Title: METHODS OF MAPPING AND DETECTING BROADCAST CHANNEL, BASE STATION, AND USER EQUIPMENT
Abstract:
Provided are a method of mapping a broadcast channel and utilized in a base station in a time division duplex (TDD) mode, a method of detecting a broadcast channel and utilized in user equipment in a TDD mode, base station, and user equipment. The method of mapping a broadcast channel comprises: dividing a first broadcast channel into at least one first part and one second part; and mapping, to a second subframe in a plurality of subframes having an uplink-downlink configuration in the TDD mode, the first part of the first broadcast channel, and mapping, to the seventh subframe in the plurality of subframes, the second part of the first broadcast channel, wherein the second subframe is a special subframe, and the seventh subframe is a special subframe or a downlink subframe. The method is employed to follow a signal sequence design of a broadcast channel in a NB-IoT system in a FDD mode, and map, using a special subframe, the broadcast channel, without changing an uplink-downlink configuration of a NB-IoT system in the TDD mode.
