Description

Methods and apparatus for receiving system information in wireless communication Technical Field

[0001] This application relates to transmission methods and apparatus in wireless communication systems, and more particularly to methods and apparatus for receiving system information. Background Technology

[0002] System Information (SI) consists of one Master Information Block (MIB) and multiple System Information Blocks (SIBs), categorized into Minimum SIs and Other SIs. The Minimum SI includes basic information required for initial access and information needed to acquire any other SIs. The Minimum SI comprises the MIB and SIB1. The MIB contains cell prohibition status information and the necessary physical layer information for receiving further system information (such as CORESET#0 configuration). The MIB is periodically broadcast on the BCH. SIB1 defines the scheduling of other System Information Blocks and contains information required for initial access. SIB1 is also known as the Remaining Minimum SI (RMSI), and it is periodically broadcast on the DL-SCH or sent in a dedicated manner on the DL-SCH to the User Equipment (REE) in RRC_CONNECTED. In NR (New Radio) systems, when a UE is in the RRC_CONNECTED state, it can only receive SIB1 on an active BWP (Bandwidth Part) with a common search space configured by searchSpaceSIB1 and pagingSearchSpace.

[0003] Existing carrier aggregation (CA) treats each component carrier (CC) as a serving cell. While existing carrier aggregation can improve the UE's service bandwidth and transmission rate, it has low efficiency in utilizing fragmented spectrum resources. Configuring multiple carriers for the same cell can not only leverage the advantages of existing carrier aggregation but also effectively improve the utilization efficiency of fragmented spectrum resources, making it an important evolution direction for future wireless communication technologies (such as 5G+ or 6G).

[0004] In existing technologies, the BSR (Buffer Status Report) process is used to provide the serving base station with information on the uplink (UL) data volume in the MAC (Medium Access Control) entity. Specifically, each logical channel is assigned to a logical channel group (LCG). When the BSR is triggered, the user equipment (UE) sends a BSR MAC CE (Control Element) to the base station, indicating the total amount of data in all logical channels of the corresponding LCG. The auxiliary serving base station schedules uplink resources for the UE based on the BSR MAC CE.

[0005] In NR (New Radio) Release 18, research on AI (Artificial Intelligence) / ML (Machine Learning) technologies was initiated to explore their impact on system performance and design. AI / ML technologies may also play a crucial role in future 6G communications. Compared to traditional processing methods, AI / ML features training-based and / or inference-based approaches and / or deployment requirements. According to the 3GPP (3rd Generation Partnership Project) standard TS38.300, AI / ML models and algorithms extend beyond the scope of 3GPP. Summary of the Invention

[0006] The inventors discovered through research that when the UE is in the RRC_CONNECTED state, how to receive SIB1 if multiple carriers are configured in the same cell is a problem that needs to be studied.

[0007] To address the aforementioned problems, this application provides a solution. While SIB1 is used as an example in the problem description, this application is also applicable to scenarios such as MIB, other SIs, SSBs, or PBCHs, achieving similar technical effects to SIB1. Furthermore, adopting a unified design scheme for different scenarios helps reduce hardware complexity and cost. While multiple carriers configured in the same cell are used as an example in the problem description, this application does not limit the name used for configuring multiple carriers in the same cell; for example, multiple carriers configured in the same cell can be called SCMC (Signal Cell Multiple Carrier). In addition, adopting a unified solution for different scenarios helps reduce hardware complexity and cost.

[0008] When using AI / ML coding, the existing BSR process can lead to an inappropriate amount of data provided to the serving base station, which is not conducive to the serving base station's scheduling of uplink resources. Therefore, it is necessary to enhance the data reporting mechanism.

[0009] To address the aforementioned problems, this application provides a solution. It should be noted that while the uplink is used as an example in the problem description above, this application is also applicable to scenarios such as physical layer information of sidelinks (SL) or IAB (Integrated Access and Backhaul) to achieve similar technical effects as the uplink. Although the initial intention of this application is to use AI / ML encoding, it is also applicable to traditional encoding methods other than AI / ML, achieving similar technical effects. Where there is no conflict, the embodiments and features in the first node of this application can be applied to the second node, and vice versa. Where there is no conflict, the embodiments and features in the embodiments of this application can be arbitrarily combined with each other.

[0010] As an example, the interpretation of terms in this application is based on the definitions in the 3GPP specification protocol TS38 series.

