Method and apparatus for data and control multiplexing

摘要

System(s) and method(s) are provided for transmitting data code symbols and control code symbols spanning disparate transmission time intervals in the uplink. Data and control symbols that overlap in time-domain within a transmission time interval are multiplexed and transmitted employing resources scheduled for data transmission, whereas data and control code symbols that are not multiplexed are transmitted in respective allocated resources. Multiplexing in conjunction with localized and distributed resource scheduling preserves the single-carrier characteristics of a single-carrier frequency division multiple access system.

1. A system utilized in wireless communications, comprising:
a processor configured to:
receive an allocation of resources to transmit data code symbols and control code symbols, wherein transmission of the control code symbols occurs in a primary transmission time interval (TTI) and transmission of the data code symbols occurs in a secondary TTI, wherein said primary TTI exceeds said secondary TTI;determine whether the data code symbols and the control code symbols overlap within the secondary TTI;upon determining that the data code symbols and the control code symbols overlap within the secondary TTI, multiplex the data code symbols and the control code symbols that overlap within the secondary TTI;employ the resources allocated to transmit the data code symbols to convey the multiplexed data code symbols and control code symbols; andemploy the resources allocated to transmit the control code symbols, if the data code symbols and the control code symbols are not multiplexed; and a memory coupled to the processor to store data.
