Method and base station for determining repetition times of downlink control channel of machine type communication

Abstract

An embodiment of the present application relates to the field of wireless communications, and particularly relates to a method and a base station for determining a number of MPDCCH repetitions, so as to solve the problem in the prior art in which when a base station transmits a paging message using a number of MPDCCH repetitions transmitted by a core network, the number of MPDCCH repetitions used in transmitting the paging message may be too large, resulting in wastage of resources. According to the embodiment of the present application, a base station obtains an initial number of MPDCCH repetitions used by user equipment; and performs an optimization process on the initial number of MPDCCH repetitions, and uses the optimized number of MPDCCH repetitions as a number of MPDCCH repetitions corresponding to the user equipment, wherein the optimized number of MPDCCH repetitions is less than the initial number of MPDCCH repetitions. In this way, a base station uses an optimized small number of MPDCCH repetitions when transmitting a paging message, thereby saving system resources.

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...
