Description

The following description refers in general to wireless communications and more particularly to schemes for quick access to resources.

DESCRIPTION OF THE PREVIOUS TECHNIQUE

Wireless communication systems are widely developed to provide various types of communication content such as voice, data and so on. These systems can be multiple access systems capable of supporting communication with multiple users by sharing available system resources (for example, bandwidth and transmission power).

Examples of such multiple access systems include code division multiple access systems (CDMA), time division multiple access systems (TDMA), frequency division multiple access systems (FDMA), and multiple access systems by orthogonal frequency division (OFDMA).

Wireless communication systems have become a major mechanism by which most people in the world communicate. Wireless communication devices have become smaller and more powerful in order to meet the needs of consumers, improve portability and convenience. The increase in the processing power of mobile devices such as cell phones has led to an increase in demands on wireless network transmission systems.

A typical wireless communication network (for example, employing frequency division techniques,

2/29 time and code) includes one or more base stations that provide a coverage area and one or more mobile terminals (for example, wireless) that can transmit and receive data within the coverage area. A typical base station can simultaneously transmit multiple data streams for broadcast, multicast and / or single-stream services, where a data stream is a data stream that can be independent of the receiving interest for a mobile terminal. A mobile terminal within the coverage area of that base station may be interested in receiving one, more than one or all of the data streams carried by the composite stream. Likewise, a mobile terminal can transmit data to the base station or another mobile terminal.

In Long Term Evolution (LTE) systems, a random access channel (RACH) can be used when a terminal or user equipment (UE) requires resources to establish a connection with the base station (for example, Node B or access network). The random access channel parameters are periodically diffused by Node B in the common downlink control channel (CCCH). The UE can transmit via RACH only after reaching downlink synchronization and obtaining the most current RACH parameters. RACH is also used for layer 1 synchronization in Uplink and request for uplink air link resource assignment. In the orthogonal nature of the uplink overhead interface (for example, OFDM or OFDMA systems), it may be necessary for RACH resources to be reserved and used only for access. The use of RACH is in bursts and can be much less than the use of the programmed traffic data channel. Therefore, there is a need for minimal data to be transmitted on the RACH while ensuring short access delays.

10/29

As used in this order, the terms component, module, system and the like must refer to a computer-related entity, whether hardware, firmware, a combination of hardware and software, software, or running software. For example, a component can be, but is not limited to, a process running on a processor, a processor, an object, an executable element, a chain of execution, a program and / or a computer. For purposes of illustration, both an application running on a computing device and the computing device itself can be a component. One or more components can reside within a process and / or chain of execution and a component can be located on a computer and / or distributed between two or more computers. In addition, these components can be executed from various computer-readable media having several data structures stored in them. Components can communicate via local and / or remote processes such as according to a signal having one or more data packets (for example, data from a component interacting with another component on a local system, a distributed system, and / or through network such as the Internet with other systems using a signal).

In addition, several modalities are described here with respect to a mobile device. A mobile device can also be called a system, subscriber unit, subscriber station, mobile station, mobile, remote station, remote terminal, access terminal, user terminal, terminal, wireless communication device, user agent, device or user equipment (UE). A mobile device can be a cell phone, a cordless phone, a

11/29

Session Initiation Protocol (SIP), a local wireless access station (WLL), a personal digital assistant (PDA), a portable device with wireless capability, a computing device, or other connected processing device to a wireless modem.

In addition, several modalities are described here with respect to a base station. A base station can be used to communicate with mobile devices and can also be referred to as an access point, Node B, or some other terminology.

In addition, various aspects or features described here can be implemented as a method, device or article of manufacture using standard engineering and / or engineering techniques. The term manufacturing article as used here should encompass a computer program accessible from any computer-readable device, carrier or media. For example, computer-readable media may include, but is not limited to, magnetic storage devices (for example, hard disk, floppy disk, magnetic strips, etc.), optical discs (for example, compact disk (CD), disk digital versatile (DVD), etc.), smart cards, and flash memory devices (eg, EPROM, card, stick, pen drive, etc.).

