Problems solved by technology

That is to say, there is no technical solution for how to transmit STRS in the prior art, which makes it impossible to realize the transmission of STRS in the new carrier
[0005] For the above-mentioned problems in related technologies, no effective solution has been proposed yet

Embodiment 1

[0114] This embodiment proposes a STRS configuration and signaling method, which is used in a new carrier. Specifically, the base station and UE agree to adopt a fixed period for STRS transmission, such as 2ms, 3ms, 5ms, or 10ms. Here Taking into account the purpose of STRS, and then through a large number of simulation evaluations, it is believed that a fixed value of 5ms for the LTE system is the optimal choice, which can balance performance and overhead. On the basis of a fixed period, the base station further configures the subframe pattern of the STRS in the radio frame through signaling, and sends the signaling to the UE through the carrier paired with the carrier carrying the STRS. The subframe pattern here is used to describe the STRS carried in the radio frame or in the carrier.

[0115] There are two specific implementation methods:

[0116] In the first way, a subframe offset parameter is added to describe the subframe pattern on the basis of the STRS fixed period. For ...

Abstract

The invention provides a sending processing method and device of synchronization track reference signals. The sending processing method includes that step 1, sub-frame pattern information for the synchronization track reference signals is configured for a new carrier through a base station, wherein the sub-frame pattern information is used for describing sub-frames which are arranged in wireless frames and used for sending the STRS (Synchronization Track Reference Signals) and step 2, the base station sends the configured sub-frame pattern information to the user equipment. According to the technical scheme of the sending processing method and device of the synchronization track reference signals, the technical problems that the STRS cannot be sent in the new carrier due to the fact that the related technologies are free of the technical scheme about how to send the STRS yet and the like are solved and accordingly the STRS can be sent in the new carrier.

Description

Technical field [0001] The present invention relates to the field of communications, and in particular to a method and device for sending and processing synchronous tracking reference signals. Background technique [0002] With the development of the mobile communication industry and the continuous growth of demand for mobile data services, people have higher and higher requirements for the speed and quality of service (Quality of Service, referred to as QoS) of mobile communication, so in the third generation of mobile communication (3G) Before large-scale commercial use, the research and development of the next-generation mobile communication system has already begun. A typical example is the long-term launch of the 3rd Generation Partnership Project (3GPP). In the Long-Term Evolution (LTE) project, the highest spectrum bandwidth that the LTE system can provide is 20 MHz (megahertz). With the further evolution of the network, Long-Term Evolution Advance (LTE-A), as an evolutio...
