Description

[0001] The present application is a divisional application of the application with the application number 201710667164.3, the application date of August 7, 2017, and the title of "A method of radio link monitoring, a configuration method, a terminal and a network device". TECHNICAL FIELD

[0002] The present application relates to the technical field of communication, in particular to a method of radio link monitoring, a configuration method, a terminal and a network device. BACKGROUND

[0003] Long Term Evolution (LTE) or New Radio (NR) system both have a radio link monitoring (RLM) function, wherein, in the radio link monitoring (RLM) function of the LTE system, a terminal (UE) monitors the radio link by measuring the signal to interference plus noise ratio (SINR) of the physical downlink control channel (PDCCH) part cell reference signal (CRS).

[0004] When the measured PDCCH part CRS is lower than a preset threshold, it is determined that the radio link is in an out-of-sync state, and the physical layer notifies the upper layer (Radio Resource Control RRC layer) of an out-of-sync indication. If the RRC layer receives consecutive N out-of-sync indications, the UE starts a radio link failure timer (Timer T1).

[0005] When the measured PDCCH part CRS is higher than another threshold, it is determined that the radio link is in a sync state, and the physical layer notifies the upper layer (RRC layer) of a sync indication. If the RRC layer receives consecutive M in-sync indications, the UE stops the operation of Timer T1.

[0006] If the timer T1 runs out of time, the UE judges that the radio link fails, at which time a radio link failure event is triggered, and the UE can reinitiate the establishment of the radio link.

[0007] The number of times N and M of "out-of-sync" and "in-sync" counting in the above process are network configured, and the timeout duration of Timer T1 running is also network configurable.

[0008] The reference signal for RLM in the NR system can be different from that in the LTE system, and the channel state information reference symbol (CSI-RS) and / or a synchronization signal block (SS block) can be used as the reference signal for RLM. In this case, the reference signal can not be limited to one type of signal, and if the type of the reference signal or the related configuration of the reference signal changes, the prior art has not provided a solution for how to continue the wireless link monitoring.

[0068] To make the technical problems solved by the present application, technical solutions and advantages clearer, the following will be described in detail with reference to the drawings and specific embodiments. In the following description, specific details such as specific configurations and components are provided only to help understand the embodiments of the present application. Therefore, those skilled in the art should understand that various changes and modifications can be made to the embodiments described herein without departing from the scope and spirit of the present application. In addition, in order to be clear and concise, the description of known functions and structures is omitted.

[0069] It should be understood that the "one embodiment" or "an embodiment" mentioned throughout the specification means that the specific features, structures or characteristics related to the embodiment are included in at least one embodiment of the present application. Therefore, "in one embodiment" or "in an embodiment" appearing throughout the specification does not necessarily mean the same embodiment. In addition, these specific features, structures or characteristics can be combined in one or more embodiments in any suitable manner.

[0070] In various embodiments of the present application, it should be understood that the size of the serial number of the following processes does not mean the order of execution, and the execution order of the processes should be determined by its function and inherent logic, and should not constitute any limitation on the implementation process of the embodiments of the present application.

[0071] In a mobile communication system, multiple kinds of reference signals for radio link monitoring can be supported. For example, in an LTE system or an NR system, CSI-RS and SS block can be supported as reference signals for RLM. In the above scenarios, the kind of reference signal or the related configuration of the reference signal can change. Embodiments of the present application provide specific processing schemes for the above scenarios, and realize radio link monitoring processing in the case that the network supports multiple kinds of reference signals.

[0072] Please refer to Figure 1 In an embodiment of the present application, a method for radio link monitoring is provided, and the method is applied to a terminal, and the method comprises the following steps.

[0073] In step 11, configuration information of the reference signal for radio link monitoring is received, and the configuration information comprises configuration or change of the reference signal, and / or configuration or change of the radio link monitoring parameter of the reference signal.

[0074] Here, the terminal can receive the configuration information of the reference signal for radio link monitoring sent by a network device, and the network device can be a base station, which can be a gNB in an NR system or an eNB in an LTE system. The configuration information can comprise indication information of configuration or change of the reference signal for radio link monitoring, or can comprise indication information of configuration or change of the radio link monitoring parameter of the reference signal, or can comprise indication information of configuration of the reference signal for radio link monitoring and the radio link monitoring parameter, or can comprise indication information of change of the reference signal for radio link monitoring and the radio link monitoring parameter, etc. Here, the radio link monitoring parameter of the reference signal can be a threshold corresponding to each of the radio link synchronization counter, the radio link out-of-sync counter and the radio link failure timer, etc.

