Abstract: 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.

Abstract: 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 REGs are allocated based on a time first manner. 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.

Abstract: Methods and apparatuses for a User Equipment (UE) to receive signaling of UE-common Downlink Control Information (DCI) in a set of Physical Resource Blocks (PRBs) over a Transmission Time Interval (TTI) are provided. The UE demodulates UE-common DCI using a Reference Signal (RS) that is scrambled by a UE-common scrambling sequence. The UE may assume that RS having a same precoding is transmitted in the set of PRBs over different TTIs. The UE may determine the scrambling sequence implicitly from an identity of a point transmitting the UE-common DCI or explicitly by higher layer signaling. The UE may determine the PRBs of UE-common DCI transmission by broadcast signaling or by higher layer signaling.
