US 10,757,728 B2 · Multiple transmission time interval coexistence

Abstract

Methods, systems, and devices for wireless communication are described. Different transmission time interval (TTI) durations may be supported and configured to coexist with one another. A set of TTIs with a relatively short duration may overlap in time with longer duration TTIs. Boundaries of TTIs with a relatively short duration may be configured to align with boundaries of relatively longer duration TTIs. For example, TTIs that are a Long Term Evolution (LTE) subframe, an LTE slot, and a duration of two LTE symbol periods may be supported. Two-symbol period TTIs may align with or be embedded within slot-duration TTIs, which, in turn, may align with or be embedded within a subframe. In some examples, one or more symbol periods of a subframe may be designated as a gap between two-symbol TTIs within the subframe, or such symbols may be merged with a two-symbol TTI within the subframe.

Dependent claims

A method for wireless communication, comprising:

identifying a duration of a control region of a transmission time interval (TTI) of a first duration;
determining a first pattern for a set of TTIs of a second duration within the TTI of the first duration based at least in part on the duration of the control region, wherein symbol periods of the control region are non-overlapping with symbol periods of the set of TTIs of the second duration;
and
communicating via at least one of the set of TTIs of the second duration based at least in part on the first pattern for the set of TTIs of the second duration.

1 more element

An apparatus for wireless communication, in a system comprising:

a processor;
memory in electronic communication with the processor;
and
instructions stored in the memory and operable, when executed by the processor, to cause the apparatus to:
identify a duration of a control region of a transmission time interval (TTI) of a first duration;
determine a first pattern for a set of TTIs of a second duration within the TTI of the first duration based at least in part on the duration of the control region, wherein symbol periods of the control region are non-overlapping with symbol periods of the set of TTIs of the second duration;
