Description

Resource scheduling method and terminal equipment

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

With the development of communication technology, more and more communication systems are emerging, from 2G communication systems (such as Global System for Mobile Communications (GSM)) to 3G communication systems (such as Time Division-Synchronization Code Division Multiple Access (TD-SCDMA)) and from 3G communication systems to 4G communication systems (such as Long Term Evolution (LTE)) and even to 5G communication systems (such as New Radio (NR)) systems. When a new communication system/air interface technology is proposed and used, the previous communication system/air interface technology is not immediately replaced, for example, after a 4G communication system is used, a 3G communication system and a 2G communication system are still used, and thus, a plurality of communication systems coexist in the current communication network. Different communication systems employ different communication technologies, for example, different communication systems have different corresponding 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 device, that is, under any scenario, the terminal device is allowed to access the serving cell with the best channel quality at the location of the terminal device, so as to obtain high throughput and high spectral efficiency.

In order to ensure the communication quality of the terminal device, the terminal device needs to measure the channel quality of the current serving cell and the neighboring cell, and track and synchronize the neighboring cell with better quality, so as to perform cell switching or reselection at any time. In some current neighbor cell tracking synchronization schemes, when a terminal device is in a service state, time resources are short because the terminal device is required to send or receive data, the time length allocated to a neighbor cell synchronization task by the terminal device is limited, a synchronization signal issued by a neighbor cell may not be searched by one neighbor cell synchronization task, the synchronization signal issued by the neighbor cell may be searched by performing multiple neighbor cell synchronization tasks, and the terminal device may need a relatively long time to search for the neighbor cell and succeed in synchronization with the neighbor cell. Under the condition that the terminal equipment moves at a high speed, the distance between the terminal equipment and the current serving cell is more and more far, the channel quality of the serving cell is rapidly deteriorated along with the rapid change of the position of the terminal equipment, when the channel quality of the serving cell cannot meet the communication requirement of the terminal, the terminal equipment needs to be rapidly switched to a neighboring cell with better channel quality, and the terminal equipment is switched to the neighboring cell on the premise that the terminal equipment is synchronized with the neighboring cell, the terminal equipment cannot be timely switched to the neighboring cell due to the fact that the time required for the synchronization of the terminal equipment and the neighboring cell is longer in a service state, the channel quality of the serving cell is continuously deteriorated along with the change of time, the terminal cannot be timely switched to the neighboring cell, and the service interruption of the terminal equipment can be caused.

Disclosure of Invention

The resource scheduling method and the terminal device can be quickly synchronized with the adjacent cell, and service interruption caused by the fact that the terminal device cannot be accessed into the adjacent cell in time is avoided.

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

the terminal equipment acquires a scheduling task to be processed, and is in a service state; and under the condition that the scheduling task is a neighbor cell synchronization task, the terminal equipment uses the idle resources of the diversity antenna to execute the neighbor cell synchronization task.

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

In the application, the terminal device executes the adjacent region synchronization task by using the idle resource of the diversity antenna, because the diversity antenna is only occupied during diversity reception and auxiliary card paging, and the resource occupied by the diversity reception and the auxiliary card paging is only a very small part of the resource of the diversity antenna, the remaining resource can be distributed to the adjacent region synchronization task, so that the terminal device has sufficient resource to execute the adjacent region synchronization task, and under the condition of sufficient resource, the probability that the terminal device receives the adjacent region synchronization signal issued by the adjacent region is higher, and the adjacent region synchronization can be quickly synchronized with the adjacent region, thereby quickly accessing the adjacent region and ensuring that the service of the terminal device is not interrupted.

With reference to the first aspect, in some embodiments, the idle resource of the diversity antenna may be a remaining resource of the resources of the diversity antenna excluding the resource occupied by the secondary card paging, and the idle resource of the diversity antenna may also be a remaining resource of the resources of the diversity antenna excluding the resource occupied by the secondary card paging and the resource occupied for receiving the serving cell data.

With reference to the first aspect, in some embodiments, resources may be allocated to the neighbor cell synchronization task according to a scenario or an environment where the terminal device is located, and specific embodiments include, but are not limited to, the following two types:

first, a terminal device allocates resources to a neighbor synchronization task according to a receiving mode in a current serving cell, and under the condition that the receiving mode is a single-antenna receiving mode, the terminal device allocates idle resources of a diversity antenna to the neighbor synchronization task. In an optional embodiment, when the receiving mode is the dual-antenna receiving mode, the terminal device may allocate resources to the neighboring cell synchronization task according to an existing neighboring cell synchronization task allocation scheme, and may also allocate idle resources of the diversity antenna to the neighboring cell synchronization task. The idle resources of the diversity antenna in the single-antenna receiving mode can be suitable for an initial neighbor synchronization task and a periodic neighbor synchronization task, and the idle resources of the diversity antenna in the dual-antenna receiving mode can be suitable for the periodic neighbor synchronization task.

Secondly, the terminal equipment allocates resources to the adjacent region synchronization task according to the state of the terminal equipment, and under the condition that the terminal equipment is in a position transfer state, the terminal equipment allocates idle resources of the diversity antenna to the adjacent region synchronization task; under the condition that the terminal equipment is not in the position transfer state, the terminal equipment can synchronously distribute resources to the adjacent cells according to the existing adjacent cell synchronous task distribution scheme. When the terminal device is in the position transition state, it indicates that the terminal device may be currently in a motion scene.

After the terminal equipment allocates the resources to the neighbor cell synchronization task, the terminal equipment can execute the neighbor cell synchronization task by using the allocated resources.

