Abstract: A method and apparatus are described for a low cost machine-type-communication (LC-MTC) wireless transmit/receive unit (WTRU) to enhance coverage. An example method for physical broadcast channel (PBCH) enhancement includes receiving system information on an enhanced PBCH (ePBCH). The ePBCH is located in a set of radio frames which is a subset of available radio frames, where the subset includes fewer than all the available radio frames. The ePBCH is received in at least one radio frame of the set of radio frames. An example method for physical random access channel (PRACH) enhancement includes receiving configuration of legacy PRACH resources and enhanced PRACH (ePRACH) resources. The WTRU selects one of legacy PRACH resources or ePRACH resources based on a coverage capability. Another example method for PRACH enhancement includes receiving configuration of ePRACH resources. The ePRACH resources include multiple ePRACH resource types, each ePRACH resource type being associated with a coverage capability.

Abstract: Method, apparatus, and systems for flexible aperiodic reference signal (RS) transmissions are provided. For example, a method implemented in a wireless transmit/receive unit (WTRU) for wireless communications comprises receiving configuration information of one or more sounding reference signal (SRS) resource sets, each SRS resource set of the one or more SRS resource sets is associated with a slot offset and a set of slot offset deltas; receiving downlink control information (DCI) indicating an SRS request, the SRS request indicates an SRS resource set of the one or more SRS resource sets; determining an SRS configuration from a set of SRS configurations for SRS transmissions; determining a slot for transmitting an SRS based on the determined SRS configuration; and transmitting, in the determined slot, the SRS using resources of the indicated SRS resource set.

Abstract: A method and apparatus for receiving synchronization signal block (SSB) at a WTRU is disclosed. The WTRU receives a candidate SSB in a set of symbols in a slot. Then the WTRU receives an indication of a mode of association between candidate SSB positions and candidate SSB index. Next the WTRU determines a candidate SSB index associated with the candidate SSB. Then the WTRU determines a symbol number of a symbol in the set of symbols and a slot number of the slot based on the candidate SSB index and the indicated mode of association. And, then the WTRU receives a PDCCH transmission using a timing determined based on the determined symbol number and slot number. In some embodiments, the indicated mode of association may be either a first mode or a second mode.

Abstract: A method for transmitting system information on a PBCH is described herein. A transmission/reception point (TRP) may generate a concatenated master information block (MIB) transport block that includes information bits associated with system bandwidth information, timing information, system frame number (SFN), a beam sweeping configuration, and a control resource set (CORESET). The TRP may then attach at least 16 cyclic redundancy check (CRC) bits to the concatenated MIB and then prioritize the concatenated MIB and the at least 16 CRC bits based on content. The TRP may then perform channel coding of the prioritized concatenated MIB and the at least 16 CRC bits to produce coded bits using at least one polar encoder with a coding rate that is less than 1/3, perform rate matching via repetition on the coded bits, and then transmit the rate matched, coded bits on the PBCH of a radio frame.

Abstract: A wireless transmit receive unit (WTRU) may receive, via configuration information, at least one prohibition condition configured to prohibit GNSS activity. The GNSS activity may comprise at least one of GNSS acquisition, GNSS reporting, or GNSS assistance information (AI) reporting. The WTRU may identify a trigger related to the GNSS activity. The WTRU may determine whether a prohibition condition is activated. The prohibition condition may comprise a condition based on a prohibition timer, a condition based on GNSS validity duration, or a condition based on a characteristic of the WTRU. When the prohibition condition is determined to be active, the WTRU may perform the GNSS activity in response to an override or termination of the prohibition condition and based on the prohibition condition being determined to be active.

Abstract: The disclosed method and an apparatus are directed to determine an uplink transmission power in in New Radio (NR) systems by a wireless transmit/receive unit (WTRU) for transmitting at least one physical uplink shared channel (PUSCH), using multiple beams toward multiple Tx/Rx points (TRPs).

The method also includes determining beam-specific parameters like path loss for each beam, a configurable fractional power compensation factor for each beam, and a configurable maximum transmit power level of the each beam, wherein the fractional power compensation factor and the configurable maximum transmit power level for the each beam are determined dynamically or semi-statically based on at least deployment, WTRU mobility, or interference level. The method further includes transmitting at least one codeword to at least one receiving station using at least one of the multiple beams, which having a transmit power calculated based on the common parameters and the beam-specific parameters.
