Technical Field

[0001] This application relates to the field of wireless communication technology, and more specifically, to a method and apparatus in a wireless communication system. Background Technology

[0002] Given the successive generations of wireless communication development, these technologies have primarily been developed for human-oriented services such as voice calls, multimedia services, and data services. With the commercialization of 5th-generation (5G) communication systems, the number of connected devices is expected to grow exponentially. These will increasingly connect to communication networks. Examples of the Internet of Things (IoT) can include vehicles, robots, drones, home appliances, displays, smart sensors connected to various infrastructures, construction machinery, and factory equipment. Mobile devices are expected to evolve in various forms, such as augmented reality glasses, virtual reality headsets, and holographic devices. Efforts are underway to develop improved 6G communication systems to provide a wide range of services by connecting hundreds of billions of devices and things in the sixth-generation (6G) era.

[0003] The 6G communication system, expected to be commercially available around 2030, will significantly improve upon existing 5G communication systems in all aspects. Its peak speed will reach at least 50 Gbit / s, user experience speed will reach at least 300 Mbit / s, air interface latency will be less than 1 ms, and air interface reliability will reach 10^(-5). In addition to these basic communication indicators, the 6G communication system will also possess sensing capabilities, AI-related capabilities, and better security, interoperability, and sustainability.

[0004] To achieve the aforementioned performance indicators for 6G communication systems, more advanced air interface and network technologies are needed. Currently, the evolution of extreme multiple input multiple output (MIMO) is being considered, including the use of very large-scale antenna arrays, the development and evolution of distributed antenna systems, and the design of MIMO air interface algorithms assisted by artificial intelligence (AI). This technology can achieve higher spectral efficiency, greater coverage, and more precise positioning and sensing capabilities. Furthermore, technologies that contribute to improving high-frequency coverage, including metamaterial-based lenses and antennas, novel antenna architectures, and reconfigurable intelligence surfaces (RIS), also require further evolution and development.

[0005] To meet the new functionalities added to 6G communication systems, it is necessary to develop new technologies in areas such as network energy saving, air interface security, and network security, while also studying the feasibility of converged technologies such as integrated communication and sensing.

[0006] In addition, to improve spectrum efficiency and overall network performance, the following technologies have been developed for 6G communication systems: full-duplex technology to enable uplink and downlink transmissions to use the same frequency resources simultaneously; network technologies that utilize satellites, high-altitude platform stations (HAPS), etc., in a comprehensive manner; improved network architecture to support mobile base stations, etc., and to enable network operation optimization and automation; dynamic spectrum sharing technology based on spectrum usage prediction and conflict avoidance; the use of artificial intelligence (AI) in wireless communication to improve overall network operation by utilizing AI from the design phase of 6G development and internalizing end-to-end AI support functions; and next-generation distributed computing technologies that overcome the computing power limitations of user equipment (UE) by leveraging ultra-high-performance communication and computing resources (such as mobile edge computing (MEC), cloud, etc.) achievable on the network. Furthermore, efforts are continuing to enhance connectivity between devices, optimize networks, promote the software-defined networking of network entities, and increase the openness of wireless communications by designing new protocols to be used in 6G communication systems, developing mechanisms for achieving hardware-based secure environments and secure data use, and developing technologies for maintaining privacy.

[0007] The research and development of 6G communication systems, encompassing hyper-connectivity for both person-to-machine (P2M) and machine-to-machine (M2M) interactions, is expected to deliver the next wave of hyper-connected experiences. Specifically, services such as truly immersive extended reality (XR), high-fidelity mobile holograms, and digital replicas are anticipated to be provided through 6G communication systems. Furthermore, services such as remote surgery for enhanced security and reliability, industrial automation, and emergency response will be available via 6G communication systems, enabling the technology to be applied across a wide range of sectors including industry, healthcare, automotive, and home appliances.

Figure 2 The embodiment of gNB 102 shown is for illustrative purposes only, and Figure 1 gNBs 101 and 103 can have the same or similar configurations. However, gNBs come in a variety of configurations, and Figure 2 This disclosure is not intended to limit the scope to any particular implementation of gNB.

[0074] like Figure 2 As shown, gNB 102 includes multiple antennas 200a 200n, multiple radio frequency (RF) transceivers 201a 201n, transmit (TX) processing circuitry 203, and receive (RX) processing circuitry 204. gNB 102 also includes a controller / processor 205, a memory 206, and a backhaul or network interface 207.

[0075] RF transceivers 201a and 201n receive incoming RF signals, such as signals transmitted by the UE in network 100, from antennas 200a and 200n. RF transceivers 201a and 201n down-convert the incoming RF signals to generate intermediate frequency (IF) or baseband signals. The IF or baseband signal is sent to RX processing circuitry 204, which generates a processed baseband signal by filtering, decoding, and / or digitizing the baseband or IF signal. RX processing circuitry 204 sends the processed baseband signal to controller / processor 205 for further processing.

[0076] TX processing circuit 203 receives analog or digital data (such as voice data, web data, email, or interactive video game data) from controller / processor 205. TX processing circuit 203 encodes, multiplexes, and / or digitizes the outgoing baseband data to generate a processed baseband or IF signal. RF transceivers 201a and 201n receive the processed baseband or IF signal from TX processing circuit 203 and up-convert the baseband or IF signal into an RF signal transmitted via antennas 201a and 201n.

[0077] The controller / processor 205 may include one or more processors or other processing devices that control the overall operation of the gNB 102. For example, the controller / processor 205 may control the reception of forward channel signals and the transmission of reverse channel signals by the RF transceivers 201a 201n, the RX processing circuit 204, and the TX processing circuit 203, according to known principles. The controller / processor 205 may also support additional functions, such as more advanced wireless communication capabilities.

