Description
Technical Field
The embodiments of the present application relate to the field of communications, and more particularly, to a method and apparatus for measuring a synchronization signal.
Background
Long Term Evolution (LTE) systems support single Carrier operation and Carrier Aggregation (CA) operation. For single carrier operation, only one Primary Synchronization Signal (PSS) and one Secondary Synchronization Signal (SSS) exist in the system bandwidth as viewed from the frequency domain. For carrier aggregation operation, the maximum bandwidth of the component carrier of the LTE system is 20MHz, and only one PSS/SSS channel exists in each component carrier in the frequency domain. In particular, 6 Physical Resource Blocks (PRBs) occupied by PSS/SSS of the LTE system are located at the center of the system bandwidth.
Currently, a third Generation Partnership Project (3 GPP) has agreed that a network device sends a terminal a SS Burst Set (Burst Set) including a plurality of SS blocks (blocks), each of which includes a PSS, a SSs, and a Physical Broadcast Channel (PBCH). And the frequency position of the SS block in the system bandwidth is not limited to the central frequency point position of the system bandwidth. The terminal searches SSblock in the system bandwidth to obtain time-frequency synchronization, obtains PBCH information and carries out Radio Resource Management (RRM) measurement.
For a New Radio (NR) system, a wideband component carrier with a large bandwidth, such as a wideband component carrier with a bandwidth of 400MHz or even 1GHz, may be supported. Terminal devices with various working bandwidths can be distributed in the same broadband member carrier, for example, if the system bandwidth is 400MHz, terminal devices with 400MHz bandwidths can be distributed, and terminal devices with 100MHz, 40MHz, and 10MHz bandwidths can also be distributed. A terminal device with a smaller operating bandwidth may not have an SS block within its operating bandwidth if there is only one SS blcok location within the wideband component carrier. And for a wideband component carrier with very large bandwidth, the propagation characteristics of different frequency locations may have large differences. This requires the network device in the NR system to transmit multiple blocks of synchronization signals to the terminal device within the wideband component carrier.
Therefore, it is desirable to provide a method for measuring a synchronization signal block, which satisfies the requirement of a communication system in which a network device sends a plurality of synchronization signal blocks to a terminal device within one wideband component carrier for measuring the synchronization signal block.

Detailed Description
The technical solutions in the embodiments of the present application will be clear and fully described below with reference to the accompanying drawings in the embodiments of the present application.
It should be understood that the technical solutions of the embodiments of the present application may be applied to various communication systems, for example: a Global System for Mobile communications (GSM) System, a Code Division Multiple Access (CDMA) System, a Wideband Code Division Multiple Access (WCDMA) System, a General Packet Radio Service (GPRS), a Long Term Evolution (Long Term Evolution, LTE) System, an LTE Frequency Division Duplex (FDD) System, an LTE Time Division Duplex (TDD), a Universal Mobile Telecommunications System (UMTS) or a Worldwide Interoperability for Microwave Access (WiMAX) communication System, a 5G System, or a New Radio (NR) System.
In the embodiment of the present application, the Terminal device may include, but is not limited to, a Mobile Station (MS), a Mobile Terminal (Mobile Terminal), a Mobile phone (Mobile Telephone), a User Equipment (UE), a handset (handset), a portable device (portable Equipment), a vehicle (vehicle), and the like, and the Terminal device may communicate with one or more core networks through a Radio Access Network (RAN), for example, the Terminal device may be a Mobile phone (or referred to as a "cellular" phone), a computer with a wireless communication function, and the Terminal device may also be a portable, pocket, handheld, computer-embedded, or vehicle-mounted Mobile apparatus.
The network device according to the embodiment of the present application is a device deployed in a radio access network to provide a wireless communication function for a terminal device. The network device may be a base station, and the base station may include various macro base stations, micro base stations, relay stations, access points, and the like. In systems employing different radio access technologies, the names of devices having a base station function may differ. For example, in an LTE network, referred to as an Evolved node B (eNB or eNodeB), in a third Generation (3rd Generation, 3G) network, referred to as a node B (node B), and so on.
