Description

Technical Field

[0001] This application relates to transmission methods and devices in a wireless communication system, and particularly to transmission schemes and devices for flexible transmission direction configuration in wireless communication. Background Art

[0002] The application scenarios of future wireless communication systems are becoming increasingly diverse, 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 approved, 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 it is expected to initiate the SI and WI of NR Rel-18 at the 94th e plenary session of 3GPP RAN. At the 102nd plenary session of 3GPP RAN, the SI and WI of NR Rel-19 were initiated, and the initiation of NR Rel-19 includes support for sub-band full duplex. Summary of the Invention

[0003] 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.

[0004] Regarding the problem of multiplexing UCI to PUSCH in support of 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 in the same frequency band, 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.

[0280] Example 3

[0281] Example 3 shows a schematic diagram of a radio protocol architecture for a user plane and a control plane according to the present application, as shown in the appended Figure 3 figure. Figure 3 It is a schematic diagram illustrating an example of a radio protocol architecture for a user plane 350 and a control plane 300. Figure 3The radio protocol architecture of the control plane 300 for the devices (UE or gNB) used for the first node and the devices (gNB or UE) used for the second node 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 PHY301 in this document. Layer 2 (L2 layer) 305 is above PHY301 and is responsible for the link between the first node device and the second node device through PHY301. Layer 2 305 includes a MAC (Medium Access Control) sublayer 302, an RLC (Radio Link Control Protocol) sublayer 303, and a PDCP (Packet Data Convergence Protocol) sublayer 304, and these sublayers terminate at the second node device. 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 first node device between the second node devices. 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 between the first node devices. 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 second node device and the first node device. The radio protocol architecture of the user plane 350 includes Layer 1 (L1 layer) and Layer 2 (L2 layer). For the radio protocol architecture for the first node device and the second node device in the user plane 350, 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 are generally the same as the corresponding layers and sublayers in the control plane 300, 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 (DRB, Data Radio Bearer) to support service diversity.Although not shown, the first node device 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.).

[0291] Example 4

[0292] Example 4 shows a schematic diagram of the first node device and the second node device according to an embodiment of this application, as shown in Figure 4 shown.

[0293] The first node device (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.

[0294] The second node device (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.

[0295] 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 first node device 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 first node device 450. The high layer information carried by the first information block, the second information block, and the third information block in this application is generated in 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 / 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, and the physical layer signals carrying the third information block in this application are completed in 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 antenna 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 reception processing functions of the L1 layer. The signal reception 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, and the physical layer signals carrying the third information block 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 second node device 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, 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.

[0296] In the uplink (UL) transmission, similar to the downlink transmission, the high-layer information includes the first capability information block in the present application and the first PUSCH in the present application (such as carrying high-layer information). After being generated by the controller / processor 490, it undergoes various signal transmission processing functions for the L1 layer (i.e., the physical layer) by the transmitting processor 455. The physical layer signal carrying the first capability information block in the present application and the first PUSCH in the present application are mapped by the transmitting processor 455 to the antenna 460 via the transmitter 456 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 information block in the present application and the first PUSCH in the present 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 information block in the present application and the first PUSCH in the present application (such as carrying high-layer information). The controller / processor can be associated with a buffer 430 that stores program code and data. The buffer 430 can be a computer-readable medium.

[0380] Example 6

[0381] Example 6 illustrates a schematic diagram of the target interval on the full-duplex sub-band symbol according to an embodiment of the present application, as shown in the appendix Figure 6 shown. In the appendix Figure 6 the vertical axis represents frequency, the rectangle represents the RE, the cross-filled rectangle represents the RE in the target RE set, and the target interval is represented by d.

[0382] In Example 6, the target interval is equal to the frequency interval between two adjacent REs in the target RE set on the target symbol, and the target interval depends on whether the target symbol is a full-duplex sub-band symbol.

[0383] As an example, considering that the frequency domain resources at the uplink sub-band edge on the full-duplex sub-band symbol are interfered by the downlink sub-band, determining the target interval according to whether it is a full-duplex sub-band symbol enhances the system robustness.

[0384] As an example, the target interval is used to determine the distribution of the REs in the target RE set on the target symbol in the present application.

