Abstract: User Equipment (UE) and methods for antenna port quasi co-location signaling in coordinated multi-point (CoMP) operations are generally described herein. In some embodiments, one or more downlink channels are at least partially offloaded from a serving Evolved Node-B (eNB) to one or more neighbor eNBs. The UE may receive signaling from the serving eNB to indicate a reference signal of a neighbor eNB to use for estimation of one or more large-scale physical-layer parameters associated with the one or more downlink channels provided by one of more of the neighbor eNB. The UE may estimate the one or more large-scale physical-layer parameters based on receipt of the indicated reference signal from the neighbor and serving eNBs. The UE may also apply the estimated one or more large-scale physical-layer parameters for processing the one or more downlink channels from the neighbor and serving eNBs.

Abstract: An apparatus and system are described for power control transmission for multiple physical random access channel (PRACH) transmissions. The systems include repetition level ramping for the PRACH transmissions, as well as power control mechanisms for PRACH transmissions that use identical transmission (Tx) beams and that use different Tx beams. The number of repetition attempts for a PRACH transmission increases when a random access response (RAR) is not received or does not pass contention resolution for a maximum number of attempts. A PRACH transmission within one or more transmission occasions is cancelled if the power exceeds a maximum power for PRACH transmissions.

Abstract: Systems for providing coverage enhancement for Msg 3 PUSCH and PUCCH carrying the HARQ-ACK for Msg4 of PRACH initial access are described. The gNB provides a 2-bit aggregation factor for transmission of the Msg3 PUSCH in an RAR UL grant field. The PUSCH frequency resource allocation field is limited to 12 bits so that the RAR has an overall number of bits that is the same as an RAR that does not contain the aggregation factor. A default PUSCH TDRA table includes a field to indicate a repetition level for Msg3 PUSCH transmission. For retransmissions, fields in DCI format 0_0 are repurposed to indicate an aggregation factor. Inter-slot frequency hopping may be configured by higher layers. Different PRACH resources are used to indicate UE coverage status.

Abstract: A user equipment (LTE) for operation in a fifth-generation system (5GS) is configured to decode configuration information for a first hybrid-automatic repeat request (HARQ) acknowledgement (ACK) (HARQ-ACK) codebook for first priority HARQ-ACK bits and for a second HARQ-ACK codebook for second priority HARQ-ACK bits. The configuration information may indicate a physical uplink control channel (PUCCH) resource for the first HARQ-ACK codebook and a PUCCH resource for the second HARQ-ACK codebook. The UE may multiplex the first priority HARQ-ACK bits and the second priority HARQ-ACK bits in a PUCCH transmission when the PUCCH resources for the first and the second HARQ-ACK codebooks overlap. The LTE may use the PUCCH resource for the higher priority HARQ-ACK bits to multiplex the first priority HARQ-ACK bits and the second priority HARQ-ACK bits.

Abstract: The disclosure describes mechanisms for reliability enhancement on control channel and data channel and mechanisms in URLLC. An apparatus of a RAN node for URLLC includes baseband circuitry to configure at least one DCI for scheduling transmission of at least one PDSCH content having same information. For each DCI, the baseband circuitry determines a CORESET for transmitting the DCI. The disclosure further describes mechanisms for the support of low latency transmission in URLLC. To improve peak data rate and spectrum efficiency in FDD system, the RAN node configures a DCI for scheduling data transmission using blank resources of a self-contained slot structure. Further, CBG-based transmission with separate HARQ-ACK feedback is provided to configure a DCI for scheduling data transmission of a TB and to divide the TB into multiple CBGs, and to configure uplink control data to carry separate HARQ feedback for the CBGs.

Abstract: A user equipment (UE) may communicate channel state information in a wireless network. The UE may include transceiver circuitry to receive orthogonal frequency division multiple access (OFDMA) signals from an Enhanced node B (eNB). The UE may include processing circuitry to derive one or more principal eigen beams from the received OFDMA signals. The principal eigen beams may have a rank greater than or equal to one. The processing circuitry may derive quantized eigen beams from the principal eigen beams. The processing circuitry may select, in response to the quantized eigen beams, a subset of available antenna ports on the eNB for receiving from the eNB and transmitting to the eNB. The UE may communicate to the eNB a bit pattern of the quantized eigen beams and at least one of a wideband channel quality indicator (CQI) or a subband CQI conditioned on the quantized eigen beams.

Abstract: Devices and methods of enhanced coverage (EC) paging are generally described. An evolved Node-B (eNB) may transmit multiple EC paging messages to user equipment (UE) over at least one paging cycle. Each EC paging message may contain the same paging information. The UE may combine the individual EC paging messages to achieve a predetermined link budget and subsequently may decode the EC combined paging message to determine whether the combined paging message is directed to the UE. The EC paging messages may contain information for more than one UE and a legacy P-RNTI or a specific P-RNTI for EC mode UEs. The EC paging messages may be transmitted in legacy occasions over several paging cycles or non-legacy paging occasions over one or more paging cycles. The EC paging messages may be transmitted in continuous or non-continuous subframes in a particular paging cycle.