In combination with the first aspect, in some embodiments, the terminal device may evaluate the state of the terminal device according to the following:

in the first mode, the terminal device directly evaluates the state of the terminal device using the movement speed of the terminal device. The terminal device determines the movement speed of the terminal device, and under the condition that the movement speed is larger than the movement speed threshold value, the terminal device determines that the terminal device is in a position transfer 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 reduction rate of a signal received from a current serving cell, and determines that the terminal device is in a position transition state when the signal strength reduction rate is greater than a reduction rate threshold.

It should be noted that, without being limited to the above two evaluation manners, the terminal device may comprehensively evaluate the state of the terminal device by combining the characteristics 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 reduction rate of the serving cell, and the application is not limited in this application.

With reference to the first aspect, in some embodiments, before the terminal device performs the neighboring cell synchronization task using the idle resource of the diversity antenna, the terminal device may further determine a signal reception state of the diversity antenna of the terminal device, and when it is determined that the signal reception state of the diversity antenna is the first state, the terminal device performs the neighboring cell synchronization task using the idle resource of the diversity antenna.

The signal receiving state of the diversity antenna of the terminal equipment is used for indicating whether the diversity antenna can work normally or not.

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

in a first mode, terminal equipment acquires a first signal strength of a signal received by a diversity antenna of the terminal equipment from a target cell; and under the condition that the first signal strength is greater than the signal strength threshold, the terminal equipment determines the signal receiving state of the diversity antenna to be a first state.

In a second mode, the terminal device obtains a first signal strength of a signal received by a diversity antenna of the terminal device from a target cell; the terminal equipment acquires a second signal strength of a signal received by a diversity antenna of the terminal equipment from the target cell; and under the condition that the difference value of the second signal strength which is greater than the first signal strength is less than the signal strength difference threshold, the terminal equipment determines the signal receiving state of the diversity antenna to be the first state.

Here, the target cell is a cell detected by the terminal device in the cell signal detection process, and the target cell may be designed according to actual conditions, and the target cell may be a cell with the strongest signal strength detected by the terminal device in the cell signal detection process, may also be a current serving cell, and may also be another preset cell, for example, a cell with the second signal strength.

With reference to the first aspect, in some embodiments, the terminal device may allocate all idle resources of the diversity antenna to the neighbor synchronization task; the terminal device may also allocate a part of resources in the idle resources of the diversity antenna as target resources to the neighboring cell synchronization task, and then execute the neighboring cell synchronization task using the target resources, where the method for the terminal device to determine the target resources is as follows:

the terminal equipment determines the system attribute of the adjacent cell corresponding to the adjacent cell synchronous task and the task attribute of the adjacent cell synchronous task; and the terminal equipment determines a target resource in idle resources of the diversity antenna according to the system attribute and the task attribute.

In a possible implementation manner, under the condition that the task attribute of the neighbor synchronization task is the initial neighbor synchronization task, the terminal device can determine the cycle of sending the synchronization signal by the neighbor according to the system attribute of the neighbor; and the terminal equipment determines a first resource in the idle resources of the diversity antenna as a target resource, wherein the time length of the first resource is greater than or equal to the time length of the period.

In another possible implementation manner, under the condition that the task attribute of the synchronization task of the neighboring cell is a periodic synchronization task, the terminal device may determine, according to the system attribute of the neighboring cell, a resource occupied by a synchronization signal issued by the neighboring cell; and the terminal equipment determines a second resource in the idle resources of the diversity antenna as a target resource, wherein the time length of the second resource is greater than or equal to the time length of the resource occupied by the synchronization signal.

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

In one possible design, the terminal device includes a processing unit, where the processing unit is configured to obtain a scheduling task to be processed, where the terminal device is in a service state; and the processing unit is also used for executing the adjacent region synchronization task by using the idle resource of the diversity antenna under the condition that the scheduling task is the adjacent region synchronization task.

In one possible design, the terminal device includes a processor, a memory, and a transceiver, the processor, the memory, and the transceiver being interconnected, wherein the transceiver includes a main set antenna and a diversity antenna, the memory is configured to store program code, and the processor is configured to invoke the program code to perform the following operations: acquiring a scheduling task to be processed, wherein the terminal equipment is in a service state; and under the condition that the scheduling task is a neighbor cell synchronization task, executing the neighbor cell synchronization task by using idle resources of the diversity antenna through the diversity antenna.

Detailed Description

The technical solutions in the embodiments of the present application will be described below with reference to the 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. Wherein the terminal device and the network device communicate with each other through some air interface technology. In the communication system, multiple air interface technologies may coexist, and the air interface technologies may include: existing 2G (e.g., GSM System), 3G (e.g., Universal Mobile Telecommunications System (UMTS), Wideband Code Division Multiple Access (WCDMA), TD-SCDMA), 4G (e.g., FDD LTE, TDD LTE), and New RAT systems, such as the 5G System that will be introduced into the market in the future.

The terminal equipment described in this application will be introduced in a general sense as UE. Further, a terminal device can also be called a user device, mobile station, access terminal, subscriber unit, subscriber station, mobile station, remote terminal, mobile device, user terminal, wireless communication device, user agent, or user equipment, among others. The user equipment may be a cellular phone, a cordless phone, a Session Initiation Protocol (SIP) phone, a Wireless Local Loop (WLL) station, a Personal Digital Assistant (PDA), a handheld device with Wireless communication capability, a computing device or other processing device connected to a Wireless modem, a vehicle mounted device, a wearable device, a Mobile station in a future 5G Network or a terminal device in a future evolved Public Land Mobile Network (PLMN) Network, etc.

