  • Publication number: 20210051729
    Abstract: Wireless communication devices, systems, and methods related to mechanisms to implement improved RAR decoding performance and resource utilization efficiency in a RACH procedure. A PDCCH with common search space encodes a DCI with configuration information that schedules separate PDSCHs for different UEs/UE groups. When sending a RAR message, the PDCCH includes a DCI with a configuration field to signal multiple DMRS resources with corresponding PDSCH. Each sub-field of the configuration field may include one or multiple bits. When one bit per sub-field, the bit is a flag that when asserted leads the UE to blind decode the PDSCH associated with that DMRS resource. When multiple bits, it includes a flag field as well as one or more bits that include least significant bits of a UE identifier (or group identifier). The UE locates its identifier (or group identifier), and limits decoding to that PDSCH with corresponding DMRS resource.

  • Publication number: 20210050897
    Abstract: Methods, systems, and devices for wireless communications are described. A user equipment (UE) may refrain from transmitting channel state information (CSI) if the CSI is configured to be transmitted during an inactive discontinuous reception (DRX) duration. The UE may determine that the CSI is configured to be transmitted during the inactive DRX duration based on determining that some or all of the configured time slot for transmitting the CSI occurs while the UE is operating in the inactive DRX duration. The UE may transmit feedback information, such as an acknowledgement (ACK), whether or not the UE drops the CSI.

  • Publication number: 20210051651
    Abstract: Methods, systems, and devices for wireless communications are described. A user equipment (UE) may select a beam from a set of beams and transmit an indication of the selected beam in a media access control (MAC) control element to establish a communication link with a base station. In some cases, the UE may select the beam and indicate the selection based on identifying a beam failure and/or determining to perform a random access procedure. When transmitting the indication of the selected beam, the UE may obtain an uplink resource for the transmission based on an availability of the uplink resource. For example, if the uplink resource is available, the UE may transmit the indication of the selected beam multiplexed with an uplink transmission. Alternatively, if the uplink resource is unavailable, the UE may request uplink resources for transmitting the indication of the selected beam.

  • Publication number: 20210044342
    Abstract: Aspects are provided which enhance Mode 2 multi-TRP operation by allowing a UE to recover and reconfigure a failed PDCCH beam of a first TRP in a serving cell by using a second TRP which still has a working PDCCH in the same serving cell. If the first TRP undergoes beam failure but the second TRP in the same cell has an operational beam, the UE may send a beam failure indication indicating a new beam for the PDCCH of the first TRP. The base station comprising the second TRP may then reconfigure the PDCCH serving beams of the first TRP based on the beam failure indication. The reliability of a serving cell may thus be increased.

  • Publication number: 20210045054
    Abstract: In a legacy gNB (e.g., pre-Rel. 17 gNB), RC UEs with only 1 or 2 receive antennas may have a geographic coverage area for control data and traffic data that is smaller than their geographic coverage area for SSB with respect to certain legacy gNBs. By contrast, at least some new gNBs (e.g., Rel. 17+ gNBs) have the capability to provide uniform geographic coverage for RC UEs with respect to SSB, control data and traffic data. In an aspect of the disclosure, a particular class of UEs (such as RC UEs) is steered towards particular cells (e.g., Rel. 17+ gNBs) via one or more biased class-specific cell selection parameters included in system information from the cells.

  • Publication number: 20200413476
    Abstract: UEs may want to switch to the RRC idle state or to the RRC inactive state sooner than the expiration of the timer or without having to wait for the network to release the RRC connection. Allowing the UE to increase the rate at which it transitions to RRC idle state or RRC inactive state may allow the UE to reduce power consumption, as well as reduce signaling resources. The apparatus determines a preference between a transition to an RRC inactive state or to an RRC idle state when an RRC connection is released. The apparatus sends, to a base station, an RRC state preference indication of the preference for transitioning upon release of the RRC connection from the RRC connected state to one of the RRC inactive state or to the RRC idle state.

  • Patent number: 10880867
    Abstract: Various aspects directed towards performing a random access procedure are disclosed. In one example, a parameter is identified from a plurality of parameters, and an uplink (UL) resource associated with a random access procedure is selected based on a value associated with the parameter. A random access procedure communication is then transmitted via the selected UL resource. In another example, different parameters are supported by a scheduling entity such that each of the parameters has a corresponding plurality of different potential values. Here, the scheduling entity enables a scheduled entity to select an UL resource to perform a random access procedure based on a value corresponding to a particular one of the parameters. A random access procedure communication is then received from the scheduled entity via the UL resource.

  • Publication number: 20200396685
    Abstract: A user equipment (UE) may provide feedback regarding beam pairs used for wake-up signal (WUS) transmissions via uplink resources configured for WUS-based beam management feedback. A correspondence between WUSs and uplink resources for feedback may be semi-statically configured via radio resource control (RRC) signaling, may be dynamically indicated by each WUS, etc. In some examples, uplink resources for different UEs may be distinctive (e.g., UE-specific). In some cases, each beam used to transmit the wake-up message (e.g., each WUS) may have separate uplink resources, or all beams may share the same uplink resource (e.g., or some combination of uplink resources). As such, the UE and base station may identify one or more beams of sufficient quality (e.g., for control channel transmissions during a discontinuous reception (DRX) on-duration) based on the feedback (e.g., beam report) conveyed by the UE via the configured uplink resources for WUS-based fast beam management techniques.
