Description

[0001] This application is a divisional application of the following original application:

[0002] --Original application date: August 10, 2017

[0003] --Original application number: 201710680083.7

[0004] --Original application title: A method and apparatus for use in user equipment and base stations for wireless communication Technical Field

[0005] This application relates to methods and apparatus for transmitting wireless signals in wireless communication systems, and more particularly to methods and apparatus for transmitting wireless signals in wireless communication systems supporting cellular networks. Background Technology

[0006] In wireless communication systems, reference signals have always been an essential means of ensuring communication quality. Compared with traditional LTE (Long Term Evolution) systems, the design of reference signals in 5G systems needs to consider more requirements, such as faster data demodulation, better multi-user interference cancellation, and dynamic TDD (i.e., flexible uplink and downlink time slot positions and / or ratios) uplink and downlink interference cancellation.

[0007] In the 3GPP (3rd Generation Partner Project) New Radio discussions, it was agreed that both the uplink DMRS (Demodulation Reference Signal) and downlink DMRS for the data channel should include at least one front-loaded DMRS. Within a slot, the downlink front-loaded DMRS is located on one or two consecutive multicarrier symbols at the front end, and the position of the starting multicarrier symbol is fixed. In OFDM systems, the base station can configure one of two pattern types for each user equipment's uplink and downlink DMRS using higher-layer signaling. Summary of the Invention

[0008] The inventors discovered through research that in 5G systems, when different user equipments are configured with uplink data channels corresponding to different uplink DMRS pattern types, or when users located in two adjacent cells are conducting uplink and downlink wireless communications on the same time slot with different uplink and downlink DMRS pattern types, configuring these reference signals on the same multicarrier symbol cannot satisfy the orthogonality between the reference signals, potentially introducing strong interference between them. Furthermore, to reduce mutual interference between data and reference signals, data should avoid being transmitted on resources occupied by reference signals that may generate strong interference.

[0009] To address the aforementioned problems, this application discloses a solution. It should be noted that, unless otherwise specified, the embodiments and features described in the UE (User Equipment) of this application can be applied to base stations, and vice versa. Furthermore, unless otherwise specified, the embodiments and features described in the embodiments of this application can be arbitrarily combined with each other.

[0010] This application discloses a method for use in a user equipment for wireless communication, characterized by comprising:

[0011] - Receive the first signaling;

[0012] - Transmit the first radio signal in the first time-frequency resource;

[0013] Wherein, the first signaling is used to determine a first set of resource particles, some or all of which belong to the first time-frequency resource; the resource particles occupied by the first radio signal are within the first time-frequency resource and outside the first set of resource particles; the first radio signal includes a first radio sub-signal and a second radio sub-signal; the target reference pattern is a pattern composed of the resource particles occupied by the first radio sub-signal; the first set of resource particles is related to at least one of {the time-domain resource occupied by the first radio sub-signal, and the type of the target reference pattern}; for a given set of all transmit antenna ports used to transmit the first radio sub-signal, the type of the target reference pattern is one of a first pattern type and a second pattern type.

[0014] As an example, the advantage of the above method is that by associating the first resource particle set with at least one of {the time-domain resources occupied by the first wireless sub-signal, and the type of the target reference pattern}, the signaling overhead of the base station equipment for indicating the time-frequency domain location of the first resource particle set can be reduced.

[0015] According to one aspect of this application, the method is characterized in that the time-domain position of the initial multicarrier symbol occupied by the first wireless sub-signal in the first time-frequency resource is one of a first position and a second position; the first position is fixed in the first time-frequency resource.

[0016] According to one aspect of this application, the above method is characterized by comprising:

[0017] - Receive the second signaling;

[0018] The second signaling is used to determine that the time-domain position of the initial multicarrier symbol occupied by the first radio sub-signal in the first time-frequency resource is one of the first position and the second position.

