摘要： A user equipment (UE) is described. The UE includes receiving circuitry configured to receive a radio resource control (RRC) message comprising a first parameter(s) used for configuring a first allocation table and a second allocation table. Each of the first allocation table and the second allocation table are used for defining a time domain allocation for a physical uplink shared channel (PUSCH) transmission. The receiving circuitry is also configured to detect in a UE specific search space, a downlink control information (DCI) format comprising first information used for indicating a row index to the first allocation table or the second allocation table. The DCI format is used for scheduling of the PUSCH. The UE also includes transmitting circuitry configured to perform, based on a detection of the DCI format, the PUSCH transmission based on either of the first allocation table or the second allocation table.

摘要： An access node of a radio access network (RAN) that communicates over a radio interface with a wireless terminal. The access node comprises processor circuitry, transmitting circuitry, and receiving circuitry. The processor circuitry is configured to generate an indication of access node capability to support the wireless terminal when the wireless terminal operates in a restricted mode. The transmitting circuitry is configured to transmit the indication to the wireless terminal. The receiving circuitry is configured to receive an indication from the wireless terminal that the wireless terminal is in the restricted mode. The processor circuitry is further configured to make a determination, upon receipt of the indication from the wireless terminal, that a connection with the wireless terminal can be maintained in the restricted mode and to generate a responsive message based on the determination.

摘要： A user equipment (UE) is described. The UE includes a processor and memory in electronic communication with the processor. Instructions stored in the memory are executable to determine a HARQ-ACK codebook size for multiple slots on a single carrier (CC) or one or more slots on multiple carriers. The instructions are also executable to send a single HARQ-ACK report for the multiple slots based on the HARQ-ACK codebook size.

摘要： A user equipment (UE) is described. The UE includes receiving circuitry configured to receive a radio resource control message including first information used for configuring a number of more than one code block groups (CBGs) in a transport block (TB). The receiving circuitry is also configured to receive the more than one CBGs, the more than one CBGs comprising first CBGs and second CBGs. The UE also includes processing circuitry configured to determine a number of code blocks (CBs) from the TB. A first number, a second number, a third number, and a fourth number are given based on the number of more than one CBGs and the number of CBs. The first number is a number of the first CBG(s). The second number is a number of CB(s) comprised of each of the first CBG(s). The third number is a number of the second CBG(s). The fourth number is a number of CB(s) comprised of each of the second CBG(s).

摘要： A method includes configuring, by a base station, at least one of: a first timing indicator indicating a first delay between a downlink (DL) grant for a codeblock group (CBG)-based transmission and the CBG-based transmission; a second timing indicator indicating a second delay between the CBG-based transmission and a hybrid automatic repeat request acknowledgement (HARQ-ACK) for the CBG-based transmission; and a third timing indicator indicating a third delay between the CBG-based transmission and another DL grant for a pre-Acknowledgement/Non-Acknowledgement (pre-A/N) retransmission of the CBG. The method also includes transmitting, by the base station, a scheduling downlink control information (DCI) over a physical downlink control channel (PDCCH), the scheduling DCI comprising at least one of the first, second, and third timing indicators.

摘要： A user equipment (UE) receives, from a base station apparatus (gNB), a radio resource control message including information used for configuring whether a first reference signal is used for uplink transmissions or a second reference signal is used for uplink transmissions. The first reference signal is a demodulation reference signal associated with a physical uplink shared channel. The second reference signal is a demodulation reference signal associated with a physical uplink shared channel. The UE also transmits, based on the information, to the gNB, the first reference signal on an antenna port. The UE transmits, based on the information, to the gNB, the second reference signal on the same antenna port as the antenna port on which the first reference signal is transmitted. The second reference signal is mapped to resource elements in a resource block, which are different from resource elements in a resource block to which the first reference signal is mapped.

摘要： A UE is described that communicates with a base station apparatus on serving cells having a primary cell and one or more secondary cells. The UE includes receiving circuitry configured to receive, a RRC message including first information configuring a CGB based transmission for a PDSCH. The receiving circuitry is also configured to receive, a RRC message including second information configuring a maximum number of CBGs per transport block. The UE includes processing circuitry configured to determine the number of bits for CBG transmission information comprised in a first DCI format, wherein the first DCI format is used for scheduling of the PDSCH. In a case that the first information is configured, the number of bits for the CBG transmission information comprised in the first DCI format may be determined based on the second information.
