US 11,778,598 B2 · Framing, scheduling, and synchronization in wireless systems

Abstract

A WTRU may receive downlink control information (DCI) indicating a start of a frame. The DCI may be received on a control channel, such as the Physical Downlink Control Channel (PDCCH) from an eNB, base station, AP, or other infrastructure equipment operating in a wireless communications system. The WTRU may decode the DCI and may determine a transmit time interval (TTI) duration, which may be expressed in terms of an integer number of basic time intervals (BTIs). The WTRU may determine a downlink (DL) transmission portion and assignment and an uplink (UL) transmission portion and UL grant based on the received DCI. Additionally, the WTRU may determine the start of the UL portion based on an offset (toffset). The WTRU may receive data in a DL portion of the frame and may transmit in an UL portion of the frame based on the determined UL grant and TTI duration.

Claims8

Dependent claims

A method for use in a wireless transmit/receive unit (WTRU), the method comprising:

receiving, from a first network node using a first radio access technology (RAT), an indication of periodic transmissions of a signal including synchronization signals from a second network node using a second RAT, wherein the indication of periodic transmissions corresponds to a system time of the first network node;
determining, from the received signal including the synchronization signals, an indication of a frame timing associated with the second network node;
and
receiving, from the second network node, the signal including the synchronization signals based on the indication of the periodic transmissions.
