Abstract
The invention provides a system and method for configuring a shared-channel neighbour cell of high speed uplink packet access in a multi-carrier system. The method comprises the steps: a wireless network controller configures shared-channel information of multi-carrier high speed uplink packet access (HSUPA) to user equipment and sends the shared-channel information to the user equipment; and the user equipment performs neighbour cell measurement and reports serving and neighbour cell pathloss (SNPL) according to the obtained shared-channel information of the multi-carrier HSUPA. By using the technical scheme of the invention, the user equipment can correctly report the SNPL information when the multi-carrier HSUPA works, therefore, a node base station can be used for distributing proper resource to the user equipment according to the SNPL information so as to improve service rate and reduce interference.
Description
Technical field
The present invention relates to (the Time DivisionSynchronous Code Division Multiple Access of TD SDMA in moving communicating field, be called for short TD-SCDMA) technology, particularly, relate to configuration-system and the method for a kind of TD-SCDMA multicarrier system high speed upstream packet access (High Speed UplinkPacket Access is called for short HSUPA) homogeneous-frequency adjacent-domain.
Background technology
TD-SCDMA enhancing-special uplink channel (Enhanced Uplink Dedicated Channel, being called for short E-DCH) relevant physical channel has: strengthen uplink physical channel (Enhanced Uplink PhysicalChannel, be called for short E-PUCH), strengthen ascending control channel (E-DCH Uplink Control Channel, be called for short E-UCCH), strengthen up channel hybrid automatic repeat-request answering indication signal channel (E-DCHHybrid Automatic Repeat ReQuest Acknowledgement Indicator Channel, be called for short E-HICH), and strengthen up absolute grant channel (E-DCH Absolute Grant Channel, be called for short E-AGCH) etc.
Strengthen multi-upstream access business and be divided into dispatching services and non-scheduling service by the difference of scheduling mode, wherein the resource of non-scheduling service is by radio network controller (Radio Network Controller, be called for short RNC) for UE distributes, the method for salary distribution is with existing dedicated channel allocation mode; And in dispatching services, be that Node B (NodeB) distributes enhanced uplink resource pool by RNC, be single UE Resources allocation by Node B.
In dispatching services, UE needs to report some information with the scheduling of auxiliary Node B, these information are called schedule information SI (Scheduling Information), comprising the path loss metrical information etc. of UE buffer information, power headroom, this community and adjacent cell, have 23 bits.The content of schedule information is depicted as shown l.
Table 1: the content of schedule information
| SNPL | UPH | TEBS | HLBS | HLID |
| (5bits) | (5bits) | (5bits) | (4bits) | (4bits) |
Wherein total buffer state is the sum total of data volume to be sent in UE logic channel buffering area; Highest priority logical channel state is buffer area data volume corresponding to the current highest priority logical channel having data to be sent; Highest priority logical channel ID specifically indicates data highest priority logical channel number to be sent.It is for referencial use that these three parameters are that Node B distributes suitable resource, comprises channel resource and power resource.Service, adjacent cell path loss (Serving and Neighbour Cell Pathloss, be called for short SNPL) provide the reference controlled the interference of adjacent cell for Node B; Uplink power margin is the current available transmitted power of UE.When UE has the E-PUCH resource of mandate, schedule information is sent by E-PUCH channel together with business datum, and when UE with no authorized, SI will send schedule information by E-RUCCH channel.
For multi-carrier TD-SCDMA system, because user can be operated in assistant carrier frequency, therefore the definition of the same frequency in measuring, alien frequencies defines according to the relation of adjacent area dominant frequency point and user job frequency, if that is dominant frequency point in adjacent area is identical with user job frequency be considered as homogeneous-frequency adjacent-domain, if dominant frequency point in adjacent area is different from user job frequency, be considered as alien frequencies adjacent area.SNPL is the measurement to homogeneous-frequency adjacent-domain, but for TD-SCDMA multicarrier system, can not only consider that merely dominant frequency point has been same adjacent area frequently, when auxiliary frequency is identical with user job frequency in adjacent area, also need the measuring object including SNPL in.Whether current RRC agreement has auxiliary frequency identical with current working frequency, as shown in table 2 by system broadcast message with Survey control message informing UE adjacent area:

There is a cell " assistant carrier frequency with frequently instruction " alien frequencies adjacent area in table 2, has the frequency identical with user's current working frequency in the middle of the auxiliary frequency being used to refer to this alien frequencies adjacent area, and by this indicating bit, UE just knows to be needed to measure this adjacent area when calculating SNPL.
For single carrier HSUPA, such indicating bit is no problem, but for multi-carrier HSUPA, UE can send data at multiple carrier frequency, SNPL can be reported at multiple carrier frequency, so will go wrong, this indicating bit mark same frequent point actually with which HSUPA frequency point co-frequency? need to consider this neighborhood path loss in the SNPL information of which HSUPA frequency? homogeneous-frequency adjacent-domain list is also had problems, current homogeneous-frequency adjacent-domain list does not have similar indication field, homogeneous-frequency adjacent-domain just illustrates that the main carrier frequency of adjacent area is identical with UE working frequency points, the auxiliary frequency in adjacent area can not be indicated whether to have the frequency identical with multi-carrier HSUPA frequency.Network side can not get SNPL information accurately, distributes suitable resource, maldistribution of resources by being difficult to UE, may affect quality of service on the one hand, on the other hand, may cause larger interference.
