The present invention relates to the field of channel power control in the technical field of wireless communication, in particular to an E-HICH power control method and device.

Background technique

HSPA (High-Speed Packet Access) in TD-SCDMA (Time Division-Synchronous Code Division Multiple Access) network and WCDMA (Wideband Code Division Multiple Access) network In the system, the indication channel E-HICH (E-DCH HARQ Indication Channel) of E-DCH (Enhanced Dedicated Channel, Enhanced Dedicated Channel) HARQ (Hybrid Automatic Repeat Request, Hybrid Automatic Repeat Request) is introduced into the system. , HARQ indicator channel of E-DCH), which is used for the base station NodeB to feed back the ACK/NACK information of each E-DCH transport block to the user terminal UE. E-HICH occupies a downlink physical channel with SF=16, occupies 80 effective bits for transmission in one transmission time slot, and reserves 8 empty bits for undefined in the protocol.

At present, the transmission power of the E-HICH is not clearly defined in the agreement, but only indicates that the transmission power of the E-HICH of each user can be independently set by the NodeB. In actual operation, in order to ensure the reliability of E-HICH transmission, NodeB generally allocates all the remaining transmit power in a transmission time slot to E-HICH, and the remaining transmit power in a transmission time slot is often very small. Large, so the transmission power of E-HICH is too large, which not only causes excessive power consumption, but also generates strong downlink interference to the same time slot of other cells, increases the noise floor of the network, and thus reduces the overall network quality .

Detailed ways

In order to reduce the transmission power of E-HICH, thereby reducing the downlink interference generated by the same time slot of other cells, and then improving the overall network quality, the embodiment of the present invention provides an E-HICH power control method and devices, the preferred embodiments of the present invention will be described below in conjunction with the accompanying drawings. It should be understood that the preferred embodiments described here are only used to illustrate and explain the present invention, and are not intended to limit the present invention. And in the case of no conflict, the embodiments in the present application and the features in the embodiments can be combined with each other.

An embodiment of the present invention provides an E-HICH power control method, as shown in FIG. 1 , including:

Step S101. Obtain the transmit power of a designated downlink control channel of a user.

Step S102: Determine the transmit power of the user's E-HICH according to the acquired transmit power of the designated downlink control channel.

In the above step S102, specifically, based on the preset offset between the transmit power of the designated downlink control channel and the transmit power of the user's E-HICH, according to the acquired transmit power of the designated downlink control channel, determine the user's The transmit power of the E-HICH, for example, determines the transmit power of the user's E-HICH as the difference between the acquired transmit power of the specified downlink control channel minus the preset offset.

In the embodiment of the present invention, it is considered that closed-loop power control is more reasonable than open-loop power control for controlling transmission power. Therefore, the above-mentioned specified downlink control channel may specifically be a downlink control channel using closed-loop power control.

Preferably, in the downlink control channel using closed-loop power control, the user-specific downlink accompanying DPCH (Dedicated Physical Channel, dedicated physical channel) can be selected. In the HSPA system, the system will allocate the user-specific DPCH for each online HSPA user. Accompanied by DPCH, this channel is used to transmit the signaling information of the user as a reference for power control and beamforming. Since each user has its own dedicated accompanying DPCH, it may be preferred to select the downlink accompanying DPCH as the above-mentioned designated downlink control channel.

However, in the HSPA+ system, due to the cancellation of the accompanying DPCH, other downlink control channels using closed-loop power control can be considered, for example, HS-SCCH (High Speed Shared Control Channel, high-speed shared control channel) and HS-SICH (High Speed Shared InformationChannel, high-speed shared information channel) are channels related to HS-DSCH (High Speed Downlink Shared Channel, high-speed downlink shared channel), a pair of closed-loop power control channels, so you can choose the downlink control channel HS-SCCH As the above designated downlink control channel.

As another example, E-PUCH (E-DCH Physical Uplink Channel, E-DCH Physical Uplink Channel) and E-AGCH (E-DCH Absolute Grant Channel, E-DCH Absolute Grant Channel) are a pair of closed-loop power control channels, so they can The downlink control channel E-AGCH among them is selected as the designated downlink control channel.

In addition, the above-mentioned method shown in FIG. 1 provided by the embodiment of the present invention may specifically be executed by an RNC (RadioNetwork Controller, radio network controller), and inform the base station of the determined transmit power of the E-HICH, or the base station may base the The acquired transmission power of the specified downlink control channel determines the transmission power of the user's E-HICH.

