Abstract
Transmission of information in a wireless network is performed by allocating a channel from a transmitter to a receiver. The channel has at least one time slot with each time slot having a plurality of symbols. Each slot contains at least one reference symbol (RS). As information becomes available for transmission, it is classified as prioritized information (PI) and other information. One or more priority symbols are generated using the digital samples of the priority information. Other symbols are generated using the other data. Priority symbols are transmitted on the channel in a manner that separation of priority symbol(s) and a reference symbol does not exceed a time duration of one symbol. For example, Rank Indicator (RI) is transmitted using symbol k, ACKNAK is transmitted using symbol k+1; and the reference signal (RS) is transmitted using symbol k+2, wherein symbols k, k+1, and k+2 are consecutive in time. The other symbols are transmitted in available locations.

Claim
1. A method for transmitting in a wireless network, comprising:
transmitting a Rank Indicator (RI) using symbol k; transmitting an ACKNAK using symbol k+1; and transmitting a reference signal (RS) using symbol k+2, wherein symbols k, k+1, and k+2 are consecutive in time.
2. The method of claim 1, further comprising:
transmitting the ACKNAK using symbol k+3; and transmitting the Rank Indicator (RI) using symbol k+4, wherein symbols k, k+1, k+2, k+3, and k+4 are consecutive in time.
3. The method of claim 2; further comprising
encoding physical uplink shared channel (PUSCH) data using a turbo encoder; and transmitting the encoded PUSCH data using symbols k?1 and k+5, wherein symbols k?1, k, k+1, k+2, k+3, k+4, and k+5 are consecutive in time.
