[0144] As an embodiment, the first PRACH opportunity group is configured to be associated with each other for sending the same Random Access Preamble.

[0145] As an embodiment, the advantages of the above method include: being conducive to improving the transmission performance of random access preambles.

[0146] As an embodiment, the first node transmits the same random access preamble in each of the multiple PRACH opportunities in the first PRACH opportunity group.

[0147] As an embodiment, the same random access preamble is mapped to the physical resources occupied by each of the at least 1 PRACH opportunities in the first PRACH opportunity group and then transmitted.

[0148] As an embodiment, the same random access preamble is mapped to the physical resources occupied by each of the multiple PRACH opportunities in the first PRACH opportunity group and then transmitted.

[0149] As an embodiment, the same random access preamble is repeatedly transmitted multiple times in multiple PRACH (Physical random access channel) opportunities in the first PRACH opportunity group.

[0150] As an embodiment, the PRACH transmitted in the first PRACH opportunity group is associated with a RAR uplink grant.

[0151] As an embodiment, the random access preamble transmitted in any PRACH opportunity in the first PRACH opportunity group is associated with the same RAR uplink grant.

[0152] As a sub - embodiment of the above embodiment, the first PUSCH is the PUSCH scheduled by the same RAR uplink grant, or the Msg3PUSCH re - transmitted for the same RAR uplink grant.

[0153] As a sub - embodiment of the above embodiment, the random access preamble transmitted in any PRACH opportunity in the first PRACH opportunity group is the same random access preamble, and the acquisition of the same RAR uplink grant is based on the response to the same random access preamble.

[0154] As an embodiment, the expression "transmitting a random access preamble in at least 1 PRACH opportunity in the first PRACH opportunity group" means: transmitting multiple signals respectively in multiple PRACH opportunities in the first PRACH opportunity group, and the multiple signals are all generated based on the same random access preamble.

[0155] As an example, the statement "transmitting a random access preamble in at least 1 PRACH opportunity in the first PRACH opportunity group" means: transmitting multiple repetitions of one PRACH respectively in multiple PRACH opportunities in the first PRACH opportunity group, and the multiple repetitions of the one PRACH are all based on the same random access preamble.

[0156] As an example, the first signaling is the signaling for scheduling Msg3 PUSCH.

[0157] As an example, the first signaling is detected in a common search space.

[0158] As an example, the first signaling is DCI (Downlink control information) format 0_0 with CRC (Cyclic redundancy check) scrambled by TC-RNTI (DCI format 0_0 with CRC scrambled by TC-RNTI).

[0159] As an example, the characteristics of the above method include: being applicable to Msg3 PUSCH retransmission(s).

[0160] As an example, the first signaling is a RAR (random access response) UL (Uplink) grant.

[0161] As an example, the characteristics of the above method include: being applicable to PUSCH transmissions scheduled by the RAR UL grant.

[0162] As an example, the random access preamble transmitted in any PRACH opportunity in the first PRACH opportunity group is associated with the first signaling.

[0163] As an example, the first signaling is a RAR UL grant; receiving the first signaling means:

[0164] Receive a transport block in a PDSCH (Physical downlink shared channel); the first node delivers the transport block to higher layers, and the higher layers resolve the transport block for a RAPID (random access preamble identity) associated with a PRACH transmission; the higher layer identifies the RAPID in a RAR message of the transport block and indicates the first signaling to the physical layer.

[0165] As an example, the expression "transmit the first PUSCH" means: transmit a transport block in the first PUSCH.

[0166] As an example, the expression "transmit the first PUSCH" means: transmit information via the first PUSCH.

[0167] As an example, the first PUSCH is a Msg3PUSCH (Physical uplink shared channel).

[0168] As an example, the first PUSCH is the Msg3PUSCH transmitted for the first time.

[0169] As an example, the first PUSCH is the retransmitted Msg3PUSCH.

