Abstract

A novel method and apparatus for achieving optimum capacity and stability in IS-95-B based medium data rate systems. Each user served by a base station is allocated a constant portion of available transmission power. A data are transmitted to each user at this allocated transmission power and a data rate is varied in accordance with the user's channel condition. This strategy removes the variation in transmission power when a user switches between a maximum and minimum rate, thus increasing stability and capacity of the system. The capacity is further increased by allocating a constant portion of a total available transmission power of a base station is allocated to a power for data transmission power for data transmission on a fundamental forward channel and a power for transmission on supplemental forward channels. Each user is allocated one fundamental channel. Rate of transmission of data to a user is varied by allocating supplemental forward channels based on the RF conditions of a communication link and the required data rate of each of the user. The allocation is controlled by a scheduling method. In another aspect of the invention the base station, transmitting on a fixed power is allowed to gradually adjust this fixed power to allow changes in a long term data throughput.

545001 V. Description of Invention (2) Meeting. Due to the inherent nature of wideband signals, the coded multi-directional approach provides a type of frequency diversity by spreading the signal energy over a wide frequency band. Therefore, frequency selective fading affects only a small part of the bandwidth of the coded multidirectional proximity signal. By linking more than two base stations to mobile users or remote stations at the same time, multiple signal paths are provided in order to obtain space or path diversity. Furthermore, the multipath environment can be utilized through spread spectrum processing to obtain path diversity; which allows signals arriving at different propagation delays to be received and processed separately. An example of path diversity is described in US Patent No. 5,101,501, named π to provide communication in a coded multidirectional proximity cell phone system, a method and system for soft handover π, and patents American name ...

It is called ARQ communication protocol based on NAK, and it is quite famous in the art. 1s * · 707 R L P is transmitted through a byte stream through an I S-9 5-B communication system, instead of a series of voice frames. Several communication layers usually exist above the R L P layer. For example, IP data is typically converted into a point-to-point protocol (P P P) byte stream before it is considered to be a byte stream to the R L P protocol layer. Because the r L P layer ignores the frames of this communication protocol and higher protocol layers, the data stream transmitted by r L p is referred to as the π uncharacterized byte stream π. R L P was originally designed to meet the need to reliably transfer large amounts of datagrams through the I $ — 9 $ channel with electrical wires.

The International Telecommunications Association recently requested a submission of the proposed method, which can provide high-speed data and high-quality speech services over wireless communication channels. The "Nomenclature of π-Code Multi-Directional Proximity 2000 ITU-R RTT Alternate Submissions" of these proposals discussed by the Telecommunications Industry Association is currently being developed. The Telecommunications Industry Association is currently developing a multi-code Proximity Proposal for 2000-00 This is the interim standard Τ IA / Ε IA / IS-2 0 0 0, hereafter referred to as coded multi-directional proximity 2 0 0.

The I S-9 5-A speech system depends on the large number of unrelated users' per cell per cell and Markov speech statistics for proper performance of radio frequency (RF) capacity and RF stability. A large number of users who are not relevant for proper performance lead to forward link RF transmission power allocation, which is a predictable statistic and has 10 g-η r m a 1 configuration. Without this forward link rf power predictability, the forward link power control and action assistance handover may become unstable.

O: \ 71 \ 71165.ptd Page 9 545001 V. Description of the Invention (5) Unfortunately, the packet data flow cannot be performed well. The data stream often bursts, resulting in a long time transmission at the maximum rate, and a long time transmission at the maximum rate follows a long time transmission at the minimum rate. With the advent of IS-95-B media data rates, these effects have become more pronounced. Multiple links for medium rate users are related. Unlike uncorrelated voice links, the data link switches between maximum and minimum rates, as well as power control. This makes this forward-link RF transmission power allocation remarkably abnormal and non- 10 g-η r m a 1, and thus potentially unstable. Therefore, when using MDR, it is necessary to raise the issue of network stability and capacity without changing the "S-95-B air interface standard." I. Summary of the Invention The present invention is directed to a novel method and device to achieve the optimal capacity and stability of a media data rate system based on IS-99.5-B. According to the present invention, a fixed portion of the base station's total available transmission power is allocated to each user. The transmission power allocated on this basic forward channel transmits data to each user and changes the data rate according to the user channel conditions. According to another aspect of the present invention, a fixed portion of the total transmission available power of the base station is divided into the data transmission power of the basic forward channel and the transmission power of the auxiliary forward channel. Each user is assigned a basic channel. The data transmission rate for a user varies with the configured auxiliary forward channel, and it depends on the RF status of the communication link and the data rate required by each user. Another aspect of the present invention allows a base station transmitting at a fixed power to gradually

