A method of transmitting an uplink signal for a terminal configured to support multiple TTI (transmission time interval) lengths in a wireless communication system, includes mapping rank indicator (RI) information to elements on a column of an element matrix in a descending order of a row index from a maximum value of row indexes of the column; mapping ACK/NACK (acknowledgement/non-acknowledgement) information to the elements on the column in a descending order of the row index from a maximum value of the row indexes of the column among remaining elements except the elements of the column used for the RI information; and transmitting the uplink signal including the RI information and the ACK/NACK information.

Channel state information (CSI) can be transmitted to a network node incrementally to increase network efficiency. The CSI feedback framework can be enhanced by allowing a user equipment (UE) to report multiple sets of CSI feedback, where each set can comprise a rank indicator (RI), a pre-coder matrix indicator (PMI), and a channel quality indicator (CQI). Since a different set may have a different sub-band, the CSI feedback framework can support the sub-band rank, wherein rank data from a wideband and the sub-band can be used by the network.

A method and an apparatus in a multiple-input multiple-output (MIMO) wireless communication system are provided. A signal is received over a channel. The channel is decomposed into a plurality of virtual channels. Symbol detection is performed on each of the plurality of virtual channels. Values are obtained for the channel. Decoding is performed using the values to output a decoded symbol value of the received signal.

A network device may receive data for multiple wireless channels. The network device may determine an activity level or score for one or more of the wireless channels based on the received data. The network device may determine, based on the activity level for each wireless channel, a portion of the wireless channels that satisfy an activity level threshold. The network device may generate a ranking of the portion of the wireless channels that satisfy the activity level threshold. The ranking may be based on the activity level or score of each wireless channel. The network device may determine a wireless channel based on the ranking and may send an indication of the wireless channel to a user device.

Methods, systems, and devices for wireless communications are described. A method of wireless communication at a user equipment (UE) is described that may include receiving a data packet transmission over a wireless channel from a base station. The method may further include determining a set of intrinsic log likelihood ratios (LLRs) based at least in part on the data packet transmission and determining an accumulated capacity for the wireless channel based at least in part on the set of intrinsic LLRs. The method may also include determining a channel quality indicator index or a transmission rank for the wireless channel based at least in part on the accumulated capacity and transmitting a feedback message that indicates the channel quality indicator index or the transmission rank for the wireless channel to the base station.

A method of a user equipment (UE) in a wireless communication system is provided. The method comprises receiving, from at least one transmission and reception point (TRP) of a group of (N) TRPs, channel status information (CSI) configuration information, determining a CSI report based on the CSI configuration information, identifying, based on the configuration information, one or more TRPs of the group of (N) TRPs to transmit the determined CSI report, and transmitting, to the one or more TRPs, the determined CSI report over an uplink channel. The determined CSI report includes a TRP indicator for selecting (M) TRPs of the group of (N) TRPs, and CSI for each of the selected (M) TRPs, wherein N is greater than one, and wherein M is greater or equal to 1, and less or equal to N.

A user equipment (UE) transmits over multiple antenna ports and receives a control message from a base station in a wireless communication network. The control message comprises a precoding matrix indication field configurable to a first, second, and third configuration. The first configuration identifies precoding matrices in both a first set of precoding matrices and a second set of precoding matrices. The second configuration identifies precoding matrices in the second set of precoding matrices but not in the first set of precoding matrices. The third configuration identifies precoding matrices in a third set of precoding matrices in addition to the first and second sets. The precoding matrices in the sets are precoding matrices for transmissions from the UE. Each set of precoding matrices corresponds to a respective coherence capability. For a maximum of four spatial layers, the first, second, and third configurations occupy 5, 4, and 6 information bits, respectively.

According to one or more embodiments, a network node configured to communicate with a wireless device is provided. The network node includes processing circuitry configured to: receive multilayer feedback; determine a beamformer for transmission of a first quantity of transmission layers where the beamformer is based at least on information, in the multilayer feedback, that is associated with a second quantity of transmission layers, where the first quantity of transmission layers is a less than the second quantity of transmission layers; and cause the transmission using the beamformer.

Techniques are described herein for determining a priority ranking for channel state information (CSI) reports based at least in part on a reliability parameter, a latency parameter, or both of resources allocated to a user equipment (UE). In some wireless communications systems, ultra reliable low latency communication (URLLC) services may be interspersed with enhanced mobile broadband (eMBB) services. The UE may perform a CSI report prioritization procedure to account for reliability parameters, latency parameters or both. In some cases, CSI reporting for resources associated URLLC services may receive higher priority than CSI reporting for eMBB services. The UE may be configured to determine reliability parameters and/or latency parameters based on signaling received from the network or from determining changes to one or more configurations of the UE. In some cases, the priority ranking of the CSI report may be based at least in part on a slot set identifier.

Embodiments of the present disclosure describe methods, apparatuses, and systems for enhanced control signaling using full-duplex communication in wireless communication networks. A base station may schedule a first user equipment (UE) for primary access to a set of time-frequency resources in a first communication direction (e.g., uplink or downlink). The base station may additionally schedule a second UE for secondary access to the same set of time-frequency resources in a second communication direction that is the opposite of the first communication direction. The secondary access may be used to communicate supplemental control information, such as a channel quality indicator (CQI) and/or modulation and coding scheme (MCS) feedback, hybrid automatic repeat request (HARQ) feedback, and/or multiple input multiple output (MIMO) feedback (e.g., including a rank indicator (RI) and/or a pre-coding matrix indicator (PMI). Other embodiments may be described and claimed.
