  • Publication number: 20210067978
    Abstract: Methods, systems, and devices for wireless communications are described. A user equipment (UE) may utilize synchronization signal block (SSB) and channel state information reference signal (CSI-RS) based beam management to select beams for communicating with a base station. For example, a UE may receive, from a base station, control signaling that configures the UE to monitor a set of SSBs and a set of reference signals. The UE may select a subset of the set of SSBs based on measuring a first signal metric for each SSB of the set of SSBs. In some examples, the UE may select a reference signal subset of the set of reference signals that correspond to the subset of the set SSBs, and may communicate a data transmission with the base station using a first beam selected based on measuring a second signal metric for each reference signal in the reference signal subset.

  • Publication number: 20210037592
    Abstract: Disclosed are techniques for enabling a user equipment (UE) operating in carrier aggregation mode to use different connected mode discontinuous reception (CDRX) configurations for different sets of component carriers associated with different sets of numerologies. For example, in Frequency 1 (FR1) plus Frequency 2 (FR2) carrier aggregation (i.e., one or more FR1 component carriers and one or more FR2 component carriers), a different CDRX can be configured for FR1 than for FR2. In inter-band carrier aggregation (i.e., one or more component carriers in one frequency band and one or more component carriers in another frequency band), CDRX can be configured per band. For mixed numerologies carrier aggregation (i.e., one or more component carriers with a first numerology and one or more component carriers with a different numerology), CDRX can be configured per cell group, where each cell group contains a single numerology or mixed numerologies.

  • Patent number: 10887904
    Abstract: Methods, systems, and devices for wireless communications are described. A base station may implement cross-carrier scheduling. A user equipment (UE) may identify a minimum scheduling delay and may receive a downlink grant on a first CC. The UE may further identify the slot in which a downlink data transmission corresponding to the downlink grant will be received, and may identify the slot such that the minimum scheduling delay is satisfied. The UE may the receive the downlink data transmission, as indicated in the downlink grant, in the identified slot. In some examples, the UE and the base station may alternate between a long minimum scheduling delay and a short minimum scheduling delay. In some examples, the UE and the base station may alternate between a cross-carrier mode, and a self-scheduling mode.

  • Publication number: 20200403656
    Abstract: Aspects are provided allowing a UE configured for Type II channel state feedback (CSF) to determine based on one or more antenna configurations or channel conditions whether to use the Type II codebook or to revert to a Type I codebook when computing CSF. Based on this determination, the UE may compute CSF based on the Type I codebook in situations where the performance gain of Type II codebooks may be reduced, thereby saving computational power, transmission power, and/or overhead when computing and reporting CSI feedback. The UE may subsequently transmit the CSF computed based on the Type I codebook in the allocated resources for Type II CSI feedback without the need for a separate signaling format, thereby simplifying and enabling reuse of the CSI feedback procedure.

  • Publication number: 20200367171
    Abstract: Methods, systems, and devices for wireless communications are described to enable a user equipment (UE) to employ a discretionary on mode (e.g., powering receiver circuitry) in order to conserve power during discontinuous reception. The UE may discretionarily cut down an on time duration by delaying wake-up (e.g., powering on receiver circuitry) or by sleeping (e.g., powering down receiver circuitry) during portions of an on duration. The UE may also discretionarily skip one or more on durations. The UE may use hybrid automatic repeat request retransmissions to receive information that may be missed when sleeping during a configured on duration. The UE may evaluate one or more conditions in order to determine whether to employ a discretionary on mode. For example, the UE may determine to conserve power based on one or more of a data traffic type, a battery level, a channel condition, a retransmission policy, or physical layer activities.
