Furthermore, features described with respect to some examples may be combined into other examples.
Referring to fig. 1, fig. 1 is a schematic flowchart of a data transmission method provided in an embodiment of the present application, where the method is applied to a terminal, and in the embodiment of the present application, the method includes:
s101, determining path loss of data transmission in a millimeter wave frequency band.
The method provided by the embodiment of the present application can be applied to various terminals that need to transmit data through a wireless network, including but not limited to, terminals such as a mobile phone, a notebook computer, a digital broadcast receiver, a PDA (personal digital assistant), a PAD (tablet computer), a PMP (portable multimedia player), a vehicle-mounted terminal (e.g., a car navigation terminal), and the like. The terminal in the embodiment of the application is a terminal supporting data transmission in a millimeter wave frequency band.
Generally, the frequency band of 5G is divided into two types by taking 6GHz as a central point. The first is a frequency band below 6GHz, which is collectively referred to as Sub6GHz, including 700MHz, 2.6GHz, 3.5GHz, 4.9 GHz; the second is a frequency band above 6GHz, which is called millimeter wave.
The millimeter wave frequency band signal has the defects of high attenuation, easy blockage and short coverage distance; its advantages are very large bandwidth, narrow beam, high security and secrecy. The Sub6 band has the advantage of long transmission distance and the disadvantage of relatively small bandwidth. In the subsequent 5G coverage, a Sub6 frequency band and a millimeter wave frequency band exist at the same time, and the method has great research value on how to select a proper frequency band in a proper scene according to the characteristics of Sub6 and millimeter waves.
Alternatively, S101 may include:
receiving a downlink reference signal;
measuring a received power of the downlink reference signal;
determining the path loss based on the received power.
The base station may transmit a downlink reference signal to the terminal and the terminal may measure the received power based on the downlink reference signal. In this case, the CRS can be taken as an example of the downlink reference signal. The CRS is transmitted through 1 OFDM (Orthogonal Frequency Division Multiplexing) symbol in each slot of the subframe.
After measuring the reception power based on the CRS received at a predetermined time interval, the terminal may measure the reception power of the downlink reference signal and determine the path loss based on the reception power.
And S102, if the path loss is lower than the threshold loss, carrying out data transmission through a millimeter wave frequency band.
The threshold loss can be set according to specific application scenarios. It should be noted that if the threshold loss is set too high, a large amount of data may be transmitted through the millimeter wave frequency band, but packet loss, network delay, and the like may occur in the data transmission process, which affects the quality of data transmission. If the threshold loss is set too low, most data will still be transmitted through the conventional Sub6 band, which affects the efficiency and capacity of data transmission.
And S103, if the path loss is higher than the threshold loss, carrying out data transmission through a Sub6 frequency band.
According to the method provided by the embodiment of the application, the path loss of data transmission is carried out according to the millimeter wave frequency band, the data transmission is carried out through the millimeter wave frequency band or the Sub6 frequency band, and the data transmission is carried out through the millimeter wave frequency band under the condition that the path loss is lower than the threshold loss. Therefore, the method of the embodiment of the application can solve the problem that no excessive frequency bands can be used for bearing the increased network service in the traditional mobile communication system.
Optionally, the method further comprises:
and sending data transmission information, wherein the data transmission comprises indication information, and the indication information is used for representing whether data transmission is carried out through a millimeter wave frequency band.
The terminal sends the data transmission information containing the indication information to the base station, and the base station can determine the mode of the terminal for data transmission according to the indication information. On one hand, the base station can conveniently and efficiently transmit data with the terminal; on the other hand, the method is beneficial to the base station to perform resource integration and optimization at a higher level.
Optionally, the data transmission information includes at least one of: the millimeter wave band carries out information on data transmission length, indication information on whether to periodically transmit the data transmission information, and period information on transmitting the data transmission information.
The terminal sends the data transmission information containing the information to the base station, and the base station can determine and negotiate the mode of the terminal for data transmission according to the data transmission information, so that the base station can conveniently receive and analyze the data sent by the terminal and return the related information to the terminal.
Referring to fig. 2, fig. 2 is a schematic flowchart of another data transmission method provided in this embodiment of the present application, where the method is applied to a terminal, and in this embodiment of the present application, the method includes:
s201, sending a millimeter wave detection signal.
S202, receiving a reference detection signal, and calculating the path loss according to the reference detection signal, wherein the reference detection signal is generated by the base station based on the millimeter wave detection signal.
SRS (Sounding Reference Signal) is used to enable channel quality estimation for frequency selective scheduling on the uplink. In this case, the SRS transmission is performed regardless of the uplink data transmission and/or the uplink control information transmission. The SRS may be used to enhance power control or to support the use of various startup functions for UEs that have not recently been scheduled. For example, various startup functions include MCS (Modulation and Coding Scheme) selection, initial power control for data transmission, TA (Timing Advance), and so-called frequency semi-selection scheduling. At this time, the frequency semi-selective scheduling means that frequency resources are selectively allocated for a first slot of a subframe and pseudo-randomly frequency-hopped to a different frequency in a second slot.
Further, under the assumption that the radio channel is reciprocal between the uplink and the downlink, the SRS can be used for downlink channel quality estimation. This assumption shares the same spectrum in the uplink and downlink and is particularly effective in time division duplex systems where the time domains are generally separated.
The UE may periodically perform SRS transmission at time intervals of 2ms or 160ms based on the SRS transmission parameters.
S203, judging whether the path loss is lower than the threshold loss.
If the path loss is lower than the threshold loss, the following step S204 is performed. If the path loss is higher than the threshold loss, the following step S205 is performed.
And S204, if the path loss is lower than the threshold loss, carrying out data transmission through a millimeter wave frequency band.
And S205, if the path loss is higher than the threshold loss, carrying out data transmission through a Sub6 frequency band.
S206, determining the path loss of data transmission in the millimeter wave frequency band.
Because the network environment is constantly changing, the path loss of data transmission in the millimeter wave band can be continuously determined in a set period, and the switching between the millimeter wave band and the Sub6 band can be automatically performed according to the path loss. Therefore, the method provided by the embodiment of the application can improve the utilization efficiency of the network while ensuring the transmission quality.

The terminal and the base station may communicate related information with each other, and in case that both the terminal and the base station support data transmission through the millimeter wave band, the following step S302 is performed. The terminal and the network device in the wireless access system may also communicate related information with each other, and in case that both the terminal and the network device support data transmission through the millimeter wave frequency band, the following step S302 is performed.
S302, determining the path loss of data transmission in the millimeter wave frequency band.
And S303, if the path loss is lower than the threshold loss, carrying out data transmission through a millimeter wave frequency band.
And S304, if the path loss is higher than the threshold loss, carrying out data transmission through a Sub6 frequency band.
In the method of the embodiment of the application, before determining the path loss of data transmission in the millimeter wave frequency band, whether the wireless access system supports data transmission in the millimeter wave frequency band is detected. And under the condition that the wireless access system supports data transmission in the millimeter wave frequency band, detecting the path loss, and further judging whether the millimeter wave frequency band can be adopted for data transmission.
