    摘要: A method and apparatus provide for receiving a configuration of a plurality of transmission configuration indicator states for a serving cell for physical downlink shared channel transmissions, wherein each of the plurality of transmission configuration indicator states contains parameters for configuring a quasi-co-location relationship between downlink reference signals and demodulation reference signal ports of the physical downlink shared channel transmissions. A physical downlink control channel is received, which includes downlink control information for scheduling a physical downlink shared channel. A determination is made as to whether an offset between the reception of the physical downlink control channel and a reception of the physical downlink shared channel is less than a predetermined threshold, where in response to the determination that the offset is less than the predetermined threshold, a configured pair of transmission configuration indicator states comprising a first transmission configuration indicator state and a second transmission configuration indicator state is selected from the received configuration of the plurality of transmission configuration indicator states. The physical downlink shared channel is decoded based on the selected configured pair of transmission configuration indicator states.

    摘要: A first indication that indicates a time frequency region can be received. A second indication indicating the priority of an uplink transmission in a set of time frequency resources as a high priority uplink transmission can be received. Whether at least a portion of the set of time frequency resources of the high priority uplink transmission overlaps with the indicated time frequency region can be determined. Whether to transmit the high priority uplink transmission if at least the portion of the set of time frequency resources of the high priority uplink transmission overlaps with the indicated time frequency region can be determined. The high priority uplink transmission can be transmitted based on determining whether to transmit the high priority uplink transmission.

    摘要: Apparatuses, methods, and systems are disclosed for synchronization signal block selection. One method includes receiving multiple synchronization signal blocks on a first wideband carrier. Each synchronization signal block includes at least one synchronization signal and a physical broadcast channel. The method includes detecting at least one synchronization signal block of the synchronization signal blocks, determining at least one synchronization signal frequency associated with the at least one detected synchronization signal block, and selecting a first synchronization signal block of the at least one detected synchronization signal block and a first synchronization signal frequency of the at least one synchronization signal frequency. The first synchronization signal block is associated with the first synchronization signal frequency. The method includes decoding a first physical broadcast channel of the first synchronization signal block, and determining whether to reselect the first synchronization signal block based on a result of decoding the first physical broadcast channel.

    摘要: Apparatuses, methods, and systems are disclosed for downlink assignments for downlink control channels. One method includes, in response to an assignment group comprising a first assignment: determining a first data channel allocation comprising resources allocated to a first data channel; determining a first DMRS symbol location associated with the first data channel based on the first assignment, a first set of OFDM symbols, and a second set of OFDM symbols; and decoding the first data channel. The method includes, in response to the assignment group comprising a second assignment: determining a second data channel allocation comprising resources allocated to a second data channel; determining a second DMRS symbol location associated with the second data channel based on the second assignment, the first set of OFDM symbols, and the second set of OFDM; and decoding the second data channel.

    摘要: Apparatuses, methods, and systems are disclosed for uplink transmission power allocation. One method includes: determining a transmission time for a first transmission (“FT”); determining first transmissions overlapping with the FT that start before a start time (“ST”) of the FT; determining a cut-off time (“COT”) for power determination; determining second transmissions overlapping with the FT that start at or later than (“SAOLT”) the ST; scheduling information and/or transmission information for the second transmissions is known at or before the COT; determining third transmissions that overlap with the FT that SAOLT the ST; scheduling information and/or transmission information for the third transmissions is known after the COT; allocating FT power based on a maximum total transmission power for the first transmissions and a minimum guaranteed power corresponding to the second transmissions and/or the third transmissions; and performing the FT using the FT power.

    摘要: Apparatuses, methods, and systems are disclosed for efficient RACH behavior. One apparatus includes a transmitter that transmits a first PRACH preamble to a base unit to start a RACH procedure; a receiver that receives a RAR (Msg2) from the base unit during a random access response window; and a processor that controls the transmitter to transmit a second PRACH preamble in response to being unable to transmit a RACH Msg3 within an indicated transmission opportunity. The processor may obtain multiple transmission opportunities for transmitting a RACH message such as RACH Msg1 or RACH Msg3 or monitor for multiple RACH Msg2 where transmission opportunity data are conveyed via a RACH Order, an RAR, or DCI for the RACH message. A method or system may perform functions of the apparatus.
