Abstract

The present invention relates to a method and device providing specified reliability parameters due to repeatedly transmitting data frames at minimal required signal transmission power. The proposed method is distinctive by estimating, at the transmitting station, the rate of transmission of error-containing data frames depending on signal transmission power and determining the ratio between the initial transmission power and the repeated transmission power that ensures the specified reliabilityparameters at the minimal transmission power that is required for the initial and repeated signal transmission. First, the transmitting station transmits a data frame at the initial transmission power, then receives from the receiving station an error message that was detected during the data frame reception and repeatedly transmits that data frame at the power transmission level that is defined according to the said ratio between the transmission powers that ensures the specified reliability parameters in communication.

Description

The invention relates to communication, in particular, to a method and device for minimizing the total energy required to transmit an information signal with a desired level of reliability.

The use of modulation for parallel access with code compression of channels (CDC) is one of the ways to ensure communication in systems with a large number of users. Other schemes are also used, for example, parallel access with time division or with frequency compression, amplitude modulation schemes, for example, amplitude companding on one sideband, but PDKU has significant advantages compared to them. The use of PDCU in parallel access systems is described in US Patents 4,901,307 and 5,103,459, which are incorporated herein by reference. The PDU systems were standardized by the Telecommunications Association standard TIA/EIA/5-95 ("Mobile and Base Station Compatibility Standard for Broadband Cellular Systems for Two-Way Extended Spectrum Communications"), included in this description by reference.

The PDKU system is a wide spectrum communication system, the advantages of which are well known. The PDKU system, the signal of which is broadband in nature, provides the possibility of frequency diversification, by which the signal energy is distributed over a wide frequency band. Thanks to this, selective frequency fading affects only a small part of the frequency band of the PDKU signal. Spatial or path diversification is achieved by creating multiple signal paths simultaneously in multiple channels to a mobile user or remote station through two or more base stations (BS). In addition, path diversification can be obtained by using a multipath environment with separate reception and broadband processing of signals arriving with different delays. Examples of path diversification can be found in patents

US 5,101,501 and 5,109,390, incorporated by reference.

PADKU systems have been standardized in the USA by the Telecommunications Association standard TIA/EIA/L5-95-8 ("Mobile and Base Station Compatibility Standard for Wideband Cellular Systems for Two-Way Extended Spectrum Communications"), included in this description by reference.

Initially, the I5-95-B was optimized for the transmission of variable rate voice frames. To provide two-way voice communication, as required by wireless telephony, it is desirable that the system provides a constant minimum data delay. For this, I5-95-8 standard systems are provided with powerful advance error correction protocols (EPC) and vocoders resistant to errors in voice frames. Error control protocols that involve retransmission of frames introduce unacceptable delays in voice transmission and are not covered by I5-95-8.

The optimizations that make the I5-95-B standard ideal for voice applications make it difficult to use for packet data transmission. In many non-voice applications, such as Internet Protocol (IP) transmission, the delay requirements are much less stringent. The most common Internet Management Protocol. Transmission (PRKP) assumes virtually infinite delay to ensure error-free transmission. To increase the reliability of the PRKP, it provides for repeated transmissions of PI packets.

PI packets are usually too large to be placed in one I5-95-B frame. Even after shredding the PI packet into segments sufficient to fit into the I5-95-B frame set, the entire set must be received without error to save that PI packet for the PRCP. The frequency of personnel errors assumed by 15-95-

B, makes the probability of error-free reception of all segments of the PI packet very low.

I5-95-B8 provides for alternative service types for data types that are distinct from linguistic ones. Standard

TIA/EIA/L5-707-A, included in the link, provides for a number of procedures intended for the transmission of data packets in the I5-95-B system.

The Radio Communication Protocol (PRZ (VIR) or PRZ2 (VI Rg)), described in I5-707-A.8 and incorporated by reference, provides for the presence of an error control protocol for frame retransmission procedures at the I5-95-B frame level. PRZ belongs to the class of well-known. error control protocols of the AKO type (MAK-based). PRZ

I5-707 provides in the I5-95-B8 system for the transmission of streams of bytes, and not a sequence of voice frames.

