Channel Quality Signaling For Persistent/Semi-Persistent Radio Resource Allocations

摘要

A persistent or a semi-persistent uplink resource allocation also comprises an indication for a user equipment UE to send channel quality reports. The format for the channel quality report is determined (based on a transmission mode for which the UE receives a downlink shared channel). In at least first transmissions of user data for instances of the persistently allocated uplink resource the UE sends user data and a channel quality report according to the determined format. For the case that a NACK is received in reply to one of those sent user data with channel quality reports, four options are detailed: re-send the NACK'd user data on a next instance of the persistently allocated UL resource with or without a channel quality report, and re-send the NACK'd user data on a dynamically allocated uplink resource with or without a channel quality report.
