| 发明名称 | Apparatuses and methods for managing pending HARQ retransmissions | ||
| 摘要 | Methods and systems present solutions to, for example, the problem of unnecessary preparedness for suspended retransmissions in the user equipment (UE) which contributes to power drain in the device battery. One method for monitoring a Physical Downlink Control Channel (PDCCH) for adaptive retransmission grants in a radio communication system includes: monitoring, by a user equipment (UE), the PDCCH for adaptive retransmission grants; receiving, by the UE, a hybrid automatic repeat request (HARQ) acknowledge (ACK) message, and ceasing, by the UE, to monitor the PDCCH for adaptive retransmission grants after receipt of the HARQ ACK message. | ||

| 主权项 | 1. A method for monitoring a Physical Downlink Control Channel (PDCCH) for adaptive retransmission grants in a radio communication system, the method comprising: monitoring by a user equipment (UE), the PDCCH for adaptive retransmission grants; receiving by the UE, a hybrid automatic repeat request (HARQ) acknowledge (ACK) message; receiving, by the UE, a Medium Access Control (MAC) control element (CE); and entering, by the UE, a reduced power sleep mode after receiving the HARQ ACK message based on the received MAC CE. | ||
