Before introducing the technical solution of this application, some background technical knowledge involved in this application will be introduced. The following related technologies may be optionally combined with the technical solutions of the embodiments of the present application as optional solutions, and all of them belong to the protection scope of the embodiments of the present application. The embodiment of the present application includes at least part of the following contents.

1. High-frequency related background

With the evolution of the NR system, the research of the NR system can include new frequency bands such as 52.6GHz–71GHz or 71GHz–114.25GHz. The new frequency band may include licensed spectrum or unlicensed spectrum. In other words, the new frequency band includes dedicated spectrum and shared spectrum. The sub-carrier spacing considered in the new frequency band may be larger than the sub-carrier spacing supported by the existing NR system, for example, the sub-carrier spacing may be 480 kHz or 960 kHz. Specifically, the subcarrier spacing supported by the new frequency band includes at least one of 120 kHz, 480 kHz, and 960 kHz.

2. Unlicensed spectrum (shared spectrum)

The unlicensed spectrum is the spectrum allocated by the country and region that can be used for radio device communication. This spectrum is usually considered a shared spectrum, that is, communication devices in different communication systems can be used as long as they meet the regulatory requirements set by the country or region on the spectrum. To use this spectrum, there is no need to apply to the government for exclusive spectrum authorization.

In order to allow various communication systems that use unlicensed spectrum for wireless communication to coexist friendly on this spectrum, some countries or regions have stipulated regulatory requirements that must be met when using unlicensed spectrum. For example, communication equipment follows the principle of "Listen Before Talk (LBT)", that is, before the communication equipment transmits signals on the channel of the unlicensed spectrum, it needs to perform channel detection first, and only when the channel detection result is that the channel The communication device can only send signals when it is idle; if the channel detection result of the communication device on an unlicensed spectrum channel shows that the channel is busy, the communication device cannot send signals. In order to ensure fairness, in a transmission, the duration of signal transmission by the communication device using the channel of the unlicensed spectrum cannot exceed the Maximum Channel Occupancy Time (MCOT).

In the high-frequency band, both licensed spectrum and unlicensed spectrum are included. On the unlicensed spectrum included in the high-frequency band, for countries and regions that have LBT requirements, the LBT method (that is, the channel access method) can include omnidirectional LBT, directional LBT, receiving-side auxiliary LBT and no LBT. . Among them, for the channel access method without LBT, it may also need to be limited by certain conditions such as ATPC (Automatic Transmit Power Control, automatic transmission power control), DFS (Dynamic Frequency Selection, dynamic frequency selection), long-term interference detection or other Interference cancellation mechanism, etc. In addition, it is also possible to switch between channel access with LBT and channel access without LBT. Wherein, in some cases, for directional LBT, the beam direction associated with directional LBT can be determined by QCL relationship or spatial filter.

For countries and regions without LBT requirements, it is also necessary to consider whether to introduce certain conditions, such as whether to apply DFS, apply ATPC, apply long-term interference detection, limit a certain duty cycle (duty cycle), limit a certain transmit power, limit MCOT etc.

3. QCL relationship in NR system

Quasi Co-Location (QCL) means that the large-scale parameters of the channel experienced by symbols on one antenna port can be inferred from the channel experienced by symbols on another antenna port. The large-scale parameters may include delay spread, average delay, Doppler spread, Doppler frequency shift, average gain, and spatial reception parameters.

In the NR system, considering the possible QCL relationship between various reference signals, the above-mentioned channel large-scale parameters can be divided into different QCL types, which is convenient for the system to configure according to different scenarios where the terminal equipment is located. The definitions of different QCL type configurations are as follows:

'QCL-TypeA': {Doppler shift (Doppler shift), Doppler spread (Doppler spread), average delay (average delay), delay spread (delay spread)};

'QCL-TypeB': {Doppler shift (Doppler shift), Doppler spread (Doppler spread)};

'QCL-TypeC': {Doppler shift (Doppler shift), average delay (average delay)};

'QCL-TypeD': {Spatial Rx parameter}.

Before the RRC signaling configuration (such as the initial access stage), the terminal device has the system default QCL relationship from SSB (Synchronization Signal and PBCH block, synchronization signal and PBCH block) to DMRS (Demodulation Reference Signal, demodulation reference signal) , the terminal device can obtain the Doppler frequency shift, Doppler spread, average delay, delay spread and spatial reception parameters of the channel from the SSB signal through the QCL relationship between the SSB and the DMRS to adjust the filter parameters of the DMRS channel estimator, In this way, PDCCH (Physical Downlink Control Channel, physical downlink control channel) and PDSCH (Physical Downlink Shared Channel, physical downlink shared channel) are received. The above QCL relationship between SSB and DMRS can be expressed as:

SSB→DMRS, including Doppler frequency shift, Doppler spread, average delay, delay spread and spatial reception parameters.

After the RRC signaling configuration (for example, the RRC connected state stage), the QCL relationship between the reference signals includes at least one of the following situations:

SSB→TRS (Tracking Reference Signal, tracking reference signal), including Doppler frequency shift, average delay, space receiving parameters; or, corresponding to 'QCL-TypeC'+'QCL-TypeD'.

TRS→CSI-RS (Channel State Information-Reference Signal, channel state information reference signal) for BM (Beam Management, beam management), including Doppler frequency shift, Doppler spread, average delay, delay spread ; Or, corresponding to 'QCL-TypeA'+'QCL-TypeD'.

TRS→CSI-RS for CSI (Channel State Information, channel state information), including Doppler frequency shift, Doppler spread, average delay, delay spread; or, corresponding to 'QCL-TypeA'.