The network device described in this application may be a device for communicating with a terminal device, and in particular, in a 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, an nb (nodeb) in a WCDMA system, an evolved Node B (eNB) in an LTE system, a network device in a future 5G network or a network device in a future evolved PLMN network, and the like.

The cells (serving cell and neighboring cell) described in this application refer to an area that can be covered by a network device communicating with a terminal device, and in this area, the terminal device can communicate with the network device in the cell through a wireless signal. The service cell refers to an area covered by network equipment which is currently accessed by the terminal equipment; the neighboring cell refers to an area covered by a network device close to the network device to which the terminal device is currently connected. In this application, the terminal device accessing the cell may be understood as the terminal device accessing the 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 a 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 in an embodiment of the present application. Fig. 2 shows a serving cell and cells adjacent thereto. As shown in fig. 2, a serving cell is a cell to which a terminal device is currently accessed, and in the vicinity of the serving cell, there are a plurality of cells whose coverage areas partially overlap with the serving cell, which are called as neighboring cells. In the neighboring cells of the serving cell, the center frequency point of some neighboring cells is different from the center frequency point of the serving cell, and these neighboring cells are called as neighboring cells having different frequencies from the serving cell.

The downlink synchronization described in the present application refers to that the terminal device obtains a synchronization signal issued by the network device in the cell, and according to the synchronization signal, the terminal device can determine a clock signal of the network device, and then, when the network device is accessed to the cell, 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, so as to implement clock synchronization with the accessed cell.

The resource described in this application refers to a time domain resource that can be used by a terminal device when executing a certain wireless communication task, where the time domain resource includes a time length (i.e., a time resource) that can be occupied by the terminal device when executing the wireless communication task and hardware and software resources that need to be used when executing the wireless communication task in the time length, where the hardware resource may include an antenna for executing the wireless communication task and a modem module corresponding to the antenna, the software resource may include a computer program for implementing the wireless communication task, and the time domain resource may also include a start time and an end time of the time resource.

The scheme of the application is suitable for the cells with different frequencies of the serving cell and the adjacent cell. Firstly, the conditions of a service cell and a neighboring cell, neighboring cell synchronization tasks and resource allocation schemes of some neighboring cell synchronization tasks are introduced.

The service cell and the adjacent cell can be divided into two categories, namely the service cell and the adjacent cell of the same system and the service cell and the adjacent cell of a different system according to whether the system attributes are the same or not. Here, the system attribute refers to a wireless communication technique employed by the network device in the cell to communicate with the 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 technologies employed by the serving cell and the neighboring cell are the same. The serving cell and the neighboring cell may be the following: the service cell is a GSM system, and the adjacent cell is the GSM system; the service cell is a TD-SCDMA system, and the adjacent cell is the TD-SCDMA system; the service cell is a TDD-LTE system, and the adjacent cell is 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 employed by the serving cell and the neighboring cell are different. The serving cell and the neighboring cell may be the following: the service cell is a 2G system, and the adjacent cell is any one of a 3G system, a 4G system or a 5G system; the service cell is a 3G system, and the adjacent cell is any one of a 2G system, a 4G system or a 5G system; the service cell is a 4G system, and the adjacent cell is any one of a 2G system, a 3G system or a 5G system; the service cell is a 5G system, and the adjacent cell is any one of a 2G system, a 3G system or a 4G 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 serving cell and the neighboring cell of the same system, and the serving cell and the neighboring cell adopting the different wireless communication technology 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, the neighboring cell is a WCDMA system, although both are 3G systems, but the adopted wireless communication technologies are different, the serving cell and the neighboring cell are heterogeneous serving cells and neighboring cells. Here, the radio communication technology is a specification to which various terminal devices and network devices in a cell must comply with in order to communicate with each other, such as a frame structure, a communication protocol, and a communication configuration.

The scheme of the application is suitable for the situation that all the service cells and the adjacent cells are the cells with different frequencies. In a wireless communication system formed by a service cell and an adjacent cell, a terminal device and the service cell are synchronized in time, and the resource distribution condition of the terminal device is determined by the wireless communication technology adopted by the service cell and the resources occupied by the terminal device for receiving and sending data. Under the condition that the terminal equipment is in a service state, the terminal equipment executes the adjacent cell synchronization task on the premise of ensuring that the task of the terminal equipment does not conflict with the task of the service cell so as to complete the synchronization with the adjacent cell.

In this application, a terminal device in a service state refers to a terminal device that has established a communication channel with a network device in a serving cell and is performing uplink and downlink data transmission, for example, the terminal device is performing a call service, 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.

The adjacent region synchronization task can be divided into an initial adjacent region synchronization task and a periodic adjacent region synchronization task according to task attributes. The initial neighbor synchronization task means that the terminal equipment acquires a synchronization signal issued by a neighbor in a blind detection mode under the condition that the terminal equipment is not synchronized with the neighbor yet, and then is synchronized with the neighbor according to the synchronization signal issued by the neighbor; the periodic neighbor synchronization task means that the terminal device is synchronized with a neighbor at a previous first time, the terminal device can determine a period for sending a synchronization signal by the neighbor according to the system attribute of the neighbor, and determine a target time for sending the synchronization signal by the neighbor according to the period and the previous first time for synchronizing with the neighbor, wherein the target time is separated from the first time by one or more periods, and the terminal device obtains the synchronization signal sent by the neighbor at the target time and synchronizes with the neighbor according to the synchronization signal sent by the neighbor. In the initial neighbor synchronization task, since the terminal device does not know when the neighbor specifically issues the synchronization signal, the terminal device may need to perform multiple blind detections to detect the synchronization signal issued by the neighbor, and the required time resource is long.

