Description

TECHNICAL REALIZATION METHOD AND BASE STATION BASED ON TERMINAL HARDWARE RECONFIGURATION}

The present invention relates to the field of mobile communication technology, and more particularly, to a communication realization method and a base station based on hardware reconfiguration of a terminal device.

The 802.16m system is an evolved base on the 802.16e system and is a multi-carrier system based on Orthogonal Frequency Division Multiplex Access (OFDMA) technology. The protocol structure is a single medium access control as shown in FIG. An entity controls a physical layer (called a Physical, below PHY) that contains multiple channels, and these channels may belong to a continuous frequency band or to a non-continuous frequency band.

A base station supporting the 802.16e protocol is called an existing base station, and a base station supporting the 802.16m protocol or simultaneously supporting the 802.16e protocol and the 802.16m protocol is called an advanced base station (hereinafter referred to as ABS). The existing terminal device may be connected to the advanced base station, but the advanced terminal device may be connected to the existing base station as well as to the advanced base station. The time zone of the advanced base station is divided into two zones: the first zone (also called M zone, 16m zone, below MZone) and the second zone (also called legacy zone, legacy zone, below LZone). . The advanced terminal device may operate in the first area or switch to the operation method of the existing terminal device to operate in the second area.

There is one or more fully configured carriers in the 802.16m system that contain all the synchronization, broadcast, multicast and unicast control information, and further include information and parameters for multicarrier and other carrier operations. There is also one or multiple partially configured carriers that include all control channels supporting downlink transmission in the 802.16m system and are used only for downlink transmission. All batch carriers may be a primary carrier or a secondary carrier of a terminal device, but a partial carrier may be used only as a subcarrier of a terminal device. In each terminal device, there is only one main carrier carrying interactive information and control information for controlling operations such as network connection of all physical layers and media access control layers. Not only one or more subcarriers may exist in each terminal device but also no subcarriers may exist, and the subcarriers are carriers for service transmission allocated to the terminal devices through specific commands and laws of the base station. Control signaling supporting multi-carrier operation may be transmitted in a subcarrier.

Currently, there are two types of terminal apparatuses that support multi-carrier operation, a single route and a multiple route. One route corresponds to one Radio Frequency Block (hereinafter referred to as RF) of the physical layer.

In the 802.16m multi-carrier system, the maximum function of each route of a single route or a multi-route terminal device to support consecutive bandwidths is different, and one or more routes may support various uplink and downlink bandwidths. In the process of the base station exchanging data (interactive), the base station allocates one or more subcarriers to the terminal device and transmits the data based on the load condition and bandwidth function of the terminal device. If one route of the device is a frequency band contiguous with the carrier in operation, it forms one contiguous large bandwidth. In this situation, the terminal apparatus may adjust the operation bandwidth of the route based on the bandwidth after allocating the subcarriers. For example, a single radio terminal can support a maximum bandwidth of 10 MHz and the terminal starts to operate at a bandwidth of 5 MHz, and the base station activates a subcarrier with 5 MHz of contiguous bandwidth on the terminal's current channel and frequency band. After that, the terminal device can adjust the operation bandwidth of the route to 10 MHz to continue the operation. In addition, the terminal equipment may perform switching of the main carrier or switching of the area due to channel quality, load conditions, etc. Of these, the switching of the main carrier means that the radio wave route currently operating at the main carrier frequency is different from the carrier. The frequency is controlled so that the carrier becomes the new main carrier of the terminal device. The switching of the area means that the terminal device operates by handing off from the first area to the second area or by handing off from the second area to the first area. It works.

In the above situation, when the terminal apparatus switches the main carrier (the target main carrier is a carrier that the base station has already assigned to the terminal apparatus but has not activated), or the switching of the region (the target region is different from the current region). Located in the carrier), or if any radio route of the terminal device adjusts the operating bandwidth, the terminal device must perform hardware reconfiguration, and the arrangement process is performed by adjusting radio frequency points, Fast Fourier Transformation, and the like. However, in the existing technology, when reconfiguration is performed, communication on all carriers of the route cannot be stopped, and after the terminal device completes the hardware reconfiguration, the terminal device and the base station continue to communicate in the carrier after adjustment. Failed to submit how to implement communications under

In view of the above problems, the present invention provides a method for realizing communication based on hardware reconfiguration of a terminal device that can solve a problem in which communication is interrupted due to failure to submit a plan for realizing communication in a situation where the terminal device performs hardware reconfiguration. It is an object to provide a base station.

According to an aspect of the present invention, the base station instructs the terminal device to switch main carriers or perform area handoff, or transmits a message to the terminal device to activate one or multiple subcarriers of the terminal device. After receiving the message, and performs a hardware reconfiguration, and if the base station determines that the terminal has completed the hardware reconfiguration, the communication realization method based on the hardware reconfiguration of the terminal device comprising the step of performing communication in the carrier after adjusting with the terminal device To provide.

