The method determines that a time slot in a sidelink resource pool supports K candidate start symbols; it configures the maximum number of sub-channels in the sidelink resource pool to not exceed floor(N / K), where N and K are both positive integers. By configuring the maximum number of sub-channels or the maximum number of RB sets in the sidelink resource pool using the method proposed in this disclosure, the number of sub-channels in the sidelink resource pool is reduced, thereby reducing the number of blind detection PSCCHs by the terminal equipment and reducing the power consumption of the receiving terminal equipment.

Description

Technical Field

[0001] This disclosure relates to the field of communication technology, and in particular to a method, apparatus and computer-readable storage medium for configuring a resource pool. Background Technology

[0002] In communication systems, with the continuous development of wireless communication, the requirements for communication capabilities are becoming increasingly stringent. In the unlicensed frequency band of the sidelink (SL), the Physical Sidelink Control Channel (PSCCH) is transmitted in one subchannel, located in the lowest subchannel of the lowest resource block (RB) set of the corresponding Physical Sidelink Shared Channel (PSSCH). The receiving terminal device determines the frequency domain position of the PSCCH by blindly detecting all subchannels in the entire resource pool at the position of Automatic Gain Control (AGC) within one slot. In the resource pool configuration of Release 16 (R16) or Release 17 (R17), a single resource pool can contain a maximum of 27 subchannels.

[0003] In the unlicensed band of the side link, it can support two candidate starting symbols (i.e., the positions of two AGCs) in one time slot. The transmitting terminal device may access the channel and start transmitting data at the position of the second candidate starting symbol. This means that the receiving terminal device needs to perform blind detection of PSCCH one by one on the sub-channels in the resource pool at the positions of the two candidate starting symbols. This will greatly increase the number of blind detections and the blind detection complexity of the receiving terminal device. It may also exceed the maximum number of blind detections supported by the receiving terminal device, resulting in high power consumption of the receiving terminal device. Summary of the Invention

[0004] The present disclosure discloses a resource pool configuration method, apparatus, and computer-readable storage medium, which can reduce the number of sub-channels in the sidelink resource pool by configuring the maximum number of sub-channels in the sidelink resource pool to not exceed floor(N / K) or the number of RB sets to not exceed floor(N / (M*K)), thereby reducing the number of blind detection PSCCHs by the receiving terminal equipment and thus reducing the power consumption of the receiving terminal equipment.

[0005] This disclosure provides a resource pool configuration method in one embodiment, applied to an unlicensed frequency band on a sidelink. The method is executed by a network device and includes:

[0019] Another aspect of this disclosure provides a computer-readable storage medium for storing instructions that, when executed, cause the method described in one aspect of the disclosure to be implemented.

[0020] In summary, in the embodiments of this disclosure, it is determined that K candidate start symbols are supported in a time slot of the side-link resource pool; the maximum number of sub-channels contained in the side-link resource pool is configured not to exceed floor(N / K), where N and K are both positive integers. In the embodiments of this disclosure, a resource pool configuration mechanism can be provided, which can configure the maximum number of sub-channels or the maximum number of RB sets contained in the side-link resource pool, thereby reducing the number of sub-channels in the resource pool, thus reducing the blind detection complexity of the receiving terminal equipment, reducing the situation where the number of blind detections exceeds the maximum number of blind detections of the receiving terminal equipment, thus preventing the receiving terminal equipment from receiving data, and reducing the power consumption of the receiving terminal equipment. This disclosure provides a processing method for a "resource pool configuration" scenario, which reduces the number of sub-channels in the side-link resource pool by configuring the maximum number of sub-channels or the maximum number of RB sets contained in the side-link resource pool, thereby reducing the number of blind detections of PSCCH by the receiving terminal equipment and reducing the power consumption of the receiving terminal equipment.

[0036] The network elements or network functions involved in the embodiments of this disclosure can be implemented by independent hardware devices or by software in hardware devices. This disclosure does not limit this.

