Description

FIELD OF THE INVENTION

[0001] The present invention relates to the field of communication technology, and, in particular, to a method for exchanging information, a base station, and a user device.

BACKGROUND

[0002] With the rapid development of communication technologies, wireless communication technologies are widely used, due to their advantages of convenience, efficiency in information transfer and reduced costs. However, as the demand for spectral resources in wireless communication systems is continuously increasing, the spectral resources for wireless communication systems are gradually decreasing. Being a non-renewable type resource, a spectral resource cannot be occupied simultaneously by another communication system, as long as it is already occupied by the communication system. To improve system bandwidth and resolve the conflict between spectral resources in communication systems and the growing demands of wireless communications, improved long-term development (improved long-term development, LTE-A) on a 3rd generation partnership project (3rd generation partnership project, 3GPP), provides spectral aggregation technology, that is, carrier aggregation (carrier aggregation, CA).

[0003] By utilizing carrier aggregation technology, multiple adjacent, or non-adjacent, component carriers (component carrier, CC) can be aggregated to obtain greater bandwidth, thereby increasing peak data rate and system throughput. In a communication system, after carrier aggregation is formed, a user device (user device, UE) can establish a network exchange of information by using multiple serving cells (serving cell) in the administration area of one or more base stations (base station, BS) . The frequencies of the component carriers that correspond to different serving cells are usually different.

[0004] To date, in the process of forming carrier aggregation, component carriers may be provided by the same base station, or may be provided by different base stations; the former is referred to as carrier aggregation within the base stations (Intra-BS CA), and the latter is referred to as carrier aggregation among the base stations (Inter-BS CA).

[0005] With regard to aggregation of carriers within the base stations, in the LTE-A system, multiple, co-located, component carriers are provided by the base station, or multiple, incompatible, component carriers are provided separately by the base station and the remote radio head (remote radio head, RRH) of the base station. The base station generates, in accordance with specific wireless conditions (such as channel quality and control signal strength) and service conditions, carrier aggregation for a user equipment UE, which is located in the common coverage area of the aforementioned multiple component carriers.

[0006] With regard to carrier aggregation among base stations, the UE may establish relationships of radio communications with one or more base stations that are involved in the formation of carrier aggregation, that is, establish network communication with multiple serving cells within the administration area of one, or several base stations. In the process of forming carrier aggregation among base stations, one base station (which is referred to as the first base station, hereinafter) is usually responsible for splitting / flattening the data. The first base station transmits a portion of downstream data, such as a unit of protocol data (unit of protocol data, PDU) over a packet data protocol PDCP (packet data protocol, PDCP) and radio link control PDUs (radio link control, RLC), to one, or several other base stations (which are referred to as second base stations, hereinafter). As you can see, when aggregating carriers among base stations, the UE can receive downstream data using the radio links of multiple base stations, and transmit uplink data using the radio links of multiple base stations, and all uplink data of the UE received at least one of the aforementioned second base stations are transmitted to the first base station, which is responsible for splitting / data reduction. Turning to FIG. 1, FIG. 1 is a schematic drawing of carrier aggregation among base stations in an LTE system. The first base station eNBl and the second base station eNB2, individually, schedule the UEs in an independent manner.

[0007] In a wireless communication system, after the UE establishes a radio resource management (radio resource management, RRC) connection with a base station, the base station schedules the UE. When aggregating carriers among base stations, multiple base stations that participate in carrier aggregation individually plan the UEs in an independent manner. In a situation in which a transit link (transit) does not satisfy the required conditions, referring to FIG. 1, the first base station eNBl transmits the first transport block TB2 to the UE, the second base station eNB2 transmits the second transport block TB2 to the UE, and the total number of bits corresponding to the first transport block TB1 and the second transport block TB2 exceeds the transmit power of the UE, which leads to that the UE is not able to receive one of the transport blocks or is not able to receive both transport blocks.

[0008] As you can see, during aggregation of carriers among base stations, as soon as multiple base stations transmit an excessively large amount of data to the UE, the UE user device is forced to discard some, or all, of the data that it should receive, which leads to an error receiving data.

[0069] From Table 1, it can be understood that the UE category (UE category) defines a combination of downlink power and uplink power corresponding to each UE category. The parameter "maximum number of bits of transport blocks of the downstream shared channel (downstream, shared, channel, DL-SCH) received within the transmission time interval (transmission time interval, TTI) (maximum number of bits of transport blocks DL-SCH received within TTI) ”, determines the maximum number of bits of the DL-SCH transport blocks that can be received by the UE, within the TTI in the DL-SCH, and represents the peak data rate supported by the UE category; the parameter "maximum number of bits of a DL-SCH transport block received within a TTI (maximum number of bits of a DL-SCH transport block received within a TTI)" determines the maximum number of bits of DL-SCH transport blocks that can be received by a UE in a transport block , within the TTI in DL-SCH; the parameter "total number of soft channel bits (total number of soft channel bits)" determines the number of channel bits available (available) for processing in a hybrid automatic repeat request (hybrid automatic relay request, HARQ); the parameter "maximum number of supported levels for spatial multiplexing in the downstream channel (maximum number of supported levels for spatial multiplexing in DL)" determines the maximum number of supported levels for the action of spatial multiplexing in the downlink antenna of multiple output - multiple input (multiple output - multiple input, MIMO) . In an LTE system, the TTI duration is the duration (1 ms) of a subframe (subframe).

