Description

A carrier frequency control method and device in a multi-carrier/cell system

technical field

The present invention relates to the field of communication technology, in particular to a carrier frequency control method and device in a multi-carrier/cell system. the

Background technique

The existing HSPA (High-Speed Packet Access) system is carried on a single frequency point. In order to further increase the data transmission rate of the HSPA system, reduce the delay and improve user experience, a method of combining multiple A scheme of bundling frequency points for carrying HSPA data is proposed. In this solution, two (or more) 5MHz carrier frequencies in the downlink direction will be bundled together for transmission of HSPA data. The most important of these is the case of bundling two carrier frequencies. These two carrier frequencies can be regarded as the frequency points used by two cells covering the same area, and the number of carrier frequencies used for uplink and downlink They can be the same or different, but generally the number of downlink carrier frequencies is more than the number of uplink carrier frequencies. This system of bundling multiple carrier frequencies for HSPA data transmission generally uses: 2 carrier frequencies for downlink and 2 carrier frequencies for uplink, called 2*2 mode; or 2 carrier frequencies It is used for downlink, and one carrier frequency is used for uplink, which is called 2*1 mode, and no matter which mode involves the problem of using two carrier frequencies for downlink. the

A multi-carrier/cell can support multiple carrier frequencies, and the cells corresponding to these carrier frequencies generally have a certain correlation in geographical location. There are two ways to define multi-carrier/cell. One refers to a special cell different from the original single carrier/cell. This cell has its own cell ID and supports multiple carrier frequencies; the other refers to a set of cells. Concept, each cell in the set is an independent individual like the original single carrier/cell, and their cell IDs can be the same or different. the

Introduce the concept of main carrier frequency. If only one carrier frequency is used for uplink or downlink, then use this frequency point as the main carrier frequency. If the uplink and downlink services are carried on the DCH (Dedicated Channel, Dedicated Channel), the frequency point where the DCH is located is used as the main carrier frequency. If both uplink and downlink use two carrier frequencies at the same time and no traffic is carried on the DCH, then the RNC (Radio Network Controller, radio network controller) reports the 2a event (preferably the carrier frequency change) according to the UE (User Equipment, user equipment) ) determines the change of the primary carrier frequency, and each time the primary carrier frequency is changed, the RNC sends a new measurement control message to inform the UE of the frequency point used for intra-frequency handover measurement. the

The UE only determines the triggering of 1x/2x events based on the main carrier frequency, but it needs to carry the information of the two frequency points when reporting the measurement report. The network side needs to consider comprehensively when deciding whether to add the cell to the active set (especially when the 1d event is triggered) The signal quality of the two carrier frequencies. the

In the above description, inter-frequency events such as 2x events are used for measurement events of non-primary carrier frequencies/cells, and 1x events are used for measurement events of carrier frequencies/cells of carrier frequencies. For example: the main carrier frequency corresponds to carrier frequency A, cells 1 and 2; the non-main carrier frequency corresponds to carrier frequency B, cells 3 and 4. Then use 2a, 2b, 2c, 2d for the measurement events of cells 3 and 4. For cells 1 and 2 use 1a, 1b, 1c, 1d events. the

Applying the above method can use multiple carriers/cells for data transmission, but because the environment where the user terminal is located may change at any time, and correspondingly, the quality of the carrier frequency may also change accordingly, but the existing technical solutions do not provide the ability to transmit data according to the carrier frequency. The method of adjusting the carrier frequency due to the change of the frequency quality affects the optimization of the network quality. the

Detailed ways

Embodiments of the present invention provide a carrier frequency control method and device in a multi-carrier/cell system, which realizes corresponding deactivation or activation operations on carrier frequencies through carrier frequency quality reporting and threshold judgment in a multi-carrier/cell system, thereby Optimize network quality and improve user experience. the

Below in conjunction with accompanying drawing and embodiment, the specific embodiment of the present invention is described in further detail:

As shown in Figure 1, it is a schematic flow diagram of a carrier frequency control method in a multi-carrier/cell system in Embodiment 1 of the present invention, including the following steps:

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

Establish multi-carrier/cell connections through two downlink carrier frequencies and one or two uplink carrier frequencies. the

