Abstract: In an aspect of the disclosure, a method, a computer-readable medium, and an apparatus are provided. The apparatus may be a user equipment (UE) or component thereof. The apparatus may be configured to transmit to a base station a first request to transmit data in a buffer. The apparatus may be further configured to transmit to the base station a second request to transmit the data in the buffer in absence of a grant in response to the first transmit request. The apparatus may be further configured to remain awake for at least a portion of a scheduled discontinuous reception (DRX) sleep state following the transmission of the second request.

Abstract: A method for downlink frequency selective scheduling in LTE MAC based on channel quality feedback is disclosed. Existing methods for resource allocation have no means for efficient utilization of the resources and allocation of the available downlink bandwidth to the UE with low computation overhead. These methods do not ensure that the UEs that possess channel quality feedbacks are allocated their best sub-bands for transmission in time and compute efficient manner. The proposed method employs CQI based feedback from the UEs for allocation of the downlink bandwidth. The method defines a threshold value for the CQI and UEs that have sub-bands with CQI lesser than the defined threshold value will not be allocated resources in the corresponding sub-band.
