Under this combination, switch indication field may include three bits, use three bit indications first Switch state and second switch state.For example, the use of the first switch state that bit 000,001 or 010 indicates being certain close State and the second switch state of instruction are certain closed state；The first switch state indicated using bit 011 is certain Open state and the second switch state of instruction are certain open state；The first switch state indicated using bit 100 is Certain open state and the second switch state of instruction are can be with open state；The first switch shape indicated using bit 101 State is that the second switch state of certain open state and instruction is certain closed state；It is opened using first that bit 110 indicates Off status is that the second switch state of certain closed state and instruction is certain open state；Indicated using bit 111 One switch state be can be certain open state with the second switch state of open state and instruction.
For example, with reference to Fig. 2-6, first switch indication field, second switch indication field, third switch indication field and the Four switch indication fields occupy three bits.For first switch indication field, existed using the instruction of bit 000,001 or 010 First switch state in BTI is certain closed state and indicates that the second switch state in BTI is certain closed state； It the use of first switch state of the instruction of bit 011 in BTI is the second switch shape of certain open state and instruction in BTI State is certain open state；It the use of first switch state of the instruction of bit 100 in BTI is that certain open state and instruction exist Second switch state in BTI is can be with open state；It the use of first switch state of the instruction of bit 101 in BTI is certain The second switch state of open state and instruction in BTI is certain closed state；Using the instruction of bit 110 in BTI First switch state is certain closed state and indicates that the second switch state in BTI is certain open state；Using than First switch state of the instruction of feature 111 in BTI is that can be with the second switch state of open state and instruction in BTI Certain open state.The meaning of field is identical to be referred to for second switch indication field, third switch indication field and the 4th switch, It is no longer described in detail herein.
Optionally, when also needing the 4th switch to refer to first of field instruction first transceiver in each period of the day from 11 p.m. to 1 a.m phase in DTI When second switch state in each period of the day from 11 p.m. to 1 a.m phase in DTI of switch state and instruction second transceiver, the 4th switch instruction word Section may include six bits, and the first subfield and the second subfield in the 4th switch indication field can occupy three ratios Spy, for the first subfield and the second subfield meaning with referring to the description to first switch indication field, herein also no longer It is described in detail.
Wherein, it should be understood that the first equipment is before receiving or sending data using second transceiver, needs to Two transceivers carry out wave beam training.Wherein, the first equipment carries out wave beam training to second transceiver in the BTI of BI and A-BFT, Then the DTI each period of the day from 11 p.m. to 1 a.m phase for including is distributed in ATI, the first equipment can be with transmission services in DTI.So in BTI, A-BFT In ATI, switch instruction information needs to indicate that the second switch state of second transceiver is open state.And in DTI, open The second switch state of pass indication field instruction second transceiver can be in off state or open state.
Optionally, the bandwidth of the second frequency range as where second transceiver is larger, so the 4th switch indication field refers to The second switch state typically open state shown or not necessarily open state can guarantee that in DTI, first sets in this way It is standby to open second transceiver to be properly received or send data.
First equipment can be used first transceiver auxiliary and carry out wave beam training to second transceiver, can also be without using the One transceiver assists the wave beam training to second transceiver.So switch instruction information can respectively in BTI, A-BFT and ATI To indicate the first switch state of first transceiver as open state or closed state.And in DTI, switch indication field refers to Showing the state of first transceiver can be in off state or open state.
Optionally, switch instruction information first switch state of the instruction in BTI and the first switch state in A-BFT It can be open state, the first equipment opens the first transmitting-receiving according to first switch state in this way in BTI and in A-BFT Device can be used first transceiver auxiliary and carry out wave beam training to second transceiver.And switch instruction information instruction is in ATI First switch state and the first switch state in DTI can be in off state, in this way in ATI and in DTI One equipment closes first transceiver according to first switch state, can reduce the power consumption of the first equipment.
