Description

Method and equipment for measuring synchronization signal block

The embodiments of the present application relate to the field of communications, and more specifically, to methods and devices for measuring synchronization signals.

The Long Term Revolution (Long Term Revolution, LTE) system supports single carrier operation and carrier aggregation (Carrier Aggregation, CA) operation. For single carrier operation, there is only one primary synchronization signal (Primary Synchronization Signal, PSS) and secondary synchronization signal (Secondary Synchronization Signal, SSS) in the frequency domain within the system bandwidth. For carrier aggregation operations, the maximum bandwidth of the component carrier of the LTE system is 20 MHz, and there is only one PSS/SSS channel in the frequency domain in each component carrier. In particular, the 6 physical resource blocks (Physical Resource Blocks, PRBs) occupied by the PSS/SSS of the LTE system are located in the center of the system bandwidth.

At present, the 3rd Generation Partnership Project (3GPP) has reached a consensus that network equipment sends an SS burst set (Burst Set) containing multiple SS blocks to the terminal. Each SS block contains PSS, SSS and physical broadcast channel (Physical Broadcast channel, PBCH). And the frequency position of the SS block in the system bandwidth is not limited to the center frequency point of the system bandwidth. The terminal searches for the SS block in the system bandwidth to obtain time-frequency synchronization, obtains PBCH messages, and performs radio resource management (RRM) measurements.

For the New Radio (NR) system, a broadband component carrier with a large bandwidth may be supported, such as a broadband component carrier with a bandwidth of 400MHz or even 1GHz. In the same broadband component carrier, terminal devices with multiple working bandwidths will be distributed. For example, if the system bandwidth is 400MHz, there may be terminal devices with a bandwidth of 400MHz, or terminal devices with a bandwidth of 100MHz, 40MHz, or 10MHz. If there is only one SS blcok position in the broadband component carrier, a terminal device with a smaller working bandwidth may not have an SS block in its working bandwidth. And for broadband component carriers with very large bandwidths, the propagation characteristics of different frequency positions may have large differences. This requires the network equipment in the NR system to send multiple synchronization signal blocks to the terminal equipment within the broadband component carrier.

Therefore, it is necessary to provide a method for measuring synchronization signal blocks to meet the measurement requirements for synchronization signal blocks of a communication system in which a network device sends multiple synchronization signal blocks to a terminal device within a broadband component carrier.

The technical solutions in the embodiments of the present application will be clearly and completely described below in conjunction with the diagrams in the embodiments of the present application.

It should be understood that the technical solutions of the embodiments of the present application can be applied to various communication systems, such as: Global System of Mobile communication (GSM) system, Code Division Multiple Access (CDMA) system, and broadband code division Multiple access (Wideband Code Division Multiple Access, WCDMA) system, General Packet Radio Service (GPRS), Long Term Evolution (LTE) system, LTE Frequency Division Duplex (FDD) system , LTE Time Division Duplex (TDD), Universal Mobile Telecommunication System (UMTS) or Worldwide Interoperability for Microwave Access (WiMAX) communication system, 5G system, or new Wireless (New Radio, NR) system.

In the embodiments of the present application, the terminal equipment may include, but is not limited to, a mobile station (Mobile Station, MS), a mobile terminal (Mobile Terminal), a mobile telephone (Mobile Telephone), a user equipment (User Equipment, UE), and a mobile phone (handset) And portable equipment (portable equipment), vehicles (vehicle), etc., the terminal equipment can communicate with one or more core networks via a radio access network (Radio Access Network, RAN), for example, the terminal equipment can be a mobile phone (or The terminal device can also be a portable, pocket-sized, handheld, built-in computer or vehicle-mounted mobile device.

The network device involved in the embodiment of the present application is a device deployed in a wireless access network to provide wireless communication functions for terminal devices. The network device may be a base station, and the base station may include various forms of macro base stations, micro base stations, relay stations, and access points. In systems that use different wireless access technologies, the names of devices with base station functions may be different. For example, in an LTE network, it is called an evolved NodeB (evolved NodeB, eNB or eNodeB), in a third generation (3rd Generation, 3G) network, it is called a Node B (Node B), and so on.

