Description

Communication method, device and storage medium TECHNICAL FIELD

[0001] The present disclosure relates to the technical field of communication, and particularly relates to a communication method, device and storage medium. BACKGROUND

[0002] The fifth generation mobile communication (5th Generation Mobile Communication Technology, 5G) supports two duplex technologies of time division duplex (Time Division Duplex, TDD) and frequency division duplex (Frequency Division Duplex, FDD). Compared with FDD, the uplink resources of TDD are less, which leads to the limited uplink coverage of TDD; at the same time, the uplink transmission opportunities of TDD are less, which leads to longer feedback delay of TDD. In order to solve this problem, 3GPP Release 18 / 19 introduces sub-band full duplex (Subband Full Duplex, SBFD) on the basis of TDD. Compared with TDD and FDD, advanced duplex technologies such as SBFD (including overlapping SBFD and non-overlapping SBFD), Flexible SBFD, in-band full duplex (In-band duplex, IBFD) and the like will introduce additional interference, including base station self-interference, gNB-gNB cross link interference (gNB-gNB Cross Link Interference, gNB-gNB CLI), UE-UE cross link interference (UE-UE Cross Link Interference) and the like.

In addition, a plurality of systems can be combined (for example, combination of LTE or LTE-A and 5G, and the like).

[0144] To facilitate understanding of the embodiments of the present disclosure, first, the concepts and symbols involved in the present disclosure are introduced.

[0145] 1. SBFD symbol: The SBFD symbol can divide the frequency band on the downlink symbol into one or more uplink subbands and one or more downlink subbands, and allow downlink transmission on the uplink subband of the downlink symbol.

[0146] 2. In-band duplex (IBFD) symbol: IBFD symbol allows simultaneous transmission and reception without alternating or time-division multiplexing the same frequency resource.

[0147] 3. Flexible SBFD symbol: Flexible SBFD symbol allows simultaneous transmission and reception in the same time period of a TDD system by splitting the channel into multiple subbands, implementing partial frequency bands for uplink transmission and partial frequency bands for downlink transmission.

[0148] 4、 denotes rounding down, denotes rounding up.

[0149] In some embodiments of the present disclosure, TDD is more widely deployed in actual networks. However, compared with FDD, TDD has less uplink resources, resulting in limited uplink coverage of TDD; at the same time, TDD has less uplink transmission opportunities, resulting in longer feedback delay of TDD. In order to solve this problem, 3GPP Release 18 / 19 introduces a new duplex technology based on TDD, namely subband full duplex (SBFD). SBFD includes subband overlapping full duplex and subband non-overlapping full duplex, and only subband non-overlapping full duplex is discussed in 3GPP Release 18 / 19. In addition to subband non-overlapping full duplex, other advanced duplex systems are also widely studied, such as: subband overlapping full duplex, flexible subband duplex, in-band duplex (IBFD), etc. For the present invention, any of the above advanced duplex systems can be applied, without limitation.

[0150] FIG. 1B is a schematic diagram of a subband non-overlapping full duplex according to an embodiment of the present disclosure. FIG. 1C is a schematic diagram of a subband overlapping full duplex / flexible subband full duplex according to an embodiment of the present disclosure. FIG. 1D is a schematic diagram of an IBFD according to an embodiment of the present disclosure. As shown in FIGS. 1B and 1C, X represents a subband duplex time slot / symbol. Compared with TDD, SBFD introduces uplink subbands on the frequency domain resources corresponding to downlink symbols and / or flexible symbols, which can be used for uplink transmission. Therefore, SBFD can effectively improve uplink coverage and reduce feedback delay.

[0151] Compared with conventional duplex technologies (TDD and FDD), advanced duplex technologies such as SBFD (including overlapping and non-overlapping), flexible SBFD, IBFD, etc. will introduce additional interference, including base station self-interference, gNB-gNB cross link interference (gNB-gNB CLI), UE-UE cross link interference (UE-UE CLI), etc. The base station self-interference is the interference caused by the base station transmitting downlink to its uplink, which can be caused by radio frequency leakage or environmental reflection. The gNB-gNB CLI refers to the interference of the base station downlink to the uplink of other base stations. The UE-UE CLI refers to the interference of the UE uplink to the downlink of other UEs. The present application is mainly used to suppress gNB-gNB CLI.

[0152] In some embodiments, in order to handle / suppress gNB-gNB CLI, the network device needs to send a reference signal on the CLI measurement resource, and other network devices measure the reference signal on the CLI measurement resource to obtain relevant information of gNB-gNB CLI, such as reference signal receiving power (RSRP), and / or gNB-gNB channel information, such as channel matrix H or relevant information obtained from channel matrix H, such as right singular vector after singular value decomposition (SVD) of H, precoding matrix indicator (PMI) obtained after quantization, etc.

[0153] In some embodiments, the CLI measurement resource can be configured between network devices, and the configuration method of the CLI measurement resource can include the following two methods:

[0154] Method 1: The central node configures the CLI measurement resource for each network node.

[0155] The central node can be an operations, administration and maintenance (OAM) module, or a gNB-central unit (CU), etc. The central node configures the CLI measurement resource for each network device, and each network device measures the reference signal according to the configured CLI measurement resource to obtain the information related to gNB-gNB CLI and / or gNB-gNB channel.

[0156] The advantage of method 1 is that the CLI measurement resource between each network device does not conflict, that is, there is no case that multiple network devices send reference signals on the same CLI measurement resource, otherwise, the reference signals sent by multiple network devices interfere with each other, resulting in reduced measurement performance. The disadvantage of method 1 is that the CLI measurement resource between other network devices is not flexible enough to be configured by the center node, and the CLI measurement resource is not easy to modify.

[0157] Method 2: The CLI measurement resource is configured by network devices.

[0158] The CLI measurement resource is configured by network devices. Compared with method 1, method 2 is more flexible; however, the CLI measurement resource between network devices is not easy to coordinate, resulting in that the reference signals are prone to conflict in time domain and / or frequency domain, and the measurement performance is reduced.

[0159] In summary, the disadvantage of method 1 is that the CLI measurement resource between other network devices is not flexible enough to be configured by the center node, and the CLI measurement resource is not easy to modify. The disadvantage of method 2 is that the CLI measurement resource between network devices is not easy to coordinate, and the reference signals are prone to conflict in time domain and / or frequency domain, resulting in that the reference signals sent by multiple network devices interfere with each other, and the measurement performance is reduced.

[0160] The present disclosure mainly solves the problem in method 2 described above, that is, the CLI measurement resource between network devices is configured, the reference signals are prone to conflict in time domain and / or frequency domain, resulting in that the reference signals sent by multiple network devices interfere with each other, and the measurement performance is reduced.

[0161] FIG. 2A is an interaction schematic diagram of a communication method according to an embodiment of the present disclosure. The method can be performed by the communication system described above. As shown in FIG. 2A, the method can include:

[0162] Step S2101, the first network device sends first information to the second network device.

[0163] In some embodiments, the second network device can receive the first information. For example, the second network device can receive the first information sent by the first network device. For another example, the second network device can also receive the first information sent by other entities.

[0164] In some embodiments, the first information can be used to configure at least one first resource.

[0165] In some embodiments, the first resource can be determined according to a physical cell identifier (PCI) of the first network device.

