[0049] In some embodiments, the technical solution of the present disclosure can be applied to the Open RAN architecture. In this case, the interfaces between or within the access network devices involved in the embodiments of the present disclosure can be transformed into internal interfaces of the Open RAN, and the processes and information interactions between these internal interfaces can be implemented through software or programs.

[0050] In some embodiments, the access network device can be composed of a centralized unit (CU) and a distributed unit (DU), where the CU can also be called a control unit. The CU-DU structure can be used to split the protocol layer of the access network device, with the functions of some protocol layers centrally controlled by the CU, and the functions of the remaining part or all of the protocol layers distributed in the DU, which is centrally controlled by the CU, but is not limited to this.

[0051] In some embodiments, a core network device may be a single device comprising one or more network elements, or may be a plurality of devices or device groups, each comprising all or part of one or more network elements. A network element may be virtual or physical. The core network may, for example, comprise at least one of an Evolved Packet Core (EPC), a 5G Core Network (5GCN), or a Next Generation Core (NGC).

[0052] It can be understood that the communication system described in the embodiment of the present disclosure is for the purpose of more clearly illustrating the technical solution of the embodiment of the present disclosure, and does not constitute a limitation on the technical solution proposed in the embodiment of the present disclosure. Ordinary technicians in this field can know that with the evolution of the system architecture and the emergence of new business scenarios, the technical solution proposed in the embodiment of the present disclosure is also applicable to similar technical problems.

[0053] The following embodiments of the present disclosure may be applied to the communication system 100 shown in Figure 1, or a portion thereof, but are not limited thereto. The entities shown in Figure 1 are illustrative only. The communication system may include all or a portion of the entities shown in Figure 1, or may include other entities outside of Figure 1. The number and configuration of the entities may be arbitrary. The connection relationships between the entities are illustrative only. The entities may be connected or disconnected, and the connection may be in any manner, including direct or indirect, wired or wireless.

[0054] The embodiments of the present disclosure can be applied to Long Term Evolution (LTE), LTE-Advanced (LTE-A), LTE-Beyond (LTE-B), SUPER 3G, IMT-Advanced, 4th generation mobile communication system (4G), 5th generation mobile communication system (5G), 5G new radio (NR), future radio access (FRA), new radio access technology (RAT), new radio (NR), new radio access (NX), future generation radio access (FX), Global System for Mobile communications (GSM (registered trademark)), CDMA2000, Ultra Mobile Broadband (UMB), IEEE 802.11 (Wi-Fi (registered trademark)), IEEE 802.16 (WiMAX (registered trademark)), IEEE 802.20, Ultra-WideBand (UWB), Bluetooth (registered trademark), Public Land Mobile Network (PLMN) networks, Device-to-Device (D2D) systems, Machine-to-Machine (M2M) systems, Internet of Things (IoT) systems, Vehicle-to-Everything (V2X), systems utilizing other communication methods, and next-generation systems based on and extending these methods.

[0055] Optionally, discrete frequency domain resource allocation, namely Resource Allocation Type 0 (RA Type 0), can be used. Specifically, a bitmap can be used to indicate the allocated resource blocks (RBs), with one bit corresponding to one resource block group (RBG). An RBG is a collection of contiguous virtual resource blocks (VRBs), whose size is determined by the higher-level parameter rbg-Size and the bandwidth part (BWP).

[0056] Optionally, the granularity of a BWP may be smaller than the granularity of an RBG. The granularity of a BWP may also be referred to as the size of the BWP. The granularity of a BWP represents the number or number of resource blocks (RBs) contained in the BWP, and the granularity of an RBG represents the number or number of RBs contained in the RBG.

[0057] Optionally, the size of BWP may affect the determination of the frequency domain resources occupied by the channel. However, in the related art, when transmitting the channel, the impact of the size of BWP on the number of frequency domain resources occupied by the channel is not considered. Therefore, the related art cannot effectively determine the number of frequency domain resources occupied by the channel transmission, which may affect the effective transmission of the channel.

[0058] Optionally, the granularity may also be referred to as particle size, size, etc., without limitation.

[0059] Optionally, quantity and number have the same meaning.

