Method and device for determining E-DCH physical channel timing of SHO state transition UE

technical field

The present invention relates to WCDMA uplink dedicated channel enhancement, in particular to how to determine the timing relationship of the UE-related E-DCH physical channel when the UE performs SHO state transition in the E-DCH (uplink dedicated channel enhancement) service. method.

Background technique

As the importance of IP-based data services increases, it is increasingly necessary to define a new enhanced uplink data transmission, which can improve system coverage and throughput while reducing the time delay of uplink data services. E-DCH transmission emerges at the historic moment under such circumstances. It is used in urban, suburban and rural areas to support mobile environments, but it has the best performance in low-speed and medium-speed environments. The capacity of the system needs to be significantly improved if the complexity allows, which is the standard for evaluating E-DCH transmission, and at the same time, the complexity of the UE and the network needs to be reduced as much as possible under the given system performance conditions. The impact on the current 3GPP standard specification needs to be considered from the perspective of protocol and hardware.

E-DCH is a technology researched by 3GPP in order to use cell uplink power resources more effectively, improve cell uplink throughput and uplink data transmission rate, and provide larger cell coverage. Compared with the scheduling of RNC (radio network controller), the fast scheduling of uplink resources by Node B (base station) can better solve the problem of limited uplink channel interference. In the existing Rel99/Rel4/Rel5 specifications, both the scheduling of uplink resources and the data transmission rate are controlled by the RNC. For changes in the uplink load, the RNC does not respond as quickly as the Node B, so the Node B has a greater advantage in scheduling uplink resources for E-DCH transmission.

In the prior art, the timing relationship of each related physical channel of a DPCH (Dedicated Physical Channel) of a UE (mobile terminal) is shown in FIG. 1 . The sending time of the UE's downlink DPCH is an integer multiple of 256 chips after the P-CCPCH channel frame boundary. For example, the time offset of the UE's downlink DPCH transmission moment relative to the P-CCPCH channel frame boundary is defined as τ _{DPCH, n} = T _n × 256chip, T _n ∈ {0, 1, ..., 149}, the same cell The T _n parameters obtained by different UEs are different, and are determined by corresponding high-level signaling parameters. The sending time of the UE uplink DPCH is T ₀ (1024 chips) after receiving the first path of the corresponding downlink DPCH frame.

There are two basic ways how to transmit the E-DCH of the UE in the existing system: code division multiplexing and time division multiplexing. Code division multiplexing means that the E-DCHs of multiple UEs can be transmitted in parallel, as long as the interference caused does not exceed the interference threshold of the Node B. Because uplink resources (such as power) are limited, time division multiplexing theoretically allows only some UEs to transmit E-DCH at the same time. Of course, this does not exclude the use of scheduling methods other than these two methods, such as a mixed method of these two methods.

But when the UE is in the SHO state, because one or more Node Bs schedule the E-DCH service of the UE, not all Node Bs can know the information about the scheduling resources and timing relationship of the UE. For some Node Bs in the Active set, if the timing (timing relationship) of the E-DCH related physical channel of the UE cannot be determined, correct reception will be affected. No matter what multiplexing method is used for the E-DCH-related physical channels of the UE, this problem always exists in the SHO area. As shown in Figure 2, Node B I and II both schedule the UE, but Node BI is the timing reference Node B (timing reference Node B) of the UE, while Node B II is not. Then, Node B II cannot accurately know the timing (timing) of the E-DCH channel of the UE without the relevant signaling (signaling) notification from the CRNC (control type radio network controller), thus affecting the correct reception .

In the SHO area, one or more Node Bs participate in scheduling the E-DCH channel of the UE. No matter which rule the UE follows for E-DCH transmission, it cannot be guaranteed that all Node Bs in the Active set know about The scheduling information and timing relationship related to the UE E-DCH channel.

Therefore, how to make the timing of the E-DCH performed by the UE in the SHO area known to the Node B in the Activeset becomes a problem that must be solved.

Contents of the invention

In view of the above existing problems, the object of the present invention is to provide UE E-DCH transmission for SHO state, and propose a method for Node B in the Active set to determine the timing of the relevant E-DCH physical channel.

