Description

 Using different wireless access technologies

 Method and device for coexistence between networks

 The present invention relates to wireless communication networks, and more particularly to a method for enabling coexistence between multiple wireless communication networks using different wireless access technologies. Background technique

 In the current field of wireless communications, the wireless spectrum is becoming more and more crowded due to the increasing amount of traffic. Thus, the coexistence of individual wireless communication networks in scarce frequency resources becomes increasingly important. In coexistence, wireless communication networks can safely use wireless communication resources that belong to other wireless communication networks but have not yet been used, so that spectrum resources can be fully utilized and utilization can be improved. For example, IMT-advanced requires wireless communication networks using different Radio Access Technologies (RATs) to have coexistence capabilities with each other to improve spectrum utilization. Similarly, in the IEEE 802.16m Network Requirement Document (SRD), it is also explicitly mentioned that the 802.16m network should be deployable in the same or overlapping area of the other RAT-based wireless communication network, the other wireless communication The network topology of the network may be the same as or different from the 802.16m network. Therefore, the 802.16m network should share the frequency band with the other wireless communication networks.

 In general, coexistence involves two aspects of work. First, it is necessary to determine idle communication resources that are not occupied in the current channel; second, each wireless communication network should negotiate how to use idle resources. In the existing IEEE 802.22 Wireless Regional Area Network (WRAN), the WRAN network monitors whether the communication channel contains various signals in the main TV system one by one, for example, based on ATSC (Advanced Television Network Committee), NTSC ( National Television Standards Committee), DVB-T (Digital Television Terrestrial Broadcasting), wireless microphone and other standard signals to determine whether the communication channel and the corresponding communication resources are occupied by the TV system, and thus can be determined by this The idle communication channel and communication resources occupied by the WRAN network. Then, the WRAN network sends a beacon in the self-coexistence window in the occupied communication channel, and the beacon includes the occupation of the WRAN network.

Confirmation Information about the resource, for other WRAN networks to receive and coexist.

 The current IEEE 802.22 technology has two major drawbacks: First, when coexisting with a heterogeneous TV system as the primary wireless communication network, it is necessary to monitor various types of TV data service signals, which makes it necessary to join the network design. The detection function of various types of signals; and, monitoring the long-time monitoring time one by one, and reducing the network performance; meanwhile, if the TV system is updated to transmit a new type of data service signal, the WRAN network must also be reconfigured so that This new signal can be monitored, which reduces the ease of monitoring and the ease of operation of the network. Secondly, when coexisting with other wireless communication networks, the coexisting beacons sent by them are only suitable for the homogeneous wireless communication network using the same RAT and physical layer specifications, that is, the WRAN receives, and the heterogeneous wireless communication network based on different RATs. In particular, the heterogeneous wireless communication network based on the new RAT cannot receive the coexisting beacon, and then it is difficult to coexist with the WRAN network through the coexisting beacon. Time coexistence in wireless communication networks using different RATs is a difficult task, because wireless communication networks using different RATs are usually based on different physical layer profiles (Physical Layer Profiles), such as different bandwidths, positive The fast Fourier transform (FFT) size, coding mode, modulation mode, transmission rate, etc. of the frequency division multiplexing (OFDM) are performed to perform data service and control signaling transmission in and between cells. Therefore, it is difficult for these heterogeneous wireless communication networks using different RATs to negotiate communication between them. In addition, existing wireless communication networks have difficulty changing their original design to achieve coexistence with other RATs, particularly recently developed wireless communication networks.

 Therefore, based on the coexistence technology of existing wireless communication networks, the monitoring of available communication resources is very complicated, and it is also difficult to achieve coexistence between heterogeneous wireless communication networks using different RATs and physical layer specifications.

 Referring now to Figures 2 to 5, the specific implementation of the present invention will be described in detail from the perspective of the network method:

 First embodiment

 1 is a schematic diagram showing a topology of a primary wireless communication network 1 and a shared memory from a wireless communication network 2 and 3, wherein the primary wireless communication network 1 is an IEEE 802.16m-based communication, in accordance with an embodiment of the present invention. a network comprising a base station 10 and a mobile terminal 11, the mobile terminal 11 being adjacent to the slave wireless communication network 2; the slave wireless communication network 2 is also an IEEE 802.16m network, but the physical layer specification of the data service transmission and the primary wireless communication network According to the physical layer specification of the service transmission, the base station 20 and the mobile terminal 21, the mobile terminal 21 and the slave wireless communication network 3 are adjacent; the wireless communication network 3 is another standard network, and the data service transmission thereof The physical layer specification differs from the physical layer specification for data traffic transmission from the wireless communication network 2, which includes the base station 30 and the mobile terminal 31. The scenario of coexistence is as follows: The primary wireless communication network 1 has the right to decide on the communication resources it owns, that is, the slave wireless communication network 2 coexisting with it cannot occupy the communication resources that it has allocated and used, but can temporarily use the primary wireless communication network 1 temporarily. Allocate the communication resources used.

A flow chart of the method of coexistence. DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS Referring now to Figures 1 and 2, a method of coexistence between a primary wireless communication network 1 and a wireless communication network 2 will be described in detail in accordance with the present invention.

 In general, when the primary wireless communication network allows coexistence from the wireless communication network 2, its base station 10 can instruct the mobile terminal within its jurisdiction to issue coexistence related information to the secondary wireless communication network 2 by instructions. A person skilled in the art can understand that it is not necessary to issue the instruction, for example, the mobile terminal 2 can also periodically acquire coexistence related information. Thereafter, the operation according to the present invention performed by the mobile terminal 11 will be as follows.

 First, in step S110, the mobile terminal 11 of the primary wireless communication network 1 acquires coexistence related information and a unified physical layer specification, wherein the coexistence related information is used by the primary wireless communication network 1 with heterogeneous slave wireless Communication network 2 coexisting information, the unified physical layer specification is a physical layer specification that can be detected by heterogeneous detection from the wireless communication network 2.

