Embodiment Construction

[0061] In the following, embodiments will be described in which the required transmission loss (eg power and / or energy) is estimated if data is to be transmitted by the transceiver. The required transmission loss is used to determine whether a data transmission should be initiated or a decision on data transmission should be postponed.

[0062] Embodiments discussed herein are particularly useful when the data to be transmitted does not require high quality of service (QoS), eg in the sense of high data rate transmission and / or low latency / real time transmission.

[0063] These embodiments are also particularly advantageous for applications where transmission is performed under (more or less severe) power consumption and / or energy consumption constraints.

[0064] In schemes based only on current conditions, transmissions are typically made when the channel is good enough (eg, based on a threshold). However, in some scenarios, the channel may be better at a future moment. Th...

Abstract

A method of controlling data transmission by a transceiver is disclosed. The method includes determining that data is to be transmitted by the transceiver, and receiving the signal. A current required transmission loss for data transmission is estimated based on the received signal, and whether to initiate data transmission is determined based on the estimated current required transmission loss, required transmission loss statistics, and time criteria associated with the data. If it is determined that data transmission should be initiated, data transmission is initiated, otherwise the decision to transmit data is postponed. Corresponding computer program products, processors, apparatus and wireless communication devices are also disclosed.

Description

technical field [0001] The present invention relates generally to the field of control of data transmissions. More specifically, the present invention relates to the control of data transmission in power and / or energy constrained applications. Background technique [0002] In wireless communications, the success of a data transmission is often related to the power and / or energy used for the transmission. For example, a data message sent using high power generally has a greater probability of reaching an intended receiver in a detectable and readable condition than the same data message sent using lower power. [0003] On the other hand, in a multi-user system it is often beneficial if not to transmit using more power than necessary. [0004] Therefore, there are usually intervals or precise values ​​relating to the transmit power that a particular transmitting unit should preferably use. This interval or value can generally vary over time. For example, the change may be ...
