[0031] Figure 1 is a schematic diagram of an application scenario according to an embodiment of the present description.

[0032] As shown in Figure 1, the embodiments of this description can be applied to a scenario where a terminal communicates with a network device, but are not limited to that scenario. The entities shown in Figure 1 are illustrative. Implementations or embodiments of this description may include all or part of the entities in Figure 1, and may also include other entities not shown in Figure 1. The number of entities is arbitrary and is not limited to Figure 1. The connection relationships shown in Figure 1 are illustrative. Any entities may or may not be connected, and the connection may be of any form, direct or indirect, wired or wireless.

[0033] In one embodiment, the network device can configure a sub-band for the terminal, for example, it can configure an uplink sub-band for the terminal in a first slot, and it can configure a downlink sub-band for the terminal in a second slot.

[0034] The first slot includes at least one of the following: a downlink slot or a flexible slot. The second slot includes at least one Petition 870260001187, dated 07 / 01 / 2026, page 12 / 161 / 70 of the following: an uplink slot or a flexible slot.

[0035] The network device can perform full-duplex communication in the first slot and the second slot. Therefore, the first and second slots can also be called Sub-band Full Duplex (SBFD) slots, where the first slot is an SBFD slot configured with an uplink subband and the second slot is an SBFD slot configured with a downlink subband. The terminal can be a terminal capable of half-duplex communication in an SBFD slot. For example, in an SBFD slot, the terminal can perform uplink transmission but cannot simultaneously receive downlink transmission, or it can receive downlink transmission but cannot simultaneously perform uplink transmission. The terminal can be a terminal that supports the SBFD feature and can also be referred to as an SBFD-compatible terminal.

[0036] Figure 2 is a schematic diagram of uplink resources and downlink resources according to an embodiment of the present description.

[0037] As shown in Figure 2, an activated bandwidth portion (BWP) corresponding to a downlink timedomain unit includes an uplink subband, a guard band, and a downlink subband, where the network device configures an uplink subband and a guard band for the terminal in the downlink timedomain unit. In the frequency domain resources corresponding to the downlink timedomain unit, the frequency domain resources other than the uplink subband and the guard band can be referred to as the downlink subband. The frequency domain resources in the uplink subband can serve as uplink resources, the frequency domain resources in the downlink subband Petition 870260001187, dated 07 / 01 / 2026, page 13 / 161 / 70 downlink can serve as downlink resources, and the guard band cannot be used to transmit information, where the information includes data and / or signals, thus achieving frequency domain isolation to a certain extent and avoiding interference between uplink communication and downlink communication. Alternatively, when the network device programs only uplink transmission or only downlink transmission, a guard band is not necessary for frequency domain isolation between uplink and downlink, and the guard band can be used for data transmission.

[0038] In one embodiment, the time domain unit includes at least one of the following elements: a frame, a subframe, a slot, a symbol, wherein the symbol may be an Orthogonal Frequency Division Multiplexing (OFDM) symbol.

[0039] It should be noted that the embodiments of the present description may be applicable to situations where a guard band is provided between an uplink subband and a downlink subband, and may also be applicable to situations where no guard band is provided between an uplink subband and a downlink subband.

[0040] In one embodiment, the network device can configure a CSI-RS resource for the endpoint, and the endpoint can receive the CSI-RS on the CSI-RS resource configured by the network device.

[0041] Because the related technique does not consider SBFD slots and there are no uplink and / or downlink subbands in the BWP, the minimum number of configurable frequency domain resources for the CSI-RS feature is determined based on the BWP. However, if the network device configures an uplink and / or downlink subband in the BWP for the terminal, slots will exist. Petition 870260001187, dated 07 / 01 / 2026, page 14 / 161 / 70 SBFD, meaning that not all frequency domain resources in a BWP are used for downlink communication, and not all for uplink communication.

[0042] Taking a downlink slot as an example, an uplink sub-band can be configured in the BWP corresponding to the downlink slot. Then, the resources effectively available for CSI-RS transmission must be the frequency domain resources within the BWP, except in the uplink sub-band. For example, when the guard band is not considered, the resource used for CSI-RS transmission is the downlink sub-band. If the minimum value of configurable frequency domain resources for the CSI-RS resource is still determined based on the BWP, in some cases, the minimum value of configurable frequency domain resources for the CSI-RS resource may be determined as equal to the BWP, but the terminal cannot actually receive CSI-RS in the uplink sub-band within the BWP, i.e., the frequency domain resources in which the terminal actually receives CSI-RS are smaller than the BWP.Therefore, this can cause inconsistencies in the understanding of the CSI-RS feature between the network device and the terminal.

[0043] In one embodiment, the configurable frequency domain resources of the CSI-RS resource can be distinguished by the count of frequency domain resource units. For example, the frequency domain resource unit includes at least one of the following: a Resource Block (RB), a Resource Element (RE).

[0044] In one embodiment, the terminal includes, but is not limited to, a mobile phone, a tablet, a wearable device, a sensor, an Internet of Things device, and other communication devices. The terminal can communicate with a network device, and the network device includes, but is not limited to, network devices in systems of Petition 870260001187, dated 07 / 01 / 2026, page 15 / 161 / 70 communication such as 4G, 5G, 6G, for example, a base station, a core network, etc.

[0045] Figure 3 is a schematic flowchart of a method for determining resources according to an embodiment of the present description. The method for determining resources shown in this embodiment can be performed by a terminal.

[0046] As shown in Figure 3, the method for determining the resources may include the following steps: Step S301: Receive a Channel State Information Reference Signal (CSI-RS) based on a channel state information reference signal resource, wherein a count of configurable frequency domain resource units of the channel state information reference signal resource is greater than or equal to a minimum between a first count and a second count, and the second count is a count of frequency domain resource units occupied by a first frequency domain resource capable of receiving downlink transmission.

[0047] In one embodiment, when configuring the CSI-RS resource for the terminal, the network device may first determine a first frequency domain resource available to the terminal to receive downlink transmission and determine the second count of frequency domain resource units occupied by the first frequency domain resource. Then, based on the minimum between the first and second counts, the minimum frequency domain resource unit count of the CSI-RS resource configured for the terminal is determined. Thus, the frequency domain resource unit count of the CSI-RS resource configured by the network device for the terminal will not be less than the minimum between the first count and the second count.

[0048] Correspondingly, the terminal can determine a Petition 870260001187, dated 07 / 01 / 2026, page 16 / 161 / 70 first frequency domain resource capable of receiving downlink transmission and determining the count of frequency domain resource units occupied by the first frequency domain resource, for example, referred to as the second count. Then, the terminal can receive the CSI-RS and determine that the count of configurable frequency domain resource units of the CSI-RS is greater than or equal to the minimum between the first and second counts, which can also be described as not expecting the count of configurable frequency domain resource units of the CSI-RS resource to be less than the minimum between the first and second counts. Consequently, it is beneficial to ensure that the understanding of the CSI-RS resource by the network device and the terminal is consistent, in order to ensure the quality of subsequent communication between the network device and the terminal.

[0049] Alternatively, the terminal determines the CSI-RS resource according to a protocol agreement or network device configuration information and receives the CSI-RS according to the CSI-RS resource, wherein the relationship between the configurable frequency domain resource unit count of the CSI-RS resource and the minimum between the first and second count is agreed upon by the protocol or determined by the network device, and does not necessarily require terminal participation; for example, the configurable frequency domain resource unit count of the CSI-RS resource is greater than or equal to the minimum between the first and second count.In this case, the terminal does not necessarily need to perform one or more of the following actions: determine a first frequency domain resource capable of receiving downlink transmission; determine the count of frequency domain resource units occupied by the first frequency domain resource; determine that the count of configurable frequency domain resource units of the CSI-RS is greater than or equal to the minimum between a. Petition 870260001187, dated 07 / 01 / 2026, page 17 / 161 / 70 first and second count; do not expect the CSI-RS configurable frequency domain resource unit count to be less than the minimum between the first count and the second count.

[0050] In one mode, the first count is determined based on a predefined rule or is configured by the network device. For example, when the frequency domain resource unit is an RB, the first count might be 24.

[0051] For example, the terminal determines that the frequency domain resource unit count occupied by the first frequency domain resource capable of receiving downlink transmission is 10, that is, the second count is 10. Then, the terminal determines that the configurable frequency domain resource unit count of the CSI-RS is greater than or equal to min {24, 10}, and / or does not expect the configurable frequency domain resource unit count of the CSI-RS resource to be less than min {24, 10}. where min {24, 10} is 10, then the terminal determines that the configurable frequency domain resource unit count of the CSI-RS is greater than or equal to 10, and / or does not expect the configurable frequency domain resource unit count of the CSI-RS resource to be less than 10.

