A method of a mobile station, comprising: transmitting a signaled multislot class information of a signaled multislot class of the mobile station; transmitting, when available, an alternative multislot class information of an alternative multislot class of the mobile station; receiving an assignment of a multislot configuration; determining, by the mobile station, multislot capability parameters during a radio block period based on at least whether the alternative multislot class information is available and whether the mobile station is transmitting in the radio block period; and operating the mobile station based on the assignment and on the multislot capability parameters, wherein when the mobile station transmits no alternative multislot class information, the multislot capability parameters comprise Rx, Tx, SUM, Tta, Ttb, Tra and Trb of the signaled multislot class, and further wherein Rx is a maximum number of receive timeslots the mobile station can use in a TDMA timeframe, Tx is a maximum number of transmit timeslots the mobile station can use in the TDMA timeframe, SUM is a total number of uplink and downlink timeslots that can be used by the mobile station in the TDMA timeframe, Tta is time needed for the mobile station to perform measurement and get ready to transmit, Ttb is the time needed for the mobile station to get ready to transmit, Tra is the time needed for the mobile station to perform measurement and get ready to receive, and Trb is the time needed for the mobile station to get ready to receive, and wherein when the mobile station transmits an alternative multislot class information, the multislot capability parameters further comprise Rx of the alternative multislot class and Tx of the signaled multislot class. transmitting a signaled multislot class information of a signaled multislot class of the mobile station; transmitting, when available, an alternative multislot class information of an alternative multislot class of the mobile station; receiving an assignment of a multislot configuration; determining, by the mobile station, multislot capability parameters during a radio block period based on at least whether the alternative multislot class information is available and whether the mobile station is transmitting in the radio block period; and operating the mobile station based on the assignment and on the multislot capability parameters, wherein when the mobile station transmits no alternative multislot class information, the multislot capability parameters comprise Rx, Tx, SUM, Tta, Ttb, Tra and Trb of the signaled multislot class, and further wherein Rx is a maximum number of receive timeslots the mobile station can use in a TDMA timeframe, Tx is a maximum number of transmit timeslots the mobile station can use in the TDMA timeframe, SUM is a total number of uplink and downlink timeslots that can be used by the mobile station in the TDMA timeframe, Tta is time needed for the mobile station to perform measurement and get ready to transmit, Ttb is the time needed for the mobile station to get ready to transmit, Tra is the time needed for the mobile station to perform measurement and get ready to receive, and Trb is the time needed for the mobile station to get ready to receive, and wherein when the mobile station transmits an alternative multislot class information, the multislot capability parameters further comprise Rx of the alternative multislot class and Tx of the signaled multislot class.
