Abstract: Doppler pre-compensation is performed on synchronization signals using each of multiple Doppler pre-compensation patterns to generate a plurality of sets of Doppler pre-compensated synchronization signals that are transmitted using one or more beams. A signal indicating the Doppler pre-compensation patterns used is transmitted in one of a system information block (SIB) or a radio resource control (RRC) reconfiguration message, in connection with initial access by a user equipment (UE), idle UE cell reselection, connected UE data channel reception, or UE handover. The signal indicates Doppler pre-compensation patterns for a transmitting cell and Doppler pre-compensation patterns for one or more neighbor cells. The synchronization signal comprises a synchronization signal block (SSB) including a primary synchronization signal (PSS) and a secondary synchronization signal (SSS).

Abstract: A non-terrestrial network (NTN) node transmits configuration information including an indication of a maximum transmission block size (TBS) for a physical uplink shared channel (PUSCH) transmission or a physical downlink shared channel (PDSCH). A TBS for the PUSCH or PDSCH is determined based on at least the indicated TBS, and one of a signal indicates one of a maximum modulation and coding scheme (MCS) for the PUSCH or PDSCH transmission or whether the PUSCH or PDSCH transmission uses a default MCS, or the MCS is determined based on at least the indicated maximum MCS, and the PUSCH is transmitted or the PDSCH is received based on the determined TBS and the determined MCS. A maximum TBS, a maximum MCS, or a number of hybrid automatic repeat request (HARD) processes is indicated by a master information block (MIB), a system information block (SIB), or radio resource control (RRC) signaling.

Abstract: Methods and architectures to determine whether carrier aggregation (CA) component carrier signals transmitted or received by a user equipment (UE) device with a primary serving cell (PCell) and one or more secondary serving cells (SCell) exceed a maximum transmission timing difference compare a relative difference of signals derived from subframe boundaries, a subslot transmission time interval (sTTI) boundary or a combination thereof, with a maximum receive timing threshold value. In the uplink, timing advance groups (TAGs) for the PCell and/SCells may be compared by the UE to a maximum transmit timing threshold value. If the maximum thresholds are exceeded, the SCell may be dropped or changed to avoid UE from exceeding its power maximums.

Abstract: A synchronization signal block (SSB) including a primary synchronization signal (PSS), a secondary synchronization signal (SSS), a physical broadcast channel (PBCH) is transmitted using first and second beams. One or more symbols adjoining the first and second synchronization signals are configured to accommodate a beam switching time. At least one signal indicates a beam index for the first beam transmitting the first synchronization signal, and the beam index for the second beam transmitting the second synchronization signal is either signaled or determined based on a predetermined relationship between a resource for the first synchronization signal and a resource for the second synchronization signal. The beam indices may comprise first and second numbers of bits and/or may be jointly encoded. The beam indices may be indicated by one of the PSS, the SSS, the PBCH, a demodulation reference signal (DMRS), or a synchronization or reference signal designated for that purpose.

A connection setup completion message can be encoded for transmission to the BS using the uplink resource assignment. The set of PBCH symbols can include a set of four legacy PBCH symbols.

Abstract: Systems and methods provide solutions for testing an 8Rx capable UE using test cases for 4Rx capable UEs. An example method establishes a connection from a first Tx source and a second Tx source to each of 8Rx antenna ports. The connection duplicates a fading channel from both the first Tx source and the second Tx source to each of the eight Rx antenna ports, and adds independent noise for each of the 8Rx antenna ports. One test scenario uses 4Rx supported RF bands by connecting four of the Rx ports with data from a system simulator, and the other four Rx ports are connected with zero input. Same requirements specified with 4Rx capable UEs are applied. Another test scenario uses 8Rx supported RF bands and applies lower dB SNR requirements than those specified for 4Rx tests.

Abstract: Embodiments of a User Equipment (UE), Next Generation Node-B (gNB) and methods of communication are generally described herein. The UE receive training signals from a plurality of transmit-receive points (TRPs) associated with the gNB. Each training signal may comprise a reference signal resource identifier (ID) to indicate a corresponding TRP and a corresponding transmit direction of a plurality of transmit directions. The UE may, for each transmit direction of the plurality of transmit directions, determine an average signal quality measurement based on individual signal quality measurements in multiple receive directions. The UE may select, for reporting to the gNB, a subset of the average signal quality measurements to ensure that the average signal quality measurements excluded from the subset are less than or equal to a minimum value of the average signal quality measurements in the subset.

Abstract: Embodiments include apparatuses, methods, and systems that may decode system information by a UE in a wireless network to communicate with an eNB or a gNB. The apparatus may include a memory and processing circuitry coupled with the memory. The processing circuitry may identify a remaining time period of a current moment in a current time window, identify a decoding time interval for decoding system information based on a channel condition for a channel between the UE and the eNB or the gNB. Based on a first relationship between the decoding time interval and the remaining time period, the processing circuitry may store, or cause to store, in the memory one or more copies of the system information received during the decoding time interval; and may further decode, or cause to decode, the one or more copies of the system information. Other embodiments may also be described and claimed.
