[0379] Example 3

[0380] 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 communication node device (UE, gNB, or RSU in V2X) and the second communication node device (gNB, UE, or RSU in V2X), or between two UEs, 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 communication node devices and between the two UEs via PHY301. L2 layer 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, which terminate at the second communication node device. The PDCP sublayer 304 provides multiplexing between different radio bearers and logical channels. PDCP sublayer 304 also provides security through encrypted data packets and supports cross-cell mobility between second communication node devices and the first communication node device. RLC sublayer 303 provides upper layer data packet segmentation and reassembly, retransmission of lost data packets, and data 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 between the first communication 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 and first communication 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 communication 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 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, which is responsible for mapping between QoS streams and data radio bearers (DRBs) to support service diversity. Although not illustrated, the first communication node device may have several upper layers above the 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., a remote UE, server, etc.).

[0398] Example 4

[0399] Example 4 shows schematic diagrams of a first communication device and a second communication device according to this application, as shown in the appendix. Figure 4 As shown. Figure 4 This is a block diagram of a first communication device 410 and a second communication device 450 communicating with each other in an access network.

[0400] The first communication device 410 includes a controller / processor 475, a memory 476, a receiver processor 470, a transmitter processor 416, a multi-antenna receiver processor 472, a multi-antenna transmitter processor 471, a transmitter / receiver 418, and an antenna 420.

[0401] The second communication device 450 includes a controller / processor 459, a memory 460, a data source 467, a transmitting processor 468, a receiving processor 456, a multi-antenna transmitting processor 457, a multi-antenna receiving processor 458, a transmitter / receiver 454, and an antenna 452.

[0402] In the transmission from the first communication device 410 to the second communication device 450, at the first communication device 410, upper-layer data packets from the core network are provided to the controller / processor 475. The controller / processor 475 implements L2 layer functionality. In the transmission from the first communication device 410 to the second communication device 450, the controller / processor 475 provides header compression, encryption, packet segmentation and reordering, multiplexing between logical and transport channels, and radio resource allocation to the second communication device 450 based on various priority metrics. The controller / processor 475 is also responsible for retransmitting lost packets and signaling to the second communication device 450. The transmit processor 416 and the multi-antenna transmit processor 471 implement various signal processing functions for the L1 layer (i.e., the physical layer). Transmit processor 416 performs encoding and interleaving to facilitate forward error correction (FEC) at the second communication device 450, and mapping of signal clusters based on various modulation schemes (e.g., Binary Phase Shift Keying (BPSK), Quadrature Phase Shift Keying (QPSK), M-Phase Shift Keying (M-PSK), M-QAM). Multi-antenna transmit processor 471 performs digital spatial precoding on the encoded and modulated symbols, including codebook-based and non-codebook-based precoding, and beamforming processing, generating one or more spatial streams. Transmit processor 416 then maps each spatial stream to subcarriers, multiplexes it with a reference signal (e.g., a pilot) in the time and / or frequency domains, and subsequently uses inverse fast Fourier transform (IFFT) to generate a physical channel carrying the time-domain multicarrier symbol stream. Multi-antenna transmit processor 471 then performs transmit analog precoding / beamforming operations on the time-domain multicarrier symbol stream. Each transmitter 418 converts the baseband multicarrier symbol stream provided by the multi-antenna transmitter processor 471 into an radio frequency stream, which is then provided to different antennas 420.

[0403] In the transmission from the first communication device 410 to the second communication device 450, at the second communication device 450, each receiver 454 receives a signal through its corresponding antenna 452. Each receiver 454 recovers the information modulated onto the radio frequency carrier and converts the radio frequency stream into a baseband multicarrier symbol stream, which is then provided to the receiver processor 456. The receiver processor 456 and the multi-antenna receiver processor 458 implement various signal processing functions of the L1 layer. The multi-antenna receiver processor 458 performs receive analog precoding / beamforming operations on the baseband multicarrier symbol stream from the receiver 454. The receiver processor 456 uses a Fast Fourier Transform (FFT) to convert the baseband multicarrier symbol stream after the receive analog precoding / beamforming operations from the time domain to the frequency domain. In the frequency domain, the physical layer data signal and the reference signal are demultiplexed by the receiver processor 456, where the reference signal is used for channel estimation, and the data signal is recovered in the multi-antenna receiver processor 458 after multi-antenna detection to recover any spatial stream destined for the second communication device 450. Symbols on each spatial stream are demodulated and recovered in the receive processor 456, generating soft decisions. The receive processor 456 then decodes and deinterleaves the soft decisions to recover the upper-layer data and control signals transmitted by the first communication device 410 over the physical channel. The upper-layer data and control signals are then provided to the controller / processor 459. The controller / processor 459 implements the functions of Layer 2. The controller / processor 459 may be associated with a memory 460 storing program code and data. The memory 460 may be referred to as computer-readable media. In the transmission from the first communication device 410 to the second communication device 450, the controller / processor 459 provides multiplexing, packet reassembly, decryption, header decompression, and control signal processing between the transport and logical channels to recover upper-layer data packets from the core network. The upper-layer data packets are then provided to all protocol layers above Layer 2. Various control signals may also be provided to Layer 3 for Layer 3 processing.

