Description

Method and device used in user equipment and base station for wireless communication

Technical Field

The present application relates to methods and apparatus in wireless communication systems, and more particularly, to methods and apparatus in Non-Orthogonal Multiple Access (Non-Orthogonal Multiple Access) wireless communication systems.

Background

In a conventional 3GPP (3rd Generation Partner Project) LTE (Long-term Evolution) system, uplink transmission at a UE (User Equipment) side often uses orthogonal multiple access. In the discussion of 5G NR (New Radio), in order to increase the number of UEs performing uplink transmission simultaneously, a plurality of UEs may employ Non-Orthogonal Multiple Access (Non-Orthogonal Multiple Access). In the non-orthogonal multiple access technology, in order to flexibly control the transmission rate of one UE, a multi-layer/multi-dimensional non-orthogonal multiple access manner is proposed and discussed. In multi-layer/multi-dimensional non-orthogonal Multiple Access transmission, a UE may transmit different data on the same time-frequency resource using Multiple Access signatures (Multiple Access signatures).

According to the conclusion of 3GPP RAN (Radio Access Network )1, the next generation wireless communication system will study the application of autonomous/grant free/configuration granted (granted grant) transmission mode in various application scenarios. In the autonomous/grant free/configuration granted (configured grant), the UE may autonomously perform uplink transmission in the statically (static) or quasi-statically (semi-static) configured air interface resource.

Disclosure of Invention

The inventor finds through research that the amount of data required by different services is different. In the next generation communication system, the amount of data transmitted in uplink may vary greatly due to the diversity of services. This change is dynamic and therefore cannot be completely matched by static or quasi-static resource allocation. Non-orthogonal multiple access supporting multi-layer/multi-dimensional transmission provides a simple and effective solution to the above problem: the UE may be configured with multiple access signatures and select the number of multiple access signatures used, i.e. the number of layers/dimensions of transmission, depending on the size of the actual amount of data.

In view of the above discussion, the present application discloses a solution. It should be noted that, without conflict, the embodiments and features in the embodiments in the user equipment of the present application may be applied to the base station, and vice versa.

Although not shown, the UE may have several protocol layers above the L2 layer 305, including a network layer (e.g., IP layer) terminating at the P-GW213 on the network side and an application layer terminating at the other end of the connection (e.g., far end UE, server, etc.). The PDCP sublayer 304 provides multiplexing between different radio bearers and logical channels. The PDCP sublayer 304 also provides header compression for upper layer packets to reduce radio transmission overhead, security by ciphering the packets, and handover support for UEs between gnbs. The RLC sublayer 303 provides segmentation and reassembly of upper layer packets, retransmission of lost packets, and reordering of packets to compensate for out-of-order reception due to HARQ (Hybrid Automatic Repeat reQuest). The MAC sublayer 302 provides multiplexing between logical and transport channels. The MAC sublayer 302 is also responsible for allocating the various radio resources (e.g., resource blocks) in one cell among the UEs. The MAC sublayer 302 is also responsible for HARQ operations. In the control plane, the radio protocol architecture for the UE and the gNB is substantially the same for the physical layer 301 and the L2 layer 305, but without the header compression function for the control plane. The Control plane also includes an RRC (Radio Resource Control) sublayer 306 in layer 3 (layer L3). The RRC sublayer 306 is responsible for obtaining radio resources (i.e., radio bearers) and configures the lower layers using RRC signaling between the gNB and the UE.

Example 4

Embodiment 4 illustrates a schematic diagram of an NR node and a UE as shown in fig. 4. Fig. 4 is a block diagram of a UE450 and a gNB410 in communication with each other in an access network.

gNB410 includes a controller/processor 475, a memory 476, a receive processor 470, a transmit processor 416, a channel encoder 477, a channel decoder 478, a transmitter/receiver 418, and an antenna 420.

The UE450 includes a controller/processor 459, memory 460, a data source 467, a transmit processor 468, a receive processor 456, a channel encoder 457, a channel decoder 458, a transmitter/receiver 454, and an antenna 452.

In the DL (Downlink), at the gNB, upper layer data packets from the core network are provided to a controller/processor 475. The controller/processor 475 implements the functionality of the L2 layer. In the DL, the controller/processor 475 provides header compression, ciphering, packet segmentation and reordering, multiplexing between logical and transport channels, and allocation of radio resources for the UE450 based on various priority metrics. Controller/processor 475 is also responsible for HARQ operations, retransmission of lost packets, and signaling to UE 450. The transmit processor 416 and channel encoder 477 perform various signal processing functions for the L1 layer (i.e., the physical layer). Channel encoder 477 performs coding and interleaving to facilitate Forward Error Correction (FEC) at UE 450. Transmit processor 416 performs mapping for 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)) and performs spatial precoding/beamforming on the encoded 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. Each transmitter 418 converts the baseband multi-carrier symbol stream provided by the transmit processor 416 into a radio frequency stream that is then provided to a different antenna 420.

In the DL (Downlink), at the UE450, each receiver 454 receives a signal through its respective antenna 452. 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. The receive processor 456 and channel decoder 458 implement the various signal processing functions of the L1 layer. Receive processor 456 converts the baseband multicarrier symbol stream 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 physical layer data is recovered into spatial streams destined for the UE450 through multi-antenna detection in the receive processor 456. The symbols on each spatial stream are demodulated and recovered at a receive processor 456 and soft decisions are generated. Channel decoder 458 then decodes and deinterleaves the soft decisions to recover the upper layer data and control signals transmitted by the gNB410 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 can be associated with a memory 460 that stores program codes and data. Memory 460 may be referred to as a computer-readable medium. In the DL, the controller/processor 459 provides demultiplexing between transport and logical channels, packet reassembly, deciphering, header decompression, control signal processing to recover upper layer data 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. The controller/processor 459 is also responsible for error detection using an Acknowledgement (ACK) and/or Negative Acknowledgement (NACK) protocol to support HARQ operations.

In the UL (Uplink), at the UE450, a data source 467 is used to provide upper layer data packets to the controller/processor 459. Data source 467 represents all protocol layers above the L2 layer. Similar to the transmit function at the gNB410 described in the DL, the controller/processor 459 implements header compression, encryption, packet segmentation and reordering, and multiplexing between logical and transport channels based on the radio resource allocation of the gNB410, implementing L2 layer functions for the user plane and the control plane. The controller/processor 459 is also responsible for HARQ operations, retransmission of lost packets, and signaling to the gNB 410. The channel encoder 457 performs channel encoding and the encoded data is modulated into a multi-carrier/single-carrier symbol stream by modulation performed by the transmit processor 468 and multi-antenna spatial precoding/beamforming processing and provided to different antennas 452 via the transmitter 454. Each transmitter 454 first converts the baseband symbol stream provided by the transmit processor 468 into a radio frequency symbol stream that is provided to the antenna 452.

In UL (Uplink), the function at the gNB410 is similar to the reception function at the UE450 described in DL. Each receiver 418 receives radio frequency signals through its respective antenna 420, converts the received radio frequency signals to baseband signals, and provides the baseband signals to a receive processor 470. Receive processor 470 and channel decoder 478 together implement the functions of layer L1. Controller/processor 475 implements the L2 layer functions. The controller/processor 475 may be associated with a memory 476 that stores program codes and data. Memory 476 may be referred to as a computer-readable medium. In the UL, 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. Upper layer packets from the controller/processor 475 may be provided to the core network. Controller/processor 475 is also responsible for error detection using the ACK and/or NACK protocol to support HARQ operations.
