Problems solved by technology

[0007] Unfortunately, continued decoding of the acknowledgment channel may limit the amount of time the UE stays in a low power state, which may result in unnecessary power consumption

Embodiment Construction

[0020] As noted above, in some scenarios, the UE may be expected to continue decoding the acknowledgment channel even after the UE has received an acknowledgment (ACK) that the base station successfully received the UL transmission. This continued decoding may be desirable for a number of reasons. For example, in the event that a positive ACK is actually received in error (eg, due to a NACK-to-ACK transition during transmission), this continued decoding may allow the UE to detect subsequent NACKs, thereby allowing the UE to retransmit and avoid UL packet loss. As another example, continuing to decode may allow ACKs to be used to suspend retransmissions even if the base station did not successfully receive the UL transmission.

[0021] Unfortunately, this continued decoding of the acknowledgment channel can greatly limit the amount of time the UE can stay in the low power state. In other words, the UE has to exit the low power state prematurely in order to decode the acknowled...

Abstract

Certain aspects of the present application may help reduce power consumption by allowing a UE to remain in a low power state by not attempting to decode an ACK / NACK transmission after receiving an acknowledgment (ACK).

Description

[0001] Claiming Priority Based on 35 U.S.C. §119 [0002] This patent application claims the benefit of U.S. Provisional Patent Application Serial No. 61 / 534,809, filed September 14, 2011, which is assigned to the assignee of the present application and is hereby incorporated by reference expressly incorporated herein. technical field [0003] Certain embodiments of the present application relate generally to wireless communications, and more particularly, to methods and apparatus for reducing power consumption. Background technique [0004] Wireless communication networks are widely deployed to provide various communication services such as voice, video, packet data, messaging, broadcast, and so on. These wireless networks may be multiple-access networks that support multiple users by sharing available network resources. Examples of these multiple access networks include Code Division Multiple Access (CDMA) networks, Time Division Multiple Access (TDMA) networks, Frequenc...