[0060] FIG2A is an interactive diagram of a channel transmission method according to an embodiment of the present disclosure. As shown in FIG2A , the embodiment of the present disclosure relates to a channel transmission method, which can be used in a communication system 100. The method includes:

[0061] Step S2101: The terminal determines the number of frequency domain resources occupied by a first channel transmission according to a first granularity of a partial bandwidth BWP.

[0062] The first granularity represents the number of resource blocks (RBs) included in a BWP. The first granularity can be referred to as the size of a BWP. The first granularity is, for example, 2, which means that the number of RBs included in a BWP is 2, and there is no limitation on this.

[0063] In some embodiments, the first channel may be, for example, a physical uplink shared channel PUSCH or a physical downlink shared channel PDSCH, thereby effectively supporting the determination of the number of frequency domain resources occupied by PUSCH and / or PDSCH transmissions.

[0064] The number of frequency domain resources may refer to the number of RBs occupied by the first channel transmission.

[0065] In some embodiments, the network device may configure a first granularity of the BWP for the terminal, and the terminal may determine the number of frequency domain resources occupied by the first channel transmission according to the first granularity of the BWP.

[0066] For example, the network device may not configure the parameters related to the RBG granularity, but may configure the first granularity of the BWP. The terminal may directly determine the number of frequency domain resources occupied by the first channel transmission with reference to the first granularity of the BWP.

[0067] In some embodiments, the terminal may determine the number of frequency domain resources occupied by the first channel transmission with reference to the first granularity of the BWP. For example, the terminal may determine the number of frequency domain resources occupied by the first channel transmission with reference to the first granularity of the BWP and the mapping relationship between the first granularity of the BWP and the number of frequency domain resources occupied by the first channel transmission. Alternatively, the terminal may directly reference the first granularity of the BWP to select the number of frequency domain resources occupied by the first channel transmission; alternatively, the terminal may directly use the first granularity of the BWP as the number of frequency domain resources occupied by the first channel transmission; alternatively, the terminal may also reference the first granularity of the BWP to determine the number of frequency domain resources occupied by the first channel transmission based on any other possible method, without limitation.

[0068] In some embodiments, based on certain conditions, the terminal directly uses the first granularity of the BWP as the number of frequency domain resources occupied by the first channel transmission. The condition is that the first granularity of the BWP is less than or equal to a certain threshold. For example, the threshold is 2 RBs or 4 RBs. Alternatively, the threshold is determined based on the discrete resource allocation parameter rbg-Size configured by the base station. For example, when the base station is configured with rbg-size or with the rbg-Size value config2, the threshold is 4 RBs; otherwise, the threshold is 2 RBs.

[0069] In some embodiments, the terminal may determine the second granularity of the RBG according to the first granularity of the BWP, and determine the number of frequency domain resources occupied by the first channel transmission according to the second granularity of the RBG.

[0070] The second granularity of the RBG may refer to the redefined granularity of the RBG. The second granularity indicates the number of RBs contained in the RBG. The second granularity may also be referred to as the size of the RBG. For example, the second granularity may be the first number, indicating that the number of RBs contained in the RBG is the first number, without limitation.

[0071] In some embodiments, one or more RBGs may be partitioned within a BWP. The resulting RBGs may contain multiple RBs. The number of RBs contained in an RBG may be represented by a reference RBG granularity. The terminal may determine the reference RBG granularity based on the gNB configuration parameters configuration type 1 / 2, BWP size, and a protocol-preset table.

[0072] In some embodiments, the terminal may determine the second granularity of one or more RBGs based on the first granularity of the BWP and the reference granularity of the RBG, and determine the number of frequency domain resources occupied by the first channel transmission based on the second granularity of the one or more RBGs.

[0073] Therefore, the flexibility of determining the number of frequency domain resources occupied by the first channel transmission can be effectively improved, and the communication scenario with flexible BWP configuration can be effectively applied.

[0074] In some embodiments, the network device may also send configuration signaling to the terminal, and the terminal may determine the reference granularity of the RBG based on the configuration signaling (for example, based on the field (rbg-size) in the configuration signaling) and the protocol preset parameters (that is, the reference granularity of the RBG may be understood as the granularity of the RBG predefined by the protocol, and / or the granularity of the configured RBG). Then, the terminal may compare the first granularity of the BWP with the size of the reference granularity of the RBG, and determine the second granularity of one or more RBGs based on the comparison result.