[0052] Alternatively, the terminal determines the CSI-RS resource according to a protocol agreement or network device configuration information and receives the CSI-RS according to the CSI-RS resource, where the relationship between the configurable frequency domain resource unit count of the CSI-RS resource and the minimum of the first count and the second count is agreed upon by the protocol or determined by the network device and does not necessarily require terminal participation, for example, the configurable frequency domain resource unit count of the CSI-RS resource is greater than or equal to min {24, 10}. In this case, the terminal does not necessarily need to perform one or more Petition 870260001187, dated 07 / 01 / 2026, page 18 / 161 / 70 of the following actions: determine a first frequency domain resource capable of receiving downlink transmission; determine the count of frequency domain resource units occupied by the first frequency domain resource; determine that the count of configurable frequency domain resource units of the CSI-RS is greater than or equal to min {24, 10}; do not expect the count of configurable frequency domain resource units of the CSI-RS to be less than min {24, 10}.

[0053] The first frequency domain resource capable of receiving downlink transmission is described below, by way of example, through various modes.

[0054] In one embodiment, the first frequency domain resource capable of being used to receive downlink transmission includes at least one of: a downlink subband; a guard band.

[0055] In one embodiment, the downlink subband includes at least one of: a frequency domain resource, configured in a downlink slot, that is not an uplink subband; a frequency domain resource, configured in a downlink slot, that is not an uplink subband and a guard band; a frequency domain resource, configured in a flexible slot, that is not an uplink subband; a frequency domain resource, configured in a flexible slot, that is not an uplink subband and a guard band; a downlink subband configured in an uplink slot; a downlink subband configured in a flexible slot.

[0056] For example, the network device configures an uplink sub-band for the terminal in a downlink slot. Frequency domain features in frequency domain features Petition 870260001187, dated 07 / 01 / 2026, page 19 / 161 / 70 corresponding to the downlink slot, which are not in the uplink sub-band, may be referred to as the downlink sub-band, and the terminal may receive downlink transmission in the downlink sub-band. In this case, the first frequency domain resource capable of being used to receive downlink transmission includes frequency domain resources in the frequency domain resources corresponding to the downlink slot, except in the uplink sub-band.

[0057] For example, the network device configures an uplink subband and a guard band for the terminal in a downlink slot. The frequency domain resources in the frequency domain resources corresponding to the downlink slot, other than the uplink subband, and the guard band can be referred to as a downlink subband, and the terminal can receive downlink transmission in the downlink subband. In this case, the first frequency domain resource capable of being used to receive downlink transmission includes frequency domain resources in the frequency domain resources corresponding to the downlink slot, except for the uplink subband and the guard band.

[0058] For example, the network device configures an uplink subband for the terminal in a flexible slot. The frequency domain resources in the frequency domain resources corresponding to the flexible slot, other than the uplink subband, can be referred to as a downlink subband, and the terminal can receive downlink transmissions in the downlink subband. In this case, the first frequency domain resource capable of being used to receive downlink transmission includes frequency domain resources in the frequency domain resources of Petition 870260001187, dated 07 / 01 / 2026, page 20 / 161 / 70 frequencies corresponding to the flexible slot, except in the uplink sub-band.

[0059] For example, the network device configures an uplink subband and a guard band for the terminal in a flexible slot. The frequency domain resources in the frequency domain resources corresponding to the flexible slot, other than the uplink subband and the guard band, can be referred to as a downlink subband, and the terminal can receive downlink transmission in the downlink subband. In this case, the first frequency domain resource capable of being used to receive downlink transmission includes frequency domain resources in the frequency domain resources corresponding to the flexible slot, except for the uplink subband and the guard band.

[0060] For example, the network device configures a downlink subband for the terminal in an uplink slot. The terminal can receive downlink transmission in the downlink subband. In this case, the first frequency domain resource capable of being used to receive the downlink transmission includes the downlink subband in the uplink slot.

[0061] For example, the network device configures a downlink subband for the terminal in a flexible slot. The terminal can receive downlink transmission in the downlink subband. In this case, the first frequency domain resource capable of being used to receive downlink transmission includes the downlink subband in the flexible slot.

[0062] In one embodiment, the first frequency domain resource capable of receiving downlink transmission includes: continuous frequency domain resources capable of receiving downlink transmission, wherein the information reference signal resource Petition 870260001187, dated 07 / 01 / 2026, page 21 / 161 / 70 of channel status includes continuous frequency domain resource units.

[0063] That is, when the CSI-RS resource includes continuous frequency domain resource units, the first frequency domain resource capable of receiving downlink transmission may include continuous frequency domain resources capable of receiving downlink transmission.

[0064] In one embodiment, if the first frequency domain resource that the terminal can use to receive downlink transmission includes a downlink subband, the terminal can determine the downlink subband in which the initial frequency domain resource unit is located as the first frequency domain resource.

[0065] For example, if there is only one downlink subband in the enabled BWP, the terminal can determine that downlink subband as the first frequency domain resource. Based on the mode shown in Figure 2, there are two downlink subbands in the enabled BWP, and the two downlink subbands are discontinuous. So, when the CSI-RS resource includes continuous frequency domain resource units, the first frequency domain resource capable of receiving downlink transmission can be one of these two downlink subbands.Therefore, when there are multiple continuous frequency domain resources capable of receiving downlink transmission, considering that the CSI-RS resource can only include continuous frequency domain resources, the CSI-RS resource can only be transmitted on one of the continuous frequency domain resources, and the terminal needs to determine one continuous frequency domain resource as the first frequency domain resource.

[0066] Determining a frequency domain feature Petition 870260001187, dated 07 / 01 / 2026, page 22 / 161 / 70 continuous as the first frequency domain resource among multiple continuous frequency domain resources capable of receiving downlink transmission is described in an exemplary manner below through various modalities.

[0067] In one embodiment, the first frequency domain resource capable of receiving downlink transmission includes: a continuous frequency domain resource that is capable of receiving downlink transmission based on an initial frequency domain resource unit of the channel state information reference signal resource.

[0068] The network device can send CSI-RS resource configuration information to the terminal, and the terminal can determine the CSI-RS resource based on the configuration information. For example, the configuration information includes at least one of: an initial frequency domain resource unit of the CSI-RS resource, or a count of continuous frequency domain resource units.

[0069] The terminal can determine, among multiple continuous frequency domain resources capable of receiving downlink transmission, the continuous frequency domain resource that is capable of receiving downlink transmission based on the initial frequency domain resource unit as the first frequency domain resource.

[0070] By way of example, a count of frequency domain resource units by which the initial frequency domain resource unit of the CSI-RS resource is shifted from an initial frequency domain resource unit of a common CRB resource block no. 0 may be a positive integer multiple of a first value.

[0071] Figure 4 is a schematic diagram of a first frequency domain feature, according to a modality of Petition 870260001187, dated 07 / 01 / 2026, page 23 / 161 / 70 present description.

[0072] As shown in Figure 4, based on the mode shown in Figure 2, two downlink sub-bands can be determined in the activated BWP, which are downlink sub-band #1 and downlink sub-band #2. If the terminal determines, according to the CSI-RS resource configuration information, that the initial frequency domain resource unit of the CSI-RS resource is in downlink sub-band #1, then downlink sub-band #1 can be determined as the first frequency domain resource capable of receiving downlink transmission.

[0073] Taking as an example the frequency domain resource unit, including RBs, for example, in Figure 4, downlink sub-band #1 includes 12 RBs and downlink sub-band #2 includes 10 RBs. If downlink sub-band #1 is used as the first frequency domain resource capable of receiving downlink transmission based on the analysis above, the second count will be equal to the number of RBs contained in downlink sub-band #1, that is, 12 RBs. Then, the terminal determines that the count of configurable frequency domain resource units of the CSI-RS is greater than or equal to min {24, 12}, and / or does not expect the count of configurable frequency domain resource units of the CSI-RS resource to be less than min {24, 12}.where min {24, 12} is 12, then the terminal determines that the CSI-RS configurable frequency domain resource unit count is greater than or equal to min {24, 12}, and / or does not expect the CSI-RS configurable frequency domain resource unit count to be less than 12.

[0074] Alternatively, the terminal determines the CSI-RS resource according to a protocol agreement or network device configuration information and receives the CSI-RS according to the CSI-RS resource, in Petition 870260001187, dated 07 / 01 / 2026, page 24 / 161 / 70 that the relationship between the configurable frequency domain resource unit count of the CSI-RS resource and the minimum of the first count and the second count is agreed upon by the protocol or determined by the network device and does not necessarily require terminal participation, for example, the configurable frequency domain resource unit count of the CSI-RS resource is greater than or equal to min {24, 12}.In this case, the terminal does not necessarily need to perform one or more of the following actions: determine a first frequency domain resource capable of receiving downlink transmission; determine the count of frequency domain resource units occupied by the first frequency domain resource; determine that the CSI-RS configurable frequency domain resource unit count is greater than or equal to min {24, 12}; do not expect the CSI-RS configurable frequency domain resource unit count to be less than min {24, 12}.

