摘要： The present disclosure relates to a method of a radio base station (20) of controlling allocation of resources to wireless communication devices (23, 24), and a radio base station (20) performing the method. In an aspect, a method of a radio base station (20) of controlling allocation of resources to wireless communication devices (23, 24) is provided. The method comprises providing (S101) a first location with radio coverage using at least a first frequency band and a second frequency band and a second location with radio coverage using the first frequency band, the second frequency band being located at a higher frequency than the first frequency band and temporarily reallocating (S102) resources of the second frequency band from the first location to the second location upon acquiring an indication that a wireless communication device (24) at the second location requires improved coverage.

摘要： A control node, a wireless device, an access point and methods therein, to achieve estimation of path loss and channel response in a radio link between the wireless device and the access point. The control node assigns one and the same pilot sequence to the wireless device and at least one other wireless device in communication with the access point, and further assigns different device-specific phase rotations to the wireless devices. The devices then apply their assigned phase rotations to the pilot sequence when transmitting the pilot sequence in consecutive coherence intervals to the access point which is thereby able to de-spread the received pilot sequences and estimate path loss and channel response in the radio link.

摘要： The disclosure provides methods and apparatus which relate to control channel decoding in a wireless communications network. In one aspect, there is provided a method in a wireless device for a wireless communications network. The method includes receiving a first set of coded control symbols on a physical control channel in a first time slot, receiving a second set of coded control symbols on the physical control channel in a second time slot subsequent to the first time slot, and attempting to decode a control message based on the first set of coded control symbols and the second set of coded control symbols using one or more soft-combining techniques.

摘要： Embodiments herein relate to a method performed by a wireless device (10) for handling neighbour relationships between radio network nodes in a wireless communication network. The wireless device (10) obtains a request from a first radio network node to provide an identity of a mobility reference signal (MRS) handler associated with one or more MRSs. Furthermore, the wireless device (10) obtains the identity of the MRS handler, which identity is in direct association with at least one MRS out of the one or more MRSs, and reports to the first radio network node, the identity of the MRS handler.

摘要： Method performed by a first network node (111) for handling a request for access from a wireless device (130). The wireless device (130) and the first network node (111) operate in a wireless communications network (100). The first network node (111) receives (401) a first message from the wireless device (130) comprising a request for access. The first network node (111) determines (402) a delay for sending a second message to the wireless device (130) in response to the received first message. The first network node (111) then sends (403) the second message to the wireless device (130) using said determined delay, the second message comprising a response to the request for access.

摘要： There is provided mechanisms for synchronization in a wireless communications network. A method is performed by a transmitting device. The method comprises transmitting a first synchronization signal on a first time/frequency resource in a time/frequency grid. The method comprises receiving a response to the first synchronization signal from a receiving device. The method comprises transmitting a second synchronization signal on a second time/frequency resource in the time/frequency grid to the receiving device, wherein the second time/frequency resource spans a larger portion of the time/frequency grid than the first time/frequency resource.

摘要： Disclosed is a method and a network node for handling random access in a wireless communication network. The method includes receiving a random access preamble when a first number of receivers are active and a second number of the receivers are inactive, and sending a random access response to the received random access preamble. The method further includes determining whether a reception requirement for a subsequent random access procedure message is fulfilled, the subsequent random access procedure message being sent subsequent to the network node sending the random access response, the reception requirement being either whether the random access procedure message is received at the network node or whether the random access procedure message that is received has a sufficient quality, and when the reception requirement is determined not fulfilled, activating at least some of the inactive second number of receivers.
