Description

Technical Field

[0001] This application relates to transmission methods and apparatus in wireless communication systems, and more particularly to transmission schemes and apparatus for information with different priority levels 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 WI (Work Item) for NR, 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 NR Rel-17.

[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 URLLC communication, data or control information with different priority levels can be transmitted. In NR Rel-16, when UCIs (Uplink Control Information) with different priority levels collide in the time domain, the lower-priority UCI is abandoned to ensure the transmission of the higher-priority UCI. In NR Rel-17, multiplexing UCIs with different priority levels onto the same PUCCH or the same PUSCH is supported.

[0005] This application discloses a solution to the problem of UCI multiplexing associated with different priority levels. It should be noted that URLLC is only used as a typical application scenario or example in the description of this application; this application is also applicable to other scenarios facing similar problems (such as scenarios with multiple services coexisting, or other scenarios with multiplexing of information with different priority levels, or scenarios with multiplexing of services with different QoS requirements, or for different application scenarios, such as vehicle-to-everything (V2X) and eMBB multiplexing), and can achieve similar technical effects. Furthermore, adopting a unified solution for different scenarios (including but not limited to URLLC scenarios) 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 interpretation of terms, nouns, functions, and variables in this application (unless otherwise specified) can be found in 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] Receive a first signaling and a first signal, the first signaling being used to schedule a first PUSCH, the first PUCCH being associated with the first signal, and the first PUSCH and the first PUCCH having overlapping time-domain resources.

[0008] Determine a second signal and send the second signal, the second signal being one of the first PUSCH or the first PUCCH, the second signal carrying HARQ-ACK bits for the first signal;

[0009] Wherein, the first signaling carries a first DAI, the value of which is a non-negative integer; the priority level index of the first signal is equal to the first level index value, which is a non-negative integer; the first signaling is used to determine a second level index value, which is a non-negative integer; the first level index value and the second level index value are not equal; the value of the first DAI is equal to one of X1 candidate values, where X1 is a positive integer greater than 1; any one of the X1 candidate values ​​is a non-negative integer; and the first reference value is one of the X1 candidate values; whether the first level index value, or at least one of the second level index values, and the value of the first DAI are equal to the first reference value are used together to determine the second signal.

[0010] As an example, the value of the uplink DAI is combined with the priority information to determine whether to multiplex UCIs of different priority levels and / or to determine the multiplexing method. In this way, while ensuring the performance of high-priority UCIs, low-priority UCIs are reused as much as possible, thereby improving the performance and capacity of UCIs, especially HARQ-ACK bits.

[0012] As an example, when transmitting HARQ-ACK with uplink DAI indicating backoff (i.e., only a limited number of HARQ-ACK bits can be transmitted), the transmission method of HARQ-ACK is determined by comparing the priority relationship between PUCCH and PUSCH, thus ensuring the performance of high-priority HARQ-ACK while reusing low-priority HARQ-ACK as much as possible.

[0020] As an example, by determining the number of multiplexed HARQ-ACK bits, it is further determined whether and how to multiplex them, thereby further ensuring the performance of high-priority HARQ-ACK transmission.

As shown in the figure, 5GS / EPS provides packet-switched services; however, those skilled in the art will readily understand that the various concepts presented throughout this application can be extended to networks providing circuit-switched services or other cellular networks. NG-RAN includes NR / Evolved Node B (gNB / eNB) 203 and other gNBs (eNBs) 204. gNBs (eNBs) 203 provide user and control plane protocol termination to UE 201. gNBs (eNBs) 203 can connect to other gNBs (eNBs) 204 via Xn / X2 interfaces (e.g., backhaul). gNBs (eNBs) 203 may also be referred to as a base station, base transceiver station, radio base station, radio transceiver, transceiver function, Basic Services Set (BSS), Extended Services Set (ESS), TRP (Transmitter Receiver Node), or some other suitable terminology. gNBs (eNBs) 203 provide UE 201 with an access point to the 5GC / EPC 210.

[0233] Example 3

[0234] 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.).

[0243] Example 4

[0244] 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.

[0245] 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.

[0246] 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.

