Multiplexing Logical Channels in Mixed Licensed and Unlicensed Spectrum Carrier Aggregation
First Claim
1. An apparatus, comprising:
- at least one processor; and
at least one memory storing a computer program;
in which the at least one memory with the computer program is configured with the at least one processor to cause the apparatus to at least;
utilize downlink control signaling to associate at least a first logical channel or radio bearer with a first component carrier in a licensed frequency band and to associate at least a second logical channel or radio bearer with a second component carrier in an unlicensed frequency band; and
utilize the associations to control which uplink data is sent on the first and on the second component carriers by multiplexing the uplink data on the at least first and the at least second logical channels or radio bearers.

Abstract
Downlink control signaling from a network to a user equipment UE associates at least a first logical channel or radio bearer with a first component carrier in a licensed frequency band and associates at least a second logical channel or radio bearer with a second component carrier in an unlicensed frequency band. The UE uses the associations to select which uplink data is sent on the first and on the second component carriers by multiplexing the uplink data on the at least first and the at least second logical channels or radio bearers. By example the downlink control signaling may be a MAC control element in a RRC_Connection_Reconfiguration message which semi-statically defines a multiplexing allowance for each of the logical channels or radio bearers. An example MAC control element has an information tuple giving the association and multiplexing status per channel/bearer. Certain embodiments also adapt transmit power scaling for licensed/unlicensed band operation.