[0075] In some embodiments, the terminal may determine the second granularity of the RBG based on a first relationship between the first granularity of the BWP and the reference granularity of the RBG, where the reference granularity of the RBG is the granularity of the RBG determined based on a preset protocol parameter and / or configuration signaling, and based on the first relationship. This allows accurate determination of the second granularity of the RBG to support effective determination of the number of frequency domain resources occupied by the first channel transmission.

[0076] The first relationship is used to describe the size comparison relationship between the first granularity of the BWP and the reference granularity of the RBG.

[0077] In some embodiments, the first relationship includes: the first granularity of the BWP is greater than or equal to the reference granularity of the RBG, or the first granularity of the BWP is smaller than the reference granularity of the RBG.

[0078] That is, the terminal can flexibly determine the second granularity of the RBG by referring to the size comparison relationship between the first granularity of the BWP and the reference granularity of the RBG, so as to support effective determination of the number of frequency domain resources occupied by the first channel transmission.

[0079] In some embodiments, the first granularity of the BWP is greater than or equal to the reference granularity of the RBG, and the second granularity of the RBG is determined based on the reference granularity of the RBG, thereby effectively determining the second granularity of the RBG.

[0080] That is to say, if the first granularity of the BWP is greater than or equal to the reference granularity of the RBG, it means that the RBG can be divided among the multiple RBs contained in the BWP based on the reference granularity of the RBG. For example, one or more RBGs can be obtained by starting from the RB with the lowest frequency in the BWP and dividing it with the reference granularity of the RBG.

[0081] In some embodiments, if the first granularity of the BWP is smaller than the reference granularity of the RBG, the terminal may determine the second granularity of the RBG based on the first granularity of the BWP, thereby effectively determining the second granularity of the RBG.

[0082] That is, if the first granularity of the BWP is smaller than the reference granularity of the RBG, the reference granularity of the RBG may not be suitable for dividing the RBG within the BWP. In this case, the terminal may redefine the second granularity of the RBG.

[0083] In some embodiments, if the first granularity of the BWP is smaller than the reference granularity of the RBG, the terminal may use the first granularity of the BWP as the second granularity of the RBG. In other words, if the first granularity of the BWP is smaller than the reference granularity of the RBG, the terminal may directly use the first granularity of the BWP as the second granularity of the redefined RBG.

[0084] In some embodiments, if the first granularity of the BWP is smaller than the reference granularity of the RBG, the first granularity of the BWP is equal to the redefined second granularity of the RBG. In this case, when the BWP is divided into RBGs, the BWP may contain one RBG.

[0085] In some embodiments, if the first granularity of the BWP is smaller than the reference granularity of the RBG, the terminal may not use the reference granularity of the RBG, thereby being able to correctly determine the second granularity of the RBG to support the correct determination of the number of frequency domain resources occupied by the first channel transmission.

[0086] In some embodiments, the terminal does not expect the first granularity of the BWP configured by the network to be smaller than the reference granularity of the RBG, where the reference granularity of the RBG is the granularity of the RBG determined based on protocol preset parameters and / or configuration signaling. This ensures that the number of frequency domain resources occupied by the first channel transmission can be correctly determined.

[0087] In some possible embodiments, the protocol presets that the first granularity of the configured BWP is not allowed to be smaller than the reference granularity of the RBG, where the reference granularity of the RBG is the granularity of the RBG determined based on the protocol preset parameters and / or configuration signaling. This ensures that the number of frequency domain resources occupied by the first channel transmission can be correctly determined.

[0088] In some embodiments, the first granularity of the BWP is smaller than the reference granularity of the RBG. The terminal can determine the second granularity of the RBG based on the first granularity of the BWP, the number of the starting RB of the BWP, and the reference granularity of the RBG. This allows for flexible determination of the second granularity of the RBG when the first granularity of the BWP is smaller than the reference granularity of the RBG, effectively adapting to communication scenarios with flexible BWP configurations.

[0089] In some embodiments, one or more RBGs may be divided within a BWP. The multiple RBGs may include RBGs and RBGs, and RBGs located between RBGs and RBGs in the frequency domain.