It wherein, referring to fig. 2-7, include AW for suspend mode BI, each CBAP of the DTI of the BI, the second equipment needs and the When one equipment transmission data, the second equipment can during the AW of CBAP by the second frequency range of second transceiver to the first equipment Declaration service indication message (Announcement Traffic Indication Message, ATIM) frame is sent, to notify the One equipment needs to transmit data.So when second switch state of the 4th switch indication field instruction in DTI is not necessarily to open When opening state, the first equipment may close second transceiver in DTI, but the second transmitting-receiving is opened during the AW of each CBAP Device detects the ATIM frame whether the second equipment sends by second transceiver.
Wherein, the second equipment is orientation in such a way that the second frequency range of second transceiver sends ATIM frame to the first equipment Sending method, so-called directive sending mode refer to that the second equipment negotiates sector with the first equipment in advance, which sets including first Standby, the second equipment sends ATIM frame into the sector by the second frequency range of second transceiver.But it is somebody's turn to do when the first equipment removes Behind sector, the first equipment may not receive the ATIM frame of the second equipment transmission by second transceiver.In order to solve this problem, It referring to fig. 2-8, can also include that third indicating unit or the second equipment can be generated and indicates including third in the first data frame 4th data frame of unit simultaneously sends the 4th data frame to the first equipment, and third indicating unit is used to indicate first transceiver in BI DTI include at least one AW in switch state.
Wherein, the second equipment can also send ATIM frame, and ATIM to the first equipment by the first frequency range during AW The sending method of frame is omnidirection sending method.In this way, including if third indicating unit is used to indicate first transceiver in DTI AW in switch state be open state, then the first equipment opens first transceiver during AW, is connect by first transceiver The ATIM frame for receiving the transmission of the second equipment avoids missing the ATIM frame of the second equipment transmission.
It referring to fig. 2-8, include third indicating unit in the frame main body of the first data frame, third indicating unit includes unit mark Character learning section, length field and content field.Unit marks field carries the identification information for identifying third indicating unit, content Field includes at least one sub- content field, every sub- content field at least one sub- content field and one in DTI A AW is corresponding, which is used to indicate switch state of the first transceiver in its corresponding AW.
The sub- content field can occupy the length of one or more bits.For example, it is assumed that the sub- content field occupies one A bit, the sub- content field carry bit 1, indicate sub- content field instruction first transceiver the opening in its corresponding AW Off status is open state, which carries bit 0, indicates the sub- content field instruction first transceiver in its correspondence AW in switch state be in off state；Alternatively, the sub- content field carries bit 0, sub- content field instruction the is indicated Switch state of one transceiver in its corresponding AW is open state, which carries bit 1, indicates the sub- content Field indicates that switch state of the first transceiver in its corresponding AW is in off state.
Optionally, the first data frame further includes indicating bit, which is used to indicate whether the first equipment is referred to using third Show unit.
It referring to fig. 2 include indicating bit in the frame main body of -9 first data frames.Indicating bit can occupy one or more bits Length.For example, it is assumed that one bit of the instruction bit occupancy, which carries bit 1, indicates that indicating bit instruction first is set Standby to use third indicating unit, which carries bit 0, indicates that the indicating bit indicates that the first equipment is single without using third instruction Member；Alternatively, the indicating bit carries bit 0, indicate that the indicating bit indicates the first equipment using third indicating unit, which takes Band bit 1 indicates that the indicating bit indicates the first equipment without using third indicating unit.
Step 202: the second equipment sends the first data frame to the first equipment.
Step 203: the first equipment receives the first data frame, indicates BI according to the switch instruction information in first data frame At least one period in switch state, at least one period start or close first transceiver and/or second transmitting-receiving Device.
Specifically, the first equipment can extract switch instruction information from the first data frame, from switch instruction information Determine each period of BI corresponding switch indication field.In the initial time in each period of BI respectively according to each period It is corresponding switch indication field instruction first switch state open or close first transceiver, and/or respectively according to it is each when The phase second switch state of corresponding switch indication field instruction opens or closes second transceiver.
