    Abstract: A transmission of information from a secondary to a primary node occurs in a plurality of N logical time durations. The transmission from the secondary to primary node in a wireless network is obtained using an orthogonal covering sequence and a second sequence. Embodiments of the present invention mitigate interference by calculating a first orthogonal covering (OC) index and a second OC Index from an indicator received from a serving base station (NodeB). A first index n1 is derived and a second index n2 is derived using the first index n1. A first orthogonal covering (OC) index and a first cyclic shift (CS) is determined using the derived index n1. A second OC and a second CS is derived using the derived index n2. A first slot of a subframe is generated using the OC indexed by the first OC index and the first CS and a second slot of the subframe is generated using the OC indexed by the second OC index and the second CS.

    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: A method for allocating resources for a scheduling request indicator (SRI) is disclosed. An SRI cycle period for use by user equipment (UE) within a cell is transmitted from a NodeB in a cell to UE within the cell. The NodeB transmits a specific SRI subframe offset and an index value to the particular UE within the cell. The specific SRI subframe offset and the index value enable the UE to determine a unique combination of cyclic shift, RS orthogonal cover, data orthogonal cover, and resource block number for the UE to use as a unique physical resource for an SRI in the physical uplink control channel (PUCCH).
