Abstract: Channel multi-input multi-output (MIMI) systems can be configured with a variable number of codewords where the network an change the number of codewords based on channel conditions, user equipment capability, etc. Thus, the network can efficiently utilize feedback channel overhead while simultaneously improving the capacity of the system. Instead of configuring the UE with a fixed number of codewords for all the channel conditions, the network can change the number of codewords dynamically or semi-statically. The network can determine the number of codewords based on measurements and recommendations from the UE. Alternatively, the network can determine the number of codewords on its own.

Abstract: A method for assigning downlink transmit power levels to radio nodes (RNs) in a small cell radio access network (RAN) includes assigning initial power levels to the RNs. For each cell, first events are counted indicating that UEs receiving a signal from their serving cells with a signal strength below a specified value have entered a coverage hole. For each cell, second events are counted indicating that UEs have re-established a previous connection on one of the cells. For each pair of cells, a coverage hole is identified between them if the number of first events for one cell exceeds a threshold and a number of second events or re-establishment of a previous connection on the other cell exceeds another threshold. For each identified coverage hole, the downlink transmit power level is increased of at least one RN in the pair of cells between which the coverage hole is identified.