[0090] In some embodiments, if a BWP includes an RBG, then in the process of determining the second granularity of the RBG according to the first granularity of the BWP, the number of the starting RB of the BWP, and the reference granularity of the RBG, the terminal may determine the second granularity of the RBG based on a first formula, where the first formula is as follows:

[0091] in, Indicates the second granularity of RBG, represents the first granularity of BWP, The value "min" represents the starting RB number of the BWP, "i" represents the BWP index, "min" represents the minimum value, "P" represents the reference granularity of the RBG, and "mod" represents the remainder function. This allows for accurate and efficient determination of the second granularity of the RBG, ensuring the correct determination of the number of frequency domain resources occupied by the first channel transmission.

[0092] In some embodiments, if a BWP includes an RBG, then in the process of determining the second granularity of the RBG according to the first granularity of the BWP, the number of the starting RB of the BWP, and the reference granularity of the RBG, the terminal may determine the second granularity of the RBG based on a second formula, where the second formula satisfies:

[0093] if Then the second formula is:

[0094] if Then the second formula is:

[0095] in, Indicates the second granularity of RBG, represents the first granularity of BWP, The value "min" represents the starting RB number of the BWP, "i" represents the BWP index, "min" represents the minimum value, "P" represents the reference granularity of the RBG, and "mod" represents the remainder function. This allows for accurate and efficient determination of the second granularity of the RBG, ensuring that the number of frequency domain resources occupied by the first channel transmission can be correctly determined.

[0096] Step S2102: The terminal transmits the first channel according to the number of frequency domain resources.

[0097] After determining the number of frequency domain resources occupied by the first channel transmission according to the first granularity of the partial bandwidth BWP, the terminal can select the frequency domain resources occupied by the first channel transmission according to the number of frequency domain resources, and then transmit the first channel based on the selected frequency domain resources, and the network device can receive the first channel transmitted by the terminal.

[0098] The channel transmission method involved in the embodiments of the present disclosure may include at least one of steps S2101 and S2102. For example, step S2101 may be implemented as an independent embodiment, step S2102 may be implemented as an independent embodiment, and so on, but the present disclosure is not limited thereto.

Thus, the terminal can effectively determine the number of frequency domain resources occupied by the channel transmission, thereby ensuring effective transmission of the first channel.

[0101] It should be noted that, for the description of the terms and method steps in the following embodiments that are the same as or corresponding to those in the above embodiments, please refer to the above embodiments for details and will not be repeated below.

[0102] FIG2B is an interactive diagram of a channel transmission method according to another embodiment of the present disclosure. As shown in FIG2B , the embodiment of the present disclosure relates to a channel transmission method that can be used in a communication system 100. The method includes:

[0103] In step S2201, the network device determines the number of frequency domain resources occupied by the first channel transmission according to a first granularity of the BWP, where the first granularity represents the number of RBs included in the BWP.

[0104] In some embodiments, the network device may determine the number of frequency domain resources occupied by the first channel transmission according to the first granularity of the BWP.

[0105] In some embodiments, the network device can determine the second granularity of the resource block group RBG based on the first granularity of BWP, and determine the number of frequency domain resources occupied by the first channel transmission based on the second granularity of RBG, where the second granularity represents the number of RBs included in the RBG.

[0106] Therefore, the flexibility of determining the number of frequency domain resources occupied by the first channel transmission can be effectively improved, and the communication scenario with flexible BWP configuration can be effectively applied.

[0107] In some embodiments, the network device may configure a reference granularity of the RBG based on the first granularity of the BWP, and determine a second granularity of the RBG based on a first relationship between the first granularity of the BWP and the reference granularity of the RBG. This allows accurate determination of the second granularity of the RBG to support effective determination of the number of frequency domain resources occupied by the first channel transmission.

[0108] In some embodiments, the first relationship includes: a first granularity of the BWP is greater than or equal to a reference granularity of the RBG.

[0109] In some embodiments, the first granularity of the BWP is greater than or equal to the reference granularity of the RBG, and the network device may determine the second granularity of the RBG based on the reference granularity of the RBG, thereby effectively determining the second granularity of the RBG.

[0110] In some embodiments, the first relationship includes: a first granularity of the BWP is smaller than a reference granularity of the RBG.