[0170] As an example, the expression "the first PUSCH occupies the target frequency-domain resource allocation in the frequency domain" means: in terms of the frequency domain, the target frequency-domain resource allocation is allocated to the first PUSCH.

[0171] As an example, the target frequency-domain resource allocation is allocated to the first PUSCH according to the second type of uplink resource allocation (Uplink resource allocation type 2) strategy, and see Section 6.1.2.2.3 of 3GPP TS 38.214 for the second type of uplink resource allocation strategy.

[0172] As an example, in terms of the frequency domain, the first PUSCH includes each RB (Resource block) in the target frequency-domain resource allocation.

[0173] As an example, the statement "the first signaling and the target RB set are used together to determine the target frequency-domain resource allocation" means that the target frequency-domain resource allocation is determined as the intersection of the resource blocks (RBs) of the interlace(s) indicated by the first signaling and the target RB set.

[0174] As an example, the first signaling indicates at least one interlace, and the target frequency-domain resource allocation is composed of the resource blocks in the target RB set that belong to the at least one interlace.

[0175] As an example, the target frequency-domain resource allocation includes consecutive RBs; the number of RBs included in the target frequency-domain resource allocation is equal to the result of taking the modulus of 259 of the difference between the number of bits included in the first signaling and the cube of the cardinality of the target RB set; the index of the first RB in the target frequency-domain resource allocation is equal to the result of taking the modulus of 17 of the sum of the square of the number of bits with a value of 1 included in the first signaling, the number of user equipments that the first node has detected around and has established connections with the sender of the first signaling, and the total number of DCI formats of scheduled PUSCH received before the first signaling.

[0176] As an example, that a PRACH opportunity occupies an RB set means that, from the perspective of the frequency domain, this PRACH opportunity is within this RB set.

[0177] As an example, when each RB included in a PRACH opportunity in the frequency domain is within an RB set, this RB set is the RB set occupied by this PRACH opportunity; when at least one RB included in a PRACH opportunity in the frequency domain is not within an RB set, this RB set is not the RB set occupied by this PRACH opportunity.

[0178] As an example, when at least one RB included in a PRACH opportunity in the frequency domain is within an RB set, this RB set is the RB set occupied by this PRACH opportunity; when each RB included in a PRACH opportunity in the frequency domain is not within an RB set, this RB set is not the RB set occupied by this PRACH opportunity.

[0179] As an example, each PRACH opportunity in the multiple PRACH opportunities in the first PRACH opportunity group occupies at least one RB set.

[0180] As an example, each PRACH opportunity in the multiple PRACH opportunities in the first PRACH opportunity group occupies only one RB set.

[0181] As an embodiment, there are at least two PRACH opportunities in the first PRACH opportunity group that respectively occupy different RB sets.

[0182] As an embodiment, there are two PRACH opportunities in the first PRACH opportunity group that occupy the same RB set.

[0183] As an embodiment, there are no two PRACH opportunities in the first PRACH opportunity group that occupy the same RB set.

[0184] As an embodiment, there are at least two PRACH opportunities among the multiple PRACH opportunities in the first PRACH opportunity group that respectively occupy different RB sets.

[0185] As an embodiment, there are two PRACH opportunities among the multiple PRACH opportunities in the first PRACH opportunity group that occupy the same RB set.

[0186] As an embodiment, there are no two PRACH opportunities among the multiple PRACH opportunities in the first PRACH opportunity group that occupy the same RB set.

[0187] As an embodiment, the first PRACH opportunity group only includes the multiple PRACH opportunities.

[0188] As an embodiment, the first PRACH opportunity group further includes PRACH opportunities other than the multiple PRACH opportunities.

[0189] As an embodiment, each of the multiple PRACH opportunities in the first PRACH opportunity group is within an RB set in the frequency domain.

[0190] As an embodiment, a PRACH opportunity other than the multiple PRACH opportunities in the first PRACH opportunity group overlaps with an intra-cell guardband in the frequency domain.

[0191] As an embodiment, the target frequency domain resource allocation includes multiple RBs.