[0011] As an example, the interpretation of terms in this application is based on the definitions in the 3GPP specification protocol TS37 series.

[0012] It should be noted that, unless otherwise specified, the embodiments and features in any node of this application can be applied to any other node. Furthermore, unless otherwise specified, the embodiments and features in any embodiment of this application can be arbitrarily combined with each other.

[0013] This application discloses a method used in a first node for wireless communication, characterized by comprising:

[0014] Receive a first message, wherein the first message configures multiple frequency units for a first cell;

[0015] Receive system information of the first cell on the first frequency unit;

[0016] In response to at least the first frequency unit receiving quality being worse than or less than a first threshold, a first signaling is transmitted;

[0017] Receive second signaling;

[0018] The second signaling indicates that system information of the first cell is received on the second frequency unit, and the first frequency unit and the second frequency unit are two different frequency units among the plurality of frequency units.

[0019] In the above method, considering the differences in reception quality on different frequency units, when the reception quality of the first frequency unit used to receive the system information of the first cell deteriorates, a first signaling is sent to the network, thereby assisting the network in updating the frequency unit for receiving the system information of the first cell to the second frequency unit through a second signaling, thereby improving the reception performance of the system information of the first cell.

[0020] As one example, the first signaling is used to trigger the second signaling.

[0021] As one embodiment, the first signaling indicates the frequency unit for transmitting the second signaling.

[0022] As one embodiment, the first signaling is used to trigger the second signaling and the first signaling indicates the frequency unit for transmitting the second signaling.

[0023] As one embodiment, the first signaling is used to trigger the second signaling and the first signaling indicates at least one frequency unit.

[0024] As one embodiment, the first signaling indicates a frequency unit for transmitting the second signaling and the first signaling indicates at least one frequency unit.

[0025] According to one aspect of this application, the reception quality of the second frequency unit is better than or no worse than a second threshold; wherein the first signaling indicates the second frequency unit.

[0026] After receiving the first signaling, determining on which frequency unit the first node should receive the system information of the first cell is a problem that needs to be solved. The above method uses the first signaling to indicate a second frequency unit with reception quality better than or no worse than a second threshold, and the auxiliary network uses the second signaling to indicate on the second frequency unit to receive the system information of the first cell, thus ensuring the reception performance of the system information of the first cell.

[0027] In the above method, by reasonably configuring the first threshold and the second threshold, it can be ensured that the reception quality of the second frequency unit is better than that of the first frequency unit.

[0028] According to one aspect of this application, it is characterized by comprising:

[0029] Whenever the reception quality of the first frequency unit is worse than or less than the first threshold, the first counter increments by 1;

[0030] Wherein, the reception quality of at least the first frequency unit being worse than or less than a first threshold includes: the first counter reaching the first threshold, wherein the first threshold is a positive integer.

[0031] Determining whether the reception quality of at least the first frequency unit is worse than or less than a first threshold is a problem that needs to be solved. The above method, by introducing a first counter, helps to reduce the reporting frequency and signaling overhead of the first node.

[0032] According to one aspect of this application, the second signaling instructs the anchor frequency unit of the first cell to switch from the first frequency unit to the second frequency unit.

[0033] In the above method, considering the differences in reception quality on different frequency units, when the reception quality of the first frequency unit used to receive system information of the first cell deteriorates, a first signaling is sent to the network, thereby assisting the network in switching the anchor frequency unit of the first cell from the first frequency unit to the second frequency unit through a second signaling, thus ensuring the service performance of the first node in the first cell.

[0034] According to one aspect of this application, the step of receiving system information of the first cell on a first frequency unit includes: receiving system information of the first cell on the first frequency unit at a timing appropriate for receiving system information of the first cell; the step of receiving system information of the first cell on a second frequency unit includes: receiving system information of the first cell on the second frequency unit at a timing appropriate for receiving system information of the first cell; the timing appropriate for receiving system information of the first cell includes time domain resources and frequency domain resources.

[0035] According to one aspect of this application, it is characterized by comprising:

[0036] Receive a third signaling message, which instructs the anchor frequency unit of the first cell to switch from the second frequency unit to the third frequency unit;

[0037] In response to the receipt of the third signaling, the reception of system information from the first cell is stopped;

[0038] The third frequency unit is a frequency unit that is different from the first frequency unit and the second frequency unit among the plurality of frequency units; the third frequency unit is not configured for receiving system information of the first cell.

