Description

A method and apparatus for a node used in wireless communication 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) (or 5G). The 3GPP RAN #75 plenary meeting approved the NR Work Item (WI), initiating standardization work for NR. The 3GPP RAN #86 plenary meeting decided to begin work on the NR Rel-17 Study Item (SI) and Work Item (WI), and the 3GPP RAN #94e plenary meeting initiated the NR Rel-18 SI and WI projects. The 3GPP RAN #102 plenary meeting decided to begin work on the NR Rel-19 SI and WI.

[0003] NRRel-19 includes Wi-Fi support for Subband Non-Overlapping Full Duplex (SBFD). SBFD is also one of the technologies that 6G may support. 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] To address the configuration issue of uplink transmission supporting flexible duplex modes, this application discloses a solution. It should be noted that the flexible duplex mode described in this application is merely a typical application scenario or example; this application is also applicable to 6G networks or other scenarios facing similar problems (e.g., scenarios where link direction changes, or other scenarios supporting multi-level configuration of transmission directions, or scenarios with more capable base stations or user equipment, such as those supporting full-duplex on the same frequency), or for different application scenarios, such as eMBB, URLLC, non-terrestrial networks, sensor-integrated networks, smart metasurfaces, and terahertz networks, achieving similar technical effects. Furthermore, adopting a unified solution for different scenarios (including but not limited to eMBB, URLLC, non-terrestrial networks, sensor-integrated networks, smart metasurfaces, and terahertz networks) helps reduce hardware complexity and cost. Where there is no conflict, the embodiments and features described in the device used as the first node can be applied to the device used as the second node, and vice versa.

Figure 3 is a schematic diagram illustrating an embodiment of the radio protocol architecture for user plane 350 and control plane 300. Figure 3 shows the radio protocol architecture of control plane 300 for a first node device (UE or gNB) and a second node device (gNB or UE) 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. The L1 layer will be referred to herein as PHY 301.

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, second, and third information blocks in this application is generated in the controller / processor 440. The transmit processor 415 implements various signal processing functions for Layer 1 (i.e., physical layer), including encoding, interleaving, scrambling, modulation, power control / allocation, precoding, and physical layer control signaling generation, such as the physical layer signal carrying the first information block, the physical layer signal carrying the second information block in this application, and the physical layer signal carrying the third information block in this application, which are completed in the transmit processor 415. The generated modulation symbols are divided into parallel streams, and each stream is mapped to a corresponding multicarrier subcarrier and / or multicarrier symbol. These are then transmitted by the transmit processor 415 via the transmitter 416 to the antenna 420 as radio frequency (RF) signals. At the receiver, each receiver 456 receives the RF signal through its corresponding antenna 460. Each receiver 456 recovers the baseband information modulated onto the RF carrier and provides the baseband information to the receive processor 452. The receive processor 452 implements various signal reception processing functions of the L1 layer. These signal reception processing functions include demodulating the physical layer signals carrying the first information block, the second information block, and the third information block of the present application using multicarrier symbols in the multicarrier symbol stream based on various modulation schemes (e.g., Binary Phase Shift Keying (BPSK), Quadrature Phase Shift Keying (QPSK)), followed by descrambling, decoding, and deinterleaving to recover the data or control transmitted by the second node device 410 on the physical channel. The data and control signals are then provided to the controller / processor 490. The controller / processor 490 is responsible for the L2 layer and above, and interprets high-level information. This includes interpreting the high-level information carried in the first information block, the second information block, and the third information block in this application. The controller / processor may be associated with a memory 480 that stores program code and data. The memory 480 may be referred to as a computer-readable medium.

[0273] In uplink (UL) transmission, similar to downlink transmission, higher-layer information, including the first capability parameters and the first PUSCH (carrying higher-layer information) as described in this application, 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 physical layer signal carrying the first capability parameters and the first PUSCH are transmitted by the transmitter processor 455 via the transmitter 456 to the antenna 460 as radio frequency signals. The receiver 416 receives the radio frequency signals 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 physical layer signal carrying the first capability parameters and the first PUSCH, and then providing data and / or control signals to the controller / processor 440.

