Description

Resource allocation method, device and system

Technical Field

The present invention relates to mobile communication technologies, and in particular, to a method, an apparatus, and a system for resource allocation.

Background

In the field of mobile communication, with the development of various services, users have made higher and higher demands on the speed of data transmission. In order to support higher-Speed data service, lower time delay, higher throughput and spectrum utilization rate, two new technologies are proposed, namely High Speed Downlink Packet Access (HSDPA) and High Speed Uplink Packet Access (HSUPA).

The HSUPA technology introduces a new Physical Channel, which includes an E-DCH Dedicated Physical Data Channel (E-DPDCH) for carrying uplink Data information of an Enhanced Dedicated Channel (E-DCH), and an E-DCH Dedicated Physical Control Channel (E-DPCCH) for carrying uplink signaling information of the E-DCH.

Before the new Physical Channel is introduced, the data rate is increased, and the data block for transmitting data is increased, so that the performance of Channel estimation according to a Dedicated Physical Control Channel (DPCCH) is poor, and the performance requirement of high-speed data transmission demodulation cannot be met. The above problems are mainly caused by: in order to optimize the performance of uplink high-speed transmission, the power difference between the E-DPDCH and the DPCCH needs to be controlled within a certain range, and the power of the DPCCH needs to be increased and the DPCCH signal-to-noise ratio (DPCCH SIR) needs to be increased at the same time to ensure that the power difference is controlled within a certain range. However, the Outer Loop Power Control (OLPC) process of adjusting the Signal-to-Interference ratio target (SIRtar) is a slow process, and if the SIR is adjusted too fast, the OLPC may not keep up with the SIR change. Thus, it may occur that SIRtar is still at a low value when a large SIR is required at high speed. In this case, the bit error rate is greatly increased at high speed, and the throughput is seriously affected.

Therefore, after the introduction of the E-DPCCH, in order to improve the accuracy of channel estimation, the E-DPCCH is also added to the channel estimation. When the E-DPCCH is added with the channel estimation, the power boost characteristic of the E-DPCCH enables the power difference between the E-DPCCH and the E-DPDCH to be controlled within a performance allowable range, and meanwhile the requirement of the signal to noise ratio during power change can be met. Thus, the accuracy of channel estimation is greatly improved.

However, in the prior art, a Radio Network Controller (RNC) cannot allocate E-DPCCH power boost resources to a Radio link of a UE with E-DPCCH power boost capability when performing resource configuration. Therefore, even if the UE has the E-DPCCH power boost capability and cannot utilize the power boost characteristic of the E-DPCCH to carry out channel estimation, the problems that the channel estimation is inaccurate and the data demodulation performance is poor when high-speed data transmission still exists.

Detailed Description

In order to make the objects, technical solutions and advantages of the present invention more apparent, the present invention will be described in further detail with reference to the accompanying drawings.

In the following embodiments, the wireless communication system is exemplified by a WCDMA (Wideband Code Division multiple access) system, but may be generally applied to other wireless communication systems, for example, an LTE (Long Term Evolution) system. The RNC, Node B and UE in other wireless communication systems have different names, but the embodiments of the present invention may also be applied.

When a Radio Resource control (RRC Connection) Connection is established between the UE and the Node B, the UE reports to the RNC whether the UE has the E-DPCCH power boost capability in an RRC Connection Request (RRC Connection Request) message or an RRC Connection Setup Complete (RRC Connection Setup Complete) message. However, when the RNC synchronizes the configuration and capability information of the Node B with the Node B, the Node B may not actively report whether the Node B has the E-DPCCH power boost capability. Therefore, the RNC cannot correctly acquire the capability information of the Node B, and cannot correctly allocate the radio resources.

For example, the RNC may default that the RNC does not report or does not have the E-DPCCH power boost capability, and when performing Radio Link (RL) configuration or RL reconfiguration, the Node B is not notified to allocate E-DPCCH power boost resources for the current Radio Link of the UE. That is, the Node B does not use the E-DPCCHpower boost feature for channel estimation for the current UE. In this case, even if the UE has the E-DPCCH power boost capability, the UE and the Node B still use the DPCCH for channel estimation, which causes the problems of low accuracy of channel estimation and high error rate during high-speed data transmission.

Therefore, there is a need for the RNC to be able to know explicitly whether the Node B has the capability of E-DPCCH power boost in order to configure the optimal radio resources for the Node B and the UE.

As shown in fig. 1, a first embodiment of the present invention provides a method for resource allocation, which includes:

step 101, acquiring capability information of Node B, wherein the capability information comprises whether the Node B has E-DPCCHpower boost capability;

step 102, acquiring the capability information of the UE, wherein the capability information comprises whether the UE has the E-DPCCH powerboost capability;

step 103, when both UE and Node B have E-DPCCH Power boost capability, informing the Node B to configure the resource for channel estimation by adopting channel Power boost capability for the current UE.

