Abstract: A system and a method for wireless linking in a cellular communication system are disclosed such that a mobile station is maintained in simultaneous communication with at least a first node and a second node for access to the cellular communication system. Information going to and from the first node is not identical to the information going to and from the second node. In one embodiment the second node, or secondary access point is a relay node forwarding received information to and from the first node, or primary access point. In another embodiment the second node is another mobile station performing a direct mobile-to-mobile communication (MS-to-MS). In still an embodiment a first wireless link to the first node is for control information only. In still a further embodiment a second wireless link to the second node is only for communication of information from the mobile station or only for communication of information to the mobile station.

TL;DR: In this paper, a method and apparatus that reduces the likelihood of having a high peak power in any one bit position of code multiplexed downlink control channel symbols is described.

TL;DR: In this paper, a method for signaling scheduling information in a multi-carrier wireless communications system (700), as well as corresponding methods and apparatus for processing such signaling information, are disclosed.

TL;DR: In this paper, a network node (50, 60, 70), a communication device (80, 90, 100), and methods for scheduling of uplink resources in multiple time instances and transmitting in accordance with the scheduled UL resources are discussed.

TL;DR: A 5G random-access preamble format is proposed based on a short sequence of the same length as the length of the OFDM symbols that are used for other uplink physical channels, such as user data, control signaling, and reference signals, which can be used in 5G scenarios with a high amount of phase noise and frequency errors.
