Method for processing carrier activation related information, base station and UE (User Equipment)

Abstract

The embodiment of the invention provides a method for processing carrier activation related information, a base station and UE (User Equipment), wherein the method comprises the steps of obtaining the carrier activation related information by a network side, wherein the carrier activation related information comprises at least one of carrier activation information and carrier deactivation information; transmitting a physical downlink control channel (PDCCH) signaling to the user equipment (UE), wherein a default redundancy bit, a default redundancy state or a default redundancy combination of a scrambler and a state in the PDCCH signaling represents the carrier activation related information so that the UE carries out corresponding processing according to the carrier activation related information represented by the PDCCH signaling. The method, the base station and the UE, which are provided by the embodiment of the invention, completely make use of the traditional PDCCH signaling without causing extra expenses and reducing a scrambler space of the traditional PDCCH signaling, and cannot bring inconvenience to blind detection of the PDCCH without need of changing the length or structure of the traditional PDCCH signaling.

Description

technical field [0001] Embodiments of the present invention relate to the field of communication technologies, and in particular, relate to a method for processing information related to carrier activation, a base station, and user equipment (User Equipment, UE for short). Background technique [0002] In the LTE system, a base station (Evolved Node B, eNB for short) communicates and transmits data with a UE. The data transmitted by the scheduled UE in each subframe generally includes its own Physical Downlink Control Channel (PDCCH) signaling, and the PDCCH signaling carries time-frequency resource allocation information indicating the physical data channel . The UE performs corresponding processing on the PDCCH in the search space and determines its own control information, and performs further data processing according to the control information. [0003] Carrier Aggregation (Carrier Aggregation) technology is introduced in the evolved LTE system (LTE Advanced, referred...

AI Technical Summary

Problems solved by technology

[0006] The problem with the processing method of the carrier activation or deactivation information in the prior art is that: additional bits will bring additional overhead, and after the addition of bits, the length of the signaling will become longer, making the format of the signaling become complicated, which is not conducive to blind detection

The use of new scrambling codes will reduce the existing scrambling code space and have an adverse effect on the probability of false alarms
