Abstract: Aspects relate to dynamically modifying channel state information (CSI) settings, such as CSI report settings and/or CSI resource settings, utilized by a user equipment (UE) in reporting CSI to a base station. For example, a UE may identify at least one parameter associated with a CSI setting and provide a recommendation to modify the CSI setting based on the at least one parameter to a base station. The recommendation may include, for example, an optimized configuration of the CSI setting or soft output, such as an uncertainty level or confidence level associated with the CSI setting. The base station may then select the optimized CSI setting based on the recommendation and provide the optimized CSI setting to the UE for use in generating and transmitting CSI reports to the base station. Other aspects, features, and embodiments are also claimed and described.

Abstract: Various aspects of the disclosure relate to beam information for independent links. For example, beam information for one link may be sent on at least one other link. In some aspects, the independent links may involve a first device (e.g., a user equipment) communicating via different independent links with different devices (e.g., transmit receive points (TRPs) or sets of TRPs). For example, the first device may communicate with a second device (e.g., a TRP) via a first link and communicate with a third device (e.g., a TRP) via a second link. In some scenarios, one link can indicate beam switching for at least one other link. In some scenarios, one link can indicate link recovery for at least one other link. In some scenarios, one link can indicate link failure for at least one other link.

Abstract: Methods, devices, systems, and computer-readable media for supporting position estimation are disclosed. A method at a first user equipment (UE) device may comprise sending or receiving, via a sidelink channel, a ranging signal between the first UE device and a second UE device. The method may further comprise obtaining at least one ranging measurement based on the sending or receiving the ranging signal between the first UE device and a second UE device. The method may further comprise broadcasting, via the sidelink channel, (1) the at least one ranging measurement with a reference to the second UE device or (2) a position estimate for the first UE device based on the at least one ranging measurement.

Abstract: Wireless communications systems and methods related to indicating antenna configuration information and neural network information are disclosed. Neural network information may be selected for an encoder side based on an antenna configuration of a first device housing the encoder. This information may be transmitted with the antenna configuration information to a second device, which may jointly train the neural network with the first device. The first device may further transmit one or more weights after the training, which are stored with the antenna configuration information at the second device as well. When a third device with similar antenna configuration as the first device establishes communication with the second device, the second device may transmit neural network information, as well as weights, to the third device. The third device may use this information, instead of default information, to speed up neural network initialization and training.

Abstract: Methods, systems, and devices for wireless communication are described. Discontinuous reception (DRX) operation may be configured differently on enhanced component carriers (eCCs) than on other component carriers, including a primary cell (PCell). In some cases, a user equipment (UE) may be configured with several different eCC DRX modes. An eCC DRX configuration may, for example, be coordinated with downlink (DL) transmission time interval (TTI) scheduling so each DRX ON duration may correspond to a DL burst duration of the corresponding eCC. The eCC DRX ON durations may also be scheduled according to hybrid automatic repeat request (HARQ) process scheduling. In some examples, eCC DRX ON durations may be based on listen-before-talk (LBT) procedures. In some cases, eCC DRX ON durations may be configured to contain an uplink (UL) burst to enable channel state information (CSI) reporting. The eCC DRX may also be configured to minimize interruption of the PCell.

Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a wireless communication device (WCD) may train a bitwise autoencoder neural network to obtain a constellation mapping. The WCD may determine a bit position ordering for bit positions of modulated symbols associated with the constellation mapping based at least in part on error protection levels of bit positions associated with the constellation mapping. The WCD may perform bit interleaving for one or more coded bits of a communication, based at least in part on the bit position ordering of the constellation mapping, to obtain one or more interleaved bits. The WCD may generate one or more modulated symbols for the communication by mapping the one or more interleaved bits using the constellation mapping. The WCD may transmit, to a receiver device, the one or more modulated symbols for the communication. Numerous other aspects are described.

Abstract: New radio (NR) transmission opportunity (TxOP) structure having flexible starting points are disclosed for wireless communications. When a typical listen before talk (LBT) procedure is performed, the transmitting node will not know ahead of time when the LBT will pass and, thus, when data transmissions can start. NR systems may include a mini-slot design for accommodating transmission units smaller than a slot. Aspects of the present disclosure provide for flexibly increasing the number of potential starting transmission boundaries depending on when the LBT pass is detected. Alternative aspects of the present disclosure determine the potential starting transmission points using a mini-slot based design, a floating slot based design, or a punctured slot based design with a code block group (CBG) level retransmission mechanism.

Abstract: Multiple modulation and coding scheme (MCS) tables for new radio (NR) networks is disclosed. Multiple MCS tables are defined with different sets of MCS values selected for improved performance in various transmission conditions. The multiple MCS tables may be known to base stations and user equipments (UEs) in the network. A serving base station may determine a set of transmission characteristics related to a transmission environment of a UE. The base station selects one of the MCS tables of the multiple MCS tables based on the set of transmission characteristics. The selected MCS table includes MCS values that may provide improved performance for the UE considering one or more of the characteristics of the set of transmission characteristics. The base station will then transmit an indication of the selected MCS table to the served UE.

Abstract: Methods and apparatuses for wireless communications are described. The aspects relate to a frame structure for new radio shared spectrum. For instance, the frame structure may provide shared medium access by multiple operators in a new radio shared spectrum system. Specifically, the present aspects provide for utilizing reservation preambles associated with a distinct operator for announcing to other operators a reservation of at least one transmission opportunity of a given frame in the new radio shared spectrum.

Abstract: Methods, systems, and devices for wireless communications are described. A user equipment (UE) having partially coherent antennas may be configured for simultaneous transmissions on groups of antennas. To achieve the benefits of simultaneous transmissions using groups of antenna that are partially coherent, without having the transmissions affect each other, the UE may apply a hybrid closed-loop multiple-input multiple-output (MIMO) scheme among each antenna in the antenna groups where phase coherence can be maintained Following the hybrid closed-loop MIMO scheme, the UE may apply a transparent diversity scheme across each antenna of the groups. Alternatively, the UE may first apply the transparent diversity scheme and next apply the hybrid closed-loop MIMO scheme. By applying a hybrid closed-loop MIMO scheme, and a transparent diversity scheme, the UE may fully realize its resources and contribute to an improved spatial diversity for a MIMO system.
