Background technique

In a new generation of wireless communication systems, carrier frequencies higher than the carrier frequency used by fourth generation (4G) communication systems, such as carrier frequencies of 28 GHz, 45 GHz, 70 GHz, and even higher, will be used. In order to ensure the coverage performance of high frequency communication, beamforming can be used to improve the antenna gain.

Generally, in the process of the terminal initially accessing the network, the terminal needs to perform measurement and identification of the preliminary beam direction of the base station, thereby determining an optional uplink and downlink transmission and reception beam, that is, when the terminal initially accesses the network covered by the base station, the base station The downlink system information may be sent to the terminal, where the downlink system information includes a master information block (MIB) and a system information block (SIB), where the SIB may include: remaining minimum system information RMSI and others Other System Information (other SI message), and other SI functions similarly to SI messages in LTE.

If the other SI message window adopts the same mechanism as the LTE in the next-generation wireless communication system, that is, each OSI window is configured with an OSI window (SI-window), the OSI windows corresponding to different Other SI messages do not overlap. In other words, the transmission between different Other SI messages is time-division.

According to an exemplary embodiment, the PDSCHs carrying different OSIs are on the same time slot, that is, the PDSCHs carrying different OSIs may be frequency division multiplexed in the same time slot, for example, OSI2 PDSCH and OSI3 PDSCH. . It should be noted that only one OSI is carried on one PDSCH channel.

At least two of the OSIs are encoded and carried on the same PDSCH channel.

5 is a schematic diagram of an OSI configured in an information window according to an embodiment of a method for transmitting system information according to the present disclosure; as shown in FIG. 5, a base station puts information bits of OSI2 and OSI3 together for channel coding, rate matching, resource mapping, and the like. Operation, forming a PDSCH channel for carrying both OSI2 and OSI3.

According to an exemplary embodiment, on the basis of the foregoing embodiment, the sending, to the terminal, control information, so that the terminal obtains, by using control information, a scheduling of a physical downlink shared channel (PDSCH) channel for carrying the OSI. Information, including:

The downlink control information (Downlink Control Information, DCI for short) is transmitted to the terminal, where the DCI is carried on the PDCCH channel, and the DCI is used to indicate information about the OSI carried on the PDSCH channel in the information window.

In FIG. 4, the base station configures OSI1, OSI2, and OSI3 with the same OSI window through the RMSI information, and transmits OSI-window 1. The base station informs the terminal of which OSI is carried on the PDSCH channel scheduled by the PDCCH by using the DCI information carried by the PDCCH of the OSI described in FIG. 4 . For example, in the DCI information carried by the OSI PDCCH, 2 OS is used to indicate which OSI is carried on the OSI PDSCH channel corresponding to the OSI PDCCH described by the terminal. For example, if the value of the two bits is 00, the OSI PDSCH carries the OSI1 message; if the value of the two bits is 01, the OSI PDSCH carries the OSI2 message; if the values of the two bits are 10, the OSI PDSCH carries the OSI3 message.

In FIG. 5, the base station configures OSI1, OSI2, and OSI3 with the same OSI window as RMSI information, which is OSI-window1. The base station informs the terminal of which OSIs are carried on the PDSCH channel scheduled by the PDCCH by using the DCI information carried by the OSI PDCCH. For example, the base station uses the 3 bits in the DCI information carried by the OSI PDCCH in a bitmap (bitmap) manner to indicate which OSIs are carried on the OSI PDSCH channel of the terminal. When the value of the bitmap is 001, the OSI PDSCH carries the OSI1 information; when the bitmap value is 110, the OSI PDSCH carries the OSI2 and OSI3 information;