[0166] In some embodiments, the first resource can be a resource for the first network device to transmit the first signal, and also a resource for the second network device to receive the first signal.

[0169] In some embodiments, the first resource can be a Channel State Information-Reference Signal (CSI-RS) resource, and the first signal can be a CSI-RS.

[0170] It should be noted that the embodiments of the present disclosure take the first resource as a CSI-RS resource for example, and the method of the embodiments of the present disclosure is also applicable to other types of resources.

[0171] In some embodiments, the first resource is periodically repeated in the time domain, for example, the repetition period of the first resource can be T, and the unit is a time slot.

[0172] In some embodiments, the repetition period T of the first resource can be configured by a center node, for example, the center node can be an OAM or a gNB-CU.

[0173] In some embodiments, the first resource is a "comb" structure in the frequency domain.

[0174] Optionally, the density of the "comb" structure can be configured by the center node. For example, the "comb" structure means that the first resource is not allocated on a group of (in the frequency domain) continuous Resource Blocks (RBs), but is discretely and uniformly distributed in the frequency domain with an interval of 1 / density RBs. FIG. 2B is a frequency domain schematic diagram of a first resource according to an embodiment of the present disclosure. As shown in FIG. 2B, density=0.5, and the interval of the first resource in the frequency domain is 2 RBs.

[0175] In some embodiments, the determination manner of the first resource can include at least one of the following:

[0176] determining a time domain offset of the first resource according to the PCI;

[0177] determining a frequency domain offset of the first resource according to the PCI;

[0178] The time domain offset and the frequency domain offset of the first resource are determined according to the PCI.

[0179] In some embodiments, the first information is used to configure a first resource, and a time domain offset of the first resource can be determined according to the PCI of the first network device.

[0180] In some embodiments, the time domain offset of the first resource in the first period can be determined according to the PCI of the first network device.

[0184] It should be noted that the above-mentioned "slot" can be any slot, and it should be understood that the slot can include a "normal" (or "regular") slot and a first-type slot in the existing protocol.

[0185] In some embodiments, on the first-type symbol, the network device can simultaneously transmit and receive in a frequency band.

[0186] In some embodiments, if the unit of the first period T is a slot and a first-type slot, the time domain offset of the first resource can be determined by formula (1): offset = PCI mod T (1)

[0187] wherein T offset is the time domain offset of the first resource in the first period T, and PCI represents the PCI of the first network device.

[0188] In some embodiments, the time domain offset T offset of the first resource in the first period T indicates that the slot in which the first resource is located satisfies the following condition:

[0189] wherein μ represents a numerology, and the numerology is used to indicate a subcarrier spacing, n f represents a system frame number (SFN), and n This represents the slot number of a slot located within a system frame under parameter set μ.

[0190] Figure 2C is a schematic diagram illustrating a resource configuration according to an embodiment of the present disclosure. As shown in Figure 2C, T = 10, indicating that the first period T includes 10 time slots, of which 8 are first-type time slots and 2 are "normal" time slots. A first period T corresponds to PCI values ​​of 0-9, and a first period T corresponds to PCI values ​​of 10-19. For example, when PCI = 0, T... offset This indicates the first time slot within the first period T (in Figure 2C). Indicate #0), when PCI=1, T offset This indicates the second time slot within the first period T (in Figure 2C). Indicate #1), when PCI=2, T offset This indicates the third time slot within the first period T (in Figure 2C). Instruction #2), when PCI=3, T offset This indicates the 4th time slot within the first period T (in Figure 2C). Instruction #3), and so on, when PCI=9, T offset This indicates the 10th time slot within the first period T (in Figure 2C). Instruction #9).

[0191] In some embodiments, if the unit of the first period T′ is a first type of time slot, that is, the first resource is allocated on a first type of time slot and not on a "normal" time slot, then the time domain offset of the first resource in the first period T′ can be determined by formula (3): T′ offset =PCI mod T′ (3)

[0192] Among them, T′ offset The time-domain bias of the first resource within the first period T′.

[0193] In some embodiments, the time-domain offset T′ of the first resource within the first period T′ offset This indicates that the time slot containing the first resource meets the following conditions:

[0194] in, This represents the number of Class I time slots included in a system frame under parameter set μ. This represents the slot number of a first-class slot within a system frame under parameter set μ. The slot number of the first-class slot is the number of the first-class slots arranged in chronological order within a system frame.

[0195] FIG. 2D is a schematic diagram of resource configuration, according to an embodiment of the present disclosure. As shown in FIG. 2D, T' = 8, which means that the first period T' includes 8 first-type time slots, and the first period T' corresponds to the PCI = 0 ~ 7, and the first period T' corresponds to the PCI = 8 ~ 15. For example, when PCI = 0, T' = 0 ~ 7, which means that the first period T' includes the first-type time slots #0 ~ #7 in the first period T' (as shown in FIG. 2D). offset When PCI = 1, T' = 8 ~ 15, which means that the first period T' includes the first-type time slots #8 ~ #15 in the first period T' (as shown in FIG. 2D). When PCI = 2, T' = 16 ~ 23, which means that the first period T' includes the first-type time slots #16 ~ #23 in the first period T' (as shown in FIG. 2D). offset When PCI = 3, T' = 24 ~ 31, which means that the first period T' includes the first-type time slots #24 ~ #31 in the first period T' (as shown in FIG. 2D). When PCI = 4, T' = 32 ~ 39, which means that the first period T' includes the first-type time slots #32 ~ #39 in the first period T' (as shown in FIG. 2D). offset When PCI = 5, T' = 40 ~ 47, which means that the first period T' includes the first-type time slots #40 ~ #47 in the first period T' (as shown in FIG. 2D). When PCI = 6, T' = 48 ~ 55, which means that the first period T' includes the first-type time slots #48 ~ #55 in the first period T' (as shown in FIG. 2D). offset When PCI = 7, T' = 56 ~ 63, which means that the first period T' includes the first-type time slots #56 ~ #63 in the first period T' (as shown in FIG. 2D). When PCI = 8, T' = 64 ~ 71, which means that the first period T' includes the first-type time slots #64 ~ #71 in the first period T' (as shown in FIG. 2D). offset When PCI = 9, T' = 72 ~ 79, which means that the first period T' includes the first-type time slots #72 ~ #79 in the first period T' (as shown in FIG. 2D). When PCI = 10, T' = 80 ~ 87, which means that the first period T' includes the first-type time slots #80 ~ #87 in the first period T' (as shown in FIG. 2D).

[0196] It should be noted that the network device does not perform receiving and transmitting at the same time on the "normal" time slots, and the antenna panels used by the "normal" time slots and the first-type time slots can also be different, and therefore the RSRP and channel information between the network devices cannot be measured (or cannot be correctly measured) through the "normal" time slots.

[0197] In some embodiments, the first information is used to configure at least one first resource, for example, the first information can be used to configure K first resources, and K is a positive integer.

[0198] It should be noted that the "at least one first resource" in the embodiments of the present disclosure can also be referred to as "K first resources".

[0199] In some embodiments, the time domain offset of the at least one first resource can be determined according to the PCI and the first parameter K1, and K1 time units include the time units indicated by the time domain offset of the at least one first resource.

