Problems solved by technology

[0006] The present invention provides a method and a base station for determining the number of MPDCCH repetitions, which are used to solve the problem that in the prior art, when the base station uses the MPDCCH repetition times sent by the core network to send paging messages, the MPDCCH used when sending paging messages will appear repeatedly. Excessive number of times, waste of system resources

Embodiment Construction

[0059] The base station in the embodiment of the present invention obtains the initial MPDCCH repetition number used by the user equipment; wherein, the initial MPDCCH repetition number is the MPDCCH repetition number used when the user equipment accesses the network last time, or the user equipment enters from the connected state The last MPDCCH repetition number used before the idle state; the base station optimizes the initial MPDCCH repetition number, and uses the optimized MPDCCH repetition number as the corresponding MPDCCH repetition number of the user equipment; wherein the optimized The number of repetitions of the MPDCCH is smaller than the initial number of repetitions of the MPDCCH.

[0060] Since the embodiment of the present invention obtains the initial MPDCCH repetition number used by the user equipment, the initial MPDCCH repetition number is optimized, and the optimized MPDCCH repetition number is smaller than the initial MPDCCH repetition number. After recei...

Abstract

The embodiment of the invention relates to the technical field of wireless communication and particularly relates to a method and base station for determining machine type communication physical downlink control channel repetition times. The problem that in the prior art, employed MPDCCH (Machine Type Communication Physical Downlink Control Channel) repetition times is excessive and system resources are wasted when the base station sends paging messages through utilization of the MPDCCH repetition times sent by a core network is solved. According to the embodiment of the invention, the base station obtains initial MPDCCH repetition times employed by user equipment; the initial MPDCCH repetition times is optimized; the optimized MPDCCH repetition times is taken as the MPDCCH repetition times corresponding to the user equipment; and the optimized MPDCCH repetition times is smaller than the initial MPDCCH repetition times. when the base station sends the paging messages, the optimized relatively low MPDCCH repetition times is employed, so the system resources are saved.

Description

technical field [0001] The invention relates to the technical field of wireless communication, in particular to a method and a base station for determining the repetition times of a machine type communication downlink control channel MPDCCH. Background technique [0002] In order to make the Internet of Things user equipment working in the LTE (Long Term Evolution, long-term evolution) network system have greater coverage and lower acquisition costs, the 3GPP (3rd Generation Partnership Project, 3rd Generation Partnership Project) standard The organization proposed eMTC (enhanced Machine Type Communication, enhanced machine type communication) user equipment technology. Compared with other LTE user equipment, eMTC user equipment uses downlink single-antenna transmission and reception, which will suffer losses in terms of diversity gain and uplink transmission power, and the coverage area is relatively small. The eMTC user equipment at the cell edge of the LTE network is lim...
