Problems solved by technology

[0007] However, use of such persistent grants may lead to inefficient use of UL radio resources
Specifically, there may be situations where UL radio resources are allocated to a UE, but the UE has no UL data to transmit, i.e., the UE is over-allocated with UL radio resources
Such over-allocated UL radio resources will not be available for other purposes and thus be wasted

Embodiment Construction

[0027] Hereinafter, concepts according to exemplary embodiments of the present invention will be explained in more detail with reference to the accompanying drawings. The illustrated embodiments relate to concepts for controlling radio transmissions in a cellular network. Embodiments relate in particular to scenarios utilizing LTE radio access technology. However, it should be understood that the concepts can also be applied in conjunction with other radio access technologies such as the Universal Mobile Telecommunications System (UMTS) radio access technology.

[0028] According to the concept shown, UL transmissions from a communication device to a cellular network are performed on UL radio resources that can be allocated by two types of UL grants: first UL grants, which are hereinafter referred to as IUA-UL grants (IUA: Instantaneous UL access), which each indicate the radio resources allocated to the communication device in the recurring time interval; and the second UL gra...

Abstract

An access node (100) of a cellular network sends an uplink grant to a communication device (10-A, 10-B, 10-C). The uplink grant indicates an uplink radio resource allocated to a communication device (10-A, 10-B, 10-C) in a recurring time interval. The access node (100) monitors each of the previously configured uplink radio resources in the recurring time intervals to obtain information transmitted by uplink transmissions on the indicated uplink radio resources in the corresponding recurring time interval An indication of the intent of the uplink data. In response to detecting no indication and determining that an uplink transmission is required by the further communication means (10‑A, 10‑B, 10‑C) in the corresponding recurring time interval, the access node (100) will correspond to The indicated uplink radio resources in the time interval are reallocated to the further communication device.

Description

technical field [0001] The invention relates to a method and a corresponding arrangement for controlling radio transmissions in a cellular network. Background technique [0002] In cellular networks, the allocation of radio resources to a certain user equipment (UE) is usually implemented dynamically on the network side (this is also called scheduling). In the downlink (DL) direction from the cellular network to the UE, the network node may allocate radio resources as needed in order to transmit DL data to the UE. The network node may then inform the UE about the allocated resources by sending a DL assignment. For the uplink (UL) direction from the UE to the cellular network, a scheduling request sent by the UE to the cellular network may be used to indicate that the UE needs radio resources for sending UL data. For example, in LTE (Long Term Evolution) radio access technology specified by 3GPP (3rd Generation Partnership Project), a base station of LTE radio access techno...
