Problems solved by technology

Therefore, the UE may not be able to adequately combine each of the independent scheduling commands sent by different cells or sectors, and therefore, may encounter a problem of degraded detection capability
Also, since the channel state may be poor, the UE may experience difficulty in detecting a signal transmitted from the base station through only one cell or sector

Embodiment Construction

[0020] Now, preferred embodiments of the present invention will be described in detail, examples of which are illustrated in the accompanying drawings. Wherever possible, the same reference numbers will be used throughout the drawings to designate the same or like parts.

[0021] An Enhanced Uplink Dedicated Channel (E-DCH) has been proposed as a channel for high-speed data transmission in the uplink direction with Node B-controlled scheduling and HARQ. Regarding Node B controlled scheduling, the E-DCH is used to send scheduling commands from the base station (Node B) to the User Equipment (UE).

[0022] For a more efficient means for sending scheduling commands, Node B controlled scheduling is implemented on top of RNC controlled scheduling. As mentioned above, RNC-controlled scheduling is less efficient than Node B-controlled scheduling.

[0023] Scheduling commands formulated at Node B can be scheduled according to rate as well as time and rate. Scheduling schemes are no...

Abstract

A method of transmitting a scheduling command during handover is disclosed. More specifically, the scheduling command is transmitted to a user equipment from a base station having a plurality of cells. In operation, the base station composes the scheduling command and transmits the scheduling command to the user equipment via at least one of the plurality of cells.

Description

technical field [0001] The present invention relates to a method for sending a scheduling command, and more particularly, the present invention relates to a method for sending a scheduling command for an uplink Enhanced Dedicated Channel (E-DCH) during handover. Background technique [0002] Currently, in a mobile communication system, various methods are studied to improve uplink transmission capability, for example, Node B-controlled scheduling, hybrid automatic repeat request (HARQ). [0003] Conventionally, the RNC sends a Transport Format Combination Set (TFCS) to the User Equipment (UE). Here, TFCS specifies a set of Transport Format Combinations (TFCs) for user equipment to select. The UE manages the arrangement of each TFC. In other words, TFCs whose required transmit power exceeds the maximum transmit power provided by the UE are excluded from the range of allowable TFCs. However, if the required transmission power of the excluded TFCs changes to fall within the ...
