摘要： Systems and methodologies are described that facilitate implementing a linear adaptive equalizer receiver on the downlink link of a UMTS TDD wireless communication system. A reference signal can be generated based on multiple non-common midamble sequences in a time slot of a received transmission. Traffic-to-pilot ratios for channel codes in the time slot can be generated, and relative strengths of channel codes associated with specific midambles can be determined to weight the midamble. A plurality of the weighted midambles can then be utilized to generate a reference signal to train the equalizer, which can facilitate utilization of total aggregate midamble energy rather than midamble energy associated with a single midamble in the signal.

摘要： Systems and methodologies are described that facilitate supporting uplink soft handoff in a UMTS TDD wireless communication environment. A virtual active set (VAS) for each user device can be generated at the network side of the communication environment, and sectors listed in each VAS can be informed of their respective listings. Sectors in a user device's VAS can be provided with a scrambling code and resource assignments from a nominal sector serving the user device, which information can be employed to attempt to receive and demodulate uplink signals from the user device at all base stations in the VAS thereof. Additionally, such resources can be employed to transmit power control and reverse activity commands to the user device on the downlink.

摘要： Systems and methodologies are described that facilitate increasing system capacity in a code-limited WCDMA (e.g., TDD, FDD, . . . ) wireless communication environment. According to one aspect, a larger code space can be defined by introducing multiple code clusters within a sector, wherein each cluster has a unique scrambling code. Codes within a cluster can have orthogonal Walsh sequences that can be assigned to user devices to facilitate communicating over a wireless network and can overlap with codes in another cluster. The unique scrambling code assigned to each cluster can ensure that duplicate Walsh sequences in another cluster in the same sector appear as a pseudo-noise codes.

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： Systems and methodologies are described that facilitate defining new control channels in legacy wireless networks. Control data resources for new systems can be defined over resources reserved for general data communications in the legacy wireless network specification. In this regard, legacy devices can still be supported by devices implementing new control data resources, and the new control data resources can avoid substantial interference that is typically exhibited over legacy control and/or reference signal resources by instead using the general data resources. In addition, new system devices can avoid scheduling data communication resources over the new control resources to create a substantially non-interfered global control segment. Control data can be transmitted over the segment using beacon-based technologies, reuse schemes, and/or the like.

摘要： Systems and methodologies are described that facilitate performing fast cell selection in a user device wherein the user device can select a serving sector from a list of sectors in its virtual active set (VAS), while in communication with a wireless network. The serving sector can be different from a nominal sector whose scrambling code the user device employs for transmission on the uplink, which scrambling code can be known to all sectors listed in the VAS for the user device. In this manner, all sectors in whose coverage area the user device is located can be included in the user device's VAS and can receive and demodulate transmissions there from.
