Problems solved by technology

If the existing technology is used to perform out-of-synchronization processing on the UE, some UEs with carriers in the out-of-synchronization state will be caused. Even if some carriers are still in the synchronous state, the data transmission of the entire UE will still be interrupted, making available resources unavailable. cause waste of transmission resources

Embodiment 1

[0055] Embodiment 1: The uplink feedback positions corresponding to all downlink carriers in the TA Group of the secondary cell are configured on the PUCCH corresponding to the uplink carrier of the primary cell, the TA Group of the secondary cell is out of synchronization, and the TA Group to which the primary cell belongs is still in a synchronized state. In this case, the UE's data processing includes:

[0056] The UE receives the configuration from the base station and reads the configuration information about the PUCCH, where the PUCCH is only configured on the uplink carrier of the primary cell, that is, the corresponding uplink feedback of all downlink carriers in the TA Group of the secondary cell is sent on the uplink carrier of the primary cell.

[0057] Under the control of the base station, the UE maintains the uplink synchronization of the TA Group to which the primary cell belongs and the TA Group of the secondary cell respectively.

[0058] After a period of tim...

Embodiment 2

[0064] Embodiment 2: The corresponding uplink feedback positions of the downlink carriers in the TA Group of the secondary cell are all configured on the PUCCH corresponding to the uplink carrier in the current TA Group, and the TA Group of the secondary cell is out of synchronization. In this case, the UE's data processing includes:

[0065] The UE receives the configuration on the base station side and reads the configuration information about the PUCCH, wherein the corresponding uplink feedback of the downlink carrier in the TAGroup of the secondary cell is sent on the uplink carrier PUCCH of the TA Group.

[0066] Under the control of the base station, the UE respectively maintains the uplink synchronization of the TA Group to which the primary cell belongs and the TAGroup of the secondary cell.

[0067] After a period of time, the UE does not receive the uplink timing advance information about the secondary cell sent by the base station, causing the TA timer corresponding...

Embodiment 3

[0073] Embodiment 3: The corresponding uplink feedback positions of all downlink carriers in the TA Group of the secondary cell are configured on the PUCCH corresponding to the uplink carrier of the primary cell, and the TA Group of the primary cell is out of sync. In this case, the data processing of the UE includes:

[0074] The UE receives the configuration from the base station and reads the configuration information about the PUCCH, where the PUCCH is only configured on the uplink carrier of the primary cell, that is, the corresponding uplink feedback of all downlink carriers in the TA Group of the secondary cell is sent on the uplink carrier of the primary cell.

[0075] Under the control of the base station, the UE maintains the uplink synchronization of the TAGroup of the primary cell, and starts or restarts the TA timer related to the TA Group of the primary cell when receiving the uplink timing advance information of the primary cell from the base station.

Abstract

The invention discloses a data processing method and device, which are used for avoiding interruption of data transmission of whole UE (User Equipment) while partial carriers of the UE are in an out-of-step state so that available resources remain workable and transmission resource waste can be avoided. The data processing method provided by the invention comprises the steps of: determining corresponding states of multiple pre-divided timing advance groups TA Group, wherein the TA Group comprises a TA Group consisting of auxiliary cells of the UE and a TA Group including main cells of the UE; and processing data according to a configuration situation of an uplink feedback position corresponding to a downlink carrier in each TA Group while a TA Group in an uplink out-of-step state exists.

Description

technical field [0001] The present invention relates to the field of communication technologies, in particular to a data processing method and device. Background technique [0002] The peak rate of the advanced long-term evolution (LTE-A, LTE Advanced) system is greatly improved compared with the peak rate of the LTE system, and it is required to reach 1 Gbps in the downlink and 500 Mbps in the uplink. At the same time, the LTE-A system requires good compatibility with the LTE system. The LTE-A system introduces a carrier aggregation (CA, CarrierAggregation) technology based on the need to increase the peak rate, be compatible with the LTE system, and make full use of spectrum resources. [0003] The carrier aggregation technology refers to a mechanism in which a user equipment (UE) can aggregate multiple cells (cells) at the same time, and multiple cells can simultaneously provide data transmission services for the UE. In the carrier aggregation system, the carriers corre...
