[0029] It will be understood that the functions, steps, etc. shown in this disclosure may occur in an order different from that shown in this disclosure without conflict.

[0030] The following is an introduction to the technical terms involved in the embodiments of the present disclosure.

[0031] Radio Resource Control (RRC) is a key protocol layer in wireless communication systems, primarily responsible for managing radio resources between user equipment (UE) and base stations. The RRC protocol resides in the control plane and handles signaling and messages related to radio resource management.

[0032] RRC state is an important concept that describes the connection status between the UE and the network. Generally, the UE can be in one of three RRC states: idle state (RRC_IDLE), connected state (RRC_CONNECTED) and inactive state (RRC_INACTIVE).

[0033] In the RRC_IDLE state, there is no connection between the UE and the network, but the UE can receive broadcast system information and paging messages. In the RRC_CONNECTED state, a connection is established between the UE and the network, and data transmission and reception services can be performed. In the RRC_INACTIVE state, a connection is established between the UE and the network, but data transmission and reception services cannot be performed.

[0034] 2. BWP, a new concept introduced in 5G NR, is a subset of the entire bandwidth. In 5G NR, BWP is used to support operations with different bandwidths and carrier aggregation, allowing UEs to operate on specific time or frequency domain resources, thereby achieving more efficient and flexible spectrum utilization.

[0035] The size of the BWP, as well as its subcarrier spacing (SCS) and cyclic prefix (CP), can be flexibly configured. The introduction of the BWP is primarily intended to address the high power consumption associated with large bandwidths in 5G, reducing power consumption by flexibly adjusting the transmit and receive bandwidths of the UE.

[0036] BWP can be divided into the following types:

[0037] Initial BWP: This is the BWP used by the UE during initial access, primarily for receiving System Information Block (SIB) and Random Access (RA) information. The initial BWP is typically used in Idle state and is typically smaller than the BWP in Connected state.

[0038] Dedicated BWP: This is the BWP configured by the UE in RRC connected state. Each UE can be configured with up to four dedicated BWPs on each carrier. Dedicated BWP can be used for data transmission and reception and PDCCH (Physical Downlink Control Channel) monitoring.

[0039] Active BWP: This is the BWP that the UE activates at a certain moment in the RRC connected state. Only one dedicated BWP can be activated at a time. The active BWP is the BWP that the UE is currently using.

[0040] The default BWP is the default BWP used by the UE. For example, if no dedicated BWP is configured, the initial BWP is considered the default BWP. After the bwp-inactivityTimer (a timer used to manage the UE's activity status in a specific BWP) expires, if the UE is still not scheduled, the UE is switched to the default BWP.

[0041] In 5G networks, the configuration of various RRC signaling on the BWP is a key process. RRC signaling is mainly used to configure and control radio resources, including the configuration of the BWP. The following is some basic information about the RRC signaling configuration on the BWP:

[0042] BWP identity (BWP-Id): Each BWP has a unique identifier, called BWP-Id. BWP-Id can be used to identify and associate a specific BWP. Typically, the initial BWP is identified by BWP-Id = 0.

[0043] RRC configuration: RRC configuration is used to configure and control the radio resources of the UE.

[0044] Exemplarily, the RRC configuration may include at least one of the following: information about the BWP itself (such as frequency domain position, BWP bandwidth, etc.), monitoring information of the physical downlink control channel (PDCCH) corresponding to the BWP, channel information corresponding to the BWP (for example, physical downlink shared channel (PDSCH), physical uplink shared channel (PUSCH), physical uplink control channel (PUCCH), physical random access channel (PRACH)), downlink signal configuration or uplink signal configuration corresponding to the BWP, and measurement information corresponding to the BWP (for example, channel state information (CSI) measurement, radio resource management (RRM) measurement).

[0045] Downlink Control Information (DCI) and BWP mapping: There are 4 code points in DCI, which are mapped to up to four BWPs configured by RRC, from 0 to 3. This means that DCI can instruct the UE to activate or switch to a specific BWP.

[0046] BWP common configuration (bwp-Common): includes some common parameters applicable to all BWPs.

[0047] BWP-Dedicated configuration: includes some parameters that apply only to a specific BWP.

[0048] Downlink BWP (BWP-Downlink) configuration: includes BWP downlink configuration parameters.

[0049] Exemplarily, BWP-Downlink may include at least one of the following: bwp-Common, for example, BWP-DownlinkCommon; and bwp-Dedicated information element (IE), for example, BWP-DownlinkDedicated IE. The IE includes the common configuration and dedicated configuration of the BWP.

[0050] Configuration process: When the UE is in the RRC connected state, the network can configure or reconfigure the BWP through RRC signaling. For example, the network can send an RRC reconfiguration message including new BWP information to update or modify the UE's BWP configuration.

[0051] The above is an explanation of the technical terms involved in the embodiments of the present disclosure, which will not be repeated below.

