Description

Method and device for transmitting data

The present application claims priority to the Chinese Patent Application, filed on Sep. 29, 2017, the entire disclosure of which is hereby incorporated by reference.

Technical field

Background technique

A wireless local area network (WLAN) low frequency system operates in an unlicensed Unlicensed low frequency band and provides coverage using an omnidirectional antenna or a quasi-omnidirectional antenna. In order to avoid interference with other users, wireless-fidelity (WI-FI) devices need to listen to the channel before sending data. Data can only be sent when the channel is idle. This will still cause interference problems caused by hidden nodes. Therefore, the WI-FI system introduces a request to send (RTS)/clear to send (CTS) handshake mechanism, and carries information such as a transceiver address and a data transmission duration in the handshake message. Data transmission is only performed when the handshake is completed and the link is confirmed to be free of interference.

However, for the high-frequency system, if the RTS/CTS handshake mechanism is still used, the transceiver device cannot be assisted to perform interference avoidance, which increases the time overhead for discovering the direction of the transmittable beam. Therefore, it is urgent to propose a method to achieve interference avoidance.

Detailed ways

The technical solutions in the present application will be described below with reference to the accompanying drawings.

The technical solution of the embodiment of the present application can be applied to various communication systems, for example, a global system of mobile communication (GSM) system, a code division multiple access (CDMA) system, and a wideband code division multiple access. (wideband code division multiple access, WCDMA) system, general packet radio service (GPRS), long term evolution (LTE) system, LTE frequency division duplex (FDD) system, LTE Time division duplex (TDD), universal mobile telecommunication system (UMTS), worldwide interoperability for microwave access (WiMAX) communication system, future fifth generation (5th Generation, 5G) system or new radio (NR) system.

The technical solution of the embodiment of the present application can be applied to a high frequency system. For example, a high frequency system refers to a communication system operating in a frequency band higher than 6G megahertz (GHz). The high-frequency system includes a large-scale antenna array Massive MIMO system, a 5G new air interface system, and a high-frequency system such as IEEE 11ad/ay.

For ease of understanding, some terms or concepts related to high frequency systems will be introduced below.

Hybrid beam forming (HBF): refers to two-stage hybrid beamforming consisting of analog beam forming (ABF) and digital beam forming (DBF).

Beam: refers to a beam with a higher antenna gain in a certain direction formed by multi-antenna beamforming than other directions. It is generally used to describe a beam that is narrower than an omnidirectional/quasi-omnidirectional beam and a wide beam. , no exact beam width limit.

Omnidirectional beam: A beam whose antenna pattern gain is consistent within 360 degrees of the antenna.

Quasi-omni beam: A beam formed by a single antenna or a partial sub-array. The antenna gain is higher in some directions than in other directions, but covers multiple narrow beams.

Phase shifter: A device that is capable of adjusting the phase of a wave. Different beam states and directions can be formed by adjusting different states of the phase shifter group.

1 is a schematic diagram of an example of a high frequency system. As shown in FIG. 1, the high frequency system is a narrow beam coverage system formed by digital weighting, and the high frequency system includes a baseband processing module and respective antenna ports, wherein the baseband processing module may include a digital beamforming DBF module. The high frequency system transmits signals or data through n beams corresponding to the respective antenna ports in FIG.

In the embodiment of the present application, the high frequency system may be a system of narrow beam coverage formed by analog beamforming ABF or hybrid beamforming HBF modulus two-stage weighting. 2 is a schematic view of another example of a high frequency system. As shown in FIG. 2, the HBF modular two-stage weighting system includes a baseband processing module, n radio frequency (RF) channels, a splitter, a phase shifter, and a power amplifier. , PA) and an antenna module, wherein the baseband processing module includes a digital beamforming DBF module. For each of the N RF channels, the phase shifter connected to the RF channel forms a first-stage analog beam by adjusting the phase of the phase shifter, and then the baseband processing module digitally weights the first-stage analog beam. The second-level data beam is obtained, thereby realizing the mapping of the signal flow to the RF channel, and finally the signal flow mapped to the RF channel is transmitted through the antenna according to the phase after phase shift of the phase shifter to form a beam.

Fig. 3 is a schematic view showing still another example of the high frequency system. The system shown in Figure 3 is also a HBF system. The system in FIG. 3 is similar to the system in FIG. 2. For the sake of brevity, the same concepts or terms as in FIG. 2 will not be described again. As shown in FIG. 3, the difference from FIG. 2 is that the system of FIG. 3 further includes a combiner. Each RF channel is connected to all antenna arrays, and the signals of the respective RF channels are combined by a combiner and output to each antenna array, and the phases of the phase shifters corresponding to the respective RF channels and the amplitude of the power amplifier are adjusted to form different Analog beam.

It should be understood that the foregoing is only an application scenario of the embodiment of the present application, and is not limited to the scope of protection of the embodiments of the present application. Actually, other application scenarios may be provided.