[0070] In relevant standards, the maximum number of downlink PDCP service data units (SDUs) within the TTI are described as shown in FIG. 2.

[0071] All parameters in table 1, and in table 2, are parameters that represent the radio access power of the UE.

[0072] In this embodiment of the present invention, the process of determining, at the first base station, the first data allocation information, for the first base station, and the second data allocation information, for the second base station, is as follows: receive, at the first base station, the measurement report, which is reported by the user device of the UE, and receive a signal quality parameter of a serving cell of at least one base station, and identification information corresponding to the UE, which are carried in the measurement report niy; and receive, at the first base station, in accordance with the signal quality parameter, and with the identification information corresponding to the UE, the first data allocation information, for the first base station, and the second data allocation information, for the second base station, where the data allocation information includes itself a threshold value of data allocation, and / or information matching the time of data allocation. As can be understood from the aforementioned process, the data allocation information is obtained in accordance with the signal quality parameter, and the signal quality parameter relates to the load, the conditions of the wireless connections, the data of the splitting algorithm, and the traffic control situations that correspond to the serving cells within the administration area of the first the base station, and within the administration area of the second base station; therefore, the first data allocation information and the second data extraction information change with changes in load, wireless conditions, data partitioning algorithms and traffic control situations that correspond to serving cells, within the administration area of the first base station, and within the administration area of the second base station.

[0073] In the above process, the process of obtaining, at the first base station, the first data allocation information and the second data extraction information, in accordance with the signal quality parameter, and with the identification information corresponding to the UE, is as follows: receive, at the first base station, radio access power parameter of the UE, in accordance with the identification information corresponding to the UE; and, in accordance with the signal quality parameter and the radio access power parameter of the UE, the first data allocation information for the first base station is determined, at the first base station, and the second data allocation information, for the second base station, is determined. In this embodiment of the present invention, the first data allocation information for the first base station and the second data allocation information for the second base station are obtained in accordance with the signal quality parameter. In those cases where the signal quality corresponding to the serving cell within the administration area of the base station is the best, a larger amount of data to be transmitted can be allocated to the base station so that the base station with the best signal quality carries a larger amount of data, which should be transmitted, which effectively increases the throughput of the system.

[0074] Optionally, the data allocation information may also include an effective data extraction time. The effective data allocation time is set by the first base station, and the first base station transmits the effective data allocation time to the second base station so that the second base station processes, in accordance with the effective data allocation time, the time at which the second base station transmits data to the UE . The effective data allocation time may take the form of a point in time, such as time marking information (time marking), or may take the form of a frame number of an absolute time information system, such as SFN (frame number).

[0075] In the process of generating carrier aggregation among base stations, the first base station may determine, in accordance with a predetermined period, the first data allocation information for transmitting the first data to the UE, and determine the second data allocation information for transmitting the second data to the UE a second base station that performs carrier aggregation together with the first base station; and the first base station may also receive the first data allocation information and the second data extraction information, determining, in accordance with the measurement report, or with the quality of service (quality of service, QoS) that are reported by the user equipment UE that the second data allocation information should be transmitted to the second base station. Specifically, in cases where the first base station determines, in accordance with the measurement report, or QoS, which are reported by the user equipment of the UE, that the amount of data transmitted by the first base station and the second base station to the user equipment of the UE is greater than the total amount of data that can be received in accordance with the radio access power of the UE, the first base station determines the first data allocation information for transmitting the first data to the UE, and determines the second data allocation information for second data to the UE by the second base station.

[0076] In this embodiment of the present invention, a data allocation threshold included in the data allocation information is obtained in accordance with a radio access power parameter of the UEs corresponding to the UE. Specifically, the data allocation threshold value includes one, or any combination of the following parameters: maximum number of DL-SCH transport block bits received within the TTI, maximum number of DL-SCH transport block bits received within the TTI, total soft channel bits, the maximum number of supported layers for downlink spatial multiplexing, and the maximum number of PDCP SDUs, within the TTI. In cases where the first base station transmits the second data allocation information, which includes the data allocation threshold, to the second base station, the first base station, and the second base station can transmit data, in a predetermined amount, to the user equipment UE , in accordance with the data allocation information. If the UE radio access power parameter is equal to TV, the amount of data transmitted by the first base station to the UE is TB1, the amount of data transmitted by the second base station to the UE is TB2, and TB1 + TB2 <TB, then the total amount of data, within TTI, does not exceed the transmit power of the UE when the first base station and the second base station simultaneously transmit data to the UE, as shown in FIG. 4. Optionally, the sum of the data allocation threshold included in the first data extraction information and the data isolation threshold included in the second data extraction information is equal to the total amount of data that can be received in accordance with the radio access power UE In cases where the data allocation threshold includes multiple radio access power parameters of the UE, information about the amounts of data allocated by the first base station to the first base station and to the second base station must comply with all of the above multiple parameters. In addition, the first base station may also transmit second data allocation information, which includes a relative data allocation indicator, and a radio access power parameter of the UE, to the second base station, and instruct the second base station to receive the data allocation threshold, in accordance with a relative data allocation rate, and with a UE radio access power parameter.