[0200] It should be noted that the "at least one first resource" can be understood as each first resource.

[0201] In some embodiments, if the unit of the first period T is a time slot, the time domain offset of the K first resources in the first period T satisfies formula (5) or formula (6): offset= (K1 x PCI + k1) mod T (5) T offset = (K1 x PCI) mod T + k1 (6)

[0202] wherein K1 is a positive integer, k1 = 0, 1, …, K1-1.

[0203] In some embodiments, the size relationship between K1 and K is not limited.

[0204] Optionally, K1 = 1, 2, …, T, or K1 = 1, 2, …, T-1.

[0205] In some embodiments, K1 can be configured to the first network device by the center node.

[0206] Optionally, the first parameter K1 configured by the center node for the whole network is the same.

[0207] Optionally, the first resource can include the first parameter K1.

[0209] Optionally, the K1 time units can be K1 time slots.

[0210] Optionally, the K1 time units can be K1 consecutive time slots.

[0211] In some embodiments, the first time unit of the K1 time units is determined according to the PCI. For example, if the K1 time units are K1 time slots, the first time slot of the K1 time slots can be determined according to the PCI. It should be understood that after determining the first time slot of the K1 time slots, the other K1-1 time slots can be determined.

[0212] In some embodiments, the first network device can determine how to allocate the K first resources in the K1 time units by itself.

[0213] Optionally, multiple first resources can be allocated on one time unit, or one first resource can be allocated. For example, multiple first resources can be allocated on one time slot, or one first resource can be allocated.

[0214] Optionally, the K1 time units can be all allocated to the first resource, or part of the K1 time units can be allocated to the first resource. For example, the K1 time slots can be all allocated to the first resource, or part of the K1 time slots can be allocated to the first resource.

[0215] FIG. 2E is a schematic diagram illustrating a resource configuration according to an embodiment of the present disclosure. As shown in FIG. 2E, T = 10, which indicates that the first period T includes 10 time slots, of which 8 are first type time slots and 2 are "normal" time slots. When the PCI is 0-4, one first period T is corresponded, and when the PCI is 5-9, one first period T is corresponded. Taking the first resource as an example of a CSI-RS resource, K = 4 and K1 = 2, which indicates that 2 time slots can be allocated to 4 CSI-RS resources (denoted as CSI-RS #0, CSI-RS #1, CSI-RS #2, and CSI-RS #3), and each PCI can correspond to 2 time slots. For example, when the PCI is 0, CSI-RS #0 / 1 can be allocated in the first time slot of the 2 time slots (denoted as #0 in FIG. 2E), and CSI-RS #2 / 3 can be allocated in the second time slot of the 2 time slots (denoted as #1 in FIG. 2E). Similarly, when the PCI is 4, CSI-RS #0 / 1 can be allocated in the first time slot of the 2 time slots (denoted as #8 in FIG. 2E), and CSI-RS #2 / 3 can be allocated in the second time slot of the 2 time slots (denoted as #9 in FIG. 2E).

[0216] In some embodiments, the first resource can include a third parameter, which can be used to indicate the time domain offset of the first resource.

[0217] It should be understood that the second network device can determine the time domain offset of the first resource through the third parameter in each first resource.

[0218] Optionally, the third parameter can be the time domain offset of the first resource.

[0219] It should be noted that the resource allocation manner given in the above FIG. 2E is exemplary, and the embodiments of the present disclosure are not limited thereto.

[0220] In some embodiments, the first network device can also allocate the K first resources on the K1 time units according to the first rule.

[0221] Optionally, the first rule can be a protocol agreement or pre-configuration.

[0222] Optionally, for each first resource, the time domain offset of the first resource can be determined according to the resource index of the first resource.

[0223] In some embodiments, the time domain offset of the first resource can be determined according to formula (7):

[0224] ​​​​wherein k represents a resource index of the first resource, k = 0, 1, …, K-1,

[0225] For example, taking FIG. 2E as an example, scale1 = 2, k = 0, 1, 2, 3, that is, the indexes of the four first resources are 0, 1, 2, and 3 respectively. When k = 0, k1 = 0, when k = 1, k1 = 0, when k = 2, k1 = 1, and when k = 3, k1 = 1. It should be understood that the first resources with resource indexes 0 and 1 correspond to the same time slot, and the first resources with resource indexes 2 and 3 correspond to the same time slot. The first resources with resource indexes 0 and 1 (CSI-RS #0 / 1 in FIG. 2E) can be allocated in the first time slot (indicated as #0 in FIG. 2E) of the two time slots, and the first resources with resource indexes 2 and 3 (CSI-RS #2 / 3 in FIG. 2E) can be allocated in the second time slot (indicated as #1 in FIG. 2E) of the two time slots.

[0226] In some embodiments, the first resource can include a fifth parameter for determining a time domain offset of the first resource.

[0227] Optionally, the fifth parameter can be the time domain offset of the first resource.

[0228] In some embodiments, the fifth parameter can be a resource index of the first resource.

[0229] It should be understood that the second network device can determine a time unit to which the first resource is allocated according to the resource index of the first resource. For example, if the resource index of the first resource is 2, it can be determined that the time slot to which the first resource is allocated is the second time slot of the two time slots.

[0230] In some embodiments, if the unit of the first period T' is the first type of time slot, the time domain offsets of the K first resources in the first period T' satisfy formula (8) or formula (9): offset T' = (K1 x PCI + k1) mod T' (8) T' offset = (K1 x PCI) mod T' + k1 (9)

[0231] In some embodiments, K1 represents that K1 time units can be allocated to the K first resources.

[0232] Optionally, the K1 time units can be K1 first type of time slots.

[0233] Optionally, the K1 time units can be K1 consecutive first type of time slots.

[0234] ​​In some embodiments, the first time unit of the K1 time units is determined according to the PCI. For example, if the K1 time units are K1 consecutive first type time slots, the first one of the K1 consecutive first type time slots can be determined according to the PCI. It should be understood that after the first time unit of the K1 time units is determined, the other K1-1 time units can be determined.

[0235] In some embodiments, the first network device can determine how to allocate the K first resources in the K1 time units by itself.

[0236] Optionally, one time unit can be allocated with one first resource or multiple first resources. For example, one first type time slot can be allocated with one first resource or multiple first resources.

[0237] Optionally, the K1 time units can be allocated with the first resources or part of the K1 time units can be allocated with the first resources. For example, the K1 first type time slots can be allocated with the first resources or part of the K1 first type time slots can be allocated with the first resources.

[0238] FIG. 2F is a schematic diagram of a resource configuration according to an embodiment of the present disclosure. As shown in FIG. 2F, T' = 8, indicating that the first period T' includes 8 first type time slots, and one first period T' corresponds to PCIs 0-3 and one first period T' corresponds to PCIs 4-7. Taking the first resource as a CSI-RS resource as an example, K = 4 and K1 = 2, indicating that 2 first type time slots can be allocated with 4 CSI-RS resources (indicated as CSI-RS #0, CSI-RS #1, CSI-RS #2, and CSI-RS #3), and each PCI can correspond to 2 first type time slots. For example, when PCI = 0, CSI-RS #0 / 1 can be allocated in the first one of the 2 first type time slots (indicated as #0 in FIG. 2F), and CSI-RS #2 / 3 can be allocated in the second one of the 2 first type time slots (indicated as #1 in FIG. 2F). Similarly, when PCI = 1, CSI-RS #0 / 1 can be allocated in the first one of the 2 first type time slots (indicated as #2 in FIG. 2F), and CSI-RS #2 / 3 can be allocated in the second one of the 2 first type time slots (indicated as #3 in FIG. 2F).

