Description

Method and apparatus for receiving SIB1 messages used 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 SIB1 messages. Background Technology

[0002] Network energy efficiency is crucial for environmental sustainability, reducing environmental impact (greenhouse gas emissions), and saving operating costs. With the widespread adoption of 5G (5th Generation Mobile Communication Technology) across various industries and geographic regions, more advanced services and applications requiring extremely high data rates (such as XR) are developing, leading to denser networks using more antennas, larger bandwidths, and more frequency bands. The environmental impact of 5G needs to be controlled, necessitating the development of new solutions to improve network energy efficiency. Rel-18 introduces NR (New Radio) network power saving, mainly for RRC_CONNECTED state, user-specific signals and channels, and low-load scenarios. This includes enhancements to the cell DTX (Discontinuous Transmission) / DRX (Discontinuous Reception) mechanism, including alignment of cell DTX / DRX and UE DRX in RRC_CONNECTED mode, information exchange between cell DTX / DRX nodes, and spatial and power domain technologies to achieve effective adaptation of spatial elements and effective adaptation of power offset values ​​between PDSCH (Physical Downlink Shared Channel) and CSI-RS (Channel State Information Reference Signal). To further enhance energy efficiency, Rel-19 established a WI for network energy savings (NES) enhancement in NR, supporting on-demand SIB1 in RRC_INACTIVE and RRC_IDLE states. Specifically, the UE obtains the uplink WUS configuration of the NES cell by periodically sending its own SIB1 (System Information Block 1) messages on cell A, and sends WUS and receives on-demand SIB1 messages on the NES cell.

[0003] The ITU (International Telecommunication Union), in its recommendation "Framework and overall objectives of the future development of IMT for 2030 and beyond," outlined the requirements and use cases for 6G (6th Generation Mobile Communication Technology), with sustainability considered a universally applicable design principle across all use cases. Furthermore, 3GPP has also begun research on 6G use cases, proposing a use case on end-to-end energy efficiency improvement for the network and UE in TR 22.870, recognizing that supporting end-to-end energy efficiency is a crucial design objective for the sustainability of 6G systems.

[0004] In the NR (New Radio) system, the MIB (Master Information Block) message is mainly used to provide the basic parameters required for decoding the SIB1 (System Information Block 1) message. The MIB message is transmitted through the BCH (Broadcast Channel) and broadcast on the PBCH (Physical Broadcast Channel). The MIB message is always transmitted on the BCH with an 80ms change period and repeats within 80ms. Since the PBCH (Physical Broadcast Channel) payload includes the 4 bits of the least significant bit (LSB) of the SFN (System Frame Number), the 6 bits of the most significant bit (MSB) of the SFN will change once after 160ms.

[0005] The ITU (International Telecommunication Union) proposed the requirements and use cases for 6G (6th Generation Mobile Communication Technology) in its recommendation "Framework and overall objectives of the future development of IMT for 2030 and beyond". In addition, 3GPP has also begun to study 6G use cases. In TR 22.870, typical 6G use cases were proposed, including end-to-end energy efficiency improvement for the network and UE, AI (Artificial Intelligence), ISAC (Integrated Sensing and Communication), Ubiquitous Connectivity, Immersive Communication, and Massive Communication. Summary of the Invention

[0006] The inventors discovered through research that how to further reduce the impact of SIB1 messages on energy consumption is a problem that needs to be solved.

[0007] To address the above problems, this application provides a solution.

[0008] The inventors discovered through research that since the number of bits in the least significant bit and the most significant bit of the SFN included in the PBCH payload are fixed, and the change cycle of the MIB message is not flexible enough, it is not conducive to the diverse scenarios of future 6G. Therefore, it is necessary to enhance the SFN.

[0009] To address the above problems, this application provides a solution.

[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 TS36 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.

[0016] In existing technologies, if a cell does not have a suitable cell A, it cannot support on-demand SIB1. To further reduce the impact of SIB1 messages on energy consumption, the above method addresses this problem by indicating, through the first information block included in the first MIB message, the scheduling configuration of the SIB1 message and the configuration of the wake-up signal, at least the configuration of the wake-up signal. This method does not rely on cell A, avoids inter-cell interaction, facilitates independent energy saving, and improves energy efficiency.

[0023] Determining whether the configuration of the wake-up signal, or the scheduling configuration of the SIB1 message indicated by the first information block included in the first MIB message, is at least one of these is a problem that needs to be solved.

[0050] According to one aspect of this application, the first broadcast information block includes a first physical channel, and the first broadcast information block indicates the transmission power of the first physical channel included in the first broadcast information block.

[0051] According to one aspect of this application, the first broadcast information block includes a second physical channel, and the receiving parameters of the second physical channel of the first broadcast information block are determined by the receiver of the first broadcast information block to determine the configuration of the wake-up signal.

[0054] Sending SIB1 messages or scheduling configuration for SIB1 messages, at least one of the following;

[0055] During this process, the recipient of the first broadcast information block receives the SIB1 message along with the wake-up signal.

