Embodiment Construction

[0037] The following will clearly and completely describe the technical solution of the present invention in conjunction with the accompanying drawings of the present invention. Obviously, the described embodiments are only some of the embodiments of the present invention, not all of them. 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.

[0038] In a multi-carrier system, in order to increase the peak rate, the UE can work on multiple component carriers. The multi-carrier system will configure a set of working carriers for the UE according to the sum of the average rate of the service requested by the UE, and because the service of the UE may have Fluctuation and suddenness, when the UE traffic is relatively small, in order to better save power, the carrier in the working carrier set configured for the UE can be furth...

Abstract

The embodiment of the invention discloses a method for determining a search space of a physical downlink control channel component carrier (PDCCH CC), which comprises that: user equipment acquires the activation state of a physical downlink shared channel component carrier (PDSCH CC), and determines the search space of the PDCCH CC according to the activation state of the PDSCH CC. In the embodiment of the invention, the method for determining the search space of the PDCCH CC according to the activation state of the PDSCH CC can regulate the search space in time so as to save power more effectively at the same time of reducing unnecessary PDCCH blind detection.

Description

technical field [0001] The present invention relates to the field of communication technology, in particular to a method and equipment for determining a PDCCH CC search space. Background technique [0002] LTE (Long Term Evolution, long-term evolution) is the evolution of 3G (3rd Generation, third-generation digital communication), LTE improves and enhances 3G air access technology, adopts OFDM (Orthogonal Frequency Division Multiplexing, Orthogonal Frequency Division Multiplexing) ) and MIMO (Multiple Input Multiple Output, Multiple Input Multiple Output) as standards for the evolution of the LTE wireless network. Among them, in the LTE system and the previous wireless communication system, there is only one carrier in a cell, such as figure 1 As shown, the maximum bandwidth in the LTE system is 20MHz; and under the spectrum bandwidth of 20MHz, LTE can provide a peak rate of downlink 100Mbit / s and uplink 50Mbit / s, improve the performance of cell edge users, increase cell c...
