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.

主权项

1. A computer-program product comprising a non-transitory computer-readable storage medium bearing computer program code embodied therein for use with a computer, the computer program code comprising:
code for receiving at a receiver a persistent or a semi-persistent uplink resource allocation that also comprises an indication to send channel quality reports; code for determining by a processor a format for a channel quality report; and code for sending from a transmitter user data and a channel quality report according to the determined format in at least first transmissions of user data for instances of the persistently or semi-persistently allocated uplink resource.
