Abstract

Disclosed herein is an approach for improving energy efficiency of a wireless communication device by reducing power distributed to receiver chain circuits (RCCs) based on determining whether the incoming wireless data is to be received and processed by the RCCs within an upcoming time duration. A device can identify a plurality of RCCs for processing data to be received by the device from a network. The device can determine that a first RCC of the plurality of RCCs is to receive the data within a time duration and that a second RCC of the plurality of RCCs is to receive no data within the time duration. The device can cause, responsive to the determination, power to be reduced to the second RCC and not be reduced to the first RCC, within the time duration.

CPC 440 may remain available (eg, not degrade) during the time duration 435 to those RCCs 415 (or circuit components 420 thereof) that are expected to receive the incoming data 410 during the time duration 435 power.

The status of an application (e.g., whether in the foreground or background) can be exploited to determine whether certain data will be received, and thus one or more RCCs can be activated to receive during the time that the data is expected Said data for said application. For example, if the application is inactive, or in the background, receiving data for the application may not be important/necessary. As such, the corresponding RCC need not be activated to receive such data. Conversely, if the application is active, or in the foreground, it may be important to receive data for the application.

RCC 415 may include any organized, configured, constructed or designed circuit components 420 that may be configured into a link or in a specific configuration or sequence to process data 410 in a specific manner. For example, a receiver chain circuit 415 may include a link of circuit components 420 that may be interconnected to each other, each circuit component 420 being a part of addressing the data processing.

For example, an RCC 415 may include an antenna that may be connected to a low-pass, band-pass, or high-pass filter, the output of which may be connected to a low-noise amplifier, and the output of the amplifier may be connected to another A signal filter, the output of which can be connected to a signal mixer receiving an oscillator signal.

Circuit components 420 may be designed to be contained within an individual RCC 415 or may be shared across multiple RCCs 415. For example, one RCC 415 may share an antenna, which may be shared with one or more other RCCs 415. In such an example, the shared component may not be powered off if other RCCs 415 sharing the antenna will also be using the antenna during that time.

RDM 425 may determine which RCCs 415 will receive and process data 410 that is expected to arrive during a specific upcoming time 435 of the time interval. RDM 425 may determine the likelihood or probability that data will be received within an upcoming time duration 435 of an upcoming time interval 430 (eg, an upcoming data frame). For example, if data is received within time intervals 430 corresponding to 15 frames per second, each time interval 430 may correspond to 1/15 of a second. The duration 435 within each time interval 430 may correspond to or be associated with the intermittent received DRX cycle (eg, active/on, or sleep/off cycle).

5 is an example of a graph 500 depicting a power level 510 provided to a plurality (eg, all) of RCCs 415 of a UE 450 as a function of time. Diagram 500 illustrates a time interval 430 plotted on a timeline 505 and encompassing or coinciding with a DRX cycle of the RCC 415 that includes a DRX conduction period 515 (eg, active phase) and a DRX Off period 520 (eg, sleep phase). Diagram 500 illustrates that time interval 430 includes durations 435a, 435b, and 435c as they correspond to the DRX on or off periods. The power level 510 of the RCC 415 over a time interval 430 may vary during different portions of the time interval 430 because according to the data 410 such duration 435 will be determined by the power level in the RCC 415 In anticipation of some receiving and others not, the power provided to (eg, consumed by) the RCCs 415 may be reduced to some of the RCCs 415 . The time intervals 430 may correspond to a configuration of frames, which may include, for example, 15 frames per second, where one time interval 430 may correspond to 66.66 ms.

