Description

Technical Field

[0001] (Cross - reference to related applications) This application claims the priority of a Chinese patent with the application number No. 202010791656.5, filed in China on August 7, 2020, and all of its contents are incorporated herein by reference.

[0002] This application belongs to the technical field of communications, and specifically relates to a method, apparatus, and terminal for obtaining a detection window.

Background Art

[0003] The Long Term Evolution (LTE) system supports sidelink transmission, that is, direct data transmission between terminals (also referred to as User Equipment, UE) on the physical layer. LTE sidelink communicates based on broadcast and can be used to support basic security communications for vehicle - to - vehicle and vehicle - to - everything (V2X), but it cannot be applied to other more advanced V2X services. The 5G New Radio (NR) system can support more comprehensive service types because it supports more advanced sidelink transmission designs, such as unicast, multicast, etc.

[0004] In LTE, partial detection is designed for power saving and to support communication between pedestrians and vehicles (Pedestrian to Vehicle, P2V). The terminal supports two modes of resource selection methods: random resource selection, and after performing partial detection, selecting resources based on the results of the partial detection and making semi-static resource reservations. Among them, which mode of resource selection method the terminal selects is set by Radio Resource Control (RRC). However, when RRC is set to support resource selection in two modes, which resource selection method to adopt is determined by the terminal.

[0005] In the process of realizing this application, the inventor found that the prior art has at least the following problems. In LTE sidelink, the step size of partial detection in the sidelink resource pool is fixed at 100 ms. From the periodic settings in LTE, the detection window obtained at k * 100 ms can almost detect the resource reservation status of other UEs in the resource pool. However, in NR, the selectable values of the detection period are not regular. If the detection window is obtained with 100 ms as the step size, the resource reservation status of other terminals (for example, terminals with a reservation period of [1:99]) within the selected window cannot be detected, and when the detecting terminal selects resources, there is a possibility that the selected resources will conflict with the resources reserved by other terminals.

These technologies are applicable beyond the NR system. For example, they are also applicable to the 6th Generation (6G) communication system. th Generation, 6G) communication system.

[0018] In the embodiments of the present application, the terminal may also be referred to as a terminal device or a user equipment (UE), and may also be a laptop computer (Laptop Computer), also known as a mobile phone, a tablet personal computer, a notebook computer, a personal digital assistant (Personal Digital Assistant, PDA), a personal digital assistant, a netbook, an ultra-mobile personal computer (ultra-mobile personal computer, UMPC), a mobile Internet device (Mobile Internet Device, MID), a wearable device (Wearable Device) or an in-vehicle device (VUE), a pedestrian terminal (PUE), etc. The wearable device may include a bracelet, earphone, glasses, etc. It is necessary to explain that the specific type of the terminal is not limited in the embodiments of the present application.

[0019] Hereinafter, with reference to the drawings, the method, apparatus and terminal for obtaining a detection window provided in the embodiments of the present application will be described in detail by specific embodiments and their usage scenarios.

[0020] As shown in FIG. 1, an embodiment of the present application is a method for obtaining a detection window applied to a terminal, Step 101 of obtaining a first resource detection window by at least one step size P; Step 102 of obtaining a second resource detection window by a resource selection window; A method for obtaining a detection window including at least one of the above is further provided.

[0021] Here, the first resource detection window may be one or more windows, and the second resource detection window may be one or more windows. Optionally, step 101 specifically is to obtain the first resource detection window by at least one step size P and a resource selection window.

[0022] As a selectable embodiment, when the first condition is satisfied, the second resource detection window is obtained by step 101; otherwise, the first resource detection window is obtained by step 102. The first condition includes that the period set by the terminal is smaller than the first period threshold; that there is one or more non-zero periods smaller than the second period threshold in the period set for the resource pool; that the period set for the resource pool is disabled; that the period set by the terminal is 0 and includes at least one of them.

[0023] When the period set for the resource pool is disabled, other terminals in the resource pool transmit aperiodically. In this way, it is necessary to explain that the second resource detection window may be used for detection in the resource selection window, and this second resource detection window may be a dynamic resource selection window. Or, when the period set by the terminal is 0, that is, when the terminal transmits aperiodically, the second resource detection window may be used for detection in the resource selection window.

[0024] At least one of the first period threshold and the second period threshold is a predefined threshold, a preset threshold, a set threshold, and a threshold related to the period set for the resource pool and is at least one of them.

