  • Patent number: 10798704
    Abstract: Methods, systems, and devices for wireless communication are described. The described techniques provide for configuration and transmission of reference signals over aggregated mini-slots by modifying (e.g., extending) transmission time intervals (TTIs) or sharing reference signals across multiple mini-slots. The reference signals may be shared between multiple aggregated mini-slots and a reference signal pattern may be determined based on data payload allocation, modulation coding scheme (MCS), rank, or other factors of the aggregated mini-slots. Data payloads may be scheduled jointly or separately for each mini-slot and may be allocated across a set of aggregated mini-slots.

  • Patent number: 10764932
    Abstract: Methods, systems, and devices for wireless communications are described. One method may include receiving a beam switch message prior to initiating a physical random access channel (PRACH) procedure, monitoring for a response from a base station using a candidate beam during a random access response window, identifying a beam switch event occurring within the random access response window based on beam switch timing information indicated in the beam switch message, and performing a beam switch procedure based on an absence of a response from the base station during a portion of the random access response window and prior to the beam switch event.

  • Patent number: 10764775
    Abstract: Various techniques are proposed to enhance or expand the capabilities or usage of buffer status request (BSR) and scheduling request (SR) in new radio (NR) applications. In an implementation, techniques are proposed to extend the SR in long term evolution (LTE) baseline with additional information to help a base station (e.g., gNB) schedule faster and more efficiently. Moreover, a new BSR triggering condition is proposed to report new data based on particular events instead of being time-based. Modifications being proposed to both BSR and SR can be customized for different numerologies/transmission time intervals (TTIs). Modifications being proposed to SR can also be used to indicate a user equipment (UE) new beam selection after recovering from a beam failure.

  • Publication number: 20200267770
    Abstract: Methods, systems, and devices for wireless communication are described. In some wireless systems, a user equipment (UE) may access a network or cell using a random access (RACH) procedure. A base station may allocate dedicated RACH resources and common RACH resources for the UE to transmit a RACH preamble message on and may convey a configuration for the UE. In some cases, the UE may perform multiple transmissions of the RACH preamble message in the dedicated RACH resources, and based on the configuration may determine whether to perform a single or multiple transmissions of the RACH preamble message in the common RACH resources. The UE may transmit the messages using the same or different uplink transmit beams, and the base station may receive the messages using the same or different uplink reception beams. These multiple transmissions may reduce latency and improve reliability of the RACH procedure.

  • Patent number: 10750569
    Abstract: Methods, systems, and devices for wireless communication are described. A base station may transmit a UE-specific beam management parameter to a user equipment (UE) in a connected mode discontinuous reception (C-DRX) OFF state. The UE-specific beam management parameter may indicate a time interval for reception of downlink reference signals (RSs) prior to the beginning of a next C-DRX ON state. The UE may monitor for downlink RSs, and transmit an uplink measurement report during the C-DRX OFF state, which may indicate a reconfigured active beam pair for use during the next C-DRX ON duration. In some cases, the UE may transmit uplink RSs to the base station, and the base station may reconfigure an active beam pair based on the uplink RSs. The UE may monitor for control information (e.g., in a physical downlink control channel (PDCCH)) during the next C-DRX ON duration, using the reconfigured active beam pair.

  • Patent number: 10735078
    Abstract: Certain aspects of the present disclosure provide techniques and apparatus for operations with switching active bandwidth parts (BWPs), such as for radio link monitoring (RLM), beam failure recovery, random access, and/or other operations. As described herein, a UE may be configured with one or more sets of BWPs. The UE may determine/select the uplink and/or downlink BWP to use. For example, the UE can determine to use an active BWP or to switch to another BWP. The UE may use the BWP during operations, such as RLM, beam failure recovery, and/or random access, etc. for monitoring on the downlink and/or for transmitting on the uplink.

  • Patent number: 10736063
    Abstract: Methods, systems, and devices for wireless communication are described. A user equipment (UE) being served by a first cell may receive a synchronization signal (SS) block from the first cell. The UE may also receive an SS block from a second cell. The first cell may determine synchronization assistance information for the second cell and transmit the synchronization assistance information to the UE. The UE may use the synchronization assistance information to determine the index for the SS block from the second cell. For example, the synchronization assistance information may indicate that the UE is to use the index of the SS block from the first cell as the index for the SS block from the second cell. Once the index for the SS block from the second cell is determined, the UE may identify the subframe or slot timing used by the second cell and proceed with cell acquisition.

  • Publication number: 20200245198
    Abstract: This disclosure generally relates to systems, devices, apparatuses, products, and methods for wireless communication. A communication system may include a user equipment (UE) that receives a configuration for contention-free random access (CFRA) and a configuration for contention-based random access (CBRA). The UE determines a first random access resource. The first random access resource maps to one or more beams from a target base station. The UE determines a beam quality associated with the first random access resource. The UE initiates a random access request using the CFRA when the first random access resource is a contention-free resource, and the beam quality of the first random access resource is above a threshold beam quality. The UE initiates the random access request using the CBRA when the first random access resource is the contention-free resource, and the beam quality of the first random access resource is below the threshold beam quality.

  • Patent number: 10728897
    Abstract: Methods, systems, and devices for wireless communication are described. Uplink resources may be allocated for transmissions of beam recovery messages. For example, a user equipment (UE) communicating in a system that supports beamformed transmissions may receive a configuration for resources from a base station, where the resources may be used for beam recovery signaling. The UE may identify a beam failure on one or more active beams used to communicate with the base station, and the UE may transmit a beam recovery message to the base station. In such cases, the beam recovery message may be transmitted according to the configuration received from the base station such that the beam recovery message is transmitted using the beam recovery resources. In some cases, the configuration may be received at the UE via radio resource control (RRC) signaling or via a system information broadcast from the base station.
