Description

201132175 VI. INSTRUCTIONS: The application for this application also refers to the US Provisional Patent Application No. 61 "59, titled "Over the Air 0verload Indicat〇r", filed on March 12, 2009. The priority of No. 6〇7 is to incorporate the entire contents of the above-mentioned provisional application in this article. [Technical Field to Which the Invention Is Applicable] The present invention relates generally to the field of wireless communication. More specifically, this case is about promoting power management and control in wireless communication networks. [Prior Art] This section is intended to provide a background or context of the disclosed embodiments. The description herein may include concepts that can be implemented, but such concepts are not intended to be concepts that have been previously conceived or implemented. Therefore, unless otherwise stated herein, what is described in this section is not the prior art of the specification and claims of the present invention and is not (s) intended to be the prior art included in this section. Wireless communication systems have been widely deployed to provide various types of communication content such as voice, data, and more. Such systems may be multiplexed access systems capable of supporting communication with multiple users by sharing available system resources (e.g., 'bandwidth and transmit power'). Examples of such multiplex access systems include the Martha Multiplex Access (CDMA) system time division multiplex access (Tdma) system, a frequency division multiplex access (FDMA) system, a 3Gpp long term evolution (LTE) system, and Orthogonal Frequency Division Multiple Access (〇FDMA) system. The performance of the 201132175 wireless communication system is sometimes limited by the interference between the various transmissions that occur in the wireless network. For example, LTE system performance may be limited by cell service interval interference, particularly near the edge regions of the cell service area, where transmissions to/from devices in adjacent cell service areas may interfere with the operation of devices in the current cell service area. To reduce and/or control cell service interval interference, the LTE system may use an uplink power control mechanism such as Cell Service Interval Interference Coordination (ICIC) to improve the signal to interference ratio in the uplink channel. The overload indicator is a mechanism for facilitating coordination of the uplink cell service interval. An overload indicator is exchanged between the base stations (or evolved Node Bs) of the network, and the overload indicator provides information about the level of uplink interference experienced in one or more portions of the cell service area bandwidth. The cell service area to the overload indicator can reduce interference generated on some of the resource blocks by, for example, adjusting the transmission scheduling policy, and thereby improving the interference experienced by the cell service area that issued the or the overload indicator. • Release 8 of the LTE standard specification contains provisions for sending an overload indicator to neighboring evolved Node B via the backhaul X2. The overload indicator is made up of every resource block (RB) on the uplink— The value is constructed. The overload indicator can be further quantized into three levels indicating the level of interference experienced by neighboring evolved Node Bs on a particular resource block. According to Release 8 of the LTE standard specification, the overload indicator must be per 2〇ms is the most X2 connection on the overload indicator. However, the use of all neighboring evolution nodes B requires that in many cases, such connections may 5 201132175 Used and / or not feasible. In detail 'In the initial deployment of the LTE system, there may be no χ 2 connection between the evolved Node B. In addition, even if the X2 connection is slashable, and receiving from the proximity The overload indicator of the cell service area and the subsequent scheduling and/or power adjustment are too long. It is also very likely that waiting times such as family evolution can also be printed on the specific evolution node B of B (or HeNBs). There will be a magical connection to its neighboring cell service area. In fact, in a dense HeNB deployment, the X2 connection between the supporting macro evolution node B and all HeNBs within the coverage of the macro evolution node B may be complicated. H HeNB deployment may cause particularly severe interference conditions because user equipment cannot always be connected to its best serving cell service area. Another disadvantage associated with the current overload indication mechanism is that evolved Node B responds to the overload indicator. It is not standardized. Therefore, interference control between neighboring evolved Node Bs associated with different vendors may be impossible or may be ineffective. Such a situation report may occur in the HeNB, which is likely to have (4) (4) (4) from different vendors. In addition, the overload-based indicator command based on the loadback requires the evolved Node B to know, 'in order to implement the appropriate overload indicator for the receiver. In response, the evolved Node B receiving the overload indicator must be aware of the specific (if any) effect on the excessive interference experienced at the neighboring Node B. When the wireless channel environment is continuously received at the evolved Node B When a substantial change is made between measurement reports, such knowledge is not sufficiently established.

According to another implementation, you have not received any other air overload indicator during the ambiguous period, in which case, The adjustments correspond to user equipment: an increase in the transmit power level. For example, if the transmit power level does not exceed a predetermined threshold, the transmit power level of the user equipment is increased. In yet another embodiment, the method proceeds.

