Abstract
Description
Technical Field
[0001] The embodiments of the present application relate to the field of communications, and in particular to a resource scheduling method and related communication devices. Background Art
[0002] In the new radio (NR) system, in order to allow terminal devices with different capabilities to work in the NR system, the concept of partial bandwidth (BWP) is introduced. The BWP on a carrier refers to the frequency domain resources occupied by continuous resource blocks in this carrier. The frequency domain resources can be allocated to the terminal device by the network device according to the actual capabilities of the terminal device. For example, if the terminal device supports a maximum bandwidth of 20M, the network device may configure a BWP of 20M for the terminal device. If the terminal device can support a bandwidth of more than 20M (for example, the terminal device supports a bandwidth of 30M), the network device may configure a BWP of 30M for the terminal device.
[0003] However, when most of the terminal devices in the cell support a maximum bandwidth of 20M, and a small number of terminal devices can support bandwidths above 20M (for example, the terminal devices support a bandwidth of 30M), most of the terminal devices will be concentrated on the 20M BWP, while a small number of terminal devices will be distributed on the 30M BWP, resulting in low system bandwidth utilization efficiency of the cell, false congestion, local interference, etc. Therefore, there is an urgent need for a method for efficiently scheduling frequency domain resources to improve the system bandwidth utilization efficiency of the cell. Summary of the invention
[0004] The embodiments of the present application provide a resource scheduling method and a related communication device for improving the utilization efficiency of the cell system bandwidth.
[0005] In a first aspect, the present application provides a resource scheduling method, which involves a terminal device and a network device. The network device sends first configuration information to a first terminal device located in a first cell, and the first configuration information is used to configure a first dedicated BWP for the first terminal device; the network device receives capability information of the first terminal device through the first dedicated BWP; when the first terminal device supports the first capability, the network device sends second configuration information to the first terminal device, and the second configuration information is used to configure a second dedicated BWP for the first terminal device, and the second dedicated BWP is used to transmit the service data of the first terminal device, and the first capability is the capability of the first terminal device to support BWP without restriction.
[0006] The frequency domain position of the first dedicated BWP is the same as the frequency domain position of the initial BWP of the first cell, and the frequency domain position of the second dedicated BWP is different from the frequency domain position of the initial BWP.
[0007] Among them, the first capability refers to the BWP unrestricted capability (BWP_WithOutRestirction capability): used to indicate that the terminal device supports BWP operation without bandwidth restrictions. That is to say, if the terminal device supports the BWP unrestricted capability (BWP_WithOutRestirction capability), the BWP configured by the network device for the terminal device may not necessarily include an initial BWP (for example, an initial downlink BWP (initial DL BWP)) or SSB. Therefore, when the first terminal device supports the first capability, the network device can more flexibly configure a second dedicated BWP for the first terminal device.
[0008] In this embodiment, the network device configures a BWP (i.e., a first dedicated BWP) with the same frequency domain position as the initial BWP for the first terminal device to report the capability information (e.g., first capability information) of the first terminal device, and after learning that the first terminal device supports the first capability (i.e., the capability to support BWP without restrictions), a BWP with a frequency domain position different from the initial BWP is configured for the first terminal device for transmitting service data. Therefore, the first terminal device does not need to be concentrated on the initial BWP with other terminal devices, but can be located at other frequency domain positions in the system bandwidth, which is conducive to improving the utilization rate of the system bandwidth.
[0009] In traditional technology, the network device will not configure a dedicated BWP for the terminal device to report the first capability information, nor will it first configure a BWP for the terminal device to upload the first capability information, and then configure a BWP for the terminal device to transmit service data based on the first capability information. In traditional technology, the terminal device directly configures a dedicated BWP for transmitting service data for the terminal device based on the information about the terminal device obtained from the initial BWP. Since the network device in the traditional technology does not obtain the first capability information, and it is unclear whether the terminal device supports the first capability (i.e., the BWP unrestricted capability (BWP_WithOutRestirction capability)), the network device can only configure a dedicated BWP for the terminal device that contains the frequency domain position of the initial BWP to transmit service data, resulting in the terminal devices in the cell being concentrated near the frequency domain position of the initial BWP, affecting the utilization of the system bandwidth.
[0010] In a possible implementation, the terminal devices in the first cell include terminal devices of a first type and terminal devices of a second type, the maximum system bandwidth supported by the terminal devices of the first type is smaller than the maximum system bandwidth supported by the terminal devices of the second type, the system bandwidth of the first cell is larger than the maximum system bandwidth supported by the terminal devices of the first type, and the first terminal device belongs to the terminal device of the first type or to the terminal device of the second type.
[0011] In this embodiment, it is proposed that the first cell includes multiple types of terminal devices, each type of terminal device supports a different maximum system bandwidth, and the system bandwidth of the first cell is greater than the maximum system bandwidth supported by one or more types of terminal devices.
[0012] Exemplarily, the first type of terminal device is a long term evolution (LTE) terminal device, and the second type of terminal device is an NR terminal device (or the 6th generation mobile communication technology (6G) terminal device). Since the maximum system bandwidth supported by the LTE terminal device is 20M, and the maximum system bandwidth supported by the NR terminal device (or 6G terminal device) is greater than 20M, the system bandwidth of the first cell in this example is at least greater than 20M.
[0013] In a possible implementation manner, the bandwidth of the initial BWP is less than or equal to the maximum system bandwidth supported by the first type of terminal equipment.
[0014] It should be understood that the initial BWP is a cell-level BWP configured by the network device before sending the first configuration information. The initial BWP may be configured through the first system information block (System Information Block Type 1, SIB1), and the initial BWP may also be determined by CORESET0, which is not specifically limited here.
[0015] In this embodiment, it is proposed that the bandwidth of the initial BWP of the first cell needs to be less than or equal to the maximum system bandwidth supported by the terminal device with a smaller bandwidth in the first cell, so as to ensure that the terminal devices in the first cell can access the first cell through the initial BWP. Exemplarily, if there are terminal devices supporting a maximum system bandwidth of 20M (referred to as 20M terminal devices), terminal devices supporting a maximum system bandwidth of 30M (referred to as 30M terminal devices), and terminal devices supporting a maximum system bandwidth of 50M (referred to as 50M terminal devices) in the first cell, the size of the initial BWP of the first cell needs to be less than or equal to 20M.
[0016] In addition, since the frequency domain position of the first dedicated BWP is the same as the frequency domain position of the initial BWP of the first cell, if the first terminal device can access the initial BWP, then the first terminal device can also access the first dedicated BWP. Therefore, it is helpful to improve the success rate of the first terminal device accessing the cell.
[0017] In a possible implementation manner, the maximum system bandwidth supported by the first type of terminal equipment is 20M.
[0018] In a possible implementation manner, the bandwidth of the second dedicated BWP is the maximum system bandwidth supported by the first terminal device.
[0019] In this embodiment, if the capability information of the first terminal device reported to the network device by the first terminal device through the first dedicated BWP includes the maximum system bandwidth supported by the first terminal device, the size of the second dedicated BWP configured by the network device for the first terminal device may be equal to the maximum system bandwidth supported by the first terminal device. In this case, it is not only beneficial to improve the utilization rate of the system bandwidth, but also beneficial to ensure the efficiency of the first terminal device in transmitting service data.
[0020] In a possible implementation, the network device stores a first candidate BWP set, the first candidate BWP set including N candidate BWPs, the frequency domain positions of the N candidate BWPs are different, the union of the frequency domain positions of the N candidate BWPs is equal to the frequency domain position of the system bandwidth of the first cell, and N is an integer greater than 1. The frequency domain position of the initial BWP is the same as the frequency domain position of one of the N candidate BWPs, and the frequency domain position of the second dedicated BWP is the same as the frequency domain position of another of the N candidate BWPs.
[0021] It should be understood that there may be a non-empty intersection between the frequency domain positions of two adjacent BWPs in the aforementioned N candidate BWPs, or there may not be a non-empty intersection, which is not specifically limited here.
[0022] In this embodiment, it is proposed that a candidate BWP set (i.e., a first candidate BWP set) is stored in the network device, and the network device can directly select BWPs located at different frequency domain positions from the first candidate BWP set as the initial BWP and the second dedicated BWP. In addition, the N candidate BWPs in the first candidate BWP set can cover the entire system bandwidth. If the network device configures different terminal devices in the first cell in the N candidate BWPs according to the aforementioned first candidate BWP set, the terminal devices in the first cell can be distributed more evenly on the system bandwidth, rather than being concentrated in a certain frequency domain position.
[0023] In a possible implementation, before the network device sends the first configuration information to the first terminal device located in the first cell, the method also includes: the network device determines the first candidate BWP set based on the type information of the terminal device in the first cell and the system bandwidth of the first cell; wherein the type information of the terminal device is used to indicate the ratio of the number of different types of terminal devices in the first cell, and the maximum system bandwidths supported by the different types of terminal devices are different.
