[0148] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0149] In the prior art, there are communication systems that use the same wireless interface technology in multiple frequency intervals. For example, in the carrier aggregation technology of the Long Term Evolution (LTE) system, a base station is configured with multiple cells with different frequency bands, and the cells in different frequency bands all use LTE technology. The base station can configure multiple cells in different frequency bands as service cells for the UE, and the base station and the UE can simultaneously use the wireless resources of a primary cell and one or more secondary cells for communication.

[0150] For another example, in the bearer separation technology of LTE technology, multiple cells can be configured for the UE as service cells, wherein the multiple cells are from two or more different base stations, and the frequency intervals in which the multiple cells are located may be the same or different. The service cell of the UE includes a primary service cell on the primary base station and secondary service cells of one or more secondary base stations, and the secondary service cell of each secondary base station also includes a primary and secondary cell for the UE to send a physical uplink control channel (PUCCH, Physical uplink control channel) for uplink control information.

[0151] The embodiments of the present invention use the LTE system as the usage scenario.

[0152] In order to better understand the applicable scenarios of the present invention, Figure 1 Provides an application scenario, such as Figure 1 As shown, the user equipment (UE) is located within the coverage of one or more cells or carriers provided by a macro base station or a small base station (Small cell), and the cell serving the UE may be one or more. The UE can be served by the macro cell of the macro base station and the micro cell of the small base station at the same time. When there are multiple service cells for the UE, the UE can operate in carrier aggregation (CA), or dual connectivity (DC, Dual connectivity, the carrier in CA is provided by more than one base station), or coordinated multiple point (CoMP, Coordinated multiple point) transmission mode, and at least one cell in the service cell provides more than one wireless interface technology for the UE.

[0153] However, the applicable scenarios of the present invention are not limited to the case where the UE is covered by multiple cells, but also applicable to the scenario where the UE is only covered by one cell. Furthermore, the present invention is not only applicable to LTE systems, but also to universal mobile telecommunication systems (UMTS), CDMA2000 systems, wireless local area networks (WLAN) systems or future 5G (The fifth generation) wireless communication systems, etc.

[0154] The embodiments of the present invention are described by taking the case where two wireless interface technologies are provided in one cell as an example, and are also applicable to the case where more than two wireless interface technologies are provided in one cell.

[0155] The terms "first", "second", "third" and "fourth" etc. in the specification and claims of the present invention and the above-mentioned drawings are used to distinguish different objects, rather than to describe a specific order. In addition, the terms "including" and "having" and any variations thereof are intended to cover non-exclusive inclusions. For example, a process, method, system, product or device that includes a series of steps or units is not limited to the listed steps or units, but may optionally include steps or units that are not listed, or may optionally include other steps or units that are inherent to these processes, methods, products or devices.

[0165] After reading the cell system broadcast information, the UE may access the wireless network through a random access channel in a public frequency interval, or may access the wireless network through a random access channel in a dedicated frequency interval.

[0166] The dedicated frequency interval is a frequency interval used exclusively by various wireless interface technologies, carrying the wireless resources used for service transmission and responsible for the transmission of specific services. When the network or user initiates a service, the base station establishes the data radio bearer DRB for the service transmission on the dedicated frequency interval or the public frequency interval.

[0167] After the UE accesses the network, the base station shall establish the user's signaling bearer on the public frequency interval or dedicated frequency interval of the cell before establishing the DRB, and transmit the RRC signaling messages between the user and the user through the public frequency interval or dedicated frequency interval. If the user's signaling bearer has been established, the base station does not need to establish the signaling bearer when the UE accesses.

[0168] When the N frequency intervals of a cell include only dedicated frequency intervals, in addition to DRBs, the dedicated frequency intervals also include radio resources carrying common channels and SRBs, where the common channels include: synchronization channels, cell reference signals, broadcast channels, paging channels or random access channels. The user completes initial random access on the random access channel in the dedicated frequency interval.

[0169] When a user initially accesses the network, if the dedicated frequency interval contains a public channel, the user can select the dedicated frequency interval to be used according to the type of service to be initiated, and complete the initial network access on the dedicated frequency interval. In addition, when the user accesses the network, the base station can also establish an SRB on the dedicated frequency interval.

[0170] 202. The base station sends the frequency band information of the N frequency intervals, the correspondence between the N frequency intervals and the wireless interface technology or the characteristic information of the wireless interface technology, and the information of the random access resources of the cell to the UE, and the random access resource information is used for the UE to access the cell or perform uplink synchronization with the cell.

[0171] After the UE is turned on, it can use the synchronization channel of the public frequency interval to obtain system synchronization and maintain synchronization. After obtaining system synchronization, the user can obtain the system broadcast of the cell from the system broadcast message of the public frequency interval, and the system broadcast message may include all public information of the cell. For example, the system broadcast message of the public frequency interval not only includes the frequency band bandwidth of the public frequency interval but also includes the frequency band information of the dedicated frequency interval. Therefore, the user can understand the frequency band information of the dedicated frequency interval in the cell through the system broadcast message of the public frequency interval. The frequency band information includes the bandwidth and center frequency of the dedicated frequency interval; not only includes the correspondence between the public frequency interval and the wireless interface technology, but also includes the correspondence between the dedicated frequency interval and the wireless interface technology; not only includes the random access channel on the public frequency interval, but also includes the random access channel on the dedicated frequency interval; the system information of the public frequency interval may also include relevant feature information of the wireless interface technology supported by the dedicated frequency interval. The system broadcast message of the public frequency interval may also only include cell information related to the public frequency interval, such as only including the frequency band information of the public frequency interval, the correspondence between the public frequency interval and the wireless interface technology, and the random access channel on the public frequency interval. If the system information broadcast in the public frequency interval does not include the frequency band information of the dedicated frequency interval and the relevant feature information of the wireless interface technology supported by the dedicated frequency interval, the base station can configure the frequency band information of the dedicated frequency interval to the UE through RRC signaling after the UE successfully accesses the network from the public frequency interval.

[0172] When the N frequency intervals divided by the base station include only dedicated frequency intervals, the user obtains and maintains system synchronization through the synchronization channel sent on the dedicated frequency interval. The user obtains cell public information through the system information on the dedicated frequency interval, but the dedicated frequency interval can only broadcast cell public information related to the dedicated frequency interval, such as the frequency band information of the dedicated frequency interval, the correspondence between the dedicated frequency interval and the wireless interface technology, and the random access channel on the dedicated frequency interval. The user can also monitor the paging message sent by the base station on the dedicated frequency interval.

[0173] The base station sends the random access channel RACH of the cell to the user through a system broadcast message. The base station can broadcast the RACH information through the system information of the public frequency interval, and the random access resource is located in the public frequency interval, or in a dedicated frequency interval; the base station can also broadcast the RACH information through the system information of the dedicated frequency interval, and the random access resource is located in the dedicated frequency interval.

[0174] 203. The base station maps the service carrying DRB of the UE to at least one frequency interval among the N frequency intervals, wherein each DRB in the DRB corresponds to a frequency interval in the at least one frequency interval, and each frequency interval in the at least one frequency interval corresponds to at least one DRB in the DRB.

[0175] After the UE accesses the network, it may initiate service transmission. The service transmission can be initiated by the network or by the UE. It is necessary to determine the mapping relationship between the DRB used for service transmission and the wireless interface technology for transmitting the service between the base station and the UE. The mapping relationship between the DRB and the wireless interface technology is established by the base station, and the base station sends the mapping relationship to the UE.

[0176] The base station obtains the service type of the service request initiated by the UE, establishes a mapping relationship between the service and the frequency interval according to the service type, and thereby establishes a mapping relationship between the DRB carrying the service and the frequency interval. Since the base station has determined the mapping relationship between the frequency interval and the wireless interface technology in step 201, the corresponding relationship between the service and the DRB carrying the service and the wireless interface technology can also be determined. The DRB corresponds to a dedicated frequency interval or a public frequency interval. The base station may determine the corresponding relationship between the service and the wireless interface technology when the UE initiates the service request, or it may have determined the corresponding relationship between the service and the wireless interface technology before the UE initiates the service request. For each DRB of the UE, the base station specifies the mapped frequency interval. The base station may map all the DRBs of the UE to the same frequency interval or to different frequency intervals. Each DRB can only be mapped to one frequency interval.

[0177] It should be noted that when the UE initially accesses the network, that is, before the base station maps the DRB of the UE to the required frequency interval, the base station needs to establish a signaling bearer SRB for the UE, and map the SRB of the UE to at least one frequency interval among the N frequency intervals, wherein each SRB in the SRB corresponds to a frequency interval in the at least one frequency interval, and each frequency interval in the at least one frequency interval corresponds to at least one SRB in the SRB, and the base station uses the wireless interface technology supported by the frequency interval mapped by the SRB to send wireless resource control RRC signaling to the UE, and the RRC signaling is used to establish the service bearer of the UE.

[0178] When the UE accesses the network, the base station establishes a mapping relationship between the SRB of the UE and the frequency interval. Since the base station has determined the mapping relationship between each frequency interval and the wireless interface technology in step 201, the corresponding relationship between the SRB of the UE and the wireless interface technology can also be determined.

[0179] The base station sends first indication information to the UE, such as RRC signaling, wherein the first indication information is used to indicate the frequency interval to which the SRB of the UE needs to be mapped, or the first indication information is used to indicate the frequency interval to which the SRB of the UE needs to be mapped and the frequency interval to which at least one DRB in the DRB of the UE needs to be mapped.

[0180] If there is no public frequency interval in the frequency interval of the cell, but only a dedicated frequency interval, the base station maps the SRB of the UE to the corresponding dedicated frequency interval. According to the description of the above step 401, it can be understood that in this case, the UE selects a specific dedicated frequency interval to access the network according to the type of service initiated, so the base station maps the SRB of the UE to the dedicated frequency interval selected by the UE. For each SRB of the UE, the base station specifies the frequency interval to be mapped. The base station can map all the SRBs of the UE to the same frequency interval or to different frequency intervals. Each SRB can only be mapped to one frequency interval.

[0181] 204. The base station sends indication information to the UE, where the indication information is used to indicate the frequency interval to which the DRB needs to be mapped.

[0182] After determining the correspondence between the service and the wireless interface technology, the base station sends indication information, such as RRC signaling, to the UE, and informs the UE of the correspondence between the DRB carrying the service and the wireless interface technology through the indication information. The wireless interface technology is the wireless interface technology supported by the frequency range selected by the above-mentioned base station for the service.

[0183] 205. The base station transmits the service carried by the service-bearing DRB to the UE using the wireless interface technology supported by the frequency interval mapped by the DRB.

[0184] The base station uses the frequency interval mapped to each DRB determined in step 203 and the wireless interface technology supported by the frequency interval to transmit the service carried by the DRB with the UE.

[0185] It should be noted that the present invention does not limit the execution order of the above steps. For example, the frequency band information of the N frequency intervals, the correspondence between the N frequency intervals and the wireless interface technology, or the characteristic information of the wireless interface technology can be sent at any time during the execution of the scheme according to different situations.

