## Background
PRIORITY CLAIM
This application claims priority from, and is a continuation application of, U.S. patent application Ser. No. 12/535,557, filed on Aug. 4, 2009, and claims priority to U.S. Provisional Patent Application No. 61/168,324, filed on Apr. 10, 2009, the contents of which are expressly incorporated herein by reference in their entireties.


BACKGROUND
Field
The disclosed aspects relate to context sensitive interactions between a content distributor and a wireless communications device over one or more networks.
Background
Broadcast radio stations, such as FM radio stations, may use a system known as a Radio Data System (RDS) or Radio Broadcast Data System (RBDS), both referred to herein as “RDS,” to transmit supplemental information corresponding to their normal radio programming, e.g. music, talk, news, etc. RDS provides a standard protocol for several types of supplemental information transmitted by the broadcast radio stations, such as the identity of the particular radio station, the type of programming, and text information such as the name of an artist and/or song.
For example, broadcast radio stations transmit their programming and the supplemental information in the RDS format as distinct signals multiplexed onto a single carrier. Radio receivers having RDS decoders, such as those included with some wireless communications devices or those in a vehicle, permit a user to listen to the transmitted programming and view the corresponding supplemental information on a display.
Currently, some mobile operators may not include proper resources for supporting interactive FM RDS service. Additionally, mobile operators may not include proper resources for supporting back-end database integration that would allow mobile users to interact with information available to FM RMS enabled devices. Thus, improved apparatus and methods for providing interactivity between non-FM RDS enabled mobile devices and mobile operators to allow access to RDS related content are desired.

It may be evident, however, that such aspect(s) may be practiced without these specific details.
The ability to access secondary and/or context related content associated with primary content distributed by a first service provider to a device that may be unable to directly access the secondary and/or content related content may be accomplished through using interactivity between the device and a second service provider, wherein the second service provider is capable of processing the secondary and/or context content. In particular, the present aspects enable a wireless device to receive a radio signal, such as an FM signal, and access secondary content associated with the radio signal, such as FM RDS data, through a second service provider, such as a cellular network service provider, internet service provider, etc., without requiring the device to be able to directly access the secondary content.
With reference to FIG. 1, a block diagram of a communication network 100 according to an aspect is illustrated. Communication network 100 may include one or more of wireless communications devices 110 (FIG. 1 depicts an ellipsis next to communications device 110 as a representation of a possible plurality of devices not shown) connected to a communication network 120, e.g., a CDMA network, a GPRS network, a UMTS network, IP network, FM based network, AM based network, satellite radio network, and other types or combinations of types of communication networks. Communication network 100 may further include a plurality of servers 130, 140 connected to one or more communication networks 120. In one aspect, the plurality of servers includes first service provider server 130 and second service provider server 140. In one exemplary aspect, server 130 may communicate content item 132 to wireless communications device 110 via a FM based network, while server 140 may communicate with wireless communications device 110 via a CDMA network, IP network, etc. In another aspect, additionally or in the alternative, content item 132 may be communicated (e.g. streamed) to wireless communications device 110 via a CDMA network, IP network, etc. In one aspect, wireless communications device 110 may further include a content module 112. Further, content module 110 may include bookmark module 116 and device operation identifying module 118.
In one aspect, communication network 100 may further include second computing device 150. In such an aspect, second computing device 150 may be communicatively coupled to wireless communications device 110 and further may be able to receive content item identifying data 152. For example, second computing device 150 may include a personal navigation device (PND) capable of receiving FM RDS data which may accompany distribution of content item 132 by first service provider server 130. In such an exemplary aspect, second computing device 150 may further assist wireless communications device in identifying a distributed content item 132 through content item identifying data 152 to generate a content item request 114. In another exemplary aspect, second computing device 150 may include computer with network access, such as internet access, to allow second computing device 150 to retrieve content item identifying data 152 from a website, or the like, associated with first service provider server 130. In such an exemplary aspect, second computing device 150 may further assist wireless communications device in identifying a distributed content item 132 through content item identifying data 152 to generate a content item request 114.