[0037] The following is a detailed description of a resource pool configuration method, apparatus, and computer-readable storage medium provided in the embodiments of this disclosure, with reference to the accompanying drawings.

[0038] Figure 1 This is a flowchart illustrating a resource pool configuration method provided in an embodiment of this disclosure. The method is executed by a network device, such as... Figure 1 As shown, the method may include the following steps:

[0039] Step 101: Determine if a time slot in the sidelink resource pool supports K candidate start symbols;

[0040] Step 102: Configure the maximum number of sub-channels in the side-link resource pool to not exceed floor(N / K), where N and K are both positive integers.

[0041] In one embodiment of this disclosure, the method can be applied to unlicensed frequency bands of side links.

[0042] In one embodiment of this disclosure, floor is used to indicate rounding down to the nearest integer. For example, floor(N / K) can indicate rounding down to the nearest integer with respect to N / K, such as floor(N / K) being the largest integer not greater than N / K.

[0043] Furthermore, in one embodiment of this disclosure, the time slot supports a candidate start symbol, floor(N) equal to N.

[0044] For example, in one embodiment of this disclosure, it is determined that a candidate start symbol is supported in a time slot of the sidelink resource pool, and the maximum number of subchannels contained in the sidelink resource pool is configured not to exceed floor(N), where floor(N) equals N.

[0045] For example, in one embodiment of this disclosure, one candidate start symbol is supported in one time slot, and the maximum number of sub-channels contained in the configuration side link resource pool can be equal to N.

[0046] For example, in one embodiment of this disclosure, one candidate start symbol is supported in one time slot, and the maximum number of sub-channels contained in the configuration side link resource pool may be less than N.

[0047] Furthermore, in one embodiment of this disclosure, the time slot supports two candidate start symbols, and the maximum number of sub-channels does not exceed floor(N / 2).

[0048] For example, in one embodiment of this disclosure, it is determined that two candidate start symbols are supported in one time slot of the side link resource pool, and the maximum number of sub-channels contained in the side link resource pool is configured not to exceed floor(N / 2).

[0049] Furthermore, in one embodiment of this disclosure, when a candidate start symbol is supported in a time slot, i.e., when K is 1, the maximum number of sub-channels contained in the sidelink resource pool can be configured to be equal to N.

[0050] For example, in one embodiment of this disclosure, N is the maximum number of blind detection physical side link control channels (PSCCHs) supported by the terminal device in a time slot.

[0051] For example, in one embodiment of this disclosure, N is the maximum number of times the terminal device supports blind detection physical downlink control channel (PDCCH) in a time slot.

[0052] For example, in one embodiment of this disclosure, the maximum number of blind PDCCH detections supported by the terminal device in one timeslot is 44, 36, 22, and 20 for 15kHz, 30kHz, 60kHz, and 120kHz, respectively. The value of N represents the maximum number of blind PDCCH detections supported by the reuse terminal device in one timeslot, where different subcarrier spacings correspond to different N values.

[0053] Furthermore, in one embodiment of this disclosure, for a subcarrier spacing of 15 kHz, the value of N can be, for example, 44; for a subcarrier spacing of 30 kHz, the value of N can be, for example, 36; for a subcarrier spacing of 60 kHz, the value of N can be, for example, 22; and for a subcarrier spacing of 120 kHz, the value of N can be, for example, 20.

[0054] For example, in one embodiment of this disclosure, the method further includes:

[0055] N and K are determined based on the subcarrier spacing.

[0056] In one embodiment of this disclosure, the value of K can be, for example, 1, or the value of K can also be 2.

