    摘要: A mobile station (110) selects an initial data rate for communication between base station (107) and mobile station (110). Mobile station (110) communicates the selected initial data rate to base station (107) through uplink (112). Base station (107) determines a difference level of interference condition experienced by mobile station (107) between a time when the initial data rate was selected by mobile station (110) and a time when base station (107) prepares to communicate to mobile station (110). Base station (107) selects a final data rate for transmission from base station (107) to mobile station (110) based on the determined difference level of interference condition. As such, the initial data rate may be modified to the final data rate while maximizing the down link capacity.

    摘要: A communication system includes a forward link from a base station to multiple mobile units, the forward link having multiple shared channels (SHCH's), multiple shared control channels (SHCCH's), and multiple dedicated pointer control channels (DPTRCH's), and utilizes HARQ error control for error detection and error correction. The mobile unit, when listening to the DPTRCH, uses a SHCCH pointed to by the DPTRCH to demodulate and decode data on the SHCH. Throughput problems may arise in the system when the mobile unit combines and decodes the wrong SHCH data, that is, SHCH data that is intended for a different mobile unit, or may incorrectly decodes SHCH data that is intended for the mobile unit. In order to improve the data throughput of the system, the systems employs a flush test and an energy detector test to prevent improperly decoded data blocks from corrupting properly decoded data blocks.

    摘要: A method in a wireless communication User Equipment (UE) includes receiving a Physical Downlink Control Channel (PDCCH) message assigning a data transmission on a Physical Downlink Shared CHannel (PDSCH), wherein the PDCCH message includes scheduling information with a first New Data Indicator (NDI) bit field for a first transport block and a second New Data Indicator (NDI) bit field for a second transport block. The UE determines one or more antenna ports for the data transmission based on the NDI bit fields of the transport blocks, before receiving the assigned data transmission on the PDSCH.

    摘要: A wireless base unit (102) supporting carrier aggregation determines a truncation time period (159, 169) in order to create a reduced subframe component (154, 164) on an additional component carrier (120) such that the truncated subframe component (154, 164) does not interfere with the control region (171, 172) of a subframe (170, 180) transmitted on an overlapping component carrier (130) by an uncoordinated second base unit (105). The wireless base unit (102) transmits the truncated subframe component (154, 164) and also transmits truncation time period information within a control region (151, 161) of an anchor carrier (110). A remote terminal (104, 108) that supports carrier aggregation searches a control region (151, 161) of a subframe (150, 160) transmitted on the anchor carrier (110) for truncation information and uses the truncation information to determine a boundary of a data region in a subframe component (154, 164) received on the additional component carrier (120).
