Description

Technical Field

[0001] The present application relates to the field of wireless communication technology, and in particular to a resource sensing method and terminal device. Background Art

[0002] V2X (Vehicle to Everything) focuses on vehicle-to-everything (V2X) messaging solutions. In LTE (Long Term Evolution) V2X technology, user equipment (UE) monitors the periodic resource reservations of other UEs using PBPS (Period-based Partial Sensing). This eliminates candidate resources already reserved by other UEs, thereby reducing the probability of resource collisions.

[0003] In the process of transitioning from LTE V2X technology to NR (New Radio Access Technology) V2X technology, CPS (Contiguous Partial Sensing) has been added to avoid collisions with aperiodic reserved resources, thereby reducing the probability of collisions with aperiodic reserved resources. However, if both PBPS and CPS are used for resource sensing in all cases, the UE's power consumption will increase. Summary of the Invention

[0100] The specific embodiments of the present application are described in detail below with reference to the accompanying drawings. It should be understood that the specific embodiments described herein are only used to illustrate and explain the present application and are not intended to limit the present application.

[0101] It should be noted that the terms "first" and "second" in the embodiments of this application are used to distinguish similar objects, rather than to describe a specific order or precedence. The term "and / or" in the embodiments of this application describes the association relationship between associated objects, indicating that three possible relationships exist. For example, "A and / or B" can represent: A exists alone, A and B exist simultaneously, and B exists alone. The character " / " generally indicates that the associated objects are in an "or" relationship.

[0102] The network architecture and business scenarios described in the embodiments of the present application are intended to more clearly illustrate the technical solutions of the embodiments of the present application, and do not constitute a limitation on the technical solutions provided in the embodiments of the present application. Ordinary technicians in this field will know that with the evolution of network architecture and the emergence of new business scenarios, the technical solutions provided in the embodiments of the present application are also applicable to similar technical problems.

[0103] Figure 1 The following is a structural diagram of a communication network applicable to an embodiment of the present application. The communication network may be a V2X network, or a part of a V2X network. The V2X network includes communication modes such as V2V (Vehicle to Vehicle), V2P (Vehicle to Pedestrian), V2I (Vehicle to Infrastructure), and V2N (Vehicle to Network). Among them, one end of the V2P communication may be a P-UE (Person-User Equipment), and the other end may be a V-UE (Vehicle-User Equipment), for example Figure 1 The communication network may further include a network side device 100. Both the P-UE 200 and the V-UE 300 may be connected to the network side device 100 via a wireless network.

[0104] The network-side device 100 is a device that provides wireless communication functions for terminal devices, including but not limited to: gNB, RNC (radio network controller), NB (node ​​B), BSC (base station controller), BTS (base transceiver station), HNB (for example, home evolved node B, or home node B), BBU (Base Band Unit), TRP (transmitting and receiving point), TP (transmitting point), mobile switching center, etc. in 5G. The network-side device 100 may also be a device that provides wireless communication functions for terminal devices in other communication systems that may appear in the future.

[0105] The P-UE 200 can be a device with wireless communication capabilities, such as a mobile phone, a tablet, a computer with wireless transceiver capabilities, a VR (virtual reality) terminal, an AR (augmented reality) terminal, or a wireless terminal used in industrial control. The V-UE 300 can be a vehicle-mounted terminal used in self-driving vehicles. Both the P-UE 200 and V-UE 300 can provide voice and / or data connectivity to users and have wireless connectivity, such as by connecting to a wireless modem. The P-UE 200 and V-UE 300 can communicate with one or more core networks via the network-side device 100.

[0106] P-UE200 and V-UE300 have SL (Sidelink, direct link) perception capabilities. Since P-UE200 does not need to receive the data sent by V-UE300, P-UE200 only sends data, that is, it only sends but does not receive. Under this premise, considering the power consumption problem caused by P-UE200 continuously monitoring the channel, P-UE200 can use partial sensing to monitor the channel. When performing partial perception, P-UE200 only receives SCI (Sidelink Control Information, direct link control information) sent by other UE (UserEquipment, terminal equipment), such as V-UE300, at certain non-continuous time domain resource locations, so as to obtain the resource occupancy of other UEs.