In operation, wireless communication device 110 may receive a content item 132 signal distributed by first service provider 130. In such an aspect, the first service provider may: broadcast, multicast, and/or unicast content item 132. In one aspect, distributed content may include data (e.g. FM RDS data) associated with the content. Further, in such an aspect, the wireless communications device 110 may not be enabled to receive the accompanying FM RDS data. Further, in one aspect, first service provider 130 may distribute content item 132 using a format such as but not limited to: a frequency modulation (FM) format, an amplitude modulation (AM) format, a satellite radio format, an internet protocol (IP) format, an HD radio format, an XM radio format. Still further, in operation, content module 112 may generate a content item request 114 to obtain access to a content item 132, or a version thereof, distributed by first service provider server 130. Further, in one aspect, to assist in identifying and obtaining the requested content item 132, bookmark module 116 may couple at least one device operation identifying items 118 to the content item request. Additionally, or in the alternative, in one aspect, bookmark module 116 may receive a bookmark from another device, such second computing device, coupling the at least one device operation identifying items 118 to the content item request. In one aspect, device operation identifying items may include at least one of: an audio clip capture of the content item 132, a WCD 110 location identifier, a timestamp, a user inputted content item tag, at least a portion of metadata received with the content item 132, radio data system (RDS) information for the content item 132, or information obtained from a content guide 134 for the content item 132. In one aspect, bookmark module 116 may generate a bookmark that includes at least one of: data linked to the first content item, data defining the first content item, or a link to the first content item. In such an aspect, the link to the first content item may further include an active link to the first content item to allow the bookmark to be updated at a predetermined interval of time, such as periodically, upon a user selection, etc. In another aspect, bookmark module may generate a bookmark for content guide 134. In one aspect, upon generating content item request 114, wireless communications device 110 may transmit the content item request 114 to second service provider server 140 via network 120. In one aspect, For example, the request may be transmitted over a network using a protocol such as: CDMA, WCDMA, TDMA, TD-SCDMA, UMTS, IP GSM, LTE, WiMax, WiFi, UMB, EV-DO, etc.
Further, in operation, second service provider server 140 may receive content item request 114 coupled to bookmark information. Second service provider server 140 may be communicatively coupled to first service provider server 130 via a wired or wireless connection 145. As such, in one aspect, second service provider server 140 may process content item request 114 and any device operation identifying items to determine the content item 132 requested in content item request 114. For example, content item 132 may include but is not limited to any of: music, pictures, talk shows, blogs, contests, interactive voice response (IVR) calls, news articles, videos, wallpaper, etc. or any combination thereof. Thereafter, second service provider server 140 may attempt to obtain the identified content item 132. In one aspect, if the content item 132 may be obtained, then a version of content item 132 may be transmitted to wireless communications device. In such an aspect, the audio content item may be obtained with a format such as but not limited to: a .wav file format, or an .aac file format, or a .qcp file format, a MP3 file format, etc. Further, a visual content item, such as a picture, wallpaper, etc. may be obtained with a format such as but not limited to: a jpeg format, a .gif format, a .tiff format, a .bmp format etc. Thereafter, the obtained content item may be transmitted to wireless communications device 110 for storage, access, etc.

FIG. 2 illustrates various methodologies in accordance with the claimed subject matter. While, for purposes of simplicity of explanation, the methodologies are shown and described as a series of acts, it is to be understood and appreciated that the claimed subject matter is not limited by the order of acts, as some acts may occur in different orders and/or concurrently with other acts from that shown and described herein. For example, those skilled in the art will understand and appreciate that a methodology could alternatively be represented as a series of interrelated states or events, such as in a state diagram. Moreover, not all illustrated acts may be required to implement a methodology in accordance with the claimed subject matter. Additionally, it should be further appreciated that the methodologies disclosed hereinafter and throughout this specification are capable of being stored on an article of manufacture to facilitate transporting and transferring such methodologies to computers. The term article of manufacture, as used herein, is intended to encompass a computer program accessible from any computer-readable device, carrier, or media.