 For the coexistence related information, on the one hand, in step S100, it can be generated by the base station 10 of the primary wireless communication network 1, and transmitted to the mobile terminal 11 in step S101. Specifically, the coexistence related information may include the following information:

 1. The base station 10 generates, as the coexistence related information, the information of the uplink/downlink communication resources that it has allocated and communicates with the mobile terminal 11, and transmits the information to the mobile terminal 11, such as a subcarrier, a frequency, a time slot, and the like. As a beacon that the communication resource has been occupied. In this way, the other wireless communication network that receives the coexistence related information knows that the communication resource is already occupied by the primary wireless communication network 1, and should avoid using the resource to avoid mutual interference with the primary wireless communication network 1, and better Protect the primary wireless system;

2. The base station 10 generates, as coexistence related information, information of a plurality of communication resources that have been allocated for communication with other devices, and transmits the information to the mobile terminal 1 1 , for example, in each frame that has been allocated in the wireless communication network. Each subcarrier, frequency, time slot, etc., is a beacon that has been occupied by these communication resources. In this way, other wireless communication networks that receive the coexistence related information are aware that the plurality of communication resources are already occupied by the primary wireless communication network 1, and should avoid using the multiple resources to avoid mutual interference with the primary wireless communication network 1. , to better protect the main wireless system, and also to provide information of multiple occupied resources to other wireless communication networks at one time, reducing the monitoring time of other wireless communication networks; 3. The base station 10 may also generate, as the coexistence related information, the information of the communication resources of the wireless communication network that has not been allocated the unused partial resources and the shared cooperation information of the idle partial resources, and send the information to the mobile terminal, for example, a certain time. The slots and subcarriers are still idle, so that other wireless communication networks that receive the coexistence related information can learn that the part of resources are not yet used, and they can negotiate with the main wireless communication network 1 for these idle resources, and use them by temporary borrowing or the like. These idle resources improve spectrum utilization.

 It can be understood that a plurality of the above information may be sent, or may be sent alternatively. For example, in the primary wireless communication network, it merely indicates that the resource is already occupied; and in the secondary communication network, it may further include idle resource information and cooperation information and the like. The coexistence related information is not limited to the above examples, and those skilled in the art can determine appropriate coexistence related information according to the actual network and actual needs, and all information for coexistence with the heterogeneous wireless communication network should be in the present invention. Within the scope of the claims.

 After the base station 10 generates the coexistence related information, the base station 10 provides the coexistence related information to the mobile terminal 11 in step S101. Preferably, the base station 10 provides the Beacon IE to the fixed resource block of the downlink communication resource. Mobile terminal 1 1 ; In another case, the base station 10 can also use the data service resource block between it and the mobile terminal 11 to provide the Beacon IE or the valid information therein to the mobile terminal in the form of data service. Then, in step S1 10, the mobile terminal 11 receives the coexistence related information from the base station 10.

 For the coexistence related information, on the other hand, if the mobile terminal 11 is communicating with the base station 10, it can itself know the uplink/downlink communication resources that have been allocated and used between the mobile terminal and the base station, such as subcarriers, frequencies, and time slots. Wait. Then, the mobile terminal 11 can generate corresponding coexistence related information according to the communication resource as a beacon that the communication resource has been occupied. In this way, the other wireless communication network that receives the coexistence related information knows that the communication resource is already occupied by the primary wireless communication network 1, and should avoid using the resource to avoid mutual interference with the primary wireless communication network 1, and better Protect the primary wireless system.

For the unified physical layer specification, in order to allow each different data service to transmit the physical layer The canonical heterogeneous wireless communication network can receive coexistence related information issued based on the unified physical layer specification, which is a physical layer specification that can be detected by a heterogeneous wireless communication network. For example, it is a waveform different from the waveform for data communication transmission of the wireless communication network 1, and the encoding and modulation method for carrying the coexistence related information can be demodulated and decoded by the heterogeneous wireless communication communication network; The wireless communication network makes the waveform known and can easily detect, demodulate and decode the coexisting related information from the transmitted signal of the wireless communication network 1. In this case, each heterogeneous wireless communication network should be designed to detect signals of such waveforms and perform corresponding demodulation and decoding. It can be understood that designing a physical layer specification that can be detected by a heterogeneous wireless communication network is not a problem of the present invention. Those skilled in the art having knowledge of physical layer specification design such as waveform design can design according to actual needs. A suitable unified physical layer specification is provided to provide the coexistence related information to the heterogeneous infinite communication network, and the present invention will not be described herein. The unified physical layer specification may be solidified in the subscriber identity module (SIM) of the mobile terminal 1 or the mobile terminal user, or may be negotiated with the base station 1 1 when the mobile terminal 11 accesses the wireless communication network 1. .

 Then, in step S11, the mobile terminal 11 transmits the acquired coexistence related information based on the unified physical layer specification. Preferably, the mobile terminal 11 can use the information element (Information Element, IE for short) in the wireless communication system to accommodate the coexistence related information. The data structure of such a beacon information unit (Beacon IE) can be as follows: Table 1 : Beacon Information Unit

 Retaining Information Units It will be appreciated that one of ordinary skill in the art can change the data structure of beacon information units that accommodate their coexisting related information accordingly, depending on actual needs.

