Description

Technical Field

[0001] This application relates to transmission methods and apparatus in wireless communication systems, and more particularly to transmission schemes and apparatus with flexible transmission direction configurations in wireless communication. Background Technology

[0002] The application scenarios of future wireless communication systems are becoming increasingly diversified, and different application scenarios place different performance requirements on the system. To meet the diverse performance needs of various application scenarios, the 3GPP (3rd Generation Partner Project) RAN (Radio Access Network) #72 plenary meeting decided to conduct research on New Radio (NR) technology (or 5G). The 3GPP RAN #75 plenary meeting approved the WI (Work Item) for New Radio (NR) technology, initiating standardization work for NR. The 3GPP RAN #86 plenary meeting decided to begin work on the SI (Study Item) and WI (Work Item) for NRRel-17, and it is expected that the SI and WI for NRRel-18 will be approved at the 3GPP RAN #94e plenary meeting.

[0003] In new air interface technologies, enhanced mobile broadband (eMBB), ultra-reliable and low-latency communications (URLLC), and massive machine-type communications (mMTC) are three main application scenarios. Summary of the Invention

[0004] In existing NR systems, spectrum resources are statically divided into FDD and TDD spectrum. For TDD spectrum, both base stations and user equipment operate in half-duplex mode. This half-duplex mode avoids self-interference and mitigates cross-link interference, but it also leads to decreased resource utilization and increased latency. To address these issues, supporting flexible duplex modes on either TDD or FDD spectrum becomes a possible solution.

[0005] This application discloses a solution to the problem of determining the path loss of the probe reference signal under the enabled default beam in a flexible duplex mode. This application uses flexible duplex mode as a typical application scenario or example; it is also applicable to other scenarios facing similar problems (such as scenarios where the link direction changes, or other scenarios that support multi-level configuration of transmission direction, or scenarios with more capable base stations or user equipment, such as scenarios supporting full-duplex on the same frequency), or for different application scenarios, such as eMBB and URLLC, achieving similar technical effects. Furthermore, this application can also solve the problem of determining parameters other than path loss for detecting reference signals under the default beam, such as default scheduling parameters and default power parameters. Using a unified solution for different scenarios (including but not limited to eMBB and URLLC scenarios) or different application parameters also 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 be found in the definitions in the 3GPP specification protocols TS38 and TS37 series.

[0295] Example 3

[0296] 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.

[0297] 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 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. L2305 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 process number). The MAC sublayer 302 provides multiplexing between logical and transport channels. It is also responsible for allocating various radio resources (e.g., resource blocks) within a cell among the first communication node devices. The MAC sublayer 302 is also responsible for HARQ operations. The RRC (Radio Resource Control) sublayer 306 in L3 of the control plane 300 is responsible for obtaining radio resources (i.e., radio bearers) and configuring the lower layer using RRC signaling between the second communication node device and the first communication node device.The radio protocol architecture of user plane 350 includes Layer 1 (L1) and Layer 2 (L2). 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 L2355, RLC sublayer 353 in L2355, and MAC sublayer 352 in L2355. However, PDCP sublayer 354 also provides header compression for upper-layer data packets to reduce radio transmission overhead. L2355 in user plane 350 also includes SDAP (Service Data Adaptation Protocol) sublayer 356. SDAP sublayer 356 is responsible for mapping between QoS (Quality of Service) streams and Data Radio Bearer (DRB) to support service diversity. Although not illustrated, the first communication node device may have several upper layers above L2355, including a network layer (e.g., IP (Internet Protocol) layer) terminating at the P-GW on the network side and an application layer terminating at the other end of the connection (e.g., remote UE, server, etc.).

[0306] Example 4

[0307] Example 4 illustrates a schematic diagram of a first node device and a second node device according to an embodiment of this application, as shown in the attached diagram. Figure 4 As shown.

[0308] The first node device (450) may include a controller / processor 490, a data source / buffer 480, a receiver processor 452, a transmitter / receiver 456 and a transmitter processor 455, wherein the transmitter / receiver 456 includes an antenna 460.

