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: Various embodiments provide techniques for channel state information reference signal (CSI-RS) transmission in a wireless cellular network. CSI-RS transmission bandwidth is determined based on a frequency domain allocation of a physical downlink shared channel (PDSCH), a physical uplink shared channel (PUSCH), or a physical downlink control channel (PDCCH). A user equipment (UE) receives the CSI-RS according to the frequency domain allocation and a time domain allocation.

Abstract: Disclosed embodiments are related to beam management in cellular communication networks, and in particular, provide a new tranmission (Tx) beamforming indication based on the flexible Tx beam-forming assignment on the corresponding reference signal configured in a transmission configuration indicator (TCI) state for downlink (DL) or spatial relation information in the uplink (UL). The Tx beam-forming on the reference signal of the TCI state configured for the DL physical channel/reference signal can be updated based on reported Tx beam in the UL or using UL measurements from Sounding Reference Signal (SRS) transmission. Similarly, spatial relation information configuration used to indicate Tx beam-forming in the UL, may be also updated based on the reference signal measurements in DL or by suing Downlink Control Information (DCI) based beam indication in a scheduling request indicator (SRI). Other embodiments may be described and/or claimed.

Abstract: Embodiments of a user equipment (UE) configured for operation in a fifth generation (5G) new radio (NR) network are disclosed herein. In some embodiments, a media access control Layer (MAC) control element (CE) (MAC CE) may activate a spatial relation info for a sounding reference signal (SRS) resource for two or more indicated component carriers (CCs). The spatial relation info for the SRS resource for the two or more indicated CCs may be applied in response to the activation. The SRS resource may be transmitted in the two or more indicated CCs with a same spatial transmission filter that is used for another reference signal configured in the spatial relation info when the UE is configured with one or more SRS resource configurations and when the spatial relation info is activated.

Abstract: 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.
