Publication number: 20180176869Abstract: In a radio access network, user equipment (UE) is to encode signaling for sector-sweep transmission to a base station via a plurality of directional beams in a millimeter-wave radio band over a random-access shared channel during at least one contention period, and determine a transmission power setting for the directional transmission. The transmission power setting is based on a targeted received signal characteristic to be achieved at the base station using a selected beam direction, and the transmission power setting is determined based on transmission parameters of the UE and reception parameters of the base station, and on channel characteristics. The UE is to initiate transmission of the signaling using the transmission power setting for the plurality of directional beams, wherein the signaling is transmitted to be received according to a targeted received signal characteristic to be achieved at the base station.Type: ApplicationFiled: December 19, 2016Publication date: June 21, 2018Inventors: Ehsan Aryafar, Sarabjot Singh, Wook Bong Lee, Jing Zhu, Shu-Ping Yeh, Nageen Himayat, Shilpa Talwar

Patent number: 9949294Abstract: A client station (STA), when operating in a wireless network, receives data sent by an access point (AP) on a first channel comprising at least one subchannel. During reception of the data on the first channel, the STA monitors channel availability of an additional set of one or more subchannels. In response to a detected availability of at least one newly-available subchannel, the STA sends at least one notification to the AP identifying STA-side availability of the newly-available subchannel(s). The STA subsequently receives data from the AP on the newly-available subchannel(s), which is sent in response to the at least one notification. The AP, when communicating data to the STA, receives the at least one notification from the STA and, in response thereto, initiates data transmission on one or more of the newly-available channel(s).Type: GrantFiled: December 18, 2015Date of Patent: April 17, 2018Assignee: Intel CorporationInventors: Ehsan Aryafar, Minyoung Park, Ping Wang, Shilpa Talwar
