1322632 IX. INSTRUCTIONS OF THE INVENTION: TECHNICAL FIELD OF THE INVENTION The present invention relates generally to telecommunications, and more particularly to methods, apparatus, and articles of manufacture for broadcast and multicast from a cellular radio network . [Prior Art] It is desirable for a modern communication system to provide reliable data transmission for a variety of applications including voice and data applications. In the case of point-to-multipoint communication, communication systems are known to be based on Frequency Division Multiple Access (FDMA), Time Division Multiple Access (TDMA), Code Division Multiple Access (CDMA), and possibly other multiple access communications. mechanism. A CDMA system can be designed to support one or more CDMA standards, such as (1) "TIA/EIA-95 Mobile Station-Base Station Compatibility Standard for Dual-Mode Wideband Spread Spectrum Cellular System" (this standard and its enhanced revisions) Versions A and B can be referred to as "IS-95 standard"); (2) "TIA/EIA-98-C Recommended Minimum

Standard for Dual-Mode Wideband Spread Spectrum Cellular Mobile Statk>n,,,, is also referred to as "IS-98 standard"; (3) initiated by an association for the "3rd Generation Partnership Project" (3GPP) A standard embodied in a set of documents, including those referred to as 3G TS 25.211, 3G TS 25.212, 3G TS 25.213, and 3G TS 25.214 ("W-CDMA standard"); (4) by a A standard sponsored by the association of "3rd Generation Partnership Project 2" (3GPP2) and embodied in a set of documents, including "C.S0002-A Physical Layer 112048.doc \

Standard for cdma2000 Spread Spectrum Systems" ' "C.S0005-A Upper Layer (Layer 3) Signaling Standard for cdma2000 Spread Spectrum Systems" (collectively "cdma2000 standard") ; (5) lxEV-DO Standard "TIA/ EIA/IS-856 cdma2000 High Rate Packet Data Air Interface Specification"; and (6) some other standards. The standards listed above are incorporated herein by reference in their entirety (including attachments, appendices, and other appendages). Manufacturers continue to add performance enhancement features to wireless user equipment (UE) devices used in cellular radio networks such as cellular phones. For example, many UEs include a display with sufficient resolution to provide video display. Users have become more interested in being able to receive TV broadcasts due to the enhanced capabilities of their UEs. There is demand and there is a supply that follows it. Clearly, the cellular infrastructure delivered to the UE already exists. As a result, operators of cellular networks will benefit from providing broadcast or multicast services to their subscribers. In addition to the more well-known services provided by the Internet, live TV, movies, sports clips, and live interviews can all be broadcast from the cellular radio or multicast. This can be similar to providing a cable or satellite channel directly to the UE. The Multimedia Broadcast Multicast Service (MBMS) is a broadcast service that is available via existing Global System for Mobile Communications (GSM) and Universal Mobile Telecommunications System (UMTS) cellular networks. MBMS and its enhanced version E-MBMS are being standardized in each group of 3GPP (Third Generation Partnership Project). Downlink (DL) capacity is an important performance feature of a cellular system. The increased downlink capacity can be used, for example, to enable more broadcast/multicast traffic to be used by the subscriber and can be used to improve the quality of the broadcast transmission. For a fixed frequency range that can be used for cellular system transmission, capacity depends on spectral efficiency. Assuming limited availability of electromagnetic spectrum, it is necessary to increase the spectral efficiency of the cellular system (including the spectral efficiency of broadcast and multicast, avoiding the costs associated with infrastructure updates, and the need to increase the spectral efficiency of the existing base (10) without or There are limited variations. Many base transceiver stations (BTS) of existing cellular radio network locations (nodes) have a single transmit antenna for single-frequency network operation: Therefore: technically it is necessary to increase the cellular type Network round broadcast and multi-cast transmission frequency per efficiency without the need to install multiple antennas on existing cellular locations.

