US (84) (54) Title: RESOURCE MANAGEMENT FOR LOW LATENCY WIRELESS COMMUNICATIONS (57) : Described techniques provide for low latency transmission time interval (TTI) transmissions that may have reduced likelihood of experiencing interference from one or more neighboring transmitters. A base station may con- figure two or more sets of resources for two or more sets of wireless transmis- sions, in which low latency transmissions may be transmitted in a set of wireless transmissions using all or a portion of one of the sets of resources. The set of resources available for the low latency transmissions may be associated with a set of power parameters that provide reduced transmission powers relative to one or more of the other sets of resources. The two or more sets of resources may include one or more sub-bands of available frequency resources, one or more subsets of time resources, or combinations thereof. In some cases, neigh- boring base stations may coordinate sets of resources that have reduced power parameters.