[0078] For example, the controller / processor 205 can support beamforming or directional routing operations, where outgoing signals from multiple antennas 200a 200n are weighted differently to effectively redirect the outgoing signals in the desired direction. Any of a variety of other functions can be supported in the gNB 102 via the controller / processor 205.

[0079] The controller / processor 205 is also capable of executing programs and other processes located in the memory 206, such as the operating system (OS). The controller / processor 205 can move data into or out of the memory 206 as needed by the executing process.

[0080] The controller / processor 205 is also connected to a backhaul or network interface 207. The backhaul or network interface 207 allows the gNB 102 to communicate with other devices or systems via a backhaul connection or over a network. Interface 207 can support communication via any suitable wired or wireless connection(s). For example, when the gNB 102 is implemented as part of a cellular communication system (such as a cellular communication system supporting 5G, LTE, or LTE A), interface 207 can allow the gNB 102 to communicate with other gNBs via a wired or wireless backhaul connection. When the gNB 102 is implemented as an access point, interface 207 can allow the gNB 102 to communicate via a wired or wireless local area network or via a wired or wireless connection to a larger network (such as the Internet). Interface 207 includes any suitable structure that supports communication via wired or wireless connections such as Ethernet or RF transceivers.

[0081] Memory 206 is connected to controller / processor 205. A portion of memory 206 may include random access memory (RAM), and another portion of memory 206 may include flash memory or other read-only memory (ROM).

[0082] although Figure 2 An example of gNB 102 is shown, but it is possible to see more. Figure 2 Various changes can be made. For example, gNB 102 can include any number of Figure 2 Each component is shown in the diagram. As a specific example, an access point may include multiple interfaces 207, and the controller / processor 205 may support routing functionality to route data between different network addresses. As another specific example, although shown as a single instance of TX processing circuitry 203 and a single instance of RX processing circuitry 204, gNB102 may include multiple instances of each (such as one per RF transceiver). For example, Figure 2 The various components can be combined, further subdivided, or omitted, and additional components can be added as needed.

[0083] Figure 3 An example user equipment according to an embodiment of the present disclosure is shown. Figure 3 The embodiment of UE 116 shown is for illustrative purposes only, and Figure 1 UEs 111, 115, 117, and 119 can have the same or similar configurations. However, UEs appear in multiple configurations, and Figure 3 This disclosure is not intended to limit the scope to any particular implementation of the UE.

[0084] like Figure 3 As shown, UE 116 includes an antenna 301, a radio frequency (RF) transceiver 302, a TX processing circuit 303, a microphone 304, and a receive (RX) processing circuit 305. UE 116 also includes a speaker 306, a controller or processor 307, an input / output (I / O) interface (IF) 308, an input device 309, a touchscreen display 310, and memory 311. Memory 311 includes an OS 312 and one or more applications 313.

[0085] RF transceiver 302 receives incoming RF signals transmitted by gNB of network 100 from antenna 301. RF transceiver 302 down-converts the incoming RF signals to generate IF or baseband signals. The IF or baseband signals are sent to RX processing circuitry 305, which generates processed baseband signals by filtering, decoding, and / or digitizing the baseband or IF signals. RX processing circuitry 305 sends the processed baseband signals to speaker 306 (e.g., for voice data) or processor 307 for further processing (e.g., for web browsing data).

[0086] TX processing circuit 303 receives analog or digital voice data from microphone 304 or other outgoing baseband data (such as web data, email, or interactive video game data) from processor 307. TX processing circuit 303 encodes, multiplexes, and / or digitizes the outgoing baseband data to generate a processed baseband or IF signal. RF transceiver 302 receives the processed baseband or IF signal from TX processing circuit 303 and up-converts the baseband or IF signal into an RF signal transmitted via antenna 301.

[0087] Processor 307 may include one or more processors or other processing devices and executes OS 312 stored in memory 311 to control the overall operation of UE 116. For example, processor 307 may control the reception of forward channel signals and the transmission of reverse channel signals by RF transceiver 302, RX processing circuitry 305, and TX processing circuitry 303 according to known principles. In some embodiments, processor 307 includes at least one microprocessor or microcontroller.

[0088] Processor 307 is also capable of executing other processes and programs located in memory 311, such as processes for CSI reporting on the uplink channel. Processor 307 can move data into or out of memory 311 as needed for executing processes. In some embodiments, processor 307 is configured to execute application 313 based on OS 312 or in response to signals received from gNB or operator. Processor 307 is also coupled to I / O interface 308, which provides UE 116 with the ability to connect to other devices such as laptops and laptops. I / O interface 308 is the communication path between these accessories and processor 307.

[0089] The processor 307 is also connected to the touchscreen display 310. The user of the UE 116 can use the touchscreen display 310 to input data into the UE 116. The touchscreen display 310 can be a liquid crystal display, a light-emitting diode display, or other display capable of rendering text and / or at least limited graphics such as those from a website.

[0090] Memory 311 is connected to processor 307. A portion of memory 311 may include RAM, and another portion of memory 311 may include flash memory or other ROM.

[0091] although Figure 3 An example of UE 116 is shown, but it is possible to modify it. Figure 3 Make various changes. For example, Figure 3 The various components can be combined, further subdivided, or omitted, and additional components can be added as needed. As a specific example, processor 307 can be divided into multiple processors, such as one or more central processing units (CPUs) and one or more graphics processing units (GPUs). Moreover, although... Figure 3 The UE 116 is shown configured as a mobile phone or smartphone, but the UE can be configured to operate as other types of mobile or fixed devices.

