Description

Technical Field

[0001] This application relates to transmission methods and apparatus in wireless communication systems, and more particularly to transmission schemes and apparatus for semi-static scheduling or configuration scheduling in wireless communication. Background Technology

[0002] In 5G NR (New Radio), Massive MIMO (Multi-Input Multi-Output) is a key technology. In Massive MIMO, multiple antennas use beamforming to form a narrow beam pointing in a specific direction to improve communication quality. In 5G NR, base stations can update the TCI (Transmission Configuration Indication) for receiving the PDCCH (Physical Downlink Control Channel) and the TCI for receiving the PDSCH (Physical Downlink Shared Channel) using MAC (Medium Access Control) CE (Control Elements) or dynamic signaling, thereby ensuring the performance gains from beamforming. Similarly, base stations can also update the QCL (Quasi Co-located) parameters used by multiple different types of physical layer channels or the QCL parameters on multiple carriers using a DCI (Downlink Control Information) to reduce signaling overhead.

[0003] In the NR R17 discussion, inter-cell operation issues related to the Multi-TRP (Transmitter-Receiver Node) scenario are being discussed. Among them, in the RAN1#104b-e meeting, an additional PCI (Physical Cell Identity) different from the Serving Cell PCI was introduced. Summary of the Invention

[0004] In existing NR systems, when a base station schedules a terminal using a PDCCH identified by a specific RNTI (Radio Network Temporary Identifier), the corresponding data channel indicated by the PDCCH is also scrambled using that specific RNTI to resist interference. Simultaneously, the base station activates or deactivates / releases downlink SPS (Semi-Persistent Scheduling) or uplink Type 2 CS (Configured Scheduling) using a PDCCH identified by an RNTI other than C-RNTI (Cell Radio Network Temporary Identifier). However, in the M-TRP scenario, the base station can dynamically update the QCL relationship of the PDSCH received by the UE or the PUSCH (Physical Uplink Shared Channel) sent by the UE through DCI. Furthermore, the updated QCL relationship may switch from being associated with the serving cell PCI to being associated with a non-serving cell PCI. Therefore, when an SPS configuration or a CS configuration spans two TCI states that are associated with different PCIs, how to handle the above SPS configuration or CS configuration needs to be reconsidered.

[0005] To address the non-dynamic scheduling problem in the aforementioned M-TRP scenario, this application discloses a solution. It should be noted that the description in this application uses M-TRP as only a typical application scenario or example; this application is also applicable to other scenarios facing similar problems, such as single-TRP scenarios, scenarios involving joint cooperation between multiple base stations, scenarios with more capable base stations or user equipment, or for different technical fields, such as dynamic scheduling, channel estimation, measurement, demodulation, etc., in addition to SPS or CS, to achieve similar technical effects. Furthermore, adopting a unified solution for different scenarios (including but not limited to M-TRP scenarios) helps reduce hardware complexity and cost. Where there is no conflict, the embodiments and features in the first node device of this application can be applied to the second node device, and vice versa. In particular, the explanations of terms, nouns, functions, and variables in this application (unless otherwise specified) can refer to the definitions in the 3GPP Technical Specification (TS) series 36, TS38, and TS37.

[0006] This application discloses a method for a first node in wireless communication, comprising:

[0007] Receive a first signaling message, which is used to determine a first time-frequency resource;

[0008] Receive the first signal in the first time-frequency resource;

[0009] Wherein, the first signaling is identified by a target RNTI; whether the target RNTI is used for scrambling the first signal is related to the type of the target RNTI; the type of the target RNTI belongs to one of a first type set and a second type set; when the type of the target RNTI belongs to the first type set, the target RNTI is used for scrambling the first signal, and when the type of the target RNTI belongs to the second type set, the target RNTI is not used for scrambling the first signal; only the first type set includes C-RNTI; no RNTI type belongs to both the first type set and the second type set simultaneously.

[0010] This application discloses a method for a first node in wireless communication, comprising:

[0011] Receive a first signaling message, which is used to determine a first time-frequency resource;

[0012] Send a first signal in the first time-frequency resource;

[0013] Wherein, the first signaling is identified by a target RNTI; whether the target RNTI is used for scrambling the first signal is related to the type of the target RNTI; the type of the target RNTI belongs to one of a first type set and a second type set; when the type of the target RNTI belongs to the first type set, the target RNTI is used for scrambling the first signal, and when the type of the target RNTI belongs to the second type set, the target RNTI is not used for scrambling the first signal; only the first type set includes C-RNTI; no RNTI type belongs to both the first type set and the second type set simultaneously.

