Abstract: System and method for assigning communications resources in a wireless communications system. A method for operating a base station comprises receiving a resource request for radio resources for a mobile station, in response to a determining that the base station will service the resource request, assigning radio resources based on the resource request and transmitting an indicator of the assigned radio resources to the mobile station, and in response to a determining that the base station will not service the resource request, returning to a normal mode of operations. The assigning of radio requests makes use of a channel tree comprised of two non-orthogonal sets of mappings between nodes of the channel tree and radio resources, with each node corresponding to at least one radio resource.

Abstract: The present invention provides a method, a system, an access terminal and an access network for transmitting a forward traffic channel at a fixed rate. In the present invention, an access terminal transmits identification information of one or more specific forward carrier links to an access network when the access terminal determines that it needs to receive one or more forward traffic channels at a fixed rate from the one or more specific forward carrier links as designated. The access network transmits one or more forward traffic channels at the fixed rate according to the received identification information. The inventive access terminal may choose to receive a forward traffic channel(s) at a fixed rate from a forward carrier link(s) of a sector(s) as designated, thereby enhancing flexibility in transmitting a forward traffic channel and improving the multiple carrier EV-DO technology.

Abstract: A wireless system sleep method, a terminal and a base station are disclosed herein. The method includes the following steps: determining, by a Base Station, an availability interval and an unavailability interval of a sleep mode for a terminal, where the availability interval and the unavailability interval are both in subframes; and scheduling, by the BS, the availability interval and the unavailability interval for the terminal. The present invention is applicable to the wireless communication field.

Abstract: In accordance with an embodiment of the present invention, a method of operating a base station includes transmitting a first control channel to a user device. The first control channel has a subframe partition index that partitions resources of an associated subframe into at least one partition. The at least one partition has a size limited to only a set of possible partition sizes.

Abstract: A method and system for data transmission unit retransmission between a data receiver and a data transmitter. A data receiver determines that there is a missing data transmission unit based on a non-acknowledgement mechanism. The data receiver transmits identification information of correctly received data transmission units which are in the same link as the missing data transmission unit to a data transmitter. The data transmitter determines a data transmission unit which needs data retransmission according to the identification information it has received, and retransmits the data transmission unit.
