  • Publication number: 20220312471
    Abstract: Methods, systems, and devices for wireless communications are described in which a base station operating in full-duplex mode may provide for reception of one or more higher priority transmissions using at least partially overlapping time-frequency resources as used for transmission of lower priority communications. In order to mitigate self-interference at the base station, a transmission power used for the overlapping time-frequency resources may be reduced. The base station may provide an indication of a subset of resources that have a reduced transmission power, an amount of the power reduction for the subset of resources, or both.

  • Publication number: 20220304014
    Abstract: Aspects are provided which allow a user equipment (UE) to identify a low-bandwidth (low-BW) CORESET-0 and associated CSS based on reception bandwidth of the UE. The base station may configure different frequency and time-domain resources of the low-BW CORESET in order to optimize resource utilization of the low-BW CORESET-0, and the low-tier UE may identify these resources of CORESET-0 and CSS from the system configuration information received in a master information block (MIB). As a result, low tier UEs may operate in a same cell as legacy UEs without the need for the base station to transmit additional signaling to either legacy UEs or lower tier UEs for the UEs to receive their respective CORESET-0's and identify a physical downlink channel (PDCCH).

  • Publication number: 20220295567
    Abstract: Methods, systems, and devices for wireless communications are described. In a random access (RACH) procedure, a user equipment (UE) may transmit a first RACH message (e.g., RACH Message A (MsgA)) to a base station, which may include an indication of a modulation order, a maximum number of repetitions for RACH Message B (MsgB) data, or both. The base station may multiplex random access responses (RARs) for UEs into second RACH messages (e.g., RACH MsgBs) based on the indication(s) and may transmit these RACH MsgBs. The UE may receive and decode a downlink control information (DCI) portion of a RACH MsgB but may determine not to decode the data portion of the RACH MsgB if an indication in the DCI of the modulation order, the threshold number of repetitions, or both does not match the value reported by the UE. Otherwise, the UE may decode the full RACH MsgB.

  • Publication number: 20220295544
    Abstract: Methods, systems, and devices for wireless communications are described. A user equipment (UE) may receive, for a base station, a configuration message indicating a set of random access resources associated with monitoring by a relay node. The UE may transmit a random access message using the random access resources to the relay node and a timing advance associated with uplink data transmissions by the UE. The UE may then communicate with the base station via the relay node based on the random access message. In some examples, a UE may monitor for a relay reference signal from a relay node. The UE may determine a signal strength and a timing of the relay reference signal. The UE may determine whether an RSRP satisfies a threshold receive power, and may determine whether the timing of the relay reference signal is less than a timing threshold. The UE may transmit a downlink relay request to the base station to initiate relay communications.

  • Publication number: 20220287062
    Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a base station (BS) may identify a collision between a data transmission and a demodulation reference signal (DMRS) transmission in a full-duplex time-frequency resource. The BS may transmit, to a wireless communication device, an indication of a time-frequency mapping for a zero-power DMRS (ZP-DMRS) in the full-duplex time-frequency resource. The time-frequency mapping for the ZP-DMRS, and a time-frequency mapping in the full-duplex time-frequency resource for the DMRS transmission, may be a same time-frequency mapping. Numerous other aspects are provided.

  • Publication number: 20220286191
    Abstract: Methods, systems, and devices for wireless communications are described. A user equipment (UE) may communicate with a base station over a first bandwidth part (BWP) of a carrier. The UE may receive a beam failure recovery (BFR) configuration signal configuring a set of periodic channel state information reference signals (CSI-RSs) in the first BWP and a set of synchronization signals in a second BWP. The UE may measure the set of periodic CSI-RSs in the first BWP. The UE may set a beam for communicating with the base station over the first BWP based at least in part on the measuring. The UE may be a reduced bandwidth capability and support communicating with the base station using only one BWP.

  • Publication number: 20220287069
    Abstract: Methods, systems, and devices for wireless communications are described. A user equipment (UE) may receive a downlink control information (DCI) message from a base station that schedules multiple transport blocks (TBs) to be transmitted to the UE. Accordingly, the UE may determine a bundling configuration for grouping the multiple TBs into separate groups of TBs such that separate acknowledgment (ACK) feedback messages are transmitted by the UE for each group of TBs to indicate whether each of the TBs in each TB group was correctly received and decoded. In some cases, the UE may determine the bundling configuration based on radio resource control signaling from the base station, DCI signaling from the base station, relationships or equations or tables defined for the UE, or a combination thereof. Additionally, the UE may determine resource locations and timelines for transmitting the separate ACK feedback messages.
