UL ACK/NACK for inter-radio access technology carrier aggregation

摘要

A method is disclosed that includes, for each of a multiplicity of subframes to be communicated using a first radio access technology, determining a first number of bits used for first feedback information corresponding to a first communication effected using the first radio access technology and a second number of bits used for second feedback information corresponding to a second communication effected using a second radio access technology. The method further includes, using only the first radio access technology, communicating the multiplicity of subframes, wherein for each of the multiplicity of subframes, included in the subframe are the first feedback information using the determined first number of bits and the second feedback information using the determined second number of bits. Apparatus, program products, and computer programs are also disclosed.

1. A method comprising:
for each of a plurality of subframes to be communicated using a first radio access technology, determining a first number of bits used for first feedback information corresponding to a first communication effected using the first radio access technology and a second number of bits used for second feedback information corresponding to a second communication effected using a second radio access technology; and using only the first radio access technology, communicating the plurality of subframes, wherein for each of the plurality of subframes, included in the subframe are the first feedback information using the determined first number of bits and the second feedback information using the determined second number of bits, wherein determining further comprises; determining whether the first number of bits used for the first feedback information is non-zero or is non-zero for a second pair of subframes; in response to determining the first number of bits used for the first feedback information is non-zero for the second of the pair of subframes, determining the second number of bits used for the second feedback information in the second of the pair of subframes is non-zero; and in response to determining the first number of bits used for the first feedback information is zero for the second of the pair of subframes, determining the second number of bits used for the second feedback information in the second of the pair of subframes is zero.
