Abstract: Improvements are provided to the paging process for an eMTC UE by allowing a base station and the UE to apply a UE-specific DRX cycle for paging, from one set of DRX cycles, when the UE is operating in non-CE mode and apply another UE-specific DRX cycle, from a more restricted set of UE-specific DRX cycles, when the UE is operating in a CE mode. A UE may report and apply certain UE-specific DRX cycles under non-CE mode, and may change a UE-specific DRX cycle to one from a more restricted set when operating in CE mode. Similarly, base stations may receive the reported UE-specific DRX cycle and apply that UE-specific DRX cycle for paging the UE in non-CE mode, while applying a different UE-specific DRX cycle from the more restrictive set for paging the UE in CE mode.

Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a user equipment may receive information indicating whether measurement is permitted on a non-anchor carrier; and selectively perform a measurement on at least one of the non-anchor carrier or an anchor carrier, based at least in part on the information indicating whether the measurement is permitted on the non-anchor carrier. Numerous other aspects are provided.

Abstract: An aspect of the present disclosure includes methods, systems, and computer-readable media for receiving, at the UE, a random access response including a first signal via a first physical channel and a second signal via a second physical channel from a base station (BS), generating a connection request based on the random access response, estimating a carrier to interference plus noise ratio (CINR) of a random-access channel based on at least one the first signal or the second signal, and sending a message including the CINR and the connection request to the BS in response to the random access response.

Abstract: Methods, systems, and devices for wireless communication are described. Some wireless communications systems may support a determination of user equipment (UE) capabilities, such as a category or a coverage level for broadcast or multicast content. In some cases, a radio interface may be configured to account for an indicated capability of a target UE. For example, a base station may receive an indication of a capability of a particular targeted UE. The capability of the targeted UE may be specified by a service provider to deliver multicast or broadcast content, and subsequently associated with a radio interface between the base station and the target UE. The radio interface may then be configured based on the indicated capability of the target UE, for example, by configuring a transport block size or bandwidth. The base station may then transmit broadcast or multicast content to the UE using the configured radio interface.

Abstract: Techniques described herein use a wakeup signal to indicate to a user equipment (UE) whether an upcoming control channel signal resource includes information relevant to the UE. In this way, the UE can wake up to perform complex control channel signal processing only when the control channel includes signals relevant to the UE, thereby conserving battery power and resources of the UE. Such techniques are particularly suited to MTC UEs, NB-IoT UEs, and/or the like, which may communicate with a network only occasionally, and which may be located in remote locations where changing or recharging a battery is difficult.

Abstract: One feature pertains to a method that includes establishing a radio communication connection with a first radio access node (RAN) that uses control plane signaling connections to carry user plane data. The method also includes determining that the wireless communication device is experiencing radio link failure (RLF) with the first RAN and that the radio communication connection should be reestablished with a second RAN. A reestablishment request message is transmitted to the second RAN that includes parameters that enable a core network node communicatively coupled to the second RAN to authenticate the wireless communication device and allow or reject reestablishment of the radio communication connection. The parameters include at least a message authentication code (MAC) based in part on one or more bits of a non-access stratum (NAS) COUNT value maintained at the wireless communication device.

Abstract: Disclosed are methods and apparatus for selecting a cell having a particular type of service, such as packet switched (PS) service. The methods and apparatus effect determination within a mobile device of signal strength for at least one cell and whether the at least one cell meets signal strength and path loss criteria based on the determined signal strength. A determination is then made whether the at least one cell supports PS for a PS only device, and a selection to receive service from or camp on the cell is then made when the at least one cell has been determined to support PS. By effecting such selection in PS only devices such as Class C devices, the mobile devices will have PS service for which they are designed and avoids cells having only circuit switched service that would provide no service for the PS only device.

Abstract: A method, an apparatus, and a computer program product for wireless communication are provided in which a user equipment performs an inter-radio access technology (RAT) mobility procedure from a first network to a second network while idle mode signaling reduction (ISR) is active, locally deactivates ISR in connection with completion of the inter-RAT mobility procedure, and initiates a location management procedure in the second network. Depending on the respective type of the first and second network, and the connection state of the UE with respect to the first network, the mobility procedure may be performed in response to a mobility command received from the first network, or in response to a mobility condition of the first network as detected by the UE.

Abstract: Various aspects provide for determining whether an Evolved Universal Terrestrial Radio Access (E-UTRA) Absolute Radio Frequency Channel Number (EARFCN) value is greater than a predetermined reserved value for at least one neighbouring cell. If the EARFCN value is greater than the predetermined reserved value, various aspects further provide for including the predetermined reserved value in an E-UTRA Network (E-UTRAN) neighbour cell structure and providing one or more extended EARFCNs used in the E-UTRAN in an extended EARFCN structure included in an existing system information message used in a Global System for Mobile Communications (GSM) random access network (RAN). The predetermined reserved value may be equal to 0xFFFF. The existing system information message may be a SYSTEM INFORMATION TYPE 2quater message according to a GSM Enhanced Data rates for GSM Evolution (EDGE) RAN (GERAN) standard.

Abstract: The present patent application improves DARP by allowing multiple users on one time slot (MUROS). It comprises means and instructions for sharing signals on a single channel, comprising setting up a new connection, allocating a new time slot if there is an unused time slot on a channel frequency, selecting an used time slot for the new connection to share with an existing connection if there is not an unused time slot on the channel frequency, and selecting a different training sequence code for the new connection if the used time slot on the channel frequency has been selected for the new connection to share with an existing connection.
