摘要： A method and apparatus for sending uplink control information by a multi-mode wireless transmit/receive unit (WTRU) capable of operating on multiple component carriers of a plurality of radio access technologies (RATs) for multi-RAT operation are disclosed. The WTRU may generate uplink control information (UCI) pertaining to a first RAT and a second RAT, wherein the UCI may include a first plurality of hybrid automatic repeat request acknowledgements (HARQ-ACKs) pertaining to a plurality of downlink (DL) transmissions of the first RAT and a second plurality of HARQ-ACKs pertaining to a plurality of DL transmissions of the second RAT. The WTRU may multiplex at least part of the generated UCI pertaining to the first RAT and at least part of the generated UCI pertaining to the second RAT onto a physical channel on a component carrier of the second RAT.

摘要： Methods and apparatus for performing device-to-device (D2D) discovery are described. A service discovery process may include a discoverable device (e.g., a wireless transmit/receive unit (WTRU)) sending a discovery request, over a wireless connection, for a radio resource for the purpose of performing a transmission for radio frequency (RF) proximity detection for a given service. The WTRU may receive a discovery response including a configuration for RF proximity detection from a network, which configuration may be associated to the service. The configuration for RF proximity may be received by dedicated signaling, (e.g., physical downlink shared channel (PDSCH)), in particular for a discoverable WTRU. The configuration for RF proximity may be received on a broadcast channel, (e.g., a discovery shared channel (DISCH)), in particular for a monitoring WTRU, and may include one or more service identities, each associated with an RF proximity detection configuration, or a validity information and a measurement configuration.

摘要： Methods and apparatuses are provided for generating a protocol data unit (PDU). An apparatus may comprise a processor configured to provide a medium access control (MAC) entity and a segmentation entity. The MAC entity may indicate an amount of data associated with the segmentation entity to be multiplexed by the MAC entity. The segmentation entity may segment, based on the indicated amount of data, a service data unit (SDU) into a segment, and the MAC entity may multiplex the segment into a MAC protocol data unit (PDU). The MAC PDU may include a field that indicates whether the segment is included and whether the segment is a last segment. The apparatus may further comprise a transmitter configured to transmit the MAC PDU.

摘要： Systems, methods, and instrumentalities are disclosed to manage interference caused by D2D communications. A wireless transmit receive unit (WTRU) may include a processor. The processor may be configured to perform one or more of the following. The processor may determine to send information using a device-to-device transmission via a resource pool from a plurality of resource pools. Each resource pool may be associated with a range of reference signal receive power (RSRP) values. The processor may determine a RSRP measurement of a cell associated with the WTRU. The processor may select a resource pool from the plurality of resource pools based on the RSRP measurement of the cell. The RSRP measurement of the cell may be within the range of RSRP values associated with the selected resource pool. The processor may send the information using the selected resource pool.

摘要： Methods and devices for offloading and/or aggregation of resources to coordinate uplink transmissions when interacting with different schedulers are disclosed herein. A method in a WTRU includes functionality for coordinating with a different scheduler for each eNB associated with the WTRU's configuration. Disclosed methods include autonomous WTRU grand selection and power scaling, and dynamic prioritization of transmission and power scaling priority.

摘要： A wireless transmit/receive unit (WTRU) may utilize pre-configured rules for scaling power levels. Channels may be grouped based on a type of data to be transmitted. A power level of a channel from a group may be scaled using the pre-configured rules. A power level of a channel of a supplementary carrier may be scaled before another channel of a non-supplementary carrier.

摘要： A method and apparatus are described. A method includes determining whether the apparatus is in a coverage enhancement (CE) mode or a non-CE mode. The method further includes receiving a CE-system information block (CE-SIB) on a physical downlink shared channel (PDSCH) based on at least one of a known location or at least one known parameter for the CE-SIB, on a condition that the WTRU is determined to be in the CE mode.

摘要： Embodiments contemplate methods and systems for determining and communicating channel state information (CSI) for one or more transmission points (or CSI reference signal resources). Embodiments further contemplate determining transmission states may include applying at least one CSI process for channel state information (CSI) reporting. Embodiments also contemplate aperiodic and/or periodic reporting of one or more report types (e.g., rank indicator (RI)) of CSI, perhaps based on one or more reporting modes that may be configured for each of the one or more CSI process.

摘要： Methods and systems are disclosed for providing physical layer resources to a plurality of medium access control (MAC) instances that are associated with different serving sites that are independently scheduled. For example, a WTRU may utilize a first physical layer configuration for transmitting to a first serving site associated with a first MAC instance. The WTRU may utilize a second physical layer configuration for transmitting to a second serving site associated with a second MAC instance. The WTRU may prevent conflicts between transmission requests from the first MAC instance and transmission requests from the second MAC instance. For example, preventing the conflicts may include utilizing one or more of time segregation or frequency segregation for transmissions associated with the first MAC instance and transmissions associated with the second MAC instance.
