Technical field

Background technique

Unlicensed spectrum is a spectrum that can be used for radio equipment communications divided by countries and regions. This spectrum is usually considered to be a shared spectrum, that is, communication devices in different communication systems as long as they meet the regulatory requirements set by the country or region on the spectrum. To use this spectrum, it is not necessary to apply for a proprietary spectrum authorization from the government.

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 the legal requirements that must be met when using unlicensed spectrum. For example, communication equipment follows the "Listen Before Talk (LBT)" principle, that is, the communication equipment needs to perform channel detection before sending signals on channels of unlicensed spectrum, only when the channel detection result is channel When it is idle, the communication device can send signals; 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.

In the unlicensed spectrum, the LBT method can be the channel access method of frame-based equipment (FBE). The frame structure appears periodically. A frame structure includes channel occupancy time (COT). ),free time. The communication device monitors the channel during the idle time. If the channel monitoring succeeds, the COT in the next fixed frame period can be used to transmit signals; if the channel monitoring fails, the COT in the next fixed frame period cannot be used to transmit signals. How to receive the remaining system information (System Information, SI) in the NR-U (NR-based access to unlicensed spectrum, NR-U) system under the channel access mode of FBE is a problem that needs to be solved urgently.

In addition, the character "/" in this text generally indicates that the associated objects before and after are in an "or" relationship.

The method in the embodiments of the present application can be applied to unlicensed spectrum communication, and can also be applied to other communication scenarios, such as a licensed spectrum communication scenario.

Unlicensed spectrum is the spectrum that can be used for radio equipment communication divided by the country and region. This spectrum can be considered as a shared spectrum, that is, communication devices in different communication systems can meet the regulatory requirements set by the country or region on the spectrum. To use this spectrum, it is not necessary to apply for a proprietary spectrum authorization from the government. In order to allow various communication systems that use unlicensed spectrum for wireless communication to coexist friendly on this spectrum, communication devices can follow the principle of Listen Before Talk (LBT) when communicating on unlicensed spectrum, that is, Before the communication device transmits signals on the channels of the unlicensed spectrum, it needs to perform channel detection (or called channel detection) first. Only when the channel detection result is that the channel is idle, the communication device can transmit signals; if the communication device is in The result of channel sensing on the unlicensed spectrum is that the channel is busy, and signal transmission cannot be performed. Optionally, the bandwidth of the LBT is 20 MHz, or an integer multiple of 20 MHz.

The LBT method includes two types from the perspective of network deployment. One is the load-based equipment (LBE) channel access method, that is, the communication device can monitor the channel on the unlicensed spectrum after the service arrives, and After the channel monitoring is successful, the signal transmission starts. The other is a channel access method based on frame-based equipment (FBE). Figure 2 is a schematic diagram of an FBE-based channel access method provided by an embodiment of the present application. As shown in Figure 2, in the FBE channel access method, the frame structure appears periodically, and the period length does not exceed a preset value. For example, 200ms, a frame structure includes COT (the length does not exceed 95% of the fixed frame period) and idle time (the length is at least 5% of the channel occupation time, the minimum value is 100us, and it is located at the end of the fixed frame period). The communication device performs clear channel assessment (CCA), and the communication device monitors the channel during the idle period (Idle Period). If the channel monitoring is successful, the channel occupation time in the next fixed frame period can be used for transmission Signal; if the channel monitoring fails, the channel occupancy time in the next fixed frame period cannot be used to transmit the signal. In other words, the channel resources that the communication device can use for service transmission appear periodically.

In the LBE-based NR-U system, the initial access process of the terminal device can be completed through the Discovery Reference Signal (DRS). The DRS includes a synchronization signal block (Synchronization Signal/PBCH Block, SSB or SS/PBCH Block), and the DRS is sent in the DRS window. The DRS window appears periodically. There can be multiple candidate positions for transmitting the SSB in the DRS window. When the network device sends the SSB in the DRS window, it can make multiple LBT attempts, and can pass the multiple candidates after the LBT succeeds. At least one candidate position among the positions performs SSB transmission. Wherein, the quasi-co-located (QCL) assumption (or QCL relationship) between the multiple SSB candidate positions is determined by the Q value, for example, the index of the multiple SSB candidate positions modulo Q The SSBs transmitted at the SSB candidate positions with the same value can be considered to have the same QCL hypothesis. The Q value can be preset or indicated by the base station. Optionally, if the Q value is indicated, the Q value may be indicated by the base station through system information such as master information block (Master Information Block, MIB) or system information block (System Information Block, SIB), or the Q value is also indicated. It may be indicated by the base station through a physical broadcast channel (Physical broadcast channel, PBCH). Optionally, the Q value can be one of 1, 2, 4, or 8. As an example, assuming that the Q value is 4, then the first SSB candidate position, the fifth SSB candidate position, the ninth SSB candidate position, etc., the SSBs transmitted at the candidate positions with the same value after modulo Q have the same QCL hypothesis.

