Embodiment Construction

[0160] In order to make the object, technical solutions, and advantages of the present application, the present application will be further described in detail below with reference to the accompanying drawings.

[0161] Hereinafter, some terms in the present application embodiments are explained to facilitate the understanding of those skilled in the art.

[0162]1) Terminal, also known as terminal equipment, user equipment, MOBILESTATION, MS), mobile terminal (Mobile Terminal, MT), etc., is a voice and / or data communication to the user. Sexual equipment, such as a hand-held device having a wireless connection function, or a processing device connected to a wireless modem. The terminal can communicate with the core network via a radio access network (RAN), and the voice and / or data are exchanged with the RAN. The terminal may include a user equipment (UE), a wireless terminal, a mobile terminal, a subscriber unit, a subscriber station, a mobile station (Mobile), Mobile station...

Abstract

A communication method and device for reducing the complexity of a terminal when performing phase compensation. In this method, the network device first generates first information, and indicates to at least one terminal in the positioning system the information of the cell group in which each of the at least two cells in the positioning system is located through the first information, and then sends the The first information is sent to each terminal. After the terminal receives the first information, if the terminal wants to perform positioning measurement, it can be determined according to the first information that the reference signal sent by the cell in the cell group indicated by the first information arrives at the symbol boundary of the terminal. of. Since the symbol boundaries of the multiple reference signals of the multiple cells received by the terminal are synchronized, the terminal can perform phase compensation only once for the one cell group, thereby reducing the number of times the terminal performs phase compensation and reducing the number of times the terminal performs phase compensation. Complexity when performing phase compensation.

Description

Technical field [0001] The present application relates to the field of communication technologies, and more particularly to a communication method and apparatus. Background technique [0002] In the LTE (long term evolution, LTE) system proposed time difference (observed time differenceof arrival, OTDOA) observed positioning reference signal (positioning reference signal, PRS) is based on the arrival positioning scheme, the basic principle is: the base station configures a plurality of PRS is transmitted together to the terminal cell, the terminal selects a cell as auxiliary information from reference cell in the plurality of cells, other neighboring cells as auxiliary information, after the terminal receives the transmitted PRS each cell, each of the auxiliary information is calculated o PRS region with respect to a reference signal time PRS auxiliary information of the reference cell difference (reference signal time difference, RSTD), and to the enhanced service mobile locatio...
