Abstract
A method of transmitting uplink data is provided. The method includes establishing connections with a first serving cell and a second serving cell, determining, by a user equipment (UE), a time period for a device-to-device (D2D) discovery signal communication via the second serving cell, determining, by the UE and based on an uplink grant received via the first serving cell, a first subframe associated with an uplink signal to an evolved NodeB (eNB) associated with the first serving cell, and in response to determining that the first subframe overlaps in time with the time period, refraining from transmitting the uplink signal in the first subframe, and transmitting, based on a retransmission timing, the uplink signal.
Claims20
A method comprising:
- receiving, by a user device and via a first carrier, an uplink grant in subframe n;
- determining a time period for a wireless communication between user devices, wherein the wireless communication between user devices is associated with a second carrier;
- determining, by the user device and based on the uplink grant received via the first carrier, a first subframe associated with an uplink signal to a base station associated with the first carrier;
- based on determining that the first subframe overlaps in time with the time period, refraining from transmitting the uplink signal in the first subframe;
- and
- transmitting, based on a reception timing of the uplink grant and based on a non-adaptive retransmission, the uplink signal in subframe n+12,
- wherein the first subframe corresponds to subframe n+4.
A method of transmitting uplink data, the method comprising:
- determining, by a user device, a time period for monitoring a wireless communication between user devices;
- determining, by the user device, a first subframe associated with a Hybrid Automatic Repeat Request (HARQ) feedback reception;
- and
- based on whether the first subframe overlaps in time with the time period, setting a state variable associated with the HARQ feedback reception to acknowledgement.
A user device comprising:
- a wireless transceiver comprising an antenna and configured to receive, via a first carrier, an uplink grant in subframe n;
- and
- one or more processors;
- configured to:
- determine a time period for a wireless communication between user devices, wherein the wireless communication between user devices is associated with a second carrier;
- determine, based on the uplink grant received via the first carrier, a first subframe associated with an uplink signal to a base station associated with the first carrier;
- based on determining that the first subframe overlaps in time with the time period, refrain from transmitting the uplink signal in the first subframe;
- and control the wireless transceiver to transmit, based on a reception timing of the uplink grant and based on a non-adaptive retransmission, the uplink signal in subframe n+12,
- wherein the first subframe corresponds to subframe n+4, and
- wherein the wireless transceiver transmits the uplink signal in the subframe n+12.
A user device of transmitting uplink data, the user device comprising:
- one or more processors;
- and
- memory storing instructions that, when executed, cause the user device to:
- determine a time period for monitoring a wireless communication between user devices;
- determine a first subframe associated with a Hybrid Automatic Repeat Request (HARQ) feedback reception;
- and
- based on whether the first subframe overlaps in time with the time period, set a state variable associated with the HARQ feedback reception to acknowledgement.
A method comprising:
- receiving, by a wireless user device from a base station, an uplink grant in a first subframe corresponding to subframe n;
- determining, based on the uplink grant, a second subframe associated with an uplink signal, wherein the uplink signal comprises an uplink shared channel transmission to the base station, and wherein the second subframe corresponds to subframe n+4;
- determining that the second subframe overlaps in time with a time period in which a wireless communication between wireless user devices is scheduled;
- based on determining that the second subframe overlaps in time with the time period, refraining from transmitting the uplink signal in the second subframe;
- and
- transmitting, based on a reception timing of the uplink grant and after the refraining from transmitting the uplink signal in the second subframe, the uplink signal in a third subframe corresponding to subframe n+12.
