摘要:
Techniques for determining a discontinuous reception (DRX) cycle used to receive paging are described. A user equipment (UE) may have (i) a first DRX cycle used by a first network (e.g., a core network) to page the UE and (ii) a second DRX cycle used by a second network (e.g., a RAN) to page the UE. In an aspect, the UE may use the longer DRX cycle and ignore the shorter DRX cycle, when allowed, to extend battery life. In one design, the UE may receive an indication of whether the second DRX cycle can be ignored or is to be considered by the UE. The UE may use the longer DRX cycle if the second DRX cycle can be ignored and may receive paging from the first network and/or the second network based on the longer DRX cycle. In another aspect, the UE may negotiate a DRX cycle with a network.

Certain aspects of the present disclosure provide a method for bearer count alignment during handover of a user equipment (UE) from a first radio access technology (RAT) to a second RAT. The UE establishes radio resource control (RRC) connections with the second RAT and transmits data radio bearer (DRB) capability of the UE to the second network. The second network utilizes this information to set up the DRBs with the UE.
摘要:
A method for a wireless communication system includes broadcasting that a first service is available in a first MBSFN and a second service is available in a second MBSFN. The method includes supporting a service not broadcasted as available. For example, supporting the first service with the second MBSFN and/or supporting the second service with the first MBSFN. The supporting or reinforcing can be done by echoing. The echoing is scheduled along with the owned service.
摘要:
Systems and methodologies are described that facilitate improved management of a system information modification in a wireless communication environment. Various techniques can be utilized as described herein to provide respective users with information indicative of changes to specific blocks or elements within a set of system information, thereby simplifying and accelerating acquisition of new system information after a modification. In a first example, a bitmap is generated and transmitted upon a system information modification that indicates which blocks(s) and/or element(s) of the system information changed in the modification, thereby allowing an associated user to abstain from reading or processing unchanged system information. In a second example, respective block(s) and/or element(s) of the system information can include an internal value tag that indicates to a receiving entity whether the corresponding block(s) or element(s) have changed, thereby allowing a user to discard unchanged block(s) or element(s) without performing further processing.

Systems and methodologies are described that facilitate classification and identification of a channel associated with a wireless data transmission. As described herein, a channel designated for transmission of a packet can be selected from among multiple usable channels, based on which a bit at a predefined location in the packet can be set to a logical value indicative of the selected channel. As further described herein, extraction of the logical value from the predefined location and identification of the corresponding channel can be performed by a recipient of the packet without requiring parsing of the message. In one example described herein, a Dedicated Control Channel (DCCH) can be identified by setting a Logical Channel Identifier (LCID) bit in a DCCH packet to a predefined value. In another example, a Common Control Channel (CCCH) can be identified by embedding a Boolean constant within a message structure contained in a CCCH packet.
摘要:
The method and apparatus as described are directed toward techniques and mechanisms to improve efficiency in wireless communication networks through optimization of handover scenarios. Determining whether an intra-base station or inter-node-B handover is too performed, and determining the protocol layers to reset during the handover based at least in part on the type of handover to be performed increases the overall efficiency of the wireless network.

Techniques for performing positioning in a cellular network are described. In one design, a first base station (e.g., a home base station) determines its position based on position information for at least one user equipment (UE) within radio coverage of the first base station and a second base station. The first base station sends at least one position request for the at least one UE to the second base station, receives position information for the at least one UE from the second base station, and determines a position estimate for itself based on the position information. In another design, the second base station receives a position request for the first base station, obtains position information for at least one UE, determines a position estimate for the first base station based on the position information, and sends the position estimate to the first base station.
摘要:
Techniques to support operation in a compressed mode and/or a continuous packet connectivity (CPC) mode are described. In an aspect, a user equipment (UE) may obtain an assignment of enabled subframes for the CPC mode and an assignment of transmission gaps for the compressed mode. The transmission gaps may be aligned with idle times between the enabled subframes. The UE may exchange data during enabled subframes not overlapping the transmission gaps and may skip data exchanges during enabled subframes overlapping the transmission gaps. The UE may make cell measurements during the transmission gaps. In another aspect, the UE may obtain enabled subframes and skipped subframes, exchange data during enabled subframes not corresponding to the skipped subframes, and skip data exchanges during the skipped subframes. In yet another aspect, the UE may receive orders on a shared control channel to quickly enable and disable the compressed mode.

In accordance with aspects of the disclosure, a method, apparatus, and computer program product are provided for wireless communication. The method, apparatus, and computer program product may be configured to provide a message from a first network to a device, wherein the message comprises one or more parameters for access to a second network, direct the device to switch from the first network to the second network based on the one or more parameters provided by the first network, and direct the device to perform random access on the second network based at least in part on the one or more parameters provided by the first network. The one or more parameters may comprise a priority parameter for performing random access on the second network.