When PCI = 3, CSI-RS #0 / 1 can be allocated in the first one of the 2 first type time slots (indicated as #6 in FIG. 2F), and CSI-RS #2 / 3 can be allocated in the second one of the 2 first type time slots (indicated as #7 in FIG. 2F).

[0239] In some embodiments, the first resource can include a third parameter, which can be used to indicate a time domain offset of the first resource. ​​​​

[0240] It should be understood that the second network device can determine the time domain offset of the first resource through the third parameter in each first resource.

[0241] Optionally, the third parameter can be the time domain offset of the first resource.

[0242] It should be noted that the resource allocation manner shown in FIG. 2F is exemplary, and the embodiments of the present disclosure are not limited thereto.

[0243] In some embodiments, the first network device can also allocate the K first resources on K1 time units according to a first rule.

[0244] Optionally, the first rule can be a protocol agreement or pre-configuration.

[0245] Optionally, for each first resource, the time domain offset of the first resource can be determined according to the resource index of the first resource.

[0246] In some embodiments, the time domain offset of the first resource can be determined according to formula (7).

[0247] Taking FIG. 2F as an example, scale1=2, k=0, 1, 2, 3, that is, the indexes of the four first resources are 0, 1, 2, and 3. When k=0, k1=0, when k=1, k1=0, when k=2, k1=1, and when k=3, k1=1. It should be understood that the first resources with indexes 0 and 1 correspond to the same first type of time slot, and the first resources with indexes 2 and 3 correspond to the same first type of time slot. The first resources with indexes 0 and 1 (CSI-RS#0 / 1 in FIG. 2F) can be allocated in the first first type of time slot (indicated as #0 in FIG. 2F) of the two first type of time slots, and the first resources with indexes 2 and 3 (CSI-RS#2 / 3 in FIG. 2F) can be allocated in the second first type of time slot (indicated as #1 in FIG. 2F) of the two first type of time slots. . .

[0248] In some embodiments, the first resource can include a fifth parameter, and the fifth parameter is used to determine the time domain offset of the first resource.

[0249] Optionally, the fifth parameter can be the time domain offset of the first resource.

[0250] In some embodiments, the fifth parameter can be the resource index of the first resource.

[0251] It should be understood that the second network device can determine the time unit allocated by the first resource according to the resource index of the first resource. For example, if the resource index of the first resource is 2, it can be determined that the first type time slot allocated by the first resource is the second first type time slot in the two first type time slots.

[0252] In some embodiments, the first information is used to configure a first resource, and a frequency domain offset of the first resource can be determined according to the PCI of the first network device.

[0253] In some embodiments, the frequency domain offset of the first resource can be determined by formula (10): RB offset = PCI mod (1 / density) (10)

[0254] RB offset is the frequency domain offset of the first resource, and density represents the density of the frequency domain units allocated to the first resource. For example, if density = 0.5, it means that the interval of the frequency domain units allocated to the first resource is 2 frequency domain units.

[0255] In some embodiments, the frequency domain unit can be RB.

[0256] It should be noted that the embodiments of the present disclosure take RB as the frequency domain unit for illustration, and the specific implementation of other types of frequency domain units can be referred to RB.

[0257] In some embodiments, the time domain offset RB offset of the first resource satisfies formula (11) or formula (12): (n RB -RB offset ) mod (1 / density) = 0 (11) (n RB -1 / density + RB offset ) mod (1 / density) = 0 (12)

[0258] RB RB is the index of RB, n RB = 0, 1, …, n RB is numbered in the order of increasing frequency from the reference point as the starting point.

[0259] Optionally, the reference point can be CRB0.

[0260] FIG. 2G is a schematic diagram of a resource configuration according to an embodiment of the present disclosure. As shown in FIG. 2G, density = 0.5, which means that the interval of the RBs allocated to the first resource is 2. For example, when PCI = 0, RB offsetindicates the 1st RB and the 3rd RB (n RB indicates #0 and #2), at PCI = 1, the RB offset indicates the 2nd RB and the 4th RB (n RB indicates #1 and #3).

[0261] It is to be noted that the allocation of part of RB resources is shown in FIG. 2G, and other RB resources can be allocated according to the above allocation manner, which will not be described herein.

[0264] Optionally, the K2 frequency domain units can be K2 RBs.

[0265] Optionally, the K2 frequency domain units can be K2 consecutive RBs.

[0266] In some embodiments, the frequency domain offset of the K first resources in the frequency domain is RB offset determined according to the PCI of the first network device.

[0267] In some embodiments, if the frequency domain unit is an RB, the frequency domain offset of the K first resources in the frequency domain is RB offset satisfies formula (13) and formula (14): RB offset = (K2 x PCI + k2) mod (1 / density) (13) RB offset = (K2 x PCI) mod (1 / density) + k2 (14)

[0268] wherein k2 = 0, 1, …, K2-1, and K2 is a positive integer.

[0269] In some embodiments, the first frequency domain unit of the K2 frequency domain units is determined according to the PCI. For example, if the K2 frequency domain units are K2 consecutive RBs, the first RB of the K2 consecutive RBs can be determined according to the PCI. It should be understood that after determining the first RB of the K2 consecutive RBs, the other K2-1 consecutive RBs can be determined.

[0270] In some embodiments, the first network device can determine how to allocate the K first resources in the K2 RBs by itself.

[0271] Optionally, the K2 RBs can be all allocated to the first resource, or part of the RBs can be allocated to the first resource.

[0272] FIG. 2H is a schematic diagram of a resource configuration according to an embodiment of the present disclosure. As shown in FIG. 2H, density = 0.25, which means that the interval of the RBs allocated to the first resource is 4, K = 2, and K2 = 2, which means that 2 RBs can be allocated to 2 CSI-RS resources. For example, when PCI = 0, CSI-RS #0 is allocated to the 1st RB (indicated by #0 in FIG. 2H) of the 2 RBs, and CSI-RS #1 is allocated to the 2nd RB (indicated by #1 in FIG. 2H) of the 2 RBs.

[0274] It should be understood that the second network device can determine the frequency domain offset of the first resource through the fourth parameter in each first resource.

[0275] Optionally, the fourth parameter can be the frequency domain offset of the first resource.

[0276] It should be noted that the resource allocation mode given in the above FIG. 2H is exemplary, and the embodiments of the present disclosure are not limited thereto.

[0277] In some embodiments, the first network device can also allocate the K first resources on the K2 RBs according to a second rule.

[0278] Optionally, the second rule can be a protocol agreement or pre-configuration.

[0279] In some embodiments, K2 can be greater than or equal to K.

[0280] Optionally, K2 = 1, 2, …, 1 / density, or K2 = 1, 2, …, 1 / density-1.

[0281] In some embodiments, K2 can be configured to the first network device by a center node.

[0282] Optionally, the second parameter K2 configured by the center node for the entire network is the same.

