Technical field

Embodiments of the present invention relate to the field of communications technologies, and in particular, to a carrier frequency control method and apparatus in a multi-carrier/cell system. Background technique

The existing HSPA (High-Speed Packet Access) system is carried at a single frequency point, in order to further improve the data transmission rate of the HSPA system, reduce the delay and thereby improve the user experience, A scheme of bundling for carrying HSPA data is proposed. In this scheme, two (or more) 5 MHz carrier frequencies in the downstream direction will be bundled together for transmission of HSPA data. The most important one is to bundle two carrier frequencies. The two carrier frequencies can be regarded as the frequency points used by the two cells covering the same area, and the number of carrier frequencies used in the uplink and downlink. They may be the same or different, but generally the number of downlink carrier frequencies is more than the number of uplink carrier frequencies. Such a system for bundling multiple carrier frequencies for transmitting HSPA data is generally used: 2 carrier frequencies for downlink, 2 carrier frequencies for uplink, 2*2 mode; or 2 carrier frequencies For downlink, 1 carrier frequency is used for uplink, which is called 2*1 mode, and regardless of which mode involves the problem of using 2 carrier frequencies in the downlink. A multi-carrier/cell can support multiple carrier frequencies, and the cells corresponding to these carrier frequencies generally have a certain correlation in geographic location. There are two methods for defining a multi-carrier/cell. One is a special cell different from the original single carrier/cell. This cell has its own cell ID, which supports multiple carrier frequencies. Second, it refers to a set of cells. Concept, each cell in the set is an independent individual like the original single carrier/cell, their cell

IDs can be the same or different.

Introduce the concept of the main carrier frequency. If only one carrier frequency is used for uplink or downlink, then this frequency is used as the primary carrier frequency. If there is a service on the uplink and downlink, it is carried on the DCH (Dedicated Channel), and the frequency of the DCH is used as the primary carrier frequency. If both the uplink and the downlink use two carrier frequencies and no service is carried on the DCH, the RNC (Radio Network Controller) reports the 2a event reported by the UE (User Equipment). The main carrier frequency is changed. After each main carrier frequency change, the RNC (Radio Network Controller) sends a new measurement control message to inform the UE of the frequency used for the same-frequency switching measurement.

The UE only determines the trigger of the lx/2x event according to the primary carrier frequency, but needs to carry the information of the two frequency points when reporting the measurement report, and the network side needs to comprehensively consider when determining whether to add the cell to the active set (especially when the Id event is triggered). The signal quality of the two carrier frequencies.

In the above description, the measurement event of the carrier frequency/cell for the non-primary carrier frequency uses an inter-frequency event such as a 2x event, and the lx event is used for the carrier frequency/cell measurement event of the carrier frequency. For example: The primary carrier frequency corresponds to carrier frequency A, cells 1 and 2; the non-primary carrier frequency corresponds to carrier frequency B, cells 3 and 4. Then, 2a, 2b, 2c, 2d are used for the measurement events of cells 3 and 4. The la, lb, lc, Id events are used for cells 1 and 2.

In the process of implementing the present invention, the inventors have found that the prior art has at least the following problems: The above method can be used for data transmission using multiple carriers/cells, but the environment of the user terminal may change at any time, and correspondingly, the carrier frequency The quality may also change, but the existing technical solutions do not provide a method for carrier frequency adjustment based on carrier frequency quality changes, which affects the optimization of network quality.

Optimize network quality and improve user experience.

The specific embodiments of the present invention are further described in detail below with reference to the accompanying drawings and embodiments.

As shown in FIG. 1 , it is a schematic flowchart of a carrier frequency control method in a multi-carrier/cell system according to Embodiment 1 of the present invention, which includes the following steps:

Step S101: Establish a multi-carrier/cell connection between the terminal UE and the network.

Multi-carrier/cell connectivity is established with two downlink carrier frequencies and one or two upstream carrier frequencies.

When the multi-carrier/cell connection is established by using two downlink carrier frequencies and one uplink carrier frequency, an F-DPCH (Flocked Dedicated Physical Channel) is established on the downlink carrier frequency corresponding to the uplink carrier frequency. Power control of the uplink physical channel, and data transmission by HS-DSCH (High-Speed Down Share Channel); data transmission by HS-DSCH on the remaining downlink carrier frequencies.

For a detailed description of this step and an additional field that needs to be written into each signaling, refer to the second embodiment of the present invention.

Step S102: The RNC sends a carrier frequency deactivation, an activation condition, and a carrier frequency reporting condition to the Node B.

Specifically, the conditions of the deactivation threshold, the activation threshold, and the carrier frequency are

Step S103: The RNC forwards the carrier frequency to the terminal UE via the Node Node B.

The terminal UE receives the carrier frequency reporting condition sent by the RNC forwarded by the Node B, and the carrier frequency reporting condition specifies the measured signal quantity, when to start measurement, when to stop measurement, the measurement condition, and the time of the measurement result.

Step S104: The Node B feeds back the response information to the RNC.