In some resource allocation schemes for neighbor synchronization tasks, terminal equipment allocates some fixed resources (fixed resources of a primary set antenna, or fixed resources of a primary set antenna and a diversity antenna) to the neighbor synchronization tasks, and the terminal equipment can execute the neighbor synchronization tasks in time periods corresponding to the resources, that is, can receive synchronization signals issued by a neighbor at times in the resources. For example, as shown in fig. 3, in a resource allocation scheme in which a serving cell is a GSM system, a terminal device uses 26 wireless frames as a period, and allocates resources of an idle frame to a neighbor synchronization task in the period, and the terminal device executes the neighbor synchronization task in the idle frame, where as can be known from characteristics of the GSM system, a time length of one frame is 4.615ms, that is, a time length of time resources that can be allocated to the neighbor synchronization task in one period is 4.615 ms; in the resource allocation scheme that the serving cell is a TD-SCDMA system, the terminal device takes 1 wireless subframe as a period, the resource of an idle time slot is allocated to a neighbor cell synchronization task in the period, the terminal device executes the neighbor cell synchronization task in the idle time slot, when the terminal device is in a service state, the terminal device at least occupies 2 time slots to execute the task of the serving cell (namely, receiving data and sending data), in addition, one time slot is a pilot time slot, the terminal device can execute the neighbor cell synchronization task in 4 idle time slots at most, the characteristic of the TD-SCDMA system can be known, the time length of one subframe is 5ms, namely, the time length of the time resource which can be allocated to the neighbor cell synchronization task in one period is 2.7 ms; in a resource allocation scheme in which a serving cell is an LTE system, a terminal device allocates resources of a measurement GAP (GAP) of 6ms to a neighbor synchronization task in a period of 40ms, and executes the neighbor synchronization task in the measurement GAP, and so on. It should be noted that the resource allocation scheme shown in fig. 3 is a resource allocation scheme of a main set antenna and a diversity antenna of a terminal device, and when the terminal device is in a single antenna receiving mode, the terminal device may execute a neighbor cell synchronization task through the main set antenna on the resource allocated to the neighbor cell synchronization task shown in fig. 3; under the condition that the terminal device is in the dual-antenna receiving mode, the terminal device may simultaneously execute the neighbor synchronization task through the main set antenna and the diversity antenna on the resource allocated to the neighbor synchronization task shown in fig. 3.

The resource allocation scheme of the adjacent cell synchronization task needs longer time when the initial adjacent cell synchronization task is executed. Taking the neighboring cell corresponding to the neighboring cell synchronization task as an example of a GSM system, a cell of the GSM system respectively issues 5 times of synchronization signals (here, a synchronization signal refers to a Frequency Correction Burst (FB) in a Frequency Correction Channel (FCCH)) in a frame 0, a frame 10, a frame 20, a frame 30, and a frame 40 with a frame 51 as a cycle), the synchronization signals occupy 1 time slot, one frame in the GSM system has 8 time slots, and the duration of the synchronization signals is 4.615ms/8 — 0.577 ms. When the time for sending the synchronization signal of the neighboring cell by the neighboring cell is just coincident with the time resource allocated by the terminal device for the synchronization task of the neighboring cell or in the time resource allocated by the terminal device for the synchronization task of the neighboring cell, the terminal device can obtain the synchronization signal sent by the neighboring cell to complete the synchronization of the neighboring cell.

Assuming that the time when the last sending of the neighbor synchronization signal by the neighbor ends is exactly the same as the time when the last time of the neighbor synchronization task by the terminal device ends, the terminal device starts to time at the time when the last time of the neighbor synchronization task by the terminal device ends, the time required by the terminal device to execute the neighbor synchronization task in the cells with different system attributes is shown in fig. 4a-4c, and the unit of the time in fig. 4a-4c is ms. As shown in fig. 4a, in a case that a serving cell is a GSM system, a terminal device executes a synchronization task of a neighboring cell in an idle frame, that is, the terminal device receives a synchronization signal of the neighboring cell in the idle frame, and the terminal device needs to perform blind detection for 9 times of approximately 1080ms to obtain a complete synchronization signal issued 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 a synchronization task of the neighboring cell in the idle time slot, that is, the terminal device receives a synchronization signal of the neighboring cell in the idle time slot, and the terminal device needs to perform blind detection 28 times for 138.45ms in total to obtain a complete synchronization signal delivered by the neighboring cell; as shown in fig. 4c, in the case that the serving cell is an LTE system, the terminal device executes a neighbor cell synchronization task at a measurement interval of 6ms, that is, the terminal device receives a synchronization signal of a neighbor cell at the measurement interval of 6ms, and the terminal device needs to perform blind detection 6 times for 235.365ms in total to obtain a complete synchronization signal delivered by the neighbor cell.

As can be seen from fig. 4a to 4c, for the initial neighbor synchronization task, in a limited time resource, the terminal device may not obtain the synchronization signal delivered by the neighbor through one-time blind detection, and needs to perform multiple blind detections to obtain the synchronization signal delivered by the neighbor so as to synchronize with the neighbor, the terminal device needs a longer time to synchronize with the neighbor, and the resource allocation scheme of the neighbor synchronization task cannot meet the time requirement of the terminal device on neighbor synchronization in a high-speed motion process. In addition, for the periodic neighbor synchronization task, the solution shown in fig. 3 has fewer resources allocated to the neighbor synchronization task, and the resources used for the periodic neighbor synchronization task are also relatively fewer.

