Description

Technical Field

[0001] The present invention relates to the field of wireless technology, and in particular to a sensing method, a configuration method, a device, a terminal and a base station. Background Art

[0002] New Radio (NR)-Vehicle-to-Everything (V2X) supports two resource allocation modes: Mode 1 resource allocation mode and Mode 2 resource allocation mode, where Mode 1 is a resource allocation mode controlled by the base station and Mode 2 is a terminal autonomous resource allocation mode. The resource selection mode of Mode 2 is "listen before send", which determines the resources to be selected in the resource selection window based on the perception of the resources in the sensing window.

[0003] Among them, the mode 2 resource selection mode includes a partial sensing method, in which NR-V2X supports a maximum of 16 reservation periods for each resource pool, and the reservation period value supports 0, 1 to 99, 100, 200, 300, 400, 500, 600, 700, 800, 900 and 1000ms.

[0004] However, in the partial perception mechanism, LTE-V2X can work better when the resource reservation period is greater than or equal to 100ms; while the NR-V2X resource reservation period supports values ​​from 0, 1 to 99, 100, 200, 300, 400, 500, 600, 700, 800, 900 and 1000ms, and the resource reservation period takes any value from 1 to 99. Directly applying the partial perception mechanism of LTE-V2X will cause many time slots to be unable to be perceived, resulting in resource collisions and reliability cannot be guaranteed.

[0110] In order to make the technical problems, technical solutions and advantages to be solved by the present invention more clear, a detailed description will be given below with reference to the accompanying drawings and specific embodiments.

[0111] In order to clearly illustrate the perception method described in the embodiment of the present invention, the resource selection mode of mode 2 and some perception methods in the resource selection mode of mode 2 are first described below.

[0112] Among them, in the resource selection mode of mode 2, based on the perception of the resources in the perception window, the resources to be selected in the resource selection window are determined, combined with Figure 1 As shown, its basic working process includes:

[0113] Determine the resource selection window and perception window: where time n is the time at which the UE process for determining the resource subset to be reported to the upper layer is triggered, then the resource selection window is determined to be [n+T1, n+T2], and the perception window is Time slots within the range; T0 and Defined in 3GPP standards.

[0114] Perception process: demodulate the physical sidelink control channel (PSCCH) sent by other terminals in the perception window and collect the reference signal receiving power (RSRP) information;

[0115] Exclude resource process:

[0116] Since V2X is half-duplex, the terminal cannot monitor in its own transmission time slot, so it can only assume that one or more resources reserved by other UEs in the time slot with all possible periods configured by the system overlap with the candidate resources in the resource selection window or the periodic reserved resources after the candidate resources, and exclude the resources;

[0117] When the occupied resources and one or more subsequent reserved resources indicated by the decoded SCI overlap with the candidate resources in the resource selection window or one or more reserved resources after the candidate resources, and the RSRP is higher than a certain threshold, the resources are excluded;

[0118] If the remaining resources are less than the preset percentage of the entire set, the RSRP threshold is increased by a certain value, such as 3 dB, and the resource exclusion step is repeated;

[0119] The available resources are reported to the Media Access Control (MAC) layer, and the MAC layer performs random selection.

[0120] It should be noted that the perception window is defined as The time slots in the range of n are triggered for determining the UE process of the resource subset that needs to be reported to the upper layer, T0 and It is a parameter defined according to the standard protocol; wherein, the time slot can be a time slot or a logical time slot. In the partial perception mode, compared with the resource selection mode of mode 2, in the process of determining the resource selection window and the perception window, the resource selection window is reduced to part (such as Y) of the time slots in the resource selection window [n+T1, n+T2] in mode 2, where Y is selected autonomously by the terminal. The perception window is a subset of the resource perception window in mode 2 and is related to Y time slots. In the partial perception mechanism, when the resource reservation period is greater than or equal to 100ms, it can work better; while the NR-V2X resource reservation period supports values ​​from 0, 1 to 99, 100, 200, 300, 400, 500, 600, 700, 800, 900 and 1000ms. When the resource reservation period takes any value between 1 and 99, many time slots cannot be perceived, resulting in resource collisions and reliability cannot be guaranteed.

[0121] To solve the above technical problems, an embodiment of the present invention provides a perception method. Compared with configuring the step size for determining the resource perception window as a fixed value Pstep, the method of the present invention flexibly determines the step size according to the value in the resource reservation period list configured by the resource pool, and enhances the perception method based on this, so that when the reservation period configured by the resource pool is an arbitrary value, the partial perception mechanism is used to perform resource perception well, so as to avoid resource collisions to the greatest extent and ensure the reliability of data transmission.

