A method, with a wireless communication system, for wirelessly transmitting at least one of a downlink channel descriptor and an uplink channel descriptor for reception by at least one wireless device (104,106), the method comprising: selecting at least one transmission time for transmitting by a base station (110, 112) in a cell of the wireless communication system, for reception by at least one wireless device, at least one of: a pointer indicating a transmission time of a cell to the cell for at least one of a downlink channel descriptor and an uplink channel descriptor of the cell, wherein the pointer is transmitted at a time, in the paging listening interval of a neighboring cell and between a first transmission and a second transmission of the at least one of downlink channel descriptor and uplink channel descriptor, selected to reduce a time interval for the at least one wireless device to search for the at least one of the downlink channel descriptor and uplink channel descriptor of the cell; and a message including downlink channel descriptor information and uplink channel descriptor information associated with the neighboring cell, wherein the message is transmitted by the cell in the paging listening interval of the neighboring cell and during the time between the first transmission and the second transmission of the at least one of downlink channel descriptor and uplink channel descriptor. selecting at least one transmission time for transmitting by a base station (110, 112) in a cell of the wireless communication system, for reception by at least one wireless device, at least one of: a pointer indicating a transmission time of a cell to the cell for at least one of a downlink channel descriptor and an uplink channel descriptor of the cell, wherein the pointer is transmitted at a time, in the paging listening interval of a neighboring cell and between a first transmission and a second transmission of the at least one of downlink channel descriptor and uplink channel descriptor, selected to reduce a time interval for the at least one wireless device to search for the at least one of the downlink channel descriptor and uplink channel descriptor of the cell; and a message including downlink channel descriptor information and uplink channel descriptor information associated with the neighboring cell, wherein the message is transmitted by the cell in the paging listening interval of the neighboring cell and during the time between the first transmission and the second transmission of the at least one of downlink channel descriptor and uplink channel descriptor. a pointer indicating a transmission time of a cell to the cell for at least one of a downlink channel descriptor and an uplink channel descriptor of the cell, wherein the pointer is transmitted at a time, in the paging listening interval of a neighboring cell and between a first transmission and a second transmission of the at least one of downlink channel descriptor and uplink channel descriptor, selected to reduce a time interval for the at least one wireless device to search for the at least one of the downlink channel descriptor and uplink channel descriptor of the cell; and a message including downlink channel descriptor information and uplink channel descriptor information associated with the neighboring cell, wherein the message is transmitted by the cell in the paging listening interval of the neighboring cell and during the time between the first transmission and the second transmission of the at least one of downlink channel descriptor and uplink channel descriptor.
