Additionally, embodiments provide techniques for repetition of a channel state information (CSI) report on a physical uplink shared channel (PUSCH) for coverage enhancement. Other embodiments may be described and claimed. ## Claims ### Claim 1 One or more non-transitory computer-readable media (NTCRM) having instructions, stored thereon, that when executed by one or more processors of a user equipment (UE) cause the UE to: receive configuration information to configure repetitions of a channel state information (CSI) report on a physical uplink shared channel (PUSCH), wherein the CSI report includes an aperiodic CSI (A-CSI) report or a semi-persistent CSI (SP-CSI) report; receive a downlink control information (DCI) to trigger the A-CSI report or activate the SP-CSI report; and encode, for transmission on the PUSCH, the CSI report with repetitions based on the configuration information and the DCI. ### Claim 2 (depends on 1) The one or more NTCRM of claim 1, wherein the configuration information indicates a number of the repetitions. ### Claim 3 (depends on 2) The one or more NTCRM of claim 2, wherein the number of repetitions is indicated separately from a number of repetitions of the PUSCH. ### Claim 4 (depends on 1) The one or more NTCRM of claim 1, wherein the configuration information is received via one or more of minimum system information (MSI), remaining minimum system information (RMSI), other system information (OSI), or dedicated radio resource control (RRC) signaling. ### Claim 5 (depends on 1) The one or more NTCRM of claim 1, wherein the configuration information is configured per DCI format. ### Claim 6 (depends on 1) The one or more NTCRM of claim 1, wherein the CSI report is the A-CSI report and is multiplexed on the PUSCH with a transport block, and wherein a number of the repetitions of the A-CSI is the same as a number of repetitions for the PUSCH. ### Claim 7 One or more non-transitory computer-readable media (NTCRM) having instructions, stored thereon, that when executed by one or more processors of a next generation Node B (gNB) cause the gNB to: encode, for transmission to a user equipment (UE), configuration information to configure repetitions of a channel state information (CSI) report on a physical uplink shared channel (PUSCH), wherein the CSI report includes an aperiodic CSI (A-CSI) report or a semi-persistent CSI (SP-CSI) report; encode, for transmission to the UE, a downlink control information (DCI) to trigger the A-CSI report or activate the SP-CSI report; and receive, from the UE on the PUSCH, the CSI report with repetitions based on the configuration information and the DCI. ### Claim 8 (depends on 7) The one or more NTCRM of claim 7, wherein the configuration information indicates a number of the repetitions. ### Claim 9 (depends on 8) The one or more NTCRM of claim 8, wherein the number of repetitions is indicated separately from a number of repetitions of the PUSCH. ### Claim 10 (depends on 7) The one or more NTCRM of claim 7, wherein the configuration information is transmitted via one or more of minimum system information (MSI), remaining minimum system information (RMSI), other system information (OSI), or dedicated radio resource control (RRC) signaling. ### Claim 11 (depends on 7) The one or more NTCRM of claim 7, wherein the configuration information is configured per DCI format. ### Claim 12 (depends on 7) The one or more NTCRM of claim 7, wherein the CSI report is the A-CSI report and is multiplexed on the PUSCH with a transport block, and wherein a number of the repetitions of the A-CSI is the same as a number of repetitions for the PUSCH. ### Claim 13 One or more non-transitory computer-readable media (NTCRM) having instructions, stored thereon, that when executed by one or more processors of a user equipment (UE) cause the UE to: receive, from a gNodeB (gNB), configuration information to indicate a repetition window for a physical random access channel (PRACH), wherein the repetition window includes a plurality of PRACH occasions; and encode a PRACH message for transmission with repetition in the respective PRACH occasions. ### Claim 14 (depends on 13) The one or more NTCRM of claim 13, wherein the configuration information indicates a starting position and a number of PRACH repetitions. ### Claim 15 (depends on 13) The one or more NTCRM of claim 13, wherein the configuration information is received via one or more of minimum system information (MSI), remaining minimum system information (RMSI), other system information (OSI), or dedicated radio resource control (RRC) signaling. ### Claim 16 (depends on 13) The one or more NTCRM of claim 13, wherein, to indicate the repetition window, the configuration information includes an offset and a periodicity, wherein the offset is a slot offset, a symbol offset, or a frame offset. ### Claim 17 (depends on 13) The one or more NTCRM of claim 13, wherein the configuration information includes an indication of whether the same beam or different beams are to be used for the repetitions of the PRACH message within the repetition window. ### Claim 18 (depends on 13) The one or more NTCRM of claim 13, wherein if the plurality of PRACH occasions in the repetition window associated with a same synchronization signal block (SSB) index are multiplexed in a frequency division multiplexing (FDM) manner, the PRACH message is transmitted in only one PRACH occasion of the repetition window. ### Claim 19 (depends on 13) The one or more NTCRM of claim 13, wherein the PRACH occasions for the repetitions are associated with a same synchronization signal block (SSB) for determination of transmit power, path loss, and reference signal received power. ### Claim 20 (depends on 13) The one or more NTCRM of claim 13, wherein the PRACH occasions for the repetitions are associated with different synchronization signal blocks (SSBs) for determination of transmit power, path loss, and reference signal received power.
