[0082] As an example, the ConfiguredGrantConfig IE is used to configure the configured grant PUSCH transmission, and the higher layer parameter repK-RV in the ConfiguredGrantConfig IE indicates the RV (redundancy version) sequence.

[0101] As an example, rate matching includes bit selection, different RVs correspond to different starting positions of bit selection, and the relationship between the RV and the corresponding starting position is defined in Table 5.4.2.1-2 of 3GPP TS 38.212.

[0102] As an example, in this application, an RV refers to rv id , where the rv id is an element in the set {0, 2, 3, 1}.

[0103] As an example, an RV is the redundancy version number for a single transmission of a transport block.

[0104] As an example, the multiple transmission opportunities are transmission occasions for multiple repetitions of a transport block.

[0105] As an example, the multiple transmission opportunities are reserved for the transmission of a configured grant PUSCH.

[0106] As an example, each of the multiple transmission opportunities is defined by frequency-domain resources and time-domain resources.

[0118] As an example, the first transmission starts at one of the multiple transmission opportunities, and the terminal starts to perform multiple transmissions of a transport block from this transmission opportunity.

[0119] As an example, if the higher layer parameter startingFromRV0 in the ConfiguredGrantConfig IE is set to 'off', then the transmission opportunity where the first transmission starts is the first transmission opportunity among the multiple transmission opportunities.

[0120] As an example, in the present application, the higher layer parameter cg-RetransmissionTimer is not provided in the ConfiguredGrantConfig IE.

[0121] As an example, in the present application, the higher layer parameter startingFromRV0 is provided in the ConfiguredGrantConfig IE.

[0122] As an example, in the present application, the higher layer parameter startingFromRV0 in the ConfiguredGrantConfig IE is set to 'on'.

[0192] As an example, the first type of transmission opportunity depends on the first configuration, including: the result of taking the remainder of the sorting index corresponding to the first type of transmission opportunity with respect to M is 0; the first configuration includes the configuration of whether the first transmission applies the orthogonal sequence of PUSCH; the first transmission does not apply the orthogonal sequence of PUSCH, and M is equal to 1.

[0193] As an example, the sorting indexes corresponding to the multiple transmission opportunities are non-negative integers.

[0194] As an example, the sorting index corresponding to the first transmission opportunity among the multiple transmission opportunities is 0.

[0195] As an example, the multiple transmission opportunities are arranged in sequence in the time domain, and the sorting indexes corresponding to the multiple transmission opportunities start from 0.

[0196] As an example, the first type of transmission opportunity depends on the first configuration, including: all the first type of transmission opportunities are the transmission opportunities among the multiple transmission opportunities associated with RV = 0, and the RV associated with each transmission opportunity among the multiple transmission opportunities depends on the first configuration.

[0197] As an example, the first type of transmission opportunity depends on the first configuration, including: the first transmission applies the orthogonal sequence of PUSCH; all the first type of transmission opportunities are the transmission opportunities among the multiple transmission opportunities associated with RV = 0, and the RV associated with each transmission opportunity among the multiple transmission opportunities depends on the length of the orthogonal sequence of PUSCH indicated by the first configuration.

[0198] As an example, among the multiple transmission opportunities, the transmission opportunity corresponding to the sorting index n is associated with the i-th RV in the first RV sequence, where i is the result of adding 1 after taking the remainder of the first intermediate value divided by 4; wherein, the first intermediate value is the ratio of the result of subtracting the second intermediate value from n to M, and the second intermediate value is the result of taking the remainder of n divided by M; the first transmission applies the orthogonal sequence of PUSCH, and M is the length of the orthogonal sequence of PUSCH indicated by the first configuration.

[0199] As an example, the transmission opportunity where the first transmission starts depends on the RV configuration and the first configuration, including: the first configuration includes the configuration of whether the first transmission applies the orthogonal sequence of PUSCH; if the first configuration indicates that the first transmission does not apply the orthogonal sequence of PUSCH: the transmission opportunity where the first transmission starts depends on the RV sequence configuration; if the first configuration indicates that the first transmission applies the orthogonal sequence of PUSCH: the transmission opportunity where the first transmission starts depends on the RV sequence configuration and the length of the orthogonal sequence of PUSCH indicated by the first configuration.

