Description

Resource scheduling method and terminal device Technical field

The present application relates to the field of task scheduling, and in particular, to a resource scheduling method and a terminal device.

Background technique

With the development of communication technologies, more and more communication systems have emerged, from 2G communication systems (such as Global System for Mobile Communications (GSM)) to 3G communication systems (such as time-division synchronous code division multiple access systems). (Time Division-Synchronization Code Division Multiple Access (TD-SCDMA)), from 3G communication systems to 4G communication systems (such as Long Term Evolution (LTE)), and even to 5G communication systems (such as new air ports) (New Radio, NR) system). When a new communication system/air interface technology is proposed and used, the previous communication system/air interface technology will not be replaced immediately. For example, after the 4G communication system is used, the 3G communication system and the 2G communication system are still in use, so In the current communication network, there are multiple communication systems coexisting. Among them, different communication systems use different communication technologies, for example, different communication systems, different frame structures, different modulation and demodulation technologies, different multiplexing technologies, and the like. However, all communication systems need to ensure the communication quality of the terminal equipment, that is, in any scenario, the terminal equipment must be able to access the service channel with the best channel quality at the location where the terminal equipment is located, in order to obtain high throughput and High spectral efficiency.

In order to ensure the communication quality of the terminal equipment, the terminal equipment needs to perform channel quality measurement on the current serving cell and the neighboring area, and track and synchronize the neighboring areas with good quality, so that the cell switching or reselection can be performed at any time. In the current scheme of tracking synchronization in some neighboring areas, when the terminal device is in the service state, because the terminal device is to send or receive data, the time resource is tight, and the time length allocated by the terminal device to the neighboring area synchronization task is limited. The neighboring area synchronization task may not be able to search for the synchronization signal sent by the neighboring area. It is necessary to perform multiple neighboring area synchronization tasks to search for the synchronization signal sent by the neighboring area. The terminal equipment needs a relatively long time to search for the neighboring area and The neighboring area is synchronized successfully. In the case of high-speed movement of the terminal device, the distance between the terminal device and the current serving cell is getting farther and farther. Because the location of the terminal device changes rapidly, the channel quality of the serving cell will also rapidly deteriorate, when the channel quality of the serving cell When the communication requirements of the terminal cannot be met, the terminal device needs to quickly switch to the neighboring cell with better channel quality, and the premise that the terminal device switches to the neighboring cell is that the terminal device has been synchronized with the neighboring cell, because the terminal device is in the service state. If the time required for synchronization with the neighboring cell is longer, the terminal device cannot switch to the neighboring cell in time. The channel quality of the serving cell changes continuously with time and the terminal cannot switch to the neighboring cell in time, which may result in The service of the terminal device is interrupted.

Summary of the invention

The present invention provides a resource scheduling method and a terminal device, which can be quickly synchronized with the neighboring cell to prevent the terminal device from being interrupted due to failure to access the neighboring cell in time.

In a first aspect, the embodiment of the present application provides a resource scheduling method, which is applied to a terminal device having a diversity receiving function, where the terminal device includes a main set antenna and a diversity antenna, and the method includes:

The terminal device acquires a scheduling task to be processed, and the terminal device is in a service state. If the scheduling task is a neighboring cell synchronization task, the terminal device performs the neighboring cell synchronization task by using the idle resource of the diversity antenna.

The terminal device in the service state refers to a terminal device that has established a communication channel with the network device in the serving cell and is performing data interaction with the network device, for example, in the LTE system, the terminal device with the RRC state being RRC-CONNECTED It is the terminal device in the business state.

In the present application, the terminal device performs the neighboring area synchronization task using the idle resources of the diversity antenna, since the diversity antenna is occupied only in the diversity reception and the secondary card paging, and the resources occupied by the diversity reception and the secondary card paging are only A very small part of the resources of the diversity antenna, the remaining resources can be allocated to the neighboring area synchronization task, so that the terminal equipment has sufficient resources to perform the neighboring area synchronization task, and when the resources are sufficient, the terminal equipment receives the neighboring area. The neighboring area has a greater probability of synchronizing signals, and can synchronize with the neighboring area more quickly, thereby quickly accessing the neighboring area and ensuring that the services of the terminal equipment are not interrupted.

With reference to the first aspect, in some embodiments, the idle resource of the diversity antenna may be the remaining resources of the resource of the diversity antenna except for the secondary card paging occupied resource, and the idle resource of the diversity antenna may also be the secondary card of the diversity antenna. The paging occupies resources and the remaining resources of the occupied resources that receive the serving cell data.

With reference to the first aspect, in some embodiments, the neighboring area synchronization task may be allocated resources according to the scenario or environment in which the terminal device is located, and the specific implementation manner includes, but is not limited to, the following two types:

First, the terminal device allocates resources to the neighboring area synchronization task according to the receiving mode in the current serving cell. When the receiving mode is the single antenna receiving mode, the terminal device allocates the idle resource of the diversity antenna to the neighboring area synchronization task. . In an optional implementation manner, in a case where the receiving mode is the dual antenna receiving mode, the terminal device may allocate resources to the neighboring area synchronization task according to the existing neighboring area synchronization task allocation scheme, or allocate the idle resources of the diversity antenna to the Neighbor synchronization tasks. The idle resources of the diversity antenna in the single antenna receiving mode can be applied to the initial neighboring area synchronization task and the periodic neighboring area synchronization task, and the idle resources of the diversity antenna in the dual antenna receiving mode can be applied to the periodic neighboring area synchronization task.

Second, the terminal device allocates resources to the neighboring area synchronization task according to the state of the terminal device. When the terminal device is in the location transition state, the terminal device allocates the idle resource of the diversity antenna to the neighboring area synchronization task; In the case of the location transfer state, the terminal device may allocate resources to the neighboring cells synchronously according to the existing neighboring area synchronization task allocation scheme. Wherein, when the terminal device is in the location transition state, it indicates that the terminal device may currently be in the motion scenario.

