摘要： Methods and apparatus related to scheduling and/or utilization of air link traffic resources are described. A peer to peer connection holds a set of multiple connection identifiers for a plurality of successive traffic slots. Corresponding to a particular traffic slot, each of the connection identifiers in the set of connection identifiers has a different priority. Short term traffic needs are considered in the use of the multiple connection identifiers being held. For example, a communications device, corresponding to a peer to peer connection which is associated with a plurality of connection identifiers having different priorities, considers the amount and/or latency requirements of data to be transmitted at any given time when selecting which connection identifier to use when transmitting a traffic transmission request for a traffic segment which is in contention.

摘要： Methods and Apparatus for communicating information, e.g., control information, e.g., in the form of a control value, between communications devices, e.g., peer to peer communications devices, are described. Positional coding is used to encode a value to be communicated and the encoded value it then transmitted on a set of communications resources with the placement of signal energy on individual ones of the resources being used to create a pattern used to convey the value to be communicated. Resources, e.g., tone-symbols, which communicate unreliable signal portions due to interference are identified and not used in the positional decoding operation as either an energy carrying tone-symbol or a non-energy carrying tone-symbol.

摘要： In an ad hoc peer-to-peer communication network between wireless devices, a high priory first receiver device is configured to perform successive interference cancellation (SIC). The first receiver device sends a first rate report signal and a second rate report signal to a first transmitter device indicating a first and second transmission rates. A connection is established between the first transmitter device and the first receiver device in which the first receiver device is the intended receiver of traffic signals from the first transmitter device. The first receiver device receives a traffic signal in a subsequent traffic channel, the traffic signal including a first traffic signal from the first transmitter device having a first traffic transmission rate not exceeding the first transmission rate. The received traffic signal also includes a second traffic signal transmitted by an interfering second transmitter device having a second traffic transmission rate not exceeding the second transmission rate.

摘要： An improved mechanism is provided that facilitates transmission of small packets within an ad hoc peer-to-peer network. A small packet is identified to a receiver within a control channel so that its lower power can be considered in an interference management protocol implemented among local peer devices. In a traffic slot, a transmitter voluntarily backs down on the transmitter power as a smaller packet will require much lower signal-to-noise ratio. This will improve the signal energy per bit per noise power density for the transmission as well as minimize the interference caused to other wireless communications happening in the same spectrum.

摘要： Various methods and apparatus relate to sharing QoS privileges between devices having a higher service level subscription and devices having lower service level subscription. QoS privileges are associated with a QoS service level which is in turn tied to devices, e.g., based on a service level subscription of the device. Devices with higher service level subscription are entitled to superior QoS privileges than the devices with lower service level subscription. In various embodiments a first device with higher QoS service level provides, to a second device having lower QoS service level, information used to obtain a QoS privilege to which the first device is entitled. Thus the second device entitled to lower QoS privileges is provided with the superior QoS privileges on a limited basis, e.g., for communicating with the first device corresponding to the higher QoS service level.

摘要： Various methods and apparatus relate to controlling access to communications resources in a wireless communications system. Various described methods and apparatus are well suited for use in a peer to peer network in which resource access control is implemented in a distributed manner and wireless terminals compete for communications resources, e.g., compete for a peer to peer traffic segment. A wireless terminal generates QoS tokens within said wireless terminal at a rate which is a function of a QoS level associated with the wireless terminal and uses a generated token to control access to a communications resource. Generated tokens within the wireless terminal may be shared among the applications of the wireless terminal.

摘要： A communications device, e.g., a mobile wireless terminal, includes a plurality of antennas having different polarization directions. The plurality of antennas includes a first antenna and second antenna which are operated in a coordinated fashion. During reception a signal received via the first antenna is subjected to a phase shift operation before being combined with a signal received via the second antenna. During transmission a signal to be communicated is subjected to a phase shift operation and the phase shifted signal is transmitted over the first antenna while the non-phase shifted signal is transmitted over the second antenna. The amount of phase shift is a function of the difference in polarization directions between the first and second antennas. The novel antenna configuration facilitates the use of the horizontal polarization direction communications between the communications device and a base station without the need for directionally positioning one or more electrical antennas.
