipment (UE) comprising:
a higher layer processor configured to receive a radio resource control (RRC) message for configuration of a first serving cell, an RRC message for configuration of a second serving cell and an RRC message for configuration of cross-carrier scheduling for the second serving cell; a physical downlink control channel receiver configured to monitor a first enhanced physical downlink control channel (EPDCCH) scheduling a first physical downlink shared channel (PDSCH) in a subframe on the first serving cell on the basis of a first EPDCCH starting position and to monitor a second EPDCCH scheduling a second PDSCH in the subframe on the first serving cell on the basis of a second EPDCCH starting position; and a physical downlink shared channel receiver configured to receive the first PDSCH on the first serving cell, if the first EPDCCH is detected, and to receive the second PDSCH on the second serving cell, if the second EPDCCH is detected; wherein:
the first EPDCCH starting position is one of an initial number of OFDM symbols within the subframe, andthe second EPDCCH starting position is an OFDM symbol other than the initial number of OFDM symbols within the subframe.