[0077] Furthermore, in this embodiment of the present invention, the data allocation information includes subframe information. The first base station, and the second base station, can transmit data to the UE in accordance with the subframe information, that is, the subframe information includes at least one subframe number allocated by the first base station to the first base station, and at least one subframe number allocated by the first base station to the second base station.

[0078] Optionally, the first base station receives a bitmap attribution map of transmission subframes (a bitmap attribution of subframes) in accordance with at least one number of subframes (which is referred to as the first number of subframes hereinafter) allocated to the first base stations and with at least one subframe number (which is referred to as the second subframe number hereinafter) allocated to the second base station, that is, the bitmap attribution card of the subframes includes numbers for the frames occupied separately when the first base station and the second base station transmit data to the UE; the first base station transmits the bitmap attribution subframes map to the UE at a predetermined point in time, and instructs the UE to switch, in accordance with the bitmap attribution map of the transmission subframes, and in the subframe corresponding to the first subframe number of the first base station, an inactive state discontinuous reception in a serving cell within the administration area of the second base station. In addition, the first base station may also transmit the bitmap attribution card, and the effective data allocation time, to the user equipment of the UE at a predetermined time, and instruct the UE to switch according to the effective data allocation time and the card elementwise attribution of transmission subframes, and in the subframe corresponding to the first number of subframes of the first base station, after a time corresponding to the effective data allocation time, to the inactive the intermittent reception state in the serving cell within the administration area of the second base station, as shown in FIG. 5.

[0079] The pre-set point in time may be a point in time before transmitting the second data allocation information from the first base station to the second base station, or a point in time during the transmission of the second data allocation information, from the first base station to the second base station, or, further, a point in time after transmitting the second data allocation information from the first base station to the second base station; in addition, the first number of subframes and the second number of subframes are different. For example, the first numbers of subframes, which are from 1 to 5, indicate that the first base station transmits data to the UE in subframes, from 1 to 5, of the subframes of a frame, and the second numbers of subframes, which are from 6 to 10, indicate that the second base station transmits data to the UE in subframes, from 6 to 10, in the subframes of a certain frame. Thus, different base stations transmit data to the UE in different subframes. In this case, only one base station transmits data to the UE in each subframe; after the base station receives the radio access power parameter of the UE, the base station can control so that the amount of data transmitted to the UE respects the total amount of data that can be received in accordance with the radio access power of the UE.

[0080] In the above process, an inactive discontinuous reception state means that the UE is not in active time (active time). In the subframe corresponding to the inactive state, the UE does not listen to signals on the physical downlink control channel (physical downlink control channel, PDCCH), does not accept the physical downlink shared channel, (the physical downlink shared channel, PDSCH), does not transmit information such as the periodic sounding reference signal (sounding reference signal, SRS) and the channel quality indicator (channel quality indicator, CQI), and does not transmit uplink physical uplink information used by the joint stno channel (Physical Uplink used together, a channel, PUSCH). You can notice that, by using the technical solution of the present invention, in the first number of subframes of the first base station, the UE is able to not listen to signals on the PDCCH of the serving cell in the administration area of the second base station, and the like, thereby effectively reducing consumption energy UE.

[0081] In this embodiment of the present invention, in cases where the bitmap attribution of the subframes has not changed, the first base station does not need to be instructed that the UE switches the state in the subframe that corresponds to the first number of subframes and in the subframe of each frame, but it instructs the UE to switch the state only in the subframe, which corresponds to the first number of subframes and is a subframe of the accurately described frame. By using the above technical solution, in each subframe that corresponds to the first number of subframes in which the first base station transmits the first data, the transceiver corresponding to the second base station is turned off in the UE, thereby further reducing energy consumption of the UE and improving signal quality, received by the UE.

