Problems solved by technology

[0048] The second question is how to optimize the performance of control signaling not associated with data
[0049] The third issue concerns the different performance requirements for UL data and control signals
[0054] PAR issue: It has been shown in [R1-072224] that PAR and CM increase when higher power is configured for control rather than data
[0062] Therefore, it is difficult to provide sufficient quality for the control signal if the symbol space of the control not associated with the data is only associated with the modulation and coding scheme (MCS) used by the UL data

Embodiment Construction

[0086] figure 1 is a flow chart illustrating a procedure that may be implemented in a user equipment according to the present invention. This process can be implemented by any kind of signal processing. After entering in step 100, step 104 is performed to dynamically select the symbol space to be used for uplink signaling, such as uplink feedback control signaling not associated with data. Then, in step 106, the process 100 causes the user equipment to send uplink feedback control signaling using the selected symbol space. Then in step 108 the process returns.

[0087] figure 2 A flowchart of a process 200 that may be implemented in a base station according to the present invention is shown. After entering in step 202, step 204 is performed to dynamically select the symbol space to be used for uplink signaling, such as uplink feedback control signaling not associated with data. Then, in step 210, the process 200 enables the base station to send uplink feedback control si...

Abstract

Adaptive transport format uplink signaling for data-non-associated feedback control signals. One or more dynamically selected signaling bits are added in a downlink from a base station to user equipment (UE) so that the UE can use an adaptive ''symbol space'' for uplink feedback (CQI / HARQ) signaling and know from the extra added downlink signaling bits and the MCS currently signaled in parallel how big a symbol space to use at the moment for the uplink feedback.