Given the same transmit power budget, Multiple Input Multiple Output (MIM〇) technology can increase the spectral efficiency of wireless communications. MIM〇 uses a spatial diversity transmit antenna at a transmitting entity and multiple receivers at a receiver. Space diversity antenna. Consider a basic example with two transmit antennas Ντ ι & Ντ2 & two receive antennas NR, 1 & NR, 2, there are four physical transmission channels: ^^, CH between CH1, 1 and 11, 1丨' Ντ, 丨 and nr, 2 between CHl 2, nt, 2 and NR, i between CH2, 1 ' and Nt, #Nr, 2 between CH2, 2. (Representation CHi,j corresponds to a channel between a transmit antenna Nu and a receive antenna NR,y.) Each of these channels is via channel conditions such as delay, interference, noise, multipath/attenuation, Dispersion and distortion. Because of the spatial diversity of the receive and transmit antennas, the composite effect of these conditions is usually different for each of these channels. In this document, 'corresponding to a channel CHi, the channel coefficient of j is called hi,』. A channel matrix ugly for all channels between Ντ transmit and Nr receive antennas is then defined as follows: 112048.doc IS12W1 Λι,ι hi,2 • hi. hi·, hl.2 . • h2. H = • • • • • hm.i Hnr.i • · * Hnr, which can be used to estimate the available channel matrix ugly. It should be noted that each coefficient must not be a simple multiplier coefficient, but encompasses all factors that affect the associated channel. Consider a simple condition with two transmit antennas and two receive antennas (meaning 'heart = 2 and Lu NR = 2), and - the first transmit stream π 〆 at a given frequency F) is from NT > 1 The transmission and the transmission of a second stream are transmitted from the port. On the receiver side, a first received stream is received at nr > 1, and a second received stream and heart is received at Nr, 2.

This will be explained in more detail in the literature, including, for example, the serial number 11/〇〇9, 2〇〇, file number 2005/0157805 titled "Data Transmission With Spatial Spreading in a Mimo The United States patent application for the common transfer of Communication System.".

In the above discussion, it is assumed that each transport stream is broadcast from a single antenna. It is also possible to broadcast one stream from multiple transmit antennas. In the latter case, we can regard each channel coefficient hu as a coefficient from a transmission channel that transmits a stream of loops 5 to a receiving antenna (or a fixed antenna group of a receiving antenna group 1). The analysis process is similar to the analysis of the condition of one of the transmit antennas. The open loop technique can be used as an additional option to increase the spectral efficiency of the broadcast and multicast of the cellular SFN. Transmitting antennas, so one method of transmitting multiples is to transmit multiple antennas from the same location or sector ("cell·') Streaming. In a SFN deployment for broadcast, the received signal-to-noise ratio (SNR) at the UE can be very high; for a macro-cell link budget with a distance of 2800 meters, 95% For users, the SNR is typically higher than 14 dB. Some system simulations show that for a 1 X 1 deployment, the E-MBMS has an SFN spectral efficiency of 1.2 bps/Hz for 95% coverage. The transmit and receive antennas, high SNR makes it possible to use an open (no feedback) 之一 as an additional option for E-MBMS.

In each orthogonal frequency division multiplex symbol (subcarrier), each stream can be transmitted from the radio network 1〇5 to the UE 14〇 on a separate antenna; The mapping of the stream ID to the transmit-antenna ID changes over time 'so that the scale \ SNR of each stream is approximately the same. Since there is usually no loss, we assume a relatively simple situation of this situation, where: S = NT. In order to be able to obtain an accurate channel estimate for each Tx-Rx antenna pair, the pilot subcarriers are not reused on the τχ antenna. This is different from the data subcarrier index, 112048.doc •24· 1322632 These indexes are reused on all Τχ antennas. Therefore, the following formula holds:

Pi 〇 Pj = φ v / ^ y, where the set of pilot subcarrier indices on the 6 e antenna i. The Rx symbol for a given OFDM symbol can be written as follows: N-1 Nj-1 YM = I ZHijM-XjM + v[k] i=0 j=0 =Z'CjM.Xjtk] + v[k], j =〇 where X』[k]=pre-IFFTTx modulation symbol on subcarrier k on antenna j,