Referring now to figure 1, a system 100 that performs optimal downlink transmission in a wireless communication environment is illustrated according to several

12/29 modalities. The base station 102 is configured to communicate with one or more mobile devices 104. The base station 102 consists of an optimization component 106 that allows the multiplexing of the localized and distributed transmissions and a receiving component 108 that, for example, receives information regarding the capabilities of the base station. The optimization component 106 allows for downlink transmission so that frequency diversity is achieved and the overhead costs associated with the transmission are mitigated through various schemes, as discussed below. As can be appreciated, the multiplexing of localized and distributed transmissions allows for the accommodation of various traffic services, user capacities and additionally allows a user of one or more mobile devices 104, to take advantage of the channel properties. In addition, for example, one or more mobile devices 104 may provide optimization component 106 at base station 102 with information related to the capabilities of the mobile device, an estimate of downlink channel conditions, and subscriber data. It can also be appreciated that the base station 102 can determine a percentage of high speed versus low speed users, store subscriber data and information related to the capabilities of the mobile device. Such capabilities of the base station 102 may additionally allow the optimization component 106 to choose the ideal multiplexing scheme according to the surrounding conditions.

With reference to figures 2 and 3, the methodologies for a quick access communication system are illustrated. While, for the sake of simplicity of explanation, the methodologies are illustrated and described as a series of acts, one must understand and appreciate that the

13/29 methodologies are not limited by the order of the acts, since some acts may, according to the matter claimed, occur in a different order and / or simultaneously with other acts than was illustrated and described here. For example, those skilled in the art will understand and appreciate that a methodology can alternatively be represented as a series of interrelated states or events, such as in a state diagram. In addition, not all of the illustrated acts may be necessary to implement a methodology in accordance with the claimed matter.

Turning specifically to figure 2, a methodology 200 that facilitates a quick access procedure in a wireless communication system (for example, OFDM or OFDMA systems) is illustrated. The method can be used for initial access, synchronization when the terminal has lost synchronization or is not synchronized with the access network, or handoff. The method starts at 202, an access poll is transmitted to the access network (Node B). In one aspect, the access poll is transmitted on the random access channel (RACH). To minimize the use of uplink resources, only one preamble is transmitted. The preamble can include C / I downlink information (allows power control of an access grant message sent in downlink in response to the access probe, discussed below), return of channel quality indicator, information related to QoS ( allows the programmer to select and / or prioritize the initial resource assignment), Random ID (reduces the likelihood of identical access probes from different UEs reaching Node B at the same time) and cell ID (used to scramble the access probe so that the poll is successfully decoded on only target Node B). a

14/29 access probe preamble comprises an access sequence. The access sequence is derived from the UE downlink C / I, QoS information and / or a random number used to avoid possible collisions. In one aspect, all 5 access sequences are orthogonal. The access sequence is scrambled before transmission by the cell-specific scramble sequence. In another aspect, the scrambling sequence is not only a function of the cell ID but also in addition to the cell ID a function 10 of the MAC ID (any type of UE ID is sufficient).

In one aspect, after the transmission of the access poll the method moves to 204, a determination is made as to whether an access grant is received in response to the access poll. If the access concession is received, the method goes to 206 after decoding the access concession using the information from the access probe. In 206, a connection opening request message (for example, ConnectionOpenRequest) is transmitted and the method waits for a response. In 208, a connection open response message (ConnectionOpenResponse) is received in response to the connection open request message. In another aspect, if the terminal has already received a MAC ID (for example, when the terminal is in the active state), the method described in 206 and 208 can be eliminated and the terminal can start exchanging data with the access network. .

With reference again to 204, if the grant of access is not received after a predetermined time, the method moves to 208. In 210, a determination is made 30 as to whether a predetermined maximum number of retransmissions has been achieved. If the maximum number of retransmissions for the access probe is being reached, then the method goes to 212. In 212, the

15/29 transmission power is reset to the original level and the access probe is retransmitted. The method goes to 204 to verify that the access grant has been received. If the maximum number of retransmissions from poll 5 has not been reached, the method goes to 214. In 214, the poll is retransmitted with greater power. The method goes to 204 to verify that the access grant has been received.

