  • Patent number: 11405155
    Abstract: Wireless communication techniques that utilize a general purpose (GP) reference signal for non-coherent millimeter-wave communication are discussed. The GP reference signal may have a special structure allowing it to be flexibly used by a mobile device for multiple purposes. A base station may determine a repetition factor for a repetitive intra-symbol GP reference signal mapping based on an event that triggered transmission of the GP reference signal. The base station may also map the GP reference signal to resource elements of a symbol based, at least in part, on the determined repetition factor of the repetitive intra-symbol GP reference signal mapping. The base station may also transmit the mapped GP reference signal. A mobile device may receive the GP reference signal and modify at least one parameter of a plurality of parameters based, at least in part, on processing of the GP reference signal.

  • Publication number: 20220225312
    Abstract: In embodiments, a base station may send to a user equipment (UE) a P3 beam management (BM) channel state information reference signal (CSI-RS) having two ports, and may receive from the UE a P3 BM report in response. The P3 BM report may include a proactive UE beam switch indication and a CSF report corresponding to the best UE beam determined by a UE based on the P3 BM CSI-RS. The base station may determine whether the P3 BM report includes an indication that the UE will perform a beam switch from a first UE beam to a second UE beam, and may determine a UE beam switch slot during which the UE will perform the beam switch. Starting at the beam switch slot, the base station may send a physical downlink shared data channel (PDSCH) transmission to the UE using the adjusted downlink transmission parameters.

  • Publication number: 20220225311
    Abstract: A base station may receive from a user equipment (UE) a proactive notification that the UE will perform a beam switch from a first UE beam to a second UE beam. In response, the base station may determine a beam switch slot on which the UE will perform the synchronized beam switch, and perform a link transient mitigation operation for communications with the UE after UE beam switch and until updating channel state information associated with a new UE beam. The base station may then receive from the UE channel state information feedback for a channel associated with the second UE beam, and adjust downlink data transmission parameters to be aligned with the second UE beam based on the received channel state information feedback (CSF). The base station may also adjust uplink data transmission parameters based on a sounding reference signal transmitted by the UE over the second UE beam.

  • Publication number: 20220191877
    Abstract: A transmitting device may select frequency domain resources for an alert transmission based on a severity level of the alert transmission. The transmitting device may determine a severity level of an alert transmission to be transmitted on one or more available channels. The transmitting device may determine a presence of one or more systems configured to transmit on one or more neighbor channels of the one or more available channels. The transmitting device may select, for the alert transmission, frequency domain resources within the one or more available channels based on the presence of the one or more systems and the severity level. The frequency domain resources for a highest severity level transmission are spaced further apart from the one or more neighbor channels in the frequency domain than resources for a lower severity level transmission. The transmitting device may transmit the alert transmission on the frequency domain resources.

  • Publication number: 20220167415
    Abstract: A method includes cellular vehicle-to-everything (CV2X) allocation collision detection and reporting. An allocation collision detection module detects control channel allocations from transmitting user equipments (UEs) in each time period of a group of time periods. A quantity of detected control channel allocations is determined in each time period. A report is then built and transmitted to at least one of the transmitting UEs. The report indicates collisions in each time period, based on the quantity and a location of the detected control channels in each time period, as well as based on a type of UE interface.

  • Publication number: 20220167414
    Abstract: A method detecting allocation collisions from transmitting user equipments (UEs) in sidelink channel resources. The colliding allocations are detected and the quantity of allocation collisions is determined. A collision report is transmitted to other sidelink UEs within the coverage zone. The collision report or collision notification provides an indication of sidelink resources having identified colliding allocations. The identified allocation collisions may be pruned to remove potentially intentional collisions before collision report transmission.

  • Patent number: 11330411
    Abstract: Methods, systems, and devices for wireless communications are described. The method may include an interference estimation procedure that measures interference from radio access technologies (RATs) different from cellular vehicle to everything (CV2X) on the CV2X network at a user equipment (UE). A UE may record measurements of interference on the CV2X network when no CV2X signal is present during the last symbol of a subframe. Then, the UE may estimate the noise plus interference measured during the empty symbol to improve noise plus interference whitening when decoding a subframe.

  • Publication number: 20220123856
    Abstract: Methods, systems, and devices for wireless communications are described to switch between waveform configurations based on an indicated modulation coding scheme (MCS) such that waveform switching may be signaled implicitly. A base station may configure a user equipment (UE) with a hybrid MCS table including MCS indexes associated with a first waveform configuration and MCS indexes associated with a second waveform configuration. The base station may schedule resources for an uplink transmission for the UE and may indicate an MCS index associated with the uplink transmission, using index from the MCS table. The UE may select a waveform configuration for the uplink transmission based on the MCS index. For example, the UE may compare the MCS index with a threshold MCS index of the hybrid MCS table and determine a waveform configuration associated with the MCS index based on whether the MCS index falls above or below the threshold.

  • Publication number: 20220104108
    Abstract: Aspects of disclosure relate to a UE reporting to a gNB time delays and phases of pilot signals received via multiple transmission paths in order for the gNB to pre-equalize a future transmission to the UE. The UE determines a first time delay for receiving a first pilot signal from a gNB via a first path, determines a second time delay for receiving a second pilot signal from the gNB via a second path, and generates a report based on the first time delay and the second time delay. The UE then sends the report to the gNB and receives a multi-TRP signal from the gNB via the first path and the second path, wherein the multi-TRP signal is pre-equalized for transmission based on the report to at least have a same time delay as a shorter one of the first time delay or the second time delay.