It should be noted that, in this embodiment of the application, the terminal device measures the synchronization signal (Synchronization Signal, SS) block (block), including but not limited to reference signal receiving power (Reference Signal Receiving Power, RSRP) measurement, reference signal receiving Power (Reference Signal Receiving Power, RSRP) measurement and received signal strength indication (Received Signal Strength Indication) measurement.

Fig. 1 shows a method for measuring a synchronization signal block according to an embodiment of the present application. As shown in FIG. 1, the method 100 includes:

S110: The terminal device measures at least one synchronization signal block among multiple synchronization signal blocks transmitted in the first cell to obtain a first measurement result, and the first cell is a serving cell of the terminal device;

S120. The terminal device performs an operation corresponding to the target trigger condition according to the first measurement result and the target trigger condition, where the target trigger condition is one of multiple trigger conditions, and each trigger condition corresponds to an operation different.

Optionally, in S110, the terminal device measures the synchronization signal block used in time-frequency synchronization to obtain the first measurement result. In this case, the terminal device only needs to measure the current SS block at the beginning, avoiding the high implementation complexity caused by measuring multiple SS blocks.

Optionally, in S110, the at least one synchronization signal block measured by the terminal device is a first target synchronization signal block configured by the network device. For example, the terminal device receives a first indication message sent by the network device, where the first indication message is used to indicate the first target synchronization signal block. And it can be understood that the first target synchronization signal block indicated by the first indication message may be a synchronization signal block that the terminal device needs to use when performing time-frequency synchronization.

For example, as shown in Figure 2, the bandwidth of the broadband component carrier in the serving cell is 400MHz, and 4 SS blocks need to be transmitted in the broadband component carrier, namely synchronization signal block 1 (SS block1) and synchronization signal Block 2 (SS block2), synchronization signal block 3 (SS block3) and synchronization signal block 4 (SS block4), these 4 SS blocks are evenly distributed with a frequency interval of 100MHz. If the terminal device detects SS block1, the terminal device uses SS block1 for time-frequency synchronization and measures SS block1. Or the first indication message received by the terminal device indicates SS block2, then the terminal device measures SS block2.

Optionally, in S120, if the terminal device determines that the first measurement result meets the first trigger condition, the terminal device measures other SS blocks in the serving cell to obtain the second measurement result, or the terminal device reports to other SS blocks in the serving cell The second measurement result from the measurement. If the terminal device determines that the second measurement result meets the second trigger condition, the terminal device measures the synchronization signal block in the neighboring cell or reports the measurement result obtained by measuring the synchronization signal block in the neighboring cell. Or the terminal device determines the third measurement result according to the first measurement result and the second measurement result. If the terminal device determines that the third measurement result satisfies the third trigger condition, the terminal device measures the synchronization signal block in the neighboring cell or reports to the neighbor The measurement result obtained by measuring the synchronization signal block in the cell.

Specifically, in some embodiments, if the terminal device does not measure other SS blocks in the serving cell before determining that the first measurement result meets the first trigger condition, the terminal device measures other SS blocks in the serving cell After obtaining the second measurement result, the terminal device may also choose to report the second measurement result to the network device after the measurement. If the terminal device has already measured other SS blocks in the serving cell to obtain the second measurement result before determining that the first measurement result meets the first trigger condition, the terminal device determines that the first measurement result meets the first trigger condition. The device directly reports the second measurement result to the network device. Further, when the terminal device determines that the second measurement result satisfies the second trigger condition, or the terminal device determines that the third measurement result obtained from the first measurement result and the second measurement result satisfies the third trigger condition, the terminal device responds to the neighboring cell To measure the synchronization signal block of the neighboring cell or report the measurement result of the synchronization signal block of the neighboring cell.

As a result, the terminal device comprehensively judges the signal quality of the serving cell based on the measurement results of multiple SS blocks in the serving cell, and the judgment result is more reliable. It avoids starting neighbors in advance when the signal on some frequency domain resources of the cell is good. Cell measurement, neighbor cell measurement results reporting or cell handover, improve the performance of the communication system.

