METHOD AND APPARATUS FOR MANAGING A NEW DATA INDICATOR IN A WIRELESS COMMUNICATION SYSTEM
First Claim
1. A method, comprising:
- identifying information relating to an initial transmission for a Hybrid Automatic Repeat Request (HARQ) process, the information comprising scheduling information and an initial new data indicator (NDI);
identifying information relating to a subsequent transmission for the HARQ process, the information comprising scheduling information and a subsequent NDI; and
processing the subsequent NDI as toggled from the initial NDI irrespective of a value of the subsequent NDI upon determining that the scheduling information changed between the initial transmission and the subsequent transmission for the HARQ process.

Abstract
Systems and methodologies are described herein that facilitate techniques for managing respective original transmissions and re-transmissions of information within a wireless communication system. Various mechanisms are described herein for processing a new data indicator (NDI) associated with respective transmissions conducted for one or more Hybrid Automatic Repeat Request (HARQ) processes. For example, for a HARQ process shared between distinct scheduling schemes, an NDI associated with a latter transmission can be regarded as toggled irrespective of the value of the NDI upon recognizing that a utilized scheduling scheme (e.g., as indicated via a radio network temporary identifier (RNTI) or the like) has changed between successive transmissions (e.g., from semi-persistent scheduling to dynamic scheduling), thereby allowing processing of the latter transmission as a transmission of new data. As additionally described herein, various techniques are described herein for NDI processing in the case of uplink grant and downlink assignment transmission.

39. A method, comprising:
-
identifying at least one of a cell radio network temporary identifier (C-RNTI), a semi-persistent scheduling (SPS) C-RNTI, or a temporary C-RNTI to be utilized at a given transmission time interval (TTI) in association with a Hybrid Automatic Repeat Request (HARQ) process; identifying an uplink grant for the given TTI received on a Physical Downlink Control Channel (PDCCH) for the C-RNTI or temporary C-RNTI or an uplink grant for the given TTI received in a Random Access Response; and considering a new data indicator (NDI) associated with the uplink grant to have been toggled regardless of a value of the NDI upon determining that the uplink grant is for the C-RNTI and either an uplink grant has been received for the SPS C-RNTI or a configured uplink grant has occurred since a previous received uplink grant for the C-RNTI for the HARQ process.
