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. ## Claims ### Claim 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. ### Claim 2 (depends on 1) The computer program product according to claim 1, wherein, for the case that a negative acknowledgement is received in reply to one of the sent user data with channel quality report, the computer program code further comprises: code for responding to the negative acknowledgement by re-sending in a next instance of the persistently or semi-persistently allocated uplink resource the negatively acknowledged user data with either the negatively acknowledged channel quality report or a new channel quality report. ### Claim 3 (depends on 1) The computer program product according to claim 1, wherein, for the case that a negative acknowledgement is received in reply to one of the sent user data with the channel quality report, the computer program code further comprises: code for responding to the negative acknowledgement by re-sending in a next instance of the persistently or semi-persistently allocated uplink resource the negatively acknowledged user data without any channel quality report. ### Claim 4 (depends on 1) The computer program product according to claim 1, wherein, for the case that a negative acknowledgement is received in reply to one of the sent user data with the channel quality report, the computer program code further comprises: code for responding to the negative acknowledgement by re-sending on a dynamically scheduled uplink resource the negatively acknowledged user data with either the negatively acknowledged channel quality report or a new channel quality report. ### Claim 5 (depends on 1) The computer program product according to claim 1, wherein, for the case that a negative acknowledgement is received in reply to one of the sent user data with the channel quality report, the computer program code further comprises: code for responding to the negative acknowledgement by re-sending on a dynamically scheduled uplink resource the negatively acknowledged user data without any channel quality report. ### Claim 6 (depends on 1) The computer program product according to claim 1, wherein the indication to send channel quality reports comprises a single bit. ### Claim 7 (depends on 1) The computer program product according to claim 1, 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 that is executing the method is configured to receive a downlink shared channel according to the transmission mode used for the mapping. ### Claim 8 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 sending from a transmitter to a user equipment a persistent or a semi-persistent uplink resource allocation that also comprises an indication to send channel quality reports; and code for receiving at a receiver from the user equipment user data and a channel quality report in at least first transmissions of user data for instances of the persistently or semi-persistently allocated uplink resource. ### Claim 9 (depends on 8) The computer program product according to claim 8, wherein the computer program code further comprises: code for sending from the transmitter a negative acknowledgement for one of the instances of the persistently or semi-persistently allocated uplink resource for which the user data and/or the channel quality report was not properly received; and in response to sending the negative acknowledgement, code for receiving at the receiver from the user equipment in a next instance of the persistently or semi-persistently allocated uplink resource one of: the negatively acknowledged user data with the negatively acknowledged channel quality report; or the negatively acknowledged user data with a new channel quality report; or the negatively acknowledged user data without any channel quality report. ### Claim 10 (depends on 8) The computer program product according to claim 8, wherein the computer program code further comprises: code for sending from the transmitter a negative acknowledgement for one of the instances of the persistently or semi-persistently allocated uplink resource for which the user data and/or the channel quality report was not properly received; code for sending from the transmitter to the user equipment a dynamically scheduled uplink resource allocation; and code for receiving at the receiver from the user equipment on the dynamically scheduled uplink resource one of: the negatively acknowledged user data with the negatively acknowledged channel quality report; or the negatively acknowledged user data with a new channel quality report; or the negatively acknowledged user data without any channel quality report. ### Claim 11 (depends on 8) The computer program product according to claim 8, wherein the computer program code further comprises: code for configuring the user equipment to receive a downlink shared channel according to one of a plurality of transmission modes; and code for mapping from the configured transmission mode to one of a plurality of channel quality report formats, wherein the received channel quality report is according to the mapped one channel quality report format. ### Claim 12 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. ### Claim 13 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 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.
