In existing wireless communications system, schedule information is as most crucial Node B (NodeB, base station) reference information of dispatching, be to send to Node B by terminal, be used to Node B to observe the required system resource total amount of terminal and the actual system resource total amount that maybe can use of using of terminal with a better visual angle.
Schedule information is positioned at processes enhancement type special channel (Enhanced Dedicated Channel, the afterbody of the protocol Data Unit of medium access control entity abbreviation E-DCH), its content is the buffer status renewal value that the new data after enhanced transport format Resource selection process transmit.Referring to Fig. 1, scheduling information frame is comprised of 4 territories.Wherein, least significant bit (bit stream receiving at first) is the rightmost bit in Fig. 1; Highest significant position is the leftmost bit in Fig. 1.
As shown in Figure 1, existing schedule information frame structure comprises following 4 territories:
1) Logic Channel Identifier of limit priority
" Logic Channel Identifier of limit priority " territory clearly identifies the highest priority logical channel of data available.If a plurality of logic channels all in limit priority, take the high level cache of report correspondence the sign of that logic channel of (being that buffer memory free space is maximum) so.
The length in " Logic Channel Identifier of limit priority " territory is 4 bits.
2) total enhancement type special channel buffer status
" total enhancement type special channel buffer status " domain identifier goes out the total amount of data available of all logic channels of leap of radio resource control layer requirement report." total enhancement type special channel buffer status " territory indicates the data total amount for transmitting and retransmitting at wireless chain control layer, take byte as digit.
If configured the medium access control entity of processing enhancement dedicated channel, as MAC-i/is (medium access control entity i/ medium access control entity is), this territory also comprises the data total amount that can be used in MAC-i/is segmentation entity sends.
Radio link control entity (Radio LinkControl when medium access control entity and affirmation mode, be called for short RLC) be associated, this territory also comprises the data of the control protocol data cell being sent out, and the data of the wireless link control protocol data cell outside wireless link is controlled send window.
In addition sent, but by opposite end entity, do not confirmed that in the negative the data of the wireless link control protocol data cell of (NACK) are not included in this territory.
The length in " total enhancement type special channel buffer status " territory is 5 bits.
3) buffer status of the logic channel of limit priority

In the prior art, included 4 domain informations of schedule information frame structure are comparatively simple, are merely able to meet most basic scheduling mechanism the most basic needed information, and Node B has been merely able to the most basic scheduling feature according to this information getting.
By the design of existing scheduling information frame, cannot meet the demand of application scenes.For example, when using two ZAP (this technology makes terminal to send data on two carrier waves, thereby uplink data rate is doubled), if use schedule information frame structure of the prior art, there is following problem:
A) highest priority logical channel of data available has only been pointed out in " Logic Channel Identifier of limit priority " territory, but Node B cannot know this logic channel and be carried on which carrier wave, and each highest priority logical channel of carrying on each carrier wave specifically which.Although there is the information in " Logic Channel Identifier of limit priority " territory, Node B still cannot be learnt the concrete condition on corresponding bearing carrier wave, cannot determine this carries out new scheduling controlling or on two carrier waves, all carries out all not carrying out on new scheduling controlling or two carrier wave new scheduling controlling on which carrier wave.If must carry out scheduling controlling, Node B is merely able to carry out blind control, cause making full use of system resource and terminal power, to such an extent as to cannot provide the optimal scheduling under coupling current network performance and terminal disturbed condition, under extreme case, will cause power ramp unreasonable, disturb too high, user capacity reduces, and terminal sends that data effective speed reduces and the catastrophic effect such as go offline.
B) " buffer status of the logic channel of limit priority " territory, same, because this territory is the amount of available data indicating by the logic channel of " Logic Channel Identifier of limit priority " territory indication, so have the described same problem of above-mentioned A.Node B cannot know the indicated data volume in this " buffer status of the logic channel of limit priority " territory sends being carried on which carrier wave, and the indicated data volume in " buffer status of the logic channel of the limit priority " territory of carrying on each carrier wave is specifically how many.Although there is the information in " buffer status of the logic channel of limit priority " territory, Node B still cannot be learnt the concrete condition on corresponding bearing carrier wave, cannot determine this carries out new scheduling controlling or on two carrier waves, all carries out all not carrying out on new scheduling controlling or two carrier wave new scheduling controlling on which carrier wave.If must carry out scheduling controlling, Node B is merely able to carry out blind control, cause making full use of system resource and terminal power, to such an extent as to cannot provide the optimal scheduling under coupling current network performance and terminal disturbed condition, under extreme case, will cause power ramp unreasonable, disturb too high, user capacity reduces, and terminal sends that data effective speed reduces and the catastrophic effect such as go offline.
C) " terminal power clear space " territory indicates the ratio of the code power of terminal maximum transmit power and corresponding Dedicated Physical Control Channel, and the code power of the Dedicated Physical Control Channel of each carrier wave is different.Node B cannot know that this ratio of " terminal power clear space " territory indication is relatively single carrier wave and is which carrier wave so, the ratio after still two carrier waves consider.Like this, although there is the information in " terminal power clear space " territory, Node B still cannot accurately be learnt the concrete power headroom situation on corresponding each bearing carrier wave, causing in fact Node B is cannot more use terminal power headrooms to carry out the more high-power data of higher rate to transmit, and the speed of namely terminal transmission data cannot promote; Or in fact Node B possible errors ground is used terminal power headrooms to carry out the more high-power data transmission of higher rate, and the speed of namely terminal transmission data is promoted by mistake.Any situation no matter, Node B all cannot make full use of system resource and terminal power, to such an extent as to cannot provide the optimal scheduling under coupling current network performance and terminal disturbed condition, under extreme case, will cause power ramp unreasonable, disturb too highly, user capacity reduces, and terminal sends that data effective speed reduces and the catastrophic effect such as go offline.