When the above-mentioned multi-carrier/cell connection is established through two downlink carrier frequencies and one uplink carrier frequency, an F-DPCH (Fractional Dedicated Physical Channel) is established on the downlink carrier frequency corresponding to the uplink carrier frequency for uplink Power control of the physical channel, and data transmission through HS-DSCH (High-Speed Down Share Channel, high-speed downlink shared channel); data transmission is performed through HS-DSCH on the remaining downlink carrier frequencies. the

For the detailed description of this step and the additional fields that need to be written in each signaling, refer to the second embodiment of the present invention. the

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

Specifically, the deactivation threshold, activation threshold and carrier frequency reporting conditions,

Step S103, the RNC forwards the carrier frequency report condition to the terminal UE via the Node B. the

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

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

It should be pointed out that the sequence between steps S103 and S104 can be exchanged, and the change of the sequence will not affect the protection scope of the present invention. the

Step S105, the terminal UE forwards the response information to the RNC via the Node B. the

Step S106, the terminal UE reports the CQI (Channel Quality Indicator, channel quality indicator) information of the carrier frequencies A and B that meet the carrier frequency reporting conditions to the Node B. the

The reporting method includes: carrying CQI information through MAC (Media Access Control, media control layer) PDU (Protocol Data Unit, protocol data unit) for reporting; or, carrying CQI information for reporting through physical layer signaling. the

Step S107, Node B compares the CQI information with the deactivation threshold, judges that the quality of the carrier frequency B is lower than the deactivation threshold, and decides to deactivate the carrier frequency B. the

Step S108, the Node B sends an instruction to deactivate the carrier frequency B to the terminal UE, and the carrier frequency B is deactivated. the

The method for sending the above instruction includes: using the deactivation instruction carried by the MAC control PDU, or the deactivation instruction carried by the physical layer signaling. the

Step S109, the terminal UE sends the feedback of deactivating the carrier frequency B to the Node B. the

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

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

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

Step S111, Node B compares the CQI information with the activation threshold, judges that the quality of the carrier frequency B is higher than the activation threshold, and decides to activate the carrier frequency B. the

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

Activate the carrier frequency B through the activation command carried by the MAC control PDU; or,

Activate the carrier frequency B through the activation command carried in the physical layer signaling

Step S113, the terminal UE sends the feedback of activating the carrier frequency B to the Node B. the

It should be further explained that when step S102 of this embodiment only sends the deactivation threshold and carrier frequency reporting conditions, steps S101 to S109 constitute the carrier frequency deactivation process; when step S102 of this embodiment only sends the activation threshold and carrier frequency When reporting conditions, steps S101 to S105 and S110 to S113 constitute a carrier frequency activation process. Such changes also belong to the protection scope of the present invention. the

The technical solution of the embodiment of the present invention has the following advantages. The base station Node B is used as the control center to flexibly activate and deactivate a certain carrier frequency, improve the system capacity, and achieve better load balancing effects. the

Example two

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

A cell with multi-carrier/cell capability will broadcast its own multi-carrier/cell capability or the coordination capability between multi-carrier/cells. For example, Node B is configured with 3 frequency points, and each frequency point has 2 cells. These cells are different Cells with different carrier frequencies can cooperate. A terminal UE with multi-carrier/cell capability will report its own capability in an RRC (Radio Resource control, radio resource control) connection establishment request (in this embodiment, take the RRC connection setup request message as an example), and the network UTRAN receives the terminal UE In the RRC connection setup request message of the terminal UE, at the same time, it 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 multi-carrier/cell reception in the RRC connection setup (RRC connection setup complete) message. capability and or multi-carrier/cell transmission capability. the

When the terminal UE is already in the connected state and 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 multi-carrier/cell through various reconfiguration messages. Cell receive capability and or multi-carrier/cell transmit capability. UTRAN can configure a corresponding UEID for each carrier/cell usage. For example: the terminal UE can use 2 downlink carriers/cells and one uplink carrier/cell, then the terminal UE should have 2 H-RNTI (HS-DSCH Radio Network Identifier), 1 Primary E -RNTI (Primary Enhanced Radio Network Identifier, 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

