Abstract

A user equipment (UE) is described. The UE includes receiving circuitry configured to monitor a physical downlink control channel (PDCCH) conveying a pre-emption indication that indicates pre-emption of a physical uplink shared channel (PUSCH) transmission. The receiving circuitry is also configured to receive radio resource control (RRC) signaling that comprises a configuration for a configured grant and a configuration for grant-based PUSCH. The UE also includes a higher layer processor configured to determine whether to follow the configuration for the configured grant or the configuration for grant-based PUSCH for a scheduled retransmission of a TB previously transmitted on a PUSCH with a configured grant. The UE further includes transmitting circuitry configured to transmit or skip the PUSCH transmission based on the pre-emption indication.

First claim

What is claimed is:

1. A user equipment (UE) that communicates with a base station apparatus, comprising:
one or more processors; and
at least one memory, wherein the at least one memory stores instructions that, when executed by the one or more processors, cause the one or more processors to:
receive a radio resource control (RRC) message comprising first information used for indicating a first number of symbols and second information used for indicating a second number of groups of symbols, wherein
the second number of groups of symbols comprises a third number of groups of symbols and a fourth number of groups of symbols,
each group of the third number of groups of symbols includes a fifth number of symbols and each group of the fourth number of groups of symbols includes a sixth number of symbols, and
the third number, the fourth number, the fifth number, and the sixth number are calculated based on the first number and the second number;

receive an RRC message comprising third information used for indicating a seventh number of resource blocks and fourth information used for indicating an eighth number of groups of resource blocks, wherein
the eighth number of groups of resource blocks comprises a ninth number of groups of resource blocks and a tenth number of groups of resource blocks,
each group of the ninth number of groups of resource blocks includes an eleventh number of resource blocks and each group of the tenth number of groups of resource blocks includes a twelfth number of resource blocks, and
the ninth number, the tenth number, the eleventh number, and the twelfth number are calculated based on the seventh number and the eighth number;

monitor a first downlink control information (DCI) format comprising fifth information indicating a preemption indication, wherein
the second number of sets of bits in the fifth information have a one-to-one mapping with the second number of groups of symbols where the eighth number of bits in each set of bits have a one-to-one mapping with the eighth number of groups of resource blocks; and

perform, based on a detection of the first DCI format, no uplink transmission on at least one corresponding group(s) of symbols and at least one corresponding group(s) of resource blocks.

2. The UE according to the claim 1 , wherein
(the third number)=(the second number)−(the first number)+floor((the first number)/(the second number))·(the second number),

(the fourth number)=(the first number)−floor((the first number)/(the second number))·(the second number),

(the fifth number)=floor((the first number)/(the second number)),
(the sixth number)=ceiling((the first number)/(the second number))
(the ninth number)=(the eighth number)−(the seventh number)+floor((the seventh number)/(the eighth number))·(the eighth number),

(the tenth number)=(the seventh number)−floor((the seventh number)/(the eighth number))·(the eighth number),

(the eleventh number)=floor((the seventh number)/(the eighth number)), and
(the twelfth number)=ceiling((the seventh number)/(the eighth number)).

3. A base station apparatus that communicates with a user equipment (UE), comprising:
one or more processors; and
at least one memory, wherein the at least one memory stores instructions that, when executed by the one or more processors, cause the one or more processors to:
transmit a radio resource control (RRC) message comprising first information used for indicating a first number of symbols and second information used for indicating a second number of groups of symbols, wherein
the second number of groups of symbols comprises a third number of groups of symbols and a fourth number of groups of symbols,
each group of the third number of groups of symbols includes a fifth number of symbols and each group of the fourth number of groups of symbols includes a sixth number of symbols, and
the third number, the fourth number, the fifth number, and the sixth number are calculated based on the first number and the second number;

transmit an RRC message comprising third information used for indicating a seventh number of resource blocks and fourth information used for indicating an eighth number of groups of resource blocks, wherein
the eighth number of groups of resource blocks comprises a ninth number of groups of resource blocks and a tenth number of groups of resource blocks,
each group of the ninth number of groups of resource blocks includes an eleventh number of resource blocks and each group of the tenth number of groups of resource blocks includes a twelfth number of resource blocks, and
the ninth number, the tenth number, the eleventh number, and the twelfth number are calculated based on the seventh number and the eighth number;

transmit a first downlink control information (DCI) format comprising fifth information indicating a preemption indication, wherein
the second number of sets of bits in the fifth information have a one-to-one mapping with the second number of groups of symbols where the eighth number of bits in each set of bits have a one-to-one mapping with the eighth number of groups of resource blocks; and

assume, based on the transmission of the first DCI format, no uplink transmission on at least one corresponding group(s) of symbols and at least one corresponding group of resource blocks.

4. The base station apparatus according to the claim 3 , wherein
(the third number)=(the second number)−(the first number)+floor((the first number)/(the second number))·(the second number),

(the fourth number)=(the first number)−floor((the first number)/(the second number))·(the second number),

(the fifth number)=floor((the first number)/(the second number)),
(the sixth number)=ceiling((the first number)/(the second number)),
(the ninth number)=(the eighth number)−(the seventh number)+floor((the seventh number)/(the eighth number))·(the eighth number),

(the tenth number)=(the seventh number)−floor((the seventh number)/(the eighth number))·(the eighth number),

(the eleventh number)=floor((the seventh number)/(the eighth number)), and
(the twelfth number)=ceiling((the seventh number)/(the eighth number)).

5. A communication method of a user equipment (UE) that communicates with a base station apparatus, comprising:
receiving a radio resource control (RRC) message comprising first information used for indicating a first number of symbols and second information used for indicating a second number of groups of symbols, wherein
the second number of groups of symbols comprises a third number of groups of symbols and a fourth number of groups of symbols,
each group of the third number of groups of symbols includes a fifth number of symbols and each group of the fourth number of groups of symbols includes a sixth number of symbols, and
the third number, the fourth number, the fifth number, and the sixth number are calculated based on the first number and the second number;

receiving an RRC message comprising third information used for indicating a seventh number of resource blocks and fourth information used for indicating an eighth number of groups of resource blocks, wherein
the eighth number of groups of resource blocks comprises a ninth number of groups of resource blocks and a tenth number of groups of resource blocks,
each group of the ninth number of groups of resource blocks includes an eleventh number of resource blocks and each group of the tenth number of groups of resource blocks includes a twelfth number of resource blocks, and
the ninth number, the tenth number, the eleventh number, and the twelfth number are calculated based on the seventh number and the eighth number;

monitoring a first downlink control information (DCI) format comprising fifth information indicating a preemption indication, where