In the embodiment of the present application, the terminal device measures a Synchronization Signal (SS) block (block), including but not limited to measuring Reference Signal Received Power (RSRP), and measuring Received Signal Strength indicator (Received Signal Strength Indication).
Fig. 1 illustrates a method of measuring a synchronization signal block according to an embodiment of the present application. As shown in fig. 1, the method 100 includes:
s110, a terminal device measures at least one synchronous signal block in a plurality of synchronous signal blocks transmitted in a first cell to obtain a first measurement result, wherein the first cell is a service cell of the terminal device;
and S120, the terminal device executes an operation corresponding to the target trigger condition according to the first measurement result and the target trigger condition, wherein the target trigger condition is one of a plurality of trigger conditions, and the operation corresponding to each trigger condition is different.
Optionally, in S110, the terminal device measures a synchronization signal block used in time-frequency synchronization to obtain a first measurement result. Under the condition, the terminal equipment only needs to measure the current SS block at first, so that higher implementation complexity caused by measuring a plurality of SS blocks is avoided.
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 first indication information sent by the network device, where the first indication information is used to indicate the first target synchronization signal block. And it is understood that this first target synchronization signal block indicated by the first indication information may be a synchronization signal block that the terminal device needs to use when performing time-frequency synchronization.
For example, as shown in fig. 2, the bandwidth of the wideband component carrier in the serving cell is 400MHz, and 4 SS blocks need to be transmitted in the wideband component carrier, namely, a synchronization signal block 1(SS block1), a synchronization signal block 2(SSblock2), a synchronization signal block 3(SS block3), and a synchronization signal block 4(SS block4), and the 4 SS blocks are uniformly distributed at a frequency interval of 100 MHz. If the terminal device detects SS block1, the terminal device uses SS block1 to perform time-frequency synchronization and measures SS block 1. Or the first indication information received by the terminal device indicates SS block2, the terminal device measures SS block 2.
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 a second measurement result, or the terminal device reports the second measurement result obtained by measuring other SS blocks in the serving cell. And if the terminal equipment determines that the second measurement result meets the second trigger condition, the terminal equipment measures the synchronous signal blocks in the adjacent cell or reports the measurement result obtained by measuring the synchronous signal blocks in the adjacent cell. Or the terminal device determines a third measurement result according to the first measurement result and the second measurement result, and if the terminal device determines that the third measurement result meets a third trigger condition, the terminal device measures the synchronization signal blocks in the neighboring cell or reports the measurement result obtained by measuring the synchronization signal blocks in the neighboring 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 satisfies the first trigger condition, the terminal device measures other SS blocks in the serving cell to obtain a second measurement result, and the terminal device may further select to report the second measurement result to the network device after the measurement. If the terminal device measures other SS blocks in the serving cell to obtain a second measurement result before determining that the first measurement result satisfies the first trigger condition, the terminal device directly reports the second measurement result to the network device when determining that the first measurement result satisfies the first trigger condition. Further, when the terminal device determines that the second measurement result satisfies the second trigger condition, or the terminal device determines that a third measurement result obtained from the first measurement result and the second measurement result satisfies the third trigger condition, the terminal device measures the synchronization signal block in the neighboring cell or reports the measurement result of the synchronization signal block in the neighboring cell.
Therefore, the terminal equipment comprehensively judges the signal quality of the serving cell according to the measurement results of the plurality of SS blocks in the serving cell, the judgment result is more reliable, the measurement of the adjacent cell, the report of the measurement result of the adjacent cell or the cell switching is prevented from being started in advance under the condition that the signal on the frequency domain resource of the cell is good, and the performance of the communication system is improved.