The main carrier switching refers to the switching of the main carrier of the terminal device from the current main carrier to the target main carrier, wherein the target main carrier refers to a carrier which the base station assigns to the terminal device but does not activate. Area handoff refers to handoff of a terminal device from a current area to a target area, wherein the target area and the current area are located on different carriers. Activating one or multiple subcarriers of a terminal equipment means activating one or multiple subcarriers of the terminal equipment, the one or more subcarriers being contiguous with the carrier on which the current radio route of the terminal equipment is operating. It is preferable that it is a carrier of a frequency band.

According to another aspect of the present invention, a base station is provided.

A base station according to the present invention includes an acquisition unit, a transmission unit, a determination unit, and a communication unit. Among them, the acquisition unit acquires the maximum continuous bandwidth reception function and the maximum continuous bandwidth transmission function of the terminal device when exchanging functions with the terminal device. The transmitting unit transmits a message to the terminal apparatus based on the acquired terminal apparatus function, and the message is used for main carrier switching, area handoff or subcarrier activation of the terminal apparatus. The judging unit judges whether the terminal apparatus has completed the hardware reconfiguration, and triggers the communication unit when judged that the terminal apparatus has completed the hardware reconfiguration. The communication unit communicates with the terminal device in the carrier after adjustment.

According to the present invention, the base station transmits a message to the terminal device and notifies the terminal device to perform main carrier switching, area handoff, or subcarrier activation, and the terminal device performs hardware reconfiguration after receiving the message. After determining that the hardware reconfiguration has been completed, communication is performed on the carrier after adjusting with the terminal device, thereby preventing communication from being interrupted during the hardware reconfiguration process of the terminal device and improving the utilization of radio resources.

In view of such a problem, an embodiment of the present invention provides a communication realization method based on hardware reconfiguration of a terminal device. In an embodiment of the present invention, the base station transmits a message and notifies the terminal device to perform main carrier switching, area switching or subcarrier activation, and the terminal device performs hardware reconfiguration after receiving the message. The base station determines whether the terminal equipment has completed the hardware reconfiguration, and after the base station determines that the terminal equipment has completed the hardware reconfiguration, the base station continuously performs communication with the terminal after adjusting with the terminal equipment.

Here, the features described in the embodiments and the embodiments of the present invention can be combined with each other under mutually inconsistent circumstances.

The preferred embodiment of the present invention will be described by combining the drawings below. Here, the preferred embodiments described below are for explaining and interpreting the present invention, but the present invention is not limited thereto.

According to an embodiment of the present invention, first, a communication realization method based on hardware reconfiguration of a terminal device is provided.

2 is a flowchart illustrating a communication realization method based on hardware reconfiguration of a terminal apparatus according to an embodiment of the present invention. As shown in FIG. 2, a communication realization method based on hardware reconfiguration of a terminal apparatus according to an embodiment of the present invention is described below. Steps 201 to 203 are included.

Step 201: The base station transmits a message to the terminal apparatus, which instructs the terminal apparatus to perform main carrier switching, or instructs the terminal apparatus to perform area handoff, or to select one or multiple subcarriers of the terminal apparatus. The terminal device performs hardware reconfiguration after receiving the message.

In an embodiment of the present invention, the hardware reconfiguration performed by the terminal apparatus includes, but is not limited to, adjusting radio frequency frequency points of the terminal apparatus or fast Fourier (FFT) point number of the terminal apparatus.

Specifically, switching of the main carrier refers to handing off the main carrier of the terminal device from the current main carrier to the target main carrier, wherein the target main carrier is a carrier that the base station has already assigned to the terminal device but has not activated.

Area handoff refers to handoff of a terminal device from a current area to a target area, wherein the target area is located on a carrier different from the current area, and specifically, the handoff can be handed off from the first area to the second area. The handoff may be performed from the second area to the first area.

Activating one or multiple subcarriers of a terminal equipment means activating one or multiple subcarriers for the terminal equipment. The one or multiple subcarriers are carriers on which one of the current radio wave routes of the terminal equipment is operating. And is a carrier of consecutive frequency bands.

In a specific embodiment, the message may include a carrier management command message (AAI-CM-CMD), a ranging response message (AAI-RNG-RSP), an area handoff message (AAI-ZS-CMD), and a handoff command message (AAI). -HO-CMD), but is not limited thereto.

In a specific embodiment, before the base station transmits the message for main carrier switching, area handoff, or subcarrier activation to the terminal device, the base station may first acquire a function of the terminal device by performing a function exchange with the terminal device. Specifically, the function of the terminal device includes, but is not limited to, the maximum continuous bandwidth supported by the reception radio wave of the terminal device and the maximum continuous bandwidth supported by the transmission radio wave of the terminal device.