In order to achieve the above object, a method for determining the timing of the E-DCH physical channel of the SHO state transition UE, comprising steps:

Define the time offset τDPCH,n of the UE's downlink DPCH transmission moment relative to the P-CCPCH channel frame boundary;

The SRNC determines the timing relationship between the E-DCH channel and the UL DPCH channel after considering the time offset τDPCH, n information;

The SRNC transmits the E-DCH timing offset parameter to the UE through RRC signaling when establishing or reconfiguring the Radio Link, so that the timing of the E-DCH TTI of different UEs in the same cell is aligned;

When the UE enters the SHO area, the CRNC notifies the timing relationship to each Node B in the Active Set through Iub signaling.

The method provided by the present invention does not change the timing (timing) of other relevant channels of the existing system, but provides for the timing (timing) of the E-DCH channel, and increases the Iub interface signaling from CRNC to Node B Corresponding timing (timing) parameters, so compatible with WCDMARel99/4/5 system.

Description of drawings

Figure 1 is a schematic diagram of the timing relationship between P-CCPCH, uplink DPCH, and downlink DPCH in the Rel99 system; in the figure, the sending time of the downlink DPCH of 101 UEs is an integer multiple of 256 chips after the P-CCPCH channel, and the sending time of the UE's downlink DPCH is relative to The time offset of the P-CCPCH channel is defined as τ _{DPCH, n} = T _n × 256chip, T _n ∈ {0, 1, ..., 149}, T _n parameters obtained by different UEs in the same cell are different , indicated by the corresponding high-level signaling parameters; 102 indicates that the sending moment of the UE uplink DPCH is at T ₀ (1024chip) after receiving the first path of the corresponding downlink DPCH frame. In this way, the timing (timing) of the DL DPCH and the UL DPCH is directly or indirectly determined using the P-CCPCH channel as a time reference.

Figure 2 is an example of Node B scheduling UE E-DCH transmission in the SHO area; UE (205) receives the scheduling instructions of Node B-I (203) and Node B-II (204) when SHO, wherein 203 is timingreference Node B; RNC Communicate with the Node B in the Active set, if the CRNC to which the Node B belongs is the SRNC to which the UE belongs, as shown in Figure 203 for NodeB-I, then the SRNC directly assigns the Node B-I (203) through the Iub interface signaling EDCH timing parameters; if the CRNC to which the Node B belongs is not the SRNC to which the UE belongs, as shown in Figure 204, the CRNC of NodeB-II (204) is a DRNC (Drift RNC, i.e. a radio network controller of drift type), so the SRNC ( 201) carry out Iur interface communication with CRNC (202), the timing parameter relevant to EDCH is delivered from SRNC to DRNC, then by the CRNC of NodeB-II that is the DRNC (202) of UE to this Node B-II (204) Transmit EDCH timing parameters through Iub interface signaling, so as to ensure that NodeB-II in SHO state can accurately receive EDCH-related physical channels from UE

Figure 3 is a schematic diagram of SHO E-DCH timing (timing); in the figure, the sending time of UE1's downlink DPCH channel (301) is an integer (Tn1) times chips of 256 after the P-CCPCH channel, and the sending time of UE1's downlink DPCH is relatively The time offset of the P-CCPCH channel is defined as τ _{DPCH, n1} = T _n1 × 256chip, T _n ∈ {0, 1, ..., 149}, T _n parameters obtained by different UEs in the same cell are different , and is determined by high-level signaling parameters; UE1's uplink DPCH (302) is sent at T ₀ (1024chip) after receiving the first path of the corresponding downlink DPCH frame. In this way, the timings of the DL DPCH and the UL DPCH of UE1 are directly or indirectly determined by the P-CCPCH channel as a time reference. All of the above are the same as those shown in Figure 1, and no changes have been made to the existing WCDMA R99/R4/R5 system. The newly added definition specifies that the timing of the E-DCH is at t*256chip behind the UL DPCH, where t∈{0, 1,...,149}, as shown in the figure, the E-DCH of UE1 The channel (303) transmission timing (timing) is at t1*256chip behind the UL DPCH, where t1∈{0, 1, ..., 149}, as shown in 306, the E-DCH transmission timing of UE2 is on the UL DPCH At t2*256chip later, where t2∈{0, 1, . . . , 149}; in this way, the timing of the E-DCH can be determined according to the timing of the UL DPCH. A similar situation exists for UE2 in FIG. 3 . In addition, it needs to be pointed out that the t values obtained by different UEs in the same Node B should meet the conditions: the timing (timing) can be aligned between the UL E-DCH TTIs of different UEs, and the TTI parts of the transmission do not overlap ; Only in this way can the increase of ROT in this community be effectively controlled.