[0107] In NR V2X technology, to avoid collisions with aperiodic reserved resources, CPS sensing is added to the PBPS method for resource sensing. While monitoring the reservation status of periodic reserved resources, collisions with aperiodic reserved resources can also be avoided, reducing the probability of collisions with both periodic and aperiodic reserved resources. However, using both PBPS and CPS for resource sensing in all situations increases UE power consumption.

[0108] Based on this, the present application proposes a resource perception method, which can determine the resource perception method for the current business according to the configuration information of the current business. The resource perception method can be to use periodic partial perception PBPS for resource perception; or, the resource perception method can be to use PBPS and continuous partial perception CPS for resource perception, and perform resource perception during the resource reservation process according to the determined resource perception method.

[0109] Through the above method, the UE can continue to use CPS for resource sensing only when PBPS cannot effectively avoid resource collisions, thereby reducing the probability of collisions with non-periodic reserved resources. When PBPS can avoid resource collisions, CPS is no longer used for resource sensing. Therefore, the UE's power consumption can be reduced while ensuring resource transmission reliability.

[0110] Figure 2 The flowchart of a resource perception method provided by an embodiment of the present application is shown. The method is executed by a terminal device, and the following description is given by taking the terminal device executing the resource perception method as an example. Figure 2 As shown, the method may include the following steps:

[0111] Step S201: Determine a resource perception mode for the current service based on configuration information of the current service.

[0112] The configuration information of the current service may include at least one of the following: the PBPS perception duration of the current service, the configuration information of the reassessment and / or preemption check of the current service, and the packet delay budget (PDB) configuration information of the current service. The resource perception method may include using PBPS for resource perception; or using PBPS and CPS for resource perception. The current service may be any periodic or aperiodic transmission transport block (TB).

[0113] Step S202: Perform resource sensing during the resource reservation process according to the determined resource sensing method.

[0114] If the current service configuration information determines that the resource sensing method uses PBPS for resource sensing, the UE uses only PBPS for resource sensing. If the current service configuration information determines that the resource sensing method uses PBPS and CPS for resource sensing, the UE uses both PBPS and CPS for resource sensing. Based on the resource sensing results, the UE may exclude resources already occupied by other terminal devices from the candidate resource set and select the target resource for information transmission from the remaining candidate resources to avoid resource collisions.

[0115] Through the method provided in the embodiments of the present application, the UE can continue to use CPS for resource sensing only when PBPS for resource sensing cannot effectively avoid resource collisions, thereby reducing the probability of collisions with non-periodic reserved resources. When PBPS for resource sensing can avoid resource collisions, CPS for resource sensing is no longer used. Therefore, the UE's power consumption can be reduced while ensuring resource transmission reliability.

[0116] The resource perception method provided in the embodiments of the present application is described in detail below through several specific implementation methods.

[0117] An optional implementation method is: comparing the perceived duration of the PBPS of the current service with a set duration threshold, and determining the resource perception mode according to the comparison result.

[0118] Specifically, when the UE reserves resources for the current service, the network side device can send relevant configurations of the resource pool to the UE. The relevant configurations may include allowing the UE to perceive resources through both PBPS and CPS, as well as the perception parameters and set duration thresholds in PBPS.

[0119] The configuration information of the current service includes the PBPS perception duration of the current service. After receiving the relevant configuration of the resource pool, the UE uses PBPS for resource perception. The UE can determine the perception duration of resource perception using PBPS based on the perception parameters in the PBPS, and compare the perception duration with the set duration threshold included in the resource pool configuration. Based on the comparison result, it determines whether to use CPS for resource perception.

[0120] The above-mentioned perception duration may be the continuous perception duration of the PBPS of the current service, or the effective perception duration of the PBPS of the current service.

[0121] The continuous perception duration is the duration from the start of the first PBPS perception opportunity to the end of the PBPS perception. The PBPS perception end time can be the end of the last PBPS perception opportunity before the resource selection trigger time, or the end of the last PBPS perception opportunity before the first time slot of the candidate resource set. The effective perception duration is the sum of all PBPS perception opportunity durations.