The method and device provided by the present invention will be described in detail below with specific embodiments in conjunction with the accompanying drawings.

Example 1:

In Embodiment 1 of the present invention, a scheme for controlling the transmission power of the user's E-HICH based on the transmission power of the user-specific downlink accompanying DPCH is described in detail.

In the TD-SCDMA system, the encoding process of the E-HICH channel is shown in Figure 2, where the E-HICH is used for the NodeB to feed back the ACK/NACK information of each corresponding E-DCH transport block to the UE, and the information bit length is only 1 bit, this 1 bit information is expanded to 80 bits with 80 bit Hadmard orthogonal code, and channel coding is completed, then 8 bits of idle data are filled during interleaving and physical channel allocation, and the 88 bits are transmitted using the time slot format shown in Figure 2 The data.

It can be seen that the coding redundancy of E-HICH is very large, so its coding gain is also very large. Such a large coding gain can ensure that the UE can correctly read the one-bit information of ACK/NACK carried by the E-HICH even in an environment with poor channel quality. Therefore, the current method of allocating the remaining transmission power of this time slot to E-HICH wastes carrier power, and causes interference to the entire network due to excessive transmission power allocated to E-HICH, reducing the The overall quality of the network.

In the HSPA system, the system allocates a user-specific companion DPCH for each online HSPA user, and this channel is used to transmit the user's signaling information as a reference for power control and beamforming. Since each user has its own accompanying DPCH, Embodiment 1 of the present invention proposes a scheme for controlling the transmission power of the user's E-HICH based on the transmission power of the user-specific downlink accompanying DPCH, as shown in Figure 1 above. process shown.

In the above step S101, the transmission power of the user-specific downlink accompanying DPCH is obtained, and in the above step S102, the transmission power of the user's E-HICH is determined to be the acquired transmission power of the downlink accompanying DPCH minus the preset offset The preset offset may be corresponding to the downlink accompanying DPCH.

Among them, the setting of the preset offset can be set according to the characteristics of the downlink accompanying DPCH and E-HICH and the actual network conditions. For example, the preset offset can be set to zero, and the user-specific downlink to be acquired The transmission power of the accompanying DPCH is used as the transmission power of the user's E-HICH;

The preset offset can also be set as a negative number, that is, the determined transmission power of the user's E-HICH is greater than the transmission power of the user-specific downlink accompanying DPCH;

Since the coding gain of the E-HICH is much greater than that of the downlink associated DPCH, it is determined that the transmit power of the user's E-HICH is equal to or greater than the transmit power of the user's dedicated downlink associated DPCH, which can ensure that the UE has a good understanding of the E-HICH. Accurate receipt of data;

However, just because the coding gain of the E-HICH is much greater than the coding gain of the downlink accompanying DPCH, it is preferable to set the preset offset as a positive number, that is, the determined transmit power of the user's E-HICH It is smaller than the transmission power of the user-specific downlink accompanying DPCH, so as to better save the carrier power, so as to better reduce the downlink interference generated by the same time slot of other cells, and thus more effectively improve the overall network quality.

Example 2:

In the HSPA+ system, since the companion DPCH is canceled, other downlink control channels using closed-loop power control can be considered. In Embodiment 2 of the present invention, it is proposed that based on the transmission power of the user's HS-SCCH or E-AGCH, the user's E - The scheme of controlling the transmission power of HICH, which is described below in detail by taking HS-SCCH as an example, and the specific processing flow is shown in FIG. 1 .

In the above step S101, the transmission power of the user's HS-SCCH is obtained, and in the above step S102, it is determined that the transmission power of the user's E-HICH is the obtained transmission power of the HS-SCCH minus the preset offset difference, the preset offset may correspond to the HS-SCCH.

Among them, the setting of the preset offset can be set according to the characteristics of HS-SCCH and E-HICH and the actual network conditions, which is similar to the principle of setting the preset offset in the above-mentioned embodiment 1. For example, the The preset offset is zero, and the preset offset can also be set as a negative number. Since the coding gain of the E-HICH is greater than the coding gain of the HS-SCCH, it is determined that the transmit power of the E-HICH of the user is equal to or greater than the The transmission power of the user's HS-SCCH can ensure that the UE can accurately receive the data carried by the E-HICH; preferably, the preset offset can also be set as a positive number, that is, the determined E-HICH of the user The transmission power is lower than the transmission power of the user's HS-SCCH, so as to better save the carrier power, so as to better reduce the downlink interference generated by the same time slot of other cells, and thus improve the overall network quality more effectively .