On the terminal side, the terminal receives the target OSI in the OSI-window corresponding to the target OSI according to the configuration of the base station OSI-window. For example, as shown in FIG. 4, the base station configures the OSI-window of OSI1, OSI2, and OSI3 to be OSI-window1 through the RMSI information. For receiving the target other SI, the terminal blindly detects the PDCCH of the OSI in the OSI-window range in which the target OSI is located, and the terminal determines which OSI PDCCH the current PDCCH is based on the indication information in the DCI information carried by the PDCCH. More specifically, in the DCI information carried by the OSI PDCCH, the DCI information carried by the PDCCH of the OSI indicating the terminal is used to notify the terminal which OSI is carried on the PDSCH channel scheduled by the PDCCH. For example, if the value of the two bits is 00, the PDSCH scheduled by the OSI PDCCH carries the OSI1 information. If the value is 01, the OSI PDSCH carries the OSI2 information. If the value 02, the OSI PDSCH carries the OSI3 information.

On the terminal side, the terminal receives the target OSI in the OSI-window corresponding to the target OSI according to the configuration of the base station OSI-window. For example, as shown in FIG. 5, the base station configures the OSI-window of OSI1, OSI2, and OSI3 to be OSI-window1 through the RMSI information. For the reception of the target other SI, the terminal blindly detects the PDCCH of the OSI in the OSI-window range in which the target OSI is located, and the terminal determines, according to the indication information of the OSI FIG. 5 in the DCI information carried by the PDCCH, which PDCCH is the current PDCCH or which OSI PDCCH. . More specifically, in the DCI information carried by the OSI PDCCH, 3 bits are used to indicate which PDCCH of the OSI or PDCCH of the current PDCCH is used by the terminal. For example, if the value of the three bits is 001, the terminal determines that the PDCCH is the PDCCH of OSI1; if the value of the three bits is 011, the terminal determines that the PDCCH is the PDCCH of OSI1 and OSI2; if the three bits are taken The value is 111, the terminal determines that the PDCCH is a PDCCH of OSI1, OSI2, and OSI3;

Determining a Radio Network Temporary (RNTI) for scrambling a Cyclic Redundancy Check (CRC) carried by the PDCCH according to the OSI carried by the PDSCH;

For example, in FIG. 4, the base station configures the OSI-window of OSI1, OSI2, and OSI3 to be the same as OSI-window1 through the RMSI information. For different Other SI information, the base station scrambles different cyclic RNs on the cyclic redundancy check CRC carried by the PDCCH channel, and notifies the terminal which OSI is carried on the PDSCH channel scheduled by the PDCCH. For example, if the PDSCH scheduled by the OSI PDCCH carries the OSI1 information, the base station temporarily identifies the cyclic redundancy check CRC information carried by the PDCCH by using the radio network temporary identification RNTI sequence 1; if the PDSCH bearer scheduled by the OSI PDCCH The OSI2 information is used by the base station to scramble the CRC information carried by the PDCCH by using the RNTI sequence 2;

In FIG. 5, the base station configures the OSI-window of OSI1, OSI2, and OSI3 to be OSI-window1 through the RMSI information. For different Other SI information, the base station scrambles different RNTIs on the CRC carried by the PDCCH channel, and notifies the terminal which OSIs are carried on the PDSCH channel scheduled by the PDCCH. For example, if the PDSCH scheduled by the OSI PDCCH carries the OSI1 information, the base station scrambles the CRC information carried by the PDCCH by using the RNTI sequence 1; if the PDSCH scheduled by the OSI PDCCH carries the OSI2 and OSI3 information, the base station The CRC information carried by the PDCCH is scrambled by using the RNTI sequence 2;