[0075] Here, configuring the reference signal can specifically include configuring a type of the reference signal. Configuring the radio link monitoring parameter of the reference signal can specifically include configuring threshold values corresponding to the radio link synchronization counter, the radio link out-of-sync counter, and the radio link failure timer. Changing the reference signal can specifically include changing the reference signal from a first reference signal in a first type of reference signal to a second reference signal in the first type of reference signal (for example, changing from CSI-RS1 to CSI-RS2), or changing the reference signal from the first reference signal in the first type of reference signal to a third reference signal in a second type of reference signal (for example, changing from SS block1 to CSI-RS1, or changing from CSI-RS1 to SS block1). Changing the radio link monitoring parameter of the reference signal can specifically include changing at least one of the threshold values corresponding to the radio link synchronization counter, the radio link out-of-sync counter, and the radio link failure timer. For example, changing the timeout value of the timer Timer T1, or changing the value of N or M, and the like.

[0076] Step 12, performing radio link monitoring according to the configuration information.

[0077] Here, the terminal performs radio link monitoring according to the configuration information sent by the network device. For example, when the configuration information indicates specific reference signals and / or radio link monitoring parameters, the terminal can perform radio link monitoring based on the corresponding reference signals and / or radio link monitoring parameters.

[0078] Through the above steps, the embodiment of the present application realizes radio link monitoring processing in the case of network supporting multiple types of reference signals. In the monitoring process, the network device can change the configuration of the reference signal, for example, change the type of the reference signal or the radio link monitoring parameter, and the terminal device can continue to perform radio link monitoring based on the changed reference signal or the radio link monitoring parameter.

[0079] For ease of description, the radio link synchronization counter, the radio link out-of-sync counter, and the radio link failure timer are collectively referred to as a statistical unit of radio link monitoring in this paper.

[0080] In the embodiment of the present application, when the configuration information in step 11 includes changing the reference signal and / or changing the radio link monitoring parameter of the reference signal, in the process of performing radio link monitoring according to the configuration information in step 12, if the statistical unit of radio link monitoring has been started when the configuration information is received, all or part of the started statistical unit can be maintained, or all or part of the started statistical unit can be reset, and radio link monitoring can be performed according to the changed reference signal and / or radio link monitoring parameter.

[0081] For example, when the reference signal is changed from CSI-RS to SS block, the terminal can reset part or all of the above-mentioned statistical units that have been started, i.e., set the count value / timing value to 0, and then re-perform relevant counting or timing processing according to the new reference signal. For example, one of the specific counting or timing methods is as follows:

[0082] When the measured PDCCH part SS block is lower than a preset threshold, it is determined that the wireless link is in an out-of-sync state, and the physical layer notifies the high layer (Radio Resource Control, RRC layer) of an out-of-sync indication. After receiving the out-of-sync indication, the RRC layer adds 1 to the count value of the wireless link synchronization counter, and can set the count value of the wireless link synchronization counter to 0. If the RRC layer receives N consecutive out-of-sync indications, the UE starts a wireless link failure timer (Timer T1).

[0083] When the measured PDCCH part SS block is higher than another preset threshold, it is determined that the wireless link is in an in-sync state, and the physical layer notifies the high layer (RRC layer) of an in-sync indication. After receiving the in-sync indication, the RRC layer adds 1 to the count value of the wireless link synchronization counter, and can set the count value of the wireless link out-of-sync counter to 0. If the RRC layer receives M consecutive in-sync indications, the UE stops the operation of Timer T1.

[0084] If the timer T1 runs out of time, the UE judges that the wireless link fails, at which time a wireless link failure event is triggered, and the UE can re-initiate the establishment of the wireless link.

[0085] For the method shown in the above Figure 1 The embodiment of the present application also provides a corresponding method flow of the network device side, please refer to Figure 2 The wireless link monitoring configuration method provided by the embodiment of the present application is applied to a network device, which can be a base station. In the NR system, the base station can be a gNB, and in the LTE system, the base station can be an eNB. As shown in the Figure 2 The method comprises the following steps.

[0086] In step 21, the configuration information of the reference signal for wireless link monitoring of the terminal is determined, and the configuration information comprises configuration or change of the reference signal, and / or configuration or change of the wireless link monitoring parameter of the reference signal.

[0087] Here, configuring the reference signal specifically can include configuring a type of the reference signal. Configuring the radio link monitoring parameter of the reference signal specifically can include configuring threshold values corresponding to the radio link synchronization counter, the radio link out-of-sync counter and the radio link failure timer. Changing the reference signal specifically can include replacing the reference signal from a first reference signal in a first type of reference signal to a second reference signal in the first type of reference signal, or replacing the reference signal from the first reference signal in the first type of reference signal to a third reference signal in a second type of reference signal. Changing the radio link monitoring parameter of the reference signal specifically can include changing at least one of the threshold values corresponding to the radio link synchronization counter, the radio link out-of-sync counter and the radio link failure timer.

