- -application number of the original application: 201710903423.8

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 invention relates to a transmission method and apparatus in a wireless communication system, and more particularly, to a transmission method and apparatus of a wireless signal supporting BWP (Bandwidth Part) dynamic switching.

Background

Currently, a technical discussion of 5G NR (New Radio Access Technology) is in progress. Compared with LTE (Long-Term Evolution ) and LTE-a (Long-Term Evolution Advanced, enhanced Long-Term Evolution), the concept of BWP is introduced in the 5G system, that is, when a cell has a CC (computer carrier) with a larger bandwidth, a base station can split the larger CC into a plurality of BWPs to adapt to a UE (User Equipment) with smaller receiving bandwidth and sending bandwidth capability; when the UE with smaller bandwidth capability communicates with the cell, the UE only receives downlink or uplink on one BWP. The method effectively reduces the cost of the user equipment and increases the compatibility of the system. In order to improve the configuration flexibility and real-time performance of BWP, a scheme of dynamically switching BWP by using dci (downlink Control information) including scheduling is adopted in RAN1 AH _ Hoc conference in 9 months of 2017. Accordingly, the design of the relevant DCI needs to be considered.

Disclosure of Invention

To ensure the BWP dynamic handoff implementation, RAN1#90 agreed to support an initial BWP as the start of the BWP handoff. Because the dynamic signaling itself does not have HARQ-ACK (Hybrid Automatic Repeat request-Acknowledgement) of the physical layer, a solution at present is that the dynamic switching of BWP can only be included in DCI with scheduling; when the DCI is a downlink Grant (Grant), the base station judges whether BWP dynamic switching is correctly received by the UE or not through HARQ-ACK which is fed back by the uplink and aims at downlink data; when the DCI is an uplink grant, the base station judges whether the BWP dynamic switching is correctly received by the UE or not through uplink receiving. However, the method still has the defect of low robustness due to the possibility of DCI missing detection and False Alarm (False Alarm) of the UE and the misjudgment of the ACK/NACK by the base station. Meanwhile, due to the existence of the initial BWP, the domain related to BWP handover in DCI also needs to be considered.

In view of the above, 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.

The application discloses a method used in a user equipment for wireless communication, characterized by comprising:

-detecting first signalling in a first time slot of a first frequency domain resource;

-receiving a target radio signal in a second time slot of the target frequency domain resource;

wherein the first signaling is physical layer signaling; if the first time slot belongs to a first time resource set, a first domain is absent in the first signaling, and the information related to the target frequency domain resource is configured by higher layer signaling; otherwise, the first signaling comprises a first domain, and the first domain in the first signaling indicates the information related to the target frequency domain resource; the second time slot is associated to the first time slot.

As an example, the above method has the benefits of: designing a second time resource set, wherein the second time resource set is related to the first time resource set, and a given downlink BWP detected by the UE in the second time resource set is fixed or configured through high-layer signaling, so as to ensure that the UE can still receive wireless signals on the given downlink BWP in the second time resource set if the BWP dynamic switching instruction is not correctly received by the UE or if the base station and the UE have different understanding on the BWP dynamic switching instruction, thereby improving system robustness.

As an example, another benefit of the above method is: the first time resource set is designed, because the UE only receives the fixed downlink BWP in the second time resource set associated with the first time resource set, the UE does not need to detect whether the BWP is dynamically switched in the first time resource set, and then the UE detects the first signaling in a mode without a first domain, so that the load size of the first signaling is reduced, the robustness of the first signaling is improved, and the Blind detection (Blind Decoding) times are reduced.

As an example, the above method has the benefits of: when the first signaling comprises the first domain, the UE performs dynamic switching of downlink BWP according to the first domain when receiving a target wireless signal; further, if the target wireless signal is a downlink grant, the target wireless signal does not need to switch to the downlink BWP again through the scheduling information.

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 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) sublayer 303, and a PDCP (Packet Data Convergence Protocol) sublayer 304, which terminate at the gNB on the network side.

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 an RRC (Radio Resource Control) sublayer 306 in layer 3 (layer L3).
