Description

200541355 IX. Description of the invention: [Technical field to which the invention belongs] The present invention generally relates to communication, and more specifically, the present invention relates to a novel and improved method and device for selecting a service sector. [Prior Art] Wireless communication systems are widely deployed to provide various types of communication such as audio and data. These systems may be based on coded multi-directional proximity (CDMA), time-division multi-directional proximity (TDMA), or some other multi-directional proximity technology. A CDMA system provides certain advantages over other types of systems, including increased system capacity.

A CDMA system can be designed to support one or more CDMA standards, such as (1) tia / eia_95_b mobile station-base station compatible standard for dual-mode wideband spread-spectrum cellular systems, (IS-95 standard), (2) A standard named by the association named "3rd Generation Partnership Project" (3GPP) and included in a group of documents including document numbers 3g TS 25.211, 3GTS 25.212, 3G TS 25.213, and 3G TS 25.214 (W-CDMA standard), (3) proposed and included by an association named, 3rd Generation Cooperative Private 2 '(3GPP2), using the TR-45.5 physical layer standard of the Kcdma2000 spread spectrum system "(IS_2OO00 standard) and (4) some other standards. Among the standards named above, such as 4, shared spectrum is available among many users at the same time, and uses such as power control and soft mode The technology of delivery can be used to fill the mouth and mouth, and to delay sensitive services such as audio. The data service can also be used more recently-some have already proposed a number of systems and systems, which use more 98232.doc 200541355 Modulation of 咼 order, carrier interference from mobile station (C / i) Very fast feedback, very fast scheduling, and scheduling for services with more relaxed latency requirements to enhance data service capacity. This is only an example of the data communication system using these technologies In order to meet the high data rate (HDR) system of D18 / 18 / 18-856 standard (18-856 standard). Compared with other standards named above, an IS_856 system uses the available data in each hive at a time. The entire spectrum is used to transmit data to a single user, where the user is selected based on link quality and other considerations such as data waiting. In this case, the system spends a greater percentage of time when the channel is good To send data at a higher rate, and thereby avoid limiting resources to support inefficient rate transmissions. The net effect is higher data capacity, higher peak data rate, and higher average throughput. The system can incorporate -2000 supports delay-sensitive data for audio channels or data channels as well as support for packet data services such as those described in the IS-8586 standard. Such a system is described in a proposal under Θ: a proposal entitled "Updated Joint Physical Layer Proposal for lxEV-DV," submitted to 3GPP2 on June 11, 2001 under document number C50-20010611-009; 2001 The proposal of "Results of L3NQS Simulation Study," which was submitted to 3GPP2 with document number C50-20010820-011 on August 20; and "System Simulation" which was given to 3GPP2 by the parent of document C50-20010820_012k on August 20, 2001

Results for the L3NQS Framework Proposal for cdma2000 lxEV-DV, ". These and subsequent related documents (such as Γ revision C of the IS-2000 standard, including C.S0001.C to C.S0006.C and 98232 .doc 200541355

C.S0001.D to C.S0006.D) are hereinafter referred to as lxEV-DV. lxEV-DV A system (such as the system described in the lxEV-DV standard) usually includes four types of channels: · Overhead channel, dynamically changing IS-95 and IS-2000 channels, and a forward packet data channel (F-PDCH) and some spare channels. These additional signal channel assignments change slowly and can remain unchanged for several months. It generally changes only when there are major network configuration changes. These dynamically changing IS-95 and IS-2000 channels are assigned on a per call basis or they are used by IS-95 or IS-2000 to release 0 to B packet services. Normally, the F-PDCH is allocated to the F-PDCH for the remaining data services after the available signal channels and dynamically changing channels have been assigned. The F_PDCH can be used for data services that are less sensitive to delay, and the IS_2000 channels are used for services that are more sensitive to delay. Use F-PDCH (similar to the communication channel in the IS-856 standard) to send data to one user in each hive at a time at the highest supported data rate. In IS-856, when transmitting data to a mobile station, the entire power of the base station and the entire space of the Walsh function are available. However, in the proposed lxEV-DV system, some base station power and some Walsh functions are configured to add signal channels and existing IS-95 and cdma2000 services. The supported data rate mainly depends on the power used to add the signal channel, IS-95 channel and IS-2000 channel, and the available power and Walsh code after the Walsh code is assigned. One or more Walsh codes are used to spread the data transmitted via F-PDCH. In the lxEV-DV system, although many users may be serving 98232.doc 200541355 in a honeycomb, the base station—usually through the sink—transmits to the 11 port. (The hunter can schedule transmission for two or more users and configure two y and / or sh channels appropriately for each user to transmit to two or two users.) Based on some kind of scheduling The program algorithm selects the mobile station for forward link transmission. You, in this system, impress the station self-service base station to receive the forward key connection data. As described in 2, the reverse link feedback from a mobile station to the service station can be scheduled and transmitted to the link. A mobile station will not receive forward packet data through mPDCHn from more than one base station — the mobile station passes through, and the link can be in a soft parent transfer with — or multiple non-serving base stations and / or sectors to provide a reverse link Knot switching diversity. In the CDMA2000 system derived from Rev. C, there is a forward link and a spearhead, and the channel quality feedback of the mobile station. For example, in the second middle school, the mobile station estimates the quality of the forward link and calculates the expected transmission rate to maintain the transmission rate. All requests from each mobile station are transmitted to that base station. The scheduling algorithm may, for example, select a mobile station for transmissions that can support relatively two transmission rates in order to more fully utilize the shared communication channel. As another example, in the XEV-DV system: the mother-mobile station transmits 1 wave of interference material as the channel product through the reverse channel quality indicator channel or R.CQICH. Reliance schedule: the mobile station selected for transmission by the different method, and the appropriate speed and transfer format according to the channel product. Various scheduling algorithms can be constructed, such as the proportional fairness algorithm detailed in US Patent No. 6,229,795. 98232.doc 200541355 (FL) Packet Data Channel (F-PDCH) and an associated Packet Data Control Channel (F-PDCCH). The mobile station (MS) only reports the C / I of the current BS sector and selects the F-PDCH and F based on the quality of the forward link channel of each base station (measured as FL C / I). -The best forward link base station (BS) sector of the PDCCH. The mobile station (MS) is switched to another base station according to the conversion procedure described in the media access control (MAC) standard.