Different from the solution based on the downlink accompanying DPCH in the above-mentioned embodiment 1, since the HS-SCCH is a time-division shared channel between users, it is not a dedicated channel allocated for each user, so in the same transmission subframe, there may be There is only the E-HICH of the user, but no HS-SCCH of the user. Therefore, in Embodiment 2 of the present invention, the following specific processing method is proposed for the above step S101:

When there is an HS-SCCH in the transmission subframe (that is, the current transmission subframe) in which the E-HICH of the user is transmitted, obtain the transmission power of the HS-SCCH of the user in the current transmission subframe;

When there is no HS-SCCH in the transmission subframe of the user's E-HICH, obtain the transmit power of the user's HS-SCCH in other transmission subframes; preferably, for other transmission subframes, it can be preferentially selected from The transmission power of the user's HS-SCCH is obtained in a transmission subframe that is closer to the current transmission subframe.

Correspondingly, the following specific processing methods are proposed for the above step S102:

When the transmission power of the user's HS-SCCH in the current transmission subframe is obtained in step S101, determine the transmission power of the user's E-HICH, which is the transmission of the user's HS-SCCH in the current transmission subframe obtained The difference between the power minus the first preset offset, where the first preset offset corresponds to the current transmission subframe;

When what is acquired in step S101 is the transmission power of the user's HS-SCCH in other transmission subframes, determine the transmission power of the user's E-HICH, which is the obtained transmission power of the user's HS-SCCH in the other transmission subframes The difference between the transmit power and the second preset offset, where the second preset offset is a preset offset corresponding to the number of subframes between the current transmission subframe and the other transmission subframe; and , preferably, the larger the number of subframes between the current transmission subframe and the other transmission subframes, the smaller the absolute value of the corresponding second preset offset can be set, so that the determined E of the user -The transmission power of the HICH is closer to the transmission power of the user's HS-SCCH in the other transmission subframe, for example, when the number is between 1-4, a corresponding second preset offset is set, when the When the quantity is between 5-12, another corresponding second preset offset is set, and the absolute value of the latter is greater than the absolute value of the former.

For the scheme of controlling the transmission power of the user's E-HICH based on the transmission power of the user's E-AGCH, it is similar to the above-mentioned scheme of controlling the user's E-HICH based on the user's HS-SCCH, and will not be carried out here. A detailed description.

Preferably, Embodiment 2 of the present invention also proposes a scheme for controlling the transmission power of the user's E-HICH based on the transmission power of the user's HS-SCCH and E-AGCH, as shown in Figure 3, including:

Step S301 , judging whether there is HS-SCCH in the transmission subframe (that is, the current transmission subframe) for transmitting the E-HICH of the user, if yes, proceed to step S302 , otherwise, proceed to step S303 .

Step S302. Obtain the transmission power of the user's HS-SCCH in the current transmission subframe.

Step S303, judging whether there is an E-AGCH in the current transmission subframe, if yes, go to step S304, otherwise, go to step S305.

Step S304, acquiring the transmit power of the user's E-AGCH in the current transmission subframe.

Step S305, obtain the transmission power of the user's HS-SCCH or E-AGCH in other transmission subframes, for example, from other transmission subframes of the user's HS-SCCH or E-AGCH, obtain the transmission power of the current transmission subframe The transmission power of the user's HS-SCCH or E-AGCH in other transmission subframes with the least number.

Step S306, based on the acquired transmit power of HS-SCCH or E-AGCH, use the corresponding preset offset to determine the transmit power of the user's E-HICH. For the specific determination method, refer to the above description, which will not be described here. Then describe in detail.

The power control scheme, in other embodiments, other specific control schemes can also be proposed, for example, the transmission power of multiple downlink control channels of the user (such as downlink accompanying DPCH, HS-SCCH and E-AGCH) can be obtained, Select the maximum transmit power, or the minimum transmit power, or the average transmit power as a reference for controlling the transmit power of the user's E-HICH, and determine the transmit power of the user's E-HICH based on the preset offset , the specific processing flow will not be described in detail.
