Downlink Control Information (Downlink Control Information, abbreviation DCI) is sent to terminal, the DCI It is carried on the PDCCH channel, the DCI is used to indicate the OSI carried on PDSCH channel described in the information window Information.

In Fig. 4, base station is identical by the OSI window of RMSI information configuration OSI1, OSI2, OSI3, to pass OSI-window 1.Base station notifies PDSCH channel scheduled in the terminal PDCCH by the DCI information that the PDCCH of OSI described in Fig. 4 is carried Which OSI upper carrying is.For example, using OSI described in 2bit instruction terminal in the DCI information that OSI PDCCH is carried Which OSI that carry on the corresponding OSI PDSCH channel of PDCCH is.For example, if the value of this two bit is 00, OSI PDSCH carrying is OSI1 message;If the value of this two bit is OSI2 message for 01, OSI PDSCH carrying; If the value of this two bit is OSI3 message for 10, OSI PDSCH carrying.

In Fig. 5, base station is identical by the OSI window of RMSI information configuration OSI1, OSI2, OSI3, is OSI-window1. What the DCI information that base station is carried by OSI PDCCH notified to carry on PDSCH channel scheduled in the terminal PDCCH is which A little OSI.For example, 3 ratios in the DCI information that base station by way of bitmap (bitmap), is carried using OSI PDCCH Spy, which OSI that carry on instruction terminal OSI PDSCH channel is.When bitmap value is 001, then OSI PDSCH is held What is carried is OSI1 information;When bitmap value is 110, then OSI PDSCH carrying is OSI2 and OSI3 information;

Terminal side, terminal go to receive according to the configuration of base station OSI-window in the corresponding OSI-window of target OSI Target OSI.For example, being as shown in figure 4, base station is identical by the OSI-window of RMSI information configuration OSI1, OSI2, OSI3 OSI-window1.Reception for target Other SI, terminal blind Detecting within the scope of the OSI-window where target OSI The PDCCH of OSI, the instruction information in DCI information that terminal is carried according to PDCCH, determines which OSI current PDCCH is PDCCH.More specifically, in the DCI information that OSI PDCCH is carried, the PDCCH institute of OSI described in 2bit instruction terminal is used Which OSI that carry on PDSCH channel scheduled in DCI information notice terminal PDCCH of carrying is.For example, this two bit Value is 00, then the carrying of PDSCH scheduled in OSI PDCCH is OSI1 information;Value 01, then OSI PDSCH carrying is OSI2 information;Value 02, then OSI PDSCH carrying is OSI3 information.

Terminal side, terminal go to receive according to the configuration of base station OSI-window in the corresponding OSI-window of target OSI Target OSI.For example, being as shown in figure 5, base station is identical by the OSI-window of RMSI information configuration OSI1, OSI2, OSI3 OSI-window1.Reception for target Other SI, terminal blind Detecting within the scope of the OSI-window where target OSI The PDCCH of OSI, the instruction information of OSI Fig. 5, determines which current PDCCH is in the DCI information that terminal is carried according to PDCCH Or the PDCCH of which OSI.More specifically, it in the DCI information that OSI PDCCH is carried, by way of bitmap, uses The current PDCCH of 3bit instruction terminal be which or which OSI PDCCH.For example, if the value of this three bit is 001, Terminal determines the PDCCH for the PDCCH of OSI1;If the value of this three bit is 011, then terminal determine the PDCCH for OSI1 and The PDCCH of OSI2;If the value of this three bit is 111, then terminal determines the PDCCH for OSI1, OSI2 and OSI's 3 PDCCH;

Further, on the basis of the above embodiments, before the OSI to terminal transmission, further includes:

According to the OSI that the PDSCH is carried, the cyclic redundancy check (Cyclic carried to PDCCH is determined Redundancy Check, abbreviation CRC) carry out scrambled wireless network temporarily identify (Radio Network Temporary, Abbreviation RNTI);

RNTI scrambling is carried out to the CRC of PDCCH carrying so that the terminal scramble according to the RNTI, determine and The corresponding OSI of the RNTI.

