Technical Field

[0002] This application relates to transmission methods and apparatus in wireless communication systems, and in particular to methods and apparatus for transmitting wireless signals in wireless communication systems that support non-terrestrial networks or cellular networks. Background Technology

[0003] In discussions for NRR Release 17, 3GPP (3rd Generation Partner Project) has agreed to support the ability to enable / disable HARQ-ACK (Hybrid Automatic Repeat reQuestACK knowledgement) feedback for each HARQ process in non-terrestrial networks (NTN).

[0004] The 105th meeting of 3GPP RAN1 has agreed that for Type-2 HARQ-ACK codebooks, the DAI (Downlink Assignment Index) field in the DCI used to schedule HARQ processes with HARQ-ACK feedback enabled will only count for HARQ processes with HARQ-ACK feedback enabled. Summary of the Invention

[0005] Against this backdrop, it is a reasonable and effective alternative to count only the HARQ processes enabled by HARQ-ACK feedback in the DCI used to schedule HARQ-ACK feedback enablement. This alternative can enhance the consistency of HARQ-ACK feedback understanding between the communicating parties and improve transmission efficiency, thus showing good prospects for standardization. If the above alternative is adopted, since the transmission power of the PUCCH in the second type of HARQ-ACK codebook is related to the DAI value, how to use the new DAI field interpretation method to achieve more accurate power control is an important issue worthy of research.

[0006] To address the aforementioned issues, this application discloses a solution. It should be noted that although the above description uses HARQ-ACK feedback in NTN as an example, this application is equally applicable to other scenarios, such as MBS (Multicast and Broadcast Services), URLLC (Ultra-Reliable and Low-Latency Communication), sidelinks, and scenarios where physical layer signaling is used to dynamically indicate HARQ-ACK feedback enabling / disabling, achieving similar technical effects. Furthermore, adopting a unified solution across different scenarios (including but not limited to NTN, MBS, URLLC, sidelinks, and scenarios where physical layer signaling is used to dynamically indicate HARQ-ACK feedback enabling / disabling) can help reduce hardware complexity and cost, or improve performance. Unless otherwise specified, embodiments and features in any node of this application can be applied to any other node. Unless otherwise specified, embodiments and features in any embodiment of this application can be arbitrarily combined with each other.

[0007] As an example, the interpretation of the terminology in this application is based on the definitions in the 3GPP specification protocol TS36 series.

[0008] As an example, the interpretation of terms in this application is based on the definitions in the 3GPP specification protocol TS38 series.

[0009] As an example, the interpretation of the terms in this application is based on the definitions in the 3GPP specification protocol TS37 series.

[0010] As an example, the interpretation of terms in this application is based on the definitions in the IEEE (Institute of Electrical and Electronics Engineers) specification protocols.

[0011] This application discloses a method used in a first node of wireless communication, characterized by comprising: Receive a first information block and a first signaling set, wherein the first signaling set includes multiple control signaling, and the first control signaling is a control signaling included in the first signaling set; A first PUCCH is transmitted at a first transmit power, the first PUCCH carrying at least one HARQ-ACK bit; Wherein, the first reference HARQ-ACK bit count is used to determine the first transmit power, and the first reference HARQ-ACK bit count is a positive integer; the first control signaling includes a first field, and the value of the first field included in the first control signaling is a positive integer; a first intermediate quantity is used to determine the first reference HARQ-ACK bit count, and the first intermediate quantity is linearly related to the value of the first field included in the first control signaling; the first signaling set includes a target signaling subset, and the target signaling subset includes at least one control signaling, and the first intermediate quantity is linearly related to the number of control signalings included in the target signaling subset; the first information block is used to determine whether the first control signaling belongs to the target signaling subset.

[0012] As an example, the problem to be solved by this application includes: how to reasonably and effectively use the value of the DAI field in the DCI format of the HARQ process used to schedule HARQ-ACK feedback to enable PUCCH power control.

