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 for transmitting a radio signal in a wireless communication system, and more particularly, to a method and an apparatus for transmitting a radio signal in a wireless communication system supporting a cellular network.

Background

In a wireless communication system, a reference signal has been one of the necessary means for securing communication quality. Compared with the conventional LTE (Long Term Evolution) system, the NR (New Radio) system supports both low band (<6GHz) and high band (>6GHz) transmissions. In the high frequency band, the influence of Phase noise on the channel estimation performance is not negligible, so that it has been agreed to transmit PTRS (Phase-Tracking Reference Signal) for Phase Tracking at the receiving end in 3GPP (3rd Generation Partner Project) NR discussion, and the channel estimation accuracy is improved by performing Phase compensation in channel estimation.

In the 3gpp nr discussion, it has been agreed to configure a UE (User Equipment) with one or two DMRS (Demodulation Reference Signal) port groups, one PTRS port being associated with one DMRS port in one DMRS port group, and being carried on one subcarrier corresponding to the DMRS port within one given RB (Resource Block). The number of uplink PTRS ports is related to the number of uplink DMRS port groups and the number of oscillators of radio frequency channels used for transmitting uplink DMRSs by the UE side. The number of downlink PTRS ports is related to the number of downlink DMRS port groups and the number of oscillators of radio frequency channels used for transmitting downlink DMRSs by a base station side. In addition, the PTRS is also related to a Modulation and Coding Scheme (MCS) and a scheduling bandwidth allocated to data transmission, and the PTRS is transmitted only when the MCS and the scheduling bandwidth take values within a certain range, otherwise, the PTRS is not transmitted.

The inventors discovered through research that, in an NR system, when the number of uplink DMRS port groups is 2, whether the two groups of DMRS ports can share one uplink PTRS port is related to the number of oscillators used by the UE side to transmit the two groups of DMRS. At this time, if the base station cannot know whether the radio frequency channel used by the UE side to transmit the two sets of DMRS is a repeater, in order to ensure channel estimation performance, the base station needs to configure 2 uplink PTRS ports to respectively correspond to the two sets of DMRS ports. If only one oscillator is used for sending the two groups of DMRSs on the UE side, the phase noises corresponding to the two groups of DMRSs can be considered to be the same, and only 1 uplink PTRS port needs to be configured, so that the pilot frequency overhead is reduced, and the system performance is improved. Therefore, how to get the UE-side oscillator-related information by the base station is a problem to be solved. In addition, since the NR system supports a small-slot (mini-slot), URLLC (Ultra-Reliable and Low Latency Communications, high-reliability and Low-Latency Communications), unlicensed uplink transmission, dynamic TDD, and the like, the change of interference may be faster than that of the conventional LTE system, and therefore, for more accurate interference information, the pilot frequency used for interference measurement needs to be dense in the time domain and may be sparse in the frequency domain.

In view of the above, the present application discloses a solution. It should be noted that, without conflict, the embodiments and features in the embodiments in the UE of the present application may be applied to the base station, and vice versa. Further, the embodiments and features of the embodiments of the present application may be arbitrarily combined with each other without conflict.

Example 3

Embodiment 3 illustrates a schematic diagram of an embodiment of radio protocol architecture for the user plane and the control plane, as shown in fig. 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. Although not shown, the UE may have several upper layers above the L2 layer 305, including a network layer (e.g., IP layer) that terminates at the P-GW213 on the network side and an application layer that terminates 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 data packets to reduce radio transmission overhead, security by ciphering the data 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. 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 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).

Example 4

Embodiment 4 illustrates a schematic diagram of an evolved node and a UE, as shown in fig. 4.

Fig. 4 is a block diagram of a gNB410 in communication with a UE450 in an access network. In the DL (Downlink), upper layer packets from the core network are provided to the 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 radio resource allocation to 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 implements various signal processing functions for the L1 layer (i.e., the physical layer). The signal processing functions include decoding and interleaving to facilitate Forward Error Correction (FEC) at the UE450 and mapping to 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 coded and modulated symbols are then split into parallel streams. Each stream is then mapped to a multicarrier subcarrier, multiplexed with a reference signal (e.g., pilot) in the time and/or frequency domain, and then combined together using an Inverse Fast Fourier Transform (IFFT) to produce a physical channel carrying a time-domain multicarrier symbol stream. The multi-carrier stream is spatially pre-decoded to produce a plurality of spatial streams. Each spatial stream is then provided via a transmitter 418 to a different antenna 420. Each transmitter 418 modulates an RF carrier with a respective spatial stream for transmission. At the UE450, each receiver 454 receives a signal through its respective antenna 452. Each receiver 454 recovers information modulated onto an RF carrier and provides the information to a receive processor 456. The receive processor 456 performs various signal processing functions at the L1 level. The receive processor 456 performs spatial processing on the information to recover any spatial streams destined for the UE 450. If multiple spatial streams are destined for UE450, they may be combined into a single multicarrier symbol stream by receive processor 456. A receive processor 456 then converts the multicarrier symbol stream from the time-domain to the frequency-domain using a Fast Fourier Transform (FFT). The frequency domain signal comprises a separate multicarrier symbol stream for each subcarrier of the multicarrier signal. The symbols on each subcarrier, as well as the reference signal, are recovered and demodulated by determining the most likely signal constellation point transmitted by the gNB410, and generating soft decisions. The soft decisions are then decoded and deinterleaved to recover the data and control signals that were originally transmitted by the gNB410 on the physical channel. The data and control signals are then provided to a controller/processor 459. The controller/processor 459 implements 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 packets from the core network. The upper layer packets are 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), a data source 467 is used to provide the upper layer packet to the controller/processor 459. Data source 467 represents all protocol layers above the L2 layer. Similar to the functionality described in connection with the DL transmission of the gNB410, the controller/processor 459 implements the L2 layer for the user plane and the control plane by providing header compression, encryption, packet segmentation and reordering, and multiplexing between logical and transport channels based on the radio resource allocation of the gNB 410. The controller/processor 459 is also responsible for HARQ operations, retransmission of lost packets, and signaling to the gNB 410. An appropriate coding and modulation scheme is selected and spatial processing is facilitated by a transmit processor 468. The spatial streams generated by the transmit processor 468 are provided to different antennas 452 via separate transmitters 454. Each transmitter 454 modulates an RF carrier with a respective spatial stream for transmission. UL transmissions are processed at the gNB410 in a manner similar to that described in connection with receiver functionality at the UE 450. Each receiver 418 receives a signal through its respective antenna 420. Each receiver 418 recovers information modulated onto an RF carrier and provides the information to a receive processor 470. Receive processor 470 may implement the L1 layer. The controller/processor 475 implements the L2 layer. 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.
