Description

Technical Field

[0001] This application relates to transmission methods and apparatus in wireless communication systems, and more particularly to schemes and apparatus for TCI (Transmission Configuration Indicator) in wireless communication systems. Background Technology

[0002] Multi-antenna technology is a key technology in 3GPP (3rd Generation Partner Project) LTE (Long-Term Evolution) and NR (New Radio) systems. It gains additional spatial degrees of freedom by configuring multiple antennas at communication nodes, such as base stations or UEs (User Equipment). Multiple antennas improve communication quality by beamforming, forming beams pointing in a specific direction. When multiple antennas belong to different TRPs (Transmitter Receiver Points) / panels, additional diversity gain can be obtained by utilizing the spatial differences between different TRPs / panels. Since the beams formed by multiple antennas are relatively narrow, the communicating parties need to align the beams to provide communication quality. Starting with NRR (Release) 15, 3GPP introduced the concept of TCI (Transmission Configuration Indication) to assist in beam alignment between transmission nodes. In R17, the unified TCI architecture was introduced to unify uplink and downlink beam processing, improving performance and reducing latency.

[0003] With the adoption of new technologies, the increase in the number of antennas, the diversification of application scenarios, and the increasing demands on system performance, traditional measurement and reporting methods incur significant redundant overhead. Therefore, in NR R (release) 18, research on AI (Artificial Intelligence) / ML (Machine Learning) technologies was initiated to explore their impact on system performance and system design. Compared to traditional processing methods, AI / ML offers advantages such as training-based operation and deployment requirements. Summary of the Invention

[0004] The applicant discovered through research that existing TCI-based beam management schemes need to be enhanced when AI / ML functions are introduced. To address this issue, this application discloses a solution. It should be noted that while many embodiments of this application are focused on AI / ML, this application is also applicable to other schemes, such as traditional TCI-based beam management schemes. Furthermore, using a unified solution across different scenarios (including but not limited to AI / ML-based schemes and traditional TCI-based beam management schemes) helps reduce hardware complexity and cost. 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.

[0309] Example 3 illustrates a schematic diagram of an embodiment of a wireless protocol architecture for a user plane and a control plane according to this application, as shown in the attached diagram. Figure 3 As shown. Figure 3 This is a schematic diagram illustrating an embodiment of a radio protocol architecture for the user plane 350 and the control plane 300. Figure 3The radio protocol architecture of the control plane 300 between the first communication node device (UE, gNB, or RSU in V2X) and the second communication node device (gNB, UE, or RSU in V2X), or between two UEs, is illustrated using 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. Layer 1 will be referred to as PHY 301 in this document. Layer 2 (L2 layer) 305, above PHY 301, is responsible for the link between the first and second communication node devices, or between two UEs. Layer 2 305 includes the MAC (Medium Access Control) sublayer 302, the RLC (Radio Link Control) sublayer 303, and the PDCP (Packet Data Convergence Protocol) sublayer 304, which terminate at the second communication node device.

[0319] Example 4

[0320] Example 4 illustrates a schematic diagram of a first communication device and a second communication device according to an embodiment of this application, as shown in the attached diagram. Figure 4 As shown. (Attached) Figure 4 This is a block diagram of a first communication device 410 and a second communication device 450 communicating with each other in an access network.

[0321] The first 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.

[0322] The second 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.

[0323] In the transmission from the first communication device 410 to the second communication device 450, at the first 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 DL (Downlink), the controller / processor 475 provides header compression, encryption, packet segmentation and reordering, multiplexing between logical and transport channels, and radio resource allocation to the second communication device 450 based on various priority metrics. The controller / processor 475 is also responsible for HARQ operation, retransmission of lost packets, and signaling to the second communication device 450. The transmit processor 416 and the multi-antenna transmit processor 471 implement various signal processing functions for L1 layer (i.e., physical layer). Transmit processor 416 performs encoding and interleaving to facilitate forward error correction (FEC) at the second communication device 450, and constellation mapping based on various modulation schemes (e.g., binary phase shift keying (BPSK), quadrature phase shift keying (QPSK), M-phase shift keying (M-PSK), and M-quadrature amplitude modulation (M-QAM). Multi-antenna transmit processor 471 performs digital spatial precoding on the encoded and modulated symbols, including codebook-based precoding and non-codebook-based precoding, and beamforming processing, generating one or more parallel... The transmit processor 416 then maps each parallel stream to a subcarrier, multiplexes the modulated symbols with a reference signal (e.g., a pilot) in the time and / or frequency domains, and then uses an inverse fast Fourier transform (IFFT) to generate a physical channel carrying the time-domain multicarrier symbol stream. The 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 transmit processor 471 into an RF stream, which is then provided to a different antenna 420.