On the terminal side, the terminal receives the target OSI in the OSI-window corresponding to the target OSI according to the configuration of the base station OSI-window. For example, as shown in FIG. 4, the base station configures the OSI-window of OSI1, OSI2, and OSI3 to be OSI-window1 through the RMSI information. For receiving the target Other SI, the terminal blindly detects the PDCCH of the OSI in the OSI-window range where the target OSI is located, and the terminal uses the RNTI to descramble the CRC position of the information carried by the PDCCH, and according to the mapping relationship between the RNTI sequence and the OSI. It is known which PDCCH is the PDCCH of the PDCCH. More specifically, within the scope of OSI-window1, RNTI sequence 1 corresponds to OSI1, RNTI sequence 2 corresponds to OSI2, and RNTI sequence 3 corresponds to OSI3. The terminal descrambles by trying different RNTIs and performs CRC check. For example, if the terminal performs descrambling with RNTI 1, the CRC can be verified, and the terminal determines that the current PDCCH is the OSI1 PDCCH. If the terminal performs descrambling with RNTI 2, and the CRC check is performed, the terminal determines that the current PDCCH is the OSI2 PDCCH.

On the terminal side, the terminal receives the target OSI in the OSI-window corresponding to the target OSI according to the configuration of the base station OSI-window. For example, as shown in FIG. 5, the base station configures the OSI-window of OSI1, OSI2, and OSI3 to be OSI-window1 through the RMSI information. For receiving the target Other SI, the terminal blindly detects the PDCCH of the OSI in the OSI-window range where the target OSI is located, and the terminal uses the RNTI to descramble the CRC position of the information carried by the PDCCH, and according to the mapping relationship between the RNTI sequence and the OSI. Obtain which PDCCH is the PDCCH to which the PDCCH corresponds. More specifically, within the scope of OSIOSI-window1, RNTI sequence 1 corresponds to OSI1, and RNTI sequence 2 corresponds to PDCCHs of OSI2 and OSI3. The terminal descrambles by trying different RNTIs and performs CRC check. For example, if the terminal performs descrambling with RNTI 1, the CRC can be verified, and the terminal determines that the current PDCCH is the OSI1 PDCCH. If the terminal performs descrambling with RNTI 2, the CRC can be verified, and the terminal determines that the current PDCCH is the PDCCH of OSI2 and OSI3.

On the basis of the foregoing embodiment, the sending the OSI to the terminal further includes:

The OSI indication information in the embodiment is carried on a physical downlink shared channel (PDSCH) channel, and the OSI indication information is used to indicate information about an OSI carried on the PDSCH channel in the information window.

In FIG. 4, the base station configures the OSI-window of OSI1, OSI2, and OSI3 to be OSI-window1 through the RMSI information. The base station informs the terminal which OSI is by carrying information on the OSI PDSCH channel in FIG. For example, the information carried by the OSI PDSCH includes OSI information and 2 bits of Other SI indication information. When the other SI indication information of the two bits is 00, the OSI PDSCH carries the OSI1 information; when the Other SI indication information of the two bits takes the value of 01, the OSI PDSCH carries the OSI2 information; When the value of the two bit Other SI indication information is 10, the OSI PDSCH carries the OSI3 information;

In FIG. 5, the base station configures the OSI-window of OSI1, OSI2, and OSI3 to be OSI-window1 through the RMSI information. The base station indicates the OSI through information carried on the OSI PDSCH channel. For example, the information carried by the OSI PDSCH includes OSI information and 3-bit Other SI indication information, and the bit position of the information in the information carried by the PDSCH is fixed. The base station indicates, by means of a bitmap, which OSIs are carried on the PDSCH channel scheduled by the PDCCH by the terminal. When the value of the bitmap is 001, the OSI PDSCH carries the OSI1 information; when the bitmap value is 110, the OSI PDSCH carries the OSI2 and OSI3 information;

On the terminal side, the terminal receives the target OSI PDCCH in the OSI-window corresponding to the target OSI according to the configuration of the base station OSI-window. For example, as shown in FIG. 4, the base station configures the OSI-window of OSI1, OSI2, and OSI3 to be OSI-window1 through the RMSI information. For the reception of the target Other SI, the terminal blindly detects the PDCCH of the OSI in the OSI-window range where the target OSI is located, and receives the information carried in the corresponding PDSCH channel according to the scheduling of the PDCCH. The terminal determines which OSI PDSCH the current PDSCH is based on the indication information of the OSI carried in the PDSCH channel. More specifically, in the information carried by the OSI PDSCH, 2 bits are used to indicate which OSI information is carried on the current PDSCH channel of the terminal. For example, if the value of the two bits is 00, the PDSCH carries the information of the OSI1. If the value of the two bits is 01, the PDSCH carries the information of the OSI2; if the value of the two bits is 10, , the PDSCH carries the information of the OSI3;

