An important feature of the third generation mobile communication system is the unbalanced traffic on the service and the downlink. The traffic volume on the downlink is generally larger than the traffic on the uplink. In response to this demand, 3GPP (3rd Generation Partnership Project) introduced the High Speed Downlink Packet Access (HSDPA) feature in the third generation mobile communication (3G) specification. In the HSDPA feature, by introducing Adaptive Modulation and Coding (AMC), hybrid automatic repeat request (HARQ: Hybrid) to provide higher rate downlink packet service rate, improve spectrum utilization efficiency. When R4 is shared with HSDPA When the carrier is networked, the downlink channel is particularly insufficient.

The HS-PDSCH is used to carry the service data of the user, and the HS-PDSCH code resource used by each user in different Transmission Time Intervals is indicated by the NodeB on the HS-SCCH.

HSDPA technology can significantly increase the data transmission rate, which can greatly meet the needs of users for multimedia, high-speed mobile communication services. For HSDPA services, the peak rate of single carrier frequency of TD-SCDMA can reach 2.8 Mbps. In the increasingly mature commercial networks, high-speed HSDPA services become more and more important, and the use of carrier frequency resources becomes more and more necessary. When single carrier frequency When the data traffic reaches the peak rate, the downlink HS-PDSCH needs to occupy 5 slots, then the downlink control channel HS-SCCH needs to be configured to slot 0 (TS0) or the traffic channel needs to be carried in slot 0, or the existing channel The R4 service is transferred to slot 0 for bearer. For a commercial terminal, if the terminal cannot support the time slot 0 bearer channel, the control channel or the traffic channel is carried in the time slot 0, and a collision between the neighboring area measurement and the received downlink data or the control information occurs.

BRIEF abstract

1 is a flow chart of a Node B method for determining allocation of HSDPA resources according to the present invention.

Preferred embodiment of the invention

The core idea of the present invention is that the terminal reports the time slot 0 (TS0) bearer channel capability to the network side, and the network side allocates downlink resources to the terminal according to the time slot 0 bearer channel capability of the terminal.

The present invention will be described below by taking HSDPA resource allocation as an example, but the present invention is not limited thereto. The present invention provides a downlink resource allocation method, including:

Step S1: The terminal (UE) reports the time slot 0 bearer channel capability to the network side;

The time slot 0 bearer channel capability refers to whether the terminal supports the bearer channel in the time slot 0, and the uplink channel notifies the system side that the bearer capability of the TS0 has multiple modes, such as the terminal capability reporting mode, the RRC (radio resource control) connection mode, and the like. .

In the present invention, the time slot 0 bearer channel capability indication field is added to the uplink message to indicate the time slot 0 bearer channel capability of the terminal, and the terminal reports the time slot 0 bearer by using the time slot 0 bearer channel capability indication field in the uplink message. Channel capability. The specific indication method is not limited. For example, when the terminal fills in the indication field, it indicates that the terminal supports the time slot 0 bearer channel, and when the terminal does not fill in the indication field, it indicates that the terminal does not support the time slot 0 bearer channel; or, the indication field is one. When the value is specified, it indicates that the terminal supports the time slot 0 bearer channel. When the indication field is another specified value, it indicates that the terminal does not support the time slot 0 bearer channel.

The network side receives the uplink message sent by the terminal, and acquires the time slot 0 bearer channel capability of the terminal from the time slot 0 bearer channel capability indication field in the uplink message. When the uplink message sent by the terminal does not include the time slot 0 bearer channel capability indication field, the network side considers that the terminal does not support the slot 0 bearer channel.

The uplink message may be a terminal capability report message, an RRC connection setup request message, an RRC connection setup complete message, or a cell update message.

Step S2: The network side allocates downlink resources to the terminal according to the time slot 0 carrying channel capability reported by the terminal. a source, where, if the UE supports the time slot 0 bearer channel, the network side allocates downlink resources configured on the time slot 0 or the non-slot 0 to the UE; if the UE does not support the time slot 0 bearer channel, the network side cannot allocate the time slot. The downlink resource configured on the 0 is allocated to the UE, that is, the network side allocates the downlink resource configured in the non-slot 0 to the UE.

The downlink resources include channel resources such as CS12.2k, CS64k, and PS64k, and HSDPA downlink control channel, HSDPA downlink traffic channel, FPACH (fast access indicator channel), HSUPA downlink control channel, and HSDPA/HSUPA downlink companion channel. .

For a terminal that does not support the slot 0 bearer channel, the control channel or the traffic channel on the slot 0 cannot be allocated to the terminal. For example, even if the terminal with the HSDSCH capability is 15 and the downlink HSDSCH resource of the 5 slots on the network side, If the terminal does not support slot 0 carrying the HSDPA channel, it cannot allocate the HSDSCH resources of the terminal 5 slots. For a terminal that does not support the time slot 0 carrying the downlink channel, if there is no downlink resource that is not slot 0, the downlink resource allocation fails.