The composite SFN channel frequency response for each Tx antenna can be estimated using, for example, a minimum mean square error (MMSE) or a low complexity zero-forced Robust MMSE solution. After channel estimation, an MMSE filter can be used to achieve cross-talk separation and inter-stream interference rejection. This can be written by calling the orthogonal projection lemma as follows: Y[k] = CJ^-XJk] + XCjW-X^k] + V[k] i=〇j vs f[k] = + j= 0 where A[k] = E{V[k].VH[k]}· After being separated by the receiver stream, each stream can be decoded separately, and then 112048.doc -25- 1322632 from all other strings The stream continuously eliminates the iterable elimination step until all streams are decoded. The complexity of continuous interference cancellation (SIC) depends on the number of streams. On the receiving side, a receiver (such as UE 140) uses a first receiving antenna to receive a first signal and a second receiving antenna to receive a second signal. The first signal includes a first data stream transmitted from a first transmit antenna or a first transmitter antenna group via a first physical channel and a first transmit antenna via a second physical channel Or a first data stream transmitted by a second transmit antenna group. Similarly, the second signal includes the first data stream transmitted via a third entity channel and the second data stream transmitted via a fourth physical channel. Estimating the four channels β with the information provided by the receiver using, for example, a pilot channel at the receiver or the wireless network. The first and second data streams can then be separated by the receiver to obtain a first A separate data stream and a second separate data stream. After separation, the receiver attempts to decode the first data in the first data stream and the second data in the second data stream. If the first attempt to decode the data is unsuccessful, the receiver attempts to decode again after partial decoding cancellation interference based on the first attempt. The first and second data streams can be multicast or broadcast on the shared channel. ~ Because Open Path # and Multicast transmission are usually for worst-case receivers, continuous interference cancellation can be omitted if not all target UEs perform this step. To date, this discussion describes one embodiment of Figure 1, one of which The SF frequency 曰 efficiency of an OFDM system uses multiple antennas in a cell (ie, the price of 2). The operation of the embodiment is not limited to the use of 112048.doc • 26- OFDM 'and other methods of using ΜΙΜΟ can be used." As mentioned in the prior art section of this document, many cells (sectors) have a single transmit antenna. Adding a transmit antenna to a location involves additional costs that the operator should avoid. Therefore, in other embodiments, we have not assumed that the transmit diversity is from a single cell. The truth is, we assume: S = min(N*NT,NR)>l, price=1 (meaning one transmit antenna per cell). In other words, we assign transmit antennas as an array and transmit different streams of data from different groups, and one transmit antenna group transmits one stream. Here, 'because each stream can be transmitted from a subset of the network cells', the SNR can be lower than the strict snf operation of all cells transmitting the same stream. Nevertheless, the SNR is still high enough to take advantage of spatial multiplex gain. This is especially true when the ratio of the groups/streams is small and therefore the number of transmit antennas in each group is relatively large, providing a good range covering the entire geographic area of interest. In this configuration, there is a problem for their UEs located within a cell because these UEs have a high carrier interference (C/Ι) ratio based on stronger signals from only one cell. These UEs do not benefit from space multiplex, but may rely on other multiplex technologies such as time multiplex (TDM) and frequency multiplex techniques. Figure 4 illustrates a single frequency radio network 4〇5 that is broadcast or multicast to UEs 440 A and 440B using TDM and M1M. The radio network 405 includes a radio network path controller 410 and cell/BTSs 420, 424, 428 and 432. (In this embodiment, each cell is connected to a BTS, but this is not always the case.) The BTSs have respective transmit antennas 421, 425, 429, and 433. Wireless 112048.doc -27-1322632 The structure of the electrical network controller 410 can be similar or identical to the structure of the radio network controller 11. The structure of each UE 440 Α / 。 may also be the same or similar to the structure of the UE 140. However, here the radio network 405 and UE 440 are configured to communicate in accordance with the methods described below with respect to this embodiment. In this embodiment $=^' uses a generic PRAP or code reuse BLAST (CR-BLAST) mechanism and self-sufficient cell pass at any given time.

Nr sends a stream. Therefore, each of the streams corresponds to the associated cell

One of the groups transmits a group of antennas. The mapping of the stream to the transmit antenna group changes over time.

In this case, multiple streams are multiplexed in a time division multiplex on a single transmit antenna per cell. In the case of, for example, two streams, one half of each slot can be dedicated to one stream, and the other half of the symbols are dedicated to the second stream. For example, in a first time period (τι), a first symbol stream is transmitted from a first transmit antenna group including transmit antennas 425 and 433 of BTSs 424 and 432, and includes a _42 自(d) The second transmit antenna group of the transmit antennas 421 and 429 transmits the 42-symbol stream. In a subsequent time period (T2), the first stream ' is transmitted from the second transfer group while the second stream is sent from the -th transfer (four). The loop is then repeated by repeatedly switching the stream-antenna group mapping. In the description of FIG. 5, a time period TW_N is set up, in which the radio network transmits the stream from the group and transmits the second stream from the second group; The first stream is transmitted from the second group and the second stream is transmitted from the first group during a time period called Τ2. The peers, such as UE 440, are far enough away from each of the transmitting antennas. I248.doc • 28· 2632 uses the space multiplex gain generated by ΜΙΜΟ to benefit. In other words, UE 44 〇 a receives two symbol streams. At the same time, UEs within the cell, such as UE 440B, benefit from time multiplexing and high C/Ι. In other words, the UE 440B receives only the streams, and has a relatively high C/Ι ratio and associated high SNR, especially when the UE 44〇B is close to a transmit antenna.