[0186] As can be seen from the above, a method for using multiple wireless interface technologies provided in Example 1 of the present invention can plan the frequency intervals using each wireless interface technology within the overall frequency range of the cell, and then plan the resources used for common channels, signaling wireless bearers and service bearers in the frequency domain, thereby improving the flexibility of wireless resource configuration and thus improving the efficiency of wireless resource utilization.

[0187] Embodiment 2

[0188] Embodiment 2 of the present invention proposes a method for using wireless interface technology, in order to increase the flexibility of resource configuration of multiple wireless interface technologies, thereby improving the efficiency of wireless resource use.

[0189] As described in the method of Embodiment 1, the base station divides the cell frequency band into N frequency intervals, where N is an integer and N≥2. Each of the N frequency intervals adopts a wireless interface technology, and each cell supports at least two wireless interface technologies. The cell supports at least two different wireless interface technologies, and the different wireless interface technologies refer to wireless interface technologies with different frame structures, or with different multiple access modes, or with different hybrid automatic retransmission request (HARQ, Hybrid automatic retransmission request) loopback delays.

[0190] In the second embodiment of the present invention, the base station divides the cell frequency band into two frequency intervals, and each frequency interval corresponds to a wireless interface technology.

[0191] If the cell provides two different wireless interface technologies. For example, the two wireless interface technologies have different multiple access methods, and the multiple access methods include OFDMA, single carrier frequency division multiple access SC-FDMA, sparse code division multiple access (SCMA, Sparse Code Multiple Access), etc. In some specific feasible implementations, both access technologies can use OFDM modulation technology, but one of the wireless interface technologies is optimized for large-scale machine-to-machine communication (M2M, Machine to machine) services, such as the SCMA method, and the other wireless interface technology uses the OFDM access method of the existing LTE technology. The principle of the SCMA technology is to accommodate more service users under the same time-frequency resources through non-orthogonal expansion and superposition of the code domain, thereby achieving the function of increasing the overall network throughput without affecting the user experience. The SCMA technology is similar to the CDMA technology, and allows multiple codewords to be superimposed and transmitted on a system resource block through frequency domain codeword expansion, thereby increasing the information transmission rate of the multi-carrier system. The frequency domain codewords are superimposed in a manner similar to a low-density parity-check (LDPC) sparse matrix, and the information of the codewords can be decoded by a decoder with lower complexity at the receiving end, thereby restoring the original information.

[0192] For another example, two wireless interface technologies have different frame structures, and the different frame structures are reflected in different frame structure characteristics, including: transmission time interval (TTI), cyclic prefix (CP) length, time length of OFDM symbol, subcarrier spacing, TDD downlink subframe and uplink subframe ratio. In some specific feasible implementations, one of the two wireless interface technologies optimizes ultra-low latency M2M services and uses a TTI length of 0.1ms different from that used by the existing LTE technology; the other wireless interface technology uses the 1ms TTI length of the existing LTE technology.

[0193] For another example, two wireless interfaces have the same frame structure, but the two wireless interfaces use different hybrid automatic repeat request HARQ round trip time (RTT). For example, the HARQ RTT of one wireless interface technology is 4 TTIs in length, and the HARQ RTT of the other wireless interface is 8 TTIs in length.

[0194] For another example, two of the wireless interface technologies are the wireless interface technology for unicast services in the existing LTE wireless interface technology and the wireless interface technology for multimedia broadcast multicast service (MBMS). In order to solve the interference between frequency intervals caused by frequency division of different wireless interface technologies, filtering technology can be used in different frequency intervals, such as filtered OFDM (filtered OFDM) or filter bank multiple carrier (FBMC) or generalized frequency multiplexing (GFDM) and other existing technologies.

[0195] According to the result of network planning, the base station respectively establishes the correspondence between the two frequency intervals and the wireless interface technology, sets the frequency band information of each frequency interval, and sets the characteristic information of the wireless interface technology. Then, the base station sends the frequency band information of the divided frequency intervals, the correspondence between the frequency intervals or the wireless interface technology, and the characteristic information of the wireless interface technology to the UE. The subsequent implementation steps of the base station are consistent with the embodiment and are not repeated here.

[0196] Embodiment 3

[0197] Embodiment 3 of the present invention proposes a method for using wireless interface technology, in order to increase the flexibility of resource configuration of multiple wireless interface technologies, thereby improving the efficiency of wireless resource use.

[0198] As described in the method of Embodiment 1, the base station divides the cell frequency band into N frequency intervals, where N is an integer and N≥2. Each of the N frequency intervals adopts a wireless interface technology, and each cell supports at least two different wireless interface technologies. The different wireless interface technologies refer to wireless interface technologies with different frame structures, or with different multiple access modes, or with different hybrid automatic repeat request HARQ loopback delays.

[0199] The frequency interval planned by the above system includes a public frequency interval and a dedicated frequency interval, or only includes a dedicated frequency interval.

[0200] The common frequency interval is a frequency interval commonly used by the wireless interface technologies supported by the N frequency intervals, including: wireless resources required for common channels, or wireless resources corresponding to common channels and SRBs, wherein common channels include: synchronization channels, cell reference signals, broadcast channels, paging channels, or random access channels. The common frequency interval may also include wireless resources required for DRBs. All UEs in the cell can complete the initial network access-related processes through the common frequency interval.

[0201] The dedicated frequency interval is a frequency interval used exclusively by various wireless interface technologies, carrying the wireless resources used for service transmission, and is responsible for the transmission of specific services. When the network or user initiates a service, the base station establishes the data radio bearer DRB for the service transmission on the dedicated frequency interval or the public frequency interval. The dedicated frequency interval may also include the wireless resources required for SRB.

[0202] Embodiment 3 of the present invention provides a method for configuring the central frequency points of the public frequency interval and the dedicated frequency interval when the N frequency intervals include the public frequency interval and the dedicated frequency interval. There are two configuration methods:

[0203] In the first mode, the center frequency point of the common frequency interval is fixed and located at the center of the cell frequency band. Figure 3-a As shown, the system divides the entire frequency band of the cell into four parts, among which there are three dedicated frequency intervals, and the common frequency interval is located at the center of the entire cell frequency band. In the frequency domain, the three dedicated frequency intervals are located on both sides of the common frequency interval.

[0204] The configuration method can simplify the cell search process and downlink synchronization processing process of the UE. If the system reallocates the resources of the wireless interface technology or the service, the resource position of the dedicated frequency interval corresponding to the wireless interface technology or the service may be changed, thereby changing the position of the wireless interface technology or the service in the cell frequency band, and may cause the frequency band corresponding to the wireless interface technology or the service to be located in multiple locations of the cell frequency band. For example, when the bandwidth of the mobile broadband (MBB) service is reduced after system reconfiguration, the system gives up a part of the frequency band in the cell frequency band to the latency-critical mobile broadband (latency critical MBB) service, then the corresponding frequency band of the latency critical MBB service is located at the original position of the latency critical MBB service and the position originally given up by the MBB, and may be distributed on the left and right sides of the common frequency interval.

[0205] In the second mode, the central frequency point of the common frequency interval is not located at the center of the cell frequency band, and the center position of the common frequency interval is flexibly variable within the cell frequency band. Figure 3-b As shown, the system divides the entire frequency band of the cell into four parts, among which there are three dedicated frequency intervals, and the public frequency interval is not located at the center of the cell frequency band.

[0206] The second configuration method allows the common frequency interval to not be located at the center of the cell bandwidth, which is conducive to the flexible allocation of frequency band resources for different wireless interface technologies or different services. For example, it is conducive to solving the problem that the frequency bands corresponding to the wireless interface technology or the service in the first configuration method are located at multiple locations in the cell frequency band.

[0207] The second configuration method will result in different RF processing processes of the UE from the first configuration method. For example, in the second configuration method, when the UE initially accesses, the transceiver of the UE needs to be first tuned to the center frequency of the common frequency interval to perform a cell search process, synchronization processing, and random access process. When the service is subsequently initiated, the transceiver may be tuned to other frequencies for transceiver; in the first configuration method, when the UE performs the initial access, the transceiver of the UE is tuned to the center frequency of the common frequency interval. Because the center frequency of the common frequency interval is the center frequency of the cell frequency band, when the UE subsequently initiates a service, the center frequency of the transceiver of the UE can be kept unchanged, thereby avoiding RF conversion delay.

[0208] All UEs in the cell can complete wireless network access-related processes through the public frequency range.

[0209] As described in Embodiment 1, the base station sends the frequency band information of the N frequency intervals, the correspondence between the N frequency intervals and the wireless interface technology or the characteristic information of the wireless interface technology, and the information of the random access resource of the cell to the UE. The UE accesses the cell or performs uplink synchronization with the cell through the random access resource information.

[0210] When the UE accesses the network and initiates a service, the base station maps each service bearer DRB of the UE to a designated frequency interval among the multiple frequency intervals, and uses the wireless interface technology supported by the frequency interval to transmit the service to the UE.

[0211] After the UE accesses the network, it may initiate service transmission. The service transmission can be initiated by the network or by the UE. It is necessary to determine the mapping relationship between the DRB used for service transmission and the wireless interface technology for transmitting the service between the base station and the UE. The mapping relationship between the DRB and the wireless interface technology is established by the base station, and the base station sends the mapping relationship to the UE.

[0212] For each DRB of the UE, the base station specifies a mapped frequency interval. The base station can map all DRBs of the UE to the same frequency interval or to different frequency intervals, but one DRB can only be mapped to one frequency interval.

[0213] The correspondence between the service and the wireless interface technology is determined, and the base station informs the UE of the frequency interval required for mapping the DRB carrying the service through designated information, such as RRC signaling. The UE maps the DRB of the service to the frequency interval, and uses the wireless interface technology supported by the frequency interval to transmit the service to the base station.

[0214] Among them, mapping the DRB of the UE to the frequency interval includes: the DRB uses the physical layer resources of the frequency interval; or, the DRB uses the physical layer resources of the frequency interval and the media access control MAC layer entity corresponding to the frequency interval.

[0215] As described in Example 1, if the UE is accessing the network for the first time, the base station should map the SRB of the UE to at least one frequency interval among the N frequency intervals when the UE accesses the wireless network, wherein each SRB in the SRB corresponds to a frequency interval in the at least one frequency interval, and each frequency interval in the at least one frequency interval corresponds to at least one SRB in the SRB, and the base station sends a radio resource control RRC signaling to the UE using the radio interface technology supported by the frequency interval mapped by the SRB, and the RRC signaling is used to establish the service bearer of the UE. For each SRB of the UE, the base station specifies its corresponding frequency interval. The base station can map all the SRBs of the UE to the same frequency interval or to different frequency intervals, but one SRB can only be mapped to one frequency interval.

[0216] The base station first specifies information, such as RRC signaling, to inform the UE of the frequency interval to which the SRB of the UE needs to be mapped, or informs the UE of the frequency interval to which the SRB of the UE needs to be mapped and the frequency interval to which at least one of the DRBs of the UE needs to be mapped. After receiving the RRC signaling, the UE maps the SRB of the UE to the frequency interval, and uses the wireless interface technology supported by the frequency interval to transmit the radio resource control RRC signaling with the base station.

