The present invention relates to the field of wireless communications, and in particular, to a method and system for configuring high speed uplink packet access (HSUPA) physical resources. Background technique

After the introduction of HSUPA in the Time Division-Synchronous Code Division Multiple Access (TD-SCDM A) system, the throughput of the uplink and downlink data services can be further improved, and the 16QAM modulation mode enables the single carrier limit throughput. It reaches 2.2M bit/s. However, with the rapid development of data services, the increasing application of uplink data services, and the introduction of multi-carrier bundled HSDPA technology, the demand for HSUPA multi-carrier bundling technology has been greatly promoted.

Multi-carrier frequency HSUPA technology requires the terminal to simultaneously transmit uplink service data on multiple carriers. Considering the simplicity and compatibility of implementation, the enhanced uplink physical channel of HSUPA

(E-PUCH) needs to be configured on multiple carriers, and one or more enhanced uplink absolute grant channels (E-AGCH) and enhanced uplink HARQ response indicator channels are simultaneously allocated on multiple carriers.

(E-HICH), causing the E-AGCH and E-HICH physical channels on the same carrier to be associated with the E-PUCH physical channel resources on the same carrier. The authorization on each carrier is performed independently. The NodeB dynamically grants the E-PUCH physical resources on the associated co-carriers to the terminal through the E-AGCH on each carrier. The terminal simultaneously uplinks through the authorized E-PUCH physical resources on each carrier. The transmission of data, thereby achieving a substantial increase in uplink data throughput. And the terminal feeds back ACK/NACK information through an E-HICH physical channel on the same carrier associated with the E-AGCH.

For terminals that can support multi-carrier HSUPA bundling, you need to know that multiple carriers are simultaneously on Configuration information of HSUPA physical resources for data transmission. Considering the complexity of the actual network, it is necessary to meet different configuration requirements of the HSUPA carrier frequency, and configure HSUPA physical channel information of multiple frequency points to the terminal. However, the configuration of the HSUPA physical resource in the Radio Resource Control (RRC) message implemented in the current protocol is only a single carrier, which can only satisfy the same configuration of all HSUPA carrier frequencies, but cannot meet the HSUPA carrier frequency configuration.

The basic idea of the present invention is: when the HSUPA carrier frequency configuration is different, the network side sends the HSUPA physical resource configuration information of the plurality of (at least one) frequency points to the terminal by using the RRC message, and the terminal configures according to the received RRC message. HSUPA physical resources at each frequency.

In the present invention, the RRC message carrying the HSUPA physical resource configuration information of multiple frequency points may be a newly added RRC message, or may be an extended existing RRC message.

Preferably, the HSUPA physical resource configuration of the frequency point is not explicitly configured in the RRC message, and the network side may notify the UE of the HSUPA physical resource configuration of the frequency point to be the same as a certain frequency point in an RRC message, for example. If a certain type of HSUPA physical resource configuration information of a certain frequency point only contains frequency point information, but does not carry specific resource configuration information, it indicates that the specific resource configuration information related to the frequency point is the same as the previous frequency point, which is implicit. For example, when the frequency resource is the same as the configured frequency information, the network side carries the reference frequency information in the HSUPA physical resource configuration information of the frequency point, and indicates that the UE uses the frequency point. The parameter configuration is the same as that of the reference frequency. This is the display mode. Of course, the network side can also choose to send the HSUPA physical resource configuration information of all frequency points to the terminal through RRC messages under any circumstances.

The above HSUPA physical resources include but are not limited to: midamble code and time slot used by E-AGCH, midamble code and time slot used by E-HICH, and midamble code and time slot used by E-PUCH.

The present invention also provides a configuration system for an HSUPA physical resource, where the system includes a network side and a terminal;

The network side is configured to send, by using an RRC message, HSUPA physical resource configuration information of the at least one frequency point to the terminal.

When the resource configuration information of the frequency point is the same as the previous frequency point, the network side sends the HSUPA physical resource configuration information of the at least one frequency point to the terminal by using an RRC message: the HSUPA physics of the frequency point in the RRC message Only the frequency information is included in the resource configuration information.

