摘要： A method, a computer program product, and an apparatus are provided. In one configuration, the apparatus transmits a first broadcast signal including information indicating an intention to use a unicast resource for a broadcast. In addition, the apparatus transmits a second broadcast signal in the unicast resource. In another configuration, the apparatus, which is a first wireless device, receives a first broadcast signal from a second wireless device including information indicating an intention to use a unicast resource for a broadcast. In addition, the apparatus receives a first scheduling signal from the second wireless device in a scheduling resource. The first scheduling signal is for indicating a second intention to use the unicast resource for transmitting a second broadcast signal. Furthermore, the apparatus refrains from transmitting a second scheduling signal in the scheduling resource in response to the first scheduling signal.

摘要： Methods and apparatus for use in a wireless system are described where initiation of packet transmission is constrained in accordance to control actual packet transmission in a manner that reduces contention and possible collisions beyond that provided by lower layer resource contention mechanisms, e.g., 802.11 carrier sensing and/or transmission back-off timing mechanisms. Through higher level, e.g., MAC constraints, on packet transmission initiation, an air interface which employs carrier sensing can be used and controlled in a manner which reduces collisions and interference in applications where small packets, e.g., packets which can be transmitted in a fraction of the maximum permitted transmission time. The methods allow small packets in such systems to be transmitted on a periodic or semi-periodic basis in many cases.

摘要： Methods and apparatus for allocating traffic contention resource units in a wireless communications system in which decisions are made in a distributed manner are described. A wireless communications device, corresponding to a link, self allocates resource units for traffic contention. Decisions regarding initially acquiring resources, relinquishing acquired resources, and/or acquiring additional resources for traffic contention are based on detected levels of network congestion and/or detected changes in network congestion. A wireless communications device detects a level of network congestion and determines a number of resource units to acquire for traffic contention based on the detected level of network congestion.

摘要： A method, an apparatus, and a computer program product for wireless communication are provided in which information indicating a partitioning between uplink and downlink resources is received, and communication with an access point to determine at least one of whether a downlink resource will be used for uplink or whether an uplink resource will be used for downlink is performed. Accordingly, a synchronous network may be provided where partitioning of uplink-downlink resources may be dynamically selected, which is more efficient than a synchronous network where uplink-downlink resource partitioning is global and semi-static.

摘要： Various embodiments are directed to methods and apparatus for mobile device position determination and the efficient communication of mobile device position related information. In different areas different types of reference signals may be available to be used by a mobile device for position determination. Some types of references signal may be well suited for short range in an indoor environment, e.g., audio signals, Bluetooth signals and Wi-Fi signals, while other types of signals may be well suited for an outdoor environment, e.g., GPS signals and cellular base station signals. Different types of signals may facilitate different possible resolution accuracies for a position determination. In various embodiments, in different areas within a geographic coverage region, different sets of reference signals are available to be used by a mobile wireless device to determine its position. In some embodiments, different position determination resolutions are used in different area as a function of the reference signal type which is available.

摘要： Methods and apparatus are described which increase the probability and/or frequency that devices with comparatively faster clocks in a network than other devices in the network will transmit beacon signals are described. As a result, devices with faster clocks will tend to drive system synchronization to convergence faster than if all devices transmitted beacons at the same rate, thus facilitating more reliable maintenance of system synchronization since the devices with faster clocks will tend to transmit more frequently.

摘要： A method, a computer program product, and an apparatus for wireless communication are provided. The apparatus transmits a first peer discovery signal with a first periodicity/temporal frequency in a first set of peer discovery resources. The apparatus determines an energy on an allocated peer discovery resource of a second set of peer discovery resources. The apparatus refrains from transmitting a second peer discovery signal in the second set of peer discovery resources when the energy is greater than a threshold. The apparatus transmits the second peer discovery signal in the second set of peer discovery resources with a second periodicity/temporal frequency less than the first periodicity/temporal frequency when the energy is less than the threshold. The apparatus may utilize the first set of peer discovery resources every period and the second set of peer discovery resources once every N periods in which once every N periods is the second periodicity.