[0088] At step 22, the terminal is sent the configuration information.

[0089] The network device sends the configuration information to the terminal, so that the terminal can perform radio link monitoring based on the configuration information.

[0090] Based on the above method, the embodiment of the present application further provides a terminal 30, as shown in the figure, comprising: Figure 3

[0091] The configuration receiving module 31 is configured to receive configuration information of a reference signal for radio link monitoring, the configuration information comprising configuration or change of the reference signal, and / or configuration or change of a radio link monitoring parameter of the reference signal.

[0092] The link monitoring module 32 is configured to perform radio link monitoring according to the configuration information.

[0093] Here, the link monitoring module 32 can comprise:

[0094] The monitoring processing unit 321 is configured to, when the configuration information comprises change of the reference signal and / or change of the radio link monitoring parameter of the reference signal, maintain or reset all or part of the statistical units that have been started upon receiving the configuration information, and perform radio link monitoring according to the changed reference signal and / or radio link monitoring parameter, wherein the statistical units comprise the radio link synchronization counter, the radio link out-of-sync counter and the radio link failure timer.

[0097] The input unit 430 can be configured to receive information input by a user and generate a signal for controlling user settings and functions of the terminal 400. Specifically, the input unit 430 can include a touch panel 431. The touch panel 431, also known as a touch screen, can collect a touch operation (e.g., an operation of a user using a finger, a stylus, or any suitable object or accessory on or near the touch panel 431) and drive a corresponding connection device according to a pre-set program. Optionally, the touch panel 431 can include a touch detection device and a touch controller. The touch detection device detects a touch position of a user and detects a signal generated by a touch operation and transmits the signal to the touch controller. The touch controller receives the touch information from the touch detection device, converts the touch information into touch coordinates, and transmits the touch coordinates to the processor 450. The touch controller can also receive a command from the processor 450 and execute the command. In addition, the touch panel 431 can be implemented in various types such as a resistive type, a capacitive type, an infrared type, and a surface acoustic wave type. In addition to the touch panel 431, the input unit 430 can include another input device 432. The another input device 432 can include one or more of a physical keyboard, a function key (e.g., a volume control key, an on / off key, or the like), a trackball, a mouse, a joystick, or the like.

[0098] The display unit 440 can be configured to display information input by a user or information provided to the user and various menu interfaces of the terminal 400. The display unit 440 can include a display panel 441. The display panel 441 can be implemented in various types such as an LCD or an OLED.

[0099] It should be noted that the touch panel 431 can cover the display panel 441 to form a touch display screen. When the touch display screen detects a touch operation on or near the touch display screen, the touch display screen transmits a signal to the processor 450 to determine a type of the touch event. Subsequently, the processor 450 provides a corresponding visual output on the touch display screen according to the type of the touch event.

[0100] The touch display screen comprises an application interface display area and a common control display area. The arrangement of the application interface display area and the common control display area is not limited, and can be arranged in an up-down manner, a left-right manner or any other manner that can distinguish the two display areas.

The application interface display area can also be an empty interface without any content. The common control display area is used to display controls with high usage rate, such as a setting button, interface number, a scroll bar, an application icon of a phone book and the like.

[0101] The processor 450 is the control center of the terminal device, connects all parts of the mobile phone through various interfaces and lines, executes various functions of the terminal device and processes data by running or executing software programs and / or modules stored in the first memory 421 and calling data stored in the second memory 422, thereby monitoring the terminal device as a whole. Optionally, the processor 450 can include one or more processing units.

[0102] In the embodiment of the application, by calling the software programs and / or modules stored in the first memory 421 and the data stored in the second memory 422, the processor 450 is configured to receive configuration information of a reference signal for radio link monitoring, wherein the configuration information comprises configuration or change of the reference signal and / or configuration or change of radio link monitoring parameters of the reference signal; and perform radio link monitoring according to the configuration information.

[0109] Figure 6 is a structural diagram of the network device of the embodiment of the present application, which can realize the details of the above-mentioned configuration method of wireless link monitoring applied to the network device and achieve the same effect. As shown in the figure, Figure 6 the network device 600 comprises a processor 601, a transceiver 602, a memory 603 and a bus interface, wherein:

[0110] the processor 601 is configured to read the program in the memory 603 and execute the following processes: determining configuration information of a reference signal for wireless link monitoring by the terminal, the configuration information comprising configuration or change of the reference signal, and / or configuration or change of a wireless link monitoring parameter of the reference signal; and sending the configuration information to the terminal.