In the scheme of the application, the idle resources of the diversity antenna are allocated to the synchronization task of the adjacent cell, because the resources of the diversity antenna are occupied only during diversity reception and paging of the auxiliary card, other resources of the diversity antenna are idle resources, and the idle resources of the diversity antenna are more than those of the main set antenna, the terminal equipment can acquire the synchronization signal issued by the adjacent cell through fewer blind detection times, can be synchronized with the adjacent cell within a shorter time, and meets the time requirement of the terminal equipment on synchronization of the adjacent cell in the high-speed movement process.

Next, some possible situations of the resource allocation scheme of the neighboring cell synchronization task according to the present application are introduced, and the terminal device according to the present application has a diversity reception function.

Terminal equipment is in single antenna receiving mode in service cell

In the single antenna receiving mode, the resources of the main set antenna are used for normally performing tasks (such as receiving data, transmitting data, and the like) in the serving cell and other tasks that the terminal device needs to perform, and only the resources of the main set antenna are used for receiving when receiving data, and the resources of the diversity antenna are not used for receiving. The resources of the diversity antenna of the terminal equipment are occupied only when the secondary card pages, namely, in the single antenna receiving mode, the idle resources of the diversity antenna are the residual resources except the resources occupied by the secondary card paging in the resources of the diversity antenna. Under the condition that the terminal equipment is in a service state, paging of the secondary card is periodic paging, the paging period is about 5s generally, and if the paging occupies one time slot, the paging occupies the resource of the time slot in the paging period of 5 s.

In a first possible case, all idle resources of the diversity antenna may be allocated to the neighboring cell synchronization task, the resource allocated to the neighboring cell synchronization task may be as shown in fig. 5a, and the resource allocated to the neighboring cell synchronization task is a resource after a resource occupied by the secondary card paging is removed from the resource of the diversity antenna.

In the method, the adjacent cells periodically send the synchronization signals underground, and resources occupied by the synchronization signals sent by the adjacent cells are fixed, wherein the system attributes of the adjacent cells are different, the periods of the synchronization signals sent by the adjacent cells are different, and the time lengths of the resources occupied by the synchronization signals sent by the adjacent cells are also different. For example, in a GSM system, a cell issues a synchronization signal at the positions of frames 0, 10, 30, and 40 respectively with a cycle of 51 multiframes, the resource occupied by the synchronization signal is a resource of 1 timeslot, in the GSM system, the length of one frame is 4.615ms, and the length of one frame is 8 timeslots, so the time length of the resource occupied by the synchronization signal is 4.615ms/8 ═ 57.7 μ s; in the TD-SCDMA system, a cell transmits a synchronous signal once in each subframe, the resource occupied by the synchronous signal is the resource of a downlink pilot frequency time slot (75 mus), the subframe length in the TD-SCDMA system is 5ms, and the period of transmitting the synchronous signal by the cell of the TD-SCDMA is 5 ms; in the LTE system, a neighboring cell issues a synchronization signal every 5ms, and a resource occupied by the synchronization signal is a resource of an Orthogonal Frequency Division Multiplexing (OFDM) symbol (about 71 μ s).

According to the above contents, the task attributes of the neighboring cell synchronization tasks are different, and the resources required for executing the neighboring cell synchronization tasks are different; as can be seen from the foregoing, when the time for sending the synchronization signal of the neighboring cell by the neighboring cell is exactly coincident with the time resource allocated by the terminal device for the synchronization task of the neighboring cell, or is in the time resource allocated by the terminal device for the synchronization task of the neighboring cell, the terminal device may obtain the synchronization signal sent by the neighboring cell, and the neighboring cell periodically sends the synchronization signal underground, the system attributes of the neighboring cells are different, the periods for sending the synchronization signal by the neighboring cell are different, and the time lengths of the resources occupied by the synchronization signal sent by the neighboring cell are also different, so the resources required for obtaining the synchronization signal of the neighboring cell are also different, and therefore the system attributes of the neighboring cells are different, and the resources required for executing the synchronization task of the neighboring cell are different. In a second possible case, idle resources of the diversity antenna may be allocated to the neighbor synchronization task according to a neighbor system attribute corresponding to the neighbor synchronization task and a task attribute of the neighbor synchronization task. In such an embodiment, the length of time of the idle resources allocated to the neighbor synchronization task is greater than or equal to the length of time of the resources required to execute the neighbor synchronization task.

When the adjacent cell synchronization task is a periodic adjacent cell synchronization task, because the terminal device has obtained at least one synchronization with the adjacent cell before, the period of sending the synchronization signal by the adjacent cell can be determined according to the system attribute of the adjacent cell, and the resource allocated to the adjacent cell synchronization task is determined according to the resource occupied by the synchronization signal sent by the adjacent cell and the period of the adjacent cell. The resource allocated to the periodic neighbor synchronization task may be as shown in fig. 5B, a resource occupied by the terminal device for obtaining the synchronization signal issued by the neighbor for the first time is resource a, a time length of resource a is equal to a time length of a resource required for obtaining the complete neighbor synchronization signal, a period of issuing the synchronization signal by the neighbor is B1, and resource C is a resource allocated to the periodic neighbor synchronization task, where a time interval between resource C and resource C is B1, a time interval between resource C and resource a is nB1(n is greater than or equal to 1), and a time length of resource C is greater than or equal to a time length of resource a.