[0057] For example, in one embodiment of this disclosure, for a 15kHz subcarrier spacing, N can be 44, K can be 1, and the maximum number of subchannels in the configuration-side link resource pool does not exceed 44; for a 30kHz subcarrier spacing, N can be 36, K can be 1, and the maximum number of subchannels in the configuration-side link resource pool does not exceed 36; for a 60kHz subcarrier spacing, N can be 22, K can be 1, and the maximum number of subchannels in the configuration-side link resource pool does not exceed 22; for a 120kHz subcarrier spacing, N can be 20, K can be 1, and the maximum number of subchannels in the configuration-side link resource pool does not exceed 20.

[0058] For example, in one embodiment of this disclosure, for a 15kHz subcarrier spacing, N can be 44, K can be 2, and the maximum number of subchannels in the configuration-side link resource pool does not exceed 44 / 2 = 22; for a 30kHz subcarrier spacing, N can be 36, K can be 2, and the maximum number of subchannels in the configuration-side link resource pool does not exceed 36 / 2 = 18; for a 60kHz subcarrier spacing, N can be 22, K can be 2, and the maximum number of subchannels in the configuration-side link resource pool does not exceed 22 / 2 = 11; for a 120kHz subcarrier spacing, N can be 20, K can be 2, and the maximum number of subchannels in the configuration-side link resource pool does not exceed 20 / 2 = 10.

[0059] In summary, in the embodiments of this disclosure, it is determined that K candidate start symbols are supported in one time slot of the side-link resource pool; the maximum number of sub-channels contained in the side-link resource pool is configured not to exceed floor(N / K), where N and K are both positive integers. In the embodiments of this disclosure, a resource pool configuration mechanism can be provided, which can configure the maximum number of sub-channels contained in the side-link resource pool, thereby reducing the number of sub-channels in the resource pool, thus reducing the blind detection complexity of the receiving terminal equipment, reducing the situation where the number of blind detections exceeds the maximum number of blind detections of the receiving terminal equipment, resulting in the receiving terminal equipment being unable to receive data, and reducing the power consumption of the receiving terminal equipment. This disclosure provides a processing method for the "resource pool configuration" scenario, which, by configuring the maximum number of sub-channels contained in the side-link resource pool not to exceed floor(N / K), can reduce the number of sub-channels in the side-link resource pool, reduce the number of blind detections of PSCCH by the receiving terminal equipment, and reduce the power consumption of the receiving terminal equipment.

[0060] Figure 2 This is a flowchart illustrating a resource pool configuration method provided in an embodiment of this disclosure. The method is executed by a network device, such as... Figure 2 As shown, the method may include the following steps:

[0061] Step 201: Determine a candidate start symbol that is supported in a time slot within the sidelink resource pool;

[0062] Step 202: Configure the maximum number of sub-channels in the side-link resource pool to not exceed floor(N), where N and K are both positive integers, and floor(N) equals N.

[0063] In one embodiment of this disclosure, the description of steps 201-202 can be found in the above-described embodiments, and this disclosure does not limit the scope of the embodiments. The optional examples in this disclosure can be arbitrarily combined, and without contradiction, this disclosure can be combined with steps from other embodiments and optional examples from other embodiments.

[0064] In one embodiment of this disclosure, the value of K can be, for example, 1. For instance, the number of candidate start symbols supported in a time slot can be 1.

[0065] Furthermore, in one embodiment of this disclosure, the time slot supports a candidate start symbol, floor(N) equal to N.

[0066] For example, in one embodiment of this disclosure, one candidate start symbol is supported in one time slot, and the maximum number of sub-channels contained in the configuration side link resource pool can be equal to N.

[0067] For example, in one embodiment of this disclosure, one candidate start symbol is supported in one time slot, and the maximum number of sub-channels contained in the configuration side link resource pool may be less than N.

[0068] For example, in one embodiment of this disclosure, for a 15kHz subcarrier spacing, N can be 44, K can be 1, and the maximum number of subchannels in the configuration-side link resource pool does not exceed 44; for a 30kHz subcarrier spacing, N can be 36, K can be 1, and the maximum number of subchannels in the configuration-side link resource pool does not exceed 36; for a 60kHz subcarrier spacing, N can be 22, K can be 1, and the maximum number of subchannels in the configuration-side link resource pool does not exceed 22; for a 120kHz subcarrier spacing, N can be 20, K can be 1, and the maximum number of subchannels in the configuration-side link resource pool does not exceed 20.