The network establishes a multi-carrier/cell connection with the terminal through multiple downlink carrier frequencies and multiple uplink carrier frequencies. The number of downlink carrier frequencies is greater than or equal to the number of uplink carrier frequencies. frequency and N uplink carrier frequencies are established, and when M is greater than N, F-DPCH (partial dedicated physical channel) is established on the N downlink carrier frequencies corresponding to the uplink carrier frequency to control the power of the uplink physical channel, and through the HS-DSCH (High-speed downlink shared channel) for data transmission, and data transmission on the remaining M-N downlink carrier frequencies through HS-DSCH. For example: if only one uplink carrier/cell is used by the terminal UE, data transmission is performed through HS-DSCH on two downlink frequency points. And you can only establish F-DPCH on the corresponding downlink frequency point to control the power of the uplink physical channel. Since there is no corresponding uplink physical channel on the other downlink frequency point, there is only HS-DSCH without establishing power control for the uplink. downlink physical channel. the

Establishing a multi-carrier/cell connection between the terminal UE and the network includes the following steps:

Step s201, the network receives the multi-carrier/cell capability information sent by the terminal. the

More specifically, after receiving the capability information of the terminal, the network sends feedback information to the terminal. the

Step s202, the network establishes a multi-carrier/cell connection. the

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

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

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

Table 1-5 specifically lists the information elements in the message that instruct the terminal UE to use multi-carrier/cell receiving capability and/or multi-carrier/cell transmitting capability. The following table is just a specific demonstration. Based on the technical idea of the present invention, the following table The modifications made do not affect the scope of protection of the embodiments of the present invention. the

Embodiment three

As shown in Figure 3, through Embodiment 3 of the present invention, the process of judging the deactivated carrier frequency is described in detail, including the following steps:

Step S301, the terminal UE receives a carrier frequency report condition. the

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

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

In this step, the method for reporting the measurement value of the deactivated carrier/cell of the terminal UE to the NodeB and which own measurements the NodeB can obtain information such as the quality and power of the wireless link of a certain carrier/cell should be specified. At present, the terminal UE reports the CQI in the HS-DPCCH (High-Speed Dedicated Physical Control Channel, high-speed dedicated physical control channel), and this value can be used as the input quantity for the NodeB to make a decision. The NodeB receiver can use the received BLER value to report to the NodeB scheduler for the NodeB to make a decision. the

Step S303, Node B compares the CQI information with the deactivation threshold, and judges whether to deactivate the carrier frequency. the

The deactivation threshold in this step is sent to Node B by RNC. the

The deactivation threshold includes the following: the signal quality of the carrier/cell is lower than a threshold (Ec/N0); and or the signal power (RSCP) of the carrier/cell is lower than a threshold; and or the data transmitted on this carrier/cell and or the power of data transmission on this carrier/cell is higher than a threshold; and or the number of retransmissions of data on this carrier/cell is higher than a threshold; and or NodeB Synchronization of a link with the terminal UE is lost. The duration of the above conditions may be a certain period of time before a decision can be made, or a decision can be made immediately, which depends on the purpose and requirements of the UTRAN for each carrier/cell. This condition is notified by the RNC to the NodeB, and the terminal UE does not have to know it. The method for the RNC to notify the NodeB is to add a special signaling on the Iub interface, or to carry it in the message of wireless link establishment and reconfiguration. the

S304. The Node B sends an instruction to deactivate the carrier frequency to the UE to deactivate the carrier frequency. The steps for deactivating the carrier frequency are further described below, including the following steps:

Step 1, Node B decides to deactivate a certain 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, it notifies the terminal UE to deactivate a certain carrier/cell. Specifically include the following two methods:

Method A, as shown in FIG. 4 and FIG. 5 , notifies the terminal UE through the fields of the MAC control PDU. The fields contained in the MAC control PDU are specifically described as follows:

C/T is the PDU indication 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 contains the carrier frequency control item;

The signal quality item is used to indicate whether the PDU contains a signal quality CQI reporting 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;

The carrier frequency activation bit is used to indicate the activation/deactivation of the carrier/cell, and each carrier frequency occupies 1 bit; 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 bits, including the signal quality of all carrier frequencies;

Status response content bit, for activation/deactivation response, each carrier frequency occupies 1 bit. When the carrier frequency is activated/deactivated, a positive response ACK (ACKnowledge Character, confirmation character) is replied, and when the carrier frequency is not activated/deactivated, a negative response NACK (None ACKnowledge Character, deny character) is replied. the

