Claim of US Patent No. 11,032,837

1. A method for use in a wireless device in a wireless communication system for transmitting uplink control information (UCI), the method comprising:obtaining UCI comprising a number of UCI bits;
mapping the UCI bits to a set of modulation symbols;
obtaining a resource configuration, wherein the resource configuration is at least indicative of:
one or more allocated resources available for transmission of the modulation symbols, and
a subcarrier allocation pattern defining allowed use of subcarriers within the one or more allocated resources,
wherein, for at least one symbol in the one or more allocated resources, the subcarrier allocation pattern defines allowed use of at least some contiguous subcarriers;
mapping the modulation symbols to the resource configuration; and
transmitting the modulation symbols using the allocated subcarriers;wherein the step of mapping the modulation symbols further comprisesselecting a resource set from the allocated resources; and
allocating subcarriers comprised in the resource set for transmission of the modulation symbols; andwherein the method further comprises:determining that the number of UCI bits is less than or equal to a number of payload bits offered by the resource set before performing the step of allocating the subcarriers; and
adapting a code rate or a modulation order to accommodate additional payload bits.
