The embodiments of the present application relate to the field of mobile communication technologies, and in particular, to a method and apparatus for wireless communication, and a communication device.

Background technique

At present, the research of New Radio (NR) system mainly considers two frequency bands, namely frequency band 1 (Frequency range 1, FR1) and frequency band 2 (Frequency range 2, FR2). With the evolution of the NR system, a new frequency band, that is, a frequency band higher than FR1 and FR2, has also been studied. For the convenience of description, the new frequency band is called a high frequency frequency band.

The high-frequency frequency band includes licensed spectrum and unlicensed spectrum, wherein licensed spectrum may also be referred to as unshared spectrum, and unlicensed spectrum may also be referred to as shared spectrum. Because the frequency band is relatively high, the channel access method on the unlicensed spectrum on the high frequency band is different from the channel access method on the unlicensed spectrum on FR1/FR2. For the unlicensed spectrum on the high-frequency frequency band, there is no clear solution on how to support the channel access mode assisted by the receiving side.

high frequency

The research of the NR system mainly considers two frequency bands, namely FR1 and FR2, among which, the frequency domain ranges included in FR1 and FR2 are shown in Table 1 below.

Band Definition Corresponding frequency range FR1 410MHz–7.125GHz FR2 24.25GHz–52.6GHz

Table 1

With the evolution of the NR system, new frequency bands, that is, higher frequency bands than FR1 and FR2, have also begun to be studied. For the convenience of description, the new frequency band is called the high frequency frequency band. The high frequency frequency band can also be represented by FRX. It is understood that this band name should not constitute any qualification, for example, FRX may be FR3. The frequency domain range included by FRX is shown in Table 2 below.

high frequency Corresponding frequency range FRX 52.6GHz–71GHz

Table 2

FRX includes licensed spectrum and unlicensed spectrum, wherein licensed spectrum may also be called unshared spectrum or dedicated spectrum, and unlicensed spectrum may also be called shared spectrum.

Unlicensed spectrum is the spectrum allocated by countries and regions that can be used for radio equipment communication. This spectrum is generally considered to be shared spectrum, that is, communication equipment in different communication systems can meet the regulatory requirements set by the country or region on the spectrum. To use this spectrum, there is no need to apply for an exclusive spectrum license from the government.

In order to enable various communication systems that use unlicensed spectrum for wireless communication to coexist amicably on this spectrum, some countries or regions have stipulated regulatory requirements that must be met when using unlicensed spectrum. For example, a communication device follows the "Listen Before Talk (LBT)" principle, that is, before a communication device transmits a signal on an unlicensed spectrum channel, it needs to perform channel listening first, and only when the channel listening result is a channel The communication device can send signals only when it is idle; if the channel detection result of the communication device on the channel of the unlicensed spectrum is that the channel is busy, the communication device cannot send signals. For another example, in order to ensure fairness, in one transmission, the duration of signal transmission by the communication device using the channel of the unlicensed spectrum cannot exceed a certain duration. For another example, in order to avoid that the power of the signal transmitted on the channel of the unlicensed spectrum is too large and affects the transmission of other important signals on the channel, the communication device needs to follow the maximum power spectrum when using the channel of the unlicensed spectrum for signal transmission. Density limit. It should be noted that in some countries or regions, there is no LBT requirement for the unlicensed spectrum included in the FRX frequency band.

The subcarrier spacing of FRX may be larger than that of FR2, and the current candidate subcarrier spacing includes at least one of the following: 240 kHz, 480 kHz, and 960 kHz. As an example, the corresponding parameter sets (Numerology) under these candidate subcarrier intervals are shown in Table 3 below. NCP in Table 3 refers to a normal cyclic prefix (Normal Cyclic Prefix), and ECP refers to an extended cyclic prefix (Extended Cyclic Prefix).

Concepts related to shared spectrum

Maximum Channel Occupancy Time (MCOT): refers to the maximum length of time allowed to use the channel for signal transmission after successful channel sensing on the channel of the shared spectrum.

Channel Occupancy Time (COT): refers to the length of time that the channel is used for signal transmission after successful channel detection on the channel of the shared spectrum. length of time. Wherein, the signal occupation of the channel may be continuous or discontinuous within the time length, and the time length includes the total time for signal transmission by the device initiating the channel occupation and the device sharing the channel occupation.

Channel occupation time of network equipment (gNB/eNB-initiated COT): also known as COT initiated by network equipment, it refers to a channel occupation time obtained by network equipment after successful channel detection on the channel of the shared spectrum. The COT initiated by the network device can not only be used for transmission by the network device, but also can be used for transmission by the terminal device under certain conditions.

