Description

Channel configuration and allocation method suitable for multi-carrier high-speed downlink packet access

technical field

The present invention relates to the field of wireless communication, in particular, in a Time Division Synchronization Code Division Multiple Access (TD-SCDMA) system, a multi-carrier High Speed Downlink Packet Access (HSDPA) ) technology implementation method.

Background technique

An important feature of the third-generation mobile communication system is the unbalanced traffic volume of the uplink and downlink, and the traffic volume of the downlink will generally be greater than that of the uplink. In response to this requirement, 3GPP (3rd Generation Partnership Project) introduced the HSDPA (High Speed Downlink Packet Access) feature into the 3G specification.

In the HSDPA feature, by introducing AMC (Adaptive Modulation and Coding, adaptive coding and modulation), HARQ (Hybrid Automatic Retransmission Request, hybrid automatic retransmission request) technology and related technologies to reduce network processing delay, to provide higher The rate of the downlink packet service is higher, which improves the efficiency of spectrum utilization.

AMC technology determines the current channel capacity according to the channel situation (channel state information CSI), and determines the appropriate coding and modulation mode according to the capacity, so as to send information to the maximum and achieve a relatively high rate; moreover, the channel quality change for each user , AMC can provide correspondingly variable modulation and coding schemes, thus improving the transmission rate and spectrum utilization.

HARQ is an error correction method that combines traditional ARQ (Automatic Retransmission Request) technology and FEC (Forward Error Correct) technology. The code sent by the sending end can not only detect errors, but also have certain error correction capabilities. After the receiving end receives the information, if the error is within the error correction capability, it will automatically correct the error. If it exceeds the error correction capability of the error correction code, but it can be detected, the receiving end will feed back the corresponding signal to the sending end, requesting to send side resend.

In HSDPA technology, HS-DSCH (High Speed Downlink Shared Channel) and MAC-hs (High Speed Media Access Control) sublayers are newly introduced. On the network side, MAC-hs is implemented in the Node B and is used for data transmission of the HS-DSCH transmission channel. In Node B, each cell has a MAC-hs entity (entity). MAC-hs not only completes HS-DSCH data processing and scheduling, but also manages the management and allocation of HSDPA physical resources. MAC-hs includes functional entities such as flow control, scheduling/priority control, HARQ function, TFRC selection (Transport Format and Resource Choice, transmission format and resource selection). In the MAC-hs entity on the Node B side, each UE corresponds to a HARQ entity and implements the N-Channel SAW (See And Wait) Protocol (N channel stop waiting protocol), that is, the HARQ entity implements N-channel-SAW -HARQ protocol. One HARQ entity corresponds to multiple HARQ processes. In the current 3GPP protocol on TD-SCDMA, a UE's HARQ entity can contain up to eight HARQ processes (processes), and different HARQ processes are identified by processID (process number) . One HS-DSCH TTI corresponds to one HARQ process. On the UE side, one UE has one MAC-hs entity, including HARQ function, distribution, reordering and decomposition function entities. The HARQ entity and the HARQ entity in the Node B are peer entities, including the same number of HARQ processes, and each process forms a one-to-one corresponding protocol entity with the process on the Node B side through the process Id, which is used for MAC-hs PDU ( protocol data unit) packet reception. If the receiving end receives the data correctly, the ACK signal is fed back through the uplink HS-SICH channel (high-speed shared information channel) described below, and the HARQ process on the Node B side releases the data packet. On the contrary, if it fails to receive correctly, buffer the soft data, and feed back the NAK signal through HS-SICH, and the sending side process resends the data packet, that is, the HARQ entity processes the retransmission of the MAC-hs PDU data packet according to the process.

