Description

Method and equipment used for wireless communication

Technical Field

The present invention relates to a transmission method and apparatus in a wireless communication system, and more particularly, to a transmission method and apparatus for improving efficiency of resource utilization and flexibility of a system in wireless communication.

Background

In the future, the application scenes of the wireless communication system are more and more diversified, and different application scenes put different performance requirements on the system. In order to meet different performance requirements of various application scenarios, research on New Radio interface (NR) technology (or fine Generation, 5G) is decided over 72 sessions of 3GPP (3rd Generation Partner Project) RAN (Radio Access Network), and standardization Work on NR is started over WI (Work Item) where NR passes through 75 sessions of 3GPP RAN.

In Communication, both LTE (Long Term Evolution) and 5G NR relate to Reliable system access, flexible resource allocation, scalable system structure, and efficient session management, which have important meanings for normal Communication between a base station and user equipment, reasonable scheduling of resources, and balancing of system load, and are a high throughput rate, meeting Communication requirements of various services, and a fundamental stone for improving spectrum utilization, which are essential for eMBB (enhanced Mobile BroadBand), URLLC (Ultra Reliable Low Latency Communication) and tc (enhanced Machine Type Communication). Meanwhile, in the Internet of Things in the field of industry, in V2X (Vehicular to X), communication between devices (Device to Device) is performed, in communication of unlicensed spectrum, in user communication quality monitoring, in Network planning optimization, in NTN (Non-terrestrial Network communication), in TN (terrestrial Network communication), in a mixture of the above various communication modes, there is a wide demand for wireless resource management and codebook selection for multiple antennas.

With the continuous increase of the scenes and the complexity of the system, higher requirements are provided for reducing the time delay, enhancing the reliability, enhancing the stability of the system, providing the flexibility for the service and saving the power, and meanwhile, the compatibility between different versions of different systems needs to be considered during the design of the system.

Disclosure of Invention

In various communication scenes, if a user needs to initiate communication, the user needs to access a network firstly; during the communication, due to the problems of the transmitting side or the receiving side, or due to the influence of the communication propagation delay, or due to non-ideal device factors, the signal quality is reduced, even communication interruption occurs, and the user equipment needs to be accessed again. When one access is not successful, the user needs to access again, and the total access delay is increased. In order to reduce the interruption time, improve the success rate of access, quickly access the system, reduce the overall communication delay, and make a quick, reliable and stable access method important, especially when the distance between nodes is long, or other reasons, such as signal detection failure, cause a large delay in the process, the access process will generate further uncertainty, and at the same time, communication interruption will be further caused. This can lead to a reduction in resource efficiency, difficulty in ensuring communication quality, inability of nodes to establish effective communication bearers, and various complications. On the other hand, the delay in the communication process may cause inaccurate measurement, or the measurement result is out of date, but the measurement itself has a certain error, which may cause the user to initiate access using improper power, or may cause the detection requirement of the access signal to be not satisfied even though the maximum transmission power is used due to the large propagation loss of the user signal, thereby causing access difficulty and increasing the access delay. In communication, propagation delays of users may be different, which makes it difficult for users to perform uniform control and need to perform separate processing, and how to design a proper set of access methods in this situation is a problem to be solved. In addition, the design criteria, accuracy and geographical location of different systems may be different, and various communication scenarios may be mixed together, which all bring problems to the design of the systems.

In view of the above, the present application provides a solution.

It should be noted that, in the case of no conflict, the embodiments and features in the embodiments in any node of the present application may be applied to any other node. The embodiments and features of the embodiments of the present application may be combined with each other arbitrarily without conflict. Furthermore, it should be noted that, in the above problem description, the IoT scenario is only an example of one application scenario of the solution provided in the present application; the application is also equally applicable to scenarios such as non-terrestrial networks, achieving technical effects similar to those in IoT scenarios. Similarly, the present application is also applicable to scenarios where, for example, a UAV (Unmanned Aerial Vehicle) or an onboard network is present, to achieve technical effects in IoT-like scenarios. Furthermore, employing a unified solution for different scenarios (including but not limited to NTN and TN network scenarios) also helps to reduce hardware complexity and cost.

As an example, compared with the conventional scheme, the method has the following advantages:

when the time difference of the user signal arriving at the serving cell is large due to the large cell and the like, and different random access signals need to be used, how to correctly determine the random access signals is an important problem. When a user is positioned at the edge of a cell or the signal of the user experiences larger time delay, a longer sequence is needed to generate a random access signal, and when the user is positioned at the center of the cell or the signal of the user experiences smaller time delay, a shorter sequence can be used to generate the random access signal; since a random access signal generated using a longer sequence requires more radio resources, it is necessary to restrict a user who can generate a random access signal using a shorter sequence to generate a random access signal using a shorter sequence. The application sets a specific condition to be associated with the first threshold, the first time length and the first position information, so that a user can correctly determine the sequence required to be used. In particular, when the user has previously used a short sequence and moved from one cell to another, or from the area covered by one beam to the area covered by another beam, the sequence used to generate the random access can still be correctly selected. These are all something that conventional solutions do not have.

