  • Publication number: 20230309078
    Abstract: Methods, systems, and devices for wireless communications are described. Aspects include configuring a user equipment (UE) to receive control signals from a first transmission reception point (TRP) and a second TRP. A first TRP may transmit a control signal to the UE indicating resources for receiving a medium access control element (MAC-CE), where the control signal includes an indication that associates the MAC-CE with the first TRP. The first TRP may transmit the MAC-CE to the UE which may include a beam update indication for the first TRP. The UE may transmit an acknowledgement to the first TRP based on receiving the MAC-CE. The UE may also transmit an acknowledgment to the second TRP indicating that it has received a beam update indication from the first TRP. In some cases, the first TRP may send a MAC-CE signal to the UE including beam update information for the second TRP.

  • Patent number: 11770221
    Abstract: Methods, systems, and devices for time domain single carrier (SC) waveform communications are described. A user equipment (UE) may generate an SC waveform by resampling (e.g., up-sampling) mapped information bits prior to insertion of a cyclic prefix (CP) or guard interval (GI). Performing resampling prior to CP/GI insertion allows for resource allocation flexibility and a base station may allocate resources for the SC waveform in accordance with this flexibility. For example, a base station may not be limited or restricted to a certain number of resources for SC waveform communications and may therefore determine a resource allocation for the UE based on the capability of the UE to perform resampling prior to CP/GI insertion. The resampling may be performed according to a set of parameters including a resampling ratio, which may be indicated to the UE via control signaling (e.g., from the base station).

  • Patent number: 11758514
    Abstract: Methods, systems, and devices for wireless communications are described. A communication device, which may be otherwise known as user equipment (UE) may support repetition of physical downlink control channels (PDCCH) and handling a combined PDCCH candidate associated with multiple search space sets. For example, a UE may combine a first PDCCH candidate corresponding to a first search space set and a second PDCCH candidate corresponding to a second search space set to form a combined PDCCH candidate. The UE may decode the combined PDCCH candidate based on one or more factors, for example, such as a blind decoding PDCCH candidate threshold. As a result, the UE may decode the combined PDCCH candidate in addition to decoding of individual PDCCH candidates, thereby providing increased flexibility for downlink control information (DCI) and improving the reliability of PDCCH.

  • Patent number: 11751152
    Abstract: In one aspect, an extended SSB (ESSB) is provided that includes more than four symbols to facilitate UE reception of SSBs. In this aspect, the base station configures an ESSB comprising an SSB including four symbols and an initial symbol preceding the SSB. The base station transmits and the UE receives at least a portion of the ESSB. The UE processes the ESSB. Thus, higher capacity UEs can benefit from additional coding gain in the initial symbol while lower capacity UEs can switch beams to receive back-to-back ESSBs. In another aspect, a UE performs additional behaviors to receive SSBs. In this aspect, the UE receives a first SSB using a reception beam, and the UE determines to maintain the reception beam for a second SSB or to switch the reception beam during a PSS symbol of the second SSB. Thus, lower capacity UEs can also receive back-to-back SSBs.

  • Patent number: 11751073
    Abstract: Methods, systems, and devices for wireless communications are described. In some systems, wireless devices operating in an unlicensed radio frequency spectrum band may perform directional listen-before-talk (LBT) procedures to gain access to a channel. In a beam-shrinking scheme for directional LBT, a wireless device may start an LBT procedure using a first beam (e.g., a wide beam). If the clear channel assessment (CCA) fails for the first beam (e.g., due to directional interference), the device may switch the LBT procedure to a second beam (e.g., a narrower beam). Depending on the direction of the interference source, the second beam may result in a successful LBT procedure. In a beam sweeping scheme for directional LBT, a wireless device may perform concurrent LBT over multiple narrow beams. If any beam of the set of beams detects frequent or continuous interference, the device may drop that beam from the concurrent LBT procedure.

  • Patent number: 11751174
    Abstract: Methods, systems, and devices for signaling for configuring downlink transmissions are described. A user equipment (UE) may receive a configuration message from a base station indicating that a control resource set (CORESET) for a downlink control channel is associated with a set of transmission configuration indicator (TCI) states. The UE may subsequently receive a control message from the base station activating one or more of the TCI states. The UE may decode the downlink control channel based on the configuration message and the one or more activated TCI states. The UE may identify one or more TCI states (e.g., associated with the CORESET) to apply to a reception of a physical downlink shared channel (PDSCH) transmission. The UE may determine to apply one or more of the TCI states activated by the control message. The UE may determine to apply one or more different TCI states.
