To support the transmission of downlink and uplink transport channels Downlink Shared Channel(DL-SCH) and Uplink Shared Channel (UL-SCH) control signaling is required.

Subsets of those groups can be paged with reduced decoding requirements.Air Messenger ASCII v.8.0.5 Air Messenger ASCII gives you the ability to interface multiple software applications or device for paging by generating a simple text file that our software can process into a page. The Downlink Control Information (DCI) is transmitted through the Physical Downlink Control Channel (PDCCH) and includes information about the DL-SCH resource allocation (the set of resource blocks containing the DL-SCH), transport format and information related to the DL-SCH Hybrid Automatic Repeat reQuest (ARQ).Systems and methods for utilizing paging group IDs and paging indicators are.Multiple PDCCHs can be transmitted in a single subframe which may and may not be all relevant to a particular UE. Finally, the modulated symbols are interleaved and mapped to physical Resource Elements (REs).After performing deinterleaving, deprecoding, symbol combining, symbol demodulation and descrambling at the receiver, the UE is required to perform blind decoding of the PDCCH payload as it is not aware of the detailed control channel structure, including the number of control channels and the number of CCEs to which each control channel is mapped. These coded bits are then converted to complex modulated symbols after performing operations including scrambling, QPSK modulation, layer mapping and precoding.If no CRC error is detected the UE determines that PDCCH carries its own control information. The RNTI is used to demask a PDCCH candidate's CRC. The UE uses its Radio Network Temporary Identifier (RNTI) to try and decode candidates. Each REG contains 4 Resource Elements (REs). In PDCCH transmission, only those REGs are used which are not assigned to PCFICH or PHICH. A PDCCH is transmitted on one CCE or an aggregation of several consecutive CCEs, where a CCE corresponds to 9 Resource Element Groups (REGs). The Physical Control Format Indicator Channel (PCFICH) to indicate the number of OFDM symbols used for control signaling in this subframe, Physical Hybrid-ARQ Indicator Channel (PHICH) which carries downlink Acknowledgment (ACK)/Negative Acknowledgment (NACK) for uplink data transmission and Physical Downlink Common Control Channel (PDCCH) which carries the downlink scheduling assignment and uplink scheduling grants.The PDCCH carries scheduling assignments and other control information in the form of DCI messages. Downlink control signaling is carried by three physical channels. One of the advantages of transmitting control channel at the start of every subframe is if the UE is not scheduled it may turn off its receiver circuitry for larger part of the subframe which results in reduced power consumption. The DCI formats are:Format 0 for transmission of Uplink Shared Channel (UL-SCH) allocationFormat 1 for transmission of DL-SCH allocation for Single Input Multiple Output (SIMO) operationFormat 1A for compact transmission of DL-SCH allocation for SIMO operation or allocating a dedicated preamble signature to a UE for random accessFormat 1B for transmission control information of Multiple Input Multiple Output (MIMO) rank 1 based compact resource assignmentFormat 1C for very compact transmission of PDSCH assignmentFormat 1D same as format1B with additional information of power offsetFormat 2 and Format 2A for transmission of DL-SCH allocation for closed and open loop MIMO operation, respectivelyFormat 2B for the scheduling of dual layer transmission (antenna ports 7 & 8)Format 2C for the scheduling of up to 8 layer transmission (antenna ports 7 to 14) using TM9Format 2D for the scheduling of up to 8 layer transmission (antenna ports 7 to 14) using TM10Format 3 and Format 3A for transmission of TPC command for an uplink channelFormat 4 for the scheduling of PUSCH with multi-antenna port transmission modeOnce the DCI message is generated and channel coded according to the required DCI and PDCCH format, PDCCH multiplexing, scrambling, modulation, precoding, interleaving and layer mapping are performed to form complex symbols. The information provided contains everything necessary for the UE to be able to identify the resources required to receive the Physical Downlink Data Channel (PDSCH) in that subframe and to decode it. Depending on the purpose of control message, different DCI formats are defined. Multiple PDCCHs can be transmitted in a subframe thus the UE must monitor all PDCCH in given subframe control region.The DCI message transmits uplink or downlink scheduling information or an uplink Transmit Power Control (TPC) command. As the UE is not explicitly informed of the detailed control channel structure it has to blindly attempt to decode the control region. The control region of a subframe is a collection of CCEs and can contain PDCCHs for multiple UEs thus the UE has to monitor a large area to extract its own control information. The number of CCEs allocated is given by the PDCCH format. The REs are defined in terms of REGs/CCEs allocated to a transmission. That is, the size of the search space is integer times the size of CCE aggregation level or the number of PDCCH candidates. The size of search space is determined by the number of PDCCH candidates and the size of CCE aggregation level. The common and UE-specific search spaces can overlap with each other. The candidates within the PDCCH candidate set do not have to be unique, especially for smaller bandwidths. Each space comprises 2, 4 or 6 PDCCH candidates whose data length depends on the PDCCH format each PDCCH must be transmitted on 1, 2, 4 or 8 CCE(s) (1 CCE = 9 REGs = 9*4 REs = 72 bits).The PDCCH candidates consist of consecutive CCEs. This may exceed practical hardware limitations and lead to increased cost and/or reduced performance of the UE.To simplify the decoding task at the UE, the whole control region is sub-divided into common and UE-specific search spaces which the UE should monitor (attempt to decode each of the PDCCHs). Best photo sharing sites for macThis restriction further simplifies the common search. The common control space is used to carry important initial information including paging information, system information and random access procedures.When searching the common control space the decoder always starts decoding from the first CCE. This reduces the burden on UE for decoding common control information compared to decoding UE-specific control information. 4 and 8 as compared to the UE-specific search space where four CCE aggregation levels are possible. The number of CCE aggregation levels supported by the common search space is limited to two i.e. If no CRC error is detected when the UE uses its RNTI to demask the CRC (16-bit value also refers as C-RNTI) on a PDCCH, the UE determines that PDCCH carries its own control information. In the UE-specific search space the UE finds its PDCCH by monitoring a set of PDCCH candidates (a set of consecutive CCEs on which PDCCH could be mapped) in every subframe. The starting location of the UE-specific search space is determined in every subframe using a hash function, as specified in TS36.213, Clause 9. Unlike the common space search, the starting location of the UE-specific search space may be varied for each subframe or UE. UE-Specific Search SpaceThe UE-specific search space carries control information specific to a particular UE and is monitored by at least one UE in a cell. Cell-Wide SettingsA structure enbConfig is used to configure the eNodeB. Once the PDCCH payload is generated, this example demonstrates how blind decoding is performed to decode the PDCCH in a given subframe. Example DCI Generation, Transmission and RecoveryIn this example, a control channel containing a downlink control information (DCI) message is generated and transmitted over a physical downlink control channel (PDCCH). This process is repeated for all possible PDCCH formats until all directed PDCCHs are successfully decoded in UE-specific search space. If the UE fails to decode any PDCCH candidates for a given PDCCH format it tries to decode candidates for other PDCCH formats. There are 4 PDCCH formats: 0, 1, 2 or 3.
