Sep 8, 2017 - AT&T
Various embodiments disclosed herein provide for reduced overhead signaling when a user equipment device is being configured with multiple bandwidth parts for downlink transmission. When a user equipment device is being configured with multiple bandwidth parts (channels on an aggregate carrier), the signaling that indicates the codebook subset restriction bit map, rank restriction bit map, and beam restriction bit map needs to be repeated for each bandwidth part. Often however, the restriction bit maps are repeated in the bandwidth parts, and so overhead can be reduced by encoding a confirmation bit in each bandwidth part, such that if the confirmation bit is set to “1”, the user equipment device can know to apply the restriction bit map from the primary bandwidth part to the secondary bandwidth part, without having to encode the secondary bandwidth part restriction bit map.
The present application relates generally to the field of mobile communication and, more specifically, to reducing overhead in higher layer signaling in a next generation wireless communications network.
To meet the huge demand for data centric applications, Third Generation Partnership Project (3GPP) systems and systems that employ one or more aspects of the specifications of the Fourth Generation (4G) standard for wireless communications will be extended to a Fifth Generation (5G) standard for wireless communications. Unique challenges exist to provide levels of service associated with forthcoming 5G and other next generation network standards.

FIG. 1 illustrates an example wireless communication system 100 in accordance with various aspects and embodiments of the subject disclosure. In one or more embodiments, system 100 can comprise one or more user equipment UEs 104 and 102, which can have one or more antenna panels having vertical and horizontal elements. A UE 102 can be a mobile device such as a cellular phone, a smartphone, a tablet computer, a wearable device, a virtual reality (VR) device, a heads-up display (HUD) device, a smart car, a machine-type communication (MTC) device, and the like. User equipment UE 102 can also comprise IOT devices that communicate wirelessly. In various embodiments, system 100 is or comprises a wireless communication network serviced by one or more wireless communication network providers. In example embodiments, a UE 102 can be communicatively coupled to the wireless communication network via a network node 106.
The non-limiting term network node (or radio network node) is used herein to refer to any type of network node serving a UE 102 and UE 104 and/or connected to other network node, network element, or another network node from which the UE 102 or 104 can receive a radio signal. Network nodes can also have multiple antennas for performing various transmission operations (e.g., MIMO operations). A network node can have a cabinet and other protected enclosures, an antenna mast, and actual antennas. Network nodes can serve several cells, also called sectors, depending on the configuration and type of antenna. Examples of network nodes (e.g., network node 106) can comprise but are not limited to: NodeB devices, base station (BS) devices, access point (AP) devices, and radio access network (RAN) devices. The network node 106 can also comprise multi-standard radio (MSR) radio node devices, including but not limited to: an MSR BS, an eNode B, a network controller, a radio network controller (RNC), a base station controller (BSC), a relay, a donor node controlling relay, a base transceiver station (BTS), a transmission point, a transmission node, an RRU, an RRH, nodes in distributed antenna system (DAS), and the like. In 5G terminology, the node 106 can be referred to as a gNodeB device.
Wireless communication system 100 can employ various cellular technologies and modulation schemes to facilitate wireless radio communications between devices (e.g., the UE 102 and 104 and the network node 106). For example, system 100 can operate in accordance with a UMTS, long term evolution (LTE), high speed packet access (HSPA), code division multiple access (CDMA), time division multiple access (TDMA), frequency division multiple access (FDMA), multi-carrier code division multiple access (MC-CDMA), single-carrier code division multiple access (SC-CDMA), single-carrier FDMA (SC-FDMA), OFDM, (DFT)-spread OFDM or SC-FDMA)), FBMC, ZT DFT-s-OFDM, GFDM, UFMC, UW DFT-Spread-OFDM, UW-OFDM, CP-OFDM, resource-block-filtered OFDM, and UFMC. However, various features and functionalities of system 100 are particularly described wherein the devices (e.g., the UEs 102 and 104 and the network device 106) of system 100 are configured to communicate wireless signals using one or more multi carrier modulation schemes, wherein data symbols can be transmitted simultaneously over multiple frequency subcarriers (e.g., OFDM, CP-OFDM, DFT-spread OFMD, UFMC, FMBC, etc.).