[0039] In the above method, the anchor frequency unit of the first cell does not need to be configured for receiving system information of the first cell. Furthermore, the first node receives the system information of the first cell only on the anchor frequency unit of the first cell, which is beneficial for more flexible adjustment of the anchor frequency unit while avoiding overly dynamic reception of system information of the first cell and reducing UE power consumption.

[0040] According to one aspect of this application, it is characterized by comprising:

[0041] Receive a third signaling instruction that the anchor frequency unit of the first cell is switched from the second frequency unit to the third frequency unit; in response to the receipt of the third signaling, receive system information of the first cell on a frequency unit other than the third frequency unit among the plurality of frequency units;

[0042] The third frequency unit is a frequency unit that is different from the first frequency unit and the second frequency unit among the plurality of frequency units; the third frequency unit is not configured for receiving system information of the first cell.

[0043] In the above method, the anchor frequency unit of the first cell does not need to be configured for receiving system information of the first cell; the first node can receive system information of the first cell on a non-anchor frequency unit, which is not only beneficial for flexibly adjusting the anchor frequency unit, but also for timely receiving system information of the first cell.

[0045] In response to the receipt of the second signaling, the reception of system information of the first cell on the first frequency unit is stopped, and the system information of the first cell is received on the second frequency unit.

[0046] The above method avoids receiving system information from the first cell on multiple frequency units, which helps to reduce the power consumption of the first node.

[0047] According to one aspect of this application, the first message includes a plurality of scheduling information blocks, each of which is associated with a plurality of frequency units, and each of the plurality of scheduling information blocks includes scheduling parameters of the system information of the first cell.

[0050] Wherein, the first UE capability indicates that the first node supports configuring more than one frequency unit for the same cell; the first message is that configuring the multiple frequency units for the first cell depends on the first UE capability.

[0051] The above methods facilitate consistency in understanding between the UE and the network, and avoid unreasonable configurations.

[0052] According to one aspect of this application, the second signaling instructs the deactivation of the first frequency unit; the first frequency unit is activated before the second signaling is received.

[0053] The above method does not release the configuration information of the first frequency unit, which is beneficial for dynamically activating the first frequency unit.

[0054] According to one aspect of this application, the second signaling indicates the release of configuration information of the first frequency unit.

[0055] The above method allows for timely release of frequency units, which is beneficial for network configuration.

[0056] According to one aspect of this application, the second signaling indicates that the first frequency unit is used as a non-anchor frequency unit.

[0057] The above method guarantees the frequency resources of the first node and avoids reducing the service quality of the first node.

[0062] Send a second signaling message;

[0063] Wherein, the second signaling indicates receiving system information of the first cell on the second frequency unit, and the first frequency unit and the second frequency unit are two different frequency units among the plurality of frequency units;

[0064] Wherein, the first signaling is used to trigger the second signaling; or, the first signaling indicates the frequency unit for transmitting the second signaling.

[0065] According to one aspect of this application, the reception quality of the second frequency unit is better than or no worse than a second threshold; wherein the first signaling indicates the second frequency unit.

[0066] According to one aspect of this application, a first counter is incremented by 1 whenever the reception quality of the first frequency unit is worse than or less than the first threshold; wherein, the reception quality of at least the first frequency unit being worse than or less than the first threshold includes: the first counter reaching the first threshold, where the first threshold is a positive integer.

[0079] Wherein, the first UE capability indicates that the sender of the first signaling supports configuring more than one frequency unit for the same cell; the first message configures the multiple frequency units for the first cell based on the first UE capability.

[0080] According to one aspect of this application, the second signaling instructs the deactivation of the first frequency unit; the first frequency unit is activated before the second signaling is received.

[0097] The data reporting mechanism has been enhanced.

[0098] To address the aforementioned problems, this application provides a solution. It should be noted that while the uplink is used as an example in the problem description above, this application is also applicable to scenarios such as physical layer information of sidelinks (SL) or IAB (Integrated Access and Backhaul) to achieve similar technical effects as the uplink. Although the initial intention of this application is to use AI / ML encoding, it is also applicable to traditional encoding methods other than AI / ML, achieving similar technical effects. Where there is no conflict, the embodiments and features in the first node of this application can be applied to the second node, and vice versa. Where there is no conflict, the embodiments and features in the embodiments of this application can be arbitrarily combined with each other.

