Problems solved by technology

During the above ambiguity period, the base station cannot determine when the UE completes the reception and analysis of the preset RRC message
If the UE has not successfully switched to BWP2, the base station has canceled scheduling UE on BWP1 and started scheduling UE on BWP2, which may cause transmission loss
Or, the target UE has successfully switched to BWP2, but the base station still schedules the UE on BWP1, which will also cause transmission loss and affect the user experience of 5G network equipment

Embodiment approach

[0172] Mode 1: If the successful reception message sent by the target UE is received, start scheduling the target UE on the second BWP, and stop scheduling the target UE on the first BWP after a first preset waiting period.

[0173] In the embodiment of the present disclosure, considering that after the target UE receives the BWP switching information, it will take a certain amount of time to parse the information and complete the process of configuring the scheduling control information of the second BWP according to the activation control information in the BWP switching information, Therefore, after receiving the successful reception message, the base station starts to schedule the target UE on the second BWP, and stops scheduling the target UE on the first BWP after a first preset waiting period. Wherein, the aforementioned preset waiting period may be a period determined by the base station according to historical experience, such as a transmission time interval TTI.

Abstract

Provided are a method for information transmission adjustment, a base station, and user equipment, said method comprising: by means of an upper layer message, sending BWP handover information to a target UE, said BWP handover information being used for instructing said target UE to switch current bearer information transmission from a first BWP to a second BWP; monitoring the preset uplink feedback information of the target UE, said preset uplink feedback information being used for indicating that the target UE has received and / or parsed said BWP handover information; if said preset uplink feedback information has been received, then stopping scheduling of the target UE on the first BWP. When a base station upper layer message instructs a UE to switch BWPs, the information transmission adjustment method of the present disclosure ensures that during the handover process, the UE will not experience information transmission loss, thus effectively enhancing the reliability of information transmission during a BWP handover process.

Description

technical field [0001] The present disclosure relates to the field of communication technologies, and in particular to a method for adjusting information transmission, a base station and user equipment. Background technique [0002] 5G NR (New Radio) can be deployed in the high-frequency range from 3.3GHz to 24GHz, so the frequency range of each carrier in the 5G NR system may be larger than the frequency range of each carrier in the 4G LTE (Long Term Evoluttion, long-term evolution) system a lot of. In a 5G network, the bandwidth of a single frequency band will be close to 1GHz, and the bandwidth level of a single carrier will be between 80MHz and 400MHz. In consideration of energy saving of a UE (User Equipment, user equipment) in a 5G network, a single carrier may be divided into multiple BWPs (Band Width Part, bandwidth segments). The base station can schedule UEs on one or more BWPs. [0003] Taking the base station currently scheduling UE on a BWP such as BWP1 as an...