UE-initiated COT (UE-initiated COT): Also known as COT initiated by the terminal device, it refers to the channel occupancy time obtained by the terminal device after successful channel detection on the channel of the shared spectrum. The COT initiated by the terminal device can not only be used for transmission by the terminal device, but also can be used for transmission by the network device under certain conditions.

Downlink transmission opportunity (DL transmission burst): refers to a group of downlink transmissions (that is, including one or more downlink transmissions) performed by network equipment, and the group of downlink transmissions is continuous transmission (that is, there is no gap between multiple downlink transmissions), or the There is a gap in the group downlink transmission but the gap is less than or equal to a preset value, for example, on the FR1 frequency band, the preset value is 16 microseconds. If the gap between two downlink transmissions performed by the network device is greater than the preset value of 16 microseconds, the two downlink transmissions are considered to belong to two downlink transmission opportunities.

Uplink transmission opportunity (UL transmission burst): refers to a group of uplink transmissions performed by terminal equipment (that is, including one or more uplink transmissions), the group of uplink transmissions is continuous transmission (that is, there is no gap between multiple uplink transmissions), or the There is a gap in the group uplink transmission but the gap is less than or equal to a preset value, for example, in the FR1 frequency band, the preset value is 16 microseconds. If the gap between two uplink transmissions performed by the terminal device is greater than the preset value of 16 microseconds, the two uplink transmissions are considered to belong to two uplink transmission opportunities.

It should be understood that in the FRX frequency band, the above-mentioned preset value may be other values, for example, 8 microseconds. This application is not limited to this.

Channel Detection Success: Also known as LBT Success or Channel Detection Idle. For example, the energy detection in the listening time slot performed on the channel is below the energy detection threshold.

Channel Detection Failed: Also known as LBT Failure or Channel Detection Busy. For example, the energy detection in the listening time slot of the channel is higher than or equal to the energy detection threshold.

Channel access mode assisted by receiving side

The channel access method assisted by the receiving side is a channel access method similar to the Request To Send/Clear To Send (RTS/CTS) mechanism of the Wi-Fi system. as shown in picture 2,

1. Before the network device transmits, it first sends an RTS signal, and the RTS signal is used to inquire whether the terminal device is ready to receive data.

2. Case 1: After receiving the RTS signal, if the channel detection is successful, the terminal device can send a CTS signal to the network device. The CTS signal is used to inform the network device that the terminal device is ready for data reception. Optionally, The CTS signal carries the interference measurement result of the terminal device; the network device can perform downlink transmission to the terminal device after receiving the CTS signal. or,

Case 2: If the terminal device does not receive the RTS signal or the terminal device receives the RTS signal but cannot send the CTS signal due to channel detection failure, the terminal device will not send the CTS signal to the network device; the network device does not receive the CTS signal from the terminal device. In the case of , the downlink transmission to the terminal equipment can be abandoned.

Channel access corresponding to unlicensed spectrum on high frequency bands

On FRX, for countries and regions with LBT requirements, the channel access mode (ie LBT mode) can include omnidirectional channel access mode (ie omnidirectional LBT), directional channel access mode (ie directional LBT), receiving side Auxiliary channel access mode (ie receiving side auxiliary LBT) and channel access mode without channel detection (ie without LBT) and so on. Among them, the channel access method without channel detection may also need to be limited by certain conditions, such as automatic transmit power control (Automatic Transmit Power Control, ATPC), DFS, long-term interference detection or other interference cancellation mechanisms. In addition, it is also possible to switch between the channel access mode with channel detection and the channel access mode without channel detection. For countries and regions without LBT requirements, it is also necessary to consider whether to introduce certain conditions, such as whether to apply ATPC, DFS, long-term interference detection, limit a certain duty cycle (duty cycle), limit a certain transmit power, limit MCOT, etc. Wait.

Due to the relatively high frequency band, the channel access method on the unlicensed spectrum on the FRX is different from the channel access method on the unlicensed spectrum on the FR1 frequency band. For example, in the FRX frequency band, a channel access method based on transceiver interaction, which is also called a receiving-side auxiliary channel access method, may be introduced. If the receiver-assisted channel access mode is to be supported on the unlicensed spectrum on the FRX, a clear scheme is required for how to send the request-to-send information. To this end, the following technical solutions of the embodiments of the present application are proposed, and the technical solutions of the embodiments of the present application can be applied to, but not limited to, unlicensed spectrum on FRX.
