Embodiment 1

[0050] According to an embodiment of the present invention, a method for representing a physical resource is provided, which is used for representing the location of the physical resource of semi-static data. Figure 5 It is a flow chart of the representation method of physical resources according to Embodiment 1 of the method of the present invention, such as Figure 5 shown, including the following processing:

[0051] Step S502, using length-limited continuous virtual resource blocks to represent physical resource locations of semi-persistent scheduling data.

[0052] In step S502, the specific process of using the length-limited continuous virtual resource blocks to represent the physical resource positions of the semi-persistent scheduling data is: the number L of length-limited continuous virtual resource blocks allocated to the semi-persistent scheduling data CRBs and the starting position RB of continuous virtual resource blocks allocated to semi-persistently schedule...

example 1

[0057] In Example 1, the physical resource position of the uplink semi-persistent scheduling data is represented by a length-limited continuous virtual resource block representation method.

[0058] The physical resource position of uplink semi-persistent scheduling data is determined by the number of virtual resource blocks L allocated to uplink semi-persistent scheduling data CRBs and the starting position RB of the virtual resource block allocated to the uplink semi-persistent scheduling data START OK, yes L CRBs and RB START Code as follows, RIV means L CRBs and RB START The encoded result is the resource representation signaling of the uplink semi-persistent scheduling data;

[0059] L CRBs and RB START The encoding method is: when , RIV=N RB (L CRBs -1)+RB START ; Otherwise, RIV=N RB (N RB -L CRBs +1)+(N RB -1-RB START ).

[0060] In addition, the maximum number of continuous virtual resource blocks of uplink semi-persistently scheduled data physical resou...

example 2

[0062] In Example 2, the physical resource position of the downlink semi-persistent scheduling data is represented by a length-limited continuous virtual resource block representation method.

[0063] The physical resource position of the downlink semi-persistent scheduling data is determined by the number of virtual resource blocks L allocated to the downlink semi-persistent scheduling data CRBs and the starting position RB of the virtual resource block allocated to the downlink semi-persistent scheduling data START OK, yes L CRBs and RB START Code as follows, RIV means L CRBs and RB START The encoded result is the resource representation signaling of the downlink semi-persistent scheduling data;

[0064] Among them, L CRBs and RB START The specific encoding method is: when , RIV=N RB (L CRBs -1)+RB START ; Otherwise, RIV=N RB (N RB -L CRBs +1)+(N RB -1-RB START ).

[0065] The maximum number of continuous virtual resource blocks of downlink semi-persistently...

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...
