Abstract: A method and a user equipment (UE) are provided for explicitly linking repeated physical downlink control channels (PDCCHs). The UE receives the repeated PDCCHs from a network. Each of the repeated PDCCHs include downlink control information (DCI) that schedules reception of a same physical downlink shared channel (PDSCH) at the UE. The UE links the repeated PDCCHs having common PDCCH candidate numbers across search space (SS) sets of a control resource set (CORESET). The repeated PDCCHs are received in accordance with the UE and the network communicating using a multi-transmission and reception point (TRP) repetition scheme or a multi-TRP multi-chance scheme.

Abstract: A method and a user equipment (UE) are provided for resource allocation. The UE receives repeated physical downlink control channels (PDCCHs) from a network. Each of the repeated PDCCHs includes downlink control information (DCI) that schedules reception of a same physical downlink shared channel (PDSCH) at the UE. The UE determines resources for at least one of transmission and reception at the UE, from a PDCCH having a latest start symbol or a latest ending symbol among the repeated PDCCHs. The repeated PDCCHs are received in accordance with the UE and the network communicating using a multi-transmission reception point (TRP) repetition scheme or a multi-TRP multi-chance scheme.

Abstract: A method and apparatus are provided for pre-emption, congestion control, and Tx/Rx alignment for use by a partial sensing UE. A method includes measuring resources within a first window; determining a number of the measured resources having an RSSI greater than a first threshold; determining a CBR based on the measured number of resources; and determining a CR limit based on the determined CBR and transmission priority. Determining the CBR based on the measured number of resources includes comparing a total number of measured resources within the first window to a second threshold; in response to the total number of measured resources being less than the second threshold, determining the CBR as a pre-configured CBR; and in response to the total number of measured resources being greater than or equal to the second threshold, determining the CBR based on a ratio of the number of the measured resources having the RSSI greater than the first threshold to the total number of measured resources within the first window.

Abstract: An apparatus and method are provided for partial transmission of a PDSCH DMRS due to PDSCH RM. The method includes determining, by the UE, whether a downlink received from a base station is rate matched; and in response to determining that the downlink is rate-matched, determining, by the UE, that a rate matching pattern of the downlink is applicable for partial transmission of a reference signal, and decoding, by the UE, the downlink with a partial transmission of the reference signal.

Abstract: A system and method for positioning in RRC Idle and Inactive states. In some embodiments, the method includes receiving, by a user equipment (UE), in Idle or Inactive state, a downlink positioning reference signal (PRS); transmitting, by the UE, in Idle or Inactive state, an uplink reference signal; and transmitting, by the UE, in Idle or Inactive state, a PUSCH carrying an estimate of the position of the UE. The uplink reference signal may be a positioning sounding reference signal (SRS), or a Physical Random Access Channel (PRACH) preamble with sequence length greater than 1151.

Abstract: A method for cross carrier scheduling can include: determining that a candidate DCI for a UE schedules a DG PDSCH that at least partially overlaps an SPS PDSCH for the UE, wherein the DCI is configured to be transmitted on a first CC having a first SCS, and the DG PDSCH is configured for transmission on a second CC having a second SCS different from the first SCS; determining a timing gap based on the smallest of the first SCS and the second SCS; determining that an available time between the scheduled SPS PDSCH and the DCI is equal to or greater than the timing gap; cancelling the SPS PDSCH responsive to determining that the available time between the scheduled SPS PDSCH and the DCI is equal to or greater than the timing gap; and transmitting the DCI to the UE.

Abstract: A method for performing an initial access process includes receiving, by a reduced capabilities (RedCap) user equipment (UE), a synchronization signal (SS)/physical broadcast channel (PBCH) block from a network. The SS/PBCH block may include a primary synchronization signal (PSS), a secondary synchronization signal (SSS), a first set of physical broadcast channels (PBCH), a second set of PBCH, and a third set of PBCH, wherein the third set of PBCH may be a duplicate of the second set of PBCH. The method may further include decoding, by the RedCap UE, the PSS, the SSS, the first set of PBCH, and the third set of PBCH.
