摘要： Method performed by a first communication device (101) for sending downlink information to a second communication device (102). The first communication device (101) and the second communication device (102) operate in a communications network (100). The first communication device (101) determines (702) whether or not one or more third communication devices (103) operating in the communications network (100) are sending uplink information on an adjacent carrier (142). The adjacent carrier (142) is adjacent to a carrier (141) assigned to the first communication device (101) for sending the downlink information to the second communication device (102). The first communication device (101) sends (703) the downlink information to the second communication device (102) on the carrier (141) when it has determined that the one or more third communication devices (103) are not sending uplink information on the adjacent carrier (142) to the carrier (141).

摘要： A first user equipment is configured to mitigate multi-antenna inter-stream interference. A method by the first UE includes determining, based on one or more criteria, a number of multi-antenna streams whose interference can be currently mitigated by the first UE, and transmitting information based on the number of multi-antenna streams to a first network node, to a second network node, and/or to a second UE. A related method by a first network node serving or managing the first UE includes obtaining information based on a number of multi-antenna streams whose interference can be currently mitigated by a first UE at the first UE, and performing one or more radio operational tasks using the information based on the number of multi-antenna streams whose interference can be currently mitigated.

摘要： A method and system for synchronized switching of a Transmission Time Interval (TTI) between at least two different TTI length values. A UE 100 transmitting a power report, where a control node 150 or a Base Station 110A evaluates the report and decides, based on the evaluation to order the UE to switch to a different TTI length. The order message comprises the number of TTIs after which a TTI switch has to occur, composed a.o. based on radio environment condition. The UE receives a TTI switch order message and replies with a single message to its serving BS with a message to switch the TTI in a synchronous way.

摘要： Disclosed is a method performed by a network node (130) of a wireless communication network (100) for efficient usage of downlink transmission resources. The method comprises transmitting, to a wireless device (140), an encoded first control data packet on a downlink control channel using a first level of a transmission parameter, and receiving, from the wireless device (140), information on decoding status for the first control data packet transmitted on the downlink control channel using the first transmission parameter level, the decoding status being a quantitative measure of decoding complexity of the wireless device in decoding the first control data packet. The method further comprises transmitting, to the wireless device (140), an encoded second control data packet on the downlink control channel using a second level of the transmission parameter, the second level being determined based on the received information on decoding status.

摘要： Systems and methods are disclosed for utilizing unused bit resources to convey restrictions on parameters evaluated for a feedback report in a Multiple-Input Multiple-Output (MIMO) wireless communication system. In one embodiment, a method of operation of a transmitting node in a wireless network includes transmitting a feedback restriction indicator to a receiving node, where the feedback restriction indicator is an unused bit resource in one or more instances of a control channel that is indicative of one or more desired restrictions on parameters to be evaluated by the receiving node for a feedback report to be provided from the receiving node. The method of operation of the transmitting node further includes receiving the feedback report from the receiving node, where the feedback report is limited according to the feedback restriction indicator.
