An indication (e.g., a one bit flag) in the MIB is provided, which indication is set to a particular value if the UE needs to read SIB1-BR, otherwise the indication is set to a different value indicating that the UE can skip reading SIB1-BR assuming other conditions are met (e.g., assuming that the UE has previously read SIB1-BR within a MIB indication time period).

Abstract: Random Access (RA) formats are defined for NB-IoT operation in TDD mode. The formats are defined to allow use of the legacy LTE subframe configurations for TDD. The formats specify a predetermined, even number P of symbol groups composing a RA preamble, wherein each symbol group comprises a Cyclic Prefix (CP) and a number X of symbols. The P symbol groups are divided into symbol group sets fitting into 1, or 2, or 3 contiguous uplink subframes, each comprising at least two symbol groups transmitted back-to-back (i.e., contiguously in time), and at least two symbol group sets are transmitted non-contiguously in time across a number of uplink subframes over which the RA preamble is transmitted. The number of symbol groups in a set can be two or three, and the number of symbol groups is four or six, respectively. Symbol groups within a set are transmitted on adjacent uplink subframes. Five format options are defined, which map to various of the LTE TDD configurations.

Abstract: According to certain embodiments, a method includes determining that at least one condition is met while a wireless device is in a power saving mode (PSM) and no non-access stratum (NAS) connection is established.

Abstract: Systems and methods for determining timing advance (TA) validity are disclosed. In some embodiments, systems and methods are disclosed herein in which a wireless device implicitly considers a TA to be valid in a full cell when no TA validation mechanisms are explicitly configured. In other embodiments, systems and methods are disclosed herein in which a timer serves a dual purpose. If the timer is set to infinity, a wireless device will always consider a TA to be valid within a given cell, and at the same time will disable other TA validation mechanisms. Otherwise, the wireless device will interpret the timer as indicating for how long the TA value that the wireless device possesses is considered to be valid. Benefits of the solutions described herein include reducing signaling bits in the configuration and avoiding the possibility of conflicting configurations.
