  • Publication number: 20210099944
    Abstract: A technique for transmitting system information for a time-division duplex, TDD, communication in a radio access network, RAN, is described. As to a method aspect of the technique, a master information block, MIB, is transmitted on an anchor carrier (602 1) of the TDD communication in the RAN. The MIB is indicative of a spectral resource (602-1; 602-2) allocated to a system information block, SIB, of the TDD communication in the RAN. The SIB is transmitted on the spectral resource (602-1; 602-2) indicated in the MIB.

  • Publication number: 20200245365
    Abstract: Random Access (RA) formats are defined for NB-IoT operation in TDD mode. The formats are defined to allow use of in 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.

  • Publication number: 20200120744
    Abstract: A network node (200), a wireless device (202) and methods therein, for handling discontinuous transmission, DTX, in a communication using multiple uplink carriers. The communication involves a primary uplink carrier using a first Transmission Time Interval, TTI and a secondary uplink carrier using a second TTI which is different than the first TTI. Values of DTX parameters defined for only one of the first and second TTIs are selected (2:4) for the communication, and the wireless device (202) is instructed (2:7) to use the selected values of DTX parameters for transmission on both the primary uplink carrier and the secondary uplink carrier. Thereby, misalignment of DTX cycles employed on the two uplink carriers can be avoided or reduced.

  • Publication number: 20190273591
    Abstract: A base station and wireless device are configured to support TDD operation. In exemplary embodiments, the base station or UE can make use of the available symbols in the DwPTS or UpPTS of a special subframe respectively for NB-IoT transmissions. In one example, the base station can use OFDM symbols in the DwPTS to repeat in a predetermined manner some of the symbols transmitted in an immediately preceding downlink subframe, or in a succeeding downlink subframe. In other embodiments, the UE can use symbols in the UpPTS to repeat in a predetermined manner some of the symbols transmitted in the immediately succeeding uplink subframe, or in a preceding uplink subframe. The symbols repeated in the special subframe can be coherently combined at the receiver with corresponding symbols transmitted in a downlink or uplink subframe to improve decoding performance, reduce errors, improve channel estimation, and increase system capacity.

  • Patent number: 10149316
    Abstract: The present invention relates to granting time intervals for transmitting a control signal burst and, more particularly, to methods and devices for granting Dedicated Physical Control Channel (DPCCH) bursts for Wideband Code Division Multiple Access (WCDMA). A base station determines whether a predetermined condition for transmitting a grant signal is satisfied and, if so, determines a schedule for receiving a control signal burst from a mobile device and transmits, in accordance with the determined schedule, the grant signal to at least said mobile device. Correspondingly, a mobile device transmits a report to a base station causing it to determine, in accordance with the report, a schedule for transmitting a control signal burst. Then the mobile device receives grant signals in accordance with the determined schedule and transmits a control signal burst in accordance with the grant signal.