On the terminal side, the terminal receives the target OSI in the OSI-window corresponding to the target OSI according to the configuration of the base station OSI-window. For example, as shown in FIG. 4, the base station configures the OSI-window of OSI1, OSI2, and OSI3 to be OSI-window1 through the RMSI information. For the reception of the target Other SI, the terminal blindly detects the PDCCH of the OSI in the OSI-window range where the target OSI is located, and receives the information carried in the corresponding PDSCH channel according to the scheduling of the PDCCH. The terminal determines which OSI PDSCH the current PDSCH is based on the indication information of the OSI carried in the PDSCH channel. More specifically, in the DCI information carried by the OSI PDSCH, 3 bits are used to indicate which or which OSI PDSCH of the current PDSCH is the terminal by means of a bitmap. For example, if the value of the three bits is 001, the terminal determines that the PDSCH is the PDSCH of the OSI1; if the value of the three bits is 110, the terminal determines that the PDSCH is the PDSCH of the OSI2 and the OSI3;

On the basis of the foregoing embodiment, the sending the control information to the terminal further includes:

In FIG. 4, the base station configures the OSI-window of OSI1, OSI2, and OSI3 to be OSI-window1 through the RMSI information. The base station indicates the number of OSI PDCCHs on the current slot or mini-slot through the information carried on the OSI PDCCH channel in FIG. In the slot or mini-slot where the OSI1 PDCCH is located in FIG. 4, only the PDCCH of the OSI1 is transmitted. Therefore, in the DCI information carried by the OSI1 PDCCH, the base station indicates that only one OSI PDCCH is scheduled on the current slot or mini-slot. The OSI2 PDCCH and the OSI3 PDCCH are transmitted on the slot or the mini-slot where the OSI2 PDCCH is located in FIG. 4, so the base station displays two indications on the current slot or mini-slot in the DCI information carried by the OSI2 PDCCH and the OSI3 PDCCH. OSI PDCCH.

In FIG. 5, the base station configures the OSI-window of OSI1, OSI2, and OSI3 to be OSI-window1 through the RMSI information. The base station indicates the number of OSI PDCCHs on the current slot or mini-slot through the information carried on the medium OSI PDCCH channel. In the slot or mini-slot where the OSI1 PDCCH is located in FIG. 5, only the PDCCH of the OSI1 is transmitted. Therefore, the base station displays in the DCI information carried by the OSI1 PDCCH that only one OSI PDCCH is scheduled on the current slot or mini-slot. In FIG. 5, for scheduling OSI2 and OSI3 to be carried on the same PDSCH channel, the PDSCH channel is scheduled with the same PDCCH. There is only one PDCCH of the OSI on the slot or mini-slot where the PDCCH is located. Therefore, the PDCCH indicating that there is only one OSI on the current slot or mini-slot displayed in the DCI information carried in the PDCCH.

On the terminal side, the terminal performs blind detection of the OSI PDCCH in the OSI window, obtains physical layer signaling information carried on the OSI PDCCH, and reads physical layer signaling information, thereby obtaining the number of scheduled OSI PDCCHs on the current slot. The terminal determines whether to continue to blindly detect the OSI PDCCH on the current slot according to the obtained number of OSI PDCCHs on the current slot.

