Problems solved by technology

[0004] Then, for example, if there is a terminal device located at the edge of cell 1, in the area close to cell 2, the reception quality of the terminal device in cell 1 may not be good, and the terminal device is close to cell 2, and the interference brought by cell 2 is relatively large. Larger, it will lead to poor reception quality of the terminal equipment
[0005] It can be seen that the current SC-PTM technology may lead to poor reception quality of terminal equipment at the edge of the cell

Embodiment Construction

[0321] In order to make the purpose, technical solutions, and advantages of the embodiments of the present application clearer, the embodiments of the present application will be further described in detail below in conjunction with the accompanying drawings.

[0322] In the following, some terms used in the embodiments of the present application are explained, so as to facilitate the understanding of those skilled in the art.

[0323] 1) Terminal equipment, including equipment that provides voice and / or data connectivity to users, for example, may include a handheld device with a wireless connection function, or a processing device connected to a wireless modem. The terminal device may communicate with the core network via a radio access network (radio access network, RAN), and exchange voice and / or data with the RAN. The terminal equipment may include user equipment (user equipment, UE), wireless terminal equipment, mobile terminal equipment, device-to-device communication (...

Abstract

The invention relates to a communication method and device. The communication method comprises the steps that a first network device determines a first parameter for a first multicast service; and thefirst network device sends the first parameter to network devices corresponding to at least two cells, the at least two cells being associated with the first multicast service, and the first parameter indicating a resource for transmitting the first multicast service. Because the same parameters are used for the same service, terminal equipment located at the edge of the cell is not limited to only receive the multicast service of the cell, but also can receive the same multicast service sent by other cells, and the receiving success rate of the terminal equipment can be improved. The same multicast service sent by other cells is not an interference signal for the terminal equipment any more, so that the receiving quality of the terminal equipment is improved.

Description

technical field [0001] The present application relates to the technical field of communication, and in particular to a communication method and device. Background technique [0002] Single cell point to multipoint (single cell point to multipoint, SC-PTM) is a multicast transmission technology. In SC-PTM technology, in an area, only the cells that contain users need to send data to users, and the cells that do not contain users do not need to send data, thus saving air interface resources. [0003] Currently in SC-PTM technology, there is no connection between the transmissions of two cells. For example, cell 1 and cell 2 are two adjacent cells, both of which are performing SC-PTM transmission. There are terminal devices receiving the first service in cell 1, and terminal devices receiving the first service are also in cell 2. However, the terminal equipment in the cell 1 will not receive the first service sent by the cell 2, and the terminal equipment in the cell 2 will ...
