Abstract
A method of wireless communication of a UE is provided. The UE determines K1 information bits carrying one or more CSI reports, the one or more reports including a first CSI report, K1 being an integer greater than 0. The UE selects K2 information bits from the K1 information bits, the K2 information bits excluding a part of information bits of the first CSI report, K2 being an integer greater than 0 and smaller than K1. The UE determines that the K2 information bits are in a first predetermined relationship with a threshold. The UE transmits E2 encoded bits derived from the K2 information bits in a physical up-link channel to a base station, E2 being an integer greater than 0.

A method of wireless communication of a user equipment (UE), comprising:
- determining K1 information bits carrying one or more channel state information (CSI) reports, the one or more reports including a first CSI report, K1 being an integer greater than 0;
- selecting K2 information bits from the K1 information bits, the K2 information bits excluding a part of information bits of the first CSI report, K2 being an integer greater than 0 and smaller than K1;
- determining E2 encoded bits derived from the K2 information bits to be transmitted, E2 being an integer greater than 0;
- determining a first code rate based on K2 and E2;
- determining that the first code rate is smaller than a code-rate threshold;
- and
- transmitting the E2 encoded bits in a physical up-link channel to a base station.
A method of wireless communication of a user equipment (UE), comprising:
- determining K1 information bits carrying one or more channel state information (CSI) reports, the one or more reports including a first CSI report, K1 being an integer greater than 0;
- selecting K2 information bits from the K1 information bits, the K2 information bits excluding a part of information bits of the first CSI report, K2 being an integer greater than 0 and smaller than K1;
- determining an integer M that is a maximum number of segments allowed for segmenting the K1 information bits;
- and
- dividing the K2 information bits into M segments;
- determining that each segment from the M segments of the K2 information bits has a respective size equal to or smaller than a segment-size threshold;
- and
- transmitting E2 encoded bits derived from the K2 information bits in a physical up-link channel to a base station, E2 being an integer greater than 0.
An apparatus for wireless communication, the apparatus being a user equipment (UE), comprising:
- a memory;
- and
- at least one processor coupled to the memory and configured to:
- determine K1 information bits carrying one or more channel state information (CSI) reports, the one or more reports including a first CSI report, K1 being an integer greater than 0;
- select K2 information bits from the K1 information bits, the K2 information bits excluding a part of information bits of the first CSI report, K2 being an integer greater than 0 and smaller than K1;
- determine E2 encoded bits derived from the K2 information bits to be transmitted, E2 being an integer greater than 0;
- determine a first code rate based on K2 and E2;
- determine that the K2 information bits are in a first predetermined relationship with a threshold;
- and
- determine that the first code rate is smaller than a code-rate threshold;
- and
- transmit the E2 encoded bits derived from the K2 information bits in a physical up-link channel to a base station, E2 being an integer greater than 0.