For example, in FIG. 4, the base station indicates that only one OSI PDCCH is scheduled on the current slot or mini-slot in the DCI information carried by the OSI1 PDCCH, and the terminal determines that only one OSI is scheduled on the current slot or mini-slot. PDCCH, the terminal decides that the PDCCH of the OSI is no longer blindly detected on the current slot. The base station in the DCI information carried by the OSI2 PDCCH indicates that two OSI PDCCHs are scheduled on the current slot or mini-slot, and the terminal determines that two OSI PDCCHs are scheduled on the current slot or mini-slot, and the terminal detects that After the PDCCH of OSI2, the OSI PDCCH will continue to be detected.

Or, on the terminal side, the terminal performs blind detection of the OSI PDCCH in the OSI window, obtains physical layer signaling information carried on the OSI PDCCH, and reads physical layer signaling information, thereby obtaining the number of scheduled OSIs on the current slot. . The terminal determines whether to continue to blindly detect the OSI PDCCH on the current slot according to the information of the number of OSI PDCCHs on the current slot obtained or obtained.

For example, in FIG. 5, the base station indicates that only one OSI PDCCH is scheduled on the current slot or mini-slot in the DCI information carried by the OSI1 PDCCH, and the terminal determines that only one OSI is scheduled on the current slot or mini-slot. The PDCCH, the terminal decides that the OSI PDCCH is no longer blindly detected on the current slot. The base station indicates, in the DCI information carried by the OSI2 PDCCH, that an OSI PDCCH is scheduled on the current slot or mini-slot, and the terminal determines that the current slot or mini-slot schedules an OSI PDCCH, and the terminal detects the OSI2 and the OSI3. After the corresponding PDCCH, the terminal decides that the PDCCH of the OSI is no longer blindly detected on the current slot.

Optionally, on the basis of the foregoing embodiment, the DCI further includes: a PDCCH for indicating whether the OSI control information is carried on a frequency before and after the current PDCCH channel.

In this embodiment, the base station indicates, by using the DCI information carried in the PDCCH channel, whether there is an OSI PDCCH on the current slot of the current PDCCH channel on the current slot or mini-slot of the terminal; and the DCI information carried by the base station through the PDCCH channel. The displayed terminal indicates whether there is an OSI PDCCH on the current slot or the mini slot, and the frequency behind the current PDCCH channel;

For example, in FIG. 4, the base station configures the OSI-window of OSI1, OSI2, and OSI3 by the RMSI information to be the same as OSI-window1. In the OSI-window, one or more OSIs of 0SI1, OSI2, and OSI3 can be transmitted on one slot. For example, OSI2 and OSI3 are transmitted in a frequency division multiplexed manner on the same slot. After the terminal detects the OSI PDCCH, in order to let the terminal know whether to continue to blindly detect other OSI PDCCHs on the current slot, the base station indicates the transmission status of the OSI PDCCH on the current slot or mini-slot through the DCI information carried by the PDCCH channel. More specifically, the base station indicates, by using the DCI information carried in the PDCCH channel, whether the OSI PDCCH is present on the current slot or mini-slot of the current PDCCH channel, and the base station passes the frequency of the previous PDCCH channel (or lower frequency); The DCI information carried in the PDCCH channel indicates whether there is an OSI PDCCH on the current slot or mini slot of the terminal, on the frequency (or higher frequency) of the current PDCCH channel. In FIG. 4, OSI2 and OSI3 are transmitted on the same slot, and the front (lower frequency) of the OSI2 PDCCH has an OSI3 PDCCH. Therefore, the 1-bit DCI information carried by the base station on the OSI2 PDCCH channel indicates that the PDCCH of the other OSI is in front of the terminal OSI2 PDCCH (lower frequency). The other 1 bit of DCI information carried by the base station through the OSI2 PDCCH channel indicates that there is no PDCCH of other OSIs behind the UE OSI2 PDCCH (higher frequency).