Referring now to Figure 3, an illustrative methodology 10 that facilitates receiving an access probe in a wireless communications system is illustrated. The method starts at 302, an access poll comprising an access sequence being received. If the access probe is detected successfully, then the method moves to 304. In 304, the access network generates an access grant. The access grant is associated with the access probe and uses information from the received access probe. The access network determines the parameters to provide the terminal associated with the access probe 20 so that the terminal exchanges data with the access network. Granting access, among other things, comprises a terminal MAC ID, uplink resource assignment and uplink settings. The granting of access can be shuffled and protected using error correction schemes. If the access concession is transmitted on a broadcast channel to several terminals, then it can be scrambled using information from the access probe, so that only the requester is able to decode the access concession. For example, Node B shuffles the access concession with the sequence of the preamble of access it received. Only the UE that has selected the corresponding access preamble sequence can decode the access grant. After granting access is

16/29 generated, in 306, the method transmits the grant of access and waits for the request for an open connection. At 308, the open connection request message is received. After authentication of the terminal, in 310, the open connection reply message is transmitted.

In another aspect, the methodologies illustrated in figures 2 and 3 can be applied to the handoff scheme. The EU negotiates the handoff with the source Node B. In parallel, the source Node B negotiates the handoff with the target Node B. Before the UE can start exchanging data on the target Node B, the UE transmits the synchronization message in the direction of the target Node B. The synchronization message consists of the access preamble and is transmitted on the RACH. The scramble sequence is a function of the target cell ID as its MAC ID. When uplink synchronization is achieved, the target Node B sends the access grant to the UE.

In another aspect, the methodologies illustrated in figures 4 and 5 can be applied to synchronization. Turning specifically to figure 4, a methodology 400 that facilitates a quick access procedure in a wireless communication system (for example, OFDM or OFDMA systems) is illustrated. The method can be used for synchronization when the terminal has lost synchronization or is not synchronized with the access or handoff network. method 400 is executed at the terminal determining that it is not in sync with the access network. The terminal may lose synchronization with the access network if the terminal transitions to standby from active mode, deep fading, or during a handoff procedure. In one aspect, the method starts at 404, the access terminal transmits an access signature (may be referred to as an access probe) to the access network (Node B). In one aspect, access polling

17/29 is transmitted on RACH. The access poll can include C / I downlink information, channel quality indicator return, QoS related information, Random ID, cell ID, or MAC ID flag. Since this method is for new synchronization, the terminal may already have a MAC ID and not need a new MAC ID for the access network. In one aspect, the access poll MAC ID flag can be configured to indicate that a new MAC ID is not desired or that the MAC ID flag is not used.

After the transmission of the access probe, the method proceeds to 406, the terminal receives an UL access grant from the access network (Node B) in response to the access probe. In one aspect, the first UL grant message received in response to the access probe may contain information about UL resources, timing parameters to adjust the timing and a part of MAC ID. In one aspect, the MAC ID part can be set to NULL (for example, a series of zeros or any pattern used to indicate unusable data) for the first UL grant message received in response to the access probe. The terminal can ignore the processing of the MAC ID part of the grant message. Where the MAC ID part is not NULL (the access network has assigned a new MAC ID), the terminal can continue to ignore the new MAC ID and use any previously assigned MAC ID stored in memory. If a terminal does not have a MAC ID assigned, then the terminal can use the MAC ID of the access grant message. In another aspect, the access network can provide the MAC ID extracted from the memory based on the information from the access probe. In this respect, the UL grant message can comprise different sets of parameters and the terminal

18/29 can process the MAC ID part other than the UL grant message.

With reference to 408, using the parameters received from the access grant, communication is established with the access network in which the terminal begins to communicate user data. In one aspect, the terminal provides its MAC ID when transmitting on the uplink shared channel. The access network can store this MAC ID in memory. At 410, the terminal receives a second or subsequent UL access grant message from the access network. The terminal processes the MAC ID portion of all UL grant messages received after receiving the first UL grant grant message (discussed in 406). After that, in 412, the terminal transmits user data on the uplink shared channel, but does not provide the MAC ID as part of subsequent user data transmissions.

