Description

Technical Field

[0001] The present application relates to a transmission method and apparatus in a wireless communication system, and particularly to a transmission scheme and apparatus with a flexible transmission direction in wireless communication. Background Art

[0002] The application scenarios of future wireless communication systems are becoming increasingly diversified, and different application scenarios pose different performance requirements on the system. To meet the different performance requirements of various application scenarios, it was decided at the 72nd plenary session of 3GPP (3rd Generation Partner Project) RAN (Radio Access Network) to conduct research on the new air interface technology (NR, New Radio) (or 5G). At the 75th plenary session of 3GPP RAN, the WI (Work Item) of the new air interface technology (NR, New Radio) was adopted, and the standardization work of NR began. At the 86th plenary session of 3GPP RAN, it was decided to start the SI (Study Item) and WI (Work Item) of NR Rel-17, and at the 94th e plenary session of 3GPP RAN, the SI and WI of NR Rel-18 were approved. At the 102nd plenary session of 3GPP RAN, it was decided to start the SI and WI of NR Rel-19.

[0003] In NR Rel-19, there is a WI that supports subband non-overlapping full duplex (SBFD). Subband non-overlapping full duplex is also one of the technologies potentially supported by 6G. Summary of the Invention

[0004] In the existing NR system, spectrum resources are statically divided into FDD spectrum and TDD spectrum. For the TDD spectrum, both the base station and the user equipment operate in a half-duplex mode. This half-duplex mode avoids self-interference and can mitigate the impact of cross-link interference, but it also leads to a decrease in resource utilization and an increase in latency. To address these issues, supporting a flexible duplex mode on the TDD spectrum or FDD spectrum becomes a possible solution.

[0005] Regarding the configuration problem of supporting flexible duplex modes, this application discloses a solution. It should be noted that in the description of this application, the flexible duplex mode is only taken as a typical application scenario or example; this application is also equally applicable to 6G networks or other scenarios facing similar problems (such as scenarios where the 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 scenarios supporting full-duplex on the same frequency, or for different application scenarios, such as eMBB, URLLC, non-terrestrial networks, integrated communication and sensing networks, intelligent metasurfaces, terahertz networks, and similar technical effects can also be achieved. In addition, adopting a unified solution for different scenarios (including but not limited to scenarios of eMBB, URLLC, non-terrestrial networks, integrated communication and sensing networks, intelligent metasurfaces, terahertz networks) helps to reduce hardware complexity and cost.

[0352] Example 3

[0353] Example 3 shows a schematic diagram of the radio protocol architecture of the user plane and the control plane according to an embodiment of the present application, as shown in the Figure 3 appendix. Figure 3 FIG. is a schematic diagram illustrating an embodiment of the radio protocol architecture for the user plane 350 and the control plane 300, Figure 3The radio protocol architecture of the control plane 300 for a terminal (UE or gNB) and a base station (gNB or UE) is shown in 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 as PHY 301 in this text. Layer 2 (L2 layer) 305 is above PHY 301 and is responsible for the link between the terminal and the base station through 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, and these sublayers terminate at the base station. The PDCP sublayer 304 provides multiplexing between different radio bearers and logical channels. The PDCP sublayer 304 also provides security by encrypting data packets and provides handover support for the terminal between base stations. The RLC sublayer 303 provides segmentation and reassembly of upper layer data packets, retransmission of lost data packets, and reordering of data packets to compensate for out-of-order reception due to HARQ. The MAC sublayer 302 provides multiplexing between logical and transport channels. The MAC sublayer 302 is also responsible for allocating various radio resources (e.g., resource blocks) in a cell among terminals. The MAC sublayer 302 is also responsible for HARQ operations. The RRC (Radio Resource Control) sublayer 306 in Layer 3 (L3 layer) of the control plane 300 is responsible for obtaining radio resources (i.e., radio bearers) and configuring the lower layers using RRC signaling between the base station and the terminal. The radio protocol architecture of the user plane 350 includes Layer 1 (L1 layer) and Layer 2 (L2 layer). In the user plane 350, the radio protocol architecture for the terminal and the base station is generally the same as the corresponding layers and sublayers in the control plane 300 for the physical layer 351, the PDCP sublayer 354 in the L2 layer 355, the RLC sublayer 353 in the L2 layer 355, and the MAC sublayer 352 in the L2 layer 355, but the 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, and the SDAP sublayer 356 is responsible for the mapping between QoS flows and data radio bearers (DRBs) to support service diversity.Although not shown, the terminal may have several upper layers above the L2 layer 355, including a network layer (e.g., IP layer) that terminates at the P-GW on the network side and an application layer that terminates at the other end of the connection (e.g., a remote UE, a server, etc.).