For example, FIG. 3 is a schematic diagram of SSB candidate positions in a DRS window provided by an embodiment of the present application. As shown in Example 1 in FIG. 3, the set of SSB candidate positions in the DRS window includes 20 SSB candidate positions, the Q value is 4, and the SSB candidate positions with the same QCL hypothesis are represented by the same QCL label. Specifically, the terminal device may assume that the SSBs sent on the SSB candidate locations with the same QCL label have the same QCL relationship, or that if the network device sends the SSB on the SSB candidate locations with the same QCL label, then the network device should use the same Beam.

The SSB to be sent includes at least one SSB in the SSB set. For example, the SSB set includes SSB0, 1, 2, 3, the SSB candidate position with QCL label 0 is used for sending SSB0, the SSB candidate position with QCL label 1 is used for sending SSB1, and the SSB candidate position with QCL label 2 is used for sending SSB2, QCL SSB candidate position number 3 is used to send SSB3. The SSB to be sent includes at least one SSB in the SSB set. For example, assuming that the SSB to be transmitted includes SSB0, SSB2, and SSB3, the SSB candidate positions labeled 0, 2, and 3 in Example 1 may all be used for SSB transmission.

In different DRS windows, the base station may select candidate positions for obtaining the channel use right from among the SSB candidate positions in the DRS window according to the LBT result for SSB transmission. During the initial access process of the terminal device, if the SSB is detected, the terminal device can determine the control resource set (Control-resource set, CORESET) of the Type0-PDCCH common search space (CSS) set according to the MIB in the PBCH The PDCCH transmitted through the resources in the control resource set can be used to schedule the PDSCH carrying the remaining minimum system information (Remaining Minimum System Information, RMSI). Therefore, the terminal device can receive the corresponding RMSI information according to the SSB. Among them, RMSI can also be considered as System Information Block 1 (System Information Block 1, SIB1).

In the LBE-based NR-U system, when there are multiple SSB candidate positions in the DRS window, each SSB candidate position can be associated with a control resource set used to transmit RMSI. In this case, the control resource set used to transmit RMSI may also have multiple candidate positions. When receiving the RMSI, the terminal device may perform combined detection on the RMSI having a QCL relationship, for example, according to the Q value.

In the FBE-based NR-U system, since the frame structure appears periodically, if the LBT is successful, the channel occupation time in the next fixed frame period can be used to transmit signals, or in other words, the SSB or SSB in the fixed frame period DRS must be transmitted. In this case, multiple SSB candidate positions may not be included in the DRS window. For example, whether the SSB can be sent at the SSB candidate position is determined according to whether the base station obtains the channel use right in the fixed frame period where the SSB candidate position is located. Therefore, optionally, in this case, the Q value may not be required to determine the QCL hypothesis between multiple SSB candidate positions, or the base station does not need to indicate the Q value, or the Q value indicated by the base station is a special state, such as The reserved state, or the Q value may be a preset value, for example, the Q value is preset to the maximum value or the minimum value in the value range.

For example, as shown in Example 2 in Figure 3, the set of SSB candidate positions in the DRS window includes 4 SSB candidate positions, and the value of Q is preset to 8. Therefore, it can be considered that one SSB includes 1 candidate position in the DRS window. . The terminal device may assume that the SSBs sent at these SSB candidate positions do not have the same QCL relationship, or in other words, if the network device sends the SSB at different SSB candidate positions, the network device may use different beams.

