Embodiments herein relate to a method, performed by a network node () in a wireless communication system (), for handling resource allocations for a first User Equipment, UE () out of a set of UEs (). Each of the UEs () in the set of UEs() has a different pre-configured frequency allocation for cyclic transmissions, such as cyclic UL and/or DL transmissions. The network node () determines, based on a data arrival pattern, such as e.g. a packet arrival time, of the cyclic UL transmissions for each of the UEs in the set of UEs (), one or more TTIs, where a collision between transmissions to and/or from two UEs () out of the set of UEs () may occur. The 10 network node () reconfigures the frequency allocation for a first UE () of the two UEs () to overlap, at least partly, with the frequency of a second UE () of the two UEs () for the TTIs other than the TTIs where the collision between the transmissions to and/or from the first and the second UEs () may occur. Embodiments herein further relate to a method, performed by the first UE () out of the set of UEs () in 15 the wireless communication system (), for handling resource allocation for the first UE () out of the set of UEs ().

Network node, user equipment and methods performed therein in a wireless communications network

The present invention relates to a power headroom control element for communicating power information from a user equipment (UE) to a base station (BS), a corresponding method, a method for processing received power information at a radio access network (RAN) as well as to a user equipment for communicating power information and a base station configured to process received power information, which particularly enable simple handling and processing of transmission power information, respectively. A power headroom control element is structured to comprise a power headroom field containing power headroom information and having a predetermined number of bits in the power headroom control element, and an indicator field associated with the power headroom field, wherein the indicator field serves to indicate whether a transmission power field with a predetermined number of bits is present in the power headroom control element.

Power headroom control element, method of communicating power information from a user equipment, method for processing received power information as well as a corresponding user equipment and base station

A method performed by a base station includes determining a reliability requirement for a packet to be transmitted to a wireless device. The reliability requirement is determined based at least in part on a consecutive packet loss associated with at least one previously transmitted packet. Based on the reliability requirement, the packet is transmitted to the wireless device.

An apparatus, system and method are introduced for controlling a user equipment in a first network with a resource control server. In one embodiment, the resource control server provides instructions over the second network to the user equipment of actions to be taken based at least in part on congestion within the first network.

System and method for congestion control in a communication system

A method for message control in a cooperative intelligent transport system comprises creating (S) of a transmission restriction control message. The transmission restriction control message comprises restriction instructions, defining how a transmission restriction demand is to be applied by an on board unit, and validity information. The transmission restriction control message is broadcasted (S). A method for message control in a cooperative intelligent transport system comprises receiving, in an on board unit, a transmission restriction control message. The transmission restriction control message comprises restriction instructions, defining how a transmission restriction demand is to be applied by the on board unit, and validity information. It is determined whether or not the on board unit fulfils the validity information. If the on board unit fulfils the validity information, the transmissions of messages from the on board unit are adapted according to the restriction instructions. Corresponding apparatuses are also disclosed.

Intelligent transport system message control method and arrangement

A method for communication within a cooperative intelligent transport system. The method comprises receiving, in a first node, a first intelligent transport system message from another node of the cooperative intelligent transport system. In the first node, a technology status of that another node is identified. The technology status comprises information whether or not the first intelligent transport system message was transmitted configured according to a predetermined first intelligent transport system technology, and information whether or not the first intelligent transport system message comprises a dual technology indicator. The dual technology indicator is an information element identifying that the node transmitting the first intelligent transport system message is capable of communicating intelligent transport system messages according to the first intelligent transport system technology as well as according to a predetermined second technology. A corresponding node for communication within a cooperative intelligent transport system is also disclosed.

Methods and arrangements in a telecommunication system

The present disclosure relates to a method () in a first radio access node for obtaining neighboring cell information. The method comprises the steps of transmitting via an interface a radio access node request (Si) for set-up information related to the neighboring cell to at least one second radio access node, and receiving a radio access node response (Si) over the interface from said at least one second radio access node. The radio access node response (Si) comprises set-up information including an indicator related to the neighboring cell's capability for uplink transmission. The present disclosure also relates to said first radio access node.

Methods in a radio access node for obtaining neighbouring information and radio access nodes

Systems and methods for Secondary Cell (sCell) selection for wireless devices operating according to a carrier aggregation scheme in a cellular communications network are disclosed. In one embodiment, a network node in the cellular communications network obtains geographic signatures for a number of candidate sCells. The geographic signatures include a geographic signature for each candidate sCell that approximates a coverage area of the candidate sCell. The network node obtains position information for a wireless device and then selects one or more sCells for the wireless device from the candidate sCells based on the geographic signatures for the candidate sCells and the position information for the wireless device. The network node then configures the selected sCell(s) for use by the wireless device according to a carrier aggregation scheme. Using this process, sCell selection is performed, in some examples, without measurement gaps and without disabling an s-Measure parameter.

A network node (), a wireless device () and methods for controlling a radio communication using carrier aggregation. The wireless device () sends () UE capabilities to the network node (), indicating a maximum capability limit per component carrier and a total maximum capability limit across all component carriers to be used in the radio communication. The network node () further selects () a number of component carriers to be used by the wireless device, and configures () radio features on the selected component carriers based on the received UE capabilities. The network node () then signals () the selected number of component carriers and the configured radio features to the wireless device () for use in the radio communication (). Thereby, the network node () can utilize the full capabilities of the wireless device () when configuring the radio features while still respecting both the maximum capability limit per carrier and the total maximum capability limit.

Systems and methods for Secondary Cell (sCell) selection for wireless devices operating according to a carrier aggregation scheme in a cellular communications network are disclosed. In one embodiment, a network node obtains a list of potential sCells for a wireless device. The network node blindly selects an sCell for the wireless device from the list of potential sCells. The network node then configures the wireless device with the selected sCell. Blindly selecting the sCell for the wireless device makes it possible to avoid the use of measurement gaps and reduce throughput loss, according to some embodiments.