A first portion of the time interval 430 may correspond to a DRX on period 515 during which all RCCs 415 of the UE 450 may be active and fully powered. The power level 510 may be high during the DRX conduction period 515, which may also include, correspond to, or coincide with the time period 435a. The system 400 may determine (e.g., predict) that the data 410 is likely to be received for one or more RCCs 415 during the time duration 435a, and thus the power level 510 to the RCCs 415 may remain high. of. Likewise, the system 400 may determine (eg, predict) that there is a high probability that the data 410 is received during the time duration 435b even if the time duration 435b corresponds to or coincides with a DRX off period 520 (e.g. sleep stages). However, time duration 435b may correspond to a time duration 435 adjacent/close to the DRX on period 515, and thus there may still be a high probability that data 410 will be received during said time period 435b. In some embodiments, the power level 510 may be fully aligned with the DRX on-period 515 and the DRX off-period 520 (e.g., the lines of the power level 510 may be aligned with the on- and off-periods 515 and 520) . In some embodiments, the power level 510 may remain high, such as during an active portion within a portion of the DRX off period 520 adjacent the DRX on period 515 . This can be accomplished because network jitter and latency may create the possibility that some data may arrive outside of the DRX on period 515. Time duration 435c may correspond to the portion of time interval 430 during a DRX off period 520 (eg, sleep) during which the system 400 may determine that data will not be received. The power level 510 during the time duration 435c may be lower than during the time durations 435a and 435b. The DRX cycle may be periodic and may conform to the time interval 430, and the power level of the RCC 415 may include a portion of the high power level 510, which includes the DRX conduction period 515 and its corresponding adjacent duration. 435 (eg, surrounding the conduction period 515 ), and the portion of the low power level 510 that is within the off period 520 and not adjacent to the conduction period 515 .

The DRX cycle or on/off period (of one or more of the RCCs) may or may not be mapped to the connected mode DRX (C-DRX) cycle or on/off period. During outages, it may be configured via the network 460 (eg, a 4G or 5G cellular communication device communicates with the UE 450 via the network 460). In some embodiments, certain on or off periods of a C-DRX may map one-to-one to the DRX cycle of the UE 450 (eg, DRX on period 515 or DRX off period 520). At times, the on or off period of the C-DRX may be offset from the on or off period of the DRX cycle of the UE 450 (eg, 515 or 520). The offset between the DRX and C-DRX periods (eg, on- and off-periods) may be such that the on-periods 515 and/or off-periods 520 of the DRX and C-DRX completely overlap, Partially overlapping and partly non-overlapping, or they may not overlap at all (eg, they are inverse phase with respect to each other).

The DRX periods (eg, DRX on/off periods) of one or more of the RCCs may be determined based on flow characteristics. For example, DRX function 445 may establish the DRX cycle (e.g., conduction of the DRX cycle) based on traffic characteristics of an application 405 operating on the UE 450 (corresponding to one or more of the RCCs). and shutdown period). The application 405 may be an application operating in the foreground of the UE 450 or an application assigned high priority relative to other applications 405 .

The DRX function 445 may determine DRX on/off (of one or more of the RCCs) based on the C-DRX configuration from the network 460 or without any C-DRX configuration from the network. period. For example, the DRX function 445 may determine the on period 515 or the off period 520 of the DRX cycle based on a C-DRX signal/configuration from a device (eg, device 455) on the network 460. For example, the DRX function 445 may determine the on-period 515 or off-period 520 of the DRX cycle without (or independently of) any C-DRX signal/configuration. For example, the DRX function 445 may determine the on/off period of DRX on the UE 450 based on the timing of the incoming network traffic related duration 435 and/or time interval 430 .

