Embodiment Construction
[0027] In order to solve the problem existing in the prior art that when the base station performs signaling reconfiguration for the UE, there is a handover blind zone of reconfiguration parameters between the base station and the UE, which leads to the failure of signaling reconfiguration between the base station and the UE and the decrease in service rate technical problem. The embodiment of the present invention provides such as image 3 A signaling reconfiguration processing method is shown, and the specific process includes:
[0028] Step 301, when the base station determines that the UE meets the signaling reconfiguration conditions, it sends a reconfiguration signaling to the UE;
[0029] Step 302, the base station determines the number of transmission times for transmitting downlink data to the UE in a multi-redundant version mode;
[0030] Step 303, the base station transmits the downlink data to the UE in a multi-redundancy version mode according to the determined ...

The invention discloses a signaling reconfiguration method and device. The method comprises steps of: issuing a reconfiguration signaling to UE when it is determined that the UE satisfies a signaling reconfiguration condition; determining the number of transmission times downlink data is transmitted to the UE in a multi-redundancy version way; transmitting the downlink data to the UE in the multi-redundancy version way according to the determined number of transmission times in order that the UE correctly receives the transmitted downlink data; and receiving a reconfiguration accomplishment signaling fed back by the UE and stopping, according to the reconfiguration accomplishment signaling, transmitting the downlink data to the UE in the multi-redundancy version way. Because the number of transmission times determined by a base station may ensure that the UE correctly receives the downlink data transmitted by the base station and the base station considers a downlink data decoding result fed back by the UE as correct reception after transmitting data to the UE the last time according to the determined number of transmission times, carrier reconfiguration failure in the prior art is prevented caused by a fact that the base station decodes the downlink data decoding result transmitted by the UE with an erroneous carrier configuration parameter.
Description
technical field [0001] Embodiments of the present invention relate to the field of communication technologies, and in particular, to a signaling reconfiguration processing method and device. Background technique [0002] Since the R8 / R9 version of LTE only uses single-carrier technology, the downlink and uplink rates are greatly limited, but people's requirements for mobile speed are getting higher and higher. The multi-carrier aggregation technology of LTE (Long Term Evolution) came into being in the R10 version. pregnancy. Carrier Aggregation (Carrier Aggregation, CA) is to aggregate two or more carrier units (Component Carrier, CC) together to obtain a larger system bandwidth (a system bandwidth of up to 100 MHz is supported). [0003] The ACK (Acknowledgment) feedback mode applicable to a single carrier only has bundling (bonding mode) and multiplex (multiplexing mode); the ACK feedback mode applicable to at least 2 carriers has added format 1b with channel selection an...