 Preferably, the mobile terminal 1 1 transmits the coexistence related information using the cognitive resource block in the communication resource of the wireless communication network. Specifically, the location of the cognitive resource block can be as shown in the figure

3 is shown. Each superframe includes four frames, where the first frame 1 in the superframe includes a preamble (Preamble), a superframe control header (SCH) carrying basic system information, and a frame control header of the current frame. (Frame Control Header, FCH for short) and Resource Mapping Table (MAP). Frame 2, Frame 3 and Frame 4 respectively include FCH and MAP of this frame. At the end of the frame 4, a cognitive resource block is drawn, which is specifically used by the mobile terminal 11 to transmit coexistence related information. Specifically, the coexistence related information may be accommodated in a beacon MAC (Media Access Control) payload in the form of a beacon information unit, and together with the beacon MAC header and the CRC (Cyclic Redundancy Check) code constitute a beacon MAC PDU. (Protocol Data Unit); The beacon MAC PDU, together with the preamble symbol, constitutes a beacon, which is transmitted by the mobile terminal 1 1 based on a unified physical layer specification, wherein the preamble symbol is used to assist the heterogeneous coexistence network to receive the beacon. It is worth noting that in the primary wireless communication network, since it only needs to transmit the beacon without receiving the beacon of other wireless communication systems, the length of the cognitive resource block can be shortened to be the same as the beacon to reduce the system overhead; In the wireless communication network, which will be described hereinafter, since it not only needs to transmit a beacon but also needs to receive beacons sent by other wireless communication networks, the length of the cognitive resource block should be longer to accommodate multiple resources. Target transmission, so that the system randomly and competitively emits beacons. In order to avoid conflicts with beacons sent by other networks, the location other than the beacon sent by the system is null (Null). The information such as the location, length, and the like of the cognitive resource block may be defined by the base station 10 in the superframe N to which the resource block belongs, or the resource mapping table in the associated frame 3, and provided to each mobile terminal. It is to be noted that, in order to save resources, the base station 10 does not necessarily have to command all mobile terminals under its jurisdiction to issue coexistence related information, but only commands to be transmitted from the mobile terminal 1 in the vicinity of the wireless communication network 2. Then, the mobile terminal that sends the beacon can transmit the coexistence related information according to the other, and the other mobile terminal should keep silent in the cognitive resource block to avoid interference on the propagation of the coexistence related information.

 In another case, base station 10 can also issue the coexistence related information (not explicitly shown in Figure 1). Specifically, in step S101, similar to the above-mentioned mobile terminal 11 transmitting coexistence related information, the base station 10 transmits the coexistence related information in the cognitive resource block in the communication resource of the present wireless communication network based on the unified physical layer specification. . It can be understood that the coexistence related information can be transmitted by any one of the mobile terminal 11 and the base station 10, or both.

 In the above embodiment, the example is mainly used for the coexistence of the primary wireless communication network 1 and a heterogeneous wireless communication network 2, wherein the coexistence related information is used by the wireless communication network 1 for coexistence with the heterogeneous wireless communication network 2. The information, unified physical layer specification is a physical layer specification that can be detected by the base station and the mobile terminal in the heterogeneous wireless communication network 2, including 2. It can be understood that the present invention also has backward compatibility, that is, can also be used for the same layered wireless communication network as the physical layer specification of the data communication transmission of the present wireless communication network. In this case, the coexistence related information is also used to coexist with the homogeneous wireless communication network, and the unified physical layer specification can also be detected by the homogeneous wireless communication network. The specific implementation method is similar to the foregoing manner of coexistence with a heterogeneous wireless communication network, and is not described herein.

In the above embodiment, the main wireless communication network is exemplified. It can be understood that the above method can also be used from the wireless communication network, and the coexistence related information can be provided to other secondary wireless communication networks to realize coexistence with other secondary wireless communication networks. The coexistence related information may indicate its own communication resource, and may also indicate a coexisting communication resource obtained by coexistence with the main network. In the case of the latter coexistence, preferably, the base station First, the communication resources that are available from the wireless communication network and coexist with the primary wireless communication network are determined, and the communication resources of the wireless communication network are determined. For example, a method similar to the WRAN of IEEE 802.22 is used to determine a communication resource that can coexist with the main network by scanning data service communication of the primary network in a channel one by one; it can also be used according to the present invention, as will be described below, Receiving coexistence related information sent by the primary network and then determining a method of coexisting resources, and determining communication resources that can coexist with the primary network.

 After the mobile terminal 11 and the base station 10 issue the coexistence related information based on the unified physical layer specification, since the unified physical layer specification can be implemented by the heterogeneous detection from the wireless communication network 2, that is, at the base station of the heterogeneous slave wireless communication network 2 The unified physical layer specification should be supported at the beginning of the design of the mobile terminal and/or mobile terminal.

 Then, in step S200, the base station 20 acquires the coexistence related information. Specifically, in step S200, the heterogeneous base station 20 of the wireless communication network 2 monitors the coexistence transmitted by the base station 10 and/or the mobile terminal 11 of the heterogeneous wireless communication network 1 in a broadcast manner based on the unified physical layer specification. Related Information. Preferably, base station 20 monitors on the communication resource blocks it wishes to use.

 Since the unified physical layer specification can be implemented by heterogeneous detection from the mobile terminal 2 of the wireless communication network 2, the mobile terminal 21 can monitor the coexistence related information transmitted by the base station 10 and/or the mobile terminal 1 1 in a broadcast form. In a preferred embodiment, in step S210, the mobile terminal 21 acquires the base station 10 and/or by the heterogeneous wireless communication network 1 through the preamble of the aforementioned coexistence related information on the communication resource block that it wishes to use. Or coexistence related information transmitted by the mobile terminal 11 based on the unified physical layer specification. Then, in step S21 1, the mobile terminal 21 transmits the coexistence related information of the heterogeneous wireless communication network 1 to the base station 20 to which the mobile terminal belongs. The mobile terminal 21 may directly send the received beacon information unit to the base station 20, or may send the valid information to the base station 20. The transmission method can be through an uplink data service packet or a fixed resource block dedicated to transmitting the coexistence information. In step S200, the heterogeneous base station 20 of the wireless communication network 2 also receives the coexistence related information from the heterogeneous wireless communication network 1 of the mobile terminal 21 under its jurisdiction.

