Method for informing available resource for PDSCH, method for determining available resource for PDSCH, base station and UE

A method for determining available resource for PDSCH, comprising:

• receiving, by the user equipment, information about the available resource for Physical Downlink Shared Channel (PDSCH) in a scheduling unit,
• wherein the information about the available resource for PDSCH in the scheduling unit includes information representing a reserved resource allocation of the scheduling unit,
• wherein the reserved resource allocation of the scheduling unit indicates in frequency domain one or more resource sets and indicates in time domain a part of Orthogonal Frequency Division Multiplexing (OFDM) symbols within the one or more resource sets of the scheduling unit as a reserved resource set, the reserved resource set would not to be used for transmitting the PDSCH;
• and
• determining, by the user equipment, the available resource for PDSCH in the scheduling unit according to the information about the available resource for PDSCH in the scheduling unit;
• wherein determining by the user equipment the available resource for PDSCH in the scheduling unit according to the information about the available resource for PDSCH in the scheduling unit comprises:
• when the information about the available resource for PDSCH in the scheduling unit is received from a base station using one of a dynamic common control channel, a dynamic UE-specific control channel and
• a semi-static higher layer signaling, determining the available resource for PDSCH in the scheduling unit according to the information about the available resource for PDSCH in the scheduling unit;
• or
• when the information about the available resource for PDSCH in the scheduling unit is received from the based station using both the semi-static higher layer signaling and
• one of the dynamic common control channel and the dynamic UE-specific control channel, determining the available resource for PDSCH in the scheduling unit according to the information about the available resource for PDSCH in the scheduling unit latest received using the one of the dynamic common control channel and
• the dynamic UE-specific control channel after determining candidate reserved resource allocation in the scheduling unit according to the information about the available resource for PDSCH in the scheduling unit received using the semi-static higher layer signaling;
• or
• when the information about the available resource for PDSCH in the scheduling unit is received from the based station using both the dynamic common control channel and
• the dynamic UE-specific control channel, determining the available resource for PDSCH in the scheduling unit according to the information about the available resource for PDSCH in the scheduling unit received using the dynamic UE-specific control channel.

A base station, comprising:

• a processor;
• and
• a memory for storing instructions executable by the processor;
• wherein the processor is configured to:
• signal, to a user equipment, information about available resource for Physical Downlink Shared Channel (PDSCH) in a scheduling unit according to a reserved resource allocation of the scheduling unit;
• wherein the reserved resource allocation of the scheduling unit indicates in frequency domain one or more resource sets and indicates in time domain a part of Orthogonal Frequency Division Multiplexing (OFDM) symbols within the one or more resource sets of the scheduling unit as a reserved resource set, and
• the information about the available resource for PDSCH in the scheduling unit includes information representing the reserved resource allocation of the scheduling unit,
• wherein the reserved resource set would not to be used for transmitting the PDSCH;
• wherein the processor is configured to signal, to the user equipment, the information about the available resource for PDSCH in the scheduling unit in the following way:
• signaling the information about the available resource for PDSCH in the scheduling unit by using one of a dynamic common control channel, a dynamic UE-specific control channel and a semi-static higher layer signaling;
• or
• signaling the information about the available resource for PDSCH in the scheduling unit by using both the semi-static higher layer signaling and one of the dynamic common control channel and the dynamic UE-specific control channel;
• or
• signaling the information about the available resource for PDSCH in the scheduling unit by using both the dynamic common control channel and the dynamic UE-specific control channel.
