Abstract: Embodiments of this disclosure provide techniques for determining a device's beam correspondence status. As used herein, a device is considered to have “beam correspondence” when the device's TX and RX antennas satisfy a calibration criteria. In one example, a device's TX and RX antennas satisfy the calibration criteria when a difference between quality parameters corresponding to reference signals transmitted and received using corresponding TX and RX beams is less than a threshold. In another example, a device's TX and RX antennas satisfy the calibration criteria when a list of indices ranking the device's TX beams matches a list of indices ranking the device's RX beams. The lists of indices may be derived by transmitting and receiving references signals according to the devices RX and TX beams, and then generating list of indices based on quality parameters of the respective RX and TX beams.

Abstract: A communication device includes a level one (L1) processing element configured to measure downlink (DL) reference signals from multiple beams received via a transceiver to generate L1 data describing the multiple beams. The device also includes a level two (L2) processing element configured to consolidate, select, or filter the multiple beams responsive to the L1 data to produce L2 data corresponding to one or more of the multiple beams in a first cell that are consistent with preconfigured parameters. Furthermore, the device includes a level three (L3) processing element coupled to the L1 and L2 processing elements and configured to generate L3 data corresponding to one or more of the multiple beams in each of the first cell and a second cell. The device also includes a report generator coupled to the L1, L2 and L3 processing elements and configured to generate a report for a mobility event.

Abstract: Embodiments are provided for managing and mitigation contention of high reliability and low latency transmissions in wireless communications networks. According to an embodiment, a network entity indicates a first grant to a first device associated with a first service. The first grant includes a first resource for transmitting for the first service and a second resource for retransmitting for the first service. The network entity also indicates a second grant to a second device associated with a second service. The second grant includes the first resource for transmitting for the second service and a third resource for retransmitting for the second service. A third grant is also indicated to a third device associated with a third service. The third grant includes the first resource for transmitting for the third service. The first service and the second service have higher transmission reliability and latency requirements than the third service.

Abstract: A method of link adaptation is described including establishing, using a first serving point, a multi-user full duplex mode wherein the multi-user full duplex mode enables a downlink to a first wireless device and an uplink from a second wireless device. The first serving point requests from the first wireless device a first channel quality indicator indicating channel quality between the serving point and the first wireless device in a full duplex time period and a second channel quality indicator indicating channel quality between the serving point and the first wireless device in non-full duplex time period. The full duplex mode is evaluated using the first and second channel quality indicators. At least one parameter of the full duplex mode is adjusted based on the evaluating.

Abstract: The disclosure relates to technology for identifying a user equipment beam index in a base station. The base station indicates one or more resources assigned to the user equipment within a beam failure random access channel (BRACH) resource, and transmits one or more synchronization signal block resources and one or more new beam identification reference signal resources to the user equipment. The base station then receives one of the resources from a group of the one or more resources within the BRACH resource assigned to the user equipment corresponding to the BRACH resource, and identifies a preferred beam index of the user equipment based on information in the BRACH resource and the received one of the resources.
