摘要:
User equipments (UEs) will monitor each frequency in a multicarrier wireless radio access network for at least one control channel that may contain downlink data allocations or other such messages from the network. This monitoring may be dynamically controlled with a physical layer indication received by the UE from a node B that designates a number of carrier frequencies of all of the carrier frequencies of the network. In response to this physical layer indication, the UE will monitor at least one control channel in the designated carrier frequency or frequencies.

Certain aspects of the present disclosure propose techniques for service redirection in Time Division Synchronous Code Division Multiple Access (TD-SCDMA) and Global System for Mobile communications (GSM) hybrid mobile terminals.
摘要:
Certain embodiments of the present disclosure provide a method for communicating, by a multi-mode mobile station (MS), with first and second networks via first and second radio access technologies (RATs). The method generally includes determining a first set of one or more paging parameters in an effort to establish a listening interval of a sleep cycle of the first network that aligns with a sleep interval of a control channel cycle of the second network and communicating the first set of paging parameters to a base station of the first network in a request to establish the sleep cycle of the first network.
摘要:
A base station may be configured so that it operates in accordance with certain MAP transmission rules that may enable mobile stations to save battery power in certain situations. Upon receiving a MAP message, a mobile station may determine whether there is a burst allocated for the mobile station in the current frame by determining the value of at least one of the following: an idle users bit in the SUB-MAP pointer information element (IE), and a sleep users bit in the SUB-MAP pointer IE. The mobile station may discontinue processing of the MAP message and power down one or more components of the mobile station if there is not a burst allocated for the mobile station in the current frame.

Certain embodiments of the present disclosure provide a method for communicating by a multi-mode mobile station (MS) with first and second networks via first and second radio access technologies (RATs). The method generally includes measuring a time offset between frames of the first RAT and frames of the second RAT while maintaining a connection with the first network via the first RAT, sending a request to a base station of the first network to establish scan periods during which the MS may switch to the second network to monitor for paging messages, and switching to the second network to monitor for paging messages during a scan period without terminating the connection with the first network. The first RAT may comprise, for example, WiMAX, while the second RAT may comprise, for example, CDMA.

A method for subscriber station-based admission control may include determining that there is demand for a new connection at the subscriber station. The method may also include determining whether the new connection should be admitted based on resource availability. The method may also include sending a request for the new connection to a base station if it is determined that the new connection should be admitted.
摘要:
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.
摘要:
A method for intra-user quality of service (QoS) uplink scheduling may include determining scheduling types associated with active uplink connections that are maintained by the subscriber station. The method may also include determining QoS parameters corresponding to the different scheduling types. The method may also include scheduling the active uplink connections for uplink transmissions based on the different scheduling types and their corresponding QoS parameters.
摘要:
A user equipment may save power by reducing certain battery draining activities when the battery power remaining in the UE fails to meet a threshold value. The UE may skip inter-radio access technology measurements to conserve battery life when the battery power in the UE fails to meet the threshold. The UE may also extend inter-radio access technology measurement periodicity when the battery power in the UE fails to meet the threshold.
摘要:
Certain aspects of the present disclosure present methods and apparatus for selecting a power saving mode for a mobile station (MS) in a wireless network. The power saving mode may be selected based on the traffic that is observed at the MS in a predefined duration. Once low overall data traffic is observed, the device may enter a first low power state. If data traffic of a particular type (e.g., not for management or maintenance purposes) is not observed for a predetermined duration, the device may enter a second low power state (deeper than the first low power state).
