Description

Technical Field

[0002] In the 5th generation mobile communication (5G) intelligent connected vehicle technology (Vehicle-to-Everything, V2X) direct link communication system, when the terminal / user equipment (User Equipment, UE) is configured with both discontinuous reception (DRX) and partial sensing, the candidate resources selected by the UE for transmission need to eliminate resource collision through partial sensing.

[0003] However, if the partial sensing is performed during the DRX off period, the UE will not be able to receive the sidelink control information (SCI) and will not be able to perceive the resource occupancy during this period, which will increase the probability of resource collision and reduce the reliability of data transmission.

[0096] 5G V2X Mode 2 (Mode 2) uses distributed resource scheduling. Since there is no unified scheduling by the base station, the UE needs to determine the resource occupancy of other UEs through the perception mechanism and select resources based on the perception results. Compared with a completely random resource selection mechanism, the perception mechanism can improve resource utilization, reduce collision probability, and improve system performance.

[0097] In the resource occupancy status perception method, the first thing that needs to be determined is the perception time. In LTE-V2X, since the V2V service transmission cycle is variable from 100 milliseconds (ms) to 1000ms, if the UE needs to perceive all resource occupancy states, the perception time should be 1000ms.

[0098] In the resource selection method for pedestrian terminals (Pedestrian-User Equipment, P-UE), a very important consideration is the power consumption of P-UE. An important prerequisite is that P-UE does not need to receive data sent by vehicle terminals (Vehicle User Equipment, V-UE), and P-UE only sends data. UE perceives other UE reserved resources through partial perception mechanism within the resource perception window, and determines the available candidate resources in the resource selection window after excluding collision resources.

[0099] Figure 1 is a schematic diagram of the partial-aware resource selection method, such as Figure 1 As shown. The P-UE determines the minimum value of the number of candidate subframes Y according to the high-level parameter minNumCAndidateSF-r14 configuration, and determines the position of the Y subframes in the resource selection window by itself. The resource occupancy result on the subframe determines the current subframe The set of k values ​​is configured through the high-level parameter gapCandidateSensing-r14, and k corresponds to the position where the kth bit of the high-level parameter gapCandidateSensing-r14 is 1.

[0100] In a discontinuous reception (DRX) system, the UE only needs to receive data at some times, not all the time. The UE's constant monitoring of data reception will cause the UE to consume a lot of power. DRX enables the UE to monitor discontinuously, thereby achieving energy saving.

[0101] Figure 2 It is a schematic diagram of the DRX cycle, such as Figure 2As shown, in a DRX cycle, the UE monitors and receives data during the DRX duration (on), and the duration of the DRX cycle is the DRX_on Duration Timer. During the DRX off time (off), the UE stops monitoring to save power consumption, and the off time of the DRX cycle is the DRX_Inactivity Timer. For the transmitting terminal (Transmit User Equipment, TxUE) and the receiving terminal (Receive User Equipment, RxUE) configured with DRX, the DRX configuration of the two should be consistent, that is, the DRX on of the TxUE is aligned with the DRX on of the RxUE.

[0102] In the existing 5G V2X Mode 2 system, the UE's receiving configuration does not consider energy saving through DRX, nor does it introduce a partial sensing mechanism. However, if the UE uses DRX to save energy on the receiving mode and the UE allocates resources through partial sensing, the sensing timing of partial sensing may be during DRX off, resulting in the inability to receive SCI and perform sensing operations. Due to the lack of monitoring of candidate resources, the resource occupancy during the DRX off period may not be sensed, resulting in resource collisions among candidate resources and reduced reliability of data transmission.

[0103] The perception opportunity involved in the embodiment of the present application is a time period or a time window. During the perception opportunity, the UE determines the resource occupancy of other UEs by receiving the SCI.