[0069] In summary, in the embodiments of this disclosure, it is determined that one candidate start symbol is supported in one time slot of the side-link resource pool; step 202, configure the maximum number of sub-channels contained in the side-link resource pool to not exceed floor(N), where N and K are both positive integers, and floor(N) equals N. In the embodiments of this disclosure, a resource pool configuration mechanism can be provided, which can configure the maximum number of sub-channels contained in the side-link resource pool, thereby reducing the number of sub-channels in the resource pool, thereby reducing the blind detection complexity of the receiving terminal equipment, reducing the situation where the number of blind detections exceeds the maximum number of blind detections of the receiving terminal equipment, thus preventing the receiving terminal equipment from receiving data, and reducing the power consumption of the receiving terminal equipment. Specifically, this disclosure discloses a scheme for configuring the maximum number of sub-channels contained in the side-link resource pool when the number of candidate start symbols supported in one time slot is one. This disclosure provides a processing method for a "resource pool configuration" scenario, which reduces the number of sub-channels in the side link resource pool by configuring the maximum number of sub-channels in the side link resource pool to not exceed floor(N), thereby reducing the number of blind PSCCH detections by the receiving terminal device and reducing the power consumption of the receiving terminal device.

[0070] Figure 3 This is a flowchart illustrating a resource pool configuration method provided in an embodiment of this disclosure. The method is executed by a network device, such as... Figure 3 As shown, the method may include the following steps:

[0071] Step 301: Determine if a time slot in the sidelink resource pool supports two candidate start symbols;

[0072] Step 302: Configure the maximum number of sub-channels in the side-link resource pool to not exceed floor(N / 2), where N and K are both positive integers.

[0073] In one embodiment of this disclosure, the description of steps 301-302 can be found in the above-described embodiments, and this disclosure does not limit the scope of the embodiments. The optional examples in this disclosure can be arbitrarily combined, and without contradiction, this disclosure can be combined with steps from other embodiments and optional examples from other embodiments.

[0074] In one embodiment of this disclosure, the value of K can be, for example, 2. For instance, the number of candidate start symbols supported in a time slot can be 2.

[0075] Furthermore, in one embodiment of this disclosure, the time slot supports two candidate start symbols, and the maximum number of sub-channels does not exceed floor(N / 2).

[0076] For example, in one embodiment of this disclosure, for a 15kHz subcarrier spacing, N can be 44, K can be 2, and the maximum number of subchannels in the configuration-side link resource pool does not exceed 44 / 2 = 22; for a 30kHz subcarrier spacing, N can be 36, K can be 2, and the maximum number of subchannels in the configuration-side link resource pool does not exceed 36 / 2 = 18; for a 60kHz subcarrier spacing, N can be 22, K can be 2, and the maximum number of subchannels in the configuration-side link resource pool does not exceed 22 / 2 = 11; for a 120kHz subcarrier spacing, N can be 20, K can be 2, and the maximum number of subchannels in the configuration-side link resource pool does not exceed 20 / 2 = 10.

