Embodiment Construction

[0026] Those skilled in the art will recognize and understand that the details of the described examples are only illustrations of some embodiments, and the teachings explained in this application are applicable to various alternative settings.

[0027] Please refer to figure 1 , figure 1 An example of part of a cellular communication system in operation according to an embodiment of the present invention is shown. Wherein, the cellular communication system is generally represented as 100 and includes an evolved Node B (eNB) 101; the eNB supports an LTE cell 102. In other embodiments, the eNB 101 may support multiple cells. The eNB 101 includes a part of a radio access network (E-UTRAN in this example). The user equipments 103a, 103b, and 103c are all located in the coverage area of ​​the cell 102. in figure 1 Only 3 user equipments are shown in, however, more or fewer user equipments can also be set in the cell 102, and these user equipments are in the connected mode at any gi...

Abstract

A method and apparatus suitable for Long Term Evolution cellular communication systems (100) are provided which identify spare, unused PUCCH (Physical Uplink Control Channel) resources which can be used by User Equipment (103a, 103b, 103c) for Scheduling Requests for data transmission. An evolved NodeB (101) can signal the availability of such resources to UE using a PHICH (Physical Hybrid Activation Repeat Request Channel) or with Downlink Control Information (DCI).

Description

Technical field [0001] The embodiments of the present invention generally relate to cellular communication systems, and in particular, to devices and methods for determining the configuration of scheduling request opportunities. Background technique [0002] Cellular communication systems, such as third-generation (3G) mobile phone standards and technologies are well known. This 3G standard and technology was developed by the third-generation partner project. The third generation of wireless communications has been extensively developed to support macro cell mobile phone communications. This kind of macro cell uses a high-power base station (NodeB (NodeB)) to communicate with wireless communication units in a larger geographic coverage area. Generally speaking, a wireless communication unit, or user equipment (User Equipment, UE) commonly referred to as a user equipment, communicates with a core network (Core Network, CN) of a 3G wireless communication system through a radio ne...
