  • Publication number: 20150036645
    Abstract: Systems, methods, and instrumentalities are disclosed for downlink resource allocation associated with a shared frequency band. A WTRU may receive resource allocation information associated with a component carrier and at least one carrier segment. The component carrier and the least one carrier segment may each comprise a plurality of resource block groups (RBG). At least two bitmaps may be associated with the resource allocation information. A size of a resource block group (RBG) of the component carrier and the at least one carrier segment may be based on a combined number of resource blocks (RB) of the component carrier and the one or more carrier segments divided by a 3GPP Rel-8/Rel-10 RBG size of the component carrier. The WTRU may determine at least one RBG allocated to the WTRU using the resource allocation information and may receive and decode the at least one RBG allocated to the WTRU.

  • Publication number: 20150024706
    Abstract: A personal wireless device is utilized to carry out measurements of one or more network-performance related metrics in response to a triggering event. The triggering event can be a message that is transmitted by a network element to the personal wireless device. The personal wireless device may be exemplified by a variety of personal devices such as, for example, a cellular phone, or a personal digital assistant (PDA). The measurements may be used to derive network-performance related information such as cellular signal coverage areas, signal hole areas, and signal interference areas.

  • Publication number: 20140219159
    Abstract: A method and apparatus are described for providing multimedia broadcast multicast services (MBMS) service feedback. A wireless transmit/receive unit (WTRU) may receive an MBMS service query message over an MBMS control channel and transmit an MBMS service response. The MBMS service query message and MBMS service response message may be radio resource controller messages. The MBMS service query message may include MBMS service identifiers which identify MBMS services that the WTRU is receiving or intending to receive. The WTRU may generate a report with MBMS service identifier index values, where each MBMS service identifier index value indicates a position of a service identifier corresponding to an MBMS service in the original query list that the WTRU is currently receiving or intending to receive. The MBMS service status query message may be received alone or along with a MBSFNAreaConfiguration message. The WTRU may respond within a predetermined or configured time limit.

  • Publication number: 20140098761
    Abstract: A method and apparatus are described for a low cost machine-type-communication (LC-MTC) wireless transmit/receive unit (WTRU) to enhance coverage. An example method for physical broadcast channel (PBCH) enhancement includes receiving system information on an enhanced PBCH (ePBCH). The ePBCH is located in a set of radio frames which is a subset of available radio frames, where the subset includes fewer than all the available radio frames. The ePBCH is received in at least one radio frame of the set of radio frames. An example method for physical random access channel (PRACH) enhancement includes receiving configuration of legacy PRACH resources and enhanced PRACH (ePRACH) resources. The WTRU selects one of legacy PRACH resources or ePRACH resources based on a coverage capability. Another example method for PRACH enhancement includes receiving configuration of ePRACH resources. The ePRACH resources include multiple ePRACH resource types, each ePRACH resource type being associated with a coverage capability.

  • Publication number: 20130183971
    Abstract: Systems or methods for managing a handover (e.g. over a Un or Uu connection or interface) of a relay from an eNB such as a source eNB to another eNB such as a target eNB may be provided where the source eNB or DeNB may provide a backhaul link to the relay and the relay may provide an access link to a user equipment (UE). To manage the handover, access information may be received and a determination may be made regarding whether one or more target eNBs may be capable of handling the relay based on the access information. Additionally, the relay that may be handed over may be configured to use radio access network (RAN) sharing, a mobility management entity (MME) may be selected, and/or a EUTRAN radio access bearer (E-RAB) may be modified.

  • Publication number: 20130114472
    Abstract: Embodiments contemplate enabling relay node uplink control information transmission on an interface between a relay node and a donor eNodeB (DeNB) in one or more subframes. Embodiments contemplate techniques to avoid restrictions on uplink transmissions on a cell (perhaps due to subframe configuration), such as on a primary cell, where the restrictions may make relay node uplink control information transmission difficult (if not impossible) on the interface between a relay node and a donor eNodeB (DeNB). Embodiments also contemplate that resources on the interface between the relay node and the donor eNodeB may be scheduled across one or more component carriers or serving cells.