[0024] In this implementation, it is proposed that the first candidate BWP set may be determined by the network device based on a preset rule, for example, the network device determines the first candidate BWP set based on the type information of the terminal device in the first cell and the system bandwidth of the first cell. It should be understood that the type information of the terminal device in the first cell is determined based on the terminal devices accessing the first cell within a certain period of time in history.
[0025] In a possible implementation, the method also includes: the network device sends third configuration information to the first terminal device, and the third configuration information is used to configure the frequency domain position of the physical uplink control channel (PUCCH) in the second dedicated BWP to be adjacent to the frequency domain position of the PUCCH in the first dedicated BWP.
[0026] Exemplarily, the third configuration information is information for indicating the frequency domain position of the PUCCH in the second dedicated BWP, for example, the code channel number of the PUCCH of the second dedicated BWP. Since the frequency domain position of the PUCCH in the second dedicated BWP is adjacent to the frequency domain position of the PUCCH in the first dedicated BWP, the discontinuous scheduling frequency of the physical uplink shared channel PUSCH caused by the PUCCH cutoff can be reduced, which is conducive to improving the utilization efficiency of frequency domain resources.
[0027] Optionally, the PUCCH configured by the third configuration information is a dedicated PUCCH, which is mainly used to receive ACK feedback corresponding to the physical downlink shared channel (PDSCH) after the terminal device (for example, the first terminal device) accesses, and to report channel state information (CSI) and reference signal (RS) related information to the network device.
[0028] In a possible implementation, when the frequency domain position of the first dedicated BWP is adjacent to the frequency domain position of the second dedicated BWP, the PUCCH in the second dedicated BWP is located on the side close to the PUCCH of the first dedicated BWP; when the frequency domain position of the first dedicated BWP and the frequency domain position of the second dedicated BWP have a non-empty intersection, part or all of the PUCCH in the second dedicated BWP is located in the non-empty intersection.
[0029] In a possible implementation manner, the intersection of the frequency domain position of the second dedicated BWP and the frequency domain position of the initial BWP is empty.
[0030] In the second aspect, the present application provides a resource scheduling method, which involves a terminal device and a network device. Among them, a first terminal device receives first configuration information from a network device, the first terminal device is located in a first cell of the network device, the first configuration information is used to configure a first dedicated BWP for the first terminal device, and the frequency domain position of the first dedicated BWP is the same as the frequency domain position of the initial BWP of the first cell; the first terminal device sends the capability information of the first terminal device to the network device through the first dedicated BWP, the capability information of the first terminal device includes first capability information, and the first capability information is used to indicate that the first terminal device supports the unrestricted capability of BWP; the first terminal device receives second configuration information from the network device, the second configuration information is used to configure a second dedicated BWP for the first terminal device, the frequency domain position of the second dedicated BWP is different from the frequency domain position of the initial BWP, and the second dedicated BWP is used to transmit the service data of the first terminal device.
[0031] In this embodiment, the first terminal device receives first configuration information from the network device to determine a first dedicated BWP for reporting capability information of the first terminal device, and the frequency domain position of the first dedicated BWP is the same as the frequency domain position of the initial BWP. If the first terminal device supports the first capability (i.e., supports the capability of unrestricted BWP), after the network device learns that the first terminal device supports the first capability, it configures a BWP (i.e., a second dedicated BWP) for the first terminal device that is different from the frequency domain position of the initial BWP for transmitting service data. Therefore, the first terminal device does not need to be concentrated on the initial BWP with other terminal devices, but can be located at other frequency domain positions in the system bandwidth, which is beneficial to improve the utilization of the system bandwidth.
[0032] In a possible implementation, the terminal devices in the first cell include terminal devices of a first type and terminal devices of a second type, the maximum system bandwidth supported by the terminal devices of the first type is smaller than the maximum system bandwidth supported by the terminal devices of the second type, the system bandwidth of the first cell is larger than the maximum system bandwidth supported by the terminal devices of the first type, and the first terminal device belongs to the terminal device of the first type or to the terminal device of the second type.
[0033] In this embodiment, it is proposed that the first cell includes multiple types of terminal devices, each type of terminal device supports a different maximum system bandwidth, and the system bandwidth of the first cell is greater than the maximum system bandwidth supported by one or more types of terminal devices.
[0034] Exemplarily, the first type of terminal device is an LTE terminal device, and the second type of terminal device is an NR terminal device (or a 6G terminal device). Since the maximum system bandwidth supported by the LTE terminal device is 20M, and the maximum system bandwidth supported by the NR terminal device (or a 6G terminal device) is greater than 20M, the system bandwidth of the first cell in this example is at least greater than 20M.
[0035] In a possible implementation manner, the bandwidth of the initial BWP is less than or equal to the maximum system bandwidth supported by the first type of terminal equipment.
[0036] It should be understood that the initial BWP is a cell-level BWP configured by the network device before sending the first configuration information. The initial BWP may be configured through the first system information block SIB1, or may be determined by CORESET0, which is not specifically limited here.
[0037] In this embodiment, it is proposed that the bandwidth of the initial BWP of the first cell needs to be less than or equal to the maximum system bandwidth supported by the terminal device with a smaller bandwidth in the first cell, so as to ensure that the terminal devices in the first cell can access the first cell through the initial BWP. Exemplarily, if there are terminal devices supporting a maximum system bandwidth of 20M (referred to as 20M terminal devices), terminal devices supporting a maximum system bandwidth of 30M (referred to as 30M terminal devices), and terminal devices supporting a maximum system bandwidth of 50M (referred to as 50M terminal devices) in the first cell, the size of the initial BWP of the first cell needs to be less than or equal to 20M.
[0038] In addition, since the frequency domain position of the first dedicated BWP is the same as the frequency domain position of the initial BWP of the first cell, if the first terminal device can access the initial BWP, then the first terminal device can also access the first dedicated BWP. Therefore, it is helpful to improve the success rate of the first terminal device accessing the cell.
[0039] In a possible implementation manner, the maximum system bandwidth supported by the first type of terminal equipment is 20M.
[0040] In a possible implementation manner, the bandwidth of the second dedicated BWP is the maximum system bandwidth supported by the first terminal device.
[0041] In this embodiment, if the capability information of the first terminal device reported to the network device by the first terminal device through the first dedicated BWP includes the maximum system bandwidth supported by the first terminal device, the size of the second dedicated BWP configured by the network device for the first terminal device may be equal to the maximum system bandwidth supported by the first terminal device. In this case, it is not only beneficial to improve the utilization rate of the system bandwidth, but also beneficial to ensure the efficiency of the first terminal device in transmitting service data.
[0042] In a possible implementation, the method further includes: the first terminal device receives third configuration information from the network device, and the third configuration information is used to configure the frequency domain position of the physical uplink control channel PUCCH in the second dedicated BWP to be adjacent to the frequency domain position of the PUCCH in the first dedicated BWP.
[0043] Exemplarily, the third configuration information is information for indicating the frequency domain position of the PUCCH in the second dedicated BWP, for example, the code channel number of the PUCCH of the second dedicated BWP. Since the frequency domain position of the PUCCH in the second dedicated BWP is adjacent to the frequency domain position of the PUCCH in the first dedicated BWP, the discontinuous scheduling frequency of the physical uplink shared channel (PUSCH) caused by the PUCCH cutoff can be reduced, which is conducive to improving the utilization efficiency of frequency domain resources.
[0044] Optionally, the PUCCH configured by the third configuration information is a dedicated PUCCH, which is mainly used to receive ACK feedback corresponding to the physical downlink shared channel (PDSCH) after the terminal device (for example, the first terminal device) accesses, and to report relevant information of channel state information CSI and reference signal RS to the network device.
[0045] In a possible implementation, when the frequency domain position of the first dedicated BWP is adjacent to the frequency domain position of the second dedicated BWP, the PUCCH in the second dedicated BWP is located on the side close to the PUCCH of the first dedicated BWP; when the frequency domain position of the first dedicated BWP and the frequency domain position of the second dedicated BWP have a non-empty intersection, part or all of the PUCCH in the second dedicated BWP is located in the non-empty intersection.
[0046] In a possible implementation manner, the intersection of the frequency domain position of the second dedicated BWP and the frequency domain position of the initial BWP is empty.
[0047] It should be noted that there are many other specific implementations of the embodiments of the present application. Please refer to the specific implementations of the first aspect and their beneficial effects for details, which will not be repeated here.