[0075] In one embodiment, if the first frequency domain resource that the terminal can use to receive downlink transmission includes a downlink subband and a guard band, the terminal can determine the downlink subband in which the initial frequency domain resource unit is located and the guard band connected to the downlink subband as the first frequency domain resource.

[0076] For example, when the initial frequency domain resource unit of the CSI-RS resource is in downlink subband #1 or guard band #1, downlink subband #1 and guard band #1 connected to downlink subband #1 can be determined as the first frequency domain resource capable of receiving downlink transmission. The second count is equal to the sum of the number of RBs contained in the downlink subband. Petition 870260001187, dated 07 / 01 / 2026, page 25 / 161 / 70 No. 1 and in guard band No. 1, that is, 12 2=14. Therefore, the terminal determines that the CSI-RS configurable frequency domain resource unit count is greater than or equal to min {24, 14}, and / or does not expect the CSI-RS configurable frequency domain resource unit count to be less than min {24, 14}. where min {24, 14} is 14, therefore, the terminal determines that the CSI-RS configurable frequency domain resource unit count is greater than or equal to min {24, 14}, and / or does not expect the CSI-RS configurable frequency domain resource unit count to be less than 14.

[0077] Alternatively, the terminal determines the CSI-RS resource according to a protocol agreement or network device configuration information and receives the CSI-RS according to the CSI-RS resource, wherein the relationship between the configurable frequency domain resource unit count of the CSI-RS resource and the minimum of the first count and the second count is agreed upon by the protocol or determined by the network device and does not necessarily require terminal participation, for example, the configurable frequency domain resource unit count of the CSI-RS resource is greater than or equal to min {24, 14}.In this case, the terminal does not necessarily need to perform one or more of the following actions: determine a first frequency domain resource capable of receiving downlink transmission; determine the count of frequency domain resource units occupied by the first frequency domain resource; determine that the CSI-RS configurable frequency domain resource unit count is greater than or equal to min {24, 14}; do not expect the CSI-RS configurable frequency domain resource unit count to be less than min {24, 14}.

[0078] In one embodiment, the first domain resource of Petition 870260001187, dated 07 / 01 / 2026, page 26 / 161 / 70 frequency capable of receiving downlink transmission includes: a continuous frequency domain resource, among all continuous frequency domain resources capable of receiving downlink transmission, that occupies a lower frequency domain unit count.

[0079] When the terminal has multiple continuous frequency domain resources capable of receiving downlink transmission, the terminal can determine the frequency domain unit count occupied by each continuous frequency domain resource and use the continuous frequency domain resource that occupies the lowest frequency domain unit count as the first frequency domain resource.

[0080] In one embodiment, if the first frequency domain resource that the terminal can use to receive downlink transmission includes a downlink subband, the terminal can determine the frequency domain unit count occupied by each downlink subband and determine the downlink subband that occupies the lowest frequency domain unit count as the first frequency domain resource.

[0081] Figure 5 is a schematic diagram of another first frequency domain feature, according to an embodiment of the present description.

[0082] As shown in Figure 5, based on the mode shown in Figure 2, two downlink sub-bands can be determined in the activated BWP, which are downlink sub-band #1 and downlink sub-band #2. The terminal determines, according to the CSI-RS feature configuration information, that the initial frequency domain feature unit of the CSI-RS feature is in downlink sub-band #2, therefore, downlink sub-band #2 can be determined as the first frequency domain feature. Petition 870260001187, dated 07 / 01 / 2026, page 27 / 161 / 70 capable of receiving transmission of a downward link.

[0083] Taking the frequency domain resource unit, including RBs, as an example, in Figure 5, downlink sub-band #1 includes 12 RBs and downlink sub-band #2 includes 10 RBs. Therefore, between the two downlink sub-bands, downlink sub-band #2 occupies the smaller number of RBs. Therefore, downlink subband #2 can be used as the first frequency domain resource capable of receiving downlink transmission, so the second count is 10. Thus, the terminal determines that the CSI-RS configurable frequency domain resource unit count is greater than or equal to min {24, 10}, and / or does not expect the CSI-RS resource configurable frequency domain resource unit count to be less than min {24, 10}.where min {24, 10} is 10, then the terminal determines that the CSI-RS configurable frequency domain resource unit count is greater than or equal to min {24, 10}, and / or does not expect the CSI-RS configurable frequency domain resource unit count to be less than 10.

[0084] Alternatively, the terminal determines the CSI-RS resource according to a protocol agreement or network device configuration information and receives the CSI-RS according to the CSI-RS resource, where the relationship between the configurable frequency domain resource unit count of the CSI-RS resource and the minimum of the first count and the second count is agreed upon by the protocol or determined by the network device and does not necessarily require terminal participation, for example, the configurable frequency domain resource unit count of the CSI-RS resource is greater than or equal to min {24, 10}. In this case, the terminal does not necessarily need to perform one or more of the following actions: determine a first frequency domain resource of Petition 870260001187, dated 07 / 01 / 2026, page 28 / 161 / 70 frequency capable of receiving downlink transmission; determine the count of frequency domain resource units occupied by the first frequency domain resource; determine that the CSI-RS configurable frequency domain resource unit count is greater than or equal to min {24, 10}; do not expect the CSI-RS configurable frequency domain resource unit count to be less than min {24, 10}.

[0085] In one embodiment, if the first frequency domain resource that the terminal can use to receive downlink transmission includes a downlink subband and a guard band, the terminal can determine the downlink subband that occupies the lowest frequency domain unit count and the guard band connected to the downlink subband as the first frequency domain resource.

[0086] For example, between the count of frequency domain units occupied by downlink subband #1 and guard band #1 connected to downlink subband #1 and the count of frequency domain units occupied by downlink subband #2 and guard band #2 connected to downlink subband #2, the count of frequency domain units occupied by downlink subband #2 and guard band #2 connected to downlink subband #2 is the smaller. Downlink subband #2 and guard band #2 connected to downlink subband #2 can be determined as the first frequency domain resource capable of receiving downlink transmission. The second count is equal to the sum of the number of RBs contained in the downlink sub-band #2 and the guard band #2, that is, 10 ÷ 2 = 12.Therefore, the terminal determines that the count of configurable frequency domain resource units of the CSI-RS is greater than or equal to. Petition 870260001187, dated 07 / 01 / 2026, page 29 / 161 / 70 min {24, 12}, and / or does not expect the configurable frequency domain resource unit count of the CSI-RS resource to be less than min {24, 12}. where min {24, 12} is 12, then the terminal determines that the configurable frequency domain resource unit count of the CSI-RS is greater than or equal to min {24, 12}, and / or does not expect the configurable frequency domain resource unit count of the CSI-RS resource to be less than 12.

[0087] Alternatively, the terminal determines the CSI-RS resource according to a protocol agreement or network device configuration information and receives the CSI-RS according to the CSI-RS resource, wherein the relationship between the configurable frequency domain resource unit count of the CSI-RS resource and the minimum of the first count and the second count is agreed upon by the protocol or determined by the network device and does not necessarily require terminal participation, for example, the configurable frequency domain resource unit count of the CSI-RS resource is greater than or equal to min {24, 12}.In this case, the terminal does not necessarily need to perform one or more of the following actions: determine a first frequency domain resource capable of receiving downlink transmission; determine the count of frequency domain resource units occupied by the first frequency domain resource; determine that the CSI-RS configurable frequency domain resource unit count is greater than or equal to min {24, 12}; do not expect the CSI-RS configurable frequency domain resource unit count to be less than min {24, 12}.

[0088] It should be noted that the method of determining a continuous frequency domain resource as the first frequency domain resource among multiple continuous frequency domain resources capable of receiving downlink transmission is not limited to the method Petition 870260001187, dated 07 / 01 / 2026, page 30 / 161 / 70 described in the modalities above. For example, the first frequency domain resource capable of receiving downlink transmission includes: a continuous frequency domain resource, among all continuous frequency domain resources capable of receiving downlink transmission, that occupies a higher frequency domain unit count; for example, the first frequency domain resource capable of receiving downlink transmission includes: a continuous frequency domain resource, among all continuous frequency domain resources capable of receiving downlink transmission, that is indicated by the network device (for example, the network device may indicate a frequency domain resource identifier, a frequency domain range, etc.).For example, the first frequency domain resource capable of receiving downlink transmission includes: a continuous frequency domain resource, among all continuous frequency domain resources capable of receiving downlink transmission, where the count of occupied frequency domain units is an integer multiple of a first value (for example, 4).If multiple conditions exist, other conditions (such as identifier, initial frequency domain resource unit) can be combined to determine, for example, the continuous frequency domain resource corresponding to the smallest identifier that satisfies the above condition as the first frequency domain resource capable of receiving downlink transmission; for example, the first frequency domain resource capable of receiving downlink transmission includes: a continuous frequency domain resource, among all continuous frequency domain resources capable of receiving downlink transmission, whose identifier is a predefined identifier (e.g., the smallest identifier or the largest identifier).

