Abstract: A wireless device receives indications of: a first scheduling request (SR) resource corresponding to first logical channel(s) having a first logical channel prioritization (LCP) mapping to first radio resources; and a second SR resource corresponding to second logical channel(s) having a second LCP mapping to second radio resources. A buffer status report (BSR) is triggered in response to data becoming available for the second logical channel(s). First uplink grant(s) indicating a first radio resource of the first radio resources is received. An SR for transmission of the BSR is triggered in response to the first radio resource not meeting the second LCP mapping configured for the second logical channel(s) that triggered the BSR. The SR is transmitted via the second SR resource selected based on the second logical channel(s) triggering the BSR. The BSR is transmitted via a second radio resource of the second radio resources.

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.

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.

Abstract: Various arrangements for using different air interfaces on adjacent frequency channels for side-link communications are presented. A first side-link channel may be split into a first bandwidth portion and the second bandwidth portion, in which the first bandwidth portion of the first side-link channel is directly adjacent to the second side-link channel. A first subcarrier spacing may be assigned to the first bandwidth portion of the first side-link channel. The second side-link channel may also use the first subcarrier spacing. A second subcarrier spacing may be assigned to the second bandwidth portion of the first side-link channel that differs from the first subcarrier spacing.

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.

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.