The HSUPA physical resources are: a midamble code and a time slot used by the E-AGCH, and/or The midamble code and time slot used by the E-HICH, and/or the midamble code and time slot used by the E-PUCH.

HSUPA multi-carrier bundling capability. Example 4 In this embodiment, when the network side decides that the terminal needs to use the multiple carriers to perform the HSUPA service transmission at the same time, the RNC notifies the terminal of the multi-carrier bundling of the UPA service by using the radio bearer setup message. FIG. 1 is the air interface multi-carrier bundled HSUPA service according to the fourth embodiment of the present invention. Schematic diagram of the configuration process, as shown in Figure 1, the method includes:

Step 101: The user accesses on the network side, and after the signaling is successfully established, the message is RRC.

CONNECTION SETUP COMPLETE notifies the RNC of the user's multi-carrier HSUPA capability.

In general, if the user supports HSUPA capability, the RNC decides to carry the user on the HSUPA channel. If the user supports multi-carrier HSUPA, the RNC notifies the user of the filling of the air interface message according to the multi-carrier HSUPA configuration.

Step 102: The RNC decision terminal performs HSUPA transmission on only one carrier frequency, only

The HSUPA configuration information is filled in the E-PUCH TS configuration list cell, and Ul-E-PUCH-MultiCarrier-Information does not need to be filled out.

Here, if the RNC decides that the user needs to use multiple carriers for HSUPA service transmission at the same time, it needs to fill in the time slot of the EPUCH channel on each carrier frequency and the midamble code configuration information to be sent to the user. If the carrier frequency HSUPA information configured by the RNC is consistent, the configuration information is filled in the E-PUCH TS configuration list cell, and the frequency information in the Ul-E-PUCH-MultiCarrier-Information is filled in; if the carrier frequency HSUPA is configured If the configuration information is inconsistent, the configuration information of one carrier frequency is filled in the E-PUCH TS configuration list cell, and the remaining carrier frequencies are filled in the cells in the Ul-E-PUCH-MultiCarrier-Information.

Here, when the multi-carrier HSUPA service is transmitted, the time slot, channelization code, and midamble code configuration of the scheduling channel EAGCH on each carrier frequency need to be sent to the terminal. Fill in the configuration information into the E-AGCH set configuration cell and indicate the frequency point where each EAGCH channel is located;

Here, the RNC decision terminal only uses this carrier frequency when performing HSUPA transmission on one carrier frequency. The Nehich, or EI, or time slot, or midamble code configuration information of the EHICH channel on which the feedback data is received is filled in to the E-HICH Information cell parameter, and the E-HICH-MultiCarrier-Information cell is not required to be filled;

When the RNC decision terminal performs HSUPA transmission on multiple carrier frequencies, it needs to feed back the data reception status of the carrier frequency of each HSUPA service transmission, and fill in the Nehich, EI, time slot, and midamble code configuration information of each carrier frequency EHICH channel. In the E-HICH-MultiCarrier-Information cell, there is no need to fill in the E-HICH Information cell.

Step 103: The network side sends a radio bearer (RB) setup message to the terminal. When the terminal needs to use multiple carriers to perform HSUPA service transmission at the same time, fill in the corresponding EAGCH, EPUCH, and EHICH information parameters in the RB setup message according to the foregoing principles.

Step 104: After receiving the RB setup message on the network side, the terminal performs internal physical information configuration processing according to the EAGCH, EPUCH, and EHICH information parameters respectively allocated by each carrier when the multi-carrier bundled HSUPA service is in the RB setup message, and then the RB establishment is completed. The message is sent to the network side, indicating that the RB establishment process is configured.

Then, the network side and the terminal can transmit the multi-carrier bundled HSUPA service through the configured EAGCH, EPUCH, and EHICH resource information on each carrier frequency.

The above is only the preferred embodiment of the present invention and is not intended to limit the scope of the present invention. Industrial applicability
