摘要： Techniques for estimating thermal noise and rise-over-thermal (RoT) in a communication system are described. In an aspect, thermal noise in a sideband may be measured and used to estimate thermal noise in a signal band. In one design, received power in the sideband may be measured, e.g., by computing total power of FFT transform coefficients within the sideband. Thermal noise may be estimated based on (e.g., by filtering) the measured received power in the sideband. Received power in the signal band may also be measured. Total received power may be estimated based on (e.g., by filtering) the measured received power in the signal band. RoT may then be estimated based on the estimated thermal noise and the estimated total received power. The estimated RoT may be used to estimate an available load for a cell, which may be used to admit and/or schedule users in the cell.

摘要： Techniques for scheduling users for transmission on the uplink in a wireless communication system are described. In one design, a total load for a cell may be determined based on a rise-over-thermal (RoT) measurement. An in-cell load for users served by the cell may be determined based on uplink transmissions received from these users. An outside load due to users in neighbor cells may be determined based on the total load and the in-cell load. A target total load for the cell may be determined based on a target RoT for the cell. An available load for the cell may be determined based on the target total load for the cell and the outside load. Users in the cell may be scheduled for transmission on the uplink based on the available load for the cell.

摘要： In aspects of the present disclosure, a user equipment receives inter-NodeB multi-point transmissions, and a multipoint aggregation component detects a gap in the sequence numbers, delays transmitting a not acknowledged signal (NAK) by starting a NAK delay timer, and transmits, by a transceiver, NAK for the gap in sequence numbers in response to the NAK delay timer expiring and detecting that the gap has not been filled during the delaying. If the Medium Access Control (MAC) entity as the respective NodeB identifies itself to the Radio Link Control (RLC), out-of-order delivery (skew) can eventually be distinguished from genuine data loss before the NAK delay timer expires based upon tracking the highest sequence numbers received. Adaptive NAK delay timer can be performed by monitoring skew duration.

摘要： The present disclosure provides methods and apparatuses for improved Iub link congestion management based on a dynamic scaling of flow control request message transmission in multiflow wireless environments. For example, in an aspect, methods and apparatuses are provided for receiving, at a NodeB, a data request from one or more user equipment (UE), wherein each data request corresponds to a flow and the one or more UE is served by a plurality of NodeBs, generating a flow control request corresponding to each flow in response to each data request, and sending each flow control request to a radio network controller (RNC). Thereafter, a Node B may receive data in response to each flow control request, determine a congestion state based on a downlink delay from the RNC detected in the received data, and scale a subsequent one or more flow control requests based on the determined congestion state.

摘要： Systems, methods, devices, and computer program products are described for discontinuous multi-carrier uplink management in a wireless communication system. Common timing parameters may be identified for use in relation to discontinuous uplink transmissions on each of a two or more wireless carriers concurrently transmitting from an access terminal. A first operational state is associated with a first wireless carrier, while a second, different state is associated with a second wireless carrier. The first carrier may be operated in the first operational state concurrently with the second carrier being operated in the second operational state, with each carrier operated in accordance with the common timing parameters.

摘要： A method and apparatus for wireless communication may provide an RLC reset procedure tailored for a multipoint HSDPA system utilizing a plurality of disparate Node Bs to provide an RLC flow from an RNC to a UE. Some aspects of the disclosure provide for a flush request to be provided to each of a plurality of Node Bs utilized as serving cells in the multipoint HSDPA system, so that stale packets are not retained in internal buffers at the Node Bs following the RLC reset procedure. In some examples, the RLC reset procedure is only completed after confirmation that the flush of the internal buffers has been completed. Confirmation may be explicitly provided by each Node B utilizing a backhaul interface, or may be implicitly determined utilizing timers or signaling between the respective Node Bs.

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.
