Description

METHOD AND APPARATUS FOR IMPLEMENTING A

DYNAMICALLY SWITCHING DUPLEX MODE

TECHNICAL FIELD

Embodiments of the present invention relate generally to communication technology, and, more particularly, relate to a method, apparatus, and computer program product for implementing a dynamically switching duplex mode.

BACKGROUND

The modern communications era has brought about a tremendous expansion of wireline and wireless networks. Computer networks, television networks, and telephony networks are experiencing an unprecedented

technological expansion, fueled by consumer demand. Wireless and mobile networking technologies have addressed related consumer demands, while providing more flexibility and immediacy of information transfer. Additionally, significant developments have been made with respect to the devices and methods that utilize these networks.

Current and future networking technologies continue to facilitate ease of information transfer and convenience to users. In many instances, however, a trade-off exists between the desire for high quality service and compact, low-cost, high-efficiency devices. For example, many consumers seek smaller, cheaper networking devices without a reduction in the quality of the networking services those devices provide. As a result of this consumer demand, a need arises for methods and devices that help maintain the high quality of service while managing to decrease the overall cost and size of the associated devices.

SUMMARY

A key factor in providing high speed and high quality networking services in a mobile device involves reducing interference at the receiver from signals other than the signal of interest. In full duplex communications, which allow a networking device to both transmit and receive data simultaneously, the power output of the transmitter is often one of the largest contributors to interference at the receiver. As a result, most devices operating in full duplex include bulky, costly, and high power-consuming duplexer filters that block the transmitter interference from the receiver. Changing the operation of a device from full duplex to half duplex, during which a device may only either transmit or receive at a given time, would eliminate the need for the duplexer filters, and potentially other types of filters, because the transmitter could never operate simultaneously with the receiver. Accordingly, the mutually exclusive operation of the transmitter and receiver would prevent the transmitter from interfering with the receiver.

Using only half duplex, however, typically results in a significant reduction to both communication speed and quality. Various embodiments of the invention described below seek to offer solutions to these problems by providing apparatuses and methods for implementing a dynamically switching duplex mode in a device based on comparing a power ratio to a power threshold.

Example methods, example apparatuses, and example computer program products are described herein that provide for implementing a dynamically switching duplex mode. One example method may include providing for transmission of a status message comprising an indication of communication information. The example method may further include receiving a duplex message comprising a command to switch to an indicated duplex operation. The command may be based at least in part on a comparison of a power ratio and a power ratio threshold, where the indicated duplex operation is half duplex in the instance in which the power ratio is greater than the power ratio threshold and the current operation is full duplex, and where the indicated duplex operation is full duplex in the instance in which the power ratio is less than the power ratio threshold and the current operation is half duplex. In another embodiment, a computer program may be provided for executing the various operations of the example method.

An additional example embodiment is an apparatus configured to provide for implementing a dynamically switching duplex mode. The example apparatus may comprise at least one processor and at least one memory including computer program code, the at least one memory and the computer program code configured to, with the at least one processor, direct the apparatus to perform various functionality. In this regard, the example apparatus may be directed to provide for transmission of a status message comprising an indication of communication information. The example apparatus may also be directed to receive a duplex message comprising a command to switch to an indicated duplex operation. The command may be based at least in part on a comparison of a power ratio and a power ratio threshold, where the indicated duplex operation is half duplex in the instance in which the power ratio is greater than the power ratio threshold and the current operation is full duplex, and where the indicated duplex operation is full duplex in the instance in which the power ratio is less than the power ratio threshold and the current operation is half duplex.

Another example embodiment is a computer program product comprising a non-transitory memory or other non-transitory computer readable medium having computer program code stored thereon, wherein the computer program code is configured to direct an apparatus to perform various functionalities. In this regard, the program code may be configured to provide for transmission of a status message comprising an indication of communication information. The example computer program code may also be configured to receive a duplex message comprising a command to switch to an indicated duplex operation. The command may be based at least in part on a comparison of a power ratio and a power ratio threshold, where the indicated duplex operation is half duplex in the instance in which the power ratio is greater than the power ratio threshold and the current operation is full duplex, and where the indicated duplex operation is full duplex in the instance in which the power ratio is less than the power ratio threshold and the current operation is half duplex.

