  • Publication number: 20210321226
    Abstract: Methods, systems, and devices for multicast wireless communications are described. A base station may configure a user equipment (UE) for providing feedback for multicast transmissions from the base station while the UE is in an inactive or idle mode. Based on a configuration sent to the UE from the base station, the UE may determine resources or a timing advance (TA) to use for transmission of a feedback message for multicast communications. A base station may configure a UE with multiple TA commands, each corresponding to a TA value and a set of channel metrics associated with group of cells including a serving cell of the UE. Based on measure channel metrics at the UE, the UE may determine a TA to use for multicast feedback. TA values may be determined using neural network modeling.

  • Publication number: 20210320674
    Abstract: Methods, systems, and devices for wireless communications are described. A communication device, otherwise known as a user equipment (UE) or a base station may select a sequence from a set of sequences for conveying a payload including a set of bits. A length of the selected sequence may be based on a number of time periods for conveying the payload and a number of frequency tones for conveying the payload. The communication device may apply an interleaving function to the selected sequence to generate an interleaved sequence, and transmit the payload including the set of bits using the interleaved sequence. Likewise, the communication device may receive the payload including the set of bits using an interleaved sequence, and apply an interleaving function to de-interleave the interleaved sequence to generate a selected sequence. The communication device may thereby decode the payload based on the selected sequence.

  • Publication number: 20210314021
    Abstract: Methods, systems, and devices for wireless communications are described. In some systems, a user equipment (UE) and a base station may support beamforming communication techniques and may communicate using one or more beams. The UE may support a bandwidth part (BWP) hopping pattern and may perform a beam failure detection (BFD) procedure across the supported BWPs. While performing the BFD procedure, the UE may declare beam failure and may determine whether to switch to an anchor BWP to initiate a beam failure recover (BFR) procedure or to remain on an active BWP to initiate the BFR procedure. In some implementations, the UE may determine whether to switch to the anchor BWP or to remain on the active BWP to initiate the BFR procedure based on an indication from the base station.

  • Publication number: 20210306125
    Abstract: Quasi-colocation (QCL) indication is discussed after downlink transmission. In the management of multiple transmission-reception point (TRP) downlink transmissions, a second indication of a QCL assumption for a particular downlink transmission may be transmitted to receiving user equipment (UEs) after transmission of the downlink transmission. Once a TRP passes a listen before talk (LBT) procedure in a first time interval, it may send a first downlink control information (DCI) with indication of a first QCL assumption for the transmission in the first time interval. The TRP then transmits the downlink transmission intended for part of the multi-TRP downlink transmission. Upon receiving an indication that another of the TRPs was unsuccessful in its part of the multi-TRP transmission, the TRP may transmit a second DCI in a subsequent time interval with adjustments to the QCL assumption for the UEs to use in processing the downlink transmission from the first time interval.

  • Publication number: 20210306053
    Abstract: Methods, systems, and devices for wireless communications are described in which a base station and a user equipment (UE) may use multiple transmissions associated with a random access procedure to refine a beam that is used for subsequent portions of the access procedure. A UE may transmit a random access request to the base station and, in response thereto, the base station may transmit a control channel order to the UE. The control channel order may indicate that the UE is to transmit a modified random access request to the base station. The base station may monitor for the modified random access request using different beamforming parameters in order to determine a refined beam to be used for a subsequent transmission in the random access procedure. The base station may then use the refined beam to transmit a random access response to the UE, and complete the access procedure.
