Method and device used in user equipment and base station for dynamic scheduling

Technical Field

The present application relates to a transmission method and apparatus in a wireless communication system, and more particularly, to a transmission scheme and apparatus for dynamic scheduling signaling.

Background

In the future, the application scenes of the wireless communication system are more and more diversified, and different application scenes put different performance requirements on the system. In order to meet different performance requirements of various application scenarios, research on New air interface technology (NR, New Radio) (or 5G) is decided on 3GPP (3rd Generation Partner Project) RAN (Radio Access Network) #72 global meetings.

In order to adapt to various application scenarios and meet access requirements of different User Equipments (UEs), a consensus is reached in 3GPP RAN1#86bis conference, that is, the UE may receive control information with a smaller received radio frequency bandwidth and then receive subsequent data transmission with a larger bandwidth, so that power consumption of the UE may be effectively reduced. On the other hand, since the maximum radio frequency bandwidth supported by different user equipments may be different, it is also required to consider the requirement of different receiving bandwidths in channel design.

Disclosure of Invention

The distribution of multiple candidates in the search space for a given aggregation level directly affects the minimum radio frequency bandwidth required for blind detection by a ue.

The application provides a solution for the design of the search space of the downlink control channel in NR, in particular for the distributed design of candidates (candidates) in the search space. By adopting the solution of the present application, a plurality of alternative distributions of a given aggregation level can be configured according to the used bandwidth limit or requirement, thereby reducing power consumption when receiving downlink control information and meeting the requirements of different user equipment capabilities.
