Description

[Technical field]

[0001] [CROSS REFERENCE TO RELATED APPLICATIONS] This application claims priority to a Chinese patent application filed on April 2, 2021, bearing application number 202110362314.6 and entitled "Resource sensing method, apparatus and storage medium," the entire contents of which are incorporated herein by reference.

[0002] The present disclosure relates to the technical field of communications, and in particular to a resource sensing method, apparatus and storage medium. [Background technology]

[0003] In a 5th generation mobile communication (5G) intelligent connected automobile technology (V2X: Vehicle-to-Everything) sidelink communication system, when discontinuous reception (DRX) and partial sensing are configured simultaneously in a terminal / user equipment (UE: User Equipment), it is necessary to prevent resource collisions by partial sensing for the transmission candidate resources selected by the UE.

[0004] However, if the partial sensing timing is during a DRX off period, the UE will not be able to receive sidelink control information (SCI) and will not be able to sense the resource occupancy status during that period, which will increase the probability of resource collisions and reduce the reliability of data transmission.

[0067] 5G V2X Mode 2 adopts distributed resource scheduling, and there is no integrated scheduling by the base station, so the UE needs to determine the resource occupancy of other UEs through a sensing mechanism, and then select resources according to the sensing result. Compared with the completely random resource selection mechanism, the sensing mechanism can improve resource utilization, reduce the probability of collision, and improve system performance.

[0068] In the method of detecting resource occupancy, the first thing to be determined is the detection time. In LTE-V2X, since the V2V service transmission period can vary from 100 milliseconds (ms) to 1000 ms, if the UE needs to detect all resource occupancy, the detection time should be 1000 ms.

[0069] In the resource selection method for pedestrian-user equipment (P-UE), one very important consideration is the power consumption of P-UE. One important prerequisite is that P-UE does not need to receive data transmitted from vehicle user equipment (V-UE), and P-UE only transmits data. UE senses the reserved resources of other UEs through a partial sensing mechanism in the resource sensing window, and determines the available candidate resources in the resource selection window after eliminating the conflicting resources.

[0070] A schematic diagram showing a resource selection method for partial sensing is shown in Figure 1. As shown in Figure 1, the P-UE determines the minimum value of Y, which is the number of candidate subframes, based on the setting of the upper layer parameter minNumCAndidateSF-r14, and determines the positions of the Y subframes in the resource selection window by itself.

[0071] In a discontinuous reception (DRX) system, the UE only needs to receive at certain times, and does not need to receive all the time. The UE constantly monitors data reception, which greatly increases the UE's power consumption. DRX achieves the purpose of energy saving by preventing the UE from monitoring continuously.

[0072] Figure 2 is a schematic diagram showing a DRX cycle. As shown in Figure 2, during the DRX duration (on) in one DRX cycle, the UE monitors and receives data, the duration of the DRX cycle is DRX_on Duration Timer, and during the DRX off time (off), the UE stops monitoring to save power consumption, and the off time of the DRX cycle is DRX_Inactivity Timer. For a transmitting terminal (TxUE: Transmit User Equipment) and a receiving terminal (RxUE: Receive User Equipment) with DRX configured, the DRX settings of both should be consistent, that is, the DRX on of TxUE and the DRX on of RxUE should be consistent.

[0073] In the existing 5G V2X Mode 2 system, the UE reception setting does not consider energy saving by DRX, and no partial sensing mechanism is introduced. However, when the UE performs energy saving for the reception mode by DRX and the UE performs resource allocation by partial sensing, the sensing timing of partial sensing may be within DRX off, so that SCI cannot be received and sensing operation cannot be performed. Due to lack of monitoring of candidate resources, the resource occupancy status during the DRX off period may not be sensed, which may cause resource collision in the candidate resources and reduce the reliability of data transmission.

[0074] In the embodiment of the present disclosure, the sensing timing is a time period or a time window, within which a UE determines the resource occupation status of other UEs by receiving SCI.

[0075] The embodiments of the present disclosure provide a resource sensing method, device, and storage medium. In order to avoid a situation where the sensing timing of partial sensing is within DRX off, and the SCI within the sensing timing cannot be received due to the DRX setting, and the resource occupancy status cannot be monitored, and resource collision occurs, when the sensing timing of partial sensing is within DRX off, continuous sensing is performed for a certain period in the subsequent DRX on. For periodic service transmission, the duration of continuous sensing can be adjusted to avoid the collision problem of undetected resources. For non-periodic service transmission, continuous sensing is performed for a certain period to expand the sensing range and reduce the probability of resource collision.

