Description

Method and device in user equipment and base station used for narrow-band communication
Technical Field
The present application relates to transmission schemes in wireless communication systems, and in particular, to a method and apparatus in a narrowband internet of things communication system.
Background
In a conventional 3 GPP-3 rd generation partnership Project (3 GPP-3 rd generation partner Project) Long Term Evolution (LTE-Long Term Evolution) system, a frame structure of a Time Division Duplex (TDD-Time Division Duplex) system is defined, some allocated subframes are used for Uplink (Uplink, UL) transmission, other subframes are used for Downlink (Downlink, DL), and switching between Downlink and Uplink occurs in a special subframe, which may be further divided into a DwPTS (Downlink Pilot Time Slot ), a GP (guard period, guard interval), and an UpPTS (Uplink Pilot Time Slot), although the DwPTS is relatively short in length with respect to a conventional subframe, it may be essentially used as a Downlink subframe for data transmission.
The narrowband Internet of Things (NB-IoT-Narrow Band Internet of Things) is an emerging technology in the IoT field, wherein the NB-IoT is constructed in a cellular network, only consumes about 180KHz of bandwidth, and can be directly deployed in a GSM network, a UMTS network or an LTE network so as to reduce the deployment cost and realize smooth upgrade. NB-IoT was first introduced in 3GPP (3rd Generation Partner Project) Rel-13, where the NB-IoT system of Rel-13 was enhanced in 3GPP Rel-14. An important enhancement aspect in Rel-14 is to give more functions to non-anchor physical resource blocks, such as supporting transmission of paging channel, supporting transmission of random access channel, etc., and introduce functions of positioning and multicast. In 3GPP Rel-15, NB-IoT is further enhanced, including reducing power consumption, enhancing measurement accuracy, introducing special scheduling requests and the like. In particular, support for TDD (Time Division Duplex) is also introduced in Rel-15.
Disclosure of Invention
In a TDDNB-IoT system, a complete downlink subframe available for a data channel and a Narrowband Physical Downlink Control Channel (NPDCCH) is limited, and thus it is very likely that the data channel and the narrowband physical downlink control channel need to be supported to transmit using a TDD special subframe.

Layer 2(L2 layer) 205 is above PHY201 and is responsible for the link between the UE and the eNB through PHY 201. In the user plane, the L2 layer 205 includes a MAC (Medium Access Control) sublayer 202, an RLC (Radio Link Control) sublayer 203, and a PDCP (Packet Data Convergence Protocol) sublayer 204, which terminate at an eNB on the network side. Although not shown, the UE may have several upper layers above the L2 layer 205, including a network layer (e.g., IP layer) that terminates at the P-GW 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 204 provides multiplexing between different radio bearers and logical channels. The PDCP sublayer 204 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 203 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 202 provides multiplexing between logical and transport channels. The MAC sublayer 202 is also responsible for allocating various radio resources (e.g., resource blocks) in one cell among the UEs. The MAC sublayer 202 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 201 and the L2 layer 205, but without header compression functions for the control plane. The Control plane also includes a RRC (Radio Resource Control) sublayer 206 in layer 3 (layer L3). The RRC sublayer 206 is responsible for obtaining radio resources (i.e., radio bearers) and configures the lower layers using RRC signaling between the eNB and the UE.

Example 3
Embodiment 3 shows a schematic diagram of an evolved node and a given user equipment according to the present application, as shown in fig. 3. Fig. 3 is a block diagram of an eNB310 in communication with a UE350 in an access network. In the DL (Downlink), upper layer packets from the core network are provided to the controller/processor 340. Controller/processor 340 implements the functionality of layer L2. In the DL, the controller/processor 340 provides header compression, ciphering, packet segmentation and reordering, multiplexing between logical and transport channels, and radio resource allocation to the UE350 based on various priority metrics. The controller/processor 340 is also responsible for HARQ operations, retransmission of lost packets, and signaling to the UE 350. The transmit processor 315 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 UE350 and mapping to signal constellation based on various modulation schemes (e.g., Binary Phase Shift Keying (BPSK), Quadrature Phase Shift Keying (QPSK)). The coded and modulated symbols are then split into parallel streams. Each stream is then mapped to multi-carrier subcarriers, multiplexed with reference signals (e.g., pilots) in the time and/or frequency domain, and then combined together using an Inverse Fast Fourier Transform (IFFT) to generate a physical channel carrying a time-domain multi-carrier symbol stream. The parallel streams are spatially pre-decoded to produce a plurality of spatial streams. Each spatial stream is then provided to a different antenna 320 via a transmitter 316. Each transmitter 316 modulates an RF carrier with a respective spatial stream for transmission. At the UE350, each receiver 356 receives a signal through its respective antenna 360. Each receiver 356 recovers information modulated onto an RF carrier and provides the information to receive processor 352. The receive processor 352 implements various signal processing functions of the L1 layer. The receive processor 352 performs spatial processing on the information to recover any spatial streams destined for the UE 350. Receive processor 352 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 310. The soft decisions are then decoded and deinterleaved to recover the data and control signals that were originally transmitted by the eNB310 on the physical channel. The data and control signals are then provided to a controller/processor 390. Controller/processor 390 implements the L2 layer. The controller/processor can be associated with a memory 380 that stores program codes and data. Memory 380 may be referred to as a computer-readable medium.
