Abstract: Intelligent hybrid automatic repeat request (HARQ) feedback can better support link adaption. Thus, in addition to the traditional HARQ feedback, which is to relay acknowledgement (ACK) and negative acknowledgement (NAK) data based on a decoding result, a new state for the HARQ feedback can be represented as “ACK+”. Consequently, ACK+ can be used to indicate to the network that a modulation and coding scheme (MCS) of a current data packet is too conservative, and the user equipment (UE) is capable of supporting a more aggressive MCS.

Abstract: The disclosed subject matter is directed towards semi-static or dynamic shifting of New Radio demodulation reference signals to avoid collisions with LTE cell specific reference signals (LTE CRS) in a physical downlink shared channel symbol (PDSCH). In dynamic spread spectrum (DSS) deployments, where NR PDSCH mapping type B is used, e.g., to allow for two NR physical downlink control channel symbols, when the NR PDSCH starts on a symbol carrying LTE CRS, the NR DMRS of the NR PDSCH is shifted to the first symbol of the NR PDSCH not carrying LTE CRS. Whether mapping type A or mapping type B, shifting the symbol containing NR DMRS facilitates the use of two DMRS symbols without colliding with LTE CRS.

Abstract: Various embodiments disclosed herein provide for a codeblock segmentation configuration system. A base station can configure the segmentation rate or segment size, which can control the number of codeblock segments a transport block is segmented into, based on the transmission reliability and predicted interference to a mobile device. An increased number of segments can improve throughput and efficiency when interference is low and signal to noise ratios are high, but can increase latency when interference is high and signal to noise is low. The base station can determine or predict transmission reliability based on the speed of mobile devices, the location and/or distance to the mobile device, as well as the long term signal to noise ratios.

Abstract: The described technology is generally directed towards a composite HARQ-ACK response that contains information corresponding to a current HARQ-ACK composed with one or more previous HARQ-ACKs in a single uplink transmission.

Abstract: A network node and a wireless device as well as respective method performed thereby for communication with each other are provided. The method performed by the network node comprises receiving, from the wireless device, a measurement report indicating a channel quality of the channel between the network node and the wireless device; and determining whether the channel quality is acceptable or unacceptable.

Abstract: Channel state information reference signal transmission can be used to estimate channel state information. Although resources needed for channel state information reference signals can be small, when multiple bandwidths are deployed within the same orthogonal frequency division multiplexing bandwidth, estimating the channel state information can comprise a channel state information reference signal resource grid for every bandwidth. Therefore, time-frequency resources for channel state information reference signals can be high and occupy a lot of bandwidth, thereby reducing the number of resources for data transmission. Therefore, a non-orthogonal design for channel state information reference signals for a 5G air interface can mitigate bandwidth loss in a 5G network.

In response to this determination, the demodulation reference signal configuration can be modified.

Abstract: Reporting sub-band channel quality is described. For instance, instruction data representative of an instruction to select a provisional channel quality indicator is received by a mobile device from network equipment based on aperiodic channel quality data associated with a sub-band, wherein the instruction data is based on a configured bandwidth part associated with a communication between the network equipment and the mobile device, and wherein a channel quality indicator comprises a full resolution associated with the sub-band. Further, in response to the receiving, the mobile device can select the provisional channel quality indicator based on the instruction data. Furthermore, in response to the selecting, the mobile device can facilitate sending the channel quality indicator to the network equipment in accordance with a full resolution instruction associated with the full resolution.

Abstract: The described technology is generally directed towards scheduling downlink transmissions using orthogonal resources (that is, resources that avoid or at least reduce interference) when a network configures a user equipment (UE) with a multiple slot configuration to repeat the HARQ-ACK information for a transmission. By using orthogonal resources, a downlink transmission can be scheduled in consecutive time slots instead of waiting for the repeated HARQ-ACKs to complete.

Abstract: Aspects of the subject disclosure may include, for example, obtaining a received channel-encoded data block having information bits, a transmitted error-check value, and redundant code bits. The redundant code bits correspond to a channel code applied to the received channel-encoded data block prior to transmission via a communication channel. A channel code type is identified and responsive to it being systematic, the information bits and the transmitted error-check value are obtained without decoding according to the channel code. The received channel-encoded data block is checked according to the transmitted error-check value to obtain a result. 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.