Referring now to figure 5, an illustrative methodology 500 that facilitates receiving an access probe in a wireless communications system. The method starts at 502, an access poll is being received. If the access probe is detected successfully, then the method goes to 504. In 504, the access network generates an access concession. The access grant is associated with the access poll and user information from the received access poll. The access network determines the parameters to provide the terminal associated with the access probe so that the terminal exchanges data with the access network. The granting of access, among other things, comprises the allocation of uplink resources and uplink adjustments. In one aspect, the access poll can include a MAC ID flag. If the MAC ID flag is part of the access poll and is configured (in this way, the

19/29 terminal is requesting the access network to assign a MAC ID), so a MAC ID can be included as part of the access grant message. In another aspect, the access poll does not include any indication that a MAC ID was requested. In that regard, the MAC ID portion of the UL access grant message, transmitted in response to the access poll indicating that the MAC ID is not requested, provides the MAC ID as NULL. In another aspect, the access survey comprises a first indicator. If the first indicator is configured, then the access network determines the access probe as a zero rate request and the access network can only provide timing adjustment or power adjustment. In 506, the access network receives a first message after granting access. The first message can contain MAC ID or user data. In 508, the access network updates the memory to indicate that all future messages, for example, a second UL access grant message, will use the received MAC ID.

Referring now to Figure 6, a wireless communication system 600 is illustrated according to the various modalities presented here. System 600 may comprise one or more base stations 602 (e.g., access points) in one or more sectors that receive, transmit, repeat, etc., wireless communication signals to each other and / or to one or more mobile devices 604. Each base station 602 can comprise a transmitting chain and a receiving chain, each of which can, in turn, comprise a plurality of components associated with signal transmission and reception (e.g., processors, modulators, multiplexers , demodulators, demultiplexers, antennas, ...) as will be appreciated by those skilled in the art.

20/29

604 mobile devices can be, for example, cell phones, smart phones, laptops, portable communication devices, portable computing devices, satellite radios, global positioning systems, PDAs, and / or any other device suitable for communication via the 600 wireless communication system.

Base stations 602 can broadcast content to mobile devices 604 by employing OFDM or OFDMA techniques. Frequency division-based techniques such as OFDM typically separate the frequency spectrum into separate channels, for example, the frequency spectrum can be divided into uniform parts of bandwidth (frequency range). OFDM effectively divides the total system bandwidth into multiple orthogonal frequency channels. Frequency channels can use either HARQ Sync or Async assignments, depending on system requirements. In addition, an OFDM system can use time and / or frequency division multiplexing to achieve orthogonality between multiple data transmissions to multiple base stations 602.

Referring now to Figure 7A, a system 700 that facilitates quick access in wireless communication is illustrated. System 700 can include a module 702 for generating an access probe, a module 704 for receiving a first access grant, and module 706 for transmitting user data. The modules 702, 704 and 706 can be a processor or any electronic device and can be coupled to the memory module 708.

Referring now to Figure 7B, a system 750 that facilitates quick access in wireless communication is illustrated. The system 750 can include a module 752 for receiving an access probe, a module 754 for

21/29 generate an access grant in response to the received access probe and a 756 module for receiving user data. Modules 752 to 756 can be a processor or any electronic device and can be attached to the memory module 760.

Figure 8 is an illustration of a terminal or user device 800 that provides other sector communication in a wireless communication environment according to one or more aspects presented here. Terminal 800 comprises an 802 receiver that receives a signal, for example, one or more receiving antennas, and performs typical actions (for example, filters, amplifies, converts downward, etc.) the received signal and digitizes the conditioned signal to obtain of samples. A demodulator 804 can demodulate the samples and provide the received pilot symbols for an 806 processor.