On the terminal side, the terminal receives the target OSI in the OSI-window corresponding to the target OSI according to the configuration of the base station OSI-window. For example, as shown in FIG. 4, the base station configures the OSI-window of OSI1, OSI2, and OSI3 to be OSI-window1 through the RMSI information. For the reception of the target Other SI, the terminal blindly detects the PDCCH of the OSI in the OSI-window range in which the target OSI is located, and the terminal determines whether the terminal has the OSI PDCCH according to the lower frequency and higher frequency in the DCI information carried by the PDCCH. The OSI PDCCH is continuously detected blindly on the current time slot or mini-slot. For example, in FIG. 4, on the slot (or mini-slot) where OSI2 and OSI3 are located, the terminal detects the OSI PDCCH channel, and the terminal sequentially detects the OSI2 PDCCH and the OSI3 PDCCH from low frequency to high frequency. When detecting the OSI2 PDCCH channel, the base station obtains DCI information carried by the PDCCH, and 1 bit in the DCI bearer information indicates that there is no OSI PDCCH before the current PDCCH channel (lower frequency), and another bit in the DCI bearer information Indicates that there is an OSI PDCCH after the current PDCCH channel (higher frequency). Thus, the base station decides that it is necessary to continue to blindly detect the OSI PDCCH at a higher frequency. When detecting the OSI2 PDCCH channel, the base station obtains DCI information carried by the PDCCH, and 1 bit in the DCI bearer information indicates that there is no OSI PDCCH before the current PDCCH channel (lower frequency), and another bit in the DCI bearer information It indicates that there is no OSI PDCCH after the current PDCCH channel (higher frequency). Thus, the base station decides that it is not necessary to continue to blindly detect the OSI PDCCH on higher frequencies.

In the above embodiment, the DCI further includes: a PDCCH for indicating whether a subsequent time slot of the current time slot carries the OSI control information.

The PDCCH indicating that the other SI is scheduled by the base station in the current OSI-window range, the current slot or the slot behind the mini slot or the mini slot is displayed by the base station through the DCI information carried in the PDCCH channel.

For example, in FIG. 4, the base station configures the OSI-window of OSI1, OSI2, and OSI3 by the RMSI information to be the same as OSI-window1. In the OSI-window, one or more OSIs in OSI1, OSI2, and OSI3 can be transmitted on one slot. For example, OSI2 and OSI3 are transmitted in a frequency division multiplexed manner on the same slot. After the terminal detects that the OSI PDCCH is detected, the terminal is made aware of whether the PDCCH of the OSI is continuously detected on the slot or the mini-slot behind the current slot or the mini-slot in the range of the OSI-window1, and the DCI carried by the base station through the PDCCH channel. The information display indicates the transmission of the OSI PDCCH on the subsequent slot or mini-slot on the current OSI-window1. More specifically, the base station indicates whether there is a PDCCH of Other SI in the current OSI-window1, the subsequent slot or the mini-slot through the DCI information carried in the PDCCH channel. In FIG. 4, in the OSI-window1 range, there is a transmission of OSI2 PDCCH and OSI3 PDCCH on the slot or mini-slot behind the OSI1 PDCCH. Therefore, the 1-bit DCI information carried by the base station on the OSI1 PDCCH channel indicates that the terminal has a PDCCH of another OSI on the slot or mini-slot behind the OSI1 PDCCH in the current OSI-window1 range. There is no OSI PDCCH on the slot or mini-slot behind the OSI2 PDCCH. Therefore, the 1-bit DCI information carried by the base station on the OSI2 PDCCH channel indicates the terminal, the current OSI-window1 range, and the slot or mini-slot behind the OSI2 PDCCH. PDCCH of OSI. There is no OSI PDCCH on the slot or mini-slot behind the OSI3 PDCCH. Therefore, the 1-bit DCI information carried by the base station on the OSI3 PDCCH channel indicates that the terminal, the current OSI-window1 range, the slot or mini-slot behind the OSI3 PDCCH, PDCCH of OSI.