[0013] As an example, the problem this application aims to solve includes: how to achieve precise PUCCH power control after the HARQ-ACK feedback enable and disable functions are configured.

[0014] As an example, the features of the above method include: the first control signaling can be a DCI format used to schedule HARQ processes that are enabled by HARQ-ACK feedback or a DCI format used to schedule HARQ processes that are disabled by HARQ-ACK feedback, and the target signaling subset does not include any DCI format used to schedule HARQ processes that are disabled by HARQ-ACK feedback.

[0015] As an example, the features of the above method include: in the conventional scheme of PUCCH power control, the target signaling subset is the first signaling set, therefore, the DCI format to which the DAI field used to determine the number of the first reference HARQ-ACK bits belongs is always one of the target signaling subsets; in contrast to the conventional scheme of PUCCH power control, in the method disclosed in this application: under specific conditions (e.g., the first control signaling indicates a HARQ process that is enabled by the first information block for HARQ-ACK feedback), the DCI format to which the DAI field used to determine the number of the first reference HARQ-ACK bits belongs (i.e., the first control signaling) does not belong to the target signaling subset.

[0016] As an example, the features of the above method include: the HARQ process that indicates HARQ-ACK feedback to be disabled in the first signaling set and is not the last (or not detected in the last PDCCH monitoring time) DCI format is not used to determine the first transmit power.

[0017] As an example, the features of the above method include: determining whether the first control signaling is counted in the number of control signalings included in the target signaling subset based on the configuration or indication of the first information block, according to whether the first control signaling instructs HARQ-ACK feedback to be enabled.

[0018] As an example, the benefits of the above method include: enhancing the consistency of understanding between the communicating parties regarding the number of HARQ-ACK bits being fed back.

[0019] As an example, the advantages of the above method include: more accurate PUCCH power control is achieved by effectively utilizing the new interpretation method of the DAI domain.

The PDCP sublayer 304 provides multiplexing between different radio bearers and logical channels. PDCP sublayer 304 also provides security through encrypted data packets and supports cross-cell mobility between second communication node devices and the first communication node device. RLC sublayer 303 provides upper layer data packet segmentation and reassembly, retransmission of lost data packets, and data packet reordering to compensate for out-of-order reception due to HARQ. 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 between the first communication node devices. MAC sublayer 302 is also responsible for HARQ operations. The 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 configuring the lower layer using RRC signaling between the second and first communication node devices. The radio protocol architecture of user plane 350 includes layer 1 (L1 layer) and layer 2 (L2 layer). The radio protocol architecture for the first and second communication node devices in user plane 350 is largely the same as the corresponding layers and sublayers in control plane 300 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. However, PDCP sublayer 354 also provides header compression for upper layer data packets to reduce radio transmission overhead.The L2 layer 355 in the user plane 350 also includes an SDAP (Service Data Adaptation Protocol) sublayer 356, which is responsible for mapping between QoS flows and data radio bearers (DRBs) to support service diversity. Although not illustrated, the first communication node device may have several upper layers above the L2 layer 355, including a network layer (e.g., IP layer) terminating at the P-GW on the network side and an application layer terminating at the other end of the connection (e.g., a remote UE, server, etc.).

[0316] Example 4 Example 4 shows schematic diagrams of a first communication device and a second communication device according to this application, as shown in the appendix. Figure 4 As shown. 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.

[0317] 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.

[0318] 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.

[0319] 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 the transmission from the first communication device 410 to the second 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 second communication device 450 based on various priority metrics. The controller / processor 475 is also responsible for retransmitting 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 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 450, 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.

[0320] 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 spatial stream destined for the second 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 first 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 first communication device 410 to the second 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.

[0321] 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 transmission from the first communication device 410 to the second 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 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 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.

[0322] 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 function. The controller / processor 475 implements the L2 layer function. The controller / processor 475 may be associated with a memory 476 storing program code and data. The memory 476 may be referred to as computer-readable media. In the transmission from the second communication device 450 to the first 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 data packets from the controller / processor 475 can be provided to the core network.
