METHODS OF UPLINK CHANNELIZATION IN LTE

摘要

Slot-level remapping physical uplink control channels into two resource blocks, respectively located at two slots of a subframe, are generally adapted to a 3GPP LTE physical uplink. ACK/NAK resource blocks may be applied by the extended cyclic prefix, adapted to a complex 3GPP LTE physical uplink where mixed resource blocks (where the ACK/NAK and CQI channels coexist) may be applied by the normal cyclic prefix, and adapted to a complex 3GPP LTE physical uplink where mixed resource blocks (where the ACK/NAK and CQI channels coexist) may be applied by the extended cyclic prefix.

1. A method for transmitting uplink control information, the method comprising:
determining a cyclic shift and an orthogonal cover for transmitting uplink control information based on a first parameter, n′(ns); and transmitting the control information using the determined cyclic shift and orthogonal cover, wherein, when ns mod 2=1 and nPUCCH(1)n′(ns)=└h/c┘+(h mod c)·N′/ΔshiftPUCCH,where:h=(n′(ns−1)+d)mod(cN′/ΔshiftPUCCH),where ns is an index of a slot, nPUCCH(1) is a resource index for the physical uplink control channel, Ncs(1) is a number of cyclic shifts used for the physical uplink control channel in the resource blocks, d is a predetermined parameter, ΔshiftPUCCH is a parameter signaled by a higher layer, N′ is an integer selected based upon nPUCCH(1), andc={3fornormalcyclicprefix2forextendedcyclicprefix.
