Problems solved by technology

[0003] In the prior art, the intra-slot frequency hopping technology is used in the long PUCCH, and the structure of a typical long PUCCH is as follows figure 2 As shown, it includes a plurality of uplink control information UCI (Uplink Control Information), demodulation reference signal DMRS (Demodulation Reference Signal) and frequency hopping points. UCI and DMRS are usually arranged at intervals, and the frequency hopping point is located in the center. In certain cases, For example, when the long PUCCH occupies fewer symbols, the frequency hopping in the time slot will significantly reduce the multiplexing capacity of the UE, so continuing to use frequency hopping in this case will reduce the performance of the system. However, in the prior art, NR There is no option to enable / disable frequency hopping, and the current long PUCCH slot structure cannot effectively reduce the impact of frequency hopping

Embodiment 1

[0039] Embodiment 1 and Embodiment 2 propose a method for controlling UE to enable / disable frequency hopping, and the flow chart of Embodiment 1 is as follows image 3 As shown, this embodiment provides a method in which the access network device notifies the UE to enable / disable frequency hopping, and the specific process is as follows:

[0040] S310: The access network device constructs downlink control information;

[0041] The access network device can be any device on the access network side according to the different network architectures. Preferably, the access network device can be a gNB; the downlink control information includes information indicating that the UE enables / disables frequency hopping information, specifically, a new element / parameter / identification dedicated to instructing the UE to enable / disable frequency hopping can be set in the downlink control information, and the UE determines whether to enable / disable according to the value of the new element / par...

Embodiment 2

[0048] Embodiment 2 is another setting method proposed by the present invention. This embodiment indicates whether the UE enables / disables frequency hopping by means of high-level parameters, such as image 3 As shown, the specific process of this embodiment is as follows:

[0049] S410: Set a high-level parameter for indicating whether the UE enables / disables frequency hopping;

[0050] The high-level parameter indicating whether the UE enables / disables frequency hopping may be a newly set high-level parameter dedicated to indicating whether the UE enables / disables frequency hopping, for example, a new high-level parameter PUCCH-HoppingConfig, and the UE acquires the value of this parameter , when its value is 1, it means that frequency hopping is enabled, and when its value is 0, it means that frequency hopping is disabled. Some high-level parameters are modified to indicate whether the UE enables / disables frequency hopping.

[0051] S420: The UE sets frequency hopping acc...

Abstract

The present invention discloses a physical uplink control channel arrangement method. The method comprises the steps of: sending downlink control information to user equipment by a network device; receiving the downlink control information by the user equipment, and arranging the frequency hopping according to the downlink control information; or arranging high-level parameters configured to indicate the user equipment to start / stop frequency hopping; and arranging the frequency hopping by the user equipment according to the high-level parameters, and sending uplink control information to thenetwork device by the user equipment. When the frequency hopping possibly reduces the reuse capacity of the user. the physical uplink control channel arrangement method and the user equipment can pause the frequency hopping, and can restart the frequency hopping when the frequency hopping has little influence on the system performances so as to solve the problem that the frequency hopping obviously reduce the user reuse capacity in special conditions in the prior art.

Description

technical field [0001] The present invention relates to communication technology, and more specifically, to a method for setting a physical uplink control channel and user equipment. Background technique [0002] With the development of mobile communication and mobile Internet technology, the demand for data traffic has grown rapidly, and a large number of new services and requirements have emerged, such as big data services, cloud-based services, autonomous driving services, and Internet of Things services. In order to meet the needs of these services The demand requires network providers to provide larger connections, wider bandwidth, lower latency and more reliable networks than existing networks. Therefore, a new network system architecture, namely 5G system, is proposed. New air interface NR (New Radio) is the air interface technology of the 5G system. In NR, the UE sends uplink control information UCI to the access network device through the physical uplink control cha...
