Embodiment Construction

[0087] The following embodiments of the present invention provide an uplink resource allocation method, a UE and a base station.

[0088] In order to enable those skilled in the art to better understand the technical solutions in the embodiments of the present invention, and to make the above-mentioned purposes, features and advantages of the embodiments of the present invention more obvious and understandable, the following describes the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings For further detailed explanation.

[0089] With the development of mobile communication technology, in order to cope with the growth of mobile data service traffic, the scenario of small cell deployment is added to the existing communication system. For example, in places where there are many UEs, cells with small coverage areas are deployed in high density. These cells can be called small cells (Small cells), and the base stations co...

Abstract

An uplink resource allocation method, a UE, and a base station, the method comprising: a user equipment UE acquires a target cell corresponding to a logical channel of an uplink service, and the target cell is in a deactivated state; the UE activates the target cell; the UE receives the target cell The cell allocates uplink transmission resources for the UE according to the identifier of the logical channel group where the logical channel is located and the amount of uplink buffered data in the logical channel group. In the embodiment of the present invention, the UE can directly activate the target cell according to the correspondence between the logical channel and the target cell, so that the base station does not need to notify the UE of the cell to be activated through an activation command such as MAC CE, thus saving system transmission resources and reducing The time delay for the UE to obtain downlink transmission resources.

Description

technical field [0001] The present invention relates to the field of communication technologies, and in particular to an uplink resource allocation method, user equipment (User Equipment, UE) and a base station. Background technique [0002] In the evolved Long Term Evolution-Advanced (LTE-A) system, the available bandwidth can be expanded for the UE through the carrier aggregation technology, that is, multiple consecutive narrower bandwidths under the same base station (eNB), or Discontinuous carriers are aggregated together. Each carrier corresponds to a cell. Among the multiple cells serving the UE, one primary serving cell (Primary Serving Cell) can be configured, and the remaining cells are secondary serving cells (Secondary Serving Cell). [0003] In the prior art, a UE transmits services with different Quality of Service (Quality of Service, QoS) requirements through different logical channels. For a UE equipped with carrier aggregation (Carrier Aggregation, CA), whe...