In the TD-SCDMA system HSDPA technology, the newly introduced HS-DSCH transport channel is mapped to the newly introduced HS-PDSCH (High Speed Physical Downlink Shared Channel, high-speed physical downlink shared physical channel). The HS-PDSCH channel is shared by multiple users in the cell in a time-division or code-division manner. The transmission time interval TTI (Transmission Time Interval) of HS-PDSCH is 5ms. The HS-PDSCH carries the user's service data, and the relevant control information for HS-PDSCH reception is transmitted through the newly introduced accompanying HS-SCCH (High Speed Shared Control Channel), and the HS-SICH is used for the transmission of uplink feedback information . Therefore, these three physical channels form a physical layer closed loop, and they are all processed and transmitted in units of 5 ms TTI. This shorter TTI can better adapt to the time-varying characteristics of the wireless link. The control information carried on the HS-SCCH channel includes: HARQ Process ID, redundancy version, new data identifier, HS-SCCH cycle sequence number HCSN, UE ID, modulation mode MF, transport block size identifier, and physical channel resources; HS-SCCH The feedback information carried on the SICH channel includes: the recommended modulation mode RMF, the recommended transport block size RTBS, and the confirmation information ACK/NAK for correct transmission of data. In addition, for the transmission of RRC signaling, 3GPP also defined uplink and downlink accompanying dedicated physical channels in R5, which are used to carry RRC signaling related to HSDPA.

According to the current 3GPP protocol, in the TD-SCDMA system, there is a one-to-one correspondence between cells and carriers. The channel resource allocation method related to HSDPA in a single carrier cell is: one HS-DSCH, multiple HS-SCCHs, and HS-SICH corresponding to each HS-SCCH one by one. When configuring HS-DSCH resources for a UE on the network side, configure 1 to 4 HS-SCCHs to form an HS-SCCH set, and configure HS-SICHs corresponding to each HS-SCCH. In the process of sending HS-DSCH data, every HS-DSCH TTI, Node B sends the HS-DSCH related control channel on an HS-SCCH channel, and the UE obtains this information by reading the channel, and communicates with the HS - The feedback information is sent on an HS-SICH channel corresponding to the SCCH. On the Node B side, for each HS-DSCHTTI, for a certain UE, the MAC-hs selects an HS-SCCH for the UE to use, that is, sends the HS-DSCH related control channel to the UE on the HS-SCCH channel. On the UE side, if there is no HS-SCCH allocated to the UE in its HS-SCCH set, the UE will continuously monitor the HS-SCCH set, and compare it with the UE's own identity by reading the "UE ID" information on the HS-SCCH , from which to search for the HS-SCCH that is actually allocated to the UE until an HS-SCCH channel that is allocated to the UE is found. From the next TTI, only the HS-SCCH is monitored and received, and the control information carried by it is used to receive the HS -DSCH data, and send feedback information on an HS-SICH channel corresponding to the HS-SCCH, until at a certain TTI, the UE cannot read the UE identity that matches itself on the HS-SCCH, or cannot read the HS -SCCH, then the UE re-monitors the allocated HS-SCCH set, and it is worth finding an HS-SCCH allocated to the UE.

The above description is about the TD-SCDMA system HSPDA technology in the current 3GPP agreement. However, the TD-SCDMA system in the current 3GPP agreement is a single-carrier system, that is, one cell corresponds to one carrier, and the spectrum width of a single carrier is 1.6M. Since TD-SCDMA uses a relatively narrow-band TDD method, the theoretical peak rate on a single carrier It can reach 2.8Mbps, and the downlink peak rate that can be provided on a single carrier is relatively low, which cannot well meet the needs of operators for future high-speed packet data services. Therefore, it is necessary to make some technical improvements based on the single-carrier cell HSDPA technology to meet the higher requirements of operators for high-speed packet data services.

In the TD-SCDMA multi-carrier HSDPA technology, in addition to the HS-SCCH and HS-SICH physical channels related to the HS-PSDCH, the uplink and downlink accompanying dedicated physical channels are also defined and allocated for carrying RRC signaling messages. However, compared with the single-carrier HSPDA technology of the TD-SCDMA system in the existing 3GPP agreement, because in the TD-SCDMA multi-carrier HSDPA technology, a UE can be allocated physical channel resources on different carriers, resulting in multi-carrier HSDPA The HS-PDSCH physical channel, HS-SCCH and HS-SICH physical channel pair, and the configuration and allocation method of the uplink and downlink accompanying dedicated physical channels in the technology cannot follow the allocation method in the case of single carrier. Therefore, it is necessary to provide a A channel configuration and allocation method suitable for multi-carrier high-speed downlink packet access technology.

