Description

TECHNICAL FIELD

The technology discussed in this patent application relates generally to wireless communication, and more particularly, to devices, methods, and systems for establishing communication network connections for calls. Embodiments of the present invention improve conventional procedures in a manner that conserves power and enabling positive user experience.

BACKGROUND

Wireless communication systems are widely deployed to provide various types of communication content such as voice, data, and so on. These systems may be multiple-access systems capable of supporting communication with multiple users by sharing the available system resources (e.g., bandwidth and transmit power). Examples of such multiple-access systems include code division multiple access (CDMA) systems (e.g., cdma2000 1× (IS-2000)), time division multiple access (TDMA) systems, frequency division multiple access (FDMA) systems, 3GPP Long Term Evolution (LTE) systems, and orthogonal frequency division multiple access (OFDMA) systems.

Generally, a wireless multiple-access communication system can simultaneously support communication for multiple mobile stations (MS). Each MS communicates with one or more base stations (BS), such as a Node B or other access point, via transmissions on the forward and reverse links. The forward link (or downlink) refers to the communication link from the BSs to the MSs, and the reverse link (or uplink) refers to the communication link from the MSs to the BSs.

In a network operating according to a Code Division Multiple Access 2000 1× Radio Transmission Technology (CDMA2000 1×RTT) standard (also referred to herein as “1× network”), mobile stations and base stations desiring to establish a traffic channel require an exchange of multiple messages for channel setup. The requirement of these multiple messages leads to large call setup times, thereby degrading the user experience.

DETAILED DESCRIPTION

Various aspects are now described with reference to the drawings. In the following description, for purposes of explanation, numerous specific details are set forth in order to provide a thorough understanding of one or more aspects. It may be evident, however, that such aspect(s) may be practiced without these specific details.

Described herein are various aspects related to improving channel setup in a wireless network, such as a network operating according to a Code Division Multiple Access 2000 1× Radio Transmission Technology (CDMA2000 1×RTT) standard (also referred to herein as “1× network”). Rather than requiring multiple messages for channel setup, the described apparatus and methods include sending a single message from the base station to the mobile station in order to initiate channel setup. A used herein, the single message may be referred to as a universal channel assignment message. For example, the single message may include both channel assignment parameters and service option configuration parameters to enable channel setup. In an optional aspect, the mobile station may send the base station a capability indicator to identify that the mobile station supports traffic channel initialization using the single message. Further, in an aspect, the base station may condition the sending of the single message on receiving the capability indicator from the mobile station. Moreover, in another optional aspect, the describe apparatus and methods may include configuring the mobile station to recognize that the base station has acquired a reverse link of the traffic channel based on the mobile station receiving a signaling message from the base station or a frame with a data rate equal to or greater than a ¼ rate from the base station. Thus, the described aspects may reduce channel setup time, and thereby avoiding degradations in an experience of a user of the mobile device when setting up a call.

Referring to FIG. 1, a wireless communication system 10 is illustrated that enables improved channel setup between a mobile station 12 and a base station 14. Mobile station 12 can be substantially any type of mobile access terminal, modem (or other tethered device), machine-to-machine (M2M) device, a portion of a relay or other network component, and/or the like, that can register with a base station or wireless network, generate an origination message, or receive and respond to paging signals in a wireless network. Base station 14 can be substantially any type of network access point, such as a macrocell, femtocell, picocell, or similar base station, a mobile base station, a relay, a mobile station communicating in peer-to-peer or ad-hoc mode with mobile station 12, and/or the like, that can communicate channel establishment messages to mobile stations in a wireless network. For example, wireless communication system 10, and/or mobile station 12 and base station 14, may operate according to a Code Division Multiple Access 2000 1× Radio Transmission Technology (CDMA2000 1×RTT) standard.

Mobile station 12 can include a communication channel establishment component 16 that enables mobile device 12 to establish a traffic channel with base station 14 based on a single message 18 received from base station 14. For example, single message 18 includes channel assignment parameters 20 and service option configuration parameters 22. In an aspect, for example, channel assignment parameters 20 may include some or all of the parameters of an Enhanced Channel Assignment Message (ECAM). Also, in an aspect, for example, service option configuration parameters 22 may include some or all of the parameters of Service Connect Message (SCM).