[0122] like Figure 3 As shown, the sensing method described in the embodiment of the present invention includes:

[0123] S310, the terminal monitors the time slot; wherein the time slot is determined according to the first step length T or the value T' after the first step length is converted into a logical time slot;

[0124] The first step length satisfies at least one of the following conditions:

[0125] The first step length is less than or equal to any value in the first period list, or less than or equal to the minimum value of the values ​​in the first period list;

[0126] The first step length is a common divisor of the values ​​in the first period list;

[0127] The first cycle list is a resource reservation cycle list in the resource pool configuration, or the first cycle list includes values ​​after the cycle values ​​in the resource reservation cycle list of the resource pool configuration are converted into logical time slots.

[0128] In some perception modes, such as Figure 2 As shown, the sensing window is a subset of the resource sensing window in mode 2. According to the preset value indicated by the first indication, such as 1, in the time slot In the case of Y time slots included in the resource selection window, the terminal needs to sense Time slot, that is, the need to perceive and time slot Resources separated by gap time slots, where gap = k*Pstep.

[0129] Wherein, k indicates that the kth bit indicated by the first indication of the high-level parameter is 1. Pstep is the first step length T, or the value T' after the first step length is converted into a logical time slot.

[0130] like Figure 2 As shown, in one implementation mode, taking the perception window as 1000ms, the resource selection window as 100ms, and Pstep=100ms as an example, according to the parameter indication of the first indication, the terminal selects Y candidate time slots in the resource selection window, and the corresponding candidate perception time slots in the perception window are the time slots with left diagonal shadows and the time slots with right diagonal shadows. Through the first indication of the high-level configuration, it can be known that the final perception time slot is the time slot with left diagonal shadows.

[0131] Using the above-mentioned partial perception mechanism, it is obvious that it can work better when the resource reservation period is greater than or equal to 100ms; while the NR-V2X resource reservation period supports values ​​from 0, 1 to 99, 100, 200, 300, 400, 500, 600, 700, 800, 900 and 1000ms. When the resource reservation period takes any value between 1 and 99, many time slots cannot be perceived, resulting in resource collisions and reliability cannot be guaranteed. In this embodiment of the present invention, Pstep in the partial perception mechanism of LTE-V2X is defined as the first step length T or the value T' after the first step length is converted into a logical time slot, that is, if the time slot is included in the Y time slots of the resource selection window, then the time slots that the terminal needs to perceive need to include That is, when the kth bit indicated by the first indication is a preset value, such as 1 or 0, the distance time slot needs to be sensed. It is part or all of the time slots in gap=k*T time slots.

[0132] In an embodiment of the present invention, the first step length needs to satisfy at least one of the above conditions. The first step length is determined to be less than or equal to the minimum value in the first cycle list, or less than or equal to any value in the first cycle list, or a common divisor of the values ​​in the first cycle list, so as to flexibly determine the step length, and ensure that when the cycle value in the cycle list configured by the resource pool is any value, the partial perception mechanism is used for resource perception to achieve a good resource perception state, thereby avoiding resource collisions to the greatest extent and ensuring the reliability of data transmission.

[0133] For example, assuming that one of the resource pools is configured or pre-configured to support eight values ​​of reservation periods, namely, 20ms, 50ms, 100ms, 200ms, 300ms, 400ms, 500ms and 600ms, in its resource reservation period list. If the first step length T is a common divisor of all reservation periods, then the first step length can be determined to be 10ms, or a divisor of 10ms.

[0134] Optionally, in another implementation, the first step length T may also be less than or equal to the minimum value of any of the above-mentioned reservation periods or all reservation periods, that is, T is less than or equal to 20 ms.

[0135] In another embodiment, the first period list for determining the first step length T includes the period value in the resource reservation period list configured by the resource pool after being converted into the value of the logical time slot. For example, assuming that the resource reservation period list configured by the resource pool includes 8 values ​​of 20ms, 50ms, 100ms, 200ms, 300ms, 400ms, 500ms and 600ms, and the values ​​of these reservation periods after being converted into logical time slots are 40, 100, 200, 400, 600, 800, 1000 and 1200 respectively, then if the first step length T is the common divisor of all reservation periods, then the first step length can be determined to be 20 logical time slots, or a divisor of 20 logical time slots; optionally, the first step length T can also be less than or equal to the minimum value of any of the above logical time slots or all logical time slots, that is, T is a value less than or equal to 40 logical time slots.

[0136] In the embodiment of the present invention, optionally, the first step length T is determined by at least one of terminal implementation, pre-configuration and base station high-layer signaling configuration.

[0137] For example, the first step length T is determined by the terminal, and the first step length T needs to meet at least one of the above conditions; or

[0138] The first step length T is determined by pre-configuration or base station high-layer signaling configuration, and the first step length T needs to meet at least one of the above conditions.

[0139] Optionally, the high-level signaling includes but is not limited to only including system information block (System Information Block, SIB), radio resource control (Radio Resource Control, RRC) and media access control (Media Access Control, MAC) messages, etc.

