Problems solved by technology

However, the base station usually uses high-level signaling to configure new search space configuration parameters for the terminal, and the terminal processes the high-level signaling for a long time. Therefore, it takes For a long time, when the terminal finally adjusts the configuration parameters of the search space, the status of its business has changed, causing the terminal to miss the best adjustment opportunity, which in turn makes the terminal unable to effectively reduce the power consumption of the terminal

specific Embodiment 1

[0293] image 3 It is an interaction diagram showing a search space parameter configuration and adjustment method according to an exemplary embodiment, and the search space parameter configuration and adjustment method is applied to a terminal and a base station. Such as image 3 As shown, the following steps 301 to 313 are included:

[0294] In step 301, after configuring the search space for the terminal, the base station acquires multiple sets of search space configuration parameters and initial search space configuration parameters that need to be configured for the terminal according to the initial state of the terminal.

[0295] The search space configuration parameters include the search period, the number of time units that are continuously searched in each search period, the monitoring opportunity in the time unit, the degree of CCE aggregation in each monitoring opportunity, the potential transmission position of the PDCCH under each degree of CCE aggregation, and ...

[0313] Figure 4 It is an interaction diagram showing a search space parameter configuration and adjustment method according to an exemplary embodiment, and the search space parameter configuration and adjustment method is applied to a terminal and a base station. Such as Figure 4 As shown, the following steps 401 to 420 are included:

[0314] In step 401, after configuring the search space for the terminal, the base station acquires multiple sets of search space configuration parameters that need to be configured for the terminal according to the initial state of the terminal.

[0315] Each set of search space configuration parameters includes the search period for monitoring the search space, the number of time units for continuous search in each search period, the monitoring opportunity in this time unit, the degree of CCE aggregation in each monitoring opportunity, and the At least one of a potential transmission position of the PDCCH and a DCI format.

Abstract

The invention relates to a search space parameter configuration and adjustment method and device. The method comprises the steps of determining whether a current state meets a preset condition or not; if the current state meets the preset condition, acquiring a search space configuration parameter corresponding to the current state from a plurality of sets of pre-stored search space configuration parameters; switching a search space configuration parameter of a current monitoring search space to a search space configuration parameter corresponding to the current state; and continuously monitoring the search space by adopting the search space configuration parameter corresponding to the current state. In the technical scheme, the search space configuration parameters needing to be switched are obtained according to the current state and switched, so that time delay caused by adjustment of the search space configuration parameters through high-level signaling sent by the base station is avoided, the scheme that the terminal adjusts the search space configuration parameters at the best time is achieved, the efficiency of adjusting the search space configuration parameters by the terminal is improved, and the power consumption of the terminal is reduced.

Description

[0001] This application is a divisional application, the application number of the original application is: 201880001970.X, the application date is October 11, 2018, and the title of the invention is "search space parameter configuration and adjustment method and device". technical field [0002] The present invention relates to the field of communication technology, in particular to a search space parameter configuration and adjustment method and device. Background technique [0003] With the development of communication technology, there are more and more types of services that mobile communication can support, such as multimedia services, cloud services, and interactive services. In order to support these types of services, the power consumption of terminals is also increasing. [0004] By analyzing the power consumption of the terminal, it can be known that receiving and processing a PDCCH (Physical Downlink Control Channel, physical downlink control channel) is an operat...
