Description

200838199 IX. DESCRIPTION OF THE INVENTION: TECHNICAL FIELD OF THE INVENTION The following description relates to a large system with respect to wireless communications, and more particularly to an improved uplink pilot. This application is based on USC 119 and claims to apply for the US temporary provision of the boosted uplink pilot (b〇〇sted upuNK LOT IN W-CDMA) in W-CDMA. Patent Application Serial No. 6/886, the entire disclosure of which is incorporated herein by reference.

[Prior Art] Wireless communication systems are widely deployed to provide various types of communication. For example, voice and/or information may be provided via such lineless communication systems. A typical wireless communication system or network can provide access to two or more shared resources to multiple users. For example, these systems can be a multi-access system that can support communication with multiple users by sharing available system resources (eg, bandwidth and transmission power). Examples of the system include code division multiple access (CDMA, 备绿八#々^, %...UMA), time division multiple access (tdma) system, frequency division multiple access (fdma) system, and orthogonal Frequency division multiple access (OFDMA) system. The coherent demodulation of the breeding channel is dependent on the derivation of the phase and amplitude variations introduced by the transmission link. In general, the higher data rate on the transmission link requires: good phase and amplitude reference for good execution. This amplitude and phase reference is usually given by a pilot sequence or channel.

As an example, the data rate of sixteen (16) kilobits per second (Kb/s) transmitted over the ΜΑ link above the L ΜΑ μ μ μ μ μ μ μ μ μ μ μ (SNR) pilot, knives, if the data rate increases by 128666.doc 200838199 to eleven (11) megabits per second (Mbit/s), then the channel carrying the pilot (marked as ', The signal-to-noise ratio of the dedicated entity control channel, or DPCCH) should be approximately Ec/Nt = -2 dB. This higher SNR can be achieved by increasing the transmit power of the DpcCH at the transmitter. The current and prior versions of W-CDMA do not allow the User Equipment (UE) to autonomously change the transmission power of the pilot channel to accommodate the increased scalability of the transmitted data rate, thus resulting in inefficiencies. In the case of an even higher data rate introduced on the uplink (UL) in the expected future versions of W-CDMA and other systems, such inefficiencies may be more significant unless supported by high data rate communications. In the current practice, the up and down commands issued by the fast power controlled internal loop are based on the snr measurement of the pilot bits at the base station. Unfortunately, the current deployment of base stations in the current version of W-CDMA cannot distinguish between the following: a) * the increase in transmission power of the 2DpccH initiated by the UE (ie, due to high data rate transmission); and... Improvement of the radio link (better path loss, interference level reduction). In both scenarios, the system observes that the SNR of the pilot is increased beyond the target SNR and the command is issued. The correct behavior will be to issue a downgrade command for the base station to only improve the presence of the radio link. In addition, in the case of the field practice, when the base station issues a down command in the case of an increase in the transmission power of the DPCCH, the base station operates to effectively reduce the SNR of the high data rate transmission and thereby degrade its performance. Furthermore, in the case of current practice, the improved efficiency (eg, enhancement) of the pilot transmission power will be removed after the UE has completed transmitting the high rate packet because the UE has a low snr after having performed the bad down command. Pilot, making 128666.doc 200838199 lower data rate transmission may fail. As far as the content is concerned, it should be understood that systems and methods are needed to improve the shortcomings of existing practices. BRIEF DESCRIPTION OF THE DRAWINGS A simplified summary of one or more embodiments is presented below in order to provide a basic understanding of the embodiments. This Summary is not an extensive overview of the various embodiments, and is not intended to identify any key or decisive elements of the embodiments, or the scope of any or all embodiments. Its sole purpose is to simplify the shape

Some of the concepts of one or more embodiments are presented as a more detailed description that is presented later. Various aspects are described in connection with facilitating adaptive uplink pilot multiplexing in accordance with one or more illustrative embodiments and their respective disclosures. In various embodiments, the uplink pilots can be optimized for high speed transmission by managing the grant messages processed on the pilot channels. According to the phase, a method for facilitating the promotion of pilot efficiency is described herein. The method may include determining an uplink pilot channel resource in a base station. The method may include transmitting uplink pilot channel information to More than one collaborative wireless terminal, the data record, or multiple cooperative terminals, to facilitate uplink pilots. In an illustrative embodiment, the base is provided to be operable to communicate pilots between the cooperative wireless terminals to cause the pilot channel data to be processed by the cooperative wireless terminal as a pilot channel optimized portion. Detecting its (signal-to-noise ratio) level in an illustrative operation The base station detects the pilot bits, and the exemplary base station can monitor the pilot channels and can be beaten. In an illustrative operation, the exemplary base station operates in the selected power control mode if the slot increase in the exemplary transmission from the previous transmission is greater than the selected value of 128666.doc 200838199. In the manner described, the selected power control mode includes ignoring the SNR measurement during the next transmission interval (TTI). In another illustrative operation, where the exemplary base station knows an exemplary enhanced level of pilot signals, the exemplary base station is operable to normalize the measured pilot SNR to compensate for pilot enhancement. In an illustrative embodiment, the normalized SNR can then be used by an exemplary power control internal loop. In an illustrative operation, an exemplary base station can be compared during the enhanced time slot