Referring to FIG. 2, at reference numeral 202, a content item, distributed by a first service provider, may be received. In one aspect, the content item may be distributed using a format such as: a frequency modulation (FM) format, an amplitude modulation (AM) format, a satellite radio format, an internet protocol (IP) format, etc. For example, a user may hear a song transmitted from an FM radio station. In such an exemplary aspect, the user may be listening to the radio through the wireless device, the user may be listening to the radio through a device communicatively coupled to the wireless device, and/or the user may be listening to the radio through a device which is not communicatively coupled to the wireless device, but where the wireless device is accessible to the user. In one aspect, at reference numeral 203, a request may be received to obtain the content item distributed by the first service provider. For example, if a user is listening on the wireless device, a prompt may be present and selected which allows the user to request that the song be obtained. In another example, if the user is listening to a second device communicatively coupled to the wireless communications device, the user may make a selection on the second device to request that the song be obtained and such a request may be communicated to the wireless communication device. In still another example, a user a make a selection through a wireless device which is not operable to receive a signal from the first service provider. In such an exemplary aspect, the wireless communications device may use a pseudo-radio application, or the like, to allow the user to make a selection and to further obtain sufficient information to allow the wireless device to subsequently identify the requested content item.
At reference numeral 204, a determination is made as to whether the content from the first service provider was distributed via a radio format, such as FM, AM, satellite radio, etc., or if the content was streamed via an IP format. Upon a determination that the content was distributed with an IP format, then at reference numeral 206, a bookmark may be generated from contextual information associated with the streamed and requested content item. In one example, the streamed content may include contextual data coupled to each content item. In another example, a content guide may be obtained which provides contextual information for at least a portion of content items distributed by the first service provider. In one aspect, additional user and/or wireless communications device information may be added to the bookmark to further identify the requested content item, the user, and/or the device. For example, device operation identifying data, such as but not limited to: an audio clip capture of a content item, a WCD location identifier, a timestamp, a user inputted content item tag, at least a portion of metadata received with a content item, radio data system (RDS) information for a content item, or information obtained from a content guide for a content item, etc. may be obtained and added to the bookmark.
Upon a determination that the content item was distributed via a radio format, at reference numeral 208, a determination may be made as to whether the requested content item was transmitted with any accompanying contextual information to facilitate identification of the requested content item. For example, a content item may be distributed using an FM format with accompanying contextual information, such as FM RDS data, which may specifically identify the content item with which it is distributed.
Upon a determination that the content item was distributed with accompanying contextual information, such as FM RDS, at reference numeral 210, a determination is made as to whether the contextual information may be obtained. For example, the requesting wireless communications device may be FM RDS enabled or a device communicatively coupled to the wireless communications device may be FM RDS enabled thereby allowing the accompanying contextual information to be obtained. If it is determined that the accompanying contextual information may be obtained at reference numeral 210, then a bookmark is generated including the accompanying contextual information, such as described above, at reference numeral 206. In one aspect, additional user and/or wireless communications device information may be added to the bookmark to further identify the requested content item, the user, or the device.
If either the content item was not distributed with accompanying contextual information or the requesting device is unable to access any such information, then at reference numeral 212, a determination is made as to whether the wireless device is able to directly receive the distributed radio signal. For example, the wireless device may include an FM transceiver to allow access to radio stations. If it is determined that the device is radio enabled, then at reference numeral 214 a bookmark is generated at least using data associated with the received radio signal. For example, the bookmark may include information such as: the radio frequency to which the device is tuned, location identifying information, a timestamp, a user inputted content item tag, at least a portion of metadata received with a content item, etc. By contrast, if at reference numeral 212 it is determined the device is not radio enabled, then at reference numeral 216, a bookmark may be generated using a pseudo-radio application, or the like, to facilitate identification of the requested content item. In one aspect, the pseudo-radio application may obtain the frequency from which the requested content item was distributed. For example, the user may input the frequency into the pseudo-radio application. Further, additional device operation identifying information may be obtained to generate the bookmark, such as: an audio clip capture of a content item, a WCD location identifier, a timestamp, a user inputted content item tag.
