  • Patent number: 10256964
    Abstract: A method for transmitting UCI, UE and base station. The method for transmitting includes: mapping, by UE, UCI onto time-frequency resources, wherein a subframe where the UCI is located contains one uplink reference signal or contains no an uplink reference signal; and transmitting the UCI to a base station via a PUSCH. An uplink reference signal occupies only one OFDM symbol or occupies no an OFDM symbol in a subframe, which may reduce waste of resources, and correspondingly change resource mapping of the UCI, thereby obtaining better decoding performance.

  • Patent number: 10193777
    Abstract: A method and apparatus for maintaining network connectivity over power lines is disclosed. Such network connectivity is maintained even if various customers are covered by different power line networks or if one or more power lines in a network are unavailable to transmit data. More particularly, in order to bridge a gap in a power line network, one or more messages are extracted from a first node in a power line network and are then transmitted to a second node via free space transmission, illustratively wireless radio frequency (RF) transmission conforming to one or more of the 802.11a, b or g standards. When those messages are received at the second node, the message is injected back into the power line on the other side of a gap in power line coverage. This method of transmission backup will continue until power line connectivity is restore upon which the preferred method will be selected and used.

  • Patent number: 10172034
    Abstract: Method and communication network node for enabling a radio base station to adjust a Radio Access Network, RAN, capability within a RAN, such as handover or scheduling, dependent on a data transport characteristics of a backhaul network, such as data transfer rate, network delay and bandwidth. The RAN and the backhaul network are parts of a telecommunication network, and the first communication network node is arranged in the telecommunication network to communicate data between the RAN and a core network node in the telecommunication network. By acquiring knowledge of variations of transport characteristics in backhaul networks, RAN capabilities may be adjusted, e.g. by performing handover of UEs to other radio base stations which have better backhaul transport characteristics. Thereby, user experience for the users of the UE may be increased. In addition, an operator of the communication network may make better use of installed transport capacity.