And under the condition that the adjacent cell synchronization task is the initial adjacent cell synchronization task, the terminal equipment is not synchronized with the adjacent cell, the terminal equipment determines the period of sending the synchronization signal by the adjacent cell according to the system attribute of the adjacent cell, and can determine the resource allocated to the adjacent cell synchronization task according to the period of sending the synchronization signal by the adjacent cell. The resource allocated to the synchronization task of the neighboring cell may be as shown in fig. 5c, where a cycle of sending the synchronization signal by the neighboring cell is B2, and the resource D is a target resource, where a starting time of the resource D is a time when the synchronization task of the neighboring cell is acquired, and a time length of the resource D is greater than or equal to a time length of B2.

(II) the terminal equipment is in a dual-antenna receiving mode in the service cell

In the dual-antenna receiving mode, the diversity antenna receives data when the main set antenna receives data, resources of the diversity antenna are occupied when receiving data and paging of the secondary card, namely in the dual-antenna receiving mode, idle resources of the diversity antenna are residual resources except for resources occupied by receiving service cell data and paging of the secondary card in the resources of the diversity antenna, resources allocated to a synchronization task of a neighboring cell can be shown as 5d, and resources allocated to the synchronization task of the neighboring cell are resources except for resources occupied by paging of the secondary card and resources occupied by receiving service cell data in the resources of the diversity antenna.

In this receiving mode, the idle resources of the diversity antenna may be allocated to the periodic neighbor synchronization task, and the specific allocation situation may refer to the description of the single antenna receiving mode, which is not described herein again.

In this receiving mode, resources may also be allocated to the periodic neighbor synchronization task according to the resource allocation scheme shown in fig. 3.

In a possible scenario, the terminal device may perform the single antenna receiving mode and the dual antenna receiving mode alternately in the communication process, and in the alternate performing process, the idle resources of the diversity antenna in the single antenna receiving mode may be preferentially allocated to the initial neighbor synchronization task, and the idle resources of the diversity antenna in the dual antenna receiving mode may be allocated to the periodic neighbor synchronization task. Compared with the periodic neighbor synchronization task, the time required for the initial neighbor synchronization task is longer, idle resources of the diversity antenna in the single-antenna receiving mode are more than idle resources of the diversity antenna in the dual-antenna receiving mode, the task with longer execution time is performed when the idle resources are more, the task with shorter execution time is performed when the idle resources are less, and the reasonable utilization of the resources can be realized.

The foregoing describes some possible scenarios of the resource allocation scheme of the present application, and the method of the embodiments of the present application is described next.

Referring to fig. 6, fig. 6 is a schematic flowchart of a resource scheduling method provided in an embodiment of the present application, where the method may be implemented on a terminal device with a diversity reception function, and the method includes:

step S101, the terminal device obtains a scheduling task to be processed, wherein the terminal device is in a service state.

The terminal device in the service state is introduced in the foregoing content, and is not described herein again.

In the embodiment of the application, the scheduling tasks to be processed include, but are not limited to, a neighbor synchronization task, a neighbor signal measurement task, a frequency point measurement task, a data transmission task, and a data reception task.

In one implementation, the terminal device may obtain the scheduling task to be processed through a frame interrupt handler, where the frame interrupt handler refers to a program that can process or allocate the scheduling task according to the priority of the scheduling task, and the frame interrupt handler preferentially processes or allocates a task with a high priority.

Step S102, under the condition that the scheduling task is a neighbor cell synchronization task, the terminal equipment uses idle resources of the diversity antenna to execute the neighbor cell synchronization task.

And under the condition that the scheduling task to be processed is not a neighbor cell synchronous task, the terminal equipment allocates the resources of the main set antenna to the scheduling task to be processed.

Here, there are two cases when the scheduling task is a neighbor synchronization task: 1) when the verification period of the current arrival period adjacent cell synchronization task is reached, the adjacent cells need to be resynchronized, namely the current scheduling task is a period adjacent cell synchronization task; 2) when a new neighbor cell is detected to appear, a synchronization signal issued by the neighbor cell needs to be detected in a blind manner, namely, the current scheduling task is an initial neighbor cell synchronization task.

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

Taking the serving neighbor cell where the terminal device is currently located as a GSM system as an example, 32 neighbor cells are located near the current serving cell, and the numbers are 1 to 32, respectively, in the last neighbor cell signal measurement process, the neighbor cells with the signal strength ranked at the first 6 include the neighbor cells with the numbers of 1, 3, 10, 15, 20, and 28, and the neighbor cells with the signal strength greater than the neighbor cell synchronization threshold include the neighbor cells with the numbers of 3, 10, 15, and 28; in the process of measuring the signal of the neighboring cells at this time, the neighboring cells with the signal strength ranked at the first 6 include the neighboring cells with the numbers of 1, 3, 13, 15, 21, and 28, and the neighboring cells with the signal strength greater than the synchronization threshold of the neighboring cells include the neighboring cells with the numbers of 1, 3, 13, and 28. If a new neighbouring cell is determined according to the first possible embodiment, the new neighbouring cell is a neighbouring cell numbered 13 and a neighbouring cell numbered 21; if a new neighbouring cell is determined according to the second possible embodiment described above, the new neighbouring cells are the neighbouring cell numbered 1 and the neighbouring cell numbered 13.

In the present application, the idle resources of the diversity antenna are used by the terminal device to perform the neighbor cell synchronization task, that is, the terminal device allocates the idle resources of the diversity antenna to the neighbor cell synchronization task.

