Abstract: Techniques discussed herein facilitate Base Station (BS) enhancements to measurement by a RRC Connected mode User Equipment (UE) for configuration of Carrier Aggregation (CA) and/or Dual Connectivity (DC). One example embodiment comprises a BS device comprising a processor configured to perform operations comprising: receiving a UE Assistance Information message comprising a measurement request; transmitting a first RRCReconfiguration message comprising a measConfig IE; receiving a MeasurementReport message from a UE that indicates one or more measurements on one or more sets of frequencies, wherein the one or more sets of frequencies comprise a set of serving frequencies for one of a serving cell or the neighboring cell and a set of non-serving frequencies for the UE, wherein the set of non-serving frequencies are associated with the neighboring cell; and transmitting a second RRCReconfiguration message that configures the UE with at least one set of the one or more sets of frequencies.

Abstract: A wireless user equipment (UE) device may transmit a random access preamble to a base station, using a physical resource on an uplink signal. After failing to receive an initial transmission of a response message from the base station (BS), the UE device may monitor for one or more retransmissions of the response message. Each of the retransmission may include a corresponding transmission number. As an alternative, each of the retransmissions may be at least partially scrambled using a corresponding Radio Network Temporary Identifier (RNTI). As another alternative, a window for monitoring and RNTI calculation may be extended to include the one or more retransmissions. The successive retransmissions may include the same set of UE-specific payloads, or, a decreasing set of payloads over time as UE devices acknowledge successful receipt of their respective payloads.

Abstract: A method for power saving, comprising: establishing a radio resource control (RRC) connection with a wireless device, transmitting, to the wireless device, configuration information indicating a discontinuous reception (DRX) cycle time, a DRX on time period, and an offset time, transmitting an enhanced wake-up signal (EWUS) monitoring occasion for a DRX cycle, the EWUS monitoring occasion based on the offset time and the DRX on time period, determining that the wireless device can skip monitoring one or more future EWUS monitoring occasions, transmitting, during a first DRX cycle, a EWUS for the wireless device during the EWUS monitoring occasion associated with the first DRX cycle, the EWUS indicating that the wireless device can skip the one or more future EWUS monitoring occasions, and skipping transmitting the EWUS to the wireless device during the one or more future EWUS monitoring occasions.

Abstract: Systems and methods for using a relay user equipment (UE) to transport data of interest received from a first remote UE to a second remote UE on a UE to UE relay within a wireless communication system are discussed herein. These methods may be performed at Layer 2 of a protocol stack of the wireless communication system. Data packets sent on the UE to UE relay may include an adaptation header including routing information (e.g., Layer 2 addresses, a bearer-specific index, etc.) for the UE to UE relay. An adaptation layer may accordingly be provided within Layer 2 to decode these adaptation headers. In some cases, a per-bearer approach may be used to map between individual direct bearers of a hop by hop path configuration of the UE to UE relay. Embodiments eschewing the adaptation header and instead using logical channel identifiers (LCIDs) to make routing indications are also described.

Abstract: Some embodiments of this disclosure include apparatuses and methods for implementing mechanisms for exchanging a searcher number between an electronic device (for example, a UE) and a network for cell detection and measurement. For example, some embodiments relate to an electronic device including a transceiver and a processor communicatively coupled to the transceiver. The processor determines a searcher number associated with the electronic device. The searcher number is greater than two. The processor further transmits, using the transceiver, a signal to the network, where the signal includes an indication of the searcher number.

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.

Abstract: Apparatuses, systems, and methods for multi-TRP by a UE, including out of order delivery of PDSCH, PUSCH, and/or DL ACK/NACK. The UE may receive, from a base station, a configuration that may include multiple control resource set (CORESET) pools and each CORESET pool may be associated with an index value. The UE may determine that at least two DCIs of the multiple DCIs end at a common symbol and determine, based on one or more predetermined rules, when the UE may be scheduled to receive PDSCHs, transmit PUSCHs, and/or transmit ACK/NACKs from CORESETs associated with the at least two DCIs.
