Abstract: A user equipment (UE) is connected to a 5G New Radio (NR) network via a serving cell. The UE performs radio resource management (RRM) measurements on the serving cell, determines whether the UE satisfies power saving criteria for a first, second, or third mobility scenario while in a Radio Resource Control (RRC) idle state or RRC inactive state, wherein, when the UE is in the first or second mobility scenario, the UE performs RRM measurements with longer intervals relative to RRM measurements performed in a non-power-saving mode and wherein, when the UE is in the third scenario, the UE performs RRM measurements for neighbor cells with longer intervals relative to RRM measurements performed in a non-power-saving mode and determines a UE RRM configuration when the UE transitions from any of the power saving scenarios or the non-power-saving mode to any other power saving scenarios or the non-power-saving mode.

Abstract: A wake up signal scheme between a network and a user equipment (UE) operating in a Discontinuous Reception (DRX) state. The UE monitors a wake up signal (WUS) occasion to determine whether a WUS is received during the WUS occasion, when the WUS is received, determines whether the WUS identifies the UE, when the WUS is received and identifies the UE, monitors an OnDuration of a Discontinuous Reception (DRX) cycle corresponding to the WUS and when the WUS is not received or the WUS does not identify the UE, remains in a sleep state during the OnDuration corresponding to the WUS.

Abstract: A user equipment (UE) reports radio access capabilities to a network. The UE receives a request from a network for radio access capabilities of the UE, determining one or more radio access capabilities related to physical downlink control channel (PDCCH) blind decoding by the UE, generates a message that includes the one or more radio access capabilities of the UE and transmits the message to the network.

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 method, UE and integrated circuit for reporting RSTD values to a network. A user equipment (UE) is configured to establish a connection to a network, the network comprising a first cell and a second cell. The UE receives a positioning reference signal from each of the first and second cells, determines a frequency band for each of the positioning reference signals, determines reference signal time difference (RSTD) values from measured time offsets between the positioning reference signals from the first and second cells, determines RSTD reporting values based on at least the RSTD values and the determined frequency bands and transmits an indication of the RSTD reporting values to the network.

Abstract: Techniques for identity-based message integrity protection and verification between a user equipment (UE) and a wireless network entity, include use of signatures derived from identity-based keys. To protect against attacks from rogue network entities before activation of a security context with a network entity, the UE verifies integrity of messages by checking a signature using an identity-based public key PKID derived by the UE based on (i) an identity value (ID) of the network entity and (ii) a separate public key PKPKG of a private key generator (PKG) server. The network entity generates signatures for messages using an identity-based private key SKID obtained from the PKG server, which generates the identity-based private key SKID using (i) the ID value of the network entity and (ii) a private key SKPKG that is known only by the PKG server and corresponds to the public key PKPKG.

Abstract: A device level lock policy, which applies to all smart secure platform (SSP) applications of a mobile device, is used to determine whether a particular SSP application can be activated. A tamper resistant hardware secure element (SE) includes a primary platform with a low level operating system (OS) and one or more SSP applications within one or more secondary platform bundles that include secondary platforms with high level OSs specific to the secondary platform bundles. The low level OS enforces the device level lock policy for all secondary platform bundles by verifying whether a lock policy for the SSP application is consistent with the device level lock policy. When verification succeeds, activation is allowed, and when verification fails, activation is disallowed. Subscription identifiers are not provided in unencrypted form to processing circuitry of the mobile device external to the tamper resistant hardware SE to provide subscriber identity privacy protection.