The transceiver module is used to send first configuration information to a first terminal device located in a first cell, and the first configuration information is used to configure a first dedicated BWP for the first terminal device, and the frequency domain position of the first dedicated BWP is the same as the frequency domain position of the initial BWP of the first cell. The transceiver module is also used to receive capability information of the first terminal device through the first dedicated BWP. The processing module parses the capability information of the first terminal device, and when the first terminal device supports the first capability, controls the transceiver module to send second configuration information to the first terminal device, and the second configuration information is used to configure a second dedicated BWP for the first terminal device, and the frequency domain position of the second dedicated BWP is different from the frequency domain position of the initial BWP, and the second dedicated BWP is used to transmit the service data of the first terminal device, and the first capability is the capability of the first terminal device to support BWP without restriction.

Therefore, the first terminal device does not need to be concentrated on the initial BWP with other terminal devices, but can be located at other frequency domain positions in the system bandwidth, which is conducive to improving the utilization of the system bandwidth. In addition, when the bandwidth size of the second dedicated BWP is the maximum system bandwidth supported by the first terminal device, it is not only conducive to improving the utilization of the system bandwidth, but also conducive to ensuring the efficiency of the first terminal device in transmitting service data.

[0097] The technical solutions in the embodiments of the present application will be clearly and completely described below in conjunction with the drawings in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, rather than all of the embodiments.
[0098] The terms "first", "second", "third", "fourth", etc. (if any) in the specification and claims of the present application and the above-mentioned drawings are used to distinguish similar objects, and are not necessarily used to describe a specific order or sequence. It should be understood that the data used in this way can be interchangeable where appropriate, so that the embodiments described herein can be implemented in an order other than that illustrated or described herein. In addition, the terms "including" and "having" and any variations thereof are intended to cover non-exclusive inclusions, for example, a process, method, system, product or device that includes a series of steps or units is not necessarily limited to those steps or units that are clearly listed, but may include other steps or units that are not clearly listed or inherent to these processes, methods, products or devices.
[0099] To facilitate understanding of the solution proposed in this application, the following is an introduction to the professional terms involved in this application:
[0100] Bandwidth part (BWP): A concept of frequency domain resources introduced to allow terminal devices with different capabilities to work in the new radio (NR) system. The BWP on a carrier refers to the frequency domain resources occupied by continuous resource blocks in this carrier. The frequency domain resources can be allocated to the terminal device by the network device according to the actual capabilities of the terminal device. Generally, BWP includes initial bandwidth part (Initial BWP) and dedicated bandwidth part (Dedicated BWP).
[0101] Initial BWP: a cell-level BWP used for receiving or sending information before a terminal device in an idle or inactive state accesses a network device, for example, system information related to random access (RA).
[0102] Dedicated BWP: also known as configured BWP, refers to the BWP dedicated to the terminal device, which is configured by the network device to the terminal device for executing certain specific services.
[0103] BWP unrestricted capability (BWP_WithOutRestirction capability): used to indicate that the terminal device supports BWP operation without bandwidth restriction. Among them, for the BWP of the primary cell (PCell) and the BWP of the service cell (PSCell) of the primary cell, the bandwidth restriction means that the dedicated BWP of the terminal device (for example, a UE-specific RRC configured BWP) may not include the initial BWP (for example, the initial downlink BWP (initial DL BWP)) and the synchronization signal / broadcast channel block (SS / PBCH block, SSB). For the BWP of the secondary cell, the aforementioned bandwidth restriction means that the bandwidth of the BWP may not include SSB. In other words, if the terminal device supports the BWP unrestricted capability (BWP_WithOutRestirction capability), the BWP configured by the network device for the terminal device may not be required to include the initial BWP (for example, the initial downlink BWP (initial DLBWP)) or SSB.
[0104] The maximum system bandwidth supported by the terminal device refers to the maximum bandwidth of the beam that can be transmitted, which is determined by the radio frequency capability of the terminal device. Generally, the maximum system bandwidth supported by LTE terminal devices is 20M, and the system bandwidth supported by the terminal device can be 5M, 10M, and 15M, etc. The maximum system bandwidth of 5G NR terminal devices (or 6G terminal devices) is greater than 20M, and can reach up to 100M. The system bandwidth supported by the terminal device includes not only 5M, 10M, 15M, and 20M, but also 30M, 50M, 60M, etc.
[0105] Time-frequency resource: refers to the physical resource that carries the channel. Generally, time-frequency resources can be represented by resource blocks (RB) and resource elements (RE) according to the different granularity of division. Among them, one RB occupies one symbol in the time domain (for example, orthogonal frequency division multiplexing (OFDM) symbol) and 12 subcarriers in the frequency domain. One RE occupies one symbol in the time domain and one subcarrier in the frequency domain. One RB contains 12 REs.
[0106] Control resource set (CORESET): refers to the set of time-frequency resources that carry control channels (e.g., physical downlink control channel (PDCCH)). Generally, the basic component unit of CORESET is resource element group (REG), and 1 REG corresponds to 1 PRB on 1 OFDM symbol. The number of REGs contained in CORESET is generally an integer multiple of 6.
[0107] For ease of understanding, the system architecture and application scenarios of the resource scheduling method proposed in this application are first introduced below:
[0108] The communication method proposed in this application can be applied to 5G NR (5G New Radio) system, the 6th generation mobile communication technology (6G) system and subsequent evolution standards, and this application does not limit this. The communication system includes at least one terminal device and at least one network device.
[0109] Among them, the terminal device includes a device that provides voice and / or data connectivity to the user. For example, it may include a handheld device with a wireless connection function or a processing device connected to a wireless modem. The terminal device can communicate with a core network (e.g., 5G core network (5th generation core, 5GC)) via a radio access network (RAN), and can exchange voice and / or data with the RAN. The terminal device may also be referred to as a terminal (Terminal), user equipment (UE), wireless terminal equipment, mobile terminal (MT) equipment, subscriber unit, subscriber station, mobile station (MS), mobile station (mobile), remote station (remote station), access point (AP), remote terminal equipment (remote terminal), access terminal equipment (access terminal), user terminal equipment (user terminal), user agent (user agent), or user equipment (user device), etc. In addition, the terminal device can be a mobile phone, a tablet computer, a computer with wireless transceiver function, a virtual reality (VR) terminal device, an augmented reality (AR) terminal device, a wireless terminal in industrial control, a wireless terminal in self-driving, a wireless terminal in remote medical surgery, a wireless terminal in smart grid, a wireless terminal in transportation safety, a wireless terminal in smart city, a wireless terminal in smart home, etc. It should be noted that the terminal devices involved in this application include terminals that support a maximum system bandwidth of 20M (hereinafter referred to as small bandwidth terminal devices for ease of introduction) and terminals that support a maximum system bandwidth greater than 20M (hereinafter referred to as large bandwidth terminal devices for ease of introduction). It should be understood that the embodiments of this application do not limit the specific technology and specific device form adopted by the terminal device. The terminal device in this application can be any of the above-mentioned devices or chips, which are not specifically limited here. Whether as a device or as a chip, the terminal device can be manufactured, sold or used as an independent product.In this embodiment and subsequent embodiments, only the terminal device is taken as an example for introduction.
[0110] A network device may be any device with a wireless transceiver function, and may be used to be responsible for functions related to the air interface, such as a wireless link maintenance function, a wireless resource management function, and some mobility management functions. Among them, the wireless link maintenance function is used to maintain the wireless link with the terminal device, and is responsible for the protocol conversion between the wireless link data and the Internet Protocol (IP) data; the wireless resource management function may include functions such as the establishment and release of the wireless link, the scheduling and allocation of wireless resources; and some mobility management functions may include configuring the terminal device for measurement, evaluating the quality of the wireless link of the terminal device, and deciding the switching of the terminal device between cells. Exemplarily, the network device may be an access network device (radio access network, RAN) that currently provides services to the terminal device. For example, the network device may include a next generation node B (next generation node B, gNB) in a 5G new radio (new radio, NR) system, or may also include a centralized unit (centralized unit, CU) and a distributed unit (distributed unit, DU) in a cloud access network (CloudRAN) system. The former network device may also include a node in a 6G system (e.g., xNodeB). It is not limited here. It should be understood that the network device in the embodiment of the present application can be any of the above-mentioned devices or chips in the above-mentioned devices, and is not specifically limited here. Whether as a device or as a chip, the network device can be manufactured, sold or used as an independent product. In this embodiment and subsequent embodiments, only the network device is used as an example for introduction.
[0111] In addition, the resource scheduling method of the present application can be applied to the scenario where the system bandwidth of the cell is greater than (or much greater than) the maximum system bandwidth supported by the terminal equipment in the cell. Figure 1 As shown, in the conventional technology, when the network device configures a dedicated BWP for each terminal device in the cell, the frequency domain range of the dedicated BWP of each terminal device is required to include the frequency domain range of the initial BWP of the cell. When the system bandwidth of the cell is large, and there are many terminal devices in the cell whose maximum system bandwidth supported is smaller than (or much smaller than) the system bandwidth of the cell, the frequency domain position of the BWP configured by the network device for the aforementioned terminal device on the system bandwidth will be restricted, thereby affecting the utilization efficiency of the system bandwidth.
