摘要： There is provided mechanisms for determining frequency location of a primary cell (PCell) for a wireless device in a carrier aggregation supported communications network having access to a group of low frequency bands and a group of high frequency bands. A method is performed by a network node. The method comprises acquiring an uplink load level for the group of low frequency bands. The method comprises acquiring a pathloss level between a wireless device served by the communications network and the network node. The method comprises selecting, from the acquired uplink load level and pathloss level, which one of the group of low frequency bands and the group of high frequency bands to place the frequency location of the PCell for the wireless device.

摘要： A method and transition device for enabling communication of data between a remote radio unit and a central baseband unit in a wireless network. When detecting a first interface configuration used by the remote radio unit and a second interface configuration used by the baseband unit, the transition device configures interface functions, based on the first and second interface configurations. The interface functions are selected from a set of predefined interface functions associated with different interface configurations. The transition device then establishes a data flow between the remote radio unit and the central baseband unit over the transition device, and performs conversion between the first interface configuration and the second interface configuration for data communicated in the data flow, using the selected interface functions.

摘要： A method for operating a radio access system comprises configuring a first carrier and a second carrier for use for radio access in a first radio access system. The second carrier is configured for frequency division duplex signalling. A useful frequency band of the second carrier is defined to, at least partially, overlap in frequency with a useful frequency band of a third carrier of a second radio access system. At least a part of the useful frequency band of the second carrier overlaps in frequency with guard bands of the third carrier. A method for signal scheduling comprises scheduling, in a first radio access system having a first carrier with a first carrier frequency band and a second carrier with a second carrier frequency band, uplink signals in the second carrier. Network nodes for carrying out the methods are also presented.

摘要： A method for configuring transmission order of uplink data, the method performed by a radio equipment (“RE”) of an access node. The RE has a RE controller (“REC”)-RE interface that communicatively couples the RE with a REC of the access node. The method includes receiving instructions from the REC that indicate a scheduling prioritization for transmission by the RE of uplink data between the RE and the REC over the REC-RE interface. The uplink data can be received by the RE on the radio interface. The method can further include transmitting the uplink data on the REC-RE interface according to the instructions, resulting in the scheduling prioritization of the uplink data.
