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).

Abstract: A method of operating a wireless communication system is disclosed. The method includes configuring a user equipment (UE) for carrier aggregation with N serving cells, where N is a positive integer. The UE is scheduled to receive downlink data from M of the N serving cells at a first time, where M is a positive integer less than or equal to N. The UE provides uplink control information (UCI) for only the M serving cells.

Abstract: A method for uplink (UL) wireless backhaul communication at a wireless backhaul remote unit in a radio access network comprising receiving a configuration for radio frames and a transmission schedule through a downlink (DL) physical layer broadcast channel, wherein the transmission schedule comprises a transmission allocation for the remote unit, generating a UL data frame, wherein generating the UL data frame comprises performing forward error correction (FEC) encoding on a data bit stream to generate a plurality of FEC codewords, wherein performing the FEC encoding comprises performing Reed Solomon (RS) encoding on the data bit stream to generate a plurality of RS codewords, performing byte interleaving on the RS codewords, and performing Turbo encoding on the byte interleaved RS codewords to generate one or more Turbo codewords, wherein each Turbo codeword is encoded from more than one RS codeword, and transmitting the UL data frame according to the transmission allocation.

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: Simplified communication between user equipment and a neighboring cell not the primary cell is achieved by restricting the transmission parameters, such as bandwidth, of the neighboring cell transmission and provision of a simplified secondary baseband processor in the user equipment.