Preferably, the base station 10 and/or the mobile terminal 11 of the heterogeneous wireless communication network 1 use it The cognitive resource block in the occupied communication resource transmits the coexistence related information. Then, the base station 20 and/or the mobile terminal 21 acquires the coexistence related information on the cognitive resource block. It can be understood that from the wireless communication network 2, the coexistence related information can be monitored and received by either the base station 20 and the mobile terminal 21, or both, but the base station 20 should acquire the information for subsequent operations.

 As described above, the coexistence related information of the heterogeneous wireless communication network 1 may include information indicating a part of resources used in the communication resources of the heterogeneous wireless communication network 1, and may also include communication resources indicating the heterogeneous wireless communication network 1. Information about a part of the resources that are idle, and/or shared cooperation information of some of the resources that are idle in the communication resources of the heterogeneous wireless communication network 1.

 Then, in step S201, the base station 20 determines the communication resources available from the wireless communication network 2 and coexisting with the heterogeneous wireless communication network 1 based on the coexistence related information of the heterogeneous wireless communication network 1. Preferably, if the coexistence related information is transmitted on the indicated communication resource block, the base station 20 can learn that the communication resource block is occupied, and should avoid using the resource block; if the monitored communication resource block is not received To any coexistence related information, it can be considered that the communication resource block is not occupied, and it can coexist and use. The process of determining the available coexistence resources based on the information of the used partial resources of the primary wireless communication network or the information of the idle partial resources is well known to those skilled in the art, and can be performed with reference to the IEEE 802.22 WRAN network coexistence technology, the present invention I will not repeat them here.

 In addition, in step S200, the base station 20 may also acquire coexistence related information of the same homogeneous wireless communication network as the data service transmission physical layer specification used by the method, for example, IEEE 802.22 WRAN, and then, based on the heterogeneous wireless in step S201 The coexistence related information of the communication network and the coexistence related information of the homogeneous wireless communication network determine the available communication resources coexisting from the wireless communication network and one or more other wireless communication networks.

It can be understood that, in the foregoing embodiment, the coexistence related information sent by the main wireless communication network 1 may be periodic, and the heterogeneous monitoring and acquisition of the coexistence related information sent by the main wireless communication network 1 from the wireless communication network 2 may also be periodic. of. The examples given in the above embodiments are mainly used for coexistence from a wireless communication network 2 with a heterogeneous primary wireless communication network 1. It can be understood that the present invention also has backward compatibility, that is, can also be used for the same layered wireless communication network as the physical layer specification of the data communication transmission of the present wireless communication network. In this case, the coexistence related information received is also used for coexistence with the homogeneous wireless communication network 2, and the unified physical layer specification can also be detected by the wireless communication network 2. The specific implementation method is similar to the foregoing manner of coexistence with the heterogeneous wireless communication network 1, and is not described herein. The above is a detailed description of the application of the present invention in the coexistence of the primary wireless communication network and the wireless communication network. The application of the present invention in a plurality of coexistences from the wireless communication network will be described in detail below.

Flow chart of the method.

 DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS Referring now to Figures 1 and 4, a method for coexisting between a wireless communication network 2 and a slave wireless communication network 3 will be described in detail in accordance with the present invention.

 In step S202, the base station 20 of the wireless communication network 2 determines the communication resources of the slave wireless communication network 2 based on the communication resources that are available from the wireless communication network 2 and coexist with the heterogeneous wireless communication network 1 in step S201. It includes some resources that will be allocated for use and some resources that are idle.

 Next, in step S203, the base station 20 generates coexistence related information of the own slave wireless communication network 2, and the coexistence related information of the slave wireless communication network 2 is used for the slave wireless communication network 2 and other slave wireless communication networks, for example, and Information that the wireless communication network 3 coexists. The generation of the specific coexistence related information may be similar to the steps performed by the base station 10 in the above first embodiment, and details are not described herein.

Then, in step S204, the base station 20 provides the coexistence related information of the present wireless communication network 2 to the mobile terminal 21 under the control of the base station. It should be noted that, for the sake of brevity, the mobile terminal 21 used in the first embodiment is still used as an example, and the general technology in the field It will be understood by those skilled in the art that, when synchronizing with the wireless communication network 3 from the wireless communication network 2, coexistence related information from the wireless communication network 2 can be transmitted using other mobile terminals under its jurisdiction that are close to the wireless communication network 3.

 In step S212, the mobile terminal 21 receives the coexistence related information of the own wireless communication network 2 transmitted by the base station 20. Similar to the above first embodiment, the mobile terminal 21 can also self-acquire coexistence related information indicating its communication resources based on its communication with the base station 20.

 Next, in step S213, the mobile terminal 21 transmits the coexistence related information of the wireless communication network based on a unified physical layer specification, and the unified physical layer specification includes a physical layer that can be detected by the heterogeneous wireless communication network 3. specification. That is, at the beginning of the design of the heterogeneous slave wireless communication network 3, the unified physical layer specification should be supported. It is to be noted that the physical layer specification may be the same as or different from the unified physical layer specification used by the primary wireless communication network 1 in the first embodiment.

 Optionally, in step S204, the base station 20 transmits coexistence related information (not explicitly shown in FIG. 1) of the wireless communication network based on the same unified physical layer specification.

 Similar to the above first embodiment, the coexistence related information may be transmitted by any one of the mobile terminal 21 and the base station 20, or both.