[0099] As an example, the interpretation of terms in this application is based on the definitions in the 3GPP specification protocol TS38 series.

[0100] As an example, the interpretation of terms in this application is based on the definitions in the 3GPP specification protocol TS37 series.

[0101] This application discloses a method used in a first node for wireless communication, characterized by comprising:

[0102] Receive the first signaling;

[0103] Send a second signaling instruction; wherein the second signaling instruction indicates the amount of data on the first channel;

[0104] The second signaling indicates that the amount of data on the first channel depends on at least the first encoder; the first signaling indicates that the first encoder is applied to the encoding of the data on the first channel.

[0105] In existing technologies, the amount of data reported by the UE is independent of the encoder. Considering that changes in the information source or channel can affect the bit rate of the AI / ML encoder, when the bit rate of the AI / ML encoder is relatively dynamic, it further affects the size of the resources occupied by the data on the channel using the AI / ML encoder. If the amount of data reported by the UE is inappropriate, it will lead to too much or too little network scheduling resources, resulting in resource waste or scheduling delay. The above method solves the above problems by indicating through the second signaling that the amount of data on the first channel depends on at least the first encoder. The above method considers the impact of the encoder on the amount of data reported, which is conducive to reporting an appropriate amount of data to the network, further improving resource scheduling performance and transmission performance.

[0106] According to one aspect of this application, it includes:

[0107] Trigger a status report;

[0108] The sending of the second signaling depends on at least one pending status report; the second signaling is a MAC CE.

[0109] Determining how to send the second signaling is a technical problem that needs to be solved. The above method solves this problem by relying on at least one pending status report to send the second signaling, which is beneficial to the transmission of the second signaling. Furthermore, implementing the second signaling through MAC CE is beneficial to dynamically reporting the amount of data and improving the efficiency of data reporting.

[0110] According to one aspect of this application, it includes:

[0111] As a response to the first encoder being unavailable, cancel a pending status report;

[0112] The sending of the second signaling depends on at least one pending status report.

[0113] Based on the fact that there is at least one pending status report depending on the sending of a second signaling, how to cancel the pending status report is a technical problem that needs to be solved. The above method takes into account that the encoder is based on training and may become unavailable. In the case that the first encoder is unavailable, the first encoder cannot be applied to perform encoding. By canceling a pending status report as a response to the unavailability of the first encoder, the above problem is solved and unnecessary data reporting is avoided.

[0114] According to one aspect of this application, it includes:

[0115] In response to the first encoder being unavailable and having a pending status report, a BSR is triggered;

[0116] The sending of the second signaling depends on at least one pending status report.

[0117] The above method takes into account that the encoder is based on training and may become unavailable. How to handle the situation when the first encoder is unavailable is a technical problem that needs to be solved. Considering that if the UE still reports a status report even when the first encoder is unavailable, the network will schedule based on the first encoder. Inconsistencies in understanding between the UE and the network can lead to reduced encoding efficiency or decoding errors. The above method solves this problem by triggering a BSR (Browser Response Scheduler) as a response to the first encoder being unavailable and having an unresolved status report. Furthermore, the above method implicitly indicates the unavailability of the first encoder through the BSR, which is beneficial for assisting subsequent network scheduling.

[0118] According to one aspect of this application, it includes:

[0119] In response to the first encoder being unavailable and having a pending status report, cancel the pending status report and trigger a BSR;

[0120] The sending of the second signaling depends on at least one pending status report.

[0121] According to one aspect of this application, it is characterized by comprising:

[0122] Receive a third signaling message, the third signaling message indicating the scheduling information of the first wireless channel;

[0123] Transmit the first wireless channel;

[0124] Wherein, the bits transmitted on the first wireless channel include the output of the data on the first channel encoded by the first encoder; the scheduling information of the first wireless channel indicates at least one of the first channel or the first encoder.

[0125] Determining how to send data on the first channel of the first encoder using a network-scheduled wireless channel is a technical problem that needs to be solved. The above method solves the above problem by instructing at least one of the first channel or the first encoder through the scheduling information of the first wireless channel, which helps to ensure the transmission of data on the first channel.

