摘要： A wireless communications device transmits during a first time using a single tone and during a second time using a plurality of tones. The wireless communications device uses linear power amplification for transmitting multi-tone signals and non-linear power amplification for transmitting at least some single tone signals. In some embodiments a linear amplification range on a first amplifier's characteristic curve is used for the linear amplification and a non-linear amplification range on the first amplifier's characteristic curve is used for the non-linear amplification. Filtering subsequent to the amplification is controlled to accommodate the type of amplification being used. In some embodiments, the decision as to whether to use linear amplification or non-linear amplification is a function of whether the intended transmitted signal is to be a single tone signal or a multi-tone signal. In some embodiments, the decision is also a function of intended range.

摘要： Aspects relate to mitigating interference in a communication network that does not employ a centralized scheduler. A transmission sent on a subset of resources is evaluated to determine a number of communication pairs that have selected that subset of resources on which to transmit. If there are a large number of communication pairs transmitting on that subset, the transmission is ignored by a receiving device. The number of degrees of freedom that contain energy on the subset is evaluated to determine if an expected number of degrees of freedom that should have energy is met or exceeded. If the expected threshold number is met or exceed, the transmission is decoded by the receiving device, else the transmission is not decoded.

摘要： A first wireless communications device includes a wide area network (WAN) interface and a peer to peer interface. The first device discovers the presence of a second wireless communications device via a peer discovery signal, received via its peer to peer interface. The second device has been transmitting, e.g., periodically, certain information, e.g., its location and/or shopping preferences, to a node within the WAN. The detected first signal triggers an application alert in the first device. The first device recovers past information about the second device through a second signal received via its WAN interface. The first device uses information communicated in the first signal, e.g., device identifier information, and information communicated in the second signal, e.g., past location and/or shopping information, to generate a targeted message for the second device. The first device communicates the targeted message via its peer to peer interface in a peer to peer traffic channel.

摘要： Methods and apparatus supporting enhanced discovery operations in peer to peer networks are described. Peer discovery, based on direct peer to peer discovery between two mobile nodes can be somewhat limited, e.g., due to power limitations, processing power, and/or channel conditions. An access point, e.g., base station, monitors for and receives peer discovery signals conveying a set of identifiers from a wireless communications device. The access point retransmits at least one identifier in the set in a wireless peer to peer communications channel. Thus the access point effectively extends the peer discovery range for wireless communications devices utilizing the peer to peer network. Wireless communications devices can monitor for and recover the rebroadcast peer discovery signals from access points. Thus, via access point signaling a wireless communications device can be made situationally aware of other devices of interest which would be otherwise outside its discovery detection range.

摘要： Methods and apparatus for processing discovery signals (113) and/or generating alerts based on received discovery signals (502) are described. In at least some embodiments, alert signal generation (216) is performed on a selective basis in response to received discovery signals. In at least some embodiments a user is given at least some control over alert generation with the user being able to indicate types of signals which should not trigger generation of an alert, the minimum permitted frequency of particular alerts (712) or types of alerts (714) and/or time or location constraints which are considered when a device determines whether or not to generate an alert in response to a received discovery signal. While user control of discovery signal processing and alert generation are provided, automatic control or adjustment of discovery signal processing and alert generation may also be implemented or the automatic control may be implemented as an alternative to the user control.

摘要： Methods and apparatus related to partitioning traffic segments are described. An access router, having concurrent connections with two access terminals and desiring to transmit traffic signals to the two access terminals in the same traffic segment, partitions a traffic segment. The partition is such that a first portion of the traffic segment is allocated to a first access terminal and a second portion of the traffic segment is allocated to the second access terminal. Control information, e.g., identifying partition portion assignments, data rate and/or coding information, is also communicated in the traffic segment as in-band control signaling. An access terminal, to which some of traffic signals are directed, receives and recovers the in-band control signaling, identifying its allocated partition portion of the traffic segment and identifying data rate and/or coding information used. The access terminal receives the traffic segment signals in its allocated partition portion and recovers the traffic information.

摘要： Methods and apparatus for making communications decisions are described. In some embodiments, a method includes recovering a quality of service level from a transmission request response signal and making a decision whether or not to transmit traffic data based on the recovered quality of service level. In other embodiments a method includes recovering a first quality of service level from a first transmission request response signal which is in response to a first traffic transmission request signal, and making a decision, based on the recovered first quality of service level, whether or not to transmit a second transmission request response signal in response to a second traffic transmission request signal. In some embodiments, the phase of the transmission request response signal is used to communicate the quality of service level. The device transmitting the transmission request response may also transmit pilots which can be used as phase reference signals.

摘要： Methods and apparatus for supporting multiple modes of communication operation, e.g., with different parameters and/or frequency bands being used in the different modes of operation are described. One or more adjustments are made based on a signal or signals received in a first frequency band from a second communications device, e.g., an access router with reliable timing. The communications device selects between and operates in either the first frequency band, e.g., a WAN frequency band, or in a second frequency band, e.g., a LAN frequency band. The WAN and LAN frequency bands may be non-overlapping. One or more parameters used in the second frequency band have a predetermined relationship to one or more parameters used for communications in the first frequency band making the adjustment based on the signal received in the first frequency band relevant and useful to support communications in the second frequency band.

摘要： Methods and apparatus for supporting peer to peer communications are described. A peer to peer communications device uses both wide area network (WAN) uplink and downlink communications air link resources for peer to peer signaling. During an uplink share mode of operation a peer to peer wireless terminal uses a wide area network uplink communications band to communicate peer to peer signals, and the peer to peer wireless terminal implements a first transmission power control function. During a downlink share mode of operation, the peer to peer wireless terminal uses a wide area network downlink communications band to communicate peer to peer signals, and the peer to peer wireless terminal implements a second transmission power control function. The second power control function is different from the first power control function.

摘要： Methods and apparatus for supporting the communication of an information stream using an individual polarization type are described. For example, a first data stream is communicated from a base station sector transmitter using horizontal polarization signals and a second data stream is communicated using vertical polarization signals. A mobile wireless communications device, employing a plurality of dipole antennas associated with different direction polarizations, e.g., a first direction horizontal polarization dipole antenna, a second direction horizontal polarization dipole antenna and a vertical polarization dipole antenna, multiple receiver modules, and a combiner module, facilitates the recovery of horizontal polarization signals without the need for azimuth antenna orienting or repositioning, and also facilitates the recovery of vertical polarization signals. The first data stream associated with horizontal polarization may be, and sometimes is, transmitted concurrently with the second data stream associated with vertical polarization using the same time/frequency air link resources, e.g., segment.
