DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS

[0014] The following clearly and completely describes the technical solutions in the embodiments of the present application in conjunction with the drawings in the embodiments of the present application, and obviously, the described embodiments are only some of the embodiments of the present application, and not all of the embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of the present application belong to the protection scope of the present application.

[0015] The terms "first," "second," etc. in the specification and claims of the present application are intended to distinguish between similar objects and are not intended to describe a particular order or sequence. It is to be understood that data so used are interchangeable where appropriate, such that the embodiments of the present application may be performed in an order other than that shown or described herein, and that the objects distinguished by "first" and "second" are generally of the same type and do not limit the number of objects, e.g., the first object may be one or more. Note that "and / or" in the specification and claims represents at least one of the objects connected, and the character " / " generally represents an "or" relationship between the related objects.

[0016] It should be noted that the techniques described in the embodiments of the present application are not limited to Long Term Evolution (LTE) / LTE-Advanced (LTE-A) systems, but can also be applied to other wireless communication systems, such as Code Division Multiple Access (CDMA), Time Division Multiple Access (TDMA), Frequency Division Multiple Access (FDMA), Orthogonal Frequency Division Multiple Access (OFDMA), Single-carrier Frequency-Division Multiple Access (SC-FDMA), and other systems. The terms "system" and "network" in the embodiments of the present application are always used interchangeably, and the techniques described may be used in the above-mentioned systems and radio technologies, or in other systems and radio technologies. However, although the following description describes a New Radio (NR) system for illustrative purposes and uses NR terminology in most of the following description, these techniques may be applied to applications other than NR system applications, such as 6th Generation (6G) communication systems.

[0017] FIG. 1 shows a block diagram of a wireless communication system to which the embodiment of the present application can be applied. The wireless communication system includes a first device 11 and a second device 12. Here, the first device may be a reader device, and the second device may be a backscatter device, and the reader device may be a terminal or a network device, and the terminal may be called a terminal device or a user terminal (User Equipment, UE), and the terminal may be a terminal side device such as a mobile phone, a tablet personal computer, a laptop computer (or called a notebook computer), a personal digital assistant (PDA), a palmtop computer, a netbook, an ultra-mobile personal computer (UMPC), a mobile Internet device (Mobile Internet Device, MID), a wearable device, a vehicle user equipment (VUE), a pedestrian user equipment (PUE), and the wearable device includes a bracelet, an earphone, glasses, and the like. It should be noted that the embodiments of the present application are not limited to a specific type of terminal.The network equipment may be a base station or a core network, where the base station may be called a Node B, an evolved Node B, an access point, a base transceiver station (BTS), a radio base station, a radio transceiver, a basic service set (BSS), an extended service set (ESS), a B node, an evolved B node (eNB), a home B node, a home evolved B node, a WLAN access point, a WiFi node, a transmitting receiving point (TRP), or any other suitable term in the art, and as long as the same technical effect is achieved, the base station is not limited to a specific technical term, and it should be explained that in the embodiments of this application, only a base station in an NR system is taken as an example, but the specific type of the base station is not limited.

[0018] For ease of understanding, the following describes some contents regarding the embodiments of the present application.

[0019] This is Connected Discontinuous Reception (CDRX) for LTE and New Radio (NR).

[0020] Both LTE and NR have a DRX mechanism, and UE power saving is achieved by configuring DRX on and off times. The on duration period is the period during which DRX is on, and if there is no scheduling, the UE enters an off period of one DRX cycle after the on duration period. When configuring DRX, parameters such as onDurationTimer, drx-InactivityTimer, drx-RetransmissionTimer, and longDRX-CycleStartOffset are generally configured.

[0021] After configuring DRX in the UE, if the transmission or reception data decoding fails, the UE needs to enter the activation time to monitor the control channel and wait for retransmission by network scheduling.

[0022] During the On Duration period, if a UE is scheduled in a slot to receive data, it is likely to continue to be scheduled in the next few slots. Therefore, every time a UE is scheduled to transmit data for the first time, a timer drx-InactivityTimer is started or restarted, and the UE is placed in the active state until the timer times out.

[0023] For downlink data reception, the UE receives downlink data transmission indicated by a physical downlink control channel (PDCCH) and feeds back hybrid automatic repeat request (HARQ) information, and then starts a downlink backhaul timer (HARQ RTT (Round Trip Time) Timer) for the corresponding HARQ process. After the HARQ RTT Timer times out and the data decoding of this HARQ process is not successful, the UE starts a retransmission timer (drx-RetransmissionTimer) to monitor the PDCCH and wait for transmission.

