Abstract:
Methods and apparatuses are provided for configuring resources at a device operating in a sleep mode of a wireless network. The device can use at least some of the resources for other purposes, such as scanning neighbor base stations, acquiring system parameters of the wireless network or other networks, etc., based in part on requirements of a current interval of the sleep mode. In an available interval, a serving base station may attempt to communicate with the device, and thus, the device can keep at least one receiver chain tuned to the serving base station while assigning other resources to communicate with other base stations. In an unavailable interval, the device can assign all resources for communicating with the other base stations.
Abstract:
A subscriber station may determine whether a service flow between the subscriber station and a base station is retained during an idle mode of the subscriber station. The subscriber station may reactivate the service flow when the subscriber station exits the idle mode. The subscriber station may monitor whether the service flow has data activity. The subscriber station may delete the service flow if there is no data activity.
Abstract:
Methods, systems, and devices are described for utilizing proactive feedback information during a handover of a mobile device from a source base station to a target base station. The mobile device may transmit handover messages to the target base station that includes feedback status information, which may include automatic repeat request (ARQ) information elements in some embodiments. The target base station may request that the source base station transmit packets to the target base station based on the received feedback status information. The source base station may transmit handover messages to the mobile device that include feedback status information in some embodiments. Some embodiments may provide for fast resumption of data transmission by utilizing the proactively sent feedback status information from a mobile device to a base station during handover. Some embodiments may reduce the bandwidth for transferring unnecessary data between base stations.
Abstract:
A method and apparatus for facilitating dynamic time slot allocation is provided. The method may comprise receiving an assignment of at least one of a downlink time slot or an uplink time slot, wherein the downlink time slot is selected based on at least one of a number of used code channels in the downlink time slot, or a downlink transmit power, and wherein the uplink time slot is selected based on at least one of a number of used code channels in the uplink time slot, intra-cell interference, or other-cell interference.
Abstract:
Embodiments of the present disclosure propose a method for addressing MAC protocol data units which include MOB_PAG-ADV messages in an attempt to improve the success rate of decoding BS broadcast paging messages. For example, certain embodiments propose parsing and continuing to decode MPDUs with MOB_PAG-ADV messages although the corresponding CRC failed.
Abstract:
Avoidance of uplink synchronization oscillation in TD-SCDMA systems begins when a user equipment receives a downlink SS command from a Node B. The user equipment obtains a previous uplink timing, which may be from a previous sub-frame associated with the downlink SS command. The user equipment would obtain this previous sub-frame associated with the SS command directly from the Node B as an identification of the Node B's sub-frame delay. The user equipment will then calculate the uplink timing for its next updated uplink signal by combining the previous uplink timing with the synchronization adjustment associated with the SS command. The user equipment then transmits its next uplink signal using the new uplink timing.
Abstract:
A method and apparatus for adjusting and offsetting a power level of uplink transmissions from user equipment in a wireless communication system. In an aspect of the disclosure, a handoff from a source base station to a target base station includes the target base station determining a suitable power offset value and communicating this offset to the source base station. The source base station transmits a handover instruction including the offset to the user equipment (UE), and the UE transmits a synchronization code. The target base station then calculates a further power correction and transmits the correction with an acknowledgment of the synchronization code. The UE then sets the power for future transmissions based in part on the offset and correction values.
Abstract:
In a mobile device for wireless communication capable of communicating on multiple radio access technologies (RATs), cell selection may be improved by reusing cell measurements for inter-RAT cell selection. This will reduce the number of cell measurements taken and improve mobile device performance. A time threshold may be used to instigate new cell measurement to prevent cell measurement data from being outdated.
Abstract:
Transfer of Multimedia Broadcast/Multicast Services (MBMS) over a Single Frequency Network (MBSFN) service and idle mode unicast service for a mobile entity from a source base station to a target base station may be managed by a base station or mobile entity of a cellular wireless communications system (WCS). Operations related to the transfer may include obtaining an MBMS status of the mobile entity, and/or obtaining MBMS support information for the base station. A network entity may facilitate MBMS discovery by a mobile entity, by transmitting a data element to the mobile entity including service identifiers mapped to corresponding cell identifiers to indicate respective MBMS services to be broadcast in an WCS area on adjacent cells identified by respective ones of the cell identifiers. The MBMS services may be broadcast within the WCS area using the adjacent cells previously indicated in the data element.