In some possible embodiments, the terminal device may allocate all idle resources of the diversity antenna to a neighboring cell synchronization task, which may specifically be as shown in fig. 5a or fig. 5d, where, when a receiving mode of the terminal device in a serving cell is a single antenna receiving mode (that is, only a main set antenna is used to receive data sent by the serving cell), resources allocated to the neighboring cell synchronization task by the terminal device are as shown in fig. 5a, and the resources allocated to the neighboring cell synchronization task by the terminal device are resources after resources occupied by a secondary card paging are removed from resources of the diversity antenna; when the receiving mode of the terminal device in the serving cell is a dual-antenna receiving mode (that is, when receiving data sent by the serving cell, the main set antenna and the diversity antenna are used for receiving data simultaneously), the resource allocated to the synchronization task of the neighboring cell by the terminal device is as shown in fig. 5d, and the resource allocated to the synchronization task of the neighboring cell by the terminal device is a resource except for a resource occupied by the secondary card paging and a resource occupied by receiving data of the serving cell from the diversity antenna.

In the present application, the system attribute of the serving cell is introduced in the foregoing, where the system attribute of the serving cell and the service performed by the terminal device in the serving cell are different, and the resource occupied by the secondary card paging is different from the resource occupied by the received data. 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 timeslot (i.e., 0.577ms), and the resource occupied by receiving data is 1 timeslot. In a specific implementation, the resources occupied by the secondary card paging and the resources occupied by the received data and the time length of the resources may be determined according to the system attribute of the serving cell and the service performed by the terminal device, then all idle resources of the diversity antenna are allocated to the neighboring cell synchronization task as shown in fig. 5a or 5b, and the terminal device executes the neighboring cell synchronization task using the resources allocated to the neighboring cell synchronization task as shown in fig. 5a or 5 b.

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

As can be seen from the foregoing, if the system attributes of the neighboring cells are different, the resources required for executing the neighboring cell synchronization task are different, and if the attributes of the neighboring cell synchronization task are different, the resources required for executing the initial neighboring cell synchronization task and the periodic neighboring cell synchronization task are also different. The terminal equipment can determine the system attribute of the adjacent cell corresponding to the adjacent cell synchronous task and the task attribute of the adjacent cell synchronous task; determining a target resource in idle resources of the diversity antenna according to the system attribute and the task attribute; and distributing the target resource to the adjacent region synchronization task.

The target resources allocated to the neighbor synchronization task by the terminal device according to the system attribute of the neighbor and the task attribute of the neighbor synchronization task may be specifically as shown in fig. 5b and 5 c. Under the condition that the adjacent cell synchronization task is a periodic adjacent cell synchronization task, the terminal equipment determines resources occupied by synchronization signals issued by adjacent cells according to system attributes of the adjacent cells; the terminal device determines a second resource in idle resources of the diversity antenna as a target resource, the time length of the second resource needs to be greater than or equal to the time length of the resource occupied by the synchronization signal, and the target resource allocated to a synchronization task of the neighboring cell is shown in fig. 5B, where resource C is the target resource, resource a is the resource occupied by the synchronization signal issued by the neighboring cell, the time length of resource C is greater than or equal to the time length of resource a, the time interval between resource C and resource a is equal to nB1(n is greater than or equal to 1), and B1 is the period of issuing the synchronization signal by the neighboring cell; under the condition that the adjacent cell synchronization task is an initial adjacent cell synchronization task, the terminal equipment determines the period of sending the synchronization signal by the adjacent cell according to the system attribute of the adjacent cell; the terminal device determines a first resource in idle resources of the diversity antenna as a target resource, where the time length of the first resource needs to be greater than or equal to the time length of a cycle for sending a synchronization signal by a neighboring cell, and the target resource allocated to a synchronization task of the neighboring cell is shown in fig. 5c, where resource D is the target resource, B2 is the cycle for sending a synchronization signal by a neighboring cell, and resource D is greater than or equal to the time length of B2. The time length of resource C and resource D in fig. 5b and 5C is determined by the system property of the neighboring cell. For example, in the case that the neighboring cell is a GSM system, the time length of the resource a is 0.577ms, the time length of the resource C is greater than or equal to 0.577ms, the time length of the period for transmitting the synchronization signal in the neighboring cell is 10 frames (46.15ms, the length of 1 to 10/11 to 20/21 to 30/31 to 40 frames in 51 multiframes) or 11 frames (50.765ms, the length of 41 frames in the last 51 multiframes to 0 frame in the current 51 multiframes), and the time length of the resource D is greater than or equal to 11 frames.

In the method and the device, after the target resource in the idle resource of the diversity antenna is allocated to the adjacent cell synchronization task, the terminal device can execute the adjacent cell synchronization task on the target resource, so that the synchronization with the adjacent cell is realized. When the neighboring cell synchronization task is the initial neighboring cell synchronization task, the time required for the terminal device to execute the neighboring cell synchronization task after the method of the present application is implemented is as shown in fig. 7. Taking the neighboring cell corresponding to the neighboring cell synchronization task as an example of the GSM system, and the serving cell is the GSM system, it is assumed that the neighboring cell has issued a synchronization signal once from the resource on the terminal device that has executed the neighboring cell synchronization task last time, the terminal device is synchronizing with another neighboring cell in the resource of the last neighboring cell synchronization task, and paging occupies a resource of 1 time slot in the case that the serving cell is the GSM system. As can be seen from fig. 7, with the solutions of fig. 5a and fig. 5c in the present application, the terminal device can immediately execute the neighbor synchronization task when determining that the scheduling task is the neighbor synchronization task, and can acquire the synchronization signal of the neighbor after 46.15ms, so that the terminal device can synchronize with the neighbor more quickly, and the service of the terminal device is not interrupted in a high-speed motion scene. When the adjacent region synchronization task is the periodic adjacent region synchronization task, the idle resources of the diversity antenna are more than the idle resources of the main set antenna, and more resources can be allocated to the periodic adjacent region synchronization task by implementing the method of the application.