On the terminal side, the terminal receives the target OSI in the OSI-window corresponding to the target OSI according to the configuration of the base station OSI-window. For example, as shown in FIG. 4, the base station configures the OSI-window of OSI1, OSI2, and OSI3 to be OSI-window1 through the RMSI information. For the reception of the target Other SI, the terminal blindly detects the PDCCH of the OSI in the OSI-window range where the target OSI is located.

The terminal determines whether there is a PDCCH of Other SI in the current OSI-window and the subsequent slot or mini-slot according to the DCI information carried in the PDCCH channel.

The terminal detects the OSI PDCCH on the slot (or mini-slot) where the OSI1 PDCCH is located, and uses the 1-bit information in the DCI information carried by the OSI PDCCH channel, and the terminal determines the current slot (or mini-slot in the current OSI-window range). Whether the subsequent slot (or mini-slot) needs to detect the OSI PDCCH. For example, when the 1-bit information in the DCI information carried by the OSI PDCCH channel is 0, the terminal determines that the slot (or mini-slot) behind the current slot (or mini-slot) has no OSI in the current OSI-window range. PDCCH, thus no longer detecting the OSI PDCCH.

The terminal detects the OSI PDCCH on the slot (or mini-slot) where the OSI1 PDCCH is located, and uses the 1-bit information in the DCI information carried by the OSI PDCCH channel, and the terminal determines the current slot (or mini-slot in the current OSI-window range). Whether the subsequent slot (or mini-slot) needs to detect the OSI PDCCH. For example, when the 1-bit information in the DCI information carried by the OSI PDCCH channel is 1, the terminal determines that the current slot (or mini-slot) of the current slot (or mini-slot) has the OSI PDCCH in the current OSI-window range. Therefore, the terminal continues to detect the OSI PDCCH on the subsequent slot (or mini-slot). On the slot (or mini-slot) where the OSI2 PDCCH is located, the 1-bit information in the DCI information carried by the OSI2 PDCCH channel is 0, and the terminal determines the current OSI-window range, behind the current slot (or mini-slot). The slot (or mini-slot) has no OSI PDCCH, so the terminal no longer detects the OSI PDCCH on subsequent slots (or mini-slots).

For different QCL windows, the configuration of the OSI window in QCL-window is the same, that is, the number of OSI-windows contained in different QCL windows is the same, for any xth QCL window and yth QCL window, xth QCL The Nth OSI-window in the window is the same OSI as the Nth OSI-window in the yth QCL window. The channel characteristics are different for different QCL windows. For example, different QCL windows use different beams. As shown in FIG. 6, the first QCL window uses a first set of beams, for example, the first set of beams includes beam 1 and beam 2; the second QCL window uses a second set of beams, For example, the second group of beams includes beam 3 and beam 4;

Whether in the QCL window 1 or in the QCL window 2, the same OSI-window contains the same OSI. It should be noted that the same OSI window corresponding to different QCL windows includes the same OSI, which means that the OSI may appear in the same OSI window, and the actual transmitted OSI may be different. Similarly, the OSI contained in the OSI window refers to the OSI that may appear in the OSI window. In actual transmission, some or even all of the OSIs are allowed to be not transmitted in the OSI window.

For the terminal to receive a given OSI message, the terminal receives the OSI in the QCL window in which the target beam direction is located. And, the terminal receives the OSI in the OSI window corresponding to the OSI. For example, as shown in FIG. 6, QCL window 1 includes beam 1 and beam 2, and QCL window 2 includes beam 3 and beam 4. OSI-window1 contains OSI1 and OSI2, and OSI-window2 contains OSI 3 and OSI4.

Then, if the terminal knows that the signal strength on the beam 2 is strong, then the terminal needs to receive the OSI2, then the terminal detects the PDCCH of the OSI2 in the QCL window 1 corresponding to the beam 2. Moreover, if the terminal knows that OSI2 corresponds to OSI-window1, the terminal detects the PDCCH of OSI2 within the range of OSI window1. According to these two characteristics, the UE determines to detect the PDCCH of OSI2 on the OSI window 1 in the QCL window 1.