In one example, the present disclosure relates to a UE 450, which is a wireless communication device (eg, a head-up display, a smartphone, or a tablet). The UE 450 may include one or more processors (eg, processing unit 316) that may be configured (eg, have or execute instructions) to identify any number of RCCs 415 for processing by the wireless communication device Data 410 received from a wireless network 460 (eg, UE 450). Data 410 may include data for an application 405 executing on a UE 450. The one or more processors (eg, processing unit 316) may be configured to determine (eg, predict or estimate) the likelihood (eg, exceed a threshold level) of a particular application and/or the plurality of A first RCC 415 of RCCs 415 receives the data 410 within a time duration 435 while another application and/or a second RCC 415 of the plurality of RCCs 415 receives the data 410 during the time duration 435 No data received within 410. The time duration 435 may include a portion of a time interval 430 (eg, a frame of transmitted data). The one or more processors (eg, processing unit 316) may be configured to cause power to the second RCC 415 to be reduced during the first time duration 435 in response to the determination, and Power to the first RCC 415 is not reduced. For example, the RDM 425 may identify RCCs 415 that are used to process material 410 that is judged or predicted to be received during the time duration 435, and may identify RCCs 415 that are not used to process any incoming material 410, And the power of those RCCs 415 (or their corresponding circuit components 420) that are not processing data 410 during that time duration 435 can then be reduced.

The time duration 435 may be within an off period (eg, sleep phase) of a discontinuous reception (DRX) cycle of the plurality of RCCs 415 of the wireless communication device, or corresponding thereto (eg, aligned in time). The one or more processors (eg, processing unit 315) may be configured such that during an on-time period (eg, active phase) of a discontinuous reception (DRX) cycle, to the first The power of the RCC 415 and the second RCC 415 is not reduced. The one or more processors may be configured to determine the other of the first RCC 415 and the second RCC 415 during an off period (eg, sleep phase) of a discontinuous reception (DRX) cycle. Within the time duration 435 (eg, 435b) there is a possibility of receiving the data 410 (eg, at least exceeding a defined threshold). The one or more processors may be configured to respond to the first RCC 415 and the second RCC 415 each having a possibility of receiving the data 410 within the further time duration 435b. (eg, at least exceeds a defined threshold value) such that the power to the first RCC 415 and the second RCC 415 is not reduced within the another time duration 435b. The RCC 415 may then be fully powered and operational during at least a portion of the DRX cycle during the off period.

The one or more processors may be configured to determine that the first RCC 415 and the second RCC 415 each have at least a defined possibility (eg, at least a probability of exceeding a critical level). The data 410 is received within the time duration 435, and the second RCC 415 does not receive data within the time duration. This determination may be made by determining that a first application 405 or function associated with the first RCC 415 is expected to receive the data 410 within the time duration 435 associated with the second RCC 415 A second application 405 or function that is not expected to receive data 410 within the time duration 435 is made. The first application 405 may be an active application 405 or operate in the foreground, and the second application 405 may be an inactive application or operate in the background. The first or second function may belong to the same or different applications 405.

Each of the plurality of RCCs 415 may include any number of component circuits 420, such as at least one or more of the following: multiplexers, filters, mixers, amplifiers, or analog-to-digital converters. RCC 415 may share some of the components, such as antennas or oscillators. When an RCC 415 has its power managed (eg, turned off or reduced), the CPC 440 may manage the power of component circuits 420 that are not shared with the RCC 415 when one or more of the RCCs 415 are turned off or turned off. The 435 will be operational during the same period of time when power is reduced.

The one or more processors may be configured to cause at least one of the components 420 of the second RCC 415 (eg, a multiplexer, filter, mixer, amplifier, or analog-to-digital converter) One is disconnected or gated from the power source so that power to the second RCC 415 is reduced. Additionally or alternatively, one or more circuit components 420 may have their power (eg, voltage and/or current) reduced but not completely turned off.

The one or more processors may be configured to determine that a third RCC 415 of the plurality of RCCs 415 has not received data within the time duration. In response to the determination that the third RCC 415 did not receive data 410 within the time duration 435, the one or more processors may be configured to cause within the first time duration to The power of the third RCC 415 is reduced. The first time duration may be within (or correspond to, or be temporally aligned with) an off-period of a discontinuous reception (DRX) cycle.