[0092] The time unit (also called a time cell) in this application can be: an OFDM symbol, an OFDM symbol group (composed of multiple OFDM symbols), a time slot, a time slot group (composed of multiple time slots), a subframe, a subframe group (composed of multiple subframes), a system frame, or a system frame group (composed of multiple system frames); it can also be an absolute time unit, such as 1 millisecond, 1 second, etc.; the time unit can also be a combination of multiple granularities, such as N1 time slots plus N2 OFDM symbols. It can also be the time length of an OOK chip.

[0093] The frequency domain unit (also called frequency unit) in this application can be: a subcarrier, a subcarrier group (composed of multiple subcarriers), a resource block (RB), also called a physical resource block (PRB), a resource block group (composed of multiple RBs), a bandwidth part (BWP), a bandwidth part group (composed of multiple BWPs), a bandwidth / carrier, a bandwidth group / carrier group; it can also be an absolute frequency domain unit, such as 1 Hz, 1 kHz, etc.; the frequency domain unit can also be a combination of multiple granularities, such as M1 PRBs plus M2 subcarriers.

[0094] Exemplary embodiments of this disclosure are further described below with reference to the accompanying drawings.

[0095] The text and accompanying drawings are provided by way of example only to aid the reader in understanding this disclosure. They are not intended and should not be construed as limiting the scope of this disclosure in any way. Although certain embodiments and examples have been provided, it will be apparent to those skilled in the art, based on the content disclosed herein, that changes may be made to the illustrated embodiments and examples without departing from the scope of this disclosure.

[0096] The transmission links of a wireless communication system mainly include: the downlink communication link from gNB to user equipment (UE), the uplink communication link from UE to gNB, and the sidelink communication link from UE to UE.

[0097] In wireless communication systems, such as current ones, the concept of BWP (Bandwidth Switching) is introduced to reduce terminal power consumption and achieve more flexible resource scheduling. This allows each user to dynamically switch bandwidth based on service needs, using high bandwidth to handle large volumes of traffic during peak hours and switching to low bandwidth to reduce power consumption during off-peak hours. However, considering that signals and / or channels are configured based on BWP, the relevant configuration information needs to be reconfigured when BWP switching occurs, resulting in significant BWP switching latency.

[0098] To reduce the latency of signal and / or channel bandwidth switching, wireless communication systems can use a frequency domain resource allocation method to support faster switching of resource allocation information. Therefore, the method for determining the relevant parameters of the frequency domain resources needs to be improved.

[0099] Specifically, this invention will introduce a method and apparatus for configuring or determining signal and / or channel resource parameters. In one embodiment of this invention, the method will be described for determining cell-specific signal and / or channel resources and UE-specific signal and / or channel resources, determining random access resources, and determining a first carrier, wherein the first carrier is a carrier that only supports UEs associated with one carrier.

[0100] Figure 4 A flowchart of a method performed by a UE according to an embodiment of the present disclosure is shown.

[0101] refer to Figure 4 In step S401, the UE may receive multiple sets of cell-specific first configuration information and / or multiple sets of UE-specific second configuration information. Each set of cell-specific first configuration information and / or each set of UE-specific second configuration information includes a control resource set for indicating frequency domain resources for signal and / or channel transmission, and the frequency resource locations corresponding to the multiple control resource sets included in the multiple sets of cell-specific first configuration information and / or multiple sets of UE-specific second configuration information are different.

[0102] In step S402, the UE can determine a set of cell-specific first configuration information from multiple sets of cell-specific first configuration information and / or determine a set of UE-specific second configuration information from multiple sets of UE-specific second configuration information.

[0103] In step S403, the UE may determine resources on one or more frequency bands or carriers for signal and / or channel transmission based on a set of cell-specific first configuration information and / or a set of UE-specific second configuration information.

[0104] In one embodiment, the UE can obtain multiple sets of cell-specific first configuration information through SIB messages. Based on the indication of downlink control information (DCI) or media access control (MAC) control element (CE), the UE determines a set of cell-specific first configuration information. If no DCI or MAC CE indication is received, the UE determines a set of cell-specific first configuration information as the default first configuration information. The default first configuration information can be the first set or the first configuration information with index 0. For example, Random Access Message 1 can determine the frequency domain location of random access resources based on the default first configuration information. The first configuration information is used to determine the resources of control signals and / or channels and / or data signals and / or channels on one or more associated carriers or frequency bands. For example, the first configuration information can be used to determine the frequency domain resource location of cell-specific random access signals and / or channels, and / or control signals and / or channels, and / or data signals and / or channels on one or more carriers associated with the same cell. Optionally, the DCI can be the RA-RNTI scrambled DCI in Random Access Message 2 (Msg2), and the MAC CE can be the MAC CE carried in Random Access Message 2 (Msg2). Configuring multiple sets of cell-specific configuration information can enable flexible configuration of frequency domain resources for Msg3 message transmission, reducing random access latency. For example, configuring multiple sets of cell-specific configuration information is particularly suitable for situations where the transmission period of the Synchronization Signal Block (SSB) has increased due to reduced equipment power consumption. When the transmission period of the SSB increases, the random access latency will increase accordingly. The base station can indicate one of the multiple sets of cell-specific configuration information based on different SSB transmission periods to reduce the random access latency of the UE.

[0105] In one implementation, the first configuration information may include configuration information for uplink signals and / or channels and configuration information for downlink signals and / or channels, wherein the configuration information for uplink signals and / or channels and the configuration information for downlink signals and / or channels include control signals and / or channels and data signals and / or channels. The logical relationship of a set of parameters included in the first configuration information is as follows: Figure 5 As shown, a set of the first configuration information may include at least one of the following:

[0106] A list of candidate aggregated frequency bands or carriers. The list contains values ​​of candidate Absolute Radio Frequency Channel Numbers (ARFCNs) associated with one or more frequency bands or carriers. Optionally, each frequency band or carrier is associated with a specific index value to determine the associated index of one or more frequency bands or carriers. Optionally, the list can be determined based on one or more frequency bands or carriers reported by the UE based on UE capabilities. Optionally, the one or more frequency bands or carriers can be one or more carriers associated with a single cell.