Specific implementations of the steps of this embodiment will be described in detail in the following embodiments.

In this embodiment, the capability information of the Node B and the capability information of the UE are acquired by the RNC, and the resource that the Node B is optimal for channel estimation is configured for the current UE according to the acquired capability information, so that when both the UE and the Node B have the channel power elevation capability, the Node B can perform channel estimation by using the channel power elevation capability, thereby improving the accuracy of channel estimation and reducing the error rate of high-speed data transmission.

A second embodiment of the present invention will be described in detail below with reference to fig. 2. A second embodiment of the present invention also provides a method for resource allocation, including:

step 201, RNC and Node B synchronize Node B configuration and capability information.

In step 201, the RNC may synchronize the configuration and capability information of the Node B through a resource auditing process, a resource status indicating process, or a combination of both.

When the configuration and capability information of the RNC and the Node B are synchronized through the resource auditing process, the RNC sends a resource auditing request to the Node B to start the resource auditing process. In the process, the RNC acquires the configuration condition, the capability information and the like of the Node B through the resource audit response message sent by the Node B. Through the process, the RNC can complete the synchronization of the Node B configuration situation and the logic resource state.

In order to make the RNC know explicitly whether the Node B has the capability of the E-DPCCH power boost, the Node B carries an Information Element (IE) in the resource audit response message for indicating that the Node B has the capability of the E-DPCCH power boost or does not have the capability.

Therefore, the RNC can definitely know whether the Node B can use the E-DPCCHpower boost characteristic or not through the IE which is carried in the resource audit response message and indicates whether the Node B has the E-DPCCHpower boost capability or not.

The resource audit process may be triggered in a variety of situations, not necessarily before the following steps are performed. For example, when the RNC starts up, switches or the cell condition changes, the RNC will initiate a resource audit process.

When the RNC and the Node B finish the configuration and the capability information of the Node B synchronously through the resource state indicating process, the RNC receives the resource state indicating information sent by the Node B and finishes the synchronization of the configuration and the capability information of the Node B according to the information. The resource status indication message carries a plurality of IEs for indicating the Node B configuration condition and the logic resource status, wherein the IEs for indicating whether the Node B has the E-DPCCH power boost capability are included.

The RNC can definitely know whether the Node B can use the E-DPCCH power boost characteristic to carry out channel estimation or not through the IE which is carried in the resource state indication message and whether the Node B has the E-DPCCH power boost capability or not.

The Node B sending the resource status indication message to the RNC may be triggered in many cases and does not have to be done before the subsequent steps are performed. For example, adding a local cell of a Node B; deleting the local cell of the Node B; the Node B may be triggered to send a resource status indication message to the RNC when the capability of the local cell changes.

The resource auditing process and the resource state indicating process can be realized, so that the RNC can definitely know whether the Node B has the E-DPCCH power boost capability. Meanwhile, the combination of the two can also complete the synchronization process of the RNC acquiring the capability information of the Node B. Because the triggering conditions of the resource auditing process and the resource state indicating process are different, the triggering of the resource auditing process and the resource state indicating process does not exist in sequence, mutual exclusion does not exist, and the triggering conditions can be combined for use, so that the method can more comprehensively ensure that when the UE initiates RRC connection establishment, the RNC can accurately know whether the Node B can use the E-DPCCH powerboost characteristic for channel estimation, better ensure the accuracy of the channel estimation between the UE and the Node B, and reduce the error rate of high-speed data transmission between the UE and the Node B.

Step 202, the RNC receives a message sent by the UE to obtain the capability of the UE.

When the UE initiates an RRC Connection, the UE may start an RRC Connection establishment procedure by sending an RRC Connection Request message to the RNC. In the RRC Connection Request message, part of the UE capability is carried. In the RRC Connection Setup Complete message sent by the UE to the RNC, the capability of all UEs not carried in the RRC Connection Request message may be carried. By receiving the two messages, the RNC can learn the full capabilities of the UE.

The RNC knows all the capabilities of the UE through the two messages, including whether the UE has the E-DPCCHpower boost capability. Therefore, the RNC can explicitly know whether the UE has the E-DPCCHpower boost capability through the RRC connection establishment procedure.

Step 203, RNC configures Node B resource for UE according to UE capability.

