Abstract: A method for wireless communication by a network node includes transmitting, to a group of user equipment (UEs), radio resource control (RRC) signaling to configure a function for enabling and disabling hybrid automatic repeat request (HARQ) feedback for a set of N instances of a multicast transport block (TB). The method also includes transmitting, to the group of UEs, the set of N instances of the multicast TB. The method further includes transmitting, to the group of UEs, a downlink control information (DCI) message on a group-common physical downlink control channel (PDCCH) with a cyclic redundancy check (CRC) scrambled by a group-common radio network temporary identifier (RNTI) configured for the group of UEs. The method also includes receiving, from one or more UEs of the group of UEs, a HARQ feedback message associated with one or more instances of the set of N instances after transmitting all N instances.

For instance, in one example, a method includes obtaining real-time network performance metrics directly from a user endpoint device operated by a customer of a telecommunication service provider network, correlating the real-time network performance metrics with data from another data source, wherein the data includes data other than network performance metrics, and adjusting an infrastructure of the telecommunication service provider network in response to an insight gleaned through the correlating.

Abstract: According to an embodiment of the present disclosure, a method for transmitting, by a user equipment (UE), uplink data in a wireless communication system supporting a narrowband Internet of things (NB-IoT) system includes: receiving information related to a preconfigured uplink (UL) resource (PUR) for transmitting the uplink data in an RRC connected state; and transmitting the uplink data by using the preconfigured uplink resource (PUR) in an RRC idle state. In the transmitting of the uplink data, when the preconfigured UL resource (PUR) is a dedicated resource and there is no data to be transmitted in the preconfigured UL resource (PUR), transmission of the uplink data is skipped.

Abstract: Enhancements to downlink feedback information (DFI) signaling is disclosed. According to the disclosed aspects, indications of DFI presence in downlink control information (DCI) messaging are provided that limit any increase to DCI overhead for uplink grants. In a first aspect, DFI presence may be signaled using unused or disallowed DCI variable states for indication of DFI presence. In another aspect, a separate bit may be added to a DCI message for indicating DFI presence. Additional aspects include repurposing DCI fields which are specific to cell radio network temporary identifier (C-RNTI)-based uplink grants, or may defining a new RNTI (e.g., DFI-RNTI) for indicating DFI presence. Further aspects may provide for radio resource control (RRC) signaling that configures which DCI variable state can be used to indicate DFI presence.

Abstract: A UE receives, from a base station or a component of the base station, at least one DL grant after a reception of an UL grant, the at least one DL grant being associated with a DL cDAI value and a DL tDAI value, the UL grant being associated with an UL tDAI value and scheduling a plurality of PUSCH repetitions. The UE calculates a total number of DL grants sent to the UE based on the DL cDAI value. The UE adjusts the total number of DL grants if there is a difference between the total number of DL grants and the UL tDAI value. The UE transmits, to the base station, a HARQ codebook in at least one of the plurality of PUSCH repetitions, a size of the HARQ codebook being based on the adjusted total number of DL grants.

Abstract: This disclosure provides systems, methods, and apparatuses for supporting network transmissions using unicast sidelink communications. A base station (BS) may transmit a set of encoded packets to a number of user equipment (UEs) and receive feedback messages from the UEs that indicate sets of decoded packets. Based on the feedback messages, the BS may transmit an updated set of encoded packets based on a difference between the set of encoded packets and the union of decoded packets. The BS may transmit an instruction to a first UE to transmit a unicast sidelink communication to a second UE that includes a set of missed packets that includes one or more decoded packets that were decoded by the first UE but were not decoded by the second UE. The first UE may transmit the unicast sidelink communication to the second UE.

Abstract: A wireless device receives indications of: a first scheduling request (SR) resource corresponding to first logical channel(s) having a first logical channel prioritization (LCP) mapping to first radio resources; and a second SR resource corresponding to second logical channel(s) having a second LCP mapping to second radio resources. A buffer status report (BSR) is triggered in response to data becoming available for the second logical channel(s). First uplink grant(s) indicating a first radio resource of the first radio resources is received. An SR for transmission of the BSR is triggered in response to the first radio resource not meeting the second LCP mapping configured for the second logical channel(s) that triggered the BSR. The SR is transmitted via the second SR resource selected based on the second logical channel(s) triggering the BSR. The BSR is transmitted via a second radio resource of the second radio resources.

Abstract: The present application relates to the field of wireless communications. Disclosed are a resource selection method and device, a terminal, and a medium. The method comprises: determining a resource monitoring window, wherein the resource monitoring window comprises some of time slots before a time slot m where a selected resource is located; and when the monitoring result of the resource monitoring window is that a resource conflict occurs between the selected resource and a reserved resource of a second terminal, performing resource reselection for the selected resource.
