Description

Signal channel quality measuring method and terminal

Technical field

The present invention relates to the communication technology, be specifically related to a kind of signal channel quality measuring method and terminal.

Background technology

At GSM (Global System for Mobile communications; Global system for mobile communications), GPRS (General Packet Radio Service; GPRS), in the EDGE systems such as (Enhanced Data rates for GSM Evolution, Enhanced Data rates for GSM Evolutions), a TDMA (Time Division Multiple Access; Time division multiple access) frame is divided into 8 time slots; As shown in Figure 1, the identical time slot of each frame is just formed a PDCH (Packet Data Channel, Packet Data Channel).The time slot of distributing to GPRS/EGPRS is called PDCH, and network is a unit with PDCH when allocation of channel resources may.

EGPRS (Enhanced GPRS; Strengthen GPRS) be an enhancing version of GPRS air interface; Also claim EDGE; Be a kind ofly to utilize existing frequency band that existing GSM network is had the mobile network of 3G professional ability is provided wireless technology, its improves the data rate of system and realizes higher bit rate through adopting the 8-PSK modulation technique.

In the EGPRS system, under packet transfer mode, the pattern whether network carries out channel quality measurement and measurement through the assignment messages or the reconfiguration message notice terminal of transmission.After the terminal receives assignment messages, carry out channel quality measurement, and calculate bit error rate and interference measure, give network through EGPRS grouping downlink ack/nack (Ack/Nack) information reporting then according to measurement result according to the network mode designated.Comprise the channel quality reporting field in the EGPRS grouping downlink ack/nack message, this field comprises information such as bit error rate that the terminal calculates and interference measure.Network is through the channel quality of terminal report, the coding of the data block of sending adjusted accordingly, so that transmission performance is optimum.

In the assignment messages or reconfiguration message that network sends, comprise the field of indication link quality measurements pattern, through this field network can indicating terminal report chain drive test amount pattern, following several kinds of situation are arranged:

(1) terminal neither the report time slot interference measure γ value also not report time slot bit error rate measurement BEP (Bit Error Probability, bit error rate) be worth;

(2) terminal only the report time slot interference measure the γ value;

(3) terminal report time slot bit error rate measurement BEP value only;

(4) terminal both the report time slot interference measure γ value, also report time slot bit error rate measurement BEP value.

In EGPRS grouping downlink Ack/Nack message, comprise time slot link quality measurements field, the terminal distributes the single time slot interference on the time slot to measure the γ value or/and single time slot bit error rate measurement BEP value through this field report.Disturb rank I_LEVEL value because interferometry γ value can be scaled through certain corresponding relation, therefore when network requirement terminal report γ value, the terminal is the corresponding I_LEVEL value of report just.

For example, the network requirement terminal is report time slot interference measurement γ value both, again report time slot bit error rate measurement BEP value.If for the time slot of terminal distribution is time slot 0 (TN0), the terminal can report that TN0 goes up MEAN_BEP (Mean Bit Error Probability, average BER) value and the I_LEVEL value under certain modulation system.If a plurality of time slots that have been terminal distribution, then MEAN_BEP value under certain modulation system and I_LEVEL value on each distributed time slot can be reported in the terminal.

For example the measured value on the time slot 0 is reported according to following mode:

{ average BEP value under the GMSK modulation mode on 0|1{0 < GMSK_MEAN_BEP_TN0:bit (the 4)>time slot 0

| 1 < 8PSK_MEAN_BEP_TN0:bit (4)>} } or time slot 0 on average BEP value under the 8PSK modulation mode

With

I_LEVEL value on { 0|1 < I_LEVEL_TN0:bit (4)>} time slot 0

At GERAN (GSM/EDGE Radio Access Network; GSM EDGE Radio Access Network) in the evolution; Adopt time-based quick A ck/Nack message to reduce propagation delay time: promptly through in descending RLC/MAC (Radio Link Control/Medium Access Control, the access control of Radio Link control/medium) data block, carrying the purpose that short bitmap (short bitmap) reaches quick feedback Ack/Nack information.After high level data is sub-divided in the RLC/MAC data block, carry transmission by radio block.Radio block is the base unit of allocation of radio resources and wireless transmission.Each BTTI (Basic Transmission Time Interval, basic Transmission Time Interval) radio block is made up of 4 bursts (Burst) pulse, and is laid respectively at the identical time slot of 4 continuous tdma frames.The BTTI radio block is shown in B1 among Fig. 2, and BTTI radio block B1 is on 4 continuous T DMA frames, and every frame takies 1 time slot, and the TTI of B1 equals 20ms.For reducing the propagation delay time of high level data, RTTI (Reduced TTI reduces Transmission Time Interval) technology has been proposed also.The RTTI overall thought is keep each radio block big or small constant, reduces TTI through utilizing multi-slot.The RTTI radio block is shown in B2 among Fig. 2, and RTTI radio block B2 is on 2 continuous T DMA frames, and every frame takies 2 time slots, and the TTI of B2 equals 10ms.