Schematic description of the diagram is briefly shown in the comprehensive drawings and the following detailed description. The features, objects, and advantages of the present invention will be made more transparent. Similar reference characteristics in the drawing correspond to the identification output rate, where: Figure 1 is a bar chart showing the power allocated to the user. Figure 2 is a bar chart illustrating the power allocated to the base station. FIG. 3 shows an exemplary embodiment of a terrestrial wireless communication system. Figure 4 shows an example of a base station based on a specific example. Figure 5 is a top-level diagram illustrating the process of completing stability and capacity control according to a specific example. Figures 5 A-D show a sample specific example of a flowchart according to a specific example. Detailed description of a preferred specific example Figure 1 illustrates a specific example of the present invention, which is used for data transmission at a fixed power level per user and the available data rate according to the user RF link status. This is a viable option because unlike voice services, which require minimum bandwidth and maximum latency, packet data users have unconvincing GoS requirements. According to a specific example, in addition to assuming one or more forward-coding channels, it is also assumed that the packet data page is a fixed full power. Figure 1a shows a total power configured for PTMDR transmission at media data rate. This power satisfies Equation 1:

O: \ 71 \ 71165.ptd Page 11 545001 V. Description of the invention (7) where Ptih is a total power allocated to user i 'and N is the number of users. Figure lb shows the total power PTMDR allocation available between the basic forward channel power PFU and the M auxiliary forward channel Psu. The allocation is performed in a mode that satisfies the following equations: (2) PTUi = PFUi + YjPSUi ^ Its direction is transmitted by the channel user to assist the forward auxiliary material transmission, the demand rate, PTUl in the forward direction is the total number of user i Power and Mi are the predecessors to users i. The user on the basic forward channel starts this call with a data rate low enough to ensure that the power control change of the basic forward channel does not exceed the allocated power PFU. Then, according to the basic channel power PFU, the auxiliary forward rate hierarchy Psu is placed. Equation (2) is then used to determine the maximum number of channels that can be used. Because the forward channel power control only affects the basic channel, use equation (2) and the maximum number of auxiliary channels to adjust the power level Psu of the forward channel. If there is no data on the auxiliary forward channel (because there is not enough power, or all the information on the basic forward channel and the channel can be used); when there is sufficient power to ensure that equation (2) is satisfied, the empty auxiliary forward channel can be transmitted. If the required transmission data rate power exceeds the total user power Pτυ, a very low data rate is transmitted to maintain the required power below the total power. First achieve low data rates by using fewer auxiliary channels, then by using less than full power

O: \ 71 \ 71165.ptd Page 12 545001 V. Description of the invention (8) Basic forward channel. The number of radio link protocol (R L P) sequences allows this mobile station to determine whether the auxiliary forward channel demagnetization is the result of packet demagnetization or 3 transmission packets. Transmission at " fixed user power π will reduce the base station's transmission power variation, which is caused by power control and data activities. However, because when no data is transmitted, this method will fail. The difference between the minimum and maximum user data rates is greater and the potential for failure is greater. Therefore, in another embodiment of the present invention, the base station allows time sharing of forward link media data rate power PTMDR. The base station assigns a unique basic forward channel to each household with medium-rate packet data. Second, the base station assigns a number of configurable auxiliary forward 'channels from zero to the maximum to each medium-rate packet data user. In ~ two specific examples, for each user, the maximum number of auxiliary forward channels that can be configured is seven. These auxiliary forward channels can be assigned to multiple users simultaneously. Through the long code of a specific user, the base station covers every frame of the auxiliary forward channel to count the use of these auxiliary forward channels during the day. Therefore, all users who do not use this particular long code will not be able to decode auxiliary channel frames intended for other users. Figure 2 illustrates the power allocation in this case. Figure 2a shows the total power allocated for media data rate PTMDR transmissions. This power satisfies Equation 3:, 'N N Mj PTMDR ^ ZjPTUi + Σ YuPSUiJ (3)'. = 1 / = 1 / = 1 y = l where PTUi is the total power allocated to user i and N is the number of users. Figure 2b shows the media profile between these auxiliary and basic forward channels

O: \ 71 \ 71165.ptd Page 13 545001 V. Description of the invention (9) The total power allocation of the rate Ptmdr transmission. Since N users are used, the distribution of the basic forward channel ruthenium-power PTF is included. For each user, it can be used to sum up the total forward channel power PFU, so: The right column of the bar graph of 2b illustrates this. The left column of the bar graph in Figure 2b illustrates the power PTs allocated to these auxiliary forward channels. It should be noted that according to the principle of adjusting the data rate, no auxiliary power PTs are allocated for the auxiliary forward channel CHi between N users. These M auxiliary forward channels CEp are available to all users who need the basis. Therefore, when the data rate demand for a particular user increases, an additional channel is allocated to the user from the power PTs of the auxiliary forward channel. However, the user cannot use more auxiliary forward channels than the user is assigned. Conversely, when the data rate requirement for a particular user decreases, the user directly grants the auxiliary forward channel to another user. The rate of allocation and deallocation must be chosen so as not to interfere with power control. The power distribution among these users must satisfy equation (5):

Ptmdr = Ptf + Pts (5) The use of π fixed user power π and π shared auxiliary forward channel π for transmission can reduce the transmission power variation of the base station due to the power control of each user and the data activity of each user. However, long-term changes in transmission power due to changes in data activities and changes in data demand will not reduce transmission power changes in short periods. According to another specific example of the present invention,

