Description

Technical Field

[0001] This application relates to signal transmission methods and apparatus in wireless communication systems, and more particularly to uplink synchronization methods and apparatus. 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 freedom by configuring multiple antennas at communication nodes, such as base stations or UEs (User Equipment). Multiple antennas, through beamforming, form beams pointing in a specific direction to improve communication quality. When multiple antennas belong to multiple TRPs (Transmitter Receiver Points) / panels, additional diversity gain can be obtained by utilizing the spatial differences between different TRPs / panels. Among these, deploying a heterogeneous network, enabling the UE to receive downlink (DL) transmissions from a gNB but send uplink (UL) transmissions to the gNB or non-co-located TRPs / panels, is an important enhancement scheme to improve uplink throughput. Furthermore, TRPs / panels receiving UL transmissions can reduce or even disable DL transmissions to reduce energy consumption.

[0003] In December 2023, the RAN (Radio Access Network) plenary session #102 approved the WI (Work Item) for NRMIMO Phase 5. The RAN1 working group, in Rel-19, at least enhanced UL power control (PC) to support this UL / DL asymmetric deployment scenario. This includes configuring path loss offset for UE to facilitate accurate calculation of path loss associated with UE and TRP / panel; and supporting two closed-loop PC conditioning states for DLCSI (Channel State Information) acquisition for gNB and SRS (Sounding Resource Signal) transmission for UL multi-TRP. Summary of the Invention

[0004] In existing standards, to avoid transmission interference and ensure that uplink signals sent by all UEs served by the base station are aligned upon arrival at the base station, the base station sends a Timing Advance (TA) adjustment instruction to the UE via Medium Access Control (MEC) layer signaling. The UE determines the downlink timing based on the downlink signal from the base station and, combined with the TA adjustment instruction sent by the base station, can accurately determine the actual uplink transmission timing. Cells with the same timing advance and using the same timing reference are grouped into a Timing Advance Group (TA), and each TAG includes at least one serving cell configured with uplink. In UL / DLasymmetric scenarios, UE uplink transmissions may correspond to different beams / TRPs / panels, and different beams / TRPs / panels may correspond to different TAs. How to support different TAs within a single TAG and how to determine the transmission timing targeted by the TA adjustment indicated by MAC signaling are problems that need to be solved.

[0005] To address the aforementioned issues, this application discloses a solution. It should be noted that while the NR (New Radio) system is used as an example in the problem description above, this application is also applicable to scenarios such as future 6G systems, achieving similar technical effects. Furthermore, although the initial intention of this application is for UL / D Lasymmetric, cellular networks, uplink transmission, and multi-beam / TRP / panel scenarios, this application can also be applied to other non-UL / D Lasymmetric scenarios. Furthermore, it is applicable to different scenarios (such as other non-UL / DL asymmetric scenarios, including but not limited to sidelink transmission, downlink transmission, single-beam / TRP / panel, RIS (Reconfigurable Intelligent Surface), Vehicle to Everything (V2X), NCR (Network Control Repeater) capacity enhancement systems, short-range communication systems, NTN (Non-Terrestrial Network), IoT (Internet of Things), and URLLC (Ultra Reliable Low Latency)). Adopting a unified design scheme for communication networks (such as ultra-robust low-latency communication networks) also helps reduce hardware complexity and cost.

[0015] This application discloses a method used in a first node for uplink synchronization in wireless communication, comprising:

[0016] Receive the first signaling, which indicates the first timing advance value;

[0017] Send the first signal in the first time-frequency resource;

[0018] Wherein, the first signaling indicates a target identifier; whether the first time-frequency resource includes the first timing advance value depends on whether the spatial parameters used by the first signal are consistent with the target identifier; when the target identifier is a first identifier and the spatial parameters used by the first signal are a first indicated TCI state, or the target identifier is a second identifier and the spatial parameters used by the first signal are a second indicated TCI state, the first time-frequency resource includes the first timing advance value; when the target identifier is a first identifier and the spatial parameters used by the first signal are a second indicated TCI state, or the target identifier is a second identifier and the spatial parameters used by the first signal are a first indicated TCI state, the first time-frequency resource does not include the first timing advance value.

[0019] As an example, the problem this application aims to solve includes: how to support different TAs in a serving cell.

[0020] As an example, the problem to be solved by this application includes: the uplink timing of the first node.

