User equipments, base stations and methods for enhanced hybrid automatic repeat request processes

A user equipment (UE) that communicates with a base station apparatus, the UE comprising:

• receiving circuitry configured to receive a first radio resource control (RRC) configuration comprising first information used for configuring, for physical downlink shared channel (PDSCH) transmissions, a first number of consecutive slots across which a same symbol allocation is applied;
• and
• processing circuitry configured to determine, for the PDSCH transmissions, a number of consecutive slots across which a same symbol allocation is applied, wherein
• the receiving circuitry is configured to receive the PDSCH transmissions in consecutive slots the number of which is determined from i) the first number of consecutive slots and ii) a second number of consecutive slots across which a same symbol allocation is applied, and
• in a case that a) the receiving circuitry has received the first RRC configuration and a second RRC configuration comprising second information used for configuring, for the PDSCH transmissions, the second number of consecutive slots and b) the PDSCH transmissions are PDSCH transmissions scheduled without a corresponding PDCCH transmission using the second RRC configuration, the processing circuitry is configured to determine that the number of the consecutive slots is the second number of the consecutive slots.

A method performed by a user equipment (UE) that communicates with a base station apparatus, the method comprising:

• receiving a first radio resource control (RRC) configuration comprising first information used for configuring, for physical downlink shared channel (PDSCH) transmissions, a first number of consecutive slots across which a same symbol allocation is applied;
• determining, for the PDSCH transmissions, a number of consecutive slots across which a same symbol allocation is applied;
• and
• receiving the PDSCH transmissions in consecutive slots the number of which is determined from i) the first number of consecutive slots and ii) a second number of consecutive slots across which a same symbol allocation is applied, wherein
• in a case that a) the first RRC configuration and a second RRC configuration, which comprises second information used for configuring, for the PDSCH transmissions, the second number of consecutive slots, have been received and b) the PDSCH transmissions are PDSCH transmissions scheduled without a corresponding PDCCH transmission using the second RRC configuration, it is determined that the number of the consecutive slots is the second number of the consecutive slots.

A base station apparatus that communicates with a user equipment (UE), the base station apparatus comprising:

• transmitting circuitry configured to transmit a first radio resource control (RRC) configuration comprising first information used for configuring, for physical downlink shared channel (PDSCH) transmissions, a first number of consecutive slots across which a same symbol allocation is applied;
• and
• processing circuitry configured to determine, for the PDSCH transmissions, a number of consecutive slots across which a same symbol allocation is applied, wherein
• the transmitting circuitry is configured to perform the PDSCH transmissions in consecutive slots the number of which is determined from i) the first number of consecutive slots and ii) a second number of consecutive slots across which a same symbol allocation is applied, and
• in a case that a) the transmitting circuitry has transmitted the first RRC configuration and a second RRC configuration comprising second information used for configuring, for the PDSCH transmissions, the second number of consecutive slots and b) the PDSCH transmissions are PDSCH transmissions scheduled without a corresponding PDCCH transmission using the second RRC configuration, the processing circuitry is configured to determine that the number of the consecutive slots is the second number of the consecutive slots.
