摘要： Coverage enhancement of channels in a wireless communication system such as Long Term Evolution (LTE) and LTE-Advanced (LTE-A). Coverage enhancement may include repetition of a channel in the time and/or frequency domain, power boosting of the channel, and reference signal improvement for better channel estimation accuracy. Link adaptation techniques are described, where the link adaptation is dependent on a coverage enhancement (CE) or repetition level. An example method for link adaptation in a Wireless Transmit/Receive Unit (WTRU) in coverage enhancement (CE) mode includes determining the number of repetitions for an uplink channel, deriving the transmission power for the uplink channel based on the number of repetitions, and transmitting the channel with the determined number of repetitions at the transmission power level. Link adaptation based on CE level or repetition level is described for uplink and downlink channels including data, control, access, and broadcast channels.

摘要： Systems, methods, and instrumentalities are disclosed to describe cell selection in low cost machine type communication (LC-MTC) devices. An LTC-MC device may measure a plurality of downlink signals from a plurality of cells. The LTC-MC may detect a channel condition, e.g., by determining a cell with better uplink coverage than a downlink cell. The detection of the channel condition may include measuring an uplink pathloss. The LTC-MC may report the channel condition as a decoupled channel condition, e.g., when an uplink cell is identified with uplink coverage better than the downlink cell. The channel condition may be reported, e.g., via a set of Physical Random Access Channel (PRACH) preambles. The set of PRACH preambles may be predefined. The channel condition may be reported via a higher layer signaling.

摘要： 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.

摘要： Managing a handover (e.g. over a Un or Uu connection or interface) of a mobile (moving) relay, MRN, from an eNB (source eNB) to another eNB (target eNB). The source eNB or donor eNB (DeNB) may provide a backhaul link to the mobile relay, MRN, and the MRN may provide an access link to a user equipment (UE). To manage the handover, access information (e.g. Donor eNB, DeNB, cell list) may be received (from an operation and maintenance entity, OAM), and a determina¬ tion may be made regarding whether one or more target eNBs may be capable of handling the relay based on the access information (i.e. whether it is relay capable, relay accessible, supports relays or not). A target eNB, that may be capable of handing the relay based on the determination, may be selected from the one or more target eNBs to handover the relay to where the selected target eNB may have a communication (backhaul) link with the source eNB. The relay may be handed over from the source eNB to the selected target eNB using the communication link between the source eNB and selected target eNB. The relay may be configured to use radio access network (RAN) shar¬ ing, a mobility management entity (MME) may be selected; and/or a EUTRAN radio access bearer (E-RAB) may be modified.

摘要： Embodiments described herein may include methods, systems, and apparatuses that support transmissions in wireless transmit and receive units (WTRUs) having reduced capabilities. Uplink transmissions and multimedia broadcast multicast service (MBMS) may be supported in WTRUs operating on a reduced bandwidth within an overall system bandwidth by receiving an uplink (UL) resource allocation within the reduced bandwidth, and sending a transmission over the UL resource allocation. The reduced bandwidth may include a small number of physical resource blocks (PRBs) that do not overlap with PRBs located on the band edge of the overall system bandwidth containing a system PUCCH. The UL resource may be located in both band edges of the reduced bandwidth, may be a PRB-pair in the same frequency of the reduced bandwidth, or may be a PRB-pair in a first slot in a first subframe and second slot in a second subframe of the reduced bandwidth.

摘要： 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.

摘要： An authentication assurance level associated with an entity, for instance a user equipment, may be computed periodically or in response to an event. The authentication assurance level is compared to an authentication threshold. Based on the comparison, it is determined whether a fresh performance of at least one authentication factor needs to be performed. Thus, appropriate authentication factors and functions may be invoked on a periodic basis to maintain a certain authentication assurance level, which is referred to herein as the assurance threshold. The authentication assurance level may change, for instance decay, over time and may be refreshed periodically.
