    Abstract: A user equipment (UE) is configured with multi-transmission and reception point (multi-TRP) operation. The UE groups capabilities of handling two overlapping physical downlink shared channel (PDSCH) transmissions into a plurality of groups, determining a UE capability of handling two overlapping PDSCH transmissions based on the plurality of groups and transmits the UE capability to a next generation nodeB (gNB) of a 5G new radio (NR) wireless network. The UE also determines if a demodulation reference signal (DMRS) of a physical downlink shared channel (PDSCH) transmission collides with a cell-specific reference signal (CRS) of a long term evolution (LTE) transmission and determines if the CRS originated from a same multi-transmission/reception point (TRP) as the DMRS.

    Abstract: A user equipment (UE) is configured to perform channel estimation. The UE operates in a current channel estimation mode comprising either one of a first mode or a second mode, wherein the first mode comprises receiving first reference signals (RS) having a first RS overhead and wherein the second mode comprises receiving second reference signals (RS) having a second RS overhead, receives a network indication to switch from the current channel estimation mode to a new channel estimation mode comprising the other one of the first mode or second mode, transmits an acknowledgment to the network that the network indication was received and switches from the current channel estimation mode to the new channel estimation mode in accordance with the network indication.

    Abstract: A base station of a network configures a first search space having a first search space identification (SearchSpaceId) in a special cell (SpCell) and a second search space having a second search space identification (SearchSpaceId) in a secondary cell (SCell) for monitoring control signaling that schedules operations on the SpCell. The base station transmits a radio resource control (RRC) configuration to a user equipment (UE) including the first SSID and the second SSID, wherein the RRC configuration configures the UE to monitor the first search space having the first SSID for scheduling of a first type of control signaling and the second search space having the second SSID for scheduling of a second type of control signaling.

    Abstract: A user equipment (UE) is configured to determine that half-duplex frequency division duplex (HD-FDD) is enabled by a network with which the UE is communicating, identify a collision between a cell-specific downlink reception and a cell-specific uplink transmission and implement a HD-FDD collision handling technique. A UE may also be configured to determine that half-duplex frequency division duplex (HD-FDD) is enabled by a network with which the UE is communicating, perform a first cell-specific uplink transmission at a first time and perform a first cell-specific downlink reception at a second time, wherein a guard period represents a time duration between the first time and the second time during which the UE is not to perform a second different cell-specific uplink transmission or a second different cell-specific downlink reception.