[0024] For uplink data transmission, after the UE receives the uplink data transmission indicated by the PDCCH, it starts the uplink backhaul timer HARQ RTT Timer for the corresponding HARQ process. When the HARQ RTT Timer times out, the UE starts the retransmission timer (drx-RetransmissionTimerUL) and enters the active state to monitor the PDCCH and wait for the network-scheduled transmission.

[0025] The following describes in detail the discontinuous transmission method according to the embodiments of the present application through specific embodiments and its application scenarios in conjunction with the drawings.

[0026] Referring to FIG. 2, FIG. 2 is a flow chart of a discontinuous transmission method according to an embodiment of the present application, which is used in a first device, as shown in FIG. 2 : The method includes step 201 in which a first device transmits a first signal for a second device to collect energy based on a target Discontinuous Transmission (DTX) arrangement.

[0027] The first device may be understood as a reader device, and provides energy to the second device by transmitting a first signal, and optionally, the first device may further read a second signal transmitted by the second device. For example, in one embodiment, the first device may be a mobile phone, a dedicated device, or a base station, and the dedicated device may be understood as a dedicated device used only for energy collection of the second device, such as a mobile battery that can transmit a signal. The second device may be understood as a backscatter device or a tag device, and can collect the signal energy provided by the first device, and optionally, the second device can also transmit a second signal using the collected energy. For example, the second device may be a device such as smart glasses, and the first device is a mobile phone, and the smart glasses transmit a second signal to the mobile phone by collecting the energy of the signal transmitted by the mobile phone.

[0028] Or, the first device is a base station or a signal source, and the second device is an associated device such as a Large Intelligent Surface (LIS) or an Intelligent Reflecting Surface (IRS) associated with the base station or the signal source. The base station or the signal source provides energy to the LIS or the IRS by transmitting a first signal, and the device such as the LIS or the IRS transmits a second signal based on the collected energy of the base station or the signal source.

[0029] It should be understood that the signal transmitted between the first device and the second device may be a radio frequency signal or an electromagnetic signal or an optical signal or any other signal capable of providing energy.

[0030] In an embodiment of the present application, a first device discontinuously transmits the first signal based on a target DTX configuration, and a second device acquires the first signal energy transmitted by the first device based on the target DTX configuration, and completes the transmission of its own signal based on the acquired energy.

[0031] In an embodiment of the present application, the first device transmits a first signal for the second device to collect energy based on the target DTX configuration. In this way, the first device can transmit the first signal non-continuously, thereby reducing the power consumption of the first device.

[0032] In one embodiment, the target DTX configuration comprises: Long DTX cycle and DTX long period and time offset, DTX duration (DTX_onDurationTimer) and DTX inactivity timer (DTX_inactivitytimer), DTX short cycle (short DTX cycle) and a DTX short timer; Here, the DTX long cycle is M times the DTX short cycle, and M is an integer greater than 1.

[0033] In the embodiment of the present application, the target DTX configuration may be a DTX configuration agreed upon by a protocol, or may be a DTX configuration instructed by a network device or a second device, and is not further limited herein.

[0034] Optionally, in one embodiment, the long DTX cycle or the short DTX cycle includes a DTX duration and a DTX off time, and the step of the first device transmitting a first signal based on a target discontinuous transmission DTX configuration includes: a first device transmitting a first signal within the DTX duration; If the first device does not transmit a first signal during the DTX off time or the first device does not receive a second signal transmitted by the second device during the DTX duration time, the first device enters the DTX off time after the DTX duration time, and the first device does not transmit a first signal during the DTX off time.

[0035] As shown in FIG. 3, in general, one DTX period includes a DTX duration and a DTX off time.

[0036] The DTX duration may be understood as the duration of a DTX cycle and may be referred to as a DTX on interval, and the DTX off time may be understood as the off time of a DTX cycle and may be referred to as a DTX off interval.

[0037] In the embodiment of the present application, one DTX cycle includes two parts: DTX duration and DTX off time. During the DTX duration, a first device can transmit a first signal, and a second device can utilize the energy of this first signal, and if the first device does not receive a second signal from the second device during this DTX duration, the first device will enter a DTX off time after the DTX duration period, and during this DTX off time, the first device will not transmit a first signal.

