Description

Method and device for configuring maximum transmission power of cell carrier

technical field

The present invention relates to the technical field of cell carrier control in the third generation mobile communication system, in particular to a method for configuring the maximum transmission power of a cell carrier in a Time Division Synchronization Code Division Multiple Access (TD-SCDMA, Time Division Synchronization Code Division Multiple Access) system and device.

Background technique

At present, according to the regulations of the China Communications Standards Association (CCSA), in the TD-SCDMA system, when a cell uses a carrier to transmit downlink services, the transmission power of the carrier cannot exceed a preset value. The preset value is called the maximum transmission power of the carrier. When a cell supports multiple carriers to transmit services, one of the carriers is the primary carrier and the other carriers are secondary carriers, and the maximum downlink transmission power of each carrier should be equal.

According to the current standard, when a cell is established, the network side can configure the same maximum transmission power for multiple carriers in the cell through the cell setup request (CELL SETUP REQUEST) system message. After the cell is established, the network side can also uniformly reconfigure the maximum transmission power of each carrier in the cell through the cell reconfiguration request (CELL RECONFIGURATION REQUEST) system message.

When a cell is established, the network side adds the maximum transmission power information of each carrier in the cell to the highest-level maximum transmission power information element in the cell establishment request system message, so as to realize the unified configuration of the maximum transmission power of multiple carriers in the cell.

After the cell is established, the network side can also add the new maximum transmission power information of each carrier to the maximum transmission power information element in the cell reconfiguration request system message, so as to realize the unified reconfiguration of the maximum transmission power of multiple carriers in the cell .

Table 1 shows the system message after adding the maximum transmission power information of the cell carrier. In the cell establishment request or cell reconfiguration request system message, there are many cells/cell groups. For simplicity, only the maximum transmission power information is given here. Transmit Power Cell. It can be seen from Table 1 that the maximum transmission power of each carrier in the cell is uniformly configured as 25dBm.

Table 1

Cell/cell group name Existence scope cell type Description of cell function critical value Assign threshold ... ... ... ... ... ... ... Maximum transmission power must 25dBm 9.2.1.40 yes reject ... ... ... ... ... ... ...

It can be seen that this method of uniformly configuring the maximum transmission power of all carriers in the cell is not flexible enough, because in actual situations, different services are transmitted, and the maximum transmission power required by the carriers is also different. However, the existing standard stipulates that the maximum transmission power of each carrier is set equally, which obviously does not take into account the requirements of the carrier for the maximum transmission power when transmitting different services.

In addition, if the maximum transmission power of the cell carrier is configured according to the existing standard, the transmission power of the cell will be wasted. Because in the TD-SCDMA system, it is necessary to use the carrier to transmit the downlink service according to the time slot (TS, Time Slot). In the frame structure of the TD-SCDMA system, there are 7 time slots for transmitting services, and the 7 time slots are TS0-TS6 respectively. In the TS0 time slot, the primary carrier is used to transmit broadcast messages to the cell, while the secondary carrier does not transmit any message. Since only the primary carrier is transmitting messages in the TS0 time slot and the secondary carrier is not transmitting any messages, a waste of transmission power is caused. This waste is more obvious when the cell has multiple secondary carriers.

Contents of the invention

Detailed ways

The core idea of the present invention is to add information elements in the cell establishment request/cell reconfiguration request system message, and add the maximum transmission power information of the primary and secondary carriers of the cell into the cell establishment request/cell reconfiguration request system message respectively. In addition, the maximum transmission power of the primary and secondary carriers of the cell can be configured separately.

The method will be further specifically described below through examples.

When the cell is established, the maximum transmission power is configured for the primary and secondary carriers of the multi-carrier cell through the cell establishment request system message. The method will be described in detail through Embodiment 1 below. FIG. 1 is a flow chart of Embodiment 1.

In step 101, add the frequency point information of the main carrier of the cell in the highest-level UTRA absolute radio frequency channel sequence number (UARFCN, UTRA Absolute Radio Frequency Channel Number) information element of the cell establishment request system message, and add the frequency point information of the main carrier of the cell in the highest-level maximum transmission power signal The maximum transmission power information of the main carrier of the cell is added to the element.

Wherein, since the number of secondary carriers in the cell is 2, the value range of the UARFCN low code rate information element is set to 0..1. When the number of secondary carriers in the cell is N, the value range of the UARFCN low code rate information element is set to 0..N-1.

Embodiment 1 is a method of configuring maximum transmission power for primary and secondary carriers of a multi-carrier cell through a cell setup request system message when a cell is established. After the cell is established, the cell reconfiguration request system message can also be used to configure the maximum transmission power for the main carrier and the auxiliary carrier of the cell respectively. The method will be described in detail through Embodiment 2 below, and FIG. 2 is a flow chart of Embodiment 2.