At reference numeral 218, the generated bookmark may be transmitted to a service provider to facilitate obtaining the requested content item. In one aspect, the transmission may be processed over a network using a protocol such as: CDMA, WCDMA, TDMA, TD-SCDMA, UMTS, IP, etc. In one aspect, the request may be transmitted to a service provider different from the service provider that distributed the requested content item. In another aspect, the request may be transmitted to the same service provider that distributed the requested content item.
With reference to FIGS. 3A, 3B, 3C, 3D and 3E, operation of the subject matter depicted in FIG. 1 in the form of a message sequence diagram is illustrated. Specifically, with reference to FIG. 3A, a message sequence diagram for acquiring a content item distributed by a first service provider with no additional contextual information is illustrated. With reference to FIG. 3B, a message sequence diagram for acquiring a content item distributed by a first service provider with no additional contextual information to a device which is not enabled to directly receive the distributed content item is illustrated. With reference to FIG. 3C, a message sequence diagram for acquiring a content item distributed by a first service provider through a second service provider is illustrated. With reference to FIG. 3D, a message sequence diagram for acquiring a content item distributed by a first service provider to a device which is not enabled to directly receive the distributed content item through use of a secondary intermediary device is illustrated.
Generally, a content distribution system 300 may include first service provider 302, a second service provider 304 and a wireless communications device (WCD) 306. In one aspect, the first and second service providers may be operated as a single service provider. In another aspect, the first service provider and second service provider may be separately operated and/or controlled. With respect to FIGS. 3A-3D, sequence steps which are similar between depicted aspects are numbered accordingly and any description accompanying the first reference to the sequence step number may be similar to subsequent usage. As such, description is provided for only the first usage of a sequence step.
Returning to FIG. 3A, at sequence step 308, first service provider 302, may synchronize content information, such as content distribution schedules with second service provider 304. In one aspect, such synchronization may occur in real time, periodically, or upon request. For example, first service provider 304 may provider a content distribution schedule for twenty four (24) hours worth of content to second service provider 304 at a predefined time each day. At sequence step 310, first service provider 302 distributes content. In the depicted aspect, the content is received by WCD 306. In one aspect, first service provider may broadcast, multicast, or unicast content using a format such as: a frequency modulation (FM) format, an amplitude modulation (AM) format, a satellite radio format, an internet protocol (IP) format, etc.
At sequence step 312, a selection is made on WCD 306 to request to obtain the content item distributed by first service provider 302. Further, such a selection includes generating a bookmark which may include sufficient information to identify the distributed content item. In one aspect, such device identifying information may include: an audio clip capture of a content item, a WCD location identifier, a timestamp, a user inputted content item tag, at least a portion of metadata received with a content item, radio data system (RDS) information for a content item, information obtained from a content guide for a content item, etc.
At sequence step 314, the request including the generated bookmark is transmitted to second service provider 304. In one aspect, WCD 303 may transmit using a protocol such as: CDMA, WCDMA, TDMA, TD-SCDMA, UMTS, IP, etc. At sequence step 316, second service provider 304 processes the request including the accompanying bookmark from WCD 306 along with synchronize content information received from first service provider 304 to identify and obtain the requested content item. In one aspect, the content item may be obtained in a format such as: a .wav file format, an .aac file format, a .qcp file format, a MP3 file format, etc. In one aspect, if second service provider 304 is unable to locate the requested content item, possible alternative content item selections may be obtained. In such an aspect, content from a similar a genre, an artist name, or an album name, etc. may be presented to the user as possible alternatives. At sequence step 318, the obtained content item is transmitted to WCD 306. In one aspect, the obtained content item may be stored on WCD 306 for subsequent access. As such, WCD 306 is able to obtain a content item from second service provider 304 which was distributed by first service provider 302 through information associated with WCD 306. By way of example and not limitation, a user may listen to a song on FM radio associated with a mobile device 306. If the user selects to obtain the song, the user can download the music file (e.g. an MP3 file) of the same song by having the mobile device 306 send information such as the FM frequency number and timestamp to a Content Server (e.g. second service provider 304). The Content Server may use information obtainable for the selected song on the particular FM radio station based on a program schedule. As such, upon receiving the request from the mobile device 306, the Content Server may fetch the song name from the program schedule, search for the song name in a Content Database, fetch the music file (e.g. an MP3 file), and send the fetched file to the mobile device 306.