[0140] In the embodiment of the present invention, combined with Figure 3 In step S310, the terminal monitors the time slot, including:

[0141] When the value of the kth bit number of the first indication is a preset value, the terminal monitors a time slot that is separated from the target resource by S Ts or S T's.

[0142] The time slot that the terminal should monitor is determined according to the first step length T, or the value T' after the first step length is converted into a logical time slot, including:

[0143] In the case where the first step length T is a duration value, when the value of the kth bit number of the first indication is a preset value, it is determined that the terminal should monitor a time slot that is S T' apart from the target resource.

[0144] Another implementation manner, determining the time slot that the terminal should monitor according to the first step length T, or the value T' after the first step length is converted into a logical time slot, includes:

[0145] In the case where the first step length T is a logical time slot, when the value of the kth bit number of the first indication is a preset value, it is determined that the terminal should monitor a time slot that is S times T apart from the target resource.

[0146] In the embodiment of the present invention, the first indication is the candidate sensing resource indication gapCandidateSensing in the partial sensing mechanism, in the time slot In the case of being included in the Y time slots of the resource selection window, the first indication is used to indicate that the terminal needs to perceive Which time slots in the time slot; wherein, optionally, for example, when the kth bit indicated by the first indication is 1 or 0, the terminal needs to perceive Some or all of the time slots.

[0147] In the embodiment of the present invention, S and k are associated with each other.

[0148] In this embodiment of the present invention, the first indication includes M bits, where the value of M is determined by at least one of the following methods:

[0149] The value of M is the ratio L of the perception window size to the first step length T;

[0150] The value of M is the ratio L' of the perception window size to the value T' after the first step length T is converted into a logical time slot;

[0151] The M is equal to the value obtained by dividing the L or L' by the value N;

[0152] Wherein, the value of M and the value of N are both positive integers.

[0153] In the embodiment of the present invention, the number of M bits included in the first indication is determined according to the duration value of the first step length, that is, according to the value before the first step length is converted into a logical time slot.

[0154] In the embodiment of the present invention, optionally, the value N may be determined by at least one of protocol pre-definition, pre-configuration, and base station high-layer signaling configuration.

[0155] For example, if one of the resource pools is configured through configuration or pre-configuration to configure the resource reservation period list of the resource pool, and the supported reservation periods include 8 values: 20ms, 50ms, 100ms, 200ms, 300ms, 400ms, 500ms and 600ms, then through terminal implementation or pre-configuration, when the first step length is determined to be 10ms, if the perception window size, that is, the perception window length, is 1000ms, then when the value of M is the ratio L of the perception window size to the first step length, it can be determined that the first indication requires 100 bits, that is, the value of M is 100 bits; when the value of M is the ratio L divided by the value N, when N=5, it can be determined that the first indication requires 20 bits, that is, the value of M is 20 bits.

[0156] For example, in another implementation, if the perception window size, that is, the perception window length, is 1000ms, including 2000 logical time slots, in the resource reservation period list configured for the resource pool, the reservation period includes 8 values ​​of 20ms, 50ms, 100ms, 200ms300ms, 400ms, 500ms and 600ms, and the values ​​of these reservation periods after conversion to logical time slots are 40, 100, 200, 400, 600, 800, 1000 and 1200 respectively, the first step length is set to 20 logical time slots, the perception window size is 2000 time slots or 2000 logical time slots, and the value of M is the ratio L of the perception window size to the first step length T, it can be determined that the value of M is 100 bits; when the value of M is the value obtained by dividing the ratio L by the value N, when N=5, it can be determined that the first indication requires 20 bits, that is, the value of M is 20 bits. In the sensing method of the embodiment of the present invention, in one implementation, when the value of M is the ratio L of the sensing window size to the first step length, or the ratio L' of the sensing window size to the value T' after the first step length is converted into a logical time slot, and the kth bit indicated by the first indication is a preset value, such as 0 or 1, indicating that the terminal needs to sense If part or all of the time slots are in the time slot, the first indication includes the value of the M bits, each bit corresponding to the case where k takes an integer value, that is, if is included in the Y time slots of the resource selection window, and the kth bit of the first indication is a preset value, then the terminal needs to perceive any time slot of .

[0157] That is, specifically, when the value of M is the ratio L of the perception window size to the first step length, or the ratio L' of the perception window size to the value T' after the first step length is converted into a logical time slot, S is equal to k.

