Description

Method and device used in user equipment and base station for wireless communication

Technical Field

The present application relates to a transmission method and apparatus in a wireless communication system, and more particularly, to a transmission method and apparatus in a narrowband internet of things system.

Background

In a conventional 3 GPP-3 rd Generation Partner Project (3 GPP-3 rd Generation Partner Project) Long Term Evolution (LTE-Long Term Evolution) system, a base station may transmit DCI (Downlink control information) for scheduling different CCs (Component carriers) in one CC through Cross Carrier scheduling (Cross Carrier scheduling), and candidates (candidates) corresponding to the DCI for scheduling different carriers often occupy different time-frequency resources in the CC in order to avoid collision between DCIs for scheduling different carriers.

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 the bandwidth of about 180KHz is consumed, and the NB-IoT can be directly deployed in a traditional network so as to reduce the deployment cost and realize smooth upgrade. NB-IoT was first introduced in 3GPP Rel-13, and the NB-IoT system of Rel-13 was enhanced in 3GPP Rel-14. In Rel-13 and Rel-14, the transmission of NB-IOT does not support scheduling across narrow bands, i.e., NPDCCH (Narrowband Physical Downlink Control Channel) and the data Channel scheduled by NPDCCH are both transmitted in one narrow band. 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, introduction of Cross-Narrowband (Cross Narrowband) scheduling is also considered in Rel-15.

Disclosure of Invention

When the NB-IOT system supports cross-narrowband scheduling, a simple implementation is to add a CIF (Carrier Indicator Field) Field similar to the existing system in the DCI to indicate the frequency domain position of the narrowband occupied by the scheduled data, and fix the narrowband for transmitting NPDCCH. However, one disadvantage of this method is that the narrowband used for transmitting NPDCCH lacks flexibility and there is a serious collision problem on the narrowband on which NPDCCH is transmitted.

Based on the above problems and analysis, the present application discloses a solution. Without conflict, embodiments and features in embodiments in the user equipment of the present application may be applied to the base station and vice versa. The embodiments and features of the embodiments of the present application may be combined with each other arbitrarily without conflict.

Fig. 3 is a schematic diagram illustrating an embodiment of a radio protocol architecture for the user plane and the control plane, fig. 3 showing the radio protocol architecture for the User Equipment (UE) and the base station equipment (gNB or 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 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 Protocol) 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-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 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 (Hybrid Automatic Repeat reQuest). 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). 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.