Processor 806 can be a dedicated processor for analyzing information received by the receiving component 802 and / or for generating information for transmission by a transmitter 814. Processor 806 can be a processor that controls one or more components of terminal 800, and / or a processor that analyzes the information received by the receiver 802, generates information for transmission by a transmitter 814, and controls one or more components of terminal 800. Processor 806 can use any of the methodologies described here, including those described in relation to the figures 2 and 3.

In addition, terminal 800 may include a transmission control component 808 that analyzes the incoming input, including confirmations of successful transmissions. Acknowledgments (ACK) can be received from the server sector and / or from a neighboring sector. Confirmations may indicate that a previous transmission was received with

22/29 successfully and decoded by one of the access points. If no acknowledgment is received, or if a negative acknowledgment (NAK) is received, the transmission can be resent. The transmission control component 808 can be incorporated into the processor 806. It should be appreciated that the transmission control component 808 can include the transmission control code that performs the analysis with respect to determining the receipt of confirmation.

Terminal 800 can additionally comprise memory 810 which is operationally coupled to processor 806 and which can store information related to transmissions, an active set of sectors, methods for controlling transmissions, look-up tables comprising information related to them, and any other appropriate information related to the transmissions and active cluster sectors as described here. It will be appreciated that the data storage components (e.g., memories) described herein can be volatile memory or non-volatile memory, or can include both volatile and non-volatile memory. For purposes of illustration, not limitation, non-volatile memory may include read-only memory (ROM), programmable ROM (PROM), electrically programmable ROM (EPROM), electrically erasable ROM (EEPROM), or flash memory. Volatile memory can include random access memory (RAM), which acts as an external cache memory. For purposes of illustration and not limitation, RAM is available in many forms such as synchronized RAM (SRAM), dynamic RAM (DRAM), synchronous DRAM (SDRAM), dual data rate SDRAM (DDR SDRAM), enhanced SDRAM ( ESDRAM), DRAM Synchlink (SLDRAM), and RAM Direct Rambus (DRRAM). The memory 810 of the present systems and methods must comprise, but are not limited to, these and any other suitable types of

23/29 memory. Processor 806 is connected to a symbol modulator 812 and transmitter 814 that transmits the modulated signal.

Figure 9 is an illustration of a 900 system that facilitates other sector communication in a communication environment according to several aspects. The system 900 comprises an access point 902 with a receiver 910 that receives signals from one or more terminals 904 through one or more receiving antennas 906, and transmits to one or more terminals 904 through a plurality of transmitting antennas 908. The terminals 904 may include terminals supported by access point 902, in addition to terminals 904 supported by neighboring sectors. In one or more aspects, receiving antennas 906 and transmitting antennas 908 can be implemented using a single set of antennas. The receiver 910 can receive information from the receiving antennas 906 and is operationally associated with demodulator 912 which demodulates the received information. The 910 receiver can be, for example, a Rake receiver (for example, a technique that individually processes multipath signal components using a plurality of baseband correlators, ...), a MMSE-based receiver, or some another suitable receiver for separating the terminals assigned to it, as will be appreciated by those skilled in the art. According to several aspects, multiple receivers can be employed (for example, one per receiving antenna) and such receivers can communicate with each other to provide improved estimates of user data. The demodulated symbols are analyzed by a 914 processor that is similar to the processor described above with respect to figure 10, and is coupled to a 916 memory that stores information related to the terminals, resources

Assigned 24/29 associated with terminals and the like. The receiver output for each antenna can be processed together by the receiver 910 and / or processor 914. A modulator 918 can multiplex the signal for transmission by a transmitter 920 through transmitting antennas 908 to terminals 904.

Access point 902 further comprises a terminal communication component 922, which may be a separate processor from, or integral with, processor 914. Terminal communication component 922 may obtain resource assignment information for terminals supported by neighboring sectors . In addition, the terminal communication component 922 can provide assignment information for neighboring sectors to the terminals supported by access point 902. The assignment information can be provided via signaling on the return transport channel.