Turning to FIG. 3B, as described above, at sequence step 308, first service provider 302, may synchronize content information, such as content distribution schedules with second service provider 304. At sequence step 320, first service provider 302 distributes content. In the depicted aspect, the content is received by secondary device 305. In one aspect, secondary device 305 may include a radio player, such as a car stereo, that is accessible to a user. At sequence step 322, upon hearing a content item distributed by first service provider 302 and accessed by secondary device 305, a user may make a selection on WCD 306 to obtain the distributed content item. In one aspect, WCD 306 may include a pseudo-radio application, or the like, which allows a user to select to obtain a content item which is distributed by first service provider. In such an aspect, the pseudo-radio application may generate a bookmark which includes information from the user and/or WCD 306 to sufficiently identify the requested content item. Thereafter, WCD 306 may request the content item from second service provider 304, and sequence steps 314, 316 and 318 may be performed as described above. By way of example and not limitation, a user may listen to a song, although the user isn't necessarily listening to the song through a mobile device. In such an instance, even when a user is listening to a secondary device, such as an FM radio on the car stereo etc., the user can still user can download the music file (e.g. an MP3 file) for the music track of the same song by having a mobile application send content identifying information, such as FM frequency number and timestamp to a Content Server (e.g. second service provider 304). The Content Server may use information obtainable for the selected song on the particular FM radio station based on a program schedule. As such, upon receiving the request from the mobile device 306, the Content Server may fetch the song name from the program schedule, search for the song name in a Content Database, fetch the music file (e.g. an MP3 file), and send the fetched file to the mobile device 306.
Turning now to FIG. 3C, at sequence step 324, at least a content distribution schedule, such as a content guide, is provided from first service provider 302 to second service provider 304. In one aspect, the content distribution schedule describes content distributed by first service provider 302 via a radio transmission. Further, in the depicted aspect, communication to second service provider 304 may include content provided by first service provider 302 for distribution from second service provider 304 via an IP format, such as with a streaming radio signal. At sequence step 326, second service provider 304 distributes content. In one aspect, the signal includes contextual information identifying the content being distributed. For example, a streaming radio signal may include FM RDS data, metadata, etc. identifying the distributed content item. At sequence step 328, a user may make a selection on WCD 306 to obtain the distributed content item. In one aspect, WCD 306 may generate a bookmark to identify the requested content item. For example, WCD 306 may use contextual information accompanying the distributed content item to identify the content item. In one aspect, additional user and/or WCD 306 information may be added to the bookmark to further identify the requested content item, the user, and/or the device. Thereafter, WCD 306 may request the content item from second service provider 304, and sequence steps 314, 316 and 318 may be performed as described above. By way of example and not limitation, a user may access a program guide on the mobile device which was downloaded over the air (OTA). The user may schedule an automatic recording, downloading, reminder, etc. of a particular program, event etc. through accessing the program guide. As such, the mobile device may perform one or more selected tasks, such as: download previously distributed programs; purchase content such as songs from a Content Server Content Database and/or Operator Catalogue, download podcasts audio files, video files, photos etc., get a reminder on the handset when a particular program is scheduled, etc.
