Abstract: A grant-free transmission mode may be used to communicate small traffic transmissions to reduce overhead and latency. The grant-free transmission mode may be used in downlink and uplink data channels of a wireless network. In the downlink channel, a base station transmits packets to a group of UEs in a search space without communicating any transmission code assignments to the UEs. The UEs receive the downlink packets using blind detection. In the uplink channel, UEs transmit packets in an access space using assigned access codes which are either independently derived by the UEs or otherwise communicated by the base station using a slow-signaling channel. Hence, the grant-free transmission mode allows mobile devices to make small traffic transmissions without waiting for uplink grant requests.

Abstract: A user equipment (UE) for channel state information (CSI) feedback comprises a transceiver configured to receive, from a base station (BS), configuration information for the CSI feedback, the configuration information indicating a number of antenna panels (Ng) at the BS and a codebook mode, wherein Ng>1 and each of the antenna panels comprises antenna ports with a first polarization (P1) and antenna ports with a second polarization (P2). The UE further comprises a processor operably connected to the transceiver, the processor configured to identify the number of antenna panels (Ng) at the BS, identify a codebook for the CSI feedback based on the codebook mode configured between a first codebook mode and a second codebook mode, and generate the CSI feedback using the identified codebook. The transceiver is further configured to transmit the generated CSI feedback to the BS.

Abstract: Methods, systems, and devices for wireless communication are described. Some wireless communications systems may support communication between a base station and a user equipment (UE) during transmission time intervals (TTIs) having different lengths. The techniques described herein allow a UE to utilize appropriate configurations for communicating during a shortened TTI (sTTI) allocated for uplink communication (e.g., uplink control information transmissions). In one example, the UE may adjust a transmit power to use for transmitting uplink control information during an sTTI based on the length of the sTTI or based on the number of symbols allocated for transmitting the uplink control information in the sTTI. In another example, the UE may determine a frequency hopping pattern to use for transmitting uplink control information during an sTTI based on whether a portion of the sTTI is allocated for another transmission (e.g., a sounding reference signal (SRS) transmission).

Abstract: N nodes are assigned to a first layer of nodes having a first domain name server (DNS) anycast Internet Protocol (IP) address and a first fully qualified domain name (FQDN). M nodes are assigned to a second layer of nodes having a second DNS anycast IP address and a second FQDN. When a request to resolve the first FQDN for the first layer of nodes is received by a DNS of a node of the first layer and a load on the ES of the node is less than a threshold, the DNS handles the request by returning an edge server (ES) anycast IP address for the ES of the node. When the load on the ES is greater than the threshold, the DNS offloads the request by returning the second FQDN so that the second FQDN of the second layer is resolved to the second DNS anycast IP address.

Abstract: User equipment (UE) can determine a plurality of Downlink Control Information (DCI) formats that correspond to a plurality of transmission modes supported by a base station. When the UE receives a subframe of a radio frame from the base station, it can perform a blind search at the physical layer for a unique identifier associated with the UE in DCI of the subframe using at least one of the plurality of DCI formats. When the UE determines that the unique identifier was found during the blind search using a particular DCI format, it can identify a particular transmission mode that corresponds to the particular DCI format. The UE can then interpret data for the UE in the subframe according to that particular transmission mode.

Abstract: Proposed are a method and a device for transmitting a wakeup packet in a wireless LAN system. Specifically, a transmission device configures a wakeup packet and transmits the wakeup packet to a reception device. The wakeup packet, to which an OOK scheme is applied, includes a sequence comprising first information and second information.

In the K subcarriers to which the first sequence is applied, coefficients of subcarriers are set to 1 or ?1 by a unit of m subcarriers, and coefficients of the remaining subcarriers are set to 0.