[0112] by Figure 1For example, if the system bandwidth of a cell is 50M, the initial BWP (i.e., BWP0) is 10M, and the maximum system bandwidth supported by most terminal devices in the cell is 20M, while the maximum system bandwidth supported by a small number of terminal devices is greater than 20M ( Figure 1 Taking a terminal device supporting a maximum system bandwidth of 30M as an example), the network device may be a part of the terminal devices (for example, Figure 1 The maximum system bandwidth supported by the terminal device is 30M) and a dedicated BWP (i.e., BWP1_3) with a bandwidth of 30M is configured for another part of the terminal devices (e.g., Figure 1 The maximum system bandwidth supported by the terminal device is 20M) configures two 20M dedicated BWPs (i.e., BWP1_1 and BWP1_2). At this time, the intersection of the two 20M BWPs is the initial BWP. This resource scheduling method will cause the terminal devices to be concentrated on the two 20M BWPs, while other frequency domain locations on the system bandwidth (for example, Figure 1 In the case of a cell, there are only a few terminal devices distributed at both ends of the system bandwidth, which results in low efficiency in utilizing the system bandwidth of the cell and waste of spectrum resources.
[0113] In this regard, the present application proposes a resource scheduling method, which can allocate BWP to the terminal device based on the capability of the terminal device when the terminal device accesses the network, so as to avoid the terminal devices in the cell being concentrated in a dedicated BWP including the initial BWP, thereby facilitating the terminal devices to be concentrated in a certain frequency domain position in the system bandwidth instead of being concentrated in a certain BWP.
[0114] The following will be combined Figure 2 The main process of the resource scheduling method proposed in this application is introduced:
[0115] Step 201: A network device sends first configuration information to a first terminal device, where the first configuration information is used to configure a first dedicated BWP for the first terminal device. Accordingly, the first terminal device receives the first configuration information from the network device.
[0116] The first terminal device is a terminal device located in a first cell, and the first cell may include a plurality of the aforementioned first terminal devices.
[0117] Among them, the first cell is a cell under the network device, and the system bandwidth of the first cell is greater than (or much greater than) the maximum system bandwidth supported by some terminal devices in the first cell. The first cell includes multiple types of terminal devices, and the maximum system bandwidth supported by each type of terminal device is different. The system bandwidth of the first cell is greater than the maximum system bandwidth supported by one or more types of terminal devices. Exemplarily, the first cell includes 5M terminal devices (i.e., terminal devices supporting a maximum system bandwidth of 5M), 10M terminal devices (i.e., terminal devices supporting a maximum system bandwidth of 10M), 20M terminal devices (i.e., terminal devices supporting a maximum system bandwidth of 20M), 30M terminal devices (i.e., terminal devices supporting a maximum system bandwidth of 30M), 50M terminal devices (i.e., terminal devices supporting a maximum system bandwidth of 50M) and 100M terminal devices (i.e., terminal devices supporting a maximum system bandwidth of 100M), etc. It should be understood that with the development of communication technology, in actual applications, there may also be terminal devices that support system bandwidths of other sizes, and the specific embodiments will not be listed one by one.
[0118] Optionally, the first cell includes at least a first type of terminal device and a second type of terminal device, wherein the maximum system bandwidth supported by the first type of terminal device is smaller than the maximum system bandwidth supported by the second type of terminal device, and the system bandwidth of the first cell is larger than the maximum system bandwidth supported by the first type of terminal device. Exemplarily, the first type of terminal device is an LTE terminal device, and the second type of terminal device is an NR terminal device (or 6G terminal device). Since the maximum system bandwidth supported by the LTE terminal device is 20M, and the maximum system bandwidth supported by the NR terminal device (or 6G terminal device) is greater than 20M, the system bandwidth of the first cell in this example is at least greater than 20M.
[0119] Since the terminal devices in the current traditional technology mainly include LTE terminal devices (supporting a maximum system bandwidth of 20M) (also known as R15 existing terminals) and NR terminal devices (i.e., supporting a maximum system bandwidth greater than 20M), in the subsequent embodiments, the terminal devices in the first cell will be taken as an example to mainly include LTE terminal devices and NR terminal devices.
[0120] It should be noted that in this embodiment, the first terminal device may be the aforementioned first type of terminal device, or may be the aforementioned second type of terminal device, which is not specifically limited here.
[0121] In addition, the first configuration information is used to configure a first dedicated BWP for the first terminal device, and the first dedicated BWP is used to transmit the capability information of the first terminal device. That is to say, after the first terminal device receives the aforementioned first configuration information, the first terminal device can know on which time-frequency resource to report the capability information of the first terminal device to the network device.
[0122] It should be understood that the network device can send the first configuration information to the first terminal device in a variety of ways. In one possible implementation, the network device can carry the first configuration information in the proprietary signaling of the first terminal device. For example, the network device can send the aforementioned first configuration information to the first terminal device via proprietary radio resource control (RRC) signaling, so that the first terminal device can obtain the first configuration information from the RRC signaling. Optionally, the network device can carry the first configuration information in downlink control information (DCI), which is not specifically limited here.
[0123] In this embodiment, the frequency domain position of the first dedicated BWP is the same as the frequency domain position of the initial BWP of the first cell. Specifically, it can be understood that the starting RB and the number of occupied RBs of the first dedicated BWP and the initial BWP are the same. It can also be understood that the starting RB and bandwidth size of the first dedicated BWP and the initial BWP are the same. In this embodiment, since the frequency domain position of the first dedicated BWP is the same as the frequency domain position of the initial BWP of the first cell, if the first terminal device supports the bandwidth size of the initial BWP, the first terminal device can also support the bandwidth size of the first dedicated BWP. Therefore, it is beneficial to improve the success rate of the first terminal device accessing the cell.
[0124] It should be understood that the initial BWP is a cell-level BWP configured by the network device before step 201. The initial BWP may be configured through the first system information block SIB1, or may be determined by CORESET0, which is not specifically limited here.
[0125] Optionally, the bandwidth of the initial BWP is less than or equal to the maximum system bandwidth supported by the first type of terminal equipment. Since the frequency domain position of the first dedicated BWP is the same as the frequency domain position of the initial BWP of the first cell, the bandwidth of the first dedicated BWP is also less than or equal to the maximum system bandwidth supported by the first type of terminal equipment. Exemplarily, if the maximum system bandwidth supported by the first type of terminal equipment is 20M, the bandwidth of the initial BWP is less than or equal to 20M, and the bandwidth of the first dedicated BWP is also less than or equal to 20M. If there are many terminal equipment in the first cell that support a maximum system bandwidth of 20M, configuring the bandwidth of the initial BWP and the bandwidth of the first dedicated BWP to be less than or equal to 20M is beneficial to ensure that terminal equipment with lower capabilities can successfully access the first cell.
[0126] In this embodiment, after the first terminal device receives the first configuration information, the first terminal device can determine the frequency domain resources of the first dedicated BWP. Then, the first terminal device will execute step 202.
[0127] Step 202: The first terminal device sends the capability information of the first terminal device to the network device through the first dedicated BWP; correspondingly, the network device receives the capability information of the first terminal device through the first dedicated BWP.
[0128] Optionally, the capability information of the first terminal device includes a maximum system bandwidth supported by the first terminal device. Optionally, the capability information of the first terminal device may also include an amount of resources required by the first terminal device to transmit a service.
[0129] In addition, the capability information of the first terminal device also includes first capability information, and the first capability information is used to indicate that the first terminal device supports the first capability, that is, indicates that the first terminal device supports the capability of BWP without restrictions. Specifically, the first capability information is used to indicate that the first terminal device supports the BWP_WithOutRestirction capability, that is, the first terminal device supports BWP operation without bandwidth restrictions. It can also be understood that the first terminal device can use a dedicated BWP that does not include an initial BWP or SSB to send service data to a network device.
[0130] It should be understood that the first terminal device may also send the maximum system bandwidth supported by the first terminal device and / or the amount of resources required for the first terminal device to transmit services to the network device through the initial BWP, which is not specifically limited here. However, in conventional technology, the terminal device will not send the first capability information (i.e., information indicating that the terminal device supports the first capability (BWP_WithOutRestirction capability)) to the network device through the initial BWP.
[0131] When the capability information of the first terminal device includes the first capability information, the network device will execute step 203.
[0132] Step 203: When the first terminal device supports the first capability, the network device sends second configuration information to the first terminal device, where the second configuration information is used to configure a second dedicated BWP for the first terminal device; accordingly, the first terminal device receives the second configuration information from the network device.
