  • Publication number: 20200296677
    Abstract: A user equipment (UE) may improve capability parameter signaling and handling phase discontinuity according to an absence or presence of certain capability parameters within a capability message. In one aspect, when a power amplifier capability parameter is present within a capability message, this may be treated as if a phase discontinuity capability parameter is absent from the capability message. Alternatively, in another aspect, when a power amplifier capability parameter is absent within a capability message, this may be handled as if a phase discontinuity capability parameter is present within a capability message. Thus, for band combinations that include intra-band carrier aggregation with a single band, UE may include a power amplifier capability parameter or a phase discontinuity capability parameter. For all other band combinations, the UE may refrain from including the power amplifier capability parameter and may include a phase discontinuity capability parameter in the capability message.

  • Patent number: 10779312
    Abstract: Described techniques provide for communications using multiple different transmission time intervals (TTIs) while in a configured DRX mode that allows efficient scheduling and allocation of resources, and relatively efficient power usage at a user equipment (UE). In some cases, two or more available TTIs for transmissions between a base station and a UE may be identified, and a DRX cycle configured based at least in part on the available TTIs. During monitoring periods of a configured DRX cycle for a first TTI, the UE may be configured to monitor for control signal transmissions associated with a different TTI duration. In some cases, resources for a shorter TTI may be allocated using a two-stage grant. In some cases, multiple component carriers may be configured for one or more different TTIs, and one component carrier may be used to cross schedule resources on other component carriers.

  • Patent number: 10764833
    Abstract: Some wireless communications systems may support mobile broadband (MBB) communications and low latency communications. To facilitate low latency communications, a base station may assign resources allocated for an MBB transmission for a low latency transmission. As described herein, to limit interference between an MBB transmission and a low latency transmission while maximizing the chances that the MBB transmission is received, an MBB user equipment (UE) may be configured to adjust a transmit power for the MBB transmission to limit the impact on a low latency transmission without preempting the MBB transmission. However, if the MBB UE is unable to adjust the transmit power for the MBB transmission prior to the MBB transmission, the MBB UE may determine whether to drop a portion of the MBB transmission on the resources assigned for the low latency transmission (e.g., based on whether a received power of the MBB transmission exceeds a threshold).

  • Publication number: 20200275504
    Abstract: Methods, systems, and devices for wireless communication are described. Generally, the described techniques provide for efficiently performing dynamic power control with minimal complexity in a dual connectivity mode. In particular, a user equipment (UE) may determine the reserved power (or maximum available power) for uplink transmissions on one or more cells in one cell group to a base station based on the total power available to the UE and the minimum reserved power for uplink transmissions on one or more cells in another cell group. Once the UE determines the reserved power for conflicting uplink transmissions on one or more cells in a cell group, the UE may allocate the reserved power to each uplink transmission on the one or more cells in the cell group (e.g., based on a priority of each of the uplink transmissions).

  • Publication number: 20200275476
    Abstract: Methods, systems, and devices for wireless communications provide for feedback transmissions using an uplink shared channel. A user equipment (UE) may transmit feedback to a base station using physical uplink shared channel (PUSCH) resources. The base station may transmit an uplink grant to the UE indicating a set of resources for uplink data transmissions. The base station may subsequently transmit a downlink grant for the UE. Based on monitoring resources indicated by the downlink grant, the UE may generate feedback indicating the success of receiving or decoding the PDSCH transmission. The UE may transmit the feedback to the base station on the PUSCH resources. In some cases, the UE may transmit both the feedback for the PDSCH transmission received after the uplink grant and for a second PDSCH transmission received prior to the uplink grant using PUSCH resources.