Detailed ways

Like the single-carrier HSDPA technology, in the multi-carrier HSDPA technology, the downlink data service is sent through the HS-DSCH transmission channel, and the transmission HS-DSCH is mapped to the HS-PDSCH physical channel, and the HS-PDSCH physical channel allocation and control related Control information is sent on the downlink HS-SCCH physical channel and uplink HS-SICH physical channel, and the channel characteristics of HS-PDSCH, HS-SCCH and HS-SICH physical channels in multi-carrier systems, as well as accompanying dedicated channels, including transport channels Both the characteristics of the physical channel and the single carrier system in the 3GPP agreement are the same.

The system that the present invention is applicable to is: the multi-carrier HSDPA resources of a multi-carrier cell are configured by the RNC, including HS-PDSCH physical channel resources and HS-SCCH and HS-SICH physical channel pair resources, wherein each HS-SCCH physical channel It is fixedly configured as a pair with a certain HS-SICH physical channel of the same carrier. The Node B, that is, a MAC-hs functional entity created in the Node B, manages and allocates these HS-PDSCH physical channel resources, HS-SCCH and HS-SICH physical channel pair resources.

In the multi-carrier HSDPA technology, considering the compatibility with the TD-SCDMA single-carrier HSDPA technology in the existing 3GPP standard, the HS-SCCH and HS-SICH physical channel pairs can only be used to allocate HS-PDSCH physical channel resources on one carrier, That is, slots and code channels. Therefore, channel configuration and allocation in multi-carrier HSDPA technology requires a two-step allocation method, that is, the first step: initial allocation of HSDPA resources, initial allocation of carrier resources for HS-PDSCH physical channels for user terminals, The HS-SCCH and HS-SICH physical channel pair resources associated with the carrier of the HS-PDSCH physical channel, as well as the accompanying dedicated physical channel resources; the second step: the dynamic allocation of HSDPA resources, through the HS-SCCH and HS-SICH physical channel resources The channel pair dynamically allocates HS-PDSCH time slots and code channel resources in real time on the initially allocated carrier.

In HSDPA technology, RNC initially configures HS-SCCH and HS-SICH physical channel resources and HS-PDSCH physical channel resources, but Node B manages and allocates these resources. In addition, RNC is also responsible for managing and allocating uplink and downlink accompanying dedicated physical channels. channel resources.

The invention provides a multi-carrier HSDPA technology in a TD-SCDMA system, RNC initially configures HS-SCCH and HS-SICH physical channel resources and HS-PDSCH physical channel resources, allocates accompanying dedicated physical channel resources, and Node B initially allocates The carrier resources of the HS-PDSCH physical channel and the related HS-SCCH and HS-SICH physical channel methods can solve the problems of channel configuration, management and allocation of RNC and Node in the multi-carrier HSDPA technology.

The present invention provides following five kinds of schemes, the present invention is described:

Option 1 includes the following steps:

1) The RNC initiates the physical shared channel reconfiguration process in the NBAP protocol to the Node B through the Iub interface to realize the configuration of HS-PDSCH physical channel resources and several pairs of HS-SCCH and HS-SICH on one or more carriers of the multi-carrier cell Physical channel pair resource. For each carrier configured with HS-PDSCH physical channel resources, only a few pairs of HS-SCCH and HS-SICH physical channel resources are configured on these carriers, but the number of HS-PDSCH physical channel resources configured on them can be different Different numbers of HS-SCCH and HS-SICH physical channel pair resources are configured, and the configuration rules of the two resources are the same as those in the single-carrier HSDPA technology in the existing 3GPP standard.

As shown in Figure 1A, assuming that there are 6 carriers, HS-PDSCH physical channels are configured on carriers 2, 4, and 6, and HS-SCCH and HS-SICH are configured on each of carriers 2, 4, and 6 Physical channel pairs, wherein carrier 2 is configured with 1 pair, and carriers 4 and 6 are configured with 2 pairs. Wherein, the dotted line box represents configured channels and carriers (except the dedicated channel carrier), and the double-dot dash line box represents the carrier without HSDPA resource allocation.

2) The RNC records the initial configuration information of the HS-PDSCH physical channel resources on each carrier, and records the allocation information of the HS-PDSCH physical channel resources on each carrier in real time. The RNC can record in real time the number of user terminals allocated HS-PDSCH physical channel carrier resources on each carrier according to the information sent by the Node B in step 4, so as to estimate the load situation of the HSDPA resources on the carrier.

