Abstract: Various embodiments herein provide techniques for minimum mean-square error interference rejection combining (MMSE-IRC) processing of a received signal, distributed between a baseband unit (BBU) and a remote radio unit (RRU). The RRU may perform a first phase of processing based on an extended channel that includes a channel of one or more user equipments (UEs) served by the RRU and interference samples that correspond to other cells or additive noise. The first phase may include scaling the interference samples by a scaling coefficient to obtain a modified extended channel, and performing maximum ratio combining (MRC) on the modified extended channel to obtain a processed signal. The RRU may send the processed signal to the BBU for the second phase of processing. The second phase of processing may include regularized zero forcing to remove interference. Other embodiments may be described and claimed.

Abstract: Apparatuses, systems, and methods for multiplexing of PUCCH for beam failure recovery and other signals. A UE may determine a transmission dropping rule and a transmission power scaling rule for a PUCCH which is dedicatedly configured for secondary BFR transmission, such as a PUCCH-BFR, when it is multiplexed with at least one other signal. The PUCCH-BFR and the at least one other signal may be multiplexed in a CC or in multiple CCs. The UE may determine a transmission dropping rule, e.g., so that UE can transmit an uplink signals with higher priority and drop the other uplink signal with lower priority to avoid beam collisions. The UE may determine a transmission power scaling rule, e.g., so the UE may scale transmission power within a CC and/or across CCs. The UE may multiplex the PUCCH-BFR with the at least one other signal according to the rules.

Abstract: Systems and methods for transmission of PDSCH and HARQ-ACK feedback in 5G networks are described. The TDRA of PDSCH repetitions are indicated in a DCI by a SLIV sequence configuration that contains multiple SLIV sequences. Each SLIV sequence for a slot is associated with an independent repetition factor and may also be associated with a partition factor to indicate a partition within the slot. One or more TRPs may be used to transmit each PDSCH repetition. The TCI states are mapped to the PDSCH repetitions in a round-robin fashion using an offset in terms of number of PDSCH repetitions from where TCI state switching starts and a number of consecutive PDSCH repetitions per TCI state. The HARQ-ACK bits in response to the PDSCH from the TRPs are concatenated in order of increasing control resource set higher layer signaling index.