After the terminal device allocates resources to the neighboring area synchronization task, the terminal device can perform the neighboring area synchronization task by using the allocated resources.

In conjunction with the first aspect, in some embodiments, the terminal device can evaluate the status of the terminal device in accordance with the following manner:

In the first mode, the terminal device directly evaluates the state of the terminal device by using the moving speed of the terminal device. The terminal device determines the moving speed of the terminal device. When the moving speed is greater than the moving speed threshold, the terminal device determines that the terminal device is in the position shifting state.

In the second mode, the terminal device indirectly evaluates the state of the terminal device by using the signal strength reduction rate of the signal received by the terminal device from the current serving cell. The terminal device determines a signal strength weakening rate of the signal received from the current serving cell, and in a case where the signal strength weakening rate is greater than the weakening rate threshold, the terminal device determines that the terminal device is in the location transition state.

It should be noted that, not limited to the foregoing two evaluation methods, the terminal device may combine the motion speed of the terminal device, the acceleration of the terminal device, the signal strength of the serving cell, and the signal strength weakening rate of the serving cell, etc., by using the characteristics detected by the terminal device. Comprehensive evaluation of the status of the terminal device is not limited in this application.

With reference to the first aspect, in some embodiments, the terminal device may further determine a signal receiving state of the diversity antenna of the terminal device before performing the neighboring cell synchronization task using the idle resource of the diversity antenna, and determine a signal receiving state of the diversity antenna. In the case of a state, the terminal device performs the neighboring area synchronization task using the idle resources of the diversity antenna.

The signal receiving state of the diversity antenna of the terminal device is used to indicate whether the diversity antenna can work normally.

In conjunction with the first aspect, in some embodiments, the terminal device can determine the signal reception status of the diversity antenna of the terminal device in the following manner:

In a first mode, the terminal device acquires a first signal strength of a signal received by the diversity antenna of the terminal device from the target cell; if the first signal strength is greater than a signal strength threshold, the terminal device determines that the signal receiving state of the diversity antenna is First state.

In a second mode, the terminal device acquires a first signal strength of a signal received by the diversity antenna of the terminal device from the target cell; and the terminal device acquires a second signal strength of the signal received by the diversity antenna of the terminal device from the target cell; When the difference between the two signal strengths greater than the first signal strength is less than the signal strength difference threshold, the terminal device determines that the signal receiving state of the diversity antenna is the first state.

Here, the target cell is a cell detected by the terminal device in the process of the cell signal detection, and the target cell may be designed according to the actual situation, and the target cell may be the cell with the strongest signal strength detected by the terminal device in the cell signal detection process, and the target The cell may also be the current serving cell, or may be other preset cells, for example, a cell with the signal strength in the second place.

With reference to the first aspect, in some embodiments, the terminal device may allocate all idle resources of the diversity antenna to the neighboring area synchronization task; the terminal device may also allocate part of the idle resources of the diversity antenna as the target resource to the neighboring area synchronization. The task then performs the neighbor synchronization task using the target resource, and the terminal device determines the target resource as follows:

The terminal device determines a system attribute of a neighboring cell corresponding to the neighboring area synchronization task and a task attribute of the neighboring area synchronization task; the terminal device determines the target resource in the idle resource of the diversity antenna according to the system attribute and the task attribute.

In a possible implementation manner, in a case that the task attribute of the neighboring area synchronization task is the initial neighboring area synchronization task, the terminal device may determine the period of the synchronization signal sent by the neighboring area according to the system attribute of the neighboring area; the terminal device will divide the diversity. The first resource in the idle resource of the antenna is determined as the target resource, and the time length of the first resource is greater than or equal to the length of time of the cycle.

In another possible implementation manner, in a case that the task attribute of the neighboring area synchronization task is a periodic synchronization task, the terminal device may determine, according to the system attribute of the neighboring area, the resource occupied by the synchronization signal sent by the neighboring area; the terminal device The second resource in the idle resource of the diversity antenna is determined as the target resource, and the time length of the second resource is greater than or equal to the length of time of the resource occupied by the synchronization signal.

In a second aspect, the present application provides a terminal device having the function of implementing the method of the first aspect. The functions may be implemented by hardware or by corresponding software implemented by hardware. The hardware or software includes one or more units corresponding to the functions described above.

In a possible design, the terminal device comprises a processing unit, wherein the processing unit is configured to acquire a scheduling task to be processed, wherein the terminal device is in a service state; the processing unit is further configured to be in the scheduling In the case that the task is a neighboring area synchronization task, the neighboring area synchronization task is performed using the idle resources of the diversity antenna.

Detailed ways

The technical solutions in the embodiments of the present application will be described below with reference to the accompanying drawings in the embodiments of the present application.

FIG. 1 is a schematic structural diagram of a communication system according to an embodiment of the present application, where the communication system includes a terminal device and a network device. The terminal device and the network device communicate with each other through some air interface technology. In the communication system, a plurality of air interface technologies can coexist, and the air interface technology can include: existing 2G (such as GSM system), 3G (such as Universal Mobile Telecommunications System (UMTS), wideband code division) (Wideband Code Division Multiple Access (WCDMA), TD-SCDMA), 4G (such as FDD LTE, TDD LTE) and New RAT systems, such as 5G systems to be launched in the future.

The terminal device described in this application will be introduced in the general sense of the UE.

The network device described in the present application may be a device for communicating with the terminal device. Specifically, in the wireless communication system, the network device is a device that communicates with the terminal device in a wireless manner, for example, the network device may be A Base Transceiver Station (BTS) in a GSM or CDMA system, which may also be an NB (NodeB) in WCDMA, or an evolved Node B (eNB) in LTE, and a network in a future 5G network. A device or a network device in a future evolved PLMN network.

