Abstract: Methods and apparatuses are provided in a wireless communication system. Packet data convergence protocol (PDCP) configuration information that configures a PDCP entity of the terminal to use an uplink data compression (UDC) is received from a base station. The PDCP entity generates a UDC header and a UDC data block, based on the PDCP configuration information. The PDCP entity ciphers the UDC header and the UDC data block. The PDCP entity generates PDCP data including a PDCP header, the ciphered UDC header and the ciphered UDC data block. The generated PDCP data is transmitted to the base station. A header compression is not configured in case that the UDC is configured.

Abstract: User equipment to transmit signals (e.g., concurrently) using multiple SIMs. If the user equipment determines to perform transmission power back-off due to operating using the multiple SIMs (MuSIM operation), the user equipment sends an indication to each network corresponding to each SIM that it is performing the power back-off. If a network supports MuSIM operation, then the user equipment sends an indication that it is performing the power back-off due to MuSIM operation (e.g., an MuSIM Maximum Power Reduction (M-MPR) indication). For such a network, it is assumed that the M-MPR indication would be standardized under an applicable specification. If a network does not support MuSIM operation (e.g., a legacy network), then the user equipment leverages a legacy power back-off indication (e.g., a Power Management Maximum Power Reduction (P-MPR) indication) to indicate to the network that it is performing a power back-off.

Abstract: A wake-up signal (WUS) network (separate from a cellular network) includes WUS nodes that broadcast WUSs targeting WUS receivers of user equipment (UE). The WUSs may have low frequencies, such as within a television whitespace spectrum. When the cellular network determines that a UE should enter a power saving mode, or when a cellular receiver of the UE enters an idle state, the cellular network may request resources for the UE from a WUS node and activate a WUS receiver of the UE. When the cellular network has data to send to the UE or a threshold time has expired, the cellular network may request a WUS from the WUS network, which broadcasts the WUS that may be received by the UE. If the UE has data to transmit to the cellular network, the cellular network may request that the WUS node stop providing resources to the UE.

Abstract: A base station may send an indication of frequency subranges supported by the base station to user equipment, which may respond with an indication of the frequency subranges that are also supported by the user equipment. Additionally, a Spectrum Access System (SAS) controller, using environmental sensing capability sensors, may determine whether non-federal networks are disposed in a coverage area of a base station and neighboring coverage areas. If so, then the SAS may indicate to the base station to send an indication to user equipment in the coverage area to operate using a default power mode. Otherwise, the SAS may indicate to the base station to send an indication to the user equipment to operate using a lower power mode. Moreover, a base station may indicate a regulatory requirement to user equipment using network signaling value of multiple network signaling values corresponding to multiple regulatory requirements of multiple geographical regions.

Abstract: Embodiments disclosed herein relate to techniques for measuring and/or detecting a signal-to-interference ratio (SIR) of a received signal at a user equipment (UE). The received signal may include a desired signal, co-channel interference, adjacent channel interference, and an in-band blocker. The UE may filter (e.g., remove) the various interferences and in-band blocker. The UE may determine or measure a power (or Received Signal Strength Indicator (RSSI)) of the desired signal and a power (or RSSI) of the co-channel interference separately because the desired signal and the co-channel interference overlap in frequency. To do so, the UE may determine a total power of the received signal including the desired signal and co-channel interference. The UE may receive the desired signal again while an uplink transmission is deactivated (and thus without the interference). The UE may then calculate the SIR based on the total power and the power of the desired signal.