[0104] The embodiments of the present application provide a resource sensing method, device and storage medium. To avoid the situation where the sensing opportunity of partial sensing is within DRX off, which may cause resource collision due to the inability to receive the SCI within the sensing opportunity and monitor the resource occupancy at that time because of the DRX configuration, when the sensing opportunity of partial sensing is within DRX off, continuous sensing is performed for a period of time in the subsequent DRX on. For periodic service transmission, the problem of unaware resource collision can be avoided by adjusting the duration of a period of continuous sensing. For non-periodic service transmission, the sensing range is increased and the probability of resource collision is reduced by performing continuous sensing for a period of time.

[0105] In order to make the purpose, technical solution and advantages of the embodiments of the present application clearer, the technical solution in the embodiments of the present application will be clearly and completely described below in conjunction with the drawings in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of this application.

[0106] Figure 3 is one of the flow charts of the resource perception method provided in the embodiment of the present application, such as Figure 3 As shown, an embodiment of the present application provides a resource perception method, the execution subject of which may be a terminal. The method includes:

[0107] Step 301: determine whether the current sensing opportunity completely overlaps with the duration of the current discontinuous reception DRX cycle.

[0108] Specifically, Figure 4 is a schematic diagram of the relationship between the current sensing opportunity and the current DRX cycle provided in an embodiment of the present application, such as Figure 4 As shown, in the 5G V2X system, when the UE configures DRX to save energy in the receiving mode and the UE allocates resources through partial perception, the relationship between the UE's current perception timing and the current DRX cycle includes the following four situations:

[0109] Figure 4 In (a), the current sensing opportunity completely overlaps with the duration of the current DRX cycle.

[0110] Figure 4 In (b), a portion of the current sensing opportunity overlaps with the duration of the current DRX cycle, and the rest of the current sensing opportunity overlaps with the off time of the current DRX cycle.

[0111] Figure 4 In (c), a portion of the current sensing opportunity overlaps with the off time of the current DRX cycle, and the rest of the current sensing opportunity overlaps with the duration of the next DRX cycle.

[0112] Figure 4 In (d), the current sensing timing completely overlaps with the shutdown time of the current DRX cycle.

[0113] When the UE performs partial sensing, it first determines whether the current sensing opportunity completely overlaps with the duration of the current DRX cycle, that is, whether Figure 4 The situation in (a).

[0114] The specific judgment method can be determined based on the relationship between the start time of the current perception opportunity timer, the duration of the current perception opportunity timer, the start time of the current DRX cycle duration timer, the length of the DRX cycle duration timer, and the length of the DRX cycle shutdown time timer.

[0115] For example, the start time of the timer of the current perception opportunity is 0, the duration of the current perception opportunity timer is 20ms, the start time of the timer of the current DRX cycle duration is 0, the duration of the timer of the DRX cycle duration is 50ms, and the duration of the timer of the DRX cycle shutdown time is 50ms. It can be determined that the current perception opportunity completely overlaps with the duration of the current DRX cycle.

[0116] Step 302: If the current sensing opportunity does not completely overlap with the duration of the current DRX cycle, resource sensing is performed in a target time period within the duration of the next DRX cycle.

[0117] Specifically, after determining whether the current sensing opportunity completely overlaps with the duration of the current DRX cycle, the UE performs resource sensing according to the determination result.

[0118] If the current sensing opportunity completely overlaps with the duration of the current DRX cycle, Figure 4 In case (a), the UE can receive SCI within the current sensing opportunity. At this time, the UE performs resource sensing based on the SCI received within the current sensing opportunity.

[0119] If the current sensing opportunity does not completely overlap with the duration of the current DRX cycle, Figure 4 In case (b) or (c) or (d), resource sensing is performed in the target time period within the duration of the next DRX cycle.

[0120] The target time period is a continuously perceived time period, and the starting time and / or length of the target time period may be configured by the network side, may be pre-defined by the protocol, or may be determined by the UE.