After receiving the RRC Connection Request message sent by the UE, the RNC notifies the Node B to configure resources on the Node B for the UE, that is, to establish the RL, according to a partial capability of the UE carried in the message. And, after receiving the RRC Connection Setup Complete message sent by the UE and knowing the full capability of the UE, the RNC notifies the Node B of the reconfiguration of the Node B resources, that is, the RL reconfiguration, according to the full capability of the UE.

Through step 201, the RNC explicitly knows whether the Node B has the E-DPCCH power boost capability; the RNC explicitly knows whether the UE has E-DPCCH power boost capability, via step 202. Therefore, in step 203, the RNC can optimally configure the resources of the Node B for the UE through the RL setup and RL reconfiguration process. For example, when both Node B and UE have E-DPCCH power boost capability, RNC can inform Node B to perform resource allocation to current UE to perform channel estimation by using E-DPCCH power boost characteristic through RL establishment procedure and RL reconfiguration procedure, thereby improving channel estimation accuracy.

Through the above steps of this embodiment, the RNC can clearly know whether the Node B has the E-DPCCH power boost capability, so that when both the UE and the Node B have the E-DPCCH power boost capability, the Node B is configured for the current UE to perform channel estimation using the E-DPCCH power boost characteristic. According to the embodiment, when the RNC configures the Node B to perform channel estimation by using the E-DPCCH power boost characteristic, the accuracy of the channel estimation of the UE and the Node B can be improved, thereby ensuring the accuracy of high-speed data transmission between the UE and the Node B and improving the throughput.

In addition, after the RNC has configured the resource of the Node B, the RNC may further configure the resource at the UE, for example, configure the resource at the UE through a Radio Bearer (RB) establishment or RB reconfiguration process, so as to achieve the consistency between the resource configuration of the UE and the resource configuration of the Node B.

A third embodiment of the present invention will be described in detail with reference to fig. 3. The third embodiment of the present invention provides a method for resource allocation in a UE moving process, where the method includes:

in step 301, the Drift RNC (Drift RNC, DRNC) synchronizes the Node B configuration and capability information with the Node B.

The DRNC synchronizes the configuration and capability information of the Node B with the Node B through a resource auditing process or a resource status indicating process, or a combination of both, so as to know whether the Node B has the E-DPCCHpower boost capability, which is specifically implemented with reference to step 201 in the second embodiment of the present invention.

Step 302, the Serving RNC (SRNC) receives the message sent by the UE to obtain the capability of the UE.

The UE reports all the capabilities to the SRNC through the RRC connection establishment process. Accordingly, the SRNC can definitely know whether the UE has the E-DPCCH power boost capability. The specific implementation refers to step 202 in the second embodiment of the present invention.

Step 303, SRNC gets Node B capability information.

The DRNC can forward the capability information of the Node B acquired by the DRNC through the synchronization process to the SRNC, so that the SRNC can definitely acquire whether the Node B has the E-DPCCH capability.

For example, the DRNC may inform the SRNC whether the Node B can perform channel estimation using the E-DPCCH power boost feature by adding an IE for indicating whether the Node B has the E-DPCCH power boost capability in an Uplink Signaling transfer indication (Uplink Signaling transfer) message.

For example, the DRNC may also inform the SRNC whether the Node B can use the E-DPCCH power boost feature for channel estimation by adding an IE to indicate whether the Node B has E-DPCCH power boost capability in an RL Response (RL Response) message.

The DRNC may also forward the Node B capability information to the SRNC through other interaction messages with the SRNC, and is not limited to the above two manners.

Step 304, SRNC configures Node B resource for UE according to current UE capability.

In step 303, the SRNC explicitly learns whether the Node B has the E-DPCCH powerboost capability through the forwarding of the DRNC. Therefore, when configuring the resources of the Node B for the UE, the RNC can configure the Node B for the UE according to whether the UE has the E-DPCCH power boost capability or not to use the E-DPCCH power boost characteristic for channel estimation. The specific implementation of the configuration can refer to step 203 in the second embodiment of the present invention.

In this embodiment, there is no specific order in execution between step 301 and step 302. Because step 301 knows the Node B capability information for DRNC, step 302 learns the UE capability information for SRNC, and these two steps are completed by DRNC and SRNC respectively, and there is no specific association, so there is no specific sequence in execution. Step 303 needs to be performed after step 301 because the DRNC knows the Node B capabilities before it can forward them to the SRNC. However, there is no specific sequence between step 303 and step 302, because step 302 is that the SRNC learns the UE capability, and step 303 is that the DRNC forwards the Node B capability to the SRNC, there is no specific association between them, so there is no specific execution sequence.

