Abstract
A method for scheduling a downlink transmission is provided. The method includes receiving, by a user equipment (UE), downlink control information (DCI) from a base station, the DCI indicating a location of a transmission duration within a subframe, the location of the transmission duration including a start position of the transmission duration and a length of the transmission duration, the length of the transmission duration being 2, 4, or 7 symbols. The method further includes receiving downlink data from the base station, the downlink data carried by the transmission duration at the location indicated by the DCI.
Claims21
A method comprising:
- receiving, by an apparatus from a base station, higher layer signaling, the higher layer signaling indicating location information of at least one pre-emption symbol within a slot, the at least one pre-emption symbol indicated in the higher layer signaling being excluded from a downlink data transmission;
- after the receiving the higher layer signaling indicating the location information, receiving, by the apparatus, downlink control information (DCI) from the base station, wherein the DCI schedules resources for the downlink data transmission within the slot, wherein the resources scheduled for the downlink data transmission include a start position and a length, wherein the at least one pre-emption symbol is located within the resources scheduled for the downlink data transmission by the DCI, wherein the start position of the resources is in terms of a starting symbol in the slot, and wherein the length of the resources is in terms of a number of allocated symbols;
- and
- receiving, by the apparatus, from the base station, the downlink data transmission in accordance with a combination of the resources scheduled for the downlink data transmission by the DCI and the at least one pre-emption symbol indicated by the higher layer signaling.
1 more element
An apparatus comprising:
- at least one processor;
- and
- a non-transitory computer readable storage medium storing programming for execution by the at least one processor, the programming including instructions to:
- receive, from a base station, higher layer signaling, the higher layer signaling indicating location information of at least one pre-emption symbol within a slot, the at least one pre-emption symbol indicated in the higher layer signaling being excluded from a downlink data transmission;
- after receiving the higher layer signaling indicating the location information, receive downlink control information (DCI) from the base station, wherein the DCI schedules resources for the downlink data transmission within the slot, wherein the resources scheduled for the downlink data transmission include a start position and a length, wherein the at least one pre-emption symbol is located within the resources scheduled for the downlink data transmission by the DCI, wherein the start position of the resources is in terms of a starting symbol in the slot, and wherein the length of the resources is in terms of a number of allocated symbols;
- and
- receive, from the base station, the downlink data transmission in accordance with a combination of the resources scheduled for the downlink data transmission by the DCI and the at least one pre-emption symbol indicated by the higher layer signaling.

A method comprising:
- transmitting, by a base station to a user equipment (UE), higher layer signaling, the higher layer signaling indicating location information of at least one pre-emption symbol within a slot, the at least one pre-emption symbol indicated in the higher layer signaling being excluded from a downlink data transmission;
- after the transmitting the higher layer signaling indicating the location information, transmitting, by the base station, downlink control information (DCI) to the UE, wherein the DCI schedules resources for the downlink data transmission within the slot, wherein the resources scheduled for the downlink data transmission include a start position and a length, wherein the at least one pre-emption symbol is located within the resources scheduled for the downlink data transmission by the DCI, wherein the start position of the resources is in terms of a starting symbol in the slot, and wherein the length of the resources is in terms of a number of allocated symbols;
- and
- transmitting, by the base station, to the UE, the downlink data transmission in accordance with a combination of the resources scheduled for the downlink data transmission by the DCI and the at least one pre-emption symbol indicated by the higher layer signaling.
