Abstract
Wireless communications systems and methods related to channel occupancy time (COT) sharing in multi-subscriber identity module (MultiSim) devices are provided. A user equipment (UE) transmits, based on a first subscriber identity during a first portion of a channel occupancy time (COT) in an unlicensed band, a first communication signal. The UE transmits, based on a second subscriber identity during a second portion of the COT, a second communication signal, the second subscriber identity being different from the first subscriber identity.
Claims25
A method of wireless communication performed by a user equipment (UE), the method comprising:
- performing a listen-before-talk (LBT) procedure to initiate a channel occupancy time in an unlicensed band, the COT being associated with a first subscriber identity;
- transmitting, based on the first subscriber identity during a first time duration of the COT, a first communication signal;
- communicating, by a first subscriber identity module (SIM) disposed in the UE, information with a second SIM disposed in the UE, the information being for sharing a second time duration of the COT;
- and
- transmitting, by the UE based on the information for sharing the second time duration of the COT and based on a second subscriber identity during the second time duration of the COT, a second communication signal, the second subscriber identity being different from the first subscriber identity.
A user equipment (UE) comprising:
- a transceiver;
- and
- a processor in communication with the transceiver, wherein the UE is configured to:
- perform a listen-before-talk (LBT) procedure to initiate a channel occupancy time in an unlicensed band, the COT being associated with a first subscriber identity;
- transmit, based on the first subscriber identity during a first time duration of the COT, a first communication signal;
- communicate, by a first subscriber identity module (SIM) disposed in the UE, information with a second SIM disposed in the UE, the information being for sharing a second time duration of the COT;
- and
- transmit, based on the information for sharing the second time duration of the COT and based on a second subscriber identity during the second time duration of the COT, a second communication signal, the second subscriber identity being different from the first subscriber identity.
A non-transitory computer-readable medium having program code recorded thereon for wireless communication by a user equipment (UE), the program code comprising:
- code for causing the UE to perform a listen-before-talk (LBT) procedure to initiate a channel occupancy time in an unlicensed band, the COT being associated with a first subscriber identity;
- code for causing the UE to transmit, based on the first subscriber identity during a first time duration of the COT, a first communication signal;
- code for causing the UE to communicate, by a first subscriber identity module (SIM) disposed in the UE, information with a second SIM disposed in the UE, the information being for sharing a second time duration of the COT;
- and
- code for causing the UE to transmit, based on the information for sharing the second time duration of the COT and based on a second subscriber identity during the second time duration of the COT, a second communication signal, the second subscriber identity being different from the first subscriber identity.
A user equipment (UE) comprising:
- means for performing a listen-before-talk (LBT) procedure to initiate a channel occupancy time in an unlicensed band, the COT being associated with a first subscriber identity;
- means for transmitting, based on the first subscriber identity during a first time duration of the COT, a first communication signal;
- means for communicating, by a first subscriber identity module (SIM) disposed in the UE, information with a second SIM disposed in the UE, the information being for sharing a second time duration of the COT;
- and
- means for transmitting, by the UE based on the information for sharing the second time duration of the COT and based on a second subscriber identity during the second time duration of the COT, a second communication signal, the second subscriber identity being different from the first subscriber identity.