[0385] As an example, the distribution of the REs in the target RE set on the target symbol in the present application depends on the target interval.

[0386] As an example, the target interval corresponds to the parameter d.

[0387] As an example, the unit of the target interval is RE.

[0388] As an example, the target interval is the number of subcarriers of the interval.

[0389] As an example, the meaning of two adjacent REs in the target RE set includes two REs with the smallest frequency domain interval in the target RE set.

[0390] As an example, two adjacent REs in the target RE set are two REs with adjacent indices in the target RE set.

[0392] As an example, two adjacent REs in the target RE set are two REs mapped by two adjacent modulation symbols in the modulation symbol sequence generated by the first control bit set.

[0393] As an example, the meaning of the frequency interval between two adjacent REs in the target RE set includes the frequency interval between REs in the target RE set.

[0394] As an example, the technical feature "the target interval is equal to the frequency interval between two adjacent REs in the target RE set on the target symbol" includes the following meaning: the target interval is the frequency interval of the REs in the target RE set on the target symbol.

[0395] As an example, the technical feature "the target interval is equal to the frequency interval between two adjacent REs in the target RE set on the target symbol" includes the following meaning: the target interval is equal to the number of subcarriers separated in the frequency domain by the REs occupied by the first control bit set in this application on the target symbol.

[0396] As an example, the technical feature "the target interval is equal to the frequency interval between two adjacent REs in the target RE set on the target symbol" includes the following meaning: the target interval is equal to the frequency domain interval between the REs mapped by the first control bit set in this application onto the target symbol.

[0397] As an example, the technical feature "the target interval is equal to the frequency interval between two adjacent REs in the target RE set on the target symbol" includes the following meaning: on the target symbol, the target RE set contains several REs, and the frequency domain interval between each pair of adjacent REs is the target interval.

[0398] As an example, the technical feature "the target interval is equal to the frequency interval between two adjacent REs in the target RE set on the target symbol" includes the following meaning: on the target symbol, the target RE set contains several REs, and the frequency domain interval between a pair of adjacent REs is the target interval.

[0634] As an embodiment, the target interval is equal to the frequency interval between two adjacent REs belonging to the target RE set on the target symbol, and the target interval depends on whether the target symbol is a full-duplex sub-band symbol.

[0635] As an embodiment, the frequency domain position of the starting RE belonging to the target RE set on the target symbol in the first time-frequency resource set depends on at least one of the frequency domain position of the REs in the first time-frequency resource set on the target symbol in the uplink sub-band and the frequency domain position relationship between the uplink sub-band and the downlink sub-band.

[0636] As an embodiment, the REs belonging to the first time-frequency resource set on the target symbol are arranged in a first RE sequence according to the distance from the downlink sub-band. The first set of control bits is mapped to the first X REs in the first RE sequence, where X is a positive integer greater than 1. The number of bits transmitted on the REs earlier than the target symbol in the target RE set, the number of bits included in the first set of control bits, and the number of REs belonging to the first time-frequency resource set on the target symbol are jointly used to determine X.

[0637] As an embodiment, the second transceiver 1301 receives a third information block. The third information block indicates a first parameter. A first subset of bits is used to generate the first set of control bits. The first subset of bits includes at least one information bit. The first subset of bits, the first parameter, and the number of REs in the first time-frequency resource set that do not overlap with the demodulation reference signal (DMRS) in the time domain are jointly used to determine the number of bits in the first set of control bits, and the first parameter depends on whether the target symbol is a full-duplex sub-band symbol.

[0638] As an example, the target RE set starts from the first symbol after the set of consecutive symbols carrying DMRS in the first time-frequency resource set in the time domain, and occupies Y symbols not carrying DMRS, where Y is a positive integer greater than 1; the target symbol is the latest symbol among the Y symbols not carrying DMRS, and the interval between adjacent REs included in any symbol before the target symbol in the target RE set is equal to a predefined value.

[0639] As an example, the second transceiver 1301 transmits a first capability information block, and the first capability information block indicates that the sender of the first PUSCH supports multiplexing the first set of control bits onto the first time-frequency resource set on the full-duplex sub-band symbol.
