US 2022/0046493 A1 · CONTROL CHANNEL WITH FLEXIBLE NUMEROLOGY

Abstract

Techniques are described for wireless communication. One method for wireless communication includes transmitting, to a user equipment (UE), an indication of a control channel subcarrier spacing to be used by the UE; and transmitting a control message having a subcarrier spacing in accordance with the indication. Another method for wireless communication includes transmitting, to a UE, an indicator channel identifying at least a subcarrier spacing to be used in one or more subsequent control channels. One or more subsequent control channels are then transmitted in accordance with the subcarrier spacing indicated by the indicator channel.

Claims6

Dependent claims

A method for wireless communication, comprising:

transmitting, to a user equipment, a master information block (MIB) including a first indication of a first control channel subcarrier spacing;
transmitting, to the user equipment, a control message having the first control channel subcarrier spacing in accordance with the first indication of the first control channel subcarrier spacing;
transmitting, to the user equipment, a system information block (SIB) including a second indication of a change to a second control channel subcarrier spacing, which is different from the first control channel subcarrier spacing;
and
transmitting, to the user equipment, a control message having the different second control channel subcarrier spacing in accordance with the second indication of the change to the second control channel subcarrier spacing.
