Description

TECHNICAL FIELD [0001] The present invention relates to a communication realization method and a base station based on hardware reconfiguration of a terminal apparatus,

The present invention relates to a 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 a multi-carrier system based on the 802.16e system and based on Orthogonal Frequency Division Multiplex Access (OFDMA) technology, and the protocol structure is a single medium access control (MAC) entity controls a physical layer (PHY) including a plurality of channels, which may belong to a continuous frequency band or to a discontinuous frequency band.

A base station that supports the 802.16e protocol as an existing base station and supports the 802.16m protocol or supports both the 802.16e protocol and the 802.16m protocol is called an Advanced Base Station (hereinafter referred to as ABS). An existing terminal device can be connected to an advanced base station, but an advanced terminal device can be connected to an advanced base station as well as to an existing base station. The time zone of the advanced base station is divided into two zones: a first zone (also referred to as an ezone zone, a 16 m zone, referred to as MZone below) and a second zone (also referred to as a legacy zone, Legacy Zone, below LZone) . The advanced terminal device may operate in the first area or may operate in the second area by switching to the operating mode of the existing terminal device.

There is one or more fully configured carriers in the 802.16m system that contain all synchronization, broadcast, multicast, and unicast control information, plus information and parameters about multicarrier and other carrier operations. An 802.16m system includes one or a plurality of partially configured carriers including all control channels supporting downlink transmission and used only for downlink transmission. The entire placement carrier can be the primary carrier or the secondary carrier of the terminal device, but the partial placement carrier can be used only as a subcarrier of the terminal device. Each terminal device has only one main carrier for loading control information for controlling operations such as an interactive service and all of the physical layer and the medium access control layer, for example, a network connection. Each terminal apparatus may have one or a plurality of subcarriers and may not have subcarriers. The subcarriers are carriers for service transmission allocated to terminal apparatuses through specified commands and rules of the base station. In addition, It is also possible to transmit control signaling supporting a multicarrier operation in subcarriers.

Currently, there are two types of terminal devices that support multicarrier operation: single radio and multiple radio. One route corresponds to one radio frequency block (RF) of the physical layer.

In an 802.16m multicarrier system, the maximum function of each of the roots of a single-route or multi-route terminal device supporting continuous bandwidth is different, and one or more routes among them can support various upstream downlink bandwidths. In a process of exchanging data between a base station and a base station, a base station allocates one or a plurality of subcarriers to a terminal device based on a load situation of a terminal device and a bandwidth function so as to transmit data, Any one route of the device forms a continuous large bandwidth if it is a continuous frequency band with the carrier in operation. In this situation, the terminal apparatus can adjust the operation bandwidth of the route based on the bandwidth after the subcarriers are allocated. For example, if a single radio wave terminal device can support a maximum bandwidth of 10 MHz, a terminal device starts operating in a bandwidth of 5 MHz, and a base station activates a subcarrier having a bandwidth of 5 MHz that is continuous on the frequency band with the current channel of the terminal device The terminal device can continue the operation by adjusting the operation bandwidth of the route to 10 MHz. In addition, the terminal device can switch the main carrier or switch the area due to the channel quality, load situation, etc. Among them, switching of the main carrier means switching the radio wave currently operating at the main carrier frequency to another carrier Quot; means that the carrier becomes a new main carrier of the terminal apparatus by adjusting the frequency, and the switching of the area means that the terminal apparatus operates by handing off from the first area to the second area or handoffs from the second area to the first area It means to operate.

In this situation, when the terminal device performs switching of the main carrier (the target main carrier is a carrier that the base station has already assigned to the terminal device but is not activated), or switching of the area (the target area is different from the current area Carrier), or when a radio wave route of the terminal device performs the operation bandwidth adjustment, the terminal device should perform hardware reconfiguration, and the arrangement process may be performed by adjusting radio frequency frequency points, Fast Fourier Transformation (Fourier Transform), and the like. However, in the case of performing the reconfiguration in the existing technology, the communication in all the carriers of the route can not 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 the adjustment, It has not been possible to provide a method for realizing the communication under the present invention.

In view of the above problems, the present invention provides a communication realization method based on hardware reconfiguration of a terminal device capable of solving the problem of interruption of communication due to failure to submit a method of realizing communication under a situation where a terminal device performs hardware reconfiguration in the existing technology, And a base station.