One item of the control PDU is defined as whether to use a certain downlink carrier/cell, and the other item is defined as whether to use a certain uplink carrier/cell. These two items can each occupy a 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 controlling whether the carrier/cell is deactivated is equal to the number of uplink and downlink carriers/cells, or is equal to the number of the most used downlink carriers/cells. The order of these bits is the same as the list order of the carriers/cells when the terminal UE receives the connection establishment or reconfiguration message. the

After Node B decides to deactivate a carrier/cell, it should send this MAC control PDU to the terminal UE, and preferentially use the downlink carrier/cell that is not deactivated to send this MAC PDU, so as to ensure that the control information is received reliably. After the terminal UE receives the deactivation notification, it should respond to Node B to indicate that it has received the notification information. The response message can be HARQ (Hybrid Automatic Repeat reQuest, Hybrid Automatic Repeat Quest) ACK, or it can be the control PDU of the MAC layer answer. As shown in FIG. 5 , it is a schematic diagram of the content of the status response item. This response should be sent with priority to the uplink carrier/cell that is not disabled. the

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

NodeB decides to deactivate a carrier/cell, for example, after carrier/cell B is deactivated, if this carrier/cell B is a downlink carrier/cell, NodeB will have prepared to let the data sent by carrier/cell B return to carrier/cell A Up and send, for data packets that have been sent but have not received the HARQ response of the terminal UE, wait for the HARQ response of the terminal UE, if the response time has passed and the response of the terminal UE has not been received or the response is NACK, then no longer instead of retransmitting on carrier/cell B, the data is transferred to carrier/cell A for retransmission. The retransmitted data should be sent preferentially on the carrier/cell A. For those data packets that are transferred from carrier/cell B to carrier/cell A, they are sent according to the sequence number of the RLC layer of the data, instead of putting them directly at the end of the data sequence in carrier/cell A. Figure 5 shows the data transmission status of the two carriers/cells when the carrier/cell B is deactivated, and Figure 7 shows the data in the queue corresponding to the carrier/cell B being transferred to the carrier/cell A after the carrier/cell B is deactivated Schematic diagram sent. If two carriers/cells share one MAC--hs/ehs queue, only the retransmitted data needs to be processed, and the transfer and insertion process of the queue is omitted. the

When the NodeB decides to deactivate an uplink carrier/cell, for example, to deactivate the carrier/cell C, the NodeB should pass the received but unanswered data packets through the E-HICH (E-DCH HARQ Acknowledgment Indicator Channel, E-DCH HARQ Acknowledgment Indication Channel) gives a response to the terminal UE, and the NodeB will finish receiving the data of the terminal UE that has been scheduled before the deactivation notification. Then stop scheduling this carrier/cell C. the

After the terminal UE receives the MAC control PDU, it analyzes and finds that it is notifying the terminal UE to stop using a certain carrier/cell, and the terminal UE will process the data on this carrier/cell as follows:

1) When the deactivated carrier/cell is a downlink carrier/cell, the terminal UE will perform CRC (Cyclical Redundancy Check) on the data packet (not this MAC PDU) received by the deactivated carrier/cell Verification) verification, if the verification result is correct, it will respond to NodeB ACK, and if the verification is wrong, it will respond to NACK. If there is no data packet to be received at this time, the receiving of the carrier/cell is directly stopped and the timer and counter related to the carrier/cell are deleted. the

2) When the deactivated carrier/cell is an uplink carrier/cell, the terminal UE should first use up the resources that must have been scheduled on this carrier/cell, and then stop the data transmission of this carrier/cell. And transfer the data originally intended to be sent on the deactivated carrier/cell to another carrier/cell for sending. For the data that needs to be retransmitted on the deactivated carrier/cell, the terminal UE needs to send it preferentially on another carrier/cell; for the transferred data, it needs to be inserted into another carrier/cell for transmission according to the data sequence of the radio link control protocol. Insert directly at the end of the queue. the