[0089] In one embodiment, the first domain resource of Petition 870260001187, dated 07 / 01 / 2026, page 31 / 161 / 70 frequency capable of receiving downlink transmission includes a non-continuous frequency domain resource capable of receiving downlink transmission, wherein the channel state information reference signal resource may include non-continuous frequency domain resource units.

[0090] That is, where the CSI-RS resource can include non-continuous frequency-domain resource units, the first frequency-domain resource capable of receiving downlink transmission can include a non-continuous frequency-domain resource capable of receiving downlink transmission. It should be noted that this does not mean that the first frequency-domain resource cannot include a continuous frequency-domain resource capable of receiving downlink transmission, but rather that the first frequency-domain resource can include both a continuous frequency-domain resource capable of receiving downlink transmission and a non-continuous frequency-domain resource capable of receiving downlink transmission.

[0091] In one embodiment, if the first frequency domain resource that the terminal can use to receive downlink transmission includes a downlink subband, the terminal can determine the count of frequency domain units occupied by all downlink subbands as the first frequency domain resource.

[0092] For example, if there is only one downlink subband in the activated BWP, the terminal can determine that downlink subband as the first frequency domain feature. Based on the mode shown in Figure 2, there are two downlink subbands in the activated BWP, and the two downlink subbands are discontinuous. So, when the CSI-RS feature includes feature units of Petition 870260001187, dated 07 / 01 / 2026, page 32 / 161 / 70 non-continuous frequency domain, the first frequency domain resource capable of receiving downlink transmission may be these two downlink sub-bands.

[0093] Using Figure 5 as an example, based on the modality shown in Figure 2, the terminal can determine two downlink subbands, which are downlink subband #1 and downlink subband #2. The terminal can determine downlink subband #1 and downlink subband #2 as the first frequency domain resource capable of receiving downlink transmission.

[0094] Taking as an example the frequency domain resource unit, including RBs, for example, in Figure 5, downlink sub-band #1 includes 12 RBs and downlink sub-band #2 includes 10 RBs. The total number of RBs contained in the two downlink sub-bands is 22, so the second count is 22. Therefore, the terminal determines that the count of configurable frequency domain resource units of the CSI-RS is greater than or equal to min {24, 22}, and / or does not expect the count of configurable frequency domain resource units of the CSI-RS resource to be less than min {24, 22}. where min {24, 22} is 22, then the terminal determines that the CSI-RS configurable frequency domain resource unit count is greater than or equal to min {24, 22}, and / or does not expect the CSI-RS configurable frequency domain resource unit count to be less than 22.

[0095] Alternatively, the terminal determines the CSI-RS resource according to a protocol agreement or network device configuration information and receives the CSI-RS according to the CSI-RS resource, where the ratio between the configurable frequency domain resource unit count of the CSI-RS resource and the minimum of the first Petition 870260001187, dated 07 / 01 / 2026, page 33 / 161 / 70 The first count and the second count are agreed upon by the protocol or determined by the network device and do not necessarily require the terminal's participation, for example, the count of configurable frequency domain resource units of the CSI-RS resource is greater than or equal to min {24, 22}. In this case, the terminal does not necessarily need to perform one or more of the following actions: determine a first frequency domain resource capable of receiving downlink transmission; determine the count of frequency domain resource units occupied by the first frequency domain resource; determine that the count of configurable frequency domain resource units of the CSI-RS is greater than or equal to min {24, 22}; not expect the count of configurable frequency domain resource units of the CSI-RS to be less than min {24, 22}.

[0096] In one embodiment, if the first frequency domain resource that the terminal can use to receive downlink transmission includes a downlink subband and a guard band, the terminal can determine a non-continuous frequency domain resource capable of receiving downlink transmission that includes the downlink subband and the guard band as the first frequency domain resource.

[0097] For example, the non-continuous frequency domain resource includes downlink subband #1, downlink subband #2, guard band #1, and guard band #2. Downlink subband #1 and guard band #1 connected to downlink subband #1, and downlink subband #2 and guard band #2 connected to downlink subband #2, can be determined as the first frequency domain resource capable of receiving downlink transmission. The second count is equal to the sum of the number of RBs contained in the downlink subband. Petition 870260001187, dated 07 / 01 / 2026, page 34 / 161 / 70 No. 1, guard band No. 1, downlink sub-band No. 2 and guard band No. 2, that is, 12+2+10+2=26. Therefore, the terminal determines that the count of configurable frequency domain resource units of the CSI-RS is greater than or equal to min {24, 26}, and / or does not expect the count of configurable frequency domain resource units of the CSI-RS resource to be less than min {24, 26}. where min {24, 26} is 24, then the terminal determines that the CSI-RS configurable frequency domain resource unit count is greater than or equal to min {24, 26}, and / or does not expect the CSI-RS resource configurable frequency domain resource unit count to be less than 24.

[0098] Alternatively, the terminal determines the CSI-RS resource according to a protocol agreement or network device configuration information and receives the CSI-RS according to the CSI-RS resource, wherein the relationship between the configurable frequency domain resource unit count of the CSI-RS resource and the minimum of the first count and the second count is agreed upon by the protocol or determined by the network device and does not necessarily require terminal participation, for example, the configurable frequency domain resource unit count of the CSI-RS resource is greater than or equal to min {24, 26}.In this case, the terminal does not necessarily need to perform one or more of the following actions: determine a first frequency domain resource capable of receiving downlink transmission; determine the count of frequency domain resource units occupied by the first frequency domain resource; determine that the CSI-RS configurable frequency domain resource unit count is greater than or equal to min {24, 26}; do not expect the CSI-RS configurable frequency domain resource unit count to be less than min {24, 26}.

[0099] In one modality, the second count is a multiple Petition 870260001187, dated 07 / 01 / 2026, page 35 / 161 / 70 whole of a first value; where the count of configured frequency domain resource units of the channel state information reference signal resource is greater than or equal to the second count.

[00100] In one embodiment, although the terminal does not expect the configurable frequency domain resource unit count of the CSI-RS resource to be less than the minimum between the first and second counts, and / or the frequency domain resource unit count of the CSI-RS resource configured by the network device for the terminal is not less than the minimum between the first and second counts, the frequency domain resource unit count of the CSI-RS resource configured by the network device for the terminal may be greater than or equal to the second count.

[00101] When the frequency domain resource unit count of the CSI-RS resource configured by the network device for the terminal is greater than the second count, to ensure that the CSIRS resource actually used to transmit the CSI-RS does not exceed the frequency domain range in which the terminal can receive the CSI-RS, the terminal can determine that the frequency domain resource unit count of the CSI-RS resource is equal to the second count, that is, the frequency domain resource unit count contained in the CSI-RS resource actually used to transmit the CSI-RS is equal to the second count.

[00102] Since the count of frequency domain resource units occupied by the CSI-RS resource needs to be a positive integer multiple of a first value, taking the frequency domain resource unit as an RB and the first value as 4 as an example, the count of RBs occupied by the CSI-RS resource needs to be equal to 4n, where n is a positive integer. Therefore, the terminal can determine that the second count is an integer multiple of the first value and / or the terminal does not expect the second count to be a value other than a multiple. Petition 870260001187, dated 07 / 01 / 2026, page 36 / 161 / 70 integer of the first value. Then, the second count is an integer multiple of the first value, for example, 4n, thus ensuring that the count of frequency domain resource units contained in the CSI-RS resource actually used to transmit the CSI-RS is a positive integer multiple of the first value, and that the CSI-RS resource actually used to transmit the CSI-RS does not exceed the frequency domain range in which the terminal can receive the CSI-RS.

[00103] For example, the second count is equal to 8, which is 2 times 4. The frequency domain resource unit count of the CSIRS resource configured by the network device for the terminal is 12, which is greater than 8. In this case, the terminal can determine that the frequency domain resource unit count contained in the CSI-RS resource actually used to transmit the CSI-RS is equal to 8.

[00104] Figure 6 is a schematic flowchart of another method for determining resources according to an embodiment of the present description. The method for determining resources shown in this embodiment can be performed by a terminal. As shown in Figure 6, the method for determining resources additionally includes:

[00105] Step S601: Determine a frequency domain resource unit count contained in the channel state information reference signal resource as a maximum value, among integer multiples of a first value, that is less than or equal to the second count; wherein the configured frequency domain resource unit count of the channel state information reference signal resource is greater than or equal to the second count.

[00106] In one embodiment, although the terminal does not expect the configurable frequency domain resource unit count of the CSI-RS resource to be less than the minimum between the first and second counts, and / or the frequency domain resource unit count of Petition 870260001187, dated 07 / 01 / 2026, page 37 / 161 / 70 The frequency of the CSI-RS resource configured by the network device for the terminal is not less than the minimum between the first and second counts; the frequency domain resource unit count of the CSIRS resource configured by the network device for the terminal may be greater than or equal to the second count.

