Abstract: Method and apparatus for a WTRU to harvest energy from uplink signals of other WTRUs in a wireless network are disclosed. In an example, a method includes sending WTRU location information and determining a mapping between one or more geographical areas and their respective unique geographical radio network temporary identifier (RNTI) (geo-RNTI) and determining a current geo-RNTI of the WTRU based on the WTRU location information. The method may include decoding one or more configuration parameters of a first group of one or more other WTRU in the determined geo-RNTI, switching receive circuitry of the WTRU based on the one or more configuration parameters decoded; and harvesting radio frequency (RF) energy from uplink transmissions of the one or more other WTRUs based on switching of the receive circuitry.

Abstract: A wireless transmit/receive unit, WTRU, may include an Energy Harvesting device, EH, a Zero Energy transceiver, ZE, and a main transceiver. The WTRU may initialize operation using the main transceiver, and receive beam detection configuration and mapping information. The WTRU may initialize beam (re-) selection procedure using the ZE transceiver, and use the received beam detection configuration to determine detectable beam IDs. and use the received mapping information to retrieve EH signaling configuration. The WTRU determines expected EH performance for each detected beam, and selects the beam with best expected EH performance. On condition that the WTRU determines necessity of dynamic EH signaling for the selected beam, it proceeds with presence declaration procedure to request optimized dynamic EH signaling. The WTRU utilizes control signaling channel parameters to dynamically receive optimized EH signal configuration, and configures its EH circuitry, and harvests energy.

Abstract: A method performed by a base station may compromise: detecting an interference pattern; determining that the interference pattern impacts one or more code blocks (CBs) within one or more code block groups (CBGs); adjusting a size of the one or more CBGs; and transmitting, to a wireless transmit/receive unit (WTRU), information associated with the adjusting of the size of the one or more CBGs. The interference pattern may be caused by a radio detection and ranging (RADAR) system. The adjusting of the size of the one or more CBGs may compromise increasing or decreasing the number of CBs within the one or more CBGs. The transmitting of the information relating to the adjusting of the size of the one or more CBGs may be performed via master information block (MIB) signaling, radio resource control (RRC) signaling, or downlink control information (DCI) signaling.

Abstract: A method implemented in a wireless transmit/receive unit (WTRU) for wireless communications includes receiving a signal sequence from a base station (BS) and generating a channel quality indicator (CQI) indication based on the signal, transmitting the CQI indication to the BS, receiving a first control message from the BS comprising configuration information, wherein the configuration information includes information elements for configuring CQI subgroups, determining a CQI subgroup identifier (ID) based on the information elements included in the received first control message, and transmitting an energy harvesting feedback using at least one resource associated with the CQI subgroup ID.

Abstract: A base transmission signal and an auxiliary transmission signal may be used to (e.g., concurrently) improve a harvesting efficiency of an energy receiver while maintaining a prespecified performance level of an information receiver. An auxiliary transmission signal may be constructed. The construction of the auxiliary transmission signal may be signaled. An auxiliary transmission signal may be adapted. The adaptation of the auxiliary transmission signal may be signaled. An impact of auxiliary transmission signals on an information receiver's performance may be mitigated. One or more narrowband energy harvesting (EH) signals may be used, for example to provide a high peak to average power ratio (PARR) for EH devices (e.g., without significantly impacting overall transmitted signal PARR) characteristics. One or more narrowband auxiliary signals may be used, for example to enhance the PARR characteristics of an information signal sub-band.

Abstract: A method for initial timing synchronization for a WTRU to communicate with a network includes receiving an in-channel narrowband synchronization sequence from the network to enable initial coarse timing synchronization, determining coarse timing offset and a range between a beam source of a network transmitter and the WTRU, selecting a wideband sequence for fine timing synchronization using the estimated range, transmitting the selected wideband sequence for fine timing synchronization during an uplink timing occasion, receiving from the network a transmission of the selected wideband sequence for fine timing synchronization, and establishing fine timing synchronization between the WTRU and the network using the selected sequence.
