Background technology
HSUPA (High Speed Uplink Packet Access, High Speed Uplink Packet inserts) has introduced N frequency characteristic in 3GPP, promptly can there be a plurality of frequencies a sub-district, and one of them frequency is the dominant frequency point, and other frequencies are auxilliary frequency.UE (User Equipment, subscriber equipment) is the single carrier operation pattern, and its working frequency points both can be on the dominant frequency point of sub-district also can the auxilliary frequency in the sub-district.The introducing of N frequency has promoted the user capacity of system greatly, and meanwhile N frequency characteristic is also laid a good foundation for introducing the multicarrier characteristic among the HSUPA.The introducing of multi-carrier HSUPA can promote user's up peak rate, and its upstream rate can be descending close with multi-carrier HSDPA, can realize up-downgoing speed symmetry.In addition, with respect to N frequency characteristic, the UE in the multi-carrier HSUPA system can use carrier wave more flexibly.
But the single carrier HSUPA under the N frequency, the introducing of multicarrier characteristic has also brought a lot of problems relevant with multicarrier.To carry be exactly one of them to schedule information under the multicarrier.What current ascending reinforcement system was that single-frequency puts the reflection of schedule information in the up enhancement techniques is the schedule information of UE at this frequency, but after multifrequency point is introduced, because the partial information content difference on each frequency, so need to consider the mode of carrying of schedule information is carried out certain expansion, can carry mode by the schedule information of extended mode to reach UE, be that unit reports with the frequency with information.
Having introduced new transmission channel kinds in up enhancement techniques is E-DCH (ascending reinforced special channel), the data cell of this channel be MAC-e/es PDU (Protocol data unit, Packet Data Unit) (when the configuration be the MAC-es/e entity time) or MAC-i/is PDU (when the configuration be the MAC-is/i entity time).In existing up enhancement techniques, can carry uplink scheduling information (Scheduling Information, be called for short SI) among MAC-e PDU and the MAC-i PDU, MAC-e PDU all has the different modes of carrying with MAC-i PDU, below simply introduces respectively.
When using MAC-e PDU, be illustrated in figure 1 as the schematic diagram that MAC-e PDU carries schedule information SI.Wherein, 1 MAC-e PDU of each TTI (Transmission Time Interval) carrying on each E-DCH channel, this MAC-e PDU can carry the data of multiple business (being logic channel), promptly can carry a plurality of MAC-es PDU, the data of identical logic channel, Pei Zhi MAC-dPDU's (each logic channel all can corresponding a MAC-d entity) is big or small identical simultaneously, then can form a MAC-es PDU, wherein DDI (Data Description Indicator, data description indication) can the characterization logic channel id and the size of each MAC-d PDU.When the needs transmitting scheduling information or when having Padding enough to fill schedule information, then schedule information SI is carried at the end of MAC-ePDU.When only containing schedule information among the MAC-e PDU, as shown in Figure 2.
When using MAC-i PDU, be illustrated in figure 3 as the schematic diagram that MAC-i PDU carries schedule information SI.Wherein, 1 MAC-i PDU of each TTI carrying on each E-DCH channel.Each MAC-i PDU comprises 1 MAC-i head and one or more MAC-is PDU.Each MAC-is PDU comprises one or more MAC-is SDU that belong to same logical channel.Each MAC-is SDU is the MAC-d PDU of a complete or segmentation.MAC-is PDU can be from a plurality of logic channels.When MAC-i PDU had remaining space or needs to send schedule information SI, schedule information was included in the end of MAC-i PDU.When only containing schedule information among the MAC-e PDU, similar with Fig. 2.
As shown in Figure 4, be the structural representation of schedule information SI in the prior art.The cache information that comprises this UE in the schedule information, it comprises TEBS (total buffer memory of UE), HLID (the highest service priority) and HLBS (buffer memory of highest priority traffic), also comprises SNPL (the path loss ratio of this sub-district and adjacent sub-district) and UPH (power headroom) in the schedule information.Dispatch and resource allocation this UE according to the schedule information that UE sends the base station.Wherein, the measurement sub-district that participates in SNPL calculating comprises with UE carries out the identical co-frequency neighbor cell of carrier wave that the HSUPA data send, and comprising the auxilliary frequency sub-district identical in the alien-frequency district with this HSUPA frequency, SNPL value that hence one can see that is the parameter of being separated by with frequency; And, UPH is defined as Pmax/ (Pebase*Pathloss), wherein Pmax is the maximum power that UE sends, Pathloss is the path loss that this UE measures according to broadcast channel, Pebase is the power reference value of safeguarding according to each carrier case, hence one can see that, and Pebase belongs to carrier wave level parameter, and promptly UPH also is a carrier wave level information.Therefore, in schedule information, not only comprise UE class information (cache information), also comprise carrier-grade information (UPH and SNPL).
Yet, because existing up enhancement techniques is only supported the single carrier transmitting capacity, therefore present UE can only report the carrier-grade information of a carrier wave, like this for the scene of multi-carrier HSUPA, the send mode of present schedule information can only react the UE class information of UE and the carrier-grade information of certain carrier wave, and can not react the carrier-grade information of each carrier wave, the base station can only be according to other carrier waves of carrier-grade message scheduling of certain carrier wave like this, thereby cause the inaccurate problem of scheduling.