[00107] When the frequency domain resource unit count of the CSI-RS resource configured by the network device for the terminal is greater than the second count, the terminal may determine the frequency domain resource unit count of the CSIRS resource as the maximum value, among the integer multiples of the first value, that is less than or equal to the second count; that is, the frequency domain resource unit count contained in the CSI-RS resource actually used to transmit the CSI-RS is the maximum value, among the integer multiples of the first value, that is less than or equal to the second count.

[00108] Since the count of frequency domain resource units occupied by the CSI-RS resource needs to be a positive integer multiple of the first value, taking the frequency domain resource unit as an RB and the first value as 4, the count of RBs occupied by the CSI-RS resource needs to be equal to 4n, where n is a positive integer.If the second count is a value other than an integer multiple of the first value, the terminal can determine the count of frequency domain resource units contained in the CSI-RS resource as the maximum value, among the integer multiples of the first value, that is less than or equal to the second count, thus ensuring that the count of frequency domain resource units contained in the CSI-RS resource actually used to transmit the CSI-RS is a positive integer multiple of the first value, and that the CSI-RS resource actually used to transmit the CSI-RS does not exceed the frequency domain range in which the terminal can receive the CSI-RS. Petition 870260001187, dated 07 / 01 / 2026, page 38 / 161 / 70

[00109] When the frequency domain resource unit count of the CSI-RS resource configured by the network device for the terminal is greater than the second count, and the second count is an integer multiple of the first value, the terminal can determine that the count of RBs occupied by the CSI-RS resource is equal to the second count.

[00110] When the frequency domain resource unit count of the CSI-RS resource configured by the network device for the terminal is greater than the second count, and the second count is not an integer multiple of the first value, the terminal can determine values ​​equal to integer multiples of the first value among the values ​​less than the second count, determine the maximum value among the values ​​equal to integer multiples of the first value (for example, 4), and then determine that the count of RBs occupied by the CSI-RS resource is equal to that maximum value.

[00111] For example, the second count is equal to 8, which is a positive integer multiple of 4. The frequency domain resource unit count of the CSI-RS resource configured by the network device for the terminal is 12, which is greater than 8. In this case, the terminal can determine that the frequency domain resource unit count of the CSI-RS resource is equal to 8.

[00112] For example, the second count is equal to 10, which is not a positive integer multiple of 4. The frequency domain resource unit count of the CSI-RS resource configured by the network device for the terminal is 12, which is greater than 10. In this case, the terminal can determine values ​​equal to 4n between values ​​less than 10, which are 4 and 8, determine the maximum value 8 between 4 and 8, and then determine that the count of RBs occupied by the CSI-RS resource is equal to 8.

[00113] Figure 7 is a schematic flowchart of another method for determining resources according to an embodiment of the present description. The method for determining resources shown in this embodiment Petition 870260001187, dated 07 / 01 / 2026, page 39 / 161 / 70, can be performed via a terminal. As shown in Figure 7, the method for determining the resources additionally includes:

[00114] Step S701: when the frequency domain resource unit count of the channel state information reference signal resource is greater than the second count, determine that the frequency domain resource unit count of the channel state information reference signal resource is equal to the second count.

[00115] In one embodiment, although the terminal does not expect the configurable frequency domain resource unit count of the CSI-RS resource to be less than the minimum between the first and second counts, and / or the frequency domain resource unit count of the CSI-RS resource configured by the network device for the terminal is not less than the minimum between the first and second counts, the frequency domain resource unit count of the CSI-RS resource configured by the network device for the terminal may be greater than or equal to the second count.

[00116] When the frequency domain resource unit count of the CSI-RS resource configured by the network device for the terminal is greater than the second count, the terminal can determine that the frequency domain resource unit count of the CSIRS resource is equal to the second count, thus ensuring that the CSI-RS can be sent by the network device and received by the terminal within the range of the first frequency domain resource capable of receiving downlink transmission, preventing the network device from sending the CSI-RS outside the range of the first frequency domain resource capable of receiving downlink transmission by the terminal, which the terminal will not be able to receive.

[00117] In one mode, the terminal can determine values ​​equal to integer multiples of the first value between values ​​less than or equal to Petition 870260001187, dated 07 / 01 / 2026, page 40 / 161 / 70 second count, determine the maximum value among the values ​​equal to integer multiples of the first value (e.g., 4) and determine that the CSI-RS configurable frequency domain resource unit count is greater than or equal to the minimum between the first count and that maximum value, and / or do not expect the CSI-RS resource configurable frequency domain resource unit count to be less than the minimum between the first count and that maximum value.

[00118] For example, the first value is equal to 4, the first count is 24, and the second count is 10. The terminal can determine values ​​equal to integer multiples of the first value between values ​​less than or equal to the second, counting them as 8 and 4, where 8 is the maximum value. Then, the terminal can determine that the CSI-RS configurable frequency domain feature unit count is greater than or equal to min {24, 8}, and / or does not expect the CSI-RS feature configurable frequency domain feature unit count to be less than min {24, 8}=8.

[00119] In one embodiment, the second count is greater than or equal to the first count, and the count of configurable frequency domain resource units of the CSI-RS resource is greater than or equal to the lesser value between the first count and a third count, wherein the third count is the count of frequency domain resource units occupied by the BWP where the first frequency domain resource capable of receiving downlink transmission is located. And / or the terminal does not expect the second count to be less than the first count, and does not expect the count of configurable frequency domain resource units of the CSI-RS resource to be less than the minimum between the first and third counts.When the frequency domain resource unit count of the CSI-RS resource configured by the network device for the terminal is greater than the third count, the terminal can determine that the frequency domain resource unit count of the CSI resource. (See EDITION 870260001187, dated 07 / 01 / 2026, page 41 / 161 / 70.) RS equals the second count.

[00120] For example, the minimum value of the configurable frequency domain resource unit count of the CSI-RS resource is min {first count, third count}, and the count of RBs occupied by the first frequency domain resource capable of receiving downlink transmission by the terminal is the second count. Since the third count is greater than or equal to the second count, under the condition that the second count is greater than or equal to the first count, it can be determined that the third count is greater than or equal to the first count, then the minimum value of the configurable frequency domain resource unit count of the CSI-RS resource can be the first count. And the third count is greater than or equal to the configurable frequency domain resource unit count of the CSI-RS resource.Therefore, it is possible to satisfy the minimum value of the configurable frequency domain resource unit count of the CSI-RS resource being min{first count, third count}, and the minimum value (first count) of the configurable frequency domain resource unit count of the CSI-RS resource being within the frequency domain resource unit count range (second count) occupied by the first frequency domain resource capable of receiving downlink transmission by the terminal. Thus, the network side can configure the corresponding CSI-RS resource based on the satisfaction of the above conditions, so that the frequency domain resource units configured for the CSI-RS resource are within the range of the first frequency domain resource, ensuring that the terminal receives the CSI-RS within the receiveable frequency domain range.

[00121] In one embodiment, the configurable frequency domain resource unit count of the CSI-RS resource is greater than or equal to the smaller of the first count and a third count, where the Petition 870260001187, dated 07 / 01 / 2026, page 42 / 161 / 70 The third count is the count of frequency domain resource units occupied by the BWP where the first frequency domain resource capable of receiving downlink transmission is located, and / or the count of frequency domain resource units occupied by the downlink BWP where the terminal is located. That is, the terminal does not expect the configurable frequency domain resource unit count of the CSI-RS resource to be less than the minimum between the first and third counts. When the frequency domain resource unit count of the CSI-RS resource configured by the network device for the terminal is greater than the second count, the terminal can determine that the frequency domain resource unit count of the CSI-RS resource is equal to the second count.The second count is determined based on the previous modalities, which will not be repeated here.

[00122] Figure 8 is a schematic flowchart of a method for determining resources according to an embodiment of the present description. The method for determining resources shown in this embodiment can be performed by a network device. The network device can communicate with a terminal. The network device includes, but is not limited to, base stations in communication systems such as 4G base stations, 5G base stations, 6G base stations, etc. The terminal includes, but is not limited to, a mobile phone, a tablet, a wearable device, a sensor, an Internet of Things device, and other communication devices.

[00123] As shown in Figure 8, the method for determining the resources may include the following steps: Step S801: Determine, based on a minimum of a first count and a second count, a minimum frequency domain resource unit count of a channel state information reference signal resource configured for a terminal. Petition 870260001187, dated 07 / 01 / 2026, page 43 / 161 / 70 where the second count is a count of frequency domain resource units occupied by a first frequency domain resource capable of receiving downlink transmission by the terminal.

[00124] In one embodiment, when configuring the CSI-RS resource for the terminal, the network device may first determine a first frequency domain resource available to the terminal to receive downlink transmission and determine the second count of frequency domain resource units occupied by the first frequency domain resource. Then, according to the minimum between the first and second count, the minimum frequency domain resource unit count of the CSI-RS resource configured for the terminal is determined.Thus, the frequency domain resource unit count of the CSI-RS resource configured by the network device for the terminal will not be less than (i.e., greater than or equal to) the minimum between the first count and the second count. Consequently, it is beneficial to ensure that the understanding of the CSI-RS resource by the network device and the terminal is consistent, in order to ensure the quality of subsequent communication between the network device and the terminal.

