Abstract

The embodiment of the invention provides a terminal capability reporting method, a terminal capability determining method, a terminal and a network side device. The terminal capability reporting method comprises the following steps: acquiring layer number information respectively supported by a plurality of carriers in downlink carrier aggregation supported by the terminal; generating carrier aggregation capability report information, when the carrier aggregation is continuous carrier aggregation, the carrier aggregation capability report information carrying continuous carrier aggregation indication information for indicating that the plurality of carriers are continuous carriers and layer number indication information for indicating layer number information supported by the plurality ofcarriers respectively; and sending the carrier aggregation capability report information to network side equipment. According to the embodiment of the invention, the continuous carrier aggregation indication information is introduced to indicate that a plurality of carriers in the downlink carrier aggregation supported by the terminal are continuous carriers, and the terminal capability can be accurately reported according to the condition of downlink continuous multi-carrier aggregation.

Description

technical field [0001] The present invention relates to the field of communication technologies, and in particular to a terminal capability reporting method, a determination method, a terminal and a network side device. Background technique [0002] With the introduction of downlink multi-stream capability, due to the limitation of terminal capabilities, under continuous carriers, only some carriers can support downlink multi-stream, while other carriers support 2-stream, and only partial sequential layer combination can be achieved. [0003] For example, for downlink continuous three-carrier aggregation, it can only support 4 streams for two consecutive carriers, and 2 streams for the other carrier, and does not support 4 streams for two non-contiguous carriers. In this case, if the report is made according to the existing method, two situations will occur: 1. The ability of the terminal to support 4 downlink streams under continuous downlink three-carrier aggregation canno...