[0021] As an example, the problem to be solved by this application includes: determining the TA adjustment value in an uplink-downlink asymmetric deployment scenario.

[0022] As an example, the features of the above method include: in this application, the spatial parameters of the uplink signal that the determination of the TA in the uplink timing of the first node depends on are consistent with the target identifier, thereby solving the above problem.

[0023] As an example, the features of the above method include: in UL / DL asymmetric scenarios, downlink transmission is based on a single TRP, and the base station will not configure two TAGs at the same time. Therefore, the field in the MAC CE that originally indicates the TAG can be used to indicate the uplink TRP corresponding to the TA indicated or updated in the MAC.

[0024] As an example, the features of the above method include: redefining the indication and interpretation of TA while keeping the existing TAC structure unchanged, in order to support uplink and downlink asymmetric scenarios.

[0025] As an example, the features of the above method include: the target signaling is used to indicate or update a terminal-specific timing advance.

[0026] As an example, the features of the above method include: the target identifier explicitly indicates the uplink TRP corresponding to the TA in the TAC.

[0027] As an example, the features of the above method include: when the spatial parameters used by the first signal are consistent with the target identifier, the uplink TRP targeted by the timing advance indicated or updated by the first signaling is consistent with the uplink TRP for receiving the first signal. Therefore, the timing advance indicated by the first signaling is used for uplink timing when transmitting the first signal.

[0028] As an example, the features of the above method include: when the spatial parameters used by the first signal are inconsistent with the target identifier, the uplink TRP targeted by the timing advance indicated or updated by the first signaling is inconsistent with the uplink TRP for receiving the first signal. Therefore, the timing advance indicated by the first signaling is not used for uplink timing when transmitting the first signal.

[0029] As an example, the advantages of the above method include: supporting uplink multi-beam / TRP / panel transmission based on different timing advance values, thereby improving uplink transmission performance.

[0030] As an example, the advantages of the above method include: supporting uplink asymmetric deployment scenarios and improving uplink throughput.

[0033] As an example, the advantages of the above method include: solving the problem of supporting different TAs within a single TAG, requiring minimal changes to the current standard, and being easy to implement.

[0034] According to one aspect of this application, the above method is characterized in that the target identifier is a TAG ID or the target identifier is a TI, and the cell to which the first timing advance value is targeted is not configured with two TAGs.

[0035] As an example, the features of the above method include: in uplink and downlink asymmetric scenarios, the mobile phone sends uplink to the base station or to a remote TRP dedicated to receiving uplink, which corresponds to the same TAG.

[0036] As an example, the features of the above method include: in a scenario where two TAGs are configured simultaneously, the target identifier indicates the TAG to which the TA in the first signaling is targeted; however, in an uplink-downlink asymmetric deployment scenario, the cell to which the first timing advance value is targeted is not configured with two TAGs, and the target identifier is not set as a reserved value, but is reinterpreted as an identifier that supports different TAs under one TAG.

[0037] As an example, the advantages of the above method include: reducing standard modifications and facilitating implementation.

[0038] As an example, the benefits of the above method include: reducing interference and enhancing system robustness.

[0047] According to one aspect of this application, the above method is characterized in that the cell to which the first timing advance value is targeted is not configured with two coresetPoolIndex.

[0048] As an example, the features of the above method include: existing base stations that support uplink and downlink asymmetric scenarios do not apply multiple downlink TRPs at the same time, so there is no need to configure two CORESET Pools for downlink TRPs.

[0049] As an example, the characteristics of the above method include: the first node cannot be configured with both two uplink SRS resource sets and two coresetPoolIndex.

[0050] As an example, the advantages of the above method include: supporting different TRP deployment schemes under different deployment environments and network loads, reducing costs, simplifying deployment management, and simplifying system implementation.

[0054] As an example, the features of the above method include: in UL / DL asymmetric scenarios, in order to facilitate accurate calculation of the path loss associated with the terminal and the TRP / panel, the base station can configure a path loss offset for the UL TRP for the terminal. Therefore, the terminal can determine the TRP / panel corresponding to the uplink transmission by whether the uplink RS resource is configured with a path loss offset, and thus determine the uplink timing in different scenarios.

[0055] As an example, the features of the above method include: at least one of the at least two uplink RS resource sets is included, the uplink RS resource set is configured to reference downlink reference signal resources, and the uplink resources are configured with path loss offset.