[0283] ​​​​Optionally, the first resource can comprise a second parameter K2.

[0284] Optionally, for each first resource, a frequency domain offset of the first resource can be determined according to a resource index of the first resource.

[0286] wherein k represents the resource index of the first resource, k = 0, 1, …, K-1.

[0287] For example, in FIG. 2H, K2 = 2, k = 0, 1, i.e., the indices of the two first resources are 0, 1 respectively. When k = 0, k2 = 0, and when k = 1, k2 = 1. It should be understood that the first resource with resource index 0 (CSI-RS #0 in FIG. 2H) corresponds to the 1st RB (n RB indicated in FIG. 2H) of the 2 RBs, and the first resource with resource index 1 (CSI-RS #1 in FIG. 2H) corresponds to the 2nd RB (n RB indicated in FIG. 2H) of the 2 RBs.

[0288] In some embodiments, the first resource can comprise a fifth parameter, the fifth parameter being used to determine a frequency domain offset of the first resource.

[0289] Optionally, the fifth parameter can be the frequency domain offset of the first resource.

[0290] In some embodiments, the fifth parameter can be a resource index of the first resource.

[0291] It should be understood that the second network device can determine the RB allocated to the first resource according to the resource index of the first resource. For example, if the resource index of the first resource is 1, it can be determined that the RB allocated to the first resource is the 2nd RB of the 2 RBs.

[0347] In some embodiments, the first network device can determine how to allocate the K first resources on the K1 time units and the K2 RBs by itself.

[0348] For example, multiple first resources can be allocated on one time slot, or one first resource can be allocated on one time slot.

[0349] For example, multiple first resources can be allocated on one first type of time slot, or one first resource can be allocated on one first type of time slot.

[0350] For example, the K1 time slots can be all allocated to the first resources, or part of the time slots can be allocated to the first resources.

[0351] For example, the K1 first type of time slots can be all allocated to the first resources, or part of the first type of time slots can be allocated to the first resources.

[0352] For example, the K2 RBs can be all allocated to the first resources, or part of the RBs can be allocated to the first resources.

[0353] In some embodiments, the first resource can comprise a third parameter and a fourth parameter, the third parameter can be used to indicate a time domain offset of the first resource, and the fourth parameter can be used to indicate a frequency domain offset of the first resource.

[0354] It should be understood that the second network device can determine the time domain offset of each first resource through the third parameter in the first resource, and determine the frequency domain offset of each first resource through the fourth parameter in the first resource.

[0355] Optionally, the third parameter can be the time domain offset of the first resource.

[0357] In some embodiments, the first network device can also allocate the K first resources on the K1 time units and the K2 RBs according to a third rule.

[0358] Optionally, the third rule can be a protocol agreement or pre-configuration.

[0359] In some embodiments, the first resource can comprise a fifth parameter, which is used to determine a time domain offset and a frequency domain offset of the first resource.

[0360] Optionally, the fifth parameter can comprise a time domain offset and a frequency domain offset of the first resource.

[0361] In some embodiments, the fifth parameter can be a resource index of the first resource.

[0362] In some embodiments, the second network device can first determine the RBs allocated to the first resource according to the resource index of the first resource, and then determine the slots (or the first type of slots) allocated to the first resource.

[0363] For example, the frequency domain offset of the first resource can be determined according to formula (30) first, and then the time domain offset of the first resource can be determined according to formula (31): R = k mod K2 (30)

[0364] wherein,

[0365] For example, scale2 = 1, k = 0, 1, 2, 3, i.e., the indexes of the four CSI-RS resources are 0, 1, 2, and 3. It should be understood that, for each PCI, the CSI-RS resources associated with the PCI can be allocated on the RBs and slots associated with the PCI. For example, when PCI = 0 (for convenience of description, denoted as PCI 0), the RBs associated with PCI 0 are the RBs with indexes 0 and 1, the slots associated with PCI 0 are the slots with indexes 0 and 1, and the four CSI-RS resources (CSI-RS#0, CSI-RS#1, CSI-RS#2, CSI-RS#3) associated with PCI 0 can be allocated on the RBs with indexes 0 and 1 and the slots with indexes 0 and 1. It should be understood that the RBs and slots allocated to the four CSI-RS resources associated with PCI 0 can be determined in the order of frequency domain first and then time domain.

[0366] When k = 0, k2 = 0, when k = 1, k2 = 1, when k = 2, k2 = 0, and when k = 3, k2 = 1. It can be seen that the CSI-RS resource with index 0 (CSI-RS#0) and the CSI-RS resource with index 2 (CSI-RS#2) correspond to the same RB, and the CSI-RS resource with index 1 (CSI-RS#1) and the CSI-RS resource with index 3 (CSI-RS#3) correspond to the same RB. It should be understood that CSI-RS#0 and CSI-RS#2 associated with PCI 0 are allocated to the RB with index 0, and CSI-RS#1 and CSI-RS#3 associated with PCI 0 are allocated to the RB with index 1.

[0367] At k = 0, k1 = 0, at k = 1, k1 = 0, at k = 2, k1 = 1, at k = 3, k1 = 1. It can be seen that the slots corresponding to CSI-RS#0 and CSI-RS#1 are the same, and the slots corresponding to CSI-RS#2 and CSI-RS#3 are the same. It should be understood that the CSI-RS#0 and CSI-RS#1 associated with PCI 0 are allocated to the slot with index 0, and the CSI-RS#2 and CSI-RS#3 associated with PCI 0 are allocated to the slot with index 1.

[0368] It should be noted that the CSI-RS resource associated with a PCI is the resource configured by the cell indicated by the PCI for other network devices, and the resources configured by different cells for other network devices are different. It should be understood that the CSI-RS resources associated with different PCIs are different, for example, the CSI-RS#0 associated with PCI 0 is different from the CSI-RS#0 associated with PCI 1 (PCI = 1).

[0369] It should also be noted that Table 1 is a resource allocation table according to FIG. 2I, which shows the allocation of CSI-RS resources associated with PCIs = 0 ~ 9. The resource allocation method of other PCIs can refer to the above description of PCI = 0, which will not be repeated here.

[0370] Table 1

[0371] Taking FIG. 2J as an example, scale2 = 1, k = 0, 1, 2, 3, that is, the indexes of the four first CSI-RSs are 0, 1, 2, and 3 respectively. For example, the RBs associated with PCI 0 are the RBs with indexes 0 and 1, the first type of slots associated with PCI 0 are the first type of slots with indexes 0 and 1, and the four CSI-RS resources (CSI-RS#0, CSI-RS#1, CSI-RS#2, CSI-RS#3) associated with PCI 0 can be allocated on the RBs with indexes 0 and 1 and the first type of slots with indexes 0 and 1. It should be understood that the RBs and the first type of slots allocated to the four CSI-RS resources associated with PCI 0 can be determined in the order of frequency domain first and time domain second.

[0372] At k=0, k2=0, at k=1, k2=1, at k=2, k2=0, at k=3, k2=1. It can be seen that the CSI-RS resource with index 0 (CSI-RS#0) and the CSI-RS resource with index 2 (CSI-RS#2) correspond to the same RB, and the CSI-RS resource with index 1 (CSI-RS#1) and the CSI-RS resource with index 3 (CSI-RS#3) correspond to the same RB. It should be understood that the CSI-RS#0 and the CSI-RS#2 associated with the PCI 0 are allocated the RB with index 0, and the CSI-RS#1 and the CSI-RS#3 associated with the PCI 0 are allocated the RB with index 1.