And sector load information to autonomously determine a new / best serving sector. Exemplary Communication System FIG. 1 is a diagram of a wireless communication system 100 that can be designed to support one or more CDMA standards and / or designs (eg, W_CDMA standard, IS-95 standard, cdma2000 standard, HDR specifications , LxEV_Dv standard). In an alternative embodiment, the system 100 may also deploy any wireless standard or design other than the 7 (: 1)] ^ 8 system. For simplicity, the system 100 is shown as including three base stations 104 in communication with two mobile stations 106. This base station and its coverage area are often collectively referred to as a "honeycomb". In the IS-95 system, a hive can contain one or more 98232.doc -14- 200541355 sectors. In the W_CDMA specification, each sector of the base station and the coverage area of the sector are called a honeycomb. Depending on the system being constructed, the mother-mobile station 106 can communicate with the two (or may be) base stations 104 via the forward link at any given moment, and it can be seen whether the mobile station is in power The parent hand communicates with one or more base stations via the reverse link. The forward link (ie, the downlink) refers to the communication k from the base station to the mobile station, and the reverse link (ie, the uplink) refers to the communication from the mobile station to the base station. As described above, the wireless communication system 100 can support simultaneous users (such as the IS_95 system, and occasionally allocate the entire communication resource to a user (such as the IS_856 system), or can share the communication The resource is to allow two types of access. The lxEV_DV system is an example of a system that can divide the communication resource between the two types of access and dynamically configure the allocation according to user requirements. In lxEV- In the DV system, although many users may be using packet services in a hive, the base station is usually transmitted to the _impulse station via F-PDCm. (By scheduling transmission for two or more users and The power and / or Walsh channels are appropriately configured for each user to transmit to two or more users.) Based on a scheduling algorithm, a mobile station is selected for forward link transmission. On-similar to IS- In the 856 or lxEV-DV system, the scheduling is based in part on channel quality feedback from the mobile station serving the party. For example, in IS-856, the mobile station estimates the quality of the forward link and Calculate the expected transmission rate that can be maintained for the field condition. 纟 Since each mobile station's place 98232.doc -15- 200541355, the required rate is transmitted to the base a Toyakou. The scheduling algorithm can For example) In order to support transmission at a relatively high transmission rate, select a mobile station in order to make fuller use of the shared communication channel. As another example, every -7 τ is only an example, in the lxEV-DV system Each subscription port is instructed by the reverse channel quality channel or transmitted by a carrier to estimate the material quality & quality estimation. The scheduling algorithm is used to determine the mobile station selected for transmission and the appropriateness according to the channel quality Rates and transmission formats. Exemplary channels A typical data communication system may include various types of channels or channels. More specifically, 'commonly deploy one or more data channels. Although in-band control signal transmission Can be included on a data channel, but it is also common to deploy one or more control channels. For example, in a 1xEv_dv system, forward packet data is defined for control and data transmission through the forward link respectively The control channel (F-PDCCH) and the forward packet data channel (f_pdch). The forward packet data channel (F-PDCH) is a shared packet resource channel that can support high-speed operation traffic. It is processed by the MAC layer scheduling to the Channel access. This channel is different from all other channels due to adaptive modulation and coding. Also, it uses a variable Walsh code space. This means that when guided by the MAC layer based on feedback information from the mobile station The modulation and coding can be changed between frames. The feedback information is included in R-CQICH (the ratio of the pilot chip energy Ec to the total noise density price of the strongest F-PICH received in its report ^ / milk) During R-ACKCH, the R-ACKCH indicates whether the frame is successfully received. The chosen modulation and coding also depends on the available WalsIuf. Unlike all other channels, F-PDCH uses only the remaining resources at the base station. This 98232.doc -16-200541355 means that the power consumed by the F-PDCH and the Walsh code can be changed from frame to frame. The forward packet data control channel (F-PDCCH) is a shared channel, which is mainly used to transfer information about the F-PDCH transmission format. Layer 2 control information transmitted in parallel via the F-PDCCH is accompanied by data transmission via the F-PDCH. The control information channel allows correct demodulation and decoding of the associated F-PDCH frame. 