On the other hand, if the deactivation condition of the main carrier frequency cell is met, and the cell is deactivated when the serving cell in the main carrier frequency, the Node B shall notify the RNC that it cannot be deactivated immediately and must wait for the decision of the RNC. The RNC's decision includes: deactivation means that the terminal UE no longer maintains any wireless link; rejoining a new cell in the main carrier frequency, the terminal UE establishes a connection with the new cell for data transmission, and the newly added cell is the serving cell . Replace the auxiliary carrier frequency with the main carrier frequency. the

It should be further pointed out that, for the carrier frequency that only transmits data in Embodiment 2 of the present invention, because it does not have a corresponding uplink physical channel and F-DPCH for inner-loop power control, the NodeB cannot monitor the uplink frequency of the existing technology. Link out of synchronization to inform RNC that the wireless link corresponding to this carrier frequency is available or invalid to realize the removal or link maintenance of the wireless link, so the activation of this single downlink frequency point is reported by the measurement of the terminal UE (2d/2c event) is a better way. That is, when the 2c event is satisfied, continue to maintain the wireless connection of the carrier frequency, and delete the connection when the 2d event occurs. the

In addition to the method proposed in this embodiment, the control right to deactivate the carrier/cell can also be placed on the RNC, but since the information of the RNC or the terminal UE passes through the Node B and the Iub interface between the two , this process introduces a considerable delay (200ms). Moreover, Node B can actually directly obtain the signal quality and transmission quality of the wireless link of each carrier/cell through the CQI reporting of HS-DPCCH and the reception of uplink data, so the deactivation control of the carrier/cell is delegated It is feasible to reach the Node B and the transmission time of the Iub interface is subtracted. This kind of control is more flexible and can be realized by using physical layer signaling or MAC layer signaling. the

Method B, using physical layer signaling

HS-SCCH order (High-Speed Shared Control Channel order, High-Speed Shared Control Channel signaling) can be used to instruct a downlink or uplink carrier/cell to stop using. the

E-AGCH (E-DCH Absolute Grant Channel, Enhanced Dedicated Channel Absolute Grant Channel) can be used to carry Primary E-RNTI, and all activation bits are set to inactive to indicate deactivation of the uplink carrier/cell. the

Because there is no corresponding response mechanism for these two types of physical layer signaling, in order to ensure reliability, Node B can send several times continuously when sending. the

After the deactivation instruction is issued, the sending process of the data packets on the originally deactivated carrier/cell of the Node B and the terminal UE is the same as that described in method A. the

The technical solutions of the embodiments of the present invention flexibly deactivate a certain carrier frequency, improve system capacity, and achieve better load balancing effects. the

Embodiment four

As shown in FIG. 8 , the process of activating the carrier frequency is described in detail through Embodiment 4 of the present invention. the

When the terminal UE is performing data transmission in multiple carriers/cells, the terminal UE will always monitor the signal quality of the carrier/cell it can use, and then report the signal quality. When the terminal UE or Node B finds an unused When the quality of the carrier/cell becomes better and it becomes possible to use it to transmit data, the unused carrier/cell can be added to the transmission carrier/cell set. When the quality of the new carrier frequency is stronger than that of the existing carrier frequency, the new carrier frequency is used to replace the existing carrier frequency. Step S102 to step S105 and step S110 to step S113 are shown in FIG. 1 . Specific steps are as follows:

Step S801, the RNC will simultaneously notify the Node B and the terminal UE to measure the signal quality of unused carriers/cells, the measurement strategy and the reporting strategy of the measurement results. The RNC notifies the Node B to enable the quality threshold and data volume threshold for carrier/cell transmission. the

Step S802, the terminal UE will report the signal quality and data volume of the pilot of the unused frequency point, the reporting method is: MAC control PDU, the specific format is shown in Figure 4. the

Step S803, Node B compares the signal quality reported by the terminal UE with the judgment threshold value, and makes a judgment whether to add a new carrier/cell for data transmission. Or, the Node B compares the amount of signal data reported by the terminal UE with the decision threshold, and makes a decision whether to add a new carrier/cell for data transmission. the

Step S804, after the Node B decides to add a new carrier/cell for transmission, it notifies the terminal UE through MAC control PDU or physical layer signaling that the new carrier/cell is enabled. the

