METHOD, APPARATUS AND COMPUTER PROGRAM PRODUCT FOR DETERMINING UPLINK RESOURCES FOR TRANSMITTING HARQACK IN TDD UL-DL RECONFIGURATION

摘要

Methods, apparatuses and computer program products for determining uplink resources to transmit hybrid acknowledgment repeat request (HARQ) from a first uplink-downlink (UL-DL) configuration to a second UL-DL configuration in TDD UL-DL reconfiguration are provided. A first uplink resource for transmitting HARQ information associated with the first UL-DL configuration is determined, and a second uplink resource for transmitting HARQ information associated with the second UL-DL configuration is determined based on the first uplink resource. The information related to the second uplink resource for use by the reconfigured UE(s) is transmitted to the reconfigured UE(s). The reconfigured UE(s) receive a reconfiguration message and information on the second uplink resource, and transmit HARQ information using the second resource for the reconfigured frames.