0 The reverse channel quality indicator channel (R-CQICH) is a support channel, which is used for adaptive coding and modulation via F-PDCH. . This channel is used to transfer F-PICH Ec / Nt to the serving base station. This information is used to select the appropriate modulation and coding mechanism. Further, one mobile station selected for transmission via F-PDCH or, in some cases, two mobile stations may be selected based on a predetermined fairness metric and r_CqICH value. The information transmitted through the channel can be a full 4-bit coded value of F-PICH Ec / Nt, or an up / down indication relative to one of the previously accumulated values. The R-CQICH is also used to indicate the base station corresponding to the reported f_PIch Ec / Nt. The R-gQICH Walsh Cover * index identifies each base station. FIG. 2 depicts an exemplary mobile station 106 and a base station 104 configured in a system suitable for data communication. Base station 104 and mobile station 106 are shown as communicating via a forward link and a reverse link. The mobile station 106 receives the forward link signal in the receiving subsystem 220. A base station 104 that can communicate with this forward data and control channel (detailed below) may be referred to herein as a service station for mobile station 106. An exemplary receiving subsystem is described in further detail below with reference to FIG. Carrier interference (C / I) estimation is performed in the mobile station 106 for the W-directional link signal received from the serving base station at 98232.doc 200541355. A C / I measurement is an example of a channel quality metric used as a channel estimate, and alternative channel quality metrics may be deployed in alternative embodiments. This C / I measurement is passed to the transmission subsystem 210 in the base station 104, an example of which will be further detailed below with reference to FIG. The transmission subsystem 210 passes the c / i estimate via a reverse link, where it is passed to the serving base station. Note: In a soft handover scenario, the reverse link signal transmitted from a mobile station can be received by one or more base stations other than the serving base station (referred to herein as a non-serving base station). The receiving subsystem 230 in the base station 104 receives C / I information from the mobile station 106. The scheduling software 24o in the base station 104 is used to determine whether and how data should be transmitted to one or more mobile stations within the coverage area of the serving cell. Any type of scheduling algorithm can be deployed within the scope of the present invention. The application was filed on February 11, 1997 and in 2002! month! Awarded to Zhan "Zhan et al.

An example is disclosed in U.S. Patent No. 6,335,922, entitled "METHOD AND APPARATUS FOR FORR UNK RATE SCHEDULING," which is assigned to the assignee of the present invention. On the first day of the day, J instability lxt V_ W Η π is received by 轫 谷 ^ Measurement indication can-determine the rate of transmission of certain data, the mobile station is selected for forward key transmission. Select based on system capacity—Target mobile station DEK—Directly share the resources at its maximum supported rate: Profitable. Therefore, the typical target mobile station selected may be the mobile station with the largest reported c / ι. Other factors can also be incorporated into scheduling decisions. For example, a minimum service product and warranty may have been made to various users. 98232.doc -18- 200541355 2 Can be a-relatively low reported mobile station ^ Optional for transmission for maintenance-minimum data transfer Rate to a certain user ^ > = In the illustrative system, she schedules the transmission to which it is scheduled — σσ, and also determines a transmission

In the embodiment of daily rate, modulation format, and power, for example, such as a CD system, the decision of the rate / modulation format at the mobile station is based on the channel quality measured at the mobile station. The transmission format can be transmitted to the serving base station instead of C / I measurement. Those skilled in the art will recognize that there are countless combinations of supported rates, modulation formats, power levels, and the like that can be deployed within the framework of the present invention. In addition, as described herein, the scheduling tasks in this embodiment are performed in the base station, but in alternative embodiments, some or all of the scheduling process may occur in the mobile station. The scheduling software 240 directs the transmission subsystem 27 to use the selected rate and modulation. The formula X force level and the like are transmitted to the selected stage via a forward link. In the exemplary embodiment, the information on the channel (or F_pDcCH) is transmitted along with the data on the shell channel (or F-PDCH). The control dagger can be used to identify the receiving mobile station of the data on F_PDCH, as well as other communication parameters that are useful during the communication session. When F-PDCH indicates a certain mobile port as the target of radio transmission, this mobile station Should receive and demodulate the data from the bPDCCH. After receiving this data, the mobile station responds on the reverse key, 纟 α with a message indicating the success or failure of the transmission. This is generally deployed in data communication systems Retransmission technology is well-known in this technology. A mobile station can communicate with more than one base station (a situation is the well-known 98232.doc -19- 200541355 soft handover). Soft handover can include from-base station (or- Base Transceiver Subsystem (BTS)) with multiple areas (known as softer delivery) and light from multiple BTSs. Base station sectors that are delivered in soft delivery are stored in an efficient set of mobile stations. In a simultaneous shared communication resource system (such as the corresponding part of the IS-95 'IS-2_ or a lxEV_DV system), the mobile station can combine forward link signals transmitted from all sectors in the active set. One In a data system (such as the corresponding part of the IS_856 or a lxEV_Dv system), a mobile station receives a forward link data signal from a base station in the active set, where the serving base station (as described in C.S0002 according to The mobile station selection algorithm in the .C standard is determined.) Other forward link signals can also be received from non-serving base stations (examples of which will be further detailed below). Multiple base stations can be received from the base station. The reverse link signal of the mobile station, and usually the base station of the effective concentration, maintains the quality of the reverse link. It can combine the reverse link signals received at multiple base