In an aspect, communication channel establishment component 16 may include an initiator component 24 for generating and sending a first message 26 to initiate setup of a traffic channel with base station 14. For example, first message 22 may include, but is not limited to, one of a registration message (RGM), an origination message (ORM), a page response message (PRM), or a general extension message (GEM) message.

In an optional aspect, initiator component 20 may be further configured to generate and send a capability indicator 28 to base station 14. In an aspect, for example, capability indicator 28 identifies that mobile station 12 supports traffic channel initialization using single message 18. Further, in an aspect, capability indicator 28 may be included in first message 26.

Further, in an aspect, communication channel establishment component 16 also may include an establisher component 30 for receiving single message 18 including channel assignment parameters 20 and service option configuration parameters 22 from base station 14 in response to first message 22. Moreover, establisher component 30 is further configured to establish the traffic channel using channel assignment parameters 26 and service option configuration parameters 28. In an aspect, for example, establisher component 30 may perform a traffic channel initialization procedure, which may include acquiring a forward link of the traffic channel and transmitting a preamble to base station 14, and receiving an acknowledgement from base station 14 after acquisition of a reverse link of the traffic channel by base station 14.

Further, mobile station 12 may receive data from base station 14 and/or transmit data to base station 14 upon establishment of the traffic channel.

Base station 14 can include a communication channel establishment component 32 that enables base station 14 to send single message 18 to mobile device 12 to establish a traffic channel.

In an aspect, communication channel establishment component 32 may include an initiator component 34 configured to receive first message 26 from mobile station 12 to initiate setup of a traffic channel. Optionally, initiator component 34 may be further configured to generate and send a page to mobile station 12 to trigger first message 26 to be sent from mobile station 12.

Moreover, in an aspect, communication channel establishment component 32 may include a channel assignment component 36 configured to send single message 18 including channel assignment parameters 20 and service option configuration parameters 22 to mobile station 12 in response to first message 26. In an aspect, channel assignment component 36 may only send single message 18 upon receipt of capability indicator 28 from mobile station 12. For example, capability indicator 28 may be received separate from or included in first message 26.

Further, communication channel establishment component 32 may include a establisher component 38 configured to establish the traffic channel according to channel assignment parameters 20 and the service option configuration parameters 22 defined by single message 18. In an aspect, establisher component 38 may perform a traffic channel initialization procedure, which may include sending data frames over a forward link of the traffic channel to enable mobile station 12 to acquire the forward link, and receiving in response a preamble from mobile station 12. Additionally, the traffic channel initialization procedure may subsequently include acquiring a reverse link of the traffic channel, and sending an acknowledgement to mobile station 12.

Accordingly, upon establishment of the traffic channel, base station 14 may send data to or receive data from mobile station 12.

It will be appreciated that, in accordance with one or more aspects described herein, inferences can be made regarding channel setup, and/or the like, as described. As used herein, the term to “infer” or “inference” refers generally to the process of reasoning about or inferring states of the system, environment, and/or user from a set of observations as captured via events and/or data. Inference can be employed to identify a specific context or action, or can generate a probability distribution over states, for example. The inference can be probabilistic—that is, the computation of a probability distribution over states of interest based on a consideration of data and events. Inference can also refer to techniques employed for composing higher-level events from a set of events and/or data. Such inference results in the construction of new events or actions from a set of observed events and/or stored event data, whether or not the events are correlated in close temporal proximity, and whether the events and data come from one or several event and data sources.

Referring to FIG. 5, an example system 80 for channel setup in a wireless communication system is illustrated. For example, system 80 can reside at least partially within a mobile station, such as mobile station 12 (FIG. 1).

In one example, electrical components 84, 86, and 88 can comprise at least one processor, or each electrical component 84, 86, and 88 can be a corresponding module of at least one processor. Moreover, in an additional or alternative example, electrical components 84, 86, and 88 can be a computer program product including a computer readable medium, where each electrical component 84, 86, and 88 can be corresponding code.

Referring to FIG. 6, an example system 100 for channel setup in a wireless communication system is illustrated. For example, system 100 can reside at least partially within a mobile station, such as mobile station 12 (FIG. 1). It is to be appreciated that system 100 is represented as including functional blocks, which can be functional blocks that represent functions implemented by a processor, software, or combination thereof (e.g., firmware). System 100 includes a logical grouping 102 of electrical components that can act in conjunction.