The pilot gain is estimated by the received pilot SNR and the pilot SNR received during its unenhanced time. Operationally, the result of this estimation can be used to normalize the measured SNR. In another illustrative operation, an exemplary base station may disable power control for a first slot that may have wireless transmissions with enhanced pilots, which operates under the assumption that the normalized SNR has not changed since the previous time slot. By way of illustration, operationally, during one or more subsequent time slots, the illustrative base station may use the difference between successive time slots to update the estimated normalized SNR. The normalized SNR can then be used by internal loop power control. In another illustrative operation, an exemplary base station may measure power or SNR received in a control channel (e.g., Enhanced Specific Entity Control Channel (E_DpDCH) of W-CDMA). By way of illustration, operatively, if the generic base station_to the general power from the wireless terminal exists, the exemplary base station is operable to cause the pilot to be enhanced and to perform the selected power mode operation. One or more. In another exemplary operation, after the signal is detected on the control channel or the data channel by the exemplary base station of the signal, the control channel operation function can be performed 128666.doc 200838199 5=. For example, in W_CDMA, the 'control channel' may be an enhanced dedicated entity control channel (E_DPCCH), and the material channel may be an enhanced dedicated physical sports channel (E_DPDCH). The ambiguous/inferior base station of the square control channel of the child is estimated and used for internal loop power control. In this way, the estimate of the operability of the control channel (10) can be adjusted = the power of the normalized pilot, and the power control can be operated in a second-order manner using the adjusted coffee estimate. r. In another illustrative operation, an exemplary base station may disable power control every time ττ, where 使 μ μ μ 用 用 用 UE UE (UE) (eg, one or more 乍",, line terminal" can be extended by enhanced guidance.

Pilot Channel Enhancement: The systems and methods described herein aim to improve the shortcomings of existing practices to optimize pilot channel operation and reduce control due to lack of pilot channel power 128666.doc -16-200838199 High data rate transmissions have led to the emergence of futile conditions. In an illustrative embodiment, the ability to autonomously increase (reluctantly) the level of the channel carrying the pilot is provided to £11. For example, in W_CDMA, this channel is referred to as a Dedicated Entity Control Channel (DPCCH). In an illustrative operation, ue may increase the transmit power of the DPcch as a function of the transport format used by the UE on the data channel (i.e., as a function of the data rate of the beacon channel). In the way of the month, after the end of the &gt; material transfer, the UE can explain the way