[0362] Example 4

[0363] Example 4 shows a schematic diagram of a terminal and a base station according to an embodiment of the present application, as shown in Figure 4 shown.

[0364] The terminal (450) may include a controller / processor 490, a data source / cache 480, a receiving processor 452, a transmitter / receiver 456, and a transmitting processor 455. The transmitter / receiver 456 includes an antenna 460.

[0365] The base station (410) may include a controller / processor 440, a data source / cache 430, a receiving processor 412, a transmitter / receiver 416, and a transmitting processor 415. The transmitter / receiver 416 includes an antenna 420.

[0366] In DL (Downlink), the upper layer packets are provided to the controller / processor 440. The controller / processor 440 implements the functions of L2 layer and above layers. In DL, the controller / processor 440 provides header compression, encryption, packet segmentation and reordering, multiplexing between logical and transport channels, and radio resource allocation to the terminal 450 based on various priority metrics. The controller / processor 440 is also responsible for HARQ operations, retransmission of lost packets, and high layer signaling to the terminal 450. The high layer information carried by the first information block, the second information block, the third information block, and the first signaling (if the first signaling carries high layer information) 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 coding, interleaving, scrambling, modulation, power control / assignment, precoding, and generation of physical layer control signaling, etc. For example, the physical layer signals carrying the first information block in this application, the physical layer signals carrying the second information block in this application, the physical layer signals carrying the third information block in this application, and the first signaling in this application are completed by the transmit processor 415. The generated modulation symbols are divided into parallel streams and each stream is mapped to the corresponding multi-carrier sub-carriers and / or multi-carrier symbols, and then are mapped by the transmit processor 415 to the antennas 420 via the transmitter 416 and transmitted in the form of radio frequency signals. At the receiving end, each receiver 456 receives the radio frequency signals 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 receive processor 452. The receive processor 452 implements various signal receiving and processing functions for the L1 layer. The signal receiving and processing functions include demodulation of the physical layer signals carrying the first information block in this application, the physical layer signals carrying the second information block in this application, the physical layer signals carrying the third information block in this application, and the first signaling in this application, based on various modulation schemes (e.g., Binary Phase Shift Keying (BPSK), Quadrature Phase Shift Keying (QPSK)) through the multi-carrier symbols in the multi-carrier symbol stream, followed by descrambling, decoding, and deinterleaving to recover the data or control transmitted by the base station 410 on the physical channel, and then providing the data and control signals to the controller / processor 490. The controller / processor 490 is responsible for the L2 layer and above layers, and the controller / processor 490 interprets the high layer information. This includes interpreting the high layer information carried by the first information block, the second information block, the third information block, and the first signaling (if the first signaling carries high layer information) 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.