[0445] Example 9

[0446] Example 9 illustrates a schematic diagram of the fourth symbol, third interval length, and invalid symbol according to an embodiment of this application, as shown in Figure 9. In Figure 9, D represents a downlink symbol configured for TDD uplink / downlink, F represents a flexible symbol configured for TDD uplink / downlink, U represents an uplink symbol configured for TDD uplink / downlink, blank-filled rectangles represent non-full-duplex symbols, cross-filled rectangles represent full-duplex symbols, the fourth symbol is the latest first-class SSB symbol, and when the value of the third interval length is 2, the two time-domain symbols following the fourth symbol are invalid for the first PUSCH.

[0447] In embodiment 9, the fourth symbol is the latest first-class SSB symbol that is earlier than the first symbol. The first-class SSB symbol is a time-domain symbol that is configured with a full-duplex sub-band by the second information block and is received by priority SSB. The first symbol is an invalid symbol for the first PUSCH that depends on the time-domain interval length between the first symbol and the fourth symbol being less than or equal to a third interval length, which is predefined or depends on the capability of the first node.

[0448] As an example, consider setting a full-duplex sub-band in the SSB symbol. When uplink transmission can be carried out in the first type of SSB symbol using the configured full-duplex sub-band, a downlink-to-uplink conversion time interval is set after the time domain symbol received by the priority SSB, which introduces a flexible duplex mode while being compatible with existing standards.

[0449] As one example, the preferential SSB reception and disallowing uplink transmission are equivalent or interchangeable.

[0450] As an example, the fourth symbol does not belong to the first symbol set.

[0464] As one embodiment, the first type of SSB symbols includes a subset of SSB symbols. As a supplementary embodiment, some SSB symbols do not belong to the first type of SSB symbols.

The advantage of this is that it ensures the reception of important SSBs while improving uplink transmission performance.

[0465] As one embodiment, the first type of SSB symbol includes symbols carrying an SSB indexed by the "ssb-PositionsInBurst" field in the IE "SSB-MTC-AdditionalPCI". As a supplementary embodiment, the advantage of doing so is that the SSB used for measurement is protected.

[0468] As an example, the first type of SSB symbol is an SSB symbol that carries the PSS (Primary Synchronization Signal) sequence and the SSS (Secondary Synchronization Signal) sequence indicating the PCI of the serving cell.

[0470] As an example, the full-duplex sub-band is an SBFD sub-band.

[0471] As an example, the full-duplex sub-band is the uplink SBFD sub-band.

[0576] As an example, a symbol indicated as a downlink by tdd-UL-DL-ConfigurationCommon or tdd-UL-DL-ConfigurationDedicated and indicated as a non-SBFD symbol is considered an invalid symbol for PUSCH repeating type B transmission.

[0577] As an example, a symbol indicated by tdd-UL-DL-ConfigurationCommon or tdd-UL-DL-ConfigurationDedicated as not being configured as an SBFD symbol for the downlink is considered an invalid symbol for PUSCH repeat type B transmission.

[0580] Example 12 illustrates a structural block diagram of a processing device in a first node according to an embodiment, as shown in Figure 12. In Figure 12, the processing device 1200 in the first node includes a first transceiver 1201. The first transceiver 1201 includes a transmitter / receiver 456 (including an antenna 460) as shown in Figure 4 of this application, a receiving processor 452, a transmitting processor 455, and a controller / processor 490.

[0581] In embodiment 12, a first transceiver 1201 receives a first information block and a second information block. The first information block indicates at least one full-duplex symbol, and the second information block indicates a first symbol set, which includes at least one time-domain symbol. The first transceiver 1201 transmits a first PUSCH. Any symbol occupied by the first PUSCH in the time domain belongs to the first symbol set. The first symbol is a symbol in the first symbol set, and the second symbol is the latest symbol that is earlier than the first symbol and has a different symbol type. The validity of the first symbol for the first PUSCH depends on the interval length between the first symbol and the second symbol. The symbol type includes full-duplex symbols and non-full-duplex symbols.

[0582] As an example, the first symbol being an invalid symbol for the first PUSCH depends on the interval length between the first symbol and the second symbol being less than or equal to a first interval length, which is configured or predefined.