[0076] In order to clarify the objectives, technical solutions and advantages of the embodiments of the present disclosure, the technical solutions of the embodiments of the present disclosure will be described below clearly and completely with reference to the drawings in the embodiments of the present disclosure. Of course, the described embodiments are only some embodiments of the present disclosure, and are not all embodiments. Based on the embodiments in the present disclosure, all other embodiments obtained by those skilled in the art without creative labor belong to the scope of protection of the present disclosure.

[0077] 3 is a flowchart of a resource sensing method according to an embodiment of the present disclosure. As shown in FIG. 3, in the resource sensing method according to an embodiment of the present disclosure, the execution body may be a terminal. The method includes the following steps 301 and 302:

[0078] In step 301, it is determined whether the current sensing timing completely overlaps with the duration of the current discontinuous reception (DRX) period.

[0079] Specifically, Figure 4 is a schematic diagram illustrating a relationship between a current sensing timing and a current DRX cycle according to an embodiment of the present disclosure. As shown in Figure 4, in a 5G V2X system, when a UE configures DRX to perform energy saving for a receiving manner and the UE performs resource allocation through partial sensing, the relationship between the current sensing timing of the UE and the current DRX cycle can be classified into the following four situations: The current sensing timing in FIG. 4(a) completely overlaps with the duration of the current DRX period; and A part of the current sensing timing in FIG. 4(b) overlaps with the duration of the current DRX period, and a remaining part of the current sensing timing overlaps with the off-time of the current DRX period; A part of the current sensing timing in FIG. 4(c) overlaps with the off-time of the current DRX period, and a remaining part of the current sensing timing overlaps with the duration of the next DRX period; The current sensing timing in FIG. 4(d) completely overlaps with the off-time of the current DRX period.

[0080] When the UE performs partial sensing, it first determines whether the current sensing timing completely overlaps with the duration of the current DRX period, i.e., whether the situation as shown in FIG. 4(a) occurs.

[0081] A specific method for making this determination can be based on the relationship between the start point of the timer for the current sensing timing, the duration of the timer for the current sensing timing, the start point of the timer for the duration of the DRX cycle, the duration of the timer for the DRX cycle, and the duration of the timer for the off time of the DRX cycle.

[0082] For example, if the start point of the current sensing timing timer is 0, the length of the current sensing timing timer is 20 ms, the start point of the current DRX period duration timer is 0, the length of the DRX period duration timer is 50 ms, and the length of the DRX period off-time timer is 50 ms, it can be determined that the current sensing timing completely overlaps with the current DRX period duration.

[0083] In step 302, if the current sensing timing does not completely overlap with the duration of the current DRX period, resource sensing is performed in a target time period within the duration of the next DRX period.

[0084] Specifically, the UE determines whether the current sensing timing completely overlaps with the duration of the current DRX period, and then performs resource sensing based on the determination result.

[0085] When the current sensing timing completely overlaps with the duration of the current DRX period, i.e., the situation in (a) of Figure 4 occurs, the UE can receive the SCI within the current sensing timing, and at this time, the UE performs resource sensing based on the SCI received within the current sensing timing.

[0086] If the current sensing timing does not completely overlap with the duration of the current DRX period, i.e., if the situation in (b), (c), or (d) of Figure 4 occurs, resource sensing is performed in a target time period within the duration of the next DRX period.

[0087] The target time period is a period of continuous sensing, and the start time and / or length of the target time period may be set by the network side, may be predefined by a protocol, or may be determined by the UE.

[0088] In the resource sensing method according to an embodiment of the present disclosure, when the sensing timing of partial sensing does not completely overlap with the duration of a DRX period, continuous sensing is performed for a certain period within the duration of the next DRX period, thereby improving the reliability of data transmission.

[0089] Optionally, the situation where the current sensing timing does not completely overlap with the duration of the current DRX period may be A portion of the current sensing timing overlaps with the duration of the current DRX period, and a remaining portion of the current sensing timing overlaps with the off-time of the current DRX period.

[0090] Specifically, as shown in FIG. 4(b), in an embodiment of the present disclosure, the situation in which the current sensing timing does not completely overlap with the duration of the current DRX period is as follows: A portion of the current sensing timing overlaps with the duration of the current DRX period, and a remaining portion of the current sensing timing overlaps with the off-time of the current DRX period.