[0111] In the Figure 6 bus architecture can comprise any number of interconnected buses and bridges, which are collectively represented by the processor 601 and the memory 603, and various circuit links of one or more processors represented by the processor 601 and the memory represented by the memory 603. The bus architecture can also link various other circuits such as peripheral devices, voltage stabilizers and power management circuits, which are well known in the art, and thus, further description thereof will not be given herein. The bus interface provides an interface. The transceiver 602 can be a plurality of elements, i.e. comprising a transmitter and a receiver, which provide units for communicating with various other devices on a transmission medium.

[0112] The processor 601 is responsible for managing the bus architecture and general processing, and the memory 603 can store data used by the processor 601 when performing operations.

[0113] The embodiment of the present application can support wireless link monitoring of two types of reference signals. Specifically, a set of statistical units can be set based on the two types of reference signals, and the timers / counters in the same set of statistical units are timed / counted based on the measurement results of the two types of reference signals. Alternatively, a set of independent statistical units can be set for each type of reference signal, i.e. each type of reference signal is independently timed / counted.

[0114] Please refer to Figure 7 the other method of wireless link monitoring provided by the embodiment of the present application, which is applied to a terminal and comprises:

[0115] Step 71, receiving configuration information of reference signals for radio link monitoring, the configuration information including indication information of two types of reference signals for radio link monitoring.

[0116] Here, the two types of reference signals can be CSI-RS and SS block, or a combination of other reference signals, such as DMRS, etc.

[0117] Step 72, performing radio link monitoring according to the two types of reference signals indicated in the configuration information.

[0118] Here, when performing radio link monitoring based on the two types of reference signals, a set of statistical units can be set for the two types of reference signals, and the timers / counters in the same set of statistical units are timed / counted based on the measurement results of the two types of reference signals, or a set of independent statistical units can be set for each type of reference signal, i.e., each type of reference signal is independently timed / counted.

[0119] Specifically, when a set of statistical units is set, if a link synchronization is monitored on any one of the two types of reference signals, the count value of the radio link synchronization counter is increased by 1 (at this time, the radio link out-of-sync timer can also be set to zero), and when the count value of the radio link synchronization counter reaches a first threshold, the radio link failure timer is reset or stopped.

[0120] When a link out-of-sync is monitored on any one of the two types of reference signals, the count value of the radio link out-of-sync counter is increased by 1 (at this time, the radio link synchronization timer can also be set to zero), and when the count value of the radio link out-of-sync counter reaches a second threshold, the radio link failure timer is started.

[0121] When two sets of independent statistical units are set, i.e., a corresponding radio link synchronization counter, a radio link out-of-sync counter and a radio link failure timer are set for each type of reference signal, the radio link synchronization counter or the radio link out-of-sync counter corresponding to each type of reference signal can be counted according to the link synchronization or the link out-of-sync monitored by each type of reference signal, and when the radio link failure counter corresponding to any one type of reference signal reaches the corresponding threshold, or when the radio link failure counters corresponding to the two types of reference signals all reach the corresponding thresholds, a radio link failure is determined, at which time a radio link failure event can be triggered, and the terminal can re-initiate the establishment process of the radio link.

[0122] Further, when the radio link failure timer corresponding to any one type of reference signal reaches the corresponding threshold, the terminal can also report a notification message of the reference signal radio link failure corresponding to the any one type of reference signal to the network.

[0149] The configuration determination module 111 is configured to determine configuration information of reference signals for wireless link monitoring of a terminal, wherein the configuration information comprises indication information of two types of reference signals for wireless link monitoring.

[0150] The configuration sending module 112 is configured to send the configuration information to the terminal.

[0151] Figure 12 is another structural diagram of a network device of an embodiment of the present application, which can implement the details of the above-mentioned configuration method for wireless link monitoring applied to a network device and achieve the same effect. As shown in the figure, the network device 1200 comprises a processor 1201, a transceiver 1202, a memory 1203 and a bus interface, wherein: Figure 12

[0152] The processor 1201 is configured to read a program in the memory 1203 and execute the following processes: determining configuration information of reference signals for wireless link monitoring of a terminal, wherein the configuration information comprises indication information of two types of reference signals for wireless link monitoring; and sending the configuration information to the terminal.