The operation is performed to reduce the power of the DPCCH by an amount of enhancement to resume operation at the normal power level. In another illustrative embodiment, the level of the control channel can be increased (enhanced), such as an enhanced dedicated entity control channel in W-CDMA. In an illustrative operation, the first _E_DPCCH may be decoded, and then the modulation symbols are inverted according to the selected scheme to transform the E_DpcCH into a pilot reference. In an illustrative operation, E-DPCCH can then be combined with DPCCH to provide an improved phase and amplitude reference for demodulation of other channels, such as dpdch. . In an illustrative embodiment, fast power control can be deployed to reduce the fast change in the pilot channel SNR at the receiver due to changes in the propagation channel and interference levels. By way of illustration, the fast power control currently used on the W_(3) uplink is usually dependent on two loops: the inner loop and the way. In an illustrative operation, the internal loop may perform the following operations: - Example 7 base station (9), for example, Node B, said or other infrastructure 7G device) operatively measures the SNR of the pilot-frequency bit and Comparing the measured SNR with Sakizaki, based on this comparison, issuing a up or down command to - or a plurality of cooperative wireless terminals (eg, 128666.doc 17 200838199 eg, user equipment - UE) to maintain the quantity The measured SNR is close to the target. When the square of the β statement receives the upgrade command, it operatively increases the power of the channel by one step. By way of illustration, when the UE receives a down command from any of the cells in its active set of cooperating cells (e.g., 'cooperative base stations'), it operatively reduces the power of its channel by one step. However, in the current practice, the material and down-conversion commands issued by the internal loop of the fast power control are typically recorded at the base station for the S N R measurement of the pilot bits. The W · CD μ a base station is inoperable to distinguish the following items from each other, and the transmission power of the Qiu coffee initiated by the UE is increased because of its transmission of high data rate transmission; Good path loss, interference level is reduced, and in the current practice, in both cases, the SNR of the pilot is increased beyond the target in both cases. SNR, and the release is reduced to eight. The lack of two V gates 17 7 However, the desired behavior will be to enable the base station to issue a down command only for the situation (b). By issuing the down command in the situation (4), the base station is lowered. The SNR of the high data rate transmission and thereby degrading its performance. In addition, the transmission of the pilot transmission power will be stopped after the transmission of the high rate packet has been completed. Thus, after the execution of the bad 4 drop command, the pilot can be in Low snr causes any lower data rate pass to fail. To overcome the shortcomings of existing internal loop practices, the description herein describes a wireless communication system in which an exemplary base station operates in an illustrative manner. The pilot is measured and its position is beaten. In the descriptive operation, the point 丨4 is not detected by the base station. The pilot level is determined from the previous observation 128666.doc -18- 200838199 large ydB ' An exemplary base station operatively stores data representative of ... strong pilots. In an illustrative operation, an exemplary base station operates the power control loop with feathers::: and is operable to perform the following instructions: Or a plurality of possible frequency-increasing frequencies, and switching control to operate as described by illustrative operation in τ. In the illustrative operation, the exemplary base station can monitor the pilot channel and detect The jitter of the (signal-to-noise ratio) level is measured. In the illustrative operation, if the exemplary base station (four) branch frequency increases from the previous transmission, the slot increases by more than the selected decibel value, then the exemplary base station is at the selected power. Operation in control mode. In the following way: The selected power control mode includes ignoring the SNR measurement during the next transmission interval (4) and transmitting power control commands to one or more coffee, so that - or multiple UEs will not change their average Transmission power. An exemplary base station in which the exemplary base station knows an exemplary enhancement to the pilot_number is operable to normalize the measured pilot SNR to compensate for pilot enhancement. In an illustrative embodiment The normalized SNR may then be used by an exemplary power control internal loop. In an illustrative operation, the exemplary base station may compare the pilot SNR received during the enhanced time slot with its unenhanced The pilot SNR is estimated during the time period to estimate the pilot enhancement. Operationally, the result of this estimation can be used to normalize the measured SNR. ϋ In another illustrative operation, the exemplary base station may deactivate the pair There may be power control of the first slot of the wireless transmission of the enhanced pilot, which operates under the assumption that the normalized SNR has not changed from the previous time slot. By way of illustration, operations 128666.doc • 19-200838199 succinctly, during one or more subsequent time slots, the exemplary base station may use the difference between successive time slots to update the estimated normalized SNR. The normalized SNR can then be used by internal loop power control. In another month of operation, the exemplary base station can measure the power or snr received on the Enhanced Dedicated Entity Control Channel (E 7 PDCH). By way of illustration, operatively, if the exemplary base station detects the presence of substantial power from one or more UEs, the exemplary base station is operable to cause the pilot to be enhanced and to perform the selected power One or more of the mode operations. In another exemplary operation, after the signal is detected by the exemplary base station of the signal on the Enhanced Dedicated Entity Control Channel (E_DPCCH) or the Enhanced Dedicated Physical Data Channel (E-DPDCH), 1&gt;(:(:^ Operation Power Control. By way of illustration, the SNR of E_DPCCH can be estimated by an exemplary base station and used for internal loop power control. By way of illustration, operationally, the estimated SNR of the E-DPCCH The power may be adjusted to represent the normalized DPCCH, and the power control may be operated in an illustrative manner using the adjusted SNR estimate. In another illustrative operation, the exemplary base station may stop at the beginning of each Ding With power control, the user equipment (UE) can transmit via the enhanced pilot. The exemplary base station can operatively determine when the UE can transmit via the enhanced pilot because the exemplary base station can be used by one or more The messages are granted and controlled by the DTX control to provide control of the UE transmission. In an illustrative manner, when the exemplary base station decodes the E-DpccH, the power control can be re-enabled. In an illustrative operation E-DPCCH can be conveyed from the instantiation 128666.doc -20- 200838199 UE transmission which format - and whether the UE is using pilot enhancements in the sub-bright operation, the results of the exemplary base station can be used to make the DPCCH pilot SNR Estimating normalization. In another illustrative embodiment, an exemplary base station may disable power control in the event of an enhanced pilot. In an illustrative manner, an exemplary base station may be addressed to one or A plurality of cooperating wireless terminals communicate a grant message to monitor UE operations to enhance pilots and limit their frequency of occurrence. In an illustrative embodiment, the exemplifying 恍 扁 1 丁 基地 sheng sheng base port can be directed to one or more Wireless terminals exclusively transmit absolute grants to allow one or more wireless terminals (e.g., to utilize enhanced pilots to transmit high data rates for special claws. In another illustrative embodiment, When the UE transmits the enhanced pilot, it operatively ignores the &quot;down&quot; command from the non-servo cell. In the illustrative operation, the external loop can be executed with τ - (4): the neutral base station operation Sexual measurement comes from Or a service item f (QoS) of the received data of the plurality of cooperative wireless terminals (eg, 'block error rate (Β or bit error rate (峨))' and may be necessary, for example, to achieve the desired (10) The target SNR is adjusted as well. In an illustrative embodiment, the measurement of the SNR of the pilot can be used to derive a change in the quality of the radio link to adjust the transmission power of the channel transmitted by the UE. In the case of the Enhanced Uplink (EUL) feature, data can typically be transmitted on a channel named E-DPDCH. Operationally, the pilot reference can still be carried on the DPCCH in the manner, and pilots can be used. Multiple tests are used for coherent demodulation of E-DPDCH and other channels. The uplink in the wireless system is a resource shared by the cooperative UEs. In the manner of the description 128666.doc 21 · 200838199, an exemplary base station can maximize overall uplink performance by controlling the amount of uplink resources used by each individual UE. In an illustrative embodiment, an absolute grant message can be deployed to achieve the desired uplink resource control. By way of illustration, the absolute grant message is a message transmitted by the base station scheduler on the downlink to directly adjust the grant rate of a UE under its control. By way of illustration, the absolute grant message itself may include multiple fields that are multiplexed together and transmitted on a downlink channel under the name E-AGCH. These fields may include: Absolute Grant Value This field indicates the maximum EUL data to pilot ratio that the UE will be allowed to use for the next transmission (E- Absolute Grant Category: This field indicates the applicability of the absolute grant. (It can take two different values: "Every HARQ process" or "all HARQ processes", which can indicate whether HARQ process start/revocation will affect one or all processes.) To overcome the consequences of communication by an exemplary base station and collaboration The ambiguity of the absolute grant message sent by the wireless terminal can combine the pilot enhancement with the DPDCH and the nominal DPCCH power ratio into a new absolute message metric, wherein, by way of illustration, the nominal DPCCH power is unenhanced. The power of the DPCCH. By way of illustration, the absolute grant message metric can be calculated as follows: [(E-DPDCH power) + (enhanced DPCCH power)] / [nominal DPCCH power] -1 (equation 1) or, etc. Effectiveness: 128666.doc -22· 200838199 (Equation 2) where the nine and the feet are the amplitude gains of E-DPDCH and DPCCH, respectively, and where the amplitude ratio of the enhanced DPCCH to the nominal DPCCH is used. Linear And written in amplitude, as will be well understood by those skilled in the art, which can be derived, for example, by any other means to account for power enhancement in the metric. For example, power can be used instead. Or calculations can occur in the logarithmic domain.

