Abstract

The present invention discloses a method and a device for processing a physical downlink channel. The method comprises the steps of: determining an RE (Resource Element) occupied by a CSI-RS (Channel State Information-Reference Signal); and performing rate matching and physical resource mapping for a physical downlink channel according to the determined RE occupied by the CSI-RS. The method and the device of the invention can solve the problem that the RE used by the physical downlink channel conflicts with the RE occupied by the CSI-RS.

Description

technical field [0001] The present invention relates to the technical field of communications, in particular to a method and device for processing a physical downlink channel. Background technique [0002] In an LTE (Long Term Evolution, long term evolution) system, a PDCCH (Physical Downlink Control Channel, Physical Downlink Control Channel) carries scheduling information and other control information. PDCCH is sent in the first N OFDM (Orthogonal Frequency Division Multiplexing, Orthogonal Frequency Division Multiplexing) symbols of a downlink subframe, and the possible values ​​of N are 1, 2, 3, 4, where N=4 is only allowed to appear when the system bandwidth is 1.4 MHz system. The number of symbols of the PDCCH (that is, the number of symbols in the control region) is indicated by a PCFICH (PhysicalControlFormatIndicatorChannel, Physical Control Format Indicator Channel). The PDCCH is distributed over the entire system bandwidth in the frequency domain, thereby obtain...
