Embodiment 1

[0042] Step 100: the base station sends the transport block to the user equipment, so that the user equipment obtains the feedback information to be sent in the preset protocol according to the reception of the transport block, and at least one physical uplink control channel PUCCH required for sending the feedback information The identification; the preset protocol includes the correspondence between the combination of the feedback information and the identification of the PUCCH used and the reception situation of the transport block;

[0043] The base station can send one or more transmission blocks to the user equipment at the same time, and can also send transmission blocks to the user equipment in time-sharing. In order to ensure that the user equipment can completely receive the transmission blocks sent by the base station, the user equipment needs to check its own reception of the transmission blocks. Feedback to the base station. In order to improve the feedback efficie...

Embodiment 2

[0079] Such as figure 2 Shown is a structural block diagram of a resource allocation device according to an embodiment of the present invention. It can be seen from the figure that the resource allocation device includes:

[0080] The sending module 21 is configured to send the transmission block to the user equipment, so that the user equipment obtains the feedback information to be sent in the preset protocol according to the reception of the transmission block, and at least one physical uplink control required for sending the feedback information The identification of the channel PUCCH; the preset protocol includes the correspondence between the combination of the feedback information and the identification of the PUCCH used and the reception situation of the transport block;

[0081] The first obtaining module 22 is configured to, before the sending module 21 sends at least one transmission block to any user equipment, according to the transmission block that the user equ...

Abstract

The invention relates to a resource allocation method. The resource allocation method comprises the following step that: a base station inquires a preset protocol according to the number of downlink transport blocks of the base station to allocate PUCCH (Physical Uplink Control Channel) resources to user equipment, so that the user equipment acquires feedback information to be transmitted from the preset protocol according to a reception condition of the transport blocks, and an identifier of at least one PUCCH needing to be used to transmit the feedback information. In the resource allocation scheme, the base station determines the PUCCH resources actually needed by the user equipment to transmit a feedback signal according to an actual scheduling transmission quantity of the base station, and performs resource allocation according to the PUCCH resources actually needed by the user equipment, so that unnecessary PUCCH resource allocation is reduced, and the utilization rate of the PUCCH resources is increased.

Description

technical field [0001] The present invention relates to the field of communication technologies, in particular to a resource allocation method and device. Background technique [0002] The Long Term Evolution-Advanced (LTE-A) is an evolved version of the Long Term Evolution (LTE). Compared with LTE, in the LTE-A protocol, for the Physical Uplink Control Channel (Physical UplinkControl Among the new mechanisms of CHannel, PUCCH), one of them is that the new carrier aggregation function introduces the PUCCH1B CS (PUCCH Format1B with Channel Selection, PUCCH Format 1B channel selection) format, which is used to transmit the feedback response signal to the downlink, that is to say After the base station sends a data block to the user equipment, the user equipment feeds back a response signal of reception status to the base station through this format, which requires the base station to allocate PUCCH resources for the user equipment to enable the user equipment to send a feedbac...