[0052] Mobile communications have continued to evolve at a rate of one generation of technology every ten years, progressing through the 1G, 2G, 3G, 4G, and 5G generations. Each generational leap and each technological advancement has significantly contributed to industrial upgrading and economic and social development. From 1G to 2G, analog to digital communications transitioned, bringing mobile communications into every household. From 2G to 3G, 4G, and 5G, voice services transitioned to data services, increasing transmission rates by a hundredfold and promoting the widespread adoption and prosperity of mobile internet applications. With the rapid development of the mobile internet, new services, new businesses, new technologies, and new devices are constantly emerging. 5G mobile communications systems are unable to meet the future demands for flexible and diverse services, necessitating the urgent need to develop next-generation mobile communications systems (6G).

[0053] 6G (sixth generation) is a conceptual wireless network mobile communication technology, also known as the sixth-generation mobile communication standard or sixth-generation mobile communication technology. The design of the 6G system is currently in the candidate technology solicitation phase, and no detailed design plan for the 6G system has been released. As a brand-new system, 6G will support new services such as perception, intelligence, and computing power. How to design and implement flexible information configuration within this system to adapt to different service needs and channel changes requires research and solution.

[0054] If there is no solution for configuring a terminal-specific BWP in a non-connected state, terminal-specific scheduling and configuration cannot be achieved in a non-connected state, which limits configuration flexibility and affects network performance.

[0055] If BWP is defined based on a cell, when the terminal cell switches, the corresponding BWP also needs to switch with the cell, which will bring additional switching signaling overhead and terminal power consumption, affecting the continuity of service transmission.

[0056] In the future, multiple physical cells may be aggregated into a regional-level cell, or the cell definition will be UE-centric, or distributed antennas will be deployed on a large scale, and terminals will switch between these distributed antennas. The cell-based BWP definition method will no longer be applicable. A new BWP definition method needs to be introduced to solve the above problems, improve the flexibility of BWP configuration, and adapt to new scenarios and new technologies.

[0057] To address the above technical issues, embodiments of the present disclosure provide an information transmission method, which comprises: receiving first signaling including configuration information for a bandwidth part (BWP); the BWP being a BWP used by the first node in a non-connected state; and utilizing the BWP based on the BWP configuration information. As can be seen, embodiments of the present disclosure configure a BWP capable of resident in a non-connected state, improving BWP configuration flexibility, enhancing network performance, and adapting to new scenarios and technologies.

[0058] The technical solutions provided by the embodiments of the present disclosure can be applied to various mobile communication systems, for example, NR mobile communication systems using 5G, future mobile communication systems, or systems that integrate multiple communications, etc., and the embodiments of the present disclosure are not limited to this.

[0059] The network architecture of the mobile communication system (including but not limited to 3G, 4G, 5G, 6G and future mobile communication systems) in the embodiment of the present disclosure may include at least a first communication node and a second communication node. It should be understood that in this example, in the uplink, the first communication node may be a terminal side device (for example, including but not limited to a terminal), and the second communication node may be a network side device (for example, including but not limited to a base station). Of course, in the downlink, the first communication node may also be a network side device, and the second communication node may also be a terminal side device. In the device-to-device communication between the two communication nodes, the first communication node and the second communication node may both be base stations or terminals. For ease of description, the first communication node may be described as a first node, and the second communication node may be described as a second node.

[0060] For example, taking the first node as a terminal and the second node as a base station as an example, FIG1 shows a schematic diagram of the architecture of a mobile communication system provided by an embodiment of the present disclosure. As shown in FIG1 , the mobile communication system includes a terminal 110 and a base station 120.

[0061] In some embodiments, the terminal 110 can be a device with wireless transceiver capabilities, which can be deployed on land, including indoors or outdoors, handheld, wearable, or vehicle-mounted; it can also be deployed on the water (such as a ship, etc.); it can also be deployed in the air (for example, on an airplane, a balloon, and a satellite, etc.). The terminal can be a mobile phone, a tablet computer, a computer with wireless transceiver capabilities, a virtual reality (VR) terminal, an augmented reality (AR) terminal, a wireless terminal in industrial control, a wireless terminal in self-driving, a wireless terminal in remote medical care, a wireless terminal in a smart grid, a wireless terminal in transportation safety, a wireless terminal in a smart city, a wireless terminal in a smart home, etc. The embodiments of the present disclosure do not limit the application scenarios. The terminal may sometimes also be referred to as a user, UE, access terminal, UE unit, UE station, mobile station, mobile station, remote station, remote terminal, mobile device, UE terminal, wireless communication device, UE agent or UE device, etc., which is not limited in the embodiments of the present disclosure.

[0062] In some embodiments, base station 120 is configured to provide wireless access services to multiple terminals 110. For example, a base station provides a service coverage area (also referred to as a cell). Terminals 110 that enter this area can communicate with base station 120 via wireless signals to receive the wireless access services provided by base station 120.

