Description

Technical Field

[0001] The present application relates to a transmission method and device in a wireless communication system, and in particular to a storage method and device for random access information. Background Art

[0002] Self-Organizing Networks (SON) include network self-configuration and self-optimization. To optimize the performance of random access (RA), the existing 3GPP (the 3rd Generation Partnership Project) protocol supports the user equipment (UE) to store the relevant information of random access after the random access process, and report the stored relevant information of random access based on base station scheduling.

[0003] With the continuous development of wireless communications, the requirements for mobility, transmission delay and system capacity are getting higher and higher. The 3GPP RAN (Radio Access Network) #94e meeting decided to study L1 (Layer 1, layer 1) / L2 (Layer 2, layer 2) triggered mobility (L1 / L2 Triggered Mobility, LTM) in the "NR (New Radio, New Air Interface) Further Enhancements (Further NR mobility enhancements)" research project (Work Item, WI); triggering the random access process on the LTM candidate cell through PDCCH order to obtain the timing advance (Timing Advance, TA) of the LTM candidate cell is a key technology. The 3GPP RAN94e meeting decided to study the uplink multiple transmit / receive point (multi-TRP / m-TRP) operation of two TAs in the "MIMO Evolution for Downlink and Uplink" research project; triggering the random access process on a TRP through the PDCCH (Physical downlink control channel) order to obtain the timing advance on a TRP is a key technology, among which, supporting two TRPs belonging to a serving cell and an additional cell respectively. The introduction of these technologies enables the UE (User Equipment) to send a Preamble on a cell outside the serving cell during the random access process.

[0004] The existing storage mechanism of random access related information does not consider the scenario that the UE sends a preamble in a cell other than the serving cell during the random access process, so that the UE reports the random access related information according to the existing protocol, which is not conducive to network self-configuration and self-optimization. Summary of the invention

[0005] The inventors found that when the UE sends a Preamble on a cell other than the serving cell during the random access process, the random access related information stored by the UE for reporting according to the existing protocol cannot reflect the type of the cell. Therefore, when the UE sends a Preamble on a cell other than the serving cell during the random access process, how the UE stores the random access related information for reporting needs to be studied.

[0006] In view of the above problems, the present application provides a solution for storing random access related information. In view of the above problem description, the NR system is used as an example. The present application is also applicable to scenarios such as LTE (Long-Term Evolution) or LTE-A (Long-Term Evolution Advanced) systems, and obtains technical effects similar to those of the NR system; further, although the present application provides a specific implementation method for the random access process, the present application can also be used in scenarios of processes equivalent to the random access process, and obtain technical effects similar to those of the random access process. Further, the use of a unified design scheme for different scenarios also helps to reduce hardware complexity and cost. Further, although the present application provides a specific implementation method for the random access process triggered by DCI (Downlink Control Information), the present application can also be used in scenarios of random access processes triggered by UE, and obtain technical effects similar to those of random access processes triggered by DCI. Further, although the present application provides a specific implementation method for LTM, the present application can also be used in scenarios such as m-TRPm-TA, and obtain technical effects similar to those of LTM. Further, although the original intention of this application is for the Uu air interface, this application can also be used for the PC5 port to achieve technical effects similar to the Uu air interface. Further, although the original intention of this application is for the terminal and base station scenario, this application is also applicable to the V2X (Vehicle-to-Everything) scenario, the communication scenario between the terminal and the relay, and the relay and the base station, to achieve technical effects similar to those in the terminal and base station scenario. Further, although the original intention of this application is for the terminal and base station scenario, this application is also applicable to the IAB (Integrated Access and Backhaul) communication scenario, to achieve technical effects similar to those in the terminal and base station scenario. Further, although the original intention of this application is for the terrestrial network (Terrestrial Network, TN) scenario, this application is also applicable to the non-terrestrial network (Non-Terrestrial Network, NTN) communication scenario, to achieve technical effects similar to those in the TN scenario. In addition, the use of a unified solution for different scenarios also helps to reduce hardware complexity and cost.

[0414] Example 4

[0415] Embodiment 4 shows a schematic diagram of a first communication device and a second communication device according to the present application, as shown in the attached figure. Figure 4 shown. Figure 4 is a block diagram of a first communication device 450 and a second communication device 410 communicating with each other in an access network.

