Abstract: A user equipment (UE) can include processing circuitry configured to decode synchronization information within a synchronization signal (SS) block, the SS block received within a SS burst set and occupying a subset of a plurality of Orthogonal Frequency Division Multiplexing (OFDM) symbols within a slot. At least one of the symbols in the subset coincides with a pre-defined symbol location associated with a demodulation reference signal (DM-RS) of a physical downlink shared channel (PDSCH). A synchronization procedure can be performed with a next generation Node-B (gNB) based on the synchronization information within the SS block. The DM-RS can be detected within the slot, where the DM-RS starts at a symbol location that is shifted from the pre-defined symbol location and following the subset of symbols. Downlink data received via the PDSCH is decoded based on the detected DM-RS.

Abstract: A network device (e.g., a user equipment (UE), or a new radio NB (gNB)) can process or generate a configuration of physical downlink control channel (PDCCH) monitoring in different search spaces sets independently from one another in order to manage different services optimally. A processor of the network device can be configured to receive physical downlink control channel (PDCCH) candidates of a PDCCH in a slot for channel estimation across search spaces of the slot. Different priorities can be determined among the PDCCH candidates in the slot based on a priority rule. Then a number of PDCCH candidates can be skipped/dropped from monitoring based on the different priorities of the PDCCH candidates to ensure that a threshold level of blind decoding operations across a plurality of slots of the PDCCH is being satisfied. The UE can monitor a portion of the PDCCH candidates while concurrently skipping another.

The UE receives a gNB control signal that contains an indication that the UE is able to operate as an initiating device and in response transmits a physical random access channel (PRACH) message within a Fixed Frame Period (FFP) of the UE. Transmission of the PRACH message is contingent on non-overlap of the PRACH message transmission with the idle period of a gNB FFP.

At least one of the symbols in the subset coincides with a pre-defined symbol location associated with a demodulation reference signal (DM-RS) of a PDSCH. The DM-RS can be detected within the slot, the DM-RS starting at a symbol location that is shifted from the pre-defined symbol location and following the subset of symbols. Downlink data scheduled by the PDCCH and received via the PDSCH can be decoded, where the decoding is based on the detected DM-RS.

Abstract: Systems and methods of reducing power consumption associated with paging or cDRX mode are described. A wake-up receiver (WUR) wakes up from an idle mode or cDRX state. Whether a wake-up signal (WUS) has been received by the WUR is determined. The WUS is a low-complexity signal that is less complicated than a PDCCH or PDSCH and is repeated multiple times at resource elements as indicated in a configuration from an eNB. If received, a baseband transceiver wakes up for reception of a PDCCH for the UE in a PO when the UE is in the idle mode or a PDSCH for the UE when the UE is in the cDRX state.

Abstract: Disclosed are systems and methods of selecting physical downlink control channel (PDCCH) candidates for non-coherent joint transmission (NC-JT) in a wireless network. For instance, first and second sets of ControlResourceSet and SearchSpace parameters can be configured for a UE. The first and second sets of ControlResourceSet and SearchSpace parameters are configured on a first downlink (DL) component carrier to enable NC-JT. A control channel element (CCE) limit can be determined for the first and second sets of ControlResourceSet and SearchSpace parameters. One or more PDCCH candidates can then be selected for the first and second sets of ControlResourceSet and SearchSpace parameters based at least in part on the determined CCE limits. NC-JT communication including at least a first communication from a first transmission and reception point (TRP), and a second communication from a second TRP can then be received.