[0063] In some embodiments, the base station 120 can be a base station or an evolved base station (eNB or eNodeB) in long term evolution (LTE), long term evolution advanced (LTEA), a base station device in a 5G network, or a base station in a future communication system, etc. The base station can include various macro base stations, micro base stations, home base stations, wireless remote stations, reconfigurable intelligent surfaces (RIS), routers, wireless fidelity (WIFI) devices and other network side devices.

[0064] It should be noted that Figure 1 is only an exemplary framework diagram. The number of devices included in Figure 1 and the names of each device are not restricted. In addition to the devices shown in Figure 1, the communication system may also include other devices, such as core network devices.

[0065] The application scenarios of the embodiments of the present disclosure are not limited. The system architecture and business scenarios described in the embodiments of the present disclosure are intended to more clearly illustrate the technical solutions of the embodiments of the present disclosure and do not constitute a limitation on the technical solutions provided by the embodiments of the present disclosure. Those skilled in the art will appreciate that with the evolution of network architecture and the emergence of new business scenarios, the technical solutions provided by the embodiments of the present disclosure are equally applicable to similar technical problems.

[0066] The following is an exemplary introduction to the information transmission method provided by the embodiment of the present disclosure.

[0067] The present disclosure provides an information transmission method, which is applied to the mobile communication system shown in FIG1 (for ease of description, the first node is described below as a terminal and the second node is described as a base station).

[0068] As shown in FIG2 , the information transmission method provided by the embodiment of the present disclosure includes the following steps S201 - S202 .

[0069] S201. A second node sends a first signaling to a first node; correspondingly, the first node receives the first signaling.

[0070] The first signaling includes BWP configuration information. Exemplarily, the first signaling includes at least one of the following: Master Information Block (MIB) signaling, System Information Block (SIB) signaling, RRC signaling, Media Access Control (MAC) signaling, and physical layer downlink control signaling. The RRC signaling may include one of the following: UE-specific RRC signaling and Common RRC signaling.

[0071] In some embodiments, the BWP is a BWP used by the first node in a non-connected state. Exemplarily, the non-connected state includes an idle state and / or an inactive state.

[0072] In some embodiments, the scope of application of BWP includes at least one of the following: BWP is applicable to one or more cells; BWP is applicable to one or more transmission and receiving points (TRP); BWP is applicable to one or more beams; BWP is applicable to one or more carriers, where a carrier refers to a continuous frequency domain.

[0073] In some embodiments, when a BWP is applicable to multiple cells, TRPs, carriers, or beams, the BWP configuration information includes at least one of the following: a list of cells to which the BWP is applicable, a list of TRPs to which the BWP is applicable, a list of beams to which the BWP is applicable, a list of carriers to which the BWP is applicable, and an identifier of a region to which the BWP is applicable, where a region includes one or more cells. A carrier is a continuous spectrum.

[0074] It can be understood that compared with the method of configuring BWP based on cells, the scope of application of the BWP provided in the embodiment of the present disclosure may include multiple cells or multiple TRPs or multiple beams or multiple carriers, etc. In this way, when the first node switches between multiple cells or multiple TRPs or multiple beams or multiple carriers, there is no need to switch the BWP. It can be seen that the BWP configured in the embodiment of the present disclosure is more flexible, has a wider scope of application, can save signaling overhead, and reduce terminal power consumption.

[0075] In some embodiments, when a BWP is applicable to a cell, the BWP configuration information includes a BWP configuration list with a cell configuration unit as the granularity. The cell configuration unit includes a cell identifier and the configuration information of the BWP applicable to the cell.

[0076] In some embodiments, when a BWP is applicable to a TRP, the BWP configuration information includes a BWP configuration list with TRP configuration units as the granularity. The TRP configuration unit includes a TRP identifier and the configuration information of the BWP applicable to the TRP.

[0077] In some embodiments, when a BWP is applicable to a beam, the BWP configuration information includes a BWP configuration list with a beam configuration unit as the granularity. The beam configuration unit includes a beam identifier and the configuration information of the BWP applicable to the beam.

[0078] In some embodiments, when a BWP is applicable to a carrier, the BWP configuration information includes a BWP configuration list with a carrier configuration unit as the granularity. The carrier configuration unit includes a carrier identifier and the configuration information of the BWP applicable to the carrier.

[0079] In some embodiments, the BWP includes a first BWP used when the first node resides in the applicable range. Exemplarily, the first BWP may be a BWP used when the first node resides in a cell, a TRP, a beam, or a carrier.

[0080] As an implementation manner, when the applicable scope in which the first node resides belongs to the applicable scope of the first BWP, the first BWP is in a valid state.