  • Patent number: 10757718
    Abstract: Methods, systems, and devices for wireless communication are described. Some wireless communications systems support mobile broadband (MBB) communications and low latency communications. To accommodate low latency communications, a base station may identify resources allocated for MBB communications, and the base station may reassign (or puncture) these resources for low latency communications. The base station may transmit an indication of the reassigned (or punctured) resources to one or more user equipment (UEs). The base station may transmit an indication of the reassigned resources in a transmission time interval (TTI) that is subsequent to a TTI reassigned (or punctured) for low latency communications (e.g., a post indication). The base station may transmit the post indication in a retransmission grant of a physical downlink control channel (PDCCH) or in downlink control information (DCI) of a PDCCH.

  • Publication number: 20200267700
    Abstract: Methods, systems, and devices for wireless communications at a user equipment (UE) are described. Techniques are described herein for performing out-of-order processing. The UE may receive a first downlink channel at a first time and a second downlink channel at a second time. The UE may determine that a priority of the second downlink channel is different (e.g., higher) than a priority of the first downlink channel. The UE may determine that a first uplink transmission associated with the first downlink channel is to be transmitted after a second uplink transmission associated with the second channel based on the different priorities. The UE may set one or more operations based on these determinations. In some cases, the UE may suspend processing the of the first downlink channel to process the second downlink channel.

  • Publication number: 20200267756
    Abstract: This disclosure provides methods, devices, and systems for physical uplink shared channel (PUSCH) repetition based on support signaling, such as an uplink grant that includes a time domain resource assignment for transmitting one or more data repetitions that may cross a slot boundary. The UE may identify directions (for example, uplink, downlink, flexible) for one or more symbols spanning a transmission duration of the time domain resource assignment. The directions may be determined using a dynamic slot format indication (SFI), or semi-static SFIs may be used as a fallback (when dynamic slot format indications do not meet a target reliability). The uplink grant may include an indication of which symbol directions can be used for the one or more data repetitions. A subset of the one or more symbols for scheduling the one or more data repetitions may be determined based on the identified directions.

  • Publication number: 20200260478
    Abstract: Methods, systems, and devices for wireless communication are described. Generally, the described techniques provide for efficiently determining whether to transmit an uplink transmission scheduled by a semi-static grant or a dynamic uplink transmission scheduled by a dynamic grant when the dynamic uplink transmission conflicts with the uplink transmission scheduled by the semi-static grant. In particular, if a user equipment (UE) determines that a dynamic grant is received within a threshold time before an uplink transmission scheduled by a semi-static grant, the UE may transmit the uplink transmission scheduled by the semi-static grant and refrain from transmitting the dynamic transmission. Alternatively, if the UE determines that a dynamic grant is received in advance of a threshold time before an uplink transmission scheduled by a semi-static grant, the UE may transmit the dynamic transmission and refrain from transmitting the uplink transmission scheduled by the semi-static grant.

  • Publication number: 20200260499
    Abstract: Methods, systems, and devices for wireless communications are described. A user equipment (UE) may use easily detectable transmission parameters to infer difficult-to-detect parameters for communications with a base station. For example, the base station may provide the UE with multiple sets of transmission parameters, and the UE 115 may choose from among these sets of transmission parameters for the communications. In some cases, the UE may be configured with a reference set of transmission parameters, receive one or more transmission parameters that are different relative to the reference set of transmission parameters, and then determine to use the different transmission parameters for the communications. Additionally or alternatively, the multiple sets of transmission parameters may be specified for a certain uplink message (e.g., random access channel messages), where the UE selects the transmission parameter set based on one or more characteristics of the uplink message.

  • Patent number: 10721756
    Abstract: A method and apparatus for enabling repetitive transmissions for low latency systems is disclosed. For example, a base station may determine whether an uplink coverage parameter for a UE communicating with the network entity on an uplink communication channel satisfies an uplink coverage threshold, and transmit an activation message for repetition-based uplink communications to the UE based on a determination that the uplink coverage parameter for the UE communicating with the network entity on the uplink communication channel satisfies the uplink coverage threshold. Further, a UE may receive an activation message for repetition-based uplink communications from a network entity, and perform repetitive transmissions on the uplink communication channel for the duration indicated by the one or more transmission parameters in the activation message, the repetitive transmissions being configured based on the uplink sTTI pattern.