In an embodiment, network node can configure UEs 102 and 104 via a radio resource control (RRC) signaling, which can be higher layer signaling. The RRC signaling can configure the user and control plane according to the network status. The type of configuration can be based on the number of antennas on a transmitter of the network node 106 as well as other considerations. The information signaling during the RRC signaling can include Pre-coding Matrix Indicator (PMI) Rank Indicator (RI), and beam index estimation. In order to reduce overhead, and more efficiently manage resources, the network node 106 can configure restriction bit maps that limit the amount of information transmitted. According to 3GPP standards, a UE is restricted to report PMI, RI, and beam index estimation within a precoder codebook subset specified by a bitmap parameter codebookSubsetRestriction (for the case of PMI) configured by higher layer signaling. For a specific precoder codebook associated with the number of antenna ports, the bitmap can specify all possible precoder codebook subsets from which the UE should assume the network node 106 may be using when transmitting to the UE. For example, if the number of codebook elements defined for 2 Tx antenna ports is equal to 6+2. i.e. 6 precoding vectors for rank is equal to one and 2 precoding matrices for rank is equal to 2. Then the codebooksubset restriction bit map is equal to 8. Then the network can send a bit map equal to 8 and setting those bits so that the UE should assume those precoder elements in the CSI reporting. Similarly the codebook subset restriction is defined for 4 transmit and 8 transmit antenna ports.
The resulting number of bits for configured number of antenna ports is given in Table 1. The bitmap forms the bit sequence aAc-1, . . . , a3, a2, a1, a0 where a0 is the LSB and aAc-1 is the MSB and where a bit value of zero indicates that the PMI and RI reporting is not allowed to correspond to precoder(s) associated with the bit.
Number of bits Ac
Number of Length of antenna ports bit map
2 4 4 64 8 512
Similarly, the network can send rank restriction bit map equal to the number of antenna ports so that the UE assumes the network will schedule those ranks only for PDSCH transmission when it reports CSI. Table 2 shows bit map length for each antenna ports. Table 2 shows the rank restriction bit map for each antenna port. The same principle can be applied for beam restriction.
As can be seen in Tables 1 and 2, the size of the bit maps for the codebook subset restriction, rank restriction and beam restriction can be large, and consume a large amount of overhead if being signaled to the UEs 102 and 104 during each RRC signaling period.
In 5G systems furthermore, multiple channels may be included in an aggregate carrier channel. For instance, the component carrier bandwidth can be 400 MHz, and a UE may only use a subset of that bandwidth. Hence, for 5G systems, a UE can be configured with one or more carrier bandwidth parts in the downlink with a subset of carrier bandwidth parts being active at a given time. The UE is not expected to receive downlink control information or data outside an active bandwidth part. A UE can be configured with one or more carrier bandwidth parts in the uplink with a subset of carrier bandwidth parts being active at a given time. The UE may also not transmit uplink control information or uplink data outside an active bandwidth part. Each of the channels, or bandwidth parts on the aggregate carrier can be configured using a separate restriction bit map.
Often times however, the restriction bit maps, whether it is a codebook subset restriction bit map, rank restriction bit map, or beam restriction bit map, will be the same for multiple bandwidth parts. In order to reduce overhead, a confirmation bit can be encoded in the RRC signaling for each bandwidth part, where if the confirmation bit has a value of 1, the UE can use the restriction bit map from the primary bandwidth part for the secondary bandwidth part, and then the restriction bit map will not need to be transmitted in the secondary bandwidth part. In an embodiment, if there are four bandwidth parts, and they all have the same restriction bit maps, then only one restriction bit map will be transmitted during RRC signaling for the primary bandwidth part, while 3 confirmation bits can be encoded in the other bandwidth parts to indicate to the UE to use the primary bandwidth part's restriction bit map.
It is to be appreciated that while reference is made of this disclosure applying to downlink (e.g., base station to UE) configuration, in other embodiments, the techniques disclosed herein can apply to uplink communications as well.
Turning now to FIG. 2, illustrated is an example block diagram of a message sequence chart 200 in accordance with various aspects and embodiments of the subject disclosure.
The message sequence chart 200 can be between a gNodeB 202 and a UE 204 within the gNodeB 202 cell. The gNodeB 202 can configure the UE 204 during RRC setup 206 and set the PMI, RI, and beam index estimation to establish and facilitate the control plane and user plane transmissions. The RRC signaling can be part of any setup, confirm or reconfiguration message, for example, radio bearer set up, active set update message, cell update confirm, radio bearer reconfiguration, physical channel reconfiguration or transport channel reconfiguration. The gNodeB 202 can send a reference signal 206 (CSI-RS) to the UE 204. The reference signal 208 can be a pilot signal that is cellular specific or UE specific and is used by the UE 204 to acquire channel-state information (CSI) and beam specific information (beam RSRP). In 5G wireless networks, the CSI-RS is UE specific so it can have a significantly lower time/frequency density. The reference signal 208 can also include demodulation reference signals that are intended to be used by terminals for channel estimation for data channel. The label “UE-specific” relates to the fact that each demodulation reference signal is intended for channel estimation by a single terminal. That specific reference signal is then only transmitted within the resource blocks assigned for data traffic channel transmission to that terminal.