[0324] In the transmission from the first communication device 410 to the second communication device 450, at the second 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 parallel stream destined for the second communication device 450. Symbols on each parallel 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 over the physical channel by the first communication device 410. 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 (L2). 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 DL (Layered Logic), the controller / processor 459 provides multiplexing, packet reassembly, decryption, header decompression, and control signal processing between the transmission and logical channels to recover upper-layer packets from the core network. The upper-layer packets are then provided to all protocol layers above Layer 2. Various control signals may also be provided to Layer 3 (L3) for L3 processing. The controller / processor 459 is also responsible for error detection using ACK and / or NACK protocols to support HARQ operation.

[0325] In the transmission from the second communication device 450 to the first communication device 410, at the second 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 first communication device 410 described in the DL, the controller / processor 459 implements header compression, encryption, packet segmentation and reordering, and multiplexing between logical and transport channels based on the radio resource allocation of the first communication device 410, implementing L2 layer functions for the user plane and control plane. The controller / processor 459 is also responsible for HARQ operations, retransmission of lost packets, and signaling to the first 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 parallel 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.

[0326] In the transmission from the second communication device 450 to the first communication device 410, the function at the first communication device 410 is similar to the receiving function at the second communication device 450 described in the transmission from the first communication device 410 to the second 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. The controller / processor 475 provides multiplexing, packet reassembly, decryption, header decompression, and control signal processing between the transmission and logical channels to recover upper-layer data packets from the second communication device 450. The upper-layer data packets from the controller / processor 475 may be provided to the core network. The controller / processor 475 is also responsible for error detection using ACK and / or NACK protocols to support HARQ operation.

[0386] Example 7

[0387] Example 7 illustrates a schematic diagram of the relationship between S1 time intervals and S1 code points according to an embodiment of this application; as shown in the attached diagram. Figure 7 As shown. In the appendix Figure 7 In the diagram, time interval #1, ..., target time interval, ..., time interval #S1 represents S1 time intervals; code point #1, ..., first code point, ..., code point #S1 represents S1 code points.

[0388] In embodiment 7, the first MAC CE indicates S1 time intervals for each of the S1 code points of the target field, where S1 is a positive integer greater than 1 and not greater than S; the target time interval is one of the S1 time intervals, the value of the target field in the first DCI is a first code point, the first code point is one of the S1 code points, and the target time interval is indicated to the first code point.

[0389] As an example, the S1 code points of the target domain are mapped to S1 TCI state groups, each of the S1 TCI state groups includes two TCI states, and the S1 TCI state groups belong to the S TCI state groups.

[0390] As an example, S1 code points out of the S code points of the target domain are respectively mapped to multiple TCI states, and any code point other than the S1 code points out of the S code points of the target domain is mapped to only one TCI state; the first MAC CE indicates S1 time intervals for the S1 code points of the target domain, where S1 is a positive integer greater than 1 and not greater than S, and the target time interval is one of the S1 time intervals.

[0391] As an example, in the above method, the time interval is indicated according to each code point of the target domain, which improves flexibility.

[0392] As an example, in the above method, the TCI states mapped to different code points in the target domain are applied at different times, which provides greater flexibility.

[0393] As an example, any two of the S1 time intervals are different.

[0394] As an example, two of the S1 time intervals are the same.

[0395] As an example, among the S code points of the target domain, there is one code point that is mapped to only one TCI state. The RS resources in the TCI state to which the code point is mapped and the first type of signal in the first time window are quasi-co-located. Furthermore, the RS resources in the TCI state to which the code point is mapped and the first type of signal in the second time window are quasi-co-located.

[0396] As an example, S1 is equal to S.

[0397] As an example, the first MAC CE indicates S time intervals for each of the S code points of the target field; the target time interval is one of the S time intervals, the value of the target field in the first DCI is a first code point, the first code point is one of the S code points, and the target time interval is indicated to the first code point.

[0398] Typically, the S code points of the target domain include the S1 code points of the target domain.

[0399] As an example, the first MAC CE includes a first set of fields, which consists of S1 fields; the S1 fields of the first MAC CE are S1 code points indicating S1 time intervals for the target field.