[0019] As an example, the advantage of the above method is that when the first wireless sub-signal is an uplink reference signal, and when the pattern types of the uplink reference signals of different user equipment are different, or when users located in two adjacent cells respectively perform uplink and downlink wireless communication on the first time-frequency resource and the pattern types of the corresponding uplink and downlink reference signals are different, if the uplink reference signal is mapped to a fixed position in the first time-frequency resource that is the same as the downlink reference signal, such as the first position, then strong interference will occur between these reference signals. However, this application, by flexibly configuring the time-domain position of the initial multi-carrier symbol occupied by the uplink reference signal in the first time-frequency resource to one of the first position and the second position, can map these multiple reference signals to the first position and the second position respectively, realizing time-division multiplexing of the reference signals, thereby avoiding mutual interference between the reference signals.

[0028] As an example, the advantage of the above method is that when the pattern of the first resource particle set in the first time-frequency resource coincides with the set of the K target patterns, and the second wireless sub-signal is data, by avoiding mapping the data onto the first resource particle set, mutual interference between the data and the K reference signals is avoided.

UMTS corresponds to Universal Mobile Telecommunications System. EPS can interconnect with other access networks, but these entities / interfaces are not shown for simplicity. (See attached...) Figure 2As shown, EPS provides packet-switched services; however, those skilled in the art will readily understand that the various concepts presented throughout this application can be extended to networks providing circuit-switched services. E-UTRAN-NR includes NR Node B (gNB) 203 and other gNBs 204. gNB 203 provides user and control plane protocol termination to UE 201. gNB 203 can connect to other gNBs 204 via an X2 interface (e.g., backhaul). gNB 203 may also be referred to as a base station, base transceiver station, radio base station, radio transceiver, transceiver function, Basic Services Set (BSS), Extended Services Set (ESS), TRP (Transmitter-Receiver Point), or some other suitable term. gNB 203 provides UE 201 with access to 5G-CN / EPC 210. Examples of UE201 include cellular phones, smartphones, Session Initiation Protocol (SIP) phones, laptop computers, personal digital assistants (PDAs), satellite radios, global positioning systems, multimedia devices, video devices, digital audio players (e.g., MP3 players), cameras, game consoles, drones, aircraft, narrowband physical network devices, machine-type communication devices, land vehicles, automobiles, wearable devices, or any other similar functional devices.

[0136] Example 3

[0137] Example 3 illustrates a schematic diagram of an embodiment of a wireless protocol architecture for the user plane and control plane, as shown in the attached diagram. Figure 3 As shown.

[0138] Appendix Figure 3 This is a schematic diagram illustrating an embodiment of a radio protocol architecture for the user plane and control plane, with appended... Figure 3The radio protocol architecture for the UE and gNB is illustrated using 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. L1 layer will be referred to herein as PHY301. Layer 2 (L2 layer) 305 sits above PHY301 and is responsible for the link between the UE and gNB via PHY301. In the user plane, L2 layer 305 includes the MAC (Medium Access Control) sublayer 302, the RLC (Radio Link Control) sublayer 303, and the PDCP (Packet Data Convergence Protocol) sublayer 304, which terminate at the gNB on the network side. Although not illustrated, the UE may have several upper layers above 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., a remote UE, server, etc.). PDCP sublayer 304 provides multiplexing between different radio bearers and logical channels. PDCP sublayer 304 also provides header compression for upper-layer packets to reduce radio transmission overhead, provides security through packet encryption, and provides handover support between gNBs to UEs. RLC sublayer 303 provides segmentation and reassembly of upper-layer packets, retransmission of lost packets, and packet reordering to compensate for out-of-order reception due to HARQ. MAC sublayer 302 provides multiplexing between logical and transport channels. MAC sublayer 302 is also responsible for allocating various radio resources (e.g., resource blocks) within a cell among UEs. MAC sublayer 302 is also responsible for HARQ operations. In the control plane, the radio protocol architecture for UEs and gNBs is largely the same for physical layer 301 and L2 layer 305, but header compression functionality for the control plane is absent. The control plane also includes the RRC (Radio Resource Control) sublayer 306 in layer 3 (L3). RRC sublayer 306 is responsible for obtaining radio resources (i.e., radio bearers) and configuring the lower layer using RRC signaling between the gNB and the UE.

[0147] Example 4

[0148] Example 4 illustrates a schematic diagram of the evolved node and the UE, as shown in the attached diagram. Figure 4 As shown.

