Embodiment Construction
[0153] The following will clearly and completely describe the technical solution in this embodiment with reference to the drawings in this embodiment. Obviously, the described embodiment is only a part of the embodiments of the present invention, but not all of them. Based on the embodiments of the present invention, all other embodiments obtained by persons of ordinary skill in the art without creative efforts fall within the protection scope of the present invention.
[0154] In order to improve the reception quality of the uplink control channel of the macro station in the heterogeneous network, this embodiment provides a method for improving the quality of the uplink channel in the heterogeneous network. This method is mainly applied to the UE side. Quantitatively calculate the adjustment amount of the transmission power by the uplink and downlink imbalance, and improve the reception quality of the uplink control channel of the macro station by increasing the uplink transmi...

The invention discloses a method, device and user equipment (UE) for improving the quality of an uplink channel in a heterogeneous network, relates to the field of communication technology, and is invented for solving the problem of poor reception quality of uplink channels of macro stations in unbalanced areas. The method of the present invention includes: the UE obtains the uplink and downlink imbalance degree, calculates the transmission power adjustment amount of the UE according to the uplink and downlink imbalance degree, and adjusts the transmission power of the uplink control channel according to the transmission power adjustment amount; another method of the present invention includes : The user equipment UE obtains the uplink and downlink imbalance degree, and calculates the fallback value according to the uplink and downlink imbalance degree. There is a positive correlation between the fallback value and the uplink and downlink imbalance degree, and the fallback value is used to indicate the reduction of the transmission block length , adjust the transport block length of the uplink data channel according to the backoff value. The present invention is mainly applied in the process of UE performing soft handover in an unbalanced area.
Description
technical field [0001] The present invention relates to the field of communication technologies, and in particular to a method, device and user equipment (User Equipment, UE for short) for improving uplink channel quality in a heterogeneous network. Background technique [0002] The traditional wireless access network mainly refers to the homogeneous network (HomoNet for short). In the homogeneous network, each base station has the same downlink transmission power and roughly the same cell coverage. Coverage, providing uninterrupted communication services for UEs. With the continuous development of communication technology and the further refinement of communication service scenarios, in order to better meet the needs of different users, a heterogeneous network (Heterogeneous Network, HetNet for short) has emerged, the third generation of mobile communication technology ( Wide band Code Division Multiple Access (WCDMA) in 3rd-Generation (referred to as 3G) uses heterogeneou...