[0121] The resource sensing method provided in the embodiment of the present application performs continuous sensing for a period of time within the duration of the next DRX cycle when the sensing opportunity of partial sensing does not completely overlap with the duration of the DRX cycle, thereby improving the reliability of data transmission.

[0122] Optionally, the situation where the current sensing opportunity does not completely overlap with the duration of the current DRX cycle includes:

[0123] A portion of the current sensing opportunity overlaps with the duration of the current DRX cycle, and the rest of the current sensing opportunity overlaps with the off time of the current DRX cycle.

[0124] Specifically, if Figure 4 As shown in (b), in the embodiment of the present application, the situation where the current sensing opportunity does not completely overlap with the duration of the current DRX cycle includes:

[0125] A portion of the current sensing opportunity overlaps with the duration of the current DRX cycle, and the rest of the current sensing opportunity overlaps with the off time of the current DRX cycle.

[0126] For example, the start time of the current perception opportunity timer is 45ms, the duration of the current perception opportunity timer is 20ms, the start time of the current DRX cycle duration timer is 0, the duration of the DRX cycle duration timer is 50ms, and the duration of the DRX cycle shutdown time timer is 50ms. Then, the first 5ms of the current perception opportunity overlaps with the duration of the current DRX cycle, and the UE can receive SCI and perform resource perception. The last 15ms of the current perception opportunity overlaps with the shutdown time of the current DRX cycle, and the UE cannot receive SCI and cannot perform resource perception.

[0127] The resource sensing method provided in the embodiment of the present application performs continuous sensing for a period of time within the duration of the next DRX cycle when a part of the current sensing opportunity overlaps with the duration of the current DRX cycle and the rest of the current sensing opportunity overlaps with the shutdown time of the current DRX cycle, thereby improving the reliability of data transmission.

[0128] Optionally, the situation where the current sensing opportunity does not completely overlap with the duration of the current DRX cycle includes:

[0129] The current sensing opportunity completely overlaps with the shutdown time of the current DRX cycle.

[0130] Specifically, if Figure 4 As shown in (d), in the embodiment of the present application, the situation where the current sensing opportunity does not completely overlap with the duration of the current DRX cycle includes:

[0131] The current sensing opportunity completely overlaps with the shutdown time of the current DRX cycle.

[0132] For example, the start time of the current perception opportunity timer is 55ms, the duration of the current perception opportunity timer is 20ms, the start time of the current DRX cycle duration timer is 0, the duration of the DRX cycle duration timer is 50ms, and the duration of the DRX cycle shutdown time timer is 50ms. Then the current perception opportunity completely overlaps with the current DRX cycle shutdown time, and the UE cannot receive SCI and cannot perform resource perception.

[0133] The resource sensing method provided in the embodiment of the present application performs continuous sensing for a period of time within the duration of the next DRX cycle when the current sensing opportunity completely overlaps with the shutdown time of the current DRX cycle, thereby improving the reliability of data transmission.

[0134] Optionally, the situation where the current sensing opportunity does not completely overlap with the duration of the current DRX cycle includes:

[0135] A portion of the current sensing opportunity overlaps with the off time of the current DRX cycle, and the rest of the current sensing opportunity overlaps with the duration of the next DRX cycle.

[0136] Specifically, if Figure 4 As shown in (c), in the embodiment of the present application, the situation where the current sensing opportunity does not completely overlap with the duration of the current DRX cycle includes:

[0137] A portion of the current sensing opportunity overlaps with the off time of the current DRX cycle, and the rest of the current sensing opportunity overlaps with the duration of the next DRX cycle.

[0138] For example, the start time of the current perception opportunity timer is 95ms, the duration of the current perception opportunity timer is 20ms, the start time of the current DRX cycle duration timer is 0, the duration of the DRX cycle duration timer is 50ms, and the duration of the DRX cycle shutdown time timer is 50ms. Then, the first 5ms of the current perception opportunity overlaps with the shutdown time of the current DRX cycle, and the UE cannot receive SCI and cannot perform resource perception. The second 15ms of the current perception opportunity overlaps with the duration of the next DRX cycle, and the UE can receive SCI and can perform resource perception.