According to one aspect of the present invention, a base station transmits a message for instructing switching of a main carrier or an area handoff to a terminal device or activating one or a plurality of subcarriers of the terminal device to a terminal device, And performing a hardware reconfiguration after receiving the message, and if the base station determines that the hardware reconfiguration is completed, the base station performs communication in the carrier after the adjustment with the terminal apparatus, the communication realization method based on the hardware reconfiguration of the terminal apparatus .

The main carrier switching refers to switching the main carrier of the terminal device from the current main carrier to the target main carrier. Of these, the target main carrier refers to a carrier that the base station has 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, of which the target area and the current area are located on different carriers. Activating one or a plurality of subcarriers of a terminal apparatus means activating one or a plurality of subcarriers of the terminal apparatus and the one or more subcarriers are connected to a carrier in which the current radio wave route of the terminal apparatus is active 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 apparatus when exchanging functions with the terminal apparatus. The transmitting unit transmits a message to the terminal device based on the acquired terminal device function, and the message is used for switching the main carrier of the terminal device, area handoff, or subcarrier activation. The determination unit determines whether the terminal device has completed the hardware reconfiguration, and triggers the communication unit when it is determined that the terminal device has completed the hardware reconfiguration. The communication unit performs communication with the terminal apparatus and the adjusted carrier.

According to the present invention, a base station notifies a terminal device to perform a main carrier switching, an area handoff, or a subcarrier activation by transmitting a message to a terminal device, the terminal device performs hardware reconfiguration after receiving the message, It is determined that the hardware reconfiguration has been completed, and communication is continuously performed with the terminal device after the adjustment, thereby preventing the communication from being interrupted in the hardware reconfiguration process of the terminal device and improving the utilization rate of the radio resources.

In view of such problems, 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 to notify the terminal device to perform switching of the main carrier, switching of the area, or activation of the subcarrier, and the terminal device performs hardware reconfiguration after receiving the message, The base station determines whether the terminal device has completed the hardware reconfiguration, and after the base station determines that the terminal device has completed the hardware reconfiguration, the base station continues communication with the terminal device after coordinating with the terminal device.

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

BRIEF DESCRIPTION OF THE DRAWINGS Fig. Hereinafter, the preferred embodiments described below are for illustrating and interpreting the present invention, and the present invention is not limited thereto.

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

FIG. 2 is a flowchart illustrating a communication realization method based on hardware reconfiguration of a terminal device according to an embodiment of the present invention. As shown in FIG. 2, a method for realizing communication based on hardware reconfiguration of a terminal device according to an embodiment of the present invention (Steps 201-203).

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

In the embodiment of the present invention, the hardware reconfiguration performed by the terminal device includes adjusting the radio frequency frequency point of the terminal device or adjusting the number of fast Fourier transform (FFT) points of the terminal device.

Specifically, switching of the main carrier means handing off the main carrier of the terminal apparatus 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 apparatus but has not activated.

The area handoff refers to handoff of a terminal apparatus from a current area to a target area. Among them, the target area is located in a different carrier from the current area, and specifically, it can be handed off from the first area to the second area And may be handed off from the second area to the first area.

Activating one or a plurality of subcarriers of a terminal apparatus means activating one or a plurality of subcarriers for the terminal apparatus, wherein one or a plurality of subcarriers is a carrier in which a current radio wave route of the terminal apparatus is active And a carrier of a continuous frequency band.

In the concrete implementation process, the message includes a carrier management command message (AAI-CM-CMD), a ranging response message (AAI-RNG-RSP), an area handoff message (AAI- -HO-CMD). ≪ / RTI >

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

In the concrete implementation process, the function exchange performed by the base station with the terminal device includes one of multi-carrier basic function interactive, multi-carrier specific function interactive, and other functions other than multi-carrier function.

In a specific application, the base station and the terminal device may transmit a pre-authentication function request / response message (AAI-SBC-REQ / RSP), a registration request / response message (AAI-REG- (AAI-MC-REQ / RSP), but the present invention is not limited thereto.

In a concrete implementation process, if the terminal device is a terminal device of a single radio wave, the base station temporarily stops the communication with the terminal device after transmitting the message to the terminal device. If the terminal device is a terminal device of a multi-radio wave, the base station temporarily stops the communication of the radio wave in all the carriers after transmitting the message to the terminal device, so that the terminal device performs communication on the entire carrier of the radio wave route It is possible to prevent the situation where the data transmitted by the base station can not be received and the data transmitted by the base station is lost.

