Blockage detection for wireless communications
Methods, systems, and devices for wireless communication are described. A user equipment (UE) may be configured with one or more parameters to support blockage detection for beamformed communication. The UE may receive a set of reference signals via a receive beam of a beam pair. The UE may detect a condition associated with a measured signal quality of a reference signal of the set of reference signals relative to a filtered signal quality of the set of reference signals. The condition may, in some examples, correspond to a drop of the measured signal quality at least a threshold amount below the filtered signal quality for at least a threshold duration of time. The UE may delete one or more signal quality values from a measurement database of the UE based on detecting the condition. The one or more signal quality values may be associated with the beam pair.

APPARATUS AND METHOD FOR GROUP BASED REPORTING BEAM MANAGEMENT
Some embodiments include an apparatus, method, and computer program product for using group based reporting for beam management in a 5G wireless communications system. A user equipment (UE) can determine based on a signal-to-interference-plus noise ratio (SINR) or reference signal received power (RSRP) measurement, a ranking of two or more beam combinations, and transmit the ranking to a 5G node B (gNB). The UE can receive from the gNB, a transmission configuration indicator (TCI) codepoint that identifies a combination of two or more beams, where the TCI codepoint is based at least on the ranking. The UE can receive simultaneous transmissions via the combination, and transmit a report to the gNB that identifies by the TCI codepoint, SINRs that corresponds to the combination. In some embodiments the UE can simultaneously transmit on a second combination identified by a sounding reference signal (SRS) resource indicator (SRI) codepoint.
METHOD AND APPARATUS FOR BEAM SWEEPING FOR CSI-RS MOBILITY MEASUREMENT
A first CSI-RS signal is received by user equipment through a first cell, and a second CSI-RS signal is received through a second cell. Respective QCL information can be available to determine a first Rx beam to measure the first CSI-RS signal and a second Rx beam to measure the second CSI-RS signal. In such a case, if the first CSI-RS signal and the second CSI-RS signal are fully overlapped, then the user equipment can i) alternate between measuring the first CSI-RS signal with the first Rx beam and measuring the second CSI-RS signal with the second Rx beam, or ii) measure only the first CSI-RS signal or the second CSI-RS signal. Other embodiments are described and claimed.
COMMUNICATION METHOD AND APPARATUS
This application relates to the field of communication technologies, and provides a communication method and apparatus, to determine a measurement periodicity in which a communication device performs layer 1 signal to interference plus noise ratio (L1-SINR) beam measurement based on a channel measurement resource (CMR) and an interference measurement resource (IMR). The method includes: A communication device receives a CMR and an IMR corresponding to the CMR. A terminal measures an L1-SINR of a receive beam based on the CMR and the IMR, to determine an optimal receive beam of the terminal. The CMR and the IMR are channel state information reference signal (CSI-RS) resources in different CSI-RS resource sets. The communication device determines a value of a first parameter based on repetition corresponding to a CSI-RS resource set corresponding to the CMR, and determines, based on the value of the first parameter, a measurement periodicity for measuring the L1-SINR.

Aspects described herein relate to identifying an aggressor node that transmits interfering signals that cause interference to signals received at the node, communicating a configuration for applying a phase shift to the interfering signals for forwarding to the node from a reflecting node with the phase shift applied, and communicating, from the reflecting node, the interfering signals with the phase shift applied to at least partially cancel the interference to the signals received at the node.
