Abstract: An apparatus of a user equipment (UE) includes processing circuitry configured to decode a master information block (MIB) using a set of physical broadcast channel (PBCH) symbols received within a downlink frame to obtain system frame number (SFN)information. The downlink frame includes multiple copies of the PBCH symbols within at least three subframes of the downlink frame. A system information block (SIB) may be decoded based on the SFN information, to obtain uplink channel configuration information. Random access channel (RACH) procedure may be performed with a base station (BS) based on the uplink channel configuration information, to obtain an uplink resource assignment. A connection setup completion message can be encoded for transmission to the BS using the uplink resource assignment. The set of PBCH symbols can include a set of four legacy PBCH symbols.

Abstract: A UE may estimate the power headroom value when using shortened Transmission Time Intervals (sTTI). In one implementation, the power headroom value may be calculated based on an estimation of the UE transmission power over two or seven OFDM symbols. Alternatively or additionally, the power headroom value may be calculated based on an estimation of the UE transmission power over the period of an sTTI. Alternatively or additionally, the power headroom value may be calculated based on an average of the UE transmission power over multiple sTTI periods in a subframe. Alternatively or additionally, the power headroom value may be calculated based on a maximum or minimum of the UE transmission power measured over multiple sTTI periods in a subframe. Alternatively or additionally, the power headroom value may be calculated based on UE transmission power measured in the first or the last sTTI period in a subframe.

Abstract: Technologies described herein provide mechanisms for a legacy UE traveling at a high speed (e.g., in a high speed train) to estimate the opposite Doppler shifts separately for different RRHs in an SFN so that the UE can more effectively receive a payload assigned by the SFN. In addition, the present disclosure provides UE signal process mechanisms to improve HST receiver performance such that good demodulation performance can be achieved without significant impacts on UE implementation. The present disclosure provides a specific framework to improve cellular SFN system operation using a combination of an SFN data signal transmissions from different RRHs and orthogonal non-SFN reference signal transmissions from different RRHs. A UE may estimate a propagation channel for each RRH using a reference signal and use this information to improve the demodulation of the combined SFN data signal.

Abstract: Systems and methods provide solutions for testing an 8Rx capable UE using test cases for 4Rx capable UEs. An example method establishes a connection from a first Tx source and a second Tx source to each of 8Rx antenna ports. The connection duplicates a fading channel from both the first Tx source and the second Tx source to each of the eight Rx antenna ports, and adds independent noise for each of the 8Rx antenna ports. One test scenario uses 4Rx supported RF bands by connecting four of the Rx ports with data from a system simulator, and the other four Rx ports are connected with zero input. Same requirements specified with 4Rx capable UEs are applied. Another test scenario uses 8Rx supported RF bands and applies lower dB SNR requirements than those specified for 4Rx tests.

Abstract: Systems and methods provide for beam detection in a wireless communication system. An apparatus for a UE may be configured to identify a plurality of CSI-RS resources corresponding to different Tx beams configured for measurement by the UE, measure an L1-RSRP for the plurality of CSI-RS resources, determine a selected Tx beam of the different Tx beams based on measured L1-RSRP values for the plurality of CSI-RS resources, and determine a measurement accuracy of a first L1-RSRP value corresponding to the selected Tx beam based on successful beam detection probability.

Abstract: Embodiments of a User Equipment (UE), Next Generation Node-B (gNB) and methods of communication are generally described herein. The UE receive training signals from a plurality of transmit-receive points (TRPs) associated with the gNB. Each training signal may comprise a reference signal resource identifier (ID) to indicate a corresponding TRP and a corresponding transmit direction of a plurality of transmit directions. The UE may, for each transmit direction of the plurality of transmit directions, determine an average signal quality measurement based on individual signal quality measurements in multiple receive directions. The UE may select, for reporting to the gNB, a subset of the average signal quality measurements to ensure that the average signal quality measurements excluded from the subset are less than or equal to a minimum value of the average signal quality measurements in the subset.

The method for indicating the service priority update includes: A priority management functional entity receives a service priority update request message sent by a user, where the update request message includes a service type identifier and a priority update indication identifier corresponding to the service type identifier; and the priority management functional entity sends a service priority update instruction message to a network side according to the update request message, where the update instruction message is used to instruct the network side to process a service corresponding to the service type identifier according to a priority level corresponding to the priority update indication identifier. In the embodiments of the present invention, priority control is exercised on all types of services of the user in an emergency.
