Embodiment
Now, will specify the preferred embodiments of the present invention, accompanying drawing illustrates its example.In institute's drawings attached, as long as maybe, identical or similar part represented with regard to utilizing same Ref. No..
Fig. 5 illustrates the example of mac header.As shown in Figure 5, mac header comprises " type " field of utilizing 6 bit representations.In addition, according to the bit map type, " type " field can be represented six (6) individual different sub headers.These dissimilar sub-headers can be attached to the back of mac header, and in this " type " field, can indicate the sub-header of particular type.Sub-header is planted in this field indication six (6), and the size of each sub-header is 2 bytes.
Table 1 illustrates the example of six (6) kind sub-headers.
| Type bit | Value |
| #5 highest significant position (MSB) | |
| #4 | |
| #3 | Expand type and point out whether current assembling or segmentation sub-header are expanded 1= |
| #2 | |
| #1 | Assembling |
| #0 least significant bit (LSB) | Down link: FAST-FEEDBACK distributes the sub-header up link: |
As shown in table 1, there is the sub-header utilize six types that highest significant position (MSB) #5 representes to least significant bit (LSB) #0.The sub-header that can indicate each type is to exist or do not exist.More particularly, " 1 " perhaps the type bit of " 0 " represent to exist or do not exist particular header respectively.
For example, if indication " type " position #5 is " 1 ", then MAC PDU comprises the mesh sub-header.That is,, node identifier (node ID) is given and each mobile radio station (MS), to discern each MS in mesh pattern.For this reason, can the mesh sub-header node ID be offered each MS.If indication " type " position #4 is 1, then MAC PCU comprises that expanding the assembling sub-header perhaps expands the segmentation sub-header.If point out that respectively " type " position # 2 and " type " position # 1 are " 1 ", then the grouping PDU corresponding to the user is mapped to MAC PDU payload.In addition, through mac header and cyclic redundancy check (CRC) are appended on it, form MAC PDU.
At last, the application of " type " position # 0 is sent different with downlink transmission to up link.If indication " type " position # 0 is " 1 ", then MAC PDU comprises quick feedback allocation sub-header.At this, the feedback allocation sub-header is positioned at the end of all sub-headers fast.In order to receive value of feedback from this MS, utilizing fast, the feedback sub-header distributes (respectively) resource and feedback information type on the feedback channel (for example, channel quality indicating channel).
Table 2 illustrates the example of quick feedback allocation sub-header.

As shown in table 2, the feedback allocation sub-header utilizes " allocation offsets " to distribute the channel quality indicating channel (CQICH) that utilizes fast feedback channel information word (IE) expression fast, to send feedback information.At this, can represent to distribute CQICH with the mode of timeslice.In addition, utilize " feedback kind ", select the feedback information type.After this MS received this quick feedback allocation sub-header, this MS can utilize this value of feedback request to change to multiple-input and multiple-output (MIMO) pattern, perhaps changes to displacement patterns.
For up link, if indication " type " position # 0 is " 1 ", then this MAC PDU comprises permission management sub-header.Utilize this permission management sub-header to transmit and the relevant information of management uplink resource.In addition, can also change to use and grant the management sub-header according to the sub-header type.According to COS, use airborne request, bandwidth steal scheme and polling scheme, the distribution locations bandwidth on demand.
As shown in Figure 5, mac header comprises that six keep the position, and each length that keeps the position is respectively 1.At this, can utilize two arbitrary information that strengthen quick feedback allocation sub-header that comprise that keep the position.In other words, can utilize the reservation position to indicate whether to have added and strengthen quick feedback allocation sub-header.
If indicating this reservation position is 1, then mac header comprises the information that has the quick feedback allocation sub-header of enhancing, as what select, is " 0 " if indication keeps the position, and then this mac header does not comprise any information that strengthens quick feedback allocation sub-header.
Table 3 illustrates the example that strengthens quick feedback allocation sub-header.

Based on table 3, strengthen quick feedback allocation sub-header packet is sent to this MS.In addition, utilize, strengthen quick feedback allocation sub-header request feedback about the information of transmitting channel and (respectively) weighted value of antenna.At this, can ask additional information, for example, send the method for feedback information.
In table 3, can utilize " allocation type " field to select to send the method for feedback information.For example, if " 0 " expression " allocation type " field, then this MS utilizes fast feedback channel to send feedback information.In this case, utilize " allocation offset " field to represent the address of fast feedback channel, and utilize " CQICH_num " field to confirm to be used to send the quantity of the timeslice of this feedback information.
In addition, utilize " feedback type " field to represent the content of feedback information.For example, if BS uses two antennas, then this BS can ask the weighted value corresponding to first antenna and second antenna, distributes two timeslices simultaneously.Then, utilize the timeslice of distributing, this MS can send the weighted value of first antenna and the weighted value of second antenna.
In addition, can utilize " frame offset " that the information that should when send this feedback information about this MS is provided.That is, after this MS received sub-header, this MS can perhaps send feedback information after specific frame number after specific period.
Alternatively, if " 1 " expression " allocation type " field, then this MS utilizes mac header to send this feedback information.At this, utilize " Duration " field that the information about assigned radio resource on the up link is provided, and utilize the type of " feedback type " expression feedback information.
Table 4 is the examples corresponding to the feedback information of " feedback type " field value.

As stated, if " 1 " expression " feedback type " field, then this MS receives and strengthens quick feedback allocation sub-header, then, through this mac header, utilizes the uplink radio resources of distributing to send feedback information.
Fig. 6 is another example that mac header is shown.As shown in Figure 6, this mac header comprises extended sub-header form (ESF) field, with further expression extended sub-header group.That is, the ESF field value is set to " 1 ", then the extended sub-header group is arranged between the sub-header of six types that mac header and utilization " type " field represent (being right after after this mac header).Alternatively, the extended sub-header group is between this sub-header and payload.After this, term " extended sub-header " can exchange with term " sub-header group " and use.
Fig. 7 illustrates the example of MAC PDU.As shown in the drawing, this MAC PDU comprises: mac header 71, ESF 72, sub-header 73, payload 74 and CRC 75.ESF 72 can be between mac header 71 and sub-header 73, and can confirm the length of ESF 72 according to additional sub-header quantity.As what select, ESF 72 can appear at or be attached to sub-header 73 back.
In mac header, the value that this BS can the ESF field is set to " 1 ", so that will between mac header and sub-header, exist ESF to notify this MS.In addition, should not encrypt, yet this MS can utilize the CRC that is positioned at this PDU afterbody to carry out error detection operation ESF.
Fig. 8 is the sketch map that the structure of extended sub-header group is shown.As shown in Figure 8, the extended sub-header group comprises: extended sub-header length field 81 is used to provide the total length of extended sub-header group; Keep bit field 82; Extended sub-header type field 83; And extended sub-header main body 84.Should be preferably with 8 bit representation extended sub-header length fields, and preferably be the total length of unit representation extended sub-header with the byte.At this, can utilize maximum 27 byte representation total lengths.In addition, extended sub-header is at most 128 bytes.
Table 5 is examples of extended sub-header type.