[0373] At k=0, k1=0, at k=1, k1=0, at k=2, k1=1, at k=3, k1=1. It can be seen that the CSI-RS#0 and the CSI-RS#1 correspond to the same first type of slot, and the CSI-RS#2 and the CSI-RS#3 correspond to the same first type of slot. It should be understood that the CSI-RS#0 and the CSI-RS#1 associated with the PCI 0 are allocated the first type of slot with index 0, and the CSI-RS#2 and the CSI-RS#3 associated with the PCI 0 are allocated the first type of slot with index 1.

[0374] It should be noted that Table 2 is a resource allocation table according to FIG. 2J, which shows the allocation of the CSI-RS resources associated with the PCIs=0~9. The resource allocation method of other PCIs can refer to the description of the PCI=0 above, and will not be described here.

[0375] Table 2

[0376] For example, the time domain offset of the first resource can be determined according to formula (32) first, and the frequency domain offset of the first resource can be determined according to formula (33) second.

[0377] For example, the RB associated with the PCI 0 is the RB with index 0 and 1, the slot associated with the PCI 0 is the slot with index 0 and 1, and the four CSI-RS resources (CSI-RS#0, CSI-RS#1, CSI-RS#2, CSI-RS#3) associated with the PCI 0 can be allocated on the RB with index 0 and 1 and the slot with index 0 and 1. It should be understood that the slot and the RB allocated to the four CSI-RS resources associated with the PCI 0 can be determined in the order of time domain first and frequency domain second.

[0378] At k=0, k1=0, at k=1, k1=1, at k=2, k1=0, at k=3, k1=1. It can be seen that the slots corresponding to CSI-RS#0 and CSI-RS#2 are the same, and the slots corresponding to CSI-RS#1 and CSI-RS#3 are the same. It should be understood that the CSI-RS#0 and CSI-RS#2 associated with PCI 0 are allocated to the slot with index 0, and the CSI-RS#1 and CSI-RS#3 associated with PCI 0 are allocated to the slot with index 1.

[0379] At k=0, k2=0, at k=1, k2=0, at k=2, k2=1, at k=3, k2=1. It can be seen that the RBs corresponding to CSI-RS#0 and CSI-RS#1 are the same, and the RBs corresponding to CSI-RS#2 and CSI-RS#3 are the same. It should be understood that the CSI-RS#0 and CSI-RS#1 associated with PCI 0 are allocated to the RB with index 0, and the CSI-RS#2 and CSI-RS#3 associated with PCI 0 are allocated to the RB with index 1.

It should be understood that the first type of slots and RBs allocated to the four CSI-RS resources associated with PCI 0 can be determined in the order of time domain first and frequency domain second.

[0383] At k=0, k1=0, at k=1, k1=1, at k=2, k1=0, at k=3, k1=1. It can be seen that the first type of time slots corresponding to CSI-RS#0 and CSI-RS#2 are the same, and the first type of time slots corresponding to CSI-RS#1 and CSI-RS#3 are the same.

[0387] In some embodiments, when performing the communication method of the embodiments of the present disclosure, at least one of the following conditions can be included:

[0388] Global SFN synchronization;

[0389] Global T (or T') is the same;

[0390] Global K1 is the same;

[0391] Global K2 is the same;

[0392] Global reference point is the same.

[0393] In some embodiments, for global SFN synchronization, the network devices can interact the SFN of the first reference time. The first reference time can be the Coordinated Universal Time (UTC) time, for example, the first reference time is 1990-01-01 00:00:00. It should be understood that this method can help the network devices to synchronize the SFN.

[0394] Step S2102. The first network device sends the first signal to the second network device according to the first resource.

[0395] In some embodiments, the second network device can receive the first signal. For example, the second network device can receive the first signal sent by the first network device. For another example, the second network device can also receive the first signal sent by other entities.

[0401] It should be noted that the specific manner of performing the gNB-gNB CLI suppression scheme can refer to the existing protocol, which will not be described here.

[0402] By using the above method, the time-frequency resources in the first resource are associated with the PCI of the network device. Since the PCI of each network device is different, the time-frequency resources of the first resource of each network device are also different, that is, the time-frequency resources of the first resource are randomized, thereby reducing or even eliminating the collision of the reference signal on the time-frequency resources, and further reducing the interference between the first signals sent by multiple network devices and improving the measurement performance.

[0403] In some embodiments, the above steps are optional steps.

[0404] In some embodiments, the other optional implementation manners described before or after the corresponding description of FIG. 2A can be referred to.

[0464] In some embodiments, the present disclosure proposes a CLI measurement resource configuration method, which specifically includes:

[0465] The time domain and / or frequency domain location of the CLI measurement resource is associated with a physical cell identifier (PCI).

[0466] 1. The time offset of the CLI measurement resource is determined according to the PCI.

[0467] (1) The time offset of the CLI measurement resource is determined according to the PCI and the CLI measurement resource index;

[0468] (2) The count of the system frame number (SFN) between all network devices is synchronized;

[0469] (3) The period of the CLI measurement resource between all network devices is the same.

[0470] 2. The frequency offset of the CLI measurement resource is determined according to the PCI.

[0471] (1) The frequency offset of the CLI measurement resource is determined according to the PCI and the CLI measurement resource index;

[0472] (2) The frequency density of the CLI measurement resource between all network devices is the same.

[0473] 3. The time domain offset and the frequency offset of the CLI measurement resource are determined according to the PCI.

[0474] (1) The CLI measurement resource of each cell is first allocated in the frequency domain, and then allocated in the time domain;

[0475] (2) The CLI measurement resource of each cell is first allocated in the time domain, and then allocated in the frequency domain;

[0476] (3) For each cell, the CLI measurement resource is first allocated in the frequency domain, and then allocated in the time domain, or

[0477] (4) For each cell, the CLI measurement resource is first allocated in the time domain, and then allocated in the frequency domain.

[0478] In some embodiments, the CLI measurement resource configuration method of the present disclosure can include the following steps:

[0479] Step 1-1, the first network device sends first information to the second network device, and the first information is used to configure the first resource.

[0480] Step 1-2, the second network device receives the first information sent by the first network device, and determines the first resource according to the first information.

[0481] Step 2-1, the first network device sends a first signal to the second network device according to the first resource.

[0482] Step 2-2, the second network device receives the first signal sent by the first network device according to the first resource.

[0483] Optionally, the first resource is a channel state information-reference signal (CSI-RS) resource, and the first signal is a CSI-RS.

[0484] It should be understood that the first signal is used for the second network device to measure the channel information between the first network device and the second network device, or the first signal is used for the second network device to measure the received power of the first signal, i.e. RSRP. The first network device and / or the second network device can perform a reasonable gNB-gNB CLI suppression scheme according to the channel information between the first network device and the second network device, and / or the RSRP corresponding to the first signal. The channel information includes but is not limited to channel matrix H and related information determined according to channel matrix H, such as right singular vector of SVD decomposition of channel matrix H, or PMI determined according to channel matrix H, etc.

