Embodiment Construction

[0019] figure 1 It is a flowchart of an embodiment of a method for implementing carrier aggregation on a backhaul link provided by the present invention. Such as figure 1 As shown, the execution subject of the following steps may be a relay node in the LTE-A network, and the method for implementing carrier aggregation on the backhaul link specifically includes:

[0020] S101. The relay node receives uplink data sent by the user equipment;

[0021] The relay node set in the LTE-A network can receive uplink data sent by user equipment such as mobile phones, Pads, portable laptops, etc. through the carrier on the access link.

[0022] S102, the relay node determines whether carrier aggregation is performed on the backhaul link between the relay node and the macro base station according to the transmission rate of the data actually carried on the main carrier and the transmission rate required by the uplink data;

[0023] Wherein, the primary carrier is an original carrier used...

Abstract

The invention provides a method for realizing carrier aggregation on a backhaul link and a relay node. The method comprises the steps that the relay node receives uplink data transmitted by user equipment; the relay node judges whether to perform carrier aggregation to the backhaul link between the relay node and a macro base station or not according to transmission rate actually carried data on main carriers and the transmission rate required by the uplink data; if a judgment of performing carrier aggregation to the backhaul link is made, after auxiliary carriers required for carrier aggregation of the backhaul link are determined, the relay node transmits the uplink data to the macro base station through the auxiliary carriers on the backhaul link and the main carriers. The method for realizing carrier aggregation on the backhaul link and the relay node provided by the embodiment of the invention effectively solve the problem that the data transmission efficiency is influenced because whether the carrier aggregation is performed to an uplink or not cannot be judged in the prior art.

Description

technical field [0001] The present invention relates to the field of communication technologies, and in particular to a method for realizing carrier aggregation on a backhaul link and a relay node. Background technique [0002] The Long Term Evolution Advanced (LTE-A) system proposes a carrier aggregation (Carrier aggregation, CA) technology, which aims to provide a larger bandwidth for a user equipment (User Equipment, UE) with corresponding capabilities, so as to increase the peak rate of the UE. In the LTE system, the maximum downlink transmission bandwidth supported by the system is 20MHz, and carrier aggregation is to aggregate two or more component carriers (ComponentCarriers, CC) to support a downlink transmission bandwidth greater than 20MHz, and the maximum does not exceed 100MHz. [0003] LTE-A also proposes a multi-level hybrid network (Heterogeneous Network, HetNet) network structure. In the R10 version of LTE-A, the relay (relay) technology is introduced to impr...