The inventor finds in realizing process of the present invention, and in the prior art, the terminal is to measurement, the correlation computations of channel quality and report all and be basis, carry out based on the BTTI radio block with a time slot, whenever does once filtration at a distance from 20ms.This scheme is to based on measurement, the correlation computations of the channel quality under the RTTI radio block configuration and report then and can't support.

$\mathrm{MEAN}\_{\mathrm{BEP}}_{\mathrm{Block},b}=\frac{1}{4}\underset{i=1}{\overset{4}{\mathrm{\&Sigma;}}}{\mathrm{BEP}}_{\mathrm{Burst\; i}}$ (formula 5)

${\mathrm{CV}\_\mathrm{BEP}}_{\mathrm{Block},b}=\frac{\sqrt{\frac{1}{3}\underset{k=1}{\overset{4}{\mathrm{\&Sigma;}}}{({\mathrm{BEP}}_{\mathrm{Burst\; k}}-\frac{1}{4}\underset{i=1}{\overset{4}{\mathrm{\&Sigma;}}}{\mathrm{BEP}}_{\mathrm{Burst\; i}})}^2}}{\frac{1}{4}\underset{i=1}{\overset{4}{\mathrm{\&Sigma;}}}{\mathrm{BEP}}_{\mathrm{Burst\; i}}}$ (formula 6)

In this embodiment, what the measurement of RTTI channel quality was adopted is the 10ms filtration in (i.e. RTTI radio block cycle), and the value of forgetting factor is applicable to the 10ms filtration.Calculate RTTI radio block channel measured value (being called for short the radio block measured value); Said RTTI radio block measured value can comprise the bit error rate variance of RTTI radio block average BER and RTTI radio block, and said RTTI radio block measured value calculates according to forming measured value this radio block, that be distributed in four bursts on two time slots.The time slot that calculates RTTI according to said RTTI radio block measured value is to measured value; Then, measured value is calculated the overall channel quality measurement parameters on all assigned channels according to said time slot, for example, overall channel average BER on all assigned channels and overall channel bit error rate variance.

At first, calculate the bit error rate variance of RTTI radio block average BER and RTTI radio block.

Need to prove that among above-mentioned each embodiment, the measured value of the single time slot of measured value that the RTTI time slot is right and BTTI and overall channel quality measurement parameters all are to be directed against the specified modulation type.

Still be embodiment two for the foregoing description one no matter, the RTTI quality measurement parameters is reported network side can have following two kinds to report mode:

(1) do not change existing single time slot measured value report field, utilize the measured value of single time slot measured value report field report based on the RTTI radio block of two time slots (promptly a time slot to).

For example; The terminal in RTTI configuration down based on time slot 0 and measured value GMSK (the Gaussian-Filtered Minimum Shift Keying of time slot 1 this time slot to obtaining; Gaussian Minimum Shift-frequency Keying) the MEAN_BEP value under the modulation system; Both can give tacit consent in the report of time slot 0 corresponding field, also can give tacit consent in the report of time slot 1 corresponding field, as follows:

< GMSK_MEAN_BEP_TN0:bit (4) >; Under GMSK modulation mode, based on the average BEP value that obtains through the RTTI radio block on time slot 0 and the time slot 1.

Can in EGPRS Timeslot Link Quality Measurements IE or EGPRS Timeslot Link Quality Measurements Type 2IE, clearly indicate: during the RTTI configuration; Should in GMSK_MEAN_BEP_TNx or 8PSK_MEAN_BEP_TNx or MODULATION_1_MEAN_BEP_TNx or MODULATION_2_MEAN_BEP_TNx, report the average BER of measuring based on every time slot; Wherein TNx is the time slot of the low timeslot number of each report time slot centering, promptly in single time slot measured value report field of the specified modulation mode of correspondence, reports said RTTI quality measurement parameters.

