Description
This application claims Patent Office of the People's Republic of China was submitted on February 20th, 2017, application No. is 201710091251.9, a kind of priority of the Chinese patent application of entitled " method and apparatus for the synchronization signal for monitoring LAA-NR ", entire contents are hereby incorporated by reference in the application.
This application involves wireless communication technology field more particularly to the monitor methods and equipment of a kind of synchronization signal.
With flourishing for mobile communication technology, the outburst of demand of the public to high-bandwidth communication business is becoming increasingly acute with the rare contradiction of licensed spectrum resource.In order to solve the rare crisis of current licensed spectrum; third generation partner program (3rd Generation Partnership Project; 3GPP) propose the concept of license auxiliary access (Licensed-Assisted Access, LAA).LAA technology is that long term evolution (Long TermEvolution, LTE) frequency spectrums of operation can be extended to from licensed spectrum and exempt from licensed spectrum by one kind, and exempt from the technology that licensed spectrum is communicated by licensed spectrum auxiliary control.
In the LTE system (also known as LAA-LTE system) using LAA technology, it polymerize (Carrier Aggregation by licensed band and the effective carrier wave for exempting from licensed band, CA), the license carrier wave in licensed band is configured as main carrier, and it configures and exempts to exempt from license carrier wave as secondary carrier in licensed band, mobile broadband (Mobile Broadband) network capacity can be expanded, improve the availability of frequency spectrum of system.
In LAA-LTE system, listem-before-talk (Listen Before Talk, LBT) mechanism of the equipment (Load-Based Equipment, LBE) based on load can be followed using the base station of secondary carrier (or exempting to permit carrier wave).The LBE mechanism are as follows: base station using secondary carrier (including transmit data or synchronization signal (Synchronization Signal needing to be communicated with terminal device, the contents such as SS)) in the case where, before the channel in access secondary carrier resource, it needs to carry out clear channel assessment (CCA) (Clear Channel Assessment to the channel, CCA it) detects, if testing result is channel idle, which can be communicated on this channel;If testing result is channel busy, base station continues to execute clear channel assessment (CCA) (Extended CCA, the ECCA) detection of extension.The ECCA is detected as one CCA detection of the base station generation and keeps out of the way times N, and the base station needs to be communicated on this channel when the testing result that subsequent n times CCA is detected is channel idle.
The advantages of flexibly being eated dishes without rice or wine due to new wireless (New Radio, NR) technical support, is also the development trend of mobile communication system using NR technology therefore.Neatly synchronous transmission of signal is supported using the mobile communication system of NR technology, i.e. synchronization signal can be by way of synchronization signal block (SS block), synchronization signal batch (SS burst), synchronization signal batch set (SS burst set), and can be sent with a variety of sending methods;Wherein include multiple SS burst in SS burst set, include multiple SS block in a SS burst, includes multiple synchronization signals in a SS block.
For example, the base station can send synchronization signal using omnidirectional's sending method when the carrier wave that base station uses is in low-frequency range (less than 6 Gigahertzs (GHz)).When the carrier wave that base station uses is in high band (being greater than 6GHz), the base station can send synchronization signal using half omnidirectional's sending method or directive sending mode.
According to discussed above it is found that (being properly termed as LAA-NR using the mobile communication system of LAA technology and NR technology at the same time
System), using the base station of secondary carrier before sending synchronization signal, need to the channel in secondary carrier resource using LBE LBT mechanism carry out Channel Detection, and determine meet channel access condition after, could on channel using certain sending method send synchronization signal.Due to that can have multiple base stations using different secondary carriers in LAA-NR system, therefore the secondary carrier that each base station uses is not fixed, therefore, terminal device can not determine the secondary carrier that each base station uses, neatly synchronous transmission of signal is supported additionally, due to the system, therefore, each base station using secondary carrier can not also be determined using which kind of sending method terminal device.
In summary, terminal device in LAA-NR system, which can not be determined, sends the channel that synchronization signal occupies using the base station of secondary carrier, also the sending method for the transmission synchronization signal that base station uses can not be determined, i.e. terminal device can not determine when, how receive synchronization signal on which channel, the monitoring efficiency that this results in terminal device to monitor synchronization signal is lower, further influences the access performance and service feature of terminal device.

The embodiment of the present application provides a kind of monitor method of synchronization signal, and this method can be, but not limited to suitable for mobile communication system as shown in Figure 4, as shown in fig.5, the process of this method includes:
S501: base station is detected to the channel on license carrier wave of exempting from that licensed cells use is exempted from, the cell exempted from the use that licensed cells are the base station maintenance and exempt from license carrier wave.
Optionally, the base station is to safeguard the base station 402b or base station 402c having in the base station for exempting from licensed cells, such as mobile communication system shown in Fig. 4.In addition, the base station can safeguard a cell, i.e., it is described to exempt from licensed cells;Or the base station maintenance can include described exempting from licensed cells with multiple cells, in the multiple cell.
Optionally, the base station can use traditional LBE mechanism, and realization detects the channel.
For example, the base station can use the LBT mechanism of LBE, realization detects the channel, and detailed process is as follows:
The base station, which carries out CCA detection to the channel, can access the channel if detecting the channel idle;
If detecting the channel busy, the base station executes ECCA detection: the base station generates an Integer N in setting value range [1, q] at random, and N is that number is kept out of the way in CCA detection;