[0038] It should be understood that the first device receiving the second signal may be understood as the first device demodulating the information carried by the second signal transmitted by the second device, or the energy of the received second signal transmitted by the second device being higher than a preset threshold. Correspondingly, if the above conditions are not met, it may be understood as the first device not receiving the second signal transmitted by the second device.

[0039] Optionally, before the step of the first device transmitting a first signal based on a target discontinuous transmission DTX arrangement, the method further comprises: The method further includes receiving, by the first device, first instruction information transmitted by the second device or a network device; Here, the first instruction information is used to indicate the target DTX configuration, or the first instruction information is used to indicate that one set of DTX configurations among at least two sets of DTX configurations is the target DTX configuration.

[0040] In the embodiment of the present application, the first instruction information is used to indicate the target DTX configuration, which may be understood as the first instruction information indicating the value of each parameter in the target DTX configuration, and the second device or the network device can flexibly indicate the value of each parameter in the target DTX configuration, thereby improving the flexibility of control over the target DTX configuration. The first instruction information is used to indicate that one set of DTX configurations among at least two sets of DTX configurations is the target DTX configuration, which may be understood as the first instruction information indicating identifier information of a certain set of DTX configurations, for example, the at least two sets of DTX configurations and the numbers of the DTX configurations of each set may be configured in advance or agreed upon by a protocol, and the first instruction information indicates the numbers of the certain set of DTX configurations, and the first device can determine the target DTX configuration based on the numbers indicated by the first instruction information, and since the DTX configuration is indicated by the number, the overhead of the first instruction information can be reduced and resources can be saved.

[0041] It should be understood that in the embodiment of the present application, each set of DTX configurations may be understood as one transmission mode, where the values ​​of one or more DTX configuration parameters may be different between different transmission modes. The at least two sets of DTX configurations may be transmitted by the network device or the second device, and are not further limited herein.

[0042] Optionally, in one embodiment, the step of transmitting a first signal by the first device based on a target discontinuous transmission DTX configuration when the target DTX configuration includes the DTX deactivation time value comprises: when the first device receives a second signal transmitted by the second device, the first device starts the DTX deactivation timer; transmitting the first signal with a first DTX period if the DTX deactivation timer has not timed out; and transmitting the first signal in a second DTX period if the DTX deactivation timer times out.

[0043] In the embodiment of the present application, the DTX inactivation timer may be called DTX_inactivity timer and may correspond to the DRX_inactivity timer of CDRX. For example, this DTX inactivation timer may be timed in a countdown manner. For example, if the DTX inactivation timer has already started, and the first device has not received the second signal transmitted by the second device in a certain slot, the DTX inactivation timer is decremented, i.e., subtract 1 from the timer.

[0044] As shown in Figure 4, since the first device receives the second signal transmitted by the second device at time T1, the first device starts the DTX deactivation timer in the following slot, and since the first device never receives the second signal transmitted by the second device from time T1 to time T2, the DTX deactivation timer times out at time T2. After the DTX deactivation timer times out, the first device does not transmit the first signal because it is in the OFF period of the DTX period at this time.

[0045] The magnitude of the time length of the first DTX period and the second DTX period may be set according to actual needs, for example, in one embodiment, the first DTX period is smaller than the second DTX period, i.e., the magnitude of the time length of the first DTX period is smaller than the magnitude of the time length of the second DTX period. Since the first DTX period is set smaller than the second DTX period, it represents that the second device may continue to transmit the second signal within a certain time after triggering the start of the DTX deactivation timer when the DTX deactivation timer has not timed out, and at this time, the first signal is transmitted in the first DTX period, thereby shortening the period of transmitting the first signal, which is favorable for the second device to collect the energy of the first signal more quickly, thereby reducing the delay of the second device transmitting the second signal. When the DTX deactivation timer times out, it represents that the transmission of the second signal may have already been completed, and at this time, the first signal is transmitted in the second DTX period, thereby further reducing the power consumption of the first device.

[0046] Furthermore, after the first device starts the DTX deactivation timer when the first device receives a second signal transmitted by a second device, the method further comprises: The method further includes, if the first device re-receives a second signal transmitted by the second device before the DTX deactivation timer times out, the first device restarting the DTX deactivation timer.

[0047] In this embodiment, the first device can ensure that the delay in the second device transmitting the second signal is reduced when the second device transmits the second signal multiple times within a certain period of time by restarting the DTX deactivation timer every time the first device receives a second signal before the DTX deactivation timer expires.

