Description

The user is carried out the method for uplink scheduling and up-downgoing combined dispatching
Technical field
The present invention relates to the communications field, relate in particular to a kind of method of the user being carried out uplink scheduling and up-downgoing combined dispatching.
Background technology
Insert in the Release99 protocol version the earliest of (WCDMA) technology in Wideband Code Division Multiple Access (WCDMA), the carrying of uplink and downlink business all is based on dedicated channel, and the message transmission rate that can reach is 384Kbps.Along with the user is more and more higher to the high data transfer rates demand, the WCDMA standard formulation is organized and has been released down high-speed data bag access technology and up-high speed data packet access technique subsequently successively, peak rate up to 14.4Mbps and 5.76Mbps can be provided respectively, and spectrum efficiency has also obtained very big raising.
Wherein the high-speed down data bag inserts (HSDPA) technology, in being incorporated into the version of 3GPPRelease5 in 2002, the main feature of HSDPA system comprises: the short frame that adopts 2ms, adopt mixed self-adapting repeat requests (HARQ) technology and Adaptive Modulation and Coding (AMC) technology in physical layer, introduce the 16QAM high order modulation and improve the availability of frequency spectrum, realize the shared channel scheduling of each UE by sign indicating number branch and time-division.Wherein, the HARQ technology has adopted the SAW agreement, require NodeB to send data to UE after, obtains reply data by the ACK/NACK that obtains UE feedback and whether correctly receive, and then decision is data retransmission or New Development data.Wherein, the channel quality indicator (CQI) that AMC specification requirement UE feeding back downlink is measured is so that the code rate and the transformat of the descending HSDPA data of decision NodeB side.
The HSDPA high-speed down link data packet access technique has increased by two physical channels descending, and one is the HS-SCCH channel, the required signaling of carrying demodulation companion data channel HS-PDSCH; Another is the HS-PDSCH channel, carrying user's data information.The HSDPA high-speed down link data packet access technique is at a up physical channel HS-DPCCH, the information A CK/NACK of this channel bearing feeding back downlink Frame HS-PDSCH reception correctness, perhaps the channel quality indication (CQI) information CQI of having increased.
In order to realize downlink user sharing to HSDPA down channel HS-SCCH and HS-PDSCH, the base station need be according to the descending sign indicating number resource of current area and the channel quality indicator (CQI) information of downlink power resources and reporting of user, adopt the relative fair scheduling algorithm that generally uses, determine the user that each 2ms Transmission Time Interval need be dispatched, and suitable descending sign indicating number resource and the power resource of distributing user.
The high speed uplink packet inserts (HSUPA) technology, in being incorporated into the version of 3GPPRelease6 in 2004, the main feature of system comprises: adopt short frame of 2ms or 10ms frame, adopt HARQ mixed self-adapting repeat requests in physical layer, up base station fast dispatch technology has improved up spectrum efficiency.In order to realize the high-efficiency transfer of user uplink data, the HSUPA specification requirement is newly-increased up two physical channels of user, one is the up enhancing dedicated data transmission channel (E-DPDCH) of transmission data, another is the up enhancing Dedicated Control Channel (E-DPCCH) of transmission accompanied by physical layer signaling, and the latter provides the signaling of following for the former demodulation.In order to control user's uplink speed, down channel has increased absolute grant channel (E-AGCH) and relative authorization channel (E-RGCH), absolute grant channel only exists in service wireless connections sub-district, be used to the peak transfer rate of indicating user uplink to transmit, the frequency ratio of adjusting is lower; The relative authorization channel can exist in service wireless connections and non-service wireless connections sub-district, is used to indicate the user to adjust uplink speed by certain step pitch, and the frequency ratio of adjustment is higher, reaches as high as every 2ms once.Whether correct down channel also increased the channel (E-HICH) of indicating the transmission of up process data, and whether the data that are used to tell the user to send are correct, if incorrect, the user will initiate re-transmission, otherwise the user sends new data.
The high speed uplink packet inserts (HSUPA) technology and down high-speed data bag access (HSDPA) is not both: user uplink sign indicating number resource and power resource are that each user exclusively enjoys, the up-high speed packet inserts (HSUPA) and need not dispatch at up sign indicating number resource and power resource, but the certain transmission rate of up each user can produce corresponding interference at the base station receiving terminal, the base station can ensure user's demodulation performance in the interference range that allows, surpass the scope of setting but disturb, just may make certain user's demodulation performance to ensure, so the basic principle of up-high speed packet access (HSUPA) base station scheduling is the interference level that control and permission user bring at the base station receiving terminal.The up fast dispatch in base station is according to the interference level and setting thresholding of current area, determine the transmitted data rates that user uplink allows, and when interference level is too high, can reduce the message transmission rate of user uplink fast, make uplink interference in the target zone of setting.
Prior art one related to the present invention:
The down high-speed data bag inserts the base station fast dispatch algorithm of (HSDPA) technology according to user's downlink data buffer queue priority, capacity, send data stand-by period length, information such as channel quality indicator (CQI) are carried out priority users queuing to downlink user, the user that priority the is high transmission downlink data that just can be scheduled.The user who is scheduled will allocation of downlink sign indicating number resource and power resource, and definite format of user data.The base station scheduling algorithm of down high-speed data bag access (HSDPA) technology has only been considered the distribution and the use of downlink resource, does not consider the uplink service situation.
The up-high speed packet inserts the base station fast dispatch algorithm of (HSUPA) technology according to gross power in the bandwidth of current reception, determine uplink interference level, and and the target set receive that gross power compares in the bandwidth, judge that according to remaining surplus up user allows the interference level that increases.The base station is according to user's upstream rate request, information such as indication information of whether being satisfied with and data re-transmission number of times, determine the user and the higher uplink bit rate of adjustment, and predict the interference level that adjusted transmission rate increases for the base station receiving terminal, make that total uplink interference level that base station cell receives is below target value set after the up fast dispatch.The up-high speed packet inserts the base station scheduling algorithm of (HSUPA) and has only considered uplink interference level, does not consider user's downlink business situation.
By the technical scheme of prior art as can be seen, there is following shortcoming in it:
The base station fast dispatch algorithm of down high-speed data bag access (HSDPA) is not considered the judgment condition of up-high speed packet access dispatching, the two separately independent scheduling and design.Like this, exercise instantly when inserting with high speed packet, the up up-high speed packet that can use usually inserts, and the two is dispatched respectively same subscriber, causes the waste of interface-free resources; And, along with adopting in the future orthogonal frequency modulation (OFDM) and multiple-input and multiple-output (MIMO) antenna technology, the number of users scale of base station cell support also can strengthen, may surpass more than 400, many community users scheduling etc. are handled resource requirement than higher, if the method for independent scheduling is carried out to professional user is all arranged in the uplink and downlink link in the base station in the employing prior art, will cause the bigger waste of resource.
