摘要:
Briefly, in accordance with one or more embodiments, a conventional physical downlink control channel (PDCCH) is transmitted in a first region of a physical downlink control channel structure utilized by a remote radio head that has been assigned a cell identifier that is common to one or more other remote radio heads within the cell, and an enhanced physical downlink control channel (ePDCCH) is transmitted in a second region of the physical downlink control channel structure.

Technology for partitioning small cell physical-layer cell identities (PCI) at a node in a heterogeneous network (HetNet) is disclosed. One method can include the node identifying at least one small cell PCI of a plurality of small cells in a macro cell. Each small cell PCI can be associated with a low power node (LPN) in the HetNet. The node can generate a small cell PCI list to include the at least one small cell PCI. The node can broadcast the small cell PCI list to a wireless device.

Embodiments of the present disclosure describe devices, methods, computer-readable media and systems configurations for management and/or support of multimedia broadcast multicast service (MBMS) service in a wireless communications network. An evolved Node B (eNB) may transmit MBMS assistance information to a user equipment (UE). The MBMS assistance information may identify a carrier by which one or more upcoming MBMS services are to be provided and an indicator of a carrier selection mode to be used by the UE. The UE may transmit an MBMS interest indication message including information related to one or more targeted MBMS services which the UE wants to receive.
摘要:
A variable sub-carrier mapping method comprising steps of: applying different bit interleaving schemes to different transmissions of a hybrid automatic retransmission request (HARQ) process in side of transmitter; and in the side of the transmitter, modulating symbols onto sub-carriers for transmitting. Different transmissions in one HARQ process adopt different bit interleavers or different symbol-to-sub-carrier mapping methods so as to realize that the same bit of different transmissions in one HARQ process is transmitted via different sub-carriers. Therefore, the system achieves the frequency diversity gain and reduces the probability of failure of HARQ transmission caused by that some bits are always transmitted via the sub-carrier with the same deep fading. In this way, the average HARQ retransmission times can be reduced and the system throughput can be improved.

Provided is a method for transitioning between a distributed transmission mode and a localized transmission mode, including transmitting, by a Base Station (BS), a measurement control message to a User Element (UE), wherein the UE makes corresponding measurement and transmits a required measurement report message to the BS and the BS transmits a transition indicator message of new mode to the UE based on measurement report message sent from the UE; and commencing CQI reporting and a downlink transmission of a new mode between the UE and the BS. The BS can choose a more appropriate transmission mode for the downlink transmission based on changing characteristics of the channel in the time domain and the frequency domain.

摘要:
Briefly, in accordance with one or more embodiments, user equipment receives unicast services from a first carrier of a primary serving cell and determines if Multimedia Broadcast and Multicast services (MBMS) services are available on a second carrier based at least in part on information in a broadcast carrier channel that indicates the second carrier or an identification (ID) of the second carrier. If MBMS services are available on the second carrier, the user equipment at least temporarily switches to the second carrier to receive the MBMS services. The user equipment may provide feedback to the network or the primary serving cell when it starts and stops receiving MBMS services, and then may switch back to the primary serving cell when MBMS services have ended or the user equipment no longer desires to receive MBMS services.
摘要:
A method of determining reference signal received power (RSRP) by user equipment (UE) associated with a distributed antenna system (DAS) may include detecting at least three different reference signals in one or more common reference signals (CRSs) that are associated with different antennas in the DAS. The method may also include determining at least three different RSRPs corresponding to the at least three different reference signals. The at least three different RSRPs may be level 3 filtered to produce at least three corresponding filtered powers. The UE may report a maximum of the at least three corresponding filtered powers to the distributed antenna system.

摘要:
A method and apparatus for receiving control information in a mobile communication system. A controller acquires information indicating variable Control Channel Elements (CCEs) allocated for first User Equipments (UEs) among CCEs constituting control channels, acquires information indicating fixed CCEs allocated for second UEs, selects the variable CCEs when a UE receiving the control information is included in the first UEs, and selects the fixed CCEs when the UE is included in the second UEs. A control information receiver receives the control information through the selected CCEs.
