Embodiment Construction

[0045] In order to make the objectives, technical solutions and advantages of the present invention more clearly understood, the present invention will be further described in detail below with reference to the accompanying drawings and examples.

[0046] In order to solve the problems existing in the prior art, a brand-new downlink control information processing scheme is proposed in the present invention. On the basis of ensuring that the total number of bits carried by the original downlink control information remains unchanged, a special pattern is set to indicate that this downlink control information is a kind of downlink control information carried on the new downlink control channel format, and the control information is added. Type field, which indicates what type of control information the downlink control information carries this time, and changes the bit mapping mode of the carried control information.

[0047] The specific implementation includes: the NodeB sets t...

Abstract

The invention discloses a downlink control information processing method, which comprises that: user equipment (UE) receives the downlink control information of a base station (NodeB) and judges whether the downlink control information carries special patterns; if so, control information types carried in the downlink control information are acquired by reading control information type domains carried in the downlink control information, and the control information is read according to a corresponding mode. The invention also discloses a downlink control information processing system, base station equipment and terminal equipment. The method, the system and the equipment can reduce the processing overhead and battery consumption of the UE, and reduce the complexity of implementing the UE.

Description

technical field [0001] The present invention relates to mobile communication technology, in particular to a downlink control information processing method and system, base station equipment and terminal equipment. Background technique [0002] In the process of discussing the enhanced version of the Time Division Duplex (TDD) High Speed ​​Packet Access (HSPA+) system enhancement technology, the downlink control channels, such as the High Speed ​​Shared Control Channel (HS-SCCH) and the Enhanced Dedicated Transport Channel (E- DCH) Absolute Grant Channel (E-AGCH) and other structures need to be modified. [0003] For example, the control information carried by the HS-SCCH channel overhead reduction (HS-SCCHless) operation in the persistent packet access (CPC) will be different from the traditional HS-SCCH channel during data retransmission, so it is necessary to define A new downlink control channel format; in addition, CPC and the enhanced cell fast access state (CELL-FACH)...