[0247] In the DL (Downlink), upper-layer packets, such as the upper-layer information carried by the first signal in this application (when the first signal includes upper-layer information), are provided to the controller / processor 440. The controller / processor 440 implements functions at Layer 2 and above. 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 operation, retransmission of lost packets, and signaling to the first node device 450, such as the higher-layer information included in the first signal in this application, which is generated in the controller / processor 440. The transmit processor 415 implements various signal processing functions for Layer 1 (i.e., physical layer), including coding, interleaving, scrambling, modulation, power control / allocation, precoding, and physical layer control signaling generation, such as the generation of the first and second signaling in this application, as well as the physical layer signal carrying the first signal, which is 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 functions include receiving the physical layer signal carrying the first signal and the first and second signaling in this application; demodulating the multicarrier symbols in the multicarrier symbol stream based on various modulation schemes (e.g., Binary Phase Shift Keying (BPSK), Quadrature Phase Shift Keying (QPSK)); subsequently 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. The controller / processor 490 interprets the higher-level information included in the first signal in this application (when the first signal includes upper-level information). 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.

[0248] In uplink (UL) transmission, similar to downlink transmission, the higher-layer information, including the higher-layer information carried by the first PUSCH 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 determination of the first PUSCH and the second signal in this application are generated by the transmitter processor 455. Then, the physical layer signal of the second signal is mapped by the transmitter processor 455 to the antenna 460 via the transmitter 456 and transmitted as a radio frequency signal. The receiver 416 receives the radio frequency signal through its corresponding antenna 420.

[0467] Example 13

[0468] Example 13 illustrates a structural block diagram of a processing device in a first node device according to an embodiment, as shown in the attached diagram. Figure 13 As shown. In the appendix Figure 13 In the first node device processing unit 1300, there are a first receiver 1301 and a first transmitter 1302. The first receiver 1301 includes the components specified in the appendix of this application. Figure 4 The transmitter / receiver 456 (including antenna 460), receiver processor 452, and controller / processor 490 are included; the first transmitter 1302 includes the appendix to this application. Figure 4 The transmitter / receiver 456 (including antenna 460), the transmitter processor 455, and the controller / processor 490 are included.

[0469] In embodiment 13, a first receiver 1301 receives a first signaling and a first signal. The first signaling is used to schedule a first PUSCH. The first PUSCH is associated with the first signal, and the first PUSCH and the first PUCCH have overlapping time-domain resources. A first transmitter 1302 determines a second signal and transmits the second signal. The second signal is either the first PUSCH or the first PUCCH. The second signal carries HARQ-ACK bits for the first signal. The first signaling carries a first DAI, the value of which is a non-negative integer. The priority level of the first signal is... The index value is equal to the first-level index value, which is a non-negative integer. The first signaling is used to determine the second-level index value, which is also a non-negative integer. The first-level index value and the second-level index value are not equal. The first DAI value is equal to one of X1 candidate values, where X1 is a positive integer greater than 1, and any one of the X1 candidate values ​​is a non-negative integer. The first reference value is one of the X1 candidate values. Whether the first-level index value, or at least one of the second-level index values, and the first DAI value are equal to the first reference value are used together to determine the second signal.

[0470] As an example, when the value of the first DAI is equal to one of the X1 candidate values ​​other than the first reference value, the second signal is the first PUSCH; when the value of the first DAI is equal to the first reference value, the magnitude relationship between the first level index value and the second level index value is used to determine the second signal from the first PUSCH or the first PUCCH.

[0471] As an example, the HARQ-ACK bit for the first signal belongs to a first HARQ codebook, which includes at least one HARQ-ACK bit; the first HARQ codebook, which includes only the HARQ-ACK bit for the first signal, is used to determine that the second signal carries the HARQ-ACK bit for the first signal.

[0472] As an example, the first signaling carries a first offset indication, the value of which is equal to one of X2 candidate values, where X2 is a positive integer greater than 1, and a second reference value is one of the X2 candidate values; the value of the first offset indication equal to the second reference value is used to determine that the second signal carries HARQ-ACK bits for the first signal.

