Abstract
Methods and apparatus are provided that provide single or multiple Physical Downlink Control Channel (PDCCH) messages for single or multiple Physical Downlink Shared Channel (PDSCH) messages to support network coordination schemes such as Non-Coherent Joint Transmission.
Claims24
A method for a User Equipment (UE) in a wireless network, the method comprising:
- receiving, at the UE, at least one Physical Downlink Control Channel (PDCCH) message that includes Downlink Control Information (DCI) in respect of at least one Physical Downlink Shared Channel (PDSCH) message;
- and
- in response to receiving the at least one PDCCH message, receiving at least one PDSCH message in accordance with the DCI included in the at least one PDCCH message,
- the receiving the at least one PDCCH message comprising:
- i) receiving one PDCCH message that includes DCI in respect of at least one PDSCH message from multiple transmission-reception points (TRPs);
- or
- ii) receiving multiple PDCCH messages, each PDCCH message including DCI in respect of at least one PDSCH message.
A method for a transmission-reception point (TRP) in a wireless network, the method comprising:
- transmitting, to a User Equipment (UE), at least one Physical Downlink Control Channel (PDCCH) message that includes Downlink Control Information (DCI) in respect of at least one Physical Downlink Shared Channel (PDSCH) message;
- and
- transmitting, to the UE, at least one of the at least one PDSCH message in accordance with the DCI in the at least one PDCCH message,
- the transmitting the at least one PDCCH message comprising:
- i) transmitting one PDCCH message that includes DCI in respect of at least one PDSCH message from multiple TRPs in a cooperating set of TRPs serving the UE;
- or
- ii) transmitting multiple PDCCH messages, each PDCCH message including DCI in respect of at least one PDSCH message.
The method of claim ii, wherein there is a one-to-one mapping between UCI and PDCCH or there is a many-to-one mapping between PDCCH and UCI.
A User Equipment (UE) comprising:
- a non-transitory memory storage comprising instructions;
- and
- one or more processors in communication with the non-transitory memory storage, wherein the one or more processors execute the instructions to:
- receive at least one Physical Downlink Control Channel (PDCCH) message that includes Downlink Control Information (DCI) in respect of at least one Physical Downlink Shared Channel (PDSCH) message;
- in response to receiving the at least one PDCCH message, receive at least one PDSCH message from a cooperating set of transmission-reception points (TRPs) in a wireless network in accordance with the DCI included in the at least one PDCCH message;
- and
- wherein the one or more processors execute the instructions to receive the at least one PDCCH message through receiving one PDCCH message that includes DCI in respect of at least one PDSCH message from multiple TRPs, or receiving multiple PDCCH messages, each PDCCH message including DCI in respect of at least one PDSCH message.
A transmission-reception point (TRP) comprising:
- a non-transitory memory storage comprising instructions;
- and
- one or more processors in communication with the non-transitory memory storage, wherein the one or more processors execute the instructions to:
- transmit, to a User Equipment (UE), at least one Physical Downlink Control Channel (PDCCH) message that includes Downlink Control Information (DCI) in respect of at least one Physical Downlink Shared Channel (PDSCH) message;
- and
- transmit, to the UE, at least one of the at least one PDSCH message in accordance with the DCI in the at least one PDCCH message,
- wherein the one or more processors execute the instructions to transmit the at least one PDCCH message through transmitting one PDCCH message that includes DCI in respect of at least one PDSCH message from multiple TRPs in a cooperating set of TRPs serving the UE, or transmitting multiple PDCCH messages, each PDCCH message including DCI in respect of at least one PDSCH message.
