Embodiment Construction

[0027] Various aspects are now described with reference to the figures. In the following description, for purposes of explanation, numerous specific details are set forth in order to provide a thorough understanding of one or more aspects. It may be evident, however, that such aspects may be practiced without these specific details. Also, the term “component” as used herein may be one of parts constituting a system, may be hardware, firmware, and / or software stored on a computer-readable medium, and may be divided into other components.

[0028] In general, the present disclosure relates to apparatus and methods for sending feedback for a mix of on-scheduled and on-demand acknowledgments (ACKs or Acks) in response to received transmissions in a wireless communication system. It should be understood that acknowledgments discussed herein may generally refer to some type of response to a transmission, and may include positive acknowledgments (sometimes referred to as Acks), nega...

Abstract

Described are methods, apparatuses, and computer-readable mediums of enabling transmission of feedback for a mixture of pre-timed and on-demand acknowledgements. In an example, an apparatus receives afirst transmission and a second transmission. The apparatus determines that the first transmission is associated with pre-timed acknowledgement rules and also determines that the second transmissionis associated with on-demand acknowledgement rules. The apparatus transmits a first acknowledgement of the first transmission according to the pre-timed acknowledgement rules and transmits a second acknowledgement of the second transmission according to the on-demand acknowledgement rules.