The cell (serving cell and neighboring cell) described in the present application refers to an area that can be covered by a network device that communicates with the terminal device, in which the terminal device can communicate with the network device in the cell by using a wireless signal. The serving cell refers to the area covered by the network device currently accessed by the terminal device; the neighboring cell refers to the area covered by the network device that is close to the network device currently accessed by the terminal device. In this application, a terminal device accessing a cell may be understood as a terminal device accessing a network device. The system attribute of the cell is related to the system to which the network device belongs. For example, if the network device belongs to the GSM system, the cell corresponding to the network device is a GSM cell.

Referring to FIG. 2, FIG. 2 is a schematic diagram of an application scenario provided by an embodiment of the present application. Figure 2 shows a serving cell and a cell adjacent thereto. As shown in FIG. 2, the serving cell is a cell currently accessed by the terminal device. In the vicinity of the serving cell, there are multiple cells whose coverage ranges partially overlap with each other, which is called a neighboring cell. In some cases, the terminal device is served. The cell switches to access these neighboring areas, and the terminal equipment needs to obtain downlink synchronization with these neighboring areas before switching to access these neighboring areas. In the neighboring cell of the serving cell, the central frequency of some of the neighboring cells is different from the central frequency of the serving cell, and these neighboring cells are referred to as neighboring cells that are different from the serving cell.

The downlink synchronization described in the present application refers to that the terminal device acquires a synchronization signal sent by the network device in the cell, and according to the synchronization signal, the terminal device can determine the clock signal of the network device, and further, in the case of the cell where the access network device is located. The terminal device uses the clock signal of the network device as a reference signal to perform timing adjustment on the content transmitted in the uplink and downlink channels to implement clock synchronization with the accessed cell.

The resource described in the present application refers to a time domain resource that the terminal device can use when performing a certain wireless communication task, where the time domain resource includes a length of time (ie, time) that the terminal device can occupy when performing the wireless communication task. Resources and hardware and software resources required to perform the wireless communication task in the length of time, wherein the hardware resources may include an antenna for performing the wireless communication task, a modem module corresponding to the antenna, and the like, and the software resources may include A computer program or the like that implements the wireless communication task, the time domain resource may further include a start time and a stop time of the time resource.

The solution of the present application is applicable to a cell in which the serving cell and the neighboring cell are inter-frequency. First, the situation of the serving cell and the neighboring cell, the neighboring zone synchronization task, and the resource allocation scheme of some neighboring zone synchronization tasks are introduced.

The serving cell and the neighboring cell can be divided into two categories: the serving cell and the neighboring cell of the same system, the serving cell of the different system, and the neighboring cell according to whether the system attributes are the same. Here, the system attribute refers to a wireless communication technology used by a network device in a cell to communicate with a terminal device.

In the first category, the serving cell and the neighboring cell are cells of the same system. In this category, the wireless communication technology used by the serving cell and the neighboring cell is the same. The serving cell and the neighboring cell may be in the following situations: the serving cell is a GSM system, the neighboring cell is a GSM system; the serving cell is a TD-SCDMA system, the neighboring cell is a TD-SCDMA system; the serving cell is a TDD-LTE system, and the neighboring cell For the TDD-LTE system.

In the second category, the serving cell and the neighboring cell are cells of different systems. In this category, the wireless communication technologies used by the serving cell and the neighboring cell are different. The serving cell and the neighboring cell may be in the following situations: the serving cell is a 2G system, the neighboring cell is any one of a 3G system, a 4G system, or a 5G system; the serving cell is a 3G system, and the neighboring cell is a 2G system or a 4G system. Or any one of the 5G systems; the serving cell is a 4G system, the neighboring cell is any one of a 2G system, a 3G system, or a 5G system; the serving cell is a 5G system, and the neighboring cell is a 2G system, a 3G system, or a 4G system. Any system in the system.

It should be noted that the serving cell and the neighboring cell of the same system and the serving cell and the neighboring cell of the different system are not limited to the above-mentioned cases, and the serving cell and the neighboring cell adopting the same wireless communication technology may be referred to as the same system. The serving cell and the neighboring cell, the serving cell and the neighboring cell adopting different wireless communication technologies may be referred to as the serving cell and the neighboring cell of the different system. For example, the serving cell is a TD-SCDMA system, and the neighboring area is a WCDMA system. Although both are 3G systems, the used wireless communication technologies are different, and the serving cell and the neighboring cell are different service cells and neighboring cells. Here, the wireless communication technology refers to a specification that must be observed in communication between various terminal devices such as a frame structure, a communication protocol, and a communication configuration and a network device in a cell.

The solution of the present application is applicable to the case where all the serving cells and the neighboring cells are cells of different frequencies. In the wireless communication system formed by the serving cell and the neighboring cell, the terminal device synchronizes with the serving cell clock, and the resource distribution of the terminal device is determined by the wireless communication technology used by the serving cell and the resources occupied by the terminal device to receive data and transmit data. . When the terminal device is in the service state, the terminal device performs the neighboring cell synchronization task on the premise of not colliding with the task of the serving cell to complete the synchronization with the neighboring cell.

In the present application, the terminal device in the service state refers to a terminal device in which the terminal device has established a communication channel with the network device in the serving cell, and the terminal device is performing uplink and downlink data transmission, for example, the terminal device is performing a call service, and the terminal device is performing a short message service. The terminal device is performing an upload task, the terminal device is performing a download task, and the like.

Neighbor synchronization tasks can be divided into initial neighbor synchronization tasks and periodic neighbor synchronization tasks according to task attributes. The initial neighboring area synchronization task refers to that the terminal device acquires the synchronization signal sent by the neighboring area by using the blind detection mode, and then synchronizes with the neighboring area according to the synchronization signal sent by the neighboring area. The periodic neighboring area synchronization task means that the terminal device has synchronized with the neighboring area at the first moment, and the terminal device can determine the period of the synchronization signal sent by the neighboring area according to the system attribute of the neighboring area, according to the period and the previous neighboring The first time at which the region obtains the synchronization determines the target time at which the synchronization signal is sent by the neighboring cell, wherein the target time is separated from the first time by the length of one or more cycles, and the terminal device acquires the neighboring region at the target time. The synchronization signal is synchronized with the neighboring area according to the synchronization signal sent by the neighboring area. In the initial neighboring area synchronization task, because the terminal device does not know when the synchronization signal is sent by the neighboring area, the terminal device may need to perform multiple blind detections to detect the synchronization signal sent by the neighboring area, and the required time resource is long.