[0158] For example, if one of the resource pools configures the resource reservation period list of the resource pool by configuration or pre-configuration, and the supported reservation periods include 8 values ​​of 20ms, 50ms, 100ms, 200ms, 300ms, 400ms, 500ms and 600ms, then it is determined through the terminal implementation or pre-configuration that the first step length T is 10ms, if the perception window size, that is, the perception window length, is 1000ms, then when the value of M is the ratio L of the perception window size to the first step length, it can be determined that the first indication requires 100 bits, that is, the value of M is 100 bits;

[0159] In this case, the first indication includes the value of the M bits, each bit corresponding to the case where k takes an integer value, so that in the time slot is included in the Y time slots of the resource selection window, and the kth bit of the first indication is a preset value, assuming that the time slot value after the first step length T is converted into a logical time slot is also 10, then the terminal needs to perceive any time slot of .

[0160] In another implementation, if the perception window size, that is, the perception window length, is 1000 ms, including 2000 logical time slots, the values ​​of the reserved period of the resource pool after conversion into logical time slots are 40, 100, 200, 400, 600, 800, 1000 and 1200 respectively, the first step length is set to 20 logical time slots, the perception window size is 2000 time slots or 2000 logical time slots, and the value of M is the ratio L of the perception window size to the first step length T, then the value of M can be determined to be 100 bits; in this case, the value of the M bits included in the first indication, each bit corresponds to the case where k takes an integer value, so that in the time slot is included in the Y time slots of the resource selection window, and the kth bit of the first indication is a preset value, the terminal needs to perceive any time slot of .

[0161] In another embodiment, when M is equal to the value obtained by dividing L or L' by the value N, S includes a value calculated in the following manner, specifically the following two determination methods:

[0162] The first determination method, N×(k-1)+Q1;

[0163] Here, Q1 includes every integer value from 1 to N.

[0164] Or, the second way to determine:

[0165] k+Q2M;

[0166] Here, Q2 includes every integer value from 0 to N-1.

[0167] Specifically, for the first determination method mentioned above:

[0168] Since the total number of bits M included in the first indication is equal to the value obtained by dividing L or L' by the value N, each bit indicated by the first indication corresponds to N time slots in the perception window, that is, each bit corresponds to the case where k takes N integer values. In one implementation, Figure 4 As shown, when the kth bit indicated by the first indication is 1, it means that the terminal needs to perceive any time slot of the M time slots in the kth group of the perception window, that is, it needs to perceive any time slot of .

[0169] That is, when the value of the kth bit number of the first indication is a preset value, the terminal should monitor a time slot that is S times the first step length away from the target resource, where S includes any value calculated based on N×(k-1)+Q1, and Q1 includes every integer value from 1 to N.

[0170] For example, if one of the resource pools is configured or pre-configured in a resource reservation period list of the resource pool, and the supported reservation periods include 8 values ​​of 20ms, 50ms, 100ms, 200ms, 300ms, 400ms, 500ms and 600ms, then through the terminal implementation or pre-configuration, it is determined that when the first step length T is 10ms, if the perception window size, that is, the perception window length, is 1000ms, when the value of M is the ratio L divided by the value N, and N=5, it can be determined that the first indication requires 20 bits, that is, when the value of M is 100 bits, if the time slot is included in the Y time slots of the resource selection window, and the kth bit of the first candidate perception resource indication is 1, then the terminal needs to perceive any time slot of .

[0171] Similarly, when the first step length T is determined by converting the period value in the resource reservation period list in the resource pool configuration into a logical time slot, the method for determining the perception gap is the same as above and no further examples are given here.

[0172] For the second determination method mentioned above:

[0173] Since the total number of bits M included in the first indication is equal to the value obtained by dividing the ratio L by the value N, each bit indicated by the first indication corresponds to N time slots in the perception window, that is, each bit corresponds to the case where k takes N integer values. In one implementation, Figure 5 As shown, when the kth bit indicated by the first indication is 1, it means that the terminal needs to sense the kth time slot in each group of M time slots in the sensing window, that is, it needs to sense any time slot of .

[0174] That is, when the value of the kth bit number of the first indication is a preset value, when determining that the terminal should monitor a time slot that is S times the first step length away from the target resource, S includes each value determined according to k+Q2M; wherein Q2 includes each integer value from 0 to N-1.

[0175] For example, if one of the resource pools is configured or pre-configured in a resource reservation period list of the resource pool, and the supported reservation periods include 8 values ​​of 20ms, 50ms, 100ms, 200ms, 300ms, 400ms, 500ms and 600ms, then through the terminal implementation or pre-configuration, it is determined that when the first step length T is 10ms, if the perception window size, that is, the perception window length, is 1000ms, when the value of M is the ratio L divided by the value N, and N=5, it can be determined that the first indication requires 20 bits, that is, when the value of M is 100 bits, if the time slot is included in the Y time slots of the resource selection window, and the kth bit of the first candidate perception resource indication is 1, then the terminal needs to perceive any time slot of .

[0176] Similarly, when the first step length T is determined by converting the period value in the resource reservation period list in the resource pool configuration into a logical time slot, the method for determining the perception gap is the same as above and no further examples are given here.