For example, determining the corresponding first switch indication field of BTI of BI, A- from the switch instruction information of the first data frame The corresponding second switch indication field of BFT, the corresponding third switch indication field of ATI and the corresponding 4th switch instruction word of DTI Section.In BTI, the first switch state that the first equipment is indicated according to first switch indication field opens or closes the first transmitting-receiving Device, and/or second transceiver is opened or closed according to the second switch state that first switch indication field indicates.Similarly, in BI A-BFT, ATI and DTI open or close first transceiver and second transceiver in a manner described.
If the 4th switch indication field is also subdivided into the first subfield and the second subfield, each in the DTI In CBAP, the first switch state that the first equipment is indicated also according to the first subfield opens or closes first transceiver, and/or, Second transceiver is opened or closed according to the second switch state that the first subfield indicates.In each SP in the DTI, first is set The standby first switch state according to the instruction of the second subfield opens or closes first transceiver, and/or, referred to according to the second subfield The second switch state shown opens or closes second transceiver.
Wherein, it should be noted that switch indication field corresponding for any one period of BI, when the switch indicates word When the first switch state and second switch state of section instruction use the first above-mentioned combination, switch indication field instruction First switch state be can be with open state or not necessarily open state, the second switch state of the second transceiver of instruction are It can be with open state or not necessarily open state.
So if the first switch state of switch indication field instruction is that can be existed with open state, the first equipment First transceiver can be opened according to the first switch state of instruction in the period, received or sent using first transceiver After data, first transceiver can be closed or continue starting first transceiver.If the first of switch indication field instruction opens Off status is not necessarily open state, then the first equipment can close first according to the first switch state of instruction within the period Transceiver can open first transceiver when needing to send or receive data using first transceiver, send or receive First transceiver can be closed after data；Alternatively, whether the first equipment can be decided in its sole discretion within the period opens or closes One transceiver.
Similarly, if the second switch state of switch indication field instruction is that can be existed with open state, the first equipment Second transceiver can be opened according to the second switch state of instruction in the period, received or sent using second transceiver After data, second transceiver can be closed or continue starting second transceiver.If the second of switch indication field instruction opens Off status is not necessarily open state, then the first equipment can close second according to the second switch state of instruction within the period Transceiver can open second transceiver when needing to send or receive data using second transceiver, send or receive Second transceiver can be closed after data；Alternatively, whether the first equipment can be decided in its sole discretion within the period opens or closes Two transceivers.
When the first switch state and second switch state of switch indication field instruction use above-mentioned second of combination side When formula, the first switch state of the instruction of the switch indication field is certain open state or certain closed state, the of instruction The second switch state of two transceivers is certain open state or certain closed state.
So the first equipment exists if the first switch state of switch indication field instruction is certain open state First transceiver is opened according to the first switch state of instruction in the entire period.If the first of switch indication field instruction Switch state is certain closed state, then the first equipment closes first according to the first switch state of instruction within the entire period Transceiver.
Similarly, if the second switch state of switch indication field instruction is certain open state, the first equipment exists Second transceiver is opened according to the second switch state of instruction in the entire period.If the second of switch indication field instruction Switch state is certain closed state, then the first equipment closes second according to the second switch state of instruction within the entire period Transceiver.
When the first switch state and second switch state of switch indication field instruction use the third above-mentioned combination side When formula, the first switch state of the instruction of the switch indication field be certain open state, can with open state, centainly close shape State or not necessarily open state, the second switch state of the second transceiver of instruction be certain open state, can with open state, Certain closed state or not necessarily open state.