[0217] Among them, mapping the SRB of the UE to the frequency interval includes: the SRB uses the physical layer resources of the frequency interval; or, the SRB uses the physical layer resources of the frequency interval and the media access control MAC layer entity corresponding to the frequency interval.

[0218] Embodiment 4

[0219] Embodiment 4 of the present invention provides a method for using wireless interface technology, including cell frequency band resource division, a frequency band interval indication method corresponding to the wireless interface technology, a UE access system process, a mapping process of the UE's wireless bearer with the wireless interface technology and the frequency interval, and modification of the mapping relationship between the wireless interface technology and the frequency interval.

[0220] like Figure 4-a The method for implementing the fourth embodiment of the present invention may include:

[0221] 411. The base station divides the frequency range of the entire cell into N frequency intervals, each of the N frequency intervals supports one wireless interface technology, the cell supports at least two wireless interface technologies, and N is an integer, and N≥2.

[0222] In this embodiment, the base station divides the entire cell frequency range into two frequency intervals and uses two different wireless interface technologies. One of the wireless interface technologies is the existing LTE technology, corresponding to the public frequency interval, which is used for the transmission of public channels and the user plane of mobile broadband unicast services; the other wireless interface technology uses a frame structure different from the existing technology LTE, and optionally, a different multiple access technology, such as SCMA, or a different HARQ RTT, corresponding to a dedicated frequency interval, for the transmission of ultra-low latency M2M service bearer. In this embodiment, the wireless interface technology supported by the public frequency interval is the LTE wireless interface technology, the LTE wireless interface technology carries the DRB of the mobile broadband unicast service, and the mobile broadband unicast service uses the wireless resources, MAC entity and physical layer (PHY) entity used by the LTE technology; the dedicated frequency interval corresponds to the use of a wireless interface technology different from the LTE technology, and the wireless interface technology different from the LTE technology carries the DRB of the ultra-low latency M2M service, and the DRB of the ultra-low latency M2M service uses the wireless resources, MAC entity and physical layer (PHY) entity used by the wireless interface technology with a frame structure different from the LTE technology.

[0223] In other methods other than the method described in Embodiment 4, the common frequency interval may not transmit services, and the frequency interval used by the common channel may be a separate frequency interval. For example, the frequency range of the cell is divided into three frequency intervals, the common frequency interval uses an independent wireless interface technology, and the mobile broadband unicast service and the ultra-low latency M2M service use a wireless interface technology respectively. Figure 4-b In the system shown, three SRBs in the control plane are mapped to a radio interface technology that is different from the radio interface technology to which the services are mapped.

[0224] 412. The base station sends the frequency band information of the N frequency intervals, the correspondence between the N frequency intervals and the wireless interface technology or the characteristic information of the wireless interface technology, and the information of the random access resources of the cell to the UE, and the random access resource information is used for the UE to access the cell or perform uplink synchronization with the cell.

[0225] The base station may inform the UE of the correspondence between each frequency interval and the wireless interface technology or the characteristic information of the wireless interface technology in the following manner:

[0226] The base station sends a system broadcast message to inform the UE of the correspondence between each frequency interval and the wireless interface technology or the characteristic information of the wireless interface technology; or,

[0227] The base station sends an RRC signaling message to inform the UE of the correspondence between each frequency interval and the radio interface technology or the characteristic information of the radio interface technology; or,

[0228] The base station sends the control unit CE of the media access control MAC to inform the UE of the correspondence between each frequency interval and the wireless interface technology or the characteristic information of the wireless interface technology; or, the base station sends the physical downlink control channel PDCCH to inform the UE of the correspondence between each frequency interval and the wireless interface technology or the characteristic information of the wireless interface technology.

[0229] This fourth embodiment provides an example of the content of a system message broadcast in a common frequency interval. The base station can inform the UE of the frequency band information of each frequency interval, the correspondence between each frequency interval and the wireless interface technology, and the characteristic information of the wireless interface technology supported by the dedicated frequency interval through the broadcast message of the common frequency interval, including: the type of wireless interface technology, including the combination characteristics of multiple access mode, frame structure, CP length, physical channel, etc.; uplink and downlink subframe configuration; physical channel resource configuration information specific to the wireless interface. In this embodiment, the system information of the common frequency interval includes:

[0230] The master information block (MIB) of the public frequency area includes: the system frame number (SFN) of the public frequency interval; the dedicated frequency interval uses the same SFN, or an integer multiple relationship with the SFN of the public frequency interval; the bandwidth of the public frequency interval.

[0231] The newly added information elements of the system information block 1 (SIB1) of the public frequency zone include: the identifier of the wireless interface technology supported by the public frequency interval; the downlink bandwidth, sub-band starting offset frequency or center frequency of the dedicated frequency interval, the identifier of the wireless interface technology supported by the dedicated frequency interval, the type of wireless interface technology, including combined characteristics such as multiple access mode, frame structure, CP length, physical channel, etc.; for the TDD system, it also includes the uplink and downlink subframe configurations of the dedicated frequency interval.

[0232] The system information block 2 (SIB2) of the common frequency area includes but is not limited to: PRACH resource configuration of the radio interface technology supported by the common frequency interval; for frequency division multiplexing (FDD) systems, uplink bandwidth; physical layer resource configuration information specific to the radio interface, such as SCMA-related configuration information. For FDD systems, the uplink bandwidth used by each radio interface technology contained in the system information block 2 may be different from the downlink bandwidth.

[0233] After the base station notifies the UE of the correspondence between each frequency interval and the wireless interface technology or the characteristic information of the wireless interface technology, the UE can select the corresponding frequency interval to complete the wireless network access process according to the type of the initiated service.

[0234] The base station sends the random access channel RACH of the cell to the user through a system broadcast message. The base station can broadcast the RACH information in the system information of the public frequency interval. The random access resource can be located in the public frequency interval or in the dedicated frequency interval. The base station can also broadcast the RACH information in the system information of the dedicated frequency interval. The random access resource is located in the dedicated frequency interval.

[0235] The UE obtains RACH resource configuration information through the system information of the public frequency interval, including the time-frequency domain resources of the RACH channel and the RACH public resource configuration information. The RACH resource configuration can be located in the public frequency interval and / or the dedicated frequency interval. The UE performs the random access process according to the random access resource selected by itself.

[0236] The RACH resources on each frequency interval are configured according to the characteristics of the wireless interface technology supported by each frequency interval. Specifically, the format of the RACH channel, the random access preamble configuration, etc. are configured according to the characteristics of the wireless interface technology on each frequency interval. For example, the RACH resources on the dedicated frequency interval are configured according to the frame structure used by the wireless interface technology of ultra-low latency M2M.

[0237] 413. The base station maps the service carrying DRB of the UE to at least one frequency interval among the N frequency intervals, wherein each DRB in the DRB corresponds to a frequency interval in the at least one frequency interval, and each frequency interval in the at least one frequency interval corresponds to at least one DRB in the DRB.

[0238] 414. The base station sends indication information to the UE, where the indication information is used to indicate the frequency interval to which the DRB needs to be mapped.

[0239] The base station informs the UE of the frequency interval required for mapping the DRB carrying the service through the RRC signaling.

[0240] The base station can send an RRCConnectionReconfiguration message to the UE to configure the mapping relationship between the data radio bearer (DRB) and the wireless interface technology. The DRB is mapped to the MAC layer and the physical layer of the corresponding wireless interface technology. For example, the DRB of the ultra-low latency M2M service is mapped to the wireless interface technology corresponding to the ultra-low latency M2M, and the DRB of the mobile broadband unicast service is mapped to the wireless interface technology of the LTE technology.

[0241] Figure 4-c An example of the mapping relationship between DRB and wireless interface technology is given. DRB1 and DRB2 use wireless interface technology 1, corresponding to a frequency interval in the cell, and use the wireless resources, MAC entity and PHY entity of wireless interface technology 1; DRB3 uses wireless interface technology 2 which is different from DRB1 and DRB2, corresponding to another frequency interval in the cell, and uses the wireless resources, MAC entity and PHY entity of wireless interface technology 2. In this embodiment, the wireless interface technology 1 is LTE wireless interface technology, and the wireless interface technology 2 is machine to machine (M2M) wireless interface technology; or the wireless interface technology 1 is M2M wireless interface technology, and the wireless interface technology 2 is LTE wireless interface technology.

[0242] It should be noted that if the UE accesses the network for the first time, before the base station establishes the DRB, the base station maps the SRB of the UE to at least one frequency interval among the N frequency intervals, wherein each SRB in the SRB corresponds to a frequency interval in the at least one frequency interval, and each frequency interval in the at least one frequency interval corresponds to at least one SRB in the SRB, and the base station uses the wireless interface technology supported by the frequency interval to transmit wireless resource control RRC signaling with the UE, and the RRC signaling is used to establish the service bearer of the UE.

[0243] In the prior art, the signaling radio bearer includes three SRBs, SRB0, SRB1 and SRB2, which are used to transmit different control signaling. SRB0 mapped to the common control logical channel (CCCH) is used to transmit control signaling before establishing a dedicated control logical channel (dedicated control channel), and SRB1 and SRB2 mapped to the dedicated control logical channel (dedicated control channel) are used to transmit dedicated control signaling of the UE.

[0244] The base station sends RRC signaling to the UE to indicate the frequency interval to which the SRB is to be mapped.

[0245] Specifically, when the UE initially accesses the cell, the UE sends a radio resource control connection request (RRCConnectionRequest) message to the base station through SRB0. The message is sent to the base station in message 3 of the random access process. The base station responds to the message from the UE and sends a radio resource control connection establishment (RRCConnectionSetup) message to the UE through SRB0. The base station indicates the frequency interval required to be mapped to SRB1 in the message. After the UE successfully establishes SRB1, it sends a radio resource control connection establishment completion (RRCConnectionSetupComplete) message to the base station through SRB1. The base station sends a radio resource control connection reconfiguration (RRCConnectionReconfiguration) message to the UE through SRB1 to configure SRB2 and service bearer DRB for the UE. The frequency interval required to be mapped to SRB2 and service bearer DRB is indicated in the message.

[0246] If the UE switches to the target cell, the target base station sends the random access resource information and the frequency interval information required for mapping SRB1, SRB2, and DRB to the source base station. The source base station sends a wireless resource control connection reconfiguration message carrying mobility control information to the UE, and sends the above configuration information of the target base station to the UE.

[0247] If it is in a bearer separation system, the radio resource control connection reconfiguration message sent by the base station to the UE may include the frequency interval required for mapping the DRB on the secondary cell SCell, and the radio resource control connection reconfiguration message is sent to the UE via SRB1 on the primary cell PCell. The radio resource control connection reconfiguration message also includes the frequency interval information of SRB1 or SRB2 on the secondary cell SCell on the SCell.

[0248] When the UE accesses the network, the base station establishes the frequency intervals required for mapping the above three SRBs. Optionally, the base station maps all three SRBs of the UE to a common frequency interval.