stations. Generally speaking, the The soft combining of the reverse link signals of the deployed base stations may require significant network communication bandwidth with a small delay, and therefore it cannot be supported by the exemplary systems listed above. In softer delivery , The reverse link signal received at multiple sectors combined in a single BTS can be picked up before network signal transmission is not needed. In the exemplary system described above, the Link power control maintains quality such that reverse link frames can be successfully decoded at a BTS (Handover Diversity). Exemplary Wireless Communication Device FIG. 3 is a wireless communication device such as mobile station 106 or base station 104 A block diagram of 98232.doc -20- 200541355. The blocks described in this exemplary embodiment will generally be a component of a component that is included in the base station 104 or the mobile station 106. The person skilled in the art will not Difficult to adapt the embodiment shown in Figure 3 for any number of base station configurations. The Q s line signal is received at the antenna 310 and passed to the receiver 32. The receiver 320 is based on-or multiple wireless System standards (such as those listed above) perform processing. The receiver 32 performs various processes such as radio frequency (rf) conversion, amplification, analog to digital conversion, chirping, and the like. 2. The various technologies received are well known to me in this technology. When the receiver 320 is a mobile station or a base station, respectively, 'the device can be used to measure the channel quality of the forward or reverse link, but for the sake of clarity, an independent channel quality estimator 335 (detailed (Described below). The signal from the receiver 320 is demodulated in a demodulator 325 according to one or more communication standards. In an exemplary embodiment, a demodulator capable of demodulating IxEV-DV signals is deployed. In alternative embodiments, alternative standards' may be supported and several embodiments may support multiple communication formats. The demodulator 325 can perform RAKE reception, equalization, combining, deinterleaving, decoding, and various other functions as required by the format of the received signal. Various demodulation techniques are well known in this technology. In base station ⑽, the demodulator will perform demodulation based on the reverse link. In mobile station 解调, the demodulator will perform demodulation based on the forward link. Both the data and control channels described herein are examples of channels that can be received and demodulated in receiver 320 and demodulator 325. The demodulation of the forward data channel will occur according to the signal transmission on the control channel, as described above. 98232.doc 200541355 The message decoder 33 receives the hard-to-find seven blows 2 2 & sigh, ，, work out the depleted materials and extracts them through the forward or reverse chain, Ό respectively. Signal or message leading to mobile iQ6 or base station. Message decoding: Decoding is used to set up, maintain, and disconnect calls on a system (including tone sfL or data sessions). The messages may include channel quality indicators such as C " measurements, power control messages, or control channel messages used to demodulate forward data channels. Various other message types are already familiar to me in this technology and can be found in the various communication standards supported. These messages are passed to the processor 350 for subsequent processing. Some or all of the functions of the message decoder 33 may be performed in the processor 3 50, although a discrete block is shown for clarity of discussion. Alternatively, the demodulation gain 325 can decode some information and send it directly to the processor 350 (examples are single bit messages such as ACK / NAK or power control up / down commands). The channel quality estimator 335 is connected to the receiver 320 and the channel pin estimator 3 3 5 is used for various power level estimations for the procedures described herein: and for use in communications such as Demodulation) and various other processes. In the mobile station 106, C / I measurement can be performed. In addition, the measurement of any signal or channel used in the system can be measured in the channel quality estimator 3 35 of a given embodiment. In the base station 104 or the mobile station 106, a signal strength estimation such as the received pilot power can be performed. The channel quality estimator 335 is shown as a discrete square for clarity of discussion only. It is common to incorporate this block into another block such as the receiver 320 or the demodulator 325. Depending on which signal or system type is being estimated, various types of signal strength estimates can be made. In general, within the scope of the present invention, 98232.doc -22-200541355, any type of channel quality metric estimation block can be deployed instead of the channel quality estimator 335. In the base station 104, these channel quality estimates are passed to the processing unit 35 (Π × for scheduling or determining the quality of the reverse link, as described in the next step. The channel quality estimation can be used to determine whether it is necessary to Or issue a power control command to drive forward or reverse link power to the desired setpoint. As described above, 'the external setpoint power control machine can be used to determine the desired setpoint. The signal is transmitted via the antenna 310.

The message generator 360 can be used to prepare various types of messages, as described herein. For example, the Generates c / i messages transmitted through a reverse link in a mobile station. Various types of control messages can be generated in base station 1 () 4 or mobile station ⑽ for transmission via forward or reverse link, respectively. 98232.doc -23- 200541355 The data received and demodulated in the demodulator 325 can be passed to the processor 350 for audio or data communication and to various bean components.