[0081] Exemplarily, when the cell in which the first node resides belongs to one or more applicable cells of the first BWP, the first BWP is in a valid state; or, when the TRP in which the first node resides belongs to one or more applicable TRPs of the first BWP, the first BWP is in a valid state; or, when the beam in which the first node resides belongs to one or more applicable beams of the first BWP, the first BWP is in a valid state; or, when the carrier in which the first node resides belongs to one or more applicable carriers of the first BWP, the first BWP is in a valid state.

[0082] As another implementation manner, when the applicable scope where the first node resides belongs to the applicable scope of the first BWP and a preset condition is met, the first BWP is in a valid state.

[0083] Exemplarily, the above-mentioned preset conditions include at least one of the following:

[0084] The measured value of the channel state information is less than or equal to a first threshold;

[0085] The measured value of the channel state information is greater than a second threshold;

[0086] The TRP accessed by the first node is the TRP configured for the second node;

[0087] The index of the beam received by the first node is the index of the beam configured by the second node;

[0088] The first node is in a predefined state; illustratively, the predefined state may include: an idle state, an inactive state, and a connected state;

[0089] The duration of the timer is less than the third threshold, and the duration of the timer is used to represent the duration of continuous use of the first BWP, or the duration of the first node's residence in the cell to which the first BWP is applicable, or the duration of the first node's residence in the TRP to which the first BWP is applicable, or the duration of the first node's residence in the beam to which the first BWP is applicable, or the duration of the first node's residence in the carrier to which the first BWP is applicable.

[0090] Exemplarily, when the first BWP is applicable to multiple cells, the duration of the above-mentioned timer being less than the third threshold may include the following two situations: the duration of the first node's residence in a cell to which the first BWP is applicable is less than the third threshold; or the total duration of the first node's residence in multiple cells to which the first BWP is applicable is less than the third threshold.

[0091] Exemplarily, when the first BWP is applicable to multiple TRPs, the duration of the above-mentioned timer being less than the third threshold may include the following two situations: the duration that the first node resides in a TRP to which the first BWP is applicable is less than the third threshold; or, the total duration that the first node resides in multiple TRPs to which the first BWP is applicable is less than the third threshold.

[0092] Exemplarily, when the first BWP is applicable to multiple beams, the duration of the above-mentioned timer being less than the third threshold may include the following two situations: the duration for which the first node resides in a beam to which the first BWP is applicable is less than the third threshold; or the total duration for which the first node resides in multiple beams to which the first BWP is applicable is less than the third threshold.

[0093] Exemplarily, when the first BWP is applicable to multiple carriers, the duration of the above-mentioned timer being less than the third threshold may include the following two situations: the duration of the first node's residence in a carrier to which the first BWP is applicable is less than the third threshold; or the total duration of the first node's residence in multiple carriers to which the first BWP is applicable is less than the third threshold.

[0094] In some embodiments, when the applicable scope in which the first node resides does not belong to the applicable scope of the first BWP, the first BWP is in an invalid state; or, when the applicable scope in which the first node resides belongs to the applicable scope of the first BWP but does not meet the preset conditions, the first BWP is in an invalid state.

[0095] In some embodiments, the BWP includes a second BWP; the second BWP is a BWP used when the first BWP is in an invalid state, or a BWP used when the first BWP is not configured.

[0096] Exemplarily, the second BWP may be a BWP for fallback. For example, the second BWP is a BWP for fallback used when the first BWP is in an invalid state.

[0097] In some embodiments, the configuration information of the BWP includes: first configuration information and second configuration information; the first configuration information is used to represent the configuration information of the BWP itself, and the second configuration information is used to represent the communication configuration information related to the BWP.

[0098] The first configuration information includes at least one of the following: frequency domain position, subcarrier spacing, and cyclic prefix type; the second configuration information includes at least one of the following: channel information and signal information.

[0099] Exemplarily, the frequency domain position includes one or more continuous frequency domain positions. Multiple continuous frequency domain positions can independently indicate the starting position and the continuous bandwidth, or multiple continuous frequency domain positions can be jointly indicated, for example, the starting position and the continuous bandwidth of multiple continuous frequency domains are indicated by joint coding.

[0100] Exemplarily, the above-mentioned subcarrier spacing may include one or more types. When the BWP includes multiple continuous frequency domain positions, each continuous frequency domain position corresponds to a separate subcarrier spacing configuration and / or cyclic prefix type configuration.

[0101] In some embodiments, one piece of first configuration information corresponds to one or more pieces of second configuration information; and / or, one piece of second configuration information corresponds to one or more pieces of first configuration information.

[0102] It can be understood that a first configuration information corresponding to one or more second configuration information means that a first configuration information set can be associated with one or more second configuration information sets; a second configuration information corresponding to one or more first configuration information means that a second configuration information set can be associated with one or more first configuration information sets.

[0103] Exemplarily, the identifier of the first configuration information can be expressed as BWP-In-Id; the identifier of the second configuration information can be expressed as BWP-Out-Id; then one BWP-In-Id can correspond to one or more BWP-Out-Ids; and one BWP-Out-Id can correspond to one or more BWP-In-Ids.