According to the third embodiment of the present invention, the DRNC may explicitly know whether the Node B has the E-DPCCH power boost capability through a resource auditing procedure, a resource status indicating procedure, or a combination of both. Through DRNC transmitting Node B to SRNC whether having E-DPCCH power boost capability, SRNC can know definitely whether Node B can use the characteristic to carry out channel estimation. Thus, the SRNC knows explicitly whether the UE and Node B have the capability of the E-DPCCH power boost. Therefore, when both the UE and the Node B have the E-DPCCH power boost capability, the Node B is configured for the UE to carry out channel estimation by using the E-DPCCH power boost characteristic, so that the accuracy of the channel estimation of the UE in a mobile scene can be improved, and the error rate of high-speed data transmission in the scene can be reduced.

In addition, after the RNC configures the resources of the Node B, the resources at the UE can be further configured so as to achieve the consistency of the resource configuration of the UE and the Node B.

A fourth embodiment of the present invention will be described in detail with reference to fig. 4. A fourth embodiment provides a method for resource allocation, the method comprising:

in step 401, the RNC learns the UE capability information.

In the process of initiating RRC connection establishment, the UE reports all capability information to the RNC, so that the RNC can definitely know whether the UE has the E-DPCCH power boost capability. The specific implementation can refer to step 202 in the second embodiment of the present invention.

Step 402, RNC configures the resource on Node B according to the capability of UE.

When synchronizing the capability information with RNC, Node B does not report whether it has E-DPCCH power boost capability, at this time, RNC defaults that the Node B has E-DPCCH power boost capability. Therefore, when the RNC configures the resources on the Node B for the UE according to the current capability of the UE, if the UE has the E-DPCCH power boost capability, the RNC can use the E-DPCCH power boost characteristic for the configured Node B to carry out channel estimation.

Therefore, the RNC configures the Node B with the E-DPCCHpower boost related parameters in the process of RL establishment or RL reconfiguration.

In step 403, the RNC reconfigures the resources on the Node B according to the feedback of the Node B.

When the Node B does not have the E-DPCCH power boost capability, the radio link establishment failure message is fed back to the RNC, and the reason of the establishment failure is carried in the radio link establishment failure message. If the radio link establishment failure is due to the Node B not having the E-DPCCH power boost capability, the failure reason that the Node B feeds back to the RNC includes an indication that the Node B does not have the E-DPCCH power boost capability.

After RNC receives the failure reason fed back by Node B, it can clearly know that said Node B has no E-DPCCH power boost capability, then re-initiate the establishment of radio link, and in the establishment request no longer configure the relevant parameters of E-DPCCH power boost for Node B.

In this embodiment, step 403 does not need to be executed, if Node B has E-DPCCHpower boost capability, then step 403 does not need to be executed, because when Node B has this capability, it can use this characteristic to perform channel estimation, and thus no radio link establishment failure is returned.

According to the fourth embodiment of the present invention, in the synchronization process, the RNC defaults that the Node B has the E-DPCCH power boost capability because the Node B does not report whether the Node B has the E-DPCCH power boost capability, so when the UE has the E-DPCCH power boost capability, the RNC defaults that the Node B has the E-DPCCH power boost capability and configures the Node B for the UE to perform channel estimation using the E-DPCCH power boost characteristic, thereby improving the quality of channel estimation and reducing the error rate during high-speed data transmission.

In addition, according to the fourth embodiment of the present invention, when the Node B does not have the E-DPCCH power boost capability, although the RNC may default that the Node B has the capability because the Node B does not report whether it has the capability in the synchronization process, the capability of the Node B may still be specified in the reconfiguration process, and the problem of inconsistent configuration for the Node B and the UE may not be caused.

The fifth embodiment of the present invention will be described in detail with reference to fig. 5. A fifth embodiment provides a method for resource configuration of a UE during mobility, where the method includes:

step 501, the SRNC learns the capability of the UE, and the specific implementation thereof can refer to step 302 in the third embodiment of the present invention.

Step 502, SRNC configures Node B resource for current UE capability.

When Node B and DRNC synchronize Node B ability information, Node B does not report whether it has E-DPCCH power boost ability, DRNC defaults the Node B to have E-DPCCH power boost ability.

When DRNC transmits Node B ability information to SRNC, it will not transmit whether Node B has E-DPCCHpower boost ability, at this time SRNC will default Node B has E-DPCCHpower boost ability.

Therefore, when the SRNC configures the resource of the Node B for the UE, if the UE has the E-DPCCH power boost capability, the SRNC configures the Node B for the UE and carries out channel estimation by using the E-DPCCH power boost characteristic. At this time, the RL setup or RL reconfiguration message sent by the SRNC to the DRNC may carry E-DPCCH power boost related parameters, and the RL setup or RL reconfiguration message sent by the DRNC to the Node B may also carry E-DPCCH power boost related parameters.