[0249] The base station informs the UE of the correspondence between the SRB of the UE and the wireless interface technology through an RRC signaling message, and the wireless interface technology is the wireless interface technology supported by the frequency interval selected by the base station according to the above steps. In this embodiment, the base station may send a wireless connection establishment (RRCConnectionSetup) message to the UE to configure the frequency interval required for mapping the signaling wireless bearer SRB1. Map SRB1 and the MAC layer and physical layer of the corresponding wireless interface technology, that is, map SRB1 and the MAC layer and physical layer of the LTE technology. The base station may send a wireless connection connection reconfiguration (RRCConnectionSetup) message to the UE to configure the frequency interval required for mapping the signaling wireless bearer SRB2. Map SRB2 and the MAC layer and physical layer of the corresponding wireless interface technology, that is, map SRB2 and the MAC layer and physical layer of the LTE technology.

[0250] Optionally, the RRC reconfiguration signaling indicates the wireless interface technology used by the UE's service and the frequency range corresponding to the wireless interface technology, specifically, the frequency range required for mapping DRB and the frequency range required for mapping SRB2.

[0251] The new information elements added to the RRC connection reconfiguration message include but are not limited to:

[0252] The wireless interface technology addition / modification list information element includes the corresponding identification of the wireless interface technology and the wireless interface technology type (including the combination characteristics of multiple access mode, frame structure, CP length, physical channel, etc.);

[0253] Downlink bandwidth, sub-band start offset frequency or center frequency of the dedicated frequency interval;

[0254] For TDD systems, it also includes uplink and downlink subframe configurations in dedicated frequency intervals;

[0255] The radio interface technology release list information element at least includes identification information corresponding to the radio interface technology.

[0256] The add / modify list information element includes the DRB and the frequency interval required for mapping, and the frequency interval required for mapping of SRB.

[0257] Different wireless interface technologies may be used to communicate between the base station and the UE. The wireless interface technologies are used for different services and use corresponding wireless resources. It is understandable that different UEs may use different wireless interface technologies.

[0258] 414. The base station transmits the service carried by the service-bearing DRB to the UE using the wireless interface technology supported by the frequency interval mapped by the DRB.

[0259] The base station uses the frequency interval mapped to each DRB determined in step 413 and the wireless interface technology supported by the frequency interval to transmit the service carried by the DRB with the UE.

[0260] 415. When the cell load situation changes, or the demand for wireless resources of the UE service changes, the base station changes the bandwidth corresponding to the wireless interface technology, or changes the frequency range corresponding to the wireless interface technology.

[0261] The base station indicates the bandwidth change corresponding to the wireless interface technology, or the new bandwidth and the new frequency range to the UE through a system message, or RRC signaling, or a MAC control element (CE, control element), or a physical downlink control channel (PDCCH, physical downlink control channel).

[0262] For example, when the M2M service load increases and more bandwidth is required, the base station increases the bandwidth used by the radio interface technology used by the M2M service and reconfigures the bandwidth corresponding to each radio interface technology.

[0263] Change the frequency intervals corresponding to different wireless interface technologies. For example, if the wireless conditions of most UEs using ultra-low latency M2M services are better in another frequency interval, the base station notifies the change of the frequency intervals corresponding to different wireless interface technologies in the above manner.

[0264] Changing the frequency interval corresponding to the wireless interface technology also includes adding or deleting the wireless interface technology and the corresponding frequency interval, and the UE can be notified through RRC signaling or system information.

[0265] Through the above steps, those skilled in the art can easily understand that the correspondence between the wireless interface technology and the frequency range can be flexibly changed.

[0266] Embodiment 5

[0267] Embodiment 5 of the present invention provides another implementation method of a method using wireless interface technology, including cell frequency band resource division, a frequency band interval indication method corresponding to the wireless interface technology, a UE access system process, and a mapping process of the UE's wireless bearer with the wireless interface technology and the frequency interval.

[0268] In the fifth embodiment, the entire cell frequency band is divided into two frequency intervals, but the configuration of the public frequency interval in the fourth embodiment is different from that in the fourth embodiment. In the present embodiment, the two frequency intervals are dedicated frequency intervals, supporting different wireless interface technologies. At the same time, the public frequency interval covers the entire frequency band of the cell.

[0269] The steps of the implementation method of the fifth embodiment may include:

[0270] The base station divides the frequency range of the entire cell into two dedicated frequency intervals, and each frequency interval uses a different wireless interface technology. The wireless interface technology used in one of the frequency intervals is the existing LTE technology, which is used for the transmission of mobile broadband unicast services; the wireless interface technology used in the other frequency interval is the transmission of ultra-low latency M2M services, using a frame structure different from the existing technology LTE, and optionally, using different multiple access technologies, such as SCMA. In this embodiment, the public frequency interval occupies the entire frequency band of the cell, using LTE wireless interface technology, and the public frequency interval carries the public channels of the cell, which include: synchronization channel, cell reference signal, broadcast channel, paging channel and random access channel.

[0271] It is understandable to those skilled in the art that, in this embodiment, the common frequency interval and the dedicated frequency resources overlap with each other in the frequency domain, so the cell common channel is also mapped to the dedicated frequency interval in the frequency domain, but the common channel will be distinguished from the DRB carried by the dedicated frequency interval in other dimensions, such as in the time domain.

[0272] The system information on the common frequency interval, that is, the system information broadcast on the total bandwidth of the cell, may include the following:

[0273] The master information block (MIB) of the public frequency area includes: the system frame number (SFN) of the cell; and the total downlink bandwidth of the cell.

[0274] The newly added information elements of the system information block 1 (SIB1) in the public frequency area include but are not limited to: an identifier corresponding to the wireless interface technology contained in the current cell, and frequency band information of the dedicated frequency interval; wireless interface technology features supported by the dedicated frequency interval, including: wireless interface technology type, including combined features such as multiple access mode, frame structure, CP length, physical channel, and for the TDD system, also including the uplink and downlink subframe configurations of the dedicated frequency interval; the downlink bandwidth of the dedicated frequency interval, the subband starting offset frequency or the center frequency.

[0275] The system information block 2 (SIB2) of the common frequency area includes but is not limited to: RACH resource configuration of the radio interface technology supported by the common frequency interval; for the frequency division multiplexing (FDD) system, it includes uplink bandwidth; specific physical resource configuration information of the radio interface technology supported by the dedicated frequency interval, such as SCMA-related configuration information. For FDD systems, the uplink bandwidth used by each radio interface technology contained in the system information block 2 may be different from the downlink bandwidth.

[0276] The base station sends the random access channel RACH of the cell to the user through a system broadcast message. In this embodiment, the base station broadcasts RACH information in the system information of the public frequency interval. The random access resource may be located within the entire frequency band of the cell.

[0277] The UE obtains the frequency band information of the public frequency interval and the dedicated frequency interval, the correspondence between the dedicated frequency interval and the wireless interface technology or the characteristic information of the wireless interface technology, and the RACH resource configuration information of the cell through the system information of the public frequency interval, and the RACH resource configuration information includes the time-frequency domain resources of the RACH and the RACH public resource configuration information. The UE selects a RACH resource from the received RACH resource configuration, and performs a random access process according to the RACH resource selected by itself.

[0278] The steps for the UE to perform random access and establish DRB are consistent with those in Example 4 and will not be repeated here.

[0279] It is worth noting that if the UE is accessing the network for the first time, the base station should first establish an SRB for the UE before establishing a DRB for the UE, map the UE's signaling bearer SRB to a designated frequency interval, and use the wireless interface technology supported by the designated frequency interval to transmit the radio resource control RRC signaling with the UE. In this embodiment, the designated frequency interval is a public frequency interval, which occupies the entire frequency band of the cell in the frequency domain; or it can also be a dedicated frequency interval.

[0280] The base station sends first indication information, such as RRC signaling, to the UE, to indicate the frequency interval to which the SRB needs to be mapped.

[0281] Embodiment 6

[0282] This embodiment 6 provides an access method using wireless interface technology implemented on the terminal side to cooperate with the implementation of wireless interface technology on the base station side. Figure 5As shown, the base station divides the cell frequency band into N frequency intervals, each of the N frequency intervals supports a wireless interface technology, N is an integer, and N≥2, and the process of the terminal device accessing the wireless network is as follows:

[0283] 501. User equipment UE receives frequency band information of the N frequency intervals, correspondence between the N frequency intervals and wireless interface technologies or feature information of the wireless interface technologies, and random access resource information of the cell sent by a base station.

[0284] When the system is doing network planning, the frequency band of the entire cell can be divided into N frequency intervals, and each of the N frequency intervals uses a wireless interface technology, and the cell supports at least two different wireless interface technologies. The base station establishes a corresponding relationship between each frequency interval and the wireless interface technology according to the result of network planning. Then, the base station sends the frequency band information of the divided frequency band interval, the corresponding relationship between the frequency interval and the wireless interface technology, or the characteristic information of the wireless interface technology to the UE.

[0285] The frequency interval planned by the above system includes a public frequency interval and a dedicated frequency interval, or only includes a dedicated frequency interval.

[0286] Among them, the common frequency range is a frequency range commonly used by various wireless interface technologies, including: wireless resources corresponding to common channels and SRBs, wherein the common channels include: synchronization channels, cell reference signals, broadcast channels, paging channels or random access channels.

[0287] All users in the cell can complete the initial network access-related processes through the common frequency interval:

[0288] After turning on the phone, the user can use the synchronization channel of the public frequency interval to obtain system synchronization and maintain synchronization. After obtaining system synchronization, the user can obtain the system broadcast of the cell from the system broadcast message of the public frequency interval, and the system broadcast message includes all public information of the cell. For example, the system broadcast message of the public frequency interval not only includes the frequency band bandwidth of the public frequency interval but also includes the frequency band information of the dedicated frequency interval. Therefore, the user can understand the frequency band information of the dedicated frequency interval in the cell through the system broadcast message of the public frequency interval. The frequency band information includes the bandwidth and center frequency of the dedicated frequency interval; not only includes the correspondence between the public frequency interval and the wireless interface technology, but also includes the correspondence between the dedicated frequency interval and the wireless interface technology; not only includes the random access channel on the public frequency interval, but also includes the random access channel on the dedicated frequency interval; the system information of the public frequency interval may also include the relevant feature information of the wireless interface technology supported by the dedicated frequency interval. The system broadcast message of the public frequency interval may also only include the cell information related to the public frequency interval, such as only including the frequency band information of the public frequency interval, the correspondence between the public frequency interval and the wireless interface technology, and the random access channel on the public frequency interval. If the system information broadcast in the public frequency interval does not include the frequency band information of the dedicated frequency interval and the relevant feature information of the wireless interface technology supported by the dedicated frequency interval, the base station can configure the frequency band information of the dedicated frequency interval to the UE through RRC signaling after the UE successfully accesses the network from the public frequency interval.

[0289] Users can receive the frequency band information of each frequency interval sent by the base station in the following two ways:

[0290] a system broadcast message or RRC control signaling on a common frequency interval sent by the base station read by the user, wherein the system broadcast message or RRC control signaling on the common frequency interval includes frequency band information of the common frequency interval and frequency band information of the dedicated frequency interval; or

[0291] The user reads the system broadcast message or RRC control signaling on the dedicated frequency interval sent by the base station, and the system broadcast message or RRC control signaling on the dedicated frequency interval includes the frequency band information of the dedicated frequency interval.

