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) (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 it is expected that the NR Rel-18 SI and WI 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 link direction configuration problem in flexible duplex mode. It should be noted that the description in this application uses flexible duplex mode as a typical application scenario or example; this application is also applicable to other scenarios facing similar problems (e.g., scenarios where link direction changes, or other scenarios supporting multi-level configuration of transmission direction, or scenarios with more capable base stations or user equipment, such as supporting full-duplex on the same frequency), or for different application scenarios, such as eMBB and URLLC, achieving similar technical effects. Furthermore, adopting a unified solution for different scenarios (including but not limited to eMBB and URLLC 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 specification protocols TS36, TS38, and TS37 series.

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

[0007] The system receives a first information block and a second information block. The first information block is used to determine X1 time-domain symbols corresponding to a first link direction, and the second information block is used to determine X2 time-domain symbols corresponding to a second link direction. X1 is a positive integer greater than 1, and X2 is a positive integer greater than 1. The first link direction and the second link direction are not the same.

[0008] Determine the target link direction and operate on the target signal in the target time-frequency resource set, the target time-frequency resource set including at least one time-domain symbol in the time domain, the link direction of any time-domain symbol included in the target time-frequency resource set in the time domain is the target link direction, the operation is receiving or the operation is transmitting;

[0009] Wherein, the time-domain symbol included in the target time-frequency resource set in the time domain is one of the X1 time-domain symbols, and the time-domain symbol included in the target time-frequency resource set in the time domain is one of the X2 time-domain symbols; the first link direction is one of uplink or downlink, and the second link direction is one of uplink, downlink, or flexible link; any subcarrier included in the target time-frequency resource set in the frequency domain belongs to the target sub-frequency band, and the configuration information of the target sub-frequency band is used to determine the target link direction, which is one of the first link direction or the second link direction.

[0010] As an example, the target link direction is determined based on the configuration information of the target sub-band, thereby supporting flexible duplex modes configured separately for each band. This provides frequency domain coordination capabilities to reduce self-interference and cross-link interference, improves transmission performance, and reduces the impact on traditional users.

[0011] As an example, the second information block is allowed to override the uplink and downlink symbols configured in the first information block in the target subband. This reduces interference and provides more flexible link direction configuration, thereby increasing scheduling flexibility and improving resource utilization.

[0012] According to one aspect of this application, the method is characterized in that the first information block is used to indicate the number of first symbols, the number of second symbols, and the configuration period length; at least one of the X1 time-domain symbols belongs to a first time window, the duration of the first time window being equal to the configuration period length; the number of time-domain symbols belonging to the first time window among the X1 time-domain symbols is equal to the number of first symbols, or the number of time-domain symbols belonging to the first time window among the X1 time-domain symbols is equal to the number of second symbols; the number of first symbols is a non-negative integer, the number of second symbols is a non-negative integer, and the configuration period length is greater than 0.

[0013] According to one aspect of this application, the above method is characterized by comprising:

[0014] Receive the third information block;

[0015] The third information block is used to determine the configuration information of the target sub-frequency band, which includes at least one of the target sub-frequency band's location information in the frequency domain and the target sub-frequency band's link direction indication. The target sub-frequency band's link direction indication is used to determine whether the second information block can overwrite the link direction of the uplink time domain symbol or downlink time domain symbol configured in the first information block.

[0016] As an example, the system determines whether the second information block can overwrite the first information block based on the frequency domain location or link direction indication of the target sub-band. This takes into account the self-interference and cross-link interference caused by adjacent channel leakage due to flexible duplexing, as well as the flexibility of configuration, and balances interference suppression and scheduling flexibility to optimize system performance.

[0017] According to one aspect of this application, the above method is characterized in that the target sub-band includes a subcarrier belonging to the first BWP in the frequency domain, the index of the second BWP is equal to the index of the first BWP, and the link direction corresponding to the first BWP is different from the link direction corresponding to the second BWP; at least one of the following is used to determine the target link direction from the first link direction or the second link direction: whether there are overlapping frequency domain resources between the target sub-band and the initial BWP, whether there are overlapping frequency domain resources between the target sub-band and the default BWP, and whether the center frequency of the first BWP and the center frequency of the second BWP are equal.

[0018] As an example, the relationship between the frequency band supporting flexible duplex and the initial BWP or default BWP, or the relationship between the center frequencies of the included uplink and downlink BWPs, determines whether the link direction of the traditional configuration can be overwritten, thereby avoiding the impact on traditional transmission and ensuring the backward compatibility of the system.

[0020] As an example, the time slot format supports uplink time domain symbols preceding downlink time domain symbols, thereby enabling more flexible support for link direction configuration, maximizing the scheduling freedom of flexible duplex, and further improving resource utilization and system performance.

[0121] As an example, the statement in the claim "the first information block is used to determine X1 time-domain symbols corresponding to the first link direction" includes the following meaning: the first information block is used by the first node device in this application to determine the X1 time-domain symbols corresponding to the first link direction.