In a particular embodiment where the power of the E-DPCCH is enhanced and used as an additional phase and amplitude reference, the metric can be calculated as: m = [(E-DPDCH power) + (enhanced E-DPCCH power) - (standard) Said E-DPCCH power)] / [nominal DPCCH power] (Equation 3) or, equivalently:

In an illustrative operation, the power of the channel other than the DPCCH (i.e., the power of the unenhanced DPCCH) is also affirmed if the deployment power enhancement '_ relative to the nominal DP' is operational. In an illustrative operation, the dpcch power can be arbitrarily enhanced without affecting the power of other channels transmitted by the UE. Furthermore, the power of E_DpDCH can be adjusted and specified relative to the nominal DPCCH power or relative to the enhanced DPCCH power. In an illustrative operation, data may be transmitted by fixed communication time intervals (e.g., Transmission Time Interval (TTI)) by one or more cooperating wireless terminals. Pilot Channel Optimization: Referring now to Figure 1 '' illustrates a multiple access wireless communication system in accordance with an embodiment. The base station (BS) includes a plurality of antenna groups, one including 1〇4 and 106, the other including 1〇8 and 11〇, and an additional one including 112 and 114. In Figure 1, only two antennas are shown for each antenna group, however, more or fewer antennas may be utilized for each antenna group. User equipment 116 (UE) is in communication with antennas 112 and 114, wherein antennas 112 and 114 transmit information to UE 116 on downlink 120 and receive information from UE 116 on uplink 118. UE 122 communicates with antennas 106 and 108, where lines 128666.doc -24- 200838199 lines 106 and 108 transmit information to UE 122 on downlink 126 and receive information from UE 122 on uplink 124. In an FDD system, communication links 118, 120, 124, and 126 can use different frequencies for communication. For example, the downlink 12 〇 may use a different frequency than the frequency used by the uplink U8. Each antenna group and/or the area in which it is designed to communicate is often referred to as the sector of the base station. In an illustrative embodiment, the antenna groups are each designed to communicate with the UE in a sector of the area covered by the base station 100.
