Background
Research on New Radio (NR) systems currently mainly considers two Frequency bands, namely Frequency band 1 (f 1) and Frequency band 2 (f 2).

High Frequency
The NR system is studied mainly considering two frequency bands, FR1 and FR2, respectively, wherein FR1 and FR2 include the frequency domain ranges shown in table 1 below.
Frequency band definition Corresponding frequency range
FR1 410MHz–7.125GHz
FR2 24.25GHz–52.6GHz
TABLE 1
As the NR system evolves, a new frequency band, i.e., a frequency band higher than FR1 and FR2, is also being studied, and for convenience of description, the new frequency band is referred to as a high frequency band, which may also be denoted by FRX, it should be understood that the frequency band name should not constitute any limitation, and for example, FRX may be FR3. The frequency domain ranges included in FRX are shown in table 2 below.
High Frequency Corresponding frequency range
FRX 52.6GHz–71GHz
TABLE 2
The FRX includes a licensed spectrum and an unlicensed spectrum, where the licensed spectrum may also be referred to as an unshared spectrum or a dedicated spectrum, and the unlicensed spectrum may also be referred to as a shared spectrum.
Unlicensed spectrum is a nationally and regionally divided spectrum that can be used for radio communications and is generally considered to be a shared spectrum, i.e., communication devices in different communication systems can use the spectrum as long as the regulatory requirements set by the country or region on the spectrum are met, without requiring a proprietary spectrum grant to be applied to the government.
In order for individual communication systems using unlicensed spectrum for wireless communication to co-exist friendly over that spectrum, some countries or regions specify regulatory requirements that must be met using unlicensed spectrum. For example, the communication device follows the principle of listen before talk (Listen Before Talk, LBT), that is, the communication device needs to perform channel interception before performing signal transmission on a channel of an unlicensed spectrum, and the communication device can perform signal transmission only when the channel interception result is that the channel is idle; if the channel listening result of the communication device on the channel of the unlicensed spectrum is that the channel is busy, the communication device is unable to signal. For another example, in order to ensure fairness, the communication device cannot use the unlicensed spectrum channel for signal transmission for more than a certain length of time in one transmission. As another example, to avoid that the power of a signal transmitted on a channel of unlicensed spectrum is too high, affecting the transmission of other important signals on that channel, a communication device needs to follow a limit of not exceeding the maximum power spectral density when using the channel of unlicensed spectrum for signal transmission. It should be noted that in some countries or regions, there is no requirement for LBT for unlicensed spectrum included in the FRX band.
The subcarrier spacing of FRX may be greater than the subcarrier spacing of FR2, with the current candidate subcarrier spacing comprising at least one of the following: 240kHz, 480kHz, 960kHz. As an example, the corresponding parameter sets (Numerology) at these candidate subcarrier spacings are shown in table 3 below. NCP in table 3 refers to the normal cyclic prefix (Normal Cyclic Prefix) and ECP refers to the extended cyclic prefix (Extended Cyclic Prefix).
TABLE 3 Table 3
Shared spectrum related concepts
Maximum channel occupancy time (Maximum Channel Occupancy Time, MCOT): refers to the maximum length of time that channel detection (channel sensing) on a channel sharing the spectrum will allow for signal transmission using that channel.
Channel occupancy time (Channel Occupancy Time, COT): the time length of signal transmission using the channel after the channel detection on the channel of the shared spectrum is successful may also be considered as the time length of occupying the channel after the channel detection on the channel of the shared spectrum is successful. Wherein the signal occupying channel may be continuous or discontinuous for the length of time, which includes the total time for signal transmission by the device initiating channel occupancy and the device sharing channel occupancy.
Channel occupancy time (gNB/eNB-initiated COT) of the network device: also referred to as network device initiated COT, refers to the primary channel occupation time obtained by a network device after successful channel detection on a channel sharing a spectrum. The COT initiated by the network device can be used for transmission by the network device and can also be used for transmission by the terminal device under the condition that a certain condition is met.
Channel occupation time (UE-initiated COT) of terminal device: the COT initiated by the terminal equipment refers to the primary channel occupation time obtained by the terminal equipment after successful channel detection on the channels sharing the frequency spectrum. The COT initiated by the terminal device can be used for transmission by the terminal device and can also be used for transmission by the network device under the condition that a certain condition is met.