In some resource allocation schemes for neighboring synchronization tasks, the terminal device allocates some fixed resources (fixed resources of the main set antenna, or fixed resources of the main set antenna and the diversity antenna) to the neighboring area synchronization task, and the terminal device can The neighboring area synchronization task is executed in the time period corresponding to the resource, and the synchronization signal sent by the neighboring area can be received at the time within the resources. For example, as shown in FIG. 3, in a resource allocation scheme in which the serving cell is a GSM system, the terminal device uses 26 radio frames as a period, in which resources of the idle frame are allocated to the neighboring area synchronization task, and the terminal equipment is in the idle frame. The neighboring area synchronization task is performed. According to the characteristics of the GSM system, the duration of one frame is 4.615 ms, that is, the time length of the time resource that can be allocated to the neighboring area synchronization task in one period is 4.615 ms; the serving cell is TD-SCDMA. In the resource allocation scheme of the system, the terminal device uses a radio subframe as a period, in which the resources of the idle time slot are allocated to the neighboring area synchronization task, and the terminal equipment performs the neighboring area synchronization task in the idle time slot, and the terminal device is in the terminal device. In the service state, the terminal device occupies at least 2 time slots to perform the task of the serving cell (ie, receiving data and transmitting data), and another time slot is a pilot time slot, and the terminal device can be in up to 4 idle time slots. The neighboring area synchronization task is performed. According to the characteristics of the TD-SCDMA system, the duration of one subframe is 5 ms, that is, the time resource that can be allocated to the neighboring area synchronization task in one cycle. The length is 2.7 ms. In the resource allocation scheme in which the serving cell is the LTE system, the terminal device allocates 6 ms measurement interval (GAP) resources to the neighboring area synchronization task in a 40 ms period, and the terminal device performs the neighboring area synchronization task at the measurement interval. ,and many more. It should be noted that the resource allocation scheme shown in FIG. 3 shows a resource allocation scheme of a primary set antenna and a diversity antenna of a terminal device. In a case where the terminal device is in a single antenna receiving mode, the terminal device may be in FIG. 3 . The resource allocated to the neighboring area synchronization task performs the neighboring area synchronization task through the primary set antenna; in the case that the terminal device is in the dual antenna receiving mode, the terminal device can pass the resource allocated to the neighboring area synchronization task shown in FIG. The main set antenna and the diversity antenna simultaneously perform the neighboring area synchronization task.

The resource allocation scheme using the neighboring area synchronization task described above takes a long time to perform the initial neighboring area synchronization task. Taking the neighboring area corresponding to the neighboring area synchronization task as the GSM system, the GSM system's cell sends 5 times of synchronization signals in the 0th frame, 10th frame, 20th frame, 30th frame, and 40th frame respectively. Here, the synchronization signal refers to a Frequency Correction Burst (FB) in the Frequency Correction Channel (FCCH), and the synchronization signal occupies 1 time slot. In the GSM system, there are 8 time slots in one frame, and synchronization is performed. The duration of the signal is 4.615ms/8=0.577ms. When the neighboring area sends the neighboring area synchronization signal to coincide with the time resource allocated by the terminal equipment for the neighboring area synchronization task, or when the terminal equipment is the time resource allocated by the neighboring area synchronization task, the terminal equipment can obtain the neighboring area. The synchronization signal then completes the neighbor synchronization.

It is assumed that the time at which the neighboring area synchronization signal is sent last time is the same as the time when the time resource of the last neighboring area synchronization task of the terminal device ends, and the terminal device starts timing at the time when the time resource of the last neighboring area synchronization task ends. The time required for the terminal device to perform the neighboring area synchronization task in the cell with different system attributes is as shown in FIG. 4a to FIG. 4c, and the unit of time in FIG. 4a-4c is ms. As shown in FIG. 4a, in the case that the serving cell is a GSM system, the terminal device performs a neighboring cell synchronization task in an idle frame, that is, the terminal device receives the synchronization signal of the neighboring cell in the idle frame, and the terminal device needs to blindly check 9 times for nearly 1080 ms. The time can obtain the complete synchronization signal sent by the neighboring cell; as shown in FIG. 4b, in the case that the serving cell is a TD-SCDMA system, the terminal device performs the neighboring area synchronization task in the idle time slot, that is, when the terminal device is idle The slot receives the synchronization signal of the neighboring area, and the terminal device needs to perform a blind detection 28 times for a total of 138.45 ms to obtain a complete synchronization signal sent by the neighboring cell; as shown in FIG. 4c, in the case that the serving cell is an LTE system, the terminal The device performs the neighboring area synchronization task at the measurement interval of 6 ms, that is, the terminal receives the synchronization signal of the neighboring area at the measurement interval of 6 ms, and the terminal device needs to perform blind detection for 6 times for a total of 235.365 ms to obtain the complete synchronization signal sent by the neighboring area. .

As can be seen from FIG. 4a to FIG. 4c, for the initial neighboring area synchronization task, the terminal device may not be able to acquire the synchronization signal sent by the neighboring area only by one blind detection in a limited time resource, and multiple blind detections are required to obtain the synchronization signal. The synchronization signal sent by the neighboring area is synchronized with the neighboring area, and the terminal equipment takes a long time to synchronize with the neighboring area. The resource allocation scheme of the neighboring area synchronization task cannot satisfy the synchronization of the terminal equipment in the high-speed motion process. time requirement. In addition, for the periodic neighbor synchronization task, the resources allocated to the neighbor synchronization task are less in the scheme shown in FIG. 3, and the resources for the periodic neighbor synchronization task are relatively less.

