Embodiment Construction

[0082] In the embodiments of the present application, "at least one" means one or more, and "multiple" means two or more. "And / or" describes the association relationship of associated objects, indicating that there can be three types of relationships, for example, A and / or B, which can mean: A exists alone, A and B exist simultaneously, and B exists alone, where A, B can be singular or plural. The character " / " generally indicates that the contextual objects are an "or" relationship. "At least one (item) of the following" or similar expressions refer to any combination of these items, including any combination of single item(s) or plural item(s). For example, at least one item (unit) of a, b or c can represent: a, b, c, a and b, a and c, b and c, or a, b and c, wherein a, b, c Each of the can be itself an element, or a collection containing one or more elements.

Abstract

The invention relates to a communication method and device and relate to the technical field of communication. The method comprises the following steps that: first terminal equipment determines that the timing of sending a sidelink signal to second terminal equipment is uplink timing, and sends the sidelink signal to the second terminal equipment according to the uplink timing. The sidelink signalincludes sidelink control information and sidelink data. According to the technical scheme, the interference of the sidelink signal on the uplink signal is reduced, the communication performance is improved, the method is suitable for the scene that the sidelink control information and the sidelink data are subjected to frequency division multiplexing or the sidelink control information and the sidelink data are sent in the same time unit, and parallel sending of the sidelink signal and the uplink signal can be achieved.

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] At present, in long term evolution (LTE), the base station configures an uplink timing advance (uplink timing advance) for each terminal device in the cell, so that the uplink signals sent by different terminal devices in the same cell on the same time slot The time of arrival at the base station is aligned, thereby helping to avoid interference among multiple uplink signals within a cell (intra-cell). Wherein, uplink signals sent by different terminal devices are orthogonal. However, communication between terminal devices may also cause interference to these uplink signals. [0003] Therefore, how to reduce the interference of communication between terminal devices to uplink signals has important practical value for improving communication performance.
