摘要： A method, an apparatus, and a computer program product for wireless communication are provided. The apparatus generates a codeword, determines at least one puncture to the codeword based on allowing a legacy receiver to decode the codeword without knowledge of the at least one puncture, replaces each of the at least one puncture with a pilot, and transmits the codeword. The apparatus may also generate an IEEE 802.11 codeword having pilots in a first set of subcarriers, and puncture the codeword with additional pilots unknown to a legacy receiver in a second set of subcarriers. Accordingly, when an original set of pilot symbols is insufficient or inappropriately placed in a resource structure, a codeword may be transmitted with a new pilot structure capable of being decoded by legacy receivers not aware of the new pilot structure.

摘要： A transmission initiation interval timing structure is used in combination with a lower layer timing structure, e.g., physical layer timing structure. A device selects a subset of packet transmission initiation intervals and then limits initiation of packet transmission to those intervals thereby reducing the potential for collisions. Packet transmission may occur outside the initiation interval in which the transmission is initiated. In some embodiments, packet transmission length is intentionally limited to sizes which can be transmitted in a fraction of the amount of time the physical layer allows a single device to continuously transmit, e.g., in an amount of time which is equal to or less than the duration of a packet transmission initiation interval. This increases the probability that multiple devices will be able to successfully transmit small packets at short intervals on a regular basis even when carrier sensing techniques are used.

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, 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.