[0139] The resource sensing method provided in the embodiment of the present application performs continuous sensing for a period of time within the duration of the next DRX cycle when a part of the current sensing opportunity overlaps with the shutdown time of the current DRX cycle and the rest of the current sensing opportunity overlaps with the duration of the next DRX cycle, thereby improving the reliability of data transmission.

[0140] Optionally, before determining whether the current sensing opportunity completely overlaps with the duration of the current discontinuous reception DRX cycle, the step further includes:

[0141] Receiving a first configuration message sent by a network device; the first configuration message includes a starting position of the target time period;

[0142] or,

[0143] The starting position of the target time period is preconfigured;

[0144] or,

[0145] Before performing resource sensing in the target time period within the duration of the next DRX cycle, the method further includes:

[0146] The starting position of the target time period is determined.

[0147] Specifically, in an embodiment of the present application, the starting position of the target time period is configured by the network side, and before the UE determines whether the current perception opportunity completely overlaps with the duration of the current discontinuous reception DRX cycle, the network side device sends a first configuration message to the UE; the first configuration message includes the starting position of the target time period.

[0148] The UE receives a first configuration message sent by the network device, and parses the first configuration message to obtain a start position of the target time period.

[0149] The first configuration message may be carried by a radio resource control (Radio Resource Control, RRC) message, by a media access control control element (Media Access Control Control Element, MACCE) message, or by a downlink control information (Downlink Control Information, DCI) message.

[0150] For example, the network side device sends a DCI message to the UE, and the DCI message includes a start position of the target time period as 30 ms after the start time of the duration of the next DRX cycle.

[0151] For another example, the network side device sends a MAC CE message to the UE, and the MAC CE message includes that the starting position of the target time period is 35 ms after the starting time of the duration of the next DRX cycle.

[0152] The resource perception method provided in the embodiment of the present application increases flexibility by configuring the starting position of the target time period on the network side, and can be applied to different scenarios.

[0153] In the embodiment of the present application, the starting position of the target time period may also be pre-configured, that is, pre-defined by the protocol.

[0154] For example, the starting position of the target time period is predefined by the protocol as 30 ms after the starting time of the duration of the next DRX cycle.

[0155] For another example, the starting position of the target time period is predefined by the protocol as 35 ms after the starting time of the duration of the next DRX cycle.

[0156] The resource perception method provided in the embodiment of the present application predefines the starting position of the target time period through a protocol, thereby reducing signaling overhead.

[0157] In the embodiment of the present application, the starting position of the target time period may also be determined by the UE.

[0158] The UE may determine the starting position of the target time period according to its own synchronization accuracy. The UE may also determine the starting position of the target time period according to the main frequency of its own central processing unit (CPU).

[0159] For example, when the synchronization accuracy of the UE is higher than 1 microsecond, the starting position of the target time period is the same as the starting position of the duration of the next DRX cycle.

[0160] When the synchronization accuracy of the UE is less than 1 microsecond, the starting position of the target time period is 2 ms after the starting position of the duration of the next DRX cycle.

[0161] The resource perception method provided in the embodiment of the present application enables the UE to determine the starting position of the target time period according to its own situation, thereby further improving the reliability of data transmission.

[0162] Optionally, the starting position is the same as the starting position of the duration of the next DRX cycle.

[0163] Specifically, in the embodiment of the present application, the starting position of the target time period is the same as the starting position of the duration of the next DRX cycle.

[0164] For example, the start time of the current perception opportunity timer is 55ms, the duration of the current perception opportunity timer is 20ms, the start time of the current DRX cycle duration timer is 0, the duration of the DRX cycle duration timer is 50ms, and the duration of the DRX cycle shutdown time timer is 50ms. Then the current perception opportunity completely overlaps with the current DRX cycle shutdown time, and the UE cannot receive SCI and cannot perform resource perception.

