Title
(EN) Communication method and communication device
(ZH) 通信方法和通信装置
Abstract
(EN) The invention provides a communication method and a communication device. The communication method comprises the following steps: communication is carried out, the terminal equipment receives the first indication information and the second indication information from the network equipment, wherein the first indication information is used for indicating the position of a first reference point, thesecond indication information is used for indicating a first number, the first number is the number of offset units included between the first reference point and a second reference point, and the second reference point is an end point of a first physical resource block PRB; And the terminal equipment determines the position of the first PRB according to the first indication information, the second indication information and the identifier of the subcarrier corresponding to the first reference point, so that the terminal equipment can complete the determination process of the PRB correspondingto the PRB number starting point in the system bandwidth under the condition that the system bandwidth is not known.
(ZH) 本申请提供了一种通信方法和通信装置,该通信方法包括:终端设备从网络设备接收第一指示信息和第二指示信息,该第一指示信息用于指示第一参考点的位置,该第二指示信息用于指示第一数量,该第一数量是该第一参考点与第二参考点之间包括的偏移单位的数量,该第二参考点是第一物理资源块PRB的端点;该终端设备根据该第一指示信息、第二指示信息和该第一参考点对应的子载波的标识,确定该第一PRB的位置,从而,能够使终端设备在不获知系统带宽的情况下,完成对系统带宽中PRB编号起点对应的PRB的确定过程。