The UE 204 can send back a feedback signal 210 that comprises channel state information determined from the reference signal(s) 208. The channel state information can include a channel quality indicator, precoding matrix, rank information, and resource indicator (beam indicator). The rank indicator can indicate the number of layers that are supportable in transmissions between the gNodeB 202 and the UE 204. For instance, when the SINR is low, due to a function of low power, a large distance between the devices, path loss, and/or other interference, the rank indicator can be 1, indicating that only one layer can be supported. In other embodiments, when the SINR is high, the Rank can be two or four or higher, indicating that multiple data layers can be supported, allowing MIMO communications between the gNodeB 202 and the UE 204. From this channel state information and based on other scheduler inputs, the gNodeB 202 sends a downlink control channel 212 where the scheduling information is sent. Once the UE 204 decodes this downlink control channel 212, actual data transfer 214 takes place between the gNodeB 202 and the UE 204.
Turning now to FIG. 3, illustrated is an example block diagram 300 of bandwidth parts and confirmation bits in accordance with various aspects and embodiments of the subject disclosure.
In an embodiment, a component carrier 302 can have multiple bandwidth parts, or channels 304, 306, 308, and 310. In an embodiment, the configuration for bandwidth parts 304, 306, and 308 are the same, e.g., each uses a restriction bit map A. Instead of resending the restriction bit map A to each of bandwidth parts 306 and 308, the system can encode confirmation bits 312 and 314 to bandwidth parts 306 and 308 that indicate to the receiver or UE device that the same bit map A should be used to configure the UE for bandwidth parts 306 and 308. The lack of a confirmation bit associated with bandwidth part 310 can indicate that a new bit map (e.g., bit map B) has been encoded to configure the UE for bandwidth part 310. In other embodiments, bandwidth part 310 can have a confirmation bit set to a null value (e.g., “0”) to indicate that a new restriction bit map has been sent.
It is to be appreciated that while FIG. 3, displays four bandwidth parts, in other embodiments, the component carrier 302 can include a different number of bandwidth parts, or channels.
In another embodiment, instead of sending a confirmation bit with each bandwidth part that has a matching restriction bit map, the network can send a new information element (IE) by higher layer using RRC signaling indicating whether all bandwidth parts of the carrier operation will use the same restriction bit map as that of the primary bandwidth part of that carrier already indicated or configured for the primary bandwidth part indicated by RRC signaling. Upon receiving the information element, the UE decodes this information and interprets if this bit is set to 1, then for example in four cell operation it means that the restriction bit map for each of the bandwidth parts are all equal to the primary bandwidth part and due to this, the bandwidth parts will not report channel state parameters (CQI, PMI, RI) using the precoding elements which are not set by the restriction bitmap. Note that precoding subset restriction bits are set to “1” in the primary bandwidth part.
In another embodiment, the network can send a new information element with the confirmation bit set to “0” for a bandwidth part of a component carrier and sends a new codebook subset restriction bitmap. In this case, when the UE receives the information element, the UE can decode and when it identifies that the confirmation bit is equal to 0, it erases the previous codebook subset restriction bit map and sets the bit map according to the new configuration. The channel state information parameters are reported according to the new bit map it received by RRC signaling.
In another embodiment, the network can send a new restriction bit map without sending the confirmation bit. Note that in these cases the network needs to send the bitmap which is different compared to that of primary bandwidth part's bitmap. In another embodiment, the network and the UE are configured such that if the network doesn't send either a confirmation bit or a new restriction bit map for each BWP, then it is implicitly understood by the UE that it will use the primary bandwidth part configuration (bit map) or the cell or carrier bit map.
Turning now to FIG. 4, illustrated is an example block diagram 400 of bandwidth parts and a confirmation bit map in accordance with various aspects and embodiments of the subject disclosure.
