Problems solved by technology

[0004] In related technologies, the method of adjusting the BWP above is to deactivate the current BWP, and then activate a new narrow-bandwidth BWP. Since the transmission control information of the new BWP needs to be reconfigured, it takes a long conversion time, resulting in transmission delay. increase, affecting the user experience of 5G network equipment

Embodiment approach

[0281] In a first implementation manner, according to the time-frequency positions of one or more target CORESETs included in the control resource adjustment information, search for its own downlink control information from the control resource regions corresponding to one or more target CORESETs. Such as Figure 6-1 As shown, the DCI belonging to itself is searched in the target CORESET, that is, the second CORESET.

[0282] In a second implementation manner, according to the time-frequency positions of one or more target control resource regions included in the control resource adjustment information, search for its own downlink control information from the control resource regions corresponding to one or more partial regions of the CORESET. Such as Figure 6-2 As shown, it searches for its own DCI within the time-frequency range (f12-f22, t1-t2).

[0283] If the above-mentioned control resource adjustment information also includes: the binding number of the search resourc...

Abstract

The invention provides a method of regulating information transmission, a base station, and a user device. The method includes: determining control resource adjsutment information aiming to a target user equipment, wherein the control resource adjsutment information is formed from control resource information adjusted on the basis of original adjustment; sending the control resource adjsutment information to the target user equipment, so that the target user equipment can monitor downlink control information in a time-frequency range belonging to adjsuted control resource; according to hte control resource adjsutment information and the range of time-frequency resources of the original schedule, distributing transmission resources to the target user equipment, wherein frequency of the transmission resources at least includes the frequency range of the adjusted control resource; and perfomring information transmission among the target user equipment through the transmission resources. The method can improve schedule adjustment efficeincy and reduce tranmission time delay due to schedule adjustment.

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] Most of the frequencies deployed by 5G NR (New Radio) are in higher frequency ranges, and may be deployed from 3.3GHz to 24GHz. Therefore, the frequency range of each carrier in the 5G NR system may be higher than that of 4G LTE (Long Term Evoluttion, long-term Evolved) the frequency range of each carrier in the system is much larger. 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. For the consideration of energy saving of UE (User Equipment, user equipment) in the 5G network, a single carrier can be divided into multiple BWPs (Band Width Part, bandwidth segment), and UEs are scheduled on one or more BWPs. [0003] The base station can...
