Embodiment Construction

[0033] In the following description, many details are set forth for illustrative purposes. However, those of ordinary skill in the art will recognize that the embodiments of the present disclosure can be implemented without using these specific details. Therefore, the present disclosure is not intended to be limited to the illustrated embodiments, but will be given the widest scope consistent with the principles and features described herein.

[0034] It should be understood that the terms "first", "second", etc. are only used to distinguish one element from another element. In fact, the first element can also be called the second element and vice versa. In addition, it should be understood that "including" and "including" are only used to describe the existence of the stated feature, element, function or component, but it does not exclude the existence of one or more other features, elements, functions or components.

[0035] For ease of explanation, the embodiments of the prese...

Abstract

The invention provides a channel resource distribution controlling method in a wireless communication system. The method comprises that a scheduling message is sent to equipment via a down link control channel, and the scheduling message indicates a resource used to transmit down link data to the equipment; the down link data is transmitted to the equipment in the indicated resource; an up link control channel resource back fed for the down link data and received from the equipment is determined; the aggregation level (AL) of the down link control channel used to send at least a first subframe of a scheduling message is determined; and feedback is received from the equipment via the determined up link control channel resource. The invention also provides a channel resource distribution controlling device. According to embodiments of the invention, conflicts in up link control channel resources can be reduced, and the utilization efficiency of the up link control channel resources is improved.

Description

Technical field [0001] The embodiments of the present disclosure relate to wireless communication, and more specifically to resource allocation and conflict resolution of control channels in a wireless communication system. Background technique [0002] A machine type communication (MTC) device is a user equipment (UE) used by a machine for a specific purpose. In the Third Generation Partnership Project (3GPP), in order to reduce the complexity / cost of MTC, the concept of Low Complexity MTC (LC-MTC) has been proposed. A technology to reduce complexity is to reduce the radio frequency (RF, or radio frequency) bandwidth of the LC-MTC device to 1.4MHz, that is, make the device work in the LTE system bandwidth of 6 physical resource blocks (PRB) size In the narrow band. It has been agreed at the 3GPP Rel-13RAN1#82 meeting for LC-MTC equipment that the LC equipment only needs to support 1.4MHz radio frequency bandwidth in the uplink and downlink. [0003] On the other hand, consideri...