[0056] According to one aspect of this application, it is characterized by comprising:

[0057] Send the wake-up signal;

[0058] Sending SIB1 messages or scheduling configuration for SIB1 messages, at least one of the following;

[0059] During this process, the recipient of the first broadcast information block receives the SIB1 message along with the wake-up signal.

[0060] According to one aspect of this application, the recipient of the SIB1 message cancels the wake-up signal in response to the receipt of the SIB1 message.

[0061] According to one aspect of this application, the recipient of the SIB1 message cancels the wake-up signal in response to the DCI used to schedule the SIB1 message being received.

[0062] According to one aspect of this application, the configuration of the wake-up signal depends on the scheduling configuration of the SIB1 message; wherein the first information block included in the first MIB message indicates both the scheduling configuration of the SIB1 message and the configuration of the wake-up signal.

[0063] This application discloses a first node used for wireless communication, characterized in that it includes:

[0064] A first processor receives a first broadcast information block, wherein the first broadcast information block includes a first MIB message;

[0065] The first MIB message includes a first information block, which indicates at least one of the scheduling configuration of the SIB1 message and the configuration of the wake-up signal; the configuration of the wake-up signal includes at least one of the time-domain resources or frequency-domain resources occupied by the wake-up signal.

[0066] This application discloses a second node used for wireless communication, characterized by comprising:

[0067] The second processor sends a first broadcast information block, wherein the first broadcast information block includes a first MIB message;

[0068] The first MIB message includes a first information block, which indicates at least one of the scheduling configuration of the SIB1 message and the configuration of the wake-up signal; the configuration of the wake-up signal includes at least one of the time-domain resources or frequency-domain resources occupied by the wake-up signal.

[0069] This application discloses a method used in a first node for wireless communication, characterized by comprising:

[0070] A first broadcast message is received on a first broadcast channel of a first cell, wherein the first broadcast message includes a MIB message and a first bit group, the first bit group included in the first broadcast message indicates the least significant X1 bits of the SFN, where X1 is a positive integer, and the MIB message included in the first broadcast message indicates the most significant X2 bits of the SFN, where X2 is a positive integer.

[0071] The candidate X1 includes multiple positive integers, and the SFN is composed of the X1 bits and the X2 bits.

[0072] Considering that an excessively long change cycle for MIB messages would hinder MIB message updates, while an excessively short change cycle would impede UE reception of MIB messages, the above method utilizes the X1 bits of the least significant SFN indicated by the first bit group included in the first broadcast information. The X1 bits can be a candidate of multiple positive integers. By flexibly adjusting the number of the least significant bits of the SFN indicated by the first bit group included in the first broadcast information, this method helps balance MIB message updates and UE reception of MIB messages, thereby improving system performance.

[0073] According to one aspect of this application, the X2 is fixed.

[0074] In the above method, since the candidates for X1 include multiple positive integers and X2 is fixed, the number of bits of SFN can be flexibly adjusted to achieve a variable range of SFN, which is beneficial to support different scenarios and needs. For example, a longer SFN can support a longer paging or DRX cycle, improving power saving efficiency, while a shorter SFN is beneficial to reduce the overhead of SFN in broadcast information.

[0075] According to one aspect of this application, the sum of X1 and X2 is 10.

[0078] Determining X1 is a technical problem that needs to be solved; in the above method, X1 depends on the type of the first cell, which is beneficial to optimize X1 according to different cell types.

[0079] According to one aspect of this application, the first broadcast information includes a second bit group, wherein X1 depends on the second bit group included in the first broadcast information, and any bit in the second bit group included in the first broadcast information is not a bit in the first bit group included in the first broadcast information.

[0080] Determining X1 is a technical problem that needs to be solved. In the above method, X1 depends on the second bit group, which is simple to implement and facilitates the first node in determining X1.

[0081] According to one aspect of this application, the first bit group included in the first broadcast information is X3 bits, the maximum value of the candidate X1 is X3, and X3 is a positive integer.

[0082] Considering that an excessively large number of X1s would increase the unnecessary load on the broadcast channel, the above method solves this problem by limiting the maximum value of the candidates for X1, which helps to reduce the load on the broadcast channel.

[0083] According to one aspect of this application, when X1 is less than X3, at least one bit in the first bit group included in the first broadcast information indicates the type of the first cell.

[0084] The above method is conducive to making full use of the first broadcast information and providing more broadcast information.

[0088] The candidate X1 includes multiple positive integers, and the SFN is composed of the X1 bits and the X2 bits.

[0089] According to one aspect of this application, the X2 is fixed.

[0090] According to one aspect of this application, the sum of X1 and X2 is 10.

Figure 3 is a schematic diagram illustrating an embodiment of a radio protocol architecture for a user plane 350 and a control plane 300. 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.

[0367] Example 4

[0368] 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.

[0369] 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.

[0370] 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.

[0371] 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.

[0372] 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.

[0373] 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.

[0374] 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.

