Method of blind decoding of control channel for a wireless communication system

摘要

A method of blind decoding of a control channel for a wireless communication system comprising a network and a mobile device is disclosed. The network selects at least one of a plurality of control channels of at least one logical domain of control channel element, for transmitting control information to the mobile device, wherein the plurality of control channels of each logical domain are uniformly distributed over the logical domain. On the other side, the mobile device monitors all of the control channel candidates of each of the at least one logical domain of control channel element, for obtaining the control information which is transmitted from the network and configured to the mobile device, wherein all of the control channel candidates of each logical domain are uniformly distributed over the logical domain.

1. A method of blind decoding of a control channel for a mobile device of a wireless communication system comprising a network and the mobile device, the method comprising:
monitoring all of enhanced physical downlink control channel (EPDCCH) candidates at an ECCE (enhanced control channel elements) domain, wherein the EPDCCH candidates are in a position derived from the following equation:L⁢{(Yκ+⌊m*NECCE,k/LM(L)⌋)⁢mod⁢⌊NECCE,k/L⌋}+i, where the NECCE,k is the total number of ECCE in the ECCE domain of a subframe k; m denotes the mth EPDCCH candidate and m has a value range from 0 to M(L)−1; M(L)is the total number of EPDCCH candidates of a corresponding aggregation level L for the ECCE domain; i denotes the index of ECCE of the mth EPDCCH candidate and i has a value range from 0 to L−1; and Yk is a pseudo-random number.
