Problems solved by technology

In cases where LTE is employed over these networks, based on the scheduled grants, sending Hybrid Automatic Repeat / Request (HARQ) feedback may not comply with the current LTE standard, since the UE may be at a time when the feedback is due according to the LTE standard. Unable to acquire channel at all times (e.g. performing successful CCA)
Additionally, performing CCA for sending each feedback transmission can be taxing on network resources and can cause additional delays in delivering feedback

Embodiment Construction

[0022] The detailed description set forth below in conjunction with the accompanying drawings is intended as a description of various configurations and is not intended to represent the only configurations in which the concepts described herein may be practiced. The detailed description includes specific details to provide a thorough understanding of various concepts. It will be apparent, however, to one skilled in the art that these concepts may be practiced without these specific details. In some instances, well-known structures and components are shown in block diagram form in order to avoid obscuring such concepts.

[0023] Described herein are aspects related to communicating feedback in a listen-before-talk (LBT) wireless network (e.g., a wireless local area network (WLAN)) employing a wireless communication technique (e.g., a wireless wide area network) using scheduled resources. (WWAN) technology). For example, this may include LTE in Unlicensed Band (LTE-U) networks...

Abstract

Aspects described herein relate to communicating feedback in a wireless network. An indication may be received from the access network node to transmit feedback for the plurality of subframes to the access network node. Multiple process identifiers may be determined associated with transport blocks received in multiple subframes. Feedback for multiple process identifiers received in multiple subframes may be grouped, and the grouped feedback and / or a feedback tag indicating the multiple subframes may be sent to the access network node.

Description

[0001] priority statement [0002] This patent application claims priority to non-provisional application No. 14 / 819,191, filed August 5, 2015, entitled "COMMUNICATING FEEDBACK INLISTEN-BEFORE-TALK (LBT) WIRELESS NETWORKS," and filed August 2014 Priority to Provisional Application No. 62 / 035,324, entitled "COMMUNICATING FEEDBACK IN LISTEN-BEFORE-TALK (LBT) WIRELESS NETWORKS," filed on the 8th, assigned to the assignee of the present application, and incorporated by reference manner is expressly incorporated herein. technical field [0003] In general, the present disclosure relates to multi-radio communication systems, and more specifically, to the transmission of feedback in wireless networks. Background technique [0004] Wireless communication systems are widely deployed to provide various telecommunication services such as telephony, video, data, messaging and broadcast. A typical wireless communication system may employ multiple access techniques capable of supporting...