Turning now to FIG. 3D, as described above, at sequence step 308, first service provider 302, may synchronize content information, such as content distribution schedules with second service provider 304. At sequence step 330, first service provider 302 distributes content. In the depicted aspect, the content may be transmitted with accompanying contextual information, such as FM RDS data, may be received by secondary device 305. In one aspect, secondary device 305 may include a personal navigation device (PND), etc. that is accessible to a user. Further, in the depicted example, secondary device 305 may be enabled to receive contextual information that may accompany the distribution of content from first service provider 302. For example, a PND may be FM RDS enabled and may receive FM RDS data accompanying the transmission of a song from a radio station. As such, even if WCD is not FM RDS enabled, a user may be able to obtain the FM RDS data that is received by an accompanying secondary device, such as a PND. At sequence step 332, a user may request to obtain the distributed content item. In the depicted aspect, the request may be made to secondary device 305. Additionally or in the alternative, a selection may be made to WCD 306 which may be communicated to secondary device 305 for further processing. Furthermore, secondary device 305 may identify the requested content item through contextual information accompanying the distributed content item to identify the content item. Further, additional user and/or secondary device 305 information may be obtained to the bookmark to further identify the requested content item, the user, and/or the secondary device. At sequence step 334, the user selection may be transmitted to WCD 306. In one aspect, such a transmission may be performed either through a wired or wireless connection. For example, secondary device 305 may communicate with WCD 306 over the air using an applicable transmission protocol such as but not limited to, WiFi, Bluetooth, etc. Further, the contextual information provided to the WCD may include a timestamp, FM station number, etc. At sequence step 336, WCD may generate a bookmark to identify the requested content item. In another aspect, said bookmark may be generated by and transmitted from secondary device 305. In one aspect, additional user and/or WCD 306 information may be added to the bookmark to further identify the requested content item, the user, and/or the device. Thereafter, WCD 306 may request the content item from second service provider 304, and sequence steps 314, 316 and 318 may be performed as described above.
Turning now to FIG. 3E, at sequence step 338, first service provider 302 distributes content to WCD 306. At sequence step 340, an application on WCD 306 may be launched and to receive distributed content. For example, when the distributed content is a FM broadcast with audio only, an application may launch on WCD 306 and tune to the FM broadcast. At sequence step 342, based at least on information processed from the received signal, WCD 306 transmits a request for additional data associated with the received content item, the first service provider, etc. Continuing the above example, the additional data may include possible content items available for download, storage, playing, etc., displays associated with the distributed content, the first service provider, additional content, etc.
At sequence step 344, a server, etc., associated with at least the first service provider may fetch the requested additional content items. For example, a server associated with at least first service provider 302 may fetch program schedule data for various FM broadcast stations. In one aspect, the server may be associated with only the first service provider 302. In another aspect, the server may be shared and/or may communicate with multiple service providers. For example, an FM station may offer access to content via one or more servers (e.g. a web servers) hosted by the FM station and/or the one or more servers may be hosted by another station, a third party, etc., that may aggregate such content from various FM stations and offer such aggregated content to a WCD. Further, the fetched data may be parsed and/or searched for corresponding music, pictures, talk shows, blogs, contests, interactive voice response (IVR) calls, news articles, videos, wallpaper, etc. in a database.
Still further, at least a portion of such fetched content may be stored and made available to WCD 306 as requested at sequence step 342. In one aspect, the request may provide appropriate request/response contents for content, such as HTTP request/response commands. In one aspect, at sequence step 344, fetched content may be further processed to format the content appropriately for WCD 306. At sequence step 346, requested additional content may be transmitted to WCD 306. In one aspect, the request and/or transmission may be made using formats such as, but not limited to, XML, JSON or other similar data exchange languages. As such, for example, if a new FM station is established at a future date, such a station may provide content to a WCD using one of the predefined described formats without any need to update and/or upgrade the WCD. In another aspect, any request and/or transmission between first service provider 302, WCD 306 and/or any associated server may use an SMS, MMS, EMS, etc. format. As such, for example, while listening to a particular FM station on a WCD, a user may receive content offered by that particular FM station which may or may not be related to the content to which a user is currently listening.