Downlink transmission opportunity (DL transmission burst): refers to a set of downlink transmissions by a network device (i.e., including one or more downlink transmissions), which are either continuous transmissions (i.e., no gaps between the downlink transmissions), or which have gaps therein but less than or equal to a predetermined value, e.g., 16 microseconds over the FR1 band. If the gap between two downlink transmissions by the network device is greater than the preset value of 16 microseconds, then the two downlink transmissions are considered to belong to two downlink transmission opportunities.
Uplink transmission opportunity (UL transmission burst): a group of uplink transmissions by the terminal device (i.e. including one or more uplink transmissions), where the group of uplink transmissions is a continuous transmission (i.e. there is no gap between the uplink transmissions), or where the group of uplink transmissions has a gap but the gap is less than or equal to a preset value, e.g. 16 microseconds in the FR1 band. If the gap between two uplink transmissions by the terminal device is greater than the preset value by 16 microseconds, then the two uplink transmissions are considered to belong to two uplink transmission opportunities.
It should be appreciated that in the FRX band, the above-mentioned preset value may be other values, for example, 8 microseconds. The application is not limited in this regard.
Channel detection succeeds: also known as LBT success or channel detection idle. For example, the energy detection in the listening slot for the channel is below the energy detection threshold.
Channel detection failure: also known as LBT failure or busy channel detection. For example, the detection of energy in a listening slot for a channel is greater than or equal to an energy detection threshold.
Channel access mode assisted by receiving side
The receiver-side assisted channel access method is a channel access method similar To a Request To Send/Clear To Send (RTS/CTS) mechanism of a Wi-Fi system. As shown in the figure 2 of the drawings,
1. The network device sends an RTS signal before transmitting, which is used to ask the terminal device if it is ready to receive data.
2. Case one: after the terminal equipment receives the RTS signal, if the channel detection is successful, a CTS signal can be sent to the network equipment, wherein the CTS signal is used for informing the network equipment that the terminal equipment is ready for data reception, and optionally, the CTS signal carries an interference measurement result of the terminal equipment; after receiving the CTS signal, the network device may perform downlink transmission to the terminal device. Or alternatively, the process may be performed,
and a second case: if the terminal equipment does not receive the RTS signal or the terminal equipment receives the RTS signal but cannot send the CTS signal due to the failure of channel detection, the terminal equipment does not send the CTS signal to the network equipment; the network device may forego downlink transmission to the terminal device without receiving the CTS signal of the terminal device.
Channel access for unlicensed spectrum on high frequency band
In FRX, for countries and regions where LBT is required, channel access manners (i.e., LBT manner) may include an omni-directional channel access manner (i.e., omni-directional LBT), a directional channel access manner (i.e., directional LBT), a receiving-side assisted channel access manner (i.e., receiving-side assisted LBT), and a channel access manner that does not perform channel detection (i.e., does not perform LBT). For the channel access mode without channel detection, certain conditions, such as automatic transmit power control (Automatic Transmit Power Control, ATPC), DFS, long-term interference detection or other interference cancellation mechanisms, etc., may also need to be restricted. In addition, the switching can be performed between the channel access mode for channel detection and the channel access mode for no channel detection. For countries and regions where no LBT requirements are present, it is also considered whether certain conditions are to be introduced, such as whether ATPC, DFS, long-term interference detection, limitation of certain duty cycle, limitation of certain transmit power, limitation of MCOT, etc. need to be applied.
Because the frequency band is relatively high, the channel access mode on the unlicensed spectrum on the FRX is different from the channel access mode on the unlicensed spectrum on the FR1 frequency band. For example, a channel access mode based on the transceiving interaction, also called a receiving side auxiliary channel access mode, may be introduced in the FRX frequency band. If the receiver-side assisted channel access mode is to be supported on unlicensed spectrum on FRX, an explicit scheme is required for how to send the request-to-send information. Therefore, the following technical solutions of the embodiments of the present application are provided, and the technical solutions of the embodiments of the present application may be applied, but are not limited to, to unlicensed spectrum on FRX.
In order to facilitate understanding of the technical solution of the embodiments of the present application, the technical solution of the present application is described in detail below through specific embodiments. The above related technologies may be optionally combined with the technical solutions of the embodiments of the present application, which all belong to the protection scope of the embodiments of the present application.
