Description

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

Technical Field

The present application relates to a method and an apparatus in a wireless communication system, and more particularly, to a method and an apparatus in a wireless communication system supporting uplink transmission based on a configuration granted (configured grant).

Background

In a conventional 3GPP (3rd Generation Partner Project) LTE (Long-term Evolution) system, uplink transmission at a UE (User Equipment) side often depends on dynamic grant (dynamic grant) of a base station. In a 5G NR (New Radio Access Technology) system, the UE may perform uplink transmission based on a configuration grant (configured grant) in an air interface resource pre-configured by the base station, so as to reduce overhead of an air interface signaling and improve spectrum efficiency of the system. In the configuration grant uplink transmission, the base station configures a periodic Resource pool and an MCS (modulation and coding scheme) to the UE in a semi-static (semi-static) manner through a higher layer signaling (high layer) such as an RRC (Radio Resource Control) signaling, and the UE determines whether to send a Radio signal in the Resource pool configured by the base station. In order to ensure the reliability of the configuration granted uplink transmission, the base station may configure a repetition number, which instructs the UE to repeatedly send the same TB (Transport Block) in one period.

Disclosure of Invention

The inventor finds out through research that, because the time when the TB arrives at the UE is uncertain, when the UE transmits one TB for the first time, the number of repeated transmissions that can be supported by the remaining time resource in the time resource allocated to the configuration grant in one period may not reach the number of repeated transmissions configured by the base station. This situation causes problems such as degradation of reception quality and additional delay.

In view of the above, the present application discloses a solution. Without conflict, embodiments and features in embodiments in the user equipment of the present application may be applied to the base station and vice versa. The embodiments and features of the embodiments of the present application may be combined with each other arbitrarily without conflict.

The application discloses a method used in a user equipment for wireless communication, which is characterized by comprising the following steps:

receiving first information;

transmitting M1 wireless signals in M1 time windows of the M time windows, respectively;

wherein the first information indicates a first MCS and a second MCS, and the spectral efficiency corresponding to the first MCS is greater than the spectral efficiency corresponding to the second MCS; the M1 wireless signals each carrying a first bit block, the user equipment transmitting wireless signals carrying the first bit block in only the M1 time windows of the M time windows; the M1 wireless signals each employ a target MCS, the target MCS being the first MCS or the second MCS, the target MCS being related to a position of an earliest one of the M1 time windows in the M time windows; the M is a positive integer greater than 1, and the M1 is a positive integer no greater than the M.

As an embodiment, the problem to be solved by the present application is: in the configuration granted uplink transmission, when the number of times of repeated sending does not reach the preset number of times of repetition, how to improve the performance of uplink transmission and avoid extra time delay. The above method solves this problem by configuring two MCSs, corresponding to higher and lower spectral efficiencies, respectively, and allowing the UE to select an MCS based on the location of the first transmission within a period.

As an embodiment, the method is characterized in that the M time windows are time resources allocated to a configuration grant (configured grant) in one period, and an earliest one of the M1 wireless signals is a first transmission of the first bit block. If the first transmission of the first bit block occurs at an earlier time in the M time windows, the remaining time resources allocated to the configuration grant during this period can support sufficient retransmissions of the first bit block, and the UE employs a larger MCS. If the first transmission of the first bit block occurs at a later time in the M time windows, the time resource allocated to the configuration grant remaining in this period can only support a few retransmissions or even no retransmissions of the first bit block, and the ue employs a smaller MCS to compensate for the loss of combining gain due to the missing retransmissions by a higher coding gain.

As an embodiment, the method is characterized in that if the first transmission of the first bit block occurs at a later time in the M time windows, the user equipment can decide which MCS to use according to the size of the TB to be transmitted. If the TB to be transmitted is smaller, even a smaller MCS can be completely mapped into the time-frequency resource allocated to one repetition, and the user equipment adopts the smaller MCS to obtain higher coding gain. Otherwise, to avoid splitting one large TB into two small TBs to be transmitted on two periods, respectively, the user equipment still uses a larger MCS.

As an example, the above method has the benefits of: in the uplink transmission based on the configuration grant, the receiving quality reduction caused by the reduction of the repeated sending times is compensated by using higher coding gain, the transmission quality is ensured, and the additional time delay is avoided.

Example 3

Embodiment 3 illustrates a schematic diagram of an embodiment of a user plane and control plane radio protocol architecture as shown in figure 3.

Fig. 3 is a schematic diagram illustrating an embodiment of radio protocol architecture for the user plane and the control plane, fig. 3 showing the radio protocol architecture for the UE and the gNB in 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. The L1 layer will be referred to herein as PHY 301. Layer 2(L2 layer) 305 is above PHY301 and is responsible for the link between the UE and the gNB through PHY 301. In the user plane, the L2 layer 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, which terminate at the gNB on the network side.

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 layer L2. 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. The controller/processor 475 is also responsible for HARQ operations, retransmission of lost packets, and signaling to the 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 that carry 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 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 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.