A link. The I processor MO may be a general-purpose microprocessor, a digital signal processor (DSP), or a special-purpose processor. The processor 35 may perform some or all of the functions of the receiver 32, the demodulator 325, the message decoder 33, the channel quality estimator 335, the message generator 360, the modulator 365, or the transmitter 37. And any other processing required by the wireless communication device. The processor 350 can be connected to dedicated hardware to assist in these tasks (details not shown). Data or audio applications can be performed externally, such as an externally connected laptop or connected to a network, on an additional processor (not shown) within the wireless communication device 104 or 106, or on an external processor The processor 350 itself. The processor 350 is connected to a memory 355, which can be used to store data and to execute instructions of various tasks and methods described herein. Those skilled in the art should understand · The memory 355 may include one or more memory components of various types, which may be wholly or partially embedded in the processor 350. As described above, in data systems such as IxEV-DV, the base stations need to be (Cut-change diversity) Decode the reverse link 98232.doc -24-200541355 with a high probability in at least one of them and minimize the interference to all reverse link base stations. In addition, in service The base station needs reliable reception of the R-CQICH. The R-CQICH provides the BTS with fast forward link channel condition updates to effectively operate the F-PDCH. Figure 4 depicts a 41A1 used to control the current serving sector and the Yu Kong An exemplary embodiment of a system of the non-serving sectors 410A2, 410B1, B2, and 41 ° C2. The mobile station 106 receives a forward link power control flow from each active set base station 104A_1104c, F-CPcCH In this example, each base station 104A-104C, BS1_BS3 contains three sectors (sectors 丨 _3), respectively, which are labeled as 410A1-410C3. In this example, the active set includes a fan Zones 410A1-2, 410B1-2, and 410C2. This is an example of a so-called soft-softer handover because the mobile station has multiple base stations (soft) and one or more sectors in the mouth ( Softer) in handover. Mobile station ^ is provided with reverse link power control feedback from each active set sector. R-CQICH is directed from mobile station 106 to the serving sector. Service sector selection Forward packet data channel operation and PDCH make it possible to effectively use BS resources for delay-allowed traffic. It =: use the channel 'and can delay the jitter to fully utilize the short-term radio channel changes due to attenuation = 2 V. By clever Scheduling, declining the efficiency of the interface. For multi-use, go to 隹 干 又 ％ ％%% knife set. In a point-to-multipoint link, such as a point-to-multipoint link that exists in a single transmission, between the rooms in a given hive, radio The channels change independently. Then the BS can choose to allocate its resources to MSs that experience the best radio propagation environment among all mobile stations in the hive and therefore maximize the production capacity. Choose among a group of mobile stations An MS is generally called multi-user diversity. In addition, 'if there is no fair constraint imposed on the BS scheduling software, the BS can schedule the MS that can support the highest data rate, and some MSs may not No information was received. A scheduling algorithm can be used, which makes multi-user diversity effects possible, meets certain fairness criteria, and minimizes changes in physical layer production. The schedule interval corresponds to a single frame, which can be 1.25 ms, 2.5 ms, or 5 ms. Self-channel quality information and available BS resources to determine the data rate. When the MS has been scheduled via F-PDCH, the forward link control channel notifies the MS. The entity that controls F-PDCH operation is called PDCH Control Function (PDCHCF). This entity controls link adaptation, scheduling, and H-ARQ Type II operations, and it is responsible for mapping f-pdch logical channels to corresponding physical channels. PDCHCF is considered as part of the MAC layer and can be constructed at the BTS. Control signal transmission F-PDCH is a shared channel on which the BS grants access for up to 5 ms. This fast access requires a fast signal transmission protocol to warn the MS. The BS uses F-PDCCH, which operates in parallel with F-PDCH. The F-PDCCH frame length is usually equal to the F-PDCH frame length. The MS buffers the signals received on the F-PDCCH and F-PDCH. Consider all three possible frame lengths of 1.25, 2.5, and 5 ms to decode the F-PDCCH. Standard F-PDCCH control message FIG. 5 is a standard F-PDCCH control message containing 21 bits. In addition, 98232.doc -26-200541355 has 16 bits for CR C and 8 encoding tail bits. In the control message itself, the first 8 bits are reserved for the MAC_ID ', which identifies the MS. The BS usually sets the MAC identifier (MAC_ID) field that specifies a MAC identifier to the MAC identifier assigned to the MS, where the MS will pair the F-PDCH with the transmission of this message via the F-PDCH Sub-packet transmissions are decoded. The range of MAC_ID is each CDMA channel or pilot. When the MS performs handover with another pilot, the MAC_ID may change. The MAC_ID is initially communicated with the MS via an Extended Channel Assignment Message (EC AM), and can then be updated by sending a Universal Delivery Indication Message (UHDM) in the event of a soft delivery event. The WALSH_MASK field specifies the Walsh space mask bitmap. The BS usually sets this block as the Walsh space mask bitmap so that when decoding the F-PDCH, it can indicate that the MS will omit certain entities in the packet data channel Walsh set. The BS usually sets each bit in this field to 0, or 1, to indicate that the MS will include Γ 'and omit (' Γ) the corresponding index in the Walsh Index Table (WCI). The EP_SIZE field specifies the encoder packet size. There are six different values that the encoder packet size can take. The MS needs to know the encoder packet size in order to successfully decode the incoming packet. The encoder packet size is included in the 3-bit EP_SIZE field. EP_SIZE-111 refers to the extended message type for F-PDCCH control information. If this message contains an extended message, the 83 usually sets this block to otherwise. For F-PDCH