For example, in Fig. 4, base station is identical by the OSI-window of RMSI information configuration OSI1, OSI2, OSI3, For OSI-window1.For different Other SI information, on the cyclic redundancy check (CRC) that base station carries PDCCH channel It is scrambled using different RNTI, which OSI that notify to carry on PDSCH channel scheduled in the terminal PDCCH is.Example Such as, if the carrying of PDSCH scheduled in OSI PDCCH is OSI1 information, base station temporarily identifies RNTI sequence with wireless network The cyclic redundancy check (CRC) information that column 1 carry the PDCCH scrambles;If PDSCH scheduled in OSI PDCCH is held What is carried is OSI2 information, then base station scrambles the PDCCH CRC information carried with RNTI sequence 2;

In Fig. 5, base station is identical by the OSI-window of RMSI information configuration OSI1, OSI2, OSI3, is OSI- window1.For different Other SI information, carried out on the CRC that base station carries PDCCH channel using different RNTI Scrambling, which OSI that notify to carry on PDSCH channel scheduled in the terminal PDCCH is.For example, if OSI PDCCH is adjusted The PDSCH carrying of degree is OSI1 information, then base station scrambles the PDCCH CRC information carried with RNTI sequence 1; If the carrying of PDSCH scheduled in OSI PDCCH is OSI2 and OSI3 information, base station is with RNTI sequence 2 to the PDCCH institute The CRC information of carrying is scrambled;

Terminal side, terminal go to receive according to the configuration of base station OSI-window in the corresponding OSI-window of target OSI Target OSI.For example, being as shown in figure 4, base station is identical by the OSI-window of RMSI information configuration OSI1, OSI2, OSI3 OSI-window1.Reception for target Other SI, terminal blind Detecting within the scope of the OSI-window where target OSI The PDCCH of OSI, terminal is set with the CRC bit of RNTI information carried to PDCCH to be descrambled, and according to RNTI sequence and OSI it Between mapping relations, know that PDCCH is the PDCCH of which OSI.More specifically, in the range of OSI-window1, RNTI sequence Column 1 correspond to OSI1, the corresponding OSI2 of RNTI sequence 2, the corresponding OSI3 of RNTI sequence 3.Terminal is solved by attempting different RNTI It disturbs, and carries out CRC check.For example, if terminal is descrambled with RNTI 1, it can be by CRC check, then terminal determines current PDCCH is OSI1 PDCCH., can be by CRC check if terminal is descrambled with RNTI 2, then terminal determines current PDCCH is OSI2 PDCCH.

Terminal side, terminal go to receive according to the configuration of base station OSI-window in the corresponding OSI-window of target OSI Target OSI.For example, being as shown in figure 5, base station is identical by the OSI-window of RMSI information configuration OSI1, OSI2, OSI3 OSI-window1.Reception for target Other SI, terminal blind Detecting within the scope of the OSI-window where target OSI The PDCCH of OSI, terminal is set with the CRC bit of RNTI information carried to PDCCH to be descrambled, and according to RNTI sequence and OSI it Between mapping relations, know that PDCCH is which or which corresponding PDCCH of OSI.More specifically, OSIOSI-window1's In range, the corresponding OSI1 of RNTI sequence 1, the PDCCH of the corresponding OSI2 and OSI3 of RNTI sequence 2.Terminal is different by attempting RNTI is descrambled, and carries out CRC check.For example, if terminal is descrambled with RNTI 1, it can be by CRC check, then eventually End determines that current PDCCH is OSI1 PDCCH., can be by CRC check if terminal is descrambled with RNTI2, then terminal is sentenced Settled preceding PDCCH is the PDCCH of OSI2 and OSI3.

Specifically, base station is identical by the OSI-window of RMSI information configuration OSI1, OSI2, OSI3 in Fig. 4, it is OSI-window1.Base station is by carrying information notifies which OSI is terminal be on OSI PDSCH channel in Fig. 4.For example, OSI The information that PDSCH is carried includes OSI information and the Other SI instruction information of 2bit.When the Other SI of this two bit is indicated Information value is 00, then what the OSI PDSCH was carried is OSI1 information;When the Other SI of this two bit indicates information value It is 01, then what the OSI PDSCH was carried is OSI2 information;When this two bit Other SI instruction information value be 10, then What the OSI PDSCH was carried is OSI3 information;

In Fig. 5, base station is identical by the OSI-window of RMSI information configuration OSI1, OSI2, OSI3, is OSI- window1.Base station indicates OSI by the information carried on OSI PDSCH channel.For example, the packet that OSI PDSCH is carried Include OSI information and the Other SI instruction information of 3bit, the information that 3bit Other SI instruction information is carried in PDSCH In bit position be it is fixed.Base station is by way of bitmap, the letter of PDSCH scheduled in the base station instruction terminal PDCCH Which OSI that carry on road is.When bitmap value is 001, then OSI PDSCH carrying is OSI1 information;When Bitmap value is 110, then OSI PDSCH carrying is OSI2 and OSI3 information;