Any embodiment or § ten embodiment described herein as "exemplary" is not necessarily to be construed as preferred or advantageous over other embodiments or designs. Instead, the use of the term "exemplary" is intended to present concepts in a specific manner. Various disclosed embodiments can be incorporated into a communication system. In one example, the communication system utilizes orthogonal frequency division multiplexing (〇fdm), which effectively divides the overall system bandwidth into multiple (Nf) secondary carriers, which may also be referred to as frequency subchannels. , tone (t〇ne) or frequency band (Μη). For OFDM systems, the data to be transmitted (ie, information bits) is first encoded with a specific coding scheme to generate coded bits, and the coded bits are further classified into multi-bit symbols, such The multi-bit symbols are then mapped into modulation symbols. Each modulation symbol corresponds to a point in the set of signals defined by a particular modulation scheme for data transmission (e.g., 'M-PSK < M_QAM'). Modulation symbols may be transmitted on each of the NF frequency subcarriers at each time interval that may depend on the bandwidth of each frequency subcarrier. Therefore, 〇FDM can be used to combat inter-symbol interference (ISI) caused by frequency selective fading, which is characterized by different amounts of attenuation in the system bandwidth. r c ί 14 201132175 Line end (4) 1 wireless multiplex access (4) can support multiple wireless, -, and end communication. Each terminal transmits a communication link with one or more base switches on the way from the base to the terminal, and the reverse link = the communication link of the generation terminal to the base station . This communication key: Early input early output system, output system or multi-input multi-output (ΜΙΜΟ) system setup. The system uses multiple (Ν "solid" transmit antennas and multiple (Nr) receive antennas to transmit data. The 形成 个 transmit and NR receive antennas are formed by Ν i i & & & & & & & & & χΤ χΤ It is decomposed into Ns independent channels, which can also be called spatial channels, where "min{~, horse} each of the independent channels corresponds to one dimension. The system can provide improved performance (eg, greater throughput and/or higher reliability) if the extra dimensions of the itch Χ ΓΤ ΓΤ ΓΤ ι are established using multiple transmit and receive antennas. The JVQMO system also supports time division duplex (TDD) and crossover duplex (touch) systems. In the TDD system, 'forward link transmission and reverse link transmission are on the same frequency region' such that the principle of reciprocity allows the forward link channel to be estimated from the reverse link channel. This allows the base station to extract the transmit beamforming gain on the forward link when the base station has multiple antennas available. 1 illustrates a wireless communication system in which various disclosed embodiments may not be implemented. The base station 100 can include multiple antenna groups, and each antenna group can include - or multiple antennas. For example, if base station 100 includes six antennas, one antenna group may include first antenna 104 and second antenna 106, and another antenna group may include third antenna 108 and fourth antenna 110, ίΓί5] 15 201132175 !::Day: The group can include the fifth antenna (1) and the sixth day · 114. Wide: thinks that although each of the above antenna groups is _ is an antenna. More or fewer return references may also be utilized in the parent antenna group. The user equipment 116 is illustrated as being in communication with, for example, the fifth antenna 112 and the sixth antenna 114 to achieve via the first direction chain. The way m transmits information to the first user #116 and receives information from the first user equipment 116 via the first reverse link m. The second user equipment 122 communicates with, for example, the third day 胄1〇8 and the fourth antenna 110 to enable transmission of information to the second user equipment 122 via the second forward link 126 and Information is received from the second user device # 122 via the second reverse link 124. In a frequency division duplex (FDD) system, the communication links 118, 120, 124, 126 illustrated in Figure 1 can use different communication frequencies. For example, the first forward link 120 may use a different frequency than that used by the first reverse link 118. In some embodiments, each antenna group and/or the area in which it is designed to communicate is often referred to as a sector of a base station. For example, the different antenna groups shown in Figure 1 can be designed to communicate with user equipment in the sector of the base station. In communication via forward link 120 and forward link 126, the base station's transmit antennas are beamformed to facilitate improved forward routing for different user equipment 116 and user equipment 122. Signal ratio. In addition, the use of beamforming to transmit to a user equipment that is randomly distributed throughout the coverage area of the coverage area causes less interference to user equipment in the adjacent cell service area than to a full antenna via a single antenna. The equipment is equipped with a base station that transmits to interfere with user equipment in the adjacent cell service area. Communication networks that can implement the various disclosed embodiments can include logic channels that are classified into control channels and traffic channels. The logical control channel may include: a Broadcast Control Channel (BCCH), which is a downlink channel for broadcasting system control information; a Paging Control Channel (PCCH), which is a downlink channel for transmitting paging information; and a multicast control channel ( MCCH), which is a point-to-multipoint downlink channel for transmitting Multimedia Broadcast and Multicast Service (MBMS) scheduling and control information for one or several Multicast Traffic Channels (MTCH). In general, after establishing a Radio Resource Control (RRC) connection, the MCCH is only used by user equipment that receives the MBMS. The Dedicated Control Channel (DCCH) is another logical control channel that is a point-to-point bidirectional channel beta shared control channel (CCCH) that transmits dedicated control information, such as user-specific control information used by RRC-connected user equipment. It is a logical control channel that can be used to access information randomly. The logical traffic channel can include a dedicated traffic channel (DTCH), which is a point-to-point bidirectional channel dedicated to a user's equipment for transmitting user information. In addition, a Multicast Traffic Channel (MTCH) can be used for point-to-multipoint downlink transmission of traffic data. Communication networks in which various embodiments may be implemented may additionally include logical transmission channels. The logical transmission channels are divided into a downlink (DL) and an uplink (UL). The DL transmission channel may include: a broadcast channel (BCH), a downlink shared data channel (DL-SDCH), a multicast channel (MCH), and a paging channel (PCH). The UL transmission channel may include: a random access channel (raCH〇S} 17 201132175 request channel (REQCH), an uplink key shared data channel (UL-SDCH), and a plurality of physical channels.

One of ordinary skill in the art will appreciate that even if the base station represents the transmitter system 210 and the user equipment represents the receiver system 250 as shown, embodiments of such systems are capable of two-way communication. In this regard, the terms "transmitter system 2 10" and "receiver system 250" should not be used to imply one-way communication from either system. It should also be noted that the transmitter system 210 [product] 22 201132175 receiver system 25 of Figure 2 is each capable of communicating with a plurality of other receiver systems and transmitter systems not explicitly illustrated in FIG. A plurality of data streams of traffic data are provided from the data source 212 to the transmit (TX) data processor 214 at the transmitter system 21'. Each data stream can be transmitted via a separate transmitter system. The TX data processor 214 formats, codes, and interleaves the traffic data for each data stream based on a particular encoding scheme selected for each data stream to provide encoded data.

In one example, each detected symbol stream can include a symbol, ^, etc., an estimate of the symbol transmitted for the corresponding data stream. The RX data processor 260 then at least partially demodulates, deinterleaves, and decodes each detected symbol to recover the corresponding data stream of the data stream. The processing performed by the RX data processor 26 can be reversed from the processing performed by the τ χ processor 220 and the TX data processor 214 at the transmitter system 21 。. The RX data processor 260 can additionally provide the processed data stream to the data slot 264. ^ ρ 24 201132175 In some embodiments, the channel response estimates generated by RX data processor 260 can be used to perform spatial/temporal processing at receiver system 250, adjust power levels, change modulation rates or schemes, and/or other Appropriate Actions In addition, Rx data processor 260 can further estimate channel characteristics, such as the signal-to-noise ratio (SNR) and signal-to-interference ratio (SIR) of the extracted symbol stream.

In one example, Rx data processor 260 and/or processor 27A of receiver system 25A may further derive an estimate of the "operating" SNR of the system. Processor 270 of receiver system 250 may also provide channel status information (CSI) 'which may include information about the communication link and/or receive data string 1 transmitter system 2 1 0 (eg, base station or evolved node) b) This information (which may include, for example, operational SNR and other channel information) may be used to make appropriate decisions regarding, for example, user equipment scheduling, MIM settings, modulation and coding selection, and the like. At the receiver system 25A, the CSI generated by the processor 270 is processed by the TX data processor 238, modulated by the modulator 280, adjusted by the receiver system transceiver 25, and sent back to the transmitter system 210. . In addition, the data source 236 at the receiver system 25 can provide additional information that is processed by the TX data processor 238. In some embodiments, the processor 27 at the receiver system 250 can also periodically decide which precoding matrix to use. The processor 27 formulates a reverse link message including a matrix index portion and a rank value portion. The reverse link message may include various types of information about the communication link and/or the received data stream. After h, the data processing at the receiver system 250 can be followed by the processing of the reverse link message, which receives the data stream from the data source 236. Information. The resulting information is modulated by modulator 280, regulated by one or more receiver system transceivers 254a through 2541, and sent back to transmitter system 21A. In some embodiments of the communication system 200, the receiver system is capable of receiving and processing spatial multiplex signals. In such systems, spatial multiplexing occurs at the transmitter system 210 by multiplexing and transmitting different data streams on the transmitter system antennas 224a through 224t. This is in contrast to the use of the transmit diversity scheme. In the transmit diversity scheme, phased data streams are transmitted from multiple transmitter system antennas 224a through M24t. In a chirp communication system 200 capable of receiving and processing spatial multiplex signals, a precoding matrix is typically used at the transmitter system 210 to ensure that signals transmitted from each of the transmitter system antennas η blunt to 224t are sufficiently resolved from each other. Related. This decorrelation ensures that it is capable of receiving composite signals arriving at any particular receiver system antenna 252 &252r; and in the presence of signals carrying other data streams from other transmitter system antennas 224a through 224t, it is possible to determine individual Data stream. Since the dilemma can affect the amount of cross-correlation between streams, it is common for the receiver system 250 to feed back information about the received signals to the transmitter system 210. In such systems, both transmitter system 21 and receiver system 250 include codebooks having a number of precoding matrices. Each __ in these precoding matrices may in some cases be related to the amount of cross-correlation experienced in the received signal. Since the advantageous case is to transmit the index of the particular matrix rather than the value in the matrix, the feedback control signal sent from the receiver system 25 to the transmitter 26 201132175 system 210 typically contains an index of the particular precoding matrix in some cases' The feedback control signal also includes a rank index 'which indicates how many independent streams of data the transmitter system 2 will use in spatial multiplexing. Other embodiments of the communication system 200. are configured to utilize a transmit diversity scheme in place of the spatial multiplex scheme described above. In these embodiments, the same data stream is transmitted on the transmitter system antennas 224a through 224t. In these embodiments, the data rate to the receiver system 25 is typically lower than the spatial multiplex communication system 200. These embodiments have advantages in terms of health and reliability of the communication channel. In a transmit diversity system, each of the signals transmitted from the transmitter system antennas 224a through 224t will experience different interference dips (fading, reflection, multipath phase shift). In such embodiments, different signal characteristics received at receiver system antennas 252a through 2521 can be used to determine the appropriate data stream. In such embodiments, the rank indicator is typically set to 1 to inform the transmitter system 21 that no spatial multiplexing is used. Other embodiments may utilize a combination of spatial multiplexing and transmit diversity. For example, in a wireless communication system 200 using four transmitter system antennas 224a through 224t, a first data link can be transmitted on two of the transmitter system antennas 224a through 224t, and the transmitter system antenna can be used. A second data stream is transmitted on the remaining two antennas of 224a through J 224t. In such embodiments, the rank index is determined to be an integer 'below the full rank of the precoding matrix' thereby indicating that the transmitter system 21 is using spatial multiplexing and transmit scores 27 201132175 at the transmitter system 210, from the technical flux The modulation signal of the %%% Mumu receiver system 25〇 is received by the transmitter system antennas (10) to 224t, regulated by the transmitter system transceivers 222a to 222t, demodulated by the transmitter system demodulator, and processed by the U data. The processor 242 processes to extract the reverse link message transmitted by the receiving system. In some embodiments, the processor 230 of the transmitter system 21 then determines which precoding matrix (4) to forward the forward link. And subsequently processing the extracted information. In other embodiments, processor 230 uses the received signal to adjust beamforming weights for future forward link transmissions. In other embodiments, the reported CSI may be provided. The processor 230 of the transmitter system 210 is used to determine, for example, the data rate and coding and modulation scheme for one or more data streams. Subsequently, the determined coding and The scheme may be provided to one or more transmitter system transceivers 222 & 222t at the transmitter system 21 for quantization and/or for later transmission to the receiver system 250. Additionally and/or Alternatively, the processor 230 of the transmitter system 21A can use the reported CSI to generate various controls for the τχ data processor 214 and the τχ ΜΙΜΟ processor 22〇. In one example, the RX data processor of the transmitter system 210 The CSI and/or other information processed by 242 may be provided to data slot 244. In some embodiments, processor 23 at transmitter system 210 and processor 270 at receiver system 250 may indicate their respective systems. In addition, the memory 232 at the transmitter system 210 and the memory 272 at the receiver system 25 can provide code and data for the transmitter system processor 23 and the receiver system processor 270, respectively. In addition, at the receiver system 250, 'NR received signals can be processed by various processing techniques' to detect Ντ transmitted symbol streams. These receiver processing techniques These may include: spatial and spatial-temporal receiver processing techniques, which may include equalization techniques, "continuous zeroing/equalization and interference cancellation" receiver processing techniques; and/or "continuous interference cancellation" or "continuous cancellation" receiver processing _technology. FIG. 3 illustrates a wireless network 300 in which various disclosed embodiments may be implemented. The exemplary wireless communication system 300 includes a plurality of cell service areas including a cell service area 302, a cell service area 3〇4, and a cell service area 306. The cell service area 3, 2, cell service area 304 and cell service area 306 of the communication network 300 can include a base station that includes a plurality of sectors. The plurality of sectors may be formed by groups of antennas, wherein each antenna is in negative communication with one or more user equipment in a portion of the cell service area. For example, in the cell service area 3〇2, the antenna groups 312, Η#, and 316 may each correspond to different sectors. In the cell service area 3'4 antenna groups 318, 320 and 322 each correspond to a different sector. In cell service area 306, antenna groups 324, 326, and 328 each correspond to a different sector. The cellular service area 3〇2, the cell service area 304, and the cell service area 3〇6 of the communication network may include a number of wireless communication devices, such as 'to enable the device to be equipped' with each of the communication networks 3 One or more sectors of the cell service area 302, the cell service area 3〇4, or the cell service area 3〇6 communicate. For example, the squatter equipment 330 and the user _ 332 can communicate with the base station 342, the user equipment 334 and the user equipment 336 can communicate with the base station 344, and the user equipment 3 moxibustion 8 29 201132175 and the user Equipment 340 can communicate with base station 346. Figure 3 is also a diagram: System control for communication with one or more base stations of the communication network _ 1 3 3 0. As described above, in a communication network such as the wireless communication network illustrated in FIG. 3, the base station can transmit an overload indicator via the Χ2 back to the base station of the adjacent cell service area to facilitate provisioning in the cell service area. Information on the uplink interference experienced in the bandwidth - or multiple parts. The cell service area receiving the overload indicator (hereinafter "Receiving Cell Service D, the response is not standardized" and is therefore determined by the implementer of the base station. However, in a typical response case, the receiving cell The service area β' reduces the interference generated on some resource blocks by, for example, adjusting the scheduling strategy for the transmission of the user equipment, reducing and/or reallocating the transmission power of the user equipment, or a combination thereof. The degree of interference caused by, for example, user equipment may be based. To assess the degree of interference 2, the receiving cell service area may rely on differential path loss measurements, which are calculated from the measurement reports sent by the user equipment. For example, the overload indicator in the LTE network enables the network to maintain the interference experienced at each evolution point, at the desired value or below the desired value, often with respect to the thermal noise of the evolution node. The level (heart 1 l^el) is used to measure the interference level and is called the interference and thermal noise ratio (ι〇Τ). & Strict control has several For example, the predictable ι〇τ level enables the network to perform accurate rate prediction in data channels such as pusCH. This is also inconsistent with hybrid self-repetitive spray (HARQ) retransmissions such as pucCH. Related to the control channel. In the absence of strict [G] 30 201132175 ι〇τ control, it may be necessary to send the information transmitted on these channels with very conservative power levels. A very conservative power level can lead to Transitional interference to other evolutionary nodes. It should be noted that although in some implementations PUCCH is primarily susceptible to "control-〇n-control" interference, in addition to different PUCCH regions in neighboring evolved Node B In addition to the range of interference, control information is often subject to interference from the data channel due to transmissions on the PUSCH. The high interference level observed at the evolved Node B can further affect the user equipment served by the evolved Node B. Link budget, the link budget impact can lead to: data interruption 'for example, caused by my loss of ip-based voice (VoIP) packets Data interruption; and control interrupts, which may include loss of channel quality information (CQI) reports and ACK/NACK information. The overload indicator at the receiving cell service area may be further used to implement power shaping using a power control algorithm, These power control algorithms utilize differential path loss information from the user equipment. In particular, in such schemes, user equipment located near the edge of the cell service area can transmit at a relatively low power spectral density (due to its It is the primary interferer), and user equipment that is not located near the edge of the cell service area can transmit at a higher power spectral density (because it results in relatively lower interference). This type of power shaping can help increase the network. capacity. It should be noted that the term "power spectral density" can refer to a power value normalized by the bandwidth (e.g., a constant multiplied by the power on each resource block). For example, the transmit power of a device that transmits 31 201132175 can be proportional to the number of resource blocks allocated to the user equipment multiplied by the power on each resource block. Therefore, by controlling the power spectral density, Control of the transmit power of the user equipment can be achieved 'by controlling the power spectral density, the control of the transmit power on each resource block can be achieved. However, as also noted above, for various reasons, it may not be feasible to transmit an overloaded private indicator via the χ2 interface and to receive subsequent actions of the cell service area for power control. For example, connectivity between various base stations may not be available. In addition, even if χ2彳 is available, the waiting time associated with such communications may be too long. In addition, if the channel interference condition varies between successive measurement reports, the power control/adjustment by the base station may not adequately mitigate such channel interference conditions. Various disclosed embodiments provide systems, methods, apparatus, and computer program products that enable transmission of an over-the-air indicator to facilitate uplink power control in a wireless communication system. FIG. 4 illustrates a system 400 that uses an overload indicator component 440 in a wireless network 41 根据, in accordance with an exemplary embodiment. System 400 includes one or more base stations 42 (also referred to as nodes, evolved Node B (eNB), serving eNB, target eNB, femto station, pico station, relay base station, etc.), which may be capable of being wireless The network 41 is an entity that communicates with one or more devices 430. For example, each device 43 is equipped with a user (also referred to as a terminal, an access terminal, an active management entity (MME), a mobile device, etc.). The base station 42A can include an overload indicator component 440 that is configured to generate and/or handle overload indications on the wireless network 41. A portion of the overload indicator component 44 at the base station 420 may also be configured to generate an overload of the device and the device (such as η _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ indicator. User line network 41. The upload indicator component is 45°, which is configured to handle wireless, and the overload indication on the peripheral path 410 is determined to be "small". Although Figure 4 illustrates the overloaded indicator component. The two components 42〇_43〇, but the °P pieces on the two ^-T v * ^ . may also be used on the network 410, wherein such additional components may also be configured to perform various operations as described herein. Different signal processing operations. As shown in Fig. 4, the base σ 420 makes a talk to the device 430 via the downlink 460, and receives the data via the uplink 47 。. Since the device 430 can also transmit data from the lower link and receive data via the uplink, such designation of the subscribed link and the downlink is arbitrary. In some embodiments, the airborne overload indicator can be transmitted by the evolved Node B that is experiencing a high interference level and received directly by the multiple devices in the wireless communication network. For example, referring to FIG. 4, the overload indicator may be generated by the overload indicator component of the base station 420 and sent directly to one or more users to borrow Iky, and the base σ 420 may be associated with the cell service area in the communication network 410. And the one or more devices 43 may be in a neighboring cell service area. Subsequently, the airborne overload indicator received by the user equipment may be processed by the overload indicator component 450 of the device 430 to facilitate Power Control. In a second embodiment, in addition to using other information such as power control commands received from the service base port of the device (four), the device also uses (iv) an air overload indicator received from a neighboring cell service area to determine the position 33. The transmit power is implemented in 201132175. In addition, the device 43() can also receive the overload indicator information received by the service base station, so that the service base station knows the interference that the adjacent cell service area is experiencing. The method can realize interference control between the base stations even in the absence of the Χ2 connection. In addition, since the device 43〇 The overload indicator is directly received and the response of the device 430 to the overload indicator is fully specified, so that interference control between base stations from different vendors can also be successfully performed. Furthermore, the device 430 is ready to overload the indicator with the air. The latest measurements of its radio frequency (RF) environment can be utilized when responding appropriately. Figure 5 is a block diagram illustrating an exemplary embodiment. Method 5 begins at 502 when the user is equipped from one or more neighboring cells The service area receives one or more airborne overload indicators. In response to receiving the one or more airborne overload indicators, the user equipment determines at 504 an adjustment to the transmit power of the user equipment to facilitate reducing or eliminating interference. In some embodiments, by way of example, but not limitation, such adjustments may include modifying the transmit power value, making adjustments to the transmit schedule, and/or redistributing the frequency for transmission of the user equipment. Performing at least some of the above adjustments, for example, specific changes to the transmission schedule and/or bandwidth. Therefore, the user equipment can request the base station These adjustments are now made. At 5〇6, the user equipment can optionally report the above adjustments to its service base station. Finally, at 5〇8, the user equipment can implement power control based on these adjustments. The above blocks and operations are for illustrative purposes. The disclosed embodiments are not limited to the exemplary blocks and may be implemented with fewer or more blocks and operations. For example, although the exemplary block diagram of FIG. The independent 10,000 blocks that are used to determine the power control, but it is entirely possible to combine these operations into one step, for example, in step 504. According to another embodiment , _ a, λ sigh 43 〇 can first calculate the power spectrum based on the received empty t overload indicator. The power spectrum density that can be transmitted by the power spectrum ancestor n can be sent to The service base station, which is also given the opportunity to modify the calculated transmit power density. For example, the service base station may need to modify the power to read to allow certain high priority traffic to pass within a particular delay budget. It should be noted that according to this embodiment, the overload indicator is transmitted to the device 43q and its service base station without using the Χ2 " However, since both the device 43 and its serving base stations are involved in determining the transmit power', additional latency and uplink data management burden can affect the power control operation. Figure 6 is a block diagram illustrating an exemplary embodiment including some interaction between a user's sitter and its serving base station. The method begins at 6〇2, at which point the user equipment receives an airborne overload from one or more adjacent cell service areas. “In response to receiving the—or multiple airborne overload indicators, the user equipment is at 604. The adjustment of the transmit power is used to reduce or eliminate the interference. The user equipment reports the calculated transmit power adjustment to its service base station at 606胄. At 6〇8胄, the user equipment can receive from the service base station. Modified transmit power, adjustment. Modified adjustments received from the serving base station may include new transmit power adjustments and/or commands necessary to implement such adjustments, or no need to perform any previously calculated transmit power adjustments The change is not. If it is not necessary to calculate the Lingler 35 201132175 for the user equipment, the change can be changed 'alternatively' at 608, the user equipment can receive no additional information only for example within a predetermined period. Finally, at 6 i ,, the user equipment can implement power control based on updated transmit power adjustments and/or commands. In another embodiment Device 430 can receive one or more airborne overload indicators and then report the received information to its serving base station. The service base station can then be based on the received overload indicator and other information (such as by wireless network 410). One or more user equipment sends an I test report) to calculate an appropriate transmit power adjustment. Subsequently, a power control adjustment/command can be sent from the serving base station to device 430 to effect transmit power control at device 430. In this embodiment, although the overload indicator information exchange can be performed without the need for a face, the power control adjustment/command generated by the service base station may be susceptible to the expiration information related to the rule environment. If the base station's response to the received overload indicator is not specified or is not part of a standardized agreement, some base stations may not respond to these overload indicators. Therefore, the ability to control interference in multi-vendor deployments may be lost. Figure 7 is a diagram illustrating an adjustment/command based on receipt from a serving base station. The rate control is a block diagram of another exemplary embodiment. Method 700 begins #702, at which point the user equipment receives one or more airborne overload indicators from one or more neighboring cell service areas. In response to receiving the one or With multiple airborne overload indicators, the user equipment reports overload indicator information to its service base station at 7.4, and calculates appropriate power control adjustments in the service base station. At 7〇64 'money equipment from its service base Station reception [transmit] 36 201132175 Radio power adjustment. The transmit power adjustment received from the base station may include new transmit power adjustments and/or commands necessary to achieve such adjustments. Finally, where the user equipment is based on the received adjustments The transmission power control is implemented. It will be apparent from the above description that the calculations performed according to the embodiments illustrated in Figures 5 and 6 are performed primarily at the user's injury, while the embodiment according to the embodiment depicted in Figure 7 The calculation used to determine the transmit power level is primarily performed at the base station. Additionally, in conjunction with the embodiment illustrated in Figure 7, the exact algorithm used to determine the power control commands at the base station may not be specified. Figure 8 is a block diagram illustrating operations that may be performed for generating an empty overload indicator, in accordance with another embodiment. Method 8 begins with (iv), where an overloaded finger = Beixun is produced at a cell service area that has experienced high levels of interference. The content of the overload indicator information may be the same as the existing overload indicator sent to other base stations via the internal interface of the back: the same. Or the content of the 'over-the-air overload indicator' may include a subset and/or a compressed version of the information contained in the general super binary. The content of the overload indicator in the further substitute can include information other than the information contained in the general overload indication. In one example, the overload indicator is outside the second; the carry value ' indicates the presence or absence of an overload/interference condition. The other phase can provide information about the overload conditions associated with a particular time and/or frequency resource. The fly material is negatively sourced. Example:::; At 804, the format operation of the overload indicator information may not be limited. In some embodiments, format interleaving, two-source encoding, channel encoding, modulation encoding, error correction encoding, and / or overload indicator information ready for transmission _ 37 201132175 Other # material formatting and adjustment operations. At 806, the overload indicator 'X sends,' or multiple user equipment. The one or more user equipment can be located in one or more adjacent cell service areas. After receiving the air overload indicator, the user device # can respond by the power rate control operation. A method for implementing transmit power control: the method can be based on a transmit power adjustment calculated using a "falling or ((10)." (four) η)" / 寅 algorithm #. According to the "declined or" shoulder f method, when used When the device receives a drop j (DOWN) request from any of a plurality of base stations, the user equipment can reduce its power rate. However, only when the user equipment receives "up" (UP) from all base stations. The user equipment increases its transmit power. In some embodiments, the user equipment is equipped when the user equipment is connected from any adjacent, field service area (4) empty towel overload indicator. The transmit power can be reduced by a fixed step size ~. In addition, the user equipment can increase its transmit power level only when the user equipment fails to receive any overload indicator within the time period of the beat. The fixed step size can implement the above power control algorithm at, for example, the Medium Access Control (MAC) layer. In order to provide meaningful limits on the maximum and minimum transmit power levels, it can be served The SNR obtained at the base station establishes two signal ratios _ and SNRmin. The upper limit implicit_ ensures that the user equipment* transmits at a power level greater than the power level required to obtain peak spectral efficiency. Similarly, The lower limit bribe ensures that each user's equipment is able to obtain a specific minimum read. This algorithm allows the network to control the 狮 38 201132175 at each base station. However, due to all user equipment in the network All respond to the overload indicator in a similar manner 'so the power shaping gain cannot be obtained via this algorithm. To obtain the power shaping gain' the response of the user equipment can be based on the amount of interference being caused by the user equipment. In some embodiments, the power shaping gain is provided using a differential path loss Apl, which represents the interference caused by the user equipment. The pinch loss typically represents the loss of signal strength caused by propagation. With a given configuration of the user equipment, the differential path loss can be determined as PLeNB - PLeNB, serv. Here, PLeNB The dB scale represents the path loss between the user equipment and the base station that is experiencing high interference levels and the PLeNB, serv represents the path loss between the user equipment and its serving base station in dB scale. In some embodiments, Combining the probability of use is the path loss to determine the appropriate transmit power adjustment, and then implementing transmit power control at - or multiple user equipment in the wireless network. In one example, after receiving the overload indicator, The user equipment 17 reduces its transmit power level by a fixed step size Δ according to the probability pd() wn(ApL, SNR). In this example, the probability pd_ is based on the SNR and differential path loss obtained at the serving base station. ^Depending on the general, the probability of not doing any action is the pd_. Similarly, when no overload indicator is received, the user equipment can increase its transmit power level by the probability Pupcpl, snr) in the example, the probability Pup- also, according to the service base station Get the prison and ^ points path loss ~ and oh. When no overload indicator is received and there is only one [off] 39 201132175 near-base station, the differential path loss relative to the neighboring base station can be calculated. If there are multiple neighboring base stations, the probability value may be based on A plurality of differential paths (four) determined by a plurality of adjacent cell service areas depend on the value. It should be noted that the path loss for neighboring base stations can be measured even if no overload indicator is received. In some exemplary embodiments, the 'probability function Pup(apl, Snr) may be selected such that when the differential path loss APL is low and/or when the SNR is high, the probability function Pup is low, and the probability function P6Wa (APL, SNR) ) can be chosen such that it behaves in the opposite way. For example, these attributes are satisfied by the following function: Pup(ApL, SNR)==a(l-b);

Pd〇wn(ApL, SNR)=(l-a)b; b=(SNR-SNRmin)/(SNRmax_SNRmin). In the above example, the W dB scale is used for calculation. ^PL,min and PL,max represents the upper and lower limits of the differential path loss Δ ^ PL , , , , , , , , , , , , , , , , , , , , , , , , , , , , , , , , , , , , , The above-mentioned probabilistic response of the controller (4) to the overload indicator also has the advantage that it reduces and/or eliminates potential vibrating behavior in the network. Such oscillatory behavior may occur when a large number of user equipment simultaneously increases or decreases their transmission power. In a variation of the above embodiment, when the oil receiving device receives an evening overload indicator from the plurality of cell service areas, the user's response to the equipment may include: hanging in the received overload indicator Each parent decides the associated power adjustment value and/or probability PdQwn value; and selects a specific Du, Li Gan adjustment value and/or a specific probability Pd own value to reduce borrowing of the skin 1 degrading user The transmit power of the equipment. [傅 201132175 For example, you can choose the maximum power adjustment value. In another variation, when no overload indicator is received within a specified time period, one or more power adjustment values and/or probability Pup values may be determined, and the power adjustment value and/or the particular one may be selected. Pup value for increasing the transmit power of the user equipment. In one example, the power adjustment value corresponding to the closest non-serving base station can be selected. In accordance with the disclosed embodiments, the mid-ship overload indicator is transmitted in a manner that enables a plurality of user salvage in a plurality of adjacent cell service areas to receive and demodulate an air (four) indicator. Therefore, the airborne overload indicator must be decodable at low SNR. In an exemplary embodiment, the penetration of the airborne overload indicator is at least similar to the penetration of the primary synchronization code (PSC) and the secondary synchronization code (ssc). The edge of the psc卩ssc channel requires that the user's equipment should be able to take a base station with -6dB SNR for a limited period of time. The aerial overload indication is provided at a penetration level similar to psc and ssc, and it is expected that the overload indicator will be properly received and demodulated by different user devices. However, the air overload indicator can also be measurable at lower SNR values because it allows the user to spend more time to debunk the signal. In addition, although the overload indicator is often received at very low SNR, the overload indicator may be able to tolerate a larger erase rate "rate" than other control channels. Various disclosed embodiments also enable the user to The airborne overload indicator is demodulated with the additional computational complexity of the smear. In a particular embodiment, the base station downlink key can be used in the LTE network [Road] 201132175 The central six of the transmission bandwidth An air overload indicator is sent on the resource block. The user equipment typically monitors the bandwidth from the neighboring cell service area to detect the new base station and track the detected base station. Therefore, the pair is transmitted on the same bandwidth. The extra overload indicator value is demodulated, which will cause a relatively small change to the user equipment implementation. The embodiment disclosed by the grain type, 丨~, 丨·· q clothing two battery life impact minimal solution Adjust the air over-balance indicator. In the coffee system, 'user equipment can be in discontinuous reception (drx) _ type to protect the battery life of the user equipment. Although in the Cong mode At least part of the user equipment may be interrupted during the extended (four) period, and the user equipment occasionally monitors the downlink and/or uplink. In addition, the signal product f from the serving base station is degraded, The user equipment can broadcast the neighboring base station. In this case, the caution & sweep can be sent to the air overload indicator, so that the user can perform the neighboring point tracking when the user equipment performs the neighboring point tracking, for example, because the user The equipment has been sub-sourced to the LTE frame: line monitoring for neighbor tracking, so the airborne overload indication can be sent on this δ to be used to send the air to catch up. ^ Instance 5 Compared with the subframe 0, the subframe 5 is adjacent to the resource that accommodates the overload indicator, because the subframe 〇e contains the physical broadcast channel (PBCH), the target is the subframe, and the overload indicator is already used. If the transmission period is set to be greater than or equal to the block (10), the system information area ^1) can be avoided on the subframe. The parent interval is 20 ms in the sub-frame s μ + "sub-frame 5... change to frame 5 On (that is, in alternating sending coffee. Therefore, if overloaded The indicator Zhou Si is 42 201132175 selected as 20 ms or more, then it can be , . . . ] to send the overload indicator on the subframe 5 not used for SIB1 transmission. SIm Yourstone* contains · Information related to cell service area access (such as public information - PLMN, cell service area identity, etc.), and information for cell use, field service area selection, row Program information and other system information. Another: Bu, can allow users in DRX mode to monitor the subset of airborne overload transmissions to further protect their battery life. For example, = get and LTE via backhaul transmission The report with the same overload indicator 'user equipment can be monitored every 20 ms—an air overload indicator. It should be noted that it is also possible to choose a monitoring cycle that is different from the 2-mail post. Alternatively or alternatively, the network configuration does not allow the user equipment to operate in the DRX mode while transmitting data on the uplink, the user equipment can ignore the overload indicator transmission during the uplink transmission. In this case, the base station can assign a conservative initial power value (e.g., based on an open loop projection) for uplink transmissions that occur after a long magnetic period. According to another embodiment, an air overload indicator may be transmitted in more than one of the six central resource blocks of the subframe. For example, two resource blocks can be used to transmit an airborne overload indicator. In addition, the overload indicator can be channel encoded into, for example, a pseudo-random sequence prior to its transmission. According to another exemplary embodiment, the SSC can be used as a phase reference for demodulating airborne & For example, BPSK modulation and a beam for ssc can be used to transmit a one-bit overload indicator, that is, an air overload. Fingerprint 43 201132175 The indicator can use the same phase or different phase as ssc, and the same beam direction. (in the case of multiple transmit antennas). When using SSC as a phase reference, as opposed to using a common reference symbol (RS), even if the cell service area has more than one transmit antenna, only the user is required to borrow to obtain a single channel estimate. In addition, the density of ssc in the central six resource blocks is greater than the density of the shared RS. Therefore, channel estimation losses are minimized. In another embodiment, the airborne overload indicator can be transmitted as the phase between the Rs #number combination and the S S C . It should also be noted that user equipment can use a simplified detection algorithm. For example, after an optional appropriate subtraction, the time or frequency correlation between ssc and a dedicated Rs symbol with an overload indicator symbol can be used. To reduce hardware complexity, the user equipment can use components that have been implemented as part of the LTE search engine and/or measurement reporting engine, such as time alignment with new sectors, search engine detection, FFT engine, and the like. In addition, in order to improve the channel estimation performance, an additional pilot frequency fee can be used in the resource block for the transmission of the overload indicator. Figure 9 illustrates the insertion of a frequency 丄 pilot symbol in an exemplary single antenna LTE subframe of the 4 3 normal cyclic word first code. The sub-frame illustration on the left side of Figure 9 shows the case where mc is used as a pilot without additional pilot symbols. The right side of Figure 9: block illustrates additional pilot frequency symbols that have been inserted in accordance with an exemplary embodiment. FIG. 1A illustrates another exemplary embodiment, which is similar to FIG. 9, except for the destination '/extended cyclic prefix encoding, which replaces seven symbols with six symbols from each time slot. )As can be seen. An exemplary performance curve (i.e., error rate vs. snr [躇 44 201132175]) is associated with an air overload indicator transmitted using a single resource block with or without additional pilot symbols. Figure 11 also shows the difference between the performance of the mobile user equipment speed based on 3 Krn per hour and the performance of the mobile user equipment speed based on 6 Km per hour. From Figure 11, it can be seen that 'even when a single When the resource block is used to transmit the airborne overload indicator, it can also obtain an error rate of about 6% at _i 0 dB SNR. When the extra pilot symbol is used, the error rate at _丨〇dB SNR is improved to about 2%. Figure 12 illustrates a similar performance curve for the case where two resource blocks are used to transmit an airborne overload indicator. Figure 12 further illustrates the error rate improvement due to the use of additional resource blocks. In some embodiments, if the user equipment monitors a plurality of air indicators from a plurality of cell service areas having similar but de-synchronized timings, the user equipment can select overloads received from different cell service areas. The indicator is subsampled. Subsequently, the user equipment can apply additional steps (ie, transmit power adjustments, ~_ and ~) to respond to the subsampled overload indicator, for example, if the user is equipped at a half-normal rate Monitoring the overload indicator, the size of the transmit power adjustment can be doubled. Alternatively or alternatively, the cell service area can choose to send an air overload indication ^ in a subframe within its location that changes over time within the radio frame. Thus preventing duplicate overload indicators from being sent at the user equipment: the overload indicator on the rush can correspond to: - carrier or carriers. In addition, multiple overload indicators covering different carriers can be transmitted on the same downlink carrier. According to (4) 45 201132175 embodiments, when multiple overload indicators are transmitted on one downlink carrier, different resource blocks may be used to transmit overload indicators associated with different carriers. In another exemplary embodiment, an overload indicator can also be used to control interference caused by adjacent carrier leakage ratio (ACLR). ACLR is often associated with situations where user equipment transmitting on the carrier 造成 interferes with the transmission of carrier 2. According to another exemplary embodiment, the same or different overload indicators can be used to control co-channel interference and ACLR. According to various disclosed embodiments, the use of an airborne overload indicator improves the interference to thermal noise ratio (ι〇τ) cumulative density function (CDF) and allows for the IGT level observed at each base station. strict control. Such improvements are particularly evident for smaller cell service areas. Strict control of the IOT level ensures that the control channel for the data channel and for transmission on, for example, the Physical Uplink Shared Channel (PUSCH) (eg, when transmitting PUCCH and PUSCH in the same subframe) can be maintained Fit #'s key budget. In addition, the control of the IoT improves the SNR predictability in the subframes. This leads to more accurate prediction of the data rate and, more importantly, ensures reliable transmission of the control channel on the PUSCH resources. Control reception. In addition, in accordance with various disclosed embodiments, the use of an airborne overload indicator significantly improves the performance of user equipment at the edge of the cell service area when power shaping is achieved. If power shaping is not used, the fairness improvement caused by the use of the overload indicator may be accompanied by a loss of throughput in the total cell service area. In accordance with the disclosed embodiments, the use of power shaping has improved] 46 201132175 total cell service area throughput' while maintaining improved edge device performance. In particular, in accordance with the disclosed embodiments, the use of power shaping allows the cell service area throughput to be maintained at a level that is nearly identical to the cell service area throughput without any overload indicator.