[0122] For example, Figure 3 As shown, in Figure 3 In the example, n-T0 is the start time of the resource perception window, n is the resource selection trigger time, which can also be called the service arrival time, T0 is the duration from the start time of the resource perception window to the resource selection trigger time n, m is the first perception time of PBPS, s is the last perception time of PBPS before the resource selection trigger time n, and nT proc0 is the end time of the resource perception window, T proc0 It is the time to process the perception results after resource perception is completed, T1 is the time to process the service data after the service arrives, n+T1 is the start time of the resource selection window, and n+T2 is the end time of the resource selection window.

[0123] In one embodiment, the PBPS perception end time may be the end time of the last perception opportunity of the PBPS before the resource selection trigger time n; therefore, the continuous perception duration of the PBPS may be the start time of the first perception opportunity of the PBPS (T m The duration between the last perception opportunity of PBPS before the moment n, that is, T m Moment and T s The duration between moments.

[0124] In another embodiment, the PBPS perception end moment may be the end moment of the last perception opportunity of the PBPS before the first time slot of the candidate resource set. Therefore, the continuous perception duration of the PBPS may be the duration between the start moment of the first perception opportunity of the PBPS and the end moment of the last perception opportunity of the PBPS before the first time slot of the candidate resource set.

[0125] If the PBPS perception duration of the current service is the continuous perception duration of the PBPS of the current service, the UE compares the continuous perception duration of the PBPS determined in the above manner with the set first duration threshold. If the continuous perception duration of the PBPS is less than the first duration threshold, the resource perception method is determined to be: using PBPS and CPS for resource perception. For example, Figure 4 As shown, after PBPS, UE can continue to use CPS for resource perception. Figure 4In the example, n-T0 is the start time of the PBPS window, nT proc0 The end time of the PBPS window. In the PBPS window, the UE uses the PBPS method to sense resources. n is the resource selection triggering time, n+T A is the start time of the CPS window, n+T B is the end time of the CPS window, n+T1 is the start time of the resource selection window, n+T2 is the end time of the resource selection window, and Y within the resource selection window represents the candidate resource set. If the PBPS continuous sensing duration is greater than or equal to the first duration threshold, the resource sensing mode is determined to be: using PBPS for resource sensing, that is, no longer using CPS for resource sensing, which can save UE power consumption.

[0126] If the perception duration of the PBPS of the current service is the effective perception duration of the PBPS of the current service, the UE can determine the sum of the durations of the various perception opportunities of the PBPS. For example, assuming that m, ..., k, l, f, h, g, s are the various perception opportunities within the resource perception window, such as Figure 3 As shown, the effective perception duration is the sum of the durations of each perception opportunity m, ..., k, l, f, h, g, s. The effective perception duration of PBPS is compared with the set second duration threshold. If the effective perception duration is less than the second duration threshold, the resource perception method is determined to be resource perception using PBPS and CPS, that is, after the UE performs PBPS, it continues to use CPS for resource perception; if the effective perception duration is greater than or equal to the second duration threshold, the resource perception method is determined to be resource perception using PBPS.

[0127] Another optional implementation is: comparing the ratio of the PBPS perception duration of the current service to the total duration of the resource perception window with a set ratio threshold, and determining the resource perception mode according to the comparison result.

[0128] Specifically, when the UE reserves resources for the current service, the network side device can send relevant configurations of the resource pool to the UE. The relevant configurations may include allowing the UE to perceive resources through both PBPS and CPS, as well as setting a ratio threshold in PBPS.

[0129] The configuration information of the current service includes the PBPS perception duration of the current service. After receiving the relevant configuration of the resource pool, the UE uses PBPS for resource perception; determines the perception duration for resource perception using PBPS, and determines the proportion of the PBPS perception duration of the current service to the total duration of the resource perception window, compares the determined proportion of the PBPS perception duration to the total duration of the resource perception window with the set proportion threshold contained in the resource pool configuration, and determines whether to use CPS for resource perception based on the comparison result.

[0130] The above-mentioned perception duration may be the continuous perception duration of the PBPS of the current service, or the effective perception duration of the PBPS of the current service.

