METHOD, BASE STATION DEVICE, TERMINAL DEVICE, AND COMMUNICATION SYSTEM FOR CHANNEL RESOURCE ALLOCATION

摘要

Embodiments of the present invention provide a method, a base station device, a terminal device, and a communication system for channel resource allocation. The method comprises: sending a cell broadcast message to a terminal device, the cell broadcast message comprising description information of a first parameter configuration and description information of a second parameter configuration corresponding to common enhanced-dedicated channel resources, the first parameter configuration being directed to a first transmission time interval TTI, and the second parameter configuration being directed to a second TTI different from the first TTI; receiving indication information sent by the terminal device, the indication information indicating that the terminal device selects the first TTI or the second TTI as a selected TTI; and allocating a common enhanced-dedicated channel resource to the terminal device according to the indication information. In the embodiments of the present invention, multiple TTIs are configured in a cell, and parameter configuration information of the multiple TTIs is broadcast to a terminal device. In this way, the terminal device can select a suitable TTI from the multiple TTIs, and a network side allocates a channel resource according to the selected TTI, thereby improving the allocation efficiency and usage efficiency of the system resources.