In one aspect, WCD 306 may additionally receive distributed content from another service provider, such as one or more additional radio stations and/or one or more servers. In such an aspect, sequence steps 338 through 346 may be performed with respect to the each of the one or more radio stations to which WCD 306 may be tuned.

Referring to FIG. 8, a multiple access wireless communication system according to one aspect is illustrated. An access point 800 (AP) includes multiple antenna groups, one including 804 and 806, another including 808 and 810, and an additional including 812 and 814. In FIG. 8, only two antennas are shown for each antenna group, however, more or fewer antennas may be utilized for each antenna group. Access terminal 816 (AT) is in communication with antennas 812 and 814, where antennas 812 and 814 transmit information to access terminal 816 over forward link 820 and receive information from access terminal 816 over reverse link 818. Access terminal 822 is in communication with antennas 806 and 808, where antennas 806 and 808 transmit information to access terminal 822 over forward link 826 and receive information from access terminal 822 over reverse link 824. In a FDD system, communication links 818, 820, 824 and 826 may use different frequency for communication. For example, forward link 820 may use a different frequency then that used by reverse link 818.
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 aspect, antenna groups each are designed to communicate to access terminals in a sector, of the areas covered by access point 800.
In communication over forward links 820 and 826, the transmitting antennas of access point 800 utilize beamforming in order to improve the signal-to-noise ratio of forward links for the different access terminals 816 and 824. 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.
An access point may be a fixed station used for communicating with the terminals and may also be referred to as a Node B or some other terminology. An access terminal may also be called user equipment (UE), a wireless communication device, terminal, or some other terminology.
Referring to FIG. 9, a block diagram of an aspect of a transmitter system 910 (also known as the access point) and a receiver system 950 (also known as access terminal) in a MIMO system 900 is illustrated. At the transmitter system 910, traffic data for a number of data streams is provided from a data source 912 to a transmit (TX) data processor 914.
In an aspect, each data stream is transmitted over a respective transmit antenna. TX data processor 914 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 may 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 may 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., BPSK, 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 may be determined by instructions performed by processor 930.
The modulation symbols for all data streams are then provided to a TX MIMO processor 920, which may further process the modulation symbols (e.g., for OFDM). TX MIMO processor 920 then provides NT modulation symbol streams to NT transmitters (TMTR) 922a through 922t. In certain aspects, TX MIMO processor 920 applies beamforming weights to the symbols of the data streams and to the antenna from which the symbol is being transmitted.
Each transmitter 922 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. NT modulated signals from transmitters 922a through 922t are then transmitted from NT antennas 924a through 924t, respectively.
At receiver system 950, the transmitted modulated signals are received by NR antennas 952a through 952r and the received signal from each antenna 952 is provided to a respective receiver (RCVR) 954a through 954r. Each receiver 954 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 960 then receives and processes the NR received symbol streams from NR receivers 954 based on a particular receiver processing technique to provide NT “detected” symbol streams. The RX data processor 960 then demodulates, deinterleaves, and decodes each detected symbol stream to recover the traffic data for the data stream. The processing by RX data processor 960 is complementary to that performed by TX MIMO processor 920 and TX data processor 914 at transmitter system 910.
A processor 970 periodically determines which pre-coding matrix to use (discussed below). Processor 970 formulates a reverse link message comprising a matrix index portion and a rank value portion.
The reverse link message may 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 938, which also receives traffic data for a number of data streams from a data source 936, modulated by a modulator 980, conditioned by transmitters 954a through 954r, and transmitted back to transmitter system 910.
At transmitter system 910, the modulated signals from receiver system 950 are received by antennas 924, conditioned by receivers 922, demodulated by a demodulator 940, and processed by a RX data processor 942 to extract the reserve link message transmitted by the receiver system 950. Processor 930 then determines which pre-coding matrix to use for determining the beamforming weights then processes the extracted message.