In a specific embodiment, the function exchange performed by the base station with the terminal device includes, but is not limited to, one of multi-carrier basic functional interactive, multi-carrier specific functional interactive, and other functional interactive except the multi-carrier functional.

In a specific application, the base station and the terminal equipment may use a pre-authentication function request / response message (AAI-SBC-REQ / RSP), a registration request / response message (AAI-REG-REQ / RSP), and a multicarrier request / The function exchange may be performed through one of the response messages (AAI-MC-REQ / RSP), but is not limited thereto.

In a specific embodiment, if the terminal device is a single radio wave terminal device, the base station temporarily stops communication with the terminal device after transmitting the message to the terminal device. If the terminal equipment is a multi-radio wave terminal device, the base station temporarily stops communication of the radio wave route on all carriers after transmitting the message to the terminal device so that the terminal device can communicate on all carriers of the radio wave route. The interruption prevents the base station from receiving data transmitted by the base station and thus loses data transmitted by the base station.

Step 203: The base station determines that the terminal equipment has completed the hardware reconfiguration, and continues to communicate in the carrier after adjusting with the terminal equipment.

In a specific embodiment, in the function exchange process, the terminal device and the base station may negotiate time required for hardware reconfiguration of the terminal device. Specifically, the time required for the terminal device to adjust the radio frequency point, the terminal device. Includes the time required to adjust the number of FFT points, i.e., the time length may be included in the function of the terminal equipment acquired by the base station, but the terminal equipment and the base station may not negotiate the length of time. For these two situations, the embodiment of the present invention describes the different implementation manners in step 203 as follows.

(一) negotiating the length of time required for hardware reconfiguration of the terminal device;

Under these circumstances, the terminal equipment starts hardware reconfiguration including one of radio frequency point adjustment and FFT point adjustment from a specified time after receiving the message transmitted by the base station. Among these, the specific time refers to the time at which the message is received or the operation start time specified in the message. In detail, the message transmitted by the base station to the terminal device may include a length of time required for hardware reconfiguration of the terminal and may not include a length of time required for hardware reconfiguration of the terminal. Under the circumstances including the time length, the terminal apparatus can obtain the time length from the message. In a situation where the time length is not included, the terminal device may perform hardware reconfiguration from a specific time to a time indicated by the time parameter based on the time parameter exchanged in the functional interactive process. The time should also include a message transmission delay.

Specifically, under such a situation, the base station can determine whether the terminal device has completed the hardware reconfiguration through the following three methods: (1) The terminal device has completed the hardware reconfiguration and can perform communication in the carrier after adjustment. After the preparation, the terminal equipment instructs the base station, and the base station determines that the terminal equipment has already completed the reconfiguration according to the terminal equipment. (II) The base station determines whether the terminal apparatus has completed the reconfiguration through the bandwidth polling message from the time of transmitting the message. (三) The base station counts from the time at which the message was transmitted, and when the scheduled time comes, the base station determines that the terminal equipment has completed the hardware reconfiguration. Specifically, the difference between the scheduled time and the time at which the message is transmitted may be equal to the length of time required for hardware reconfiguration of the terminal, and may be the sum of the length of time and the predetermined length of time. The predetermined length of time is the length of time required for the terminal device to perform synchronization or ranging by adjusting bandwidth.

For example, when the first method is used, the terminal device can notify the base station that the terminal device has completed the hardware reconfiguration through one of the following methods.

(1) The terminal apparatus can transmit a feedback message to the base station. Among them, the feedback message includes feedback information indicating that the terminal apparatus has already completed the hardware reconfiguration and is ready to perform communication on the carrier after the adjustment, and specifically, the feedback message is already received by the unicast terminal apparatus. May be a new feedback message to confirm that the hardware reconfiguration has been completed and is ready to perform communication on the carrier after the adjustment and that the terminal has already completed the hardware reconfiguration and is ready to perform communication on the carrier after the adjustment It may be an existing feedback message including confirmation information, for example, a carrier management confirmation message (AAI-CM-IND). Under such circumstances, the base station should allocate a bandwidth necessary for the terminal to transmit an indication to the terminal.

In a specific embodiment, the base station may perform the following steps by operating a timer and a counter set in advance after transmitting the message to the terminal device, wherein the counter counts the number of times the base station transmits the message and the timer. The time length set in FIG. 1 is a preset value, and specifically, may be set based on the time length required for hardware reconfiguration of the terminal device. The time length of the timer is equal to the time length required for hardware reconfiguration of the terminal device. desirable.