[00125] Correspondingly, the terminal can determine a first frequency domain resource capable of receiving downlink transmission and determine the count of frequency domain resource units occupied by the first frequency domain resource, for example, referred to as the second count. That is, the terminal may not expect the configurable frequency domain resource unit count of the CSI-RS resource to be less than the minimum between the first and second counts.

[00126] In one mode, the first count is determined based on a predefined rule or is configured by the network device. For example, when the frequency domain resource unit is an RB, the Petition 870260001187, dated 07 / 01 / 2026, page 44 / 161 / 70 first count may be 24.

[00127] For example, the network device determines that the frequency domain resource unit count occupied by the first frequency domain resource capable of receiving downlink transmission from the terminal is 10, that is, the second count is 10. Then, the minimum value of the frequency domain resource unit count of the CSI-RS resource configured by the network device for the terminal is min {24, 10}. where min {24, 10} is 10, then the minimum value of the frequency domain resource unit count of the CSI-RS resource configured for the terminal is 10.

[00128] In one embodiment, the first frequency domain resource capable of being used to receive downlink transmission includes at least one of: a downlink subband; a guard band.

[00129] In one embodiment, the downlink subband includes at least one of: a frequency domain resource, configured in a downlink slot, that is not an uplink subband; a frequency domain resource, configured in a downlink slot, that is not an uplink subband and a guard band; a frequency domain resource, configured in a flexible slot, that is not an uplink subband; a frequency domain resource, configured in a flexible slot, that is not an uplink subband and a guard band; a downlink subband configured in an uplink slot; a downlink subband configured in a flexible slot.

[00130] For example, the network device configures an uplink sub-band for the terminal in a downlink slot. The frequency domain resources in the frequency domain resources corresponding to the downlink slot, which are not from the sub-band Petition 870260001187, dated 07 / 01 / 2026, page 45 / 161 / 70 of uplink, may be referred to as downlink sub-band, and the terminal may receive downlink transmission in the downlink sub-band. In this case, the first frequency domain resource capable of being used to receive downlink transmission includes frequency domain resources in the frequency domain resources corresponding to the downlink slot, except in the uplink sub-band.

[00131] For example, the network device configures an uplink subband and a guard band for the terminal in a downlink slot. The frequency domain resources in the frequency domain resources corresponding to the downlink slot, other than the uplink subband, and the guard band can be referred to as a downlink subband, and the terminal can receive downlink transmission in the downlink subband. In this case, the first frequency domain resource capable of being used to receive downlink transmission includes frequency domain resources in the frequency domain resources corresponding to the downlink slot, except for the uplink subband and the guard band.

[00132] For example, the network device configures an uplink subband for the terminal in a flexible slot. The frequency domain resources in the frequency domain resources corresponding to the flexible slot, other than the uplink subband, can be referred to as a downlink subband, and the terminal can receive downlink transmissions in the downlink subband. In this case, the first frequency domain resource capable of being used to receive downlink transmission includes frequency domain resources in the frequency domain resources corresponding to the flexible slot, except for the uplink subband. Petition 870260001187, dated 07 / 01 / 2026, page 46 / 161 / 70 ascendant.

[00133] For example, the network device configures an uplink subband and a guard band for the terminal in a flexible slot. The frequency domain resources in the frequency domain resources corresponding to the flexible slot, other than the uplink subband and the guard band, can be referred to as a downlink subband, and the terminal can receive downlink transmission in the downlink subband. In this case, the first frequency domain resource capable of being used to receive downlink transmission includes frequency domain resources in the frequency domain resources corresponding to the flexible slot, except for the uplink subband and the guard band.

[00134] For example, the network device configures a downlink subband for the terminal in an uplink slot. The terminal can receive downlink transmission in the downlink subband. In this case, the first frequency domain resource capable of being used to receive the downlink transmission includes the downlink subband in the uplink slot.

[00135] For example, the network device configures a downlink subband for the terminal in a flexible slot. The terminal can receive downlink transmission in the downlink subband. In this case, the first frequency domain resource capable of being used to receive downlink transmission includes the downlink subband in the flexible slot.

[00136] In one embodiment, the first frequency domain resource capable of receiving downlink transmission includes: continuous frequency domain resources capable of receiving downlink transmission, wherein the channel state information reference signal resource includes frequency domain resource units. Petition 870260001187, dated 07 / 01 / 2026, page 47 / 161 / 70 continuous.

[00137] That is, when the CSI-RS resource includes continuous frequency domain resource units, the first frequency domain resource capable of receiving downlink transmission may include continuous frequency domain resources capable of receiving downlink transmission.

[00138] In one embodiment, if the first frequency domain resource that the terminal can use to receive downlink transmission includes a downlink subband, the network device can determine the downlink subband in which the initial frequency domain resource unit is located as the first frequency domain resource.

[00139] For example, if there is only one downlink subband in the enabled BWP, the network device can determine that downlink subband as the first frequency domain resource. Based on the mode shown in Figure 2, there are two downlink subbands in the enabled BWP, and the two downlink subbands are discontinuous. So, when the CSI-RS resource includes continuous frequency domain resource units, the first frequency domain resource capable of receiving downlink transmission can be either of these two downlink subbands.Therefore, when there are multiple continuous frequency domain resources capable of receiving downlink transmission, considering that the CSI-RS resource can only include continuous frequency domain resources, the CSI-RS resource can only be transmitted on one of the continuous frequency domain resources, and the network device needs to determine one continuous frequency domain resource as the first frequency domain resource.

[00140] In one embodiment, the first domain resource of Petition 870260001187, dated 07 / 01 / 2026, page 48 / 161 / 70 frequency capable of receiving downlink transmission includes: a continuous frequency domain resource that is capable of receiving downlink transmission based on an initial frequency domain resource unit of the channel state information reference signal resource.

[00141] The network device can send CSI-RS resource configuration information to the terminal, and the terminal can determine the CSI-RS resource based on the configuration information. For example, the configuration information includes at least one of: an initial frequency domain resource unit of the CSI-RS resource, or a count of continuous frequency domain resource units.

[00142] The network device can determine, among multiple continuous frequency domain resources capable of receiving downlink transmission by the terminal, the continuous frequency domain resource that is capable of receiving downlink transmission based on the initial frequency domain resource unit as the first frequency domain resource.

[00143] By way of example, a count of frequency domain resource units by which the initial frequency domain resource unit of the CSI-RS resource is shifted from an initial frequency domain resource unit of a common CRB resource block no. 0 may be a positive integer multiple of a first value.

[00144] As shown in Figure 4, two downlink sub-bands can be determined in the enabled BWP, which are downlink sub-band #1 and downlink sub-band #2. The network device determines, according to the CSI-RS resource configuration information sent to the terminal, that the initial frequency domain resource unit of the CSI-RS resource is in downlink sub-band #1, therefore, downlink sub-band #1 can be Petition 870260001187, dated 07 / 01 / 2026, page 49 / 161 / 70, determined as the first frequency domain resource capable of receiving downlink transmission.

[00145] Taking as an example the frequency domain resource unit, including RBs, for example, in Figure 4, downlink sub-band #1 includes 12 RBs and downlink sub-band #2 includes 10 RBs. If downlink sub-band #1 is used as the first frequency domain resource capable of receiving downlink transmission based on the analysis above, the second count is 12, equal to the number of RBs contained in downlink sub-band #1, that is, 12 RBs. Then, the network device can determine that the minimum value of the frequency domain resource unit count of the CSIRS resource configured for the terminal is min {24, 12}. where min {24, 12} is 12, then the minimum value of the frequency domain resource unit count of the CSI-RS resource configured for the terminal is 12.

[00146] In one embodiment, if the first frequency domain resource that the terminal can use to receive downlink transmission includes a downlink subband and a guard band, the network device can determine the downlink subband in which the initial frequency domain resource unit is located and the guard band connected to the downlink subband as the first frequency domain resource.

[00147] For example, when the initial frequency domain resource unit of the CSI-RS resource is in downlink subband #1 or guard band #1, downlink subband #1 and guard band #1 connected to downlink subband #1 can be determined as the first frequency domain resource capable of receiving downlink transmission. The second count is equal to the sum of the number of RBs contained in downlink subband #1 and guard band #1, i.e., 12 ÷ 2 = 14. Then, the network device Petition 870260001187, dated 07 / 01 / 2026, page 50 / 161 / 70, can determine that the minimum value of the frequency domain resource unit count of the CSI-RS resource configured for the terminal is min {24, 14}. where min {24, 14} is 14, then the minimum value of the frequency domain resource unit count of the CSI-RS resource configured for the terminal is 14.

[00148] In one embodiment, the first frequency domain resource capable of receiving downlink transmission includes: a continuous frequency domain resource, among all continuous frequency domain resources capable of receiving downlink transmission, that occupies a lower frequency domain unit count.