[0192] As an embodiment, the advantages of the above method include: being beneficial to improving the transmission performance of the first PUSCH.

[0193] As an embodiment, the target frequency domain resource allocation includes 1 RB.

[0194] As an example, the statement "the target RB set is an RB set occupied by at least one PRACH opportunity in the first PRACH opportunity group" means that: the target RB set is an RB set occupied by a reference PRACH opportunity, and the reference PRACH opportunity is a PRACH opportunity in the first PRACH opportunity group.

[0195] As an example, the statement "the target RB set is an RB set occupied by at least one PRACH opportunity in the first PRACH opportunity group" means that: the first PRACH opportunity group occupies multiple RB sets, and the target RB set is one of the multiple RB sets.

[0196] As an example, the statement "the target RB set is an RB set occupied by at least one PRACH opportunity in the first PRACH opportunity group" means that: the multiple PRACH opportunities in the first PRACH opportunity group occupy multiple RB sets, and the target RB set is one of the multiple RB sets.

[0197] As an example, the target RB set includes at least one RB.

[0198] As an example, the target RB set is defined for a cell with a cell guard band.

[0199] As an example, the advantages of the above method include: being applicable to scenarios with a configured cell guard band.

[0200] As an example, the target RB set is an uplink RB set.

[0201] As an example, the target RB set is an uplink RB set of the active uplink BWP (Bandwidth Part)

[0244] Example 3

[0245] Embodiment 3 shows a schematic diagram of an embodiment of a radio protocol architecture for a user plane and a control plane according to the present application, as shown in the appendix Figure 3 as follows. Figure 3 It is a schematic diagram illustrating an embodiment of a radio protocol architecture for a user plane 350 and a control plane 300. Figure 3Show the radio protocol architecture of the control plane 300 for a first communication node device (UE, gNB, or RSU in V2X) and a second communication node device (gNB, UE, or RSU in V2X), or between two UEs, 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. Layer 1 will be referred to as PHY 301 in this text. Layer 2 (L2 layer) 305 is above PHY 301 and is responsible for the link between the first communication node device and the second communication node device, and between two UEs through PHY 301. Layer 2 305 includes a MAC (Medium Access Control) sublayer 302, an RLC (Radio Link Control) sublayer 303, and a PDCP (Packet Data Convergence Protocol) sublayer 304, and these sublayers terminate at the second communication 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 communication node device between the second communication 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 disordered 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 communication 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 communication node device and the first communication 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 of the first communication node device and the second communication 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 further includes an SDAP (Service Data Adaptation Protocol) sub-layer 356. The SDAP sub-layer 356 is responsible for the mapping between QoS flows and data radio bearers (DRBs) to support the diversity of services.

[0253] Example 4

[0254] Example 4 shows a schematic diagram of a first communication device and a second communication device according to this application, as shown in the appendix Figure 4 shown. Figure 4 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.

[0255] 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.

[0256] The second communication device 450 includes a controller / processor 459, a memory 460, a data source 467, a transmit processor 468, a receive processor 456, a multi-antenna transmit processor 457, a multi-antenna receive processor 458, a transmitter / receiver 454, and an antenna 452.

[0257] 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 functions 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 to 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 coding 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 space precoding on the coded 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.

[0258] 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 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 multi-carrier symbol stream and provides it 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 deinterleaves 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.

[0259] In the transmission from the second communication device 450 to the first communication device 410, at the second communication device 450, the 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 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 the L2 layer functions for 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. The transmit processor 468 performs modulation mapping and channel coding processing, and the 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 multi-carrier / single-carrier symbol streams, and after passing through the analog precoding / beamforming operation in the multi-antenna transmit processor 457, provides them to different antennas 452 via the transmitter 454. 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.

[0260] 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 functions 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 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 receive processor 472 and the receive processor 470. The receive processor 470 and the multi-antenna receive 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 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 packets from the UE 450. The upper layer data packets from the controller / processor 475 may be provided to the core network.