In the solution of the present application, the idle resources of the diversity antenna are allocated to the neighboring area synchronization task, and the resources of the diversity antenna are occupied only during the diversity reception and the secondary card paging, and other resources of the diversity antenna are idle resources, and the diversity is The idle resource of the antenna is more than the resources of the main set antenna, so that the terminal device can obtain the synchronization signal sent by the neighboring area through a small number of blind detection times, and can synchronize with the neighboring area in a short time, which is satisfied. The time requirement for the neighboring device to synchronize in the high-speed motion.

Next, some possible cases of the resource allocation scheme of the neighboring area synchronization task of the present application are introduced. The terminal device of the present application has a diversity receiving function.

(1) The terminal equipment is in the single antenna receiving mode in the serving cell.

In the single antenna receiving mode, the resources of the main set antenna are used to perform tasks in the serving cell (such as receiving data, transmitting data, etc.) and tasks that other terminal devices need to perform, and only use resources of the main set antenna when receiving data. Receive is performed without using the resources of the diversity antenna for reception. The resources of the diversity antenna of the terminal device are occupied only when the secondary card is paged. That is, in the single antenna receiving mode, the idle resource of the diversity antenna is the remaining resources of the resource of the diversity antenna except the secondary card paging resource. In the case that the terminal device is in the service state, the paging of the secondary card is periodic paging, and the paging cycle is generally about 5s. If the paging occupies one time slot, in the paging cycle of 5s, the paging occupies one. The resources of the time slot.

In the first possible scenario, all the idle resources of the diversity antenna may be allocated to the neighboring synchronization task, and the resources allocated to the neighboring synchronization task may be as shown in FIG. 5a, and the resources allocated to the neighboring synchronization task are the diversity. The resources of the antenna are removed from the resources occupied by the secondary card paging.

In the present application, the neighboring area periodically sends a synchronization signal, and the resources occupied by the synchronization signal sent by the neighboring area are fixed. The system attributes of the neighboring area are different, and the period of the synchronization signal sent by the neighboring area is different, and the neighboring area is different. The length of time that the generated sync signal occupies resources is also different. For example, in the GSM system, the cell transmits a synchronization signal at positions of 0th frame, 10 frames, 30 frames, and 40 frames in a period of 51 multiframes, and the resource occupied by the synchronization signal is a resource of one slot, the GSM system. In the TD-SCDMA system, the cell is sent in each subframe. The length of one frame is 4.615 ms, and the time of the resource occupied by the synchronization signal is 4.615 ms/8=57.7 μs. One synchronization signal, the resource occupied by the synchronization signal is the downlink pilot time slot (75 μs) resource, and the subframe length in the TD-SCDMA system is 5 ms, and the period of the synchronization signal sent by the TD-SCDMA cell is 5 ms; in the LTE system The synchronization signal is sent every 5 ms in the neighboring cell, and the resource occupied by the synchronization signal is a resource of Orthogonal Frequency Division Multiplexing (OFDM) symbol (about 71 μs).

It can be seen from the foregoing that the task attributes of the neighboring area synchronization task are different, and the resources required for performing the neighboring area synchronization task are different. It can be known from the foregoing that when the neighboring area sends the neighboring area synchronization signal, the time is exactly the same as that of the terminal equipment. When the allocated time resources are coincident or the time resources allocated by the terminal equipment for the neighboring area synchronization task, the terminal equipment can acquire the synchronization signal sent by the neighboring area, and the neighboring area periodically sends the synchronization signal, and the system attributes of the neighboring area are different. The period of the synchronization signal sent by the neighboring area is different, and the time length of the resources occupied by the synchronization signal sent by the neighboring area is also different. Therefore, the resources required to acquire the synchronization signal of the neighboring area are also different, so the system attributes of the neighboring area are different. The resources required to perform the neighbor synchronization task are different. In the second possible case, the idle resources of the diversity antenna may be allocated to the neighboring synchronization task according to the neighboring system attribute corresponding to the neighboring area synchronization task and the task attribute of the neighboring area synchronization task. In such an embodiment, the length of the idle resource allocated to the neighboring synchronization task is greater than or equal to the length of time required to perform the neighboring synchronization task.

In the case that the neighboring area synchronization task is a periodic neighboring area synchronization task, since the terminal device has previously obtained at least one synchronization with the neighboring area, the period of the synchronization signal sent by the neighboring area may be determined according to the system attribute of the neighboring area, according to The resources occupied by the synchronization signal sent by the neighboring area and the period of the neighboring area determine the resources allocated to the neighboring area synchronization task. The resource allocated to the periodic neighbor synchronization task can be as shown in FIG. 5b. In FIG. 5b, the resource occupied by the terminal device for the first time to obtain the synchronization signal sent by the neighboring cell is resource A, and the length of the resource A is equal to the complete neighbor. The time length of the resource required for the area synchronization signal, the period of the synchronization signal sent by the neighboring area is B1, and the resource C is the resource allocated to the periodic neighboring area synchronization task, wherein the time interval between the resource C and the resource C is B1. The time interval between the resource C and the resource A is nB1 (n is greater than or equal to 1), and the length of the resource C is greater than or equal to the length of time of the resource A.

In the case that the neighboring area synchronization task is the initial neighboring area synchronization task, the terminal device has not synchronized with the neighboring area, and the terminal device determines the period of the synchronization signal sent by the neighboring area according to the system attribute of the neighboring area, according to the neighboring area. The period in which the synchronization signal is issued determines the resources allocated to the neighboring synchronization task. The resource allocated to the neighboring area synchronization task may be as shown in FIG. 5c, the period in which the synchronization signal is sent by the neighboring area is B2, and the resource D is the target resource, where the starting time of the resource D is the time at which the neighboring area synchronization task is acquired. The length of time of resource D is greater than or equal to the length of time of B2.