[0126] According to one aspect of this application, it is characterized by comprising:

[0127] Perform resource allocation, wherein performing resource allocation includes prioritizing the allocation of resources to the first channel;

[0128] The priority allocation of resources to the first channel depends on the encoding of the data applied to the first channel by the first encoder.

[0129] When the first encoder is applied to the encoding of data on the first channel, how to perform resource allocation is a technical problem that needs to be solved; the above method solves the above problem by prioritizing the allocation of resources to the first channel where the first encoder is applied; the above method also helps to improve transmission efficiency.

[0130] According to one aspect of this application, the second signaling indicates the characteristics of the data on the first channel.

[0131] The above method takes into account the influence of the characteristics of the data on the first channel on the encoding of the first encoder. By indicating the characteristics of the data on the first channel through the second signaling, it is helpful for the auxiliary network to determine the parameters of the first encoder.

[0132] According to one aspect of this application, the second signaling includes a first field indicating the amount of data on the first channel; wherein the value of the first field depends on the amount of data on the first channel and a first adjustment factor; the first adjustment factor is used by the first encoder for encoding.

[0133] How to indicate the amount of data on the first channel in the second signaling is a technical problem that needs to be solved; in the above method, the value of the first field indicating the amount of data on the first channel takes into account the influence of the first adjustment factor, which is beneficial for reporting an appropriate amount of data on the network.

[0139] According to one aspect of this application, the receiver of the first signaling triggers a BSR in response to the first encoder being unavailable and having a pending status report; wherein the transmission of the second signaling depends on having at least one pending status report.

Figure 3 shows the radio protocol architecture for the control plane 300 in three layers: Layer 1, Layer 2, and Layer 3. Layer 1 (L1 layer) is the lowest layer and implements various PHY (Physical Layer) signal processing functions. The L1 layer will be referred to herein as PHY 301. Layer 2 (L2 layer) 305 is above PHY 301 and includes a MAC (Medium Access Control) sublayer 302, an RLC (Radio Link Control) sublayer 303, and a PDCP (Packet Data Convergence Protocol) sublayer 304. The PDCP sublayer 304 provides multiplexing between different radio bearers and logical channels. The PDCP sublayer 304 also provides security through encrypted data packets and provides cross-area mobility support. RLC sublayer 303 provides upper-layer packet segmentation and reassembly, retransmission of lost packets, and packet reordering to compensate for out-of-order reception caused by HARQ (Hybrid Automatic Repeat Request). MAC sublayer 302 provides multiplexing between the logical and transport channels. MAC sublayer 302 is also responsible for allocating various radio resources (e.g., resource blocks) within a cell. MAC sublayer 302 is also responsible for HARQ operations. RRC (Radio Resource Control) sublayer 306 in Layer 3 (L3) of the control plane 300 is responsible for acquiring radio resources (i.e., radio bearers) and using RRC signaling to configure the lower layers. The radio protocol architecture of user plane 350 includes Layer 1 (L1 layer) and Layer 2 (L2 layer). In user plane 350, the radio protocol architecture for physical layer 351, PDCP sublayer 354 in L2 layer 355, RLC sublayer 353 in L2 layer 355, and MAC sublayer 352 in L2 layer 355 is largely the same as the corresponding layers and sublayers in control plane 300. However, PDCP sublayer 354 also provides header compression for upper layer packets to reduce radio transmission overhead. L2 layer 355 in user plane 350 also includes SDAP (Service Data Adaptation Protocol) sublayer 356. SDAP sublayer 356 is responsible for mapping between QoS streams and data radio bearers (DRBs) to support service diversity.

[0857] Example 4

[0858] Embodiment 4 illustrates a schematic diagram of a first communication device and a second communication device according to this application, as shown in Figure 4. Figure 4 is a block diagram of a first communication device 450 and a second communication device 410 communicating with each other in an access network.

[0859] The first communication device 450 includes a controller / processor 459, a memory 460, a data source 467, a transmitting processor 468, a receiving processor 456, a multi-antenna transmitting processor 457, a multi-antenna receiving processor 458, a transmitter / receiver 454, and an antenna 452.

[0860] The second communication device 410 includes a controller / processor 475, a memory 476, a receiver processor 470, a transmitter processor 416, a multi-antenna receiver processor 472, a multi-antenna transmitter processor 471, a transmitter / receiver 418, and an antenna 420.