[0149] Appendix Figure 4This is a block diagram of gNB410 communicating with UE450 in the access network. In the DL (Downlink), upper-layer packets from the core network are provided to controller / processor 475. Controller / processor 475 implements L2 layer functionality. In the DL, controller / processor 475 provides header compression, encryption, packet segmentation and reordering, multiplexing between logical and transport channels, and radio resource allocation to UE450 based on various priority metrics. Controller / processor 475 is also responsible for HARQ operation, retransmission of lost packets, and signaling to UE450. Transmit processor 416 implements various signal processing functions for L1 layer (i.e., physical layer). Signal processing functions include decoding and interleaving to facilitate forward error correction (FEC) at UE450 and mapping to signal clusters based on various modulation schemes (e.g., Binary Phase Shift Keying (BPSK), Quadrature Phase Shift Keying (QPSK), M-Phase Shift Keying (M-PSK), M-QAM). The decoded 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., a pilot) in the time and / or frequency domains, and subsequently combined using an inverse fast Fourier transform (IFFT) to generate a physical channel carrying the time-domain multicarrier symbol stream. The multicarrier streams are spatially pre-decoded to generate multiple spatial streams. Each spatial stream is then provided to a different antenna 420 via transmitter 418. Each transmitter 418 modulates an RF carrier with the corresponding spatial stream for transmission. At UE450, each receiver 454 receives the signal through its corresponding antenna 452. Each receiver 454 recovers the information modulated onto the RF carrier and provides the information to the receiver processor 456. The receiver processor 456 implements various signal processing functions of the L1 layer. The receiver processor 456 performs spatial processing on the information to recover any spatial stream destined for the UE 450. If multiple spatial streams are destined for the UE 450, they can be combined by the receiver processor 456 into a single multicarrier symbol stream. The receiver processor 456 then uses a Fast Fourier Transform (FFT) to transform the multicarrier symbol stream from the time domain to the frequency domain. The frequency domain signal includes 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 cluster points transmitted by the gNB 410 and generating soft decisions. The soft decisions are then decoded and deinterleaved to recover the data and control signals originally transmitted by the gNB 410 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 may be associated with memory 460, which stores program code and data. Memory 460 may be referred to as computer-readable media.In the DL (Layered Transmission), the controller / processor 459 provides multiplexing, packet reassembly, decryption, header decompression, and control signal processing between the transport and logical channels to recover upper-layer packets from the core network. The upper-layer packets are then provided to all protocol layers above L2. Various control signals can also be provided to L3 for L3 processing. The controller / processor 459 is also responsible for error detection using ACK and / or NACK protocols to support HARQ operation. In the UL (Uplink), a data source 467 is used to provide upper-layer packets to the controller / processor 459. The data source 467 represents all protocol layers above L2. Similar to the functionality described in the DL transmission combined with gNB410, the controller / processor 459 implements L2 for the user plane and control plane by providing header compression, encryption, packet segmentation and reordering, and multiplexing between the logical and transport channels through gNB410-based radio resource allocation. The controller / processor 459 is also responsible for HARQ operation, retransmission of lost packets, and signaling to the gNB 410. The transmit processor 468 selects appropriate coding and modulation schemes and facilitates spatial processing. The spatial stream generated by the transmit processor 468 is provided to different antennas 452 via individual transmitters 454. Each transmitter 454 modulates an RF carrier with the corresponding spatial stream used for transmission. UL transmission is processed at the gNB 410 in a manner similar to that described in conjunction with the receiver functionality at the UE 450. Each receiver 418 receives signals through its corresponding antenna 420. Each receiver 418 recovers the information modulated onto the RF carrier and provides the information to the receive processor 470. The receive processor 470 may implement the L1 layer. The controller / processor 475 implements the L2 layer. The controller / processor 475 may be associated with a memory 476 storing program code and data. The memory 476 may be referred to as computer-readable media. In the UL, the controller / processor 475 provides multiplexing, packet reassembly, decryption, header decompression, and control signal processing between the transport and logical channels to recover upper-layer packets from the UE 450. Upper-layer packets from the controller / processor 475 are then provided to the core network. The controller / processor 475 is also responsible for error detection using ACK and / or NACK protocols to support HARQ operation.