[0404] In the transmission from the second communication device 450 to the first communication device 410, at the second communication device 450, a data source 467 is used to provide upper-layer data packets to the controller / processor 459. The data source 467 represents all protocol layers above the L2 layer. Similar to the transmission functions at the first communication device 410 described in the transmission from the first communication device 410 to the second communication device 450, the controller / processor 459 implements header compression, encryption, packet segmentation and reordering, and multiplexing between logical and transport channels based on radio resource allocation, implementing L2 layer functions for the user plane and control plane. The controller / processor 459 is also responsible for retransmitting lost packets and signaling to the first communication device 410. Transmit processor 468 performs modulation mapping and channel coding processing, while multi-antenna transmit processor 457 performs digital multi-antenna spatial precoding, including codebook-based and non-codebook-based precoding, and beamforming processing. Subsequently, transmit processor 468 modulates the generated spatial stream into a multi-carrier / single-carrier symbol stream. After analog precoding / beamforming operations in multi-antenna transmit processor 457, the stream is provided to different antennas 452 via transmitter 454. Each transmitter 454 first converts the baseband symbol stream provided by multi-antenna transmit processor 457 into a radio frequency symbol stream before providing it to antenna 452.

[0405] In the transmission from the second communication device 450 to the first communication device 410, the function at the first communication device 410 is similar to the receiving function at the second communication device 450 described in the transmission from the first communication device 410 to the second communication device 450. Each receiver 418 receives radio frequency signals through its corresponding antenna 420, converts the received radio frequency signals into baseband signals, and provides the baseband signals to the multi-antenna receiving processor 472 and the receiving processor 470. The receiving processor 470 and the multi-antenna receiving processor 472 jointly implement the L1 layer functions. The controller / processor 475 implements the L2 layer functions. The controller / processor 475 may be associated with a memory 476 that stores program code and data. The memory 476 may be referred to as computer-readable media. In the transmission from the second communication device 450 to the first communication device 410, the controller / processor 475 provides multiplexing between the transmission and logical channels, packet reassembly, decryption, header decompression, and control signal processing to recover upper-layer data packets from the UE 450. Upper-layer packets from the controller / processor 475 can be provided to the core network.

(See Appendix) Figure 7 In this context, the first time-domain resource pool set includes a total of 5 time-domain resource pools. Among these 5 time-domain resource pools, 3 time-domain resource pools belong to the feature time-domain resource pool subset, and these 5 time-domain resource pools are divided into 4 time-domain resource pool subsets (represented by dashed boxes).

[0498] In Embodiment 7, the third value in this application is greater than the reference value in this application; the third value is used to determine multiple time-domain resource pool subsets from the first time-domain resource pool set, each of the multiple time-domain resource pool subsets includes at least one time-domain resource pool in the first time-domain resource pool set, and the first value in this application is equal to the number of time-domain resource pool subsets in the multiple time-domain resource pool subsets that include at least one time-domain resource pool belonging to the feature time-domain resource pool subset.

[0519] Example 9

[0520] Example 9 illustrates a schematic diagram of the relationship between first information according to an embodiment of this application, a given temporal resource pool, and a subset of characteristic temporal resource pools, as shown in the attached diagram. Figure 9 As shown.

[0521] In Embodiment 9, the first information is used to determine the type of time-domain symbol; when a given time-domain resource pool in the first time-domain resource pool set overlaps with at least one time-domain symbol of the type of uplink symbol, the given time-domain resource pool does not belong to the feature time-domain resource pool subset.

[0522] As an example, the first information is used to indicate the type of time-domain symbol.

[0523] As an example, the first information is used to explicitly indicate the type of time-domain symbol.

[0524] As one embodiment, the first information is used to indicate the type of each time-domain symbol included in at least a first time window, the first time window including all time-domain resources occupied by at least the first time-domain resource pool set.

[0525] As an example, the first information is used to determine the type of time-domain symbols included in each resource pool of the first time-domain resource pool set.

[0526] As an example, the first information is used to determine the type of time-domain symbol that overlaps with any resource pool in the first time-domain resource pool set.

[0527] As an example, the first information is used to indicate the type of time-domain symbols included in each resource pool of the first time-domain resource pool set.

[0528] As an example, the first information is used to indicate the type of time domain symbol that overlaps with any resource pool in the first time domain resource pool set.

[0529] As an example, the given time-domain resource pool is any time-domain resource pool in the first set of time-domain resource pools.

[0530] As an example, the type of a time-domain symbol can be configured as one of {uplink symbol, downlink symbol}.

[0531] As an example, the type of a time-domain symbol can be configured as one of {uplink symbol, downlink symbol, flexible symbol}.

[0532] As an example, no time-domain resource pool in the feature time-domain resource pool subset overlaps with any time-domain symbol of the type uplink symbol.