Wherein, the allocation information recorded in real time comes from the allocation result shown in FIG. 1C , one UE (user terminal) is allocated on carriers 2 and 6, and two UEs are allocated on carrier 4 .

3) When the RNC determines to allocate HSDPA resources for a certain service of a certain user terminal, the RNC allocates accompanying dedicated physical channel resources for the user terminal on the carrier configured with HS-PDSCH physical channel resources, and assigns the accompanying dedicated physical channel resources to the user terminal. Resource configuration information (including carrier information) is sent to Node B, and Node B is requested to allocate other HSDPA-related resources for the user terminal at the same time. The RNC can initiate the Radio Link Setup (Radio Link Setup) process, the Synchronized Radio Link Reconfiguration Preparation (Synchronized Radio Link Reconfiguration Preparation) process or the Unsynchronized Radio Link Reconfiguration (Unsynchronized Radio Link Reconfiguration) process in the NBAP protocol to the Node B through the Iub interface. ) process to complete this step.

When the RNC allocates the carrier resources of the accompanying dedicated physical channel resources for a certain UE, at least two factors need to be considered: first, the unallocated physical channel resources available on the carrier; , the number of user terminals allocated HS-PDSCH physical channel carrier resources, the RNC can use this to estimate the load of the HSDPA resources on the carrier.

As shown in Figure 1B, choose to allocate dedicated accompanying physical channels for UE1 and UE2 on carrier 2 and carrier 6 respectively (according to the record in step 2, HS-PDSCH, HS-SCCH and HS-SICH can be allocated on carriers 2 and 6 ). In the figure, the solid line boxes represent allocated channels and carriers (except for dedicated channel carriers), the dotted line boxes represent configured channels and carriers (except for dedicated channel carriers), and the double dotted line boxes represent carriers without allocated HSDPA resources.

4) When the Node B initially allocates HSDPA resources for a user terminal, the Node B allocates one or more HS-PDSCH physical channel carrier resources to the user terminal, which must include the carrier where the dedicated physical channel is located. At the same time, for each allocated HS-PDSCH physical channel resource on the carrier, one or more pairs of HS-SCCH and HS-SICH physical channel pairs are allocated on the carrier to be associated with it.

When Node B allocates HS-PDSCH physical channel carrier resources and HS-SCCH and HS-SICH physical channel pair resources, the factors considered may include at least the carrier where the dedicated physical channel is located, the multi-carrier capability information of the user terminal, and service characteristics Information, as well as HS-PDSCH physical channel resources and resource allocation and usage of HS-SCCH and HS-SICH physical channels on each carrier. The first three kinds of information are provided by RNC in the relevant resource request message; while the last kind of information is provided by Node B itself, because Node B is responsible for managing the allocation of these resources.

The Node sends the HS-PDSCH physical channel carrier resources and the resource allocation results of the HS-SCCH and HS-SICH physical channels to the RNC.

As shown in FIG. 1C , it is a schematic diagram of initially allocating HS-PDSCH physical channel carrier resources, SCCH and SICH physical channel pairs, and the relationship between them for the Node B. Node B allocates two HS-PDSCH carrier resources of carrier 2 and carrier 4 to UE1, and at the same time allocates a pair of HS-SCCH and HS-SICH physical channel pairs on carrier 2 and carrier 4 respectively, which are connected to carrier 2 and carrier 4 respectively. associated with the HS-PDSCH carrier resources; Node B allocated two HS-PDSCH carrier resources, carrier 4 and carrier 6, to UE2, and allocated a pair of HS-SCCH and HS-SICH physical resources on carrier 4 and carrier 6 respectively. Channels are associated with the HS-PDSCH carrier resources on carrier 4 and carrier 6 respectively. Wherein, the dotted line box indicates the configured channel, the solid line box indicates the allocated channel, and the dotted double arrow line indicates that the HS-PDSCH physical channel carrier is associated with the SCCH and SICH physical channel pair.

