Abstract
Aspects of the disclosure relate to implied and explicit mapping of uplink (UL) resources for acknowledgment communications from a user equipment (UE). In some examples disclosed herein, implied mapping may include indexing of information elements in a downlink (DL) communication. The explicit mapping may include information elements in the DL communication configured to explicitly provide a location of an UL resource. Other aspects, embodiments, and features are also claimed and described.
Claims42
A method of wireless communication operable at a scheduled entity, the method comprising:
- receiving, from a scheduling entity, a downlink (DL) transmission comprising a control channel element (CCE) having a CCE index and DL control information (DCI) having an offset value;
- generating an acknowledgment (ACK) for transmission in response to the DL transmission;
- determining a first uplink (UL) resource for transmitting the ACK based on the CCE index, information from a radio resource control (RRC) message, and the offset value in the DCI;
- and
- transmitting, to the scheduling entity, the ACK utilizing the first UL resource.
An apparatus configured for wireless communication, comprising:
- a memory device;
- a transceiver;
- and
- at least one processor communicatively coupled to the memory device and the transceiver, configured to:
- receive, from a scheduling entity, a downlink (DL) transmission comprising a control channel element (CCE) having a CCE index and DL control information (DCI) having an offset value;
- generate an acknowledgment (ACK) for transmission in response to the DL transmission;
- determine a first uplink (UL) resource for transmitting the ACK based on the CCE index, information from a radio resource control (RRC) message, and the offset value in the DCI;
- and
- transmit, to the scheduling entity, the ACK utilizing the first UL resource.
A method of wireless communication operable at a scheduling entity, the method comprising:
- selecting a first uplink (UL) resource for an acknowledgment (ACK), the first UL resource being mapped by a control channel element (CCE) index, information from a radio resource control (RRC) message, and an offset value;
- communicating, to a scheduled entity, a downlink (DL) transmission comprising a CCE having the CCE index and a DL control information (DCI) having the offset value;
- and
- receiving, from the scheduled entity, an ACK communicated via the first UL resource in response to the DL transmission.
