Abstract: In one embodiment, the method includes receiving, at a first device and from a second device, an indication of a resource range, related to a transmission of a demodulation reference signal associated with a control channel reception, including at least one of at least one entire resource element group, or at least one entire control channel element; and wherein the resource elements located in the resource range are dedicated for the transmission of the demodulation reference signal and unavailable for a transmission of control information from the second device; receiving the demodulation reference signal based on the indication; and decoding a control channel between the first and second devices based on the demodulation reference signal.

Abstract: Systems, methods, apparatuses, and computer program products for physical broadcast channel (PBCH) extension to manage extended master information block (MIB) are provided. A user equipment (UE) may determine whether an MIB extension exists. If the MIB extension exists, then the UE may determine an extended PBCH time-frequency location.

Abstract: A UE may be enabled to provide low latency, high reliability, and power savings. If a message of the UE is delay-sensitive, the UE may indicate to a gNB that fast retransmission scheduling may be necessary if a packet is not received over PUSCH. After transmitting the packet, the UE may monitor PDCCH for an indication that retransmission is required. This monitoring may occur sooner than a PDCCH monitoring period would otherwise allow. If the UE receives a DCI indicating that retransmission is required, the UE may retransmit the packet as well as an indication for a fast transmission request. This process may continue until an acknowledgement of the received packet is received in DL or no DCI indicating retransmission is received in DL. Accordingly, the gNB may quickly receive the retransmitted packet while the UE saves power by only performing additional monitoring when requested.

Abstract: Techniques of transmitting and receiving HARQ feedback for point to multipoint data packets include using two different PUCCHs for providing ACK/NACK feedback to a sequence of point-to-multipoint (PTM) data packets. For example, when a gNB sends PTM data packets (e.g., as part of a subscription) to subscriber UE's, each UE sends ACK/NACK messages in response over a first PUCCH which has a smaller bandwidth than a conventional PUCCH under which full uplink control information (UCI) may be sent. In some implementations, the ACK/NACK messages are a single bit. In response to a NACK message from a UE, the gNB allocates a second PUCCH to the UE. The UE then send additional details to explain the NACK message. In some implementations, the additional details include an identifier of a missing data (e.g., packet m of n).

Abstract: Example embodiments of the present disclosure relate to devices, methods, apparatuses and computer readable storage media for counting of devices. In example embodiments, a first device receives, from a second device, a first configuration associated with an event to trigger transmission of a counting signal from the first device to the second device. When the event occurs, the first device transmits, to the second device, at least the counting signal to enable the second device to count the number of devices for determining a type of signals.

Abstract: Embodiments of the present disclosure relate to communications with preconfigured uplink resources (PUR). A method implemented at a terminal device comprises identifying a need to change a transmission configuration of the terminal device, the terminal device being in a transmission mode with a set of preconfigured uplink resources (PURs) allocated for the terminal device to transmit user data to a network device; and in response to identifying the need to change the transmission configuration, transmitting control information to the network device using a first PUR in the set of PURs, the control information comprising information relevant to the change of the transmission configuration. In this way, it is possible to enable the terminal device to save power, time, and resources by bypassing a full random access procedure when the transmission configuration is needed to be changed.