[0153] In Figure 12 ​​In particular embodiments, the bus architecture can include any number of interconnecting buses and bridges, depending on the specific application of the processor 1201 and the memory 1203 that are linked together by the various circuits, represented generally by the processor 1201 and the memory. The bus architecture can also link various other circuits such as peripheral devices, voltage regulators, and power management circuits, which are well known in the art and thus, not described further. The bus interface provides an interface. The transceiver 1202 can be a plurality of elements, including a transmitter and a receiver, that provides a means for communicating with various other apparatus over a transmission medium.

[0154] The processor 1201 is responsible for managing the bus architecture and general processing, while the memory 1203 can store the data used by the processor 1201 in executing its operations.

[0155] In practical applications, a terminal can be configured with one reference signal for radio link monitoring, and if the configured reference signal is deactivated, the terminal can determine whether to switch to another reference signal for radio link monitoring. A specific example of the above scenario can be in Figure 1 As shown in the configuration information in step 11, only one reference signal is configured, and after step 12, the terminal can receive a deactivation instruction for the reference signal sent by the network device. Please refer to Figure 13 The embodiment of the present application provides a radio link monitoring method, applied to a terminal, and including the following steps.

[0156] Step 131, when performing radio link monitoring according to a pre-configured first reference signal, receiving a deactivation command for the first reference signal.

[0157] Here, the deactivation command can be sent by the network side to the terminal, or can be generated by the terminal itself. For example, the terminal can receive the deactivation command sent by the network device through RRC signaling, MAC signaling or physical layer signaling. The deactivation command can be a deactivation command for the reference signal itself, that is, directly deactivating a certain reference signal, or a deactivation command for the time-frequency resource corresponding to the reference signal, or a deactivation command for the cell corresponding to the reference signal.

[0158] Step 132, executing or ignoring the deactivation command according to whether the first reference signal is allowed to be deactivated.

[0159] Here, the terminal can execute or ignore the deactivation command according to a pre-obtained configuration parameter of whether the first reference signal is allowed to be deactivated. The configuration parameter can be pre-agreed and configured on the terminal side, or can be configured by the network device.

[0160] Specifically, when the first reference signal is allowed to be deactivated in the pre-configured manner, the terminal can switch to the second reference signal to listen for wireless links. When switching to the second reference signal to listen for wireless links, all or some of the started statistical units are maintained or reset. The statistical units include a wireless link synchronization counter, a wireless link out-of-sync counter, and a wireless link failure timer.

[0161] When the pre-configured first reference signal does not allow deactivation, the terminal can ignore the deactivation command and continue to listen for the wireless link on the first reference signal.

[0162] For example, the first reference signal can be CSI-RS1, and the second reference signal can be CSI-RS2. The terminal can switch from CSI-RS1 to CSI-RS2 for radio link monitoring based on a deactivation command. Alternatively, the first reference signal can be CSI-RS1, and the second reference signal can be SS block 1, or the first reference signal can be SS block 1, and the second reference configuration signal can be SS block 2, etc. The second reference signal can be pre-configured by the network, or the UE can find a reference signal itself based on certain criteria. For example, it could be the SS block reference signal on the PDCCH beam that the UE is currently monitoring.

[0163] As one implementation method, steps 131-132 above can be performed in... Figure 1 Execute after step 12.

[0164] Based on the above methods, this embodiment of the invention also provides a corresponding network device configuration process, please refer to... Figure 1 4. This embodiment of the invention provides a configuration method for wireless link monitoring, applied to a network device, including:

[0165] Step 141: Send a deactivation command for the first reference signal of the wireless link listening to the terminal.

[0166] Here, the network device can send the deactivation command to the terminal via RRC signaling, MAC signaling, or physical layer signaling. The deactivation command can be a deactivation command targeting the reference signal itself, i.e., directly deactivating a certain reference signal; it can also be a deactivation command targeting the time-frequency resources corresponding to the reference signal; or it can be a deactivation command targeting the cell corresponding to the reference signal.

[0167] Based on the above methods, embodiments of the present invention also provide terminals and network devices for implementing the above methods. Please refer to... Figure 15 This invention provides a terminal 150, comprising:

[0168] The command receiving module 151 is configured to receive a deactivation command for a first reference signal when performing radio link monitoring according to the first reference signal.

[0169] The command executing module 152 is configured to execute or ignore the deactivation command according to whether the first reference signal is allowed to be deactivated.

[0170] The command executing module 152 includes:

[0171] The first processing unit 1521 is configured to switch the terminal to perform radio link monitoring on a second reference signal when the first reference signal is allowed to be deactivated.

[0172] The second processing unit 1522 is configured to ignore the deactivation command and continue to perform radio link monitoring on the first reference signal when the first reference signal is not allowed to be deactivated.
