Abstract
Differential Measurement Reporting is performed by a user equipment (UE) in a communication system. The user equipment (UE) includes a transceiver configured to receive quantities representing the quality of the transmission of the communication system to be reported and to measure the quantities to be reported. If more than two measured quality values are to be reported and are within a value set of a predefined codebook of differential values, fewer feedback bits, which are used for representing the measured quality values, are sent from the user equipment (UE), or an increase in resolution of the reported values occurs while maintaining the same number of feedback bits.

A method for Improving Differential Encoding based Measurement Reporting for Transmission between a user equipment (UE) in a wireless communication system wherein the user equipment (UE) comprising a transceiver configured to receive quantities representing a quality of a transmission of the wireless communication system, the quantities are reported, wherein, the user equipment (UE) measures the receive quantities by performing operations comprising:
- determining more than two measured quality values are reported and are within a value set of a predefined codebook of differential values, in response to determining, a reducing a number of feedback bits sent from the user equipment (UE), the feedback bits representing the measured quality values is proceeded;
- wherein the user equipment (UE) sends a maximum value of the number of feedback bits coded and sends a minimum value among number of values to be reported, wherein the wireless communication system determines a number of levels in between the maximum value and the minimum value among the quality values to be reported and generates a reduced feedback codebook for decoding remaining values based on its prior knowledge of the number of levels between the maximum values and the minimum values in an original codebook user equipment (UE);
- and generating the same reduced feedback codebook based on its prior knowledge of the number of levels between the maximum values and the minimum values in the original codebook and sending the remaining measured quality values by encoding them with reduced number of bits according to the reduced feedback codebook.
An apparatus for Differential Measurement Reporting performed by a user equipment (UE) in a wireless communication system, the apparatus comprising a wireless transceiver, a processor coupled with a memory in which computer program instructions are stored, said instructions being configured to, when executed by the processor, cause the apparatus to improve Differential Encoding based Measurement Reporting for Transmission between the user equipment (UE) in the wireless
- communication system wherein the user equipment (UE) includes the wireless transceiver configured to receive quantities representing a quality of a transmission of the wireless communication system, the quantities are reported and wherein the user equipment (UE) measures the receive quantities by performing operations comprising:
- determining more than two measured quality values are reported and are within a value set of a predefined codebook of differential values, in response to determining, initiating a reduction of a number of feedback bits sent from the user equipment (UE), the feedback bits representing a presentation of the measured quality values;
- and wherein the user equipment (UE) sends a maximum value of the number of feedback bits coded and sends a minimum value among number of values to be reported, wherein the wireless communication system determines a number of levels in between the maximum value and the minimum value among the quality values to be reported and generates a reduced feedback codebook for decoding remaining values based on its prior knowledge of the number of levels between the maximum values and the minimum values in an original codebook user equipment (UE);
- and generates the same reduced feedback codebook based on its prior knowledge of the number of levels between the maximum values and the minimum values in the original codebook and sends the remaining measured quality values by encoding them with reduced number of bits according to the reduced feedback codebook.