After stream separation, each stream can be independently decoded and then continuously eliminated from all other streams. The steps can be iteratively eliminated until all streams are decoded. The complexity of continuous interference cancellation (SIC) depends on the number of streams. The receiver of this embodiment may receive a first signal by using a first receiving antenna in one or more first time periods and receive a second signal H signal by using a second receiving antenna, including (1) one via _[physical channel a first data stream transmitted from a first transmit antenna or a first transmit antenna group, and (7) a second data stream transmitted from the second transmit antenna or the second transmit antenna group via the second physical channel . Similarly, the second signal includes: the first data stream transmitted by the third physical channel and the second data stream communicated via a fourth physical channel. The first data stream carries the first time period of the first time period and the second data stream carries the second data of the (first) time period. ★: The four channels are estimated using the pilot channel at the receiver. The second data stream can then be separated by the receiver to obtain a first separated data stream and a first stream of the first stream. After the separation, the receiver maps the first data in the first data and the second data stream in the second data stream. ^ 第 Right decoding ternary _ ^ ^ If the type 5 is unsuccessful, the receiver can attempt to re-interpret based on the partial decoding obtained in the first attempt after eliminating the U2048.doc -29-1322632 interference. The receiver may also attempt to receive the signal decoding data from the subsequent time period. Therefore, if the first attempt of decoding is unsuccessful, the receiver can receive the first signal with the first antenna in one or more second time periods and

The second signal is received by the second antenna during the second time period or the second time period. The receiver may use some or all of the channel estimates to separate the first and second data streams from at least one of the first signal and the second signal to obtain

The first separated data stream and the second separated data stream of the second time period. After separating the streams, the receiver can again attempt to decode the first and second data from the first and second separate streams of the first and second time periods.

Recall that because the TDM is used, the first signal in the second time period includes a second data stream transmitted via the first physical channel and a first data stream transmitted via the second physical channel, and the The second signal includes a second data stream transmitted by the k-th physical channel and a first data stream transmitted via the fourth physical channel. It is also recalled that the first data stream also == the first data in the second time period, and the second data stream carries the second data in the second time period of the fourth. Therefore, the data may be redundantly transmitted during the first and second time periods. The first-and second-data φ stream can be multi-point broadcasted on the shared channel or the wide-band...line grid path 605, which uses hierarchical reconciliation techniques, ten-day (ΗΜ) fork broadcast or multi-on-demand Send to UE 64〇8 and 64〇5. The fish network 405 is similar to the radio network 605 of FIG. 4 including a radio network controller 112048.doc -30-1322632 610 and cell/BTS 620, 624, 628 and 632. The cells have respective transmit antennas 621, 625, 629 and 633. The structure of the radio network controller 610 can be similar or identical to the structure of the radio network controller shown in FIG. The structure of each of the UEs 64A/A can also be the same as or similar to the structure of the ϋΕ140 shown in FIG. The radio network and UE 640A/B are configured to communicate in accordance with the methods described below with respect to this embodiment. • Here, as in the network, L, uses a generic pRAp or code reuse BLAST (CR-BLAST) machine J, and transmits % streams from the cell at any given time. These streams are carried by signals that are modulated by a hierarchy. In hierarchical modulation, a carrier is encoded in two data streams. Considering 64-QAM (Quadrature Amplitude Modulation), the data is mapped such that there is a QPSK stream included in 64-QAM. This produces two data streams: the qPSK data stream and the -16-QAM data stream. It is expected that the composite data transmission rate of the two data & can be the same as the data transmission rate of the corresponding 64-QAM data stream. For a QpsK data stream, the symbols are decoded on a carrier such that different portions of the modulation signal plane (the φ, such as the Q-I plane) of the modulation cluster represent different locations of the symbol character bits. For example, the left part of the Q# face may correspond to the "1" value-' of the most significant bit of the symbol and the right half of the plane may correspond to this bit, 〇" value. Similarly, the lower half of the plane may correspond to the value of the second most significant bit position, and the upper half of the plane may correspond to the "〇" value of the bit. Therefore, the symbol falling into the upper left quadrant will Represents the "10" in the two most significant bit positions, the symbol in the upper right quadrant will represent "〇〇" in these positions, and the symbols in the lower left and lower right quadrants will respectively represent "u&quot ; and "01" value. The symbol corresponds to the extra bit of the data stream being determined by the symbol position within a particular quadrant determined by the first two bits H2048.doc -31 - 1322632. It should be noted that the QPSK data stream is more stable than the 16-QAM data stream, which means that the QPSK data stream can be decoded with the lower SNR of the signal and the lower c/Ι ratio. The inter-cluster distance can be varied to provide additional robustness to QPSK at the expense of the 16_QAM data stream. Therefore, the more robust BPSK data stream has a larger coverage than the less stable 16-QAM data stream. In this document, the more stable layer of a hierarchical modulation signal (such as the BPSK stream in the 64-QAM example above) will be referred to as the base layer;