In an embodiment, a confirmation bit map 412 can be sent via RRC signaling indicating which bandwidth parts 404, 406, 408, and 410 are grouped together, or have similar restriction bit maps. For instance, of the component carrier 402, bandwidth parts 404 and 408 can be similar, each using the same restriction bit map A, while bandwidth parts 406 and 410 can be similar, using restriction bit map B. The confirmation bit map 412 can be one or more bits mapping the relationship of the restriction bit maps, such that for each grouping, only one restriction bit map needs to be sent (e.g., in FIG. 4, one restriction bit map A with bandwidth part 404 and one restriction bit map B with bandwidth part 406.).
In an embodiment, the network can send the new IE confirmation bit map 412 to indicate to the UE that the restriction bit map for a set or a subset of bandwidth parts is equal. In case the UE support multiple BWPs in 2 bands, the UE indicates to the network the exact carrier/band combinations in “UE radio access capability”. The network can indicate to the UE the specific restriction bitmap for the bandwidth part in that band, by indicating which bandwidth part in a specific band will have the same codebook subset restriction, by this the restriction bitmap will be band specific. For example, in case of four bandwidth part operations in FIG. 4, the confirmation bit map 412 can be sent from the network which indicates the various subsets of operation.
In an embodiment, if the network sends a bit map equal to 001, that can mean that the restriction bit map of bandwidth part of 3 is equal to that bandwidth part 1, while the codebook subset restriction for the third bandwidth part 408 is equal to the restriction bit map for the fourth bandwidth part 410 (this could be indicated in another bit map option, for example 101), as shown in the Table 3 below:
Option bitmap Indication clarification
1 000 CBSR of C2 = CBSR of C1 2 001 CBSR of C3 = CBSR of C1 3 010 CBSR of C4 = CBSR of C1 4 011 CBSR of C3 = CBSR of C2 5 100 CBSR of C4 = CBSR of C3 6 101 CBSR of C3 = CBSR of C2 = CBSR of C1 7 110 CBSR of C4 = CBSR of C3 = CBSR of C1 8 111 CBSR of C4 = CBSR of C3 = CBSR of C2 Note: CBSR—codebook subset restriction, C1 Primary BWP, C2—Secondary BWP, C3—3rd BWP, C4—4th BWP
As an example embodiment Table 3, for option 1, where the confirmation bit map 412 is coded “000”, that can indicate that the codebook subset restriction bit map for bandwidth part two (e.g., 406) is the same as that of bandwidth part one (e.g., 404). Table 3 shows how 3 bits can be used to show all the different combinations of groupings for component carriers with four bandwidth parts or channels. Table 3 references codebook subset restriction bit maps, but the same principles can be applied to beam and rank restriction bit maps. It is also to be appreciated that in other configurations, the confirmation bit maps can have different codings for different groupings.
It is also to be appreciated that in other embodiments, the component carrier can have a plurality of confirmation bit maps, with respective confirmation bit maps for each of codebook subset restriction bit maps, rank restriction bit maps, and beam restriction bit maps. Each of the bandwidth parts in FIG. 3, can also have respective confirmation bits for each of the types of restriction bit maps as well.
Turning now to FIG. 5, illustrated is an example block diagram 500 of a base station device system 502 in accordance with various aspects and embodiments of the subject disclosure.
The base station device 502 can have an RRC component 506 that determines the codebook subset restriction bit map, rank restriction bit map, and beam restriction bit maps to configure the UE with. A grouping component 510 can determine which bandwidth parts of the component carrier are similar, and an encoding component 508 can encode confirmation bits to indicate to the UE which of the bandwidth parts are similar to avoid having to send multiple repetitive restriction bit maps. The transceiver component 504 can transmit the RRC signaling to the user equipment device.
Turning now to FIG. 6, illustrated is an example block diagram 600 of a user equipment device system 602 in accordance with various aspects and embodiments of the subject disclosure.
A transceiver component 604 receives the RRC signaling from the base station device, and an RRC component 608 applies the restriction bit maps from the RRC signaling for the primary bandwidth part. The confirmation component 606 checks to see if there is a confirmation bit in the secondary and other bandwidth parts, and if there is, the RRC component 608 applies the restriction map received for the first bandwidth part to the other bandwidth parts with the confirmation bit.

At 806, the method comprises encoding, by the transceiver device, a confirmation bit in the secondary channel indicating to a receiver device to use the first restriction bit map for transmissions via the secondary channel.
