Abstract
A method for operating a network node of a wireless communication network is disclosed. The method comprises determining and/or adjusting a HARQ signaling format for a terminal configured for carrier aggregation based on a number of DL carriers and/or a number of HARQ bits configured for the terminal.
Claims16
A method for operating a network node of a wireless communication network, the method comprising:
- determining a Hybrid Automatic Repeat Request (HARQ) signaling format for transmission of HARQ feedback on a Physical Uplink Shared Channel (PUSCH) from a terminal to a network node by determining a HARQ-ACK offset for the HARQ signaling format based on a number of HARQ bits configured for the terminal;
- and
- configuring the terminal to transmit the HARQ feedback on the PUSCH using the HARQ signaling format to multiplex HARQ feedback with user data transmitted on the PUSCH.
A network node for a wireless communication network, the network node comprising:
- a processor;
- memory containing instruction executable by the processor whereby the network node is operative to:
- determine a Hybrid Automatic Repeat Request (HARQ) signaling format for transmission of HARQ feedback on a Physical Uplink Shared Channel (PUSCH) from a terminal to a network node by determining HARQ-ACK offset for the HARQ signaling format based on a a number of HARQ bits configured for the terminal;
- and
- configure the terminal to transmit the HARQ feedback on the PUSCH using the HARQ signaling format to multiplex HARQ feedback with user data transmitted on the PUSCH.
A method for operating a terminal in a wireless communication network, the terminal being configured for carrier aggregation, the method comprising:
- determining a Hybrid Automatic Repeat Request (HARQ) signaling format for transmission of HARQ feedback on a Physical Uplink Shared Channel (PUSCH) from the terminal to a network node by determining a HARQ-ACK offset for the HARQ signaling format based on a number of HARQ bits configured for the terminal;
- and
- transmitting HARQ feedback on the PUSCH using the HARQ signaling format to multiplex the HARQ feedback with user data on the PUSCH.
A terminal for a wireless communication network, the terminal adapted for carrier aggregation and comprising:
- a processor;
- memory containing instruction executable by the processor whereby the terminal is operative to:
- determine a Hybrid Automatic Repeat request (HARQ) signaling format for transmission of HARQ feedback on a Physical Uplink Shared Channel (PUSCH) from the terminal to a network node by determining a HARQ-ACK offset for the HARQ signaling format based on a number of HARQ bits configured for the terminal;
- and
- transmit HARQ feedback on an uplink shared channel using the HARQ signaling format to multiplex the HARQ feedback with user data on the uplink shared channel.