Step 503, SRNC reconfigures Node B resource according to Node B feedback.

When Node B does not have E-DPCCH power boost capability, if UE has the capability, SRNC configures Node B for UE to use E-DPCCH power boost characteristic for channel estimation because default Node B has the capability.

At this time, the Node B may feed back an RL setup failure message to the DRNC because it does not have the E-DPCCH power boost capability, and the message carries a failure reason indicating that the Node B does not have the capability. After receiving RL establishment failure message fed back by the Node B, the DRNC feeds back RL establishment failure to the SRNC, and carries failure reason to indicate that the Node B does not have E-DPCCHpower boost capability. After SRNC knows that RL establishment failure is caused by Node B not having E-DPCCH power boost capability, SRNC re-initiates RL establishment or RL reconfiguration, and does not configure E-DPCCH power boost related parameters in RL establishment or RL reconfiguration request.

According to the fifth embodiment of the present invention, the DRNC defaults to Node B having E-DPCCHpower boost capability during synchronization because Node B does not report that capability, and thus the SRNC also defaults to Node B having that capability. Therefore, when the UE has the E-DPCCH power boost capability, the Node B is configured for the UE to carry out channel estimation by using the E-DPCCH power boost characteristic because the Node B is defaulted to have the E-DPCCH power boost capability by the SRNC, thereby improving the quality of channel estimation and reducing the error rate during high-speed data transmission.

In addition, according to the fourth embodiment of the present invention, when the Node B does not have the E-DPCCH power boost capability, although the DRNC may default that the Node B has the capability because the Node B does not report whether it has the capability during the synchronization process, the SRNC may also default that the Node B has the capability accordingly. However, the SRNC can still reconfigure the resource of the Node B through the Node B feedback failure reason, and the problem of inconsistent configuration of the Node B and the UE can not be caused.

It can be known from the fourth embodiment and the fifth embodiment of the present invention that, when the RNC in the fourth embodiment is the SRNC, the method provided in the fourth embodiment can also implement the problem of resource allocation in the mobile scenario in the fifth embodiment. In the fifth embodiment, the DRNC does not have a decision function, but performs a transfer process, and the SRNC still finally grasps the capability information of the UE and the Node B, and performs resource configuration according to the capability information of the UE and the Node B.

The sixth embodiment of the present invention will be described in detail below with reference to fig. 6. A sixth embodiment provides a method for resource allocation, including:

in step 601, the RNC obtains the capability information of the UE, and the specific implementation manner of the RNC is shown in step 202 in the second embodiment of the present invention.

Step 602, RNC configures Node B resource for UE according to current UE capability.

In the synchronization process of RNC and Node B, Node B will not report whether it has E-DPCCH power boost capability. In this case, the RNC defaults to the Node B having E-DPCCH power boost capability.

Therefore, when the UE has E-DPCCH power boost capability, the RNC configures the Node B for the UE to perform channel estimation by using the E-DPCCH power boost characteristic.

Step 603, Node B configures resources according to its own capability.

When a Node B does not have E-DPCCH power boost capability, if the UE has the capability, the RNC configures E-DPCCH power boost related parameters for the Node B because the default Node B has the capability. At this time, the Node B may use DPCCH for channel estimation because it does not have this capability.

The resource allocation method provided in the present embodiment may also be applied in a mobile scenario. In a mobile scenario, the RNC in this embodiment is an SRNC, the SRNC forwards and acquires capability information of a Node B through a DRNC, and defaults the Node B to have the capability when the unrewarded Node B has the E-DPCCH power boost capability. Therefore, the SRNC configures E-DPCCH power boost related parameters for Node B when the UE has E-DPCCH power boost capability. Node B will decide whether to adopt E-DPCCH power boost characteristic to carry out channel estimation according to its own capability.

According to the sixth embodiment of the present invention, the RNC defaults the Node B to have E-DPCCH power boost capability when the Node B does not report whether it has the capability, and configures E-DPCCH power boost related parameters for the Node B in case the UE has the E-DPCCH power boost capability. Therefore, when both the UE and the Node B have the E-DPCCH power boost capability, the RNC can enable the UE and the Node B to carry out channel analysis by adopting the characteristics through resource configuration, improve the accuracy of the channel analysis and reduce the error rate of high-speed data transmission.

The seventh embodiment of the present invention will be described in detail with reference to fig. 7. The seventh embodiment provides an RNC710, the RNC710 comprising:

a receiving module 711, configured to receive capability information reported by a Node B720 and a UE730, where the capability information reported by the Node B720 includes an IE indicating whether the Node B720 has a channel power raising capability;

the notifying module 712, if both the UE730 and the Node B720 have the capability of raising the channel power, is configured to notify the Node B720 to configure a resource for the UE730 to perform channel estimation by using the capability of raising the channel power.

