Physical Downlink Control Channel (PDCCH) : The PDCCH carries information known as the Downlink Control Information or DCI . It carries the control information for a particular UE or group of UEs. Basically A DCI provides the following information. Downlink resource scheduling, Uplink power control instructions.3 Ağu 2017

Transport channels provide for information transfer between the physical layer and the medium access control (MAC) layer in the three layer structure illustrated in Figure 1. Figure 1. Layers. The following downlink transport channels are defined: Broadcast channel (BCH)
Read moreWhat is physical downlink control channel?
Physical Downlink Control Channel (PDCCH) Informs the UE about the resource allocation of PCH and DL-SCH, and HARQ information related to DL-SCH . Carries the uplink scheduling grant.
Read moreWhat is the difference between physical channel and logical channel?
In GSM, these channels are separated into physical channels and logical channels. The Physical channels are determined by the timeslot, whereas the logical channels are determined by the information carried within the physical channel .
Read moreWhat is channel bandwidth in LTE?
In 3GPP the channel bandwidth is defined as the occupied bandwidth of a modulated waveform which corresponds to the frequency range containing 99% of the total power of the modulated signal . An LTE-M-U narrowband of 6 PRBs have a 1.4 MHz channel bandwidth according to this definition which is reused by ETSI.
Read moreWhat is meant by Channel spacing?
A. The amount of bandwidth allotted to each channel in a communications system that transmits multiple frequencies such as fiber optics . It is measured as the spacing between center frequencies (or wavelengths) of adjacent channels.
Read moreWhat is channel spacing in frequency?
Channel spacing, also known as bandwidth, is a term used in radio frequency planning. It describes the frequency difference between adjacent allocations in a frequency plan .
