Embodiment Construction

[0025] In order to solve the problems of large occupied information carrying space and large processing resources consumed in the determination method of carrier aggregation bandwidth in the prior art, an embodiment of the present invention provides a solution for reporting the capability of a terminal to support carrier aggregation bandwidth. In this solution, the terminal carries the carrier aggregation bandwidth capability identification of the terminal in the specified bits contained in the Feature Group Indicators (FGI, Feature Group Indicators) bits of the UE Capability message, so that the carrier aggregation bandwidth capability identification of the terminal only occupies a small amount of information bearer Space; at the same time, the above-mentioned terminal supports carrier aggregation bandwidth capability identifiers can correspond to multiple carrier aggregation bandwidths (carrier aggregation bandwidth sets) at the same time, and the terminal does not need to det...

Abstract

The invention discloses a method for reporting a terminal's ability to support carrier aggregation bandwidth to solve the problems of larger space occupation and more processing resources consumed in the existing ability information reporting method. The method includes: the network side receives the terminal capability message sent by the terminal; from the specified bits contained in the FGI bit in the terminal capability message, obtains the terminal support carrier aggregation bandwidth capability identifier; according to the pre-agreed terminal support carrier aggregation bandwidth capability identifier and the terminal The corresponding relationship of the supported carrier aggregation bandwidth sets determines the carrier aggregation bandwidth set corresponding to the acquired carrier aggregation bandwidth capability identifier of the terminal. The invention also discloses a system, network side equipment and terminal.

Description

technical field [0001] The present invention relates to the field of communication technologies, and in particular to a method, a system, a network side device and a terminal for reporting a carrier aggregation bandwidth capability of a terminal. Background technique [0002] At present, each carrier supported by the LTE-Advanced system adopts the basic bandwidth configuration of LTE, and the configuration supports 6 bandwidths of 1.4MHz, 3MHz, 5MHz, 10MHz, 15MHz, and 20MHz. Based on these 6 bandwidths, in the case of two carrier aggregations, there may be a total of 36 carrier aggregation bandwidth configuration modes, as shown in Table 1. [0003] Table 1: [0004] Carrier aggregation bandwidth (MHz) 20+20 20+15 20+10 ... 15+15 15+10 ... 1.4+1.4 [0005] For the terminal, due to software limitations, it cannot support various carrier aggregation bandwidths that may be generated by two carrier aggregations. This may cause some proble...