[0131] The duration of the PBPS perception of the current service is described as the duration of the continuous perception of the PBPS of the current service. For example, Figure 3 As shown, in one embodiment, the continuous sensing duration of the PBPS may be the starting time of the first sensing opportunity of the PBPS (T m The duration between the last perception opportunity of PBPS before the moment n, that is, T m Moment and T s The total duration of the resource perception window is n-T0 and nT proc0 duration between moments; a first ratio corresponding to the continuous perception duration of the PBPS and the total duration of the resource perception window can be determined.

[0132] In another embodiment, the continuous perception duration of the PBPS can be the duration between the start time of the first perception opportunity of the PBPS and the end time of the last perception opportunity of the PBPS before the first time slot of the candidate resource set; the total duration of the resource perception window is the time between n-T0 and nT proc0 duration between moments; a first ratio corresponding to the continuous perception duration of the PBPS and the total duration of the resource perception window can be determined based on the determined continuous perception duration of the PBPS.

[0133] The UE compares the first ratio of the continuous perception duration of the PBPS determined in the above manner to the total duration of the resource perception window with the set first ratio threshold; if the first ratio is less than the first ratio threshold, the resource perception method is determined to be: using PBPS and CPS for resource perception, such as Figure 4 As shown, after performing PBPS, the UE continues to use CPS for resource perception; if the first ratio is greater than or equal to the first ratio threshold, the resource perception method is determined to be: using PBPS for resource perception, that is, there is no need to use CPS for resource perception, which can save UE power consumption.

[0134] If the perception duration of the PBPS of the current service is the effective perception duration of the PBPS of the current service, the UE can determine the sum of the durations of each perception opportunity of the PBPS, and the sum is the effective perception duration. According to the effective perception duration and the total duration of the resource perception window, the second proportion of the effective perception duration of the PBPS to the total duration of the resource perception window is determined, and the second proportion is compared with the set second proportion threshold; if the second proportion is less than the second proportion threshold, the resource perception method is determined to be: using PBPS and CPS for resource perception, that is, after the UE performs PBPS, CPS continues to be used for resource perception; if the second proportion is greater than or equal to the second proportion threshold, the resource perception method is determined to be using PBPS for resource perception, that is, there is no need to use CPS for resource perception, which can save the power consumption of the UE.

[0135] Another optional implementation is to determine the resource perception mode according to the configuration information of the re-evaluation and / or preemption check of the current service.

[0136] Specifically, when the UE reserves resources for the current service, the network side device can send relevant configurations of the resource pool to the UE. The relevant configurations may include configuration information allowing the UE to perceive resources through PBPS and CPS, as well as re-evaluation and / or preemption checks.

[0137] The configuration information of the current service is the configuration information of the re-evaluation and / or preemption check of the current service. After receiving the relevant configuration of the resource pool, the UE configures the corresponding re-evaluation enable flag according to the received configuration information of the re-evaluation and / or preemption check. For example, if the configuration information instructs the UE to perform re-evaluation and / or preemption check, the UE can configure the re-evaluation enable flag to 1 according to the configuration information; if the configuration information instructs the UE not to perform re-evaluation and / or preemption check, the UE can configure the re-evaluation enable flag to 0 according to the configuration information.

[0138] After configuring the re-evaluation enable flag in the above manner, the UE can determine the resource sensing mode according to the information of the enable flag. If the configuration information of the re-evaluation and / or preemption check of the current service indicates that the UE does not re-evaluate and / or preempt the resources of the current service, the resource sensing mode is determined as follows: using PBPS and CPS for resource sensing, such as Figure 4 As shown, after performing PBPS, the UE continues to use CPS for resource sensing. If the configuration information of the reassessment and / or preemption check of the current service instructs the UE to reassess and / or preempt the resources of the current service, the resource sensing mode is determined to be: using PBPS for resource sensing, that is, no longer using CPS for resource sensing, which can save UE power consumption.

[0139] Another optional implementation method is: determining the resource perception mode according to the PDB configuration information of the current business.

[0140] When a UE reserves resources for a current service, the network device may send the UE relevant configuration of the resource pool. The relevant configuration may include allowing the UE to sense resources through both PBPS and CPS, as well as a PDB threshold related to the use of CPS. The PDB threshold is less than or equal to the minimum window length value of the CPS perception window, that is, the PDB threshold can be the minimum window length value configured for the CPS perception window; it can also be any value less than the minimum window length value configured for the CPS perception window.