[0292] Users can also receive system paging messages through the paging channel in the public frequency interval.

[0293] After the user reads the cell system broadcast information, he can access the wireless network through the random access channel in the public frequency interval, or through the random access channel in the dedicated frequency interval. When the user accesses the network, the base station establishes the user's signaling bearer in the cell's public frequency interval and transmits the RRC signaling message between the user and the base station through the public frequency interval. If the user's signaling bearer has been established, the base station does not need to establish a signaling bearer for the UE.

[0294] The dedicated frequency interval is a frequency interval used exclusively by various wireless interface technologies, which carries the wireless resources used for service transmission and is responsible for the transmission of specific services. After the user completes the initial access in the public frequency interval, when the network or user initiates a service, the base station will establish the data radio bearer DRB for the service transmission on the dedicated frequency interval.

[0295] It is worth noting that the public frequency interval can be used exclusively to carry public channels and SRBs, or it can be used to transmit specific services like a dedicated frequency interval. Such a public frequency interval can carry public channels, SRBs, and DRBs at the same time.

[0296] Before the UE reads the system broadcast message, it can complete and maintain synchronization with the system through the synchronization channel of the public frequency interval; or, when the base station sends a synchronization signal and a reference signal in a dedicated frequency interval, the UE completes initial synchronization with the system through the synchronization channel of the public frequency interval and then maintains synchronization with the system through the synchronization channel or reference signal of the dedicated frequency interval. However, if there is no public frequency interval, before the UE reads the system broadcast message in the dedicated frequency interval, it completes and maintains synchronization with the system through the synchronization channel sent on the dedicated frequency interval.

[0297] In addition, if there is no public frequency interval in the system, the dedicated frequency interval also carries public channels and SRBs, where the public channels include: synchronization channels, cell reference signals, broadcast channels, paging channels or random access channels. Users can obtain and maintain system synchronization through the synchronization channel sent on the dedicated frequency interval. The user obtains cell public information from the system information on the dedicated frequency interval, but the dedicated frequency interval can only broadcast cell public information related to the dedicated frequency interval, such as the frequency band information of the dedicated frequency interval, the correspondence between the dedicated frequency interval and the wireless interface technology, and the random access channel on the dedicated frequency interval. The user monitors the paging message sent by the base station on the dedicated frequency interval and completes the initial random access on the random access channel on the dedicated frequency interval. When the user initially accesses the network, the user can select the dedicated frequency interval to be used according to the type of service to be initiated, and complete the initial network access on the dedicated frequency interval. In addition, when the user accesses the network, the base station can also establish SRB on the dedicated frequency interval.

[0298] The base station sends the random access channel RACH of the cell to the user through a system broadcast message. The base station can broadcast the RACH information in the system information of the public frequency interval. The random access resource can be located in the public frequency interval or in the dedicated frequency interval. The base station can also broadcast the RACH information in the system information of the dedicated frequency interval. The random access resource is located in the dedicated frequency interval, that is, the RACH resource read by the UE on the system information of the dedicated frequency interval is located in the dedicated frequency interval.

[0299] 502. The UE accesses a wireless network or performs uplink synchronization on the cell random access resources sent by the base station.

[0300] The UE selects a random access channel according to the RACH resource information in the system broadcast of the base station.

[0301] If the UE is accessing the network for the first time, the UE uses the selected random access channel to access the network; if the UE is not accessing the network for the first time, the UE may use the selected random access channel to perform uplink synchronization.

[0302] 503. The UE receives indication information sent by the base station, where the indication information is used to indicate the frequency interval to which the DRB of the UE needs to be mapped.

[0303] When the UE accesses the network and initiates a service, the base station maps the service bearer DRB of the UE to a frequency interval specified by the base station, and uses the wireless interface technology supported by the specified frequency interval to transmit the service to the UE.

[0304] After the UE accesses the network, it may initiate service transmission. The service transmission can be initiated by the network or by the UE. It is necessary to determine the mapping relationship between the DRB used for service transmission and the wireless interface technology for transmitting the service between the base station and the UE. The mapping relationship between the DRB and the wireless interface technology is established by the base station, and the base station sends the mapping relationship to the UE.

[0305] The base station obtains the service type of the service request initiated by the UE, and establishes a mapping relationship between the service and the frequency interval according to the service type. Since the mapping relationship between each frequency interval and the wireless interface technology has been determined in the base station, the corresponding relationship between the service and the wireless interface technology can also be determined, so that the mapping relationship between the DRB carrying the service and the wireless interface technology can also be determined. The DRB may be mapped to a dedicated frequency interval or to a public frequency interval. The base station may determine the corresponding relationship between the service and the wireless interface technology when the UE initiates the service request, or it may have determined the corresponding relationship between the service and the wireless interface technology before the UE initiates the service request.

[0306] The base station informs the UE of the frequency interval required to be mapped by the DRB carrying the service through indication information, such as RRC signaling. The UE then learns the radio interface technology used by the DRB through the radio interface technology supported by the frequency interval learned previously.

[0307] It is worth noting that if the UE accesses the network for the first time, the base station needs to establish an SRB for the UE before establishing a DRB for the UE. The base station establishes a mapping relationship between the UE's SRB and the frequency interval. Since the base station has determined the mapping relationship between each frequency interval and the wireless interface technology in the above steps, the correspondence between the UE's SRB and the wireless interface technology can also be determined.

[0308] The UE maps the signaling radio bearer SRB of the UE to the designated frequency interval according to the instruction of the base station, and transmits radio resource control RRC signaling with the base station using the radio interface technology supported by the frequency interval, wherein the RRC signaling is used to establish the service bearer of the UE.

[0309] When the system broadcast message read by the UE is the system broadcast information of the public frequency interval, the UE accesses the wireless network from the public frequency interval, and the base station can map the UE's SRB to the public frequency interval or the dedicated frequency interval. If there is no public frequency interval in the frequency interval of the cell, but only a dedicated frequency interval, the system broadcast information read by the UE is the system broadcast information of the dedicated frequency interval, and the dedicated frequency interval contains public channels and signaling bearer resources. The UE accesses the wireless network from the dedicated frequency interval, and the base station maps the UE's SRB to the corresponding dedicated frequency interval. According to the description of the above steps, it can be understood that in this case, the UE selects a specific dedicated frequency interval to access the network according to the type of service initiated, so the base station maps the UE's SRB to the dedicated frequency interval selected by the UE. The public channels include: synchronization channel, cell reference signal, broadcast channel, paging channel or random access channel.

[0310] The base station informs the UE of the frequency interval required to be mapped for the SRB of the UE through an RRC signaling message, or informs the UE of the frequency interval required to be mapped for the SRB and the frequency interval required to be mapped for at least one of the DRBs of the UE. After receiving the RRC signaling, the UE maps the signaling radio bearer SRB of the UE to the specified frequency interval, and uses the wireless interface technology supported by the frequency interval to transmit the radio resource control RRC signaling with the base station.

[0311] Among them, mapping the SRB of the UE to the frequency interval includes: the SRB uses the physical layer resources of the frequency interval; or, the SRB uses the physical layer resources of the frequency interval and the media access control MAC layer entity corresponding to the frequency interval.

[0312] 504. The UE maps the DRB of the UE to the frequency interval required by the DRB.

[0313] The UE maps the DRB to a specified frequency interval, including: the DRB uses the physical layer resources of the frequency interval; or, the DRB uses the physical layer resources of the frequency interval and the media access control MAC layer entity corresponding to the frequency interval.

[0314] 505. The UE uses the wireless interface technology supported by the frequency interval mapped by the DRB to transmit the service carried by the service-bearing DRB with the base station.

[0315] The UE uses the frequency interval mapped to each DRB determined in step 503 and the wireless interface technology supported by the frequency interval to transmit the service carried by the DRB with the base station.

[0316] It can be seen from the above that according to a method of using wireless interface technology provided in embodiment six of the present invention, the frequency intervals using each wireless interface technology can be planned within the overall frequency range of the cell, and then the resources used for common channels, signaling wireless bearers and service bearers can be planned in the frequency domain, thereby improving the flexibility of wireless resource configuration and thus improving the efficiency of wireless resource utilization.

[0317] Embodiment 7

[0318] This embodiment 7 provides a specific implementation method of implementing an access method using wireless interface technology on the terminal side, so as to cooperate with the method using wireless interface technology on the base station side proposed in the present invention.

[0319] like Figure 6-a The figure shows a schematic diagram of a terminal accessing a wireless network provided by Embodiment 7 of the present invention, wherein a common channel and an SRB are mapped to the common frequency interval, the UE accesses the wireless network through the common frequency interval, the DRB is mapped to the dedicated frequency interval, and the UE transmits services through the dedicated frequency interval. Among them, service A is transmitted using dedicated frequency interval 1, and service B is transmitted using dedicated frequency interval 2.

[0320] When the system does network planning, the frequency band of the entire cell is divided into N frequency intervals, and each frequency interval is specified to use a different wireless interface technology. In this embodiment, the frequency range of the entire cell is divided into two frequency intervals, and two different wireless interface technologies are used. One of the wireless interface technologies is the existing LTE technology, corresponding to the public frequency interval, which is used for the transmission of public channels and mobile broadband unicast services; the other wireless interface technology uses a frame structure different from the existing technology LTE. Optionally, different multiple access technologies, such as SCMA, can also be used, corresponding to dedicated frequency intervals, for the transmission of ultra-low latency M2M services. In this embodiment seven, the wireless interface technology supported by the public frequency interval is the LTE wireless interface technology, the LTE wireless interface technology carries the DRB of the mobile broadband unicast service, and the mobile broadband unicast service uses the wireless resources, MAC entity and physical layer (PHY) entity used by the LTE technology; the dedicated frequency interval corresponds to a wireless interface technology that uses a frame structure different from that of the LTE technology, and the wireless interface technology carries the DRB of the ultra-low latency M2M service, and the DRB of the ultra-low latency M2M service uses the wireless resources, MAC entity and physical layer (PHY) entity used by the wireless interface technology that has a frame structure different from that of the LTE technology.

[0321] In the seventh embodiment, all UEs detect common channels such as synchronization channel (SCH) and broadcast channel BCH from a common frequency interval, and access the system according to random access resources indicated by a system message. The random access resources are located in a common frequency interval, or in a dedicated frequency interval, or in both a common frequency interval and a dedicated frequency interval. The UE can select different random access resources to access the wireless network, or access the wireless network according to the random access resources indicated by the base station.

[0322] like Figure 6-b The implementation method of this embodiment may include:

[0323] 601. User equipment UE detects a synchronization channel in a common frequency interval to obtain and maintain system synchronization.

[0324] The UE detects the synchronization channel at the frequency point of the common frequency interval according to the stored frequency point of the common frequency interval, obtains the synchronization channel information by using the synchronization channel detection method in the prior art LTE, and achieves downlink synchronization with the base station.

[0325] In the case where the wireless interface technology corresponding to the dedicated frequency area also provides a synchronization channel or a reference signal for precise synchronization, the UE can obtain the frequency band information of the dedicated frequency interval by reading the system broadcast message from the public frequency interval, and then use the synchronization channel detection method of the wireless interface technology on the dedicated frequency interval to obtain the synchronization channel information of the wireless interface technology on the dedicated frequency interval. Therefore, the UE can also first successfully obtain synchronization through the synchronization channel on the public frequency interval and read the system broadcast message, and then maintain system synchronization through the synchronization channel or reference signal on the wireless interface technology corresponding to the dedicated frequency area.

