Abstract: Methods and systems are disclosed for a UE to perform measurements of measurement resources transmitted by a network when the UE is configured with multiple concurrent measurement gap patterns (MGPs). The measurement resources may be carried on multiple carrier frequencies. The UE may receive measurement resource configuration parameters identifying time and frequency locations of the measurement resources transmitted on the multiple carrier frequencies. The UE may receive measurement gap configuration parameters for multiple concurrent MGPs specifying measurement intervals that may be used to perform the measurements. The UE may determine a linkage between the measurement resources on a carrier frequency and one of the concurrent MGPs so that the UE may independently measure the measurement resources received on the multiple carrier frequencies using their respectively linked MGPs. The linkage may be made through information elements in the measurement resource configuration parameters or the measurement gap configuration parameters containing the MGP.

Abstract: Configuring channel state information reference signal (CSI-RS) reporting at a network may include encoding a channel state information (CSI) reporting configuration communication for transmission to a user equipment (UE) that is in connected mode with both a first transmission and reception point (TRP) and a second TRP. The CSI reporting configuration may include a first group of CMR (Channel Measurement Resource) resources for the first TRP, and a second group of CMR resources for the second TRP. A CSI measurement communication received from the UE, may be measurements based on the CSI-RS reporting configuration communication. Based on the CSI measurement communication, one or more downlink data transmissions may be scheduled.

Abstract: Systems and methods for beam failure recovery (BFR) are disclosed herein. A user equipment (UE) receives downlink (DL) reference signal (s) on corresponding beam (s) from a base station. The UE performs beam failure detection (BFD) on such beams used for user data to determine whether a beam failure has occurred, and candidate beam detection (CBD) on such beams not used for user data to identify candidate beams for recovering from the beam failure. The BFD and the CBD are based on both uplink (UL) channel performance considerations and DL channel performance considerations, as determined using the DL reference signal (s), such that a beam failure may be determined in the UL, the DL, or both, and a candidate beam may be identified for UL, DL, or both. The UE sends a beam failure recovery request BFRQ with this information to the base station, and the system changes beams accordingly.

Abstract: In sidelink carrier aggregation, a first user equipment (UE) transmits data packets to a second UE using a plurality of carriers. The second UE transmits Hybrid Automatic Repeat Request (HARQ) ACK/NACK information for the data packets to the first UE via one or more Physical Sidelink Feedback Channels (PSFCHs). The aggregated carriers may be constrained to have the same PSFCH configuration, or not. Resource selection for PSSCH transmission may be performed by considering scheduled PSFCH so as to conform to transmit capability limitations and/or a half-duplex limitation of the first UE and/or the second UE. The PSFCH may be transmitted on a single carrier of said plurality, but include joint HARQ feedback for each of the carriers. Furthermore, HARQ feedback may be transmitted on a Physical Sidelink Shared Channel (PSSCHs), being signaled by the receive UE (i.e., the UE that transmits the feedback) via sidelink control information (SCI).

Abstract: Aspects are described for a user equipment (UE) comprising a transceiver configured to enable wireless communication with a first transmission/reception point (TRP) and a second TRP and a processor communicatively coupled to the transceiver. The UE is in a multi-TRP mode. The processor is configured to perform a first beam failure detection (BFD) procedure for the first TRP and a second BFD procedure for the second TRP. The processor is further configured to perform a first beam failure recovery (BFR) procedure for the first TRP responsive to a result of the first BFD procedure and a second BFR for the second TRP responsive to a result of the second BFD procedure. The processor is further configured to receive a configuration message, a BFD configuration, and a BFR configuration. The UE switches to a single-TRP mode upon receiving the configuration message. The processor is further configured to update the first BFD procedure based on the BFD configuration and update the first BFR procedure based on the BFR configuration. Finally, the processor is configured to perform the updated first BFD procedure and the updated first BFR procedure for the first TRP responsive to a result of the updated first BFD procedure.

Abstract: A user equipment (UE) is configured to determine to perform a sounding reference signal (SRS) transmission with an antenna port switch operation, wherein the SRS transmission with the antenna port switch operation is performed during an SRS transmission occasion comprising one or more symbols of a slot and apply one or more scheduling restriction rules corresponding to the SRS transmission with the antenna port switch to provide one or more scheduling restrictions for the UE, wherein the scheduling restrictions cause the UE to omit performing at least one of transmission operations or reception operations during one or more symbols of the slot or one or more symbols of an adjacent slot.

Abstract: To accommodate a mix of high frequency carriers and lower frequency carriers, a protocol stack may include a radio link control (RLC) entity that allows configuration of status reporting control parameters on per carrier, or per subcarrier spacing. Alternatively, a protocol stack may include two RLC entities, one for handling high frequency carriers, and another for handling lower frequency carriers. High frequency carriers and lower frequency carriers may be distinguished based on a frequency threshold. Furthermore, a user equipment may transmit to the network an indication of its L2 buffer size. The network may configure the UE and/or control scheduling, to ensure the UE's L2 buffer does not overrun. Alternatively, the UE may indicate that it can support a percentage of a maximum buffer size. The network may configure the UE and/or control scheduling so that the UE's buffer occupancy does not exceed the percentage.
