A kind of method and relevant device for sending Frame
Technical field
The present invention relates to the communications field, more particularly to a kind of method and relevant device for sending Frame.
Background technology
In WLAN (Wireless local Access Network, WLAN in), with reference to shown in Fig. 1, access point (Access Point, AP) it is responsible for and multiple website (Station, STA two-way communication, i.e. AP) are carried out and sends downlink data to STA, or receive the upstream data from STA.
It is existing based on OFDM (Orthogonal Frequency-Division Multiplexing, OFDM) WLAN (the Wireless local Access Network of technology, WLAN) standard by progressively evolution 802.11a, 802.11n, the versions such as 802.11ac are constituted, at present the normal structures of IEEE 802.11 have had been turned on referred to as high efficiency WLAN (High Efficiency WLAN, HEW wlan standard of new generation) is the standardization effort of 802.11ax, the standard supports orthogonal frequency division multiplexing multiple access (Orthogonal Frequency-Division Multiple Access, OFDMA) technology.Broad-band channel is divided into multiple orthogonal subcarriers by orthogonal frequency division multiplexing multiple access technology in frequency domain, and distributes different subcarriers for different users, so as to the orthogonal multiplex for realizing multiple users is transmitted.
With reference to shown in Fig. 2, introduce the Frame in the physical layer packet structure of 802.11ax, the structure of Frame includes Legacy Short Training Field (Legacy Short Training field, L-STF), traditional long training field (Legacy Long Training field,) and legacy signaling field (Legacy Signal field L-LTF, L-SIG) and its repeat (Repeat Legacy Signal field, RL-SIG) composition field；Afterwards, mid portion is by efficient signaling field A (High Efficiency Signal-A field, HE-SIG-A), efficient signaling field B (High Efficiency Signal-B field, HE-SIG-B), high efficiency short training field (High Efficiency Short Training field,) and high efficiency long training field (High Efficiency Long Training field HE-STF,) etc. HE-LTF field, is finally data field.Wherein, data field is used for data transfer, the fields such as L-SIG, RL-SIG, HE-SIG-A and HE-SIG-B are respectively used to transmit the fields such as different types of physical layer signaling, L-STF, L-LTF, HE-STF and HE-LTF and are then mainly used in the purposes such as receiving terminal timing and Frequency Synchronization, automatic growth control and channel estimation.As shown in figure 3, HE-SIG-A is used for carrying the information that the Basic Service Sets such as bandwidth, AP identifiers (Basic Service Set, BSS) and Overlapping Basic Service Set (Overlapped BSS, OBSS) interior STA can read.
Fig. 2 illustrates AP to be carried out data transmission to multiple STA simultaneously by downlink (Downlink, DL) OFDMA modes using multiple Resource Block.Wherein, several STA can also share same Resource Block, by way of MU-MIMO, carry out data transmission on respective spatial flow.Now, whole bandwidth is divided into multiple Resource Block by AP, and multiple STA are carried out data transmission using multiple Resource Block.In order to allow STA to learn whether oneself is purpose STA；Also need to the physical layer parameter of the position and receiving data for allowing purpose STA to obtain primary data place, AP needs the instruction that resource scheduling information was carried out before distribution Resource Block, for descending multi-user transmission, the resource scheduling information comprising multi-user generally in HE-SIG-B, indicates that multiple STA carry out the reception of data.
Fig. 4 is a kind of possible structures of HE-SIG-B, and it includes PD (HE-SIG-B common) and one by one website domain (HE-SIG-B dedicated).Some public informations that PD is required for reading comprising all purposes STA, such as configured information (the Resource allocation Signaling of resource block assignments, RA Signaling), the schedule information that one by one website domain contains each STA or one group of STA needs reads in same Resource Block.
When transmission bandwidth is more than 20M hertz, preamble portion is required for transmission in each 20M hertz frequency range.It is the copy transmissions on each 20M for L-STF, L-LTF, L-SIG, RL-SIG and HE-SIG-A；It is the transmission structure replicated using part for efficient signaling field part B HE-SIG-B.By taking 80M transmission as an example, the transmission of leading part is specifically as shown in Figure 5.