In this way, when the Node B dynamically allocates HS-PDSCH physical channel resources to the UE, the allocation situation is shown in Figure 1D, where the solid line boxes represent the allocated channels and carriers (except dedicated channel carriers), and the dotted line boxes represent the configured channels and carriers. Carriers (except for dedicated channel carriers), the double-dot dash line box indicates a carrier that has not allocated HSDPA resources.

Option 2 includes the following steps:

1) The RNC initiates the physical shared channel reconfiguration process in the NBAP protocol to the Node B through the Iub interface to realize the configuration of HS-PDSCH physical channel resources and several pairs of HS-SCCH and HS-SICH on one or more carriers of the multi-carrier cell Physical channel pair resource. For each carrier configured with HS-PDSCH physical channel resources, only a few pairs of HS-SCCH and HS-SICH physical channel resources are configured on these carriers, but the number of HS-PDSCH physical channel resources configured on them can be different Different numbers of HS-SCCH and HS-SICH physical channel pair resources are configured, and the configuration rules of the two resources are the same as those in the single-carrier HSDPA technology in the existing 3GPP standard.

As shown in Figure 2A, assuming that there are 6 carriers, HS-PDSCH physical channels are configured on carriers 2, 4, and 6, and HS-SCCH and HS-SICH are configured on each of 2, 4, and 6 Physical channel pairs, wherein carrier 2 is configured with 1 pair, and carriers 4 and 6 are configured with 2 pairs.

2) When the RNC determines to allocate HSDPA resources for a certain service of a certain user terminal, the RNC allocates an accompanying dedicated physical channel resource for the user terminal on a suitable carrier among all carriers in the multi-carrier cell, and assigns the accompanying dedicated physical channel resource to the user terminal. The configuration information (including carrier information) of the dedicated physical channel resources of the user terminal is sent to the Node B, and the Node B is requested to allocate other resources related to HSDPA for the user terminal at the same time. The RNC can initiate the Radio Link Setup (Radio Link Setup) process, the Synchronized Radio Link Reconfiguration Preparation (Synchronized Radio Link Reconfiguration Preparation) process or the Unsynchronized Radio Link Reconfiguration (Unsynchronized Radio Link Reconfiguration) process in the NBAP protocol to the Node B through the Iub interface. ) process to complete this step.

When the RNC allocates the carrier resources of the accompanying dedicated physical channel resources for a UE, at least it needs to consider the unallocated physical channel resources available on the carrier.

As shown in FIG. 2B , UE1 and UE2 are selected to allocate dedicated accompanying physical channels on carrier 1 and carrier 5 respectively.

3) When the Node B initially allocates HSDPA resources for a user terminal, the Node B allocates one or more HS-PDSCH physical channel carrier resources to the user terminal, and at the same time, assigns HS-PDSCH physical channel resources on each allocated carrier Channel resources, on which one or more pairs of HS-SCCH and HS-SICH physical channel pairs are allocated to be associated with.

When Node B allocates HS-PDSCH physical channel carrier resources and HS-SCCH and HS-SICH physical channel pair resources, the factors considered may at least include multi-carrier capability information of user terminals, service characteristic information, and HS-PDSCH physical channel resources and resource allocation and usage of HS-SCCH and HS-SICH physical channels. The first two kinds of information are provided by RNC in the relevant resource request message; while the last kind of information is provided by Node B itself, because NodeB is responsible for managing the allocation of these resources.

As shown in Figure 2C, Node B allocates two HS-PDSCH carrier resources of carrier 2 and carrier 4 to UE1, and allocates a pair of HS-SCCH and HS-SICH physical channels on carrier 2 and carrier 4 respectively, respectively The HS-PDSCH carrier resources on carrier 2 and carrier 4 are associated; Node B allocates two HS-PDSCH carrier resources, carrier 4 and carrier 6, to UE2, and allocates a pair of HS-SCCH on carrier 4 and carrier 6 respectively and the HS-SICH physical channel are associated with the HS-PDSCH carrier resources on carrier 4 and carrier 6 respectively.

In this way, when the Node B dynamically allocates HS-PDSCH physical channel resources to the UE, the allocation situation is shown in Figure 2D, where the solid line boxes represent the allocated channels and carriers (except dedicated channel carriers), and the dotted line boxes represent the configured channels and carriers. Carriers (except for dedicated channel carriers), the double-dot dash line box indicates a carrier that has not allocated HSDPA resources.