[0122] As an example, the statement in the claim "the first information block is used to determine X1 time-domain symbols corresponding to the first link direction" includes the following meaning: all or part of the first information block is used to explicitly or implicitly indicate the X1 time-domain symbols corresponding to the first link direction.

[0123] As an example, the statement in the claim "the first information block is used to determine X1 time-domain symbols corresponding to the first link direction" includes the following meaning: the first information block is used to indicate the X1 time-domain symbols and the first information block is used to indicate that the X1 time-domain symbols correspond to the first link direction.

[0124] As an example, the statement in the claim "the first information block is used to determine X1 time-domain symbols corresponding to the first link direction" includes the following meaning: the first information block is used to indicate the number of time-domain symbols corresponding to the first link direction within a time window.

[0125] As an example, the statement in the claim "the first information block is used to determine X1 time-domain symbols corresponding to the first link direction" includes the following meaning: the first information block is used to indicate that the number of time-domain symbols corresponding to the first link direction within a time window is equal to X1, and the X1 time-domain symbols are the earliest or latest X1 time-domain symbols within the time window.

[0126] As an example, the statement in the claim that "the first information block is used to determine X1 time-domain symbols corresponding to the first link direction" is implemented by claim 2 of this application.

[0127] As an example, the first information block includes the default configuration of the link direction of the X1 time-domain symbols.

[0128] As an example, the actual link direction of transmission for at least one of the X1 time-domain symbols in the time domain is the first link direction.

[0129] As an example, the actual link direction of transmission in which at least one of the X1 time-domain symbols is occupied in the time domain and the subcarrier occupied in the frequency domain belongs to a sub-frequency band outside the target sub-frequency band is the first link direction.

[0130] As an example, the actual link direction of transmission occupying at least one of the X1 time-domain symbols in the time domain is not necessarily the first link direction.

[0131] As an example, each of the X1 time-domain symbols is configured by the first information block to adopt the time-domain symbol of the first link direction.

[0132] As an example, when the configuration of the link direction included in the first information block is not overridden, the actual link direction of transmission occupying at least one of the X1 time domain symbols in the time domain is the first link direction.

[0133] As an example, the link direction of each time-domain symbol whose link direction is not overwritten among the X1 time-domain symbols is the first link direction.

[0134] As an example, the link direction of the time domain symbol whose link direction is overwritten among the X1 time domain symbols is determined by the overwriting configuration.

[0135] As an example, the first link direction is the link direction indicated by the first information block for the X1 time-domain symbols, which is related to the actual link direction of transmission occupying at least one of the X1 time-domain symbols in the time domain, whether the occupied time-domain symbol is overwritten by other configurations, and / or whether the occupied subcarrier in the frequency domain belongs to the target sub-frequency band.

[0311] Example 3

[0312] 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 node device (UE or gNB) and the second node device (gNB or UE) 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. L1 layer will be referred to herein as PHY301. Layer 2 (L2 layer) 305 sits above PHY301 and is responsible for the link between the first and second node devices via PHY301. L2 layer 305 includes the MAC (Medium Access Control) sublayer 302, the RLC (Radio Link Control) sublayer 303, and the 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. The PDCP sublayer 304 also provides security through encrypted data packets and supports cross-regional mobility between the second node devices and the first node device. 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 among first-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 layer using RRC signaling between the second-node devices and the first-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 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 packets to reduce radio transmission overhead. L2 layer 355 in user plane 350 also includes SDAP (Service Data Adaptation Protocol) sublayer 356. SDAP sublayer 356 is responsible for mapping between QoS flows and Data Radio Bearers (DRBs) to support service diversity.Although not illustrated, the first node device may have several upper layers above 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., remote UE, server, etc.).

[0320] Example 4

[0321] 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.

[0322] 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.

[0323] 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.

[0324] In the DL (Downlink), upper-layer packets are provided to the controller / processor 440. The controller / processor 440 implements L2 and higher-layer functions. In the 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 higher-layer signaling to the first node device 450. The first information block, second information block, third information block, and higher-layer information carried by the target signal (when the target signal is a downlink transmission) in this application are 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 / distribution, precoding, and physical layer control signaling generation. For example, the generation of physical layer signals carrying a first information block, physical layer signals carrying a second information block, physical layer signals carrying a third information block, physical layer signals for the target signal (when the target signal is a downlink transmission), and the first signaling 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 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 receiving the physical layer signal carrying the first information block, the second information block, the third information block, the target signal (when the target signal is a downlink transmission), and the first signaling in this application. It demodulates the signals using various modulation schemes (e.g., Binary Phase Shift Keying (BPSK) and Quadrature Phase Shift Keying (QPSK)) through multicarrier symbols in the multicarrier 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. The data and control signals are then provided to the controller / processor 490. The controller / processor 490 is responsible for Layer 2 and above, and interprets higher-layer information. This includes interpreting the higher-layer information carried by the first, second, and third information blocks and the target signal (when the target signal is a downlink transmission). 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.

