Description
Technical Field
The present invention relates to the field of mobile communications technologies, and in particular, to a method for acquiring base station resources, a terminal, and a base station.
Background
Currently, in the field of mobile communication, a Carrier Aggregation (CA) solution of LTE (Long Term Evolution) is mainly used to solve the problem of spectrum discontinuity of an operator, and can improve the throughput of a communication system. Carrier aggregation, i.e. aggregation of multiple continuous or discontinuous component carriers, obtains a larger transmission bandwidth, thereby obtaining a higher peak rate and throughput.
For the communication protocol of Rel-10 version, the use of two carriers is the most typical scenario, in which two PUCCH (Physical Uplink Control CHannel) CHannel formats are introduced: the band channel selects Format1b and Format 3.
In practical application, the Format1b with channel selection can feed back at most 4-bit effective a/N (ACK/NACK, acknowledge/not acknowledge) information, and the Format3 can feed back 20-bit effective information, so that the traffic yield is the maximum when the User Equipment (UE) uses the Format of Format3 and the base station is configured with resources of the relevant Format 3.
However, according to the current protocol, the base station side cannot know whether the UE supports Format3, and because the number of UEs supporting Format3 is less than that of UEs supporting Format1b, the base station generally issues the configuration channel by default to be selected as Format1b, which results in a large reduction in the performance of the UEs supporting Format3 and negative user perception.