Step 203: After the base station confirms that the terminal apparatus has completed the hardware reconfiguration, it continues communication with the terminal apparatus and the adjusted carrier.

In a concrete implementation process, the terminal device and the base station can negotiate a time required for hardware reconfiguration of the terminal device in the function exchange process. Specifically, the time required for the terminal device to adjust the radio frequency point, Includes the time required to adjust the number of FFT points, that is, the function of the terminal apparatus acquired by the base station may include the time length, but the terminal apparatus and the base station may not negotiate the time length. With respect to these two situations, embodiments of the present invention describe different implementations of step 203 as follows.

(1) When negotiating the length of time required for hardware reconfiguration of the terminal device

Under this circumstance, the terminal device starts the hardware reconfiguration including one of the radio wave frequency point adjustment and the FFT point number adjustment from the specified time after receiving the message transmitted from the base station. The specific time refers to a time at which the message is received or an operation start time specified in the message. Specifically, the message transmitted by the base station to the terminal device may include a time length required for hardware reconfiguration of the terminal device, and may not include a time length required for hardware reconfiguration of the terminal device. The terminal device can obtain the time length from the message under the circumstances including the time length. The terminal device can perform the hardware reconfiguration from the specific time to the time indicated by the time parameter based on the time parameter exchanged in the function interactive process under the condition that the time length is not included. The time should also include message transmission delays.

Specifically, under such circumstances, the BS can determine whether the terminal device has completed the hardware reconfiguration through the following three methods: (1) The terminal device completes the hardware reconfiguration and performs communication in the carrier after the adjustment After the terminal device is ready, the terminal device instructs the base station, and the base station confirms that the terminal device has already completed the reconfiguration according to the instruction of the terminal device. (2) The base station determines from the time when the message is transmitted whether the terminal apparatus completes the reconstruction through the bandwidth polling message. (3) The base station counts from the time when the message is transmitted, and when the scheduled time comes, the base station confirms that the terminal device has completed the hardware reconfiguration. Specifically, the difference between the scheduled time and the time at which the message is transmitted may be the same as the time length required for hardware reconfiguration of the terminal apparatus, and may be the sum of the time length and the predetermined time length. The predetermined time length is a length of time required for the terminal to adjust the bandwidth to perform synchronization or ranging.

For example, when the first scheme is used, the terminal apparatus can inform the base station through one of the following methods that the terminal apparatus has completed the hardware reconfiguration.

(1) The terminal apparatus can transmit a feedback message to the base station. The feedback message includes feedback information indicating that the terminal device has already completed the hardware reconfiguration and is ready to perform communication in the carrier after the adjustment. Specifically, the feedback message indicates that the unicast terminal device It may be a new feedback message to confirm that the hardware reconfiguration is complete and that it is ready to perform communications on the post-conditioning carrier, and that the terminal device has already completed hardware reconfiguration and is ready to perform communications on the post- May be an existing feedback message including acknowledgment information, e.g., a Carrier Management Acknowledgment message (AAI-CM-IND). Under such circumstances, the BS must allocate the bandwidth required for the terminal apparatus to transmit the instruction to the terminal apparatus.

In the concrete implementation process, the base station may perform the following steps by transmitting the message to the terminal device and then activating the preset timer and counter, among which the counter calculates the number of times the base station has transmitted the message, Is set in advance, specifically, on the basis of the length of time required for hardware reconfiguration of the terminal apparatus. If the time length of the timer is equal to the time length required for hardware reconfiguration of the terminal apparatus desirable.

Step 1, if the timer exceeds the time, but the base station does not receive the feedback message of the terminal, step 2 is performed, otherwise step 5 is performed.

Step 2: Determine whether the counter has reached a preset threshold value, and if yes, perform step 4; otherwise, perform step 3.

Step 3, the base station transmits the message again, the counter counts, the timer is reset, and the process 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 with the terminal after adjusting the carrier.

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

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

For example, if the second scheme is used, the BS can determine whether the MS completes hardware reconfiguration through the following steps.

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

Step 2, the terminal device receives a bandwidth polling message transmitted from the base station, and then transmits a bandwidth request message or a bandwidth requesting head to the base station.