(2) increase new time slot and report field, utilize under new certain modulation system of field report measured value based on the RTTI radio block of two time slots (promptly a time slot to) to measured value.Because of 8 time slots being arranged on a carrier wave, 4 configurations that time slot is right are promptly arranged, at most so newer field is that optional 4 time slots are to measured value.

For example; The terminal in RTTI configuration down based on time slot 0 and time slot 1 this first time slot to the MEAN_BEP value under the measured value GMSK modulation mode that obtains; Then do not need the corresponding field of original single time slot measured value, as long as in the time slot field report corresponding to measured value, as follows:

{0|1{0<GMSK_MEAN_BEP_PAIR1：bit(4)>

|1<8PSK_MEAN_BEP_PAIR1：bit(4)>}}

{0|1{0<GMSK_MEAN_BEP_PAIR2：bit(4)>

|1<8PSK_MEAN_BEP_PAIR2：bit(4)>}}

{0|1{0<GMSK_MEAN_BEP_PAIR3：bit(4)>

|1<8PSK_MEAN_BEP_PAIR3：bit(4)>}}

{0|1{0<GMSK_MEAN_BEP_PAIR4：bit(4)>

|1<8PSK_MEAN_BEP_PAIR4：bit(4)>}}

Can in EGPRS Timeslot Link Quality Measurements IE or EGPRS Timeslot Link Quality Measurements Type 2IE, clearly indicate: during the RTTI configuration; Should in GMSK_MEAN_BEP_PAIRx or 8PSK_MEAN_BEP_PAIRx or MODULATION_1_MEAN_BEP_PAIRx or MODULATION_2_MEAN_BEP_PAIRx, report the average BER of measuring based on every time slot; Wherein PAIRx is right corresponding to each report time slot, promptly reports said RTTI quality measurement parameters at the time slot of the specified modulation mode of correspondence in to measured value report field.Equally, can discern the RTTI configuration indication of measurement pattern down, following two kinds of methods can be arranged in order to make the terminal:

(1) assigning or reconfiguration message (for example grouping downlink assignment messages, many TBF (Temporary Block Flow; Temporary Block Flow) downstream assigned message, or the time slot reconfiguration message of dividing into groups) or many TBF time slot reconfiguration message or grouping CS (Circuit Switch; Circuit switching) discharges Indication message or PS (Packet Switch; Packet switching) switches wireless resource information field, PS switching Radio Resource 2 information fields; Or DTM (Dual Transfer Mode, double-transmission mode, i.e. circuit domain and packet domain transmission and the pattern of depositing) switches PS wireless resource information field, DTM switches in PS Radio Resource 2 information fields; Do not change the field LINK_QUALITY_MEASUREMENT_MODE and/or the EGPRS2_LINK_QUALITY_MEASUREMENT_MODE field of existing indication link quality measurements pattern; Only the respective option is increased implication, dispose when network carries out RTTI to the terminal, the measurement pattern under the RTTI configuration is promptly indicated in corresponding measurement pattern indication.

Comprise the LINK_QUALITY_MEASUREMENT_MODE field in above-mentioned message or the field of network side through sending to the terminal and/or the EGPRS2_LINK_QUALITY_MEASUREMENT_MODE field is come the indication measurement pattern.

Wherein, during LINK_QUALITY_MEASUREMENT_MODE field indication RTTI configuration, the terminal must report the right average BER measurement parameter of each time slot; The LINK_QUALITY_MEASUREMENT_MODE field has been indicated the measurement parameter that is included among EGPRS Timeslot Link Quality Measurements IE or the EGPRS Timeslot Link Quality Measurements Type 2IE.

(2) assigning or reconfiguration message (for example grouping downlink assignment messages, many TBF downstream assigned message, or divide into groups time slot reconfiguration message or many TBF time slot reconfiguration message) or grouping CS Indication message or PS switches the wireless resource information field or PS switches Radio Resource 2 information fields or DTM switches PS wireless resource information field or DTM switches in PS Radio Resource 2 information fields; Keep original field LINK_QUALITY_MEASUREMENT_MODE constant; Increase a field (1bit at least) newly; This field that increases newly is used to indicate the measurement pattern under the different configurations, like BTTI configuration or RTTI configuration.