It should be noted that the order between steps S103 and S104 can be exchanged, and the order change does not affect the protection scope of the present invention. Step S105: The terminal UE forwards the response information to the RNC via the Node B. Step S106: The terminal UE reports the CQI (Channel Quality Indicator) information of the carrier frequencies A and B that meet the carrier frequency reporting condition to the Node B.

The reporting method includes: transmitting a CQI information by using a MAC (Media Access Control) PDU (Protocol Data Unit) to report the CQI information; or transmitting the CQI information through the physical layer signaling.

Step S107: The Node B compares the CQI information with the deactivation threshold, determines that the carrier frequency B quality is lower than the deactivation threshold, and determines to deactivate the carrier frequency B.

Step S108: The Node B sends an instruction to deactivate the carrier frequency B to the terminal UE to deactivate the carrier frequency B.

The sending method of the foregoing instruction includes: a deactivation instruction carried by the MAC control PDU, or a deactivation instruction carried by the physical layer signaling.

Step S109: The terminal UE sends the feedback of the deactivated carrier frequency B to the Node B.

Step S110: The terminal UE reports the CQI information of the carrier frequencies A and B that meet the carrier frequency reporting condition to the Node B.

The reporting method includes: reporting the CQI information by using the MAC control PDU; or transmitting the CQI information by using physical layer signaling.

In this step, the carrier frequency B has been deactivated, but since it still belongs to the carrier frequency of the carrier frequency reporting condition, its CQI information is still reported.

Steps Sl l l and Node B compare the CQI information and the activation threshold, determine that the carrier frequency B quality is higher than the activation threshold, and determine to activate the carrier frequency B.

Step S112: The Node B sends an instruction to activate the carrier frequency B to the terminal UE, and activates the carrier frequency B.

The carrier frequency B is activated by the activation command carried by the MAC control PDU; or the carrier frequency B is activated by the activation instruction carried by the physical layer signaling.

Step S113: The terminal UE sends the feedback of the activated carrier frequency B to the Node B.

It should be further noted that when the step S102 of the embodiment only sends the deactivation threshold and the carrier frequency condition, the steps S101 to S109 constitute a carrier frequency deactivation process; when the step S102 of the embodiment only sends the activation threshold and Steps S101 to S105 when the carrier condition is 4艮 And S110 to S113 constitute a carrier frequency activation process. Such variations are also within the scope of the invention.

The technical solution of the embodiment of the present invention has the following advantages: the base station Node B is used as a control center, and a certain carrier frequency is flexibly activated and deactivated, the system capacity is improved, and the load balancing effect is better.

Embodiment 2

In order to explain the technical solution of the present invention in detail, as shown in FIG. 2, the multi-carrier/cell connection between the terminal UE and the network will be described below through the second embodiment of the present invention.

A cell with multi-carrier/cell capability will broadcast its own multi-carrier/cell capability or multi-carrier/cell cooperation capability. For example, Node B configures 3 frequency points, 2 cells per frequency point, and these cells are different. The cells of the carrier frequency can cooperate. The terminal UE with multi-carrier/cell capability reports its own capability in the RRC (Radio Resource Control) connection establishment request (in the embodiment, the RRC connection setup request message is taken as an example), and the network UTRAN receives the terminal UE. The RRC connection setup request message simultaneously knows the multi-carrier/cell capability of the terminal UE and the service type roughly requested by the terminal UE, and it can assign the terminal UE to use the multi-carrier/cell in the RRC connection setup message. Receive capability and or multi-carrier/cell transmission capability.

When the terminal UE is already in the connected state, the terminal UE or the network initiates a new service, the network knows that both the terminal UE and the cell have multi-carrier/cell capabilities, so the network can notify the terminal UE to use the multi-carrier through various reconfiguration messages. /cell reception capability and or multi-carrier/cell transmission capability. The UTRAN can configure a corresponding UEID for each carrier/cell usage. For example, the terminal UE can use two downlink carriers/cells for one uplink carrier/cell, and the terminal UE should have two H-RNTIs (HS-DSCH Radio Network Identifier), 1 Primary E-RNTI (Primary Enhanced Radio Network Identifier). The terminal UE uses two 2 downlinks and two uplinks: The terminal UE should have 2 H-RNTIs and 2 Primary E-RNTIs.

The network establishes multi-carrier/small through multiple downlink carrier frequencies and multiple uplink carrier frequencies and terminals. For the area connection, the number of downlink carrier frequencies is greater than or equal to the number of uplink carrier frequencies. For example, if the multi-carrier/cell connection is established by M downlink carrier frequencies and N uplink carrier frequencies, and M is greater than N, it corresponds to the uplink carrier frequency. The F-DPCH (partial dedicated physical channel) is established on the N downlink carrier frequencies to perform power control of the uplink physical channel, and data transmission is performed through the HS-DSCH (High Speed Downlink Shared Channel), and the HS is passed through the remaining MN downlink carrier frequencies. -DSCH for data transmission. For example: If the terminal UE has only one uplink carrier/cell used, the data transmission is performed on the HS-DSCH at both downlink frequencies. And the F-DPCH can be established to perform power control of the uplink physical channel only on the corresponding downlink frequency point, and the other downlink frequency point has no corresponding uplink physical channel, so only the HS-DSCH is used instead of establishing power control for the uplink. Downlink physical channel.

