Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a base station may receive, from a user equipment and at a physical layer entity of the base station, channel state information (CSI) that includes a CSI part 1 and a CSI part 2, the CSI part 1 having a length known to the base station and the CSI part 2 having a length that is based at least in part on a payload of the CSI part 1. The base station may decode, at the physical layer entity of the base station, a payload of the CSI part 2 based at least in part on a payload of the CSI part 1 and one or more parameters indicated by a medium access control (MAC) layer entity of the base station. Numerous other aspects are described.

Abstract: In an aspect, an O-DU transmits a C-Plane message including a section description that specifies common PRB information associated with a plurality of RSs, the section description comprising a set of RS-specific section description extensions that each specify a PRB offset and a modulation scaling factor for a respective RS among the plurality of RSs. The O-RU processes the C-Plane message with modulation compression in accordance with the set of RS-specific section description extensions. In another aspect, a first O-RAN unit (e.g., O-DU or O-RU) transmits a message to a second O-RAN unit (e.g., O-RU or O-DU) associated with combining across symbols at an O-RU.

Abstract: The apparatus sends a request from a medium access control (MAC) layer to at least one of a Physical (PHY) Layer or a radio frequency (RF) component using an application protocol interface (API) and receives a response message from the at least one of the PHY layer or the RF component comprising an hierarchical indication of at least one capability of the PHY layer or the RF component using the API. The apparatus may also configure the PHY layer or the RF component based on the at least one capability.

Abstract: Methods, systems, and devices for wireless communication are described. A first device in a synchronous network performs a first clear channel assessment (CCA) procedure on a channel; identifies the channel as being available based at least in part on the first CCA procedure; and transmits a packet on the channel immediately following the completion of the first CCA procedure. A second device performs a CCA procedure on the channel using the same count-down duration if the first and second devices are associated with the same first operator. If the first and second devices are associated with different operators, the second device performs a second CCA procedure on the channel having a different count-down duration than the count-down duration of the first CCA procedure.

Abstract: Systems and methodologies are described that facilitate transitioning between states associated with a wireless terminal. The wireless terminal may transition to and/or from a split-tone on state, which may enable increasing overall user capacity related to a base station or sector. Further, such state transitions may reduce power consumption associated with the wireless terminal.

Abstract: Methods and apparatus for a Wireless Terminal (WT) to convey uplink traffic information, e.g., uplink channel resource requests, to a Base Station (BS) are described. Uplink transmission resources are requested for data corresponding to different priority levels. The WT keeps track of the BS's understanding of WT traffic through the use of a first queue which keeps track of the BS's estimate of WT's uplink queue status for different priority levels by following the same procedure the BS uses to update its estimate of WT queue status. The WT uses this tracked information along with actual traffic information it maintains in a second set of queue information to form uplink traffic channel requests to be transmitted to the BS. Methods used by the BS to interpret uplink traffic channel requests from WTs are also described. The BS maintains its own queue of requests and corresponding priority information for individual WTs.