[0104] It can be understood that if the configuration of the BWP itself and the communication configuration information related to the BWP (for example, channel information, signal information, measurement information such as PDCCH\PDSCH\PUSCH\PUCCH\PRACH) are associated with a BWP-Id, that is, the information corresponding to a BWP or a BWP-Id is fixed. Since the number of configured BWP-Ids is limited, the number of BWPs that can be configured with different information is also limited.

[0105] Since BWP actually reflects frequency domain location information, and frequency domain location information has no strong correlation with the channel information, signal information, or measurement information corresponding to the frequency domain, associating frequency domain location information with the channel information, signal information, or measurement information corresponding to the frequency domain limits configuration flexibility. For the same frequency domain location, as time changes, its corresponding air interface channel changes, the corresponding interference situation also changes, the number of users residing at the frequency domain location also changes, and the type of service transmitted corresponding to the frequency domain location also changes. Therefore, associating a frequency domain location (a BWP or a BWP-ID) with channel information, signal information, or measurement information limits configuration flexibility and cannot match changes in the channel, service, user, or interference in the frequency domain, thereby reducing transmission efficiency and affecting the performance of the entire system.

[0106] Therefore, to address the above technical issues, the embodiments of the present disclosure separate the first configuration information representing the configuration information of the BWP itself from the second configuration information representing the communication configuration information related to the BWP. In addition, one first configuration information can correspond to one or more second configuration information, and one second configuration information can correspond to one or more first configuration information. In this way, the flexibility of the configuration can be improved, so that the configuration information of the BWP itself can match the changes in the channel, service, user, interference, etc. in the frequency domain, thereby improving transmission efficiency and system performance. When one first configuration information can correspond to multiple second configuration information, during use, physical layer signaling can dynamically indicate which second configuration information the first configuration information corresponds to.

[0107] In some embodiments, the type of the first configuration information includes downlink first configuration information and / or uplink first configuration information.

[0108] Exemplarily, the identifier of the first downlink configuration information may be expressed as DL-BWP-In-Id, and the identifier of the first uplink configuration information may be expressed as UL-BWP-In-Id.

[0109] In some embodiments, when the type of the second configuration information is downlink second configuration information, the downlink second configuration information includes at least one of the following: PDCCH information, PDSCH information, measurement information, and downlink synchronization signal information.

[0110] Exemplarily, the identifier of the second downlink configuration information may be expressed as DL-BWP-Out-Id.

[0111] In some embodiments, when the type of the second configuration information is uplink second configuration information, the uplink second configuration information includes at least one of the following: PRACH information, PUSCH information, SRS (Sounding Reference Signal) information, PUCCH information, and request signal information.

[0112] In some embodiments, the uplink second configuration information may further include at least one of the following: positioning information, perception information, and scheduling request (SR) information.

[0113] Exemplarily, the identifier of the second uplink configuration information may be expressed as UL-BWP-Out-Id.

[0114] For example, the UL-BWP-In-Id and UL-BWP-Out-Id may be associated with the uplink BWP identifier (UL-BWP-Id); the DL-BWP-In-Id and DL-BWP-Out-Id may be associated with the downlink BWP identifier (DL-BWP-Id). For example, the BWP configuration information may be expressed in the following form:

[0115] Alternatively, the BWP configuration information can also be expressed in the following form:

[0116] It is understood that the embodiments of the present disclosure, through separate configurations, can define the maximum capabilities supported by a terminal for both the BWP's own configuration information and the BWP-related communication configuration information, thereby increasing configuration flexibility. For example, although a terminal has a maximum limit of n1 for the number of BWP-In-Ids and a maximum limit of n2 for the number of BWP-Out-Ids, the actual number of BWP configurations that a terminal can ultimately accept is n1*n2. This multi-dimensional division of configuration and corresponding capability definition breaks the configuration constraints imposed by a single capability limitation and enhances BWP configuration flexibility.

[0117] In some embodiments, the above method further includes: adding maximum quantity information of the first configuration information (BWP-In-Id) and / or maximum quantity information of the second configuration information (BWP-Out-Id) to the capability information of the first node.

[0118] S202: The first node uses the BWP based on the configuration information of the BWP.

[0119] In some embodiments, when the type of the BWP is a downlink BWP, the first node may use the downlink BWP to perform at least one of the following: PDCCH detection, paging monitoring, downlink measurement, and downlink synchronization.

[0120] In some embodiments, when the type of BWP is an uplink BWP, the first node may use the uplink BWP to perform at least one of the following: PRACH transmission, scheduling request (SR) transmission, confirmation signal (ACK) transmission, rejection signal (Negative Acknowledgement, NACK) transmission, CSI transmission, SRS transmission, and request signal transmission.