[0107] • First carrier indication. The UE can determine the first carrier as a frequency band or carrier associated with the index value within the list of candidate aggregation frequency bands or carriers by using an index value of the first carrier indication. Based on the UE's capabilities, if the UE does not support associating multiple carriers, the UE only performs the transmission of control signals and / or channels, and data signals and / or channels within the frequency domain of the first carrier;

[0108] • The offset from the PRB0 corresponding to the carrier of the detected SSB to the start position of the frequency domain resource, or the offset from the center frequency position PointA corresponding to the carrier of the detected SSB to the start position of the frequency domain resource. Optionally, the offset represents the offset between the PRB0 or ​​PointA and the start point of the frequency domain resource mapping of the multi-carrier signal and / or channel. The offset can be determined by the number of resource blocks (RBs) or the number of RB groups, and / or the number of frequency bands or carriers within the set of aggregated frequency bands or carriers or the list of candidate aggregated frequency bands or carriers. The UE determines the start point of the frequency domain resource mapping of the multi-carrier signal and / or channel based on the offset and the PRB0 or ​​PointA corresponding to the carrier of the detected SSB. The offset can be positive or negative. If the offset is positive, it indicates that the frequency domain resource start point is higher than the frequency point of the PRB0 or ​​PointA, such as... Figure 6 As shown in (a), if the offset is negative, it indicates that the starting point of the frequency domain resource is lower than the frequency point of PRB0 or ​​Point A, such as... Figure 6 As shown in (b) and (c) in the figure.

[0109] • Bandwidth of the aggregated frequency band or carrier. The bandwidth is indicated by the number of RBs or the number of RB groups, which indicates the number of consecutive RBs or I RB groups on the set of aggregated frequency bands or carriers. Optionally, the number of consecutive RBs or I RB groups does not include the guard interval between frequency bands, and / or does not include the frequency domain spacing between PRB0 and Point A on each aggregated frequency band or carrier within the set of aggregated frequency bands or carriers;

[0110] In another implementation, the frequency domain resource start point and bandwidth of the aggregated band or carrier can be determined by a configured Resource Indication Value (RIV), which is a value calculated based on the offset from the PRB0 corresponding to the carrier detecting the SSB to the frequency domain resource start position and the number of RBs or I RB groups. This operation saves the number of bits used to indicate the frequency domain resource start point and bandwidth.

[0111] • The offset of PRB0 from Point A on each aggregated frequency band or carrier within the set of aggregated frequency bands or carriers, the value of which can be an integer greater than or equal to 0. Optionally, the offset is 0. This operation can indicate a continuous block of frequency domain resources for the transmission of multi-carrier signals and / or channels by configuring the offset and / or the bandwidth of the aggregated frequency band or carrier, and / or the frequency domain position of the PRB0 corresponding to the carrier of the detected SSB and the offset from the PRB0 corresponding to the carrier of the detected SSB to the starting position of the multi-carrier frequency domain resource. The offset can be configured so that each frequency band or carrier within the set of aggregated frequency bands or carriers uses the same offset, or the first carrier uses the offset;

[0112] • Maximum output power Pmax. Optionally, the maximum output power of the signal and / or channel on the frequency band or carrier within the set of aggregated frequency bands or carriers is the same, equal to the configured maximum output power. This operation is more suitable for UEs using the same radio frequency (RF) to receive signals and / or channels transmitted on more than one carrier;

[0113] • Subcarrier spacing. Optionally, the subcarrier spacing of signals and / or channels on the frequency bands or carriers within the set of aggregated frequency bands or carriers is the same, equal to the configured subcarrier spacing. This operation is more suitable for UEs using the same radio frequency (RF) to receive signals and / or channels transmitted on more than one carrier;

[0114] • Cyclic prefix. Optionally, the cyclic prefixes on the frequency bands or carriers within the set of aggregated frequency bands or carriers are the same, equal to the configured cyclic prefix. This operation is more suitable for UEs using the same radio frequency (RF) to receive signals and / or channels transmitted on more than one carrier;

[0115] • Control resource set 0 controlResourceSetZero and search space 0 searchSpaceZero;

[0116] A control resource set for indicating frequency domain resources for signal and / or channel transmission. The signal and / or channel includes data signals and / or channels, and control signals and / or channels. In one implementation, the frequency domain resources for signal and / or channel transmission within the set of aggregated frequency bands or carriers can be indicated by the control resource set, the value of which is a bitmap indicating whether the frequency domain resources are used. For example, starting from the beginning of the frequency domain resources, the leftmost bit of the bitmap is associated with the index of the first RB group or the first I RB groups or ARFCN or carrier within the bandwidth of the aggregated frequency band or carrier, from bottom to top, and so on. A bit value of 1 indicates that the carrier-mapped frequency domain resources corresponding to the associated RB group or ARFCN or carrier index within the set of aggregated frequency bands or carriers can be used, and a bit value of 0 indicates that the carrier-mapped frequency domain resources corresponding to the associated RB group or ARFCN or carrier index within the set of aggregated frequency bands or carriers are not used. This operation allows for more flexible scheduling of frequency domain resources on multiple carriers.