Step 3, when the BS receives the bandwidth request message or the bandwidth request header transmitted from the terminal apparatus, the BS determines that the terminal apparatus has completed the hardware reconfiguration.

More specifically, the 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 a counter. Of these, the counter calculates the number of times the base station transmits the bandwidth polling message.

Step 12, if the timer has exceeded the time, but the base station has failed to receive the bandwidth request message or the bandwidth requesting head returned by the terminal, step 13 is performed, otherwise step 16 is performed.

Step 13, it is judged whether or not the counter has reached a preset threshold value, and if it is reached, Step 15 is performed, otherwise Step 14 is performed.

Step 14, the base station resends the bandwidth polling message again, counts up to 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 with the terminal after adjusting the carrier.

(2) When the hardware reconfiguration time of the terminal device is not negotiated

Specifically, under such a situation, the base station can confirm that the terminal device has completed the hardware reconfiguration through the following two schemes. (I) The terminal device is ready to perform communication in the carrier after completing and adjusting the hardware reconfiguration, and then instructs the base station, and the base station confirms that the terminal device has already completed the hardware reconfiguration based on the instruction of the terminal device. (2) The base station determines from the specific time that the terminal device completes the hardware reconfiguration through the bandwidth polling message and is ready to perform communication in the carrier after the adjustment. A concrete embodiment of these two methods is similar to the above (1), and therefore, a description thereof will be omitted.

In order to further understand the technical solution provided in the embodiment of the present invention, the following concrete embodiments will be described.

Example 1

In this embodiment, the base station allocates one or more subcarriers of a frequency band contiguous to the operating frequency band of the current radio wave to the terminal device, and when the terminal device and the base station exchange functions, the hardware reconfiguration time of the terminal device And the base station determines whether the terminal apparatus has already completed the hardware reconfiguration based on the instruction of the terminal apparatus.

Fig. 3 is a flowchart of the present embodiment. The method for realizing communication between the terminal apparatus and the base station includes the following steps.

Step 301: The terminal device and the base station transmit the hardware reconfiguration time of the terminal device, the maximum continuous bandwidth supported by the receiving radio waves of the terminal device, and the maximum bandwidth of the terminal device through the multi-carrier request / response message (AAI-MC-REQ / RSP) Exchange the maximum continuous bandwidth supported by the credit radio wave.

In step 302, the base station activates one or more subcarriers allocated to the terminal apparatus using the AAI-CM-CMD message, and the base station transmits one AAI-CM-CMD message and operates one timer and one counter , Among which the counter calculates the number of times the base station has transmitted the AAI-CM-CMD message.

Step 303, after receiving the AAI-CM-CMD message, the terminal device performs hardware reconfiguration, for example, adjustment of a radio frequency frequency point, from a specific time to a time indicated by the hardware reconfiguration time parameter.

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

Example 2

In this embodiment, the base station assigns one or more subcarriers to the terminal apparatus and negotiates the time parameters of the hardware reconfiguration of the terminal apparatus when the terminal apparatus and the base station exchange functions, and the base station transmits the bandwidth polling message It is determined that the hardware reconfiguration has already been completed.

Step 403, the terminal device performs hardware reconfiguration, for example, adjustment of a radio frequency frequency point, from a specific time after receiving the AAI-CM-CMD message until the time indicated by the hardware reconfiguration time parameter.

In step 404, after the terminal device is ready to perform communication in the carrier after completing and adjusting the hardware reconfiguration, the terminal device does not transmit the feedback information, and the base station transmits a bandwidth polling message to the terminal device in a new bandwidth spontaneously, The apparatus transmits a bandwidth request message or a bandwidth requesting head to the base station to indicate that the terminal apparatus has completed the reconfiguration and is ready to perform communication on the carrier after the adjustment. The base station transmits a bandwidth polling message and sets one timer and one counter. If the timer has exceeded the time limit but fails to receive the bandwidth request of the terminal apparatus, the terminal apparatus recognizes that the terminal apparatus has not completed the reconfiguration. If the bandwidth request of the terminal device is received before the counter reaches the predetermined threshold value, the timer and the counter are stopped and communication with the terminal device is started at the new bandwidth. If the threshold value set in advance is exceeded but the bandwidth request of the terminal apparatus is not received, the terminal apparatus recognizes that the terminal apparatus must again perform synchronization with the base station.