Then, similarly to the wireless communication network 2 in the first embodiment described above, the base station 30 of the wireless communication network 3 acquires the coexistence related information transmitted by the heterogeneous slave wireless communication network 2 based on the unified physical layer specification in step S300. Specifically, the base station 30 may directly monitor the information, or may be sent by the mobile terminal 31 under the control of the base station 30 to the base station 30. The slave wireless communication network 3 can synchronize with the slave wireless communication network 2 based on the coexistence related information it receives. For example, based on the frame header time stamp or the like in the coexistence related information, the base station 30 can synchronize with the wireless communication network 2 according to the frame header time stamp and the frame length of the wireless communication network 2 according to the GPS synchronization principle. In another case, the coexistence related information includes an absolute time such as year, month, day, hour, minute, and second, and the base station 30 can synchronize at that time. Since the length of the timestamp is generally shorter than the absolute time, the use of timestamps can reduce the amount of data transferred. The method of synchronizing between specific wireless communication networks is well known to those skilled in the art, and the present invention will not be described herein. In one case, the coexistence related information includes information of a part of the resources that are free from the communication resources of the wireless communication network 2 and the corresponding shared cooperation in the form of a channel competition related information unit or a channel suspension related information unit. Information, such as an idle subcarrier, frequency or time slot, in step S301, the base station 30 can negotiate with the heterogeneous slave wireless communication network 2 for the idle part of the resources to determine that the slave wireless communication network 3 is available. Communication resources coexisting with the heterogeneous wireless communication network 2.

 Specifically, if the coexistence related information includes the IP address of the base station 20 from the wireless communication network 2, the base station 30 can negotiate with the base station 20 through the backbone network accessed by the base station, so that the air interface can be used to communicate with the base station 20 without using the air interface, thereby saving Wireless communication resources.

 In another case, base station 30 and base station 20 negotiate over the air interface. In this case, the base station 30 also uses a uniform physical layer specification suitable for the communication from the wireless communication network 2 to coexist relevant information, such as a request to temporarily lend a certain idle resource from the wireless communication network 2, to various The form of the information unit is provided to the base station 20. Preferably, the unified physical layer is the same as the unified physical layer specification used from the wireless communication network 2, and they are randomly transmitted in the cognitive resource block to avoid collisions. In another case, the unified physical layer may also be different from the unified physical layer specification used from the wireless communication network 2. The method for coexistence of heterogeneous wireless communication networks according to the present invention has been described in detail above, and the apparatus for coexistence of heterogeneous wireless communication networks and the operation thereof according to the present invention will be described in detail below.

 Third embodiment

FIG. 5 shows a further embodiment of the present invention. In the wireless communication network shown in FIG. 1, the base station 10, the mobile terminal 11 and the base station 20, and the mobile terminal 21 implement the primary wireless communication network 1 and the secondary wireless communication network 2 The block diagram and working process of the device coexisting between. The base station 10 includes means 100 for assisting the heterogeneous wireless communication network 2 to coexist with the present wireless communication network, wherein the first generating device 1000 and the first providing device 1001 are included. The mobile terminal 11 includes means 110 for assisting the heterogeneous wireless communication network 2 to coexist with the present wireless communication network, wherein the first acquisition device 1 100 and the first transmission device 1101 are included. The mobile terminal 21 includes means 210 for coexistence with other heterogeneous wireless communication networks 1, wherein the third acquisition means 2100 is included And the second transmitting device 2101. The base station 20 includes means 200 for coexistence with other heterogeneous wireless communication networks 1, including a second acquisition means 2000 and a second determination means 2001.

 DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS Referring now to Figures 1 and 5, a block diagram and operation of a device for coexistence between a primary wireless communication network 1 and a secondary communication network 2 will be described in detail in accordance with the present invention.

 In general, when the primary wireless communication network allows coexistence from the wireless communication network 2, the base station 10 can instruct the mobile terminal within its jurisdiction to obtain coexistence related information for transmission by an instruction. It will be understood by those skilled in the art that it is not necessary to issue the instruction. For example, the mobile terminal 2 may periodically acquire the coexistence related information and transmit it by itself. Thereafter, the operation according to the present invention performed by the device 110 of the mobile terminal 1 will be as follows.

 First, the first obtaining device 1 100 of the device 10 acquires coexistence related information and a unified physical layer specification, wherein the coexistence related information is information used by the main wireless communication network 1 to coexist with the heterogeneous slave wireless communication network 2, The unified physical layer specification is a physical layer specification that can be detected by heterogeneous detection from the wireless communication network 2.

 For the coexistence related information, on the one hand, it can be generated by the first generating device 1000 of the device 100 of the base station 10 of the primary wireless communication network 1, and transmitted by the first providing device 1001 to the mobile terminal 11. Specifically, the coexistence related information may include the following information:

1. The first generation device 1000 generates, as the coexistence related information, information of the uplink/downlink communication resources that the base station 10 that has been allocated to use communicates with the mobile terminal 11 to transmit to the mobile terminal 1, for example, subcarrier, frequency, A time slot or the like as a beacon that has been occupied by the communication resource. In this way, the other wireless communication network that receives the coexistence related information knows that the communication resource is already occupied by the primary wireless communication network 1, and should avoid using the resource to avoid mutual interference with the primary wireless communication network 1, and better Protect the primary wireless system;

2. The first generation device 1000 generates information of a plurality of communication resources that the base station 10 that has been allocated to use communicates with other devices as coexistence related information, and transmits the information to the mobile terminal 1 1 , for example, has been allocated in the wireless communication network. Each subcarrier, frequency, time slot, etc. in each frame is a beacon that has been occupied by these communication resources. In this way, other wireless communication networks that receive the coexistence related information are aware that the plurality of communication resources are already occupied by the primary wireless communication network 1, and should avoid using the multiple resources to avoid The wireless communication network 1 has mutual interference, better protects the primary wireless system, and can also provide information of multiple occupied resources to other wireless communication networks at one time, reducing the monitoring time of other wireless communication networks;

 3. The first generation device 1000 may further generate, as the coexistence related information, the information of the communication resources of the wireless communication network that has not been allocated the unused partial resources and the shared cooperation information of the idle partial resources, for example, to be sent to the mobile terminal, for example, A certain time slot and subcarrier are still idle, so that other wireless communication networks that receive the coexistence related information can be informed that the part of the resource has not been used yet, and the idle wireless resource can be negotiated with the primary wireless communication network 1 to temporarily lend Use these idle resources in a way that improves spectrum utilization.

