Description
Technical field
The present invention relates to TD SDMA (TD-SCDMA, Time Division SynchronousCode Division Multiple Access) technology, refer to the indicating means of a kind of multi-carrier high-speed uplink packet access (HSUPA, high speed uplink packet access) power limited, system and terminal especially.
Background technology
In HSUPA system, user terminal (UE, User Equipment) holds the transmitting power of enhanced uplink physical channel (E-PUCH, Enhanced Uplink Physical Channel) according to following formulae discovery:
(1)P
E-PUCH＝P
e-base+L+β
e。
Wherein, P
e-PUCHfor the transmitting power of E-PUCH; P
e-basefor the closed loop amount that UE and Node B (NodeB) are safeguarded, after receiving transmitting power control (TPC, Transmission Power Control) order, all can increase or reduce certain numerical value Δ at every turn
e-base, Δ
e-basethe size of value is configured by high level; L is path loss, obtains according to the measurement of beacon physical channel; β
ecorresponding selected enhanced transport format combination (E-TFC, Enhanced Transport Format Combination) the biased gain factor of transmission block size, the E-PUCH physical resource of distribution, modulation system and hybrid automatic repeat-request (HARQ, Hybrid Automatic RepeatRequest).
PRX
des_basefor E-PUCH benchmark expectation received power, by radio resource control (RRC, Radio Resource Control) signaling, be set to the interference mean value of enhancement type special channel (E-DCH, EnhancedDedicated Channel) ascending time slot; Step is power control step-size Δ
e-base, configured by high level; TPC
iit is closed-loop power control order.
When carrying out E-TFC and selecting, need the transmitting power P ensureing to calculate
e-PUCHbe less than or equal to user's maximum transmission power and authorization power simultaneously.
E-DCH ascending control channel (E-UCCH, E-DCH Uplink Control Channel) be E-DCH uplink control channel, be mapped in E-PUCH and be used for carrying HARQ relevant information, its content comprises the HARQ process identification (PID) of 2 bits, the re-transmission sequence number (RSN of 2 bits, RetransmissionSequence Number) and the transmission block size determined by E-TFC of 6 bits, as can be seen here, E-UCCH receives mistake and directly can cause correctly connecing and search E-DCH.In HSUPA, E-UCCH transmitting power is identical with the transmitting power of E-PUCH.
In order to improve throughput and the peak rate of system further, multicarrier is introduced HSUPA by 3GPP, this technology can carry out HSUPA transmission on multiple carrier waves of a community (N number of carrier wave), and the up N that can obtain is doubly to the throughput of single carrier HSUPA on the one hand; Also possibility N doubly improves the peak rate of single terminal on the other hand.
In multicarrier (MC-HSUPA, Multi-Carrier HSUPA), schedule information (SI, SchedulingInformation) have employed the form shown in table 1,
Table 1
SI is made up of three parts:
One, Buffer information, comprising:
Highest priority logical channel (HLID, Highest priority Logical Channel), length is 4bits whole E-DCH Buffer state (TEBS, Total E-DCH Buffer Status), and length is 5bits;
Highest priority logical channel Buffer state (HLBS, Highest priority Logical channelBuffer Status), HLBS length 4bits;
UE power residue (UPH, UE Power Headroom): represent UE maximum transmission power and work as β
eequal the power ratio that the 0 UE transmitting power calculated is compared, length is 5bits.
Two, Serving cell and adjacent cell path loss (SNPL, Serving and Neighbour Cell Pathloss): when UE sends data according to the resource of distributing and maximum authorized power, NodeB SNPL estimates the presence of intercell interference produced, and SNPL is carried in the SI that carrier wave reports.SNPL length is 5bits.SNPL1 represents the SNPL1 of carrier wave 1.
Three, SNPL bitmap: represent that in SNPL2 ~ SNPLn, which carries in SI, when the bit that certain carrier wave is corresponding in SNPL bitmap is 0, represent that the SNPL of this carrier wave is not carried in its SI reported, otherwise represent the SNPL carrying this carrier wave in the SI reported.
In multi-carrier HSUPA, scheduling authorization carries out according to each carrier wave, and each carrier wave has a HARQ entity to process transmission and the re-transmission of upstream data, and thus each carrier wave is also independently carry out E-TFC selection course.Because user's maximum transmission power is a definite value, when network authorization power can not meet demanding terminal, appear in the E-PUCH transmitting power sum that each carrier wave in a time slot calculates and be greater than user's maximum transmission power, thus cause user to be not more than user's maximum transmission power with the ascending power sum meeting all carrier waves in a time slot sending the power having to compress some carrier wave when E-PUCH, Here it is so-called power limited.Because E-UCCH transmitting power is identical with E-PUCH power, thus also have compressed the transmitting power of E-UCCH, thus the error probability causing network side to receive E-UCCH increases, the probability directly causing user correctly can not receive E-PUCH increases.
