Patent Images
1. A method for coordinating uplink and downlink transmissions, the method comprising:
- a wireless transmit receive unit (WTRU) receiving discontinuous reception (DRX) configuration information from an evolved Node-B (eNB) via a radio resource control (RRC) message, wherein the DRX configuration information comprises an indication of a length of a minimum active period and an indication of a DRX cycle periodicity;
the WTRU receiving an uplink resource assignment from the eNB, wherein the uplink resource assignment is applicable to a first uplink channel, and the uplink resource assignment is a periodic assignment of the first uplink channel; and
the WTRU transmitting to the eNB in accordance with the uplink resource assignment, wherein transmissions sent on the first uplink channel according to the periodic assignment coincide with an active period of a DRX cycle associated with the DRX configuration information.

8. A wireless transmit receive unit (WTRU) comprising a processor configured, at least in part, to:
-
receive discontinuous reception (DRX) configuration information from an evolved Node-B (eNB) via a radio resource control (RRC) message, wherein the DRX configuration information comprises an indication of a length of a minimum active period and an indication of a DRX cycle periodicity; receive an uplink resource assignment from the eNB, wherein the uplink resource assignment is applicable to a first uplink channel, and the uplink resource assignment is a periodic assignment of the first uplink channel; and transmit to the eNB in accordance with the uplink resource assignment, wherein the WTRU is configured to send transmissions on the first uplink channel according to the periodic assignment in a manner such that the transmissions coincide with an active period of a DRX cycle associated with the DRX configuration information. - View Dependent Claims (9, 10, 11, 12, 13, 14)

15. An evolved Node-B (eNB) comprising a processor configured, at least in part, to:
-
send discontinuous reception (DRX) configuration information to a wireless transmit receive unit (WTRU) via a radio resource control (RRC) message, wherein the DRX configuration information comprises an indication of a length of a minimum active period and an indication of a DRX cycle periodicity; send an uplink resource assignment to the WTRU, wherein the uplink resource assignment is applicable to a first uplink channel, and the uplink resource assignment is a periodic assignment to the WTRU for use of the first uplink channel; and receive transmissions from the WTRU in accordance with the uplink resource assignment, wherein the eNB is configured to receive the transmissions on the first uplink channel in accordance with the periodic assignment such that the transmissions to the eNB on the first uplink channel coincide with an active period of a DRX cycle configured for the WTRU. - View Dependent Claims (16, 17, 18, 19, 20)