The Node sends the HS-PDSCH physical channel carrier resources and the resource allocation results of the HS-SCCH and HS-SICH physical channels to the RNC.

When the RNC configures HS-SCCH and HS-SICH physical channel pair resources on one or more carriers of a multi-carrier cell, it can configure a pair of HS-SCCH and HS-SICH physical channel resources only on carriers within the subset of carriers configured with HS-PDSCH physical channel resources. Or multiple pairs of HS-SCCH and HS-SICH physical channel resources; it can also be allocated independently of the carrier where the HS-PDSCH physical channel resources are located;

As shown in Figure 3A, assuming that there are 6 carriers, HS-PDSCH physical channels are configured on carriers 2, 4, and 6, and HS-SCCH and HS-SICH physical channels are configured on each of 2, 4, and 6. Channel pairs, wherein one pair is configured on carrier 2, and two pairs are configured on carriers 4 and 6 respectively.

The RNC can record in real time the number of user terminals allocated HS-PDSCH physical channel carrier resources on each carrier and each pair of HS-SCCH and HS-SICH physical channels on each carrier according to the information sent by the Node B in step 4 For the number of allocated user terminals, it is used to estimate the HSDPA resources on the carrier and the resource load of HS-SCCH and HS-SICH physical channels;

Wherein, the allocation result of the record comes from the allocation result in FIG. 3C , the HS-PDSCH physical channel resources on carriers 2 and 6 are allocated with one UE (user terminal), and the HS-PDSCH physical channel resources on carrier 4 are allocated with Two UEs. The two pairs of HS-SCCH and HS-SICH physical channels on carrier 4 are allocated to one UE respectively, and the two pairs of HS-SCCH and HS-SICH physical channels on carrier 6 are allocated to one UE respectively.

3) When the RNC determines to allocate HSDPA resources for a certain service of a certain user terminal, the RNC allocates accompanying dedicated physical channel resources for the user terminal on the carrier configured with HS-SCCH and HS-SICH physical channel pair resources, and puts The accompanying dedicated physical channel resource configuration information (including carrier information) is sent to the Node B, and at the same time, the Node B is requested to allocate other HSDPA-related resources for the user terminal. The RNC can initiate the Radio Link Setup (Radio Link Setup) process, the Synchronized Radio Link Reconfiguration Preparation (Synchronized Radio Link Reconfiguration Preparation) process or the Unsynchronized Radio Link Reconfiguration (Unsynchronized Radio Link Reconfiguration) process in the NBAP protocol to the Node B through the Iub interface. ) process to complete this step.

When the RNC allocates the carrier resources of the accompanying dedicated physical channel resources for a certain UE, at least three factors can be considered: first, the unallocated physical channel resources available on the carrier; , the number of user terminals allocated HS-PDSCH physical channel carrier resources, the RNC can use this to estimate the load situation of the HS-PDSCH physical channel resources on the carrier; third, on the carrier, each pair of HS-SCCH and HS -The number of user terminals assigned to the SICH physical channel is used to estimate the resource load of the HS-SCCH and HS-SICH physical channels on the carrier;

4) When the Node B initially allocates HSDPA resources for a certain user terminal, the Node B allocates one or more HS-PDSCH physical channel carrier resources to the user terminal, and at the same time, on the carrier where the accompanying dedicated physical channel is located, for each The allocated HS-PDSCH physical channel resources on the carrier are allocated with one or more pairs of HS-SCCH and HS-SICH physical channel resources associated with them.

When Node B allocates HS-PDSCH physical channel carrier resources, it can follow two processes, one is to include the carrier where the accompanying dedicated physical channel is located; the other is to allocate independently of the carrier where the accompanying dedicated physical channel is located.

When Node B allocates HS-PDSCH physical channel carrier resources and HS-SCCH and HS-SICH physical channel pair resources, the factors considered may include at least the carrier where the dedicated physical channel is located, the multi-carrier capability information of the user terminal, and service characteristics Information, as well as HS-PDSCH physical channel resources and resource allocation and usage of HS-SCCH and HS-SICH physical channels on each carrier. The first three kinds of information are provided by RNC in the relevant resource request message; while the last kind of information is provided by Node B itself, because Node B is responsible for managing the allocation of these resources.

