Embodiment Construction

[0044] The following will clearly and completely describe the technical solutions in the embodiments of the present invention with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only some, not all, embodiments of the present invention. Based on the embodiments of the present invention, all other embodiments obtained by persons of ordinary skill in the art without making creative efforts belong to the protection scope of the present invention.

[0045] In order to facilitate the understanding of the embodiments of the present invention, two different existing PDCCH design frameworks are firstly introduced. Figure 2a It is a schematic diagram of a DCI information processing process based on an existing PDCCH framework. The PDCCH is called a Type 1 PDCCH, and its information only includes DCI content. check code), convolutional coding, rate matching, interleaving, and mapping to PDCCH resources for tra...

Abstract

The embodiment of the invention discloses a configuration method of a physical downlink control channel (PDCCH), network equipment and a terminal, belonging to the technical filed of communication. The method comprises the following steps of: determining whether a carrier convergence mode is adopted for the terminal; and when the carrier convergence mode is adopted for the terminal, configuring the PDCCH types of all or a part of constitution carriers of the terminal into a second type, wherein in the second type, downlink control information (DCI) comprises a DCI type. Due to the adoption of the technical scheme, the blind test frequency of the terminal can be reduced.

Description

technical field [0001] The present invention relates to the field of communication technology, in particular to a method for configuring a physical downlink control channel, network equipment and a terminal. Background technique [0002] In the downlink service data transmission of the LTE (Long Term Evolution, Long Term Evolution) system, multiple MSs (Mobile Stations, mobile terminals) in a cell can dynamically multiplex time-frequency resources, and which time-frequency resources a certain MS occupies is determined by the The PDCCH (Physical Downlink Control Channel, Physical Downlink Control Channel) corresponding to the MS is used to indicate. The PDCCH of the MS can be located in the first 1 to 3 OFDM (Orthogonal Frequency Division Multiplexing, Orthogonal Frequency Division Multiplexing) symbols (Symbol) of a subframe (including 14 OFDM symbols in total, with a duration of 1ms), which is used to indicate the current PDSCH (Physical Downlink Shared Channel, physical d...