[0082] After the first base station receives the second data allocation information corresponding to the second base station, the first base station transmits the second data allocation information to the second base station. Optionally, the first base station transmits the second data allocation information to the second base station only when the first base station determines that a predetermined condition is satisfied. Specifically, in cases where the first base station determines that the bitmap attribution map of subframes has not changed, and the current subframe is not a subframe that corresponds to the first number of subframes and is a subframe of a precisely described frame in the elementwise attribution map of subframes, the first base station allocates a second number subframes to a second base station; in cases where the first base station determines that the bitmap attribution map of subframes has changed, and the current subframe is not a subframe that corresponds to the updated first number of subframes and is a subframe of the accurately described frame in the updated bitmap attribution map of the subframes, the first base station allocates an updated second number subframes to the second base station. Alternatively, in cases where the first base station determines that the bitmap attribution of the subframes has not changed, and the current subframe is not a subframe that corresponds to the first number of subframes and is a subframe of the first frame, after a time point corresponding to the effective data allocation time, the first base the station allocates a second number of subframes to the second base station; in cases where the first base station determines that the bitmap attribution map of the transmission subframes has changed and the current subframe is not a subframe that corresponds to the updated first number of subframes and is a subframe of the first frame, after a point in time corresponding to the effective data allocation time, the first base station allocates an updated second number of subframes to the second base station. You may notice that the first base station can transmit the bitmap attribution card for transmission subframes only when the first base station determines that downstream data transmitted simultaneously by multiple base stations within the TTI can exceed the radio reception power of the UE. For example, the UE aggregates two serving cells in the administration area of the first base station, and two serving cells in the administration area of the second base station. In cases where the wireless conditions of the cells are favorable for a UE of category 6 power, then the data transmitted simultaneously by the first base station and the second base station to the user equipment of the UE may exceed the radio access power of the UE; in cases where the wireless conditions of the serving cells are lower than a predetermined threshold value, the data transmitted simultaneously by the first base station and the second base station to the user equipment of the UE cannot exceed the radio reception power of the UE. Therefore, by using the above-mentioned technical solution, the first base station transmits the second data allocation information to the second base station only when the predetermined condition is satisfied, thereby effectively reducing signaling exchange between devices and reducing system consumption.

[0083] The first base station may also transmit second data allocation information, which includes both a data allocation threshold and data allocation timing information, to the second base station. Specifically, the first base station allocates a third subframe number and a first MIMO mode to a first base station, allocates a fourth subframe number and a second MIMO mode to a second base station, and transmits second data allocation information, which includes a fourth subframe number, and a second MIMO mode to the second base station, the MIMO mode being the maximum number of supported layers for spatial downlink multiplexing. The third number of subframes and the fourth number of subframes may be the same (for example, as the third numbers of transmission subframes and the fourth numbers of transmission subframes are from 0 to 4), or may be different (for example, the third numbers of subframes of the transmission are from 0 to 4, and the second numbers of transmission subframes are from 4 to 6).

[0084] Step 310: the first base station instructs the second base station to transmit, in accordance with the second data allocation information, which is determined in accordance with the radio access power of the UE, data to the UE.

[0085] In this embodiment of the present invention, when the data allocation information includes an effective data allocation time, the first base station instructs the second base station to transmit, in accordance with the second data allocation information, the second data to the UE, at a time corresponding to effective data allocation time.

[0086] In step 300, in the first subframe number of the first base station, the UE switches, in the serving cell within the administration area of the second base station, to an inactive discontinuous reception state; Similarly, in the second subframe number of the second base station, the UE switches, in the serving cell within the administration area of the first base station, to an inactive discontinuous reception state. In the subframe corresponding to the second subframe number, the UE is able to not listen to signals on the PDCCH of the serving cell in the administration area of the first base station and the like, and the transceiver corresponding to the first base station is turned off in the UE, thereby effectively reducing power consumption UE

[0087] In the above process, the second base station transmits the second data directly to the UE, in accordance with the data allocation information. In order to ensure the accuracy of the process of forming carrier aggregation among base stations, optionally, the first base station transmits a measurement report to the second base station, and instructs the second base station to update, in accordance with the measurement report, the second data allocation information; and the first base station receives updated second data allocation information transmitted by the second base station. The process of obtaining a measurement report at the second base station is as follows: send, from the first base station to the second base station, a measurement report received by the first base station; or receive, at a second base station, a measurement report that is reported by the user equipment of the UE.

[0088] In this embodiment of the present invention, the UE receives and receives the data rate of the first base station and the data rate of the second base station, and, in cases where the UE determines that the absolute value of the difference between the data rate the first base station and the data rate of the second base station, greater than the predetermined threshold value, the UE transmits data rate control information that is generated based on the feedback information of the hybrid about an automatic repeat request (automatic repeat request, HARQ), or based on a radio link control status report (radio link control, RLC), to the first base station, and to the second base station. The first base station receives data rate control information transmitted by the user equipment of the UE, and adjusts, in accordance with the data rate control information, the data rate to the UE. For example, the data rate of the first base station is a1, the data rate of the second base station is a2, and al> a2. In cases where al-a2> a (the value of a is a predetermined threshold value), the first base station decreases the data rate in accordance with the data rate control information, as shown in FIG. 6.

[0089] Referring to FIG. 7, in an embodiment of the present invention, a detailed transmission process, by a second base station, of data to a UE, as indicated by the first base station, is as follows:

[0090] Step 700: The second base station receives data allocation information, which is determined by the first base station, in accordance with the radio access power of the UE.

