摘要： A method of allocating orthogonal resources, a computer program for so doing, a network node and network control node are disclosed. One method comprises determining user equipment within a radio cell of the network node that are considered to be edge user equipment located towards an edge of the radio cell and user equipment that are considered to be centre user equipment located towards a centre of the radio cell. Allocating a subset of the set of resources to the edge user equipment and allocating resources from the set of resources that are not allocated to the edge user equipment to the centre user equipment; and indicating to at least some adjacent network nodes that the subset of the resources is not available to the adjacent network node for allocation to edge user equipment.

摘要： A multiple input multiple output network node, an access network node, a computer program and method are disclosed. The method comprises prior to transmitting signals in an unlicensed band: estimating at least one channel within the unlicensed band between at least one access network node operable to transmit in the unlicensed band and the multiple input multiple output network node; determining precoding operations required to generate a null signal beam for the at least one estimated channel; monitoring the unlicensed band using the determined precoding operations. In response to detecting the unlicensed band to be clear of signals: transmitting at least one signal in the unlicensed band with the null beam in place such that no signal is transmitted on the at least one estimated channel.

摘要： Aspects and embodiments provide a method of allocating frame resource elements in a wireless communication network for the purpose of channel estimation, and a base station and computer program product operable to perform that method. One aspect provides a method of allocating resource elements in a wireless communication network. The method comprises: determining a channel estimate associated with each user equipment to be scheduled in a given frame; assessing whether a validity time associated with each channel estimation value, e.g. CSI, associated to each user equipment is still valid or should be considered as expired; and allocating the frame resource elements to either channel estimation, when the current channel estimation is not anymore valid, or else to data transmission, when it is still valid. The validity time comprises a number of frames and is selected according to an associated mobility of the user equipment, wherein for semi-static UEs the current channel estimation is considered to be valid for a longer time. Aspects and embodiments provide a method for an adaptive and user-centric frame design in massive MIMO that takes into account mobility of UEs and thus may mitigate waste of resource associated with use for unnecessary channel estimation purposes.
