Devices and methods for dynamic RACH

A wireless communication device in a wireless system may generate a High Efficiency Physical Layer Convergence Procedure (PLCP) Protocol Data Unit (HE PPDU) frame including (i) an Orthogonal Frequency Division Multiplexing (OFDM) symbol including padding bits and (ii) an extension having a non-zero signal strength, and transmit the HE PPDU frame. A High Efficiency signal (HE-SIG) field of the transmitted HE PPDU frame may include an indication for a duration of the extension to avoid ambiguity of the extension. A communication device in a wireless system may receive an HE PPDU frame including (i) an OFDM symbol including padding bits, and (ii) an extension having a non-zero signal strength, and transmit an Acknowledgement frame a predetermined inter-frame space after an end of the HE PPDU frame. An HE-SIG field of the received HE PPDU may include an indication for duration of the extension to avoid ambiguity of the extension.

The synchronization signal structure can include a sequence of Synchronization Signals (SS) including repetitions of a synchronization signal burst set. The synchronization signal burst set can include a plurality of synchronization signal bursts. The synchronization signal bursts can include a plurality of synchronization signal blocks, wherein the synchronization signal blocks can include a plurality of Synchronization Signals (SS).

Synchronization signal transmission techniques

Systems and methods of increasing paging opportunities when the unlicensed band is used are described. The gNB sends an RRC message that indicates multiple monitoring occasions in a paging occasion of a paging frame. The UE monitors a monitoring occasion of a PO to determine whether a PDCCH with a P-RNTI has been received in an unlicensed band. If such a PDCCH is received, the UE decodes PDSCH information in the PDCCH to determine whether the P-RNTI is a P-RNTI of the UE. If so, the UE avoids monitoring subsequent monitoring occasions of the PO. If the PDCCH does not contain a P-RNTI, the UE continues to monitor other monitoring occasions within the PO.

UE paging in NR unlicensed spectrum

A generation node B (gNB) for a fifth-generation (5G) new radio (NR) or a sixth-generation (6G) network is configured for slot-less operation at frequencies above a 52.6 GHz carrier frequency. The gNB may generate signalling to configure a user equipment (UE) with a gap between demodulation reference signal (DMRS) symbols for an associated physical downlink shared channel (PDSCH). The gNB may also encode the DMRS symbols for transmission in accordance with the gap and may encode the associated PDSCH for transmission during the gap between the DMRS symbol transmissions at symbol times following the DMRS symbols.

Generation node b (GNB) configured for slot-less operation at frequencies above a 52.6 GHz carrier frequency

Described is an apparatus of a User Equipment (UE) operable to communicate with a fifth-generation Evolved Node-B (gNB) on a wireless network. The apparatus may comprise a first circuitry and a second circuitry. The first circuitry may be operable to process a message comprising an indicator to indicate a number of contention based physical random access channel (PRACH) preambles within a PRACH occasion per Synchronization Signal Block (SSB). The second circuitry may be operable to generate a first PRACH occasion, based on the indicator.

Control resource set information in physical broadcast channel

A user equipment (UE) configured for operation in a sixth generation (6G) network may perform a random access channel (RACH) procedure with a generation node B (gNB). The UE may encode a physical random access channel (PRACH) preamble for transmission in a PRACH occasion (RO) For carrier frequencies above 52.6 GHz, the UE may determine a Radio Network Temporary Identifier (RNTI) (i.e., either a RA-RNTI or a MsgB-RNTI) based on an index of the PRACH occasion RO index. The UE may also decode a response from the gNB that includes the RNTI. The UE may determine the RNTI based on the RO index in a time domain and the RO index in a frequency domain.

Determination of RNTI for performing RACH procedure at carrier frequencies above 52.6 GHz

Communication in a wireless network using a phase-tracking reference signal (PT-RS) for orthogonal frequency division multiplexing (OFDM) includes determining one or more PT-RS groups of adjacent subcarriers in a resource allocation for a physical uplink shared channel (PUSCH) or a physical downlink shared channel (PDSCH), encoding data to be transmitted by the PUSCH or the PDSCH in data subcarriers within the resource allocation for the PUSCH or the PDSCH, and encoding phase-tracking reference signals within the one or more PT-RS groups of adjacent subcarriers.

Systems and methods of phase-tracking reference signal transmission for OFDM

Systems and methods for determining channel raster(s) and synchronization signal raster(s) for New Radio (NR) unlicensed spectrum are disclosed herein. For each of a plurality of data objects an NR channel raster position is determined using Absolute Radio Frequency Channel Number (NR-ARFCN) numbers. For each corresponding NR channel. Global Synchronization Channel Numbers (GSCNs), a number of Physical Resource Blocks (PRBs) based on channel subcarrier spacing (SCS). NR channel raster position placement, channel edges, synchronization signal and physical broadcast channel (SSB) edges, and an SSB raster position are calculated. The plurality of data objects may then be down selected based on e.g., corresponding Long Term Evolution (LTE) channel raster positions and/or entries of a second plurality of data objects calculated for NR channels that use a second SCS.

Channel raster and synchronization signal raster for NR unlicensed spectrum

A generation-Node B (gNB) configured for unlicensed spectrum operation above 52.6 GHz in a fifth-generation new-radio (NR) system (5GS) may encode a parameter (e.g., ssb-PositionsInBurst) for transmission to a UE (e.g., in the SIB1 or UE specific RRC signalling). The parameter may indicate candidate positions of synchronization signal blocks (SSBs) within a discovery reference signal (DRS) measurement timing configuration (DMTC) transmission window within slots of a system frame (SFN). During the DMTC window, the gNB may perform a LBT procedure on an unlicensed carrier of the unlicensed spectrum to determine if the unlicensed carrier is available. When the LBT is successful (i.e., the unlicensed carrier is available), the gNB may encode a discovery reference signal (DRS) for transmission on the unlicensed carrier. The DRS may include one or more of the SSBs transmitted during the candidate positions that fall within the DRS. The gNB may perform rate matching around the SSBs for a scheduled PDSCH based on the indicated parameter and transmit the rate-matched PDSCH.

PDSCH rate matching around SSB for NR unlicensed spectrum operation

A user equipment (UE) can include processing circuitry coupled to memory. To configure the UE for New Radio (NR) communications above a 52.6 GHz carrier frequency, the processing circuitry is to decode radio resource control (RRC) signaling to obtain a cyclic shift value in time domain. The cyclic shift value is associated with a demodulation reference signal (DM-RS) antenna port (AP) of a plurality of available DM-RS APs. A single carrier based waveform DM-RS sequence corresponding to the DM-RS AP is generated using a base sequence and the cyclic shift value. The single carrier based waveform DM-RS sequence is encoded with uplink data for transmission to a base station using a physical uplink shared channel (PUSCH) using a carrier above the 52.6 GHz carrier frequency.
