  • Publication number: 20110205988
    Abstract: A base station is provided. The base station includes transmit path circuitry that generates an uplink grant using an uplink multiple-input multiple-output (MIMO) downlink control information (DCI) format. The uplink MIMO DCI format includes a modulation and coding scheme (MSC) field having an MCS value for each of two transport blocks. The transmit path circuitry transmits the uplink grant to a subscriber station. For a given transport block, a combination of the MCS value corresponding to the transport block and a number positive integer of physical resource blocks allocated to the subscriber station (N_PRB) indicates whether the transport block is disabled.

  • Patent number: 7948941
    Abstract: A method and apparatus using Virtual Circuit Switching (VCS) in a new scheme are provided for allocating and employing resources by combining Circuit Switching (CS) and Packet Switching (PS), in which a base station allocates resources of a dedicated channel using the CS to a user and then transmits data on the dedicated channel. When data is not transmitted to the user, the base station allocates the allocated dedicated channel resources for resources of a shared channel and transmits data of a different user. Therefore, system capacity can be increased and a waste of communication resources can be minimized in a wireless communication system for frequently transmitting a small amount of traffic that is sensitive to a delay time.
