    摘要: A method and apparatus for Time Division Duplex (TDD) operation in a wireless transmit/receive unit (WTRU) are disclosed. The method includes receiving a first TDD uplink (UL)/downlink (DL) configuration for a serving cell, receiving a second TDD UL/DL configuration for the serving cell, receiving an indication of directions to use for subframes with conflicting directions between the first TDD UL/DL configuration and the second TDD UL/DL configuration, using the first TDD UL/DL configuration for timing of UL scheduling and UL Hybrid Automatic Repeat Request (HARQ), using the second TDD UL/DL configuration for timing of DL scheduling and DL HARQ, and determining a direction for each subframe with conflicting directions based on the received indication, wherein on a condition that the determined direction for a subframe with conflicting directions is DL, receiving in the subframe in the DL.

    摘要: 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.

    摘要: Embodiments contemplate enhanced physical downlink control channel (EPDCCH). A user equipment (UE) or a wireless transmit/receive unit (WTRU) may receive a first type (e.g., type 1) EPDCCH common search space (CSS) subframe for example is a subset of subframes. The UE or WTRU may monitor first type downlink control information (DCI), for example perhaps within the first type EPDCCH CSS subframe, among other scenarios. A broadcast channel (e.g. MIB) may be received in the first type EPDCCH CSS. The UE or the WTRU may receive configuration information for a second type (e.g., type 2) EPDCCH CSS, for example from the first type EPDCCH CSS. A system information block (SIB) may be received in the second type EPDCCH CSS. The UE or the WTRU may monitor a second type DCI, for example perhaps in the second type EPDCCH CSS.

    摘要: A method and apparatus are described for controlling uplink (UL) transmission power. A wireless transmit/receive unit (WTRU) may receive a configuration of UL subframe sets and maintain a plurality of transmit power control (TPC) command accumulator values that correspond to respective ones of the UL subframe sets. The WTRU may receive a TPC command in a subframe n of a downlink (DL) transmission, determine a subframe n+k of a UL transmission that the received TPC command corresponds to, determine which of the UL subframe sets the UL transmission subframe n+k belongs to, and adjust a TPC command accumulator value that corresponds to the determined UL subframe set to determine power of the UL transmission when transmitting in the UL transmission subframe, where n is an integer, and k is an integer greater than zero.