Step 1, if the timer has timed out, but the base station does not receive the feedback message of the terminal device performs step 2, otherwise performs step 5.

In step 2, it is determined whether the counter has reached a preset threshold, and if it has reached step 4, otherwise step 3 is performed.

Step 3, the base station sends the message again, the counter counts, resets the timer and returns to step 1.

Step 4, it is determined that the terminal apparatus should realize synchronization again with the base station.

Step 5, the timer and the counter are stopped and the base station starts communication again on the carrier after adjusting with the terminal equipment.

(2) The terminal device transmits a code for requesting bandwidth on the carrier after adjustment, indicating that the terminal device has already completed hardware reconfiguration and is ready to perform communication on the carrier after adjustment.

(3) The terminal device transmits the adjustment completion confirmation information on the feedback channel to indicate that the terminal device has already completed the hardware reconfiguration and is ready to perform communication on the carrier after the adjustment.

For example, using the second method, the base station can determine whether the terminal apparatus has completed the hardware reconfiguration through the following steps.

Step 1, the base station transmits a bandwidth polling message to the terminal device.

Step 2, after receiving the bandwidth polling message transmitted by the base station, the terminal device transmits a bandwidth request message or a bandwidth request head to the base station.

Step 3, when the base station receives the bandwidth request message or bandwidth request head sent by the terminal device, the base station determines that the terminal device has completed the hardware reconfiguration.

Specifically, Steps 1 to 3 are realized through the following steps.

In step 11, the base station transmits a bandwidth polling message to the terminal device to operate a preset timer and counter, wherein the counter counts the number of times the base station transmits the bandwidth polling message.

Step 12, if the timer has timed out, but the base station has not received the bandwidth request message or bandwidth request head returned by the terminal equipment, performs step 13; otherwise, performs step 16.

Step 13, it is determined whether the counter has reached a preset threshold, and if so, step 15 is performed; otherwise, step 14 is performed.

Step 14, the base station resends the bandwidth polling message, counts up with a count, resets the timer, and returns to step 12.

Step 15, it is determined that the terminal apparatus should realize synchronization again with the base station.

Step 16, the timer and the counter are stopped and the base station starts communication on the carrier after adjusting with the terminal equipment.

(二) does not negotiate the hardware reconfiguration time of the terminal device

Specifically, under these circumstances, the base station may determine that the terminal apparatus has completed the hardware reconfiguration through the following two methods. (I) After the terminal device is ready to perform communication on the carrier after completing and adjusting the hardware reconfiguration, the terminal device instructs the base station, and the base station determines that the terminal device has already completed the hardware reconfiguration based on the indication of the terminal device. (II) The base station determines from the specific time point through the bandwidth polling message whether the terminal equipment has completed the hardware reconfiguration and is ready to perform communication on the carrier after adjusting. Specific embodiments of these two methods are similar to the above (1), and thus description thereof is omitted.

In order to further understand the technical solution provided in the embodiment of the present invention will be described through the specific examples below.

Example 1

In the present embodiment, the base station allocates one or multiple subcarriers of a frequency band continuous to the operating frequency band of the current radio wave route to the terminal device, and when the terminal device and the base station exchange functions, the hardware reconfiguration time of the terminal device is set. After negotiation, the base station determines whether the terminal device has already completed hardware reconfiguration based on the terminal device's instructions.

Step 303, after receiving the AAI-CM-CMD message, the terminal equipment performs hardware reconfiguration, for example, adjusting radio frequency points, from a specific time until a time indicated by the hardware reconfiguration time parameter.

Step 304, after the terminal device is ready to perform communication on the carrier after completing and adjusting the hardware reconfiguration, the terminal device transmits a unicast feedback message to the base station in the bandwidth allocated by the base station and before the timer expires. If the feedback message is received, it continues to communicate with the terminal device in the new bandwidth.

In step 404, after the terminal apparatus is ready to perform communication on the carrier after completing and adjusting the hardware reconfiguration, the terminal apparatus does not transmit feedback information and the base station dynamically transmits a bandwidth polling message to the terminal apparatus at the new bandwidth. The device sends a bandwidth request message or bandwidth request head to the base station to indicate that the terminal equipment has completed reconfiguration and is ready to perform communication on the carrier after adjusting. The base station sets one timer and one counter after transmitting the bandwidth polling message. If the timer has timed out but fails to receive the bandwidth request from the terminal, the base station acknowledges that the terminal has not completed the reconfiguration and the base station polls the polling message. Resends the timer and sets 1 to the counter.If the terminal receives a bandwidth request before the counter reaches a preset threshold, it stops the timer and counter and starts communication with the terminal at the new bandwidth. If the preset threshold is exceeded but the bandwidth request of the terminal device is not received, the terminal device recognizes that the terminal device should synchronize with the base station again.