Another example apparatus comprises means for providing for transmission of a status message comprising an indication of communication information. The example apparatus may further comprise means for receiving a duplex message comprising a command to switch to an indicated duplex operation. The command may be based at least in part on a comparison of a power ratio and a power ratio threshold, where the indicated duplex operation is half duplex in the instance in which the power ratio is greater than the power ratio threshold and the current operation is full duplex, and where the indicated duplex operation is full duplex in the instance in which the power ratio is less than the power ratio threshold and the current operation is half duplex.

Like volatile memory 40 non-volatile memory 42 may include a cache area for temporary storage of data. The memories may store one or more software programs, instructions, pieces of information, data, and/or the like which may be used by the mobile terminal for performing functions of the mobile terminal. For example, the memories may comprise an identifier, such as an international mobile equipment identification (IMEI) code, capable of uniquely identifying the mobile terminal 10.

According to various embodiments, the communication interface 124 may further comprise the duplex switching circuitry 128. Alternatively, the duplex switching circuitry 128 may be a separate means in communication with the communication interface 124, as shown in Figure 1.

The user interface 126 may be in communication with the processor 120 to receive user input via the user interface 126 and/or to present output to a user as, for example, audible, visual, mechanical, or other output indications. The user interface 126 may include, for example, a keyboard, a mouse, a joystick, a display (e.g., a touch screen display), a microphone, a speaker, camera, accelerometer, or other input/output mechanisms. Further, the processor 120 may comprise, or be in communication with, user interface circuitry configured to control at least some functions of one or more elements of the user interface.

In embodiments wherein the duplex switching circuitry 128 is embodied separately from the processor 120, the duplex switching circuitry 128 may be in communication with the processor 120. The duplex switching circuitry 128 may further be in communication with one or more of the memory 122, communication interface 124, user interface 126, or I/O interface 130, such as via a bus. The duplex switching circuitry 128 may be configured to provide for implementing a dynamically switching duplex mode, such as to enable a terminal apparatus 102 to dynamically switch between full duplex and half duplex during operation.

The duplex switching circuitry 128 may be configured to provide for transmission of a reporting message to a network entity identifying the ability to support a dynamically switching duplex mode. The reporting message may be, for example, a control message or an information message. Alternatively, the reporting message may be included as a portion of another message. The network entity may maintain a database of devices that support the dynamically switching duplex mode. In some embodiments, sending a reporting message may be optional. For example, the network entity may already be aware of the ability of a terminal apparatus 102 to support the dynamically switching duplex mode, such as when an entry for a particular terminal apparatus 102 is already stored in the network database.

The network entity may comprise any computing device, mobile or fixed, and may be embodied as a server, desktop computer, laptop computer, mobile terminal 10, and/or the like configured to provide network side services, such as address allocation. The network entity may also be embodied as a combination of a plurality of computing devices configured to provide network side services, such as address allocation. In this regard, the network entity may be embodied, for example, as a server cluster and/or may be embodied as a distributed computing system, which may be distributed across a plurality of computing devices, such as, for example, mobile terminals. According to various embodiments, the network entity may be embodied as an access point, a base station, such as a Node B or eNode B, or the like. In one embodiment, the network entity may be embodied as a gateway of a service provider. For example, the network entity 104 may be embodied as a 3 GPP PDN Gateway, a GGSN, a WiMAX CSN Gateway, or the like. In some embodiments, the network entity may be located a single hop from the terminal apparatus 102.

In an example embodiment the network entity includes various means, such as a processor, memory, communication interface, user interface, I/O interface, and/or network-side duplex switching circuitry for performing the various functions herein described. These means of the network entity as described herein may be embodied as, for example, circuitry, hardware elements (e.g., a suitably programmed processor, combinational logic circuit, and/or the like), a computer program product comprising computer-readable program instructions (e.g., software or firmware) stored on a computer-readable medium (e.g. memory) that is executable by a suitably configured processing device (e.g., a processor), or some combination thereof.

The dynamically switching duplex mode may comprise switching back and forth between full duplex and half duplex operation dynamically. Unlike a static duplex mode where a device may be configured to operate either according to full duplex or half duplex, the dynamically switching duplex mode may provide additional flexibility by allowing the same device to switch between full duplex and half duplex during operation based at least in part on various network conditions.