[0326] 602. The UE obtains the frequency band information of the two frequency intervals of the cell, the correspondence between the frequency intervals and the wireless interface technology, the characteristic information of the wireless interface technology, and the random access resource information of the cell through the system message sent by the base station on the common frequency interval. The random access resource information is used to instruct the UE to access the cell or instruct the UE to perform uplink synchronization with the cell.

[0327] The base station divides the frequency band of the entire cell into two frequency intervals, and stipulates that each frequency interval uses a different wireless interface technology. One of the wireless interface technologies is the existing LTE technology, corresponding to the public frequency interval, and is used for the transmission of public channels and the user plane of mobile broadband unicast services; the other wireless interface technology uses an interface technology different from the existing technology LTE, corresponding to a dedicated frequency interval, and is used to transmit ultra-low latency M2M service bearers. The base station establishes a corresponding relationship between each of the frequency intervals and the wireless interface technology based on the results of network planning. In this embodiment, the base station sends the frequency band information of the two divided frequency bands to the UE through a system broadcast message in the public frequency interval, and sends the corresponding relationship between the public frequency interval and the existing LTE technology, and the corresponding relationship between the dedicated frequency interval and the wireless interface technology different from the existing LTE technology to the UE.

[0328] This embodiment 7 provides an example of the content of a system message broadcast in a common frequency interval. The base station informs the UE of the correspondence between each frequency interval and the wireless interface technology through a broadcast message in the common frequency interval, as well as the characteristic information of the wireless interface technology supported by the dedicated frequency interval, including: the type of wireless interface technology, including the combination characteristics of multiple access mode, frame structure, CP length, physical channel, etc.; uplink and downlink subframe configuration; and physical channel resource configuration information specific to the wireless interface. The system information in the common frequency interval includes:

[0329] The master system information block (MIB) of the public frequency area includes: the SFN of the public frequency interval; the same SFN used in the dedicated frequency interval, or an integer multiple relationship with the SFN of the public frequency interval; and the bandwidth of the public frequency interval.

[0330] The newly added information elements of the system information block 1 (SIB1) of the public frequency zone include: the identifier of the wireless interface technology supported by the public frequency interval; the downlink bandwidth, sub-band starting offset frequency or center frequency of the dedicated frequency interval, the identifier of the wireless interface technology supported by the dedicated frequency interval, the type of wireless interface technology, including combined characteristics such as multiple access mode, frame structure, CP length, physical channel, etc.; for the TDD system, it also includes the uplink and downlink subframe configurations of the dedicated frequency interval.

[0331] The system information block 2 (SIB2) of the common frequency area includes but is not limited to: PRACH resource configuration of the radio interface technology supported by the common frequency interval; for frequency division multiplexing (FDD) systems, uplink bandwidth; physical layer resource configuration information specific to the radio interface, such as SCMA-related configuration information. For FDD systems, the uplink bandwidth used by each radio interface technology contained in the system information block 2 may be different from the downlink bandwidth.

[0332] After the base station notifies the UE of the correspondence between each frequency interval and the wireless interface technology or the characteristic information of the wireless interface technology, the UE can select the corresponding frequency interval to complete the wireless network access process according to the type of the initiated service.

[0333] After the UE obtains the correspondence between each frequency interval and the wireless interface technology and the characteristic information of the wireless interface technology supported by the dedicated frequency interval from the system broadcast message on the public frequency interval sent by the base station, it can select the corresponding frequency interval to complete the wireless network access process according to the type of the initiated service. In this embodiment, the UE always selects the public frequency interval to perform the wireless network access process.

[0334] When the system information changes, the base station notifies the UE of the system information change by sending a paging message on the common frequency interval. The UE periodically tunes to the common frequency interval to read the system information according to the period configuration of the system message, or only tunes to the common frequency interval to read the paging message at the paging opportunity, and after receiving the notification of the system information change, reads the updated system message in the period when the system information takes effect.

[0335] In the seventh embodiment, the base station broadcasts RACH information in the system information of the public frequency interval, and the random access resource may be located in the public frequency interval or in the dedicated frequency interval.

[0336] The RACH resources on each frequency interval are configured according to the characteristics of the wireless interface technology supported by each frequency interval. Specifically, the format of the RACH channel, the random access preamble configuration, etc. are configured according to the characteristics of the wireless interface technology on each frequency interval. For example, in this embodiment, the RACH resources on the dedicated frequency interval are configured according to the frame structure used by the wireless interface technology of ultra-low latency M2M.

[0337] 603. The UE accesses a wireless network or performs uplink synchronization on the cell random access resources sent by the base station.

[0338] The UE selects a random access channel according to cell RACH resource configuration information, where the cell RACH resource configuration information is obtained from a system message in a common frequency interval read by the UE.

[0339] The UE obtains RACH resource configuration information through the system information of the public frequency interval, including the time-frequency domain resources of the RACH channel and the RACH public resource configuration information. The RACH resource configuration can be located in the public frequency interval and / or the dedicated frequency interval. The UE performs the random access process according to the random access resource selected by itself.

[0340] As described above, the system RACH resources may be located in the public frequency interval or in the dedicated frequency interval, so the UE may select the RACH channel in the public frequency interval for the initial random access process or the RACH channel in the dedicated frequency interval for the initial random access process. If the UE is accessing the network for the first time, the UE uses the selected random access channel to access the network; if the UE is not accessing the network for the first time, the UE can use the selected random access channel for uplink synchronization.

[0341] 604. The UE receives indication information sent by the base station, where the indication information is used to indicate a frequency interval required to be mapped to a data radio bearer DRB of the UE.

[0342] In this embodiment, the base station can send an RRC connection reconfiguration message to the UE as in the fourth and fifth embodiments to configure the frequency interval required for DRB mapping, so that the UE maps the DRB of the ultra-low latency M2M service to the frequency interval corresponding to the ultra-low latency M2M, and maps the DRB of the mobile broadband unicast service to the frequency interval of the LTE technology.

[0343] If the UE accesses the network for the first time, the base station will establish an SRB for the UE before establishing a DRB for the UE. The UE will map the UE's signaling radio bearer SRB to the frequency interval specified by the base station according to the instructions of the base station, and use the wireless interface technology supported by the frequency interval to transmit wireless resource control RRC signaling with the base station.

[0344] 605. The UE maps the DRB of the UE to the frequency interval to which the DRB needs to be mapped.

[0345] 606. The UE transmits the service carried by the service-bearing DRB to the base station using the wireless interface technology supported by the frequency interval mapped by the DRB.

[0346] The UE uses the frequency interval mapped to each DRB determined in step 604 and the wireless interface technology supported by the frequency interval to transmit the service carried by the DRB with the base station.

[0347] Embodiment 8

[0348] This embodiment eight provides another specific implementation method for implementing an access method using wireless interface technology on the terminal side, so as to cooperate with the method using wireless interface technology on the base station side proposed by the present invention.

[0349] Figure 7-a This is a schematic diagram of another terminal accessing a wireless network. The common channels, SRBs, and DRBs belonging to each wireless interface technology are mapped to the dedicated frequency intervals corresponding to each wireless interface technology. When the UE initiates a service, it accesses the wireless network through the dedicated frequency interval corresponding to the service. When the UE initiates service A, it accesses the wireless network through dedicated frequency interval 1. When the UE initiates service B, it accesses the wireless network using dedicated frequency interval 2.

[0350] When the system does network planning, the frequency band of the entire cell is divided into multiple frequency intervals, and each frequency interval is specified to use a different wireless interface technology. Optionally, the frequency range of the entire cell is divided into two dedicated frequency intervals, using two different wireless interface technologies.

[0351] In this embodiment eight, the LTE wireless interface technology carries the SRB and DRB used for transmitting mobile broadband unicast services, and uses the wireless resources, MAC entities and physical layer (PHY) entities used by the LTE technology; the wireless interface technology with a frame structure different from that of the LTE technology carries the SRB and DRB used for ultra-low latency M2M services, and uses the wireless resources, MAC entities and physical layer (PHY) entities used by the wireless interface technology with a frame structure different from that of the LTE technology.

[0352] In the eighth embodiment, the UE detects common channels such as a synchronization channel (SCH) and a system broadcast message from one of the dedicated frequency intervals of the two cell frequency intervals, and accesses the system according to the RACH resources indicated by the system broadcast message sent on the dedicated frequency interval. The RACH resources are located in the dedicated frequency interval. The UE can select one of the RACH resources to access the wireless network, or access the wireless network according to the random access resources indicated by the base station.

[0353] like Figure 7-b The implementation method provided in this embodiment may include:

[0354] 701. User equipment UE detects a synchronization channel in a dedicated frequency interval to obtain and maintain system synchronization.

[0355] The UE detects a synchronization channel at a center frequency point of the dedicated frequency interval according to the center frequency points of the two stored dedicated frequency intervals.

[0356] Optionally, the UE obtains synchronization channel information using a synchronization channel detection method in the prior art LTE, or obtains synchronization channel information using a synchronization channel detection method in a wireless interface technology with a frame structure different from that of the prior art LTE technology, and achieves downlink synchronization with the base station.

[0357] 702. The UE receives a system message sent by the base station in a dedicated frequency interval, obtains frequency band information of the dedicated frequency interval, a correspondence between the dedicated frequency and a wireless interface technology, characteristic information of the wireless interface technology, and random access channel RACH resource information of the cell.

[0358] The base station divides the frequency band of the entire cell into two frequency intervals, each of which uses a wireless interface technology. One of the wireless interface technologies is the existing LTE technology, corresponding to the public frequency interval, and is used for the transmission of public channels, signaling wireless bearers, and the user plane of mobile broadband unicast services; the other wireless interface technology uses an interface technology different from the existing LTE technology, corresponding to a dedicated frequency interval, and is used to transmit ultra-low latency M2M service bearers.

[0359] Optionally, the base station sends the frequency band information of the two divided frequency bands to the UE through the system broadcast message of the dedicated frequency interval corresponding to the two frequency intervals, and sends the correspondence between the dedicated frequency interval and the wireless interface technology different from the existing LTE frame structure to the UE.

[0360] For example, the base station informs the UE of the correspondence between the dedicated frequency interval and the wireless interface technology, as well as the characteristic information of the wireless interface technology through a broadcast message of the dedicated frequency interval. The characteristics of the wireless interface technology include: wireless interface technology type, including multiple access mode, frame structure, CP length, physical channel and other combination characteristics; uplink and downlink subframe configuration; wireless interface specific physical channel resource configuration information.

[0361] After the UE obtains the correspondence between the dedicated frequency interval and the wireless interface technology or the characteristic information of the wireless interface technology from the system broadcast message on the dedicated frequency interval sent by the base station, it can select the corresponding frequency interval to complete the wireless network access process according to the type of service initiated. The relationship between the type of service initiated and the selected frequency interval is information known to the UE.