So if the first switch state of switch indication field instruction is that can be existed with open state, the first equipment First transceiver can be opened according to the first switch state of instruction in the period, received or sent using first transceiver After data, first transceiver can be closed or continue starting first transceiver.If the first of switch indication field instruction opens Off status is not necessarily open state, then the first equipment can close first according to the first switch state of instruction within the period Transceiver can open first transceiver when needing to send or receive data using first transceiver, send or receive First transceiver can be closed after data；Alternatively, whether the first equipment can be decided in its sole discretion within the period opens or closes One transceiver.If the first switch state of switch indication field instruction is certain open state, the first equipment is entire First transceiver is opened according to the first switch state of instruction in the period.If the first switch of switch indication field instruction State is certain closed state, then the first equipment closes the first transmitting-receiving according to the first switch state of instruction within the entire period Device.
Similarly, if the second switch state of switch indication field instruction is that can be existed with open state, the first equipment Second transceiver can be opened according to the second switch state of instruction in the period, received or sent using second transceiver After data, second transceiver can be closed or continue starting second transceiver.If the second of switch indication field instruction opens Off status is not necessarily open state, then the first equipment can close second according to the second switch state of instruction within the period Transceiver can open second transceiver when needing to send or receive data using second transceiver, send or receive Second transceiver can be closed after data；Alternatively, whether the first equipment can be decided in its sole discretion within the period opens or closes Two transceivers.If the second switch state of switch indication field instruction is certain open state, the first equipment is entire Second transceiver is opened according to the second switch state of instruction in the period.If the second switch of switch indication field instruction State is certain closed state, then the first equipment closes the second transmitting-receiving according to the second switch state of instruction within the entire period Device.
Wherein, it should be understood that in order to carry out wave beam training to second transceiver, the instruction of first switch indication field exists Second switch state and second switch indication field in BTI indicate that the second switch state in A-BFT may be open Open state.So the first equipment opens the second transmitting-receiving according to the second switch state of first switch indication field instruction in BTI Device, and wave beam training, and the second switch indicated in A-BFT according to second switch indication field are carried out to second transceiver State still opens second transceiver, and continues to carry out second transceiver wave beam training.
Wherein, first switch indication field instruction BTI in first switch state can be open state or closed state, First switch state of the second switch field instruction in A-BFT can be open state or closed state.When first switch refers to Show that first switch state and second switch indication field of the field instruction in BTI indicate the first switch state in A-BFT When being open state, the first equipment opens first according to the first switch state of first switch indication field instruction in BTI Transceiver, and wave beam training is carried out using first transceiver auxiliary second transceiver, and refer in A-BFT according to second switch Show that the second switch state of field instruction still opens first transceiver, and using first transceiver continue to assist second transceiver into Traveling wave Shu Xunlian.
In order to distribute the DTI each period of the day from 11 p.m. to 1 a.m phase for including in ATI, so third switch indication field instruction is the second of ATI Switch state can be open state, and such first equipment can switch the second of indication field instruction according to third in ATI Switch state opens second transceiver, pass through second transceiver and the first equipment progress information exchange and distribute that DTI includes it is each The period of the day from 11 p.m. to 1 a.m phase.
Wherein, it should be understood that each CBAP of referring to fig. 2-10, DTI includes AW, when the second equipment needs and first When equipment transmission data, the second equipment sends ATIM frame, Lai Tongzhi first to the first equipment to by the second frequency range during AW Equipment.So first sets when second switch state of the 4th switch indication field instruction in DTI is not necessarily open state It is standby that second transceiver may be closed in DTI, but second transceiver is opened during the AW of each CBAP, pass through second transceiver Detect whether the second equipment sends ATIM frame.Referring also to Fig. 2-10, during AW, if the first equipment passes through second transceiver The ATIM frame for receiving the transmission of the second equipment shows that the first equipment needs the second equipment transmission data, then the first equipment continues out Second transceiver is opened, the data of the second equipment transmission are received by second transceiver or sends data to the second equipment, and is being connect Second transceiver is closed after receiving or having sent data.During AW, if the first equipment is not received by the transmission of the second equipment ATIM frame, then at the end of AW the first equipment close second transceiver.
Optionally, second transceiver operation is closed after having received or sent data for the first equipment, referring to fig. 2-10, It in actual implementation can be with are as follows:
