200835361 IX. DESCRIPTION OF THE INVENTION: TECHNICAL FIELD OF THE INVENTION The following description relates generally to wireless communications, and more particularly to sub-band scheduling and power amplifier back-shifting. [Prior Art] _ Wireless network connection system has become a common means by which most people in the world communicate. Wireless communication devices have become smaller and more powerful to meet consumer needs and to improve portability and convenience. Consumers have become accustomed to sin services, expanded coverage areas, and increased functionality, depending on wireless communication devices such as cellular phones and personal digital assistants (PDAs). In general, a wireless multiple access communication system can simultaneously support communication for multiple wireless terminals or user equipment. Each terminal communicates with one or more access points via transmissions on the forward and reverse keyways. The forward link (or downlink) refers to the communication link from the access point to the terminal, and the reverse link (or uplink) refers to the communication link from the terminal to the access point. A wireless system may be a multiple access system capable of supporting communication with multiple users by sharing available blunt resources (e.g., bandwidth & transmission power). Examples of such multiple access systems include code division multiple access (CDMA) systems, time division multiple access (TDMA) systems, frequency division multiple access (FdmA) Qin systems, and orthogonal frequency division multiple access (OFDMA) )system. Usually 'each access point supports a terminal located in a specific coverage area called a sector. A sector that supports a particular terminal is called a serving sector. Other sectors that do not support <=special terminals are referred to as non-serving sectors. Specific resources can be configured to terminals in an area to allow multiple terminals to be supported at the same time. 126198.doc 200835361 However, the value is made by the terminal in the neighboring sector. Therefore, the transmission by the terminal at the edge of the sector can cause interference and degradation of the terminal performance in the sector.

Mobile devices, mobile stations, mobile devices, user terminals, and in addition to the mobile devices described herein, may also be referred to as systems, subscriber units, subscriber stations, remote stations, remote terminals, and access terminals. Terminal, wireless communication device, user agent, user device or user equipment (UE).

Moreover, various embodiments are described herein in connection with a base station. A base station can be utilized for communicating with a mobile device and can also be referred to as an access point, Node B, or some other terminology. In addition, the various aspects and features described herein can be implemented as a method, apparatus, or article of manufacture using standard private and/or engineering techniques. The term "article of manufacture" as used herein is intended to encompass a computer program that can be accessed from any computer readable insult, carrier or media. By way of example, computer readable media may include, but are not limited to, magnetic storage devices (eg, hard disks, floppy disks, magnetic strips, etc.), optical devices (eg, compact discs (CD), digitally versatile discs (DVD) Etc.), 126198.doc -11 - 200835361 Smart cards and flash memory devices (eg EPROM, cards, sticks, key drives, etc.). In addition, the various storage media described herein can represent one or more devices and/or other machine-readable media for storing information. The term "machine-readable medium" may include, but is not limited to, wireless channels and various other media capable of storing, containing, and/or carrying instructions and/or data. The techniques described herein are applicable to a variety of wireless communication systems, such as multiple storage. Communication systems, broadcast systems, wireless local area networks (WLANs), etc. The terms "system" and "network" are often used interchangeably. Multiple access systems may utilize, for example, code division multiple access (CDMA), Multiple access mechanisms such as time division multiple access (TDMA), frequency division multiple access (FDMA), orthogonal FDMA (OFDMA), single carrier FDMA (SC-FDMA), etc. Multiple access systems may also utilize multiple access A combination of mechanisms, such as one or more multiple access mechanisms for the downlink and one or more multiple access mechanisms for the uplink. OFDMA utilizes orthogonal frequency division multiplexing (OFDM), which is more Carrier multiplex mechanism. SC-FDMA can utilize regionalized frequency division multiplexing (LFDM), interleaved FDM (IFDM), enhanced FDM (EFDM), etc., which are collectively referred to as single carrier FDM (SC-FDM). Carrier multiplex mechanism. OFDM and SC·FDM divide the system bandwidth For multiple (K) orthogonal subcarriers, these orthogonal subcarriers may also be collectively referred to as carrier frequency modulation, bin, etc. Each subcarrier may be modulated by data. Generally speaking, Modulating the modulated symbols in the frequency domain by OFDM and transmitting the modulated symbols in the time domain by SC-FDM. The LFDM transmits data on consecutive subcarriers, and the IFDM transmits data on subcarriers distributed across the system bandwidth, and EFDM transmits data over a group of consecutive subcarriers. 0 126198.doc -12- 200835361 OFDM has certain desirable features, including the ability to combat general multipath effects in terrestrial communication systems. However, the main disadvantage of OFDM is OFDM waveforms. The higher peak-to-average power ratio (PAPR), that is, the ratio of the peak power to the mean power of the OFDM waveform can be higher. The higher PAPR is when all subcarriers are independently modulated by the data. Possible "in-phase (or coherent) additions are caused. The high PAPR of an OFDM waveform is undesirable and can degrade performance. For example, a larger peak in the OFDM waveform may cause the power amplifier to operate in a highly non-linear region or possibly to perform a clip, which in turn may cause intermodulation distortion and enable the signal. Other artifacts of quality degradation. To avoid non-linearity, the power amplifier can operate at a post-shift below the average power level of the peak power level. By operating the power amplifier after shifting from peak power (where in an example, the back shift can vary from 4 dB to 7 dB), the power amplifier can handle larger peaks in the waveform without over-distorting. SC-FDM (eg, LFDM) has certain desirable features, such as the robustness against multipath effects similar to ® OFDM. Furthermore, SC-FDM does not have a high PAPR because the modulation symbols are transmitted in the time domain by SC-FDM. ^ The PAPR of the SC-FDM waveform is determined by the signal points in the selected signal group (eg, Μι PSK, M-QAM, etc.). However, due to non-flat communication channels, time domain modulation symbols in SC-FDM are susceptible to intersymbol interference. The equalization of the received symbols can be performed to mitigate the deleterious effects of intersymbol interference. In one aspect, OFDM and SC-FDM (e.g., LFDM) can be used to transmit on a 126198.doc -13-200835361 fixed link (e.g., uplink). In general, the link efficiency of an OFDM waveform exceeds the link efficiency of an SC-FDM waveform. The higher link efficiency of OFDM is offset by the backward shift of OFDM's larger power amplifier than SC-FDM. SC-FDM therefore has a lower PAPR advantage over OFDM. For UEs with higher signal-to-noise ratio (SNR), the link-level gain of OFDM can exceed the PAPR advantage of SC-FDM. By utilizing OFDM and SC-FDM, the system can benefit from the higher link efficiency of OFDM in high SNR situations and the PAPR advantage of SC-FDM in low SNR situations. In general, any SC-FDM mechanism can be used in conjunction with OFDM. In addition, OFDM and SC-FDM can be used in combination for uplink or downlink or uplink and downlink. For the sake of clarity, most of the following description is directed to the joint use of OFDM and LFDM on the uplink. Referring now to Figure 1, a block diagram of a system 100 for providing dynamic power amplifier post shifting is illustrated. System 100 includes at least one base station 102 and at least one mobile device 104 supported by a sector of base station 102. The term sector may refer to a base station and/or a zone covered by a base station, depending on the context. For the sake of simplicity, a single base station and mobile equipment are described. However, system 100 can include multiple base stations and mobile devices. The base station 102 can explicitly control the sub-band scheduling of the mobile device 104. The sub-band scheduling achieves multi-user diversity gain by adaptively scheduling mobile devices over a limited area of the system band based on channel conditions and other factors. The subband size provides sufficient frequency diversity to prevent performance degradation of fast mobile mobile devices and degradation of sector throughput over the same level of service scheduling. The smaller sub-band can also cause the sub-band scheduling 126l98.doc •14-200835361 to be a relay efficiency _, loss (for example, the sub-band is more candidate mobile device less secret * mother 4 band optional ~) y In some cases, the scheduling of the scheduling algorithm is described as one or more sub-bands as described herein. The assignment is made w (eg, 'as assigned, such as & one can also be described in other units • τ - or a plurality of basic nodes. Temporarily turn to Figure 2, the day η 士 σ on a specific day > ι bottle--, ° /, an exemplary channel tree with local jumps. Action: Prepare internal scheduling And having a bandwidth less than the entire sub-band assigned eight degrees and hopping across the sub-band to locally maximize the channel interference /, in Figure 2 'Each basic node can be mapped to many consecutive carrier frequencies in frequency (eg 'As shown in the figure' 16). The set of eight basic nodes (four) ^ - sub-band 'This sub-band consists of 128 consecutive carrier frequency modulations. In the field " (eg, base node) can be skipped in a pseudo-random manner except for the sub-band scheduling mode In addition, the diversity mode can also be a solitary sector that can primarily serve fast moving users (e.g., sectors covering an idle highway). In such cases, the base node of the channel can jump across the entire frequency band. Referring back to Figure 1, in an example, to support sub-band scheduling, the mobile device 104 can provide feedback to the base station 102 regarding the properties of the forward link channel associated with different sub-bands. The amount of feedback can be, for example, returned Because the gain in the forward link performance of the subband schedule is balanced relative to the reverse link burden caused by the feedback channel. The appropriate tradeoff depends on the load of the reverse link control channel, which is the reverse link control channel. In addition to carrying sub-band scheduling feedback, other reverse link control information may be carried. According to one aspect of the present disclosure, mobile device 104 transmits 126198.doc •15-200835361 power limit information to base station 102. 1() 2 uses the received power limit information to schedule the mobile device m on the sub-band. The power limit information may include a larger power amplifier (pA) than the mobile device 104. Small and/or capability related information H power limit information may include different power levels that may be used for different types of assignments. For example [mobile device 104 may have one or more power levels available in the internal subband, while Having one or more disparate power levels available on the edge sub-band. The mobile device may also report at its assigned traversal, for example, the entire bandwidth, an internal sub-band, and/or a single base node. The maximum power that can be achieved. In addition, the information can convey the effects of interference constraints, if any. In addition, the power limit information can be included in a given sector or location within a cell and/or with respect to more than one sector or Location information of the community. Additionally, the power limiting information transmitted by the mobile device 104 can include carrier interference parameters experienced by the mobile device 104. Although the map! Depicting the mobile device 1 to 4 transmitting the power restriction information to the base station 102, but it should be understood that the base station 102 can infer from the link and communication with the mobile device 1 to 4, the base station 102 can Any power constraints imposed on the mobile device 1〇4 are inferred by evaluating the received power level or the received feedback. The base station 102 uses power limiting information to schedule the mobile device 1 〇 4 on the secondary frequency band available to the system 100. In accordance with one aspect of the present disclosure, base station 102 can primarily schedule power limited mobile devices on internal subbands. Mobile devices without power limitation can be scheduled on the remaining spectrum. In an example, when the base station 102 selects the sub-band, the power limit of the mobile device 1〇4 can be considered in addition to the channel selectivity across the sub-band. This 126198.doc -16- 200835361 outer base station 102 can transmit scheduling information to the mobile device 104 indicating the sub-band to be used by the mobile device 104. Referring now to Figure 3, a wireless communication system 300 in accordance with various embodiments presented herein is illustrated. System 3A includes a base station 302 that can include multiple antenna groups. For example, one antenna group can include antennas 304 and 306, another group can include antennas 308 and 310, and additional groups can include antennas 312 and 314. Two antennas are illustrated for each antenna group, however, each group may utilize more or fewer antennas. As will be appreciated by those skilled in the art, base station 302 can additionally include a transmitter chain and a receiver chain, each of which can include a plurality of components associated with signal transmission and reception (eg, a processor, Modulator, multiplex 1 §, demodulation transformer, demultiplexer, antenna, etc.). The base station 302 can be associated with one of the mobile devices 316 and the mobile device 322 or the mobile device δ. However, it should be understood that the base station 3〇2 can be substantially any number of actions similar to the mobile devices 316 and 322. Device communication. Mobile devices 316 and 322 can be, for example, cellular phones, smart phones, laptops, handheld communication devices, handheld computing devices, satellite radios, global positioning systems, PDAs, and/or for wireless communication System 300 is any other suitable device. As depicted, mobile device 316 is in communication with antennas 312 and 314, wherein antennas 312 and 314 transmit information to mobile device 316 via forward link 318 and receive information from mobile device 316 via reverse link 32. In addition, mobile device 322 is integrated with antennas 〇4 and 〇6, wherein antennas 304 and 306 transmit information to mobile device 322 via forward link 324 and receive information from the mobile device via reverse link 326. For example, in a frequency division duplex (FDD) system, the forward link 318 can utilize a different frequency band than the frequency band used by the reverse 126198.doc • 17-200835361 to the link 320, and the forward link 324 A different frequency band than that used by the reverse link 326 can be used. Additionally, in a time division duplex (TDD) system, 'the forward link 318 and the reverse link 320 can use a common frequency band' and the forward link 324 and the reverse link 326 can use a common frequency band. Each group of antennas and/or the area in which they are designated to communicate may be referred to as a sector of base station 302. For example, an antenna group can be designed to communicate with mobile devices in sectors of the area covered by base station 302. In the communication via forward links 318 and 324, the transmit antennas of base station 3〇2 can be beamformed to improve the signal to noise ratio of mobile devices 316 and 322 to links 318 and 324. Furthermore, although the base station 3〇2 utilizes beamforming to transmit to the randomly dispersed mobile devices 3丨6 and 322 via the associated coverage 'but compared to the base station transmitted to all mobile devices via a single antenna' Mobile devices in neighboring cells can experience less interference. According to an embodiment, the system 300 can be a multiple input multiple output (μίμο) communication system. In addition, system 300 can utilize any type of duplexing technique to divide communication channels (e.g., forward link, reverse link, ...), such as FDD, TDD, and the like. Turning now to Figure 4, illustrated is a wireless communication system 400 that implements secondary band scheduling based on considerations of power limitations. System 400 includes a base station 402 that communicates with mobile device 404 (and/or any number of disparate mobile devices (not shown)). The base station 402 can transmit information to the mobile device 4〇4 via the forward link channel; in addition, the base station 402 can receive information from the mobile device 404 via the reverse link channel. Additionally, system 400 can be a helium system. SiS 400 uses a mitigation technique that reduces the nonlinear distortion of the spectral mask margin. Nonlinear distortion is a phenomenon related to, for example, the nonlinear relationship between the input of an electronic device and the output of 126198.doc -18-200835361. According to one aspect, the non-linear relationship of interest is related to the power amplifier. The mobile device 404 can include a power limit indicator 41A, a back shift estimator 412, and a power amplifier 414. The power limit indicator 41 of the mobile device 404 determines a power limit indication that reflects the power constraints imposed on the mobile device 404. Mobile device 404 transmits a power limit indication to base station 4〇2. It should be understood that the base station 402 can also infer the information from its link and communication with the mobile device 4〇4. For example, base station 4〇2 can evaluate the received power level or received feedback to determine the power constraints imposed on mobile device 4〇4. The power limit indication may include information related to the power amplifier size or capability of the mobile device 4〇4. In addition, the power limit indicator 41 can deliver the effects of interference constraints, if any. In addition, power limiting information may include locations within a given sector or cell and/or information about more than one sector or cell. Additionally, power limiting information transmitted by mobile device 404 may include carrier experienced by mobile device 404. Interference parameters. Device 404 receives the power limit indication and uses the finger

The service quality (q〇s) user schedules the base station 402 to determine the sub-band schedule sub-band scheduler 408. i power limit indication and cross 126198.doc -19- 200835361 p field j frequency, on. The user of the best-effort service that is not subject to interference control at the sector or cell edge (for example, the user's transmission power is not limited by the busy bit from the neighboring sector) can also be scheduled in the spectrum configuration. Within the ^ field j frequency τ. In addition, the sub-band scheduler can schedule the unpowered mobile device on the remaining spectrum. For example, after scheduling a power-constrained user, the interference at the sector or cell edge is restricted (for example, the user's transmission power is affected by busy bits from neighboring sectors). Restricted) users of best-effort services scheduled in the spectrum

* On the right part. In addition, users with larger power amplifier sizes and users with higher carrier-to-interference (C/I) ratios can be scheduled on the configured residual frequency. A user with 鬲C/Ι can only benefit marginally from a further increase in C/I, in one example, a further increase in C/I can be caused by scheduling on the middle region of the configured spectrum. . The internal subband is a subband that is far from the edge of the spectrum configuration or total bandwidth. The out-of-band transmission is a transmission caused by the modulation process at a frequency that is immediately outside the configured bandwidth and/or at a certain distance from the configured bandwidth. * The total bandwidth traversed by the out-of-band transmission level quasi-view assignment and the proximity of this span to the edge of the spectrum configuration or the maximum bandwidth of the system. In general, the larger the assignment span (for example, wide assignment), the higher the out-of-band transmission level will be. In addition, * assignments away from the edge result in lower out-of-band transmission levels. The out-of-band transmission level can be measured as a function of the total power at 1 MHz adjacent to the channel configuration. According to an example, the total transmitted power accumulated at 1 MHz should not exceed -13 dBm. In addition, for a typical transmit power of typically 23 dBm, the spectral mask requires approximately 30 dB of attenuation in the vicinity of 1 MHz. 126198.doc -20- 200835361 Define the spectral mask margin as the difference between the allowed transmission level and the actual transmission level. The spectral mask margin Lmask can be given by: / \ \lMHz y

According to this description, Pmd can be mask limited. According to an example, Pmd should not exceed -13 dBm. ΡΓχ can represent the total transmission power. It can represent the power spectral density at the output of the power amplifier, for example, where the number Θ(7)# can represent the power in the band of the integral. For example, the number lAf(7) points can be the power at 1 MHz adjacent to the channel configuration. A positive value indicates the margin between the allowed transfer level and the actual transfer level. A negative value indicates that the allowed transmission level is exceeded. If the mobile device 404 uses a large back shift or is given a smaller assignment' then the mobile device 404 has sufficient margin in the edge subbands in both OFDMA and LFDMA systems. In the case where the mobile device 404 uses a small back shift, the 'OFDMA device experiences a negative margin for medium and large assignments' and the LFDMA user experiences a small positive margin for the medium assignment. For users scheduled on the middle or internal sub-band, the users experience a positive margin in both the OFDM system and the LFDMA system with low back shift. By scheduling the user in the middle sub-band, '0FDMA& LFDMA has sufficient spectral mask margin, even if it is shifted after 〇 dB, this indicates that both can be shifted down. Therefore, the PAPR disadvantage of OFDMA relative to LFDMA does not affect its power efficiency when the user is vacated as the edge of the transport spectrum configuration. 126198.doc -21· 200835361 The base station 402 can transmit assignment and scheduling information to the mobile device 4〇4. The mobile device 404 includes a back migration evaluator 412 to determine that the power amplifier 4U is moving backward based on the scheduling information. The back migration evaluator 412 may determine a larger back shift when the schedule information stitched by the mobile device 4〇4 is scheduled to be among the upper or larger assignments in the edge subband. This f, for this (4) financial system, can be shifted by approximately 2 dB later for the LFDMA system to maintain a class-like margin for the spectral mask. However, if the sub-band scheduler indicates that the mobile device is scheduled on the middle or inner sub-band, the back-shift evaluator 412 can determine, for example, # i to maintain a low back-shift for the spectral mask with sufficient margin. Depending on the mode, the back shift evaluator 412 can adjust the power amplifier 414 to use a lower back shift (e.g., higher transmission power) when the mobile device 4〇4 is scheduled on the internal subband. Power amplifier 414 can operate with a higher back-shift (e.g., lower transmit power) when scheduled on the edge sub-band. Also, consider the width of the assignment. For example, in an example, when only mobile devices 4〇4 are privately queried on 16 consecutive carriers (eg, one base node), the out-of-band transmissions are assigned as continuous and across the total bandwidth. The narrow part is generally low. In this case, low back shift and high transmission power can be tolerated. According to an example, the power limit indicator 410 can include and/or determine power amplifier header spatial information about the mobile device 404; in an example, the power amplifier header spatial information is about the maximum achievable transmission of the mobile device 404 And / or receive power. This information can be transmitted to the base station 4〇2 for computing, for example, power amplifier header spatial information; the power amplifier header spatial information is about the maximum achievable received power of the base station 402, which corresponds to the maximum of the mobile device 404. The transmission power can be achieved. For example, 126198.doc -22- 200835361

This is calculated for a given point or possible broadband assignment of interest for the edge of the subband, the internal subband and/or for a single base a point (e.g. > as described with reference to Figure 2). By way of example, an out-of-band report (eg, 'via a dedicated control channel') and/or an intra-band report (eg, as part of a data packet, such as during a reverse link channel assignment and/or the like) may be reported. The information is transmitted from the mobile device 4〇4 to the base station 402 periodically in its Media Access Control: (MAC) header. In the - instance, this information can be used for actual broadband assignments. In addition, the mobile device 404 can notify the static difference power header space information corresponding to the possible broadband assignments and/or points of interest as previously listed; it should be understood that this information can remain relatively static over time. At this point, the base station 4〇2 can calculate a type of broadband assignment or attention by adding the corresponding static difference power header space to the power header space of the corresponding wideband assignment of the corresponding periodic report. Point related power header space. For example, the sub-bands can be selected by the sub-band selectors 4〇6 and/or scheduled by the sub-band scheduler 408 based at least in part on this information.