The duplex switching circuitry 128 may be further configured to provide for transmission of a status message to a network entity comprising various communication information related to the terminal apparatus 102. Alternatively, the status message may be included as a portion of another message. According to certain embodiments, the communication information may comprise an indication of the received signal strength, or in particular a received signal strength indicator (RSSI). The RSSI may indicate the power of a signal received by the receiver 16. In example embodiments, the communication information may further or alternatively comprise an indication of the transmission power of the terminal apparatus 102. The transmission power may indicate the output power of the transmitter 14.

Additionally, according to various embodiments, the communication information may further comprise additional information available to the duplex switching circuitry 128. In particular, the additional information may comprise information identifying the different types of interference present, the modulation of the interference, leaked power from the transmitter, any information related to an interferer signal (e.g. an interferer signal at half or twice the duplex frequency separation), any information related to any type of interference as a whole or on a signal level or band level experienced by the terminal apparatus 102, or the like. In certain embodiments, the additional information may be included in the status message described above or may be sent in a separate message from the duplex switching circuitry 128 to the network entity.

According to additional and/or alternative embodiments, the network entity that receives the status message from the duplex switching circuitry 128 comprising communication information may already be aware of certain communication information. For example, in certain cellular networks, the RSSI and transmission power values may have previously been requested by the network entity for other purposes. In some embodiments, the network entity may command the terminal apparatus 102, processor 120, and/or duplex switching circuitry 128 to adjust the transmission output power to a specific value based on current network conditions. Accordingly, in these instances, the network entity may already be aware of the transmission output power of the terminal apparatus 102. According to various embodiments, the received signal strength and transmission power values may be used to determine a power ratio. For example, the power ratio may equal the transmission power divided by the received signal strength. In some embodiments, the power ratio may be based on received signal strength and transmission power measurements in decibels referenced to one milliwatt (dBm), in which cases the power ratio may be determined by subtracting the absolute value of the received signal strength in dBm from the absolute value of the transmission power in dBm. The power ratio may, therefore, provide an indication as to the magnitude of the transmission power in relation to the received signal strength. In various example embodiments, the power ratio may be based on alternative or additional communication information.

According to various embodiments, the power ratio may be used to determine the significance of the interference caused by the transmission power at the receiver 16. To make the determination, in some embodiments, the power ratio may be compared to a power ratio threshold. The power ratio threshold may identify the point where a terminal apparatus 102 should switch from full duplex to half duplex, or vice versa. Accordingly, a power ratio threshold may be selected such that the magnitude of transmit power interference compared to the current received signal strength is acceptable when the power ratio is less than the power ratio threshold, and vice versa. In some embodiments, separate power ratio thresholds may exist for determining when duplex operation should switch from full duplex to half duplex and determining when duplex operation should switch from half duplex to full duplex. In alternative embodiments, the same power ratio threshold may be used for both instances. In some example embodiments, a separate power ratio may be determined for each channel or frequency band.

Accordingly, in these instances, a separate power ratio threshold may be selected for each channel or frequency band. The power ratio threshold(s) may be set by the duplex switching circuitry 128, the network entity, and/or a third party.

Additionally, according to various embodiments, the power ratio threshold(s) may be selected dynamically.

According to an example embodiment, if the transmit power is relatively large in comparison to the received signal strength, the power ratio will be relatively high indicating that the amount of interference may be unacceptable. In these instances, the power ratio may be greater than the power ratio threshold thus prompting a switch from full duplex to half duplex operation. Alternatively, if the transmit power is relatively small in comparison to the received signal strength, the power ratio will be relatively low indicating that the amount of interference may be acceptable. In these instances, the power ratio may be less than the power ratio threshold thus prompting a switch from half duplex to full duplex operation. In various example embodiments, the determination of the significance of the interference may be based on factors in addition to or other than comparing the power ratio to a power ratio threshold, such as additional communication information or other types of information.