[0117] A control resource set for indicating frequency domain resources for control signal and / or channel transmission. In one implementation, control signals and / or channels are transmitted only on the first carrier. The frequency domain resources for transmitting control signals and / or channels can be indicated by a configured control resource set. The value of the control resource set is a bitmap indicating whether frequency domain resources are used. Starting from the beginning of the frequency domain resources, the leftmost bit of the bitmap is associated with the index of the first RB group or the first I RB groups or ARFCN or the carrier within the set of aggregated frequency bands or carriers, from bottom to top within the first carrier, and so on. A bit value of 1 indicates that the carrier-mapped frequency domain resources corresponding to the associated RB group or ARFCN or the carrier index within the set of aggregated frequency bands or carriers can be used, and a bit value of 0 indicates that the carrier-mapped frequency domain resources corresponding to the associated RB group or ARFCN or the carrier index within the set of aggregated frequency bands or carriers are not used. This operation restricts the transmission of control signals or channels to a control resource set of one frequency band or carrier, reducing the collision probability of multi-carrier signal transmission and ensuring the reliability of control signal transmission.

[0118] The downlink data channel common configuration parameter pdsch-ConfigCommon includes a downlink data channel time domain allocation list pdsch-TimeDomainAllocationList. This list configures the time domain offset value k0 from receiving downlink scheduling information (DCI) to receiving the downlink data channel. If k0 is missing or not configured, k0 defaults to r, where r is a predefined or preconfigured parameter value representing the number of time slots or OFDM symbols, and r is greater than 0. This operation takes into account the RF adjustment time of the UE receiving PDCCH from a first carrier and then receiving PDSCH from one or more other carriers, where one or more carriers can be one or more carriers associated with a cell.

[0119] The common configuration parameter `rach-ConfigCommon` for random access includes the number of frequency division multiplexing resources (`msg1-FDM`) for random access message 1, the frequency start position (`msg1-FrequencyStart`) for random access message 1, the threshold value of RSRP based on SSB measurement (`rsrp-thresholdSSB`), and the subcarrier spacing (`msg1-SubcarrierSpacing`) for random access message 1. The threshold value of RSRP based on SSB measurement applies to the measurement result of RSRP based on SSB measurement of the first carrier, or it applies to the RSRP measurement result based on CD-SSB or NCD-SSB on each frequency band or carrier within the set of aggregated frequency bands or carriers. For example, if the RSRP based on CD-SSB or NCD-SSB on any frequency band or carrier is lower than the threshold value `rsrp-thresholdSSB`, the frequency band or carrier is not used for the transmission of signals or channels used for aggregation. The subcarrier spacing configured in the random access message 1 is applied to access timing RO resources on all frequency bands or carriers within the set of aggregated frequency bands or carriers. These access timing RO resources share the same subcarrier spacing configuration. The frequency start position of the random access message 1 can be represented as the offset of the start position of the RO resource relative to the start position of the PRB0 or ​​multi-carrier frequency domain resource associated with the carrier that detected the SSB. The UE determines the start position of the RO resource using the start position of the PRB0 or ​​multi-carrier frequency domain resource and the msg1-FrequencyStart, and determines the number of RO resources on more than one frequency band or carrier using msg1-FDM. This operation allows UEs supporting multiple carriers for signal and / or signal transmission within a cell to use more RO resources to transmit msg1.

[0120] The common configuration parameter `pusch-ConfigCommon` for the uplink data channel includes a time offset `k2` from the time slot for scheduling the PDCCH to the starting time slot for transmitting the PUSCH. `k2` should further include an RF adjustment time, which can be a predefined or preconfigured number of time slots or OFDM symbols. This operation additionally considers the RF adjustment time from when the UE receives the PDCCH from a first carrier to when it transmits the PUSCH from one or more other carriers, which can be one or more carriers associated with a cell.

[0121] The value of I in the I RB group can be a pre-configured or predefined integer, where I is greater than or equal to 1. This operation is because the number of carriers in the aggregated frequency band or carrier set is large and the frequency range occupied is large, which is more than the number of frequency domain resources of a single bandwidth or carrier. In order to improve the efficiency of resource indication and reduce the number of bits of resource indication, multiple consecutive RBs can be combined together for simultaneous indication.

[0122] The purpose of indicating that a cell is associated with multiple carriers through a set of first configuration parameters is to address the fact that BWP is limited to only one frequency band and carrier, and the transmission of signals and / or channels is restricted to one frequency band or carrier, resulting in relatively large initial access and / or random access delays. This operation can reduce the initial access and / or random access delays on the terminal side and improve network throughput. Configuring multiple sets of first configuration information can improve flexibility and is suitable for different transmission scenarios and information transmission rates.

[0123] In one embodiment, the UE can obtain multiple sets of UE-specific second configuration information through RRC messages. Based on the indication of DCI or MAC CE, the UE determines a set of UE-specific second configuration information for the transmission of control signals and / or channels and / or data signals and / or channels on one or more associated carriers or frequency bands. If the UE does not receive the indication of DCI or MAC CE, the UE determines a set of UE-specific second configuration information as the default second configuration information. The default second configuration information can be the first set or the second configuration information with index 0. Alternatively, if the UE does not receive the indication of DCI or MAC CE, the UE determines the resources of control signals and / or channels, and / or data signals and / or channels on one or more carriers associated in the same cell based on the configuration of the first configuration information. The RRC message can be a CCCH message carried by Msg4 for establishing an RRC link. This operation allows the frequency domain resources of control signals and / or channels and data signals and / or channels to be different. By configuring the transmission resources of control signals and / or channels and data signals and / or channels separately, more flexible data transmission can be achieved, especially suitable for different data service types.