It should also be understood that the method for transmitting data in the embodiment of the present application can be applied to an access point (AP) and a station (STA) in a wireless-fidelity (WI-FI) system. The communication between the UE and the base station in the high-frequency wireless communication system can also be applied to the communication scenario. The above communication scenario will be described below with reference to FIGS. 4 and 5.

FIG. 4 shows a schematic architectural diagram of an application scenario according to an embodiment of the present application. As shown in FIG. 4, when the access point 1 and the station 2 perform data transmission, the access point 2 attempts to perform data transmission to the station 2. Before the access point 2 attempts to transmit data to the station 2, the access point 2 first needs to listen to the channel (listen before talk (LBT)) to determine whether the channel is idle. Since the access point 2 is located outside the coverage of the access point 1, it is impossible to know whether the data link of the access point 1 and the station 1 exists, and it may be determined that the channel is idle. While station 2 is located within the coverage of access point 1, it may be interfered by access point 1, so if access point 2 sends data to station 2, station 2 may receive incorrectly. In the scenario of Figure 4, access point 1 can be understood as a hidden node of access point 2. Currently, a handshake to send (RTS)/clear to send (CTS) handshake mechanism is introduced in the WIFI system, that is, the access point 2 sends the RTS to the site 2 before sending the data to the station 2. While the station 2 is aware of the link interference of the access point 1, and therefore may not reply to the CTS, the access point 2 can learn that the station 2 is interfered and cannot establish a data link with the station 2, thereby avoiding the occurrence of interference.

FIG. 5 shows a schematic architectural diagram of another application scenario according to an application embodiment. As shown in FIG. 5, for example, the basic network architecture of the high frequency wireless communication system may include a base station (eNodeB) 20 and at least one wireless terminal, such as User Equipment (UE), UE 10, UE 11, UE 12, UE. 13, UE 14, UE 15, UE 16 and UE 17. As shown in FIG. 5, the eNodeB 20 is configured to provide communication services for at least one of the UE 10 to the UE 17 and access the core network. Any one of the UE 10 to the UE 17 and the eNodeB 20 may include at least one antenna, and FIG. 5 is described by taking multiple antennas as an example, where multiple antennas may correspond to the same antenna port, or one antenna may correspond to one antenna port. . For any of the wireless terminals and eNodeB 20 of Figure 5, the communication signals between them need to be transmitted through the antenna. For example, signals of multiple beams may be transmitted or received between a base station and a UE through respective antennas. In the communication process of the high-frequency wireless communication system, in order to overcome the high path loss of the high frequency band, the physical layer needs to adopt a high-gain narrow beam antenna to improve the coverage of the communication link. In this process, the antenna may need to perform beam switching. For example, the antenna array is composed of N antenna elements, and each antenna element corresponds to a phase value (for example, a set of phase values corresponding to N antenna elements)

By changing

Different beams can be obtained, that is, each group of phase values corresponds to one beam. In the process of beam scanning by the antenna, each group of phase values of the N antenna elements corresponds to one beam, for example, beam 1, beam 2, beam 3 …Wait.

The base station 20 in FIG. 5 may be a base station in a high frequency wireless communication system or a communication device or network device supporting a high frequency wireless communication system. The network device may be a device for communicating with the terminal device, and the network device may be a global mobile communication GSM system or a base transceiver station (BTS) in code division multiple access CDMA, or may be a wideband code division multiple access WCDMA. The base station (NodeB, NB) in the system may also be an evolved base station (evolutional NodeB, eNB or eNodeB) in the LTE system, or may be a wireless control in a cloud radio access network (CRAN) scenario. , or the network device may be a relay station, an access point, an in-vehicle device, a wearable device, a base station gNB in a 5G mobile communication system, a base station in a future mobile communication system, or an access node in a WiFi system, and in a future 5G network. The network device in the network device or the network device in the future evolved PLMN network is not limited in this embodiment.

The user equipment (UE) in FIG. 5 may also be referred to as a mobile terminal, a mobile station (MS), a mobile terminal (MT), and the like. The terminal device can be a mobile phone, a tablet, a computer with wireless transceiver function, a virtual reality (VR) terminal device, an augmented reality (AR) terminal device, industrial control (industrial control) Wireless terminal, wireless terminal in self driving, wireless terminal in remote medical surgery, wireless terminal in smart grid, wireless in transport safety A terminal, a wireless terminal in a smart city, a wireless terminal in a smart home, and the like.

Base stations and user equipment can be deployed on land, indoors or outdoors, hand-held or on-board; they can also be deployed on the water; they can also be deployed on airborne aircraft, balloons and satellites. The application scenarios of the base station and the user equipment are not limited in the embodiment of the present application.

Communication between the base station and the user equipment and between the user equipment and the user equipment may be through a licensed spectrum, or through an unlicensed spectrum, or simultaneously through an authorized spectrum and an unlicensed spectrum. . The radio access network device and the terminal device and the terminal device and the terminal device can communicate through the spectrum below 6 GHz, or can communicate through the spectrum above 6 GHz, and can simultaneously use the spectrum below 6 GHz and the spectrum above 6 GHz.