[0165] The UE performs continuous sensing at the start position of the duration of the next DRX cycle, that is, 100 ms.

[0166] For another example, the start time of the current perception opportunity timer is 95ms, the duration of the current perception opportunity timer is 20ms, the start time of the current DRX cycle duration timer is 0, the duration of the DRX cycle duration timer is 50ms, and the duration of the DRX cycle shutdown time timer is 50ms. Then, the first 5ms of the current perception opportunity overlaps with the shutdown time of the current DRX cycle, and the UE cannot receive SCI and cannot perform resource perception.

[0167] The UE performs continuous sensing at the start position of the duration of the next DRX cycle, that is, 100 ms.

[0168] In the resource sensing method provided in the embodiment of the present application, the starting position of the target time period is the same as the starting position of the duration of the next DRX cycle, so that the UE can perform resource sensing as quickly as possible.

[0169] Optionally, the starting position is a target fixed position within the duration of the next DRX cycle.

[0170] Specifically, in the embodiment of the present application, the starting position of the target time period is a target fixed position within the duration of the next DRX cycle.

[0171] The target fixed position may be 10 ms after the start position of the duration of the next DRX cycle, or 20 ms after the start position of the duration of the next DRX cycle, or a middle position of the duration of the next DRX cycle.

[0172] For example, the start time of the current perception opportunity timer is 55ms, the duration of the current perception opportunity timer is 20ms, the start time of the current DRX cycle duration timer is 0, the duration of the DRX cycle duration timer is 50ms, and the duration of the DRX cycle shutdown time timer is 50ms. Then the current perception opportunity completely overlaps with the current DRX cycle shutdown time, and the UE cannot receive SCI and cannot perform resource perception.

[0173] The UE performs continuous sensing 10 ms after the start position of the duration of the next DRX cycle, that is, 110 ms.

[0174] For another example, the start time of the current perception opportunity timer is 95ms, the duration of the current perception opportunity timer is 20ms, the start time of the current DRX cycle duration timer is 0, the duration of the DRX cycle duration timer is 50ms, and the duration of the DRX cycle shutdown time timer is 50ms. Then, the first 5ms of the current perception opportunity overlaps with the shutdown time of the current DRX cycle, and the UE cannot receive SCI and cannot perform resource perception.

[0175] The UE performs continuous sensing at the middle position after the start position of the duration of the next DRX cycle, that is, 125 ms.

[0176] In the resource perception method provided in the embodiment of the present application, the starting position of the target time period is the target fixed position of the duration of the next DRX cycle, which can eliminate the influence of time asynchrony and further improve the reliability of data transmission.

[0177] Optionally, for periodic services, while ensuring service delay, the length of the target time period is not less than the maximum perception period.

[0178] Specifically, in an embodiment of the present application, for periodic services, while ensuring service latency, the length of the target time period is not less than the maximum perception period.

[0179] For example, if the maximum sensing period is 20 ms, then for periodic services, the length of the target time period is set to 20 ms while ensuring the service delay.

[0180] For another example, if the maximum sensing period is 20 ms, then for periodic services, while ensuring service latency, the length of the target time period is set to 25 ms.

[0181] For periodic service transmission, the problem of unperceived resource collision can be avoided by adjusting the duration of continuous perception.

[0182] The resource perception method provided in the embodiment of the present application, for periodic services, while being able to ensure service delay, the length of the target time period is not less than the maximum perception period, thereby further improving the reliability of data transmission.

[0183] Optionally, for periodic services, when service delay cannot be guaranteed, the end position of the target time period does not exceed the end position of the duration of the next DRX cycle.

[0184] Specifically, in an embodiment of the present application, for periodic services, when the service delay cannot be guaranteed, the end position of the target time period does not exceed the end position of the duration of the next DRX cycle.

