Problems solved by technology

[0010] Both of the above two methods face challenges in the unlicensed spectrum. In method A, if the discovery signal is sent periodically, it may face severe interference. Higher burden (such as energy consumption) and detection performance degradation; method B requires UE to send uplink signals in unlicensed spectrum will bring greater interference and overhead; method C is between the PCC and the SCC There are challenges when there is a non-ideal backhaul (Backhaul) - that is, the SCC cannot be scheduled in real time

Abstract

The invention provides a scheduling method and a scheduling device for an unlicensed spectrum. In an embodiment, a base station sends a first signal on a first resource of a first serving cell and sends a second signal on a second resource of a second carrier, wherein the first serving cell is deployed on a licensed carrier, the second carrier is deployed on an unlicensed carrier, and the port of a transmitting antenna of the first signal and the port of a transmitting antenna for cell identifying information of the first serving cell are not co-located. When a primary component carrier (PCC) is deployed on a licensed carrier frequency, a secondary component carrier (SCC) is deployed on an unlicensed carrier frequency, and a return link between the PCC and the SCC is nonideal, the SCC scheduling problem arises. The method solves the SCC scheduling problem, prevents interference on the SCC, and reduces the measurement overhead of user equipment (UE).

Description

technical field [0001] The present invention relates to a scheduling scheme in a wireless communication system, in particular to a scheduling scheme based on a long-term evolution (LTE-LongTerm Evolution) unlicensed spectrum (Unlicensed Spectrum). Background technique [0002] In the traditional 3GPP–3rd Generation Partner Project (3GPP–3rd Generation Partner Project) LTE system, data transmission can only occur on the licensed spectrum. However, with the rapid increase of traffic, especially in some urban areas, the licensed spectrum may be difficult Meet the needs of business volume. The 62nd plenary meeting of 3GPP RAN discussed a new research topic, that is, the research on unlicensed spectrum synthesis (RP-132085), the main purpose of which is to study the non-standalone (Non-standalone) deployment of LTE on unlicensed spectrum, the so-called Non-independent means that the communication on the unlicensed spectrum must be associated with the serving cell on the licensed...