Establishing a multi-carrier 3⁄47 cell connection between the UE and the network includes the following steps: Step s201: The network receives multi-carrier/cell capability information sent by the terminal.

More specifically, after receiving the capability information of the terminal, the network sends feedback information to the terminal. Step s202: The network establishes a multi-carrier/cell connection.

More specifically, after the network establishes a multi-carrier/cell connection, the method further includes:

Step s203: The network configures a corresponding terminal identifier for each multi-carrier/cell.

The technical solution of the embodiment of the present invention flexibly activates and deactivates a certain carrier frequency, improves system capacity, and better performs load balancing.

Table 1-5 specifically lists information elements in the message indicating that the terminal UE uses multi-carrier/cell reception capability and or multi-carrier/cell transmission capability. The following table is only a specific example, based on the technical idea of the present invention The modifications made to the table do not affect the scope of protection of the embodiments of the present invention.

As shown in FIG. 3, the third step of the present invention provides a detailed description of the process of determining the deactivated carrier frequency, including the following steps:

Step S301: The terminal UE receives the carrier frequency reporting condition.

This message specifies the measured semaphore, when to start the measurement, when to stop the measurement, the conditions of the measurement, and the time of the measurement.

Step S302: The terminal UE reports the CQI information of the carrier frequency to the Node B.

In this step, it should be specified that the measurement value of the deactivated carrier/cell of the terminal UE is reported to the NodeB method and the NodeB can obtain the quality and power of the radio link of a certain carrier/cell through which measurements. Currently, the terminal UE reports the CQI in the HS-DPCCH (High-Speed Dedicated Physical Control Channel), and this value can be used as the input of the decision by the NodeB. The NodeB receiver can report the received BLER value to the NodeB scheduler for the NodeB to make a decision.

Step S303: The Node B compares the CQI information and the deactivation threshold to determine whether to deactivate the carrier frequency. The deactivation threshold includes the following: The carrier/cell signal quality is below a threshold (EC/NO); and or the carrier/cell signal power (RSCP) is below a threshold; and or transmitted over the carrier/cell The block error rate (BLER) of the data is above a threshold; and or the power of the data transmission on the carrier/cell is above a threshold; and or the number of retransmissions of data on the carrier/cell is above a threshold; and or The synchronization of a link between the NodeB and the terminal UE is lost. The duration of the above conditions may be that the time must be maintained The length can be judged, or it can be made immediately, depending on the purpose and requirements of the UTRAN for each carrier/cell. This condition is that the RNC notifies the NodeB that the terminal UE does not have to know. The method for the RNC to notify the NodeB is to add a dedicated signaling on the lub interface, or carry it in the message that the radio link establishes reconfiguration.

S304. The Node B sends an instruction to deactivate the carrier frequency to the UE to deactivate the carrier frequency. The following steps further describe the steps to deactivate the carrier frequency, including the following steps:

Step 1. Node B decides to deactivate a carrier frequency;

Step 2: The Node B sends an instruction to deactivate the carrier frequency to the terminal UE to deactivate the carrier frequency.

After the Node B makes a judgment, the terminal UE is notified to deactivate a certain carrier/cell. Specifically, the following two methods are included:

Method A. As shown in FIG. 4 and FIG. 5, the terminal UE is notified by the MAC control PDU field. The fields included in the MAC Control PDU are described as follows:

The C/T is a PDU indicator bit, which is used to indicate whether the PDU is a control PDU or a data PDU; the carrier frequency control item is used to indicate whether the PDU includes a carrier frequency control item;

The signal quality item is used to indicate whether the PDU includes a signal quality CQI report item; the status response item is used to indicate whether the PDU contains a status response item, such as whether there is a response to the control command received by the peer end;

The carrier frequency activation bit is used to indicate that the carrier/cell is activated/deactivated, and each carrier frequency occupies lbit; when set to 1, the carrier/cell is activated, and when the bit is set to 0, the carrier/cell is deactivated;

Signal quality content bit, including the signal quality of all carrier frequencies;

The status response content bit, for the activation/deactivation response, each carrier frequency occupies lbit. When the carrier frequency is activated/deactivated, the ACK (acknowledge character) is returned. When the carrier frequency is not activated/deactivated, a negative acknowledgement NACK (None ACKnowledge Character) is returned.

One of the control PDUs is defined as whether to use a certain downlink carrier/cell, and another is defined as whether to use an uplink carrier/cell. These two items can each occupy one bit. When the bit is set to 0, the carrier cell is used, and when the bit is set to 1, the carrier cell is not used. The number of bits that control whether the carrier/cell is deactivated is equal to the number of carriers/cells that are uplinked and downlinked, or equal to the number of carriers/cells that are used most in the downlink. The smoothness of these bits The order in which the terminal and the terminal UE receive the connection establishment or the reconfiguration message is the same.

After Node B decides to deactivate a carrier/cell, it should send the MAC Control PDU to the terminal UE, and preferentially use the downlink carrier/cell that is not deactivated to send the MAC PDU, so that the control information can be reliably received. After receiving the suspension notification, the terminal UE should respond to the Node B to indicate that the notification information is received. The response message may be in the form of HARQ (Hybrid Automatic Repeat reQuest) or MAC layer control. The PDU responds. As shown in Figure 5, it is a schematic diagram of the content of the status response item. This response should preferably be selected for the uplink carrier/cell transmission that is not deactivated.

