Abstract
Methods and apparatus are described for a User Equipment (UE) with reduced processing capabilities (e.g., Machine Type Communication (MTC) UE) to transmit and receive signaling are provided. The Downlink Control Information (DCI) formats scheduling a transmission of a Physical Uplink Shared CHannel (PUSCH) or a reception of a Physical Downlink Shared CHannel (PDSCH) are designed and have a smaller size than respective DCI formats for conventional UEs. DCI formats scheduling PUSCHs to or PDSCHs for a group of MTC UEs are also designed and can have a same size as DCI formats scheduling PUSCH or PDSCH for an individual MTC UE.
Claims6
A method performed by a base station, the method comprising:
- identifying a first user equipment (UE) associated with a first UE class and a second UE associated with a second UE class;
- generating a first downlink control information (DCI) to schedule the first UE to transmit a first physical downlink shared channel (PDSCH), wherein the first DCI comprises a first set of information elements (IEs) including a first modulation and coding scheme (MCS) IE, and the first MCS IE is represented by a first number of bits;
- generating a second DCI to schedule the second UE to transmit a second PDSCH, wherein the second DCI comprises a second set of IEs including a second MCS IE, the second MCS IE is represented by a second number of bits less than the first number of bits, and the second UE class is configured for bandwidth-limited low complexity UEs;
- and
- transmitting the first DCI for the first UE and the second DCI for the second UE.
An apparatus in a base station, the apparatus comprising:
- a transceiver;
- and
- a processor coupled with the transceiver, and configured to:
- identify a first user equipment (UE) associated with a first UE class and a second UE associated with a second UE class,
- generate a first downlink control information (DCI) to schedule the first UE to transmit a first physical downlink shared channel (PDSCH), wherein the first DCI comprises a first set of information elements (IEs) including a first modulation and coding scheme (MCS) IE, and the first MCS IE is represented by a first number of bits,
- generate a second DCI to schedule the second UE to transmit a second PDSCH, wherein the second DCI comprises a second set of IEs including a second MCS IE, the second MCS IE is represented by a second number of bits less than the first number of bits, and the second UE class is configured for bandwidth-limited low complexity UEs, and
- control the transceiver to transmit the first DCI for the first UE and the second DCI for the second UE.