In some embodiments, before the terminal device performs the neighboring cell synchronization task using the idle resource of the diversity antenna, the terminal device may further determine a signal reception state of the diversity antenna of the terminal device, and when the diversity antenna of the terminal device is in the first state, the terminal device performs the neighboring cell synchronization task using the idle resource of the diversity antenna.

Here, the signal reception state of the diversity antenna is used to indicate whether the diversity antenna can normally operate, and when the signal reception state of the diversity antenna is the first state, the signal reception state of the diversity antenna indicates that the diversity antenna can normally operate.

In a possible implementation manner, in a case that the diversity antenna can operate normally, there is a certain requirement for energy of a signal that can be received by the diversity antenna, a signal receiving state of the diversity antenna can be determined by determining whether the energy of the signal received by the diversity antenna meets a set requirement, and the terminal device can obtain a first signal strength of the signal received by the diversity antenna from the target cell, then compare the first signal strength with a signal strength threshold, and determine that the signal receiving state of the diversity antenna is the first state in a case that the first signal strength is greater than the signal strength threshold. In a specific implementation, the terminal device may store the signal strength of each cell detected by the diversity antenna in the last cell signal detection process, and then obtain the first signal strength of the target cell detected by the diversity antenna from the stored signal strength of each cell.

In another possible implementation, in a case that the diversity antenna is capable of operating normally, the diversity antenna and the main set antenna are required to have a smaller energy difference between signals received from the same cell, the signal receiving state of the diversity antenna may be determined by determining the energy difference between the signals received by the diversity antenna and the main set antenna, the terminal device may obtain a first signal strength of the signal received by the diversity antenna from the target cell, obtain a second signal strength received by the main set antenna from the target cell, and determine the signal receiving state of the diversity antenna to be the first state in a case that a difference between the second signal strength and the first signal strength is smaller than a signal strength difference threshold. In a specific implementation, the terminal device may store 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 a first signal strength of a target cell detected by the diversity antenna and a second signal strength of the target cell detected by the main set antenna from the stored signal strength of each cell.

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

By judging the state of the diversity antenna, the normal use of the diversity antenna can be ensured, and the scheme of the application can be normally executed.

In some embodiments, whether to allocate resources to the neighbor synchronization task by using the scheme of the present application may be determined according to a specific scene or environment where the terminal is located.

In a possible scenario, when a signal of a serving cell is good and a signal of a neighboring cell is poor, a terminal device adopts a single-antenna receiving mode, and the neighboring cell needs to be frequently monitored in order to ensure that the neighboring cell can be accessed at any time, that is, when the receiving mode of the terminal device in the current serving cell is the single-antenna receiving mode, the terminal device adopts the scheme of the application, and allocates target resources in idle resources of a diversity antenna to a synchronization task of the neighboring cell; when the signal of the serving cell becomes poor and the signal of the neighboring cell becomes good, the terminal device still performs a service in the serving cell at present, the terminal device adopts a dual-antenna receiving mode, and because the signal of the neighboring cell is improved, the terminal device can detect the neighboring cell more quickly, and the frequency of synchronization of the neighboring cell can be reduced, at this time, the scheme in the dual-antenna receiving mode in the scheme of the present application can be adopted, and the resource allocation scheme shown in fig. 3 can also be adopted. The distribution scheme of the synchronization tasks of the adjacent cells is adjusted according to the receiving mode of the terminal equipment in the service cell, so that the terminal equipment is more suitable for the change of scenes, and the synchronization performance of the terminal equipment is improved.

In another possible scenario, resources may be allocated to the neighboring cell synchronization task according to the state of the terminal device, when the terminal device is in the position transition state, the resource may be allocated to the neighboring cell synchronization task by using the scheme of the present application, and when the terminal device is not in the position transition state, the resource allocation scheme shown in fig. 3 may be used. When the terminal equipment is in the position transfer state, the terminal equipment is possibly in a motion scene at present, and the scheme of the application is adopted to allocate resources to the adjacent region synchronization task, so that the terminal equipment can be ensured to be quickly synchronized with the adjacent region; when the terminal device is not in the position transition state, the resource allocation scheme shown in fig. 3 can meet the synchronization requirement of the terminal device, and in the resource allocation scheme shown in fig. 3, the time allocated to the neighbor cell synchronization task is less, that is, the time for the terminal device to execute the neighbor cell synchronization task is reduced, the frequency of neighbor cell synchronization is reduced, and the power saving effect is achieved.

In one possible implementation, the state of the terminal device can be directly evaluated by adopting the movement speed of the terminal device, and the terminal device is determined to be in the position transition state under the condition that the movement speed is greater than the movement speed threshold value; in another possible implementation, the state of the terminal device may be indirectly evaluated by using a signal strength reduction rate of a signal in a serving cell received by the terminal device, and the terminal device is determined to be in a position transition state when the signal strength reduction rate is greater than a reduction rate threshold; in other possible embodiments, the state of the terminal device may be comprehensively evaluated by combining the movement speed of the terminal device, the acceleration of the terminal device, the signal strength of the serving cell, the signal strength reduction rate of the serving cell, and the like, with the characteristics detected by the terminal device and indicating the movement condition of the terminal device.

After the embodiment is implemented, the terminal can better adapt to the change of scenes or environments, and the synchronization requirements of the terminal in different scenes or environments are met. The time for executing the adjacent cell synchronization task is reduced under the condition of meeting the synchronization requirement of the terminal equipment, the electric quantity consumption of the terminal equipment can be reduced, and the effect of saving electricity is achieved on the premise of ensuring the synchronization requirement of the terminal equipment.