[0861] In the transmission from the second communication device 410 to the first communication device 450, at the second communication device 410, upper-layer data packets from the core network are provided to the controller / processor 475. The controller / processor 475 implements L2 layer functionality. In the transmission from the second communication device 410 to the first communication device 450, the controller / processor 475 provides header compression, encryption, packet segmentation and reordering, multiplexing between logical and transport channels, and radio resource allocation to the first communication device 450 based on various priority metrics. The controller / processor 475 is also responsible for retransmitting lost packets and signaling to the first communication device 450. The transmit processor 416 and the multi-antenna transmit processor 471 implement various signal processing functions for the L1 layer (i.e., the physical layer). Transmit processor 416 performs encoding and interleaving to facilitate forward error correction (FEC) at the second communication device 410, and mapping of signal clusters based on various modulation schemes (e.g., Binary Phase Shift Keying (BPSK), Quadrature Phase Shift Keying (QPSK), M-Phase Shift Keying (M-PSK), M-QAM). Multi-antenna transmit processor 471 performs digital spatial precoding on the encoded and modulated symbols, including codebook-based and non-codebook-based precoding, and beamforming processing, generating one or more spatial streams. Transmit processor 416 then maps each spatial stream to subcarriers, multiplexes it with a reference signal (e.g., a pilot) in the time and / or frequency domains, and subsequently uses inverse fast Fourier transform (IFFT) to generate a physical channel carrying the time-domain multicarrier symbol stream. Multi-antenna transmit processor 471 then performs transmit analog precoding / beamforming operations on the time-domain multicarrier symbol stream. Each transmitter 418 converts the baseband multicarrier symbol stream provided by the multi-antenna transmitter processor 471 into an radio frequency stream, which is then provided to different antennas 420.

[0862] In the transmission from the second communication device 410 to the first communication device 450, at the first communication device 450, each receiver 454 receives a signal through its corresponding antenna 452. Each receiver 454 recovers the information modulated onto the radio frequency carrier and converts the radio frequency stream into a baseband multicarrier symbol stream, which is then provided to the receiver processor 456. The receiver processor 456 and the multi-antenna receiver processor 458 implement various signal processing functions of the L1 layer. The multi-antenna receiver processor 458 performs receive analog precoding / beamforming operations on the baseband multicarrier symbol stream from the receiver 454. The receiver processor 456 uses a Fast Fourier Transform (FFT) to convert the baseband multicarrier symbol stream after the receive analog precoding / beamforming operations from the time domain to the frequency domain. In the frequency domain, the physical layer data signal and the reference signal are demultiplexed by the receiver processor 456, where the reference signal is used for channel estimation, and the data signal is recovered in the multi-antenna receiver processor 458 after multi-antenna detection to recover any spatial stream destined for the first communication device 450. Symbols on each spatial stream are demodulated and recovered in the receive processor 456, generating soft decisions. The receive processor 456 then decodes and deinterleaves the soft decisions to recover the upper-layer data and control signals transmitted by the second communication device 410 over the physical channel. The upper-layer data and control signals are then provided to the controller / processor 459. The controller / processor 459 implements the functions of Layer 2. The controller / processor 459 may be associated with a memory 460 storing program code and data. The memory 460 may be referred to as computer-readable media. In the transmission from the second communication device 410 to the first communication device 450, the controller / processor 459 provides multiplexing, packet reassembly, decryption, header decompression, and control signal processing between the transport and logical channels to recover upper-layer data packets from the core network. The upper-layer data packets are then provided to all protocol layers above Layer 2. Various control signals may also be provided to Layer 3 for Layer 3 processing.

[0863] In the transmission from the first communication device 450 to the second communication device 410, at the first communication device 450, a data source 467 is used to provide upper-layer data packets to the controller / processor 459. The data source 467 represents all protocol layers above the L2 layer. Similar to the transmission functions at the second communication device 410 described in the transmission from the second communication device 410 to the first communication device 450, the controller / processor 459 implements header compression, encryption, packet segmentation and reordering, and multiplexing between logical and transport channels based on radio resource allocation, implementing L2 layer functions for the user plane and control plane. The controller / processor 459 is also responsible for retransmitting lost packets and signaling to the second communication device 410. Transmit processor 468 performs modulation mapping and channel coding processing, while multi-antenna transmit processor 457 performs digital multi-antenna spatial precoding, including codebook-based and non-codebook-based precoding, and beamforming processing. Subsequently, transmit processor 468 modulates the generated spatial stream into a multi-carrier / single-carrier symbol stream. After analog precoding / beamforming operations in multi-antenna transmit processor 457, the stream is provided to different antennas 452 via transmitter 454. Each transmitter 454 first converts the baseband symbol stream provided by multi-antenna transmit processor 457 into a radio frequency symbol stream before providing it to antenna 452.