For the terminal that supports the time slot 0 bearer channel, the network side allocates the downlink resource according to the algorithm implementation, and may allocate the downlink resource of the time slot 0 to the terminal, or allocate the downlink resource of the non-slot 0 to the terminal.

The network side further includes an RNC (Radio Network Controller) and a Node B (Base Station). The RNC receives the time slot 0 bearer channel capability reported by the terminal, and sends the time slot 0 bearer channel capability of the terminal to the Node B. The Node B allocates downlink resources to the terminal according to the time slot 0 bearer channel capability of the terminal. The indication information is added to the message of the Iub interface (the interface between the RNC and the NodeB), and is used by the RNC to notify the Node B terminal whether the TS0 bearer channel is supported.

The network side allocates downlink resources to the terminal further includes:

The radio network controller acquires the time slot 0 bearer channel capability reported by the terminal from the radio resource control connection setup complete message, and brings the time slot 0 bearer channel capability of the terminal to the base station by using a radio link setup message or a radio link reconfiguration preparation message. ;

After receiving the radio link setup message or the radio link reconfiguration preparation message of the radio network controller, the base station allocates the downlink control channel that the terminal needs to monitor according to the time slot 0 of the terminal, and transmits the allocated downlink control channel information to the radio. The link setup response message or the radio link reconfiguration preparation completion message is sent to the radio network controller; the base station further carries the bearer according to the slot 0 of the terminal. The channel capability allocates a downlink traffic channel to the terminal;

Taking HSDPA resource allocation as an example, the process of allocating HSDPA resources by RNC (Radio Network Controller) includes:

A1) adding a slot 0 bearer capability indication field of the terminal in the RRC connection setup complete message, the terminal carrying the indication field in the RRC connection setup complete message indicating that the terminal supports the slot 0 bearer channel, for example, supporting the control channel or the service channel is established. On the time slot 0, if the indication field is not carried, the network side considers that the terminal does not support the time slot 0 bearer channel. For example, the existing inventory terminal (that is, the terminal used in the network) does not fill in the field, and the network side considers that The stock terminal cannot support the slot 0 bearer channel.

A2) After receiving the RRC Connection Complete message, the RNC saves the time slot 0 of the terminal to bear the channel capability.

A3) When the service is established, the RNC sends the time slot 0 support bearer channel capability of the terminal to the Node B through the radio link setup message or the radio link reconfiguration preparation message, and the Lb interface message needs to be added with the indication information to notify the Node B terminal. There is no TS0 bearer channel capability.

A4) After receiving the radio link setup message or the radio link reconfiguration preparation message of the RNC, the Node B allocates a control channel for the HSDPA service to the terminal according to the time slot 0 bearer capability of the terminal, and sends a radio link setup response message or wireless. The link reconfiguration preparation completion message is sent to the RNC.

A5) The RNC passes the control channel of the HSDPA service that the Node B needs to monitor by the terminal through an RB (Radio Bearer) setup message, an RB reconfiguration message, a physical channel reconfiguration message, an RB release message, a transport channel reconfiguration message, or a cell update message. Configured to the terminal.

The process of the Node B performing the HSDPA resource allocation decision includes:

After the Node B receives the radio link setup message or the radio link reconfiguration preparation message of the RNC, the Node B saves the time slot 0 bearer channel capability information of the terminal carried in the radio link setup or the radio link reconfiguration preparation message. .

B2) When the terminal allocates the HSDPA service control channel, the Node B needs to allocate the control channel set of the HSDPA that the terminal needs to monitor according to the terminal's bearer channel capability in the slot 0. For unsupported The terminal that carries the channel capability of the slot 0, that is, the terminal that does not support the service bearer in the time slot 0, the Node B cannot allocate the control channel configured on the time slot 0 to the terminal; for the terminal that supports the time slot 0 bearer channel capability, that is, the support service The terminal carried in slot 0, the Node B is allocated to the control channel set of the HSDPA service of the terminal according to the algorithm, and the Node B can allocate the control channel configured on the slot 0 or the control configured on the non-slot 0. The channel is given to the terminal.

When the HSDPA service shared channel is allocated to the terminal, the terminal that does not support the time slot 0 bearer capability, that is, the terminal that does not support the service bearer in the time slot 0, cannot allocate the HS-DSCH service channel configured on the time slot 0; For a terminal that supports the slot 0 bearer channel capability, that is, a terminal that supports the service bearer at slot 0, the Node B allocates a time slot allocated to the terminal HS-DSCH according to an algorithm decision, and the Node B can allocate the HS configured on the slot 0. The -DSCH channel may also allocate an HS-DSCH channel configured on non-slot 0 to carry downlink data transmission.