[0091] In this embodiment of the present invention, the data allocation information includes a data allocation threshold and / or data allocation timing information. The first base station aggregates carriers together with the second base station.

[0092] Step 710: The second base station transmits data to the UE, in accordance with the data allocation information.

[0093] In this embodiment of the present invention, the total amount of data that is transmitted by the first base station and the second base station to the user device UE in the same TTI does not exceed the total amount of data that can be received in accordance with radio access power of the UE. If the data allocation information includes an effective data allocation time, then the second base station transmits, in accordance with the data allocation information, data to the UE, at a time corresponding to the effective data allocation time.

[0094] The second base station receives, in accordance with the data allocation information, a data allocation threshold value and / or data allocation time matching information allocated to the second base station.

[0095] In the above process, the second base station receives, in accordance with the data allocation information, one, or any combination, of the following parameters as the data allocation threshold: the maximum number of bits of DL-SCH transport blocks received within the TTI, after allocation, the maximum number of bits of the DL-SCH transport block received within the TTI, after allocation, the total number of soft channel bits, after allocation, the maximum number of levels supported for spatial mult pleksirovaniya downlink after selection, and maximum number of PDCP SDUs protocol within the TTI, after isolation.

[0096] If the data allocation information includes data allocation timing information, then the second base station transmits, according to the subframe information that is carried in the data extraction information, data to the UE in the corresponding subframe included in the information about subframes. If the data allocation information includes data allocation time matching information and a data allocation threshold, then the second base station transmits, according to the information of the subframes, and with the MIMO mode, which are carried in the data allocation information, the data to the UE, in the corresponding subframe included in the subframe information in accordance with the MIMO mode.

[0097] Optionally, the second base station transmits a bitmap attribution card for the subframes to the UE, and instructs the UE to switch in accordance with the effective data allocation time and the bitmap attribution map of the subframes, and in the subframe corresponding to the number of subframes for the data that are transmitted by the second base station to an inactive discontinuous reception state in the serving cell within the administration area of the first base station. If the data allocation information further includes an effective data allocation time, then the second base station transmits the bitmap attribution card of the subframes, and the effective data allocation time, to the user equipment of the UE, and instructs the UE to switch according to the effective time data allocation, and with the card of bitwise attribution of subframes, and in a subframe that corresponds to the number of subframes for data transmitted by the second base station, and is a frame subframe, respectively which indicates the effective time of data allocation to the inactive state of discontinuous reception in the serving cell within the administration area of the first base station, while the bitmap attributing subframes for data transmissions includes the number of subframes corresponding to the data transmitted by the first base station and the number of subframes, corresponding to data transmitted by the second base station.

[0098] In the above process, the second base station directly transmits data to the UE in accordance with the data allocation information. In order to ensure the accuracy of the process of forming carrier aggregation among base stations, optionally, the second base station receives, in accordance with the measurement report of the UE, data allocation information that is generated locally; in cases where the second base station determines that the data allocation information transmitted by the first base station is different from the data allocation information that is generated locally, the second base station transmits, to the first base station, data allocation information that is allocated locally, and it dictates that the first base station update, in accordance with the data allocation information that is allocated locally, the data allocation information that was transmitted before the first base station to about the second base station.

[0099] In particular, the second base station receives data rate control information that is transmitted by the user equipment of the UE, and which is generated based on the HARQ feedback information, or based on the RLC status report, and adjusts in accordance with the transmission rate control information data rate for transmitting data to the UE.

[0100] Referring to FIG. 8, in an embodiment of the present invention, a detailed process for receiving data at a UE, in accordance with downstream resources allocated by the first base station and the second base station, is as follows: [0101] Step 800: The UE receives the first data that is transmitted by the first base station in accordance with the first data allocation information.

[0102] In this embodiment of the present invention, the first data allocation information includes a data allocation threshold and / or data allocation timing information.

[0103] In cases where the first data allocation information includes a data allocation threshold, the UE receives an appropriate amount of data that is transmitted by the first base station in accordance with the data allocation threshold; in cases where the first data allocation information includes time allocation information of data allocation, the UE receives data that is transmitted by the first base station in a subframe corresponding to a first subframe number included in the data allocation time matching information.

[0104] Optionally, in the subframe corresponding to the first number of subframes, the UE switches to an inactive discontinuous reception state in a serving cell that is administered by the second base station, thereby effectively reducing power consumption of the UE.

[0105] Step 810: The UE receives second data that is transmitted by the second base station in accordance with the second data allocation information.

[0106] In this embodiment of the present invention, the first base station aggregates the carriers together with the second base station, and the total amount of the first data transmitted by the first base station and the second data transmitted by the second base station, which is received by the UE, in one and the same TTI, does not exceed the total amount of data that can be received by the UE, in accordance with the radio access power of the UE.

[0107] The second data allocation information is transmitted, by the first base station, to the second base station. The user equipment UE receives second data that is transmitted by the second base station in a subframe corresponding to a second subframe number included in the second data allocation time matching information.

