摘要： A method by a wireless device includes transmitting at least one radio channel measurement associated with one of a plurality of transmitting and receiving point (TRPs). The wireless device receives information indicating a selection of a first subset of TRPs for use in receiving one or more signals from at least one TRP and/or transmitting one or more signals to at least one TRP. The selection of the first subset of TRPs is based at least in part on the radio channel measurement, and the first subset of the TRPs is less than all of the plurality of TRPs.

摘要： In mobile communications networks, requirements on signal distortion may be fulfilled at a lower bit rate, or alternatively quantization noise be reduced for a given bit rate, by including fractional exponent bits in a block floating point format. One or more fractional exponent bits may apply to all samples in the block. Alternatively, fractional bits may apply to sub-blocks within the block. The optimal number of fractional bits depends on the number of samples in the block.

摘要： A method and transition device (200) for enabling communication of data between a remote radio unit (202) and a central baseband unit (204) in a wireless network. When detecting a first interface configuration used by the remote radio unit (202) and a second interface configuration used by the baseband unit (204), the transition device (200) configures interface functions, based on the first and second interface configurations. The interface functions are selected from a set of predefined interface functions (400A) associated with different interface configurations. The transition device (200) then establishes a data flow between the remote radio unit (202) and the central baseband unit (204) over the transition device (200), 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 and a remote digital unit in a central office of a core network, for handling a radio communication for a mobile terminal (T1) being connected to an access point (302) at a local site (300). The remote digital unit determines that the mobile terminal can be served locally by a local digital unit (308) connected to a local signal switching unit (304) at the local site, and instructs the local digital unit to locally process signals to or from the mobile terminal in the communication. The remote digital unit further schedules the signals over a radio interface between the mobile terminal and the access point, and sends (316) updated scheduling information to the local digital unit to indicate the scheduling, thereby enabling the local digital unit to handle the radio communication according to the updated scheduling information. In this way, the functionality of a base station is divided into a relatively simple digital unit and switching function at the local site and a more advanced digital unit with scheduling function at the central office, such that the costs for implementing radio access at a local site are low and tromboning of communicated signals over the core network can be avoided.

摘要： Transceiver node and method therein for enabling dynamic bandwidth assignment in bi-directional Time Division Duplexing, TDD, multicarrier communication over wire lines. The transceiver node is operable to be coupled to a plurality of loops, where each loop is terminated by a respective network terminal, NT. The method comprises collecting traffic reports from local and remote queues associated with uplink and downlink traffic on the plurality of loops, and determining an actual demand for upstream and downstream bandwidth, respectively, for each of the plurality of loops, based on the collected traffic reports. The method further comprises deriving an Upstream/Downstream, US/DS, frame partitioning based on the determined actual demand for upstream and downstream bandwidth, and providing an indication of the derived US/DS frame partitioning to the NTs. NTs are then scheduled in accordance with the derived partitioning.

摘要： A method 1700 is performed by a baseband unit (BBU) 104 for scaling beamforming weights (BFWs) to assist a Radio Unit (RU) 102 with beamforming. The method includes obtaining 1702 a plurality of frequency-domain BFWs for beamforming of a number of downlink data streams in frequency-domain to be transmitted to at least one wireless device via a plurality of antennas. The BBU scales 1704 the plurality of frequency-domain BFWs based on at least one scaling factorand compresses 1706 the plurality of scaled frequency-domain BFWs. The BBU transmits 1708, to the RU, the scaled frequency-domain BFWs that have been compressed. The BBU also determines 1710 at least one user plane scaling factor for frequency-domain user plane IQ data, scales 1712 the frequency-domain user plane IQ data based on the user plane scaling factors, and transmits 1714 the scaled frequency-domain user plane IQ data to the RU.