[0677] As an example, if at least the second information block included in the first broadcast information block is set to a first value, the first information block included in the first MIB message indicates only the configuration of the wake-up signal, which is either the scheduling configuration of the SIB1 message or the configuration of the wake-up signal; if the second information block included in the first broadcast information block is not set to the first value, the first information block included in the first MIB message indicates only the scheduling configuration of the SIB1 message, which is either the scheduling configuration of the SIB1 message or the configuration of the wake-up signal.

[0678] As an example, if at least the second information block included in the first broadcast information block is set to a first value, the first information block included in the first MIB message indicates the scheduling configuration of the SIB1 message and the configuration of the wake-up signal; if the second information block included in the first broadcast information block is not set to the first value, the first information block included in the first MIB message indicates only the scheduling configuration of the SIB1 message, either the scheduling configuration of the SIB1 message or the configuration of the wake-up signal.

[0679] As an example, the statement that at least the second information block included in the first broadcast information block is set to a first value means that the second information block included in the first broadcast information block is set to a first value.

[0680] As an example, the statement that at least the second information block included in the first broadcast information block is set to a first value means that the second information block included in the first broadcast information block is set to a first value and the carrier frequency for obtaining the first MIB message is a first carrier frequency.

[0681] As an example, the statement that the second information block included in at least the first broadcast information block is set to a first value means that the second information block included in the first broadcast information block is set to a first value and the subcarrier spacing indicated by the first MIB message is a first subcarrier spacing.

[0682] As one embodiment, the second information block included in the first broadcast information block indicates the type of the first cell; the first value indicates that the first cell is of a first type, and the second value indicates that the first cell is of a second type.

[0683] As an example, the second information block included in the first broadcast information block not being set to the first value means that the second information block included in the first broadcast information block is set to a second value; wherein the second value is different from the first value.

[0684] As an example, the first value is a code point.

[0685] As an example, the first value is true.

[0694] Example 7B

[0695] Example 7B illustrates a schematic diagram of a first bit group included in a first broadcast message according to an embodiment of this application, as shown in Figure 7B. In Figure 7B, each solid-line box represents one bit.

[0696] In embodiment 7B, the first bit group included in the first broadcast information is X3 bits, the maximum value of the candidate X1 is X3, and X3 is a positive integer.

[0697] As an example, the maximum value of the candidate X3 is fixed.

[0698] As an example, the maximum value of the candidate X3 is variable.

[0699] As an example, the candidate maximum value of X3 is predefined. This scheme is simple to implement.

[0700] As an example, the maximum value of the candidate X3 depends on the reception parameters of the first broadcast channel.

[0701] As an example, the maximum value of the candidate X3 is 4.

[0702] As an example, the maximum value of the candidate X3 is 5.

[0703] As an example, the minimum candidate value of X1 is X4, where X4 is a positive integer and is less than X3. This method ensures that the change cycle of MIB messages is not too short.

[0704] As an example, the maximum value of the candidate X3 is 4, and the minimum value of the candidate X3 is 2.

[0705] As an example, the maximum value of the candidate X3 is 3, and the minimum value of the candidate X3 is 2.

[0715] As a sub-example, the first candidate type includes a slice, and the second candidate type includes another slice, which are different from each other, and both slices support 6G.

[0716] As a sub-implementation, in response to the receipt of the first broadcast information, whether the first node performs cell reselection depends on whether the first node supports the type of the first cell; if the first node does not support the type of the first cell, the first node performs cell reselection; if the first node supports the type of the first cell, the first node obtains the SIB1 message of the first cell.

[0717] As an example, when X1 is less than X3, a field in the MIB message included in the first broadcast information depends on at least one bit in the first bit group included in the first broadcast information. This scheme is beneficial for the reception of SIB1.

[0718] As a sub-example, the interpretation of a field in the MIB message included in the first broadcast information depends on at least one bit in the first bit group included in the first broadcast information.

[0719] As a sub-example, the value of the field in the MIB message included in the first broadcast information depends on at least one bit in the first bit group included in the first broadcast information.

[0720] As a sub-example, the field in the MIB message included in the first broadcast information indicates the WUS configuration for the SIB1 message.

[0723] As an example, when X1 is less than X3, at least one bit in the first bit group included in the first broadcast information is reserved. This scheme is beneficial for protocol extension.

[0724] As an example, at least one bit in the first bit group included in the first broadcast information is a portion of the bits other than the X1 bits in the first bit group included in the first broadcast information.

[0725] As an example, the at least one bit in the first bit group included in the first broadcast information is all bits other than the X1 bits in the first bit group included in the first broadcast information.

[0726] As an example, the at least one bit in the first bit group included in the first broadcast information is one bit other than the X1 bits in the first bit group included in the first broadcast information.

[0727] As an example, the at least one bit in the first bit group included in the first broadcast information is two bits other than the X1 bits in the first bit group included in the first broadcast information.

[0728] As an example, the X3 bits are consecutive, and the X1 bits of the least significant bit of the SFN are consecutive.

[0729] As an example, this example does not limit the positions of the X1 bits and the (X3-X1) bits in the first bit group.

[0730] Typically, the first bit group included in the first broadcast information is X3 bits; the first bit group included in the first broadcast information is not in the MIB message encoding.
