System and method for the placement of rank information in a physical uplink shared channel

摘要

A wireless communication network comprising a plurality of base stations capable of wireless communication with a plurality of subscriber stations within a coverage area of the network, wherein at least one of the plurality of base stations is capable of selecting two or more orthogonal frequency-division multiplexing (OFDM) symbols in a subframe of a physical uplink shared channel, the two or more OFDM symbols are selected starting from the bottom of the physical uplink shared channel in a bottom-up manner, and repeating one or more rank information (RI) coded bits in each of the selected two or more OFDM symbols.

主权项

1. A method in a user equipment (UE) for transmitting control information and user data in a communication system, the method comprising:
modulating encoded rank information bits and encoded uplink (UL) data based on a corresponding modulation scheme; mapping modulated rank information and at least one modulated UL data in a subframe of a physical uplink shared channel, the subframe comprising two slots, each slot comprising a reference signal; and transmitting the subframe including the rank information and the UL data, wherein the modulated rank information is mapped to a Single Carrier Frequency Division Multiplexing Access (SC-FDMA) symbol that is separated from the reference signal by at least one symbol comprising hybrid automatic repeat request acknowledgment information, and wherein some of the modulated UL data is mapped to the SC-FDMA symbol that is separated from the reference signal by at least one symbol.