(2) The terminal equipment is in the dual antenna receiving mode in the serving cell.

In the dual antenna receiving mode, the diversity antenna receives data when the primary antenna receives data, and the resources of the diversity antenna are occupied when receiving data and secondary card paging, that is, in the dual antenna receiving mode, the idle resources of the diversity antenna are The resources of the diversity antenna are excluded from the resources occupied by the received serving cell data and the secondary card paging, and the resources allocated to the neighboring synchronization task may be as shown in FIG. 5d, and the resources allocated to the neighboring synchronization task are the diversity antenna. The resource is excluded from the resource occupied by the secondary card paging and the resource after receiving the resource occupied by the serving cell data.

In this type of receiving mode, the idle resources of the diversity antenna can be allocated to the periodic neighboring area synchronization task. For the specific allocation, refer to the introduction of the single antenna receiving mode, and details are not described herein.

In this reception mode, resources can also be allocated to the periodic neighbor synchronization task according to the resource allocation scheme shown in FIG.

In a possible scenario, the terminal device may alternate between the single antenna receiving mode and the dual antenna receiving mode during the communication process. During the alternate process, the idle resources of the diversity antenna in the single antenna receiving mode may be preferentially allocated to The initial neighboring area synchronization task allocates idle resources of the diversity antenna in the dual antenna receiving mode to the periodic neighboring area synchronization task. Compared with the periodic neighbor synchronization task, the initial neighbor synchronization task takes a long time, while the diversity antenna of the diversity antenna in the single antenna reception mode has more idle resources than the diversity antenna in the dual antenna reception mode. When the idle resource is large, the task with a long time is executed, and when the idle resource is small, the task with a short time is executed, and the resource can be rationally utilized.

The foregoing describes some possible scenarios of the resource allocation scheme of the present application. Next, the method of the embodiment of the present application is introduced.

Referring to FIG. 6 , FIG. 6 is a schematic flowchart of a resource scheduling method according to an embodiment of the present disclosure. The method may be implemented on a terminal device that has a diversity receiving function, where the method includes:

Step S101: The terminal device acquires a scheduling task to be processed, where the terminal device is in a service state.

The terminal device in the service state has been introduced in the foregoing content, and details are not described herein again.

In the embodiment of the present application, the scheduled scheduling tasks include, but are not limited to, a neighboring area synchronization task, a neighboring area signal measurement task, a frequency point measurement task, a data transmission task, and a data receiving task.

In an implementation manner, the terminal device may acquire a scheduled scheduling task to be processed by using a frame interrupt processing program, where the frame interrupt processing program refers to a program that can process or allocate the scheduling task according to the priority of the scheduled task, and the frame interrupt processing program Prioritize or assign tasks with higher priority.

Step S102: If the scheduling task is a neighboring area synchronization task, the terminal device performs the neighboring area synchronization task by using an idle resource of the diversity antenna.

If the scheduled scheduling task is not the neighboring synchronization task, the terminal device allocates resources of the primary antenna to the scheduled scheduling task.

Here, there are two cases in which the scheduling task is a neighboring area synchronization task: 1) the verification period of the neighboring area synchronization task of the current arrival period needs to be resynchronized to the neighboring area, that is, the current scheduling task is a periodic neighboring area synchronization task; It is detected that a new neighboring cell is present, and the synchronization signal sent by the neighboring zone needs to be blindly detected, that is, the current scheduling task is the initial neighboring zone synchronization task.

In the first embodiment of the present application, the new neighboring cell may be defined as a neighboring zone that becomes a new N strong neighboring cell in the current neighboring cell signal measurement process, that is, the last neighboring cell signal measurement. In the process, the signal strength is not in the first N bits, and in the current neighboring cell signal measurement process, the signal strength becomes the first N bits of the cell, where N is a positive integer greater than or equal to 1, and N is the serving cell accessed by the terminal device. The system attribute determines, for example, that in the case where the serving cell is a GSM system, N is equal to 6; in the second possible implementation, the new neighboring cell may be defined as a signal strength less than neighboring in the previous neighboring cell signal measurement process. a cell synchronization threshold, and a cell whose signal strength is greater than a neighboring cell synchronization threshold in the current neighbor cell signal measurement process; in an optional implementation manner, the new neighbor cell may also be defined in combination with the above two cases, for example, a new The neighboring cell is defined as a cell that becomes a N strong neighboring cell and whose signal strength is greater than the neighboring cell synchronization threshold.

The following is an example of a new neighboring cell. The 802 system is located in the vicinity of the service neighboring cell. The current serving cell has 32 neighboring cells, numbered from 1 to 32. The signal is measured in the previous neighboring cell. In the process, the neighboring areas with the signal strength ranked in the first 6 positions include the neighboring areas numbered 1, 3, 10, 15, 20, 28, and the neighboring areas whose signal strength is greater than the synchronous threshold of the neighboring area include numbers 3, 10, and 15, Neighboring area of 28; in the neighboring area signal measurement process, the neighboring area with the signal strength ranked in the top 6 includes neighboring areas numbered 1, 3, 13, 15, 21, 28, and the signal strength is greater than the neighboring area synchronization threshold The neighborhood includes the neighbourhoods numbered 1, 3, 13, 28. If a new neighboring cell is determined according to the first possible implementation described above, the new neighboring cell is a neighboring cell numbered 13 and a neighboring cell numbered 21; if a new neighbor is determined according to the second possible implementation described above In the district, the new neighborhood is the adjacent area numbered 1 and the adjacent area numbered 13.

In the present application, the idle resource of the diversity antenna is used by the terminal device to perform the neighboring area synchronization task, that is, the terminal device allocates the idle resource of the diversity antenna to the neighboring area synchronization task.

