Problems solved by technology

Although this scheduling mechanism gives great scheduling flexibility to the base station (Evolved Node Base-station, referred to as "eNB"), the disadvantage is that the UE needs to perform multiple blind detections, which increases the complexity of the blind detection of the UE and increases the Energy consumption and cost of UE

Abstract

The invention discloses a scheduling information transmission method, user equipment and a base station. The method includes: generating random numbers corresponding to the user equipment according to preset rules; and when presence of the random numbers in pre-configured scheduling intervals is confirmed, subjecting control channels of the user equipment, in specific search space, to blind detection so as to obtain scheduling information of the user equipment. The user equipment comprises a generation module and a detection module. The base station comprises a generation module and a first transmitting module. Before detection or transmission of the control channels, whether the detection or transmission conditions are satisfied is determined, format of the control channels is determined and the position of the control channels is determined. Therefore, the times of blind detection of the control channels by the user equipment can be effectively reduced, electric quantity of the user equipment is reduced, energy consumption is lowered and user experience is improved further.

Description

technical field [0001] The present invention relates to the communication field, in particular to a method, user equipment and base station for transmitting scheduling information in the communication field. Background technique [0002] In the Long Term Evolution (referred to as "LTE") system, the user equipment (User Equipment, referred to as "UE") in each transmission time interval (Transmission Time Interval, referred to as "TTI") detects the physical downlink A control channel (Physical Downlink Control Channel, referred to as "PDCCH") obtains part of the scheduling information in the data field within the TTI, or a scheduling grant corresponding to an uplink subframe. [0003] PDCCH is a physical downlink control channel, which is located in the control domain part of the time-frequency resource in a subframe, and occupies the first N orthogonal frequency division multiplexing (Orthogonal Frequency Division Multiplexing, referred to as "OFDM") in a subframe in the inst...