For example, the first trigger condition is event X1 (the first measurement result is worse than the first preset threshold value), and when the sum of the first measurement result and the first configuration value is less than the first preset threshold value, the terminal device considers The first measurement result meets the event X1, and when the difference between the first measurement result and the first configuration value is greater than the first preset threshold value, the terminal device considers that the first measurement result does not meet the event X1. Similarly, the second trigger condition is event X2 (the second measurement result is worse than the second preset threshold value). When the sum of the second measurement result and the second configuration value is less than the second preset threshold value, the terminal device considers the first The second measurement result meets the event X2. When the difference between the second measurement result and the second configuration value is greater than the second preset threshold value, the terminal device considers that the second measurement result does not meet the event X2. Or, the third trigger condition is event X3 (the third measurement result is worse than the third preset threshold value), and when the sum of the second measurement result and the second configuration value is less than the third preset threshold value, the terminal device considers the third The measurement result meets the event X3. When the difference between the third measurement result and the third configuration value is greater than the third preset threshold value, the terminal device considers that the third measurement result does not meet the event X3. Moreover, the aforementioned third measurement result may be an average value of the first measurement result and the second measurement result, or the third measurement result may be the maximum, minimum, or intermediate value of the first measurement and the second measurement result.

Optionally, in S120, if the terminal device determines that the first measurement result satisfies the fourth trigger condition, the terminal device measures other synchronization signal blocks in the serving cell and synchronization signal blocks in neighboring cells, or the terminal device reports to the network device Report measurement results obtained by measuring other synchronization signal blocks in the serving cell and synchronization signal blocks in neighboring cells.

For example, the network device and the terminal device may pre-book or stipulate a parameter by agreement, or the network device may configure a parameter for the terminal device through signaling. The fourth trigger condition is that the first measurement result is worse than this parameter. If the first measurement result is better than this parameter, the terminal device considers that the first measurement result does not meet the fourth trigger condition, and if the first measurement result is worse than this parameter, the terminal device considers the first measurement result to meet the fourth trigger condition.

In all the foregoing embodiments, optionally, the other synchronization signal blocks in the serving cell may be all synchronization signal blocks except the first target synchronization signal block among the multiple synchronization signal blocks transmitted in the serving cell. Taking the above four SS blocks as an example, if the first target synchronization signal block is SS block2, the other synchronization signal blocks in the serving cell are SS block1, SS block3, and SS block4.

Alternatively, other synchronization signal blocks in the serving cell may be synchronization signal blocks in a synchronization signal set designated by the network. The network device sends a second indication message to the terminal device. The second indication message indicates other synchronization signal blocks in the serving cell. For example, it may specifically indicate the number of the synchronization signal block in the frequency domain, or specifically indicate the frequency domain carrying the synchronization signal block. Resources.

Alternatively, the other synchronization signal blocks in the serving cell are synchronization signal blocks whose corresponding frequency domain positions among the multiple synchronization signal blocks transmitted in the serving cell are within the working bandwidth of the terminal device. Taking the above 4 SS blocks as an example, suppose the working bandwidth of the terminal device is 250MHz, the frequency domain positions carrying SS block1, SSblock2, and SS block3 are within the working bandwidth of the terminal device, and the first target synchronization signal block is SS block1, Then the other synchronization signal blocks in the serving cell are SS block 2 and SS block 3. Optionally, the working bandwidth of the terminal device can be understood as the bandwidth that the network device configures the terminal device to use, or the maximum bandwidth that the terminal device can support.

Optionally, in S120, if the terminal device determines that the first measurement result satisfies the fifth trigger condition, the terminal device measures the synchronization signal block in the neighboring cell or reports the measurement obtained by measuring the synchronization signal block in the neighboring cell result. In this case, the first measurement result is the measurement result obtained by the terminal device measuring the synchronization signal block used in frequency domain synchronization; or the first measurement result is the terminal device's transmission of multiple synchronization signal blocks in the serving cell Or the first measurement result is the measurement result obtained by the terminal device measuring the synchronization signal block designated by the network device, where the network device may send a third indication message to the terminal device, The third indication message indicates the synchronization signal block that the terminal device needs to measure; or the first measurement result is the measurement result obtained by the terminal device measuring all the synchronization signal blocks in the working bandwidth.

It should be noted that the various trigger conditions in the embodiments of the present application may be stipulated in the protocol, or agreed in advance by the network device and the terminal device, or notified by the network device to the terminal device through signaling.