[0133] The second dedicated BWP is used to transmit the service data of the first terminal device. That is to say, after the first terminal device receives the aforementioned second configuration information, the first terminal device can determine the frequency domain position of the second dedicated BWP. In addition, if the first terminal device needs to transmit service data, the first terminal device will send the service data to the network device through the second dedicated BWP.
[0134] Since the first terminal device supports the first capability, that is, the first terminal device supports the BWP_WithOutRestirction capability, the first terminal device can transmit service data to the network device on the second dedicated BWP that does not include the initial BWP and / or SSB. Therefore, in this embodiment, the frequency domain position of the second dedicated BWP is different from the frequency domain position of the initial BWP.
[0135] In a possible implementation, for example Figure 3A As shown, the frequency domain position of the second dedicated BWP and the frequency domain position of the initial BWP have a non-empty intersection (hereinafter referred to as the first frequency domain resource for ease of introduction). At this time, the frequency domain position of the first dedicated BWP and the frequency domain position of the second dedicated BWP also have a non-empty intersection (i.e., the aforementioned first frequency domain resource). In another possible implementation, the frequency domain position of the second dedicated BWP and the frequency domain position of the initial BWP do not have a non-empty intersection, and the frequency domain position of the first dedicated BWP may be adjacent to the frequency domain position of the initial BWP, such as Figure 3B As shown; the frequency domain of the first dedicated BWP may not be adjacent to the frequency domain position of the initial BWP, such as Figure 3C shown.
[0136] It should be understood that Figure 3A , Figure 3B as well as Figure 3C The example shown is a portion of the frequency domain resources in the system bandwidth. Figure 3A , Figure 3B as well as Figure 3C The three examples shown may exist simultaneously in the system bandwidth, for example Figure 3D At this time, Figure 3DThe multiple second dedicated BWPs (i.e., second dedicated BWP1, second dedicated BWP2, and second dedicated BWP3) in the first cell are respectively BWPs allocated by the network device to different terminal devices in the first cell for transmitting service data. That is to say, when there are multiple terminal devices in the first cell, the first network device allocates second dedicated BWPs with different frequency domain positions to the terminal devices supporting the first capability, which is conducive to avoiding the terminal devices from being concentrated on the first dedicated BWP (or initial BWP), and is also conducive to making the terminal devices in the first cell more evenly distributed on the system bandwidth, that is, some terminal devices exist on the dedicated BWP (i.e., the first dedicated BWP) including the initial BWP, and some terminal devices also exist on each dedicated BWP (i.e., the second dedicated BWP) not including the initial BWP.
[0137] In addition, it should be understood that the number of RBs occupied by the second dedicated BWP may be the same as or different from the number of RBs occupied by the initial BWP. Figure 3A , Figure 3B , Figure 3C as well as Figure 3D In the example shown, the number of RBs occupied by the second dedicated BWP may be the same as or different from the number of RBs occupied by the initial BWP, which is not specifically limited here.
[0138] Optionally, if the capability information of the first terminal device sent by the first terminal device to the network device carries the maximum system bandwidth supported by the first terminal device, or the first terminal device sends the maximum system bandwidth supported by the first terminal device to the network device through the initial BWP, then the bandwidth of the second dedicated BWP configured by the network device for the first terminal device through the second configuration information can be the maximum system bandwidth supported by the first terminal device. At this time, the first terminal device can use the maximum system bandwidth supported by the first terminal device to transmit service data, which is conducive to ensuring the efficiency of the first terminal device in transmitting service data.
[0139] It should be understood that the network device can send the second configuration information to the first terminal device in a variety of ways. In one possible implementation, the network device can carry the second configuration information in the dedicated signaling of the first terminal device. For example, the network device can send the aforementioned second configuration information to the first terminal device via dedicated radio resource control RRC signaling, so that the first terminal device can obtain the second configuration information from the RRC signaling. Optionally, the network device can carry the second configuration information in the downlink control information DCI, which is not specifically limited here.
[0140] In this embodiment, the network device configures a BWP (i.e., a first dedicated BWP) with the same frequency domain position as the initial BWP for the first terminal device to report the capability information of the first terminal device, and after learning that the first terminal device supports the first capability (i.e., the capability to support unrestricted BWP), a BWP (i.e., a second dedicated BWP) with a frequency domain position different from the initial BWP is configured for the first terminal device for transmitting service data. Therefore, the first terminal device does not need to be concentrated on the initial BWP with other terminal devices, but can be located at other frequency domain positions in the system bandwidth, which is conducive to improving the utilization of the system bandwidth. In addition, when the bandwidth size of the second dedicated BWP is the maximum system bandwidth supported by the first terminal device, it is not only conducive to improving the utilization of the system bandwidth, but also conducive to ensuring the efficiency of the first terminal device in transmitting service data.
[0141] The following will be combined Figure 4 The process of the resource scheduling method proposed in this application is further introduced:
[0142] Step 401: The network device obtains a first candidate BWP set.
[0143] Among them, the first candidate BWP set includes N candidate BWPs, the frequency domain positions of the N candidate BWPs are different, the union of the frequency domain positions of the N candidate BWPs is equal to the frequency domain position of the system bandwidth of the first cell, and N is an integer greater than 1. It can also be understood that the N candidate BWPs in the first candidate BWP set can cover the entire system bandwidth. If the network device configures different terminal devices in the first cell in the N candidate BWPs according to the aforementioned first candidate BWP set, the terminal devices in the first cell can be distributed more evenly on the system bandwidth, rather than the terminal devices being concentrated in a certain frequency domain position. In addition, the network device configuring a BWP for the first terminal device according to the predetermined first candidate BWP set is conducive to reducing frequency domain resource fragmentation on the system bandwidth.
[0144] It should be understood that the arrangement positions of the N candidate BWPs in the aforementioned first candidate BWP set may be implemented in a variety of ways.
[0145] In a possible implementation manner, there may be a non-empty intersection between the frequency domain positions of two adjacent BWPs in the aforementioned N candidate BWPs. Figure 5AFor example, the first candidate BWP set may include 5 candidate BWPs, wherein the number of RBs occupied by these 5 candidate BWPs is not exactly the same, and there is a non-empty intersection between the frequency domain position of candidate BWP1 and the frequency domain position of candidate BWP2, there is a non-empty intersection between the frequency domain position of candidate BWP4 and the frequency domain position of candidate BWP3, and there is a non-empty intersection between the frequency domain position of candidate BWP4 and the frequency domain position of candidate BWP5.
[0146] In another possible implementation, two adjacent BWPs among the aforementioned N candidate BWPs may not have a non-empty intersection. Figure 5B For example, the first candidate BWP set may include 5 candidate BWPs, wherein the number of RBs occupied by the 5 candidate BWPs is not completely the same, and the frequency domain positions of every two adjacent BWPs in the 5 candidate BWPs do not have any intersection.
[0147] It should be understood that Figure 5B There may also be idle RBs between two of the five candidate BWPs shown, which is not limited here. It should be understood that in practical applications, the first candidate BWP set can be implemented using any of the aforementioned implementations, which is not limited here. In the following description, only the example of the absence of a non-empty intersection between two adjacent BWPs in the aforementioned N candidate BWPs is used for introduction.
[0148] In this embodiment, the first candidate BWP set may be pre-configured by operation and maintenance personnel, or may be determined by the network device based on a preset rule.
[0149] In a possible implementation, if the first candidate BWP set is determined by the network device based on a preset rule, the network device may determine the first candidate BWP set based on the type information of the terminal device in the first cell and the system bandwidth of the first cell. The type information of the terminal device is used to indicate the ratio of the number of different types of terminal devices in the first cell, and the maximum system bandwidth supported by the different types of terminal devices is different. It should be understood that the type information of the terminal device in the first cell is determined based on the terminal devices that accessed the first cell within a certain period of time in history.
[0150] Exemplarily, the type information of the terminal devices in the first cell may indicate that the first cell includes terminal devices supporting a maximum system bandwidth of 20M (hereinafter referred to as first type of terminal devices) and terminal devices supporting a maximum system bandwidth greater than 20M (hereinafter referred to as second type of terminal devices), and 80% are first type of terminal devices and 20% are second type of terminal devices. If the system bandwidth of the first cell is 90M, the network device may set multiple candidate BWPs, and the union of the frequency domain positions of the multiple candidate BWPs is 90M. For example, Figure 5C As shown, the first candidate BWP set includes three 20M candidate BWPs and one 30M candidate BWP. Figure 5C The four candidate BWPs can also be arranged in other orders on the system bandwidth. For example, candidate BWP4 with a bandwidth of 30M is located near the center frequency point of the system bandwidth, and the aforementioned 20M candidate BWPs (i.e., candidate BWP1, candidate BWP2, and candidate BWP3) are arranged at other positions on the system bandwidth.
[0151] Step 402: The network device selects a candidate BWP from a first candidate BWP set as an initial BWP, and configures the initial BWP for a terminal device in a first cell.
