Abstract:
Methods, systems, and devices for wireless communications are described that provide for a wireless device with dual subscriptions to prioritize a subscriber. A user equipment (UE) may configure a first channel for a first subscription and a second channel for a second subscription. The UE may determine one or more slots for the first subscription for communicating in a first direction and for the second subscription for communicating in a second direction, where the first and second directions are different. The UE may prioritize communications of the first subscription according to the determined slots. The prioritizing may be based on the direction, whether the communications are scheduled or configured, or whether the slot includes a monitoring occasion. The UE may communicate in the first direction according to the first subscription.
Abstract:
Aspects described herein relate to methods for TDM based co-existence of V2X technologies. A method may comprise receiving a time division multiplexed configuration that is determined based on a distribution of a plurality of technologies in a communication system, the distribution corresponding to a traffic load of each technology and transmitting in accordance with channel access methods of one of the plurality of technologies during a resource allocated according to the received TDM configuration. In an aspect, each of the plurality of technologies operate in accordance with channel access methods defined for each technology.
Abstract:
Improvements may be made for the congestion control considering different technologies, types of radio resources, and priorities of different packets. The apparatus may be a User Equipment, UE. The UE determines a channel busy ratio (CBR). The UE further determines one or more channel resource utilization limits based on the CBR, wherein each channel resource utilization limit of the one or more channel resource utilization limits corresponds to a respective packet priority. The UE controls transmission of a plurality of packets based on the one or more channel resource utilization limits, each packet of the plurality of packets being associated with a respective packet priority.
Abstract:
Techniques for adjusting a contention window (CW) for transmissions in a shared radio frequency spectrum band may include identifying a number of nodes attempting to transmit using a channel of a shared radio frequency spectrum band and determining a target CW based on the number of nodes attempting to transmit. A new CW value may then be determined based on a prior CW value and the target CW value, and a listen-before-talk (LBT) procedure (e.g., a clear channel assessment (CCA)) to access the channel of the shared radio frequency spectrum band may be performed to access the channel.
Abstract:
Certain aspects are directed to a method for wireless communication by a first base station. The method generally includes: assessing expected interference from a second base station to uplink communications on at least a portion of a first slot, the at least the portion of the first slot being configured for downlink; determining whether to convert the configuration of the at least the portion of the first slot from the downlink to uplink based on the assessment of the expected interference; and receiving signaling from a user-equipment (UE) via the at least the portion of the first slot in accordance with the determination.
Abstract:
The present disclosure relates to methods and devices for wireless communication including an apparatus, e.g., a user equipment (UE) and/or base station. In one aspect, the apparatus may configure a frame structure including a plurality of slots in a subframe, the plurality of slots including at least one of one or more downlink slots, one or more uplink slots, or one or more flexible slots, each of the one or more flexible slots including multiple subband resources. The apparatus may also signal configuration information of the frame structure including the plurality of slots. Additionally, the apparatus may communicate data via the frame structure including the plurality of slots.
Abstract:
Wireless communications systems and methods related to reducing user equipment (UE)-to-UE cross-link interference are provided. A user equipment (UE) may receive from a base station (BS), a time-division-duplexing (TDD) pattern. The EE may establish a guard band on uplink resources from resources specified in the TDD pattern. Alternatively, the UE may reduce power to uplink resources from the resources specified in the TDD pattern. The UE transmits the resources using a carrier and as specified in the TDD pattern.
Abstract:
Methods, systems, and devices for beamforming in environments with angular constraints are described. A wireless device such as a user equipment (UE) or base station may configure beam parameters based on a sensitivity level of a neighboring wireless device (e.g., a satellite). The configuration of beam parameters may be based on an interference power profile (e.g., threshold(s) indicated by an interference power profile). The interference power profile may specify a mask, which may indicate allowed or unintended directions for transmission or a transmission power mask. A beamformed transmission may be in accordance with the configured beam parameters, which may result in a reduced transmission power in one or more directions, compliance with total power limits, peak power limits, or energy radiated over a period of time, or any combination thereof.
Abstract:
Certain aspects of the present disclosure provide techniques for interference mitigation. An exemplary method performed by a base station generally includes determining, based on a location of another base station and information regarding the other base station, that the other base station is likely to experience interference while receiving an uplink transmission due to a downlink transmission by the base station and forming a null in a beam of the downlink transmission in a direction matching the location of the other base station.
Abstract:
Apparatus and methods for long term evolution (LTE) licensed-assisted access (LAA) communications at a user equipment (UE) are described herein. In an aspect, an example method includes a user equipment (UE) receiving a radio resource control (RRC) message from an eNB and searching for a discovery reference signal (DRS) associated with a secondary cell (Scell) of the eNB based at least on the information received in the RRC message. The example method further includes transmitting on the channel detected during the search.
