Problems solved by technology

[0003] However, using the above solution, the low-quality downlink signal penetrating through the car window becomes the co-source interference signal of the above-mentioned useful signal. If the UE receives the co-source interference signal before the useful signal, it will Decoding, still may cause communication failure between the two parties

Embodiment Construction

[0029] The technical solutions in the embodiments of the present invention will be described below with reference to the drawings in the embodiments of the present invention.

[0030] In the description of the present invention, unless otherwise specified, " / " means "or", for example, A / B may mean A or B. The "and / or" in this article is just an association relationship describing associated objects, which means that there can be three relationships, for example, A and / or B, which can mean: A exists alone, A and B exist at the same time, and B exists alone These three situations. In addition, "at least one" and "plurality" mean two or more. Words such as "first" and "second" do not limit the number and order of execution, and words such as "first" and "second" do not necessarily limit the difference.

[0031] The signal relay method and signal identification provided by the embodiments of the present invention can be applied to a wireless communication system. figure 1 A sch...

Abstract

Disclosed are a signal relay method, a signal identification method, apparatus and device, which relate to the technical field of communications, are used for determining useful signals in a wireless communication environment, and comprise: receiving a wireless signal, and demodulating the wireless signal to obtain a media access control (MAC) layer data packet corresponding to the wireless signal; analyzing the MAC layer data packet to determine a preset bit in an MAC layer packet header, wherein the MAC layer packet header is located in the MAC layer data packet; and under the condition that the preset bit is the preset numerical value, determining that the wireless signal is the signal amplified by the signal relay equipment. The embodiment of the invention is applied to a high-speed running communication environment.

Description

technical field [0001] The present invention relates to the field of communication technology, in particular to a signal relay method, a signal identification method, a device and equipment. Background technique [0002] At present, in the wireless communication environment, when the wireless penetration loss is large (such as a train passing through a tunnel), in order to ensure the signal quality between the communication parties, a wireless relay scheme can be used between the user equipment (UE) and Relay amplification of wireless signals is performed between base stations. Specifically, taking the UE on the train receiving the downlink signal of the base station as an example, a repeater is installed on the train, and the repeater receives the downlink signal sent by the station, and performs relay amplification processing on the downlink signal. Further, the repeater sends the amplified and processed downlink signal to the UE as a useful signal, so as to ensure the si...