The one or more processors may be configured to determine that an application 405 associated with the first RCC 415 received a previous request within a portion of a previous time interval 430 corresponding to the time duration 435 Information 410. The one or more processors may predict that the first RCC 415 will receive the data within the time duration 435 in response to the application 405 receiving the previous data within the portion. 410. Certain RCCs 415 may be related to or correspond to specific types of data 410, such as streaming data, video or audio data. Such RCC 415 may be assigned to the data 410 being received in response to characteristics of the data 410 identified by the RDM 425 identifying the type of data 410 being received.

The one or more processors are configured to determine that an application 405 associated with the second RCC 415 did not receive a previous message within a portion of a previous time interval 430 corresponding to the time duration 435 . Information 410. The one or more processors may be configured to predict in response to the application not receiving the previous data 410 within a portion of the previous time interval 430 (e.g., time duration 435). (e.g., judging or estimating) that the second RCC 415 did not receive data 410 during the time duration 435 (or in some cases, it did not need to receive data, such as for a background application) .

In certain features, the solution relates to a non-transitory computer-readable medium storing program instructions. The instructions may cause at least one processor of a UE 450 to identify a plurality of RCCs 415 for processing data to be received from a wireless network via the wireless communication device. The one or more processors may determine that a first RCC 415 of the plurality of RCCs 415 received the data 410 within a time duration 435 and a second RCC of the plurality of RCCs 415 415 No data 410 was received within the time duration 435.

6 is an example flow diagram depicting a method 600 of managing power to a receiver chain circuit based on determining (e.g., predicting) whether data is expected to be received (and/or e.g., during a particular upcoming time). needs to be received for an application). Method 600 may include actions 605-625. The method 600 may be performed, for example, by one or more features of the system 400, including features or examples depicted or discussed with respect to FIGS. 1-4. At act 605, the method identifies a receiver chain circuit (RCC). At act 610, the method determines RCCs that are receiving data, and those that are not. At act 615, the method reduces power to RCCs that are not receiving data and maintains power to RCCs that are receiving the data.

At act 605, the method identifies a receiver chain circuit (RCC). The user equipment (eg, a wireless communication device) may identify a plurality of RCCs for processing data to be received from a wireless network by the wireless communication device. For example, the UE may identify a set of RCCs for receiving wireless data. Certain of the RCCs may be associated or configured to handle a specific type of data (e.g., video data, streaming data, AR/ VR data, or control data).

Each of the plurality of RCCs may include any number of circuit components. The circuit components of each of the RCCs may be arranged, configured, or organized to process a specific type of data in a specific manner. For example, some RCCs can be configured to handle video data, some RCCs can be configured to handle streaming data, some RCCs can be configured to handle AR/VR data, and other RCCs can be configured to handle background application data. (For example, command, control or feedback messages).

The wireless communications device may identify the circuit components in each of the RCCs. Circuit components may include one or more of any of the following: multiplexers, signal filters (e.g., high-pass, low-pass, band-pass, or anti-aliasing filters), mixers (used to mix two or more signals ), an amplifier (eg, a low-noise amplifier or a power amplifier), or an analog-to-digital converter or a digital-to-analog converter. The wireless communication device may include a processor or controller for processing data.

At act 610, the method determines that a first RCC will receive the data. The UE (eg, the wireless communication device) may determine that a first RCC of the plurality of RCCs will receive the data within a time duration (eg, for a specific application). The UE may determine that a second RCC of the plurality of RCCs has not received data within the same time duration (eg, for a certain application). The UE may identify or determine that all of the RCCs are expected to receive incoming radio data during an upcoming time duration, and that all of the RCCs are expected to receive no incoming radio data during the same upcoming time duration. wireless data. The UE may do this based on observations of previous time intervals where data has been received within one or more durations of the time interval but not received within other durations of the time interval. this judgment. The UE may make this determination in relation to all incoming wireless data, or based on (or based on) data from a specific application. For example, a receiving data manager may determine that a particular application will receive a particular data in a previous time interval based on the observation that during the same time duration in the upcoming time interval. The same application will receive said data within a specific upcoming time duration.