[0400] As an example, the above method uses the S1 fields of the first MAC CE to indicate the S1 time intervals respectively, which provides high flexibility.

[0401] As an example, the S1 fields of the first MAC CE correspond to the S1 code points of the target field.

[0402] As an example, the S1 fields of the first MAC CE are sequentially mapped to the S1 code points of the target field.

[0403] As an example, any one of the S1 fields corresponds to one of the S1 code points according to its ordinal position in the S1 fields.

[0404] As an example, any one of the S1 fields is mapped to one of the S1 code points according to its ordinal position in the S1 fields.

[0405] As an example, the S1 fields are sequentially mapped to the S1 code points of the target field, and the S1 TCI state groups are sequentially mapped to the S1 code points. The i-th field in the S1 fields corresponds to the i-th TCI state group in the S1 TCI state groups, where i is a positive integer not greater than S1.

[0406] As an example, the S1 fields of the first MAC CE respectively indicating S1 code points and S1 time intervals of the target field include: the values ​​of the S1 fields of the first MAC CE are respectively equal to the S1 time intervals.

[0407] As an example, the S1 fields of the first MAC CE respectively indicating S1 code points of the target domain for S1 time intervals include: the time interval corresponding to a code point of the target domain in one of the S1 fields of the first MAC CE is equal to the value of the one field.

[0408] As an example, the S1 fields of the first MAC CE, which indicate S1 time intervals for S1 code points of the target field, include: the i-th field indicates a time interval for the i-th code point of the target field, and the i-th field belongs to the S1 fields of the first MAC CE; i is a positive integer not greater than S1.

[0409] As an example, the i-th field of the first MAC CE indicates a time interval for the i-th code point of the target field; i is a positive integer not greater than S1.

[0410] As an example, the S1 fields of the first MAC CE respectively indicating S1 code points and S1 time intervals of the target field include: each of the S1 fields of the first MAC CE includes one bit; when one of the S1 fields is set to 1, the time interval indicating the code point of the corresponding field of the target field is a second value; when one of the S1 fields is set to 0, the time interval indicating the code point of the corresponding field of the target field is a third value.

[0411] As an example, the above method divides the S1 code points of the target domain into two code point groups, each indicating a different time interval, thus ensuring flexibility while reducing signaling overhead.

[0412] As an example, the second value is the default.

[0413] As an example, the second value is fixed.

[0414] As an example, the second value is configurable.

[0415] As an example, the second value is configured by RRC signaling.

[0426] As an example, the unit of the third value is a time slot.

[0427] As an example, the third value includes a positive integer number of time slots.

[0428] Example 8

[0429] Example 8 illustrates a schematic diagram of the relationship between M1 time intervals and M1 TCI states according to an embodiment of this application; as attached. Figure 8 As shown. In the appendix Figure 8 In the table, time interval #1, ..., target time interval, ..., time interval #M1 represents M1 time intervals; TCI state #1, ..., TCI state #n, ..., TCI state #M1 represents M1 TCI states.

[0430] In embodiment 8, the value of the target field in the first DCI is a first code point, which is one of the S1 code points. The first MAC CE indicates a target time interval group for the first code point. The target time interval group includes M1 time intervals, and the target time interval is one of the M1 time intervals. M1 is a positive integer greater than 1.

[0431] As an example, Appendix Figure 8 In (a), the M1 time intervals are indicated to each TCI state in the first TCI state group.

[0432] As an example, Appendix Figure 8In (b), the M1 time intervals are respectively indicated to the M1 TCI states in the first TCI state group.

[0433] As an example, in the above method, the time interval of each TCI state in the first TCI state group is indicated separately, which provides high flexibility.

[0434] As an example, the first MAC CE includes first information, which indicates that the first code point corresponds to one or more time intervals.

[0435] As an example, the first MAC CE includes first information, which indicates the number of time intervals corresponding to the first code point.

[0436] As an example, one code point corresponding to one time interval means that the one time interval is indicated to the one code point.

[0437] As an example, one code point corresponding to one time interval means that the one time interval is mapped to the one code point.

[0438] As an example, the first MAC CE includes first information, which indicates that the first code point corresponds to one or more time intervals.

[0439] As a sub-implementation of the above embodiment, when the first information is set to 0, the first information indicates that the first code point corresponds to a time interval; when the first information is set to 1, the first information indicates that the first code point corresponds to multiple time intervals.