[0185] For example, for periodic services, when the service delay cannot be guaranteed, the start time of the current perception opportunity timer is 55ms, the duration of the current perception opportunity timer is 20ms, the start time of the current DRX cycle duration timer is 0, the duration of the DRX cycle duration timer is 50ms, and the duration of the DRX cycle shutdown time timer is 50ms. Then, the current perception opportunity completely overlaps with the current DRX cycle shutdown time, and the UE cannot receive SCI and cannot perform resource perception.

[0186] The UE performs resource sensing in a target time period within the duration of the next DRX cycle, and the end position of the target time period does not exceed 150 ms.

[0187] For periodic service transmission, the problem of unperceived resource collision can be avoided by adjusting the duration of continuous perception.

[0188] The resource perception method provided in the embodiment of the present application, for periodic services, when the service delay cannot be guaranteed, the end position of the target time period does not exceed the end position of the duration of the next DRX cycle, thereby further improving the reliability of data transmission.

[0189] Optionally, for non-periodic services, the end position of the target time period does not exceed the end position of the duration of the next DRX cycle.

[0190] Specifically, in the embodiment of the present application, for non-periodic services, the continuous sensing time is as short as possible, and the end position of the target time period does not exceed the end position of the duration of the next DRX cycle.

[0191] For example, for periodic services, the start time of the current perception opportunity timer is 55ms, the duration of the current perception opportunity timer is 20ms, the start time of the current DRX cycle duration timer is 0, the duration of the DRX cycle duration timer is 50ms, and the duration of the DRX cycle shutdown time timer is 50ms. The current perception opportunity completely overlaps with the current DRX cycle shutdown time, and the UE cannot receive SCI and cannot perform resource perception.

[0192] The UE performs resource sensing in a target time period within the duration of the next DRX cycle, and the end position of the target time period does not exceed 150 ms.

[0193] For non-periodic service transmission, continuous sensing for a period of time increases the sensing range and reduces the probability of resource collision.

[0194] The resource perception method provided in the embodiment of the present application, for non-periodic services, the end position of the target time period does not exceed the end position of the duration of the next DRX cycle, thereby further improving the reliability of data transmission.

[0195] In addition, it should be noted that:

[0196] 1. The DRX cycle may be smaller than the partial perception window.

[0197] Figure 5 This is one of the schematic diagrams of the relationship between the DRX cycle and the size of the partial perception window provided in the embodiment of the present application, such as Figure 5 As shown, when the sensing opportunity interval in the partial sensing window is an integer multiple of the DRX cycle, each sensing opportunity of the partial sensing must be sensed within the DRX on period.

[0198] Figure 6 This is the second schematic diagram of the relationship between the DRX cycle and the size of the partial perception window provided in the embodiment of the present application, such as Figure 6As shown, when the sensing opportunity interval in the partial sensing window is not an integer multiple of the DRX cycle, the sensing opportunities of the partial sensing that overlap with the DRX on period are sensed, and the sensing opportunities of the partial sensing that overlap with the DRX off period are not sensed. After the DRX off period ends, the DRX on phase is entered for a period of continuous sensing.

[0199] Second, the DRX cycle can be larger than the partial perception window.

[0200] Figure 7 This is the third schematic diagram of the relationship between the DRX cycle and the size of the partial perception window provided in the embodiment of the present application, such as Figure 7 As shown, when the sensing opportunities in the partial sensing window partially fall in the DRX on period, the sensing opportunities that fall in the DRX on period are sensed, and the sensing opportunities that fall in the DRX off period are not sensed. After the DRX off time ends, the DRX on phase is entered for continuous sensing for a period of time.

[0201] Figure 8 This is a fourth schematic diagram of the relationship between the DRX cycle and the size of the partial perception window provided in an embodiment of the present application, such as Figure 8 As shown, when all the sensing opportunities in the partial sensing window fall within the DRX on period, each sensing opportunity of the partial sensing is sensed within the DRX on period.