Based on the information related to the allocated resources, the terminal communication component 922 can direct the detection of transmissions from the terminals supported by neighboring sectors, in addition to the decoding of received transmissions. The memory 916 can hold the packets received from the terminals before receiving the allocation information required for decoding the packets. The terminal communication component 922 can also control the transmission and receipt of acknowledgments indicating the successful reception and decoding of transmissions. It will also be appreciated that the terminal communication component 922 may include transmission analysis code that performs control based on utility with respect to the allocation resources, identification of terminals for soft-handoff, decoding of transmissions and the like. The code

25/29 terminal analysis can use methods based on artificial intelligence in relation to the realization of inference and / or probabilistic determinations and / or determinations based on statistics in relation to the optimization of the performance of the terminal.

Figure 10 illustrates an exemplary wireless communication system 1000. The wireless communication system 600 features a terminal and two access points for the sake of brevity. However, it should be appreciated that the system may include one or more access points and / or more than one terminal, where the access points and / or additional terminals may be substantially similar or different from the exemplary access points and terminals described below. Additionally, it must be appreciated that the access points and / or terminals can employ the systems (figures 1 and 4 to 9) and / or methods (figures 2 and 3) described here.

Figure 10 illustrates a block diagram of a terminal 1004, a server access point 1002x that supports terminal 1024 and a neighboring access point 1002Y in the multi-port multi-access communication system 1000. At access point 1002X, a data processor transmission data (TX) 1014 receives traffic data (i.e. information bits) from a data source 1012 and signaling and other information from a controller 1020 and a programmer 1030. For example, programmer 1030 can provide assignments of carriers to the terminals. In addition, a 1022 memory can hold information regarding current or previous assignments. The TX 1014 data processor encodes and modulates the received data using multi-port modulation (eg OFDM) to provide modulated data (eg OFDM symbols). A 1016 transmitting unit (TMTR) then

26/29 processes the modulated data to generate a downlink modulated signal which is then transmitted from a 1018 antenna.

Before transmitting the assignment information to terminal 1004, the programmer can provide assignment information for access point 1002Y. The assignment information can be provided via signaling on the return transport channel (e.g., a T1 line) 1010. Alternatively, the assignment information can be provided to an access point 1002Y after transmission to terminal 1004.

At terminal 1004, the transmitted and modulated signal is received by an antenna 1052 and provided to a receiver unit (RCVR) 1054. Receiver unit 1054 processes and digitizes the received signal to provide samples. A 1056 received data processor (RX) then demodulates and decodes the samples to provide decoded data, which can include retrieved traffic data, messages, signaling and so on. Traffic data can be provided for a data store 1058, and the carrier assignment information for terminal 1004 is provided for a controller 1060.

Controller 1060 directs the data transmission in uplink using the specific carriers that have been assigned to terminal 1004 and indicated in the received carrier assignment. A 1062 memory can hold information regarding the allocated resources (for example, frequency, time and / or code) and other related information.

For terminal 1004, a TX data processor 1074 receives traffic data from a data source 1072 and signalization and other information from the controller 1060. The various types of data are encoded and modulated by the

27/29 TX 1074 data processor using the carriers assigned and further processed by a transmitting unit 1076 to generate an uplink modulated signal which is then transmitted from antenna 1052.

At access points 1002X and 1002Y, signals transmitted and modulated from terminal 1004 are received by antenna 1018, processed by a receiver unit 1032, and demodulated and decoded by an RX 1034 data processor. Signals transmitted can be decoded based on in the assignment information generated by the server access point 1002X and provided to neighboring access point 1002Y. In addition, access points 1002X and 1002Y can generate an acknowledgment (ACK) that can be provided to the other access point (1002X or 1002Y) and / or to terminal 1004. Decoded signals can be provided for a 1036 data store The receiving unit 1032 can estimate the quality of the received signal (for example, the signal-to-noise ratio (SNR) received) for each terminal and provides that information to the 1020 controller. The RX 1034 data processor provides the retrieved feedback information for each terminal for controller 1020 and programmer 1030.

Programmer 1030 uses the feedback information to perform various functions such as (1) selecting a set of terminals for data transmission on the reverse link and (2) assigning the carriers to the selected terminals. Carrier assignments for the programmed terminals are then transmitted on the direct link to those terminals.