Referring to FIG. 7, a multiple access wireless communication system according to one embodiment is illustrated. An access point 700 (AP) includes multiple antenna groups, one including 704 and 706, another including 708 and 77, and an additional including 712 and 714. In FIG. 7, only two antennas are shown for each antenna group, however, more or fewer antennas can be utilized for each antenna group. Access terminal 716 (AT) is in communication with antennas 712 and 714, where antennas 712 and 714 transmit information to access terminal 716 over forward link 720 and receive information from access terminal 716 over reverse link 718. Access terminal 722 is in communication with antennas 704 and 706, where antennas 704 and 706 transmit information to access terminal 722 over forward link 726 and receive information from access terminal 722 over reverse link 724. In a FDD system, communication links 718, 720, 724 and 726 can use different frequency for communication. For example, forward link 720 can use a different frequency then that used by reverse link 718.

Each group of antennas and/or the area in which they are designed to communicate is often referred to as a sector of the access point. In the embodiment, antenna groups each are designed to communicate to access terminals in a sector of the areas covered by access point 700.

In communication over forward links 720 and 726, the transmitting antennas of access point 700 utilize beamforming in order to improve the signal-to-noise ratio of forward links for the different access terminals 716 and 722. Also, an access point using beamforming to transmit to access terminals scattered randomly through its coverage causes less interference to access terminals in neighboring cells than an access point transmitting through a single antenna to all its access terminals.

Moreover, access terminals 716 and 722 and access point 700 can provide functionality to perform channel setup utilizing single message 18 (FIG. 1), as described above.

FIG. 8 is a block diagram of an embodiment of a transmitter system 810 (also known as the access point) and a receiver system 850 (also known as access terminal) in a MIMO system 800. At the transmitter system 810, traffic data for a number of data streams is provided from a data source 812 to a transmit (TX) data processor 814. In addition, it is to be appreciated that transmitter system 810 and/or receiver system 850 can employ the systems (FIGS. 1, 2, and 5-7) and/or methods (FIGS. 3 and 4) described herein to facilitate wireless communication there between. For example, components or functions of the systems and/or methods described herein can be part of a memory 832 and/or 872 or processors 830 and/or 870 described below, and/or can be executed by processors 830 and/or 870 to perform the disclosed functions.

In an embodiment, each data stream is transmitted over a respective transmit antenna. TX data processor 814 formats, codes, and interleaves the traffic data for each data stream based on a particular coding scheme selected for that data stream to provide coded data.

The coded data for each data stream can be multiplexed with pilot data using OFDM techniques. The pilot data is typically a known data pattern that is processed in a known manner and can be used at the receiver system to estimate the channel response. The multiplexed pilot and coded data for each data stream is then modulated (e.g., symbol mapped) based on a particular modulation scheme (e.g., BPS K, QSPK, M-PSK, or M-QAM) selected for that data stream to provide modulation symbols. The data rate, coding, and modulation for each data stream can be determined by instructions performed by processor 830.

The modulation symbols for all data streams are then provided to a TX MIMO processor 820, which can further process the modulation symbols (e.g., for OFDM). TX MIMO processor 820 then provides N_T modulation symbol streams to N_T transmitters (TMTR) 822a through 822t. In certain embodiments, TX MIMO processor 820 applies beamforming weights to the symbols of the data streams and to the antenna from which the symbol is being transmitted.

Each transmitter 822 receives and processes a respective symbol stream to provide one or more analog signals, and further conditions (e.g., amplifies, filters, and upconverts) the analog signals to provide a modulated signal suitable for transmission over the MIMO channel. N_T modulated signals from transmitters 822a through 822t are then transmitted from N_T antennas 824a through 824t, respectively.

At receiver system 850, the transmitted modulated signals are received by N_R antennas 852a through 852r and the received signal from each antenna 852 is provided to a respective receiver (RCVR) 854a through 854r. Each receiver 854 conditions (e.g., filters, amplifies, and downconverts) a respective received signal, digitizes the conditioned signal to provide samples, and further processes the samples to provide a corresponding “received” symbol stream.

An RX data processor 860 then receives and processes the N_R received symbol streams from N_R receivers 854 based on a particular receiver processing technique to provide N_T “detected” symbol streams. The RX data processor 860 then demodulates, deinterleaves, and decodes each detected symbol stream to recover the traffic data for the data stream. The processing by RX data processor 860 is complementary to that performed by TX MIMO processor 820 and TX data processor 814 at transmitter system 810.