B3) The Node B notifies the RNC of the control channel information of the allocated HSDPA through the radio link setup response message or the radio link reconfiguration preparation completion message.

The invention is further illustrated by a specific embodiment.

In this embodiment, the HS-DSCH channel is configured by using the secondary frequency point slot 0 as an example to describe a protocol standard message interaction process in which the network side allocates HSDPA resources to the terminal supporting the time slot 0 bearer channel capability, as shown in FIG. 1 , including:

Step 101: The RNC receives the RRC connection setup complete message sent by the terminal, and obtains the time slot 0 bearer channel capability of the terminal from the time slot 0 bearer channel capability indication field in the message. In this embodiment, the terminal supports the time slot 0 bearer channel capability. .

Step 102: The RNC brings the terminal support slot 0 bearer channel capability information to the Node B through a radio link reconfiguration preparation message or a radio link setup message.

Step 103: The Node B saves the terminal support slot 0 bearer channel capability information, and allocates a HSDPA control channel to the terminal, and then returns a radio link reconfiguration preparation completion message or a radio link setup response message to the RNC.

Step 104: The RNC sends an RB establishment, an RB reconfiguration, an RB release, a physical shared channel reconfiguration, or a transport channel reconfiguration message to the terminal, and carries the HSDPA service control channel to be monitored and the slot information of the HS-DSCH. Step 105: After receiving the RB establishment (RB reconfiguration, RB release, physical shared channel reconfiguration, transport channel reconfiguration, etc.) message, the terminal sends the RB establishment complete message to the RNC, and then listens to all the configuration sets. The control channel performs data reception on the HS-DSCH according to the indication of the control channel.

In step 106, the Node B allocates the HS-DSCH resource according to the scheduling algorithm. For the terminal that does not support the service bearer in the time slot 0, the Node B cannot allocate the HS-DSCH service channel configured on the time slot 0. The terminal of slot 0, Node B determines the time slot allocated to the terminal HS-DSCH according to the algorithm decision, and the Node B can allocate the HS-DSCH channel configured in slot 0 or the HSD configured in non-slot 0. The SCH channel carries the downlink data transmission.

The network side is configured to receive an uplink message sent by the terminal, and acquire a time slot 0 bearer channel capability of the terminal according to the time slot 0 bearer channel capability indication field in the uplink message; if the uplink message does not carry the The time slot 0 carries the channel capability indication field, and the network side considers that the terminal does not support the time slot 0 bearer channel. The uplink message received by the network side is a terminal capability report message, a radio resource control connection setup request message, a radio resource control connection setup complete message, or a cell update message.

The network side includes a radio network controller and a base station, where:

Further, the radio network controller is configured to acquire a time slot 0 bearer channel capability reported by the terminal from the radio resource control connection setup complete message, and establish a message through the radio link or The radio link reconfiguration preparation message brings the time slot 0 bearer channel capability of the terminal to the base station;

The base station is configured to: after receiving the radio link setup message or the radio link reconfiguration preparation message of the radio network controller, allocate the downlink control channel that the terminal needs to monitor according to the time slot 0 bearer channel capability of the terminal, and allocate the The downlink control channel information is sent to the radio network controller by using a radio link setup response message or a radio link reconfiguration preparation completion message; the base station further allocates a downlink traffic channel to the terminal according to the slot 0 carrier channel capability of the terminal;

In summary, the downlink resource allocation method and system according to the present invention, the network side can perform resource allocation according to different terminal bearer channel capacity of the time slot 0, and does not allocate the terminal that does not support the time slot 0 bearer channel capability. The downlink resource of slot 0 prevents the network side from forcibly allocating resources on slot 0 for the terminal that does not support the slot 0 bearer channel, and the terminal cannot complete the measurement conflict while receiving the data.

One of ordinary skill in the art will appreciate that all or a portion of the steps above may be accomplished by a program to instruct the associated hardware, such as a read-only memory, a magnetic disk, or an optical disk. Alternatively, all or part of the steps of the above embodiments may also be implemented using one or more integrated circuits. Correspondingly, each module/unit in the above embodiment may be implemented in the form of hardware or in the form of a software function module. The invention is not limited to any specific form of combination of hardware and software.

Industrial Applicability The downlink resource allocation method and system provided by the present invention enable the network side to allocate downlink resources according to the TS0 bearer channel capability of the terminal, and solve the problem that the time slot 0 is allocated to the terminal that cannot handle the time slot 0 bearer service. The terminal receives data conflicts caused by the downlink service, and has little impact on the resource allocation process and is simple to implement.