[0025] Among them, the preset or setting may be a preset or setting by a network, or a preset or setting by a terminal. Alternatively, the first cycle threshold and / or the second cycle threshold are values indicated by a network or a terminal. The setting may specifically be a setting by upper layer signaling, and the network or terminal indication may be an indication by physical layer signaling. For example, it may be set / indicated by RRC signaling, media access control layer control unit (MAC CE) signaling, sidelink control information SCI signaling, PC5-RRC signaling, SCI, feedback information, physical sidelink feedback channel (PSFCH), etc.

[0026] As another selectable embodiment, the method determining the step size P according to a period set in a resource pool; determining the step size P according to a period set by a terminal; determining the step size P according to a period of sidelink discontinuous reception (DRX); determining the step size P according to a predefined or preset or set value; and further includes at least one of them. Among them, the preset or setting may be a preset / setting by a network, or a preset or setting by a terminal. For example, it may be set / indicated by RRC signaling, MAC CE signaling, SCI signaling, PC5-RRC signaling, SCI, feedback information, PSFCH, etc. It is necessary to explain that when the step size P is a preset value or a set value, the preset value or the set value becomes a parameter set for each resource pool. For example, the preset value or the set value may be a subset of the period set for the resource pool.

[0027] The number of the step sizes P is less than or equal to a first value, which is advantageous for reducing the number of terminal detection windows and is advantageous for terminal capabilities. That is, the step size P may be one value or a plurality of values (for example, P1, P2, …, Pm). The first value is a predefined value, a preset value, a set value, a value determined by terminal capabilities, or a value determined by service quality.

[0028] It is necessary to explain that the preset or setting may be a preset / setting by the network or a preset or setting by the terminal. Specifically, the setting is a setting by upper layer signaling. For example, it may be set / instructed by RRC signaling, MAC CE signaling, SCI signaling, PC5-RRC signaling, SCI, feedback information, PSFCH, etc.

[0029] When the first value is a value determined by service quality QoS, it may be set for each QoS. For example, associate the corresponding first value for each QoS level, and when the service transmission corresponds to a certain QoS among them, the corresponding first value can be found according to the setting parameters of the QoS. Similarly, when the first value is a value determined by terminal capabilities, it may be set for each terminal capability. For example, associate the first values corresponding to different terminal capabilities, and when the terminal capability of the current terminal is a certain capability, the corresponding first value can be found according to the capability.

[0030] Optionally, the first value is a value set for a resource pool, or the first value is a value related to the setting parameters of the terminal, or the first value is a value related to the setting of a logical channel, or the first value is a value related to the setting of a logical channel group. For example, the first value may be set based on each resource pool. For example, there is a parameter setting of one or more first values (P budget ) in the IE corresponding to the resource pool.

[0031] As another selectable embodiment, according to the period set in the resource pool, the step of determining the step size P is as follows: Determining the step size P according to the least common multiple of some or all of the periods set in the resource pool; Determining the step size P according to the greatest common divisor of some or all of the periods set in the resource pool; Determining the step size P corresponding to the period set in the resource pool according to a step size value corresponding to a predefined, preset, or set period range; and includes at least one of the above. (Example 1)

[0032] As shown in Table 1, predefined, preset, or set the step size value corresponding to at least one period range, and obtain the step size P according to the period set in the resource pool.

Table 1

[0033] Assume that resource pool 1 (RP1) is set to support periodic reservation, and 12 periodic values are set to be [0, 21, 43, 79, 100, 200, 300, 400, 500, 700, 800, 1000] respectively. As can be seen from the period set in the resource pool and Table 1, the step size P1 corresponding to the set period 21 is 30, the step size P2 corresponding to the period 43 is 50, the step size P3 corresponding to the step size 79 is 70, and the step size P4 corresponding to the periods 100, 200, 300, 400, 500, 700, 800, 1000 is 100. If the terminal supports partial detection in the resource pool, the terminal obtains the position of the detection window using the step size P1 = 30, the step size P2 = 50, the step size P3 = 70, and the step size P4 = 100.

