    Abstract: PROBLEM TO BE SOLVED: To facilitate efficient cell acquisition in a wireless communication system.SOLUTION: A reference signal for use in cell acquisition can be constructed in a bandwidth-agnostic manner such that it contains a common central portion in a predetermined frequency band that is independent of a bandwidth utilized by an associated wireless communication system. The central portion can be constructed as a two-dimensional block in time and frequency that spans a default cell search bandwidth, a predetermined bandwidth specified by synchronization codes or other signals, or another suitable bandwidth. A reference signal can then be constructed to form the central portion by tiling or expanding the central portion such that it spans the entire system bandwidth.

    Abstract: PROBLEM TO BE SOLVED: To facilitate resource management in a wireless communication system which can enable a network cell in a wireless communication system to mitigate the effects of interference on other surrounding network cells.SOLUTION: A network cell can allocate control resources that overlap control resources of a nearby cell and assign resources within the region of overlap only to users that do not cause substantial interference to the nearby cell. As another example, a network cell can utilize a control channelization that partially coincides with a control channelization and/or a random access channelization of a nearby cell. The network cell can subsequently select not to use the control resources in the coinciding region in order to enable the nearby cell to control the effects of interference in spite of data scheduling.

    Abstract: PROBLEM TO BE SOLVED: To provide a method for facilitating accurate decoding of PDCCH.SOLUTION: Downlink PDCCH is communicated in a manner that mitigates UE from decoding the PDCCH on multiple aggregation levels. Ambiguous payload sizes are identified, and modified through zero padding with one or more bits based on the payload sizes. Aggregation level scrambling sequences can be generated such that the receiving UE can accurately identify the aggregation level on which to decode the PDCCH. Indicator bits that signal the aggregation level to the UE can also be included in the PDCCH.

    Abstract: PROBLEM TO BE SOLVED: To perform channel estimation for wireless communication.SOLUTION: Techniques for deriving channel estimates with different channel estimation filters are described. In one scheme, a filter selection metric is determined for a signal to be recovered, a channel estimation filter is selected based on the filter selection metric, and a channel estimate is derived with the selected channel estimation filter. In another scheme, a first channel estimate is derived with a first channel estimation filter having a first filter response, a first signal is recovered with the first channel estimate, and interference due to the first signal is estimated and removed. A second channel estimate is derived with a second channel estimation filter having a second filter response that is different from the first filter response.

    Abstract: PROBLEM TO BE SOLVED: To provide secondary synchronization encoding by utilizing a primary synchronization channel (P-SCH)-related scrambling code.SOLUTION: Scrambled secondary synchronization codes (SSCs) are assigned to multiple base stations of a radio access network (RAN). By way of example, PSC-based scrambling codes are created from a plurality of M-sequences generated from a common polynomial expression. Further, an SSC codebook is provided that selects sequence pairs of a sequence matrix for generating the SSCs. The selection is based on transmission characteristics of the resulting SSCs, providing reduced interference in planned, semi-planned and/or unplanned mobile deployments.