PRZ has several protocol layers. PI packets, for example, are converted into point-to-point (PP) byte streams before forming a byte stream for the PRP protocol layer. Since the RDP layer ignores the protocol and framing of higher protocol layers, the data stream transmitted by the RDP is called an "unsigned byte stream".

The PRZ was developed in accordance with the requirements for the transmission of large packets in the I5-95-B channels. For example, if a PI packet of 500 bytes is to be transmitted in 15-95-V frames of 20 bytes each, then it will consist of 25 complete consecutive 15-95-V frames. These 25 PRL frames must be received without error so that this PI packet can be used by higher protocol layers. If the I5-95-8 channel assumes 195 frame errors, the frequency of errors in PRZ transmission will be 1 - (0.99)25, i.e. 2295, which is a very large value compared to the indicators of most PI networks. PRZ was intended as a channel-level protocol to reduce the error rate in PI transmissions compared to the error rate in . channels of the type "OVaze2 ESegpei".

Recently, the International Telecommunication Union has put forward a requirement to propose methods that ensure high data transmission speed and high quality of voice communication services in wireless channels. The first of the proposals came from the Communication Association under the name "Pe sata2000 ITO-A ATT Sapaidaye b!yYutivviop".

The Communications Association is developing the intermediate standard TIA/EIA/5-2000 (hereinafter - satag2000). The second proposal came from the European Institute of Standards (ET5I) under the name "PE ET5I OMT5 Te!itevigia! Nadio Assez5 (TVA)

ITO-A ATT Sapaidage Z!irtivviop" (hereinafter - M'SOMA). The third proposal ("Te OM/S-136 Sapaidage Z!irtivviop", hereinafter - EOSE) came from TO 8/1 (USA).

PRZ2 was intended for use with I5-95-B. The new PRZ for sata2000 is described in the document

TIA/EIA/L5-707-А-1.10 (VI RZE), included in the link.

The object of the invention is a new method and device for transmitting a signal with a predetermined level of reliability using retransmission of an erroneous frame. The invention includes a transmission method that is as efficient as possible in terms of transmission energy in a system where retransmission of a data frame received with errors is used.

The transmitting station estimates the frame error rate (FRA) as a function of energy. In one embodiment, this station adaptively evaluates the feedback received from the receiving station. In another embodiment, the transmitting station evaluates the state of the transmission channel, for example, attenuation, fading, number of paths, relative speed of the remote station (RB) and the base station (BS). , the transmission rate.The transmitting station then uses a look-up table that contains the model-derived CPP as a function of energy for all possible channel conditions to select the ratio for the given conditions.

Next, the transmission station determines the combination of the energy of the initial transmission and the energy of the retransmission, which will provide the required level of reliability with the minimum expenditure of full energy for the initial and retransmission. The invention provides a closed-form solution for determining the most effective energies of initial and repeated transmissions for an important class of functions describing the relationship between CCP and energy. The invention also includes methods for determining the most effective energies of initial and repeated transmissions for other classes of functions that describe the relationship between CHKP and energy.

The transmitting station transmits a frame with the initial transmission energy. By means of normal feedback, this station receives a message about the occurrence of frame errors at the receiving station, as a result of which it retransmits this frame with an energy determined to minimize the total energy required to transmit this frame with a predetermined level of reliability.

Features, objects and advantages of the invention can be better understood from the following detailed description with reference to the drawings, in which: fig. 1 - conceptual diagram of a typical terrestrial wireless communication system, fig. 2 - diagram of the algorithm of the process of minimization of the total energy of retransmission according to one of the embodiments of the invention and fig. C is a block diagram of a typical embodiment of a transmission station adapted to use the invention.

Fig. 1 illustrates a typical terrestrial wireless communication system that includes BS 102 and BC 104 communicating with each other via a forward link 106 that carries information from BS 102 to BC 104 and a reverse link, which carries information from BS 104 to BOS 102. Information exchange between BS 102 and BS 104 must be carried out with a predetermined level of reliability. In a typical embodiment, the information in the signal 106 of the direct channel is transmitted by frames, and the desired level of reliability corresponds to the desired CHKP when received by the VS 104.