A processor 870 periodically determines which pre-coding matrix to use. Processor 870 formulates a reverse link message comprising a matrix index portion and a rank value portion.

The reverse link message can comprise various types of information regarding the communication link and/or the received data stream. The reverse link message is then processed by a TX data processor 838, which also receives traffic data for a number of data streams from a data source 836, modulated by a modulator 880, conditioned by transmitters 854a through 854r, and transmitted back to transmitter system 810.

At transmitter system 810, the modulated signals from receiver system 850 are received by antennas 824, conditioned by receivers 822, demodulated by a demodulator 840, and processed by a RX data processor 842 to extract the reserve link message transmitted by the receiver system 850. Processor 830 then determines which pre-coding matrix to use for determining the beamforming weights then processes the extracted message.

Processors 830 and 870 can direct (e.g., control, coordinate, manage, etc.) operation at transmitter system 810 and receiver system 850, respectively. Respective processors 830 and 870 can be associated with memory 832 and 872 that store program codes and data. For example, processors 830 and 870 can perform functions described herein with respect to channel setup using single message 18 (FIG. 1). Similarly, memory 832 and 872 can store instructions for executing the functionality or components, and/or related data.

As used in this application, the terms “component,” “module,” “system” and the like are intended to include a computer-related entity, such as but not limited to hardware, firmware, a combination of hardware and software, software, or software in execution. For example, a component may be, but is not limited to being, a process running on a processor, a processor, an object, an executable, a thread of execution, a program, and/or a computer. By way of illustration, both an application running on a computing device and the computing device can be a component. One or more components can reside within a process and/or thread of execution and a component can be localized on one computer and/or distributed between two or more computers. In addition, these components can execute from various computer readable media having various data structures stored thereon. The components can communicate by way of local and/or remote processes such as in accordance with a signal having one or more data packets, such as data from one component interacting with another component in a local system, distributed system, and/or across a network such as the Internet with other systems by way of the signal.

Furthermore, various aspects may have been described herein in connection with a terminal, which can be a wired terminal or a wireless terminal. A terminal can also be called a system, device, subscriber unit, subscriber station, mobile station, mobile, mobile device, remote station, remote terminal, access terminal, user terminal, terminal, communication device, user agent, user device, user equipment, or user equipment device. A wireless terminal can be a cellular telephone, a satellite phone, a cordless telephone, a Session Initiation Protocol (SIP) phone, a wireless local loop (WLL) station, a personal digital assistant (PDA), a handheld device having wireless connection capability, a computing device, or other processing devices connected to a wireless modem. Moreover, various aspects are described herein in connection with a base station. A base station can be utilized for communicating with wireless terminal(s) and can also be referred to as an access point, access node, a Node B, evolved Node B (eNB), or some other terminology.

Moreover, the term “or” is intended to mean an inclusive “or” rather than an exclusive “or.” That is, unless specified otherwise, or clear from the context, the phrase “X employs A or B” is intended to mean any of the natural inclusive permutations. That is, the phrase “X employs A or B” is satisfied by any of the following instances: X employs A; X employs B; or X employs both A and B. In addition, the articles “a” and “an” as used in this application and the appended claims should generally be construed to mean “one or more” unless specified otherwise or clear from the context to be directed to a singular form.

The techniques described herein may be used for various wireless communication systems such as CDMA, TDMA, FDMA, OFDMA, SC-FDMA and other systems. The terms “system” and “network” are often used interchangeably. A CDMA system may implement a radio technology such as Universal Terrestrial Radio Access (UTRA), cdma2000, etc. UTRA includes Wideband-CDMA (W-CDMA) and other variants of CDMA. Further, cdma2000 covers IS-2000, IS-95 and IS-856 standards. A TDMA system may implement a radio technology such as Global System for Mobile Communications (GSM). An OFDMA system may implement a radio technology such as Evolved UTRA (E-UTRA), Ultra Mobile Broadband (UMB), IEEE 802.11 (Wi-Fi), IEEE 802.16 (WiMAX), IEEE 802.20, Flash-OFDM®, etc. UTRA and E-UTRA are part of Universal Mobile Telecommunication System (UMTS). 3GPP Long Term Evolution (LTE) is a release of UMTS that uses E-UTRA, which employs OFDMA on the downlink and SC-FDMA on the uplink.