[0091] For example, if the start point of the current sensing timing timer is 45 ms, the length of the current sensing timing timer is 20 ms, the start point of the current DRX period duration timer is 0, the length of the DRX period duration timer is 50 ms, and the length of the DRX period off-time timer is 50 ms, then the first 5 ms of the current sensing timing overlaps with the current DRX period duration, so the UE can receive SCI and can perform resource sensing, and the last 15 ms of the current sensing timing overlaps with the current DRX period off-time, so the UE cannot receive SCI and cannot perform resource sensing.

[0092] In a resource sensing method according to an embodiment of the present disclosure, when a part of a current sensing timing overlaps with the duration of a current DRX cycle and a remaining part of the current sensing timing overlaps with an off-time of the current DRX cycle, continuous sensing is performed for a certain period within the duration of the next DRX cycle, thereby improving the reliability of data transmission.

[0093] Optionally, the situation where the current sensing timing does not completely overlap with the duration of the current DRX period may be This includes that the current sensing timing completely overlaps with the off-time of the current DRX period.

[0094] Specifically, as shown in FIG. 4(d), in an embodiment of the present disclosure, the situation in which the current sensing timing does not completely overlap with the duration of the current DRX period is as follows: This includes that the current sensing timing completely overlaps with the off-time of the current DRX period.

[0095] For example, if the start point of the current sensing timing timer is 55 ms, the length of the current sensing timing timer is 20 ms, the start point of the current DRX period duration timer is 0, the length of the DRX period duration timer is 50 ms, and the length of the DRX period off-time timer is 50 ms, then the current sensing timing completely overlaps with the current DRX period off-time, and the UE cannot receive SCI and cannot perform resource sensing.

[0096] The resource sensing method according to an embodiment of the present disclosure improves the reliability of data transmission by performing continuous sensing for a certain period within the duration of the next DRX period when the current sensing timing completely overlaps with the off-time of the current DRX period.

[0097] Optionally, the situation where the current sensing timing does not completely overlap with the duration of the current DRX period may be The present sensing timing includes a portion of the current sensing timing overlapping with the off-time of the current DRX period, and a remaining portion of the current sensing timing overlapping with the duration of the next DRX period.

[0098] Specifically, as shown in FIG. 4(c), in an embodiment of the present disclosure, the situation in which the current sensing timing does not completely overlap with the duration of the current DRX period is as follows: The present sensing timing includes a portion of the current sensing timing overlapping with the off-time of the current DRX period, and a remaining portion of the current sensing timing overlapping with the duration of the next DRX period.

[0099] For example, if the start point of the current sensing timing timer is 95 ms, the length of the current sensing timing timer is 20 ms, the start point of the current DRX period duration timer is 0, the length of the DRX period duration timer is 50 ms, and the length of the DRX period off-time timer is 50 ms, then the first 5 ms of the current sensing timing overlaps with the off-time of the current DRX period, so the UE cannot receive SCI and cannot perform resource sensing; and the last 15 ms of the current sensing timing overlaps with the duration of the next DRX period, so the UE can receive SCI and can perform resource sensing.

[0100] In a resource sensing method according to an embodiment of the present disclosure, when a part of a current sensing timing overlaps with an off-time of a current DRX cycle and a remaining part of the current sensing timing overlaps with a duration of a next DRX cycle, continuous sensing is performed for a certain period within the duration of the next DRX cycle, thereby improving the reliability of data transmission.

[0101] Optionally, before determining whether the current sensing timing completely overlaps with the duration of the current DRX period, receiving a first configuration message transmitted from a network device, the first configuration message including a start position of the target time period; Or, The start position of the target time period is preset; Or, Before performing resource sensing in the target time period within the duration of the next DRX period, The method further includes determining a start position of the target time period.

[0102] Specifically, in an embodiment of the present disclosure, the start position of the target time period is set by the network side, and before the UE determines whether the current sensing timing completely overlaps with the duration of the current discontinuous reception (DRX) period, the network side device sends a first configuration message to the UE, where the first configuration message includes the start position of the target time period.

[0103] The UE receives a first configuration message sent from the network device, and analyzes the starting position of the target time period from the first configuration message.

[0104] The first configuration message may be borne by a Radio Resource Control (RRC) message, a Media Access Control Control Element (MAC CE) message, or a Downlink Control Information (DCI) message.

[0105] For example, the network side device transmits a DCI message to the UE, and the DCI message includes a position indicating that the start position of the target time period is 30 ms from the start of the duration of the next DRX period.

[0106] Also, for example, the network side device transmits a MAC CE message to the UE, and the MAC CE message includes information that the start position of the target time period is 35 ms from the start of the duration of the next DRX period.