Terminal side, terminal go to receive according to the configuration of base station OSI-window in the corresponding OSI-window of target OSI Target OSI PDCCH.For example, as shown in figure 4, base station passes through the OSI-window phase of RMSI information configuration OSI1, OSI2, OSI3 It together, is OSI-window1.Reception for target Other SI, terminal are blind within the scope of the OSI-window where target OSI The PDCCH of OSI is detected, and goes to receive the information carried in corresponding PDSCH channel with the scheduling according to PDCCH.Terminal according to The instruction information of the OSI carried in PDSCH channel determines that current PDSCH is the PDSCH of which OSI.More specifically, OSI In the carried information of PDSCH, using carried on the current PDSCH channel of 2bit instruction terminal be which OSI information.For example, The value of this two bit is 00, then what the PDSCH was carried is the information of OSI1;If the value of this two bit is 01, then the PDSCH What is carried is the information of OSI2;If the value of this two bit is 10, then what the PDSCH was carried is the information of OSI3;

Terminal side, terminal go to receive according to the configuration of base station OSI-window in the corresponding OSI-window of target OSI Target OSI.For example, being as shown in figure 4, base station is identical by the OSI-window of RMSI information configuration OSI1, OSI2, OSI3 OSI-window1.Reception for target Other SI, terminal blind Detecting within the scope of the OSI-window where target OSI The PDCCH of OSI, and go to receive the information carried in corresponding PDSCH channel with the scheduling according to PDCCH.Terminal is believed according to PDSCH The instruction information of the OSI carried in road determines that current PDSCH is the PDSCH of which OSI.More specifically, OSI PDSCH institute In the DCI information of carrying, by way of bitmap, that using the current PDSCH of 3bit instruction terminal is which or which OSI PDSCH.For example, terminal determines the PDSCH for the PDSCH of OSI1 if the value of this three bit is 001;If this three bit Value be 110, then terminal determines the PDSCH for the PDSCH of OSI2 and OSI3;

It is further, on the basis of the above embodiments, described to send control information to the terminal, further includes:

Downlink Control Information DCI is sent to terminal, the DCI passes through PDCCH channel bearing, the DCI further include: be used for Indicate the PDCCH number that each OSI control information is carried in the information window.

Specifically, base station is identical by the OSI-window of RMSI information configuration OSI1, OSI2, OSI3 in Fig. 4, it is OSI-window1.Base station indicates current slot or mini-slot by the information carried on OSI PDCCH channel in Fig. 4 The number of upper OSI PDCCH.Only transmit OSI1's on slot or mini-slot in Fig. 4 where OSI1 PDCCH PDCCH, therefore base station is in the DCI information that OSI1 PDCCH is carried, on the instruction of display current slot or mini-slot only It only scheduled an OSI PDCCH.OSI2 is transmitted on slot or mini-slot in Fig. 4 where OSI2 PDCCH PDCCH and OSI3 PDCCH, therefore base station is in the DCI information that OSI2 PDCCH and OSI3 PDCCH are carried, the finger of display Show and scheduled two OSI PDCCH on current slot or mini-slot.

In Fig. 5, base station is identical by the OSI-window of RMSI information configuration OSI1, OSI2, OSI3, is OSI- window1.Base station indicates OSI on current slot or mini-slot by the information carried on middle OSI PDCCH channel The number of PDCCH.The PDCCH that OSI1 is only transmitted on slot or mini-slot in Fig. 5 where OSI1 PDCCH, because This base station only scheduled on the instruction of display current slot or mini-slot in the DCI information that OSI1 PDCCH is carried One OSI PDCCH.In Fig. 5, make to be carried on the same PDSCH channel for dispatching OSI2 and OSI3, the PDSCH channel It is dispatched with the same PDCCH.Only has the PDCCH of an OSI on slot or mini-slot where the PDCCH, therefore should The only PDCCH of an OSI on the current slot or mini-slot of instruction shown in the DCI information carried in PDCCH.

