Problems solved by technology

[0011] In the process of realizing the present invention, the inventor found through research that the following problems exist in the prior art: when the uplink system bandwidth transmits both user data and uplink control signaling, the bandwidth not used by any user's uplink control signaling must be The RB resources reserved for PUCCH are allocated to user data. The resource allocation indication of the existing physical layer uplink scheduling authorization command can only reach the VRB unit, so there will be some problems when using it. The following will illustrate it more clearly w

Example Embodiment

[0133]Example one:

[0134] In the 3GPP E-UTRA system, there are usually no more than 8 uplink control signaling units reserved for PUCCH. In most cases, x (the difference between the start resource block addresses allocated to user data and the end The value of the difference between the resource block addresses) will not exceed the range of [-3, 3], that is, there are 7 values, so 3 bits of the PUCCH RB allocation field are sufficient. As a compromise between overhead and performance, it is also possible to limit the value of x not to exceed the range of [-1, 1]. In this case, 2 bits of the PUCCH RB allocation field are sufficient.

[0135] In the example, suppose that the PUCCH RB field is 3 bits, and the corresponding relationship between the value of these 3 bits and the value of x is shown in Table 1 below

[0136] PUCCH RB allocation field value 000 001 010 011 100 101 110 111 x value 0 1 -1 2 -2 3 -3 Reserved

Example Embodiment

[0165] Embodiment two:

[0166] It is assumed that user data can only occupy the RB resources reserved for PUCCH in the following three modes. Mode 1: For all VRBs that contain PUCCH upper sideband reserved RB resources allocated to user data, user equipment can only use the RB resources corresponding to the VRB in the first half subframe; for all PUCCH lower sidebands allocated to user data, reserve RB resources Resource VRB, the user equipment can only use the RB resources corresponding to the VRB in the second half subframe. Mode 2: For all VRBs that contain PUCCH upper sideband reserved RB resources allocated to user data, user equipment can only use the RB resources corresponding to the VRB in the second half subframe; for all PUCCH lower sidebands allocated to user data, reserved For the VRB of the RB resource, the user equipment can only use the RB resource corresponding to the VRB in the first half subframe. Mode 3: For all VRBs containing PUCCH upper sideband or lower sideb...

Abstract

The invention discloses a method, a device and a system for sending and receiving information for scheduling user data, relates to the field of wireless communication and aims to solve the problem of impossibility in confirming which particular part of time domain and frequency domain resources in PUCCH resource reservation is available to the user data in the prior art. The he method provided by the embodiment of the invention comprises the following steps: a field for controlling the distribution of channel resource block on the up link of a physical layer is included in an authorized command for scheduling the uplink of a physical layer. When at least one part of virtual resource block distributed to the user equipment in the uplink system bandwidth is the resource block reserved by the control channel in the uplink of the physical layer, the resource block distributing field of the control channel in the uplink of the physical layer carries resource block location information of the user data distributed to the user equipment in the uplink system bandwidth. The invention is suitable for solving data distributing problem in wireless communication.

Description

technical field [0001] The invention relates to the field of wireless communication, in particular to a method, device and system for sending and receiving scheduling user data information in wireless communication. Background technique [0002] The 3rd Generation Partnership Project (3GPP, 3rd Generation Partnership Project) Evolved Universal Terrestrial Radio Access (E-UTRA, Evolved Universal Terrestrial Radio Access) system includes a user equipment and a base station, and the uplink system bandwidth between the user equipment and the base station uses a single carrier ( Single Carrier) frequency division multiple access technology transmits information, and the information includes: uplink control signaling and user data. [0003] The entire uplink system bandwidth can be used to transmit user data; when it is necessary to transmit uplink control signaling, use the resources reserved for the Physical Uplink Control Channel (PUCCH) on the upper and lower sidebands of the ...