Referring now to FIG. 9, illustrated is a schematic block diagram of an example end-user device such as a user equipment) that can be a mobile device 900 capable of connecting to a network in accordance with some embodiments described herein. Although a mobile handset 900 is illustrated herein, it will be understood that other devices can be a mobile device, and that the mobile handset 900 is merely illustrated to provide context for the embodiments of the various embodiments described herein. The following discussion is intended to provide a brief, general description of an example of a suitable environment 900 in which the various embodiments can be implemented. While the description includes a general context of computer-executable instructions embodied on a machine-readable storage medium, those skilled in the art will recognize that the various embodiments also can be implemented in combination with other program modules and/or as a combination of hardware and software.
The handset 900 includes a processor 902 for controlling and processing all onboard operations and functions. A memory 904 interfaces to the processor 902 for storage of data and one or more applications 906 (e.g., a video player software, user feedback component software, etc.). Other applications can include voice recognition of predetermined voice commands that facilitate initiation of the user feedback signals. The applications 906 can be stored in the memory 904 and/or in a firmware 908, and executed by the processor 902 from either or both the memory 904 or/and the firmware 908. The firmware 908 can also store startup code for execution in initializing the handset 900. A communications component 910 interfaces to the processor 902 to facilitate wired/wireless communication with external systems, e.g., cellular networks, VoIP networks, and so on. Here, the communications component 910 can also include a suitable cellular transceiver 911 (e.g., a GSM transceiver) and/or an unlicensed transceiver 913 (e.g., Wi-Fi, WiMax) for corresponding signal communications. The handset 900 can be a device such as a cellular telephone, a PDA with mobile communications capabilities, and messaging-centric devices. The communications component 910 also facilitates communications reception from terrestrial radio networks (e.g., broadcast), digital satellite radio networks, and Internet-based radio services networks.
The handset 900 includes a display 912 for displaying text, images, video, telephony functions (e.g., a Caller ID function), setup functions, and for user input. For example, the display 912 can also be referred to as a “screen” that can accommodate the presentation of multimedia content (e.g., music metadata, messages, wallpaper, graphics, etc.). The display 912 can also display videos and can facilitate the generation, editing and sharing of video quotes. A serial I/O interface 914 is provided in communication with the processor 902 to facilitate wired and/or wireless serial communications (e.g., USB, and/or IEEE 1394) through a hardwire connection, and other serial input devices (e.g., a keyboard, keypad, and mouse). This supports updating and troubleshooting the handset 900, for example. Audio capabilities are provided with an audio I/O component 916, which can include a speaker for the output of audio signals related to, for example, indication that the user pressed the proper key or key combination to initiate the user feedback signal. The audio I/O component 916 also facilitates the input of audio signals through a microphone to record data and/or telephony voice data, and for inputting voice signals for telephone conversations.
The handset 900 can process IP data traffic through the communication component 910 to accommodate IP traffic from an IP network such as, for example, the Internet, a corporate intranet, a home network, a person area network, etc., through an ISP or broadband cable provider. Thus, VoIP traffic can be utilized by the handset 800 and IP-based multimedia content can be received in either an encoded or decoded format.
A video processing component 922 (e.g., a camera) can be provided for decoding encoded multimedia content. The video processing component 922 can aid in facilitating the generation, editing and sharing of video quotes. The handset 900 also includes a power source 924 in the form of batteries and/or an AC power subsystem, which power source 924 can interface to an external power system or charging equipment (not shown) by a power I/O component 926.
The handset 900 can also include a video component 930 for processing video content received and, for recording and transmitting video content. For example, the video component 930 can facilitate the generation, editing and sharing of video quotes. A location tracking component 932 facilitates geographically locating the handset 900. As described hereinabove, this can occur when the user initiates the feedback signal automatically or manually. A user input component 934 facilitates the user initiating the quality feedback signal. The user input component 934 can also facilitate the generation, editing and sharing of video quotes. The user input component 934 can include such conventional input device technologies such as a keypad, keyboard, mouse, stylus pen, and/or touch screen, for example.
Referring again to the applications 906, a hysteresis component 936 facilitates the analysis and processing of hysteresis data, which is utilized to determine when to associate with the access point. A software trigger component 938 can be provided that facilitates triggering of the hysteresis component 938 when the Wi-Fi transceiver 913 detects the beacon of the access point. A SIP client 940 enables the handset 900 to support SIP protocols and register the subscriber with the SIP registrar server. The applications 906 can also include a client 942 that provides at least the capability of discovery, play and store of multimedia content, for example, music.
