Problems solved by technology

However, the search space of the 5G unlicensed communication system is related to the position where the channel idle detection is successful, so the position of the search space is flexible, and the configuration and reception method with a fixed time position on the licensed frequency band is no longer applicable to the licensed frequency band

Embodiment Construction

[0030] In order to make the technical problems, technical solutions and advantages to be solved by the embodiments of the present invention clearer, the following will describe in detail with reference to the drawings and specific embodiments.

[0031] In New Radio (NR) Rel15, the configuration information of the search space of the system information is sent in a Synchronization Signal Block (Secondary Synchronization Signal, SSB) and / or a Physical Broadcast Channel (Physical Broadcast Channel, PBCH). For frequency bands below 6 GHz, SSB / PBCH and Type 0 (Type0) Physical Downlink Control Channel (PDCCH) resources use multiplexing mode 1, that is, SSB / PBCH and Type 0 PDCCH cannot overlap in the time domain. In this mode, the user can 0 A slot monitors the Type0 PDCCH, where n 0 The following conditions are satisfied: For SSB index i, if It is at an even frame number, if It is at odd frame numbers. The values ​​of M and O are given in Table 1:

[0032] Table 1 Type0 PDC...

Abstract

The invention provides a search space configuration method and device and a communication equipment and belongs to the technical field of wireless communication. The search space configuration methodis applied to user equipment, and comprises the following steps: detecting at least one synchronization signal block; acquiring configuration information of a search space corresponding to the detected synchronization signal block, wherein the configuration information comprises QCL mode information and / or cell detection signal transmission window information; and determining the position of the search space of the PDCCH according to the detected time synchronization information of the synchronization signal block and the configuration information. According to the technical scheme provided bythe invention, the purpose of flexibly configuring the search space of the UE can be achieved so as to ensure that the UE can timely and effectively receive various types of downlink control information.

Description

technical field [0001] The present invention relates to the technical field of wireless communication, in particular to a search space configuration method and device, and communication equipment. Background technique [0002] For 5G, in the standard discussion of New Radio Access Technology (NR), user equipment (User Equipment, UE) needs to monitor various types of downlink control information (Downlink Control Information, DCI). Wherein, the UE may detect a physical downlink control channel (Physical Downlink Control Channel, PDCCH) sent by a network side device in a search space of the UE in a blind detection manner to obtain the DCI. [0003] The search space of the 5G licensed communication system is on a fixed time slot (slot). However, the search space of the 5G unlicensed communication system is related to the position where the channel idle detection is successful, so the position of the search space is flexible, and the configuration and reception method with a fi...