[0152] Optionally, the network device uses the frequency domain position of a BWP with a bandwidth less than or equal to 20M from the first candidate BWP set as the initial BWP. That is, the frequency domain position of the initial BWP is the same as the frequency domain position of one of the N candidate BWPs. Figure 5C For example, the initial BWP may be candidate BWP1, candidate BWP2 or candidate BWP3. The following description will take the initial BWP as candidate BWP3 as an example.
[0153] It should be understood that the initial BWP is a cell-level BWP configured by the network device. The initial BWP may be configured through the first system information block SIB1, or the initial BWP may be determined by CORESET0, which is not specifically limited here.
[0154] Step 403: The network device sends first configuration information to the first terminal device, where the first configuration information is used to configure a first dedicated BWP for the first terminal device; accordingly, the first terminal device receives the first configuration information from the network device.
[0155] The first terminal device is a terminal device located in a first cell, and the first cell may include a plurality of the aforementioned first terminal devices. The first cell is a cell under a network device, and the system bandwidth of the first cell is greater than (or much greater than) the maximum system bandwidth supported by some terminal devices in the first cell. The first cell includes multiple types of terminal devices, and each type of terminal device supports a different maximum system bandwidth.
[0156] In addition, the first configuration information is used to configure a first dedicated BWP for the first terminal device, and the frequency domain position of the first dedicated BWP is the same as the frequency domain position of the initial BWP of the first cell. Specifically, it can be understood that the first dedicated BWP has the same starting RB and the number of occupied RBs as the initial BWP. Figure 5CFor example, if the initial BWP is candidate BWP3, the first dedicated BWP is also located at Figure 5C The frequency domain position of the candidate BWP3.
[0157] It should be understood that in this embodiment, the introduction of terms such as the initial BWP, the first cell, the first terminal device and the first dedicated BWP can be specifically referred to the relevant description in the previous step 201, which will not be repeated here.
[0158] Step 404: The first terminal device sends the capability information of the first terminal device to the network device through the first dedicated BWP; correspondingly, the network device receives the capability information of the first terminal device through the first dedicated BWP.
[0159] The capability information of the first terminal device includes the maximum system bandwidth supported by the first terminal device. Optionally, the capability information of the first terminal device may also include the amount of resources required by the first terminal device to transmit services.
[0160] In addition, the capability information of the first terminal device also includes first capability information, and the first capability information is used to indicate that the first terminal device supports the first capability, that is, indicates that the first terminal device supports the capability of BWP without restrictions. Specifically, the first capability information is used to indicate that the first terminal device supports the BWP_WithOutRestirction capability, that is, the first terminal device supports BWP operation without bandwidth restrictions. It can also be understood that the first terminal device can use a dedicated BWP that does not include an initial BWP or SSB to send service data to a network device.
[0161] When the capability information of the first terminal device includes the first capability information, the network device will execute step 405.
[0162] Step 405: When the first terminal device supports the first capability, the network device selects another candidate BWP from the first candidate BWP set as the second dedicated BWP.
[0163] Optionally, the network device selects another candidate BWP (i.e., a candidate BWP that is not the initial BWP) from the first candidate BWP set as the second dedicated BWP. Since the frequency domain positions of the candidate BWPs in the first candidate BWP set are different, the frequency domain position of the second dedicated BWP is different from the frequency domain position of the initial BWP. Since the frequency domain position of the first dedicated BWP is the same as the frequency domain position of the initial BWP, the frequency domain position of the second dedicated BWP is different from the frequency domain position of the first dedicated BWP. Optionally, the intersection of the frequency domain position of the second dedicated BWP and the frequency domain position of the initial BWP is empty. Still using the aforementioned Figure 5C For example, if the initial BWP is candidate BWP3, the first dedicated BWP is also located at Figure 5C At this time, the second dedicated BWP may be any one of the candidate BWP1, the candidate BWP2 and the candidate BWP4.
[0164] Optionally, if the first terminal device carries the maximum system bandwidth supported by the first terminal device in the capability information of the first terminal device sent to the network device, the network device will select a candidate BWP for the first terminal device as the second dedicated BWP with reference to the maximum system bandwidth supported by the first terminal device. Exemplarily, if the capability information of the first terminal device indicates that the maximum system bandwidth supported by the first terminal device is 30M, the network device will determine Figure 5C The candidate BWP4 in the example shown is used as the second dedicated BWP; if the capability information of the first terminal device indicates that the maximum system bandwidth supported by the first terminal device is 20M, the network device will determine Figure 5C The candidate BWP1 or the candidate BWP2 in the illustrated example serves as the second dedicated BWP.
[0165] It should be understood that the network device may also consider load balancing when determining the second dedicated BWP for the first terminal device. For example, if the capability information of the first terminal device indicates that the maximum system bandwidth supported by the first terminal device is 20M, and multiple terminal devices are already connected to the candidate BWP1, while there are fewer terminal devices on the candidate BWP2, the network device will determine Figure 5C Candidate BWP2 in the illustrated example serves as the second dedicated BWP.
[0166] Step 406: The network device sends second configuration information to the first terminal device, where the second configuration information is used to configure a second dedicated BWP for the first terminal device; accordingly, the first terminal device receives the second configuration information from the network device.
[0167] The second dedicated BWP is used to transmit the service data of the first terminal device. That is to say, after the first terminal device receives the aforementioned second configuration information, the first terminal device can determine the frequency domain position of the second dedicated BWP. In addition, if the first terminal device needs to transmit service data, the first terminal device will send the service data to the network device through the second dedicated BWP.
[0168] It should be understood that the network device can send the second configuration information to the first terminal device in a variety of ways. In one possible implementation, the network device can carry the second configuration information in the dedicated signaling of the first terminal device. For example, the network device can send the aforementioned second configuration information to the first terminal device via dedicated radio resource control RRC signaling, so that the first terminal device can obtain the second configuration information from the RRC signaling. Optionally, the network device can carry the second configuration information in the downlink control information DCI, which is not specifically limited here.
[0169] Step 407: The network device sends third configuration information to the first terminal device, where the third configuration information is used to configure the frequency domain position of the PUCCH in the second dedicated BWP; accordingly, the first terminal device receives the third configuration information from the network device.
[0170] Specifically, the third configuration information is used to configure the frequency domain position of the physical uplink control channel PUCCH in the second dedicated BWP to be adjacent to the frequency domain position of the PUCCH in the first dedicated BWP. Exemplarily, the third configuration information is information used to indicate the frequency domain position of the PUCCH in the second dedicated BWP, for example, the code channel number of the PUCCH of the second dedicated BWP. Since the frequency domain position of the PUCCH in the second dedicated BWP is adjacent to the frequency domain position of the PUCCH in the first dedicated BWP, the discontinuous scheduling frequency of the physical uplink shared channel PUSCH caused by PUCCH isolation can be reduced, which is conducive to improving the utilization efficiency of frequency domain resources.
[0171] Optionally, the PUCCH configured by the third configuration information is a dedicated PUCCH, which is mainly used to receive ACK feedback corresponding to the downlink physical shared channel PDSCH after the terminal device (for example, the first terminal device) accesses, and to report channel state information (CSI) and reference signal (RS) related information to the network device.
[0172] In this embodiment, since there are multiple possible implementations of the frequency domain position of the first dedicated BWP and the frequency domain position of the second dedicated BWP, there are also multiple possible implementations of the frequency domain position of the PUCCH in the second dedicated BWP, which are described below respectively:
[0173] In a possible implementation, Fig. 6AAs shown, when the frequency domain position of the first dedicated BWP is adjacent to the frequency domain position of the second dedicated BWP, the PUCCH in the second dedicated BWP is located on one side of the PUCCH close to the first dedicated BWP. Specifically, one side of the PUCCH in the second dedicated BWP is the PUCCH in the first dedicated BWP, and the other side is the PUSCH in the second dedicated BWP. Therefore, the PUSCH in the second dedicated BWP is continuous and will not be interrupted by the PUCCH in the first dedicated BWP.
[0174] In another possible implementation, when the frequency domain position of the first dedicated BWP and the frequency domain position of the second dedicated BWP have a non-empty intersection, part or all of the PUCCHs in the second dedicated BWP are located in the non-empty intersection.
[0175] like Figure 6B As shown in FIG. 1 , when the amount of resources occupied by the non-empty intersection of the first dedicated BWP and the second dedicated BWP is greater than or equal to the amount of resources occupied by the PUCCH of the second dedicated BWP, all PUCCHs in the second dedicated BWP are located in the non-empty intersection. Specifically, one side of the PUCCH in the second dedicated BWP is the PUCCH in the first dedicated BWP, and the other side is the PUSCH in the first dedicated BWP. Therefore, the PUSCH in the second dedicated BWP is continuous and will not be interrupted by the PUCCH in the first dedicated BWP.