 It can be understood that a plurality of the above information may be sent, or may be sent alternatively. For example, in the primary wireless communication network, it merely indicates that the resource is already occupied; and in the secondary communication network, it may further include idle resource information and cooperation information and the like. The coexistence related information is not limited to the above examples, and those skilled in the art can determine appropriate coexistence related information according to the actual network and actual needs, and all information for coexistence with the heterogeneous wireless communication network should be in the present invention. Within the scope of the claims.

 After the first generation device 1000 generates the coexistence related information, the first providing device 1001 provides the coexistence related information to the mobile terminal 11. Preferably, the first providing device 1001 places the Beacon IE in a fixed resource block of the downlink communication resource. Provided to the mobile terminal 1 1; in another case, the first providing device 1001 may also use the data service resource block between the first providing device 1001 and the mobile terminal 11 to form the Beacon IE or the valid information therein in the form of data service. Provided to the mobile terminal. Then, the first acquisition means 1 100 of the mobile terminal 11 receives the coexistence related information from the base station 10.

For the coexistence related information, on the other hand, if the mobile terminal 11 is communicating with the base station 10, it can itself know the uplink/downlink communication resources that have been allocated and used between the mobile terminal and the base station, such as subcarriers, frequencies, and time slots. Wait. Then, the first obtaining device 1 100 itself can generate corresponding coexistence related information according to the communication resource as a beacon that the communication resource has been occupied. In this way, other wireless communication networks that receive the coexistence related information are aware that the communication resource is already occupied by the primary wireless communication network 1, and should be avoided. This resource prevents mutual interference with the primary wireless communication network 1 and better protects the primary wireless system.

 For the unified physical layer specification, in order for each heterogeneous wireless communication network that uses different physical data transmission physical layer specifications to receive coexistence related information issued based on the unified physical layer specification, it is detectable by a heterogeneous wireless communication network. The physical layer specification implemented. For example, it is a waveform different from the waveform used for data traffic transmission of the wireless communication network 1, and the encoding and modulation mode of the bearer data can be demodulated and decoded by a heterogeneous wireless communication communication network; heterogeneous wireless communication The network knows the waveform and can easily detect, demodulate and decode the coexisting related information from the transmitted signal of the wireless communication network 1. In this case, each heterogeneous wireless communication network should be designed to detect the signal of the waveform and perform corresponding demodulation and decoding. It can be understood that designing a physical layer specification that can be detected by a heterogeneous wireless communication network is not a problem of the present invention. Those skilled in the art having knowledge of physical layer specification design such as waveform design can design according to actual needs. A suitable unified physical layer specification is provided to provide the coexistence related information to the heterogeneous infinite communication network, and the present invention will not be described herein. The unified physical layer specification can be fixed in the Subscriber Identity Module (SIM) of the mobile terminal 11 or the mobile terminal user, or negotiated with the base station 11 when the mobile terminal 11 accesses the wireless communication network 1.

 Then, the first transmitting device 1101 of the device 1 10 of the mobile terminal 1 transmits the acquired coexistence related information based on the unified physical layer specification. Preferably, the mobile terminal 11 can use the information element (Information Element, referred to as IE) in the wireless communication system to accommodate the coexistence related information, and the data structure of one such beacon information unit (Beacon IE) can be as shown in the first embodiment. 1 is shown. It will be understood that one of ordinary skill in the art can change the data structure of the beacon information unit accommodating its coexistence related information accordingly according to actual needs.

Preferably, the first transmitting device 1 101 transmits the coexistence related information using the cognitive resource block in the communication resource of the wireless communication network. Specifically, the location of the cognitive resource block can be as shown in FIG. 3. Each superframe includes four frames, wherein the first frame 1 in the superframe includes a preamble (Preamble), and a superframe control header carrying basic system information (Superframe) Control Header (SCH), Frame Control Header (FCH) and Resource Map (MAP) of the current frame, Frame 2, Frame 3 and Frame 4 respectively include the FCH and MAP of the current frame. At the end of the frame 4, a cognitive resource block is drawn, which is specifically used by the mobile terminal 11 to transmit coexistence related information. Specifically, the coexistence related information may be accommodated in a beacon MAC (Media Access Control) payload in the form of a beacon information unit, and together with the beacon MAC header and the CRC (Cyclic Redundancy Check) code constitute a beacon MAC PDU. (protocol data unit); the beacon MAC PDU and the preamble symbol together form a beacon, which is sent by the first transmitting device 1101 based on a unified physical layer specification, wherein the preamble symbol is used to assist the heterogeneous coexistence network to receive the beacon . It is worth noting that in the primary wireless communication network, since it only needs to transmit the beacon without receiving the beacon of other wireless communication systems, the length of the cognitive resource block can be shortened to be the same as the beacon to reduce the system overhead; In the wireless communication network, which will be described hereinafter, since it not only needs to transmit a beacon but also needs to receive beacons sent by other wireless communication networks, the length of the cognitive resource block should be longer to accommodate multiple resources. The flag is transmitted so that the system randomly and cooperatively sends beacons to avoid collision with beacons sent by other networks, and the other locations except the beacons sent by the system are null (Null). The information such as the location, length, and the like of the cognitive resource block may be defined by the base station 10 in the superframe N to which the resource block belongs, or the resource mapping table in the associated frame 3, and provided to each mobile terminal. It is to be noted that, in order to save resources, the base station 10 does not necessarily have to order all mobile terminals under its jurisdiction to issue coexistence related information, but only commands to be transmitted from the mobile terminal 1 in the vicinity of the wireless communication network 2. Then, the mobile terminal that sends the beacon can transmit the coexistence related information according to the other, and the other mobile terminal should keep silent in the cognitive resource block to avoid interference on the propagation of the coexistence related information.