O: \ 71 \ 71165.ptd Page 14 545001 V. Description of the invention (ίο) The base station transmitting at a fixed π power level uploads to the channel before being used ^ It is equal to the power required for data transmission and the n fixed π power If the power difference between the layers is ^^, the base station will reduce the change in transmission power caused by the change in data activity. Because users can have different frame displacements, each power control group must adjust the extra power transmission. The explanation of power control can refer to the above-mentioned IS-9 5 standard. Adjusting the “π fixed” power level can mitigate changes caused by data requirements. Therefore, when the data demand decreases, the base station reduces the amount of π fixed π power allocated to the data service. In a specific example, The change gradually prevents interference with the power control method. In a specific example of the present invention, the π fixed π transmission-power level is controlled by an external power control loop. This external power control loop adjusts the fixed transmission power level so that This fixed level will not fill up too often. The additional limit of the precise amount of π fixed `` power adjustment allows new users to enter the base station. Figure 3 shows a model concrete example of a terrestrial wireless communication system. BS) 302 and Remote Station (RS) 304 indicate that they communicate on the forward link 306 to carry information from the base station 302 to the remote station 304 and communicate on the reverse link 308 to communicate from the remote Stations 304 to 302 carry information.

The data from the memory 404 is provided to the demultiplexer 6 =, which multiplexes the data f according to the signal 408 provided by the control circuit 410. The demultiplexing data is provided to the channel elements 4 1 2 a to 4 1 2 h, which divides the data, CRC encodes the data, and inserts the last bit of the code as required by the system. Then the channel elements 4 12a to 41 2h perform convolutional coding on the data, CRC parity bit, and the last bit of the code, interleave this coded data, use user long false noise (PN) sequence to disturb the interleaved data, and use Walsh sequence Overwrite the disturbing data. At this time, the channel elements 4 1 2 a to 4 1 2h respectively provide the coverage data to the expanders 4 14ι to 41 4h, which can use short in-phase false noise (PNPr and orthogonal false noise (PNQ) sequences to expand the Data. For more details, please refer to the above-mentioned IS-9 5 standard. Filter the expanded data in the filters 4 1 6 a to 4 1 6 h, and provide the filtered data to the gain stages 4 18a to 41 8h. It responds to signals 42 0 a to 4 2 0 h from the control circuit 41 0 to scale the data.

Come up-convert the data. Provide the up-converter U tiger to gain stage 426 for scaling. This scaled signal is filtered and amplified in block 430. If the transmitting station is a base station, then the signal is transmitted on the forward channel 306; if the Transfer station is End site, is transmitted through an antenna 432 on the reverse path transmission signal 308 via an antenna 434, receives from the receiving station (not shown) of

The receiver 4 3 6 filters, puts ^ :, down-converts, forwards demodulation, and digitizes the received signal. This digitized signal is provided to the demodulator 4 38, which can unwind the data using a short * PNQ sequence, and uncover the anti-expanded data using a user long PN sequence. De-interference (or demodulation) data is provided to the decoder 44 0, which performs the inverse of the encoding by the channel element 4 1 2. Provide the decoded data to the data slot 4 4 2 and the control circuit 4 100. Figure 5 is a flowchart illustrating a process of completing the stability and capacity control according to a specific example. The process begins-at step 5 0, where the transfer station is initialized in a ready-to-ready state-to provide user services. The initialization process may include an initial allocation of the total transmit power of the transmitting station. According to a specific example of the present invention, the total transmission power is allocated between the voice service and the data service on a long-term basis. In another specific example, the allocation of total transmission power is dynamically changed between voice services and data services. To explain the power allocation, it is assumed that the transmitting station supports several voice paging and several data users. In step 502, the transmitting station receives a request for a data service and sends it to step 504. Step 5 0 4 shows an example of the transmission planning method. Step 5 0 4 2 Decide whether the request should be approved. If the request is not approved, the request needs to be sent for further transmission planning processing in step 5044. Send the request for re-planning to step 506. If the request is approved at step 50 42, processing continues at step 50 6.

In a specific example of variable power allocation, Figure 5a describes the function of step 508. In step 5 0 0 2, it is asked whether to re-allocate the power from the voice service to the data service. If the response is affirmative, redistribution is performed at step 5 0804, and the flow continues at step 5 06 of FIG. Referring to Fig. 5a, if the response is negative, it is further inquired at step 5 0806 whether the maximum transmission power of the base station has been reached. If the response is affirmative, there is no available power, and the request is sent for processing in step 50 4 0 4. • If the answer is negative, the base station will allocate ^ part of the total transmission power to the data service at step 5 0 8 0, and flow continues at step 5 6 in FIG. 5. In a specific example of permanent power allocation, Figure 5b describes the function of step 508. Because the power sharing of the voice service allocation is not allowed, it is asked at step 5108 whether the maximum transmission power of the base station has been reached. If the response is affirmative, there is no available power, and the request processing is sent at step 5044 of FIG. Referring to Fig. 5b, if the response is negative, the base station allocates part of the total transmission power to the data service at step 5 0 8 12 and the flow continues at step 5 6 of Fig. 5. When the response with sufficient power is determined in step 504, it proceeds to step 5 10 of the flowchart.