The method and process of deactivating the carrier frequency will be further described below with reference to FIGS. 6 and 7.

The NodeB decides to deactivate a carrier/cell. For example, after the carrier/cell B is deactivated, if the carrier/cell B is a downlink carrier/cell, the NodeB will prepare to return the data transmitted by the carrier/cell B to the carrying cell. A is sent up, and if the HARQ response has been received but has not received the HARQ response of the terminal UE, the UE waits for the HARQ response of the terminal UE. If the response of the terminal UE has not been received or the response is NACK, the message is not received. The retransmission is performed on the recarrier/cell B, but the data is transferred to the carrier/cell A for retransmission. The data for retransmission should be sent preferentially on the bearer/cell A. For those packets sent from the bearer/cell B to the bearer/cell A, the data packets are sent according to the sequence number of the RLC layer of the data, instead of being directly placed in the tail of the data sequence in the bearer/cell A. . 5 is a data transmission state of two carriers/cells in which the carrier/cell B is deactivated, and FIG. 7 is a case where the data in the queue corresponding to the carrier/cell B is transferred to the carrier/cell A after the carrier/cell B is deactivated. A schematic to send. If two carriers/cells share a MAC hs/ehs queue, only the data to be retransmitted needs to be processed, and the queue transfer and insertion process is omitted.

When the NodeB decides to deactivate an uplink 3⁄47 cell, for example, if the carrier/cell C is deactivated, the NodeB shall pass the E-HCH (E-DCH HARQ Acknowledgement Indicator Channel, E-DCH). The HARQ acknowledgment indicator channel is replied to the terminal UE, and the NodeB is to receive the suspension notification. The data of the terminal UE that has been scheduled before. Then stop scheduling this carrier/cell C. After receiving the MAC Control PDU, the terminal UE performs resolving and finds that it is notifying the terminal UE to stop using a certain carrier/cell, and the terminal UE performs the following processing on the carrier/cell data:

1) When the deactivated carrier/cell is a downlink carrier/cell, the terminal UE performs CRC on the data packet (not this MAC PDU) that has been received by the deactivated carrier/cell.

(Cyclical Redundancy Check) check, if the check result is correct, it will respond to Node B ACK, and if it is wrong, it will respond to NACK. If there is no data packet to receive at this time, the carrier/cell reception and deletion of the timer and counter associated with the carrier are directly stopped.

2) When the deactivated carrier/cell is an uplink carrier/cell, the terminal UE should first use the resources that have been scheduled on the carrier/cell first, and then stop the data transmission of the carrier/cell. And the data originally prepared to be sent on this deactivated carrier/cell is transferred to another carrier/cell for transmission. For the data to be retransmitted on the deactivated cell/cell, the terminal UE needs to transmit preferentially on another carrier/cell; for the transferred data, it needs to insert another carrier/cell according to the data sequence of the radio link control protocol. Send, can not directly insert the end of the team.

On the other hand, if the cell deactivation condition of the primary carrier frequency is satisfied, and the cell is deactivated when the serving cell in the primary carrier frequency is deactivated, the Node B notifies the RNC that it cannot immediately go live and waits for the decision of the RNC. The decision of the RNC includes: deactivation, that is, the terminal UE no longer maintains any one of the wireless links; rejoining the new cell in the primary carrier frequency, and the terminal UE establishes a connection with the new cell for data transmission, and the newly added cell is the serving cell. . The auxiliary carrier frequency is replaced by the main carrier frequency.

It should be further noted that, for the carrier frequency in which only data is transmitted in the second embodiment of the present invention, since there is no corresponding uplink physical channel and the F-DPCH performs inner loop power control, the Node B cannot monitor the existing technology. The synchronization of the uplink is out of synchronization or the link is maintained, so the activation of this separate downlink frequency point is a better method by the measurement reporting of the terminal UE (2d/2c event). That is, when the 2c event is satisfied, continue Keep this carrier wireless connection, delete this connection when the 2d event occurs.

In addition to the method proposed in this embodiment, the deactivation control of the carrier/cell can be placed on the RNC, but the information of the RNC or the terminal UE is through the Node B and the lub interface between the two. This process introduces a short delay (200ms) „ and the Node B can directly obtain the signal quality and transmission quality of the radio link of each carrier/cell through the CQI reporting of the HS-DPCCH and the uplink data reception. Therefore, it is feasible to defer the carrier/cell deactivation control to the Node B and subtract the transmission time of the lub interface. Such control is more flexible and can be implemented by using physical layer signaling or MAC layer signaling.

Method B, using physical layer signaling

HS-SCCH order (High-Speed Shared Control Channel order) can be used to indicate that a certain carrier/cell of the downlink or uplink is stopped.

The E-AGCH (E-DCH Absolute Grant Channel) may be used to carry the Primary E-RNTI, and all activation bits are set to be inactive to indicate that the uplink carrier/cell is deactivated.

