Abstract: An enhanced linear combination codebook framework can support power allocation between transmission layers. Scaling between the layers of the codebook can be unequal so that power allocated between the layers can depend on the channel. For example, the network can configure the codebook to use radio resource control signaling to send codebook data to the user equipment.

Abstract: The described technology is generally directed towards indicating to a receiver (e.g., a user equipment) which antenna ports are assigned for channel state information reference signals (CSI-RS). The indicator can be sent as radio resource control configuration data and/or by physical layer signaling such as in downlink control information. The receiver computes CSI based on the assigned antenna port or ports, and the reported (e.g., joint) CSI helps avoid mismatched joint CSI used for scheduling when multiple transmit and receive points (TRPs) are communicating with the user equipment.

Abstract: Controlling and reducing overhead in control channels in 5G or other next generation communication systems is provided herein. In connection with a data transmission between a device and a network node device, an overhead management component (OMC) can analyze one or more factors associated with the device, including speed or Doppler metric(s) of the device, type of service associated with the device, historical HARQ statistics for the device, configured threshold value for CSI estimation, device capability regarding redundancy version support, or another factor(s). Based on analysis results, OMC can determine whether to utilize a single redundancy version state or a multiple redundancy versions state. If the single redundancy version state is selected, OMC can generate control information that does not include redundancy version information, the control information being communicated via a control channel OMC can communicate RRC signal to the device to indicate the determined redundancy version state.

Abstract: An adaptive cyclic redundancy check process for uplink control information signaling is provided to allow a number of cyclic redundancy check bits to be adjusted based on the likelihood of data being corrupted during transmission. In an embodiment, a base station device can send a cyclic redundancy check length map to a mobile device that indicates to the mobile device to use a specific number of cyclic redundancy bits to use per a specified payload size of uplink control information. Optionally, the mobile device can determine a number of cyclic redundancy bits to include in the uplink control information, and use two stage uplink control information signaling to indicate to the base station how many cyclic redundancy check bits there are in the succeeding stage.

Abstract: Various embodiments disclosed herein provide for switching between non-orthogonal and orthogonal multiple access protocols dynamically. A base station device can determine whether a user equipment device on a communication link should use a non-orthogonal multiple access system or an orthogonal multiple access system based on one or more attributes of the communication link, and send an indication of the selection to the user equipment device. The base station device can indicate the selection using a spreading factor parameter that is either equal to one or greater than one. If the spreading factor parameter is equal to one, that can indicate to the user equipment device to use an orthogonal multiple access system, whereas if the spreading factor parameter is greater than one, that can indicate to the user equipment device to use a non-orthogonal multiple access system.

Abstract: Described is a technology to reduce the interference between two or more transmit receive (Tx/Rx) points (TRPs) and improve the reliability for New Radio ultra reliable low latency communication (NR URLLC) applications. The technology operates in one aspect at a network node, and in another aspect at a user equipment. If a network device decides to use packet duplication, the network device can indicate duplication to the user equipment. The network device can send duplicate copies, e.g., via two different antenna panels, or can send one copy and coordinate with another network device (e.g., another cell) to send the other copy. When the user equipment receives the copies, the user equipment combines the data, e.g., via soft combining or concatenation into combined data, and decodes the combined data. Weights, such as corresponding to channel quality from each transmit source, can be used as factors in the combining of the data.

Abstract: Fast calculation of channel state information using demodulation reference signals (DM-RS) is provided herein. Channel state information is traditionally calculated based on the channel state reference signals (CS-RS). Demodulation reference signals, which are used for channel estimation for a data channel, are transmitted at different times than CS-RS however, and so some portions of the channel state information including layer indicator (LI) and channel quality indicator (CQI) can be calculated based on the demodulation reference signals, allowing a network to adapt more quickly to changing channel conditions, without having to transmit a CS-RS. Generally, precoding matrix indicator and rank indicator, which cannot be determined based on the DM-RS, don't change as often and are more stable over time, thus do not need to be calculated as frequently as the LI and CQI.

The operations can also comprise applying a second signal linearization to a group of output signals of a group of power amplifiers for a defined azimuth direction associated with channel frequencies of the group of output signals and applying a third signal linearization to the group of output signals for a defined elevation direction associated with the channel frequencies of the group of output signals.

Abstract: A base station device can transmit data via multiple data channels to a single user equipment device. Each of the multiple data channels can be configured and scheduled via respective downlink control channels to the user equipment device. In an embodiment, the first data channel can be mapped to multiple layers, with a modulation and coding scheme (MCS) assigned based on the average channel quality indicator (CQI) of the layers. One or more of the layers can have a higher CQI however, capable of supporting an additional transmission. The base station device can then facilitate establishing a second data channel to the layer with the higher CQI. The MCS assigned to the second data traffic channel can be based on the CQI of the layer, or based on a difference between the average CQI of the layers and the CQI of the layer.

Abstract: Facilitation of hybrid automatic repeat requests (HARQ) can comprise a system that acquires information about the capability of a mobile device. Next, the system can configure the mobile device with multiple physical uplink control channel (PUCCH) resources and a number of repetitions within a slot for each antenna port of the mobile device. A network node can then transmit a downlink control channel to the mobile device and indicate the PUCCH resources for each antenna port. Consequently, the system can then detect a HARQ acknowledgment (ACK) from the mobile device from all of the PUCCH resources.

Responsive to the result not indicating an error, extracting the information bits without decoding the received channel-encoded data block according to the channel code. Responsive to the result indicating an error, decoding the received channel-encoded data block according to the channel code to obtain decoded information bits. Other embodiments are disclosed.

Abstract: Various embodiments disclosed herein provide for a retransmission system that uses a hybrid system to signal to a receiver the retransmission of codeblock groups to reduce network overhead and bandwidth. The amount of bandwidth needed to signal to a receiver which codeblock groups are being retransmitted is directly proportional to the number of codeblock groups. Therefore, during retransmission, if the number of a codeblock groups is below a predetermined threshold, then explicit signaling can be performed, where the transmitter sends a bit map identifying the codeblock groups being retransmitted. If the number of codeblock groups is above the threshold however, can use a codeblock group confirmation bit in the control information sent to the receiver, where the values of the bit can inform the receiver how the retransmission will be performed.

Abstract: The disclosed subject matter relates to techniques for determining an appropriate aggregation level for a control channel resource set (CORESET). In one embodiment, a method is provided that comprises determining, by a first device operatively coupled to a processor, an aggregation level for application by a second device to decode candidate downlink control channels associated with a CORESET. The method further comprises transmitting, by the first device, aggregation level information to the second device indicating the aggregation level. As a result of the transmitting, the second device becomes configured to apply the aggregation level in association with attempting to decode the candidate control downlink control channels. In various embodiments, the aggregation level is determined based one or more criteria, including an aggregation level capability of the second device, a location of the second device relative to the first device, and a geometry associated with the second device.

Abstract: The described technology is generally directed towards having a transmitter in a wireless network generate and map reference signal sequences (e.g., for demodulation or other reference signal usage) so that the reference signal sequences are non-repetitive in a resource block. Avoiding repetition of the reference signal sequences reduces the peak-to-average power ratio in orthogonal frequency-division multiplexing (OFDM) systems. In one aspect, a transmitter device generates different reference signal sequences to avoid repetition of resource signal sequences, and maps the different reference signal sequences to appropriate (different) resource elements of a resource block. In one implementation, the different reference signal sequences can be based on different indexes of antenna ports. In an alternative implementation, the different reference signal sequences can be based on different code division multiplexing groups.