In some embodiments, the time duration is within an off period of a discontinuous reception (DRX) cycle of receiver chain circuits of the wireless communication device. The UE (eg, the wireless communication device) may determine that the first RCC and the second RCC respectively have another time duration of an off period of a discontinuous reception (DRX) period. There is a defined probability (eg, a likelihood/probability of exceeding a defined threshold) within which the data (eg, data for a particular application) is received. The wireless communication device may determine that the first receiver chain circuit and the second receiver chain circuit each have at least a defined possibility of receiving the data within the time duration, and should, for example, is active to receive such data (e.g., for a first application associated with a certain priority/status, or for a first function of the first application). This determination may be made by determining that a first application or function associated with the first RCC is expected to receive the data within the time duration, and a second application associated with the second RCC The program or function is expected to be built without receiving data within the stated time duration. The first and second functions may be functions of the same application. For example, the two functions may correspond to two different types of data with the same function and may be processed by two different RCCs.

The wireless communication device may determine that a third receiver chain circuit of the plurality of receiver chain circuits has not received data within the time duration (e.g., no data is expected to arrive, or the data not necessarily received/processed). The wireless communication device may determine that an application associated with the first receiver chain circuit received previous data within a portion of a previous time interval corresponding to the time duration. The wireless communications device may predict that the first receiver chain circuit will receive the data within the time instance in response to the application receiving the previous data within the portion.

For example, the applications may include applications that operate in the foreground or have high priority, while other applications may operate in the background or have low priority. The wireless communication device may determine the RCC during an upcoming time duration of an upcoming time interval (eg, frame) in response to the application being identified as a high priority (or foreground) application. to receive said information.

The wireless communication device may determine that an application associated with the second receiver chain circuit did not receive previous data within a portion of a previous time interval corresponding to the time duration. The wireless communication device may predict that the second receiver chain circuit did not receive data for the duration of time in response to the application not receiving the previous data during the portion.

At act 615, the method reduces power to the RCCs that are not receiving the data and may maintain/supply (normal active state) power to the RCCs that are receiving the data. The wireless communication device may, in response to the determination in act 610, cause the power to the second RCC (which is not expected to process data) to be reduced during the first time duration, and to the first RCC The power (expected to process data) is not reduced. The wireless communication device can prevent power to the first receiver chain circuit and the second receiver chain circuit from being reduced during a conduction period of a discontinuous reception (DRX) cycle. In response to the determination that the first RCC and the second RCC each have a probability (exceeding a defined threshold) of receiving the data within the other time duration, the wireless The communication device may cause power to the first RCC and the second RCC not to be reduced during the further time duration.

The wireless communications device may utilize a circuit power controller to reduce or disconnect power to the one or more circuit components of the RCC. For example, a processor may execute or transmit a command to cause power to be reduced to disconnect one or more circuit components of the RCC that are determined or predicted not to receive data during the upcoming time duration. For example, a circuit power controller may utilize gates or logic structures to reduce, disable, or stop power being provided to all RCCs that are predicted not to process data for the duration of the time. Power to the RCC or circuit components of the RCC may be reduced or disconnected throughout or part of the time duration.

The wireless communications device may cause power to the second RCC to be reduced by disconnecting or gating at least one component circuit of the second RCC from the power source. For example, the wireless communication device may disconnect or gate power (or reduce power) to any one or more of the following: the multiplexer, filter, mixer, amplifier, or analog of the second RCC to digital converter. For example, the wireless communications device may cause power to be reduced or disconnected to one or more circuit components of an RCC that are not shared with other RCCs being used. The wireless communication device may maintain power to common circuit components with the RCC to be used during the duration of time in which data is expected to be received.

The wireless communication device may respond to the determination that the third RCC does not receive data within the time duration, so that the power to the third RCC within the first time duration is be lowered. The first time duration may be within an off period of a discontinuous reception (DRX) cycle, or within an on period of the DRX cycle. The first time duration may be within an off period of the on period of the DRX period adjacent to the DRX period.