[0108] Optionally, in the subframe corresponding to the second subframe number, the UE switches to an inactive discontinuous reception state in a serving cell that is administered by the first base station, thereby effectively reducing energy consumption of the UE.

[0109] In particular, the UE obtains a first data rate corresponding to a first base station and a second data rate corresponding to a second base station; and in cases where the UE determines that the absolute value of the difference between the first data rate and the second data rate is greater than a predetermined threshold value, the UE transmits data rate control information that is generated based on the HARQ feedback information, or based on the RLC status report, to the first base station, or to the second base station, and the UE directs the first base station, or the second base station, to control the data rate. In this embodiment of the present invention, the data rate may be determined in accordance with a sequence number corresponding to the data block.

[0110] Referring to FIG. 9, in an embodiment of the present invention, a detailed data transfer process is as follows:

[0111] Step 900: The first base station determines first data allocation information used by the first base station to transmit the first data to the UE, and determines second data allocation information used by the second base station to transmit the second data to the UE.

[0112] In this embodiment of the present invention, the data allocation information includes a data allocation threshold and / or data allocation timing information, and the data extraction information further includes an effective data extraction time.

[0113] The data allocation threshold may include any or a combination of the following parameters: maximum number of DL-SCH transport block bits received within the TTI, maximum number of DL-SCH transport block bits received within the TTI, total soft channel bits, the maximum number of supported layers for downlink spatial multiplexing, and the maximum number of PDCP SDUs within TTI.

[0114] The time allocation information of the data allocation is information about subframes, and includes: at least one first number of subframes and at least one third number of subframes of the first base station, and at least one second the number of subframes and at least one fourth number of subframes of the second base station.

[0115] Step 910: The first base station transmits the first data to the UE, in accordance with the first data allocation information.

[0116] In this embodiment of the present invention, if the first data allocation information is a data allocation threshold, then the first base station transmits, according to the data allocation threshold, a data amount that does not exceed a data amount corresponding to the data allocation threshold to the UE. If the second data allocation information is data allocation time matching information, then the first base station transmits, in a subframe corresponding to the first subframe number of the first base station, in the data allocation time matching information, the first data to the UE. If the first data allocation information is data allocation time matching information and a data allocation threshold, then the first base station transmits, in a subframe corresponding to a third subframe number of the first base station, in the data allocation time matching information, the first data to the UE, according to the first MIMO mode.

[0117] Optionally, in the subframe corresponding to the first number of subframes, the UE switches to an inactive discontinuous reception state in the serving cell within the administration area of the second base station.

[0118] In particular, the first base station receives data rate control information transmitted by the UE, and adjusts, in accordance with the data rate control information, the rate for transmitting data to the UE.

[0119] Step 920: The second base station transmits second data to the UE, in accordance with the second data allocation information.

[0120] In this embodiment of the present invention, in which the data allocation information includes an effective data allocation time, the second base station can transmit data to the UE at a time corresponding to the effective data allocation time, thereby ensuring that the first basic the station, and the second base station, transmit data to the UE at the appointed time, and facilitating coordination, at the first base station, of allocating data between multiple base stations. [0121] If the data allocation information is a data allocation threshold, then the second base station transmits, to the user device UE, in accordance with the data allocation threshold, a data amount that does not exceed the data amount corresponding to the data allocation threshold. If the data allocation information is the time allocation information of the data allocation, then the second base station transmits, in the subframe corresponding to the second subframe number of the second base station, the second data to the UE in the data allocation time agreement information. If the data allocation information includes data allocation time matching information and a data allocation threshold, then the second base station transmits, in the subframe corresponding to the fourth subframe number of the second base station, data to the UE, in the data allocation time matching information, to according to the second MIMO mode.

[0122] Optionally, in the subframe corresponding to the second number of subframes, the UE switches to an inactive discontinuous reception state in a serving cell within the administration area of the first base station.

[0123] In particular, the second base station receives data rate control information transmitted by the user equipment of the UE, and adjusts, in accordance with the data rate control information, the speed for transmitting data to the UE.

[0124] A detailed data transfer process is described in detail hereinafter, with reference to a specific application scenario, and by using an example in which a carrier aggregation generation system among base stations includes a first base station and a second base station, and the UE represents is a category 6 UE user device in Table 1.

[0125] The method of embodiment 1:

[0126] The first base station receives, in accordance with a measurement report that is reported by the user equipment of the UE, the first data allocation information used by the first base station to transmit the first data to the UE, and the second data extraction information used by the second base station to transmit the second data to the UE, and the data allocation information includes only the data allocation threshold value. Turning to FIG. 10, a detailed data transfer process is as follows:

[0127] Step 1000: the first base station receives first data allocation information that is allocated to the first base station and includes a data allocation threshold, and transmits a data amount that observes the first data allocation information to the UE.

[0128] Step 1010: the first base station transmits second data allocation information, which includes a data allocation threshold, to the second base station.

