Systems for performing radiation exposure monitoring that accommodate operating in multiple frequency bands are provided. A WTRU may be configured to monitor radiation exposure by determining an averaged power over an evaluation period. The radiation may be measured over a moving averaging window. The averaged measured power may be compared against SAR or MPE limits which may be defined in terms of normalized fractions or ratios in dB. The WTRU may be configured to measure for an averaged power periodically and/or in response to triggers.

Methods for performing discontinuous reception on sidelink

A wireless transmit/receive unit (WTRU) may receive, from a base station, a synchronization signal/physical broadcast channel (SS/PBCH) block transmission. The WTRU may transmit using a physical random access channel (PRACH) resource. Further, the PRACH resource may be determined based on an SS/PBCH block index. Also, the SS/PBCH block index may be determined based on information associated with the SS/PBCH block transmission. In a further example, the information associated with the PBCH block may be derived from a demodulation reference signal (DMRS) sequence. In another example, the DMRS sequence may be a PBCH DMRS sequence. Also, the information associated with the PBCH block may be derived from PBCH payload bits. Further, the SS/PBCH block index may be associated with a beam. In addition, SS/PBCH transmissions of different beams may be transmitted at different times. Further, the PRACH resource may include a preamble resource, a time resource and a frequency resource.

Methods, apparatus, systems and procedures to manage a multicast communication to a multicast group implemented by a respective wireless transmit/receive unit (WTRU) of WTRUs in the multicast group are disclosed. One representative method includes receiving, by the respective WTRU of the multicast group, a configuration, the configuration indicating a Random Access Channel (RACH) preamble to use for a negative acknowledgement (NACK) response to a multicast transmission to the respective WTRU, monitoring, by the respective WTRU, for data of the multicast transmission, determining, by the respective WTRU, whether the monitored for data was successfully received; and on condition that the monitored for data was not successfully received, sending, by the respective WTRU, the RACH preamble indicated by the received configuration.

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.

The WTRU may determine between a first type of waveform and a second type of waveform for the data transmission based on at least a format of the control information. Further, the WTRU may transmit the data transmission using the determined type of waveform. In an example, the type of waveform is further determined based on indication information included in the physical control channel transmission. Also, the first type of waveform may be an orthogonal frequency division multiplexing (OFDM) waveform and the second type of waveform is a discrete Fourier transform spread OFDM (DFT-S-OFDM) waveform. Moreover, the determination between the first type of waveform and the second type of waveform may be further based on an indication to use the DFT-S-OFDM waveform.

ePDCCH may be provided. For example, a WTRU may receive a configuration for monitoring an ePDCCH resource. Based on the configuration, the WTRU may be configured to monitor and may monitor the ePDCCH resource on a particular subframe. Additionally, a WTRU may derive an aggregation level for a subframe associated with an aggregation level number N. The WTRU may transmit or monitor an ePDCCH using the aggregation level associated with the Nfor the subframe. A WTRU may also receive a reference signal. The WTRU may then determine the type of reference signal received. The WTRU may perform a demodulation of the PDSCH or ePDCCH using a demodulation timing based on the determined type. The ePDCCH or PDSCH may also be monitored or received by identifying a demodulation reference timing implicitly based on a location of one or more ePDCCH resources where the WTRU may receive DCI.

A dynamic indication of reference signal functionality may be provided in a slot for an additional DM-RS. A configured CSI-RS/SRS may be dynamically indicated to use as an additional DM-RS in a slot. Frequency shift/hopping of DM-RS as a function of OFDM symbol and/or the order of OFDM symbol containing DM-RS may increase frequency density within a slot. DM-RS antenna port aggregation may increase DM-RS frequency density. One or more DM-RS antenna ports may be used to demodulate the same layer. PDCCH DMRS enhancement is provided. Frequency shift/hopping of PDCCH DMRS may be provided as a function of a REG index within an REG bundle, OFDM symbol index, etc. Use of multiple types of REG (e.g., low and high DM-RS) and REG type may be determined based on subcarrier spacing, operating frequency band, etc.

A wireless transmit receive unit (WTRU) may be configured to receive configuration information from a network regarding a set of spatial filters for the WTRU to use to communicate with the network. Each of the spatial filters may be associated a beam group and/or a measurement resource. The WTRU may further receive downlink control information (DCI) that indicates one or more time periods in which a portion of the set of configured spatial filters may be applicable. Based on the configuration information, the DCI, and/or a measurement, the WTRU may select a spatial filter from the portion of spatial filters to apply in the time period, and the WTRU may perform a communication task in the time period using the selected spatial filter.