In another case, base station 10 can also issue the coexistence related information (not explicitly shown in Figure 1). Specifically, the first providing device 1001 of the base station 10 and the first sending device 1101 of the foregoing mobile terminal 11 issue coexistence related information, and are based on the unified physical layer specification in the cognitive resource block in the communication resource of the wireless communication network. Send the coexistence related information. It can be understood that the coexistence related information can be transmitted by any one of the mobile terminal 11 and the base station 10, or both. In the above embodiment, the example is mainly used for the coexistence of the primary wireless communication network 1 and a heterogeneous wireless communication network 2, wherein the coexistence related information is used by the wireless communication network 1 for coexistence with the heterogeneous wireless communication network 2. The information, unified physical layer specification is a physical layer specification that can be detected by the base station and the mobile terminal in the heterogeneous wireless communication network 2, including 2. It can be understood that the present invention also has backward compatibility, that is, can also be used for the same layered wireless communication network as the physical layer specification of the data communication transmission of the present wireless communication network. In this case, the coexistence related information is also used to coexist with the homogeneous wireless communication network, and the unified physical layer specification can also be detected by the homogeneous wireless communication network. The specific implementation method is similar to the foregoing manner of coexistence with a heterogeneous wireless communication network, and is not described herein.

 In the above embodiment, the main wireless communication network is exemplified. It can be understood that the above method can also be used from the wireless communication network, and the coexistence related information can be provided to other secondary wireless communication networks to realize coexistence with other secondary wireless communication networks. The coexistence related information may indicate its own communication resources, and may also indicate coexisting communication resources obtained by coexistence with the main network. In the latter case of coexistence, preferably, the base station determines in advance the communication resources available from the wireless communication network and coexisting with the primary wireless communication network, and determines the communication resources of the wireless communication network. For example, a method similar to the WRAN of IEEE 802.22 is used to determine a communication resource that can coexist with the main network by scanning data service communication of the primary network in a channel one by one; it can also be used according to the present invention, as will be described below, Receiving coexistence related information sent by the primary network and then determining a method of coexisting resources, and determining communication resources that can coexist with the primary network.

 After the first transmitting device 101 of the mobile terminal 1 and the first providing device 1001 of the base station 10 issue coexistence related information based on the unified physical layer specification, since the unified physical layer specification can be detected by the heterogeneous wireless communication network 2 That is, the unified physical layer specification should be supported at the beginning of the design of the base station and/or mobile terminal of the heterogeneous slave wireless communication network 2.

Then, the second acquisition device 2000 of the device 200 of the base station 20 acquires the coexistence related information. Specifically, on the one hand, the second obtaining means 2000 monitors the coexistence related information transmitted by the base station 10 and/or the mobile terminal 11 of the heterogeneous wireless communication network 1 in a broadcast manner based on the unified physical layer specification. Preferably, the second obtaining device 2000 is in its desire to make Use the communication resource block to monitor, J.

 On the other hand, since the unified physical layer specification can be implemented by heterogeneous detection from the mobile terminal 2 of the wireless communication network 2, the third obtaining means 2100 of the device 210 of the mobile terminal 21 can also be monitored by the base station 10 and/or The coexistence related information transmitted by the mobile terminal 11 in a broadcast form. In a preferred embodiment, the third obtaining means 2100 acquires the base station 10 of the heterogeneous wireless communication network 1 and/or through the preamble of the aforementioned coexisting related information on the communication resource block that the mobile terminal 21 wishes to use. The mobile terminal 1 1 coexists related information transmitted based on the unified physical layer specification. Then, the second transmitting device 2101 transmits the coexistence related information of the heterogeneous wireless communication network 1 to the base station 20 to which the mobile terminal belongs. The second transmitting device 2101 may directly send the received beacon information unit to the base station 20, and may also send the valid information to the base station 20. The transmission method can be through an uplink data service packet or a fixed resource block dedicated to transmitting coexistence information. Then, the second obtaining means 2000 of the base station 20 receives the coexistence related information of the heterogeneous wireless communication network 1 from the mobile terminal 21 under its jurisdiction.

 Preferably, the base station 10 and/or the mobile terminal 11 of the heterogeneous wireless communication network 1 transmits the coexistence related information using the cognitive resource blocks in the communication resources it occupies. Then, the base station 20 and/or the mobile terminal 21 acquires the coexistence related information on the cognitive resource block. It can be understood that from the wireless communication network 2, the coexistence related information can be monitored and received by either the base station 20 and the mobile terminal 21, or both, but the base station 20 should acquire the information for subsequent operations.

 As described above, the coexistence related information of the heterogeneous wireless communication network 1 may include information indicating a part of resources used in the communication resources of the heterogeneous wireless communication network 1, and may also include communication resources indicating the heterogeneous wireless communication network 1. Information about a part of the resources that are idle, and/or shared cooperation information of some of the resources that are idle in the communication resources of the heterogeneous wireless communication network 1.

Then, the second determining means 2001 of the base station 20 determines the communication resources available from the wireless communication network 2 and coexisting with the heterogeneous wireless communication network 1 based on the coexistence related information of the heterogeneous wireless communication network 1. Preferably, if the coexistence related information is transmitted on the indicated communication resource block, the second determining means 2001 may know that the communication resource block has been occupied. For example, it should avoid using the resource block; if the communication resource block it monitors does not receive any coexistence related information, it can consider that the communication resource block is not occupied, and it can coexist and use. The process of determining available coexistence resources based on information of used partial resources of the primary wireless communication network or information of idle partial resources is well known to those skilled in the art and can be performed with reference to IEEE 802.22 WRAN network coexistence technology, the present invention I will not repeat them here.

 In addition, the second obtaining apparatus 2000 of the base station 20 may also acquire coexistence related information of the isomorphic wireless communication network having the same physical service transmission physical layer specification as that used by the IEEE 802.22 WRAN, and then the second determining apparatus 2001 is different. The coexistence related information of the wireless communication network and the coexistence information of the homogeneous wireless communication network are determined, and the available communication resources coexisting from the wireless communication network and one or more other wireless communication networks are determined.

