Notification method of random access initiating, notification method of random access resource, and main base station

Abstract

The embodiment of the invention relates to a notification method of random access initiating, a notification method of a random access resource, a notification method of a data transmission resource, and a main base station. The notification method of the random access initiating comprises the steps that the main base station receives first notification information from source equipment; the first notification information indicates data of the source equipment to be transmitted to target equipment; the main base station sends second notification information to the target equipment; and the second notification information indicates the target equipment to initiate random access to the source equipment. With the adoption of the notification methods and the main base station, physical downlink control channel commands on various base stations are prevented from being monitored by user equipment.

Description

technical field [0001] The present invention relates to the field of mobile communication, in particular to a method for notifying initiation of random access, a method for notifying random access resources, a method for notifying data transmission resources and a main base station. Background technique [0002] With the development of the mobile communication system, in the mobile communication system, for example, a long term evolution (Long term evolution, LTE for short) system, a carrier aggregation (Carrier Aggregation, CA for short) technology is introduced. Carrier aggregation means that a user equipment (User Equipment, UE for short) can simultaneously use multiple component carriers (Component Carrier, CC for short) for uplink and downlink communication, thereby supporting higher-speed data transmission. According to the base station to which the aggregated carrier belongs, the carrier aggregation can be divided into intra-base station cell aggregation, inter-base s...

Problems solved by technology

[0007] However, in the above scheme, due to competing RAs, the preamble code (preambl) in its message 1 (msg1) is selected by the UE itself, and other UEs may send the same preamble code at the same time, resulting in conflict

Therefore, the above solution will lead to too many competing RAs, resulting in an increase in the probability of RA conflicts and unnecessary consumption of system resources.