Figure 4 is a schematic diagram of adding E-DCH timing offset parameters in NBAP information. When the UE enters the SHO area, the corresponding Node B will be added to the active set (Active set) and a radiolink connection will be established with the UE. In the NBAP signaling that the SRNC or DRNC notifies the newly joined Node B to establish a connection with the UE radio link, a corresponding message needs to be added to notify the newly joined Node B to obtain the timing of the corresponding UE E-DCH service, which is beneficial Correct reception of the UE E-DCH by the Node B. The added E-DCH timing offset parameter can be added to the FDD Iub interface message of Radio link setuprequest, as shown in the figure E-DCH timing offset (401), this parameter is also the t described above. Since t∈{0, 1, . . . , 149}, only 8 bits are required, and the added parameter does not change the transmission of other signaling parameters.

If the UE is in the SHO state transition, and the CRNC belonging to the NodeB that needs to establish a radio link (Radio Link) in its active set is not the SRNC of the UE, then the SRNC to which the UE belongs needs to signal RNSAP to the DRNC to which the NodeB belongs through the Iur interface The EDCH-related timing parameter E-DCH timing offset (501) of the UE is transmitted, which is similar to the description of the NBAP signaling process above, and this parameter is also the t described above. Since t∈{0, 1, . . . , 149}, only 8 bits are required, and adding this parameter does not change the transmission of other signaling parameters.

Figure 5 is an example of adding the E-DCH timing offset parameter in the RNSAP information.

Figure 6 is a flowchart of Node B receiving UE E-DCH in Active set in SHO area. In step 602, the SRNC determines the UE uplink E-DCH timing offset parameter; then in step 603, the E-DCH timing offset parameter is notified to the UE through RRC signaling, and the UE transmits the E-DCH at the corresponding timing according to the obtained parameter ; and when the UE performs SHO conversion, it will update the Node B in the Active set; CRNC will notify the corresponding Node B about receiving the E-DCH timing offset parameter in the signaling of Radio link setup or Radio link reconfiguration -timing of the DCH, step 604 completes this function; then, step 605 enables the Node B in the Active set to receive the E-DCH at the corresponding time according to the timing information notified by the CRNC. This is also the process of how the Node B in the active set of the SHO area receives the UE E-DCH in the present invention.

Detailed ways

Aiming at the E-DCH transmission technology in the WCDMA system, the present invention proposes a method for how the Node B in the UE activation concentration obtains the timing relationship of the E-DCH physical channel of the UE when the UE performs SHO state transition.

The present invention proposes: as long as the E-DCH has a definite timing relationship with the UL DPCH channel, and the system can notify the timing relationship to each Node B in the Active Set, then the corresponding Node B can also receive the UL DPCH while receiving the UL DPCH. Can accurately receive the corresponding E-DCH channel.

In the first part, as shown in Figure 3, the time offset of the UE’s downlink DPCH transmission moment relative to the P-CCPCH channel frame boundary is defined as τ _{DPCH, n} = T _n × 256chip, T _n ∈ {0, 1, . .., 149}, the T _n parameter obtained by each UE is different, and this parameter is transmitted through high-layer signaling. The sending time of the UE uplink DPCH is after receiving T ₀ (1024chip) time of the first path of the corresponding downlink DPCH frame. The above content is the same as the existing system, without making any changes to the existing system. Different from the existing system, the present invention proposes that the timing of the E-DCH channel is at t*256chip after the transmission time of the UL DPCH channel, t∈{0, 1, . . . , 149}. Among them, the t parameter allocated by SRNC is different for different UEs, and this parameter is transmitted by high-level signaling; the t values obtained by different UEs in the same Node B should meet the condition: the UL E-DCH TTI of different UEs The timing between them can be aligned, and the TTI part of the transmission does not overlap. Fig. 6 shows that according to this solution, the UE uses the E-DCH timing calculation module and the control module to control the transmission of the UE uplink E-DCH channel according to a given timing requirement.

