Bandwidth part switching techniques in wireless communications

A method for wireless communication at a network entity, comprising:

• transmitting, to a user equipment (UE), wideband communications over a first bandwidth part of a total bandwidth available for communications between the network entity and the UE;
• transmitting an end of burst indicator to the UE that identifies a last slot of the wideband communications, wherein the end of burst indicator is provided prior to transmission of the last slot of the wideband communications;
• and
• switching, based at least in part on the end of burst indicator, UE communications from the first bandwidth part to a second bandwidth part subsequent to the last slot of the wideband communications, wherein the second bandwidth part spans a narrower portion of the total bandwidth than the first bandwidth part.

A user equipment (UE) for wireless communication, comprising:

• one or more memories storing processor-executable code;
• and
• one or more processors coupled with the one or more memories and individually or collectively operable to execute the code to cause the UE to:
• receive, from a network entity, wideband communications over a first bandwidth part of a total bandwidth available for communications between the network entity and the UE;
• identify a last slot of the wideband communications based at least in part on an end of burst indicator provided with control information from the network entity, wherein the last slot of the wideband communications is identified prior to reception of the last slot of the wideband communications;
• and
• switch, based at least in part on the identifying, from the first bandwidth part to a second bandwidth part subsequent to the last slot of the wideband communications, wherein the second bandwidth part spans a narrower portion of the total bandwidth than the first bandwidth part.

A network entity for wireless communication, comprising:

• one or more memories storing processor-executable code;
• and
• one or more processors coupled with the one or more memories and individually or collectively operable to execute the code to cause the network entity base station to:
• transmit, to a user equipment (UE), wideband communications over a first bandwidth part of a total bandwidth available for communications between the network entity and the UE;
• transmit an end of burst indicator to the UE that identifies a last slot of the wideband communications, wherein the end of burst indicator is provided prior to transmission of the last slot of the wideband communications;
• and
• switch, based at least in part on the end of burst indicator, UE communications from the first bandwidth part to a second bandwidth part subsequent to the last slot of the wideband communications, wherein the second bandwidth part spans a narrower portion of the total bandwidth than the first bandwidth part.
