Abstract
The embodiments of the present invention provide a transmission and reception mechanism for a downlink control channel applicable to a narrowband MTC UE, and a base station and a user equipment for executing the mechanism. The method according to the embodiment of the present invention includes: determining an MPDCCH-PRB-set and determining a set of MPDCCH candidates in the determined MPDCCH-PRB-set according to an aggregation level, wherein a number of PRB-pairs in the MPDCCH-PRB-set is 2, 4 or 6; and monitoring the MPDCCH in the determined set of MPDCCH candidates to obtain downlink control information for an MTC UE.
Claims4
A User Equipment (UE), comprising:
- a reception unit to monitor Machine Type Communication (MTC) Physical Downlink Control CHannel (MPDCCH) candidates at an aggregation level of 24 when a first parameter is configured by higher layers, wherein
- the first parameter indicates a MPDCCH Physical Resource Block (PRB) set with 6 PRB-pairs,
- a number of the MPDCCH candidates is defined for each aggregation level and each repetition level, and
- the repetition level is allocated for each of the common search space and the UE-specific search space of the MPDCCH.
An evolved NodeB (eNB), comprising:
- a transmission unit to transmit monitor Machine Type Communication (MTC) Physical Downlink Control CHannel (MPDCCH) on one of MPDCCH candidates at an aggregation level of 24 when a first parameter is configured by higher layers, wherein
- the first parameter indicates a MPDCCH Physical Resource Block (PRB) set with 6 PRB-pairs,
- a number of the MPDCCH candidates is defined for each aggregation level and each repetition level, and
- the repetition level is allocated for each of the common search space and the User Equipment (UE)-specific search space of the MPDCCH.
