Abstract: Measurement resources are often limited in 5G and 4G-LTE communications. As a result, SMTC and CSI-RS measurement windows will occasionally be assigned to the same resource elements of a signal frame. This results in a collision that must be resolved, since both measurements cannot be performed simultaneously. The collision can be resolved using restriction, where overlapping resource elements are assigned to either the SMTC or the CSI-RS measurements, or can be resolved using measurement sharing, where overlapping resource elements are divided among the two measurements according to a measurement sharing factor. Various factors, including priority or window periodicity may be taken into account by the measurement rules that dictate collision resolution.

Abstract: Some embodiments include an apparatus, method, and computer program product for tracking reference signal (TRS) support of high speed use cases of 5G communications in a single frequency network (SFN), where a user equipment (UE) can measure a Doppler offset of a combined signal from two or more transmission reception points (TRPs) of the 5G communications system. A 5G node B (gNB) node can transmit a periodic, semi-persistent (SP), or aperiodic TRS with high measurement density that the UE uses to measure a Doppler offset of a combined signal. For example, the gNB can: trigger the aperiodic TRS based on a downlink assignment; and/or use lower layer signaling to arrange to transmit a semi-persistent TRS or a periodic TRS with a reduced periodicity. In some embodiments, the gNB can measure the Doppler offset based on an uplink signal, and transmit a TRS based on a pre-compensated Doppler frequency.

Abstract: Providing coverage enhancements for a user equipment (UE) includes decoding a random access channel (RACH) preamble received from a user equipment (UE) via a physical random access channel (PRACH). A number of repetitions associated with transmitting a random access response (RAR) over a physical downlink shared channel (PDSCH) may be determined in response to the RACH preamble. A transmission for the UE to be sent over a physical downlink control channel (PDCCH) may be encoded. The transmission may indicate the number of repetitions to the UE using one or more reserved bits of a downlink control information (DCI).

Abstract: A user equipment (UE) monitors a Physical Downlink Control Channel (PDCCH) during a random access channel (PRACH) procedure. The UE receives a physical random access channel (PRACH) resource on a first sub-band of a component carrier (CC), wherein the CC is divided into a plurality of sub-bands and receives a Type1-PDCCH CSS (Physical Downlink Control Channel Common Search Space) set on a second sub-band of the CC, wherein the Type1-PDCCH CSS set corresponds to the PRACH resource.

Abstract: Techniques of beamforming in reference signal (RS) transmissions, applicable to frequency ranges including frequencies between 52.6 GHz and 71 GHz, are described. Such techniques may include determining a communication channel is unoccupied for an initial duration, determining a number of communication slots of the communication channel to defer for transmission, and counting one or more communication slots of the communication channel that are not in use. The techniques may include determining the number of counted one or more communication slots is not equal to the determined number of communication slots of the communication channel to defer, and transmitting one or more data units based on the determination that the number of the counted one or more communication slots is not equal to the determined number of communication slots of the communication channel to defer.

Abstract: A user equipment (UE) is configured to handle physical downlink shared channel (PDSCH) transmissions during multi-transmission/reception point (TRP) operation. The UE receives a physical downlink control channel (PDCCH) transmission configured with downlink control information (DCI) in a single-DCI, multi-transmission/reception point (TRP) operation, wherein the DCI schedules reception of a physical downlink shared channel (PDSCH) transmission, determines whether or not a TCI field is configured in the DCI, when the TCI field is not configured in the DCI, determining a default beam based on a control resource set (CORESET) with the lowest ID in the PDCCH and when the TCI field is configured in the DCI, determining whether the TCI field indicates a TCI codepoint includes two TCI states.

Abstract: A user equipment (UE) reports channel state information for multiple transmission reception points (TRPs) to a network. The UE collects channel state information (CSI) corresponding to multiple transmission reception points (TRPs), receives a signal configured to trigger a semi-persistent CSI (SP-CSI) report from a first TRP of the multiple TRPs, generates a SP-CSI report that includes CSI corresponding to each TRP of the multiple TRPs and transmits the SP-CSI report to a cell associated with the multiple TRPs.