One of the ways to achieve the desired CCP is retransmission. The transmitting station transmits information in frames with the first energy (Ei). The transmitted information is received by the receiving station with the first CHKPI and transmits the value of the first CHKP1 and data identifying the frames received with errors back to the transmitting station. The transmitting station selects a second transmission energy (Eg) and retransmits these false frames. The receiving station receives these frames with the second ChKP2. If the energies EI, Eg are chosen properly, the effective control unit after the second transfer will be equal to the desired one.

There is an infinite number of combinations of EI and EGI that provide the desired CKP. Since communication systems, in particular with PDC, have limitations caused by noise, it is advisable to choose "Ei and E" in such a way as to minimize the total energy of transmission. The total energy (EE) of transmission is equal to the energy of the first transmission plus the transmission energy of those frames that were initially accepted with errors: "E" t Ei 4 KEOE" (1) where En is the energy of the first transmission,

Eg is the energy of retransmission, and KEi) is the transmission control unit with energy Ech.

The condition that the effective control system will be equal to the desired one is as follows:

Tchkp - KEOKE») (2) where Tchkp is the desired CCP, which is equal to the product of CCP during transmission with energy En, i.e. KEi) and CCP during transmission with energy E", i.e. (Eg). So, the problem of choosing En and Eg to minimize the total energy (E) is effective

The CPC after the second transfer will be equal to the desired one, which is reduced to the solution of equation (1) with constraint (2). Any method of solving equation (1) with constraint (2) requires knowledge of the CPP as a function of energy or a measure of energy illustrated by (3):

AkP - KE) (3) where the measure of energy E can be, for example, the ratio of energy per bit to noise (EMMo). This ratio is a function of several variables, including (but not limited to) attenuation, fading, number of paths, and relative speed of the VS and BO.

After determining relation (3), various methods can be used to solve equation (1) with constraint (2). Therefore, an analytical solution can be obtained for an important class of functions. It is clear, however, that the solution of equation (1) with constraint (2) can be found using numerical methods. To obtain an analytical solution, it is convenient to change the scale from linear to logarithmic. First, equation (1) is normalized by introducing an arbitrary constant Es for energy: (E/Eo) - Ex/Eo 4 KEOE»/Eo (4)

Since the CHKP can have a value between 0 and 1, the logarithmic relationship will have the form: x - IP(KE)), x is (-ос,0) (5) в Ех IP(Е/Ео), У is (-со,е so) (6)

Substitution (5) and (6) in (4) and (5) gives: (E/Eo) - Exhr(ui) - Exhr(xi kug) (7) n Point 2 (Xi z Kho) (8)

The dependence of (7) on ho can be eliminated by substitution with (8). The stationary point of total energy according to (7) can be determined by taking the derivative of (7) with respect to xi and equating it to 0:

O(E/Eouahi - Ehr(udui i Ehri(hi i ug(1 -ug)-0. (9) where ut is a derivative of ui along Kh and y" is a derivative of y along kh After obtaining from equation (9) of the stationary point of full energy is calculated and is equal to 0 the second derivative of (7), which gives the minimum of the stationary point of full energy: аг(Ео/Ео)/ахі2 - Ехр(ут) (in уй") and Эхр(хи (10)

уг)Ц1 у уг") - 0 where ух" is the second derivative of уй on Хи and уг" is the second derivative of уз on хи.

In practice, in many cases, the CHKP of the channel is a step function of the energy:

KE) - o(E/Eo)" (11)

Transformation (11) according to (5) and (6) gives: у т бо-хуу 12) where хо - Ип ио and equations (7) and (8) are significantly simplified, since уг-уг--1/у (13 ) in -0 (14)

After substituting (13) and (14) in (7) and (8), the solution of equations (7) and (8) is obtained in closed form: hip Tukp-u! p(u-1 Ku 2) (15) khihIpTchkp-khi (16) ut - Ku zh To Tchko zh uip(u - TKU gu g) (7) ug - y1-(p(Tchk(u-1)2) 3Shung) (18)

Ip((E/Eo))tip - uzi - Ip((y - 2)Mu -1)) (19)

Interpretation (19) shows that retransmission according to the above principles is carried out if the relation holds

К(ЕЖЭ»2) 2 КЕ1--4(Е(Е") (20)

If the ratio (20) is not maintained, it is better to carry out the transfer according to (Е) - КЕ1--КЕХЕ") (21)

This happens at very large values of y.