The Node sends the HS-PDSCH physical channel carrier resources and the resource allocation results of the HS-SCCH and HS-SICH physical channels to the RNC.

Wherein, the allocation result of the record comes from the allocation result in FIG. 4C, the HS-PDSCH physical channel resources on carriers 2 and 6 are allocated with one UE (user terminal), and the HS-PDSCH physical channel resources on carrier 4 are allocated with Two UEs. A pair of HS-SCCH and HS-SICH physical channels on carrier 2 is allocated to one UE, two pairs of HS-SCCH and HS-SICH physical channels on carrier 4 are allocated to one UE respectively, and two pairs of HS on carrier 6 - SCCH and HS-SICH physical channel pairs are allocated to one UE respectively.

3) When the RNC determines to allocate HSDPA resources for a certain service of a certain user terminal, the RNC allocates accompanying dedicated physical channel resources for the user terminal on the carrier configured with HS-SCCH and HS-SICH physical channel pair resources, and puts The accompanying dedicated physical channel resource configuration information (including carrier information) is sent to the Node B, and at the same time, the Node B is requested to allocate other HSDPA-related resources for the user terminal. The RNC can initiate the Radio Link Setup (Radio Link Setup) process, the Synchronized Radio Link Reconfiguration Preparation (Synchronized Radio Link Reconfiguration Preparation) process or the Unsynchronized Radio Link Reconfiguration (Unsynchronized Radio Link) process in the NB AP protocol to the Node B through the Iub interface.

4) When the Node B initially allocates HSDPA resources for a user terminal, the Node B allocates one or more HS-PDSCH physical channel carrier resources to the user terminal, and at the same time, on one or more carriers, it must include the accompanying For the carrier where the dedicated physical channel is located, assign one or more pairs of HS-SCCH and HS-SICH physical channel pairs to associate with the HS-PDSCH physical channel resource on each allocated carrier;

When Node B allocates HS-PDSCH physical channel carrier resources, it can follow two processes, one is to include the carrier where the accompanying dedicated physical channel is located; the other is to allocate independently of the carrier where the accompanying dedicated physical channel is located.

When Node B allocates HS-PDSCH physical channel carrier resources and HS-SCCH and HS-SICH physical channel pair resources, the factors considered may include at least the carrier where the dedicated physical channel is located, the multi-carrier capability information of the user terminal, and service characteristics Information, as well as HS-PDSCH physical channel resources and resource allocation and usage of HS-SCCH and HS-SICH physical channels on each carrier. The first three kinds of information are provided by RNC in the relevant resource request message; while the last kind of information is provided by Node B itself, because Node B is responsible for managing the allocation of these resources.

The Node sends the HS-PDSCH physical channel carrier resources and the resource allocation results of the HS-SCCH and HS-SICH physical channels to the RNC.

As shown in Figure 4C, Node B allocates two HS-PDSCH carrier resources of carrier 2 and carrier 4 to UE1, and at the same time allocates two pairs of HS-SCCH and HS-SICH physical channel pairs on carrier 2 and carrier 4, respectively The HS-PDSCH carrier resources on carrier 2 and carrier 4 are associated; Node B allocates three HS-PDSCH carrier resources of carrier 2, carrier 4 and carrier 6 to UE2, and allocates three pairs of HS on carrier 2 and carrier 6 - SCCH and HS-SICH physical channel pairs, associated with HS-PDSCH carrier resources on carrier 2, carrier 4 and carrier 6 respectively.

In this way, when the Node B dynamically allocates HS-PDSCH physical channel resources to the UE, the allocation situation is shown in Figure 5D, where the solid line boxes represent the allocated channels and carriers (except dedicated channel carriers), and the dotted line boxes represent the configured channels and carriers. Carriers (except for dedicated channel carriers), the double-dot dash line box indicates a carrier that has not allocated HSDPA resources.

After the steps in the above-mentioned various schemes are completed, the RNC initially allocates the Node B to the user terminal and sends to the RNC the HS-PDSCH physical channel carrier resource and its associated HS-SCCH and HS-SICH physical channel pair resources, and The associated dedicated physical channel resources are sent to the user terminal through the relevant procedures of the RRC protocol of the Uu interface.
