Description

The indicating means of resource allocation information and device

Technical field

The present invention relates to the communications field, in particular to a kind of indicating means of resource allocation information and device.

Background technology

At present, use WLAN (Wireless Local Access Network, referred to as WLAN) with more people Enter row data communication, wlan network load is also constantly increasing, Institute of Electrical and Electric Engineers industrial specification IEEE 802.11 groups, successively define the series of standards such as IEEE 802.11a/b/g/n/ac to meet ever-increasing communication requirement, Being directed to these standards improve 802.11 technology to improve greatest physical layer transfer rate or network maximum throughput more. But, increasing with number of users, the efficiency of wlan network occurs the trend being decreased obviously, and improves merely speed This problem can not be solved, therefore, the related efficient WLAN of working group's establishment (High Efficiency WLAN, Referred to as HEW) group is devoted to solving wlan network efficiency, especially dense deployment scene and outdoor scene Network efficiency.HEW group is IEEE 802.11ax group, and therefore the standard of HEW is also referred to as 802.11ax mark Accurate.

WLAN in evolution process, bandwidth from the 20MHz of initial 802.11a/g, to 802.11n maximum 40MHz, To essential bandwidth 80MHz of maximum of 802.11ac, maximum optional bandwidth is 160MHz.The bandwidth of HEW is basic at present On think as 802.11ac.Under conditions of bandwidth is constant, the target of HEW group is an up at least 4 times biographies The handling capacity of system network, (Orthogonal Frequency Division Multiple Access, orthogonal frequency is many for OFDMA Location access) and MU-MIMO (Multi-User Multiple Input Multiple Output, multiuser MIMO) technology be The crucial guarantee of performance boost.

The introducing of OFDMA technology makes multiple users frequency division multiplexing over the whole width, can more preferably utilize frequency between user The result that rate selects improves frequency efficiency, and can reduce the ratio that the competitive resource expense of parcel transmission accounts for whole transmission, Improve time availability.Traditional WLAN technology does not have OFDMA technology, is introduced into up-downgoing OFDMA in HEW.

The multilamellar of MIMO is given multiple users by MU-MIMO, direct utilization space multiplex technique improve the time and The utilization rate of frequency.802.11ac is descending to have been introduced into MU-MIMO, is introduced into up MU-MIMO in HEW.

The frequency resource allocation of same amount of time is given multiple users by OFDMA technology, needs to indicate each with schedule information The resource of user., 160MHz at most will support 32 users taking the resource allocation granularity of 5MHz as a example.HEW The minimum bandwidth granularity that group determines is about 2MHz.Number of users is many, and resource allocation supports that multiple granularities all can cause Schedule information expense increases.

In the related, Fig. 1 is the frame structure schematic diagram in correlation technique, as shown in figure 1, including traditional frame head 3 parts L-STF, L-LTF, L-SIG, are followed by the SIG part of HEW, including HE-SIG-A and HE-SIG-B, It is followed by HE-STF and HE-LTF, be finally the data division of HEW.Wherein HE-LTF has determined that multi-user is many It is alignment between subchannel, that is, the time point of beginning and end is identical.And HE-STF is also alignment, show HE-SIG-B is also required to time domain alignment.