Although the mathematical justification of the retransmission method for simplification was given for a single transmission, the principles of this method are easily extended to any number M of retransmissions. A person skilled in the art easily modifies equation (1) for the case of many retransmissions:

Equation (2) for many retransmissions takes the form

Fig. 2 contains a block diagram of the load estimation algorithm according to the invention. The procedure begins with operation 202, in which the transmission station evaluates the control unit as a function of energy. In one embodiment, this station adaptively evaluates the feedback information received from the receiving station. In another embodiment, the transmitting station evaluates the state of the transmission channel, for example, attenuation, fading, number of paths, relative speed of the BC and BS, transmission speed. After that, the transmitting station uses a look-up table that contains the CCP obtained on the model as a function of energy for all possible conditions in the channel, and chooses the appropriate ratio for these conditions.

By operation 204, the transmitting station reads the required control unit, after which, by operation 206, it estimates the energy E! initial transmission and energy E"....Em of potential repeated transmissions according to the above principles.

Therefore, the transmitting station can use previously calculated solutions of equations (15-19) in the form of a reference table or, depending on the circumstances, implementing the algorithm for solving equations (22) and (23) by numerical methods.

By operation 208, the transmitting station transmits an information frame with energy E|y, after which it evaluates whether this frame was received without errors (operation 210). If the message from the receiving station is positive, the procedure begins again with operation 202, otherwise, the transmitting station determines (oper. 212) whether another transmission energy Eg2...Em is available. If so, with operation 214, the transmitting station retransmits the information frames that were previously received in error with the next available energy, then transitions back to operation 210. Otherwise, the transmitting station informs the higher-level algorithm of the failed transmission (operation 216) and returns to operation 202.

Fig. C contains a block diagram of a typical embodiment of a transmission station adapted for application of the invention. The information to be transmitted is generated by the data source 302 and sent to the channel element 304, which divides it into separate parts, forms the CCN code and adds tail bits according to system requirements.

In addition, the channel element 304 convolutionally encodes the data, CCN bits, and tail bits, interleaves the encoded data, scrambles the interleaved data with a long pseudo-noise (PSN) sequence, and overlays the scrambled data with a Walsh sequence. The data then enters the amplification stage 306, which, according to the signal from the processor 308, scales the data so that it arrives at the transmitter 310 with the desired energy E" The transmitter 310 expands the scaled data with short sequences of PID and PSO, after which the expanded data is modulated with phase and quadrature-phase sine waves and the modulated signal is filtered, transformed with Further, the signal is transmitted by the antenna 312 in the forward channel 106, if the transmitting station is BS, or in the reverse channel 108, if the transmitting station is all.

The feedback signal from the receiving station is received by the antenna 314 and sent to the receiver 316, which filters, amplifies, reduces the frequency of the signal, quadrature demodulates it and digitizes it. The digitized data is fed to the demodulator 318, which decompresses this data with short sequences PSH;: and PSHo and decompresses them with a Walsh sequence. Convoluted data from different correlators of the C3xx demodulator are combined and descrambling with a long PS sequence. The data is then sent to the decoder 320, which performs the reverse of the encoding performed by the channel element 304. The decoded data is sent to the consumer 322 and to the processor 308.

The purpose of processor 308 is to perform operations 202, 204, and 206. It also controls amplification stage 306, which scales the data for transmission with the energy determined by operation 206 and thus performs operation 208. The functions implemented by operation 210 are performed by processor 308 , based on the information received from the decoder 320 about the presence or absence of errors when the receiving station receives the transmitted data. In addition, the processor 308 performs a decision function (operation 212) and, depending on the decision, informs about the failed transmission (operation 216) or instructs the data source 302, the channel element 304 and the Xxx amplification stage to retransmit the information frames that were taken by 3 errors, with the next available energy determined by operation 214.

The above description of preferred embodiments will allow any person skilled in the art to use the invention by making appropriate modifications and changes in accordance with the concepts and principles of the invention. The scope of the invention is not limited to the given embodiments and is determined by the given new principles and features. 105. And the seam mon ІІ