The receiving module 711 receives a resource audit response message or a resource status indication message sent by the Node B720, where the message carries an IE indicating whether the Node B720 has the E-DPCCH power boost capability. The receiving module 711 may also be configured to receive an IE forwarded by another RNC indicating the capability of the Node B720. From this, it can be known whether the Node B720 has E-DPCCH power boost capability.

The receiving module 711 may also receive an RRC connection request or an RRC connection setup complete message sent by the UE730, where the message carries all the capabilities of the UE 730. Thus, it can be known whether the UE730 has E-DPCCH power boost capability.

The notification module 712 sends a notification to the Node B720 to configure the E-DPCCH power boost when both the UE730 and the Node B720 have E-DPCCH power boost capability.

In addition, the notifying module 712 may be further configured to send parameters related to the resource configuration to the UE730, i.e., notify the UE730 to configure the corresponding resource.

The RNC provided in the seventh embodiment of the present invention can definitely know whether a Node B has an E-DPCCH power boost capability through capability information sent by the Node B in a scenario where the UE is moving or not, so that when the UE has the capability and the Node B also has the capability, the Node B is configured for the UE to perform channel estimation by using the E-DPCCH power boost characteristic, thereby improving accuracy of channel estimation and reducing an error rate of high-speed data transmission.

The eighth embodiment of the present invention will be described in detail below with reference to fig. 7. An eighth embodiment provides a Node B720, the Node B720 comprising:

a receiving module 721, configured to receive relevant parameters for configuring Node B channel estimation resources sent by the RNC;

a sending module 722, configured to send capability information of the Node B720 to the RNC 710;

a processing module 723, configured to add an IE indicating whether the Node B720 has the E-DPCCH power boost capability in the sent capability information according to whether the Node B720 has the E-DPCCH power boost capability.

When the receiving module 721 receives the resource audit request message sent by the RNC710, the processing module 723 adds an IE indicating whether the Node B720 has the E-DPCCH power boost capability in the resource audit response message according to whether the Node B720 has the E-DPCCH power boost capability, and sends the resource audit response message through the sending module 722.

The sending module 722 may also be configured to send the capability information of the Node B720 to other RNCs, and the RNC forwards the capability information of the Node B720 to the RNC 710.

The processing module 723 is further configured to add an IE indicating whether the Node B720 has the E-DPCCH power boost capability in a resource status indication message for synchronizing the Node B resources according to whether the Node B720 has the E-DPCCH power boost capability, and send the resource status indication message through the sending module 722.

The processing module 723 is further configured to configure resources of the NodeB720 according to the configuration parameter sent by the RNC710 and received by the receiving module 721. For example, when the receiving module 721 receives the parameters related to configuring the E-DPCCH power boost, the processing module 723 configures the Node B720 to perform channel estimation by using the E-DPCCH power boost characteristic.

The Node B provided in the eighth embodiment of the present invention can explicitly indicate whether the RNC has the E-DPCCH power boost capability when indicating the capability information of the RNC, so that the RNC can explicitly know whether the Node B can perform channel estimation by using the E-DPCCH power boost characteristic. Therefore, when both UE and Node B have E-DPCCH power boost capability, RNC can configure NodeB for UE to adopt E-DPCCH power boost characteristic to carry out channel estimation, thereby improving accuracy of channel estimation and reducing error rate of high-speed data transmission.

The ninth embodiment of the present invention is described below in detail with reference to the seventh embodiment of the present invention. A ninth embodiment provides another RNC comprising:

a receiving module, configured to receive capability information reported by a Node B and a UE;

a notification module, which defaults Node B to have the capability when the capability information reported by Node B does not include the capability of indicating whether Node B has E-DPCCHpower boost capability; and informing the Node B to configure the UE to adopt the channel lifting capability to carry out channel estimation or adopt a special physical control channel to carry out channel estimation according to the capabilities of the UE and the Node B.

The receiving module receives a resource audit response message or a resource state indication message sent by the Node B, or capability information of the Node B forwarded by other RNC, wherein the message does not carry IE for indicating whether the Node B has the E-DPCCH powerboost capability. The notification module is used for defaulting the Node to have the capability when the message does not carry the IE for indicating whether the Node B has the E-DPCCH powerboost capability, and notifying the Node B to configure the resource for the UE to adopt the channel lifting capability for channel estimation.

The notification module notifies the Node B to configure the resource for the UE to perform channel estimation by adopting the channel lifting capability when the capability information of the UE received by the receiving module comprises information indicating that the UE has the E-DPCCH powerboost capability.