[0034] As another selectable embodiment, when there are M1 (where M1 is a predefined, preset, or set value) periodic values (non-zero periodic values) that satisfy the first rule in the setting period of the resource pool, the step of determining the step size P according to the period set for the resource pool includes at least one of the following steps. The step of determining that the step size P includes 100. 100 can cover the detection range of a period of 100*k and can reduce the number of step sizes P. k is a positive integer. The step of determining that the step size P includes the greatest common divisor of some or all of the periodic values that satisfy the first rule. For example, the greatest common divisor of 100*k1 can be mentioned, where k1 is a positive integer. If k1 is an even number, the step size P is at least 200. The step of determining that the step size P includes the least common multiple of some or all of the periodic values that satisfy the first rule. For example, the least common multiple of 100*k2 can be mentioned, where k2 is a positive integer.

[0035] Here, the preset or setting may be a preset / setting by the network or a preset or setting by the terminal. The setting specifically refers to a setting by upper layer signaling. For example, it may be set / instructed by RRC signaling, MAC CE signaling, SCI signaling, PC5-RRC signaling, SCI, feedback information, PSFCH, etc.

[0036] The periodic values that satisfy the first rule are periodic values corresponding to multiples of 100, and periodic values corresponding to multiples of 10 include at least one of them.

[0037] As another selectable embodiment, when there are M2 (where M2 is a predefined, preset, or set value) periodic values that satisfy the second rule in the setting period of the resource pool, the step of determining the step size P according to the period set for the resource pool includes at least one of the following steps. Determining that the step size P includes the least common multiple of some or all of the periodic values that satisfy the second rule. For example, when 10, 20, 40, and 80 are set, the step size P is 80. Determining that the step size P includes the greatest common divisor of some or all of the periodic values that satisfy the second rule. For example, when 10, 20, 40, and 80 are set, the step size P is 10. Determining that the step size P includes the least common multiple of the quantization values of some or all of the periodic values that satisfy the second rule. For example, when 79 is set as the period, it is quantized to 80, and then the least common multiple process is performed. It is considered that the resource detection window obtained by the step size P based on 80 can cover up to the period of 79 in part. Determining that the step size P includes the greatest common divisor of the quantization values of some or all of the periodic values that satisfy the second rule. For example, when 69 is set as the period, it is quantized to 70, and then the greatest common divisor process is performed. It is considered that the resource detection window obtained by the step size P based on 70 can cover up to the period of 69 in part.

[0038] Here, the preset or setting may be a preset / setting by the network or a preset or setting by the terminal. The setting is specifically a setting by upper layer signaling. For example, it may be set / instructed by RRC signaling, MAC CE signaling, SCI signaling, PC5-RRC signaling, SCI, feedback information, PSFCH, etc.

[0039] The periodic values that satisfy the second rule are A period value smaller than 100, and A period value that is not a multiple of 10 includes at least one of them.

[0040] Optionally, in the above embodiments of the present application, the quantization granularity of the part or all of the periods is a predefined, preset, or set value. The quantization rule of the quantization value of the part or all of the period values includes at least one of rounding up, rounding down, rounding, and a predefined, preset, or set rule.

[0041] For example, if the quantization granularity is 10 ms and quantization is performed by rounding up, the quantization result is ceil(period / 10), where ceil is rounding up.

[0042] In the setting period of the resource pool, when there are both period values that satisfy the first rule and period values that satisfy the second rule, the step size P is determined to include 100 in the step size P, determined to include the greatest common divisor of some or all of the period values that satisfy the first rule in the step size P, determined to include the least common multiple of some or all of the period values that satisfy the first rule in the step size P, determined to include the least common multiple of some or all of the period values that satisfy the second rule in the step size P, determined to include the greatest common divisor of some or all of the period values that satisfy the second rule in the step size P, determined to include the least common multiple of the quantization values of some or all of the period values that satisfy the second rule in the step size P, It is necessary to explain that it includes at least one of determining that the step size P includes the greatest common divisor of the quantization values of some or all of the period values that satisfy the second rule.

[0043] As another selectable embodiment, the value of the step size P is equal to some or all of the non-zero period values in the resource pool. For example, when the value of the step size P is equal to all of the non-zero period values in the resource pool, it corresponds to detecting all the period values set in the resource pool once.

[0044] As another selectable embodiment, in the step of determining the step size P according to the period set by the terminal, the step of determining that the step size P is equal to the period set by the terminal is included.

[0045] Or, in the step of determining the step size P according to the period of sidelink discontinuous reception (DRX), the step of determining that the step size P is equal to the period of sidelink DRX is included.

