Problems solved by technology

However, when a large number of small cell cells need to be densely deployed, whether it is a centralized cell ID allocation method or a distributed cell ID allocation method, to meet the requirement that adjacent cells use different cell IDs, the network planning will be complicated The accuracy is improved, or in some scenarios, the above requirements cannot be met due to the excessive cell density, which leads to confusion when the terminal or the network recognizes the cell

Embodiment Construction

[0074] To avoid confusion during device identification, embodiments of the present invention provide a first signal sending method and device identification method.

[0075] See Figure 5 , The first signal sending method provided by the embodiment of the present invention includes the following steps:

[0076] Step 50: The sending device determines the device identification and the synchronization signal sequence to be sent;

[0077] Step 51: The sending device determines where to send the synchronization signal sequence that needs to be sent according to the determined device identification, synchronization signal sequence, and the association relationship between the device identification and the synchronization signal sequence and the physical resources used to send the synchronization signal sequence. Physical resources used;

[0078] Step 52: The sending device uses the determined physical resource to send the synchronization signal sequence to be sent.

[0079] Specifically, the...

Abstract

Embodiments of the invention disclose a method and device for signal sending and device identification and relates to the wireless communication field so as to prevent the case of confusion during device identification from happening. According to the method and device for signal sending and device identification, device identification is determined based on synchronization signal sequences and physical resources used in sending the synchronization signal sequences and / or sent control information; and compared with the conventional technical scheme that in the prior art, the device identification is determined only based on the synchronization signal sequences, the scheme in the invention extends the number of the available device identification of a system, so that the case of confusion during device identification is prevented from happening to some degree.

Description

Technical field [0001] The present invention relates to the field of wireless communication, in particular to a method and equipment for signal transmission and equipment identification. Background technique [0002] With the development of technology and the explosive growth of data services, more and more low-power base stations such as Pico and Home NodeB are deployed to provide local small coverage. The cells covered by such base stations can be Collectively referred to as small cells. Deploying small cells can not only expand the coverage of macro cells, but also increase throughput in specific areas. Generally, the more small cells are deployed in the network, the more users can be served by the small cells and enjoy the performance gains brought by the small cells, which will increase the overall network throughput. It can be expected that in actual networks, a large number of densely deployed small cells are likely to occur in geographic areas where business needs are c...
