Abstract

The invention discloses expression methods and a device of a physical resource, wherein, one of the methods comprises the steps of utilizing continuous virtual resource blocks with limited length to express the physical resource position of semi-static dispatching data. By the technical proposal, the bit overhead of physical resource expression of semi-static dispatching data is reduced, and the saved bits are used for a virtual CRC, thus effectively improving the detection performance of physical downlink control channel.

Description

technical field

[0001] The present invention relates to the communication field, and in particular, to a method and device for representing physical resources. Background technique

[0002] The Long Term Evolution (LTE for short) system is an important plan of the third generation partnership organization. figure 1 A schematic diagram showing a basic frame structure in an LTE system, such as figure 1 As shown, the frame structure can be divided into four levels: radio frame, half frame, subframe, time slot and symbol, wherein, the length of a radio frame is 10ms, and a radio frame is composed of two half frames, and each half The length of the frame is 5ms, one half frame is composed of 5 subframes, the length of each subframe is 1ms, and one subframe is composed of two time slots, and the length of each time slot is 0.5ms.

[0003] When the LTE system adopts the conventional cyclic prefix, a time slot can contain 7 uplink / downlink symbols with a length of 66.7us, among wh...
