Mapping between logical and physical uplink control resource blocks in wireless networks

摘要

A transmission of information from a secondary to a primary node occurs in a plurality of N logical time durations on an uplink channel in a wireless network. A scheme for mapping between logical uplink control channel (PUCCH) resource blocks (RBs) and physical RBs (PRBs) used by PUCCH is described. A logical uplink control resource block index n_LRB is derived by the secondary node in response to information from the primary node. The secondary node then maps the logical uplink control resource block index n_LRB to a first uplink physical resource block index n_PRB,1 of a plurality of uplink physical resource blocks, wherein n_PRB,1=n_LRB/2 if n_LRB is even and n_PRB,1=N_PRB−ceil(n_LRB/2) if n_LRB is odd; wherein N_PRB is the total number of the plurality of uplink physical resource blocks; and wherein ceil denotes the ceiling operation. The secondary node then transmits an uplink control information in a subframe using one of the plurality of uplink physical resource blocks indexed by n_PRB,1.
