  • Patent number: 11811706
    Abstract: A base station may transmit, to a wireless device, first downlink control information (DCI) via a physical downlink control channel (PDCCH) of an active bandwidth part (BWP), of the wireless device, during a discontinuous reception (DRX) active time. The base station may switch to a first downlink BWP as the active BWP during the DRX active time. The base station may start, in response to the switching, a BWP inactivity timer of the first downlink BWP. The base station may transmit a second DCI via a PDCCH of the first downlink BWP. The base station may receive a packet via a transmission interval of periodic resources indicated by a configured grant. The base station may restart the BWP inactivity timer at a time based on the transmission interval. The base station may switch, in response to an expiration of the BWP inactivity timer, to a second downlink BWP as the active BWP during the DRX active time. The base station may transmit a third DCI via a PDCCH of the second downlink BWP.

  • Patent number: 11812446
    Abstract: Methods, systems, and devices for wireless communication are described to indicate a transmission scheme configuration for a message and whether the message is a retransmission or new transmission. In a first example, a base station may configure a subset of one or more feedback process identifiers (IDs) for multicast messages. In such cases, if a grant includes a feedback process ID associated with one of the reserved IDs, the message scheduled by the grant may be a retransmission of a multicast message. In a second example, feedback process IDs may be dynamically allocated to multicast or unicast messages via a corresponding grant. A message may be identified as a new transmission or retransmission of a unicast message or multicast message based on a combination of an ID associated with the grant and a new data indicator (NDI) of the grant.

  • Patent number: 11792776
    Abstract: Time-division duplexing (TDD) in distributed communications systems, including distributed antenna systems (DASs) is disclosed. In one embodiment, a control circuit is provided and configured to control the TDD transmit mode of a DAS to control the allocation of time slots for uplink and downlink communications signal distribution in respective uplink path(s) and downlink path(s). The control circuit includes separate power detectors configured to detect either a transmit power level in a downlink path or a receive power level in an uplink path. If the transmit power detected in the downlink path is greater than receive power detected in the uplink path, the control circuit switches the TDD transmit mode to the downlink direction. In this manner, the control circuit does not have to control the TDD transmit mode based solely on detected power in the downlink path, where a directional coupler may leak uplink power in the downlink path.

  • Patent number: 11785642
    Abstract: A communication method performed by a User Equipment (UE) configured with a Discontinuous Reception (DRX) operation includes the UE initiating a Random Access (RA) procedure for Beam Failure Recovery (BFR) on a Special Cell (SpCell) after detecting a beam failure event on the SpCell, and transmitting a BFR Medium Access Control (MAC) Control Element (CE) on the SpCell. The BFR MAC CE indicates the beam failure event for the SpCell. The communication method further includes the UE determining a period of time as a DRX Active Time for the UE. The beginning of the period of time is determined by a first time at which the UE transmits the BFR MAC CE on the SpCell. The end of the period of time is determined by a second time at which the UE receives a BFR Response (BFRR) from the SpCell.

  • Patent number: 11757578
    Abstract: This disclosure provides systems, methods, and apparatuses for supporting network transmissions using unicast sidelink communications. A base station (BS) may transmit a set of encoded packets to a number of user equipment (UEs) and receive feedback messages from the UEs that indicate sets of decoded packets. Based on the feedback messages, the BS may transmit an updated set of encoded packets based on a difference between the set of encoded packets and the union of decoded packets. The BS may transmit an instruction to a first UE to transmit a unicast sidelink communication to a second UE that includes a set of missed packets that includes one or more decoded packets that were decoded by the first UE but were not decoded by the second UE. The first UE may transmit the unicast sidelink communication to the second UE.

  • Patent number: 11723050
    Abstract: Methods, systems, and devices for wireless communication are described. Generally, the described techniques provide for transmission configuration indication states that indicate quasi-collocation relationships. For example, a user equipment (UE) may transmit an uplink reference signal to a base station and receive, in response, a transmission configuration indication state from the base station that is based on the uplink reference signal. In some examples, the transmission configuration indication state may indicate a quasi-collocation relationship between the uplink reference signal and one or more reference signals associated with a downlink channel. In some implementations, the quasi-collocation relationship may be a spatial relationship between one or more antenna ports associated with the base station used to receive the uplink reference signal and one or more antenna ports used to transmit downlink data.
