detailed description

The technical solutions in the embodiments of the present application are clearly and completely described in the following with reference to the accompanying drawings in the embodiments of the present application. It is a part of the embodiments of the present application, and not all of the embodiments. Based on the embodiments in the present application, those obtained by those of ordinary skill in the art without creative efforts Other embodiments are within the scope of the present disclosure.

FIG. 1 is a schematic structural diagram of Embodiment 1 of a wireless communication base station according to the present application. As shown in FIG. 1, the wireless communication base station of this embodiment may include:

Unlicensed band RF front end unit 101, WiFi baseband unit 102, channel mapping unit 103, and LTE baseband unit 104;

The unlicensed band radio frequency front end unit 101 is respectively connected to the WiFi baseband unit 102 and the LTE baseband unit 103;

The WiFi baseband unit 102 is connected to the LTE baseband unit 104 through a channel mapping unit 103.

among them,

The unlicensed band radio frequency front end unit 101 is configured to receive each WiFi radio signal, and send an LTE radio signal according to an available channel;

The WiFi baseband unit 102 is configured to measure each received signal strength of each WiFi radio signal, and determine the available channel;

The channel mapping unit 103 is configured to convert a WiFi channel transmission corresponding to the available channel into an LTE channel transmission;

The LTE baseband unit 104 is configured to process a radio signal to be transmitted according to an LTE protocol and the LTE channel to generate the LTE radio signal.

Specifically, in the existing base station device, especially the small base station device, there are usually LTE and WiFi functions, wherein the LTE system is applied to the licensed frequency band, and the WiFi system is applied to the unlicensed frequency band. As shown in Figure 2, the two systems are independent of each other. The WiFi device has the functions of channel measurement and channel selection in the baseband section due to its support for dynamic frequency selection. LTE devices have only common signal processing units.

When the technical solution of the embodiment is implemented, the LTE system can be used for the unlicensed frequency band by modifying the existing wireless communication base station, that is, adding the channel mapping unit 103 between the WiFi baseband unit 102 and the LTE baseband unit 104. the goal of.

In addition, since the 4G LTE system has centralized scheduling compared to the WiFi system, Features such as HARQ ensure high-quality performance transmission in multi-user situations and a more secure two-way authentication system. By using the LTE system for unlicensed frequency bands, signals transmitted in unlicensed frequency bands can achieve high-quality performance transmission, thereby fully utilizing the large bandwidth of the 5 GHz band.

More specifically, the added channel mapping unit 103 mainly performs the matching between the WiFi channel number and the LTE EARFCN (E-UTRA Absolute Radio Frequency Channel Number) parameters, as follows:

WiFi channel center frequency (MHz) = channel start frequency + 5x channel number, for example, in the 5GHz band, the channel start frequency is 5000MHz, when the channel number is 36, the WiFi channel center frequency = 5000 + 5x36 = 5180MHz, when the channel When the number is 40, the WiFi channel center frequency is 5000+5x40=5200MHz.

The LTE system uses another way of recording frequencies. First define the EARFCN table in the standard:

The specific frequency band corresponding formula is: FDL=FDL_low+0.1 (NDL-NOffs-DL), where NDL is the downlink EARFCN value.

The frequency indication methods of the two systems are different, and a matching table of corresponding LTE EARFCN values under different WiFi channel values needs to be generated.

Assume that the WiFi channel is number 36 and the corresponding frequency is 5180 MHz.

Then 5180MHz=5150+0.1*(NDL-46790), NDL=47090. In this case, the WiFi channel 36 establishes a match with the LTE EARFCN 47090.

Assume that the WiFi channel is number 40 and the corresponding frequency is 5200 MHz.

Then 5200MHz=5150+0.1*(NDL-46790), NDL=47290. In this case, the WiFi channel 40 establishes a match with the LTE EARFCN 47290.

On the basis of the foregoing embodiment, the unlicensed band radio frequency front end unit 101 specifically includes:

WiFi unlicensed band RF front end unit 101a.

Specifically, the unlicensed band radio front end unit 101 may correspond to the WiFi unlicensed band radio front end unit 101a of the existing base station device.

Based on the foregoing embodiment, the WiFi baseband unit 102 is specifically configured to: determine the available channel according to each received signal strength.

Specifically, the WiFi baseband unit 102 can measure which frequency radio signals and their corresponding signal strengths are already present in the current environment, and can select available channels from the unlicensed frequency bands according to the measured strength. For example, a channel that has not been used may be selected from an unlicensed frequency band, or a channel with a weak signal strength may be selected as an available channel to avoid interference between signals.

FIG. 3 is a schematic structural diagram of Embodiment 2 of a wireless communication base station according to the present application. As shown in FIG. 3, based on the foregoing embodiment, the WiFi baseband unit 102 specifically includes: a channel measurement subunit 102a and a channel selection subunit 102b; and the unlicensed band radio frequency front end unit 101 and the The channel measurement sub-single 102a, the channel selection sub-unit 102b, and the channel mapping unit 103 are sequentially connected;

among them,

The base station further includes: a channel correction unit 105;

The channel correction unit 105 is respectively connected to the channel measurement subunit 102a and the channel selection subunit 102b;

among them,

The channel correction unit is configured to correct a signal strength difference between the WiFi radio link and the LTE radio link.

Specifically, the channel correction unit 105 is specifically configured to:

The intensity of the radio signal to be transmitted is compensated according to the difference in signal strength.

The LTE unlicensed band RF front-end unit 101b is used for transmitting and receiving LTE signals in the unlicensed band (5 GHz), and the WiFi system only receives signals. After receiving the radio signal through the 5 GHz WiFi unlicensed band radio front end unit 101a, the channel measurement subunit 102a measures the received signal strength under different WiFi channels, for example, the reception strength under channel 36 is -72 dBm/20 MHz, under channel 40. The receiving intensity is -80dBm/20MHz. Since the feeding loss and the antenna gain of the LTE unlicensed band RF front end unit 101b and the WiFi unlicensed band RF front end unit 101a are different, the measured received signal strength needs to be corrected by the channel correcting unit 105, which will be described later. Then, through the channel selection algorithm built in the WiFi system, one available channel is selected from the plurality of available channels according to the modified received signal strength. Finally, the available channel is converted to the channel number of LTE through the channel mapping unit 103. The LTE baseband transmits the signal to the LTE unlicensed band radio front end unit 101b according to the selected channel and then sends the signal to the LTE signal to transmit and transmit the LTE signal in the unlicensed band, and supports the dynamic of the unlicensed band. Frequency selection requirements.

More specifically, the newly added channel correction unit 105 mainly corrects the case where the LTE radio link does not match the WiFi radio link.

The main mismatches are as follows:

Different antenna positions: When the WiFi antenna and the LTE antenna are built-in and the other is externally set, the loss is required due to the penetration loss of the fuselage. Make compensation.

For example, if the WiFi antenna is built-in and the LTE antenna is external, the penetration loss of the WiFi antenna compared with the LTE antenna is XdB (x>0); when the WiFi antenna is external and the LTE antenna is built in, the WiFi antenna is worn compared with the LTE antenna. The transmission loss is XdB (x < 0).

The antenna gain (including the feed loss) is different: assuming that the gain of the WiFi antenna is AdB and the gain of the LTE antenna is BdB, the difference needs to be compensated.

Spatial signal strength - X + A = WiFi received signal strength.

Spatial signal strength + B = LTE received signal strength.

Compensated LTE received signal strength = WiFi received signal strength + X-A + B.