[0864] In the transmission from the first communication device 450 to the second communication device 410, the function at the second communication device 410 is similar to the receiving function at the first communication device 450 described in the transmission from the second communication device 410 to the first communication device 450. Each receiver 418 receives radio frequency signals through its corresponding antenna 420, converts the received radio frequency signals into baseband signals, and provides the baseband signals to the multi-antenna receiving processor 472 and the receiving processor 470. The receiving processor 470 and the multi-antenna receiving processor 472 jointly implement the L1 layer functions. The controller / processor 475 implements the L2 layer functions. The controller / processor 475 may be associated with a memory 476 that stores program code and data. The memory 476 may be referred to as computer-readable media. In the transmission from the first communication device 450 to the second communication device 410, the controller / processor 475 provides multiplexing between the transmission and logical channels, packet reassembly, decryption, header decompression, and control signal processing to recover upper-layer data packets from the UE 450. Upper-layer packets from the controller / processor 475 can be provided to the core network.

[0897] Example 5A

[0898] Example 5A illustrates a wireless signal transmission flowchart according to an embodiment of the present application, as shown in Figure 5A.

[0899] For the first node U01, in step S5101A, a first UE capability request is received; in step S5102A, first UE capability information is sent; wherein, the first UE capability indicates that the first node supports configuring more than one frequency unit for the same cell; the first message indicates that configuring the multiple frequency units for the first cell depends on the first UE capability; in step S5103A, a first message is received, wherein the first message indicates that configuring multiple frequency units for the first cell; in step S5104A, system information of the first cell is received on the first frequency unit; in step S5105A, as a response that the reception quality of at least the first frequency unit is worse than or less than a first threshold, a first signaling is sent; in step S5106A, a second signaling is received; in step S5107A, system information of the first cell is received on the second frequency unit.

[0900] For the second node N02, in step S5201A, the first UE capability request is sent; in step S5202A, the first UE capability information is received; in step S5203A, the first message is sent; in step S5204A, the system information of the first cell is sent on the first frequency unit; in step S5205A, the first signaling is received; in step S5206A, the second signaling is sent; and in step S5207A, the system information of the first cell is sent on the second frequency unit.

[0901] In Embodiment 5A, the second signaling indicates receiving system information of the first cell on the second frequency unit, wherein the first frequency unit and the second frequency unit are two different frequency units among the plurality of frequency units; wherein the first signaling is used to trigger the second signaling; or, the first signaling indicates the frequency unit transmitting the second signaling.

[0902] As an example, before the second signaling is received, the first node U01 receives the system information of the first cell on the first frequency unit; after the second signaling is received, the first node U01 receives the system information of the first cell on the second frequency unit.

[0903] As an example, before the second signaling is received, the first node U01 receives the system information of the first cell on only the former of the first frequency unit and the second frequency unit; after the second signaling is received, the first node U01 receives the system information of the first cell on only the latter of the first frequency unit and the second frequency unit.

[0904] As an example, before the second signaling is received, the first node U01 receives the system information of the first cell on only the first frequency unit among the plurality of frequency units; after the second signaling is received, the first node U01 receives the system information of the first cell on only the second frequency unit among the plurality of frequency units.

[0905] As an example, in step S5107A, in response to the receipt of the second signaling, the UE determines whether to continue receiving system information of the first cell on the first frequency unit and on the second frequency unit.

[0906] As an example, in step S5107A, in response to the receipt of the second signaling, the configuration information of the first frequency unit is released and the system information of the first cell is received on the second frequency unit; wherein, the second signaling indicates the release of the configuration information of the first frequency unit.

[0907] As an example, in step S5107A, in response to the receipt of the second signaling, the first frequency unit is activated and system information of the first cell is received on the second frequency unit; wherein, the second signaling indicates to activate the first frequency unit; the first frequency unit is activated before the second signaling is received.

[0908] As an example, in step S5107A, in response to the receipt of the second signaling, the first frequency unit is used as a non-anchor frequency unit and the system information of the first cell is received on the second frequency unit; wherein, the second signaling indicates that the first frequency unit is used as a non-anchor frequency unit.