Example 4

Embodiment 4 shows a schematic diagram of a first communication device and a second communication device according to the present application, as shown in fig. 4. Fig. 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.

The first communications 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.

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

In the 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 layer L2. In transmissions from the second communications device 410 to the first communications 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 communications 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 constellation 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. Transmit processor 416 then maps each spatial stream to subcarriers, multiplexes with reference signals (e.g., pilots) in the time and/or frequency domain, and then uses an Inverse Fast Fourier Transform (IFFT) to generate the physical channels carrying the time-domain multicarrier symbol streams. The multi-antenna transmit processor 471 then performs transmit analog precoding/beamforming operations on the time domain multi-carrier symbol stream. Each transmitter 418 converts the baseband multicarrier symbol stream provided by the multi-antenna transmit processor 471 into a radio frequency stream that is then provided to a different antenna 420.

In a transmission from the second communications apparatus 410 to the first communications apparatus 450, each receiver 454 receives a signal through its respective antenna 452 at the first communications apparatus 450. Each receiver 454 recovers information modulated onto a radio frequency carrier and converts the radio frequency stream into a baseband multi-carrier symbol stream that is provided to a receive processor 456. Receive processor 456 and multi-antenna receive processor 458 implement the various signal processing functions of the L1 layer. A multi-antenna receive processor 458 performs receive analog precoding/beamforming operations on the baseband multi-carrier symbol stream from the receiver 454. Receive processor 456 converts the baseband multicarrier symbol stream after the receive analog precoding/beamforming operation from the time domain to the frequency domain using a Fast Fourier Transform (FFT). In the frequency domain, the physical layer data signals and the reference signals to be used for channel estimation are demultiplexed by the receive processor 456, and the data signals are subjected to multi-antenna detection in the multi-antenna receive processor 458 to recover any spatial streams destined for the first communication device 450. The symbols on each spatial stream are demodulated and recovered at a receive processor 456 and soft decisions are generated. The receive processor 456 then decodes and deinterleaves the soft decisions to recover the upper layer data and control signals transmitted by the second communications device 410 on the physical channel. The upper layer data and control signals are then provided to a controller/processor 459. The controller/processor 459 implements the functionality of the L2 layer. The controller/processor 459 may be associated with a memory 460 that stores program codes and data. Memory 460 may be referred to as a computer-readable medium. In transmissions from the second communications device 410 to the second communications device 450, the controller/processor 459 provides demultiplexing between transport and logical channels, packet reassembly, deciphering, header decompression, control signal processing to recover upper layer packets from the core network. The upper layer packet is then provided to all protocol layers above the L2 layer. Various control signals may also be provided to L3 for L3 processing.

In a transmission from the first communications device 450 to the second communications device 410, a data source 467 is used at the first communications device 450 to provide upper layer data packets to a controller/processor 459. Data source 467 represents all protocol layers above the L2 layer. Similar to the send function at the second communications apparatus 410 described in the transmission from the second communications apparatus 410 to the first communications apparatus 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 retransmission of lost packets and signaling to said second communications device 410. A transmit processor 468 performs modulation mapping, channel coding, and digital multi-antenna spatial precoding by a multi-antenna transmit processor 457 including codebook-based precoding and non-codebook based precoding, and beamforming, and the transmit processor 468 then modulates the resulting spatial streams into multi-carrier/single-carrier symbol streams, which are provided to different antennas 452 via a transmitter 454 after analog precoding/beamforming 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 provides the radio frequency symbol stream to the antenna 452.

In a transmission from the first communication device 450 to the second communication device 410, the functionality at the second communication device 410 is similar to the receiving functionality 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 an rf signal through its respective antenna 420, converts the received rf signal to 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 multiple antenna receive processor 472 collectively implement the functionality of the L1 layer. Controller/processor 475 implements the L2 layer functions. The controller/processor 475 can be associated with a memory 476 that stores program codes and data. Memory 476 may be referred to as a computer-readable medium. In transmission from the first communications device 450 to the second communications device 410, the controller/processor 475 provides demultiplexing between transport and logical channels, packet reassembly, deciphering, header decompression, control signal processing to recover upper layer packets from the UE 450.
