Abstract

The invention provides an access method for a wireless communication system. The method includes: detecting a basic synchronization channel and a secondary synchronization channel to execute synchronization; detecting community public reference signaling on a physical broadcast channel; utilizing the detected community public reference signaling to demodulate data transmitted on the physical broadcast channel and obtaining a cyclic redundancy check mask off code; and monitoring public searching space of a physical downlink control channel. The invention further provides corresponding user equipment.

Description

technical field [0001] The present invention relates to the technical field of wireless communication, and more particularly, to a method and device for accessing a wireless communication system. Background technique [0002] In the 3rd Generation Partnership Project (3GPP) Long Term Evolution (LTE) Rel-8 / 9 / 10 system, the base station transmits Cell-specific Reference Signaling (CRS) in each downlink data subframe for It is used to support the demodulation of physical downlink shared / control channel data. At the same time, the user equipment also uses the cell common reference signaling CRS as a reference signaling for downlink channel measurement. [0003] In LTE Rel-10, in addition to using the cell common reference signaling CRS as the demodulation reference signaling, a user equipment-based demodulation reference signaling (Demodulation Reference Signal, Demodulation Reference Signal, DMRS). The use of the demodulation reference signaling DMRS based on the user equipm...
