Abstract

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.

Claims16

Dependent claims

A method performed by a radio network node, the method comprising:

determining a time division duplex, TDD, configuration, wherein the TDD configuration comprises one or more subframes preconfigured as downlink subframes, one or more subframes preconfigured as uplink subframes, and one or more flexible subframes each preconfigured to be dynamically allocated either as an uplink subframe or as a downlink subframe;
determining, for each flexible subframe, an allocation priority and/or allocation probability of using the flexible subframe as an uplink subframe or as a downlink subframe, wherein determining the allocation priority and/or allocation probability comprises:
determining the allocation priority and/or allocation probability of using each resource block in the flexible subframe for uplink or downlink transmission;
and
assigning the allocation priority and/or allocation probability for scheduling one or more resource blocks in each flexible subframe;
and
allocating resources to at least one user equipment, UE, based on the determined allocation priority and/or allocation probability, wherein allocating the resources to the at least a one UE comprises:
assigning resources to the at least one UE in the flexible subframe based on the determined allocation priority and/or allocation probability;
and
signalling to the UE the determined allocation priority and/or allocation probability.

7 more elements

A radio network node, comprising:

a communication interface configured for wireless communication;
a processor;
and
a memory storing computer program code which, when run in the processor causes the radio network node to:
determine a time division duplex, TDD, configuration, wherein the TDD configuration comprises one or more subframes preconfigured as downlink subframes, one or more subframes preconfigured as uplink subframes, and one or more flexible subframes each preconfigured to be dynamically allocated either as an uplink subframe or as a downlink subframe;
determine, for each flexible subframe, an allocation priority and/or allocation probability of using the flexible subframe as an uplink subframe or as a downlink subframe, wherein determining the allocation priority and/or allocation probability comprises:
determining the allocation priority and/or allocation probability of using each resource block in the flexible subframe for uplink or downlink transmission;
and
assigning the allocation priority and/or allocation probability for scheduling one or more resource blocks in each flexible subframe;
and
allocate resources to at least one user equipment, UE, based on the determined allocation priority and/or allocation probability, wherein allocating the resources to the at least a one UE comprises:
assigning resources to the at least one UE in the flexible subframe based on the determined allocation priority and/or allocation probability;
and
signalling to the UE the determined allocation priority and/or allocation probability.
