摘要： The embodiments relate to a method and a base station (110) for interference management in a cellular network (100) employing Space-Division uplink (UL) downlink (DL) Duplexing (SDD). The base station (110) assigns a plurality of Remote Radio Units (RRU) as Tx RRUs operable to dedicatedly transmit downlink signals to a plurality of UEs and Rx RRUs operable to dedicatedly receive uplink signals from the plurality of UEs at the same frequency band and same time as the transmission of the Tx RRUs. The base station then suppresses the interference caused by simultaneous transmission on the same frequency band by using a Tx spatial beamforming weighting matrix and a Rx spatial beamforming weighting matrix. In addition, the base station may perform cross-talk cancellation on the residual interference contained in the received signals by using the knowledge of the downlink traffic data.

摘要： A method and arrangement for estimating the current channel quality for a data transfer in a mobile network. In a sending system entity, a channel quality estimate (CQE) associated with a data transfer to a receiving system entity in a mobile communication network is adjusted. One or more probing packets are communicated 400 between the sending system entity and the receiving system entity, each probing packet being formatted according to a predefined combination of transmission parameters. Furthermore, is a Channel State Information (CSI) report received 404 from the receiving system entity, and the CQE is adjusted 406 based on the CSI report and which probing packets have been successfully communicated. By sending a sequence of probing packets, each formatted according to a predefined combination of transmission parameters, and not waiting for each packet to be acknowledged, a fast and accurate estimation of the current channel quality is achieved.

摘要： The invention relates to a method and arrangement (500) in a network communication node (13, 14) for adapting an amount of periodic resources. The periodic resources are semi statically configured to a user equipment (11, 12) within a cell (10) of a radio telecommunications network (1). The network communication node (13,14) is comprised in the radio telecommunications network (1) and controls an amount of radio channel resources within the cell (10) of a radio control channel. The amount of periodic resources is defined as a size of a control region, which control region is at least a part of the amount of radio channel resources. The user equipment (11,12) uses a specific control signalling type on the radio control channel. The network communication node determines a traffic load in the cell (10) and obtains a periodicity requirement indication, which indication is based on the control signalling type. The network communication node then determines the size of the control region based on the determined traffic load in the cell (10) and the obtained periodicity requirement indication and thereby adapts the amount of periodic resources for the cell (10).

摘要： According to teachings presented in this document, reported channel quality information, as used for controlling one or more aspects of wireless transmission, is compensated according to an aging function that depends on channel variability. In this manner, the "amount" or extent of age-based compensation applied to the channel quality feedback for a given user— e.g., a mobile station or other item of user equipment — varies as function of that user's channel conditions. More particularly, in an advantageous approach, the aging function applied to the channel quality estimates received from a given user depends on estimates of that user's channel variability. Channel quality estimates from (or generated for) a user whose channel conditions are changing very little, or at least are changing very slowly, may be aged less aggressively than those associated with a user whose channel conditions are changing more rapidly.