 It can be understood that, in the foregoing embodiment, the coexistence related information sent by the main wireless communication network 1 may be periodic, and the heterogeneous monitoring and acquisition of the coexistence related information sent by the main wireless communication network 1 from the wireless communication network 2 may also be periodic. of. The examples given in the above embodiments are mainly used for coexistence from a wireless communication network 2 with a heterogeneous primary wireless communication network 1. It can be understood that the present invention also has backward compatibility, that is, can also be used for the same layered wireless communication network as the physical layer specification of the data communication transmission of the present wireless communication network. In this case, the coexistence related information received is also used for coexistence with the homogeneous wireless communication network 2, and the unified physical layer specification can also be detected by the homogeneous wireless communication network 2. The specific implementation method is similar to the foregoing manner of coexistence with the heterogeneous wireless communication network 1, and is not described herein. The application of the present invention in the coexistence of the primary wireless communication network and the wireless communication network has been described in detail above, and the application of the present invention in a plurality of coexistences from the wireless communication network will be described in detail below.

 Fourth embodiment

Based on the above third embodiment, the wireless communication network 2 also coexists with the slave wireless communication network 3. Figure 6 shows a further embodiment of the invention, shown in Figure 1. In the wireless communication network, a block diagram and a working process of the device coexisting between the wireless communication networks 2 and 3 are implemented between the base station 20, the mobile terminal 21, the base station 30, and the mobile terminal 31. The device 200 of the base station 20 further includes a third determining device 2002, a second generating device 2003, and a second providing device 2004 on the basis of the third embodiment. The device 210 of the mobile terminal 21 further includes a fourth obtaining device 2102 and a third transmitting device 2103 on the basis of the third embodiment. The base station 30 includes means 300 for coexistence with other heterogeneous wireless communication networks 2, including a second acquisition device 3000 and a second determination device 3001. The mobile terminal 31 includes means 310 for coexistence with other heterogeneous wireless communication networks 2, including a third obtaining means 3100 and a second transmitting means 3101.

 DETAILED DESCRIPTION OF THE INVENTION Referring now to Figures 1 and 6, a device coexisting between a wireless communication network 2 and a slave wireless communication network 3 and its operation will be described in detail.

 The third determining means 2002 of the device 200 from the base station 20 of the wireless communication network 2 determines the communication resource coexisting with the heterogeneous wireless communication network 1 available from the wireless communication network 2 in accordance with the second determining means 2001, and determines the slave wireless. The communication resources of the communication network 2 include some resources to be allocated for use and some resources that are idle.

 Next, the second generation device 2003 of the base station 20 generates the coexistence related information of the own slave wireless communication network 2, and the coexistence related information of the present slave wireless communication network 2 is used for the slave wireless communication network 2 and other slave wireless communication networks, for example, Information coexisting from the wireless communication network 3. The generation of the specific coexistence related information may be similar to the steps performed by the base station 10 in the above first embodiment, and details are not described herein.

 Then, the second providing means 2004 supplies the coexistence related information of the present wireless communication network 2 to the mobile terminal 21 under the jurisdiction of the base station. It should be noted that, for the sake of brevity, the mobile terminal 21 used in the first embodiment is still used as an example, and those skilled in the art can understand that when synchronizing from the wireless communication network 2 and from the wireless communication network 3, it can be used. Coexistence related information from the wireless communication network 2 is transmitted from other mobile terminals under its jurisdiction.

The fourth obtaining means 2102 of the device 210 of the mobile terminal 21 receives the coexistence related information of the own wireless communication network 2 transmitted by the base station 20. Similar to the above first embodiment, the fourth obtaining means 2102 can also obtain the self-acquisition based on the communication between it and the base station 20. Indicates coexistence related information of its communication resources.

 Then, the third transmitting device 2103 sends the coexistence related information of the wireless IT network based on a unified physical layer specification, and the unified physical layer specification includes a physical layer specification that can be detected by the heterogeneous wireless communication network 3. . That is, the unified physical layer specification should be supported at the beginning of the heterogeneous design of the wireless communication network 3. It is to be noted that the physical layer specification may be the same as or different from the unified physical layer specification used by the primary wireless communication network 1 in the third embodiment.

 Optionally, the second providing device 2004 of the base station 21 also transmits coexistence related information (not explicitly shown in FIG. 1) of the wireless communication network based on the same unified physical layer specification.

 Similar to the above third embodiment, the coexistence related information can be transmitted by any one of the mobile terminal 21 and the base station 20, or both.

 Then, similar to the wireless communication network 2 in the above-described third embodiment, the second acquisition device 3000 of the device 300 of the base station 30 of the wireless communication network 3 acquires the heterogeneous slave wireless communication network 2 based on the unified physical layer specification. The coexistence related information, specifically, on the one hand, the second obtaining device 3000 can directly monitor the information; on the other hand, the coexistence related information sent by the mobile terminal 31 under the control of the base station 30 can also be received. For example, it is received by the third obtaining means 3100 of the device 310 of the mobile terminal 31, and transmitted by its second transmitting means 3101. The slave wireless communication network 3 can synchronize with the slave wireless communication network 2 based on the received coexistence related information. For example, based on the frame header time stamp or the like in the coexistence related information, the base station 30 can synchronize with the wireless communication network 2 according to the frame header time stamp and the frame length of the wireless communication network 2 according to the GPS synchronization principle. In another case, the coexistence related information includes absolute time such as year, month, day, minute, minute, and second, and the base station 30 can synchronize at that time. Since the data length of a timestamp is generally shorter than the absolute time, the use of timestamps can reduce the amount of data transferred. The method of synchronizing between specific wireless communication networks is well known to those of ordinary skill in the art, and the present invention will not be described herein.

In one case, the coexistence related information includes information of a part of the resources that are free from the communication resources of the wireless communication network 2 and the corresponding shared cooperation in the form of a channel competition related information unit or a channel suspension related information unit.
