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 with examples
[0014] From the above discussion, we can see that when the existing technology allocates resources reserved for PUCCH for user data through the physical layer uplink scheduling authorization command, it is impossible to further use the existing resource allocation indication method in units of VRB. Specify which part of the time domain and frequency domain resources reserved for PUCCH can be used by user data, which makes it possible for user data to use the RBs that have been allocated for uplink control signaling, which will affect user data and signaling normal transmission

Embodiment 1

[0134] In the 3GPP E-UTRA system, usually no more than 8 uplink control signaling units are reserved for PUCCH. The value of the difference between 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, the value of x can also be limited to not exceed the range of [-1, 1]. In this case, only 2 bits in the PUCCH RB allocation field are sufficient.

[0135] In the example, it is assumed 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

Embodiment 2

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

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 ...
