  • Patent number: 11122594
    Abstract: Techniques for triggering multiple basic service sets (BSSs) to share resources for a coordinated transmission are described. One technique includes determining a first amount of data available to send in a first BSS and determining a second amount of data available to send in a second BSS. The first BSS and the second BSS form an overlapping BSS. An amount of resources in the first BSS that is available to share with the second BSS for a coordinated transmission from the first BSS and the second BSS is determined based on the first amount of data and the second amount of data. A frame that includes an indication of the amount of resources is generated and transmitted to at least one of the first BSS and the second BSS.

  • Patent number: 11122596
    Abstract: A user equipment (UE) may transmit a sounding reference signal (SRS) on a component carrier (CC) that is otherwise configured for downlink communications. Due to a carrier aggregation configuration or UE capability, the UE may need to retune certain components to transmit on the CC. If the SRS transmission, including the retuning time, collides with another transmission the UE may drop the SRS, drop the other transmission, or puncture the other transmission to facilitate the SRS transmission. The determination about a collision may depend on the retuning time, channel, or type of control information in the other transmission. In some cases, a UE may drop the other transmission if transmitting the SRS would prevent the UE from transmitting a demodulation reference signal, hybrid automatic repeat request (HARQ) feedback. In some cases, the determination may be based upon a prioritization and may also depend on a subsequent subframe.

  • Patent number: 11121828
    Abstract: New radio (NR) Uplink (UL) transmissions in an NR physical UL channel can be configured for a user equipment (UE) to communicate with a base station (e.g., gNB). The structures and mechanisms for configured these communications different from long term evolution (LTE) in NR specifications. A UE can generate a UL transmission with symbols on the NR physical channel including demodulation-reference signal (DM-RS) symbols and uplink control information (UCI) symbols. The UL transmissions comprise a DM-RS symbol located at each first symbol with variable lengths. The UE generates the UL transmission as an NR physical UL channel with about a 50% DM-RS overhead with a same or more DM-RS symbols than UCI symbols in a sequential pattern (e.g., an alternating pattern). The UE further maps HARQ-ACK feedback on a PUSCH based a frequency first operation that initiates following the DM-RS symbol located at the first symbol.