TRS→DMRS for PDSCH, including Doppler frequency shift, Doppler spread, average delay, delay spread; or, corresponding to 'QCL-TypeA'+'QCL-TypeD'.

SSB→CSI-RS for BM, including Doppler frequency shift, average delay, and spatial reception parameters; or, corresponding to 'QCL-TypeC'+'QCL-TypeD'.

SSB → CSI-RS for CSI, including spatial reception parameters; or, corresponding to 'QCL-TypeD'.

SSB→DMRS for PDCCH (before TRS configuration), including Doppler frequency shift, Doppler spread, average delay, delay spread, spatial reception parameters; or, corresponding to 'QCL-TypeA'+'QCL-TypeD '.

SSB→DMRS for PDSCH (before TRS configuration), including Doppler frequency shift, Doppler spread, average delay, delay spread, spatial reception parameters; or, corresponding to 'QCL-TypeA'+'QCL-TypeD '.

CSI-RS for BM → DMRS for PDCCH, including spatial reception parameters; or, corresponding to 'QCL-TypeD'.

CSI-RS for BM → DMRS for PDSCH, including spatial reception parameters; or, corresponding to 'QCL-TypeD'.

CSI-RS for CSI → DMRS for PDSCH, including Doppler frequency shift, Doppler spread, average delay, delay spread, spatial reception parameters; or, corresponding to 'QCL-TypeA'+'QCL- Type D'. Among them, QCL parameters cannot be directly obtained from CSI-RS for CSI.

CSI-RS for BM → CSI-RS for TRS/BM/CSI, including spatial reception parameters; or, corresponding to 'QCL-TypeD'.

For different types of reference signals, the acquisition of QCL reference includes the following situations:

Configured by RRC, such as periodic CSI-RS or TRS;

Through RRC configuration, activated by MAC CE (MAC Control Element, media access layer control unit) (abbreviated as MAC CE-based indication), for example, through MAC CE indication to activate or deactivate periodic CSI-RS or TRS, or PDCCH DMRS;

Through RRC configuration, activated by MAC CE, and indicated by DCI (abbreviated as DCI-based indication), such as aperiodic CSI-RS or TRS, or DMRS of PDSCH.

It should be noted that the QCL reference of the DMRS of the PDSCH may also be activated by the MAC CE through the RRC configuration.

The RRC configuration includes: the RRC configuration includes QCL information, and the QCL information is used to determine the QCL reference of the target reference signal.

The MAC-CE-based indication includes: RRC configures a set of TCI (Transmission Configuration Indicator, transmission configuration indication) states, and each TCI state corresponds to a QCL reference. Select a TCI state from the group of TCI states through the MAC CE, and use it as the QCL reference of the target reference signal.

The DCI-based indication includes: RRC configures M TCI states, and each TCI state corresponds to a QCL reference. Select up to 8 TCI states from the M TCI states through the MAC CE to correspond to the 3-bit TCI indication information in the DCI, wherein, if the value of M is less than or equal to 8, the M TCI states and the TCI in the DCI corresponding to the instruction information. Select a TCI state from the TCI states corresponding to the TCI indication information in the DCI through the DCI, and use it as the QCL reference of the target reference signal.

The TCI status contains the information of the QCL reference. Each TCI state may include at most two downlink reference signals, serving as at most two types of reference sources respectively. Specifically, the TCI state ID is used to identify a TCI state;

QCL information 1;

QCL information2.

Among them, a QCL information contains the following information:

QCL type configuration, which can be one of QCL type A, QCL type B, QCL type C, and QCL type D;

The QCL reference signal configuration includes the cell ID where the reference signal is located, the BWP (Bandwidth Part, partial bandwidth) ID, and the identifier of the reference signal (which can be a CSI-RS resource ID or SSB index).

Among them, the QCL type of at least one of the QCL information in QCL information 1 and QCL information 2 must be one of typeA, typeB, and typeC, and the QCL type of the other QCL information (if configured) must be QCL type D.

In a high-frequency system, when using directional LBT, it is generally required that the beamforming used in channel detection needs to cover the corresponding beamforming in signal transmission. In other words, the terminal device can use one or more directions to detect the channel. If the channel detection using the LBT based on the first direction successfully obtains the first COT, then the first COT has an association relationship with the first direction, for example It is necessary to use the beam direction corresponding to the first direction (or in other words, the spatial filter corresponding to the first direction) to perform physical channel or signal transmission in the first COT. Correspondingly, if the DCI format 2_0 is configured in the system, the DCI format 2_0 also needs to be indicated based on the first direction. For example, if the DCI format 2_0 includes indication information such as remaining COT length, available RB (Resource Block, resource block) set, and search space set group (Search space set group) switching flag, then the remaining COT length, available RB set, search The space aggregation group switching flag is associated with the first direction.

In the related art, the QCL information of the periodic reference signal is configured by RRC. In a high-frequency system, for a preconfigured periodic physical channel or signal located in the first COT, there may be a situation that its QCL information does not correspond to the first direction. In this case, how to process the periodic physical channel or reference signal is a problem to be solved.

In the technical solution provided by this application, for high-frequency systems, the QCL information of periodic physical channels or reference signals is configured by RRC. When the first COT to which the resources used to transmit periodic physical channels or reference signals belongs is based on When the channel access method (such as directional LBT) is acquired, this application proposes to determine whether to perform the periodic The transmission of permanent physical channels or reference signals can ensure the fairness of resource usage on unlicensed spectrum.