[0362] The UE obtains RACH configuration information from the system information of the two frequency intervals respectively, and the cell RACH resource configuration information is obtained from the system message of the dedicated frequency interval read by the UE.

[0363] It is understandable to those skilled in the art that the RACH channel format and random access preamble on the frequency interval corresponding to the wireless interface technology are configured according to the characteristics of different wireless interface technologies. For example, the RACH resources on the frequency interval corresponding to the ultra-low latency M2M service are configured according to the frame structure used by the wireless interface technology of the ultra-low latency M2M.

[0364] In the eighth embodiment, the base station broadcasts RACH information in the system information of the dedicated frequency interval, and the RACH resources are located in the dedicated frequency interval. The UE obtains the RACH resource configuration information on the dedicated frequency interval from the system information of the two dedicated frequency intervals, including the time-frequency domain resources of the RACH channel and the RACH common resource configuration information.

[0365] 703. The UE accesses a wireless network or performs uplink synchronization on the cell random access resources sent by the base station.

[0366] The UE selects a dedicated frequency interval for random access according to the initiated service type, selects a RACH channel from the RACH resource configuration obtained in the system broadcast message in the dedicated frequency interval, and performs a random access process. If the UE is accessing the network for the first time, the UE uses the selected random access channel to access the network; if the UE is not accessing the network for the first time, the UE can use the selected random access channel for uplink synchronization.

[0367] For example, if the UE initiates a mobile broadband unicast service, the frequency interval selected by the UE for random access is a dedicated frequency interval corresponding to the LTE technology, and the UE selects a RACH channel from the RACH resources in the frequency interval corresponding to the LTE wireless interface technology for random access; if the UE initiates an ultra-low latency M2M service, the frequency interval selected by the UE for random access is a dedicated frequency interval corresponding to an interface technology different from the existing LTE technology, and the UE selects a RACH channel from the RACH resources in the frequency interval corresponding to the interface technology different from the existing LTE technology for random access.

[0368] 704. The UE receives indication information sent by the base station, where the indication information is used to indicate the frequency interval required to be mapped to the data radio bearer DRB of the UE.

[0369] The base station can send an RRC connection reconfiguration (RRCConnectionReconfiguration) message to the UE as in Embodiments 4 and 5 to configure the frequency interval to which the data DRB is required to be mapped. The MAC layer and the physical layer of the wireless interface technology supported by the established DRB and the frequency interval are mapped. For example, if the DRB is mapped to the existing LTE technology, the DRB is mapped to the MAC layer and the physical layer of the LTE technology.

[0370] It is worth noting that if the UE accesses the network for the first time, the base station needs to establish an SRB for the UE before establishing a DRB for the UE, and the base station establishes a mapping relationship between the SRB of the UE and the frequency interval.

[0371] In specific implementation, the base station may map the SRB of the UE to the dedicated frequency interval selected by the UE for random access. For example, if the UE performs random access on the dedicated frequency interval corresponding to the existing LTE technology, the base station maps the SRB of the UE to the frequency interval corresponding to the existing LTE technology; if the UE performs random access on the dedicated frequency interval corresponding to the wireless interface technology different from the existing LTE technology, the base station maps the SRB of the UE to the frequency interval corresponding to the wireless interface technology different from the existing LTE technology.

[0372] The UE maps the signaling radio bearer SRB of the UE to a designated frequency interval according to the instruction of the base station, and transmits radio resource control RRC signaling with the base station using the radio interface technology supported by the frequency interval.

[0373] 705. The UE maps the DRB of the UE to the frequency interval to which the DRB needs to be mapped.

[0374] 706. The UE uses the wireless interface technology supported by the frequency interval mapped by the DRB to transmit the service carried by the service bearer DRB with the base station.

[0375] The UE uses the frequency interval mapped to each DRB determined in step 703 and the wireless interface technology supported by the frequency interval to transmit the service carried by the DRB with the base station.

[0376] Embodiment 9

[0377] Embodiment 9 of the present invention discloses a method using a wireless interface technology. In this embodiment, the SOR controller determines the frequency interval used by the service so that the base station maps the DRB carrying the service to the required frequency interval.

[0378] The frequency range used by the service is configured by the SOR controller, which is an independent network element device or a logical functional unit located in the network element device. If the SOR controller is a logical functional unit, it is preferably located in the base station, and optionally in the mobility management equipment (MME).

[0379] In order to better understand the specific location of the SOR controller in the network, take the LTE system as an example to explain the connection relationship between the SOR controller and other network elements in the LTE system. Figure 8-a As shown, the SOR controller is connected to the base station (including macro base station and small base station) through the Sx interface, and the SOR controller is connected to the MME through the Sy interface. The Sx interface and the Sy interface are optional. If the SOR controller is located inside the base station, the Sx interface is optional; if the SOR controller is located inside the MME, the Sy interface is an optional interface. In the figure, except for the Sx interface and the Sy interface, the interfaces between other network elements are all existing interfaces in the LTE system.

[0380] The SOR controller configures the service and the corresponding frequency interval semi-statically. For example, within a certain time range, the SOR controller keeps the configuration of the service and the corresponding frequency interval unchanged. The SOR controller periodically changes the mapping relationship between the service and the corresponding frequency interval according to changes in service demand, interference, load, etc.

[0381] Optionally, the SOR controller may configure the corresponding frequency interval of the service dynamically. For example, when a UE with a specific service initiates a service request, a wireless interface technology and a frequency interval are allocated to the service.

[0382] The method for the SOR controller to determine the frequency interval used by services in the system disclosed in the ninth embodiment of the present invention is as follows: Figure 8-b As shown, the following steps are included:

[0383] 801. The SOR controller obtains cell resource information, service information and service requirements from a network element or a logic unit.

[0384] The cell resource information includes the frequency intervals into which the base station divides the frequency band of the cell, the wireless interface technology supported by the frequency intervals, the characteristic information of the wireless interface technology, etc. The different types of services include services with different service qualities (QoS) or services with different technical characteristics. The services with different technical characteristics include MBMS services, unicast services, M2M services, etc.

[0385] The network element or logic unit includes a base station, a core network element or a service server. For example, the SOR controller obtains cell resource information from the base station, or may also obtain the service demand and service information; the SOR controller obtains the service information and service demand from the MME or the service server.

[0386] The SOR controller may request the network element or the logical unit to download the service requirements and service information of the unicast service, or the network element or the logical unit may actively send the service requirements and service information of the unicast service to the SOR controller;

[0387] 802. The SOR controller determines a frequency range required for a service according to the cell resource information, the service information and the service demand.

[0388] The SOR controller determines the frequency interval used by the service according to the cell resource information, the service information and the service demand obtained from the system network element or logic unit in the above steps.

[0389] 803. The SOR controller informs the network element or logical unit of the frequency interval used for transmitting the service.

[0390] After the SOR controller informs the network element or logic unit of the frequency interval required for transmitting the service, the network element or logic unit can schedule the service according to the frequency interval used by the service. For example, the base station schedules the service of the UE according to the frequency interval used determined by the SOR controller for the service of the UE, and maps the DRB carrying the service of the UE to the required mapped frequency interval.

[0391] If the SOR controller is a logical functional entity located in the base station, then determining the frequency interval required for transmitting the service belongs to the function of the base station. Optionally, the base station negotiates with other base stations through the X2 interface to determine the frequency interval used by the service.

[0392] For those skilled in the art, it is understandable that the frequency range used by the UE's service can be changed. For example, if the UE moves from a source cell to a target cell, and the target cell does not support the wireless interface technology used by the UE, or the wireless interface technology originally used by the UE cannot be provided in the target cell due to interference or load reasons, the target cell configures a new wireless interface technology and a corresponding frequency range for the UE's service.

[0393] Embodiment 10

[0394] Embodiment 10 of the present invention discloses a method for using a wireless interface technology. In this embodiment, a SOR controller determines a frequency interval used by a wireless interface technology of a cell, so that a base station can divide or re-divide the frequency interval of the cell.

[0395] The SOR controller is used to ensure that the wireless interface technology in the adjacent co-frequency cell set or cell group uses the same frequency interval, thereby avoiding interference problems. If different wireless interface technologies are used in the same frequency interval between adjacent cells, the resources used by the reference signals, control channels or service channels of the different wireless interface technologies supported by the same frequency interval are not orthogonal, which will cause the signals between adjacent cells in the same frequency interval to interfere with each other; but if the same wireless interface technology is used in the same frequency interval between adjacent cells, because the resources used by the reference signals, control channels or service channels of the same wireless interface technology are orthogonal, and the existing wireless interface technology has a means of eliminating co-frequency interference, it will greatly reduce the interference between adjacent cells. Therefore, the SOR controller can coordinate the configuration of the frequency intervals corresponding to the wireless interface technologies of multiple cells to ensure that the co-frequency interference between adjacent cells is low.

[0396] Existing methods for eliminating co-channel interference, for example, the soft frequency reuse (SFR) technology or the fractional frequency reuse strategy in the LTE system can solve the co-channel interference between adjacent cells; for another example, the collaborative beamforming technology in the LTE system, or the use of reference signal muting and other methods can solve the co-channel interference between adjacent cells;

[0397] In addition, the SOR controller can also keep the downlink / uplink subframes in the TDD radio interface technology configured according to a consistent rule within the cell group, avoiding mutual interference between uplink and downlink signals of the same radio interface technology in adjacent cells.

[0398] The SOR controller is an independent network element, or a logical functional entity in the network element. If the SOR controller is a logical functional entity located in the base station, then the function of the SOR controller to determine the frequency range used by the wireless interface technology is part of the base station function. Optionally, the base station can negotiate with other base stations through the X2 interface to determine the frequency range used by the wireless interface technology.

[0399] Embodiment 11

[0400] This embodiment eleven provides a specific example of the method of the present invention using multiple wireless interface technologies.

[0401] In this embodiment, when the system makes network planning, the frequency band of the entire cell is divided into two frequency intervals, and it is stipulated that each frequency interval uses a different wireless interface technology. Among them, the wireless interface technology used in one frequency interval is the existing LTE technology, which is used for the transmission of mobile broadband unicast services; the other frequency interval uses an interface technology with a different CP length from the existing unicast mobile broadband LTE technology, which is used to transmit MBMS services. In this embodiment, the wireless interface technology supported by a frequency interval in the cell is the LTE wireless interface technology, the LTE wireless interface technology carries the DRB of the mobile broadband unicast service, and the mobile broadband unicast service uses the wireless resources, MAC entity and physical layer (PHY) entity used by the LTE technology; the other frequency interval corresponds to the use of a wireless interface technology with a different CP length of OFDM symbols from the LTE technology, the wireless interface technology carries the MBMS service, and the DRB of the MBMS service uses the wireless resources, MAC entity and physical layer (PHY) entity used by the wireless interface technology with a frame structure different from that of the LTE technology.

[0402] The schematic diagram of resource configuration method of this embodiment 11 can be found in Figure 9-a .

