VARIABLE LENGTH TRANSMISSION TIME INTERVALS (TTI)

摘要

Methods, systems, and apparatuses for enabling and utilizing variable length transmission time intervals (TTI) are described. Latency for communications between base stations and user equipment (UEs) may be reduced by flexibly and dynamically adapting to data traffic needs. TTI for a given UE may be dynamically adjusted according to UE or system requirements and the configuration of uplink and downlink TTI. A base station may utilize dynamic grants to schedule resources within a system. A UE may receive a grant in a first portion of a variable TTI. The UE may determine a duration of the variable TTI based on the grant, and the UE may communicate accordingly. The UE may receive a subsequent grant in the variable TTI—either in the first portion or another portion—and may respond or alter its operation accordingly.

主权项

1. A method of wireless communication at a user equipment (UE), comprising:
receiving a first grant in a first portion of a variable transmission time interval (TTI), wherein the first portion of the variable TTI comprises a control region and a data region, the data region scheduled by the control region; and determining a duration of the variable TTI based at least in part on the received first grant.