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

(2) Physical layer signaling: For the enablement of downlink carrier/cell: when the control channel of HSDPA (High Speed Downlink Packet Access, high-speed downlink packet access technology) is sent collectively on a carrier frequency, because an HS-SCCH The format can indicate the data transmission format of the two carriers/cells, and the activation of the new downlink carrier/cell can be completed by directly indicating the data format sent by the newly added carrier/cell. This indication method does not require a confirmation response. Using HS-SCCHorder 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 this instruction, the terminal UE will listen to the activated carrier frequency while receiving data on the original carrier frequency. The HS-SCCH channel obtains the transmission format of the HS-DPSCH to start receiving data on a new carrier frequency. This method can have a special CQI value for confirmation such as HS-DPCCH transmission. For the activation of the uplink carrier/cell: HS-SCCH order can be used to activate or E-AGCH, E-RGCH (E-DCHRelatively Grant Channel, E-DCH relative grant channel) can be used to achieve activation. The physical layer signaling can also be used It is the signaling carried on the enhanced dedicated channel absolute grant channel E-AGCH for physical layer information, or the signaling carried on the enhanced dedicated channel relative grant channel E-RGCH. the

On the other hand, the UE can also decide whether to activate a certain uplink carrier/cell. The UE obtains the signal quality through the measurement of the downlink carrier frequency. The UE knows the amount of bytes to send. On the premise that the RNC tells it the decision criteria, the UE Make a decision and then request the network to activate an unused carrier/cell. The network decides whether to accept the UE's request according to its own load, signal quality feedback, and the data volume of the UE. If the request is accepted, scheduling can be started on the activated carrier frequency; if the request is not accepted, a negative response is answered on the original carrier frequency. the

On the other hand, the terminal UE can also decide whether to activate/deactivate a certain uplink carrier/cell, and the terminal UE can let the terminal UE make a decision based on the traffic volume and channel quality of the uplink carrier frequency and on the premise that the RNC tells it the decision criteria , and then request to the network to activate/deactivate the above-mentioned uplink carrier/cell, the request method may include uplink physical layer signaling or uplink RNC signaling, and the UTRAN network decides whether to accept the terminal according to its own load or downlink signal quality feedback UE's request, if the request is accepted, the UTRAN network will initiate an activation/deactivation command. the

It should be further pointed out that for the deactivation and activation judgment of the carrier frequency with paired physical channels mentioned in the second embodiment, 2d/2c (replacing the main carrier frequency) (1X event is also possible (not changing the main carrier frequency) ) events can also use the NB's wireless link and out-of-sync monitoring function to maintain and deactivate the carrier frequency/cell. However, the determination of deactivation has a relatively large impact on the use of multi-carrier data transmission and reception by the terminal UE, so before deactivating the current carrier frequency/cell, a wireless link with paired physical channels is usually established in a new carrier frequency/cell . At this time, the terminal UE may actually use at least three wireless links, one is only downlink physical channels (non-carrier frequency), and the other is the original wireless link with paired physical channels (main carrier frequency cell 1) , the third one is a new wireless link with paired physical channels (cell 2 of the main carrier frequency). When this happens, the data sent by the wireless links of the old and new paired physical channels is the same. If the frequency points of the two wireless links are the same, the process in Figure 9 can be used to quickly replace the old and new links process. Specific steps are as follows:

Step S901, the terminal UE reports the measurement report 1X event, the RNC decides to add the target cell to the active set of the main carrier frequency, and notifies the terminal UE by "updating the active set", while the RNC and NodeB use the radio link reconfiguration process of Iub to realize Node B establishes a radio link in the new cell. the

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

Step S903, after the Node B finds that the CQI of the target cell is better than that of 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. the

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 in the original cell. the

Step S905, when the Node B receives the data acceptance ACK sent by the terminal UE, it can consider that the terminal UE has switched to the target cell, so it can notify the RNC that the main carrier frequency HSDPA serving cell of the terminal UE is changed. The notification process can be realized by adding a cell ID in the signaling by using the existing wireless link recovery process on the Iub. the

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

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

Embodiment five

Embodiment 5 of the present invention, in view of some handover area scenarios or situations where both frequency points have relatively large signal fading, the carrier frequency operation method is proposed as follows:

Firstly, the terminal UE will also perform measurements at frequency points other than the usable carrier frequency and cells other than the specified cells (cells outside the use set), and report these measurement results to the RNC. The embodiment of the present invention does not change the measurement rules outside the use set, and the measurement control and measurement reporting rules. the

The cells using the set should belong to the same Node B, so the reporting of the signal measurement of the cells using the set to the RNC can be reduced or canceled. When necessary, the Node B can notify the RNC. the

When in the handover area, the signal quality of all the frequency points in the use set is very poor and all meet the deactivation conditions, Node B needs to notify the RNC, and the RNC decides whether to keep one of the frequency points or delete them all . the

Embodiment eight

As shown in FIG. 12 , through the eighth embodiment of the present invention, the decision to deactivate or activate Node B is described in detail. The decision condition in this embodiment is notified to the Node B by the RNC sending the carrier frequency deactivation, activation condition and carrier frequency reporting condition to the Node B. In this embodiment, cells A and B are mutually multi-carrier cells. the

In this embodiment, it is judged whether to deactivate the carrier frequency according to the carrier frequency measurement performance or buffer performance or the CQI information of the carrier frequency reported by the terminal UE. This embodiment includes the following sub-embodiments:

In the 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 may be triggered by an event or periodically. the

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

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

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

Step 14, A, B cells are in dual-carrier co-working mode, within a period of time, in this embodiment is a time observation window, 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 Refers to the power generated by the HSDPA service of the carrier frequency. If the power load of the HSDPA service of the carrier frequency of the B cell is higher than the pre-configured power threshold of the power load, an Order command to deactivate the B cell will be triggered to disable the reception of the secondary carrier. , deactivate cell B. the

Step 15, after the B cell is deactivated, the A cell is in the single-carrier carrier frequency working mode. If within a period of time, in this embodiment, it is a time observation window, if the service power load occupied by the carrier frequency of the B cell is always If it is lower than the pre-configured power threshold of the power load, an Order command to activate the B cell will be triggered to enable the reception of the secondary carrier and activate the B cell. the

In 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 judges based on the average bit error rate of the BER of the carrier frequency. The carrier frequency decision timing can be triggered by events or periodically. the

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

Step 22, RNC sends carrier frequency deactivation, activation condition and carrier frequency reporting condition to Node B. the

Step 23, Node B feeds back response information to RNC. the

Step 24, A, B cell is in the dual-carrier carrier frequency co-working mode, within a period of time, in this embodiment is a time observation window, if the average bit error rate of the BER of the carrier frequency of B cell at this stage is higher than If the pre-configured threshold of the average bit error rate is used, an Order command to deactivate the B cell will be triggered. the

Step 25: After cell B is deactivated, cell A 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 for activating cell B will be triggered to activate cell B. After the B cell is deactivated, the Node B cannot measure the BER of the DPCCH of the B cell, so a timer needs to be used for timing activation. the

Embodiment (3) is that the Node B makes a judgment based on the CQI report. This method has been described in Embodiment 1 and will not be repeated here. the

Embodiment (4), measure the number of bytes to be sent by the HSDPA service of the carrier frequency at the Node B side, and the HSDPA service volume to be sent by the carrier frequency is stored in the cache BUFFER of the Node B. In multiple carriers/cells, relative to the main carrier frequency, the secondary carrier frequency is the secondary carrier frequency, which is the B cell in this embodiment. the

Node B judges based on the number of bytes to be sent in the current HSDPA service. The carrier frequency decision timing may be triggered by an event or periodically. the

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

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

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

Step 34. A and B cells are in the dual-carrier carrier-frequency co-working mode. Within a period of time, in this embodiment, within a time observation window, if the HSDPA service of the multi-carrier/cell of the current terminal UE in B cell is ready to send bytes If the value is lower than the pre-configured threshold, an Order command to deactivate the B cell will be triggered to disable the acceptance of the auxiliary carrier frequency and deactivate the B cell. The B cell belongs to the auxiliary carrier frequency in the current multi-carrier/cell. the

Step 35: After cell B is deactivated, cell A is in the single-carrier carrier frequency working mode. For the HSDPA service byte value of the multi-carrier/cell HSDPA service of the current terminal UE in cell B, within a period of time, in this embodiment, it is one In the time observation window, if it is higher than the pre-configured threshold, an Order command to activate the B cell will be triggered to enable the reception of the auxiliary carrier frequency and activate the B cell. the