[0046] As a selectable embodiment, when obtaining a first resource detection window according to at least one step size P, the method further includes at least one of: a step of determining the number of the first resource detection windows, where the number includes the selectable number of the first resource detection windows and the actual number of the first resource detection windows; a step of determining the position of the first resource detection window.

[0049] JPEG0007696995000004.jpg40168

[0050] As a selectable embodiment, the step of determining the position of the first resource detection window is as follows: It includes the step of determining that the position of the first resource detection window is some or all of the positions that satisfy Y - j*P within a predetermined range. Y is a resource in the resource selection window of the terminal, j is a value obtained by a predefined, preset, or set parameter, and P is a step size. For example, the value of j may be indicated by a bitmap. Here, the preset or set may be a preset / set by the network or a preset or set by the terminal. The setting is specifically a setting by upper layer signaling. For example, it may be set / indicated by RRC signaling, MAC CE signaling, SCI signaling, PC5 - RRC signaling, SCI, feedback information, PSFCH, etc.

[0051] As shown in FIG. 2, the predetermined range is Between the start position of the selectable resource detection window and the start position of the resource selection window ([n - T0, n + T1]), Between the start position of the selectable resource detection window after a predetermined time and the start position of the resource selection window ([n - T0 + 100, n + T1]), Between the start position of the selectable resource detection window and the end position of the selectable resource detection window ([n - T0, n - T proc,0 ) Between the start position of the selectable resource detection window after a predetermined time and the end position of the selectable resource detection window ([n - T0 + 100, n - T proc,0 ) Between the start position of the resource detection window and the resource selection trigger time ([n - T0, n]), Between the start position of the resource detection window after a predetermined time and the resource selection trigger time ([n - T0 + 100, n]), Between the selectable start position of the resource detection window and the resource selection trigger time, From a predetermined time after the selectable start position of the resource detection window to the resource selection trigger time, Between the end position of the resource detection window and the resource selection trigger time, From a predetermined time after the end position of the resource detection window to the resource selection trigger time, Between the selectable end position of the resource detection window and the resource selection trigger time, From a predetermined time after the selectable end position of the resource detection window to the resource selection trigger time, Between the time length T0 before the start position of the resource selection window and the start position of the resource selection window ([n + T1 - T0, n + T1]), and Between a predetermined time further after the time length T0 before the start position of the resource selection window and the start position of the resource selection window ([n + T1 - T0 + 100, n + T1]) includes at least one of the following.

[0052] Said some positions are The previous N positions, The next N positions, The previous N positions after n - T0 + 100, and The positions indicated by the bitmap bitmap are at least one of them.

[0053] Here, N is the actual number of the first resource detection windows, which may be a predefined, preset, or set numerical value, or a numerical value determined by the setting information (for example, obtained by the bitmap indication). Here, the preset or setting may be a preset / setting by the network or a preset or setting by the terminal. The setting is specifically a setting by the upper layer signaling. For example, it may be set / instructed by RRC signaling, MAC CE signaling, SCI signaling, PC5 - RRC signaling, SCI, feedback information, PSFCH, etc.

[0054] Continuing with the above example, in the embodiments of the present application, the method performing resource exclusion with a first period or a first step size as a period based on at least one of the detection results in the first resource detection window and the detection results in the second resource detection window further includes wherein the first period is the period carried in the sidelink control information received within the resource detection window corresponding to the terminal, and the first step size is the step size corresponding to the period carried in the sidelink control information received within the resource detection window corresponding to the terminal.

[0055] The value of the number of resources to be excluded is Q, and Q is Q being equal to 1, and Q being equal to ceil(step size P / period T), where ceil is the ceiling operation and the period T is not zero, and Q being equal to floor(step size P / period T), where floor is the floor operation and the period T is not zero, that is, only the resources within one step size are excluded, and Q being equal to round(step size P / period T), where round is the rounding operation and the period T is not zero, and becomes one of the above, where the step size P is the detection step size corresponding to the period T, and the step size P may be the corresponding minimum detection step size / maximum detection step size / average detection step size in the resource pool.

[0056] It should be noted that the above Q resources to be excluded may be continuous resources or non - continuous resources, and are not specifically limited here.

[0057] The start time of resource exclusion is the time when the sidelink control information is received, and the start time of the resource selection window of the terminal is included.