[0367] In the uplink (UL) transmission, similar to the downlink transmission, the high-layer information includes the first capability parameter in this application and the first PUSCH (if the first PUSCH carries high-layer information). After being generated by the controller / processor 490, the first capability parameter and the first PUSCH are processed by the transmitting processor 455 to perform various signal transmission processing functions for the L1 layer (i.e., the physical layer). The physical layer signal carrying the first capability parameter in this application and the first PUSCH in this application are mapped by the transmitting processor 455 via the transmitter 456 to the antenna 460 and transmitted in the form of 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 receiving processor 412. The receiving processor 412 performs various signal reception processing functions for the L1 layer (i.e., the physical layer), including receiving and processing the physical layer signal carrying the first capability parameter in this application and the first PUSCH in this application, and then provides the data and / or control signals to the controller / processor 440. The controller / processor 440 performs the functions of the L2 layer, including interpreting high-layer information such as the first capability parameter in this application and the first PUSCH (if the first PUSCH carries high-layer information). The controller / processor may be associated with a buffer 430 that stores program code and data. The buffer 430 can be a computer-readable medium.

[0533] Example 8

[0534] Example 8 exemplifies a schematic diagram of a second symbol, a first interval length, and an invalid symbol according to an embodiment of the present application, as shown in the attached Figure 8 figure. In the attached Figure 8 figure, the value of the first interval length is 2. Case A represents that when the first symbol is a non-full-duplex symbol, the second symbol is a full-duplex symbol, and when the first symbol is one of the two symbols after the second symbol, the first symbol is an invalid symbol for the first PUSCH; Case B represents that when the first symbol is a full-duplex symbol, the second symbol is a non-full-duplex symbol, and when the first symbol is one of the two symbols after the second symbol, the first symbol is an invalid symbol for the first PUSCH.

In the appendix Figure 13 shown, the processing device 1300 in the terminal includes a first transceiver 1301. The first transceiver 1301 includes the transmitter / receiver 456 (including antenna 460), a receive processor 452, a transmit processor 455, and a controller / processor 490 in the appendix of this application Figure 4 shown.

[0792] Example 14

The first information block indicates at least one full-duplex symbol. The second transceiver 1401 receives a first PUSCH.

Among them, the second information block configures a first SRS resource set and a second SRS resource set. The first SRS resource set includes at least one SRS resource, and the second SRS resource set includes at least one SRS resource. The N nominal repetitions are sequentially associated with the first SRS resource set and the second SRS resource set. A first nominal repetition is a nominal repetition among the N nominal repetitions that occupies two symbol types in the time domain. The symbol types include full-duplex symbols and non-full-duplex symbols. The first nominal repetition includes multiple actual repetitions. A first actual repetition is one of the multiple actual repetitions included in the first nominal repetition.

[0795] As an embodiment, the second transceiver 1401 transmits a third information block. Among them, the third information block indicates a third SRS resource set. When the first actual repetition only occupies non-full-duplex symbols in the time domain, the first actual repetition is associated with the SRS resource set associated with the first nominal repetition. Otherwise, the first actual repetition is associated with the third SRS resource set.

The second actual repetition only occupies non-full-duplex symbols in the time domain, and the second actual repetition is associated with the first SRS resource set.

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. The first interval length is predefined or configured. The symbols occupied by the multiple actual repetitions included in the first nominal repetition in the time domain are valid symbols for the first PUSCH.

[0798] As an example, the third symbol is the downlink symbol indicated by the latest TDD uplink-downlink configuration that is earlier than the first symbol and is not configured as a full-duplex symbol by the first information block. Whether the first symbol is an invalid symbol for the first PUSCH depends on that the interval length between the first symbol and the third symbol is less than or equal to a second interval length, and the second interval length is indicated by a high-layer parameter.

The first actual repetition includes a consecutive symbol set of full-duplex symbols or a consecutive symbol set of non-full-duplex symbols that are valid for the first PUSCH within a time slot.

[0800] As an example, the first PUSCH carries a first transport block, and the number of nominal repetitions including at least one full-duplex symbol among the N nominal repetitions is N1; the size of the first transport block depends on a second RE quantity. The first factor and the first RE quantity are jointly used to determine the second RE quantity, the first factor is related to N1, and the first RE quantity is equal to the number of REs occupied by the first PUSCH in one nominal repetition and one RB.