In addition, the receiving module is also used for receiving the feedback of RL establishment failure sent by the Node B; and the notification module is used for sending a request message for RL establishment or reconfiguration according to failure information which is contained in the feedback and indicates that the Node B does not have the E-DPCCH power boost capability, and the request message does not contain relevant parameters for configuring the E-DPCCH power boost, namely, the notification module notifies the Node B to configure resources for UE to adopt a special physical control channel for channel estimation.

In the RNC according to the ninth embodiment of the present invention, when the capability information reported by the Node B does not include the capability of the E-DPCCH power boost, the Node B may be determined to have the capability. Therefore, under the mobile or non-mobile scene including the UE, as long as the UE has the E-DPCCH power boost capability, the RNC can configure the Node B for the UE to carry out channel estimation by adopting the E-DPCCH power boost characteristic, thereby improving the accuracy of the channel estimation and reducing the error rate of high-speed data transmission.

In addition, when the Node B does not have the E-DPCCH power boost capability, the RNC provided in the ninth embodiment may re-perform RL setup or RL reconfiguration according to the failure cause fed back by the Node B, and does not re-configure the Node B to perform channel estimation by using the E-DPCCH power boost characteristic, thereby ensuring the consistency of the resource configuration of the Node B and the UE.

The tenth embodiment of the present invention will be described in detail below with reference to the eighth embodiment of the present invention. A tenth embodiment provides another Node B, including:

a receiving module, configured to receive a notification of configured related resources sent by an RNC;

a sending module, configured to send capability information of a Node B to an RNC, where the capability information does not include whether the Node B has an E-DPCCH power boost capability;

and the processing module is used for configuring resources used by the Node B for channel estimation for the UE.

And a sending module, when the Node B does not have the E-DPCCH power boost capability and receives the relevant parameters configuring the E-DPCCH power boost, the RNC710 sends an RL setup failure message, and the message carries the failure reason. Wherein the failure reason indicates that the Node B does not have the capability of the E-DPCCHpower boost;

the processing module is used for configuring the Node B to adopt the E-DPCCH power boost characteristic to carry out channel estimation for the current UE when the Node B has the E-DPCCH power boost capability and receives the relevant parameters for configuring the E-DPCCH power boost.

The notification module may also be configured to send capability information of the Node B to other RNCs, and the RNC that receives the capability information may forward the capability information.

The Node B provided in the tenth embodiment of the present invention may configure the Node B for the UE to perform channel estimation using the E-DPCCH power boost characteristic when the Node B has the E-DPCCH power boost capability and receives the configuration E-DPCCH power boost related parameter sent by the RNC, thereby improving the accuracy of channel estimation and reducing the error rate of high-speed data transmission. Or when the Node B does not have the E-DPCCH power boost capability and receives the relevant parameters for configuring the E-DPCCH power boost sent by the RNC, the reason for the failure of the feedback RL establishment is that the Node B does not have the E-DPCCH power boost capability, so that the RNC can definitely know that the Node B does not have the E-DPCCH power boost capability, and when the Node B is reconfigured, corresponding parameters are not configured for the Node B any more, thereby ensuring the consistency of the resource configuration of the UE and the Node B.

The eleventh embodiment of the present invention will be described below in detail with reference to the eighth embodiment of the present invention. An eleventh embodiment provides another Node B, comprising:

a receiving module 721, configured to receive a notification of configured related resources sent by the RNC;

a sending module, configured to send capability information of the Node B to the RNC, where the capability information does not include whether the Node B has an E-DPCCH power boost capability;

a processing module, when the Node B does not have the E-DPCCH power boost capability and receives the relevant parameters for configuring the E-DPCCH power boost, the Node B is configured not to adopt the E-DPCCH power boost characteristic for channel estimation; and when the Node B has the E-DPCCH power boost capability and receives the relevant parameters for configuring the E-DPCCH power boost, configuring the Node B to adopt the E-DPCCH power boost characteristic for the current UE to carry out channel estimation.

The sending module may also be configured to send the capability information of the Node B to other RNCs, and the RNC that receives the capability information may forward the capability information.

The Node B provided in the eleventh embodiment of the present invention may configure the Node B for the UE to perform channel estimation using the E-DPCCH power boost characteristic when the Node B has the E-DPCCH power boost capability and receives the configured E-DPCCH power boost related parameter sent by the RNC, thereby improving the accuracy of channel estimation and reducing the error rate of high-speed data transmission. Or when the Node B does not have the E-DPCCH power boost capability and receives the relevant parameters of the configuration E-DPCCH power boost sent by the RNC, the configuration Node B does not adopt the E-DPCCH power boost characteristic to carry out channel estimation, thereby enabling the wireless link to be successfully established.