Can see, HE-SIG-B carries different contents in odd number 20M hertz frequency range and even number 20M hertz frequency ranges, and identical content is carried in odd number 20M hertz frequency ranges, identical content is carried in even number 20M hertz frequency ranges (second 20M hertz frequency range and the 4th 20M hertz frequency range), as shown in Figure 6.HE-SIG-B in note odd number 20M hertz frequency ranges is SIGB-1, and the HE-SIG-B in even number 20M hertz frequency ranges is SIGB-2.The content included in SIGB-1 and SIGB-2, including PD and website domain one by one.SIGB-1 includes the resource indication information (RA signaling) and the schedule information of the user transmitted on first and the 3rd 20M hertz frequency range of first 20M hertz frequency range and the 3rd 20M hertz frequency range.SIGB-2 includes the resource indication information (RA signaling) and the schedule information of the user transmitted on second and the 4th 20M hertz frequency range of second 20M hertz frequency range and the 4th 20M hertz frequency range.For the transmission bandwidth of 20M hertz frequency ranges, only comprising a HE-SIGB (SIGB-1).Transmission bandwidth for 40MHz, comprising SIGB-1 and SIGB-2, but SIGB-1 and SIGB-2 are only indicated and user scheduling information comprising the resource allocation transmission structure in a 20M hertz frequency range, SIGB-1 includes first 20M hertz frequency range (odd number 20M hertz frequency ranges), and SIGB-2 includes second 20M hertz frequency range (even number 20M hertz frequency ranges).
Convenient for record, definition is presented below [1,2,1,2] and represents in Fig. 5, Fig. 6 in HE-SIG-B transmission structures.Order from top to bottom, it is identical with the HE-SIG-B information transmitted in the 3rd 20M hertz frequency range in first 20M hertz frequency range, be designated as " 1 " of first position and the 3rd position in [1,2,1,2], i.e., aforesaid SIGB-1 is represented by " 1 "；It is identical with the HE-SIG-B information transmitted in the 4th 20M hertz frequency range in second 20M hertz frequency range, be designated as " 2 " of first position and the 3rd position in [1,2,1,2], i.e., represent aforesaid SIGB-2 by " 2 ".
But, this [1,2,1,2] structure existing defects in transmitting procedure, when the use in first 20M hertz frequency range and the 3rd 20M hertz frequency range it is more per family, and when number of users is less in second 20M hertz frequency range and the 4th 20M hertz frequency range, the SIGB-1 that this structure is constituted will it is longer than SIGB-2 size a lot, because the end position of HE-SIG-B is identical in different 20M hertz frequency ranges, after having resulted in the SIGB-2 end of transmissions of second 20M hertz frequency range and the 4th 20M hertz frequency range, occur the free time in the frequency range, cause to waste.This waste is caused because HE-SIG-B transmission structures are single, and this single structure can not well adapt to the flexible allocation of the HE-SIG-B under different scenes, under different loads and scheduling, cause the wasting of resources.
If according to the number of users in different 20M hertz frequency ranges, load balancing (load balancing) is done in flexibly pairing, constitutes SIGB-1 and SIGB-2, and the mode still according to [1,2,1,2] is transmitted.For example when first 20M hertz frequency range, number of users is less in 3rd 20M hertz frequency range and the 4th 20M hertz frequency range, and number of users is more in second 20M hertz frequency range, now can be first 20M hertz frequency range, the schedule information of the user of resource indication information and transmission in the 3rd 20M hertz frequency range and the 4th 20M hertz frequency range is combined into SIGB-1, the resource indication information in second 20M hertz frequency range and the user scheduling information structure SIGB-2 of transmission, according to [1, 2, 1, 2] transmission structure, in first 20M hertz frequency range and the 3rd 20M hertz band transmissions SIGB-1, in second 20M hertz frequency range and the 4th 20M hertz band transmissions SIGB-2.But, this transmission structure has a problem that, only transmit in first 20M hertz frequency range and the 3rd 20M hertz frequency range in the resource indication information of the 4th 20M hertz frequency range and the user scheduling information of transmission, and without transmission in the 4th 20M hertz frequency range, AP cannot ensure user in the 4th 20M hertz frequency range first 20M hertz frequency range and the 3rd 20M hertz frequency range channel situation how, how it is disturbed degree, even if flexibly pairing constitutes SIGB-1 and SIGB-2, but still according to [1, 2, 1, 2] structural transmission, or the performance of user in the 4th 20M hertz frequency range can be reduced.
The transmission structure of current HE-SIG-B causes HE-SIG-B transmission means on more than 20M hertz frequency range frequency bands single, it is impossible to adapts to various loading conditions in practice, causes the problem of the wasting of resources.
