Methods of operating an electronic device are provided. A method of operating a first electronic device includes listening for a wireless transmission by a second electronic device on a wireless communications channel. The method includes determining whether a packet is a particular type of packet. The method includes assigning a randomized time delay value that defines a randomized delay period, in response to determining that the packet is the particular type of packet. The method includes beginning the randomized delay period in response to determining that the wireless communications channel is clear. Moreover, the method includes transmitting the packet via the wireless communications channel based on expiration of the randomized delay period. Related electronic devices and computer program products are also provided.

Transmitting a packet via a wireless local area network after a delay

The present invention relates to a communication device and to a method each of them being configured to: divide data to be transmitted into at least one data portion; and transmit each data portion during a time, at which the device is to be activated for executing a pre-determined activity, wherein the pre-determined activity comprises at least one corresponding data and/or signal communication and wherein the transmission of the data portion refers to a further activity of the communication device that is different from the pre-determined activity.

Communication device and method for transmitting data

A radio device () detects a trigger event, which may for example correspond to receiving a paging message (). In response to the trigger event, the radio device () monitors radio channel quality experienced by the radio device (). In response to a condition based on the monitored radio channel quality channel being met, the radio device triggers a data transfer with the cellular network.

A control message is indicative of a timing parameter of a slotted transmission () comprising active slots () and inactive slots (). At least one repetition () of data () is transmitted in an active slot on a wireless link.

Slotted transmission for battery recovery

The one or more processors of an electronic device execute program code. While executing the program code, measurements are performed on the electronic device to obtain first data. Further, execution of the program code is monitored to obtain second data, e.g., debug information. The measurements are coordinated with the monitoring of the execution of the program code.

A plurality of payload messages () is communicated on a radio link of a cellular network between a terminal () and an access node () of the cellular network. Each one of the plurality of payload messages () includes a data packet () encoded according to a given redundancy version (-). The number of the plurality of payload messages () may be dynamically and flexibly adjusted in some embodiments. Examples are given which may be applied for coverage enhancement in the Internet of Things or Machine Type Communication domain.

Dynamic coverage enhancement

A plurality of payload messages is communicated on a radio link of a cellular network between a terminal and an access node of the cellular network. Each one of the plurality of payload messages includes a data packet encoded according to a given redundancy version. The number of the plurality of payload messages may be dynamically and flexibly adjusted in some embodiments. Examples are given which may be applied for coverage enhancement in the Internet of Things or Machine Type Communication domain.

A mobile communication network comprises a first cell () and a second cell () arranged in a coverage area of the first cell (). A node () of the mobile communication network obtains positioning data of a UE (). The node () correlates the positioning data to a coverage area of the second cell (). Depending on the correlation of the positioning data and the coverage area of the second cell (), the node () selects between an active state and an inactive state of the second cell (). In accordance with the selected state, the node controls a base station of the second cell ().

Positioning data based cell management

First reoccurring resources on a radio link of a cellular network are allocated to the first relaying channel. Second reoccurring resources on the radio link are allocated to a second relaying channel. The first reoccurring resources are shared between communication devices assigned to a first set; the second reoccurring resources are shared between communication devices assigned to a second set. The first reoccurring resources, in some embodiments, may be orthogonal to the second reoccurring resources.

A cellular multiple-input and multiple-output, MIMO, system comprises a base station having a plurality of antennas. Pilot signals are received by the base station in each frame of a sequence of frames (). The base station analyzes the pilot signals to determine radio channel properties of radio channels between respectively each one of a plurality of terminals and the base station. The sequence of frames () comprises frames of a first frame type () and frames of a second frame type (). Each frame of the second frame type () have a greater number of time slots in which the base station receives the pilot signals than each frame of the first frame type (). The frames of the second frame type () are included periodically in the sequence of frames ().

The invention is directed to systems, methods and computer program products for discontinuous signaling in a mobile communication network. User equipment (UE)/mobile terminal requests slotted transmissions and, in response to the network authorizing slotted transmissions, communication of subsequent UE transmissions are slotted, such that a minimum time period is required to elapse between each UE transmission. In specific embodiments of the invention the minimum time period is a predetermined time period known in advance to the user equipment and network. In other embodiments of the invention the user equipment slotted transmission requests includes a requested minimum time period, which may be approved or revised by the network. In still further embodiments the network, upon receiving the request for slotted transmissions, determines the minimum time period.
