Abstract:
An OFDMA gateway component may serve as an interface between the OFDMA network and CDMA network, detecting a CDMA message targeting the mobile device (610) and, in response, generating an OFDMA message containing information regarding the CDMA message (620, 720). The second aspect is a method comprising: receiving, at an OFDMA base station servicing the mobile device, an OFDMA message containing information regarding a CDMA message sent via a CDMA network targeting the mobile device (620, 720); and - in response, transmitting an OFDMA message containing information regarding the CDMA message form the base station to the mobile device (630, 730). The third aspect is a method comprising: - generating an OFDMA message containing information regarding a CDMA message targeting the CDMA network from the mobile device; and - transmitting the OFDMA message containing the information regarding the CDMA message to an OFDMA base station servicing the mobile device (640, 740, 810).
Abstract:
Methods and apparatus for easily and quickly returning to a first radio access technology (RAT) network when handover to a second RAT network is cancelled are provided. The methods and apparatus may involve a mobile station (MS) entering idle mode before handover to the second RAT network is completed and requesting a serving base station (BS) to retain MS service and operational information, as well as service flow state information. In this manner, should handover to the second RAT network be cancelled before completion, a re-entry to the first RAT network may be expeditiously performed using the retained MS information.
Abstract:
A method for improved decoding of hybrid automatic repeat request (H-ARQ) transmissions may include attempting to verify a physical layer (PHY) cyclic redundancy check (CRC) for a candidate H-ARQ encoder packet. If the PHY CRC is not verified, medium access control layer protocol data units (MPDUs) may be identified in the candidate H-ARQ encoder packet, and attempts may be made to verify a medium access control layer (MAC) CRC for each MPDU in the candidate H-ARQ encoder packet.
Abstract:
Certain embodiments of the present disclosure may allow WiMAX signaling overhead to be reduced by sending burst allocation information to MSs using messages that may be transmitted using more efficient modulation coding schemes (MCSs) than that allowed for DL-MAP and UL-MAP messages. For example, burst allocation information may be sent in SUB-DL-UL-MAP or HARQ-MAP messages that may be encoded with selectable MCSs that result in higher data rate than an MCS used for conventional DL-MAP and UL-MAP messages. For certain embodiments, MSs may be partitioned into groups based on CINR and the burst allocation information for each group may be transmitted using an MCS that is appropriate for that group based on the CINR for MSs in that group.
Abstract:
A system and method for managing wireless communications system resources. The system includes a first mechanism that determines currently available wireless communications system traffic resources and provides a signal in response thereto. A second mechanism de-allocates wireless communications system supplemental resources and reallocates the supplemental resources as traffic resources in response to the signal. In a specific embodiment, the currently available wireless communications system traffic resources include currently available traffic channels, and the supplemental resources include supplemental channels. The first mechanism includes a mechanism that compares a number of in-use traffic channels with a number of total traffic channels and provides the signal when the difference between the number of total traffic channels and the number of in-use traffic channels is less than a predetermined threshold. The first mechanism further includes a mechanism that monitors when a call handoff request and/or a call origination request is blocked at a base station transceiver subsystem call resource manager and provides the signal when the call is blocked. The second mechanism includes a mechanism for sending a message to a selector bank subsystem radio link manager, receiving a response from the selector bank subsystem radio link manager and de-allocating the supplemental resources.

Abstract:
A user equipment (UE) may perform an inter radio access technology (IRAT) measurement in time slots not deemed to be carrying critical data. In such instances, the UE only transmits and decodes critical data in the critical time slots when a serving cell signal is low for a determined period of time. Otherwise, when the time slots do not carry critical data, i.e., non-critical time slots, the UE stops transmitting and decoding and uses the non-critical time slots for IRAT measurement.
Abstract:
A user equipment capable of communicating on multiple radio access technologies (RATs) may receive conflicting paging occasions for each RAT. That is, the paging occasions may occur at sufficiently overlapping times such that a user equipment may not dedicate all its receive resources to each paging occasion. In such instances, a user equipment may divide receive resources among the RATs to receive pages even in the face of paging occasion conflicts.
Abstract:
Wireless communication in a multicarrier radio access network, such as a (TD-SCDMA) network, may be implemented where a user equipment (UE) maintains communication over various carrier frequencies in the multicarrier network. The UE will receive a downlink pilot channel transmitted on every subframe on a primary carrier frequency. The UE will also receive a downlink pilot channel transmitted on less than every subframe on a secondary carrier frequency The downlink pilot channel is sent in subframes on the secondary carrier frequencies using a particular period and offset to reduce or minimize interference.