[0325] In uplink (UL) transmission, similar to downlink transmission, higher-layer information, including the higher-layer information carried by the target signal in this application (when the target signal is an uplink transmission), is generated by controller / processor 490 and then processed by transmitter processor 455 for various signal transmission processing functions for the L1 layer (i.e., physical layer). The physical layer signal of the target signal is mapped by transmitter processor 455 to antenna 460 via transmitter 456 and transmitted as a radio frequency signal. 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 receiver processor 412. 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 target signal in this application, and subsequently providing data and / or control signals to controller / processor 440. The L2 layer functions implemented in controller / processor 440 include interpreting higher-layer information, such as the higher-layer information carried by the target signal in this application (when the target signal is an uplink transmission). The controller / processor may be associated with a cache 430 that stores program code and data. The cache 430 may be computer-readable media.

[0479] As an example, the statement in the claim that "the configuration information of the target sub-band includes at least one of the target sub-band's location information in the frequency domain and the link direction indication of the target sub-band" includes the following meaning: the configuration information of the target sub-band includes the target sub-band's location information in the frequency domain, or the target sub-band's link direction indication, which includes only the target sub-band's location information in the frequency domain.

[0480] As an example, the statement in the claim that "the configuration information of the target sub-band includes at least one of the target sub-band's location information in the frequency domain and the link direction indication of the target sub-band" includes the following meaning: the configuration information of the target sub-band includes the target sub-band's location information in the frequency domain, or the link direction indication of the target sub-band, only the link direction indication of the target sub-band.

[0481] As an example, the configuration information of the target sub-band includes at least one of the following: the location information of the target sub-band in the frequency domain and the link direction indication of the target sub-band.

[0482] As an example, the configuration information of the target sub-band may also include configuration information other than the location information of the target sub-band in the frequency domain or the link direction indication of the target sub-band.

[0483] As an example, the statement in the claim that "the link direction indication of the target sub-band is used to determine whether the second information block can overwrite the link direction of the uplink time domain symbol or downlink time domain symbol configured in the first information block" includes the following meaning: the link direction indication of the target sub-band is used by the first node device in this application to determine whether the second information block can overwrite the link direction of the uplink time domain symbol or downlink time domain symbol configured in the first information block.

[0484] As an example, the statement in the claim that "the link direction indication of the target sub-band is used to determine whether the second information block can override the link direction of the uplink time domain symbol or downlink time domain symbol configured in the first information block" includes the following meaning: the link direction indication of the target sub-band is used to explicitly or implicitly indicate whether the second information block can override the link direction of the uplink time domain symbol or downlink time domain symbol configured in the first information block.

[0485] As an example, the statement in the claim that "the link direction indication of the target sub-band is used to determine whether the second information block can override the link direction of the uplink time domain symbol or downlink time domain symbol configured in the first information block" includes the following meaning: the link direction indication of the target sub-band is used to explicitly or implicitly switch the link direction of the second information block overriding the uplink time domain symbol or downlink time domain symbol configured in the first information block.

[0486] As an example, the statement in the claim that "the link direction indication of the target sub-band is used to determine whether the second information block can overwrite the link direction of the uplink time domain symbol or downlink time domain symbol configured in the first information block" includes the following meaning: the link direction indication of the target sub-band is used to explicitly or implicitly indicate whether the second information block can modify the link direction of the uplink time domain symbol or downlink time domain symbol configured in the first information block.

[0487] As an example, the statement in the claim that "the link direction indication of the target sub-band is used to determine whether the second information block can overwrite the link direction of the uplink time domain symbol or downlink time domain symbol configured by the first information block" includes the following meaning: the link direction indication of the target sub-band is used to explicitly or implicitly indicate whether the link mode of a time domain symbol is determined by the second information block or the first information block.

[0488] As an example, when the link direction indication of the target sub-band determines that the second information block can override the link direction of the uplink or downlink time domain symbols configured in the first information block, whether the second information block ultimately overrides the link direction of the uplink or downlink time domain symbols configured in the first information block is indicated by other conditions or signaling; when the link direction indication of the target sub-band determines that the second information block cannot override the link direction of the uplink or downlink time domain symbols configured in the first information block, the second information block ultimately does not override the link direction of the uplink or downlink time domain symbols configured in the first information block.

[0489] As an example, the link direction indication of the target sub-band does not ultimately determine the link direction of the uplink time domain symbol or downlink time domain symbol configured by the second information block overwriting the first information block.

[0490] As an example, when the link direction indication of the target sub-band determines that the second information block can overwrite the uplink time domain symbol or downlink time domain symbol configured in the first information block, the position information of the target sub-band in the frequency domain is used to determine the target link direction from the first link direction or the second link direction; otherwise, the target link mode is the first link direction.

[0491] As an example, when the link direction indication of the target sub-band determines that the second information block can override the link direction of the uplink time domain symbol or downlink time domain symbol configured by the first information block, the position information of the target sub-band in the frequency domain is used to determine whether the second information block overrides the link direction of the uplink time domain symbol or downlink time domain symbol configured by the first information block; otherwise, the second information block only overrides the link direction of the flexible time domain symbol configured by the first information block.

[0492] As an example, the configuration information of the target sub-band is used to determine whether the second information block overwrites the link direction of the uplink time domain symbol or downlink time domain symbol configured in the first information block.
