Abstract: systems and methods are disclosed for signaling for supporting joint and separate downlink/uplink transmission configuration indication (tci) operations. in one embodiment, a method performed by a user equipment (ue) comprises receiving a medium access control (mac) control element (ce) message from a network node and receiving a downlink control information (dci) from the network node comprising a tci field set to one of a plurality of tci field codepoints. the mac ce maps tci states to at least some of the tci field codepoints. the mac ce comprises a first field that indicates whether a first tci state indicated by the mac ce that is mapped to a first tci field codepoint in the dci is a downlink (dl) tci state or an uplink (ul) tci state and information that indicates whether a dl tci state, ul tci state, or both are indicated for the first tci field codepoint.

Abstract: disclosed is a method performed by a first radio unit, ru, () of a distributed base station system (), the first ru () comprising ni antennas (), the distributed base station system () further comprising a first aggregation unit, au, () connected to the first ru () via a first au fronthaul, fh, link () and a second ru () connected to the first au () via a second au fh link (), the second ru () comprising nantennas (), the distributed base station system () further comprising a bbu () connected to the first au () over a first bbu fh link (). the method comprises receiving, from a first number of ues (), uplink, ul, data streams comprising first user layers of the first number of ues (). the method further comprises obtaining a first channel estimate of a communication channel between the first number of ues () and the first ru (), determining first intermediate beamforming weights, bfw, sending, to the first au (), the first intermediate bfw and obtaining first part of bfw based on the first ul channel estimate. the method further comprises beamforming the received ul data streams based on the obtained first part of bfw into intermediately-beamformed ul data streams that are sent to the first au (), or receiving, from the first au (), first ru-adapted second part of bfw determined based on an inverse calculation of a combination of the first intermediate bfw and second intermediate bfw, determined by the second ru (), determining final bfw for the first ru based on the first part of bfw and the first ru-adapted second part of bfw, beamforming the ul data streams of the first user layers based on the determined final bfw for the first ru into completely beamformed ul data streams, and sending the completely beamformed ul data streams to the first au ().

Abstract: a wireless communication device () determines an idle bandwidth portion of a wireless channel. further, the wireless communication device () estimates one or more reception conditions at a further wireless communication device (). using a transmission bandwidth in the idle bandwidth portion of the wireless channel, the wireless communication device () sends a wireless data transmission to the further wireless communication device (). the transmission bandwidth of the wireless data transmission is selectively punctured based on the estimated one or more reception conditions.
