Abstract:
A method for supporting multiple-input-multiple-output communications, user equipment and a computer program product are disclosed. The method comprises the steps of: determining whether an amount of data available for transmission that is greater than a maximum capacity of one the plurality of streams is below an associated threshold amount of at least another of the plurality of streams; and if so, preventing transmission of at least one of the plurality of streams. This helps to ensure that a stream is only used for transmission when the residual data is sufficient to warrant its use. This prevents, for example, inefficient use of a stream which may otherwise result in excessive transmission power, high usage of code resource and additional inter-stream interference.

Abstract:
A method for determining resources to be decoded by the UE to retrieve physical downlink control channels. A method is in a UE or an eNB and comprises the following steps of: i. determining a start position of a unit of resources in one physical resource block pair; ii, determining a gap between two of the units; and iii. determining a set of units, in a given plurality of physical resource block pairs, according to said start position and said gap, as the resources to be decoded. In this way, the eNB and the UE can locate all the resources for the EPDCCH, namely the search space is determined. This aspect allows a balance between the number of blind decoding and eNB scheduling flexibility in the EPDCCH search space.

Abstract:
A user equipment method, user equipment and a computer program product are disclosed. The user equipment method comprises: determining a first indicator indicative of a potential throughput for a channel between the user equipment and a base station when using a network assist interference suppression scheme; determining a second indicator indicative of a potential throughput for the channel between the user equipment and the base station without using the network assist interference suppression scheme; calculating an effective indicator indicative of an effective potential throughput for the channel between the user equipment and the base station based on the first indicator and the second indicator; and transmitting the effective indicator to the base station. In this way, rather than transmitting only an indicator of the potential throughput when not using the network assist interference suppression scheme or only transmitting an indicator which indicates the throughput when using the network assist interference suppression scheme, instead an effective throughput is transmitted which may be based on both of these indicators and so is likely to be more stable. Also, by only transmitting a single throughput indicator, the need for additional signalling to carry those additional indicators is avoided, which enables an improved indicator to be provided using existing signalling.