For example, the first trigger condition is an event X1 (the first measurement result is worse than a first preset threshold), when the sum of the first measurement result and the first configuration value is smaller than the first preset threshold, the terminal device considers that the first measurement result satisfies the event X1, and when the difference between the first measurement result and the first configuration value is larger than the first preset threshold, the terminal device considers that the first measurement result does not satisfy the event X1. Similarly, the second trigger condition is event X2 (the second measurement result is worse than the second preset threshold), when the sum of the second measurement result and the second configuration value is smaller than the second preset threshold, the terminal device considers that the second measurement result satisfies event X2, and when the difference between the second measurement result and the second configuration value is larger than the second preset threshold, the terminal device considers that the second measurement result does not satisfy event X2. Or, the third trigger condition is an event X3 (the third measurement result is worse than a third preset threshold), when the sum of the second measurement result and the second configuration value is smaller than the third preset threshold, the terminal device regards that the third measurement result satisfies the event X3, and when the difference between the third measurement result and the third configuration value is larger than the third preset threshold, the terminal device regards that the third measurement result does not satisfy the event X3. Also, the 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 a maximum value, a minimum value, or an intermediate value among the first measurement result 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 the neighboring cell, or the terminal device reports, to the network device, a measurement result obtained by measuring other synchronization signal blocks in the serving cell and synchronization signal blocks in the neighboring cell.
For example, the network device and the terminal device may preset or protocol a parameter, or the network device may configure a parameter for the terminal device through signaling. The fourth trigger condition is that the first measurement is worse than this parameter. And if the first measurement result is better than the parameter, the terminal equipment considers that the first measurement result does not satisfy the fourth trigger condition, and if the first measurement result is worse than the parameter, the terminal equipment considers that the first measurement result satisfies the fourth trigger condition.
In all the above embodiments, optionally, the other synchronization signal blocks in the serving cell may be all the synchronization signal blocks except the first target synchronization signal block among the plurality of synchronization signal blocks transmitted in the serving cell. Taking the above 4 ssblocks as an example, if the first target synchronization signal block is SS block2, the other synchronization signal blocks in the serving cell are SSblock1, SS block3, and SS block 4.
Alternatively, the other synchronization signal blocks in the serving cell may be synchronization signal blocks in a network-specified set of synchronization signals. The network device sends second indication information to the terminal device, where the second indication information indicates other synchronization signal blocks in the serving cell, and for example, may specifically indicate the number of the synchronization signal block on the frequency domain, or specifically indicate the frequency domain resource carrying the synchronization signal block.
Or, the other synchronization signal blocks in the serving cell are synchronization signal blocks of which the corresponding frequency domain positions in the multiple synchronization signal blocks transmitted in the serving cell are within the operating bandwidth of the terminal device. Taking the above 4 SS blocks as an example, assuming that the operating bandwidth of the terminal device is 250MHz, the frequency domain locations carrying SS block1, SS block2, and SS block3 are within the operating 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 SSblock2 and SS block 3. Alternatively, the operating bandwidth of the terminal device may be understood as the bandwidth that the network device configures the terminal device to be able 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 meets the fifth trigger condition, the terminal device measures the synchronization signal block in the neighboring cell or reports a measurement result obtained by measuring the synchronization signal block in the neighboring cell. In this case, the first measurement result is a measurement result obtained by measuring, by the terminal device, a synchronization signal block used when performing frequency domain synchronization; or the first measurement result is a measurement result obtained by measuring all the synchronous signal blocks in the plurality of synchronous signal blocks transmitted in the serving cell by the terminal equipment; or the first measurement result is a measurement result obtained by measuring a synchronization signal block specified by the network device by the terminal device, where the network device may send third indication information to the terminal device, and the third indication information indicates the synchronization signal block that the terminal device needs to measure; or the first measurement result is a measurement result obtained by the terminal device measuring all the synchronous signal blocks in the working bandwidth.
It should be noted that, the multiple trigger conditions in the embodiment of the present application may be specified by a protocol, may be agreed in advance by the network device and the terminal device, and may be notified to the terminal device by the network device through a signaling.
