    摘要: Techniques for scheduling users for transmission on the uplink in a wireless communication system are described. A cell may perform interference cancellation for uplink transmissions and may observe lower effective noise and interference due to interference cancellation. The lower effective noise and interference may allow the cell to operate with a higher effective target load, which may support a higher overall throughput for the cell. In one design, an effective target load for a cell using interference cancellation may be determined, e.g., based on a target rise-over-thermal (RoT) for the cell and an interference cancellation efficiency factor. An available load for the cell may be determined based on the effective target load, which may be higher than a target load for the cell without interference cancellation. Users in the cell may then be scheduled for transmission on the uplink based on the available load.

    摘要: Systems and methodologies are described that facilitate providing uplink inter-cell interference cancellation. A radio network controller can receive measurement reports in order to identify non-serving nodes that are receiving interference from user equipment. Based on evaluation of such measurement reports, an interference message can be communicated to a Node B, wherein such measurement report can include information that allows the Node B to cancel or terminate the interference caused by such identified user equipment.

    摘要: Methods and apparatuses are provided for uplink MIMO transmissions in a wireless communication system. In particular, a primary stream (610) may be utilized to carry a primary data channel E-DPDCH (624), and a secondary stream (612) may be utilized to carry a secondary data channel S-E-DPDCH (620). Further, the primary stream (610) may be precoded utilizing a primary precoding vector, and the secondary stream (612) may be precoded utilizing a secondary precoding vector, with coefficients orthogonal to those of the primary precoding vector.

    摘要: One feature provides for an apparatus, system, and method for enabling softer handover by a user equipment in a non-dedicated channel state, such as Cell_FACH state. A user equipment communicates with a base station via a first sector of the base station, and receives a preamble signature partition list. The user equipment determines that a second sector of the base station is available for softer handover, and selects a preamble signature from the preamble signature partition list corresponding to a softer handover configuration associated with the first sector and the second sector. The user equipment may then transmit a softer handover initiation message that includes the preamble signature while in a non-dedicated channel state, such as Cell_FACH.

    摘要: A wireless communication system transmits in a High Speed Downlink Packet Access (HSDPA) by having a Radio Network Controller (RNC) assign portions of data to a first serving cell and a second serving cell for transmitting to a user equipment. The first serving cell transmits data on a first downlink carrier to the user equipment. The second serving cell, which is independent from the first serving cell, transmits data on a second downlink carrier to the user equipment. In an optional aspect, the RNC receives a measurement report from the user equipment on a first uplink carrier via at least one of the first serving cell and the second serving cell.

    摘要: Techniques for recovering transmissions on data and control channels with interference cancellation are described. A receiver derives a first interference estimate for a first channel based on a first channel estimate and cancels the first interference estimate from an input signal. The receiver thereafter derives a second interference estimate for the first channel based on a second channel estimate and cancels the second interference estimate in place of the first interference estimate from the input signal. The receiver may derive the first channel estimate based on pilot symbols and may derive the second channel estimate based on a correctly decoded packet. The second channel estimate may be of higher quality than the first channel estimate.

    摘要: User Equipments (UEs) can be adapted to enter into a lower RRC state from a higher RRC state, and search for one or more layers of higher priority within a predetermined period of time upon entering into the lower RRC state. According to at least one aspect, this search for one or more layers of higher priority may be performed irrespective of RF quality of a current serving cell. According to at least another aspect, this search for one or more layers of higher priority may be conducted within the predetermined period of time if a wait period has elapsed since the UE camped on the current serving cell. If the wait period has not elapsed since camping on the current serving cell, the search for one or more layers of higher priority may be performed within the predetermined period of time following a duration of the wait period.