[0129] In this embodiment of the present invention, the UE corresponds to the category 6 UE user device in Table 1. Referring to Table 1, it can be understood that the radio access power parameter corresponding to the UE is: the value of the “301504” parameter of the maximum number of bits of transport blocks DL-SCH taken within the TTI. The first base station separates the radio access power parameter of the UE, for example, separating the radio access power parameter based on the fact that the data volumes corresponding to the first base station and the second base station are the same, and then the first base station and the second base station each receive the value of parameter 150752. The first base station uses parameter 150752 of the maximum number of bits of the DL-SCH transport blocks as a data allocation threshold value, and transmits a data allocation threshold value to Torah base station. In this case, even if multiple serving cells and multiple levels of MIMOs are generated for the first base station, or for the second base station, and the actual transmit power of the first base station or second base station exceeds 150752, the maximum number of bits of the DL- transport blocks The SCHs that the first base station, or second base station, transmits to the UE, within any TTI, must be less than, or equal to, 150752.

[0130] In addition, the maximum number of supported layers for spatial downlink multiplexing can also be used as a data allocation threshold. For example, for a UE whose UE Power Category is 6, the value of the parameter “maximum number of supported levels for spatial multiplexing in the downlink” is 4. The first base station divides the value of the parameter “maximum number of supported levels”, for example, by dividing, wherein the first base station and the second base station share the value of the parameter “maximum number of supported levels” in equal shares; then the first base station and the second base station each receive 2 levels, and the first base station uses the value of the parameter 2 “maximum number of supported levels” for spatial multiplexing in the downstream channel, as the threshold value of data allocation, and transmits the threshold allocation value data to the second base station. In this case, even if the value of the “maximum number of supported levels” parameter of the first base station and the second base station is 4, the maximum number of supported levels for downlink spatial multiplexing, which the first base station or the second base station transmits to the UE , within any TTI, should be less than or equal to 2.

[0131] Optionally, multiple UE radio access power parameters can be used as a data allocation threshold at a time, so as to ensure that the UE radio access power is not exceeded. In this case, the data allocation threshold allocated by the first base station must comply with all of the multiple radio access power parameters of the UE.

[0132] Step 1020: the second base station receives the second data allocation information, obtains a data allocation threshold value that is carried in the second data allocation information, and transmits a data amount that observes the data allocation threshold value to the UE.

[0133] In this embodiment of the present invention, the second base station receives, in accordance with the measurement report of the UE, the third data allocation information that is generated locally; in cases where the second base station determines that the first data allocation threshold, which is obtained in accordance with the data allocation information, and which is transmitted by the first base station, is different from the data allocation threshold that is generated locally, the second base station transmits to the first base station, the third data allocation information that is generated locally, and it requires the first base station to update the second data allocation information, in accordance with the third its data allocation information that is allocated locally; and the second base station receives the updated second data allocation information, and it transmits data to the UE, in accordance with the updated second data allocation information.

[0134] The method of embodiment 2:

[0135] The first base station receives, in accordance with a measurement report that is reported by the user equipment of the UE, the first data allocation information used by the first base station to transmit data to the UE, and the second data extraction information used by the second base station to transmit data to the UE , and the data extraction information includes matching information on the time of data allocation, and the effective time of data extraction. Turning to FIG. 11, a detailed data transfer process is as follows:

[0136] Step 1100: In accordance with the data allocation time matching information that is carried in the first data allocation information and which is allocated to the first base station, the first base station transmits the first data to the UE in a subframe corresponding to the first subframe number, and it instructs the UE to switch, in the subframe corresponding to the first number of subframes, to an inactive discontinuous reception state in the serving cell within the administration area of the second base station.

[0137] Step 1110: The first base station transmits second data allocation information, which includes data allocation time matching information, and an effective data allocation time, to the second base station.

[0138] In this embodiment of the present invention, the first base station receives a bitmap attribution card of subframes, in accordance with the first subframe numbers (such as 1, 4 and 7) and the second subframe numbers (such as 2, 3 and 8) that are carried in the data allocation time matching information, uses the bitmap attribution map of subframes, and the effective data allocation time, as the second data extraction information, and transmits the second data extraction information to the second base station.

[0139] In this embodiment of the present invention, the effective data allocation time can be represented as (frame number of the absolute time information system SFN) + (number of subframes) subframe.

[0140] The data allocation timing agreement information changes, together with changes in load, wireless conditions, data partitioning algorithms, and traffic control situations that correspond to a serving cell within the administration area of the first base station and a serving cell within the administration area of the second base station . In cases where the first base station determines that the data allocation timing information has changed, the first base station must transmit updated data allocation timing information to the second base station.

[0141] Step 1120: The second base station receives the second data allocation information, obtains data allocation timing information that is carried in the second data extraction information, transmits the second data to the UE, in a subframe corresponding to the second subframe number, and instructs that The UE switched, in the subframe corresponding to the second number of subframes, to an inactive discontinuous reception state in a serving cell that is administered by the first base station.

