    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.

    Abstract: User equipment (UE)—initiated accesses within a cellular network are optimized to account for cell size and to reduce signaling overhead. A fixed set of preamble parameter configurations for use across a complete range of cell sizes within the cellular network is established and stored within each UE. A UE located in a given cell receives a configuration number transmitted from a nodeB serving the cell, the configuration number being indicative of a size of the cell. The UE selects a preamble parameter configuration from the fixed set of preamble parameter configurations in response to the received configuration number and then transmits a preamble from the UE to the nodeB using the preamble parameter configuration indicated by the configuration number.

    Abstract: A method for communicating over a wireless backhaul channel comprising generating a radio frame comprising a plurality of time slots, wherein each time slot comprises a plurality of symbols in time and a plurality of sub-carriers in a system bandwidth, broadcasting a broadcast channel signal comprising a transmission schedule to a plurality of remote units in a number of consecutive sub-carriers centered about a direct current (DC) sub-carrier in at least one of the time slots in the radio frame regardless of the system bandwidth, and transmitting a downlink (DL) control channel signal and a DL data channel signal to a first of the remote units, wherein the DL data channel signal is transmitted by employing a single carrier block transmission scheme comprising a Discrete Fourier Transform (DFT) spreading for frequency diversity.

    Abstract: A transmission of information from a secondary to a primary node occurs in a plurality of transmission instances which are logical time durations. A secondary node receives an allocation of periodic transmission instances for a scheduling request indicator (SRI) and an allocation if periodic transmission instances for a sounding reference signal (SRS). In a particular transmission instance allocated for the transmission of both SRS and SRI, the secondary node transmits the SRI without transmitting the SRS if the SRI indicates a pending scheduling request; otherwise, the secondary node transmits the SRS without transmitting the SRI.
