COMMUNICATIONS METHOD, BASE STATION, AND MOBILE TERMINAL

摘要

A mobile terminal monitors a candidate set (Candidate Set) of L1/L2 control information. However, when a base station carries out signaling of a candidate set to each of all mobile terminals, the load on the base station from the viewpoint of radio resources becomes large. Furthermore, the amount of processing in performing a blind detection of each mobile terminal also increases.;Therefore, the base station carries out a process of performing grouping of the above-mentioned mobile terminal which is a destination of transmission of the above-mentioned L1/L2 control signal, a process of allocating an L1/L2 control signal to be transmitted to a predetermined mobile terminal to the control channel elements included in a group to which the predetermined mobile terminal is belonging on the basis of attribution information about the mobile terminal. The mobile terminal receives a downlink physical control channel, and also performs a blind detection process on the candidate set corresponding to the group to which the mobile terminal is belonging and performs a process of reading the L1/L2 control signal from the control channel elements included in the candidate set.

主权项

1. A communications method which is implemented by a communications system including a base station that carries out communications using a plurality of frequency bands, and a mobile terminal that carries out a detection of a candidate set including control channel elements which are used for transmission of an L1/L2 control signal from said base station, and each of which is one of regions to which one said frequency band is divided, so as to receive said L1/L2 control signal, said communications method comprising:
a process of grouping said mobile terminal which is a destination of transmission of said L1/L2 control signal on a basis of attribution information of said mobile terminal; and a process of performing a detection process on said candidate set corresponding to the group to which said mobile terminal is belonging, and reading said L1/L2 control signal from the control channel elements included in said candidate set.
