Abstract:
Methods and apparatuses are provided that include decoding multicast broadcast communications where scheduling information related to a multicast channel is not properly received over a control channel. Media access control (MAC) packets can be decoded to determine whether a MAC subheader indicates the packet relates to a logical channel by indicating an associated channel identifier. Where the channel identifier of the MAC packet matches that of a requested logical channel, data in the MAC packet can be provided to a communications layer. Subsequent packets can be processed and provided to the communications layer until a different channel identifier is encountered.
Abstract:
This disclosure provides methods and systems for translating quality of service (QoS) parameters of a first radio access technology (RAT), e.g., Worldwide Interoperability for Microwave Access (WiMAX), to QoS parameters of a second RAT, e.g., code division multiple access (CDMA) high rate packet data (HRPD). The methods and systems facilitate a handover by a multi-mode mobile station or other wireless device from the first RAT to the second RAT and vice versa.
Abstract:
Wireless communication in a radio access network may be implemented where a user equipment (UE) sends a hold signal to a Node B indicating that data transmission to the UE is to be put on hold. The UE may resume data transmission from the Node B by sending a resume signal to the Node B. During the hold in transmission, the UE may measure a GSM network to assist in handover of the UE between a TD-SCDMA network and a GSM network.
Abstract:
Wireless communication in a multicarrier radio access network may be implemented where a user equipment (UE) maintains communication with various carrier frequencies in the multicarrier network. The UE will receive an indication from a node B to measure a signal quality on one of a number of carrier frequencies in the network. The UE will then measure the signal quality on the carrier frequency based on measurements using a downlink synchronization code transmitted by the node B on the downlink pilot channel of the carrier frequencies in the multicarrier network. The UE may then report the channel quality back to the node B.
Abstract:
A method and apparatus for allowing a dual-mode mobile device to communicate with a CDMA network without switching from an OFDMA network are provided. For certain embodiments, an OFDMA gateway component may serve as an interface between the OFDMA network and CDMA network, detecting a CDMA message targeting the mobile device and, in response, generating an OFDMA message containing information regarding the CDMA message.
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:
Certain aspects of the present disclosure propose techniques for performing a time division duplex-long term evolution (TDD-LTE) measurement in a time division synchronous code division multiple access (TD-SCDMA) system. Certain aspects provide a method that generally includes obtaining measurements of downlink (DL) transmission from a base station (BS) of a second radio access technology (RAT), maintaining uplink (UL) transmission with a BS of a first RAT while obtaining the measurements, and performing network acquisition operations with the BS of the second RAT based on the measurements.
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.
Abstract:
Certain aspects of the present disclosure provide methods and apparatus that may help alleviate load conditions by taking action to select one or more mobile stations (MSs) for handover to a neighbor base station are provided.
Abstract:
Certain aspects of the present disclosure propose techniques for utilizing synchronization shift (SS) bits in Time Division Synchronous Code Division Multiple Access (TD-SCDMA) based uplink communications. The SS bits can be used for various purposes different from indicating timing of transmissions from a Node B to a user equipment.