[0141] For example, Figure 3 As shown in Figure 1, time n is called the service arrival time. When a service arrives, the service data carries the PDB configuration information for the current service. After obtaining the PDB configuration information for the current service, the UE compares the PDB configuration information with the PDB threshold contained in the resource pool configuration and determines whether to perform CPS resource sensing based on the comparison result.

[0142] If the PDB configuration information is less than the set PDB threshold, the resource sensing method is determined to be: PBPS for resource sensing, that is, there is no need to use CPS for resource sensing. If the PDB configuration information is greater than or equal to the set PDB threshold, the resource sensing method is determined to be: PBPS and CPS for resource sensing, that is, the UE continues to use CPS for resource sensing after performing PBPS.

[0143] Another optional implementation is to determine the resource perception method based on at least two of the PBPS perception duration of the current service, the configuration information of the re-evaluation and / or preemption check of the current service, and the PDB configuration information of the current service.

[0144] The configuration information of the current service includes at least two of the following: the PBPS perception duration of the current service, the configuration information for reassessment and / or preemption check of the current service, and the PDB configuration information of the current service. If the UE determines that any one of the configuration information satisfies the conditions for not using CPS for resource perception, it determines the resource perception mode as: using PBPS for resource perception; otherwise, it determines the resource perception mode as: using PBPS and CPS for resource perception.

[0145] Exemplarily, when the UE reserves resources for the current service, the network-side device may send relevant configurations of the resource pool to the UE. The relevant configurations may include allowing the UE to perceive resources through both PBPS and CPS, a set duration threshold in PBPS, a set ratio threshold in PBPS, configuration information for re-evaluation and / or preemption check, and a PDB threshold related to the use of CPS.

[0146] In one embodiment, if the configuration information of the current service includes three types: the PBPS perception duration of the current service, the configuration information of the re-evaluation and / or preemption check of the current service, and the PDB configuration information of the current service, when the UE determines that any one of the configuration information satisfies the condition that the CPS is not required for resource perception, the resource perception mode is determined to be: using the PBPS for resource perception, i.e., no longer needing to use the CPS for resource perception, thereby saving the UE's power consumption.

[0147] The conditions for not using CPS for resource perception include: the perception duration of PBPS is greater than or equal to the set duration threshold, or the proportion of the perception duration of PBPS to the total duration of the resource perception window is greater than or equal to the set proportion threshold, or the configuration information of the re-evaluation and / or preemption check instructs the UE to re-evaluate and / or preempt the current service, or the PDB configuration information is less than the set PDB threshold.

[0148] Specifically, after receiving the relevant configuration of the resource pool, the UE uses PBPS to sense the resources and performs the following operations:

[0149] Determine the duration of resource perception using PBPS, compare the duration with a set duration threshold, and if the PBPS perception duration is greater than or equal to the set duration threshold, determine whether PBPS is used for resource perception. Alternatively, determine the ratio of the PBPS perception duration of the current service to the total duration of the resource perception window, compare the ratio with a set ratio threshold, and if the ratio is greater than or equal to the set ratio threshold, determine whether PBPS is used for resource perception.

[0150] Otherwise, obtain the configuration information of re-evaluation and / or preemption check. If the configuration information of re-evaluation and / or preemption check indicates that the UE re-evaluates and / or preempts the current service, determine to use PBPS for resource perception.

[0151] If the configuration information of the re-evaluation and / or preemption check indicates that the UE does not re-evaluate and / or preempt the current service, then at the time of service arrival, the PDB configuration information of the service arrival is obtained, and the PDB configuration information is compared with the set PDB threshold. If the PDB configuration information is less than the set PDB threshold, it is determined to use PBPS for resource perception; if the PDB configuration information is greater than or equal to the set PDB threshold, it is determined to use PBPS and CPS for resource perception.

[0152] The resource sensing method provided in the embodiments of the present application allows the UE to continue using CPS for resource sensing only when PBPS cannot effectively avoid resource collisions, thereby reducing the probability of collisions with non-periodic reserved resources. When PBPS can avoid resource collisions, CPS is no longer used for resource sensing. This can reduce UE power consumption while ensuring resource transmission reliability.
