摘要： The invention discloses methods and arrangements for use of random access resources in a wireless communication system. At a service request from the UE, the base station will assign a random access resource (a SYNC_UL code) to the UE. The UE will send a signal using the assigned resource, upon which the base station will measure signal strength, time of arrival or location of the user equipment. The invention thus solves the problem of inefficient use of spreading factor codes as resources for sending signals intended for measuring.

摘要： A method (600) for a cellular system (100) with a controlling node (130) for a cell and a node (140) for radio network control. More than one uplink carrier frequency (605) is used in a cell (110) and the cell has an uplink channel with two types of transmission resources (610), scheduled and non-scheduled. The controlling node (130) of a cell is given control (615) over the scheduled transmission resources of the users (120), and the node (140) for radio network control is given initial control (620) over the non-scheduled transmission resources of the users. The controlling node (130) alone or together with a user (120) is subsequently (630) given control of the user's (120) non-scheduled transmission resources, to ensure that the user's non- scheduled uplink transmissions use the same uplink carrier frequency as the user's scheduled transmissions.

摘要： The invention discloses a method and a base station for phase compensation in beamforming in a multi-antenna Time Division Duplex (TDD) communication network. In a first transmission mode, e.g. TM4 or TM8, the base station estimates a first phase shift between a first antenna port and a reference antenna port in uplink based on a measurement of a first Sounding Reference Signal (SRS). Then the base station estimates in the first transmission mode a second phase shift between the first antenna port and the reference antenna port in downlink based on a Channel State Information (CSI) feedback from a User Equipment (UE), and calculates a parameter indicative of a difference between the first phase shift and the second phase shift. In a second transmission mode, e.g. TM7 or TM8, the base station estimates a third phase shift between the first antenna port and the reference antenna port in uplink based on a measurement of a second SRS, and calculates in the second transmission mode, a fourth phase shift between the first antenna port and the reference antenna port in downlink as a difference between the third phase shift and the parameter. The base station then compensates in the second transmission mode, the phase of input signal on the first antenna port by the fourth phase shift for beamforming.

摘要： In a transmission scheme for transmitting data over a connection connecting a transmitting Main Unit and a receiving Radio Unit of a cellular radio system, where the transmitted data corresponds to user-plane data in the form of digital baseband data for different antenna- carriers, the digital signal is transmitted over the connection, e.g. a fiber, before spreading and combining is provided. The power and weight factor is transmitted separately with a few additional bits. Hereby, the Digital signal before spreading and combining is transmitted in the fiber instead of the combined multi-code signal.