The twelfth embodiment of the present invention will be described in detail with reference to fig. 7. A twelfth embodiment provides a system for resource allocation, including:

RNC710, used for receiving the capability information sent by Node B720 and UE 730; configuring Node B resources according to the capability information sent by Node B720 and UE 730;

node B720, for sending the capability information of Node B720; configuring the resources of the NodeB720 according to the configuration parameters of the RNC 710;

the UE730 is configured to send capability information of the UE 730.

The RNC710 can receive the information indicating the Node B720 capability sent by the Node B720 through the resource auditing process or the resource status indicating process, wherein the information includes the information indicating whether the Node B720 has the E-DPCCH power boost capability. The RNC710 sends configuration E-DPCCH power boost related parameters to the Node B720 when both the UE730 and the Node B720 have E-DPCCH power boost capability.

The Node B720 sends the capability information of the Node B720 through the resource audit response message or the resource status indication message, wherein the capability information comprises IE which indicates whether the Node B has the E-DPCCH power boost capability.

The UE730 sends its entire capability information to the RNC through the RRC connection establishment procedure.

In addition, the Node B720 may also send its capability information to other RNCs, and the RNC710 may receive the Node B720 capability information forwarded by the RNC.

Furthermore, when the capability information sent by the Node B720 does not include the IE indicating whether the Node B has the E-DPCCH power boost capability, the RNC710 may default that the Node B720 has the capability, and when the capability information reported by the UE730 includes the IE indicating the E-DPCCH power boost capability, the RNC710 sends the Node B720 the parameters related to configuring the E-DPCCH power boost.

In addition, when the Node B720 does not have the E-DPCCH power boost capability and receives the configuration E-DPCCH power boost related parameter sent by the RNC710, the Node B720 feeds back the RL setup failure reason, which indicates that the Node B720 does not have the E-DPCCH power boost capability.

In addition, the RNC710 may be further configured to send an RL setup or RL reconfiguration request to the Node B720 again when receiving a failure reason fed back by the Node B720 indicating that the Node B does not have the E-DPCCH power boost capability, where the RL setup or RL reconfiguration request does not configure any more E-DPCCH power boost related parameters.

In addition, when the Node B720 does not have the E-DPCCH power boost capability and receives the configuration E-DPCCH power boost related parameter, the Node B720 may further configure the Node B720 not to adopt the E-DPCCH power boost characteristic for channel estimation.

In addition, with the above embodiments, the present embodiment may also be applied in a scenario where the UE moves, where the RNC is an SRNC and performs information interaction with a Node B through a DRNC.

The system provided by the twelfth embodiment of the present invention can configure the Node B for the UE to perform channel estimation by using the E-DPCCH power boost characteristic when the Node B capability information includes the IE indicating whether the Node B has the E-DPCCH power boost capability, according to the capabilities of the UE and the Node B, and both have the E-DPCCH power boost capability, thereby improving the accuracy of channel estimation and reducing the error rate of high-speed data transmission.

In addition, the system provided in the twelfth embodiment may also be configured such that when the Node B capability information does not include an IE indicating whether the Node B has the E-DPCCH power boost capability, the RNC defaults that the Node B has the E-DPCCH power boost capability, and thus when the UE has the E-DPCCH power boost capability, the Node B is configured for the UE to perform channel estimation by using the E-DPCCH power boost characteristic, so as to improve accuracy of channel estimation and reduce an error rate of high-speed data transmission.

In addition, the system provided in the twelfth embodiment may further indicate, when the Node B does not have the E-DPCCH power boost capability and receives the configuration E-DPCCH power boost related parameter sent by the RNC, that the Node B does not have the E-DPCCH power boost capability through the feedback failure reason, and the RNC re-establishes or re-configures the RL based on the result, and does not re-configure the Node B to perform channel estimation using the E-DPCCH power boost characteristic, thereby ensuring the consistency of the resource configurations of the Node B and the UE.

In addition, the system provided in the twelfth embodiment may configure the Node B not to use the E-DPCCH power boost characteristic for channel estimation when the Node B does not have the E-DPCCH power boost capability and receives the configured E-DPCCH power boost related parameter sent by the RNC, so that the radio link may be successfully established.

The above embodiments of the present invention can be combined, and the combination can better ensure the accuracy of Node B and UE channel estimation and the accuracy of high-speed data transmission. While the invention has been shown and described with reference to certain preferred embodiments thereof, it will be understood by those skilled in the art that various changes in form and details may be made therein without departing from the spirit and scope of the invention.