[0583] As an example, the first transceiver 1201 receives a third information block; wherein the third symbol is a downlink symbol indicated by the latest TDD uplink / downlink configuration earlier than the first symbol and is not configured as a full-duplex symbol by the first information block, the first symbol is an invalid symbol for the first PUSCH depending on the interval length between the first symbol and the third symbol being less than or equal to a second interval length, and the third information block indicates the second interval length.

[0584] As one embodiment, the first transceiver 1201 transmits a first capability parameter; wherein the first capability parameter indicates the uplink / downlink switching time of the sender of the first capability parameter, and the second interval length depends on the first capability parameter.

[0585] As an example, the fourth symbol is the latest first-class SSB symbol that is earlier than the first symbol. The first-class SSB symbol is a time-domain symbol that is configured with a full-duplex sub-band and is preferentially received by the second information block. The first symbol is an invalid symbol for the first PUSCH that depends on the time-domain interval length between the first symbol and the fourth symbol being less than or equal to a third interval length, which is predefined or depends on the capabilities of the first node.

[0586] As an example, the first symbol set is the set of symbols occupied by N nominal repetitions of the first PUSCH, where N is a positive integer, the first nominal repetition is one nominal repetition among the N nominal repetitions of the first PUSCH, more than one symbol among the symbols occupied by the first nominal repetition is a valid symbol for the first PUSCH, the first nominal repetition includes one or more actual repetitions of the first PUSCH, and one actual repetition of the first PUSCH includes a continuous set of full-duplex symbols or a continuous set of non-full-duplex symbols valid for the first PUSCH within a time slot.

[0587] As an example, the first symbol is a downlink symbol indicated by the TDD uplink / downlink configuration, and the first symbol is an invalid symbol for the first PUSCH depending on the fact that the first symbol was not configured as a full-duplex symbol by the first information block.

The second transceiver 1301 receives a first PUSCH. Any symbol occupied by the first PUSCH in the time domain belongs to the first symbol set. The first symbol is a symbol in the first symbol set, and the second symbol is the latest symbol that is earlier than the first symbol and has a different symbol type. The validity of the first symbol for the first PUSCH depends on the interval length between the first symbol and the second symbol. The symbol type includes full-duplex symbols and non-full-duplex symbols.

[0591] As an example, the first symbol being an invalid symbol for the first PUSCH depends on the interval length between the first symbol and the second symbol being less than or equal to a first interval length, which is configured or predefined.

[0592] As an example, the first transceiver 1301 transmits a third information block; wherein the third symbol is a downlink symbol indicated by the latest TDD uplink / downlink configuration earlier than the first symbol and is not configured as a full-duplex symbol by the first information block, the first symbol is an invalid symbol for the first PUSCH depending on the interval length between the first symbol and the third symbol being less than or equal to a second interval length, and the third information block indicates the second interval length.

[0593] As one embodiment, the first transceiver 1301 receives a first capability parameter; wherein the first capability parameter indicates the uplink / downlink switching time of the sender of the first capability parameter, and the second interval length depends on the first capability parameter.

[0594] As an example, the fourth symbol is the latest first-class SSB symbol that is earlier than the first symbol. The first-class SSB symbol is a time-domain symbol that is configured with a full-duplex sub-band and is preferentially received by the second information block. The first symbol is an invalid symbol for the first PUSCH that depends on the time-domain interval length between the first symbol and the fourth symbol being less than or equal to a third interval length, which is predefined or depends on the capabilities of the first node.

[0595] As an example, the first symbol set is the set of symbols occupied by N nominal repetitions of the first PUSCH, where N is a positive integer, the first nominal repetition is one nominal repetition among the N nominal repetitions of the first PUSCH, more than one symbol among the symbols occupied by the first nominal repetition is a valid symbol for the first PUSCH, the first nominal repetition includes one or more actual repetitions of the first PUSCH, and one actual repetition of the first PUSCH includes a continuous set of full-duplex symbols or a continuous set of non-full-duplex symbols valid for the first PUSCH within a time slot.

[0596] As an example, the first symbol is a downlink symbol indicated by the TDD uplink / downlink configuration, and the first symbol is an invalid symbol for the first PUSCH depending on the fact that the first symbol was not configured as a full-duplex symbol by the first information block.
