摘要： A method of signaling to enable tethering among wireless devices may include receiving, at a master wireless device, assignment information from a wireless communication access point. The assignment information may indicate that the master wireless device is designated as a hotspot for a slave wireless device. The method also may include determining an availability of an open frequency band for wireless communications, communicating an enabling signal to the slave wireless and receiving a confirmation of receipt of the enabling signal. Further, the method may include determining an allocation of a wireless communication resource over the open frequency band for the master wireless device to act as the hotspot for the slave wireless device. The allocation may be based on the confirmation of receipt of the enabling signal and on a parameter requirement associated with the master wireless device acting as the hotspot for the slave wireless device.

摘要： A control method for a radio communication system, wherein a first apparatus (2) transmits a resource allocation request (SR), as well as a radio signal (SRS) used to select a radio resource, to a second apparatus (1), in response to which the second apparatus (1) selects a radio resource to be allocated to the first apparatus and transmits information of the selected radio resource to the first apparatus. Consequently, the first apparatus transmits transmission data by using the radio resource specified by the information. The method includes regulating transmission of the resource allocation requests (SR) and/or the radio signals (SRS) used to select resource when the first apparatus (2) receives a particular signal from the second apparatus (1).

摘要： A method of determining a precoder for wireless communications may include acquiring first channel information associated with a first channel between a first node (207) of a wireless communication network and a second node (209) of the wireless communication network. The first node (207) may be configured to transmit a first wireless signal in a wireless communication resource to the second node (209) via the first channel. The method may further include acquiring second channel information associated with a second channel between the first node (207) and a third node (202) of the wireless communication network. The third node (202) may be configured to receive a second wireless signal transmitted in the wireless communication resource. Additionally, the method may include determining a precoder for transmission of the first wireless signal based on the first channel information and the second channel information.

摘要： A method of device-to-device communication by a wireless device in a wireless communication network may include transmitting a first packet that includes first message data to multiple neighboring wireless devices in the wireless communication network. The method may also include receiving a second packet from one of the multiple neighboring wireless devices. The second packet may be generated by a second wireless device in the wireless communication network that is not one of the multiple neighboring wireless devices. The second packet may include second message data generated by the second wireless device and the first message data. In response to receiving the second packet, the method may further include transmitting a third packet configured to be unicast to the second wireless device. The third packet may include third message data generated by the wireless device.
