US 10,594,468 B2 · Efficient bandwidth adaptation for a wideband carrier

Abstract

Apparatus and methods are provided for efficient bandwidth adaptation for wideband carrier. In one novel aspect, the UE starts a BWP timer upon detecting one or more BWP timer starting triggering events, resets the BWP timer upon detecting BWP resetting triggering events, and switches to the default BWP upon expiration of the BWP timer. The BWP timer starting triggering events comprises decoding a command to switch away from the default BWP, the detection of end of DL data transmission in DRX mode. In another novel aspect, the UE only decodes the DCI indication for active BWP switching in the first three OFDM symbols of a subframe or a slot. In yet another novel aspect, when the SPS is configured for the serving cell for a UE with multiple BWPs, the SPS is configured for all the BWPs accordingly.

Dependent claims

A method comprising:

configuring a plurality of bandwidth parts (BWPs) by a user equipment (UE) in a wireless network, wherein a BWP includes a plurality of contiguous physical resource blocks (PRBs), and wherein the UE sets an initial BWP or one of the configured BWPs as a default BWP based on a higher-layer configuration;
starting a BWP timer upon detecting one or more BWP timer starting triggering events;
resetting the BWP timer upon detecting one or more BWP timer resetting triggering events;
and
switching to the default BWP upon expiration of the BWP timer.