sub-packet transmissions that are concurrent with the transmission of this message via F_PDCH, the BS usually sets this field to the Encoding value of the encoder packet size (not '111 f). Control 98232.doc -27- 200541355 The F-PDCCH message contains only MAC-ID, EP-SIZE = 111 and 10-bit control information. The MS can simultaneously receive four parallel physical layer data streams transmitted over four independent ARQ channels. To distinguish between these channels, the F_PDCCH message contains a 2-bit field called the ARQ channel identifier (ACID). Each ACID supports independent AR-ARQ Type II operation. For F-PDCH sub-packet transmissions concurrent with the transmission of this message via F-PDCH, the BS usually sets the ARQ channel identifier (ACID) block as the ARQ channel identifier. For F-PDCH sub-packet transmission concurrent with the transmission of this message via F-PDCH, the BS usually sets the sub-packet identifier (SPID) field as the sub-packet identifier. For F-PDCH sub-packet transmission simultaneously with the transmission of this message via F-PDCH, the BS usually sets the ARQ identifier sequence number (AI_SN) field as the ARQ identifier sequence number. Because the sequence is not mandatory and repeatable with SPID = 00, the MS must be notified when a new encoder packet begins. The ARQ identifier sequence number (AI_SN) bit is added to the F-PDCCH message. Whenever a new encoder packet transmission starts, the AI_SN bit is toggled. Finally, the F-PDCCH message contains a final Walsh code index (LWCI) that can identify the last Walsh code in the Walsh code tree. Only 28 Walsh codes of length 32 are potentially available for F-PDCH. It is these 28 codes that are available to be transmitted to MS via WALSH_TABLE-ID. The scope of WALSH_TABLE_ID is each pilot. It is a 3-bit field and is part of both ECAM and UHDM. Due to, for example, F-SCH assignment and cut-off, the Walsh code space becomes fragmented_. Because the LWCI indicates the 9898.doc -28- 200541355 postcode in an adjacent Walsh code space, the F-PDCCH message (shown in Figure 5) cannot address the segmented Walsh space. For F-PDCH sub-packet transmission concurrent with transmission of this message via F-PDCH, the BS usually sets the last Walsh code index (LWCI) field to the last Walsh code index. If this message is transmitted via the F-PDCCH0 physical channel, the BS usually sets this block to indicate that the Walsh code set includes the 0th to LWCI entities in the WCI table. Otherwise, if the message is transmitted via the F-PDCCH1 physical channel, the BS usually sets this field to indicate that the Walsh code set includes (lwci0 + 1) th to LWCI entities in the WCI table. If in the F-PDCCH0 message transmitted at the same time as ^^ < 3 "〇 is greater than or equal to 01000000 ', ^ (^ is?-? 〇 (:: the last Walsh code index in the 110 message. If the MACJD in the F-PDCCH0 message is less than 01000000, then lwciO is 1. In order to alleviate the Walsh segmentation problem, a special F-PDCCH broadcast message is designed to use the signal to transmit the segmented Walsh code space available for F-PDCH. Set the MAC jD in this message to 00000000, which indicates that the message is addressed to all mobile stations in the hive. The last two Walsh codes with a length of 32 are transmitted by LWCI (the length without bit mapping is 16 (Walsh code derivatives). BS usually sets the extended message type identifier (EXT-MSG-TYPE) field to 0, 0, or 0 Γ. The BS can set this block to f〇〇f To indicate that the MS will exit the PDCH control maintenance mode. The BS can set this field to '〇1' to indicate that the MS will switch between the maximum number of frames (REV_NUM_SOFT_SWITCH_FRAMESS or REV_NUM (SOFTER-SWITCH-FRAMES) before terminating the current switching transmission mode. 98232.d oc -29- 200541355 The BS usually sets the RESERVED field of the reserved bit to '00000000. This standard allows two F-PDCHs to operate simultaneously; meaning that up to two mobile stations can be scheduled at the same time. Add this flexibility To more effectively support WAP traffic and layer 3 signal transmission. Link adaptation The F-PDCH allows adaptive modulation and coding to improve spectral efficiency. The reverse channel quality indicator channel (R-CQICH) is used to link the radio channel at the MS State information communication is communicated to the BS. This feedback channel allows the BS to construct a scheduling software that can fully utilize channel variability to achieve multi-user diversity gain. It also allows the optimal F to be selected given the current channel conditions -PDCH data rate. Channel quality feedback MS reports its channel quality via R_CQICH. There are two modes allowed: full and differential carrier interference (C / I) report. The full C / I report is better than the differential C / I report More accurate, but it will generate more reverse link costs. This complete C / I report indicates the ratio of the pilot chip energy to the total noise plus interference that is mapped to the 4-bit channel quality indicator. The pilot Ec / N Result of measurement of t. In this full mode, the current pilot Ec / Nt is reported every PCG or 1.25 ms. The difference update is interpreted as a 0.5 dB correction from the most recently accumulated C / I value. The difference mechanism It itself consists of a complete report every 20 ms and updates of 15 ± 0.5 dB in between. The accumulator sums these difference updates every PCG and refreshes itself every 20 ms when the full report is received. 98232.doc -30- 200541355 15 differences are reported after a full report. This complete report can be repeated for improved reliability. In this case, the receiver softly combines the repeated symbols. The BS can use REV_CQICH_REP; M bit, report! 