Because there is no corresponding response mechanism for the two physical layer signaling, in order to ensure reliability, the Node B can transmit continuously several times.

After the deactivation command is issued, the transmission processing of the original deactivated carrier/cell packet of the Node B and the terminal UE is as described in Method A.

The technical solution of the embodiment of the present invention flexibly deactivates a certain carrier frequency, improves system capacity, and better performs load balancing effects.

Embodiment 4

As shown in FIG. 8, the flow of activating the carrier frequency is described in detail by using the fourth embodiment of the present invention.

When the terminal UE performs data transmission in the multi-carrier/cell, the terminal UE always monitors the signal quality of the carrier/cell that it can use, and then performs signal quality reporting, when the terminal UE or Node B finds that it is not used. When the quality of the carrier/cell becomes better, and it becomes possible to use it to transmit data, this unused carrier and area can be added to the transmission carrier/ In the cell collection. When the new carrier frequency quality is stronger than the quality of the existing carrier frequency, the existing carrier frequency is replaced by the new carrier frequency. Steps S102 to S105 and steps S110 to S113 of FIG. Specific steps are as follows:

Step S801: The RNC simultaneously notifies the Node B and the terminal UE to perform measurement of the unused carrier/cell signal quality and the reporting strategy and the reporting result of the measurement result. The RNC informs the Node B to enable the quality threshold and data threshold for carrier/cell transmission.

Step S802: The terminal UE reports the signal quality and data volume of the pilot of the unused frequency point, and the reporting method includes: MAC control PDU, and the specific format is shown in FIG.

Step S803: The Node B compares the signal quality reported by the terminal UE with the decision threshold, and determines whether to join the new payload/cell for data transmission. Or, the Node B compares the amount of signal data reported by the terminal UE with the decision threshold, and determines whether to join the new carrier/cell for data transmission.

Step S804: After determining that the new carrier/cell is added for transmission, the Node B notifies the terminal UE through the MAC Control PDU or the physical layer signaling, and the new bearer/cell is enabled.

(1) wherein the MAC Control PDU format is as described in Method A in the deactivation process of Embodiment 3, the ACK received through the HARQ process can be considered that the new carrier/cell is activated, and the Node B can be in the new carrier/cell. The scheduling of the data is sent.

(2) Physical layer signaling: For the downlink 3⁄47 cell enable: When the control channel of HSDPA (High Speed Downlink Packet Access) is sent centrally on one carrier frequency, because one HS-SCCH The format may indicate the data transmission format of two carriers/cells, and the activation of the new downlink carrier/cell may be completed directly in the data format in which the transmission of the newly added carrier/cell is indicated. This indication method does not require an acknowledgement response. The use of the HS-SCCH order to instruct the terminal UE carrier frequency to monitor another carrier frequency can also complete the activation of the new downlink carrier frequency. After receiving the indication, the terminal UE listens to the activated carrier frequency while receiving data on the original carrier frequency. The HS-SCCH channel obtains the HS-DPSCH transmission format to start receiving data on the new carrier frequency. This method can have a special CQI value such as the HS-DPCCH transmission. For uplink carrier/cell activation: HS-SCCH order can be used to activate or use E-AGCH, E-RGCH (E-DCH Relatively Grant Channel, E-DCH Relative Grant Channel) To implement activation, the physical layer signaling may also be signaling carried on the physical layer information enhanced dedicated channel absolute grant channel E-AGCH, or signaling carried on the enhanced dedicated channel relative grant channel E-RGCH.

On the other hand, the UE may also decide whether to activate an uplink carrier, the UE obtains the signal quality by using the measurement of the downlink carrier frequency, and the UE itself knows the transmission amount of the byte, and the UE may be allowed under the premise that the RNC tells the decision criterion. A decision is made and then the network is requested to activate the unused payload/cell. The network determines whether to receive the UE's request based on its own load, signal quality feedback, and the amount of data of the UE. If the request is accepted, scheduling can begin on the activated carrier frequency; if the request is not accepted, a negative response is answered on the original carrier frequency.

On the other hand, the terminal UE may also decide whether to activate/deactivate an uplink carrier/cell, and the terminal UE may cause the terminal UE to make a decision according to the traffic volume of the uplink carrier frequency and the channel quality, on the premise that the RNC tells the decision criterion. And then requesting to activate/deactivate the uplink carrier/cell to the network, where the request may include uplink physical layer signaling or uplink RNC signaling, and the UTRAN network determines whether to accept the terminal according to its own load or downlink signal quality feedback. The request of the UE initiates an activation/deactivation command if the UTRAN network is accepted.