[0111] In some embodiments, the first granularity of the BWP is smaller than the reference granularity of the RBG, and the network device may determine the second granularity of the RBG based on the first granularity of the BWP, thereby effectively determining the second granularity of the RBG.

[0112] In some embodiments, the first granularity of the BWP is smaller than the reference granularity of the RBG, and the network device may directly use the first granularity of the BWP as the second granularity of the RBG, thereby being able to effectively and quickly determine the second granularity of the RBG.

[0113] In some embodiments, the first granularity of the BWP is smaller than the reference granularity of the RBG, and the network device may determine not to use the reference granularity of the RBG, thereby correctly determining the second granularity of the RBG to support correctly determining the number of frequency domain resources occupied by the first channel transmission.

[0114] In some embodiments, if the first granularity of a BWP is smaller than the reference granularity of an RBG, the network device may determine the second granularity of the RBG based on the first granularity of the BWP, the number of the starting RB of the BWP, and the reference granularity of the RBG. This allows for flexible determination of the second granularity of the RBG even when the first granularity of the BWP is smaller than the reference granularity of the RBG, effectively adapting to communication scenarios with flexible BWP configurations.

[0115] In some embodiments, if a BWP includes an RBG, then in determining the second granularity of the RBG according to the first granularity of the BWP, the number of the starting RB of the BWP, and the reference granularity of the RBG, the network device may determine the second granularity of the RBG based on a first formula, where the first formula is as follows:

[0116] in, Indicates the second granularity of RBG, represents the first granularity of BWP, The value "min" represents the starting RB number of the BWP, "i" represents the BWP index, "min" represents the minimum value, "P" represents the reference granularity of the RBG, and "mod" represents the remainder function. This allows for accurate and efficient determination of the second granularity of the RBG, ensuring the correct determination of the number of frequency domain resources occupied by the first channel transmission.

[0117] In some embodiments, if a BWP includes an RBG, then in the process of determining the second granularity of the RBG according to the first granularity of the BWP, the number of the starting RB of the BWP, and the reference granularity of the RBG, the network device may determine the second granularity of the RBG based on a second formula, where the second formula satisfies:

[0118] if Then the second formula is:

[0119] if Then the second formula is:

[0120] in, Indicates the second granularity of RBG, represents the first granularity of BWP, The value "min" represents the starting RB number of the BWP, "i" represents the BWP index, "min" represents the minimum value, "P" represents the reference granularity of the RBG, and "mod" represents the remainder function. This allows for accurate and efficient determination of the second granularity of the RBG, ensuring that the number of frequency domain resources occupied by the first channel transmission can be correctly determined.

[0121] In some embodiments, the first granularity of the BWP configured by the network device satisfies the following constraint relationship with the reference granularity of the RBG: the first granularity of the BWP is greater than or equal to the reference granularity of the RBG configured by the network device; or the first granularity of the BWP is configured based on a pre-set protocol rule, which includes that the configured first granularity of the BWP is not allowed to be smaller than the reference granularity of the RBG configured by the network device. This ensures that the number of frequency domain resources occupied by the first channel transmission can be accurately and flexibly determined.

[0122] In some embodiments, the first channel may be, for example, a physical uplink shared channel PUSCH or a physical downlink shared channel PDSCH, thereby effectively supporting the determination of the number of frequency domain resources occupied by PUSCH and / or PDSCH transmissions.

[0123] Step S2202: The network device transmits a first channel according to the number of frequency domain resources.

[0124] After determining the number of frequency domain resources occupied by the first channel transmission according to the first granularity of the partial bandwidth BWP, the network device can select the frequency domain resources occupied by the first channel transmission according to the number of frequency domain resources, and then transmit the first channel based on the selected frequency domain resources, and the terminal can receive the first channel transmitted by the network device.

For example, step S2201 may be implemented as an independent embodiment, step S2202 may be implemented as an independent embodiment, and so on, but the present disclosure is not limited thereto.

[0127] In this embodiment, the network device determines the number of frequency domain resources occupied by the first channel transmission based on the first granularity of the BWP, and transmits the first channel based on the number of frequency domain resources. Thus, the network device can effectively determine the number of frequency domain resources occupied by channel transmission to ensure effective transmission of the first channel.