5 points ECAM, UHDM, and rate change message (RATCHGM) to configure the number of times to repeat the complete C / I report. Because R-CQICH needs to be coded by the serving BS, R-CQICH symbols are repeated and soft-combined to improve reliability. The improved detection is obtained at the cost of reducing the R-CQICH symbol rate. Honeycomb Selection and Switching The MS indicates the serving BS by using one of the six different Walsh functions of the chip of length 8 to conceal the '% R-CQICH symbol. In the case of R-CQICH operation, these Walsh functions are called Walsh covert. Each R-CQICH transmission is steered (by a different Walsh concealment) to a special pilot, where the MS wishes to receive packet data channel transmission from the pilot. The MS determines the pilots from the effective set of the packet data channel to where R-CQICH transmission will occur based on the relative received strength of the pilots from the effective set of the packet data channel. At the call setup, via ECAM (or when the active set is updated via a UHDM), the network uses the REV_CQICH_COVER field to transmit the PILOT_PN signal to the Walsh covert map. The MS expects to be served by the BS associated with the Walsh covert used in reporting the C / I. Usually, the MS achieves selective diversity by selecting the BS with the strongest received pilot signal (Ec / Nt). However, because hive switching requires queue synchronization for uncompleted data, the MS cannot immediately change the serving BS. When the MS determines that the Bs pilot of the service needs to be changed, the MS calls 98232.doc -31 · 200541355 one sector / honeycomb switching procedure. To initiate the handover, the MS transmits a distinctive handover mode via R-CQICH, which indicates to the serving BS that any outstanding encoder packet (EP) transmission should be completed, and once the transmission is completed, the MS will Should switch to the target BS. During the handover period, these R-CQICH transmissions are modified to use the Walsh concealment of the target pilot in which the packet data channel is effectively concentrated. The length of the switching period depends on whether the source pilot and the target pilot (in the packet data channel active set (AS)) are in the same BTS or in different honeycombs. The time interval of these switching cycles is specified by two parameters-NUM_SOFTER_SWITCHING_FRAMES and NUM_SOFT_S WITCHING JFRAMES (included in ECAM or UHDM). The parameter NUM_SOFTER_SWITCHING_FRAMES configures the switching procedure in MS, and the switching delay PDCH_SOFTER_SWITCHING_ DELAY (or PDC_SOFT_SWITCHINGJDELAY) only informs the MS of possible interruptions in service due to switching and problems caused by problems such as queue synchronization Network delay. Optimized service sector selection mechanism In order to provide an improved service selection mechanism, at least two options can be provided. According to the first option, each sector may broadcast its own load value. However, according to this option, the MS must cause the currently serving sector to collect load information from another sector, during which it will not receive data from the currently serving sector. Because the broadcast must operate on a predetermined schedule, this will reduce the TDM gain of the shared F-PDCH. According to the second option, the load information of all adjacent sectors can be passed by the serving sector. Although this will result in multiple redundant transmissions of the same information in many sectors; however, this can be obtained by the fact that the BS freely schedules the transmission of the message to protect the capacity of FL in one party 98232.doc -32- 200541355 Compensation. And 'does not require L3 signal transmission to disable / enable this feature. bS can choose to send or not send the load information broadcast message only as needed. Referring again to FIG. 4, in one aspect, a system is provided, which includes a plurality of BS104A-C, each of which includes a plurality of sectors 41〇A1-41〇C3; and a current serving sector 410A1 Service MS 106. Each sector may have a plurality of adjacent sectors. Note ... In these exemplary embodiments, service and non-service terms are used for clarity purposes only. The disclosed technology is applicable to any collection of base stations, whether they are serving base stations or non-serving base stations. These embodiments may be described "primarily, instead of" serving "and" other, "or" second "base station instead of" non-serving, "and the principles disclosed will be applied with equal force. Each BS 104 Determine the sector load information and transmit the sector load information. The MS 106 measures the carrier-to-interference (c / i) ratio of each sector in the MS 106's active set (AS) and stores the effective set of Ms 106 ( AS) for these sectors in the carrier-to-interference (C / J) ratio measurement and based on the carrier-to-interference (C / I) ratio measurement and load information for each of the eight § sectors from the master Determine New or Best Serving Sector In this embodiment, the current serving sector will transmit the sector load information for all adjacent sectors to Ms 106. Alternatively, each sector may transmit a sector corresponding to its sector The load value of the zone load information. The BS 104 can use a dedicated channel (such as a link channel before transmitting to a single channel) to transmit round sector load information. In a construction, the dedicated channel is -Forward Packet Data Channel (F_pDCH) or-Forward Packet Data Control Channel (F-PDCCH). -During construction, the dedicated channel used to carry the sector negative 98232.doc -33- 200541355 with §fl is a forward basic channel (F_FCH) or a forward dedicated control channel (F-DCCH). In an embodiment, the BSs 104 use a common channel to multicast the sector load information. The common channel may be, for example, a forward link channel transmitted to all MSs 106 served by the sector. In the construction, the shared channel includes a forward packet data channel (F-PDCH), in which a single F-pDCH message carries the load information of more than one sector. In another construction, it is used to carry the load information of the sector. The channel is a shared forward basic channel, a shared forward dedicated control channel, a shared forward supplementary channel, a paging channel (PCH), a forward broadcast control channel (F_BCCH), or a forward universal control channel ( F-CCCH). In another conventional example, the sector load information includes, for example, a load information broadcast message that is sent to all sectors served by the sector via F-PDCH or F-PDCCH. For broadcast In terms of method, F_pDccH (preferred F-PDCCH1) sends a new message. However, it should be understood that other suitable formats may also be used, in particular, there may be several defined formats, in which a single P-PDCCH message may be carried for more than one fan Figure 6 shows the modified F-PDCCH control message according to one aspect of the present invention. The modified control message is used to transfer the sector load information. In ~, the sample can use a new