In the embodiment (5), the Node B judges based on the ratio of ACK and NACK of the carrier frequency of the cell. The carrier frequency decision timing may be triggered by an event or periodically. the

After the terminal UE performs verification or receives information, it will send a reply message to Node B. If the reply message received by Node B is ACK, it indicates that the verification result or received information is correct; if the reply message received by Node B is NACK , it indicates that the verification result or received information is wrong. the

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

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

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

Step 54, A, B cells are in the dual-carrier carrier frequency co-working mode, within a period of time, in this embodiment, within a time observation window, the ratio of ACK to NACK for the carrier frequency of B cell is lower than the pre-configured threshold, Then an Order command to deactivate the B cell will be triggered to disable the reception of the carrier frequency of the secondary carrier, and the B cell will be deactivated. the

Step 55: Cell A is in the single-carrier carrier frequency working mode. After the timer configured on the Node B side expires, an Order command for activating Cell B will be triggered to enable reception of the carrier frequency of the auxiliary carrier and activate Cell B. After the B cell is deactivated, the Node B cannot receive the ACK and NACK messages of the carrier frequency of the B cell, so a timer needs to be used for timing activation. the

In this embodiment, after 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 all the data sent by the carrier/cell B Go back to the carrier/cell A to send. For the data packets that have been sent but have not received the HARQ response of the terminal UE, wait for the HARQ response of the terminal UE. If the response time has passed and the response or response of the terminal UE has not been received If it is NACK, the data will not be retransmitted on carrier/cell B, but transferred to carrier/cell A for retransmission. The retransmitted data should be sent preferentially on the carrier/cell A. For those data packets that are transferred from carrier/cell B to carrier/cell A, they are sent according to the sequence number of the RLC layer of the data, instead of putting them directly at the end of the data sequence in carrier/cell A. Figure 5 shows the data transmission status of the two carriers/cells when the carrier/cell B is deactivated, and Figure 7 shows the data in the queue corresponding to the carrier/cell B being transferred to the carrier/cell A after the carrier/cell B is deactivated Schematic diagram sent. If two carriers/cells share one MAC-hs/ehs queue, only the retransmitted data needs to be processed, and the transfer and insertion process of the queue is omitted. the

Instruct the terminal to deactivate the auxiliary carrier frequency. In this embodiment, the auxiliary carrier frequency is cell B, and then also include the data operation process of the auxiliary carrier frequency for terminal deactivation, specifically:

The data that has been sent by the auxiliary carrier frequency but has not received a response, waiting for a response;

Data that has been sent by the auxiliary carrier frequency but has not received a response within the response time or received a failed response will be resent by other carrier frequencies;

The data not sent by the auxiliary carrier frequency is transferred to the sending sequence of other carrier frequency for sending or discarding the data according to the sequence number of the data. the

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

The technical solution of the embodiment of the present invention flexibly activates and deactivates a certain carrier frequency through Node B control, improves the system capacity, and achieves a better effect of load balancing. the

Step 2, the RNC sends the carrier frequency report condition to the terminal UE through the node Node B forwarding;

Step 3, the terminal UE forwards the response information to the RNC via the Node B;

Step 4. Cells A and B are mutually multi-carrier frequency cells, and cells A and B are in dual-carrier frequency working mode. If the terminal UE is in a period of time, which is a time observation window in this embodiment, if the carrier frequency of cell B is downlink When the bit error rate is higher than the pre-configured threshold of the downlink bit error rate, the terminal UE reports an event to notify the RNC, and the RNC will trigger an Order command to deactivate the B cell through the Node B to close the acceptance of the auxiliary carrier frequency and deactivate the B cell. The terminal UE may also periodically report the bit error rate of the cell. the

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 at this time. After the timer expires, the RNC will trigger the trigger through the Node B.

Send an Order command to activate cell B. After the B cell is deactivated, the terminal UE cannot report the bit error rate of the B cell, so a timer needs to be used to activate it regularly. the

The technical scheme of the embodiment of the present invention flexibly activates and deactivates a certain carrier frequency through RNC control, improves the system capacity, and achieves a better effect of load balancing. the
