Embodiment Construction

[0032] Here, first, the first embodiment of the present invention will be described in detail.

[0033] In this embodiment, the current EREG grouping is kept: 16 EREGs form a PRB pair: EREG#0 to EREG#15. An ECCE has 4 EREGs, which can be one of the following: {EREG#0,4,8,12},{EREG#1,5,9,13}, {EREG#2,6,10,14} ,{EREG#3,7,11,15}.

[0034] In order to meet the following goals: the EREGs that form distributed ECCEs are evenly distributed in the bandwidth of the entire 6 PRBs, the following configurations are made in the present invention:

[0035] by serial number The number in the PRB pair is EREG to form an ECCE numbered n;

[0037]

[0038] is used to indicate the number of EREGs in each ECCE and is 4;

[0039] Used to indicate EPDCCH-PRB-set X m the number of PRB pairs included, and is 6; and

[0040] It is used to indicate the number of ECCEs in each PRB pair and is 4.

Abstract

The invention discloses two methods and devices for configuring an ECCE-EREG mapping relation in a communication system based on machine type communication, and a method and device for performing blind test on downlink control information in a communication system based on a machine type communication. According to an embodiment, the method for configuring the ECCE-EREG mapping relation in a communication system based on machine type communication comprises steps of A configuring ECCE to comprise 3 EREGs and performing ECCE-EREG mapping based on an EPDCCH transmission mode. Based on a condition that a current EPDCCH-PRB-set only supports 2,4,8 PRB pairs, the EPDCCH-PRB-set having 6 PRB pairs can be effectively utilized by a low complex MTC UE, and cost for distributing the PRB pairs is avoided. Besides, the configuration can realize scheduling of DCI having more flexibility, and is applicable to supporting higher aggregation level level used for Rel-13MTC UE.

Description

technical field [0001] The present invention relates to a communication system, in particular to a method for configuring an ECCE-EREG mapping relationship in a machine-type communication-based communication system and a corresponding blind detection method. Background technique [0002] In Release 13, a low-complexity machine type communication user equipment (Machine Type Communication User Equipment) was approved. These MTC UEs only need to support 1.4MHz radio frequency bandwidth in uplink and downlink (that is, there are only 6 physical resource block pairs (PRB pairs)), and at the same time, they should meet the coverage enhancement of 15dB. [0003] In order to meet the above coverage enhancement requirements, the enhanced downlink control channel (EPDCCH) needs to repeatedly transmit downlink control information (DCI) in multiple subframes. This results in a decrease in UE efficiency. [0004] In order to improve UE efficiency and reduce power consumption, the enha...