In the second part, when the UE enters the SHO area, it cannot be guaranteed that all NodeBs in the UE's Active set can understand the UE's E-DCH timing; and the Node B in the Active set needs to accurately receive the UE's E-DCH, it first needs to Know the timing of the UE's E-DCH channel, that is, the t value described in the first part above. The t parameter can be added to the Active set by the Node B, and when a new radio link (Radio Link) needs to be established for the UE, the CRNC will add the t parameter to the Radio Link Set Up Request Message of the Iub interface signaling , passed to Node B in the Active set. Since t ∈ {0, 1, ..., 149}, 8 bits are needed to transmit this parameter. When the CRNC transmits the t parameter to the Node B in the Active set through the Iub interface signaling, the Node B can obtain the accurate timing of the E-DCH channel of the corresponding UE, thereby accurately receiving the E-DCH. As shown in Figure 8, 803 obtains the UE's E-DCH channel uplink sending Timingoffset parameter from the CRNC through the Iub interface signaling, and 804 calculates the timing at which the NodeB side receives the UE's uplink E-DCH, so when the receiving time arrives, 804 controls the module 805 to open and start to receive the E-DCH control channel E-DPCCH, and 804 controls 806 to open and start to receive the E-DCH data channel E-DPDCH information. When the UE leaves the SHO area or needs to reconfigure the Radio Link with each Node B in the Active set, since the Reference Timing Node B may have changed, the SRNC needs to notify the UE of the new E-DCH timing offset parameter through RRC signaling. At the same time, CRNC is required to notify each Node B in the active set of the new E-DCH timing offset parameter through Iub signaling.

201 SRNC communicates with Node B I in the Active set, and the CRNC to which Node B I belongs is the SRNC;

202 The CRNC to which Node B II belongs is different from the SRNC, and an interface between the SRNC and the CRNC is needed to exchange information;

203 Node B I schedules the E-DCH service of the UE, not only receiving uplink E-DCH data, but also interacting with the UE on E-DCH service signaling;

204 Node B II also schedules the E-DCH service of the UE, not only receiving uplink E-DCH data, but also interacting with the UE on E-DCH service signaling;

205 UE only accepts the scheduling of multiple Node Bs during SHO, and sends E-DCH channel.

302 UE1 sends the uplink DPCH at T ₀ (1024 chips) after receiving the first path of the corresponding downlink DPCH frame. In this way, the timing of UL DPCH and DL DPCH can be determined directly or indirectly by using the P-CCPCH channel as a time reference point;

306 The timing of the E-DCH of UE2 is at t2*256chip behind the UL DPCH, where t2∈{0, 1,...,149}; in this way, the timing of the E-DCH can be determined according to the timing of the UL DPCH. Among them, the t1 and t2 values obtained by UE1 and UE2 respectively should meet the condition: the timing can be aligned between the UL E-DCH TTIs of different UEs, and the transmitted TTI parts do not overlap.

Figure 4 describes an example of adding the E-DCH timing offset parameter in the NBAP information. 401 In the NBAP signaling that the CRNC informs the Node B that it needs to establish a radio link connection with the UE, a corresponding message needs to be added to notify the Node B to obtain the corresponding UE E - Timing of the DCH service, which is conducive to the correct reception of the UE E-DCH by the Node B. The added E-DCH timing offset parameter can be added to the FDD message of Radio link setup request, as shown in 401 in the figure, and this parameter is also the t described above. Since t∈{0, 1, ..., 149}, only 8 bits are needed;

Figure 5 describes an example of adding the E-DCH timing offset parameter in the RNSAP information. 501 In the RNSAP signaling that the SRNC informs the DRNC that it needs to establish a radio link connection, a corresponding message needs to be added to notify the DRNC to obtain the corresponding UE E-DCH service Timing, which is beneficial for DRNC to control the correct reception of the UE E-DCH by the Node B. The added E-DCH timing offset parameter can be added to the FDD RNSAP message of Radio link setup request, as shown in 501 in the figure, and this parameter is also the t described above.
