A method determines a number of physical sidelink shared channel (PSSCH) symbols and a number of PSSCH demodulation reference signal (DMRS) symbols that will occur in a timeslot that is used for scheduling. PSSCH DMRS locations in the timeslot are derived based on applying the PSSCH DMRS symbols and the PSSCH DMRS symbols to a look-up table. A number of PSSCH DMRS resource elements (REs) is calculated based on the PSSCH DMRS locations and a scheduled number of PSSCH sub-channels. This number of PSSCH DMRS REs is used to determine a transport block size (TBS) included in transmissions over a sidelink channel.

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.

A user equipment (UE) is configured to receive message 3 (Msg3) transmissions. The UE receives a system information block (SIB) transmission from a base station of a wireless network, receives a downlink control information (DCI) transmission scheduling a message 2 (Msg2) transmission from the base station, receives the Msg2 transmission including an uplink (UL) grant for a message 3 (Msg3) initial transmission from the base station, determines the number of repetitions for the Msg3 initial transmission based on at least one of the SIB transmission, the DCI transmission, and the Msg2 transmission and determines a frequency hopping (FH) type and FH pattern based on at least one of the SIB transmission, the DCI transmission, and the Msg2 transmission.

Disclosed are methods and apparatus to process delay for PDCCH repetition. A transmission of a physical downlink control channel (PDCCH) repetition may be monitored. A multiplexing pattern of the PDCCH repetition and a physical downlink shared channel (PDSCH) within an overlapping symbol may be determined. A processing delay for a decoding of the PDCCH repetition, a decoding of the scheduled PDSCH, and an acknowledgement (ACK) preparation based on the multiplexing pattern of the PDCCH repetition and the PDSCH within the overlapping symbol may be determined. The PDSCH may be monitored after receiving the PDCCH repetition.

Method for processing delay for PDCCH repetitions

A UE may transmit a message comprising information regarding one or more physical random access channel (PRACH) capabilities of the UE to a base station (BS). The UE may then receive, from the BS, signaling comprising an indication of one or more configured PRACH formats supporting the one or more PRACH capabilities. Next, the UE may transmit, using the one or more configured PRACH formats, one or more preambles to the BS in a random access (RACH) procedure. Accordingly, the UE may receive a random access response (RAR) from the base station and further, in response to receiving the RAR, establish a connection with the BS.

Systems and methods used by reduced sensing user equipment (UE) (relative to a full sensing UE) are disclosed herein. A UE performing partial sensing may use knowledge of resource reservation periods for a resource pool of one or more resources to reduce sensing as compared to the full sensing case. A UE performing resource re-evaluation and/or resource pre-emption may use one or more sensing windows that are relatively smaller than windows used in the full sensing case to reduce sensing. A UE performing prioritized resource selection may use a sensing window to determine availability of resources within it prioritized resource selection window with a high reliability, thereby reducing the need to spend power on other sensing methods (which may include full sensing methods). Combinations of these embodiments are also contemplated.

Power saving sensing for reduced sensing UES using resource re-evaluation and resource pre-emption

Systems and methods for sidelink (SL) resource pool resource use by a user equipment (UE) are disclosed herein. In some embodiments, when the UE performs contiguous partial sensing in addition to periodic partial sensing, the UE performs one of resource selection and resource re-evaluation based a size of a time gap between a slot where the UE has SL data and a first slot of periodic-based candidate slots within a resource selection window. In other embodiments, the UE performs contiguous partial sensing without additional periodic partial sensing in the case where a packet delay budget (PDB) for the SL data is greater than a threshold. In some embodiments, the UE performs periodic partial sensing for resource re-evaluation and/or resource pre-emption according to a set of periodicity values P(and optionally period definition data K). Restrictions on the use of random resource selection by the UE are also described.

