Abstract: Methods, apparatuses, and systems are disclosed for enhancing timing relationships in non-terrestrial networks (NTNs), e.g., by managing timing offset values and intelligently handling reporting failure relating to timing information reporting. To accommodate increased propagation delay in NTNs, a user equipment (UE) may supplement its timing advance (TA) value with component values representing roundtrip times to the satellite. The UE may maintain both open-loop and closed-loop portions of the TA value, and may report the TA value, or components thereof, to the network for timing synchronization. Methods and systems are also disclosed for failure handling in this reporting process.

Abstract: A method performed by a STA may comprise receiving data of a MU-HE-PPDU, from an AP. The MU-HE-PPDU may comprise a HE-SIG-A field, a first HE-SIG-B portion and a second HE-SIG-B portion. The first HE-SIG-B portion may be received on a first channel and the second HE-SIG-B portion may be received on a second channel which is different than the first channel. The first HE-SIG-B portion may include one or more STA identifiers.

Abstract: Methods and apparatus are described herein for dynamic allocation of multiple channels and data streams for multi-channel transmission and multiple-input and multiple-output (MIMO). For example, a station (STA) may receive an enhanced poll (EPoll) frame that includes a time offset, a channel offset and antenna/sector settings from an access point (AP). The STA may transmit, based on the received EPoll frame, an enhanced service period request (ESPR) frame that includes a MIMO control field and a multi-channel control field. The MIMO control field may indicate whether the STA supports MIMO transmission. The multi-channel control field may indicate whether the STA supports multi-channel transmission. Upon transmitting the ESPR frame, the STA may receive an enhanced grant frame from the AP. The enhanced grant frame may include an antenna configuration and a multi-channel allocation to enable the STA to perform the MIMO transmission and the multi-channel transmission.

Abstract: A user equipment (UE) may monitor a downlink frequency position to detect a synchronization block (SSB) from a cellular base station. When monitoring the downlink frequency position, the UE may be configured to use at least one step size in calculating a SSB frequency position. The UE may determine a subcarrier spacing (SCS) used by the cellular base station in response to monitoring the downlink frequency position, and the subcarrier spacing for one or more SSB transmissions may be determined at least in part based on the step size used in calculating the SSB frequency position. The UE may then utilize the determined subcarrier spacing of the one or more SSB transmissions in communicating with the cellular base station.

Abstract: A base station may establish a cellular link with a user equipment (UE) according to a single frequency network scheme. The base station may then determine one or more control resource set (CORESET) transmission configuration indication (TCI) states and transmit signaling to configure the UE with the one or more CORESET TCI states. Additionally or alternatively, the one or more CORESET TCI states may be useable by the UE in performing communications with at least one of a first transmission reception point (TRP) and a second TRP associated with the cellular link with the cellular network.

Abstract: Methods to enhance the coverage of NR systems for coverage-limited wireless devices are disclosed. A serving base station may configure a coverage-limited UE with parameters for the UE to operate in a coverage enhancement mode through RRC signaling, DCI, or RAR grant. The UE may use the configuration parameters to determine whether to enter into the coverage enhancement mode when connecting and communicating with the serving base station. The configuration parameters may configure the UE to exploit both time diversity and frequency diversity to extend and enhance coverage when receiving PDSCH and PDCCH channels. The UE may use the configuration parameters to receive PDSCH and PCCCH that are coverage enhanced using time repetitions and frequency hopping. Advantageously, the base station may flexibly and dynamically configure the UE with coverage enhancement parameters to extend the coverage of the UE using time diversity and frequency diversity gains as the UE moves around.

Abstract: Systems and methods for multidimensional beam refinement procedures and signaling for millimeter wave WLANs. In some embodiments, there are multi-dimensional enhanced beam refinement protocol MAC and PHY frame designs that extend the MAC packet and the PPDU format with or without backwards compatibility. The multiple dimensions may be supported jointly or separately. In other embodiments, the increased data signaled in the eBRP frame designs may be more efficiently signaled with reduced BRP frame sizes, such as through a training type dependent BRP minimum duration selection procedure or use of null data packet BRP frames. In further embodiments, the maximum duration of the interframe spacing between BPR packets may be varied to improve the efficiency of BRP operation.

Abstract: A wireless transmit receive unit (WTRU) may be configured to transmit uplink control information such as Hybrid Automatic Retransmission Request (HARQ) Acknowledgement or Negative Acknowledgement (ACK/NACK) using a sequence. The HARQ ACK/NACK may comprise one bit or two bits of information, and the WTRU may use a cyclic shift of the sequence to transmit the HARQ ACK/NACK. The WTRU may use different cyclic shifts of the sequence to transmit different HARQ ACK/NACK values and the cyclic shifts may be separated from each other in a manner to facilitate the transmissions. The WTRU may be further configured to receive, from a physical downlink control channel (PDCCH), an indication of a resource block for transmitting the HARQ ACK/NACK.
