Abstract: This disclosure relates to techniques for signaling a quasi-colocation (QCL) update in a wireless communication system. A network or base station may indicate to a UE to change a spatial relationship for transmission/reception. The base station may provide aperiodic reference signals for the UE to use in beam tracking according to the new spatial relationship. Optionally, the base station may also provide aperiodic reference signals for time, frequency, and/or phase tracking. Thus, the network may configure the UE to change to the new spatial relationship and use the aperiodic reference signals to quickly complete initial tracking operations.

Abstract: Apparatus and methods are provided to enhance communications for NTN. In some aspects, a base station (BS) comprises a processor configured to schedule an uplink transmission in response to an uplink transmission request from a user equipment (UE) using one or more subframes ranging from a first uplink subframe to a last uplink subframe. The processor is further configured to determine or receive a timing advance (TA) indicating amount of subframes transmitted during a time delay between the UE and the BS and schedule a downlink transmission aligned with the uplink transmission. The downlink transmission is blocked from subframes ranging from TA plus one or more subframes ahead of the first uplink subframe to TA minus one or more subframes ahead of the last uplink subframe. The processor is further configured to transmit and receive, via a non-terrestrial equipment, the uplink and the downlink.

Abstract: This disclosure relates to techniques for performing multi-transmission and reception point operation in a wireless communication system. A plurality of transmission control indication states may be indicated for future use, e.g., using one or more lists. A subset of the indicated states may be activated and the subset may be greater than 8 states. One or more states of the subset may be used for performing multi-transmission and reception point operation in a single downlink control information mode.

Abstract: A user equipment (UE) includes a transceiver and a processor that is configured to identify a plurality of flows corresponding to data to be sent in an uplink (UL) direction. The processor is also configured to map a subset of the plurality of flows to a logical channel (LCH) of a plurality of LCHs. The processor is further configured to multiplex two or more scheduling requests (SRs) into an integrated SR for requesting one or more physical uplink control channel (PUCCH) resources corresponding to each flow of the subset of the plurality of flows of at least one LCH of the plurality of LCHs. Each SR included in the integrated SR corresponds to an SR for the data associated with at least one flow of the subset of the plurality of flows.

Abstract: A cell performs beam management operations for a user equipment (UE). The cell transmits a first group of multiple reference signals via a first transmission reception point (TRP) to a user equipment (UE), transmits a second group of multiple reference signals via a second different TRP to the UE, receives an indication that the UE has selected a first beam associated with one of the multiple reference signals of the first group and a second beam associated with one of the multiple reference signals of the second group and transmits downlink data to the UE using the first beam and the second beam.

Abstract: A cellular base station (BS) which transmits more flexible downlink control information (DCI) to the UE, and a UE capable of receiving and processing a received DCI message. The DCI message may have a DCI format of 0_1 or 0_2 and further may comprise an UL-SCH set to 0, a CSI request field of all 0s and an SRS request field having a nonzero value. The DCI message may indicate to the UE that the UE should: 1) transmit an aperiodic SRS corresponding to SRS request; and 2) that the UE should not transmit on the PUSCH. The DCI may include existing fields that specify either a slot offset or beam information useable when transmitting the aperiodic SRS. The base station may also generate a DCI message with an SRS trigger that is targeted to a plurality of UEs in a group, or a plurality of groups of UEs, for greater efficiency.

Abstract: Techniques are disclosed herein for single downlink control information based simultaneous physical uplink control channel transmission over multi-panel. An example embodiment can include a user equipment (UE) configured to receive a first indication as to a multi-panel simultaneous transmission scheme for simultaneous transmission of a physical uplink control channel (PUCCH) transmission in the frequency domain (FD) based on a radio resource control (RRC) transmission, the PUCCH transmission including a first PUCCH transmission through a first panel over a first FD part and a second PUCCH transmission through a second panel over a second FD part. The UE can transmit the first PUCCH transmission through first panel over the first FD part via the multi-panel simultaneous transmission scheme. The UE can further simultaneously transmit the second PUCCH transmission through the second panel over the second FD part via the multi-panel simultaneous transmission scheme.