Terminal side, terminal carry out the blind Detecting of OSI PDCCH in OSI window, obtain the physics carried on OSI PDCCH Layer signaling information, and physical layer signaling information is read, to obtain the number for the OSI PDCCH being scheduled on current slot.Eventually End decides whether to continue blind Detecting OSI on current slot according to the information of number of the OSI PDCCH on the current slot of acquisition PDCCH。

For example, in Fig. 4, base station in the DCI information that OSI1 PDCCH is carried, the current slot of the instruction of display or It only scheduled an OSI PDCCH on mini-slot, then terminal determines only to scheduled on current slot or mini-slot One OSI PDCCH, then terminal judgement does not continue to the PDCCH of blind Detecting OSI on current slot.Base station is in OSI2 PDCCH In the DCI information carried, it scheduled two OSI PDCCH on the instruction of display current slot or mini-slot, then terminal is sentenced It scheduled two OSI PDCCH on settled preceding slot or mini-slot, then terminal will continue after detecting the PDCCH of OSI2 Detect OSI PDCCH.

Alternatively, terminal side, terminal carries out the blind Detecting of OSI PDCCH in OSI window, obtains and is carried on OSI PDCCH Physical layer signaling information, and physical layer signaling information is read, to obtain the number for the OSI being scheduled on current slot.Eventually The information of the number of OSI PDCCH, decides whether to continue blind Detecting on current slot on the current slot for holding according to or obtaining OSI PDCCH。

For example, in Fig. 5, base station in the DCI information that OSI1 PDCCH is carried, the current slot of the instruction of display or It only scheduled an OSI PDCCH on mini-slot, then terminal determines only to scheduled on current slot or mini-slot One OSI PDCCH, then terminal judgement do not continue to blind Detecting OSI PDCCH on current slot.Base station is in OSI2 PDCCH In the DCI information carried, an OSI PDCCH scheduled on the instruction of display current slot or mini-slot, then terminal is sentenced Settled preceding slot or mini-slot scheduled an OSI PDCCH, then terminal is detecting the corresponding PDCCH of OSI2 and OSI3 Afterwards, then terminal adjudicates the PDCCH that blind Detecting OSI is not continued on current slot.

Preferably, on the basis of the above embodiments, the DCI further include: be used to indicate the front and back of current PDCCH channel Frequency on whether have the PDCCH for carrying OSI control information.

Specifically, base station is current by the instruction terminal that the DCI information carried in PDCCH channel is shown in the embodiment On slot or mini-slot, whether there is OSI PDCCH in the frequency before current PDCCH channel;Meanwhile base station passes through On the current slot or mini slot of the instruction terminal that the DCI information carried in PDCCH channel is shown, after current PDCCH channel Whether OSI PDCCH is had in the frequency in face;

For example, base station is identical by the OSI-window of RMSI information configuration OSI1, OSI2, OSI3 in Fig. 4, it is OSI-window1.In the OSI-window, 0SI1, OSI2, one or more of OSI3 can be transmitted on a slot OSI.For example, the mode that OSI2 and OSI3 carries out frequency division multiplexing on the same slot is transmitted.Terminal is detecting OSI After PDCCH, in order to allow terminal to know whether the continuation blind Detecting others OSI PDCCH on current slot, base station passes through The transmission situation of OSI PDCCH on the current slot or mini-slot of instruction that the DCI information that PDCCH channel is carried is shown.More Specifically, base station passes through on the instruction terminal current slot or mini-slot that the DCI information carried in PDCCH channel is shown, when Whether there is OSI PDCCH in frequency before preceding PDCCH channel (or in lower frequency);Meanwhile base station is believed by PDCCH On the current slot or mini slot of the instruction terminal that the DCI information carried in road is shown, the subsequent frequency of current PDCCH channel Whether there is OSI PDCCH in rate (or in higher frequency).In Fig. 4, OSI2 and OSI3 are transmitted on the same slot, and (more low frequency) has OSI3 PDCCH before OSI2 PDCCH.Therefore, the 1bit that base station is carried in OSI2 PDCCH channel DCI information instruction terminal OSI2 PDCCH before (more low frequency) have the PDCCH of other OSI.Base station passes through OSI2 Without it in (higher frequency) behind the DCI information instruction terminal OSI2 PDCCH for the other 1bit that PDCCH channel is carried The PDCCH of its OSI.