[0107] The resource sensing method according to an embodiment of the present disclosure can improve flexibility and be applicable to different scenarios by setting the start position of the target time period by the network side.

[0108] In an embodiment of the present disclosure, the start position of the target time period may be preset, i.e., predefined by a protocol.

[0109] For example, the start position of the target time period is predefined by the protocol to be 30 ms from the start of the duration of the next DRX period.

[0110] Also, for example, the start position of the target time period is predefined by the protocol to be 35 ms from the start point of the duration of the next DRX cycle.

[0111] The resource sensing method according to the embodiment of the present disclosure predefines the start position of the target time slot through a protocol, thereby reducing signaling overhead.

[0112] In an embodiment of the present disclosure, the starting position of the target time period may be determined by the UE.

[0113] The UE may determine the starting position of the target time period based on its synchronization accuracy.The UE may determine the starting position of the target time period based on the clock speed of its central processing unit (CPU).

[0114] For example, if the synchronization accuracy of the UE is better than 1 ms, the start position of the target time period and the start position of the duration of the next DRX period are identical.

[0115] If the UE synchronization accuracy is less than 1 ms, the start of the target time period is 2 ms from the start of the next DRX period duration.

[0116] The resource sensing method according to an embodiment of the present disclosure enables the UE to determine the starting position of the target time period based on its own circumstances, thereby further improving the reliability of data transmission.

[0117] Optionally, the start position and the start position of the next DRX period duration are identical.

[0118] Specifically, in an embodiment of the present disclosure, the start position of the target time period and the start position of the duration of the next DRX period are the same.

[0119] For example, if the start point of the current sensing timing timer is 55 ms, the length of the current sensing timing timer is 20 ms, the start point of the current DRX period duration timer is 0, the length of the DRX period duration timer is 50 ms, and the length of the DRX period off-time timer is 50 ms, then the current sensing timing completely overlaps with the current DRX period off-time, and the UE cannot receive SCI and cannot perform resource sensing.

[0120] The UE performs continuous sensing at the beginning of the next DRX period duration, i.e. 100 ms.

[0121] For example, if the start point of the current sensing timing timer is 95 ms, the length of the current sensing timing timer is 20 ms, the start point of the current DRX cycle duration timer is 0, the length of the DRX cycle duration timer is 50 ms, and the length of the DRX cycle off-time timer is 50 ms, the first 5 ms of the current sensing timing overlaps with the off-time of the current DRX cycle, and the UE cannot receive SCI and cannot perform resource sensing.

[0122] The UE performs continuous sensing at the beginning of the next DRX period duration, i.e. 100 ms.

[0123] In the resource sensing method according to the embodiment of the present disclosure, the start position of the target time period and the start position of the duration of the next DRX period are the same, so that the UE can quickly perform resource sensing.

[0124] Optionally, the start position is a target fixed position within the duration of the next DRX period.

[0125] Specifically, in an embodiment of the present disclosure, the starting position of the target time period is a target fixed position within the duration of the next DRX period.

[0126] The target fixation position may be a position 10 ms from the start of the duration of the next DRX cycle, may be a position 20 ms from the start of the duration of the next DRX cycle, or may be a midpoint of the duration of the next DRX cycle.

[0127] For example, if the start point of the current sensing timing timer is 55 ms, the length of the current sensing timing timer is 20 ms, the start point of the current DRX period duration timer is 0, the length of the DRX period duration timer is 50 ms, and the length of the DRX period off-time timer is 50 ms, then the current sensing timing completely overlaps with the current DRX period off-time, and the UE cannot receive SCI and cannot perform resource sensing.

[0128] The UE performs continuous sensing for 10 ms from the start of the next DRX period duration, i.e., 110 ms.

[0129] For example, if the start point of the current sensing timing timer is 95 ms, the length of the current sensing timing timer is 20 ms, the start point of the current DRX period duration timer is 0, the length of the DRX period duration timer is 50 ms, and the length of the DRX period off-time timer is 50 ms, the first 5 ms of the current sensing timing overlaps with the off-time of the current DRX period, and the UE cannot receive SCI and cannot perform resource sensing.

[0130] The UE performs continuous sensing at the midpoint after the start of the next DRX period duration, ie 125 ms.

[0131] In the resource sensing method according to an embodiment of the present disclosure, the start position of the target time period is a target fixed position for the duration of the next DRX period, thereby eliminating the effect of time desynchronization and further improving the reliability of data transmission.

[0132] Optionally, for periodic services, the length of the target window is equal to or greater than the maximum perceived period if service delays can be accommodated.