In step 201, the maximum transmission power information of the primary carrier of the cell is added to the maximum transmission power information element of the highest level in the cell reconfiguration request system message.

Then, in step 203, the frequency point information of each secondary carrier in the cell is added to each of the newly created UARFCN cells, and in step 204, the maximum transmission power of each secondary carrier in the cell is added to the corresponding maximum transmission power cell.

More specifically, it is assumed that a multi-carrier cell includes 1 main carrier and 2 auxiliary carriers, the frequency points of the auxiliary carriers are 105MHz and 115MHz respectively, and the maximum transmission power configured for the main and auxiliary carriers are 25dBm, 27dBm and 25dBm respectively. Then, in the cell establishment request system message according to the above steps, after completing the configuration of the primary and secondary carriers of the cell, the cell establishment request system message is shown in Table 3.

＞＞＞Maximum transmission power optional 25dBm 9.2.1.40 The maximum transmission power of the auxiliary carrier yes reject ... ... ... ... ... ... ...

The above is the method of adding the maximum transmission power of the primary and secondary carriers in the cell reconfiguration request system message. If you want to modify the maximum transmission power of the primary and secondary carriers of the cell through the cell reconfiguration request system message, this method is similar to the above method ,include:

The maximum transmission power information of the primary carrier of the cell is added to the maximum transmission power information element of the highest level in the cell reconfiguration request system message.

Then, in the cell reconfiguration request system message UARFCN modify the low code rate information (UARFCN Information To Modify LCR) information element one level lower, establish the UARFCN information element and the maximum transmission power information element of each auxiliary carrier in the cell, and according to the auxiliary carrier Correspondingly, set the value range of the UARFCN to modify the low code rate information cell.

Then, add the frequency point information of each auxiliary carrier of the cell into the newly created UARFCN information elements, and add the maximum transmission power of each auxiliary carrier of the cell into the corresponding maximum transmission power information element.

More specifically, assuming that a multi-carrier cell includes 1 main carrier and 2 auxiliary carriers, the frequency points of the auxiliary carriers are 105MHz and 115MHz respectively, and the maximum transmission power of the main and auxiliary carriers is modified to 27dBm, 25dBm and 27dBm respectively. Then, in the cell reconfiguration request system message according to the above steps, after completing the configuration of the primary and secondary carriers of the cell, the cell reconfiguration request system message is shown in Table 4.

In Embodiment 1 and Embodiment 2, although the primary and secondary carriers in the multi-carrier cell are configured separately, for each carrier, the maximum transmission power of the carrier in all time slots is the same. Since in the TS0 time slot, the cell only uses the primary carrier to transmit broadcast messages to the cell, but the secondary carrier does not transmit any message, so the transmission power of the secondary carrier is wasted in the TS0 time slot. This waste is more obvious when the cell has multiple secondary carriers. In order to solve this problem, the present invention also provides a method for configuring the maximum transmission power of the cell carrier, which can not only configure the maximum transmission power of the main carrier and the auxiliary carrier in the multi-carrier cell respectively, but also configure the maximum transmission power of the time slot TS0 and other time slots. Configure the maximum transmission power of the carrier. The method will be further described in detail below in conjunction with the examples.

When the cell is established, the maximum transmission power of the main carrier in the TS0 time slot and other time slots, and the maximum transmission power of each auxiliary carrier in the TS0 time slot and other time slots can be configured through the cell establishment request system message. The method is described below through Embodiment 3 To illustrate in detail, FIG. 3 is a flow chart of Embodiment 3.

In step 301, the frequency point information of the main carrier of the cell is added to the UARFCN information element of the highest level in the cell establishment request system message.

In step 303, the UARFCN information element, the maximum transmission power information element of the TS0 time slot and the maximum transmission power information element of each secondary carrier of the cell are established at a level lower than the UARFCN low code rate information element of the cell establishment request system message, and The value range of the UARFCN low code rate information cell is set accordingly according to the number of auxiliary carriers.

Then, in step 304, the frequency point information of each secondary carrier in the cell is respectively added into the newly created UARFCN cells, and in step 305, the maximum transmission power of each secondary carrier in the TS0 time slot is added into the corresponding TS0 In the maximum transmission power information element of the time slot, the maximum transmission power of each secondary carrier in other time slots is added to the corresponding maximum transmission power information element.

More specifically, assuming that a multi-carrier cell includes 1 primary carrier and 1 secondary carrier, the frequency of the secondary carrier is 115MHz, the maximum transmission power of the primary carrier in the TS0 time slot and other time slots is configured as 30dBm and 25dBm, and the TS0 The maximum transmission power configuration of the time slot and the secondary carrier of other time slots is 10dBm and 25dBm. Then, in the cell establishment request system message according to the above steps, after completing the configuration of the primary and secondary carriers of the cell, the cell establishment request system message is shown in Table 5.