Similarly, the SSB to be transmitted includes at least one SSB in the SSB set. For example, the SSB set includes SSB0, 1, 2, 3, the SSB candidate position marked 0 in Example 2 is used to send SSB0, the SSB candidate position marked 1 is used to transmit SSB1, and the SSB candidate position marked 2 is used to transmit SSB2, the SSB candidate position labeled 3 is used to send SSB3. Assuming that the SSB to be transmitted includes SSB0, SSB2, and SSB3, the SSB candidate positions labeled 0, 2, and 3 in Example 2 can be used for SSB transmission when the network device obtains the channel usage right of a fixed frame period.

In the FBE-based NR-U system, each SSB candidate position can also be associated with a set of control resources used to transmit RMSI. When a certain SSB to be sent in the DRS window has only one SSB candidate position, in this case, the control resource set used to transmit the RMSI corresponding to the SSB also has only one candidate position. When the terminal device receives the RMSI, it may not perform the combined detection of the RMSI according to the Q value.

However, in the initial access phase, when the terminal device detects the SSB, it does not know whether the current system belongs to the channel access mode of LBE or FBE. Therefore, when receiving RMSI, even for NR-U under FBE The system will still try to detect multiple RMSI control resource sets, for example, combine and detect RMSIs with QCL relationships based on the Q value, thereby increasing the complexity of system detection. This application mainly considers the enhancement of the sending and receiving methods of system information under the FBE structure.

Based on the schematic diagram of the communication system shown in FIG. 1, please refer to FIG. 4.

Optionally, the first indication information is carried in the MIB, including: the first indication information multiplexes the common subcarrier spacing subCarrierSpacingCommon command field in the MIB. This is mainly because, in the NR-U system, the subcarrier spacing of the control resource set of the SSB and Type0-PDCCH CSS set on the same carrier is always the same, so this information field may not be used to indicate the subcarrier spacing. Correspondingly, in the NR-U system, this information field can be multiplexed to indicate that the device type of the network device is FBE or LBE.

Optionally, the first indication information carried in the PBCH includes: multiplexing the first indication information in one or more bits of a designated position in the PBCH, wherein the designated position includes at least:

Optionally, the physical downlink control channel PDCCH in the Type0-PDCCHCSS set is used to schedule the transmission of the system information, and the system information is RMSI.

In a specific implementation manner, the second indication information indicates the Q value, and the first indication information is the first information state of the second indication information. For example, the value of Q includes 1, 2, 4, and 8, which can be indicated by 2 bits, as shown in Table 1 below. Wherein, the first information status is that the 2-bit status is "11", or in other words, when the information status of Q is "11", it means that the device type of the current network device may be FBE.

For example, the value of Q includes 2, 4, and 8, which can be indicated by 2 bits, as shown in Table 2 below. Wherein, the first information status is that the 2-bit status is "11", or in other words, when the information status of Q is "11", it means that the device type of the current network device is FBE.

In a specific implementation manner, the second indication information is used to configure the control resource set of the Type0-PDCCH common search space CSS set, and the first indication information may be at least one configuration indicated by the second indication information. For example, the second indication information is used to indicate N types of control resource set configurations, where M1 configurations in the N control resource set configurations are applied to LBE, and M2 configurations in the N control resource set are applied to FBE. The terminal device can determine whether the network device is an FBE or an LBE according to the received second indication information.

Optionally, the obtaining the target downlink resource according to the first indication information includes: when the device type of the network device is determined to be FBE according to the first indication information, the target downlink resource is the first downlink resource corresponding to the FBE; or When it is determined that the device type of the network device is LBE according to the first indication information, the target downlink resource is the second downlink resource corresponding to the LBE; wherein, the first downlink resource and the second downlink resource are different.

Optionally, the first downlink resource is not determined according to the Q value. Optionally, after the terminal device determines that the network device is an FBE according to the first indication information, the terminal device may not perform the RMSI combined detection based on the Q value when receiving the RMSI, or the terminal device may assume a certain value in the DRS window. Each SSB to be sent has only one SSB candidate position, and the control resource set used to transmit the RMSI corresponding to the SSB also has only one candidate position.

Optionally, the second downlink resource is determined according to the Q value. Optionally, after the terminal device determines that the network device is an LBE according to the first indication information, when receiving the RMSI, the terminal device may perform RMSI combined detection according to the Q value, or the terminal device may assume that the terminal device is used in the DRS window The SSB candidate position for transmitting the SSB to be sent is determined according to the Q value, and the control resource set used to transmit the RMSI corresponding to the SSB to be sent is also determined according to the Q value.