Message type, where the message lists the PN_OFFSET value and the corresponding load value information. In the embodiment, the sector load information includes a load information message, and the load information message includes a PN-OFFSET block (which Including ρΝ ορρςρτ〆 吉, β DJPM PM_OFFSET value) and _ pN_L〇AD 櫊 98232.doc 200541355 bits (which includes the corresponding load value information). In a construction, the PN_OFFSET field specifies a pilot PN offset, and the PN_LOAD block specifies a sector load parameter. In the case when the load information is transmitted to a special user in a dedicated manner, the PN_OFFSET field may be replaced by a Walsh concealment index corresponding to that PN_0FFSET. Because the Walsh concealment index is usually a 3-bit value, and the PN_OFFSET is usually a 9-bit value, this reduces the required message length. However, it is not expected that the same substitution of the PN_OFFSET will work in the case of load information broadcasting, because the PN_0FFSET to Walsh concealment index mapping changes between mobile stations. This sector load information may be included in, for example, other existing CDMA2000 layer 3 (L3) messages, such as, for example, an extended channel assignment message (ECAM) or a universal handover indication message (UHDM). In this construction, the payload information broadcast message may also include a MAC_ID field and a WALSH JVIASK field. The base station usually sets the MAC-ID field (which specifies a MAC identifier) as the MAC identifier assigned to the mobile station, where the mobile station will match this message via F-PDCH The transmission is decoded simultaneously with the F-PDCH sub-packet transmission. If the MAC_ID has a first value, the BS 104 includes a WALSH_MASK field in the load information broadcast message and omits other fields. Other remaining fields may include, for example, an EP-SIZE field, an ACID field, a SPID field, an AI-SN field, an LWCI field, an EXT-MSG-TYPE field, and a RESERVED field . For example, if the MAC_ID is set to * 0000000 (T, the base station includes the WALSH_MASK field and the remaining fields are omitted. 98232.doc -35- 200541355 If the MAC_ID has a second value, the BS 104 The load information broadcast message includes the PN_OFFSET and PN_LOAD bits. For example, if the MAC_ID is set to '0000000Γ', the base station may include the PN_OFFSET and PN_LOAD fields. If the MAC_ID has the first Three values, the BS 104 includes REV_CQICH_COVER (Walsh concealment index corresponding to an AS sector pilot) and PN_LOAD fields in the dedicated load information message transmitted via the F-PDCCH. If the MAC_ID has a fourth value, the BS 104 includes the PN_OFFSET and PNJLOAD blocks in the load information broadcast message transmitted through the F-PDCH. If the MAC_ID has another value, the BS 104 includes other remaining fields in the load information broadcast message and the WALSHJMASK field is omitted. , PN_OFFSET field and PN_LOAD field. For example, the base station can omit the WALSH_MASK field and the PN_OFFSET and PN_LOAD fields and include the remaining fields. Figure 7 is a flowchart showing the details The operation of the remote station according to another aspect of the present invention is described. In this aspect, a BS 104 is provided, which includes a plurality of sectors, a processor, and a transmitter. Each sector may have A plurality of adjacent sectors. At step 710, the processor determines sector load information, and at step 720, the transmitter transmits the sector load information. A current serving sector is transmitted for a fan of all adjacent sectors. Zone load information. For example, F-PDCH or other appropriate FL channels can be used to independently send the sector load information to each user in a dedicated way. Figure 8 is a flow chart. 9832.doc -36- 200541355 operation of a wireless communication device according to yet another aspect of the present invention. In this other aspect, an MS 106 served by a current serving sector is provided. The MS 106 includes a receiver , A channel quality estimator 335, a memory, and a processor. At step 810, the receiver receives sector load information for each sector in the active set (AS) of the MS 106. At step 820, Channel quality estimator 335 measures MS 106 Carrier to interference (C / I) ratio of each sector in the active set (AS). Memory 355 stores the carrier to interference (C / I) ratio measurement of each sector in the active set (AS) of the MS 106 At step 830, the processor determines a new serving sector from the host based on the carrier-to-interference (C / I) ratio measurement and sector load information for each of the AS sectors. In the embodiment of FIG. 6, the sector load information may include a load information broadcast message, which includes a PN_OFFSET block (which contains a PN_OFFSET value) and a PN_LOAD field (which contains corresponding load value information). . If the F-PDCCH message corresponding to the PN_OFFSET field is not received, the default value of PN_LOAD for the pilot can be 0000, 〇 If the last update of PN_LOAD Far before 1 \ time, you can reset PN_LOAD to f0000 ,. The Tx value or the preset PN_LOAD or both can be defined in the standard or signal transmission by L3, or both can be achieved. If the processor determines that the value of PN_OFFSET matches any of the AS sector pilots, the memory 355 stores the value of PN_L0AD. Alternatively, when a received UHDM adds a new sector pilot to the AS, all PN_LOAD values may be stored for future use. When the new serving sector is determined, the processor may modify the measured load 98232.doc -37- 200541355 wave interference (c / i) ratio. In one construction, the processor adds a proportional version of the corresponding value of pN-10ad to the measured carrier-to-interference (c / i) ratio. In a consistent embodiment, when the MS determines the best serving sector, it can modify the addition by adding the PN_LOAD value to the measured c / m (expressed as a crime), where PN_L0AD Interpreted as two supplementary binary numbers in ldB. The range and resolution of the load can be defined in other ways. It should be noted that the MS operation is similar regardless of whether the Bs chooses to use a dedicated program or a broadcast program to deliver the honeycomb load information. It should also be noted that in all the embodiments described above, the method steps can be interchanged without departing from the scope of the invention.