[0176] like Figure 6C As shown in FIG. 1 , when the amount of resources occupied by the non-empty intersection of the first dedicated BWP and the second dedicated BWP is less than the amount of resources occupied by the PUCCH of the second dedicated BWP, part of the PUCCH in the second dedicated BWP is located in the non-empty intersection. At this time, both sides of the PUCCH of the first dedicated BWP close to the second dedicated BWP are the PUCCH of the second dedicated BWP. Therefore, the PUSCH in the second dedicated BWP is continuous and will not be interrupted by the PUCCH in the first dedicated BWP.
[0177] It should be understood that in this embodiment, there is no clear time sequence limitation for step 406 and step 407, the network device may first execute step 406 and then step 407, the network device may first execute step 407 and then step 406, or the network device may first execute step 407 and then step 406. In particular, the network device may also carry the second configuration information and the third configuration information in a certain RRC signaling so as to send it to the first terminal device. This embodiment is not limited in detail.
[0178] Step 408: The first terminal device transmits service data via the second dedicated BWP.
[0179] In this embodiment, the network device can select a candidate BWP from a predetermined first candidate BWP set as the initial BWP and configure the frequency domain position of the first dedicated BWP to be the same as the frequency domain position of the initial BWP. Then, the first terminal device uploads the capability information of the first terminal device to the network device through the first dedicated BWP, so that after the network device learns that the first terminal device supports the first capability (i.e., the capability to support BWP without restrictions), it selects another candidate BWP (i.e., a candidate BWP other than the initial BWP) from the first candidate BWP set based on the capability information of the first terminal device as the second dedicated BWP, and the second dedicated BWP is used to transmit service data. Therefore, the first terminal device does not need to be concentrated on the initial BWP with other terminal devices, but can be located at other frequency domain positions in the system bandwidth, which is conducive to improving the utilization of the system bandwidth. In addition, when the bandwidth size of the second dedicated BWP is the maximum system bandwidth supported by the first terminal device, it is not only conducive to improving the utilization of the system bandwidth, but also conducive to ensuring the efficiency of the first terminal device in transmitting service data. In addition, the network device can also configure the PUCCH of the second dedicated BWP to be adjacent to the PUCCH of the first dedicated BWP to avoid the PUSCH of the second dedicated BWP being interrupted due to the non-empty intersection of the frequency domain position of the first dedicated BWP and the frequency domain position of the second dedicated BWP, so that the PUSCH in the second dedicated BWP is continuous, which is conducive to improving resource utilization.

[0206] Optionally, the terminal devices in the first cell include terminal devices of a first type and terminal devices of a second type, the maximum system bandwidth supported by the terminal devices of the first type is smaller than the maximum system bandwidth supported by the terminal devices of the second type, the system bandwidth of the first cell is larger than the maximum system bandwidth supported by the terminal devices of the first type, and the first terminal device belongs to the terminal device of the first type or to the terminal device of the second type.

[0209] Optionally, the bandwidth of the second dedicated BWP is the maximum system bandwidth supported by the first terminal device.
[0210] In a possible implementation, the communication device 80 is used to perform the aforementioned Figure 4 The method in the corresponding embodiment. The processor 801 in the communication device 80 is used to control the transceiver 803 to receive third configuration information from the network device, and the third configuration information is used to configure the frequency domain position of the physical uplink control channel PUCCH in the second dedicated BWP to be adjacent to the frequency domain position of the PUCCH in the first dedicated BWP.
[0211] Optionally, when the frequency domain position of the first dedicated BWP is adjacent to the frequency domain position of the second dedicated BWP, the PUCCH in the second dedicated BWP is located on the side of the PUCCH close to the first dedicated BWP; when the frequency domain position of the first dedicated BWP has a non-empty intersection with the frequency domain position of the second dedicated BWP, part or all of the PUCCH in the second dedicated BWP is located in the non-empty intersection.
[0212] Optionally, the intersection of the frequency domain position of the second dedicated BWP and the frequency domain position of the initial BWP is empty.
[0213] For the rest, reference may be made to the method of the terminal device in the above embodiment, which will not be described in detail here.
[0214] like Fig. 9 As shown, the present application also provides another communication device 90, which can be a network device or a chip in a network device. Optionally, the network device is an access network device. The communication device 90 includes: a transceiver module 901 and a processing module 902.
[0215] Specifically, the transceiver module 901 is used to send first configuration information to a first terminal device located in a first cell, and the first configuration information is used to configure a first dedicated BWP for the first terminal device. The transceiver module 901 is also used to receive capability information of the first terminal device through the first dedicated BWP. The processing module 902 parses the capability information of the first terminal device, and when the first terminal device supports the first capability, controls the transceiver module 901 to send second configuration information to the first terminal device, and the second configuration information is used to configure a second dedicated BWP for the first terminal device, and the second dedicated BWP is used to transmit the service data of the first terminal device, and the first capability is the capability of the first terminal device to support BWP without restriction.
[0216] The frequency domain position of the first dedicated BWP is the same as the frequency domain position of the initial BWP of the first cell, and the frequency domain position of the second dedicated BWP is different from the frequency domain position of the initial BWP.
[0217] Since the communication device 90 configures a BWP (i.e., a first dedicated BWP) with the same frequency domain position as the initial BWP for the first terminal device to report the capability information of the first terminal device, and after learning that the first terminal device supports the first capability (i.e., the capability to support BWP without restrictions), a BWP with a frequency domain position different from the initial BWP is configured for the first terminal device to transmit service data. Therefore, the first terminal device does not need to be concentrated on the initial BWP with other terminal devices, but can be located at other frequency domain positions in the system bandwidth, which is conducive to improving the utilization rate of the system bandwidth.
[0218] In a possible implementation, the terminal devices in the first cell include terminal devices of a first type and terminal devices of a second type, the maximum system bandwidth supported by the terminal devices of the first type is smaller than the maximum system bandwidth supported by the terminal devices of the second type, the system bandwidth of the first cell is larger than the maximum system bandwidth supported by the terminal devices of the first type, and the first terminal device belongs to the terminal device of the first type or to the terminal device of the second type.
[0219] Exemplarily, the first type of terminal device is an LTE terminal device, and the second type of terminal device is an NR terminal device (or a 6G terminal device). Since the maximum system bandwidth supported by the LTE terminal device is 20M, and the maximum system bandwidth supported by the NR terminal device (or a 6G terminal device) is greater than 20M, the system bandwidth of the first cell in this example is at least greater than 20M.
[0220] In a possible implementation manner, the bandwidth of the initial BWP is less than or equal to the maximum system bandwidth supported by the first type of terminal equipment.
[0221] In this embodiment, it is proposed that the bandwidth of the initial BWP of the first cell needs to be less than or equal to the maximum system bandwidth supported by the terminal device with a smaller bandwidth in the first cell, so as to ensure that the terminal devices in the first cell can access the first cell through the initial BWP. Exemplarily, if there are terminal devices supporting a maximum system bandwidth of 20M (referred to as 20M terminal devices), terminal devices supporting a maximum system bandwidth of 30M (referred to as 30M terminal devices), and terminal devices supporting a maximum system bandwidth of 50M (referred to as 50M terminal devices) in the first cell, the size of the initial BWP of the first cell needs to be less than or equal to 20M.
[0222] In addition, since the frequency domain position of the first dedicated BWP is the same as the frequency domain position of the initial BWP of the first cell, if the first terminal device can access the initial BWP, then the first terminal device can also access the first dedicated BWP. Therefore, it is beneficial to improve the success rate of the first terminal device accessing the cell.
[0223] In a possible implementation manner, the maximum system bandwidth supported by the first type of terminal equipment is 20M.
[0224] In a possible implementation manner, the bandwidth of the second dedicated BWP is the maximum system bandwidth supported by the first terminal device.
[0225] In this embodiment, if the capability information of the first terminal device reported to the network device by the first terminal device through the first dedicated BWP includes the maximum system bandwidth supported by the first terminal device, the size of the second dedicated BWP configured by the network device for the first terminal device may be equal to the maximum system bandwidth supported by the first terminal device. In this case, it is not only beneficial to improve the utilization rate of the system bandwidth, but also beneficial to ensure the efficiency of the first terminal device in transmitting service data.
[0226] In a possible implementation, the network device stores a first candidate BWP set, the first candidate BWP set includes N candidate BWPs, the frequency domain positions of the N candidate BWPs are different, the union of the frequency domain positions of the N candidate BWPs is equal to the frequency domain position of the system bandwidth of the first cell, and N is an integer greater than 1. The frequency domain position of the initial BWP is the same as the frequency domain position of one of the N candidate BWPs, and the frequency domain position of the second dedicated BWP is the same as the frequency domain position of another of the N candidate BWPs.