[0205] As an example, the advantages of the above method include: having little impact on terminals that do not support the orthogonal sequence of PUSCH.

[0206] As an example, the transmission opportunity where the first transmission starts depends on the RV configuration and the first configuration, including: the first configuration includes the configuration of whether the first transmission applies the orthogonal sequence of PUSCH; if the first configuration indicates that the first transmission applies the orthogonal sequence of PUSCH:

[0208] When the first RV sequence is configured as one of the RV sequences in the first candidate RV sequence set, the transmission opportunity where the first transmission starts is one of the first - type transmission opportunities among the multiple transmission opportunities.

[0210] As an example, the transmission opportunity where the first transmission starts depends on the RV configuration and the first configuration, including: the first configuration includes the configuration of whether the first transmission applies the orthogonal sequence of PUSCH; if the first configuration indicates that the first transmission applies the orthogonal sequence of PUSCH:

[0211] When the first RV sequence is configured as {0, 2, 3, 1}, the transmission opportunity where the first transmission starts is the first transmission opportunity among the multiple transmission opportunities;

[0212] When the first RV sequence is configured as {0, 3, 0, 3} or {0, 0, 0, 0}, the transmission opportunity where the first transmission starts is a transmission opportunity among the multiple transmission opportunities that is associated with RV = 0 and the corresponding sorting index modulo M results in 0.

[0213] As an example, the benefits of the above method include: small changes to the standard.

[0214] As an example, the first type of transmission opportunity is a subset of the multiple transmission opportunities.

[0215] As an example, when the first RV sequence is an RV sequence in the first candidate RV sequence set, the transmission opportunity where the first transmission starts is a first type of transmission opportunity among the multiple transmission opportunities; which transmission opportunity in the first type of transmission opportunities the transmission opportunity where the first transmission starts is is implemented by the terminal.

Figure 3 is a schematic diagram illustrating an embodiment of a radio protocol architecture for a user plane 350 and a control plane 300. Figure 3The radio protocol architecture for controlling plane 300 is shown with three layers: Layer 1 (L1), Layer 2 (L2), and Layer 3 (L3). L1 is the lowest layer and implements various PHY (Physical Layer) signal processing functions. L1 will be referred to as PHY301 in this text. Layer 2 (L2 layer) 305 is above PHY301 and is responsible for the link between the first communication node device and the second communication node device as well as between two UEs through PHY301. L2 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. 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. 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 disordered reception due to HARQ (Hybrid Automatic Repeat Request).

[0239] Example 4

[0240] Embodiment 4 shows a schematic diagram of a first communication device and a second communication device according to this application, as shown in the Figure 4 figure. Figure 4 It is a block diagram of a first communication device 410 and a second communication device 450 that communicate with each other in an access network.

[0241] The first communication device 410 includes a controller / processor 475, a memory 476, a receiving processor 470, a transmitting processor 416, a multi-antenna receiving processor 472, a multi-antenna transmitting processor 471, a transmitter / receiver 418, and an antenna 420.

[0242] 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.

[0243] 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 the functionality of the L2 layer. 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 for the second communication device 450 based on various priority metrics. The controller / processor 475 is also responsible for retransmission of 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). The transmit processor 416 implements encoding and interleaving to facilitate forward error correction (FEC) at the second communication device 450, and mapping of signal constellations based on various modulation schemes (e.g., Binary Phase Shift Keying (BPSK), Quadrature Phase Shift Keying (QPSK), M-Phase Shift Keying (M-PSK), M-Quadrature Amplitude Modulation (M-QAM)). The multi-antenna transmit processor 471 performs digital spatial precoding on the encoded and modulated symbols, including codebook-based precoding and non-codebook-based precoding, and beamforming processing, to generate one or more spatial streams. The transmit processor 416 then maps each spatial stream to subcarriers, multiplexes with reference signals (e.g., pilots) in the time domain and / or frequency domain, and then uses the Inverse Fast Fourier Transform (IFFT) to generate a physical channel carrying time-domain multi-carrier symbol streams. Subsequently, the multi-antenna transmit processor 471 performs transmit analog precoding / beamforming operations on the time-domain multi-carrier symbol streams. Each transmitter 418 converts the baseband multi-carrier symbol streams provided by the multi-antenna transmit processor 471 into radio frequency streams and then provides them to different antennas 420.