[0142] In this embodiment of the present invention, in cases where the UE is to receive the first data transmitted by the first base station, the transceiver corresponding to the second base station is turned off, or the serving cells serving the second base station are deactivated; similarly, when the UE receives only the second data transmitted by the second base station, the transceiver corresponding to the first base station is turned off, or the serving cells serving the first base station are deactivated. In cases where the UE must again receive data transmitted by the first base station or the second base station, serving cells in the administration area of the first base station, or serving cells in the administration area of the second base station, are activated. Switching the UE to an inactive discontinuous reception state means: as for serving cells in the administration area of the first base station, the UE receives downstream data in accordance with the same DRX rule, for example, while listening to signals, or not listening to signals, on the physical a downlink control channel in serving cells that are administered by the first base station; as for serving cells in the administration area of the second base station, the UE receives downstream information in accordance with the same DRX rule, for example, while listening to signals, or not listening to signals, on the PDCCH in the serving cells that are administered by the second base station; as for the first base station and the second base station, the UE may receive downstream information without adhering to the same DRX rule, for example, the UE listens for signals on the PDCCH in serving cells that are administered by the first base station, and does not listen for signals on the PDCCH in serving cells that are administered by a second base station.

[0143] The method of embodiment 3:

[0144] The first base station receives, in accordance with a measurement report that is reported by the user equipment of the UE, the first data allocation information used by the first base station to transmit data to the UE, and the second data allocation information used by the second base station to transmit data to the UE , and the data extraction information includes data allocation timing information and a data allocation threshold. Turning to FIG. 12, a detailed data transfer process is as follows:

[0145] Step 1200: in accordance with the data allocation time matching information that is carried in the first data extraction information, the first base station transmits the first data to the UE in a subframe corresponding to the third subframe number in accordance with the first MIMO mode.

[0146] Step 1210: the first base station transmits second data allocation information, which includes data allocation timing information and a data allocation threshold, to the second base station.

[0147] In this embodiment of the present invention, the first base station receives a subframe bitmap in accordance with third subframe numbers (such as 0 to 3) and fourth subframe numbers (such as 0 to 3), which are transferred to the time allocation information of the data allocation, the first MIMO mode (such as 3 levels) allocated to the first base station is received, and the second MIMO mode (such as 1 level) allocated to the second base station uses a bitmap subframes, and a data allocation threshold, as data allocation information, and transmits data allocation information to a second base station.

[0148] Step 1220: The second base station receives second data allocation information, obtains data allocation timing information that is transferred to the second data extraction information, and transmits second data to the UE, in a subframe corresponding to a fourth subframe number, in accordance with a second MIMO mode.

[0149] The method of embodiment 4:

[0150] The first base station receives, in accordance with a measurement report that is reported by the user equipment of the UE, the first data allocation information used by the first base station to transmit data to the UE, and the second data allocation information used by the second base station to transmit data to the UE . Turning to FIG. 13, a detailed control process by the first base station and the second base station for transmitting data, in accordance with the result of determining the data rate of the user device UE, is as follows:

[0151] Step 1300: the UE receives the first data transmitted by the first base station, and obtains a first data rate corresponding to the first data.

[0152] Step 1310: The UE receives second data transmitted by the second base station and obtains a second data rate corresponding to the second data.

[0153] Step 1320: the UE compares the first data rate and the second data rate, and transmits data rate control information to the first base station and the second base station, in accordance with the comparison result.

[0154] In this embodiment of the present invention, the data rate is obtained by using the sequence number of the received data block. By using the RLC PDU partition, as an example, specifically, unbalanced wireless resource scheduling results in relatively large differences in the serial numbers of RLC PDUs transmitted by different base stations (i.e., the difference between the sequence numbers is relatively large), and therefore the UE needs in a larger RLC transmit window, and / or in a larger RLC receive window. As shown in FIG. 5, with regard to downstream data reception, the UE determines the distance between the maximum sequence numbers of the RLC PDUs transmitted by the first base station and the second base station in a predetermined time period; in cases where the distance is greater than a predetermined threshold, the UE transmits data rate reduction information to a base station that transmits RLC PDUs at high speed and / or transmits data rate increase information to a base station that transmits Reduced speed RLC PDUs. The term “data rate” may refer to the number of RLC PDUs, or to the amount of downstream data transmitted by the physical layer, such as the number of bits.

[0155] Step 1330: the first base station receives data rate control information, and adjusts the data rate in accordance with the data rate control information.

[0156] Step 1340: the second base station receives the data rate control information, and adjusts the data rate in accordance with the data rate control information.

[0157] By using the aforementioned technical solution, the data rate of the RLC PDUs corresponding to one or more base stations can be accelerated or slowed down so that the receiving RLC window or the RLC order recovery window corresponding to the UE is reduced in size, thereby reducing pressure on the “full size buffer level 2”.

[0158] Based on the above technical solutions, referring to FIG. 14, the present invention provides a base station including a transmission module 140 and a indicating module 141.