Terminal side, terminal go to receive according to the configuration of base station OSI-window in the corresponding OSI-window of target OSI Target OSI.For example, being as shown in figure 4, base station is identical by the OSI-window of RMSI information configuration OSI1, OSI2, OSI3 OSI-window1.Reception for target Other SI, terminal blind Detecting within the scope of the OSI-window where target OSI Whether the PDCCH of OSI has OSI PDCCH in more low frequency and higher frequency in the DCI information that terminal is carried according to PDCCH, Terminal decides whether to continue blind Detecting OSI PDCCH in current time slots or mini-slot.For example, in Fig. 4, OSI2 and On slot (or mini-slot) where OSI3, terminal detects OSI PDCCH channel, and terminal successively detects from low to high OSI2 PDCCH and OSI3 PDCCH.When detecting OSI2 PDCCH channel, base station obtains the DCI information that the PDCCH is carried, And (more low frequency) does not have OSI PDCCH, DCI before DCI carries the current PDCCH channel of 1 bit indication in information (higher frequency) has OSI PDCCH after carrying the current PDCCH channel of another 1 bit indication in information.To which base station is sentenced It certainly needs to continue to continue blind Detecting OSI PDCCH in higher frequency.When detecting OSI2 PDCCH channel, base station is somebody's turn to do The DCI information that PDCCH is carried, and DCI carries (more low frequency before the current PDCCH channel of 1 bit indication in information Rate) there is no OSI PDCCH, DCI to carry after the current PDCCH channel of another 1 bit indication in information (higher frequency) There is no OSI PDCCH.To which base station judgement needs not continue to continue blind Detecting OSI PDCCH in higher frequency.

Further, in the above-described embodiments, the DCI further include: the subsequent time slot for being used to indicate current time slots is It is no to have the PDCCH for carrying the OSI control information.

Specifically, the instruction terminal that base station is shown by the DCI information carried in PDCCH channel is in current OSI-window In range, on the current subsequent slot or mini slot of slot or mini slot, if having the PDCCH of scheduling Other SI.

For example, base station is identical by the OSI-window of RMSI information configuration OSI1, OSI2, OSI3 in Fig. 4, it is OSI-window1.In the OSI-window, OSI1, OSI2, one or more of OSI3 can be transmitted on a slot OSI.For example, the mode that OSI2 and OSI3 carries out frequency division multiplexing on the same slot is transmitted.In order to allow terminal detecting To after OSI PDCCH, know that terminal within the scope of OSI-window1, current slot or the subsequent slot of mini-slot or Whether the PDCCH of blind Detecting OSI, finger that base station by DCI information that PDCCH channel carried shown are continued on mini-slot Show on current OSI-window1 the transmission situation of OSI PDCCH on slot or mini-slot below.More specifically, base station passes through In the current OSI-window1 of instruction terminal that the DCI information carried in PDCCH channel is shown, subsequent slot or mini-slot On whether have the PDCCH of Other SI.In Fig. 4, within the scope of OSI-window1, the subsequent slot of OSI1 PDCCH or There are the transmission of OSI2 PDCCH and OSI3 PDCCH on mini-slot.Therefore, base station is carried in OSI1 PDCCH channel The DCI information instruction terminal of 1bit, within the scope of current OSI-window1, on OSI1 PDCCH subsequent slot or mini-slot There is the PDCCH of other OSI.There is no OSI PDCCH on OSI2 PDCCH subsequent slot or mini-slot, therefore, base station exists The DCI information instruction terminal for the 1bit that OSI2 PDCCH channel is carried, within the scope of current OSI-window1, OSI2 PDCCH On subsequent slot or mini-slot, the not no PDCCH of OSI.Do not have on OSI3 PDCCH subsequent slot or mini-slot OSI PDCCH, therefore, the DCI information instruction terminal for the 1bit that base station is carried in OSI3 PDCCH channel, current OSI- Within the scope of window1, on OSI3 PDCCH subsequent slot or mini-slot, the not no PDCCH of OSI.

Terminal side, terminal go to receive according to the configuration of base station OSI-window in the corresponding OSI-window of target OSI Target OSI.For example, being as shown in figure 4, base station is identical by the OSI-window of RMSI information configuration OSI1, OSI2, OSI3 OSI-window1.Reception for target Other SI, terminal blind Detecting within the scope of the OSI-window where target OSI The PDCCH of OSI,

Terminal judges in current OSI-window according to the DCI information carried in PDCCH channel, subsequent slot or Whether the PDCCH of Other SI is had on mini-slot.