[0227] It should be understood that there may be a non-empty intersection between the frequency domain positions of two adjacent BWPs in the aforementioned N candidate BWPs, or there may not be a non-empty intersection, which is not specifically limited here.
[0228] In this embodiment, it is proposed that a candidate BWP set (i.e., a first candidate BWP set) is stored in the network device, and the network device can directly select BWPs located at different frequency domain positions from the first candidate BWP set as the initial BWP and the second dedicated BWP. In addition, the N candidate BWPs in the first candidate BWP set can cover the entire system bandwidth. If the network device configures different terminal devices in the first cell in the N candidate BWPs according to the aforementioned first candidate BWP set, the terminal devices in the first cell can be distributed more evenly on the system bandwidth, rather than being concentrated in a certain frequency domain position.
[0229] In one possible implementation, the processing module is also used to determine the first candidate BWP set based on the type information of the terminal device in the first cell and the system bandwidth of the first cell; wherein the type information of the terminal device is used to indicate the ratio of the number of different types of terminal devices in the first cell, and the maximum system bandwidths supported by the different types of terminal devices are different.
[0230] In this implementation, it is proposed that the first candidate BWP set may be determined by the network device based on a preset rule, for example, the network device determines the first candidate BWP set based on the type information of the terminal device in the first cell and the system bandwidth of the first cell. It should be understood that the type information of the terminal device in the first cell is determined based on the terminal devices accessing the first cell within a certain period of time in history.
[0231] In a possible implementation, the transceiver module is also used to send third configuration information to the first terminal device, and the third configuration information is used to configure the frequency domain position of the physical uplink control channel PUCCH in the second dedicated BWP to be adjacent to the frequency domain position of the PUCCH in the first dedicated BWP.
[0232] Exemplarily, the third configuration information is information for indicating the frequency domain position of the PUCCH in the second dedicated BWP, for example, the code channel number of the PUCCH of the second dedicated BWP. Since the frequency domain position of the PUCCH in the second dedicated BWP is adjacent to the frequency domain position of the PUCCH in the first dedicated BWP, the discontinuous scheduling frequency of the physical uplink shared channel PUSCH caused by the PUCCH cutoff can be reduced, which is conducive to improving the utilization efficiency of frequency domain resources.
[0233] Optionally, the PUCCH configured by the third configuration information is a dedicated PUCCH, which is mainly used to receive ACK feedback corresponding to the downlink physical shared channel PDSCH after the terminal device (for example, the first terminal device) accesses, and to report relevant information of channel state information CSI and reference signal RS to the network device.
[0234] In a possible implementation manner, when the frequency domain position of the first dedicated BWP is adjacent to the frequency domain position of the second dedicated BWP, the PUCCH in the second dedicated BWP is located on a side close to the PUCCH of the first dedicated BWP;
[0235] When the frequency domain position of the first dedicated BWP and the frequency domain position of the second dedicated BWP have a non-empty intersection, part or all of the PUCCHs in the second dedicated BWP are located in the non-empty intersection.
[0236] In a possible implementation manner, the intersection of the frequency domain position of the second dedicated BWP and the frequency domain position of the initial BWP is empty.
[0237] For the rest, reference may be made to the method of the network device in the above embodiment, which will not be described in detail here.
[0238] like Fig.10 As shown, the present application also provides another communication device 100 , which may be a terminal device or a chip in the terminal device. The communication device 100 includes: a transceiver module 1001 and a processing module 1002 .
[0239] Among them, the transceiver module 1001 in the communication device 100 is used to receive first configuration information from the network device, and the first configuration information is used to configure the first dedicated BWP for the first terminal device. The processing module 1002 is used to configure the first dedicated BWP according to the first configuration information. The transceiver module 1001 is also used to send the capability information of the first terminal device to the network device through the first dedicated BWP, and the capability information of the first terminal device includes the first capability information, and the first capability information is used to indicate that the first terminal device supports the capability of BWP without restriction. The transceiver module 1001 is also used for the first terminal device to receive second configuration information from the network device, and the second configuration information is used to configure the second dedicated BWP for the first terminal device, the frequency domain position of the second dedicated BWP is different from the frequency domain position of the initial BWP, and the second dedicated BWP is used to transmit the service data of the first terminal device. The processing module 1002 is used to configure the second dedicated BWP according to the second configuration information.
[0240] The frequency domain position of the first dedicated BWP is the same as the frequency domain position of the initial BWP of the first cell, and the frequency domain position of the second dedicated BWP is different from the frequency domain position of the initial BWP.
[0241] Since the communication device 100 configures a BWP (i.e., a first dedicated BWP) with the same frequency domain position as the initial BWP for the first terminal device to report the capability information of the first terminal device, and after learning that the first terminal device supports the first capability (i.e., the capability of supporting BWP without restrictions), a BWP with a frequency domain position different from the initial BWP is configured for the first terminal device for transmitting service data. Therefore, the first terminal device does not need to be concentrated on the initial BWP with other terminal devices, but can be located at other frequency domain positions in the system bandwidth, which is conducive to improving the utilization rate of the system bandwidth.
[0242] In a possible implementation, the terminal devices in the first cell include terminal devices of a first type and terminal devices of a second type, the maximum system bandwidth supported by the terminal devices of the first type is smaller than the maximum system bandwidth supported by the terminal devices of the second type, the system bandwidth of the first cell is larger than the maximum system bandwidth supported by the terminal devices of the first type, and the communication device 100 belongs to the terminal devices of the first type or to the terminal devices of the second type.
[0243] In a possible implementation manner, the bandwidth of the initial BWP is less than or equal to the maximum system bandwidth supported by the first type of terminal equipment.
[0244] In this embodiment, it is proposed that the bandwidth of the initial BWP of the first cell needs to be less than or equal to the maximum system bandwidth supported by the terminal device with a smaller bandwidth in the first cell, so as to ensure that the terminal devices in the first cell can access the first cell through the initial BWP. Exemplarily, if there are terminal devices supporting a maximum system bandwidth of 20M (referred to as 20M terminal devices), terminal devices supporting a maximum system bandwidth of 30M (referred to as 30M terminal devices), and terminal devices supporting a maximum system bandwidth of 50M (referred to as 50M terminal devices) in the first cell, the size of the initial BWP of the first cell needs to be less than or equal to 20M.
[0245] In addition, since the frequency domain position of the first dedicated BWP is the same as the frequency domain position of the initial BWP of the first cell, if the first terminal device can access the initial BWP, then the first terminal device can also access the first dedicated BWP. Therefore, it is helpful to improve the success rate of the first terminal device accessing the cell.
[0246] In a possible implementation manner, the maximum system bandwidth supported by the first type of terminal equipment is 20M.
[0247] In a possible implementation manner, the bandwidth of the second dedicated BWP is the maximum system bandwidth supported by the first terminal device.
[0248] In this embodiment, if the capability information of the first terminal device reported to the network device by the first terminal device through the first dedicated BWP includes the maximum system bandwidth supported by the first terminal device, the size of the second dedicated BWP configured by the network device for the first terminal device may be equal to the maximum system bandwidth supported by the first terminal device. In this case, it is not only beneficial to improve the utilization rate of the system bandwidth, but also beneficial to ensure the efficiency of the first terminal device in transmitting service data.
[0249] In a possible implementation, the transceiver module is further used to receive third configuration information from the network device, and the third configuration information is used to configure the frequency domain position of the physical uplink control channel PUCCH in the second dedicated BWP to be adjacent to the frequency domain position of the PUCCH in the first dedicated BWP.
[0250] Exemplarily, the third configuration information is information for indicating the frequency domain position of the PUCCH in the second dedicated BWP, for example, the code channel number of the PUCCH of the second dedicated BWP. Since the frequency domain position of the PUCCH in the second dedicated BWP is adjacent to the frequency domain position of the PUCCH in the first dedicated BWP, the discontinuous scheduling frequency of the physical uplink shared channel PUSCH caused by the PUCCH cutoff can be reduced, which is conducive to improving the utilization efficiency of frequency domain resources.
[0251] Optionally, the PUCCH configured by the third configuration information is a dedicated PUCCH, which is mainly used to receive ACK feedback corresponding to the downlink physical shared channel PDSCH after the terminal device (for example, the first terminal device) accesses, and to report relevant information of channel state information CSI and reference signal RS to the network device.
[0252] In a possible implementation, when the frequency domain position of the first dedicated BWP is adjacent to the frequency domain position of the second dedicated BWP, the PUCCH in the second dedicated BWP is located on the side close to the PUCCH of the first dedicated BWP; when the frequency domain position of the first dedicated BWP and the frequency domain position of the second dedicated BWP have a non-empty intersection, part or all of the PUCCH in the second dedicated BWP is located in the non-empty intersection.
[0253] In a possible implementation manner, the intersection of the frequency domain position of the second dedicated BWP and the frequency domain position of the initial BWP is empty.