The less stable layer of the variable signal (such as the 16-QAM stream of the 64_qAm instance) will be referred to as the enhancement layer. Hierarchical modulation provides a mechanism for large transmission capacity. The increase in capacity is at the expense of reducing the coverage of the enhancement layer, while the performance of the base layer is improved.

In SNF 605, the stream mapping can be replaced from the base layer to the enhancement layer in time. For example, in the first time period T1 of FIG. 7, a first data stream S1 can be transmitted from the first antenna group on the basis layer of the first hierarchical modulation signal, and at the same time The enhancement layer of the second hierarchical modulation signal is transmitted from the second antenna group. In the second time period of FIG. 7, the first data stream can be transmitted from the first antenna group on the enhancement layer of the first hierarchical modulation signal and simultaneously in the second hierarchical layer The base layer of the variable signal is transmitted from the second antenna group. Thus, when the first stream is transmitted on the base layer of an antenna group, the second layer is transmitted on the same layer of enhancement layers, and vice versa. In other words: 112048.doc •32· S_ ^ I base layer V imodn = 0; 1 enhancement layer V i mod n = 1; i = stream ID; and n = OFDM symbol prime. As in the TDM embodiment of Figure 4, the data in each stream can be transmitted redundantly in successive time periods. A receiver (eg, one of the UEs 640) can be configured to receive a first received signal with a first receive antenna, the first receive signal including (1) via a first physical channel from a first transmit antenna ( Or a first transmit antenna group transmitted with a first signal component, and (2) a second signal component transmitted from a second transmit antenna (or a second transmit antenna group) via the second physical channel. The first signal component may include (1) a first base layer carrying a first data stream, and (2) a first strong layer carrying a second data stream; the second signal component may include (1) a second base layer carrying the second data stream, and (2) a second enhancement layer carrying the first data stream. The receiver can be further configured to receive with the second antenna a second signal, the second signal comprising a third signal component transmitted via a third physical channel, and (2) a fourth physical channel The fourth signal component transmitted. The third signal component may include U) a third base layer carrying the first data stream, and a third power layer carrying the second data stream; the fourth signal component may include (1) one carrier The fourth base layer of the second data stream and a fourth enhancement layer carrying the first data stream. Estimating the S-first, the second, the third, and the fourth physical channel to obtain the channels of the channels. The beta channel estimation can be performed by the receiver and is based on the pilot channel ° at some or all After the channel estimation becomes available, the receiver I12048.doc -33· can be detached from the first and second signal components. After the signal is separated, the receiver can decode the first data stream from the first base layer and decode the second data stream from the first strong layer. The receiver may attempt to decode the second data stream from both the first enhancement layer and the second base layer. Or the receiver can estimate the quality of the first signal, and if the quality of the first signal (eg, SNR) is higher than the predetermined measurement, decoding the second data stream from the first enhancement layer; If the quality of the first signal does not exceed the measurement, the receiver may use the channels to estimate the separation of the third and fourth signal components, and attempt to decode the second data stream from the second base layer. The receiver may also estimate the quality of the second signal, and if the quality of the second signal is lower than the predetermined threshold, attempt to decode the second data stream from the first enhancement layer; if the second signal The quality is not lower than the threshold, and the receiver separates the third and fourth signal components and attempts to decode the second data stream from the second base layer. Interference Cancellation (1C) techniques can be used to eliminate interference from the base layer to the enhancement layer of the same signal. In the case where multiple transmit antennas exist at Node B and must transmit a valley within a particular cell, the system can switch to spatial time transmit diversity (sttd) or turn off the transmit diversity antennas. Since the dynamic on/off transmit diversity antenna has no 1117 meaning, the first of these options may be simpler.
