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.
Claims1
A method comprising:
- establishing, by a user device, connections associated with a first carrier and a second carrier;
- receiving, by the user device and via the first carrier, an uplink grant in subframe n;
- 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, wherein the first subframe corresponds to subframe n+4;
- based on the first subframe overlapping in time with a time period for wireless communication between user devices associated with the second carrier, not transmitting the uplink signal in the first subframe;
- and
- transmitting, based on a reception timing of the uplink grant and after not transmitting the uplink signal in the first subframe, the uplink signal in subframe n+12.
