Embodiment Construction

[0034] In the prior art, the signaling and data transmitted by the base station are received by the user terminal in a unit of one subframe, that is, the signaling and data transmitted by the base station are received in the unit of 1 ms. Correspondingly, the base station schedules the UE also in units of 1 ms. In the prior art, the time delay for the base station to schedule the UE is relatively long.

[0035] In the embodiment of the present invention, when receiving the physical resource block of the second time slot issued by the base station, the corresponding downlink control signaling is detected therefrom, and according to the data transmission type corresponding to the downlink control signaling, at the corresponding time Downlink data reception or uplink data transmission is performed on the slot, so that the user terminal can be scheduled in one time slot, and the time delay for the base station to schedule the user terminal can be shortened.

[0036] In order to m...

Abstract

A user terminal scheduling method and device, the method comprising: receiving physical resource block configuration information issued by a base station, where the physical resource block is a physical resource block in the second time slot of a subframe; constructing the physical resource block into a physical A resource block pair; receiving a signal sent by the base station in the physical resource block, and detecting the corresponding downlink control signaling from the physical resource block pair; when the downlink control signaling indicates to perform downlink data reception, in the sub In the second time slot of the frame, downlink data is received on the resources indicated by the downlink control signaling; when the downlink control signaling indicates the execution of uplink data transmission, the Mth time slot after receiving the downlink control signaling time slot to send uplink data. By adopting the method and device, the time delay for the base station to schedule the UE can be effectively shortened.

Description

technical field [0001] The present invention relates to the field of wireless communication, and in particular, to a user terminal scheduling method and device. Background technique [0002] In the existing solution of the Long Term Evolution (Long Term Evolution, LTE) system, the process for a user terminal (User Equipment, UE) to receive signaling and data transmitted by a base station is as follows: First, receive the first to third symbols located in the subframe. A physical downlink control channel (Physical Downlink Control Channel, PDCCH) in the symbol, from which it detects its own downlink control signaling. After that, according to the modulation and coding format (Modulation and Coding Scheme, MCS), resource block (Resource Block, RB) resource allocation information indicated by the downlink control signaling, etc., in the physical downlink shared channel (Physical Downlink Shared Channel, PDSCH, PDSCH of the subframe) ) to receive its own data. When the recepti...