In some possible implementation manners, the terminal device may allocate all idle resources of the diversity antenna to the neighboring area synchronization task, as shown in FIG. 5a or FIG. 5d, where the receiving mode of the terminal device in the serving cell is In the case of the single-antenna receiving mode (that is, only the data transmitted by the serving cell is received by the primary antenna), the resources allocated by the terminal device to the neighboring synchronization task are as shown in FIG. 5a, and the resources allocated by the terminal device to the neighboring synchronization task are diversity. The resource of the antenna is removed from the resource occupied by the secondary card paging; the receiving mode in the serving cell of the terminal device is a dual antenna receiving mode (ie, when receiving data transmitted by the serving cell, the primary set antenna and the diversity antenna are simultaneously used. In the case of receiving, the resource allocated by the terminal device to the neighboring area synchronization task is as shown in FIG. 5d, and the resource allocated by the terminal device to the neighboring area synchronization task is the resource of the diversity antenna, and the resource occupied by the secondary card paging and the receiving serving cell are removed. The resource after the resource is occupied by the resource.

In the present application, the system attribute of the serving cell has been introduced in the foregoing, wherein the system attribute of the serving cell and the service performed by the terminal device in the serving cell are different, the resources occupied by the secondary card paging and the resources occupied by the received data. It is different. For example, if the serving cell is a GSM system and the terminal device is performing a call service, the resource occupied by the secondary card paging is 1 time slot (ie, 0.577 ms), and the resource occupied by the received data is 1 time slot. In a specific implementation, the resource occupied by the secondary card paging and the resource occupied by the received data and the length of the resource may be determined according to the system attribute of the serving cell and the service performed by the terminal device, and then according to FIG. 5a or FIG. 5b. All idle resources of the diversity antenna are allocated to the neighboring area synchronization task, and the terminal equipment performs the neighboring area synchronization task using the resources allocated to the neighboring area synchronization task shown in FIG. 5a or shown in FIG. 5b.

In other possible implementations, some of the idle resources of the diversity antenna may be allocated to the neighbor synchronization task.

It can be seen from the foregoing that if the system attributes of the neighboring cells are different, the resources required for performing the neighboring area synchronization task are different, and the attributes of the neighboring area synchronization tasks are different, and the resources required for the initial neighboring area synchronization task and the periodic neighboring area synchronization task are performed. It is also different. The terminal device may determine a system attribute of a neighboring cell corresponding to the neighboring area synchronization task and a task attribute of the neighboring area synchronization task; determine, according to the system attribute and the task attribute, the target resource in the idle resource of the diversity antenna; and allocate the target resource to the neighboring area to synchronize task.

The target resource allocated by the terminal device to the neighboring area synchronization task according to the system attribute of the neighboring area and the task attribute of the neighboring area synchronization task may be specifically as shown in FIG. 5b and FIG. 5c. In the case that the neighboring cell synchronization task is a periodic neighboring cell synchronization task, the terminal device determines the resource occupied by the synchronization signal sent by the neighboring cell according to the system attribute of the neighboring cell; the terminal device determines the second resource in the idle resource of the diversity antenna as The target resource, the length of the second resource needs to be greater than or equal to the length of the resource occupied by the synchronization signal, and the target resource allocated to the neighboring synchronization task is as shown in FIG. 5b, where the resource C is the target resource, and the resource A is The time occupied by the synchronization signal sent by the neighboring cell, the length of the resource C is greater than or equal to the length of the resource A. The time interval between the resource C and the resource A is equal to nB1 (n is greater than or equal to 1), and B1 is the neighboring area. The period of the synchronization signal is sent; in the case that the neighboring area synchronization task is the initial neighboring area synchronization task, the terminal device determines the period of the synchronization signal sent by the neighboring area according to the system attribute of the neighboring area; the terminal device will be the first of the idle resources of the diversity antenna. A resource is determined as a target resource, and the length of the first resource needs to be greater than or equal to the length of the period in which the synchronization signal is sent by the neighboring cell, and is allocated to the neighboring area for synchronization. Service target resource as shown in FIG 5C, wherein D is a resource target resource, B2 to send a synchronization signal in the neighboring period, resources of time equal to the length D is greater than or B2. The length of time of resource C and resource D in Figures 5b and 5c is determined by the system properties of the neighboring cell. For example, in the case that the neighboring area is the GSM system, the length of the resource A is 0.577 ms, the length of the resource C is greater than or equal to 0.577 ms, and the period of the period in which the synchronization signal is sent by the neighboring area is 10 frames (46.15 ms, This refers to the length of 1 frame to 10 frames/11 frames to 20 frames/21 frames to 30 frames/31 frames to 40 frames in 51 multiframes) or 11 frames (50.765 ms, here refers to 41 in the previous 51 multiframes) The length of the resource D is greater than or equal to 11 frames from the frame to the length of the 0 frame in the current 51 multiframe.

In this application, after the target resource in the idle resource of the diversity antenna is allocated to the neighboring area synchronization task, the terminal device may perform the neighboring area synchronization task on the target resource, thereby implementing synchronization with the neighboring area. In the case that the neighboring area synchronization task is the initial neighboring area synchronization task, the time required for the terminal device to perform the neighboring area synchronization task after implementing the method of the present application is as shown in FIG. 7. The neighboring area corresponding to the neighboring area synchronization task is taken as the GSM system, and the serving cell is the GSM system. It is assumed that the neighboring area sends a synchronization signal to the resources of the neighboring area synchronization task once on the terminal equipment, and the terminal equipment is in the last neighbor. The resources of the area synchronization task are being synchronized with other neighboring cells. When the serving cell is the GSM system, the paging occupies resources of one time slot. As can be seen from FIG. 7, with the scheme of FIG. 5a and FIG. 5c of the present application, the terminal device can immediately perform the neighboring area synchronization task when the scheduling task is determined to be the neighboring area synchronization task, and the neighboring area can be acquired after 46.15 ms. The synchronization signal can be synchronized with the neighboring area more quickly, ensuring that the terminal equipment is not interrupted in the high-speed motion scene. In the case that the neighboring area synchronization task is a periodic neighboring area synchronization task, the idle antenna has more idle resources than the idle current resources of the primary set antenna, and the method of the present application can allocate more resources to the periodic neighboring area synchronization task.

