An interference measurement resource (imr) allocation method and apparatus for allocating resources for efficient interference measurement in a downlink in a system supporting a new carrier type (nct) is provided. The interference measurement configuration method of a base station transmitting subframes including, or not including, cell-specific reference signals (crs) in a wireless communication system includes determining whether a terminal supports a new carrier type (nct) subframe, allocating, when the terminal supports the nct subframe, interference measurement resources (imr) to the terminal at resource elements (res) where other signals are not mapped in the subframe, transmitting information on the allocated imr to the terminal, and transmitting the subframe including the allocated imr to the terminal..
| Method for reporting downlink channel state and apparatus therefor|
A method for reporting a channel state to a base station (bs) supporting downlink (dl) multiple-input multiple-output (mimo) in a wireless communication system includes measuring a dl channel based on a dl signal received from the bs, and reporting an index of a codebook for precoding of the dl signal according to the measured dl channel, wherein the codebook for precoding includes an integrated codebook having a dual structure including a codebook for a wideband and a codebook for a subband, and wherein the integrated codebook is determined depending on an index i1 of the codebook for the wideband and an index i2 of the codebook for the subband, and a structure or type of a codebook selectable using the index i2 varies according to the index i1.. .
| Aggregation of carriers of a cellular radio network with carriers of an auxiliary network|
A method and devices for integrating a cellular radio network with a wifi network are disclosed. According to one aspect, a method includes selecting, at a base station having a cellular radio subsystem and a wifi radio subsystem, at least one of a cellular radio network carrier and a wifi carrier to carry at least one data flow from the base station to a user equipment.
| Generating short term base station utilization estimates for wireless networks|
Monitoring within a network a history of bits throughput to a base station over each of a plurality of time intervals, monitoring within the network a physical resource block utilization level over each of the plurality of time intervals, determining a ratio of the history of bits to the utilization level for each of the plurality of time intervals, determining an updated history of bits for each of a plurality of upcoming time intervals, estimating an updated utilization level in response to the updated history of bits and the ratio, generating messaging to at least one additional network element conveying the estimated updated physical resource block utilization level, and adjusting at least one of a prefilling process or a prefetching process in response to the updated utilization level.. .
| Early termination of a base station identity code procedure in td-sdcma|
An early bsic (base station identity code) abort procedure includes comparing a first signal strength of a serving cell with a first threshold and comparing a second signal strength of a target cell to a second threshold. The first threshold is a sum of a network indicated threshold and a user equipment (ue) threshold.
