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

Abstract

The invention relates to a search space parameter configuration and adjustment method and device. The method includes: whether the current state meets the preset condition is determined; if the current state meets the preset condition, a search space configuration parameter corresponding to the current state is acquired from the plurality of sets of search space configuration parameters stored inadvance; the search space configuration parameter of the currently monitored search space is switched to the search space configuration parameter corresponding to the current state; the search space is continuously monitored using search space configuration parameters corresponding to the current state. In the technical solution, the search space configuration parameters that need to be switched are obtained and switched according to the current state, delay caused by the adjustment of the search space configuration parameters by the high-level signaling sent by the base station is avoided, ascheme for adjusting the search space configuration parameters at the optimal timing is implemented, the efficiency of the terminal adjusting the search space configuration parameter is improved, andpower consumption of the terminal is reduced.

Description

technical field [0001] 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 [0002] 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. [0003] 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 operation that consumes a lot of power in the terminal. In related technologies, in order to reduce the power consumption of the terminal, the base station can adjust the search space configuration parameters when the terminal monitors the PDCCH according to the service of the te...
