Channel quality signaling for persistent/semi-persistent radio resource allocations

An apparatus comprising:

• a memory embodying a computer program;
• and
• at least one processor;
• wherein the memory with the computer program is configured with the at least one processor to cause the apparatus at least to:
• receive a persistent or a semi-persistent uplink resource allocation that also comprises an indication to send channel quality reports;
• determine a format for a channel quality report;
• and
• send, in at least first transmissions of user data for instances of the persistently or semi-persistently allocated uplink resource, user data and a channel quality report according to the determined format,
• wherein the indication to send channel quality reports comprises a single bit.

• send, in at least first transmissions of user data for instances of the persistently or semi-persistently allocated uplink resource, user data and a channel quality report according to the determined format,
• wherein the format for the channel quality report is determined by mapping from a transmission mode to one of several channel quality report formats, wherein a user equipment is configured to receive a downlink shared channel according to the transmission mode used for the mapping.
