Abstract

Apparatuses, systems, and methods for determining and applying switching periods, e.g., incorporating timing advance, e.g., in 5G NR systems and beyond. A UE and network may determine one or more base switching period and one or more time adjustment value related to timing advance. An adjusted switching period may be determined based on a combination of a base switching period and a time adjustment value. The network may avoid transmitting to the UE during the adjusted switching period. The UE may perform an uplink transmission switch during the base switching period.

Claims22

Dependent claims

A method, comprising:

obtaining, from a cellular network, configuration information associated with a first time adjustment value for uplink transmission switching, wherein the first time adjustment value is based on a timing advance;
receiving, from the cellular network, scheduling information to schedule:
a first uplink (UL) transmission on a first band;
and
a second UL transmission on a second band different from the first band;
determining a first adjusted switching period between the first UL transmission and the second UL transmission, the first adjusted switching period based on a base switching period adjusted by the first time adjustment value;
transmitting, to the cellular network, the first UL transmission on the first band;
receiving, from the cellular network, a first downlink (DL) transmission after transmission of the first UL transmission;
during the base switching period, switching a transmitter to the second band, wherein the base switching period begins after reception of the first DL transmission and continues during the first adjusted switching period;
and
transmitting, to the cellular network, the second UL transmission on the second band after the base switching period.

A method, comprising:

determining, configuration information for a user equipment (UE) configuration information associated with a first time adjustment value for uplink transmission switching, wherein the first time adjustment value is based on a timing advance;
transmitting, to the UE, scheduling information to schedule:
a first uplink (UL) transmission on a first band;
and
a second UL transmission on a second band different from the first band;
determining a first adjusted switching period between the first UL transmission and the second UL transmission, the first adjusted switching period based on a base switching period adjusted by the first time adjustment value related to timing advance;
receiving, from the UE, the first UL transmission on the first band;
transmitting, to the UE, a first downlink (DL) transmission after reception of the first UL transmission and prior to the first adjusted switching period;
and
receiving, from the UE, the second UL transmission on the second band after the first adjusted switching period.