It should be further pointed out that for the deactivation activation judgment of the carrier frequency with the paired physical channels mentioned in the second embodiment, 2d/2c (replace the main carrier frequency) can be used (the IX event can also be used (the main carrier frequency is not replaced). The event can also use the NB's wireless link and out-of-synchronization monitoring function to achieve carrier frequency/cell hold and deactivation. However, the de-lived judgment has a great influence on the terminal UE using multi-carrier transceiving data, so a radio link with a pair of physical channels is usually established in a new carrier/cell before deactivating the current carrier/cell. . At this time, the terminal UE may actually use at least three radio links, one is only the downlink physical channel (non-carrier frequency), and the other is the original radio link with the paired physical channel (cell 1 of the main carrier frequency) The third is a new radio link with a pair of physical channels (cell 2 of the primary carrier frequency). When this happens, the data sent by the wireless links of the new and old paired physical channels are the same. If the frequency of the two wireless links is the same, the process of Figure 9 can be used to implement fast new and old link replacement. process. Specific steps are as follows: Step S901: The terminal UE reports the measurement report IX event, and the RNC decides to add the target cell to the active set of the primary carrier frequency, and notifies the terminal UE by updating the active set, and the RNC and the Node B implement the Iub wireless link reconfiguration process. Node B establishes a wireless link in the new cell.

Step S902: After receiving the active set update, the terminal UE starts monitoring the quality of the pilot channel of the target cell while monitoring the original cell, and reports the CQI to the Node B.

Step S903: After the Node B finds that the target cell CQI is better than the original cell for a period of time, the Node B sends the HS-SCCH at the target to instruct the terminal UE to receive data from the target cell.

Step S904: After receiving the HS-SCCH of the target cell, the terminal UE starts to receive data in the target cell, and does not continue to receive data of the original cell.

Step S905: After receiving the acknowledgement ACK of the received data sent by the terminal UE, the Node B can consider that the terminal UE has switched to the target cell, and therefore can notify the RNC terminal UE of the primary carrier frequency HSDPA serving cell replacement. The notification process can be implemented by adding a cell ID to the signaling using the existing radio link recovery procedure on the Iub.

The function of the HS-SCCH of this embodiment can also be implemented by E-RGCH.

The technical solution of the embodiment of the invention flexibly activates a certain carrier frequency, improves the system capacity, and better performs the effect of load balancing.

Embodiment 5

In the fifth embodiment of the present invention, for some handover area scenarios or two frequency points, there is a large signal fading condition, and the carrier frequency operation method is as follows:

First, the terminal UE also performs measurement at a frequency point other than the available carrier frequency and a cell other than the specified cells (a cell outside the use set), and reports these measurement results to the RNC. Embodiments of the present invention do not change measurement rules other than the set of use, as well as measurement control and measurement reporting rules.

The cells using the set should belong to the same Node B, so the reporting of the signal measurements using the set cells to the RNC can be reduced or cancelled. Node B notifies the RNC when needed.

When the switching area is used, the signal quality of all the frequency points in the centralized set is very poor, and when the deactivation condition is met, the Node B needs to notify the RNC, and the RNC decides to Whether to keep one of the frequencies is still deleted.

The technical solution of the foregoing embodiment of the present invention achieves the flexible activation and deactivation of a carrier frequency by using the Node B as a control center by using the carrier frequency quality information reporting and the threshold determination method. Improve system capacity and better load balancing.

Example eight As shown in FIG. 12, the decision of deactivation or activation of the Node B is described in detail through Embodiment 8 of the present invention. The decision condition of this embodiment is to notify the Node B by sending a carrier frequency deactivation, an activation condition, and a carrier frequency condition to the Node B through the RNC. In this embodiment, the A and B cells are mutually multi-carrier cells.

In this embodiment, based on the carrier frequency measurement performance or the buffer performance or the CQI information of the carrier frequency reported by the terminal UE, it is determined whether the carrier frequency is deactivated. This embodiment includes the following sub-embodiments: Embodiment (1), the Node B judges based on the power load occupied by the carrier frequency HSDPA service. The Node B carrier frequency decision timing can be either an event trigger or a periodic trigger.

Step 11. Establish a multi-carrier/cell connection between the terminal UE and the network.

Step 12: The RNC sends the carrier frequency deactivation, activation condition, and carrier frequency reporting condition to the Node B.

Step 13. Node B feeds back the response information to the RNC.

Step 14: A, B, and the B-cell are in the dual-carrier common working mode. In a time period, in this embodiment, the Node B measures the HSDPA service power of the carrier frequency transmitted by the cell, and the HSDPA service power of the carrier frequency is The power generated by the HSDPA service carrying the carrier frequency. If the power load of the HSDPA service of the carrier frequency of the B cell is higher than the power load pre-configured power threshold, the Order command of a deactivated B cell is triggered to close the reception of the secondary carrier. , to live B community.

Step 15: After the B cell is deactivated, the A cell is in the single carrier carrier frequency working mode. If in a time period, in this embodiment, it is a time observation window, if the HSDPA of the carrier frequency of the B cell occupies the service power load. Below the pre-configured power threshold of the power load, an Order command that activates the B cell is triggered to open the reception of the secondary carrier, and the B cell is activated.

In the embodiment (2), the Node B measures the BER (Bite Error Rate) of the carrier frequency of the DPCCH received by the cell, and the Node B determines the average error rate of the BER based on the carrier frequency. The carrier frequency decision timing can be either an event trigger or a periodic trigger.

Step 21: Establish a multi-carrier/cell connection between the terminal UE and the network.

Step 22: The RNC sends a carrier frequency deactivation, an activation condition, and a carrier frequency reporting condition to the Node B. Step 23: The Node B feeds back the response information to the RNC.