[0124] In one implementation, a set of second configuration information may include configuration information for uplink signals and / or channels and configuration information for downlink signals and / or channels, wherein the configuration information for uplink signals and / or channels and the configuration information for downlink signals and / or channels include control signals and / or channels and data signals and / or channels. The logical relationship of the parameters included in the set of second configuration information is as follows: Figure 7 As shown, a set of the second configuration information may include at least one of the following:

[0125] • The list of candidate aggregation bands or carriers;

[0126] • The offset from the PRB0 corresponding to the carrier of the detected SSB to the starting position of the frequency domain resource;

[0127] • The bandwidth of the aggregated frequency band or carrier. This operation can change the transmission bandwidth of the signal and / or channel by indicating different second configuration information;

[0128] • The offset of PRB0 from PointA on each aggregated frequency band or carrier within the set of aggregated frequency bands or carriers;

[0129] • The maximum output power Pmax;

[0130] • The subcarrier spacing

[0131] • The cyclic prefix

[0132] • Downlink data channel configuration information pdsch-config;

[0133] The downlink control channel configuration information (pdcch-config) includes a control resource set configuration (ControlResourceSet) containing indications for frequency domain resources (frequencyDomainResources). The values ​​of these frequency domain resources are bitmaps indicating whether they are being used. For example, starting from the beginning of the frequency domain resources, the leftmost bit of the bitmap is associated with the index of the first RB group, the first I RB groups, the ARFN, or the carrier within the aggregated frequency band or carrier set, from bottom to top within the bandwidth of the aggregated frequency band or carrier. A bit value of 1 indicates that the carrier-mapped frequency domain resource corresponding to the associated RB group, ARFN, or carrier index within the aggregated frequency band or carrier set can be used; a bit value of 0 indicates that the carrier-mapped frequency domain resource corresponding to the associated RB group, ARFN, or carrier index within the aggregated frequency band or carrier set is not used. This operation allows for more flexible scheduling of frequency domain resources across multiple carriers.

[0134] The uplink control channel configuration information (pucch-config) includes uplink control channel resources (PUCCH-resource) and uplink control channel format (PUCCH format). The PUCCH-resource indicates the frequency domain position of the starting PRB through PRB indexes or RB group indexes and / or ARFCN or the index of carriers within the aggregated frequency band or carrier set. The PRB indexes or RB group indexes are determined based on multiple frequency bands or carriers within the configured aggregated frequency band or carrier set. The PRB indexes or RB group indexes are continuous across multiple frequency bands or carriers, and the starting position of PRB0 or ​​RB group0 can be the frequency domain starting position of the first carrier PRB0. The PUCCH format indicates the number of PRBs or I RB groups in the frequency domain bandwidth. Indicating the frequency domain resource bandwidth based on the number of I RB groups is because the aggregated frequency band or carrier set has a large number of carriers and occupies a large frequency range, exceeding the frequency domain resource count of a single bandwidth or carrier. To improve resource indication efficiency and reduce the number of bits indicated, multiple consecutive RBs can be combined and indicated simultaneously.

[0135] The uplink data channel configuration information, pusch-config, includes the uplink data channel power control parameter pusch-PowerControl. This power control parameter determines the P0 and alpha values ​​for signal or channel transmission on aggregated carriers. For example, if the P0 and alpha values ​​are the same on bands or carriers within the aggregated set, they are equal to the configured P0 and alpha values. The pusch-config also includes an uplink data channel time domain resource allocation list pusch-TimeDomainAllocationList. This list indicates the time offset k2 between the time slot for scheduling the PDCCH and the starting time slot for transmitting the PUSCH. k2 should further include RF adjustment time, which can be a predefined or preconfigured number of time slots or OFDM symbols. This operation additionally considers the RF adjustment time from when the UE receives the PDCCH from a first carrier to when it transmits the PUSCH from one or more carriers, which can be one or more carriers associated with a cell.

[0136] • Serving cell downlink control channel configuration information PDCCH-ServingCellConfig. The PDCCH-ServingCellConfig includes a slot format indicator (SlotFormatIndicator). Optionally, the slot format indicators on the bands or carriers within the aggregated set of frequency bands or carriers are identical, equal to the configured slot format indicator. This operation is more suitable for UEs using the same radio frequency (RF) to receive signals and / or channels transmitted on more than one carrier.

[0137] • Serving cell downlink data channel configuration information pdsch-ServingCellConfig. The pdsch-ServingCellConfig includes the cell pucch-cell associated with the uplink control channel and / or the carrier indication for PUCCH transmission. The pucch-cell indicates the serving cell ID for PUCCH transmission, and the carrier indication value is the carrier index for PUCCH transmission. The UE determines the frequency domain resources for transmitting PUCCH based on the carrier associated with the PUCCH transmission carrier index and the uplink control channel configuration information. The carrier index is determined based on the configuration order within the set of aggregated frequency bands or carriers. Optionally, when adding a new carrier for PUCCH transmission to an associated cell, the pdsch-ServingCellConfig should be configured to indicate the frequency domain resources for PUCCH transmission. When updating the second configuration information, the pdsch-ServingCellConfig should be configured to indicate the frequency domain resources for PUCCH transmission.

[0138] The purpose of using a set of second configuration parameters to associate a cell with multiple carriers is to address the issue that BWPs are limited to a single frequency band and carrier, resulting in lower network throughput due to the restrictive nature of signal and / or channel transmission. This approach can reduce signal and / or channel transmission latency and improve network throughput. Configuring multiple sets of second configuration information enhances flexibility, making it suitable for different transmission scenarios and data transmission rates.

[0139] In one embodiment, based on multiple sets of first configuration information configured by SIB and / or indications of DCI or MAC CE, the UE can determine a set of cell-specific first configuration information for signal and / or channel transmission. Optionally, the signal and / or channel transmission can be signal and / or channel transmission on multiple carriers associated with a cell, which can reduce the initial access latency.

[0140] In one implementation, the UE determines that the DCI is being monitored in a common search space set. If CORESET0 is configured in a cell, the frequency domain resources being monitored are the frequency domain resources of CORESET0. If CORESET0 is not configured in a cell, the frequency domain resources being monitored are the frequency domain resources determined based on the first configuration information.