[00149] When the terminal has multiple continuous frequency domain resources capable of receiving downlink transmission, the network device can determine the frequency domain unit count occupied by each continuous frequency domain resource and use the continuous frequency domain resource that occupies the lowest frequency domain unit count as the first frequency domain resource.

[00150] In one embodiment, if the first frequency domain resource that the terminal can use to receive downlink transmission includes a downlink subband, the network device can determine the frequency domain unit count occupied by each downlink subband and determine the downlink subband that occupies the lowest frequency domain unit count as the first frequency domain resource.

[00151] As shown in Figure 5, two downlink sub-bands can be determined in the enabled BWP, which are downlink sub-band #1 and downlink sub-band #2. The network device determines this according to the configuration information. Petition 870260001187, dated 07 / 01 / 2026, page 51 / 161 / 70 of the CSI-RS resource sent to the terminal, that the initial frequency domain resource unit of the CSI-RS resource is in downlink sub-band #2, therefore, downlink sub-band #2 can be determined as the first frequency domain resource capable of receiving downlink transmission.

[00152] Taking the frequency domain resource unit, including RBs, as an example, in Figure 5, downlink sub-band #1 includes 12 RBs and downlink sub-band #2 includes 10 RBs. Therefore, between the two downlink sub-bands, downlink sub-band #2 occupies the smaller number of RBs. Therefore, downlink sub-band #2 can be used as the first frequency domain resource capable of receiving downlink transmission, so the second count is 10. Thus, the network device can determine that the minimum value of the frequency domain resource unit count of the CSI-RS resource configured for the terminal is min {24, 10}. where min {24, 10} is 10, then the minimum value of the frequency domain resource unit count of the CSI-RS resource configured for the terminal is 10.

[00153] In one embodiment, if the first frequency domain resource that the terminal can use to receive downlink transmission includes a downlink subband and a guard band, the network device can determine the downlink subband that occupies the lowest frequency domain unit count and the guard band connected to the downlink subband as the first frequency domain resource.

[00154] For example, between the count of frequency domain units occupied by downlink subband #1 and guard band #1 connected to downlink subband #1 and the count of frequency domain units occupied by the subband of Petition 870260001187, dated 07 / 01 / 2026, page 52 / 161 / 70 downlink subband #2 and guard band #2 connected to downlink subband #2, the count of frequency domain units occupied by downlink subband #2 and guard band #2 connected to downlink subband #2 is the lowest. Downlink subband #2 and guard band #2 connected to downlink subband #2 can be determined as the first frequency domain resource capable of receiving downlink transmission. The second count is equal to the sum of the number of RBs contained in the downlink sub-band #2 and the guard band #2, that is, 10 ÷ 2 = 12. Therefore, the network device can determine that the minimum value of the frequency domain resource unit count of the CSIRS resource configured for the terminal is min {24, 12}.where min {24, 12} is 12, then the minimum value of the frequency domain resource unit count of the CSI-RS resource configured for the terminal is 12.

[00155] It should be noted that the method of determining a continuous frequency domain resource as the first frequency domain resource among multiple continuous frequency domain resources capable of receiving downlink transmission is not limited to the method described in the above modalities.For example, the first frequency domain resource capable of receiving downlink transmission includes: a continuous frequency domain resource, among all continuous frequency domain resources capable of receiving downlink transmission, that occupies a higher frequency domain unit count; for example, the first frequency domain resource capable of receiving downlink transmission includes: a continuous frequency domain resource, among all continuous frequency domain resources capable of receiving downlink transmission, that is indicated by the network device (for example, the network device may indicate a frequency domain resource identifier, a range of... Petition 870260001187, dated 07 / 01 / 2026, page 53 / 161 / 70 frequency domain, etc.); for example, the first frequency domain resource capable of receiving downlink transmission includes: a continuous frequency domain resource, among all continuous frequency domain resources capable of receiving downlink transmission, where the count of occupied frequency domain units is an integer multiple of a first value (for example, 4).If multiple conditions exist, other conditions (such as identifier, initial frequency domain resource unit) can be combined to determine, for example, the continuous frequency domain resource corresponding to the smallest identifier that satisfies the above condition as the first frequency domain resource capable of receiving downlink transmission; for example, the first frequency domain resource capable of receiving downlink transmission includes: a continuous frequency domain resource, among all continuous frequency domain resources capable of receiving downlink transmission, whose identifier is a predefined identifier (e.g., the smallest identifier or the largest identifier).

[00156] In one embodiment, the first frequency domain resource capable of receiving downlink transmission includes a non-continuous frequency domain resource capable of receiving downlink transmission, wherein the channel state information reference signal resource may include non-continuous frequency domain resource units.

[00157] That is, where the CSI-RS resource may include non-continuous frequency-domain resource units, the first frequency-domain resource capable of receiving downlink transmission may include a non-continuous frequency-domain resource capable of receiving downlink transmission. It should be noted that this does not mean that the first frequency-domain resource cannot include Petition 870260001187, dated 07 / 01 / 2026, page 54 / 161 / 70 a continuous frequency domain resource capable of receiving downlink transmission, but rather that the first frequency domain resource may include both a continuous frequency domain resource capable of receiving downlink transmission and a non-continuous frequency domain resource capable of receiving downlink transmission.

[00158] In one embodiment, if the first frequency domain resource that the terminal can use to receive downlink transmission includes a downlink subband, the network device can determine the count of frequency domain units occupied by all downlink subbands as the first frequency domain resource.

[00159] For example, if there is only one downlink subband in the enabled BWP, the network device can determine that downlink subband as the first frequency domain resource. Based on the mode shown in Figure 2, there are two downlink subbands in the enabled BWP, and the two downlink subbands are discontinuous. So, when the CSI-RS resource includes non-continuous frequency domain resource units, the first frequency domain resource capable of receiving downlink transmission can be these two downlink subbands.

[00160] Using Figure 5 as an example, the terminal can determine two downlink sub-bands, which are downlink sub-band #1 and downlink sub-band #2. The terminal can determine downlink sub-band #1 and downlink sub-band #2 as the first frequency domain resource capable of receiving downlink transmission.

[00161] Taking as an example the frequency domain resource unit, including RBs, for example, in Figure 5, the link sub-band Petition 870260001187, dated 07 / 01 / 2026, page 55 / 161 / 70 descending link sub-band #1 includes 12 RBs and descending link sub-band #2 includes 10 RBs. The total number of RBs contained in the two descending link sub-bands is 22, therefore the second count is 22. Thus, the network device can determine that the minimum value of the frequency domain resource unit count of the CSI-RS resource configured for the terminal is min{24, 22}. where min{24, 22} is 22, therefore the minimum value of the frequency domain resource unit count of the CSI-RS resource configured for the terminal is 22.

[00162] In one embodiment, if the first frequency domain resource that the terminal can use to receive downlink transmission includes a downlink subband and a guard band, the network device can determine a non-continuous frequency domain resource capable of receiving downlink transmission that includes the downlink subband and the guard band as the first frequency domain resource.

[00163] For example, the non-continuous frequency domain resource includes downlink subband #1, downlink subband #2, guard band #1, and guard band #2. Downlink subband #1 and guard band #1 connected to downlink subband #1, and downlink subband #2 and guard band #2 connected to downlink subband #2, can be determined as the first frequency domain resource capable of receiving downlink transmission. The second count is equal to the sum of the number of RBs contained in downlink sub-band #1, guard band #1, downlink sub-band #2, and guard band #2, that is, 12+2+10+2=26. Therefore, the network device can determine that the minimum value of the frequency domain resource unit count of the CSI-RS resource configured for the terminal is min {24, 26}.where min {24, 26} is 24, then the minimum value of the count is... Petition 870260001187, dated 07 / 01 / 2026, page 56 / 161 / 70 frequency domain resource units of the CSI-RS resource configured for the terminal is 24.

[00164] In one embodiment, the method for determining features additionally includes: determining that the second count is an integer multiple of a first value; wherein the configured frequency domain feature unit count of the channel state information reference signal feature is greater than or equal to the second count.

[00165] In one embodiment, although the frequency domain resource unit count of the CSI-RS resource configured by the network device for the terminal is not less than the minimum between the first count and the second count, the frequency domain resource unit count of the CSI-RS resource configured by the network device for the terminal may be greater than or equal to the second count.

[00166] When the frequency domain resource unit count of the CSI-RS resource configured by the network device for the terminal is greater than the second count, to ensure that the CSIRS resource actually used to transmit the CSI-RS does not exceed the frequency domain range in which the terminal can receive the CSI-RS, the terminal will determine that the frequency domain resource unit count of the CSI-RS resource is equal to the second count, that is, the frequency domain resource unit count contained in the CSI-RS resource actually used to transmit the CSI-RS is equal to the second count.

