Abstract
Description
Parameter | Physical Channel | Rate-of-Change | contents |
Full SRS Bandwidth | Broadcast | Low | indicates the maximum SRS bandwidth that UE covers for sending SRS in the cell |
SRS Bandwidth | Dedicated | indicates a bandwidth on which UE transmits SRS at every SRS transmission period. | |
Frequency-domain position | Dedicated | indicates RB offset position for hopping in transmitting SRS | |
Frequency-hopping information | Dedicated | indicates pattern of hopping | |
Duration | Dedicated | indicates time during which SRS transmission continues | |
Period | Dedicated | indicates time period at which SRS transmission takes place | |
Subframe offset | Dedicated | indicates a position of a subframe in which UE transmits SRS | |
Transmission comb | Dedicated | indicates which set of subcarrier is used for SRS transmission | |
Cyclic shift | Dedicated | indicates cyclic shift to be used for SRS transmission | |
SRS indicator | Broadcast or Dedicated | Low | indicates which subframe is used for SRS transmission and which subframe is not |
Simultaneous transmission indicator | Broadcast or Dedicated | Low | indicates whether simultaneous transmission of ACK/NACK signal and SRS takes place. In case of non-simultaneous transmission, ACK/NACK signal is prior to SRS |