[0121] The request signal includes at least one of the following: SIB, synchronization signal, cell activation signal, downlink scheduling signal, and uplink scheduling signal.

[0122] Exemplarily, when the first node is in a non-connected state, the first node resides on the downlink BWP and monitors the PDCCH in the search space corresponding to the PDCCH according to the PDCCH configuration information (for example, the PDCCH search space period, the aggregation level, etc.); accordingly, the second node transmits the PDCCH through the search space, wherein the information that the PDCCH can transmit includes at least one of the following: the location of the PDSCH carrying the paging message, the system message change indication, the use of the fallback BWP indication, the access network indication, the sending of the uplink measurement signal indication, the sending of the uplink positioning signal indication, the sending of the uplink perception signal indication, and the downlink perception signal indication.

[0123] For example, when the first node monitors the PDCCH and obtains the access network indication from the PDCCH, it selects PRACH access on the uplink BWP according to PRACH configuration information (eg, PRACH time-frequency location information, PRACH sequence set, etc.).

[0124] For example, when the first node monitors the PDCCH and obtains an indication of sending an uplink measurement signal, an indication of sending an uplink positioning signal, or an indication of sending an uplink perception signal from the PDCCH, the first node sends an SRS signal, an uplink positioning signal, or an uplink perception signal on the uplink BWP according to the SRS information, positioning information, or perception information.

[0125] For example, when the first node has uplink data transmission, on the uplink BWP, the first node sends PRACH or SR according to PRACH information or SR information (eg, SR time-frequency location information, etc.) The first node performs measurement according to downlink synchronization information.

[0126] Exemplarily, when the type of the BWP is a downlink BWP, the first node performs measurement on the downlink BWP according to the downlink synchronization information.

[0127] It is understandable that since there is no solution for configuring a terminal-specific BWP in a non-connected state, the configuration flexibility is limited, which affects the network performance. In this regard, the embodiment of the present disclosure configures a BWP that can reside in a non-connected state, which solves this problem, improves the flexibility of BWP configuration, and improves network performance.

[0128] In some embodiments, when the configuration information of the BWP includes first configuration information and second configuration information, the above method further includes: the second node sends a second signaling to the first node; and correspondingly, the first node receives the second signaling.

[0129] The second signaling is used to indicate a correspondence between at least one first configuration information and at least one second configuration information.

[0130] Exemplarily, the second signaling may be carried in DCI.

[0131] In some embodiments, the DCI includes at least one BWP-In-Id configuration (Bandwidth part corrset indicator), at least one BWP-Out-Id configuration (Bandwidth part associated configuration indicator), and an indication of the correspondence between at least one BWP-In-Id and at least one BWP-Out-Id. This allows for dynamic association between BWP-In-Id and BWP-Out-Id configurations, better matching channel and service changes, and thus improving spectrum efficiency and system performance.

[0132] Exemplarily, BWP-In-Id configuration and BWP-Out-Id configuration are added to the uplink DCI Format (DCI format); and / or, BWP-In-Id configuration and BWP-Out-Id configuration are added to the downlink DCI Format to implement dynamic configuration.

[0133] In some embodiments, to further enhance BWP configuration flexibility, the DCI dynamically indicates both the BWP-In-Id and BWP-Out-Id configurations and at least one of the following: the BWP's starting frequency domain location, bandwidth, or subcarrier spacing. This eliminates the need to configure BWP frequency domain location and subcarrier spacing via RRC. DCI can flexibly indicate both the BWP's frequency domain location and corresponding BWP configuration.

[0134] Exemplarily, the second signaling is at least one of the following: MIB signaling, SIB signaling, RRC signaling, MAC signaling, and physical layer downlink control signaling. The RRC signaling may include one of the following: UE-specific RRC signaling and Common RRC signaling.

[0135] In some embodiments, the method further includes: the second node sending a third signaling to the first node; and correspondingly, the first node receiving the third signaling. The third signaling is used to indicate activation of multiple groups of BWPs or multiple BWPs.

[0136] Exemplarily, the third signaling mentioned above may be carried in DCI.

[0137] It is understandable that when the first node has the ability to support activation of multiple BWPs, BWP group activation signaling can also be added in the DCI to indicate the activation of one or more groups of BWPs, where a group of BWPs can be one or more groups of BWPs configured by RRC. A group of BWPs can include multiple BWPs.

[0138] For example, assuming that RRC configures 16 groups of BWPs, one group of BWPs in the 16 groups can be activated by indicating through 4 bits in DCI; or, assuming that RRC configures 15 BWPs, any one or two of the 15 BWPs can be activated by indicating through 7 bits in DCI; or, assuming that RRC configures 4 BWPs, any one or more of the 4 BWPs can be activated by indicating through 4 bits in DCI (each bit corresponds to a BWP). It can be understood that the BWP indicated for activation in the DCI signaling can be a BWP in one cell or in multiple cells, a BWP on one carrier or on multiple carriers.