[0133] Specifically, in an embodiment of the present disclosure, for a periodic service, if the service delay can be guaranteed, the length of the target time window is equal to or greater than the maximum sensing period.

[0134] For example, if the maximum sensing period is 20 ms, then for a periodic service, the length of the target window is set to 20 ms if the service delay can be accommodated.

[0135] Also, for example, if the maximum sensing period is 20 ms, the length of the target time slot is set to 25 ms if the service delay can be ensured for a periodic service.

[0136] For periodic service transmissions, the collision problem of unsensed resources can be avoided by adjusting the duration of continuous sensing.

[0137] In the resource sensing method according to an embodiment of the present disclosure, when the service delay can be ensured for a periodic service, the length of the target time period is equal to or greater than the maximum sensing period, thereby further improving the reliability of data transmission.

[0138] Optionally, for periodic services, if the service delay cannot be guaranteed, the end of the target time window does not exceed the end of the duration of the next DRX period.

[0139] Specifically, in an embodiment of the present disclosure, for a periodic service, if 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 period.

[0140] For example, for a periodic service, if the service delay cannot be ensured, the start point of the current sensing timing timer is 55 ms, the length of the current sensing timing timer is 20 ms, the start point of the current DRX period duration timer is 0, the length of the DRX period duration timer is 50 ms, and the length of the DRX period off-time timer is 50 ms, then the current sensing timing completely overlaps with the current DRX period off-time, and the UE cannot receive SCI and cannot perform resource sensing.

[0141] The UE performs resource sensing during a target time period within the duration of the next DRX period, where the end position of the target time period does not exceed 150 ms.

[0142] For periodic service transmissions, the collision problem of unsensed resources can be avoided by adjusting the duration of continuous sensing.

[0143] The resource sensing method according to an embodiment of the present disclosure further improves the reliability of data transmission for periodic services, because 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 period.

[0144] Optionally, for aperiodic services, the end of the target time period does not exceed the end of the duration of the next DRX period.

[0145] Specifically, in an embodiment of the present disclosure, for a non-periodic service, 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 period.

[0146] For example, for a periodic service, if the start point of the current sensing timing timer is 55 ms, the length of the current sensing timing timer is 20 ms, the start point of the current DRX period duration timer is 0, the length of the DRX period duration timer is 50 ms, and the length of the DRX period off-time timer is 50 ms, then the current sensing timing completely overlaps with the current DRX period off-time, and the UE cannot receive SCI and cannot perform resource sensing.

[0147] The UE then performs resource sensing in a target time period within the duration of the next DRX period, where the end position of the target time period does not exceed 150 ms.

[0148] For non-periodic service transmissions, continuous sensing over a period of time increases the sensing range and reduces the probability of resource collision.

[0149] The resource sensing method according to the embodiment of the present disclosure further improves the reliability of data transmission for aperiodic services because the end position of the target time period does not exceed the end position of the duration of the next DRX period.

[0150] It is also necessary to explain, First, the DRX period may be smaller than the partial sensing window.

[0151] 5 is a schematic diagram showing the relationship between the DRX cycle and the partial sensing window according to an embodiment of the present disclosure. As shown in FIG. 5, when the interval of the sensing timing in the partial sensing window is an integer multiple of the DRX cycle, each sensing timing of the partial sensing must be within the DRX on period.

[0152] 6 is a second schematic diagram showing the relationship between the DRX cycle and the partial sensing window according to an embodiment of the present disclosure. As shown in FIG. 6, when the interval of the sensing timing in the partial sensing window is not an integer multiple of the DRX cycle, sensing is performed at the partial sensing timing that overlaps with the DRX on period, and sensing is not performed at the partial sensing timing that overlaps with the DRX off period. When DRX off ends and the DRX on stage begins, continuous sensing is performed for a certain period.

[0153] Second, the DRX period may be larger than the partial sensing window.

[0154] 7 is a third schematic diagram showing the relationship between the DRX cycle and the partial sensing window according to an embodiment of the present disclosure. As shown in FIG. 7, when the sensing timing in the partial sensing window is partially within the DRX on period, sensing is performed at the sensing timing of partial sensing within the DRX on period, and sensing is not performed at the sensing timing within the DRX off period. When the DRX off time ends and the DRX on stage begins, continuous sensing is performed for a certain period of time.

[0155] 8 is a fourth schematic diagram showing the relationship between the DRX cycle and the partial sensing window according to an embodiment of the present disclosure. As shown in FIG. 8, when all sensing timings in the partial sensing window are in the DRX on period, each sensing timing of the partial sensing is sensed within the DRX on period.
