- -application number of the original application: 201710436988X
The invention of the original application is named: method and device used in multi-antenna user equipment and base station
Technical Field
The present application relates to methods and apparatus to be used for multiple antennas, and more particularly, to methods and apparatus for physical layer control signaling reception.
Background
In an existing LTE (Long Term Evolution) system, for a Downlink subframe, a UE (User Equipment) searches for a corresponding DCI (Downlink Control Information) in the Downlink subframe. The Downlink Grant (Grant) tends to schedule the DL-SCH (Downlink Shared Channel) of the current subframe, and the Uplink Grant tends to schedule the UL-SCH (Uplink Shared Channel) of the subsequent subframe. The system allocates two different DCI formats (formats) to the UE through high-level signaling, the two different DCI formats respectively correspond to two different load sizes (Payload Size), and the UE respectively performs Blind detection (Blind Decoding) based on the different load sizes when receiving the DCI. In a 5G communication system, Beamforming (Beamforming) will be applied in a large amount, and a DCI blind detection method based on a Beamforming application scenario needs to be considered again.
Disclosure of Invention
In the 5G system, the concepts of BR (Beam Recovery) and BLF (Beam Link Failure) are under discussion. The above concept is introduced to ensure that when a UE finds that the channel quality corresponding to one beam is bad, the UE can quickly switch to be served under another beam. The BR and BLF processes do not trigger RRC (Radio Resource Control) layer processes, which is advantageous in ensuring fast handover.
When the UE is in the BLF report and BR process, a simple DCI blind detection mode is that the UE still performs blind detection on two or more DCI formats based on RRC configuration; however, this approach may increase the number of unnecessary blind detections for the UE. The present application provides a solution to the above problems. It should be noted that the embodiments and features of the embodiments of the present application may be arbitrarily combined with each other without conflict. For example, embodiments and features in embodiments in the user equipment of the present application may be applied in the base station and vice versa.
The application discloses a method used in user equipment for multi-antenna transmission, which is characterized by comprising the following steps:

-for a first signalling and a second signalling, monitoring only said first signalling in a first time window;
wherein the first time window and the first time slot are correlated, the first time window comprising a positive integer number of time slots; the sending of the first information is used to trigger a jettisoning of monitoring the second signaling in the first time window; the first signaling and the second signaling are physical layer signaling, respectively; only one of the first signaling and the second signaling comprises a first set of domains, the first set of domains comprising a positive integer number of domains.
As an example, the above method has the benefits of: and the user equipment only monitors the first signaling in a first time window, thereby reducing the receiving complexity of the user equipment to the physical layer dynamic signaling.

As an embodiment, the design principle of the above method is that: when the user equipment sends the first information, the user equipment is already in the process of BR, and the quality of a beam currently detected by the user equipment is not good.

According to an aspect of the application, the above method is characterized in that the number of information bits comprised by the first signaling and the number of information bits comprised by the second signaling are different.

According to an aspect of the application, the above method is characterized in that the first signaling comprises a smaller number of information bits than the second signaling.

According to one aspect of the application, the above method is characterized by comprising:
-receiving a target wireless signal;
wherein a measurement result for the target wireless signal below a certain threshold is used to trigger the first information.
As an embodiment, the above method is characterized in that: the particular threshold corresponds to a given beam used to transmit the target wireless signal, the particular threshold being beam-specific.
As an example, the above method has the benefits of: by designing a specific threshold value exclusive to a beam, the base station adjusts the number of the UEs served in the given beam and the coverage area of the given beam through the specific threshold value, thereby planning and scheduling more flexibly and efficiently.

Example 3
Embodiment 3 shows a schematic diagram of an embodiment of a radio protocol architecture for the user plane and the control plane according to the present application, 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 eNB 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 eNB 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 an eNB 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 enbs. 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 eNB 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 eNB and the UE.

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 eNB 410. The soft decisions are then decoded and deinterleaved to recover the data and control signals that were originally transmitted by the eNB410 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 UL, 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 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 eNB410, 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 eNB 410. The controller/processor 459 is also responsible for HARQ operations, retransmission of lost packets, and signaling to the eNB 410. Channel estimates derived by the channel estimator 458 from the reference signals or feedback transmitted by the eNB410 may be used by the transmit processor 468 to select appropriate coding and modulation schemes and to facilitate spatial processing. 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. The UL transmissions are processed at the eNB410 in a manner similar to that described in connection with the 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.
