Abstract

The invention provides a sending method and a receiving method of multicast service information, a base station and a terminal, and relates to the field of communication. The sending method of the multicast service information comprises the steps of writing transmission control information of a multicast control channel of a multicast service into system information; and sending the system information to the terminal, thus allowing the terminal to receiving information on the multicast control channel according to the transmission control information. The transmission control information of the multicast control channel is sent in the system information, so that repeated transmission of the transmission control information in a PDCCH is avoided, in this way, signaling overheads of a physical layer is saved, and PDSCH receiving delays are reduced.

Description

technical field [0001] The invention relates to the field of communication technology, in particular to a method for sending and receiving multicast service information, a base station and a terminal. Background technique [0002] The Narrow Band Internet of Things (NB-IoT) work phase (Work Item, WI) was passed and started in the 3GPP Release 13 (Release 13, R13) stage. The goal of the NB-IoT working stage is to standardize the wireless access of the Cellular Internet of Things (CIoT), and the technology is extended based on Long-Term Evolution (LTE) / Lateral Evolution of Long-Term Evolution (LTE-A), mainly The network characteristics / objectives considered are: enhanced indoor coverage, support for a large number of low-speed device access, low latency sensitivity, reduced device cost, reduced device power consumption, optimized network architecture, etc. [0003] An actual NB-IoT terminal can have low mobility, data transmission with the network side does not require high r...
