METHOD AND APPARATUS FOR ALLOCATING RESOURCES OF A CONTROL CHANNEL IN A MOBILE COMMUNICATION SYSTEM USING ORTHOGONAL FREQUENCY DIVISION MULTIPLEXING

摘要

Methods and apparatuses are provided for wireless communication. Control symbols are mapped to a plurality of resource element groups (REGs) which is not assigned to a physical channel format indication channel (PCFICH) or a physical hybrid automatic repeat request indicator channel (PHICH). The mapped control symbols are transmitted on a packet dedicated control channel (PDCCH). A number of a plurality of resource elements (REs) in each of the REGs depends on an index of an orthogonal frequency division multiplexing (OFDM) symbol and a number of configured reference signals. A number of the REGs in a physical resource block (PRB) on an OFDM symbol depends on the index of the OFDM symbol and the number of configured reference signals.

1. A method for wireless communication, the method comprising:
mapping control symbols to a plurality of resource element groups (REGs) which is not assigned to a physical channel format indication channel (PCFICH) or a physical hybrid automatic repeat request indicator channel (PHICH); and transmitting the mapped control symbols on a packet dedicated control channel (PDCCH), wherein a number of a plurality of resource elements (REs) in each of the REGs depends on an index of an orthogonal frequency division multiplexing (OFDM) symbol and a number of configured reference signals, and wherein a number of the REGs in a physical resource block (PRB) on an OFDM symbol depends on the index of the OFDM symbol and the number of configured reference signals.
