  • Publication number: 20200245396
    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.

  • Publication number: 20200245378
    Abstract: A method, a computer-readable medium, and an apparatus are provided for wireless communication at a User Equipment (UE). The UE receives a second random access message from the base station after transmitting a first random access message. The second random access message comprises a random access response (RAR) that indicates a narrowband to be used for receiving a fourth random access message. The apparatus determines whether to perform a measurement of the narrowband for the fourth random access message based on an amount of time between receiving the second random access message and transmitting a third random access message. The base station may determine whether the report comprises a measurement of the first narrowband or the second narrowband based on an amount of time between the second random access message and the third random access message or based on an indication in the third random access message.

  • Patent number: 10708956
    Abstract: Various features presented herein facilitate early data transmission (EDT) in eMTC and NB-IoT. In certain aspects, a UE (e.g., an eMTC and/or NB-IoT type device), may receive an indication in a SIB from a base station that may enable EDT by the UE. The UE may transmit a random access request based on the SIB. The UE may further receive an MCS index in an RAR, and transmit a connection request (e.g., Msg3) to the base station based on the MCS index and the indication in the SIB. Some aspects described herein relate to an improved rate matching technique. In certain aspects, a UE may be configured to transmit a connection request message to a base station based on at least one of an increased number of RVs than a number of RVs for other transmissions from the UE or rate matching performed across more than one subframe.

  • Publication number: 20200154356
    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.

  • Publication number: 20200137624
    Abstract: Methods, systems, and devices for wireless communications are described that support channel quality reporting using random access messages. A user equipment (UE) may receive a random access message from a base station and respond with an indication of channel quality information for a communication link between the base station and the UE. The indication may be generated by a single protocol layer of a control plane protocol stack (e.g., a radio resource control (RRC) or media access control (MAC) layer). The channel quality information may be included in the RRC message or in a header of the MAC layer from the UE. The UE may transmit, to the base station, an indication of identified channel quality information. Upon receiving the response message from the UE, the base station may determine communication parameter(s) (e.g., coding rate, modulation order, number of repetitions of a channel) for future communications with the UE.

  • Publication number: 20200107356
    Abstract: A method for early termination of an ongoing uplink transmission based on implicit HARQ-ACK is disclosed. A wireless device may receive a first grant for a first uplink transmission and may begin repetitions of the first uplink transmission. The wireless device may receive a second grant for a second uplink transmission during the ongoing first uplink transmission. The wireless device may determine if the second grant is an implicit HARQ-ACK and may perform an early detection of the HARQ-ACK. The wireless device may terminate early the first uplink transmission based on the detection of the HARQ-ACK. Allowing the wireless device to terminate the first uplink transmission through an implicit HARQ-ACK frees up channel resources and saves power. The wireless device may also start the second uplink transmission earlier than a schedule time based on the early detection of the HARQ-ACK, eliminating the waste of unused uplink resources and saving power.

  • Publication number: 20190357107
    Abstract: Methods, systems, and devices for wireless communications are described. A user equipment (UE) may measure a physical channel such as a narrowband physical broadcast channel (NPBCH) to supplement (e.g., or as an alternative to) reference signal measurements when determining a received signal measurement, such as a received signal strength or received signal quality of a cell. A base station may transmit an indication to a UE that identifies the frequency at which a portion of NPBCH transmissions (e.g., reserved fields of a master information block (MIB)) is expected to change from one NPBCH transmission to another. The UE may adjust its utilization of NPBCH for determining the received signal measurement based on the indication. Further, the UE may communicate with the cell based on the determination of the received signal measurement, which are based on the indication.
