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.

Abstract: Systems, methods, and circuitries are provided for maximizing use of discovery reference (DRS) resources for remaining minimum system information (RMSI) allocation. An example method includes configuring Type 0 physical downlink control channel (PDCCH) CORESET monitoring to include monitoring in either a first slot or a first slot and a second slot; generating a synchronization signal block (SSB) encoding the configured PDCCH CORESET monitoring; and transmitting the SSB to a user equipment (UE) by way of a discovery reference signal (DRS).

Abstract: Systems, methods, and baseband processors are provided to generate or process symbols in a synchronization subframe. In one example, a method includes selecting non-consecutive orthogonal frequency division multiplexing (OFDM) symbols in a synchronization subframe. A transmitter is instructed to transmit demodulation reference symbols (DM-RS) on identical first sets of subcarriers in respective OFDM symbols of the selected non-consecutive OFDM symbols for a Physical Broadcast Channel (PBCH) using a same transmit beam, wherein a gap between two subcarriers in a respective set of the identical first sets of subcarriers is three subcarriers. The transmitter is instructed to transmit the PBCH on identical second sets of subcarriers in respective OFDM symbols in the selected non-consecutive OFDM symbols.

Abstract: Devices and methods of receiving a PDCCH-less xSIB are generally described. A UE receive a xPBCH that occurs in a 0th or a 25th subframe and an ePBCH in an ePBCH transmission block. The ePBCH has the xSIB and is received on different Tx beams. The ePBCH spans consecutive symbols on the same subcarrier and with the same ePBCH symbol. The frame number, subframe number and symbol number of the ePBCH is dependent on a subframe number and symbol number of the xPBCH. The number of beams received for a particular symbol is dependent on a total number of beams, a beam sweeping time for the beams and a transmission periodicity of the xPBCH and ePBCH. The UE also uses different OCCs to demodulate a DMRS from different APs, in a same PRB as the ePBCH.

Abstract: The first circuitry may be operable to establish a first UE Receive (Rx) beam as being for reception of data from a first eNB. The second circuitry may be operable to process a transmission including Downlink Control Information (DCI), wherein the DCI carries an eNB cell-switching indicator. The first circuitry may also be operable to establish a second UE Rx beam as being for reception of data from a second eNB based on the eNB cell-switching indicator.

Abstract: Systems, devices, and techniques for adjusting a user equipment (UE) processing time parameter in a wireless communication system that include transmission and reception points (TRPs) are described. A described technique performed by UE includes receiving a first physical downlink shared channel (PDSCH) from a first TRP corresponding to a first scheduling physical downlink control channel (PDCCH) and a second PDSCH from a second TRP corresponding to a second scheduling PDCCH. The technique further includes transmitting a first hybrid automatic repeat request acknowledgement (HARQ-ACK) message and a second HARQ-ACK message based on the first PDSCH and the second PDSCH in accordance with a first processing time parameter and a second processing time parameter, respectively. The first processing time parameter can be based on a PDSCH mapping type, a processing capability of the UE, and one or more timing characteristics of the first PDSCH and the second PDSCH.

Abstract: An approach is described for an access node configured for ultra-reliable and low latency (URLLC) transmission using multi-transmission reception point (TRP) to a UE. The access node includes processor circuitry and radio front end circuitry. The processor circuitry is configured to allocate resource blocks into a first portion and a second portion based on a resource indication value (RIV), a length of contiguously allocated resource blocks (LRBS) and a fraction. The radio front end circuitry is configured to transmit the first portion to the UE via a first transmission reception point (TRP1), and transmit the second portion to the UE via a second transmission reception point (TRP2).
