  • Publication number: 20210329636
    Abstract: Aspects of the present disclosure provide for the pairing of an inter-band carrier with a time division duplex (TDD) carrier. If the paired band is a frequency division duplex (FDD) band, then base stations and mobile devices may transmit and receive additional thin control channels on FDD carriers to enable full duplex operations. If the paired band is a TDD band, then a conjugate or inverse carrier may be used such that full duplex, or a close approximation thereto, is achieved. With the introduction of a paired channel and fast control channels, rapid uplink/downlink switching may be achieved for TDD carriers efficiently and effectively. Other aspects, embodiments, and features are also claimed and described.

  • Publication number: 20210328843
    Abstract: Orthogonal frequency-division multiplexing (OFDM) numerologies that maintain symbol boundary alignment while distributing excess cyclic prefixes (CPs) among OFDM symbols. Communication is established using a first sub-carrier spacing (SCS) and a first OFDM numerology, such as an exemplary numerology that distributes excess CP duration among a set of symbols that occupy a time interval within or equal to a corresponding time interval of a symbol of a second OFDM numerology with a second lower SCS. The first SCS may be, e.g., 960 kHz. The second SCS may be, e.g., 120 kHz. Another exemplary OFDM numerology described herein distributes the excess CP as prefix and postfix portions to one of the symbols, such as the first symbol of a set. Communication then proceeds using the first OFDM numerology at the first SCS and, in illustrative examples, using the second OFDM numerology at the second SCS or other OFDM numerologies at other SCSs.

  • Publication number: 20210329691
    Abstract: Methods, systems, and devices for wireless communications are described in which a base station and a user equipment (UE) may perform beam refinement within a random access procedure. A UE may transmit a random access request to the base station and, in response thereto, the base station may transmit a control channel order to the UE that indicates to transmit a modified random access request. Resources for the modified random access request may be determined based on the random access request, the control channel order, configured resources, or combinations thereof. The base station may monitor for the modified random access request using different beamforming parameters and determine a refined beam for a subsequent transmission in the random access procedure. The base station may use the refined beam to transmit a random access response to the UE, and complete the access procedure.

  • Patent number: 11153829
    Abstract: Methods, systems, and devices for wireless communications are described that provide for managing transmissions using multiple component carriers (CCs) in which transmissions using one or more of the CCs may span less than a full transmission time of a slot or other transmission time interval. A UE may signal a capability to transmit such transmissions, and one or more capabilities related to carrier aggregation that may be used by a base station for scheduling of transmissions on different CCs. In the event that overlapping transmissions on two or more CCs exceed a maximum power threshold, various techniques for dropping at least a portion of one or more transmissions of one or more CCs are described.

  • Patent number: 11153866
    Abstract: Methods, systems, and devices for wireless communication are described for shortened transmission time interval (TTI) configuration based on user equipment (UE) capabilities. A UE may determine, for each of one or more supported bands or band combinations, a capability of the UE to process transmissions having a first transmission time interval (TTI) duration and a second TTI duration, the first TTI duration being shorter than the second TTI duration. The UE may transmit to a base station an indicator representing the capability for the each of the one or more supported bands or band combinations. The base station may receive the indicator, schedule a component carrier within a frequency band of a first supported band combination of the one or more supported band combinations based at least in part on the received indicator, and transmit information within the frequency band of the component carrier based on the scheduling.