In some embodiments, the terminal device may further determine a signal receiving state of the diversity antenna of the terminal device before performing the neighboring cell synchronization task using the idle resource of the diversity antenna, where the diversity antenna of the terminal device is in the first state, the terminal The device performs the neighbor synchronization task using the idle resources of the diversity antenna.

Here, the signal receiving state of the diversity antenna is used to indicate whether the diversity antenna can work normally, and in the case that the signal receiving state of the diversity antenna is the first state, the indicating diversity antenna can work normally.

In a possible implementation manner, when the diversity antenna can work normally, there is a certain requirement on the energy of the signal that the diversity antenna can receive, and it can be determined whether the signal energy received by the diversity antenna satisfies the set requirement. Determining a signal receiving state of the diversity antenna, the terminal device may obtain a first signal strength of the signal received by the diversity antenna from the target cell, and then compare the first signal strength with a signal strength threshold, where the first signal strength is greater than the signal strength threshold Next, it is determined that the signal receiving state of the diversity antenna is the first state. In a specific implementation, the terminal device may save the signal strength of each cell detected by the diversity antenna in the last cell signal detection process, and then obtain the first signal of the target cell detected by the diversity antenna from the saved signal strength of each cell. strength.

In another possible implementation manner, in the case that the diversity antenna can work normally, the energy difference between the received signal of the diversity antenna and the main set antenna from the same cell is required to be small, and the diversity antenna and the main set antenna can be determined. The energy difference of the received signal is used to determine a signal receiving state of the diversity antenna, and the terminal device may obtain a first signal strength of the signal received by the diversity antenna from the target cell, and obtain a second signal strength received by the primary antenna from the target cell, where When the difference between the second signal strength and the first signal strength is less than the signal strength difference threshold, it is determined that the signal receiving state of the diversity antenna is the first state. In a specific implementation, the terminal device may save the signal strength of each cell detected by the diversity antenna and the main set antenna in the last cell signal detection process, and then obtain the target detected by the diversity antenna from the saved signal strengths of the respective cells. The first signal strength of the cell and the second signal strength of the target cell detected by the primary set antenna.

In the embodiment of the present application, the target cell is any one of the cells detected by the terminal device in the cell signal detection process, and the target cell may be the cell with the strongest signal strength detected by the terminal device in the cell signal detection process, and the target cell. It may be a current serving cell, or may be another preset cell, for example, a cell with a signal strength in the second place, which is not limited in this application.

By judging the state of the diversity antenna, it is ensured that the diversity antenna can be used normally, so that the solution of the present application can be performed normally.

In some embodiments, whether to allocate resources to the neighboring synchronization task may be determined according to the scenario or environment in which the terminal is specifically located.

In a possible scenario, when the signal of the serving cell is good and the signal of the neighboring cell is poor, the terminal device adopts a single antenna receiving mode. To ensure that the neighboring area can be accessed at any time, the neighboring area needs to be frequently monitored, that is, In the case that the receiving mode of the terminal device in the current serving cell is the single antenna receiving mode, the terminal device allocates the target resource in the idle resource of the diversity antenna to the neighboring cell synchronization task according to the solution of the present application; When the signal of the neighboring area becomes better, the terminal device currently performs service in the serving cell, and the terminal device adopts the dual antenna receiving mode. Because the neighboring area signal is improved, the terminal device can detect the neighboring area more quickly, which can be reduced. For the frequency of the neighboring cell synchronization, the solution in the dual antenna receiving mode in the solution of the present application may be used, and the resource allocation scheme shown in FIG. 3 may also be used. The adjustment scheme of the neighboring area synchronization task is adjusted according to the receiving mode of the terminal device in the serving cell, so that the terminal device is more adapted to the change of the scenario and improves the synchronization performance of the terminal device.

In another possible scenario, the neighboring area synchronization task may be allocated resources according to the state of the terminal device, and in the case that the terminal device is in the location transition state, the solution of the present application is used to allocate resources to the neighboring area synchronization task, in the terminal device. In the case where the location transition state is not in place, the resource allocation scheme shown in FIG. 3 can be employed. When the terminal device is in the location transition state, it indicates that the terminal device may be in the motion scenario at present. In this case, the solution of the neighboring zone synchronization task is allocated by using the solution of the present application to ensure that the terminal device can quickly synchronize with the neighboring cell; In the location transfer state, the resource allocation scheme shown in FIG. 3 can meet the synchronization requirement of the terminal device. Since the resource allocation scheme shown in FIG. 3 has less time allocated to the neighboring area synchronization task, that is, the terminal device is reduced in execution. The time of the neighboring area synchronization task reduces the frequency of neighboring area synchronization and achieves the effect of power saving.

In a possible implementation manner, the motion speed of the terminal device may be used to directly evaluate the state of the terminal device, and if the motion speed is greater than the motion speed threshold, determine that the terminal device is in the location transition state; in another possible implementation In the mode, the signal strength weakening rate of the signal in the serving cell received by the terminal device may be used to indirectly evaluate the state of the terminal device, and if the signal strength weakening rate is greater than the weakening rate threshold, determining that the terminal device is in the location transition state; In other possible implementation manners, the characteristics of the motion condition of the terminal device detected by the terminal device, such as the motion speed of the terminal device, the acceleration of the terminal device, the signal strength of the serving cell, and the signal strength attenuation rate of the serving cell, may also be combined. To comprehensively evaluate the status of the terminal equipment.

After the implementation of the foregoing embodiment, the terminal can be better adapted to the change of the scenario or the environment, and meet the synchronization requirements of the terminal in different scenarios or environments. When the synchronization requirement of the terminal device is met, the time for performing the neighboring area synchronization task is reduced, the power consumption of the terminal device can be reduced, and the power saving effect can be achieved under the premise of ensuring the synchronization requirement of the terminal device.
