Abstract
A mobile station which communicates with a base station includes a transceiver configured to receive a downlink control channel, and a controller configured to determine whether C-RNTI is included in the downlink control channel. The controller is further configured to determine that resource allocation in the downlink control channel overrides persistent downlink resource allocation for a Transmission Time Interval (TTI) if the C-RNTI is included in the downlink control channel. The transceiver is further configured to receive a Hybrid Automatic Repeat Request (HARQ) transmission by using persistent downlink resources.
Claims18
A method of a base station for a communication system in which resources can be dynamically allocated at each transmission time interval on a downlink control channel, the method comprising:
- transmitting control information in a case where first persistent scheduling is active,
- wherein the control information includes a sequence of bits within a field,
- wherein the field is configured to be used to determine a Modulation and Coding Scheme (MCS), and
- wherein part of the sequence is set for activating second persistent scheduling;
- and
- performing communication with a user equipment (UE) based on the second persistent scheduling.
A method of a User Equipment (UE) for a communication system in which resources can be dynamically allocated at each transmission time interval on a downlink control channel, the method comprising:
- receiving control information in a case where first persistent scheduling is active,
- wherein the control information includes a sequence of bits within a field, and
- wherein the field is configured to be used to determine a Modulation and Coding Scheme (MCS);
- and
- considering the control information as an activation of second persistent scheduling in a case where part of the sequence is set for activating the second persistent scheduling.
A base station for a communication system in which resources can be dynamically allocated at each transmission time interval on a downlink control channel, the base station comprising:
- at least one memory;
- and
- at least one hardware processor coupled to the at least one memory,
- wherein the at least one hardware processor is configured to:
- transmit control information when control information in a case where first persistent scheduling is active,
- wherein the control information includes a sequence of bits within a field,
- wherein the field is configured to be used to determine a Modulation and Coding Scheme (MCS), and
- wherein part of the sequence is set for activating second persistent scheduling;
- and
- perform communication with a user equipment (UE) based on the second persistent scheduling.
A User Equipment (UE) for a communication system in which resources can be dynamically allocated at each transmission time interval on a downlink control channel, the UE comprising:
- at least one memory;
- and
- at least one hardware processor coupled to the at least one memory,
- wherein the at least one hardware processor is configured to:
- receive control information in a case where first persistent scheduling is active,
- wherein the control information includes a sequence of bits within a field, and
- wherein the field is configured to be used to determine a Modulation and Coding Scheme (MCS);
- and
- consider the control information as an activation of second persistent scheduling in a case where part of the sequence is set for activating the second persistent scheduling.