In some example embodiments, the duplex switching circuitry 128 may receive a duplex message comprising a command to switch to a particular duplex operation. The command may be based at least in part on a comparison of the power ratio and a power ratio threshold. According to certain embodiments, a duplex message may not be received if the current duplex operation is the desired duplex operation. After receiving the duplex message, the duplex switching circuitry 128 may switch the duplex mode to the mode commanded in the duplex message. The duplex switching circuitry 128 may further configure the terminal apparatus 102 for operation according to the commanded duplex operation.

According to various embodiments, a network entity may provide for transmission of the duplex message to the duplex switching circuitry 128. In certain embodiments, the network entity may send the duplex message after determining the power ratio, comparing the power ratio to the power ratio threshold, and/or determining whether to switch the duplex operation. In these instances, the network entity may be aware of the transmission power used in determining the power ratio by receiving the transmission power from the device switching circuitry 128 or commanding the terminal apparatus 102 to operate at a given transmission power. After sending the duplex message, the network entity may allocate network traffic according to the duplex operation commanded in the duplex message.

In various other embodiments, the duplex switching circuitry 128, the processor 120, or another component of the terminal apparatus 102 may perform at least one of determining the power ratio, comparing the power ratio to the power ratio threshold, and determining whether to switch the duplex operation, instead of the network entity. Additionally, the duplex switching circuitry 128 may, in certain embodiments, provide for transmission of a message to a network entity reporting that the current duplex operation should be switched. The duplex switching circuitry 128 may send this message in addition to or in place of the reporting message and/or status messages.

Figure 3 provides a signaling diagram according to an example

embodiment of the present invention in which the terminal apparatus determines the power ratio, compares the power ratio to the power ratio threshold, and determines whether to switch the duplex operation. According to the signaling diagram, a terminal apparatus may report its ability to support a duplex switching mode to a network entity. In response, the network entity may update a database to indicate the capability of the terminal apparatus to support the duplex switching mode. The network entity may provide the power ratio threshold to the terminal apparatus. The terminal apparatus may determine the power ratio based at least in part on communication information. The terminal apparatus may then compare the power ratio to the power ratio threshold provided by the network entity.

Subsequently, the terminal apparatus may determine the appropriate duplex operation based at least in part on the comparison. The terminal apparatus may then inform the network apparatus of the determined duplex operation. Optionally, the network entity may acknowledge receipt of the determined duplex operation. The terminal apparatus may then configure itself to operate in the determined duplex operation. Additionally, the network entity may allocate network traffic according to the determined duplex operation.

FIGs. 4A, 4B, and 4C illustrate an example embodiment of the present invention that supports a dynamically switching duplex mode. It will be understood that each element of the figures may be implemented by various means, and is not limited to the elements implemented in the example embodiment shown. According to some example embodiments, more or less, or even different, elements may be used to implement the example embodiment. Therefore, it is to be understood that the invention is not to be limited to the specific example embodiment disclosed in Figures 4A, 4B, and 4C, and that modifications and other embodiments are intended to be included within the scope of the invention.

In FIG. 4A, an example embodiment of a circuit for implementing a dynamically switching duplex mode is shown, which comprises an antenna 400, a receiver 460, a transmitter 462, amplifiers 440, 442, and switches 420, 422. According to FIG. 4A, both switches 420, 422 are in a closed position, thereby describing the state in which full duplex operation occurs. FIGs. 4B and 4C illustrate half duplex operation states. In particular, FIG. 4B shows switch 420 in a closed position and switch 422 in an open position. Accordingly, FIG. 4B demonstrates signal reception during half duplex operation. FIG. 4C, conversely, shows switch 420 in an open position and switch 422 in a closed position.

Accordingly, FIG. 4C demonstrates signal transmission during half duplex operation. According to some example embodiments, during full duplex operation both switches 420, 422 may remain closed. During half duplex operation, in various example embodiments, either switch 420 or switch 422 may be closed at any given time, but at no time may switches 420, 422 both be open or closed. In this regard, the operation of switches 420, 422 may be based on an exclusive or (XOR) operation in which only one switch may be closed at a given time.

The description provided above and generally herein illustrates example methods, example apparatuses, and example computer program products for providing for implementing a dynamically switching duplex mode. FIGs. 1 and 2 depict example apparatuses that may be configured to perform various

functionalities as described herein, including those described with respect to operations described with respect to the descriptions of FIGs. 3 and 4 A- 4C provided above, and with respect to the flowchart of FIG. 5, and the operations otherwise described herein.