[0014] As an example, the above method is characterized in that: in traditional systems, the RNTI used to identify the PDCCH is often also used for scrambling the data channel scheduled by the PDCCH, while in the scheme proposed in this application, whether the data channel scheduled by the PDCCH is still scrambled using the RNTI that identifies the PDCCH depends on the type of the RNTI that identifies the PDCCH.

[0015] As an example, the above method is characterized by being applicable to M-TRP scenarios where two RNTIs of the same type other than C-RNTIs are not configured for a UE, in order to save the system's RNTI resources.

[0016] According to one aspect of this application, it includes:

[0017] Receive the first information block, which is generated at the protocol layer below the RRC layer;

[0018] In this context, the CORESET (Control Resource Set) where the first signaling is located is associated with a first identity; the first information block is used to determine that at least one CORESET is associated with a second identity, which is different from the first identity; the first identity and the second identity each identify a cell; the scrambling of the first signal is related to the type of the target RNTI only when the first time-frequency resource is located after the first effective time in the time domain, and the effective time of the first information block is the first effective time.

[0019] As an example, one feature of the above method is that: through a unified TCI, the reference signal is changed from being associated with the serving cell PCI to being associated with a PCI other than the serving cell PCI; at the same time, the first node still maintains the transmission of SPS or CS.

[0020] As an example, another feature of the above method is that the first node is assigned an RNTI for SPS or CS in the TRP or cell associated with the first identity, and the first node is not assigned an RNTI for SPS or CS in the TRP or cell associated with the second identity.

[0021] According to one aspect of this application, it includes:

[0022] Receive second signaling;

[0023] Wherein, the type of the target RNTI belongs to the second type set; the type of the RNTI used to identify the second signaling belongs to the first type set; the RNTI used to identify the second signaling is associated with the second identity; and the second signaling is used to deactivate or release the scheduling of the first signaling.

[0024] As an example, one feature of the above method is that the RNTI identifying the PDCCH used to activate SPS or CS transmission is different from the RNTI identifying the PDCCH used to deactivate / release the same SPS or CS transmission, so as to improve the flexibility of system implementation.

[0025] According to one aspect of this application, it includes:

[0026] Channel monitoring is performed on K2 candidate time-frequency resources;

[0027] Wherein, the first node receives a first signal in the first time-frequency resource, the first signaling is used to determine K1 candidate time-frequency resources, where K1 is a positive integer greater than 1; any one of the K2 candidate time-frequency resources is one of the K1 candidate time-frequency resources; K2 is a positive integer not greater than K1; the channel monitoring performed in the K2 candidate time-frequency resources is used to determine whether the scheduling indicated by the first signaling is deactivated or released.

[0029] Receive the first message;

[0030] Wherein, the first message is used to configure at least the target RNTI; the first message includes a first RNTI and a second RNTI, the types of the first RNTI and the second RNTI both belong to a first type set; the first RNTI and the second RNTI are respectively associated with the first identity and the second identity; the second signaling is identified by the second RNTI.

[0031] As an example, one feature of the above method is that, without affecting the transmission of SPS / CS, the first node is configured with two C-RNTIs for scheduling two TRPs or cells respectively, but is not configured with two CS-RNTIs (Configured Scheduling RNTIs) / SPS-RNTIs (Semi-static Scheduling Radio Network Temporary Identifiers), thus not increasing the overhead of additional RNTIs.

[0041] As an example, the above method is characterized in that: when the reference signal of the unified TCI indication changes from being associated with the serving cell PCI to being associated with a PCI other than the serving cell PCI, the reference signal of the unified TCI indication is used to determine the spatial characteristics of the data channel after the unified TCI effective time.

[0176] Example 3

[0177] 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 for 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) 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 herein as PHY 301. Layer 2 (L2 layer) 305 sits above PHY 301 and is responsible for the link between the first and second communication node devices via PHY 301. Layer 2 305 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 communication node device. 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 the first and second communication node devices. 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. 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 layers 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.).

[0207] Example 4

[0208] 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 450 and a second communication device 410 communicating with each other in the access network.

[0209] 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.

[0210] 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.

[0211] 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.

[0212] 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 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.

[0213] 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.

[0214] 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.