[0485] It should be understood that the first resource is the resource for the first network device to send the first signal, and is also the resource for the second network device to receive the first signal. The first resource includes but is not limited to time domain resource, frequency domain resource, space domain resource, sequence parameter, power control parameter, etc. for sending and / or receiving the first signal.

[0486] Optionally, the first resource is periodically repeated in time domain. For example, the repetition period of the first resource is T, unit: time slot. Further optionally, the repetition period T of the first resource is configured by a center node. For example, the center node is OAM or gNB-CU, etc.

[0487] Optionally, the first resource is in a comb structure in the frequency domain. Further optionally, a density of the comb structure is configured by the central node. Illustratively, the comb structure refers to the first resource not being allocated on a set of contiguous resource blocks (RBs) in the frequency domain, but being discretely and uniformly distributed in the frequency domain with an interval of 1 / density RBs, as shown in FIG. 2B.

[0488] Optionally, the time-domain resource and / or the frequency-domain resource of the first resource is determined according to the PCI of the first network device. Specifically, the following possible schemes are included.

[0489] Scheme 1: The time-domain resource of the first resource is determined according to the PCI of the first network device.

[0490] Method 1-1: Offset T of the first resource in a period T offset determined according to the PCI of the first network device. Illustratively, T offset = PCI mod T, as shown in FIG. 2C. It should be understood that offset T offset refers to a time slot in which the first resource is located satisfying the following condition:

[0491] wherein μ represents a numerology used to indicate a configuration of a subcarrier spacing, n represents a number of time slots included in a system frame under the numerology μ, f SFN represents a system frame number, n represents a time slot number of a time slot located in a system frame under the numerology μ.

[0492] Method 1-2: Offset T' of the first resource in a period T' offset determined according to the PCI of the first network device. Illustratively, T' offset = PCI mod T', as shown in FIG. 2D. It should be understood that T' represents a period of the first resource, and the unit is a first type time slot, which is different from a “regular” time slot. The first type time slot includes at least one first type symbol. On the first type symbol, a network device can simultaneously transmit and receive in a frequency band, i.e., the first type symbol is a symbol supporting advanced duplex technology, such as SBFD, IBFD, Flexible SBFD, etc. Offset T' offset refers to a time slot in which the first resource is located satisfying the following condition:

[0493] wherein μ represents a numerology used to indicate a configuration of a subcarrier spacing, indicates the number of first type slots included in a system frame under a numerology μ, indicates the slot number of a first type slot within a system frame under a numerology μ, wherein the slot number of the first type slot refers to the numbering in time sequence only for the first type slot within a system frame.

[0494] It should be understood that, compared with method 1-1, method 1-2 will not allocate the first resources on the “normal” slots, because the network devices will not transmit and receive at the same time on the “normal” slots, and the antenna panels used on the two types of slots can also be different, so the RSRP and channel information between the network devices cannot be measured (or cannot be measured correctly).

[0495] Optionally, the “the first information is used to configure the first resources” further includes that the first information is used to configure at least one first resource. For ease of description, it is assumed that the first information configures K first resources, where K≥1. For method 1-1 and method 1-2 of scheme 1, it can be extended as:

[0496] Method 1-3: the offset T of K first resources in a period T offset determined according to the PCI of the first network device. Exemplarily, the offset of K first resources satisfies the condition:

[0497] T offset = (K1×PCI+k1) mod T, or, T offset = (K1×PCI) mod T+k1,

[0498] k1=0,1,…,K1-1, where K1 is a positive integer. It should be understood that K1 indicates that K1 consecutive slots can be used to allocate K first resources; further, how the first network device allocates K first resources on the K1 consecutive slots includes two methods:

[0499] Method 1-3-1: the first network device determines how to allocate K first resources on the K1 consecutive slots by itself; wherein multiple first resources can be allocated on one slot, or only one first resource can be allocated on one slot, and K1 slots can be all used to allocate the first resources, or only part of the slots can be used to allocate the first resources. It should be understood that, for method 1-3-1, each first resource of K first resources must include a time domain offset T offset parameter, so that the second network device can correctly understand the time domain resources of K first resources.

[0500] Method 1-3-2: The first network device allocates K first resources on K1 consecutive time slots according to a fixed rule. Optionally, the time domain resource of the first resource is also determined according to the index k of the first resource, k = 0, 1, …, K-1. Exemplarily, It should be understood that for method 1-3-2, each of the K first resources must include the index k parameter, and does not need to include the time domain offset T offset parameter, the second network device can determine the time domain resource of the K first resources according to the same rule.

[0501] Optionally, the parameter K1 is configured to the first network device by a central node. Further optionally, the central node configures the same parameter K1 for the whole network; further optionally, the first resource includes the parameter K1.

[0502] It should be understood that the size relationship between K1 and K is not limited. Optionally, K1 = 1, 2, …, T or K1 = 1, 2, …, T-1.

[0503] Exemplarily, FIG. 2E shows an example of method 1-3.

[0504] Method 1-4: The offset T′ offset of the K first resources in a period T′ is determined according to the PCI of the first network device. Exemplarily, the offset of the K first resources satisfies the condition: T′ offset = (K1×PCI+k1) mod T′, or, T′ offset = (K1×PCI) mod T′+k1,

[0505] k1 = 0, 1, …, K1-1, where K1 is a positive integer. It should be understood that K1 indicates that K1 consecutive time slots can be used to allocate the K first resources; further, how the first network device allocates the K first resources on the K1 consecutive time slots includes two methods:

[0506] Method 1-4-1: The first network device determines how to allocate the K first resources on the K1 consecutive time slots by itself; wherein one time slot can allocate multiple first resources, or can only allocate one first resource, and K1 time slots can be all used to allocate the first resources, or can only be partially used to allocate the first resources. It should be understood that for method 1-4-1, each of the K first resources must include the time domain offset T′ offset parameter, so that the second network device can correctly understand the time domain resource of the K first resources.

[0507] Method 1-4-2: The first network device allocates K first resources on K1 consecutive time slots according to a fixed rule. Optionally, the time domain resource of the first resource is also determined according to the index k of the first resource, k = 0, 1, …, K-1. Exemplarily, It should be understood that for method 1-4-2, each of the K first resources must include the index k parameter, and does not need to include the time domain offset T' offset parameter, the second network device can determine the time domain resource of the K first resources according to the same rule.

[0508] Optionally, the parameter K1 is configured to the first network device by a central node. Further optionally, the central node configures the same parameter K1 for the whole network; further optionally, the first resource includes the parameter K1.

[0509] It should be understood that the size relationship between K1 and K is not limited. Optionally, K1 = 1, 2, …, T' or K1 = 1, 2, …, T'-1.

[0510] Exemplarily, FIG. 2F shows an example of method 1-4.

[0511] Scheme 2: The frequency domain resource of the first resource is determined according to the PCI of the first network device.

[0512] Method 2-1: The offset RB offset of the first resource in the frequency domain is determined according to the PCI of the first network device. Exemplarily, RB offset = PCI mod(1 / density),

[0513] As shown in FIG. 2G. It should be understood that the offset RB offset means that the RB where the first resource is located needs to satisfy the following condition: (n RB -RB offset )mod(1 / density) = 0, or (n RB -1 / density + RB offset )mod(1 / density) = 0.

