Abstract
A method, network node and wireless device for transmitting and decoding repeated physical downlink control channel (PDCCH) messages are disclosed. According to one embodiment a method implemented in a wireless device (WD) includes receiving multiple transmissions of a PDCCH message, each of the multiple transmissions of the PDDCH message being repeated in a repetition set. The method further includes monitoring the multiple received PDCCH transmissions to obtain scheduling information for a physical uplink shared channel (PUSCH) transmission or a physical downlink shared channel (PDSCH) reception.
Claims24
A wireless device, WD, configured to communicate with a network node, the WD comprising processing circuitry configured to:
- receive multiple transmissions of a physical downlink control channel, PDCCH, message, each of the multiple transmissions of the PDCCH message being repeated in a repetition set;
- monitor the multiple received PDCCH message transmissions to obtain scheduling information for one of a physical uplink shared channel, PUSCH, transmission and a physical downlink shared channel, PDSCH, reception;
- and
- determine a scheduling offset for a PDSCH or a PUSCH based on a time location of a PDCCH candidate of the repetition set.
A method implemented in a wireless device (WD), WD, the method comprising:
- receiving multiple transmissions of a physical downlink control channel, PDCCH, message, each of the multiple transmissions of the PDCCH message being repeated in a repetition set;
- monitoring the multiple received PDCCH message transmissions to obtain scheduling information for one of a physical uplink shared channel, PUSCH, transmission and a physical downlink shared channel, PDSCH, reception;
- and
- determine a scheduling offset for a PDSCH or a PUSCH based on a time location of a PDCCH candidate of the repetition set.
A network configured to communicate with a wireless device WD, the network node comprising processing circuitry configured to:
- configure a physical downlink control channel, PDCCH, message for multiple transmissions;
- and
- cause the multiple transmissions of the PDCCH message, each of the multiple transmissions of the PDCCH message being repeated in a repetition set, the multiple transmission causing the WD to monitor the multiple transmissions of the PDCCH message to obtain scheduling information for one of a physical uplink shared channel, PUSCH, transmission and a physical downlink shared channel, PDSCH, reception by the WD and determine a scheduling offset for a PDSCH or a PUSCH based on a time location of a PDCCH candidate of the repetition set.
A method implemented in a network node, the network node being configured to communicate with a wireless device, WD, the method comprising:
- configuring a physical downlink control channel, PDCCH, message for multiple transmissions;
- and
- causing the multiple transmissions of the PDCCH message, each of the multiple transmissions of the PDCCH message being repeated in a repetition set, the multiple transmission causing the WD to monitor the multiple transmissions of the PDCCH message to obtain scheduling information for one of a physical uplink shared channel, PUSCH, transmission and a physical downlink shared channel, PDSCH, reception by the WD and determine a scheduling offset for a PDSCH or a PUSCH based on a time location of a PDCCH candidate of the repetition set.