Step 24: A, B cell is in a dual carrier carrier frequency working mode, and in one time period, in this embodiment, it is a time observation window, if the average error rate of the BER of the carrier frequency of the B cell is higher than that at this stage. The pre-configured threshold of the average bit error rate will trigger an Order command to deactivate the B-cell.

Step 25: After the B cell is deactivated, the A cell is in the single carrier carrier frequency working mode. According to the timer set by the upper layer, after the timer expires, an Order command of the activated B cell is triggered to activate the B cell. After the B cell is deactivated, the Node B cannot measure the BER of the B cell DPCCH, so it needs to be activated by using the timer.

In the embodiment (3), the Node B is determined based on the CQI report, and the method is described in the first embodiment, and details are not described herein again.

In the embodiment (4), the number of bytes of the HSDPA service to be transmitted of the carrier frequency is measured on the Node B side, and the HSDPA pending traffic of the carrier frequency is stored in the buffer BUFFER of the Node B. In the multi-carrier/cell, the carrier frequency in the affiliation with respect to the primary carrier frequency is the secondary carrier frequency, and in the embodiment is the B-cell.

The Node B determines based on the number of bytes to be sent by the current HSDPA service. The carrier frequency decision timing can be either an event trigger or a periodic trigger.

Step 31: Establish a multi-carrier/cell connection between the terminal UE and the network.

Step 32: The RNC sends the carrier frequency deactivation, activation condition, and carrier frequency reporting condition to the Node B.

Step 33: The Node B feeds back the response information to the RNC.

Steps 34, A, and B are in a dual carrier carrier frequency working mode. In a time period, in this embodiment, in a time observation window, if the current cell UE of the B cell is in a multi-carrier/cell HSDPA service pending word If the value of the node is lower than the pre-configured threshold, an Order command to deactivate the B-cell will be triggered to turn off the acceptance of the secondary carrier frequency to deactivate the B-cell. The B cell belongs to the secondary carrier frequency in the current multi-carrier/cell.

Step 35: After the B cell is deactivated, the A cell is in the single carrier carrier frequency working mode, and the value of the HSDPA service to be sent in the multi-carrier/cell of the current terminal UE of the B cell is in a time period, in this embodiment, Within a time observation window, above the pre-configured threshold, Then, an Order command that activates the B cell is triggered to open the reception of the secondary carrier frequency, and the B cell is activated.

Embodiment (5) determines the Node B based on the ACK and NACK ratio of the carrier frequency of the cell. The carrier frequency decision timing can be either an event trigger or a periodic trigger.

After performing the check or receiving the information, the terminal UE sends a reply message to the Node B. If the reply message received by the Node B is an ACK, it indicates that the check result or the received information is correct; if the Node B receives the reply message If it is NACK, it indicates that the verification result or the received information is wrong.

Step 51: Establish a multi-carrier/cell connection between the terminal UE and the network.

Step 52: The RNC sends the carrier frequency deactivation, activation condition, and carrier frequency reporting condition to the Node B.

Step 53: The Node B feeds back the response information to the RNC.

The ACK and NACK ratios of the carrier frequency of the B cell are lower than the pre-configured threshold in a time observation window in this embodiment. Then, the Order command that triggers a deactivated B cell turns off the acceptance of the secondary carrier carrier frequency, and deactivates the B cell.

Step 55: The A cell is in the single carrier carrier frequency mode. After the timer configured on the Node B is timed out, an Order command that activates the B cell is triggered to enable the reception of the secondary carrier carrier frequency, and the B cell is activated. After the B cell is deactivated, the Node B cannot receive the ACK and NACK messages of the B cell's carrier frequency, so it needs to be activated by the timer.

In this embodiment, the NodeB decides to deactivate a carrier, for example, after the carrier/cell B is deactivated, if the carrier/cell B is a downlink carrier/cell, the NodeB will prepare the data to be transmitted by the carrier/cell B. Both return to the carrier/cell A for transmission. For the data packet that has been sent but has not received the HARQ response from the terminal UE, it waits for the HARQ response of the terminal UE. If the response time has not exceeded, the response of the terminal UE is not received or If the response is NACK, the retransmission is not carried on the cell/cell B, but the data is transferred to the carrier/cell A for retransmission. The data for retransmission should be sent preferentially on carrier/cell A. For those packets sent from carrier/cell B to carrier/cell A, the packets are sorted according to the sequence number of the RLC layer of the data, instead of directly loading them. The tail of the data sequence in cell A. 5 is a data transmission state of two carriers/cells in which the carrier/cell B is deactivated, and FIG. 7 is a case where the data in the queue corresponding to the carrier/cell B is transferred to the carrier/cell A after the carrier/cell B is deactivated. A schematic to send. If two carriers/cells share a single MAC-hs/ehs queue, only the data to be retransmitted needs to be processed, and the queue transfer and insertion process is omitted.

