The invention of the original application is named: 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 design of the reference signal in the 5G system needs to consider more requirements, such as faster data demodulation, better multi-user interference cancellation, uplink and downlink interference cancellation of dynamic TDD (i.e., flexible uplink and downlink timeslot position and/or ratio), and the like.

In 3GPP (3 rd Generation Partner Project) new air interface discussion, it is agreed that uplink DMRSs (Demodulation Reference signals) and downlink DMRSs corresponding to data channels both include at least one Front Loaded DMRS. In one slot (slot), a downlink preamble DMRS is located on one or two consecutive multicarrier symbols at a front end, and a position of a starting multicarrier symbol is fixed. In the OFDM system, a base station may configure one of two pattern types for an uplink DMRS and a downlink DMRS of each user equipment using higher layer signaling.

Disclosure of Invention

The inventor finds, through research, that in a 5G system, when pattern types of uplink DMRSs corresponding to uplink data channels configured by different user equipment are different, or when users respectively located in two adjacent cells perform uplink and downlink wireless communication in the same time slot and the pattern types of the uplink DMRSs and the downlink DMRSs respectively corresponding to the users are different, if the reference signals are configured on the same multicarrier symbol, orthogonality between the reference signals cannot be satisfied, and thus, there is a possibility that strong interference between the reference signals may be introduced. In addition, in order to reduce mutual interference between data and reference signals, data needs to be prevented from being transmitted on resources occupied by reference signals that may generate strong interference.

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 (User Equipment) of the present application may be applied to the base station, and vice versa.

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 a RRC (Radio Resource Control) sublayer 306 in layer 3 (L3 layer). 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 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 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 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 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 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 of the L1 layer. A 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 the 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, ciphering, 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. Appropriate coding and modulation schemes are 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. Controller/processor 475 is also responsible for error detection using the ACK and/or NACK protocol to support HARQ operations.