[0141] In one embodiment, based on multiple sets of second configuration information configured by RRC and / or indications of DCI or MAC CE, the UE can determine a set of UE-specific second configuration information for signal and / or channel transmission. Optionally, the signal and / or channel transmission can be for signal and / or channel transmission on multiple carriers associated with a cell. This approach allows for more flexible and rapid changes to configuration information, eliminating the need for RRC reconfiguration when changing transmission bandwidth, thus reducing handover latency and UE implementation complexity.

[0142] In one implementation, the UE determines that the DCI is being monitored in a common search space set. If CORESET0 is configured in a cell, the frequency domain resources being monitored are the frequency domain resources of CORESET0. If CORESET0 is not configured in a cell, the frequency domain resources being monitored are the frequency domain resources corresponding to the first carrier or the configured multi-carrier.

[0143] The DCI may include at least one of the following:

[0144] The DCI can be a RA-RNTI scrambled DCI in Random Access Message 2 (Msg2). Optionally, this method is suitable for indicating a first set of configuration information to determine the resources of Msg3;

[0145] • The DCI can be a DCI configured to indicate second configuration information; alternatively, this approach is suitable for indicating a set of second configuration information for determining uplink data signal and / or channel resources.

[0146] The domain of the DCI includes at least one or more of the following combinations:

[0147] • First configuration information group index or second configuration information group index. Each first configuration information group index or second configuration information group index is associated with a value of an information group index. The association between the first configuration information group index or second configuration information group index and the index value is predefined and can be indicated using codepoints. For example, 3 bits can be used to indicate the first or second configuration information associated with 0 to 7, 000 represents the first first configuration information group index or second configuration information group index, and so on. This method can indicate a group of first configuration information group indexes or second configuration information group indexes with fewer bits, saving bits.

[0148] A set of aggregated frequency bands or carrier indices, comprising index values ​​corresponding to frequency bands or carriers in a list of candidate aggregated frequency bands or carriers indicated by the DCI or configured by the RRC. Based on the index values ​​and the list of candidate aggregated frequency bands or carriers, the UE determines one or more frequency bands or carriers for signal and / or channel transmission. This operation allows for more flexible indication of combinations of frequency bands or carriers for multi-carrier transmission. Alternatively, in one implementation, the UE determines the set of aggregated frequency bands or carriers as the first N frequency bands or carriers in the list of candidate aggregated frequency bands or carriers, where N can be predefined or preconfigured, and N is an integer greater than 1. This operation can determine one or more frequency bands or carriers for signal and / or channel transmission using a predefined or preconfigured method when the set of aggregated frequency bands or carrier indices is not indicated.

[0149] • Time Domain Resource Allocation (TDRA). If the value of TDRA is 0, it indicates that the common configuration parameters of the downlink data channel and / or the common configuration parameters of the uplink data channel indicated by the first configuration parameter are used. If the value of TDRA is not 0, the UE can determine the associated k0, the mapping type of PDSCH, and the time domain start point and length SLIV based on the value of TDRA, or determine the associated k2, the mapping type of PUSCH, and the time domain start point and length SLIV. Based on the pdsch-config and / or pusch-config and TDRA in the first configuration information or the specified second configuration information, the UE determines the time domain resources on one or more frequency bands or carriers for PDSCH and / or PUSCH transmission. Optionally, the one or more frequency bands or carriers can be one or more frequency bands or carriers associated with a cell.

[0150] • Frequency Domain Resource Allocation (FDRA). The FDRA is used to indicate the location of frequency domain resources for signal or channel transmission scheduled by the DCI. The number of bits can be determined according to log2(N). rb (N rb Calculate +1) / 2), where N rb The bandwidth of the aggregated frequency band or carrier is determined based on the first configuration information and / or the indicated second configuration information, or by the sum of the bandwidths of the N frequency bands or carriers corresponding to the number N supported frequency bands or carriers, or by the sum of the bandwidths of the frequency bands or carriers associated with the set index corresponding to the aggregated frequency band or carrier index set indicated by the DCI. Optionally, when the DCI is monitored in a common search space set, N rb The bandwidth of the aggregated frequency band or carrier determined based on the first configuration information is determined when the DCI is monitored in a UE-specific search space set, N rb The bandwidth of the aggregated frequency band or carrier is determined based on the second configuration information.

[0151] The MAC CE may include at least one of the following:

[0152] The MAC CE can be the MAC CE carried in random access message 2 (Msg2). Optionally, this method is suitable for indicating a first set of configuration information to determine the resources of Msg3;

[0153] • The MAC CE can be a MAC CE configured to indicate second configuration information. Optionally, this approach is suitable for indicating a set of second configuration information used to determine uplink data signaling and / or channel resources;

[0154] The domain of the MAC CE includes at least one or more of the following combinations:

[0155] • Cell index, used to uniquely identify a cell;

[0156] • The index of the first configuration information group or the index of the second configuration information group. If the codepoint of the first configuration information group index or the second configuration information group index indicates the index value, it means that the first configuration information group or the second configuration information group associated with the index value is activated, and the first configuration information group or the second configuration information group associated with other index values ​​is deactivated;

[0157] A set of aggregated frequency bands or carrier indices, comprising index values ​​corresponding to frequency bands or carriers in one or more of the candidate aggregated frequency bands or carriers list. Based on the index values ​​and the list of candidate aggregated frequency bands or carriers, the UE determines one or more frequency bands or carriers for signal and / or channel transmission. This operation allows for more flexible indication of combinations of frequency bands or carriers used for multi-carrier transmission. Alternatively, in one implementation, the UE determines the set of aggregated frequency bands or carriers as the first N frequency bands or carriers in the list of candidate aggregated frequency bands or carriers, where N can be predefined or preconfigured, and N is an integer greater than 1. This operation can determine one or more frequency bands or carriers for signal and / or channel transmission using a predefined or preconfigured method when the set of aggregated frequency bands or carrier indices is not indicated.