[0139] Exemplarily, the third signaling is at least one of the following: MIB signaling, SIB signaling, RRC signaling, MAC signaling, and physical layer downlink control signaling. The RRC signaling may include one of the following: UE-specific RRC signaling and Common RRC signaling.

[0140] In some embodiments, as shown in FIG3 , before the above step S201 , the above method further includes the following steps S301 - S302 .

[0141] S301: The first node determines an initial BWP.

[0142] The initial BWP bandwidth is a minimum bandwidth determined based on the entire bandwidth or a portion of the bandwidth of the physical broadcast channel (PBCH) and / or the entire bandwidth or a portion of the bandwidth of the downlink synchronization signal. For example, among the configured bandwidths, the minimum integer bandwidth greater than or equal to the PBCH bandwidth and / or the downlink synchronization signal bandwidth is selected.

[0143] For example, assuming that the configured bandwidths include: 3M, 5M, 10M, 15M, 20M, 40M, 50M, 60M, 100M, 200M; assuming that the PBCH bandwidth and / or downlink synchronization signal bandwidth is 2.88M (15KHz subcarrier spacing, the number of physical resource blocks is 16), the initial BWP bandwidth is 3M; assuming that at low frequency (FR1), the maximum bandwidth of the PBCH bandwidth and / or downlink synchronization signal is 4.32M (30KHz subcarrier spacing, the number of physical resource blocks is 16). The initial BWP bandwidth is 5M if the subcarrier spacing is 12 and the number of physical resource blocks is 12). If the PBCH bandwidth and / or the maximum bandwidth of the downlink synchronization signal is 17.28M (120KHz subcarrier spacing and 12 physical resource blocks) at the intermediate frequency (FR2), the initial BWP bandwidth is 20M. If the PBCH bandwidth and / or the maximum bandwidth of the downlink synchronization signal is 69.12M (480KHz subcarrier spacing and 12 physical resource blocks) at the intermediate frequency (FR3), the initial BWP bandwidth is 100M.

[0144] In addition, the PBCH and / or downlink synchronization signal can be divided into multiple parts in the frequency domain. The parts can be transmitted in a repetitive manner, or can be mapped to each part in sequence using a coding rate matching method or different sequences. The initial BWP bandwidth is determined based on the bandwidth of at least one of the multiple parts of the PBCH and / or downlink synchronization signal.

[0145] Exemplarily, the PBCH and / or downlink synchronization signal is divided into two parts in the frequency domain, and the frequency domain bandwidth of each part is the same. The parts can be transmitted in a repeated manner, or a coding rate matching method can be used (first mapping in the first part frequency domain, then mapping in the second part frequency domain) or different sequences can be used. The initial BWP bandwidth is determined according to the frequency domain bandwidth of a part in the PBCH and / or downlink synchronization signal, and the determination method can adopt the above method.

[0146] Alternatively, the PBCH and / or downlink synchronization signal is divided into three parts in the frequency domain, and the frequency domain bandwidth of each part is the same. The parts can be transmitted in a repeated manner, or a coding rate matching method can be used (first mapping in the first part frequency domain, then mapping in the second part frequency domain, and finally mapping in the third part frequency domain) or different sequences can be used. The initial BWP bandwidth is determined according to the frequency domain bandwidth of a part in the PBCH and / or downlink synchronization signal, and the determination method can adopt the above method.

[0147] The terminal may receive only one of the multiple parts to access the network, or may receive two or more parts to access the network.

[0148] It is understandable that, with respect to the method of configuring the initial BWP bandwidth, the embodiment of the present disclosure can determine the minimum bandwidth of the BWP based on the PBCH bandwidth and / or the downlink synchronization signal bandwidth, thereby saving resources and reducing terminal energy consumption.

[0149] S302: The first node uses the initial BWP.

[0150] In some embodiments, the above method further includes configuring a PDCCH search space for scheduling SIBs on the initial BWP.

[0151] In some embodiments, as shown in FIG4 , the above method further includes the following steps S401 - S402 .

[0152] S401. The second node sends a fourth signaling to the first node; accordingly, the first node receives the fourth signaling.

[0153] The fourth signaling includes configuration information of the third BWP; the third BWP is the BWP used by the first node in the connected state.

[0154] In some embodiments, the scope of application of the third BWP includes at least one of the following: the third BWP is applicable to one or more cells; the third BWP is applicable to one or more TRPs; the third BWP is applicable to one or more beams; the third BWP is applicable to one or more carriers.

[0155] In some embodiments, the configuration information of the third BWP includes at least one of the following: a list of cells to which the third BWP is applicable, a list of TRPs to which the third BWP is applicable, a list of beams to which the third BWP is applicable, a list of carriers to which the third BWP is applicable, and an identifier of an area to which the third BWP is applicable, where the area includes one or more cells.

[0156] In some embodiments, the third BWP may include an uplink third BWP and a downlink third BWP.