[0048] Exemplarily, the reader device operates in a first preset transmission mode (e.g., period 1), and when the reader device receives a second signal transmitted by the tag device, it starts a timer (DTX_inactivity timer) to count down, and before this timer expires, the reader device transmits the first signal in the second preset transmission mode, and when this timer expires, the reader device switches to another preset transmission mode or the first preset transmission mode.

[0049] Here, if the reader device receives a signal transmitted from the tag again before this timer expires, the timer will be restarted, and the second preset transmission mode may be understood as a transmission mode corresponding to a period smaller than period 1, or a transmission mode in which the tag continuously transmits a signal to collect energy.

[0050] Optionally, the step of the first device transmitting a first signal based on a target discontinuous transmission DTX arrangement includes: When a DTX deactivation timer of a DTX long period of the first device is started and times out, the first device transmits the first signal with the DTX short period; transmitting the first signal in the DTX long cycle if the DTX deactivation timers of the N DTX short cycles have not been started within N consecutive DTX short cycles (N is a positive integer).

[0051] Illustratively, in this embodiment, for example, as shown below, the first device supports a short DTX function, and the first device operates after the DTX_inactivity timer is activated during a long DTX cycle, in which case the first complete DTX cycle after the expiration of the DTX_inactivity timer is a short DTX cycle, and if the DTX_inactivity timer has never been on during N (DTX short cycle timer) consecutive short DTX cycle periods (as shown in FIG. 5, N=3), the first device enters a long DTX cycle after N short DTX cycles.

[0052] In another embodiment, the target DTX configuration comprises: DTX period, The time position at which the first signal should be transmitted within a DTX period and the value of the parameter are included.

[0053] For example, a DTX period is 10 slots, or 10 ms. The time positions at which the first signal needs to be transmitted within this DTX period are the first slot and the third slot.

[0054] In one embodiment, when the DTX configuration is set based on the search space, the network device or the second device may set multiple DTX configurations for the terminal, and switch between the DTX configurations according to a certain rule. Each DTX configuration may be understood as a set of DTX configurations or a transmission mode, where the values ​​of one or more DTX configuration parameters may be different between different transmission modes.

[0055] Optionally, before the step of the first device transmitting a first signal based on a target discontinuous transmission DTX arrangement, the method further comprises: The first device determines the target DTX arrangement based on the received second instruction information sent by the second device or a network device; The first device determines a first preset DTX configuration as the target DTX configuration when receiving a second signal transmitted by the second device; and when the first device does not receive a second signal transmitted by the second device within a preset time period, the first device determines a second preset DTX configuration as the target DTX configuration.

[0056] In an embodiment of the present application, the second instruction information may be transmitted by dedicated signaling. The first preset DTX configuration may be understood as a pre-agreed DTX configuration, or as a DTX configuration corresponding to a second signal, and may determine a target DTX configuration based on a feature or pattern of the second signal, for example. Determining the first preset DTX configuration as the target DTX configuration may be understood as activating the first preset DTX configuration.

[0057] Optionally, in one embodiment, when a second signal transmitted by the second device is received, the first pre-set DTX arrangement is determined as the target DTX arrangement at a target time that is N time units after receiving the second signal.

[0058] In this embodiment, the time unit may be slot or symbol or millisecond, and the value of N may be agreed upon by a protocol or configured by a network device, and is not further limited here.

[0059] Exemplarily, the method for switching between DTX patterns is as follows.

[0060] First, the DTX pattern is indicated by dedicated signaling, for example, the tag device or the base station directly instructs the reader device to use the target DTX pattern.

[0061] Optionally, values ​​for each parameter of the target DTX pattern may be indicated.

[0062] Optionally, it may further instruct the reader device on the radiation power value or instruct the reader device to increase or decrease the step size of the radiation power.

[0063] Alternatively, multiple sets of DTX patterns may be pre-arranged or pre-contracted, and one of the sets of DTX patterns may be indicated.

[0064] Optionally, the Reader device transmits a signal in a DTX pattern as instructed by the signaling.

[0065] Second, activate one DTX pattern by receiving a target signal / signaling.

[0066] For example, the reader device receives a certain target signal / signaling from the tag (e.g., receives a target signal from the tag device at the same carrier frequency as the reader device's first signal and determines that the tag device is transmitting a target signal, e.g., by energy detection (a value that reaches a certain pre-set threshold)), thereby activating / switching to a certain DTX pattern.

[0067] Optionally, the DTX pattern is pre-arranged or the DTX pattern is determined based on the signal characteristics / pattern of the detected tag.