[0473] As an example, the first receiver 1301 receives a second signaling; wherein the second signaling is used to schedule the first signal, the second signaling and the time-domain resources occupied by the first signal are used to determine the time-domain resources of the first PUCCH, the second signaling is used to determine the first level index value; the second signaling carries a second DAI, the value of the second DAI being a non-negative integer; the value of the second DAI is used to determine that the second signal carries HARQ-ACK bits for the first signal.

[0474] As an example, when the first level index value is greater than the second level index value and the value of the first DAI is equal to the first reference value, the number of bits included in the HARQ codebook to which the HARQ-ACK bit of the first signal belongs is equal to the target number, which is a positive integer; the relationship between the target number and the first threshold is used to determine the second signal from the first PUSCH or the first PUCCH; the first threshold is a non-negative integer.

[0475] As an example, the number of symbols that the first signal and the first PUSCH are separated by in the time domain is equal to a first number, and the number of symbols that the first signaling and the first signal are separated by in the time domain is equal to a second number. At least one of the first number or the second number is used to determine the second signal from the first PUSCH or the first PUCCH.

Figure 4 The transmitter / receiver 416 (including antenna 460), the transmitter processor 415, and the controller / processor 440 are included; the second receiver 1402 includes the appendix to this application. Figure 4 The transmitter / receiver 416 (including antenna 460), receiver processor 412, and controller / processor 440 are included.

[0478] In embodiment 14, the second transmitter 1401 transmits a first signaling and a first signal. The first signaling is used to schedule a first PUSCH, which is associated with the first PUCCH. The first PUSCH and the first PUCCH have overlapping time-domain resources. The second receiver 1402 receives a second signal, which is either the first PUSCH or the first PUCCH. The second signal carries HARQ-ACK bits for the first signal. The first signaling carries a first DAI, the value of which is a non-negative integer. The priority index of the first signal, etc. The first level index value is a non-negative integer. The first signaling is used to indicate the second level index value, which is also a non-negative integer. The first level index value and the second level index value are not equal. The value of the first DAI is equal to one of X1 candidate values, where X1 is a positive integer greater than 1, and any one of the X1 candidate values ​​is a non-negative integer. The first reference value is one of the X1 candidate values. Whether the value of the first level index value, or at least one of the second level index values, and the value of the first DAI are equal to the first reference value are used together to determine the second signal.

[0479] As an example, when the value of the first DAI is equal to one of the X1 candidate values ​​other than the first reference value, the second signal is the first PUSCH; when the value of the first DAI is equal to the first reference value, the magnitude relationship between the first level index value and the second level index value is used to determine the second signal from the first PUSCH or the first PUCCH.

[0480] As an example, the HARQ-ACK bit for the first signal belongs to a first HARQ codebook, which includes at least one HARQ-ACK bit; the first HARQ codebook, which includes only the HARQ-ACK bit for the first signal, is used to determine that the second signal carries the HARQ-ACK bit for the first signal.

[0481] As an example, the first signaling carries a first offset indication, the value of which is equal to one of X2 candidate values, where X2 is a positive integer greater than 1, and a second reference value is one of the X2 candidate values; the value of the first offset indication equal to the second reference value is used to determine that the second signal carries HARQ-ACK bits for the first signal.

[0482] As an example, the second transmitter 1401 sends a second signaling; wherein the second signaling is used to schedule the first signal, the second signaling and the time-domain resources occupied by the first signal are used to determine the time-domain resources of the first PUCCH, the second signaling is used to indicate the first level index value; the second signaling carries a second DAI, the value of the second DAI being a non-negative integer; the value of the second DAI is used to determine that the second signal carries HARQ-ACK bits for the first signal.

[0483] As an example, when the first level index value is greater than the second level index value and the value of the first DAI is equal to the first reference value, the number of bits included in the HARQ codebook to which the HARQ-ACK bit of the first signal belongs is equal to the target number, which is a positive integer; the relationship between the target number and the first threshold is used to determine the second signal from the first PUSCH or the first PUCCH; the first threshold is a non-negative integer.

[0484] As an example, the number of symbols that the first signal and the first PUSCH are separated by in the time domain is equal to a first number, and the number of symbols that the first signaling and the first signal are separated by in the time domain is equal to a second number. At least one of the first number or the second number is used to determine the second signal from the first PUSCH or the first PUCCH.