[0077] In summary, in the embodiments of this disclosure, it is determined that K candidate start symbols are supported in one time slot of the side-link resource pool; the maximum number of sub-channels contained in the side-link resource pool is configured not to exceed floor(N / 2), where N and K are both positive integers. In the embodiments of this disclosure, a resource pool configuration mechanism can be provided, which can configure the maximum number of sub-channels contained in the side-link resource pool, thereby limiting the number of sub-channels in the resource pool, reducing the blind detection complexity of the receiving terminal equipment, reducing the situation where the number of blind detections exceeds the maximum number of blind detections of the receiving terminal equipment, thus preventing the receiving terminal equipment from receiving data, and reducing the power consumption of the receiving terminal equipment. Specifically, this disclosure discloses a scheme for configuring the maximum number of sub-channels contained in the side-link resource pool when the number of candidate start symbols supported in one time slot is two. This disclosure provides a processing method for a "resource pool configuration" scenario, which reduces the number of sub-channels in the side-link resource pool by configuring the maximum number of sub-channels contained in the side-link resource pool to not exceed floor(N / 2K), thereby reducing the number of blind detections of PSCCH by the receiving terminal equipment and reducing the power consumption of the receiving terminal equipment.

[0078] Figure 4 This is a flowchart illustrating a resource pool configuration method provided in an embodiment of this disclosure. The method is executed by a network device, such as... Figure 4 As shown, the method may include the following steps:

[0079] Step 401: Determine N and K based on the subcarrier spacing;

[0080] Step 402: Determine if a time slot in the sidelink resource pool supports K candidate start symbols;

[0081] Step 403: Configure the maximum number of sub-channels in the side-link resource pool to not exceed floor(N / K), where N and K are both positive integers.

[0082] In one embodiment of this disclosure, the description of steps 401-403 can be found in the above-described embodiments, and this disclosure does not limit the scope of the embodiments. The optional examples in this disclosure can be arbitrarily combined, and without contradiction, this disclosure can be combined with steps from other embodiments and optional examples from other embodiments.

[0083] In one embodiment of this disclosure, for a subcarrier spacing of 15 kHz, the value of N can be, for example, 44; for a subcarrier spacing of 30 kHz, the value of N can be, for example, 36; for a subcarrier spacing of 60 kHz, the value of N can be, for example, 22; and for a subcarrier spacing of 120 kHz, the value of N can be, for example, 20.

[0084] For example, in one embodiment of this disclosure, for a 15kHz subcarrier spacing, N can be 44, K can be 1, and the maximum number of subchannels in the configuration-side link resource pool does not exceed 44; for a 30kHz subcarrier spacing, N can be 36, K can be 1, and the maximum number of subchannels in the configuration-side link resource pool does not exceed 36; for a 60kHz subcarrier spacing, N can be 22, K can be 1, and the maximum number of subchannels in the configuration-side link resource pool does not exceed 22; for a 120kHz subcarrier spacing, N can be 20, K can be 1, and the maximum number of subchannels in the configuration-side link resource pool does not exceed 20.

[0085] For example, in one embodiment of this disclosure, for a 15kHz subcarrier spacing, N can be 44, K can be 2, and the maximum number of subchannels in the configuration-side link resource pool does not exceed 44 / 2 = 22; for a 30kHz subcarrier spacing, N can be 36, K can be 2, and the maximum number of subchannels in the configuration-side link resource pool does not exceed 36 / 2 = 18; for a 60kHz subcarrier spacing, N can be 22, K can be 2, and the maximum number of subchannels in the configuration-side link resource pool does not exceed 22 / 2 = 11; for a 120kHz subcarrier spacing, N can be 20, K can be 2, and the maximum number of subchannels in the configuration-side link resource pool does not exceed 20 / 2 = 10.

[0086] In summary, in the embodiments of this disclosure, N and K are determined based on the subcarrier spacing; K candidate start symbols are supported in one time slot of the side-link resource pool; and the maximum number of sub-channels contained in the side-link resource pool is configured not to exceed floor(N / K), where N and K are both positive integers. This disclosure provides a resource pool configuration mechanism, which can configure the maximum number of sub-channels contained in the side-link resource pool, reducing the complexity of blind detection for the receiving terminal equipment, reducing the number of blind detections exceeding the maximum number of blind detections for the receiving terminal equipment, thus preventing the receiving terminal equipment from receiving data, and reducing the power consumption of the receiving terminal equipment. This disclosure specifically discloses a scheme for determining N and K based on the subcarrier spacing. This disclosure provides a processing method for the "resource pool configuration" scenario, which reduces the number of sub-channels in the side-link resource pool by configuring the maximum number of sub-channels contained in the side-link resource pool to not exceed floor(N / K), thereby reducing the number of blind detection PSCCHs by the receiving terminal equipment and reducing the power consumption of the receiving terminal equipment.