The duplex switching circuitry 128 of example terminal apparatus 102 may be any means or device embodied, partially or wholly, in hardware, a computer program product, or a combination of hardware and a computer program product, such as processor 120 implementing stored instructions to configure the example terminal apparatus 102, memory 122 storing executable program code instructions configured to carry out the functions described herein, or a hardware configured processor 120 that is configured to carry out the functions of the duplex switching circuitry 128 as described herein. In an example embodiment, the processor 120 comprises, or controls, the duplex switching circuitry 128. The duplex switching circuitry 128 may be, partially or wholly, embodied as processors similar to, but separate from processor 120. In this regard, the duplex switching circuitry 128 may be in communication with the processor 120. In various example

embodiments, the duplex switching circuitry 128 may, partially or wholly, reside on differing apparatuses such that some or all of the functionality of the duplex switching circuitry 128 may be performed by a first apparatus, and the remainder of the functionality of the duplex switching circuitry 128 may be performed by one or more other apparatuses.

Further, the terminal apparatus 102 and the processor 120 may be configured to perform the following functionality via duplex switching circuitry 128. The duplex switching circuitry 128 may be configured to enable a terminal apparatus 102 to dynamically switch between full duplex and half duplex during operation. Further, performance of the functionality of the duplex switching circuitry 128 also describes various example method embodiments. The duplex switching circuitry 128 may be configured to cause or direct means, such as the processor 120 and/or the terminal apparatus 102 to perform various functionalities, such as those described with respect to FIGs. 3, 4A-4C, and 5, and as generally described herein.

For example, with reference to FIG. 5, the duplex switching circuitry 128 may be configured to optionally provide for transmission of a reporting message comprising an indication of the capability to support a dynamically switching duplex mode comprising both full duplex and half duplex operation. The duplex switching circuitry 128 may be further configured to provide for transmission of a status message comprising an indication of communication information at 500. The communication information may comprise an indication of a received signal strength. At 510, the duplex switching circuitry 128 may be configured to receive a duplex message comprising a command to switch to an indicated duplex operation. The command may be based at least in part on a comparison of a power ratio and a power ratio threshold. For example, the indicated duplex operation may be half duplex in the instance in which the power ratio is greater than the power ratio threshold and the current operation is full duplex, and the indicated duplex operation may be full duplex in the instance in which the power ratio is less than the power ratio threshold and the current operation is half duplex. The power ratio may be determined by calculating a ratio of a transmit signal strength to the received signal strength. Additionally, the duplex switching circuitry 128 may be further configured to switch to a duplex operation corresponding to the indicated duplex operation in the command. In some examples, a network entity may determine the power ratio and compare the power ratio to the power ratio threshold. Furthermore, in some embodiments, the network entity may allocate network traffic according to the indicated duplex operation in the command.

In some example embodiments, a separate status message may be provided for each of a plurality of channels or frequency bands. Further, in some example embodiments, a separate duplex message may be received for each of the plurality of channels or frequency bands. Additionally, a separate power ratio and a separate power ratio threshold may correspond to each of the plurality of channels or frequency bands. In this regard, each separate duplex message may comprise a separate command based at least in part on a comparison of the corresponding power ratio and the corresponding power ratio threshold for the respective channel or frequency band.