[0058] To sum up, in the embodiments of the present application, at least one step size P is used to obtain the first resource detection window, and / or the second resource detection window is obtained by the resource selection window, so as to achieve the purpose of balancing power consumption and detection performance, reduce the position of the time domain resource that the terminal needs to detect, and achieve the purpose of power saving.

[0059] To more clearly describe the method for obtaining the detection window provided in the embodiments of the present application, the following will be further described by several examples. (Example 2)

[0060] In the period set in the resource pool, when there is a period value of 100*k, it is predefined that one step size value P = 100. When there is a period value belonging to [1:99], the least common multiple is taken by the quantization value of the period value to obtain another step size value.

[0061] It is assumed that resource pool 1 (RP1) is set to support periodic reservation, and 12 period values of [0, 20, 40, 80, 100, 200, 300, 400, 500, 700, 800, 1000] are set. In the setting of the resource pool, since there are settings with periods of 100, 200, 300, 400, 500, 700, 800, 1000, 100 is taken as one value of the step size P. There are settings with periods of 20, 40, 80, and the least common multiple corresponding to the periods is 80, so 80 is taken as another value of the step size P.

[0062] If partial detection is supported in the resource pool, when the terminal performs partial detection in the resource pool, it uses step size P1 = 80 and step size P2 = 100 to obtain the position of the resource detection window. (Example 3)

[0063] It is predefined that the terminal obtains the detection step size according to the quantization result of the set period in the resource pool. It is predefined that the quantization granularity is 10 ms, and the quantization value is obtained using rounding as the quantization method. When there is a period value of 100*k, it is predefined that one step size value P = 100. When there is a period value belonging to [1:99], the least common multiple is taken according to the quantization value of the period value, and another step size value is used.

[0064] It is assumed that resource pool 1 (RP1) is set to support period reservation, and 12 period values of [0, 21, 43, 79, 100, 200, 300, 400, 500, 700, 800, 1000] are set. In the setting of the resource pool, since there are settings with periods of 100, 200, 300, 400, 500, 700, 800, 1000, 100 is taken as one value of the step size P. Since there are settings with periods of 21, 43, 79, it is determined that the quantization values are 20, 40, 80 according to the predefined quantization rules. Since the least common multiple corresponding to the period is 80, 80 is taken as another value of the step size P.

[0065] If the terminal supports partial detection in the resource pool, the terminal obtains the position of the resource detection window using step size P1 = 80 and step size P2 = 100. (Example 4)

[0066] When there is a period value smaller than the period threshold set by the upper layer among the non-zero period values set in the resource pool, it is predefined that in the resource pool, the terminal detects the resource using the second resource detection window. Otherwise, the terminal obtains the step size P according to the period value set in the resource pool, determines the resource detection window according to the step size P, and performs resource detection.

[0067] It is assumed that resource pool 1 (RP1) is set to support periodic reservation and 12 periodic values [0, 20, 40, 80, 100, 200, 300, 400, 500, 700, 800, 1000] are set. The upper layer setting period threshold Tthreshold = 30.

[0068] In the resource pool, since the non - zero periodic value 20 < the periodic threshold 30, in the resource pool, the terminal detects using a dynamic resource detection window.

[0069] In the method for obtaining a detection window provided in the embodiments of the present application, it is necessary to explain that the execution entity may be an acquisition device for the detection window or a control module for executing and loading the method for obtaining the detection window in the acquisition device for the detection window. In the embodiments of the present application, taking the execution of the method for obtaining the detection window by the acquisition device for the detection window as an example, the acquisition device for the detection window provided in the embodiments of the present application is described.

[0070] As shown in FIG. 3, the embodiment of the present application is an acquisition device for a detection window applied to a terminal, a first acquisition module 301 used to obtain a first resource detection window by at least one step size P, a second acquisition module 302 used to obtain a second resource detection window by a resource selection window and further provides an acquisition device 300 for a detection window including at least one of them.

[0071] As an alternative embodiment, the device a first determination module used to determine the step size P according to the period set in the resource pool, a second determination module used to determine the step size P according to the period set by the terminal, A third determination module used to determine the step size P according to the period of sidelink discontinuous reception DRX; A fourth determination module used to determine the step size P by pre - definition, pre - setting or setting; It further includes at least one of the above.