[0309] The second node device (410) may include a controller / processor 440, a data source / buffer 430, a receiver processor 412, a transmitter / receiver 416 and a transmitter processor 415, wherein the transmitter / receiver 416 includes an antenna 420.

[0310] In the DL (Downlink), upper-layer packets are provided to the controller / processor 440. The controller / processor 440 implements the functions of Layer 2 and above. In the DL, the controller / processor 440 provides header compression, encryption, packet segmentation and reordering, multiplexing between the logical and transport channels, and radio resource allocation to the first node device 450 based on various priority metrics. The controller / processor 440 is also responsible for HARQ operation, retransmission of lost packets, and higher-layer signaling to the first node device 450. The higher-layer information carried by the first information block, the first signaling (if the first signaling carries higher-layer information), the second information block, X1 sub-information blocks, and the third information block in this application is generated by the controller / processor 440. The transmit processor 415 implements various signal processing functions for the L1 layer (i.e., the physical layer), including encoding, interleaving, scrambling, modulation, power control / distribution, precoding, and physical layer control signaling generation. For example, physical layer signals carrying a first information block, first signaling, physical layer signals carrying a second information block, physical layer signals carrying X1 sub-information blocks, and physical layer signals carrying a third information block are generated in the transmit processor 415. The generated modulation symbols are divided into parallel streams, and each stream is mapped to a corresponding multi-carrier subcarrier and / or multi-carrier symbol. These are then mapped by the transmit processor 415 to the antenna 420 via the transmitter 416 and transmitted as radio frequency signals. At the receiver, each receiver 456 receives the radio frequency signal through its corresponding antenna 460. Each receiver 456 recovers the baseband information modulated onto the radio frequency carrier and provides the baseband information to the receiver processor 452. The receiver processor 452 implements various signal reception processing functions for the L1 layer. The signal reception and processing function includes demodulating the physical layer signal carrying the first information block, the first signaling, the physical layer signal carrying the second information block, the physical layer signal carrying X1 sub-information blocks, and the physical layer signal carrying the third information block from the present application using multi-carrier symbols in a multi-carrier symbol stream based on various modulation schemes (e.g., Binary Phase Shift Keying (BPSK), Quadrature Phase Shift Keying (QPSK)). Subsequently, it performs descrambling, decoding, and deinterleaving to recover the data or control transmitted by the second node device 410 on the physical channel, and then provides the data and control signals to the controller / processor 490. The controller / processor 490 is responsible for the L2 layer and above, and interprets higher-layer information. This includes interpreting the higher-layer information carried by the first information block, the first signaling (if the first signaling carries higher-layer information), the second information block, the X1 sub-information blocks, and the third information block. The controller / processor may be associated with a memory 480 that stores program code and data. The memory 480 may be referred to as computer-readable media.

[0311] In uplink (UL) transmission, similar to downlink transmission, the higher-layer information, including the target reference signal in this application (when the target reference signal carries higher-layer information), is generated by the controller / processor 490 and then processed by the transmitter processor 455 to perform various signal transmission processing functions for the L1 layer (i.e., physical layer). The target reference signal is transmitted by the transmitter processor 455 via the transmitter 456 to the antenna 460 in the form of a radio frequency signal. The receiver 416 receives the radio frequency signal through its corresponding antenna 420. Each receiver 416 recovers the baseband information modulated onto the radio frequency carrier and provides the baseband information to the receiver processor 412. The receiver processor 412 implements various signal reception processing functions for the L1 layer (i.e., physical layer), including receiving and processing the target reference signal in this application, and subsequently providing data and / or control signals to the controller / processor 440. The controller / processor 440 implements L2 layer functions, including interpreting the higher-layer information, such as the higher-layer information carried by the target reference signal in this application (when the target reference signal carries higher-layer information). The controller / processor may be associated with a cache 430 that stores program code and data. The cache 430 may be computer-readable media.