[0158] In one implementation, the UE can update one or more configuration parameters in the first configuration information and / or the second configuration information via one or more of the RRC set-up signaling, RRC resume signaling, and RRC reconfiguration signaling. This operation can add and / or delete pre-configured first and / or second configuration information, or update a specific configuration parameter in the configuration information, increasing scheduling flexibility.

[0159] In one implementation, when the UE receives a DL MAC CE that activates a set of second configuration information, and when the UE transmits a PUCCH carrying HARQ-ACK information relative to the PDSCH carrying the DL MAC CE in slot Y, the UE should activate and / or apply the second configuration information from... The configuration information is applied starting from the first time slot thereafter, where μ is the subcarrier spacing configuration of the PUCCH, μ is equal to the subcarrier spacing configuration of the indicated set of first configuration information, or μ is equal to the subcarrier spacing configuration in the set of second configuration information applied before activating the set of second configuration information.

[0160] In one implementation, for unpaired spectrum, a second configuration information group index can be used to simultaneously indicate a set of downlink and uplink signals and / or channel-related second configuration information. This operation is possible because the uplink and downlink spectrum in the TDD band are at the same frequency. Using a second configuration information group index to simultaneously indicate a set of downlink and uplink signals and / or channel configuration information can reduce the number of bits required for indication and increase the efficiency of indication.

[0161] In one implementation, for paired spectrum, a second configuration information related to a set of downlink and uplink signals and / or channels can be simultaneously indicated by a second configuration information group index. This approach is based on the consideration that using a second configuration information group index to simultaneously indicate a set of downlink and uplink signal and / or channel configuration information can reduce the number of bits indicated and increase the efficiency of the indication.

[0162] In another implementation, for paired spectrum, a second configuration information group index can be used to indicate the configured downlink or uplink signal and / or channel-related second configuration information. This approach takes into account that the uplink and downlink spectrum in the FDD band are at different frequency points, and using a second configuration information group index to indicate the configuration information of the downlink or uplink signal and / or channel can improve the flexibility of indication.

[0163] In one embodiment, depending on the UE capability, if the UE supports transmitting signals and / or channels using multiple carriers, the transmission resources for random access Msg1 are determined based on the RO resources on the multiple carriers indicated by the first configuration information.

[0164] In one embodiment, depending on the UE capability, if the UE does not support transmitting signals and / or channels using multiple carriers, the transmission resources for random access to Msg1 are determined based on the RO resources in CORESET0 indicated by the first configuration information; if CORESET0 is not configured, the transmission resources for random access to Msg1 are determined on the carrier on which the SSB is detected to obtain access, or on the RO resources on the first carrier indicated by the first configuration information.

[0165] In one embodiment, the multicarrier may be a cell-associated multicarrier.

[0166] In one embodiment, if a first carrier is configured, a frequency band or carrier in the list of aggregated frequency bands or carriers associated with the index value indicated by the first carrier is determined as the first carrier; and / or a frequency band or carrier associated with the carrier index value of the indicated PUCCH transmission is determined as the first carrier for uplink transmission, wherein the carrier index value and the carriers or frequency bands in the list of aggregated frequency bands or carriers have a one-to-one correspondence; if the first carrier is not configured, the first carrier is the carrier that detects the SSB by default. Determining the first carrier by the indicated method allows the network to flexibly indicate the frequency domain position of the first carrier, while determining the first carrier by the default method ensures that when the first carrier index is not indicated, the UE and the network have a consistent understanding of the frequency or carrier range for receiving and transmitting the first carrier or control channel.

[0167] In one implementation, for unpaired spectrum, the first carrier for uplink transmission and the first carrier for downlink transmission are the same, which can be the carrier obtained by detecting the SSB. This method allows the uplink and downlink control channels to be transmitted on the same TDD spectrum, the uplink and downlink control channels have channel reciprocity, and the UE does not need to adjust the RF to transmit uplink control information.

[0168] In one implementation, for paired spectrum, the downlink transmission first carrier can be determined by a configured index value, or by default, by the carrier where an SSB is detected. The uplink transmission first carrier can be determined based on the first configuration information and / or the second configuration information; for example, determining one frequency band or carrier in the list of aggregated frequency bands or carriers associated with the index value of the carrier indication for PUCCH transmission as the uplink transmission first carrier. Alternatively, the uplink transmission first carrier can be determined by the unique uplink transmission first carrier associated with the downlink transmission first carrier. Determining the first carrier by indication allows the network to flexibly indicate the frequency domain location of the transmitted uplink control channel. Determining the first carrier by associating the downlink transmission first carrier with an uplink carrier helps the UE and the network to have a consistent understanding of the frequency or carrier range for receiving and transmitting the first carrier or control channel.

[0169] In one embodiment, depending on the UE capability, if the UE supports the use of multiple carriers to transmit signals and / or channels within a cell, the secondary carriers configured within the aggregated frequency band or carrier set, or carriers other than the first carrier, do not apply the configured BWP-related configuration information, but apply the BWP-related configuration information configured on the first carrier. That is, the BWP-related configuration information on the secondary carriers or carriers other than the first carrier is the same as the BWP-related configuration information configured on the first carrier.

The multiple sets of cell-specific first configuration information and / or multiple sets of UE-specific second configuration information are used to determine resources on one or more frequency bands or carriers for signal and / or channel transmission.

[0172] In step S802, the base station may send multiple sets of cell-specific first configuration information and / or send multiple sets of UE-specific second configuration information.
