METHOD AND APPARATUS FOR RESOURCE ELEMENT DETERRMINATION IN WIRELESS COMMUNICATIONS
Provided are a method and an apparatus for resource element determination in wireless communications. A user equipment (UE) receives first signaling that indicates a first resource element (RE) set and transmits a code block set and a first bit block in only an RE subset within the first RE set. The first RE set is reserved for the code block set, and the RE subset is determined based on a number of bits of the code block set. A control information block comprises the first bit block, and a first integer is based on numbers of bits. A second integer is based on a number of all REs in the RE subset. A number of coded modulation symbols per layer used for transmitting the first bit block in the RE subset is not greater than the first integer and not greater than the second integer.