[0403] like Figure 9-aAs shown, the full frequency f of the cell is divided into two frequency intervals, wherein f1 is a public frequency interval for unicast service data transmission; and f2 is a dedicated frequency interval for MBMS service data transmission. Optionally, f1 and f2 are still configured in a frequency division manner, f1 is still used for unicast service, and f2 is still used for MBMS service. At the same time, unicast service and MBMS service are configured in a time division manner in the f1 frequency interval, for example, as in the prior art, some Multimedia broadcast multicast single frequency network (MBMSFN) subframes are configured in the LTE system frame.

[0404] The bandwidths occupied by f1 and f2 may be dynamically adjusted by the SOR controller according to changes in business requirements.

[0405] The eleventh embodiment discloses a process of configuring cell resources in a frequency division manner based on services.

[0406] In order to better understand the embodiment of the present invention, the process of configuring cell resources disclosed in the embodiment of the present invention is described below.

[0407] The main process of the process is that the SOR controller negotiates with the multi-cell / multicast coordination control entity (MCE) the bandwidth and frequency interval information required for the MBMS service, and the SOR controller determines the frequency domain resources configured for the unicast service and the MBSM service according to the wireless resource allocation strategy. The SOR controller notifies the base station of the frequency domain resource allocation results of the unicast service and the MBMS service configuration, and the resource allocation results are the bandwidth and frequency interval of the unicast service and the MBSM service. After the base station determines the frequency domain resource allocation results of the unicast service and the MBMS service configuration, it starts to configure the resources of the unicast service and the MBMS service of the UE. After the MCE negotiates the MBSM service frequency interval with the SOR controller, it schedules the MBMS service according to the frequency resources occupied by the MBMS service.

[0408] Optionally, the SOR controller is a logical unit entity located inside the base station, and the base station negotiates the unicast service and the MBMS service bandwidth and frequency interval with other base stations in other MBMS synchronization areas or MBMS service areas, and with the MCE. After the base station negotiates the unicast service and the MBMS service bandwidth and frequency interval, it starts to configure the UE's unicast service and MBMS service resources. After the MCE negotiates the MBMS service frequency interval, it schedules the MBMS service according to the frequency resources occupied by the MBMS service.

[0409] In order to better understand the process of configuring cell resources in a frequency division manner in this embodiment, the message flow of configuring cell resources in a frequency division manner disclosed above may include the following steps: Figure 9-b shown.

[0410] 901. The SOR controller obtains service requirements and service information of a unicast service from a base station.

[0411] The SOR controller may request the base station to download the service requirements and service information of the unicast service, or the base station may actively send the service requirements and service information of the unicast service to the SOR controller.

[0412] 902. The SOR controller obtains service requirements and service information of the MBMS service from the base station.

[0413] 903. The SOR controller negotiates with the MCE to determine the frequency ranges used by the unicast service and the MBMS service.

[0414] 904. The SOR controller starts a wireless resource allocation strategy to determine the frequency intervals used by the unicast service and the MBMS service.

[0415] 905. The SOR controller notifies the base station of the frequency range used by the unicast service and the MBMS service.

[0416] 906. When the SOR controller independently determines the bandwidth and frequency interval used by the unicast service and the MBMS service, the SOR controller notifies the MCE of the frequency interval used by the MBMS service.

[0417] 907. The base station schedules the unicast service and the MBMS service according to the frequency interval used by the unicast service and the MBMS service notified by the SOR controller.

[0418] 908. The MCE schedules the MBMS service according to the frequency interval occupied by the MBMS service notified by the SOR controller.

[0419] On the other hand, the eleventh embodiment of the present invention further discloses a method for configuring the frequency points and common channels of a system, and a method for configuring system information when a UE accesses a wireless network in a centralized manner.

[0420] A method for configuring system frequencies and common channels disclosed in this embodiment is as follows.

[0421] There are three ways to set the cell center frequency and public channel.

[0422] Method 1:

[0423] The system sets up center frequency points in f1 and f2 respectively. The center frequency point of f1 is set at the center frequency of f1, and the center frequency point of f2 is set at the center frequency of f2.

[0424] The system sets common channels in the frequency interval corresponding to f1, including synchronization channel (PSS / SSS), cell reference signal (CRS), broadcast channel (BCH), paging channel (PCH) and random access channel.

[0425] The system does not set up common channels in the f2 part, including synchronization channel and broadcast channel (PSS / SSS / BCH), cell reference signal (CRS), paging channel (PCH) and random access channel.

[0426] The physical layer processes of the UE, such as synchronization process, measurement process, system information reading process, random access process and paging process, are all performed on the f1 frequency interval. Before the UE accesses the system, it can only tune the receiver to the f1 frequency band for access, because only the f1 frequency band supports cell discovery and network access.

[0427] In the first method, the UE accesses the wireless network in the public frequency interval, that is, accesses the wireless network on f1.

[0428] Method 2:

[0429] The system only establishes one central frequency point, which is established at the central frequency of the total carrier frequency band f of the cell.

[0430] The system sets up common channels of the system within the frequency bandwidth of f, including synchronization channel (PSS / SSS), cell reference signal (CRS, cell reference signal), broadcast channel (BCH), paging channel (PCH) and random access channel.

[0431] The physical layer processes such as synchronization process, measurement process, system information reading process, random access process and paging process of the UE are all performed on the entire cell bandwidth of f. Before accessing the system, the UE needs to tune the receiver to the full frequency band f for access. The system supports cell discovery and network access on the full frequency band f.

[0432] In mode 2, the UE accesses the wireless network on the total frequency band of the cell, that is, accesses the wireless network on f.

[0433] Method 3:

[0434] The system sets up center frequency points in f1 and f2 respectively. The center frequency point of f1 is set at the center frequency of f1, and the center frequency point of f2 is set at the center frequency of f2.

[0435] The system sets a common channel in the frequency interval corresponding to the f1, including one or more of a synchronization channel (PSS / SSS), a cell reference signal (CRS), a broadcast channel (BCH), a paging channel (PCH) and a random access resource. The common channel on the f1 frequency interval is a common channel for unicast services. For example, the random access resource on the f1 frequency interval is for access to the unicast service. For another example, the BCH on the f1 frequency interval is for the wireless interface technology of the unicast service.

[0436] At the same time, the system also sets up common channels in the f2 part, including one or more of synchronization channels and broadcast channels (PSS / SSS / BCH), cell reference signal (CRS), paging channel (PCH) and random access channel. The common channels on the f2 frequency interval are common channels for MBSM. For example, the random access resources on the f2 frequency interval are for access to the MBSM service. For another example, the BCH on the f2 frequency interval is for the wireless interface technology of the MBSM service.

[0437] Physical layer processes such as synchronization process, measurement process, system information reading process, random access process and paging process of the UE can be performed in the f1 frequency interval or the f1 frequency interval. Before the UE accesses the system, it first tunes the receiver to the f1 frequency band to access the wireless network, or before the UE accesses the system, it first tunes the receiver to the f2 frequency band to access the wireless network. Both the f1 frequency band and the f2 frequency band support cell discovery and access.

[0438] In mode 3, the UE accesses the wireless network in a dedicated frequency interval, that is, accesses the wireless network on f1 or f2.

[0439] The eleventh embodiment of the present invention further discloses a system information configuration method, which is described in detail as follows: According to the system information configuration method, the UE can access the wireless network from the public frequency interval.

[0440] The master information block MIB in the system information broadcasts the actual downlink bandwidth of the cell, and the downlink bandwidth of the cell is the bandwidth of f1 or the bandwidth of the total frequency band f of the cell. The specific broadcast of f1 or f is determined according to the configuration method of the center frequency. If the system configures the system frequency and common channels according to the above method 1, the MIB broadcasts the frequency band bandwidth of f1; if the system configures the system frequency and common channels according to the above method 2, the MIB broadcasts the frequency band bandwidth of f.

[0441] The MBSM system frame subframe configuration (MBSFN-SubframeConfig) of the f2 frequency band is added to the system information block 2 (SIB2), and the MBSFN-SubframeConfig can be any frame in the system; optionally, because the MBMS service subframe can also be configured on the frequency band f1, the MBMSFN subframe on the f1 frequency band can also be configured in the SIB2. Specifically, the MBMSFN subframe configuration on the f1 frequency band and the f2 frequency band shall be indicated in the SIB2; optionally, the MBMSFN subframe on the f2 frequency band is not configured in the SIB2, and the UE can use all subframes on the f2 frequency band as the MBMSFN subframe.

[0442] The f2 frequency band bandwidth information is added in the SIB2. Optionally, if the f2 frequency band bandwidth is not added in the system information block SIB2, the f2 frequency band bandwidth may also be added in the system information block SIB1.

[0443] The MBSFN area information list (mbsfn-AreaInfoList-r9) information element in the system information block 31 (SIB13) is modified as follows:

[0444] The information element mcch-Config-r9 in mbsfn-AreaInfoList-r9 indicates that the MBMS control channel (MCCH) in the radio interface technology on the f2 frequency band can use any subframe of the interface technology on the f2 frequency band.

[0445] Optionally, if the system also configures the MBSFN subframe on the f1 frequency band, the SIB13 also needs to configure MCCH for the radio interface technology on the f1 frequency band.

[0446] The MBSM service resource allocation method of the f1 frequency band and the f2 frequency band of all cells in the same MBSFN area is the same. Specifically, the MBMSFN subframe of the wireless interface technology of the f2 frequency band, the MBMSFN subframe of the wireless interface technology of the f1 frequency band, the MCCH configuration of the wireless interface technology of the f2 frequency band, and the MCCH configuration of the interface technology of the f1 frequency band are the same.

[0447] It is understandable to those skilled in the art that, since there is no common channel in the f2 frequency band, f2 does not support cell discovery and network access, and the UE can only access the wireless network through the system information on the f1 frequency band, or access the wireless network through the system information on the entire frequency band f. Therefore, the wireless interface technology of the f2 frequency band does not need to reserve the two OFDM symbols required for the PDCCH channel, and all symbols of each subframe on the f2 frequency band are used for eMBMS; optionally, for the sake of backward compatibility of the system, the wireless interface technology of the f2 frequency band can also reserve the two OFDM symbols required for the PDCCH channel.

[0448] It can be seen by those skilled in the art that, since there is no common channel on f2, the UE's serving cell / neighboring cell radio resource management (RRM) measurement can only be based on the measurement of the CRS quality of the f1 frequency band, or based on the measurement of the CRS quality of the entire cell frequency band f. The UE's serving cell channel state information (CSI) measurement can also only be based on the measurement of the channel state information reference signal CSI-RS of the f1 frequency band, or based on the measurement of the channel state information reference signal CSI-RS of the entire cell frequency band f.

[0449] It is understandable that if the system configures the MBMS FN subframe on the f1 frequency band, the MBMS counting response message can be sent through the MBMS uplink channel of the f1 frequency band, otherwise the MBMS counting response message is sent through the MBMS uplink channel of the f2 frequency band.

[0450] The steps after the base station completes the system sending the broadcast message, including the implementation process of mapping the UE's DRB to the specified frequency interval, and the operation process of the base station side using the wireless interface technology supported by the frequency interval mapped by the DRB to transmit the service carried by the service-bearing DRB to the base station, are consistent with Example 4 and will not be repeated here.

[0451] The subsequent operation steps of the UE are consistent with those of Example 7 and will not be repeated here.
