Embodiment Construction

[0038]In the following detailed description of the preferred embodiment, reference is made to the accompanying drawings which form a part hereof. The accompanying drawings show, by way of example, specific embodiments in which the invention can be practiced. The illustrated embodiments are not intended to be exhaustive of all embodiments in accordance with the invention. It is to be understood that other embodiments may be utilized and structural or logical changes may be made without departing from the scope of the present invention. Accordingly, the following detailed description is not limiting, and the scope of the invention is defined by the appended claims.

[0039] First, according to the application scenario of the present invention, there is an area covered by an LTE communication system, including at least one base station, namely eNB1, and a UE, namely UE1, and an authorized carrier connecting the two, that is, the primary cell (Pcell for short). ). In addition, ...

Abstract

Provided is a method for allocating secondary cell uplink resources to user equipment in a base station of an LTE communication system. A secondary cell is an unauthorized carrier. The method comprises the steps that the base station determines a first number P, wherein the first number P is the minimum number of uplink physical resource blocks which are allocated to the user equipment through the base station; the base station determines a second number L and partitions all the uplink physical resource blocks of the secondary cell into L collections, wherein each collection comprises P physical resource blocks; the base station allocates at least one collection in the L collections to the user equipment.

Description

technical field [0001] The present invention relates to the technical field of communication, in particular to the technical field of wireless communication. Background technique [0002] In the field of wireless communication, generally speaking, the traditional deployment method is that the system works in a licensed frequency band (licensed band), that is, the entire spectrum resource is reserved for the system to use. Typically, the LTE communication system works using licensed frequency bands. [0003] However, with the further growth of wireless services, the requirements for the capacity and frequency band of the wireless communication system are also increased. In this case, the licensed frequency band resources of the LTE system appear to be relatively insufficient. Therefore, one of the recent research hotspots in the LTE field is how to use unlicensed frequency band resources to offload high-incidence data services. This kind of scheme is called LTE (LTE in Unl...
