Abstract: A method and system are provided having an uplink control structure and a pilot signal having minimal signal overhead for providing channel estimation and data demodulation in a wireless communication network. The uplink control structures enable mobile terminals to communicate with corresponding base stations to perform various functions including obtaining initial system access, submitting a bandwidth request, triggering a continuation of negotiated service, or providing a proposed allocation re-configuration header. A dedicated random access channel is provided to communicatively couple the base station and the mobile terminal so that the mobile terminal can select a random access signaling identification. A resource request is received at the base station to uplink resource information from the mobile terminal and an initial access information request is received from the mobile terminal to configure the base station connection. Pilot signals with varying density configurations are provided to include low density symbol patterns for multiple contiguous resource blocks and high density symbol patterns for single resource blocks.

Abstract: To effectively and efficiently provide control information, a broadcast pointer channel (BPCH) may be used to identify the type and perhaps relative location of control information that is being provided in a given frame structure, such as a sub-frame, frame, or superframe. A sub-frame (or like framing entity, such a frame or superframe) may have a BPCH and a corresponding system control information segment in which control information may reside. The system control information segment may have any number of control information blocks, wherein each control information block that is present may correspond to a particular type of control information. The BPCH is used to identify the type of control information that is present in a corresponding system control information segment, and if needed or desired, the relative locations of the various control information.

Abstract: A method for transmitting data in a multiple-input-multiple-output space-time coded communication using a mapping table mapping a plurality of symbols defining the communication to respective antennae from amongst a plurality of transmission antennae and to at least one other transmission resource. The mapping table may comprise Alamouti-coded primary segments and may also comprise secondary segments, comprising primary segments. The primary segments in the secondary segments may be defined in accordance to an Alamouti based code pattern applied at the segment level to define a segment-level Alamouti based code.

Abstract: Methods and systems are described that are suitable for channelization, in particular, but not limited to, the IEEE 80216.m telecommunications standard. For a time-frequency resource, physical sub-carriers for each of one or more zones in the time-frequency resource are assigned to one or more zones having a respective type of transmission. At least one zone is allocated for a type of transmission using localized sub-carriers. The physical sub-carriers assigned to each zone are permuted to map to logical sub-carriers. Groups of resource blocks are formed, in which each resource block includes at least one logical sub-carrier for each of the one or more zones. The information defining the groups of resource blocks for each of the one or more zones can then be transmitted to a user. The information may be in the form of a zone configuration index.

Abstract: Transmission of uplink control message for a wireless system. The uplink control message may be encoded according to one of multiple possible schemes. The choice of encoding scheme may be made based on the control message size and/or based on the available transmission resources and/or based on the detection scheme used on the receiving end. A modulation scheme may also be selected based on such factors. CDM may be used for certain control messages. Block code encoding, such as Reed-Muller encoding may be used for certain control messages. Different transmission resources may be allocated for different control message uses. The encoding specifics may be selected to obtain a certain hamming distance and/or size of the encoded message or based on other factors.