The handset 900, as indicated above related to the communications component 810, includes an indoor network radio transceiver 913 (e.g., Wi-Fi transceiver). This function supports the indoor radio link, such as IEEE 802.11, for the dual-mode GSM handset 900. The handset 900 can accommodate at least satellite radio services through a handset that can combine wireless voice and digital radio chipsets into a single handheld device.
Referring now to FIG. 10, there is illustrated a block diagram of a computer 1000 operable to execute the functions and operations performed in the described example embodiments. For example, a network node (e.g., network node 406) may contain components as described in FIG. 10. The computer 1000 can provide networking and communication capabilities between a wired or wireless communication network and a server and/or communication device. In order to provide additional context for various aspects thereof, FIG. 10 and the following discussion are intended to provide a brief, general description of a suitable computing environment in which the various aspects of the embodiments can be implemented to facilitate the establishment of a transaction between an entity and a third party. While the description above is in the general context of computer-executable instructions that can run on one or more computers, those skilled in the art will recognize that the various embodiments also can be implemented in combination with other program modules and/or as a combination of hardware and software.
The computer 1000 further includes an internal hard disk drive (HDD) 1014 (e.g., EIDE, SATA), which internal hard disk drive 1014 can also be configured for external use in a suitable chassis (not shown), a magnetic floppy disk drive (FDD) 1016, (e.g., to read from or write to a removable diskette 1018) and an optical disk drive 1020, (e.g., reading a CD-ROM disk 1022 or, to read from or write to other high capacity optical media such as the DVD). The hard disk drive 1014, magnetic disk drive 1016 and optical disk drive 1020 can be connected to the system bus 1008 by a hard disk drive interface 1024, a magnetic disk drive interface 1026 and an optical drive interface 1028, respectively. The interface 1024 for external drive implementations includes at least one or both of Universal Serial Bus (USB) and IEEE 1394 interface technologies. Other external drive connection technologies are within contemplation of the subject embodiments.
The drives and their associated computer-readable media provide nonvolatile storage of data, data structures, computer-executable instructions, and so forth. For the computer 1000 the drives and media accommodate the storage of any data in a suitable digital format. Although the description of computer-readable media above refers to a HDD, a removable magnetic diskette, and a removable optical media such as a CD or DVD, it should be appreciated by those skilled in the art that other types of media which are readable by a computer 1000, such as zip drives, magnetic cassettes, flash memory cards, cartridges, and the like, can also be used in the example operating environment, and further, that any such media can contain computer-executable instructions for performing the methods of the disclosed embodiments.
A number of program modules can be stored in the drives and RAM 1012, including an operating system 1030, one or more application programs 1032, other program modules 1034 and program data 1036. All or portions of the operating system, applications, modules, and/or data can also be cached in the RAM 1012. It is to be appreciated that the various embodiments can be implemented with various commercially available operating systems or combinations of operating systems.
A user can enter commands and information into the computer 1000 through one or more wired/wireless input devices, e.g., a keyboard 1038 and a pointing device, such as a mouse 1040. Other input devices (not shown) may include a microphone, an IR remote control, a joystick, a game pad, a stylus pen, touch screen, or the like. These and other input devices are often connected to the processing unit 1004 through an input device interface 1042 that is coupled to the system bus 1008, but can be connected by other interfaces, such as a parallel port, an IEEE 1394 serial port, a game port, a USB port, an IR interface, etc.
The computer 1000 can operate in a networked environment using logical connections by wired and/or wireless communications to one or more remote computers, such as a remote computer(s) 1048. The remote computer(s) 1048 can be a workstation, a server computer, a router, a personal computer, portable computer, microprocessor-based entertainment device, a peer device or other common network node, and typically includes many or all of the elements described relative to the computer, although, for purposes of brevity, only a memory/storage device 1050 is illustrated. The logical connections depicted include wired/wireless connectivity to a local area network (LAN) 1052 and/or larger networks, e.g., a wide area network (WAN) 1054. Such LAN and WAN networking environments are commonplace in offices and companies, and facilitate enterprise-wide computer networks, such as intranets, all of which may connect to a global communications network, e.g., the Internet.
When used in a LAN networking environment, the computer 1000 is connected to the local network 1052 through a wired and/or wireless communication network interface or adapter 1056. The adapter 1056 may facilitate wired or wireless communication to the LAN 1052, which may also include a wireless access point disposed thereon for communicating with the wireless adapter 1056.