[0087] Figure 5 This is a flowchart illustrating a resource pool configuration method provided in an embodiment of this disclosure. The method is executed by a network device, such as... Figure 5 As shown, the method may include the following steps:

[0088] Step 501: Determine if a time slot in the sidelink resource pool supports K candidate start symbols;

[0089] Step 502: Configure the maximum number of resource block (RB) sets in the side-link resource pool to not exceed floor(N / (M*K)), where N and K are both positive integers, and M is the number of sub-channels included in an RB set.

[0090] In one embodiment of this disclosure, an unlicensed frequency band is applied to the side link.

[0091] In one embodiment of this disclosure, floor is used to indicate rounding down to the nearest integer. For example, floor(N / (M*K)) can indicate rounding down to the nearest integer for N / (M*K), such that floor(N / K) can be the largest integer not greater than N / (M*K).

[0092] Furthermore, in one embodiment of this disclosure, a candidate start symbol is supported in the time slot, and the maximum number of RB sets does not exceed floor (N / M).

[0093] For example, in one embodiment of this disclosure, it is determined that a candidate start symbol is supported in a time slot of the side link resource pool, and the maximum number of RB sets contained in the side link resource pool is configured not to exceed floor (N / M).

[0094] Furthermore, in one embodiment of this disclosure, two candidate start symbols are supported in the time slot, and the maximum number of RB sets does not exceed floor(N / 2M).

[0095] Furthermore, in one embodiment of this disclosure, it is determined that two candidate start symbols are supported in one time slot of the side link resource pool, and the maximum number of RB sets contained in the side link resource pool is configured not to exceed floor (N / 2M).

[0096] For example, in one embodiment of this disclosure, N is the maximum number of blind PSCCH detections supported by the terminal device in a time slot.

[0097] Furthermore, in one embodiment of this disclosure, N is the maximum number of blind detection PDCCHs supported by the reuse terminal device in a time slot.

[0098] In one embodiment of this disclosure, for a subcarrier spacing of 15 kHz, the value of N can be, for example, 44; for a subcarrier spacing of 30 kHz, the value of N can be, for example, 36; for a subcarrier spacing of 60 kHz, the value of N can be, for example, 22; and for a subcarrier spacing of 120 kHz, the value of N can be, for example, 20.

[0099] Furthermore, in one embodiment of this disclosure, the method further includes:

[0100] N and K are determined based on the subcarrier spacing.

[0101] For example, in one embodiment of this disclosure, when the subcarrier spacing is 15 kHz, the value of N can be, for example, 44, and the value of K can be, for example, 1. When one subchannel equals two interlaces, the value of M can be, for example, 5, that is, the maximum supported RB set does not exceed 8, floor(44 / (1×5))=8; when one subchannel equals one interlace, the value of M can be, for example, 10, that is, the maximum supported RB set does not exceed 4, that is, floor(44 / (1×10))=4.

[0102] For example, in one embodiment of this disclosure, when the subcarrier spacing is 15 kHz, the value of N can be, for example, 44, and the value of K can be, for example, 2. When one subchannel equals two interlaces, the value of M can be, for example, 5, that is, the supported RB set does not exceed 4, floor(44 / (2×5))=4; when one subchannel equals one interlace, the value of M can be, for example, 10, that is, the supported RB set does not exceed 2, floor(44 / (2×10))=2.

[0103] For example, in one embodiment of this disclosure, when the subcarrier spacing is 30 kHz, the value of N can be, for example, 36, and the value of K can be, for example, 1.
