摘要： The present disclosure introduces allocation of resources to one or more UEs based on a determined allocation priority and/or allocation probability in, e.g., Time Division Duplex (TDD) based radio communication networks. The disclosed technology provides the ability for a subframe to be configured as a "flexible" subframe, which can be dynamically allocated as either a downlink subframe or an uplink subframe. For each "flexible" subframe, an allocation priority and/or allocation probability is determined and subsequent resource allocation to user equipments (UEs) can be based on the determined allocation priority and/or allocation probability. Hereby, it is made possible to reduce interference in, e.g., TDD based radio communication networks.

The base station then indicates the selected up link transmit diversity mode to the mobile terminal, which changes to the up link transmit diversity mode indicated by the base station. The methods and arrangements enable a faster and more flexible UE up link transmit diversity mode adaptation.