[0157] Exemplarily, the fourth signaling may include at least one of the following: MIB signaling, SIB signaling, RRC signaling, MAC signaling, and physical layer downlink control signaling. The RRC signaling may include one of the following: UE-specific RRC signaling and Common RRC signaling.

[0158] S402: The first node uses the third BWP based on configuration information of the third BWP.

[0159] It can be understood that compared with the BWP of the terminal in the connected state which is based on the cell configuration, the applicable scope of the BWP of the terminal in the connected state provided in the embodiment of the present disclosure may include multiple cells or multiple TRPs or multiple beams or multiple carriers, etc. In this way, when the first node switches between multiple cells or multiple TRPs or multiple beams or multiple carriers, there is no need to switch the BWP. It can be seen that the BWP configured in the embodiment of the present disclosure is more flexible, has a wider scope of application, can save signaling overhead, and reduce terminal power consumption.

[0160] For ease of understanding, the information transmission method provided by the embodiment of the present disclosure is described below in the form of examples.

[0244] As an implementation manner, when the applicable scope where the terminal resides belongs to the applicable scope of the first BWP, the first BWP is in a valid state.

[0245] Exemplarily, when the cell where the terminal resides belongs to one or more applicable cells of the first BWP, the first BWP is in a valid state; or, when the TRP where the terminal resides belongs to one or more applicable TRPs of the first BWP, the first BWP is in a valid state; or, when the beam where the terminal resides belongs to one or more applicable beams of the first BWP, the first BWP is in a valid state; or, when the carrier where the terminal resides belongs to one or more applicable carriers of the first BWP, the first BWP is in a valid state.

[0251] The request signal includes at least one of the following: SIB, synchronization signal, cell activation signal, downlink scheduling signal, and uplink scheduling signal.

[0252] Example 2: Provide a BWP for fallback in a non-connected state.

[0253] Exemplarily, the information transmission method provided by the embodiment of the present disclosure can be implemented as the following steps b1-b2.

[0254] Step b1: The base station sends a first signaling to the terminal; correspondingly, the terminal receives the first signaling.

[0255] The first signaling includes configuration information for a second BWP. The second BWP is a fallback BWP used by the terminal in a disconnected state. For example, the second BWP is a fallback BWP used when the first BWP is in an invalid state; or, alternatively, the second BWP is a fallback BWP used when the first BWP is not configured.

[0256] In some embodiments, the scope of application of the second BWP includes at least one of the following: the second BWP is applicable to one or more cells; the second BWP is applicable to one or more TRPs; the second BWP is applicable to one or more beams; the second BWP is applicable to one or more carriers.

[0260] Exemplarily, the contents included in the cell configuration unit can be found in the description of step a1 above, which will not be repeated here.

The TRP configuration unit includes a TRP identifier and the configuration information of the BWP applicable to the TRP.

[0262] Exemplarily, the contents included in the TRP configuration unit can be found in the description of step a1 above, which will not be repeated here.

[0266] Step b2: The terminal uses the second BWP based on the configuration information of the second BWP.

[0267] In some embodiments, when the applicable scope where the terminal resides does not belong to the applicable scope of the first BWP, the terminal uses the second BWP; or, when the terminal is not configured with the above-mentioned first BWP, the terminal uses the second BWP.

[0268] In some embodiments, when the type of the second BWP is a downlink second BWP, the terminal may use the downlink second BWP to perform at least one of the following: PDCCH detection, paging monitoring, downlink measurement, and downlink synchronization.

[0269] In some embodiments, when the type of the second BWP is an uplink second BWP, the terminal may use the uplink second BWP to perform at least one of the following: PRACH transmission, SR transmission, ACK transmission, NACK transmission, CSI transmission, SRS transmission, and request signal transmission.

[0270] The above request signal includes at least one of the following: SIB request, synchronization signal request, cell activation signal request, downlink scheduling request signal, and uplink scheduling request signal.

[0271] To more flexibly define a terminal's BWP capability, you can define the terminal's support for dynamic BWP switching, where the BWP bandwidth is less than or equal to the receive bandwidth. Within this receive bandwidth, the base station can dynamically select any BWP to activate, as well as the number of BWPs the terminal supports being simultaneously active within that receive bandwidth. Furthermore, you can define the terminal's support for aggregating several discontinuous spectrum bands into a single receive bandwidth. You can also define the terminal's maximum BWP bandwidth capability, where the maximum BWP bandwidth is less than or equal to the receive bandwidth.

[0272] In some embodiments, the terminal reports at least one of the following capabilities to the base station: receiving bandwidth capability, number of BWPs supported for simultaneous activation, capability to support aggregation of discontinuous spectrum into one receiving bandwidth, and BWP maximum bandwidth capability.

[0273] Correspondingly, after receiving the capability reported by the terminal, the base station sends BWP configuration information to the terminal according to the terminal capability.
