SELECTING A CELL IDENTIFIER BASED ON A DOWNLINK CONTROL INFORMATION
A method, an apparatus, and a computer program product for wireless communication are provided in which a cell identifier is selected based on one or more properties associated with received downlink control information (DCI), where the properties may not be exclusively associated with determining a cell identifier. The cell identifier may be selected from a plurality of cell identifiers received through radio resource control signaling. The properties of the DCI may include a type of download control channel, a type of subframe and a type of DCI format used to provide the DCI.
1 . A method of wireless communications, comprising:
determining an index based on a format type of downlink control information (DCI); and
selecting a set of parameters from a plurality of sets of the parameters based on the index, wherein the set of parameters defines one or more characteristics of a virtual cell, and wherein the plurality of sets of the parameters is configured through radio resource control (RRC) signaling.
2 . The method of claim 1 , further comprising initializing a pseudo-random sequence generator using one parameter of the selected set of parameters.
3 . The method of claim 1 , wherein the set of parameters is used to define characteristics of an uplink communication channel.
4 . An apparatus for wireless communication, comprising:
means for determining an index based on a format type of downlink control information (DCI); and
means for selecting a set of parameters from a plurality of sets of the parameters based on the index, wherein the set of parameters defines one or more characteristics of a virtual cell, and wherein the plurality of sets of the parameters is configured through radio resource control (RRC) signaling.
5 . The apparatus of claim 4 , further comprising means for initializing a pseudo-random sequence generator using one parameter of the selected set of parameters.
6 . The apparatus of claim 5 , wherein the set of parameters is used to define characteristics of an uplink communication channel.
7 . An apparatus for wireless communication, comprising:
a processing system configured to:
determine an index based on a format type of downlink control information (DCI); and
select a set of parameters from a plurality of sets of the parameters based on the index, wherein the set of parameters defines one or more characteristics of a virtual cell, and wherein the plurality of sets of the parameters is configured through radio resource control (RRC) signaling.
8 . The apparatus of claim 7 , wherein the processing system is further configured to initialize a pseudo-random sequence generator using one parameter of the selected set of parameters.
9 . The apparatus of claim 7 , wherein the set of parameters is used to define characteristics of an uplink communication channel.
10 . A computer-readable medium comprising code for:
determining an index based on a format type of downlink control information (DCI); and
selecting a set of parameters from a plurality of sets of the parameters based on the index, wherein the set of parameters defines one or more characteristics of a virtual cell, and wherein the plurality of sets of the parameters is configured through radio resource control (RRC) signaling.
11 . The computer-readable medium of claim 10 , further comprising code for initializing a pseudo-random sequence generator using one parameter of the selected set of parameters.
12 . The computer-readable medium of claim 10 , wherein the set of parameters is used to define characteristics of an uplink communication channel.
