摘要： Systems and methodologies are described that facilitate transmitting control information in wireless networks. Portions of bandwidth can be blanked for transmitting control information, and the control information transmitters can utilize beacon symbols to convey the control information. In this regard, interference is mitigated with respect to data transmissions over the control information bandwidth. Selected frequencies of the beacon symbols in a codeword can be used to indicate the control information. The codewords can be encoded with an error control code to provide redundancy for decoding in the presence of some interference.

摘要： Techniques for sending low reuse preambles in a wireless network are described. In an aspect, a base station sends a low reuse preamble on reserved frequency resources to allow terminals to detect the base station even in the presence of strong interfering base stations. The base station generates the low reuse preamble to include a pilot portion and a data portion. The base station determines frequency resources reserved for sending low reuse preambles by base stations. The base station then sends the low reuse preamble on the reserved frequency resources, e.g., at a pseudo-randomly selected time. A terminal detects for low reuse preambles sent by the base stations on the reserved frequency resources. The terminal recovers information for a base station from a detected low reuse preamble.

摘要： For range expansion, a determination to enter range expansion may be made based on a signal strength differential for user equipment (UE) communications between a first class of base stations and a second class of base stations. If the signal strength differential is beyond a certain threshold, range expansion may be implemented. In range expansion, a signal is transmitted, on a resource coordinated with at least one of the first class of base stations, from one of the second class of base stations to the UE which could experience dominant interference from one of the first class of base stations if coordination were not performed. Transmission power may be reduced from one of the first class of base stations on that resource. The second signal may be transmitted within the region of the Physical Downlink Shared Channel.

摘要： Methods, apparatuses, and computer program products are disclosed for encoding/decoding a wireless control signal. For encoding, control bits are received and encoded with a first error control code so as to create a first set of encoded bits. The encoded bits are then encoded with a second error control code so as to create a second set of encoded bits, which are modulated as beacon tones and subsequently transmitted. For decoding, beacon tones corresponding to a set of control bits are received and subsequently demodulated so as to ascertain a set of demodulated bits. The demodulated bits are then decoded with a decoder so as to ascertain a set of decoded bits. The decoded bits are then decoded with a second decoder so as to ascertain a second set of decoded bits, which includes the set of control bits.

摘要： Techniques for sending signaling messages with beacon signals in a wireless communication network are described. In one design, a transmitter station may map a signaling message (e.g., a reduce interference request) to multiple code symbols. The transmitter station may select multiple resource elements from among a plurality of resource elements based on the multiple code symbols. In one design, each code symbol may be sent across frequency by selecting one of multiple subcarriers in one symbol period. In another design, each code symbol may be sent across time by selecting one of multiple symbol periods on one subcarrier. The transmitter station may generate a beacon signal having transmit power on the selected resource elements and no transmit power on remaining resource elements. The transmitter station may send the beacon signal to at least one receiver station.