[0514] Wherein, n RB is the index of RB, n RB = 0, 1, …, n RB is numbered in the order of increasing frequency with the reference point as the starting point; optionally, the reference point is CRB0.

[0515] Optionally, the “the first information is used to configure the first resource” further includes that the first information is used to configure at least one first resource.

[0516] For convenience of description, it is assumed that the first information configures K first resources, where K≥1. For method 2-1, it can be extended as:

[0517] Method 2-2: the offset RB of K first resources in the frequency domain offset According to the PCI of the first network device. Exemplarily, the offset RB of K first resources in the frequency domain satisfies the condition: RB offset =(K2×PCI+k2)mod(1 / density), or, RB offset =(K2×PCI)mod(1 / density)+k2,

[0518] k2=0,1,…,K2-1, where K2 is a positive integer. It should be understood that K2 represents that K2 consecutive RBs can be used to allocate K first resources; further, how the first network device allocates K first resources on K2 consecutive RBs includes two methods:

[0519] Method 2-2-1: the first network device determines how to allocate K first resources on K2 consecutive RBs by itself, where K2 RBs can be used to allocate the first resources, or only part of RBs can be used to allocate the first resources. It should be understood that for method 2-2-1, each of the K first resources must include the frequency domain offset RB offset parameter, so that the second network device can correctly understand the frequency domain resource of K first resources.

[0520] Method 2-2-2: the first network device allocates K first resources on K2 consecutive RBs according to a fixed rule. Optionally, the frequency domain resource of the first resource is also determined according to the index k of the first resource, k=0,1,…,K-1. Exemplarily, k2=k mod K2. It should be understood that for method 2-2-2, each of the K first resources must include the index k, and does not need to include the frequency domain offset RB offset , so that the second network device can determine the frequency domain position of K first resources according to the same rule.

[0521] Optionally, the parameter K2 is configured to the first network device by a center node. Further optionally, the center node configures the same parameter K2 for the whole network; further optionally, the first resource includes the parameter K2.

[0522] It should be understood that the size relationship between K2 and K is: K2≥K. Optionally, K2=1,2,…,1 / density or K2=1,2,…,1 / density-1.

[0523] For example, FIG. 2H shows an example of the above method.

[0524] In scheme 3, the time domain resource and the frequency resource of the first resource are jointly determined according to the PCI of the first network device.

[0525] Generally, the offset T offset and the offset RB offset of each of the K first resources in the time domain are jointly determined according to the PCI of the first network device. It should be understood that scheme 3 is equivalent to the combination of scheme 1 and scheme 2. According to different sub-methods under scheme 1 and scheme 2, different new methods can be combined under scheme 3, which specifically include the following methods:

[0526] Method 3-1: the offset RB offset of the K first resources in the frequency domain satisfies the condition:

[0527] RB offset = (K2 x PCI + k2) mod (1 / density), or,

[0528] RB offset = (K2 x PCI) mod (1 / density) + k2,

[0529] k2 = 0, 1, …, K2-1; and the offset T offset of the K first resources in the time domain satisfies the condition:

[0530] or,

[0531] or,

[0532] or,

[0533] k1 = 0, 1, …, K1-1. It should be understood that in the frequency domain, K2 consecutive RBs can be used to allocate the first resource; in the time domain, K1 consecutive (first type) time slots can be used to allocate the first resource; for different network devices, as the PCI increases, the time-frequency resources that can be used to allocate the first resource are arranged in the order of frequency domain first and then time domain. For example, method 3-1 is shown in FIG. 2I.

[0534] Method 3-2: the offset T offset of the K first resources in the time domain satisfies the condition:

[0535] T offset = (K1 x PCI + k1) mod T, or,

[0536] T offset = (K1 x PCI + k1) mod T, or,

[0537] T′ offset = (K1 x PCI + k1) mod T, or, offset = (K1 x PCI) mod T + k1,

[0538] k1 = 0, 1,..., K1-1; meanwhile, the offset RB offset of K first resources in frequency domain satisfies the condition:

[0539] or,

[0540] or,

[0541] or,

[0542] k2 = 0, 1,..., K2-1. It should be understood that in time domain, K1 consecutive (first type) time slots can be used to allocate the first resources; in frequency domain, K2 consecutive RBs can be used to allocate the first resources; for different network devices, as PCI increases, the time-frequency resources available for allocating the first resources are arranged in the order of time domain first and then frequency domain. For example, method 3-2 is shown in FIG. 2J.

[0543] Optionally, how the first network device allocates K first resources on K1 consecutive time slots and K2 consecutive RBs includes the following two methods:

[0544] Method 3-x-1: the first network device determines how to allocate K first resources on K1 consecutive time slots and K2 consecutive RBs by itself; wherein, one time slot can allocate multiple first resources, or only one first resource, K1 time slots can be used to allocate the first resources, or only part of the time slots can be used to allocate the first resources, K2 RBs can be used to allocate the first resources, or only part of the RBs can be used to allocate the first resources. It should be understood that for this method, each of the K first resources must include time domain offset T offset and frequency domain offset RB offset parameters, so that the second network device can correctly understand the time domain resources and frequency domain resources of the K first resources.

[0545] Method 3-x-2: The first network device allocates K first resources according to a fixed rule on K1 continuous time slots and K2 continuous RBs. Optionally, the time domain resource and the frequency domain resource of the first resource are also determined according to the index k of the first resource, k = 0, 1, …, K-1, including the following two examples:

[0546] For example, It should be understood that the time-frequency resources of the K first resources are arranged in the order of frequency domain first and time domain second;

[0547] For example, It should be understood that the time-frequency resources of the K first resources are arranged in the order of time domain first and frequency domain second;

[0548] It should be understood that for method 3-x-2, each of the K first resources must include the index k, and does not need to include the time domain offset T offset and the frequency domain offset RB offset The second network device can determine the time domain resource and the frequency domain resource of the K first resources according to the same rule.

[0549] For example, method 3-1 and method 3-x-1 are shown in FIG. 2I and FIG. 2J, and method 3-2 and method 3-x-2 are shown in FIG. 2K and FIG. 2L.

[0550] Optionally, for scheme 1 and scheme 3, at least one or more of the following restrictions are met:

[0551] Condition 1: SFN synchronization across the network;

[0552] Condition 2: T (or T') is the same across the network;

[0553] Condition 3: K1 is the same across the network;

[0554] Condition 4: K2 is the same across the network;

[0555] Condition 5: The reference point is the same across the network.

[0556] Optionally, for the condition 1, the network devices interact with each other on the SFN of the first reference time. The first reference time is UTC time; for example, the first reference time is January 1, 1990 00:00:00. It should be understood that this method can help the network devices to synchronize the SFN.

[0557] The embodiments of the present disclosure associate the time-frequency resources in the CLI measurement resource with the PCI of the network device. Since the PCI of each network device is different, the time-frequency resources of the CLI measurement resource of each network device are also different, that is, the time-frequency resources of the CLI measurement resource are randomized, thereby reducing or even eliminating the collision of the reference signals on the time-frequency resources, and further reducing the interference between the reference signals sent by multiple network devices, and improving the measurement performance.