It will be understood that each block of the flowchart, and combinations of blocks in the flowchart, may be implemented by various means, such as hardware and/or a computer program product comprising one or more computer-readable mediums (as opposed to a computer-readable transmission medium which describes a propagating signal) having one or more computer program code instructions, program instructions, or executable computer-readable program code instructions stored therein. For example, one or more of the procedures described herein may be embodied by computer program instructions of a computer program product. In this regard, the computer program product(s) that embodies the procedures described herein may be stored by one or more memory devices (e.g., memory 122, volatile memory 40, or non-volatile memory 42) of a mobile terminal, server, or other computing device (e.g., the terminal apparatus 102) and executed by a processor (e.g., the processor 120 or processor 20) in the computing device. In some embodiments, the computer program instructions comprising the computer program product(s) that embodies the procedures described above may be stored by memory devices of a plurality of computing devices. As will be appreciated, any such computer program product may be loaded onto a computer or other programmable apparatus to produce a machine, such that the computer program product including the instructions which execute on the computer or other programmable apparatus creates means for implementing the functions specified in the flowchart block(s). Further, the computer program product may comprise one or more computer-readable memories on which the computer program instructions may be stored such that the one or more computer-readable memories can direct a computer or other programmable apparatus to function in a particular manner, such that the computer program product comprises an article of manufacture which implements the function specified in the flowchart block(s). The computer program instructions of one or more computer program products may also be loaded onto a computer or other programmable apparatus to cause a series of operations to be performed on the computer or other programmable apparatus to produce a computer-implemented process such that the instructions which execute on the computer or other programmable apparatus provide operations for implementing the functions specified in the flowchart block(s). Retrieval, loading, and execution of the program code instructions may be performed sequentially such that one instruction is retrieved, loaded, and executed at a time. In some example embodiments, retrieval, loading and/or execution may be performed in parallel such that multiple instructions are retrieved, loaded, and/or executed together.

Accordingly, execution of instructions associated with the operations of the flowchart by a processor, or storage of instructions associated with the blocks or operations of the flowchart in a computer-readable storage medium, support combinations of operations for performing the specified functions. It will also be understood that one or more operations of the flowchart, and combinations of blocks or operations in the flowchart, may be implemented by special purpose hardware-based computer systems and/or processors which perform the specified functions, or combinations of special purpose hardware and program code instructions.

The above described functions may be carried out in many ways. For example, any suitable means for carrying out each of the functions described above may be employed to carry out embodiments of the invention. In one embodiment, a suitably configured processor may provide all or a portion of the elements of the invention. In another embodiment, all or a portion of the elements of the invention may be configured by and operate under control of a computer program product. The computer program product for performing the methods of embodiments of the invention includes a computer-readable storage medium, such as the non-volatile storage medium, and computer-readable program code portions, such as a series of computer instructions, embodied in the computer-readable storage medium.

As such, then, some embodiments of the invention provide several advantages to computing devices and computing device users. Embodiments of the invention provide for implementing a dynamically switching duplex mode. In this regard, embodiments of the invention provide for dynamically operating in both full duplex and half duplex without the need for any duplexer filters. By operating in full duplex during typical operation when the magnitude of the transmit power in comparison to the received signal strength, for example, results in an acceptable level of interference, and operating in half duplex during stressful operation when the interference is unacceptable, the bulky, costly, and high power- consuming duplexer filters are not required to block the transmitter interference from the receiver. Various embodiments of the invention provide for the reduction of other filters and components in addition to the removal of the duplexer filters as a result of the dynamically switching duplex mode. For example, some

embodiments may result in the reduction of the number of switches, tunable filters, and the like. As a result, the amount of expensive, parallel signal processing may be reduced in certain embodiments. Embodiments of the invention advantageously allow for cheaper, smaller, mobile devices due to the removal and reduction of the above filters and components. That is, various embodiments of the inventions additionally result in the reduction of the complexity and cost of implementation of the hardware and software of mobile devices.

As a result of the reduction in space and cost provided by the removal and reduction of the duplexer and other filters, various embodiments allow for the implementation of more sophisticated network schemes in smaller mobile devices. For example, some small devices may gain the ability to implement sophisticated multiple-input and multiple-output (MIMO) schemes, such as 4x4, in a larger number of bands. Furthermore, the space saved by the removal and reduction of the duplexer and other filters may allow for including improved or additional solutions to overcome issues related to multi -radio RF interference, that is, interference from other neighboring mobile devices or radios. Embodiments of the invention may also provide for the ability to operate at a multiplicity of frequency bands using fully generic, highly programmable, software designed or mixed software and minimal hardware designed networking solutions. As a result, the number of platform variants that must be supported by a given standard or mobile device may be reduced due to the ability to support more generic solutions.

Various embodiments of the invention may further result in the ability to predefine classes supporting the dynamically switching duplex mode, which classes may be known by the network in advance. In these instances, the amount of signaling between the mobile device and network may be reduced.