The command terminal deactivates the secondary carrier frequency. In this embodiment, the secondary carrier frequency is the B cell, and then the data operation process of the secondary carrier frequency deactivated by the terminal is specifically:

The data whose secondary carrier frequency has been sent but has not received a response waits for a response;

The data that the secondary carrier frequency has been sent but has not received the response or received the failure response within the response time is retransmitted by other carrier frequencies;

The data that is not sent by the secondary carrier frequency is transferred to the transmission sequence of other carrier frequencies according to the serial number of the data to transmit or discard the data.

When the new carrier frequency quality is stronger than the quality of the existing carrier frequency, replace the existing carrier frequency with a new carrier frequency, or use a new secondary carrier frequency when the new carrier frequency quality is stronger than the quality of the existing carrier frequency. Replace the existing carrier frequency.

Embodiment IX,

As shown in Fig. 13, the deactivation or activation of the RNC will be described in detail by the ninth embodiment of the present invention. The RNC decision timing can be either an event trigger or a periodic trigger. The RNC determines whether to deactivate the B cell by determining the downlink error rate of the carrier frequency.

Step 1: Establish a multi-carrier/cell connection between the terminal UE and the network;

Step 2: The RNC forwards the carrier frequency reporting condition to the terminal UE via the Node Node B. Step 3: The terminal UE forwards the response information to the RNC via the Node B. Step 4: A, B cells are multi-carrier cells, A, B The cell is in the dual carrier frequency mode, and the terminal UE is in a time period. In this embodiment, it is a time observation window. If the downlink error rate of the carrier frequency of the B cell is higher than the pre-configured threshold of the downlink error rate, the terminal UE reports The event informs the RNC that the RNC, through the Node B, triggers an Order command to deactivate the B-cell to close the acceptance of the secondary carrier frequency and deactivate the B-cell. The terminal UE can also report the cell periodically. Bit error rate.

Step 5: After the B cell is deactivated, the A cell is in the single carrier frequency working mode. According to the timer set by the upper layer, the RNC starts a timer. After the timer expires, the RNC triggers an Order command of the activated B cell through the Node B. . After the B cell is deactivated, the terminal UE cannot report the bit error rate of the B cell, so it is necessary to use timer timer activation.

Example ten

As shown in Figure 14, after the RNC determines, the dual carrier carrier frequency cell activates the deactivation signaling procedure.

In this embodiment, the A and B cells are mutually multi-carrier cells.

Step S1401: The RNC sends a control message to the terminal UE to trigger an activation deactivation decision. The control message includes a channel quality threshold, a terminal UE service threshold, a decision condition, a reporting period, and the like, and can control the terminal UE to report in an event or a periodic manner.

Step S1402: The terminal UE reports the channel quality measurement result and the terminal UE service measurement result, and the RNC performs the judgment activation/deactivation.

Step S1403: If the reported signal quality is less than the threshold, the judgment result is deactivated, and the RNC sends a control to deactivate the B-cell message to the Node B, where the message may include the following: cell identifier, terminal UE identifier, activation/deactivation Activity

Step S1404: The Node B forwards the deactivated B cell Order command to the terminal UE. Step S1405: The terminal UE works in a single carrier A cell.

Step S1406: The terminal UE reports the result, and the RNC performs the judgment.

Step S1407: If the reported signal quality is smaller than the threshold, the decision is activated.

The RNC sends a control activated B cell message to the Node B, and the message may include the following cells: a cell identifier, a terminal UE identifier, and an activation/deactivation activity;

Step S1408: The Node B forwards the Activate B cell Order command to the terminal UE. Step S1409: The terminal UE works in the multi-carrier cell A and the B cell.

The technical solution of the embodiment of the present invention flexibly activates and deactivates a certain carrier frequency through the process controlled by the Node B, thereby improving system capacity and better performing load balancing. Embodiment 11

As shown in FIG. 15, in the embodiment of the present invention, the Node B determines the signaling flow of the activation deactivation state to the RNC after the activation is deactivated. A, B cells are mutually multi-carrier cells.

S1501: The Node B decides to activate or deactivate the B carrier cell operation for the terminal UE;

S1502: The Node B sends an activated or deactivated B carrier cell command to the terminal UE. S1503: The terminal UE feeds back to the Node B to activate or deactivate the B carrier cell to successfully respond;

51504, the Node B is activated or deactivated, and the B carrier cell successfully responds, and feeds back to the RNC a B carrier cell activation or deactivation status indication message, where the message needs to include the activated/deactivated terminal UE identifier. The identifier may be U-RNTI, H-RNTI, E-RNTI, CRNC CONTEXT, Node B CONTEXT, but is not limited to the above identification type.

After receiving the message, the RNC will set the working mode variable of the terminal UE to DUAL CELL dual carrier frequency or SINGLE CELL single carrier frequency. If the status indication message is the activated B carrier cell, the working mode of the terminal UE is changed to the DUAL CELL dual carrier frequency, and the information of the activated B carrier cell is saved; if the status indication message is the deactivated B carrier cell, the working mode of the terminal UE Switch to SINGLE CELL single carrier frequency, you need to delete the B carrier cell information.

The method of this embodiment may further include:

51505. The RNC sends an activation/deactivation status indication response message to the Node B.

The technical solution of the embodiment of the present invention can flexibly activate and deactivate a carrier frequency through the RNC control process, improve system capacity, and better perform load balancing effects.
