    摘要： Methods, systems, and devices are described for wireless communication. Device-to-device (D2D) communications may benefit from the use of a relay facilitating communications between mobile devices. Relays which are not power-limited, such as if the relay is connected to a power grid, may continuously monitor the communication medium. A relay may monitor D2D communications and determine a D2D pair for which to attempt to facilitate communications. The relay may identify a first message from a first mobile device to a second mobile device, and may transmit a second message to the second mobile device. The second message may be transmitted using the same resources as the first message, and may include at least a portion of the first message. The relay may receive a response from the second mobile device and may transmit information about the relay to the second device before facilitating communications between the D2D pair of mobile devices.

    摘要： A method, an apparatus, and a computer-readable medium for wireless communication are provided. The apparatus retrieves a particular number corresponding to a UE. To retrieve the particular number, the apparatus may receive the particular number through a channel request from the UE. Alternately, the apparatus may assign the particular number to the UE in order to retrieve the particular number. The apparatus determines a resource block within a coverage class based on the particular number. To determine the resource block, the apparatus maps the particular number to a resource block number within the coverage class using a hash function. The resource block number identifies the resource block. The apparatus transmits a device-specific control message to the UE using the determined resource block.

    摘要： Pilot signal transmission sequences and methods are described for use in a multi-sector cell. Pilots in different sectors are transmitted at different known power levels. In adjacent sectors a pilot is transmitted while no pilot is transmitted in the adjoining sector. This represents transmission of a NULL pilot signal. A cell NULL is also supported in which NULL pilots are transmitted in each sector of a cell at the same time. Multiple pilot signal measurements are made. At least two channel quality indicator values are generated from measurements corresponding to at least two pilot signals of different power levels. The two values are transmitted back to the base station which uses both values to determine the transmit power required to achieve a desired SNR at the wireless terminal. The wireless terminal also reports information indicating its location to a sector boundary.