Procedures of sidelink resource pool resource use with reduced sensing

Some aspects of this disclosure relate to apparatuses and methods for implementing mechanisms for a network to use Doppler shift pre-compensation values for communicating Tracking Reference Signal (TRS) to a user equipment (UE) and for implementing mechanisms for triggering the UE to measure the Doppler shift pre-compensated TRS. Some aspects of this disclosure relate to a base station including a processor that determines a Doppler shift pre-compensation value associated with the UE in response to determining that the UE is moving with a speed greater than a threshold. The processor further generates an aperiodic Tracking Reference Signal (AP-TRS) or a semi persistent TRS (SP-TRS) for the UE. The AP-TRS or the SP-TRS is decoupled from a periodic TRS (P-TRS). The processor further transmits the AP-TRS or the SP-TRS to the UE. The AP-TRS or the SP-TRS can be used for time and frequency synchronization.

This disclosure relates to techniques for performing multi-transmission and reception point operation in a wireless communication system. A transmission control indication state may be indicated for future monitoring of a control channel, e.g., using dynamic signaling. The indicated state may be used to provide and receive control information for performing multi-transmission and reception point operation.

Some embodiments include an apparatus, method, and computer program product for enhanced Hybrid Automatic Repeat Request (HARQ)-ACK in a fifth generation (5G) wireless communications system. A user equipment (UE) can receive, during a HARQ-ACK window, a semi-persistent scheduling (SPS) Physical Downlink Shared Channel (PDSCH) transmission or a Physical Downlink Control Channel (PDCCH) transmission corresponding to a SPS PDSCH release. The UE can generate a Hybrid Automatic Repeat Request (HARQ)-ACK information bit corresponding to the reception. The UE can be configured with an offset value, k, and a length, l, of the HARQ-ACK window associated with an uplink transmission slot n, of a Physical Uplink Control Channel (PUCCH) transmission, and determine a starting slot of the HARQ-ACK window as n-k. When a corresponding valid uplink transmission slot is not available, the UE can transmit the HARQ-ACK information bit in the uplink transmission slot n of the PUCCH transmission.

Method for enhanced HARQ-ACK feedback in wireless communications

Approaches are described for receiving downlink signals simultaneously where analog beamforming is being used to increase the link budget between the base station and user equipment (UE). Alternatives within these approaches include the UE determining the synchronization signal block (SSB) to receive when there are multiple SSBs from different cells in a slot, and determining whether there are other signals in the same symbols with the selected SSB based on the type of signal and the SSB's functionality. In the case where there are another downlink signals channel state information-reference signal (CSI-RS) or physical downlink shared channel (PDSCH) from another cell, the UE selects the corresponding quasi co-location (QCL) assumption to receive the signals. Optionally, the UE can report whether it can support one or two QCL-TypeD at a time and whether it supports SSBs in different cells multiplexed in overlapped symbols.

Method for simultaneous reception of SSB and other signals

A method that determines a resource at a first user equipment (UE) for a sidelink communication from the second UE to a first UE is described. In an exemplary embodiment, the method receives a request from the second UE to send data to the first UE. In addition, the method determines a preconfigured resource selection window that is used by the second UE. Furthermore, the method determines a first sensing result at the first UE. The determined first sensing result includes information to be reported to the second UE for a resource selection. The determined first sensing results has a plurality of first sensing types. Further, the method transmits the first sensing result from the first UE to the second UE.

Methods and apparatus for sidelink resource exclusion for intra-device coordination in wireless communication

A user equipment (UE) may increase the reliability of transmission of a Physical Uplink Control Channel (PUCCH) by transmitting repeated copies of the PUCCH, according to a repetition pattern spanning one or more slots. In an intra-slot mode, more than one copy may be transmitted within each configured slot, with or without frequency hopping. The number of copies as well as a temporal gap between the transmission of successive copies may be configured by the network. The repetition pattern may or may not be interrupted by slot boundaries. In an inter-slot mode, one copy is transmitted per configured slot. Different copies may be transmitted in different directions, according to a spatial consistency pattern. The UE may perform repeated transmission of PUCCHs to different Transmission-Reception Points (TRPs) using respectively different timing advances and/or transmit power levels.