Terminal detects OSI PDCCH on the slot (or mini-slot) where OSI1 PDCCH, and passes through OSI 1 bit information in DCI information that PDCCH channel is carried, terminal judge within the scope of current OSI-window, current slot Whether the subsequent slot (or mini-slot) of (or mini-slot) needs to detect OSI PDCCH.For example, working as OSI PDCCH When 1 bit information in DCI information that channel is carried is 0, then terminal is adjudicated within the scope of current OSI-window, current slot The subsequent slot (or mini-slot) of (or mini-slot) no longer detects OSI PDCCH without OSI PDCCH.

Terminal detects OSI PDCCH on the slot (or mini-slot) where OSI1 PDCCH, and passes through OSI 1 bit information in DCI information that PDCCH channel is carried, terminal judge within the scope of current OSI-window, current slot Whether the subsequent slot (or mini-slot) of (or mini-slot) needs to detect OSI PDCCH.For example, working as OSI PDCCH 1 bit information in DCI information that channel is carried is 1, then terminal is adjudicated within the scope of current OSI-window, current slot The subsequent slot (or mini-slot) of (or mini-slot) has an OSI PDCCH, thus terminal continue below slot (or Mini-slot OSI PDCCH is detected on).On the slot (or mini-slot) where OSI2 PDCCH, OSI2 PDCCH letter 1 bit information in DCI information that road is carried is 0, then terminal is adjudicated within the scope of current OSI-window, current slot (or Mini-slot subsequent slot (or mini-slot)) does not have an OSI PDCCH, thus terminal is in slot (or mini- below Slot OSI PDCCH is no longer detected on).

Preferably, on the basis of the above embodiments, at least one described information window setting is carried out using one group of wave beam The standard of transmission is total in position (Quasi-Co-Location, abbreviation QCL) window, and the different QCL windows include the identical information Window.

Fig. 6 is schematic diagram of the OSI configuration in QCL window of one embodiment of transmission method of present system information;Such as Fig. 6 institute Show, the multiple quasi- position QCL windows altogether of base station configuration, include multiple OSI-window in a QCL window.For different QCL windows, The configuring condition of OSI window in QCL-window is identical, i.e., the number for the OSI-window for including in different Q CL window is identical, right In n-th OSI-window in any x-th of QCL window and y-th of QCL window, x-th of QCL window, with y-th of QCL window The identical OSI that N number of OSI-window includes.For different QCL windows, the characteristic of channel is different.For example, different Q CL window uses Wave beam it is different, as shown in fig. 6, first QCL window uses first group of wave beam, such as first group of wave beam includes wave beam 1 and wave beam 2;Second QCL window uses second group of wave beam, such as second group of wave beam includes wave beam 3 and wave beam 4;

Fig. 6 is a specific example of the present embodiment, and in Fig. 6, base station configures 2 QCL windows, in the two QCL windows OSI-window configuring condition it is identical.More specifically, in each QCL window, base station configures 2 Other SI windows.For The OSI that the same OSI-window in two QCL windows includes is identical.Either in QCL window 1, or in QCL window 2, together One OSI-window includes identical OSI.It should be noted that the OSI that the corresponding same OSI window of different Q CL window includes is identical, Refer to that the OSI being likely to occur in same OSI window is identical, the OSI of actual transmissions can be different.Similarly, the OSI that OSI window includes is Refer to the OSI being likely to occur in the OSI window, in actual transmissions, allow partially or completely OSI therein in the OSI window not by Transmission.

Given OSI message is received for terminal, terminal goes to receive the OSI in the QCL window where object beam direction. Also, terminal goes to receive the OSI in the corresponding OSI window of the OSI.For example, as shown in fig. 6, QCL window 1 includes wave beam 1 With wave beam 2, QCL window 2 includes wave beam 3 and wave beam 4.OSI-window1 includes OSI1 and OSI2, and OSI-window2 includes OSI 3 And OSI4.

So, if the known signal strength on wave beam 2 of terminal is stronger, if terminal needs to receive OSI2, that Terminal removes the PDCCH of detection OSI2 in the corresponding QCL window 1 of wave beam 2.Also, OSI2 corresponds to OSI- known to terminal Window1, then terminal removes the PDCCH of detection OSI2 within the scope of OSI window1.According to the two features, which is determined OSI window 1 in QCL window1 gets on to detect the PDCCH of OSI2.