[0533] As an example, when a given time-domain resource pool in the first time-domain resource pool set does not overlap with any time-domain symbol of the type uplink symbol, the given time-domain resource pool belongs to the subset of the characteristic time-domain resource pools.

[0534] As an example, the first information is used to determine the type of time-domain symbols; for a given time-domain resource pool in the first time-domain resource pool set, the type of the time-domain symbols included in the given time-domain resource pool is used to determine whether the given time-domain resource pool belongs to the feature time-domain resource pool subset.

[0535] As an example, the first information is used to determine the type of time-domain symbol; when a given time-domain resource pool in the first time-domain resource pool set includes at least one time-domain symbol of the type of uplink symbol, the given time-domain resource pool does not belong to the feature time-domain resource pool subset.

[0536] As an example, when a given time-domain resource pool in the first time-domain resource pool set does not include any time-domain symbols of the type uplink symbol, the given time-domain resource pool belongs to the subset of the characteristic time-domain resource pools.

[0537] As an example, none of the time-domain resource pools in the subset of the characteristic time-domain resource pools include time-domain symbols of the type uplink symbol.

[0540] Example 10

[0541] Example 10 illustrates a schematic diagram showing the relationship between the value of the first DAI field, the second value, the target number of bits, and the first transmit power in a first signaling according to an embodiment of this application, as shown in the attached diagram. Figure 10 As shown.

[0542] In Example 10, the target number of bits is used to determine the first transmit power, the second value is used to determine the target number of bits, and the value of the first DAI field in the first signaling is used to determine the second value.

[0543] As an example, the target number of bits is linearly related to the second value.

[0544] As an example, the target number of bits is equal to the sum of multiple values, and the second value is one of the multiple values.

[0545] As an example, the value of the first DAI field in the first signaling is used to determine that the second value is equal to 0.

[0546] As an example, the second value is equal to the first intermediate quantity multiplied by the fifth value, and the first intermediate quantity is equal to the difference between the value of the first DAI field in the first signaling and the first total quantity, modulo the fourth value.

[0547] As an example, the fifth value is a positive integer.

[0548] As an example, the fifth value is configurable.

[0549] As an example, the fifth value is determined based on the configuration of higher-layer signaling.

[0550] As an example, the fifth value is associated with the third value.

[0551] As an example, the third value is used to determine the fifth value.

[0552] As an example, when the third value is not greater than the reference value, the fifth value is equal to 1.

[0553] As an example, when the third value is not greater than the reference value, the fifth value is equal to 1 or 2.

[0554] As an example, when the third value is not greater than the reference value: if the value of the maxNrofCodeWordsScheduledByDCI parameter for any serving cell is 2 and harq-ACK-SpatialBundlingPUCCH is not configured, then the fifth value is equal to 2; otherwise, the fifth value is equal to 1.

[0555] As an example, when the third value is greater than the reference value, the fifth value is the maximum value in the first set of values, the first set of values ​​includes at least one value, and the values ​​in the first set of values ​​are all configurable.

[0556] As an example, each value in the first set of values ​​is for a serving cell.

[0557] As an example, one of the values ​​in the first set of values ​​is configured by higher-level signaling.

[0558] As an example, one of the values ​​in the first set of values ​​is configured by RRC signaling.

[0559] As an example, one of the values ​​in the first set of values ​​is configured by MAC CE signaling.

[0560] As an example, the fourth value is a positive integer.

[0561] As an example, the fourth value is a positive integer greater than 1.

[0562] As an example, the fourth value is equal to 2 raised to the power of V, where V is equal to the number of bits included in a counterDAI field.

[0563] As an example, the fourth value is equal to 2 raised to the power of V, where V is equal to the number of bits included in the first field of the first signaling.

[0564] As an example, the fourth value is equal to 2 raised to the power of V, where V is equal to the number of bits included in the count DAI field in the first signaling.

[0565] As an example, the first total is the cumulative number in DCI format.

[0566] As an example, the first total is the total number of DCI formats detected that are associated with at least one HARQ-ACK bit carried by the first PUCCH.

[0567] As an example, the first total number is the total number of DCI formats detected as associated with HARQ-ACK bits in the target HARQ-ACK subcodebook, which is the HARQ-ACK subcodebook that includes the HARQ-ACK bits associated with the first signaling.

[0568] As an example, in this application, a DCI format associated with a HARQ-ACK bit means that the HARQ-ACK bit is used to indicate whether at least one bit block in at least one PDSCH scheduled by the DCI format has been correctly decoded, or the HARQ-ACK bit is used to indicate that the DCI format has been detected.

[0569] As an example, in this application, a DCI format associated with a HARQ-ACK bit means that the HARQ-ACK bit is for at least one PDSCH reception scheduled by the DCI format, or that the HARQ-ACK bit is for the DCI format and the DCI format is not used to schedule PDSCH reception.

[0570] As an example, the first total number is a positive integer.

[0571] As an example, the second value is equal to 0.

[0572] As an example, the calculated result of the second value is equal to 0.

[0573] As an example, the calculation result of the first intermediate quantity is equal to 0.