[0909] As an example, in step S5107A, in response to the receipt of the second signaling, the reception of system information of the first cell on the first frequency unit is stopped and the system information of the first cell is received on the second frequency unit.

[0910] As an example, after the second signaling is received, the configuration of the first frequency unit for the timing of receiving system information of the first cell is released.

[0911] As an example, after the second signaling is received, the configuration of the first frequency unit for receiving system information of the first cell is not released.

[0912] As an example, before the second signaling is received, the second frequency unit is configured to receive system information of the first cell at the appropriate time.

[0913] As an example, before the first signaling is received, at least the first frequency unit and the second frequency unit among the plurality of frequency units are configured to receive system information of the first cell; after the first signaling is received, at least the second frequency unit among the plurality of frequency units is configured to receive system information of the first cell.

[0914] As an example, before the first signaling is received, each of the plurality of frequency units is configured for the timing of receiving system information of the first cell.

[0915] As an example, before the second signaling is received, the second frequency unit is not configured for receiving system information of the first cell; wherein, the second signaling is configured on the second frequency unit for receiving system information of the first cell.

[0916] As an example, before the first signaling is received, only the first frequency unit among the plurality of frequency units is configured as the timing for receiving system information of the first cell; after the first signaling is received, only the second frequency unit among the plurality of frequency units is configured as the timing for receiving system information of the first cell.

[0917] As an example, accompanied by the second signaling, the second node N02 stops transmitting the system information of the first cell on the first frequency unit and begins transmitting the system information of the first cell on the second frequency unit. This method is beneficial for network energy saving.

[0918] As one embodiment, before and after the second signaling is sent, the second node N02 sends the system information of the first cell on the first frequency unit and also sends the system information of the first cell on the second frequency unit. This method ensures that the UE on the first frequency unit receives the system information of the first cell on the first frequency unit, thereby avoiding any impact on the UE on the first frequency unit.

[0919] As an example, the dashed box F5.2A is present.

[0920] As a sub-example, the first node U01 supporting the configuration of more than one frequency unit for the same cell means that the first node U01 has the UE capability to configure more than one frequency unit for the same cell.

[0921] As a sub-implementation, the first UE capability information is a UECapabilityInformation message. This method enables the second node N02 to know the UE capabilities of the first node U01, avoiding the configuration of UE capabilities beyond those of the first node U01.

[0922] As a sub-example, the first node U01 supporting the configuration of more than one frequency unit for the same cell means that the first node U01 prefers to configure more than one frequency unit for the same cell.

[0923] As a sub-implementation, the first UE capability information is a UEAssistanceInformation message. This method facilitates the dynamic adjustment of UE capabilities and makes configuring multiple frequency units for the first cell more flexible.

[0924] As a sub-example, the first UE capability information assists the second node N02 in sending the first message.

[0925] As a sub-example, the number of the plurality of frequency units configured for the first cell in the first message does not exceed the maximum number of frequency units that the first node U01 supports for configuring for the same cell, as indicated by the first UE capability information.

[0926] As a sub-example, the first UE capability information indicates K1; K1 is the maximum number of frequency units configured for the same cell supported by the first node U01.

[0927] As a sub-implementation, K1 is the maximum number of intra-band frequency units configured for the same cell supported by the first node U01.

[0928] As a sub-implementation, K1 is the maximum number of inter-band frequency units configured for the same cell supported by the first node U01.

[0929] As a sub-example, configuring more than one frequency unit for the same cell includes: SCMC; the frequency unit refers to a carrier.

[0930] As a sub-example, configuring more than one frequency unit for the same cell includes: performing multi-frequency unit operation in the same cell.

[0931] As a sub-implementation, the dashed box F5.1A exists.

[0932] As an additional embodiment, the sending of the first UE capability information is performed in response to the receipt of the first UE capability request.

[0933] As an additional embodiment, the first UE capability request is a UECapabilityEnquiry message, and the first UE capability information is a UECapabilityInformation message.

[0934] As a sub-implementation, the dashed box F5.1A does not exist.

[0935] As an additional embodiment, the first node U01 performs the sending of the first UE capability information on its own.

[0936] As an additional embodiment, the first node U01 performs the sending of the first UE capability information based on the UE implementation.
