摘要： Certain aspects of the present disclosure provide techniques and apparatus for operating in a television white space (TVWS) network. One example method generally includes receiving, at an apparatus, a message with a field indicating a current version of an unused frequency spectrum map (e.g., a white space map (WSM)), the unused frequency spectrum map indicating channels usable for wireless communications; determining whether the current version of the unused frequency spectrum map is different than a previous version of the unused frequency spectrum map; and using a channel for wireless communications based on the determination. Another example method generally includes accessing a database of available channels for a current location of an apparatus via a neighboring portable or fixed enabling apparatus and enabling one or more portable dependent apparatuses for the wireless communications via one or more of the available channels.

摘要： A system and method for wireless devices to efficiently receive communications by transmitting and receiving specialized beacon messages. Particularly, a wireless device may await reception of a synchronizing beacon message from a transmitting device. A relative position identifier within the synchronizing beacon message may then allow the wireless device to anticipate future beacon message transmissions and to synchronize its reception pattern with the transmitter. In this manner the wireless device need only receive and decode beacon messages germane to its operation.

摘要： Methods, systems, and/or devices are provided that permit data transmissions over unused television channels. An unused channel within a television broadcast frequency spectrum is first identified. A downclocked waveform (for data transmission) is then generated by applying a factor to a clock that causes a waveform bandwidth to be reduced from a first bandwidth to a second bandwidth, wherein the second bandwidth of the downclocked waveform is less than a channel bandwidth for the identified unused channel. The downclocked waveform may then be configured so that it coexists with a larger waveform having a third bandwidth that is greater than the channel bandwidth. The downclocked waveform is then wirelessly transmitted from the transmitter device over the identified unused channel.

摘要： Certain aspects of the present disclosure provide techniques and apparatus for managing transmit power in a television white space (TVWS) network. By managing transmit power as described herein, medium re-use may be improved in such a network, and unfair usage problems may be alleviated. One example method generally includes receiving, from an apparatus, a message with an indication of a highest transmit power used by the apparatus for transmitting data frames; and determining that the apparatus is a dominant interferer based, at least in part, on the highest transmit power. Another example method generally includes receiving, from an apparatus, a control or management message with a first indication of a first transmit power used by the apparatus for transmitting data frames; and determining that the apparatus is a dominant interferer based, at least in part, on the first transmit power.

摘要： Certain aspects of the present disclosure provide techniques and apparatus for managing transmit power in a television white space (TVWS) network. One example method generally includes transmitting a sequence of request-to-send (RTS) messages at different transmit power levels to an apparatus and determining if a clear-to-send (CTS) message was received in response to at least one of the RTS messages corresponding to a particular one of the transmit power levels. Another example method generally includes receiving, at a first apparatus from a second apparatus, a packet that cannot be decoded by the first apparatus; determining at least one of a time or a duration corresponding to the packet; transmitting a query with an indication of the at least one of the time or the duration; and receiving a message from the second apparatus in response to the query, the message identifying the second apparatus as a source of the packet.

摘要： Certain aspects of the present disclosure provide techniques and apparatus for managing group identifiers (IDs) in multiuser multiple-input multiple-output (MU-MIMO) schemes to ensure that the group ID maps to the same assigned spatial stream position for a particular station (STA), for either Direct Link Service (DLS) or downlink (DL) MU-MIMO transmissions. One example method generally includes transmitting, form a first apparatus to a second apparatus, a message requesting assignment of a group ID identifying a group of apparatuses for receiving MU transmissions; and receiving, from the second apparatus, an indication of the assigned group ID, such that spatial stream assignments for the group of apparatuses are the same between the first and second apparatuses, the spatial stream assignments corresponding to the assigned group ID.
