摘要： A user equipment in a wireless communications system supporting direct communication between user equipments selects a sidelink destination group (ProSe destination) associated with a sidelink logical channel having a highest logical channel priority among sidelink logical channels, which have data available for transmission in a sidelink control period (SC period) and which have not previously been selected in the same SC period, wherein each of the sidelink logical channels belongs to a sidelink destination group, each of the sidelink logical channels is allocated to a logical channel group (LCG) depending on a priority of said each sidelink logical channel and on a priority of the logical channel group, and the logical channel group is defined per sidelink destination group. The user equipment allocates radio resources to sidelink logical channels belonging to the selected sidelink destination group in decreasing priority order, and transmits the data using the allocated radio resources.

摘要： Control information may be transmitted for different TTI lengths. Different control information for the different TTIs may be transmitted using control channel resources that are established for communication of control information, such as a physical downlink control channel (PDCCH), for example. Control information for a first TTI may be located in a first set of resources, and control information for a second TTI may be located in a second set of resources. The first set of resources may be located within a first search space that may be searched by a user equipment (UE) to identify the first control information. The second set of resources may be located within a second search space that may be searched by the UE to identify the second control information.

摘要： In a wireless communication base station device, a modulation unit carries out modulation processing for Dch data after coding to generate a Dch data symbol. A modulation unit carries out modulation processing for Lch data after coding to generate an Lch data symbol. An allocation unit allocates the Dch data symbol and Lch data symbol to each sub-carrier composing an OFDM symbol and outputs the allocated sub-carrier to a multiplex unit. In this case, the allocation unit allocates the Dch data symbol to a plurality of resource blocks where one Dch is arranged at an interval equal to integral multiples of the number of resource blocks composing a resource block group.

摘要： A system and method for providing both localized and distributed transmission modes for EPDCCH is disclosed, where one EPDCCH comprises of one or multiple CCEs. Localized versus distributed transmission may be defined in terms of the EPDCCH to CCE resource mapping. In a localized transmission CCEs are restricted to be contained within one PRB. In a distributed transmission a CCE spans over multiple PRBs. A UE can be configured to either receive the EPDCCH only in localized or only in distributed transmissions. A UE can also be configured to expect EPDCCH transmissions in both localized and distributed transmissions. In each PRB configured by the higher layer as an EPDCCH resource, 24 REs that may be used for any DMRS transmission are always reserved and not used for EPDCCH transmission.

摘要： This invention relates to a proposal of an uplink resource assignment format and a downlink resource assignment format. Furthermore, the invention relates to the use of the new uplink/downlink resource assignments in methods for (de)activation of downlink component carrier(s) configured for a mobile terminal, a base station and a mobile terminal. To enable efficient and robust (de)activation of component carriers, while minimizing the signaling overhead, the invention proposes a new uplink/downlink resource assignment format that allow the activation/deactivation of individual downlink component carriers configured for a mobile. The new uplink or downlink resource assignment comprises an indication of the activation state of the configured downlink component carriers, i.e., indicate which downlink component carrier(s) is/are to be activated or deactivated. This indication is for example implemented by means of a bit-mask that indicates which of the configured uplink component carriers are to be activated respectively deactivated.

摘要： Systems, methods, and devices are disclosed for determining a beam modulation mode and/or a carrier modulation mode. A beamformed reference signal may be transmitted to a wireless transmit/receive unit (WTRU). A beam measurement report may be received from the WTRU. The beam measurement report may include a beam modulation mode recommendation and/or a carrier modulation mode recommendation. A beam modulation mode and/or a carrier modulation mode may be determined based on a mode recommendation. A beam modulation mode and/or a carrier modulation mode may indicate a manner of transmitting same information on multiple beams.

摘要： A method for transmitting a physical uplink shared channel (PUSCH) is discussed. The method is performed by a wireless device and includes receiving downlink control information (DCI), which is repeated on a plurality of downlink subframes, identifying a last subframe on which the repetition is completed, determining that the identified last subframe is not used for determining a start subframe to repeatedly transmit the PUSCH, substituting the last subframe with a first subframe usable for determining the start subframe to transmit the PUSCH after the identified last subframe, based on the determination that the identified last subframe is not used for determining the start subframe; determining the start subframe to transmit the PUSCH, based on the first subframe other than the last subframe, and transmitting the PUSCH repeated over a plurality of subframes starting from the determined start subframe.