[0068] Here, the activation time is the Nth symbol or slot or milliseconds after the Reader device receives the target signal / signaling. Alternatively, the value of N may be negotiated by the protocol or configured by the network.

[0069] Third, if no tag signal is received within a certain timer (meaning that there is no communication demand for the tag), i.e., the timer expires, the reader will return to the specified pattern and restart the timer if it receives a tag signal before the timer expires.

[0070] In another embodiment, the method further comprises: The method further includes the first device receiving third instruction information transmitted by the second device or a network device, instructing the first device not to transmit the first signal within a target time length.

[0071] In an embodiment of the present application, a network device or a second device can dynamically instruct a first device not to transmit a signal within a certain period of time (x ms or x slots) thereafter through signaling, and the first device transmits or does not transmit the first signal based on the signaling instruction.

[0072] It should be noted that the second device may have two application scenarios: a scenario with an active transmitter and a scenario without an active transmitter, and the manner of information that the second device instructs the first device for different application scenarios may be different, which will be described in detail below.

[0073] Scenario 1: The second device has one active transmitter and one backscatter transmitter. The transmission scheme is: The second device includes transmitting a signal with an active transmitter (transmitting in a non-backscatter manner) to announce the first device's desired DTX configuration so that the second device can capture the energy transmission signal.

[0074] Scenario 2: The second device has only one backscatter transmitter. The transmission scheme includes:

[0075] 1. The first device transmits one periodic signal (e.g. DTX pattern 1).

[0076] 2. The second device uses the energy of this signal to transmit a signal to the first device, informing the first device of its desired DTX pattern 2.

[0077] Alternatively, one first device may be associated with one or more second devices and provide the first signal to multiple second devices so that the associated second devices can obtain energy by the first signal. Specifically, when one first device is associated with the multiple second devices, the first device may maintain one set of DTX configurations for each associated second device, and the first device determines the DTX configuration to be finally used according to the overlapping effect of the multiple sets of DTX configurations at each time.

[0078] Referring to FIG. 6, FIG. 6 is a flowchart of a signal transmission processing method according to an embodiment of the present application, which is used in a terminal. As shown in FIG. 6, The method includes a step 601 in which a second device obtains energy from a first signal transmitted by the first device based on a target discontinuous transmission DTX configuration of the first device.

[0083] Optionally, the step of the second device obtaining energy from a first signal transmitted by the first device based on a target discontinuous transmission DTX configuration of the first device, when the target DTX configuration includes the DTX deactivation time value, further comprises: the second device starting the DTX deactivation timer when the second device transmits a second signal; harvesting energy from a first signal transmitted by the first device in a first DTX period if the DTX deactivation timer has not timed out; and harvesting energy from a first signal transmitted by the first device in a second DTX period when the DTX deactivation timer times out.

[0084] Optionally, after the step of the second device starting the DTX deactivation timer when the second device transmits a second signal, the method further comprises: The method further includes, if the second device retransmits a second signal before the DTX deactivation timer times out, the second device restarting the DTX deactivation timer.

[0085] Optionally, the step of the second device obtaining energy from a first signal transmitted by the first device based on a target discontinuous transmission DTX arrangement of the first device comprises: When a DTX inactivation timer for the long DTX period is activated and times out, the second device harvests energy from a first signal transmitted by the first device in the short DTX period; and harvesting energy from a first signal transmitted by the first device in the long DTX cycle when a DTX deactivation timer for the N short DTX cycles has not been started within N consecutive short DTX cycles (N is a positive integer).

[0086] Optionally, the target DTX configuration comprises: DTX period, The time position at which the first device should transmit the first signal within a DTX period and the value of the parameter are included.

[0087] Optionally, before the step of the second device acquiring energy from a first signal transmitted by the first device based on a target discontinuous transmission DTX arrangement of the first device, the method further comprises: A second device determines the target DTX location based on the transmitted second instruction information; and determining, by the second device, a first preset DTX configuration as the target DTX configuration when the second device transmits a second signal; The method further includes, when the second device does not transmit the second signal within a preset time period, determining a second preset DTX configuration as the target DTX configuration.

[0088] Optionally, when the second device transmits a second signal, the first pre-set DTX arrangement is determined as the target DTX arrangement at a target time that is N time units after transmitting the second signal.

[0089] Optionally, the method further comprises: The method further includes the second device transmitting third instruction information to the first device to instruct the first device not to transmit the first signal within a target time length.