[00167] Since the count of frequency domain resource units occupied by the CSI-RS resource needs to be a positive integer multiple of the first value, taking the frequency domain resource unit as an RB and the first value as 4 as an example, the count of RBs occupied by the CSI-RS resource needs to be equal to 4n, where n is a positive integer. Therefore, the terminal can determine that the second count is an integer multiple of the first value and / or the terminal does not expect Petition 870260001187, dated 07 / 01 / 2026, page 57 / 161 / 70 that the second count is a value other than an integer multiple of the first value. Therefore, the second count is an integer multiple of the first value, for example, 4n. Then, the network device also needs to determine if the second count is an integer multiple of the first value, thus ensuring that the terminal and the network device have a consistent understanding of the frequency domain resource unit count contained in the CSI-RS resource actually used to transmit the CSIRS, which is a positive integer multiple of the first value, and that the CSIRS resource actually used to transmit the CSI-RS does not exceed the frequency domain range in which the terminal can receive the CSI-RS.

[00168] For example, the second count is equal to 8, which is 2 times 4. The frequency domain resource unit count of the CSIRS resource configured by the network device for the terminal is 12, which is greater than 8. In this case, the terminal can determine that the frequency domain resource unit count contained in the CSI-RS resource actually used to transmit the CSI-RS is equal to 8, and the network device will also determine that the frequency domain resource unit count contained in the CSI-RS resource actually used to transmit the CSI-RS is equal to 8.

[00169] In one embodiment, the method for determining resources additionally includes: determining a count of frequency domain resource units contained in the channel state information reference signal resource as a maximum value, among integer multiples of a first value, that is less than or equal to the second count; wherein the configured frequency domain resource unit count of the channel state information reference signal resource is not equal to an integer multiple of the first value.

[00170] In one embodiment, although the frequency domain resource unit count of the CSI-RS resource configured by Petition 870260001187, dated 07 / 01 / 2026, page 58 / 161 / 70 network device for the terminal is not less than the minimum between the first count and the second count, the frequency domain resource unit count of the CSI-RS resource configured by the network device for the terminal may be greater than or equal to the second count.

[00171] When the frequency domain resource unit count of the CSI-RS resource configured by the network device for the terminal is greater than the second count, the terminal may determine the frequency domain resource unit count of the CSIRS resource as the maximum value, among the integer multiples of the first value, that is less than or equal to the second count; that is, the frequency domain resource unit count contained in the CSI-RS resource actually used to transmit the CSI-RS is the maximum value, among the integer multiples of the first value, that is less than or equal to the second count.

[00172] Since the count of frequency domain resource units occupied by the CSI-RS resource needs to be a positive integer multiple of the first value, taking the frequency domain resource unit as an RB and the first value as 4, the count of RBs occupied by the CSI-RS resource needs to be equal to 4n, where n is a positive integer.If the second count is a value other than an integer multiple of the first value, the terminal device may determine the count of frequency domain resource units contained in the CSI-RS resource as the maximum value, among the integer multiples of the first value, that is less than or equal to the second count, thus ensuring that the count of frequency domain resource units contained in the CSI-RS resource actually used to transmit the CSI-RS is a positive integer multiple of the first value, and that the CSI-RS resource actually used to transmit the CSI-RS does not exceed the frequency domain range in which the terminal may receive the CSI-RS.

[00173] When counting domain resource units of Petition 870260001187, dated 07 / 01 / 2026, page 59 / 161 / 70 If the frequency of the CSI-RS resource configured by the network device for the terminal is greater than the second count, and the second count is an integer multiple of the first value, the terminal can determine that the count of RBs occupied by the CSI-RS resource is equal to the second count.

[00174] When the frequency domain resource unit count of the CSI-RS resource configured by the network device for the terminal is greater than the second count, and the second count is not an integer multiple of the first value, the terminal can determine values ​​equal to integer multiples of the first value among the values ​​less than the second count, determine the maximum value among the values ​​equal to integer multiples of the first value (for example, 4), and then determine that the count of RBs occupied by the CSI-RS resource is equal to this maximum value. The network device can also determine that the count of RBs occupied by the CSI-RS resource is equal to this maximum value, thus ensuring that the terminal and the network device have a consistent understanding of the frequency domain resource unit count contained in the CSI-RS resource actually used to transmit the CSI-RS, which is this maximum value.

[00175] For example, the second count is equal to 8, which is a positive integer multiple of 4. The frequency domain resource unit count of the CSI-RS resource configured by the network device for the terminal is 12, which is greater than 8. In this case, the terminal can determine that the frequency domain resource unit count of the CSIRS resource is equal to 8, and the network device can also determine that the frequency domain resource unit count of the CSIRS resource is equal to 8.

[00176] For example, the second count equals 10, which is not a positive integer multiple of 4. The frequency domain resource unit count of the CSI-RS resource configured by the network device for the Petition 870260001187, dated 07 / 01 / 2026, page 60 / 161 / 70 terminal is 12, which is greater than 10. In this case, the terminal can determine values ​​equal to 4n between values ​​less than 10, which are 4 and 8, determine the maximum value 8 between 4 and 8, and then determine that the count of RBs occupied by the CSI-RS resource is equal to 8. The network device can also determine that the frequency domain resource unit count of the CSI-RS resource is equal to 8.

[00177] In one embodiment, the method for determining features additionally includes: when the frequency domain feature unit count of the channel state information reference signal feature is greater than the second count, determine that the frequency domain feature unit count of the channel state information reference signal feature is equal to the second count.

[00178] In one embodiment, although the frequency domain resource unit count of the CSI-RS resource configured by the network device for the terminal is not less than the minimum between the first count and the second count, the frequency domain resource unit count of the CSI-RS resource configured by the network device for the terminal may be greater than or equal to the second count.

[00179] When the frequency domain resource unit count of the CSI-RS resource configured by the network device for the terminal is greater than the second count, the terminal can determine that the frequency domain resource unit count of the CSIRS resource is equal to the second count, and the network device can also determine that the frequency domain resource unit count of the CSI-RS resource is equal to the second count, thus ensuring that the network device can send the CSI-RS to the terminal within the range of the first frequency domain resource capable of receiving downlink transmission, so as to prevent the network device from sending the CSIRS outside the range of the first frequency domain resource capable of Petition 870260001187, dated 07 / 01 / 2026, page 61 / 161 / 70 to receive downlink transmission by the terminal, which the terminal will not be able to receive.

[00180] In one embodiment, the network device can determine values ​​equal to integer multiples of the first value between values ​​less than or equal to the second count, determine the maximum value between values ​​equal to integer multiples of the first value (for example, 4), and determine that the count of configurable frequency domain resource units of the CSI-RS resource is not less than the minimum between the first count and that maximum value.

[00181] For example, the first value is equal to 4, the first count is 24, and the second count is 10. The network device can determine values ​​equal to integer multiples of the first value between values ​​less than or equal to the second, counting them as 8 and 4, where 8 is the maximum value. Then, the network device can determine that the count of configurable frequency domain resource units of the CSI-RS resource is not less than min {24, 8}=8.

[00182] In one embodiment, the second count is greater than or equal to the first count, and the configurable frequency domain resource unit count of the CSI-RS resource is greater than or equal to the smaller of the first count and a third count, wherein the third count is the frequency domain resource unit count occupied by the BWP where the first frequency domain resource capable of receiving downlink transmission is located. When the frequency domain resource unit count of the CSIRS resource configured by the network device for the terminal is greater than the second count, the terminal may determine that the frequency domain resource unit count of the CSI-RS resource is equal to the second count.

[00183] For example, the minimum value of the unit count of Petition 870260001187, dated 07 / 01 / 2026, page 62 / 161 / 70, configurable frequency domain resource of the CSI-RS resource is min {first count, third count}. Since the third count is greater than or equal to the first, the minimum value of the configurable frequency domain resource unit count of the CSI-RS resource can be the first count. And the third count is greater than or equal to the configurable frequency domain resource unit count of the CSIRS resource.Therefore, it is possible to satisfy the minimum value of the configurable frequency domain resource unit count of the CSIRS resource being min {first count, third count}, and the minimum value (first count) of the configurable frequency domain resource unit count of the CSI-RS resource being within the frequency domain resource unit count range (second count) occupied by the first frequency domain resource capable of receiving downlink transmission by the terminal. The situation where the configurable frequency domain resource unit count of the CSI-RS resource is greater than the second count will not occur, ensuring that the terminal receives the CSI-RS within the receiveable frequency domain range.

[00184] In one embodiment, the configurable frequency domain resource unit count of the CSI-RS resource is greater than or equal to the lesser of the first count and a third count, wherein the third count is the frequency domain resource unit count occupied by the BWP in which the first frequency domain resource capable of receiving downlink transmission is located. When the frequency domain resource unit count of the CSI-RS resource configured by the network device for the terminal is greater than the second count, the terminal may determine that the frequency domain resource unit count of the CSI-RS resource is equal to the second count. Petition 870260001187, dated 07 / 01 / 2026, page 63 / 161 / 70
