Patent number: 11082956Abstract: In one embodiment, a method is performed by a base station in a wireless network. The method includes receiving from a user device a request to reconfigure already-active uplink semi-persistent scheduling (SPS). The already-active uplink SPS grants the user device a resource block allocation (RBA) and a modulation and coding scheme (MCS) for periodic uplink transmissions. The already-active uplink SPS includes a time-interval parameter, the time-interval parameter specifying a time interval between the periodic uplink transmissions. The request includes information related to a proposed adjustment of the time-interval parameter. The method further includes reconfiguring the already-active uplink SPS. The reconfiguring includes modifying the time-interval parameter based, at least in part, on the information.Type: GrantFiled: March 18, 2020Date of Patent: August 3, 2021Assignee: Mosaid Technologies IncorporatedInventor: Khiem Le

Patent number: 9781199Abstract: A method, system and apparatus are provided for performing peer-to-peer (P2P) data sharing operations between user equipment (UE) devices in a wireless-enabled communications environment. A first client node comprises content data and operates in a server peer mode to provide content data. A second client node submits a request to a P2P application server (P2P AS) for the content data. In response, the P2P AS provides the address of the first client node to the second client node. The second client node then uses the provided address to submit a request to the first client node to provide the content data. The first client node accepts the request and then provides the content data to the second client node.Type: GrantFiled: December 28, 2015Date of Patent: October 3, 2017Assignee: BlackBerry LimitedInventors: Noun Choi, Wei Wu, Khiem Le

Patent number: RE46125Abstract: A method of relocating the header compression context in a packet network which transmits packets having compressed headers. A connection is established between a mobile terminal and a first network entity and context information used with compression and decompression of the headers of the packets is stored at the mobile terminal and the first network entity. The context information updating is stopped in the mobile terminal and in the first network entity and after that, a snapshot of the compression and decompression context information is taken and stored in the first network entity. The connection between the first network entity and the mobile terminal is changed to a connection between the mobile terminal and a second network entity. The context information snapshot stored by the first network entity is transferred to the second network entity to be stored therein as the context information of the second network entity.Type: GrantFiled: November 6, 2008Date of Patent: August 23, 2016Assignee: Core Wireless Licensing S.a.r.l.Inventors: Juha Kalliokulju, Atte Lansisalmi, Yousuf Saifullah, Khiem Le