[0416] The first 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.

[0417] The second communication device 410 includes a controller / processor 475 , a memory 476 , a receive processor 470 , a transmit processor 416 , a multi-antenna receive processor 472 , a multi-antenna transmit processor 471 , a transmitter / receiver 418 and an antenna 420 .

[0418] In transmission from the second communication device 410 to the first communication device 450, at the second 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 transmission from the second communication device 410 to the first 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 first communication device 450 based on various priority metrics. The controller / processor 475 is also responsible for retransmission of lost packets and signaling to the first 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 410, as well as 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, including codebook-based precoding and non-codebook-based precoding, and beamforming processing on the coded and modulated symbols to generate one or more spatial streams. The transmit processor 416 then maps each spatial stream to a subcarrier, multiplexes it with a reference signal (e.g., a pilot) in the time domain and / or frequency domain, and then uses an inverse fast Fourier transform (IFFT) to generate a physical channel carrying a time-domain multi-carrier symbol stream. The multi-antenna transmit processor 471 then performs a transmit analog precoding / beamforming operation on the time-domain multi-carrier symbol stream. Each transmitter 418 converts the baseband multi-carrier symbol stream provided by the multi-antenna transmit processor 471 into a radio frequency stream, and then provides it to a different antenna 420.

[0419] In the transmission from the second communication device 410 to the first communication device 450, at the first communication device 450, each receiver 454 receives a signal through its corresponding antenna 452. Each receiver 454 recovers the information modulated onto the RF carrier and converts the RF stream into a baseband multi-carrier symbol stream and provides it to the receiving processor 456. The receiving processor 456 and the multi-antenna receiving processor 458 implement various signal processing functions of the L1 layer. The multi-antenna receiving processor 458 performs a receiving analog precoding / beamforming operation on the baseband multi-carrier symbol stream from the receiver 454. The receiving processor 456 uses a fast Fourier transform (FFT) to convert the baseband multi-carrier symbol stream after the receiving analog precoding / beamforming operation 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 receiving processor 456, wherein the reference signal will be used for channel estimation, and the data signal is recovered after multi-antenna detection in the multi-antenna receiving processor 458 to any spatial stream destined for the first communication device 450. The symbols on each spatial stream are demodulated and recovered in the receiving processor 456, and soft decisions are generated. The receiving processor 456 then decodes and deinterleaves the soft decisions to recover the upper layer data and control signals transmitted by the second communication device 410 on 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 the L2 layer. The controller / processor 459 may be associated with a memory 460 that stores program codes and data. The memory 460 may be referred to as a computer-readable medium. In the transmission from the second communication device 410 to the second communication device 450, the controller / processor 459 provides multiplexing between transport and logical channels, packet reassembly, decryption, header decompression, and control signal processing to recover the upper layer data packets from the core network. The upper layer data packets are then provided to all protocol layers above the L2 layer. Various control signals may also be provided to L3 for L3 processing.

[0420] In the transmission from the first communication device 450 to the second communication device 410, at the first 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 function at the second communication device 410 described in the transmission from the second communication device 410 to the first 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 user plane and control plane. The controller / processor 459 is also responsible for the retransmission of lost packets and signaling to the second 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. Then, the transmit processor 468 modulates the generated spatial stream into a multi-carrier / single-carrier symbol stream, which is then provided to different antennas 452 via the transmitter 454 after analog precoding / beamforming operations 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.

[0421] In the transmission from the first communication device 450 to the second communication device 410, the function at the second communication device 410 is similar to the reception function at the first communication device 450 described in the transmission from the second communication device 410 to the first 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 the multi-antenna reception processor 472 and the reception processor 470. The reception processor 470 and the multi-antenna reception processor 472 jointly implement the functions of the L1 layer. The controller / processor 475 implements the L2 layer functions. The controller / processor 475 can be associated with a memory 476 storing program codes and data. The memory 476 can be referred to as a computer-readable medium. In the transmission from the first communication device 450 to the second communication device 410, the controller / processor 475 provides multiplexing between transport and logical channels, packet reassembly, decryption, header decompression, control signal processing to recover the upper layer data packets from the UE 450. Upper layer packets from controller / processor 475 may be provided to the core network.