[0056] As an example, the features of the above method include: the two uplink RS resource sets are respectively associated with two indicated TCI states, one of the two indicated TCI states is configured with a reference downlink reference signal resource and is configured with a path loss offset.

[0057] As an example, the advantages of the above method include: the terminal determines the receiver of the uplink RS resource based on whether a path loss offset is configured, thus saving signaling overhead.

[0058] As an example, the advantages of the above method include: supporting uplink asymmetric deployment scenarios and improving uplink throughput.

[0059] According to one aspect of this application, the above method is characterized in that, when the first signal and the uplink RS resource are QCL, the transmit power value of the first signal depends simultaneously on the downlink reference signal resource and the path loss offset.

[0060] As an example, the features of the above method include: when the first signal and the RS resource are QCL, the receiver of the first signal is UL TRP.

[0061] As an example, the features of the above method include: the downlink reference signal resource includes a downlink reference signal; the first node can obtain the downlink path loss between the base station and the first node by measuring the downlink reference signal; when the first signal and the uplink RS resource are QCL, the receiver of the first signal is UL TRP; and the first node determines the uplink transmission path loss based on the downlink path loss between the base station and the first node and the path loss offset.

[0062] As an example, the advantages of the above method include: correcting the uplink transmission path loss of the terminal's transmitted signal, thereby more accurately estimating the transmission link quality from the terminal to the UL TRP.

[0063] As an example, the benefits of the above method include: ensuring more accurate resource allocation and scheduling in the network, and improving network performance and throughput.

[0064] As an example, the advantages of the above method include: enhanced uplink power control, ensuring the transmission quality of uplink signals, and saving power resources.

[0065] According to one aspect of this application, the above method is characterized in that the uplink RS resource corresponding to the first indicated TCI state belongs to the first uplink RS resource set, and the uplink RS resource corresponding to the second indicated TCI state belongs to the second uplink RS resource set; at least one uplink RS resource in the first uplink RS resource set and one uplink RS resource in the second uplink RS resource set are configured with the same reference downlink reference signal resource.

[0066] As an example, the features of the above method include: a first uplink RS resource belongs to a first uplink RS resource set, a second uplink RS resource belongs to a second uplink RS resource set, the first node measures a first downlink reference signal to obtain a first path loss, the transmit power value of the first uplink RS resource depends on the first path loss, and the transmit power value of the second uplink resource depends on the first path loss and a configured path loss offset.

[0336] Example 3

[0337] Example 3 illustrates a schematic diagram of an embodiment of a wireless protocol architecture for the user plane and control plane according to an embodiment of this application, as shown in the attached diagram. Figure 3 As shown.

[0338] Figure 3 This is a schematic diagram illustrating an embodiment of a wireless protocol architecture for the user plane 350 and the control plane 300. Figure 3The wireless protocol architecture for the control plane 300 between the first communication node device (UE or RSU in V2X, onboard equipment or onboard communication module) and the second node device (gNB, UE or RSU in V2X, onboard equipment or onboard communication module), or between two UEs, is illustrated using three layers: Layer 1 (L1), Layer 2 (L2), and Layer 3 (L3). L1 is the lowest layer and implements various PHY (Physical layer) signal processing functions. L1 will be referred to as PHY 301 in this document. L2 305 sits above PHY 301 and is responsible for the link between the first and second node devices, or between two UEs, via PHY 301. L2305 includes a MAC (Medium Access Control) sublayer 302, an RLC (Radio Link Control) sublayer 303, and a PDCP (Packet Data Convergence Protocol) sublayer 304, which terminate at the second node device. The PDCP sublayer 304 provides multiplexing between different radio bearers and logical channels. It also provides security through encrypted data packets and supports cross-cell mobility between the second communication node devices and the first communication node device. The RLC sublayer 303 provides upper-layer packet segmentation and reassembly, retransmission of lost packets, and packet reordering to compensate for out-of-order reception due to HARQ (Hybrid Automatic Repeat reQuest).

[0348] Example 4

[0349] 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.

[0350] 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.

[0351] 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.

[0352] 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 functionality. In the DL, 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 (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-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 streams. 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.

[0353] 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 L1 signal processing functions. 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 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 L2 functionality. 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, 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 L2. Various control signals may also be provided to L3 for L3 processing. The controller / processor 459 is also responsible for error detection using ACK and / or NACK protocols to support HARQ operation.

[0354] 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 L2. 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 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.

[0355] 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 function. The controller / processor 475 implements the L2 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. 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.