[0244] 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 signals via its respective antenna 452. Each receiver 454 recovers the information modulated onto the radio frequency carrier and converts the radio frequency stream into a baseband multi-carrier symbol stream that is provided to the receive processor 456. The receive processor 456 and the multi-antenna receive processor 458 perform various signal processing functions of the L1 layer. The multi-antenna receive processor 458 performs receive analog precoding / beamforming operations on the baseband multi-carrier symbol stream from the receivers 454. The receive processor 456 uses the Fast Fourier Transform (FFT) to convert the baseband multi-carrier 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 receive processor 456, where the reference signal will be used for channel estimation, and the data signal recovers any spatial streams destined for the second communication device 450 after multi-antenna detection in the multi-antenna receive processor 458. The symbols on each spatial stream are demodulated and recovered in the receive processor 456, and soft decisions are generated. Subsequently, the receive processor 456 decodes and de-interleaves the soft decisions to recover the upper layer data and control signals transmitted by the first communication device 410 on the physical channel. Subsequently, the upper layer data and control signals are provided to the controller / processor 459. The controller / processor 459 performs the functions of the L2 layer. The controller / processor 459 may be associated with a memory 460 that stores program code and data. The memory 460 may be referred to as a computer-readable medium. In the transmission from the first communication device 410 to the second communication device 450, the controller / processor 459 provides demultiplexing between transport and logical channels, packet reassembly, decryption, header decompression, control signal processing to recover upper layer data packets from the core network. Subsequently, the upper layer data packets are provided to all protocol layers above the L2 layer. Various control signals may also be provided to the L3 for L3 processing.

[0245] 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 an upper layer data packet to a controller / processor 459. The data source 467 represents all protocol layers above the L2 layer. Similar to the transmit function described at the first communication device 410 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, and implements L2 layer functions for both the user plane and the control plane. The controller / processor 459 is also responsible for retransmission of lost packets and signaling to the first communication device 410. A transmit processor 468 performs modulation mapping and channel coding processing, and a multi-antenna transmit processor 457 performs digital multi-antenna spatial precoding, including codebook-based precoding and non-codebook-based precoding, and beamforming processing. Subsequently, the transmit processor 468 modulates the generated spatial streams into a multi-carrier / single-carrier symbol stream, which is provided to different antennas 452 via a transmitter 454 after an analog precoding / beamforming operation in the multi-antenna transmit processor 457. Each transmitter 454 first converts the baseband symbol stream provided by the multi-antenna transmit processor 457 into a radio frequency symbol stream and then provides it to the antenna 452.

[0246] In the transmission from the second communication device 450 to the first communication device 410, the functions at the first communication device 410 are similar to the receive function described at the second communication device 450 in the transmission from the first communication device 410 to the second communication device 450. Each receiver 418 receives a radio frequency signal through its corresponding antenna 420, converts the received radio frequency signal into a baseband signal, and provides the baseband signal to a multi-antenna receive processor 472 and a receive processor 470. The receive processor 470 and the multi-antenna receive processor 472 jointly implement the functions of the L1 layer. A 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 a computer-readable medium. In the transmission from the second communication device 450 to the first communication device 410, the controller / processor 475 provides demultiplexing between transport and logical channels, packet reassembly, decryption, header decompression, and control signal processing to recover the upper layer data packet from the UE 450. The upper layer data packet from the controller / processor 475 may be provided to the core network.
