    Abstract: In some aspects, a user equipment (UE) may receive downlink control information (DCI) that includes a timing value indicating a timing of an opportunity, subsequent to reception of the DCI, for transmission or reception of a communication corresponding to the DCI. The UE may determine an uplink opportunity or a downlink opportunity for transmission or reception of the communication based at least in part on the timing of the opportunity. A counter for determining the uplink opportunity may be incremented only for transmission time intervals (TTIs) in which the UE is allowed to transmit the communication in an uplink channel. A counter for determining the downlink opportunity may be incremented only for TTIs in which the UE can expect to receive the communication in a downlink channel. The UE may transmit or receive the communication in the uplink opportunity or the downlink opportunity. Other aspects are disclosed.

    Abstract: For downlink control, a method receives by use of a processor 405, at User Equipment 110, a control channel with a first aggregation level in a Transmission Time Interval 230. The method attempts to decode the control channel. In response to the control channel being successfully decoded, the method determines a first downlink control information (DCI) 275 with a first number of bits based on the received control channel; determines whether to decode the first DCI 275 to determine a second DCI 275 with a second number of bits based on the first DCI 275; and determines the second DCI 275 with a second number of bits based on the decoded first DCI 275 if determined to decode the first DCI 275. The method transmits data according to the second DCI 275 if the second DCI 275 is an uplink grant. The method receives data according to the second DCI 275 if the second DCI 275 is a downlink assignment.

    Abstract: A base station is described. The base station includes a processor and memory in electronic communication with the processor. Instructions stored in the memory are executable to receive multiple Contention Based Random Access (CBRA) requests on a Physical Random Access Channel (PRACH) and detect a collision based on the receiving of multiple collision detection (CD) codes associated with a single preamble. The UE includes a processor and memory in electronic communication with the processor. Instructions stored in the memory are executable to send a collision detection (CD) code with a preamble in an access request message of a Contention Based Random Access (CBRA) procedure.

    Abstract: Updating an uplink contention window size in a listen before talk process in a wireless communication system (100) such as LTE may be done by the eNB (101) if transport blocks contained in the starting subframe of a reference scheduled burst transmitted by a User Equipment (103) are successfully decoded at the eNB. Otherwise, the User equipment adjusts the contention window size depending on information supplied by the eNB. This information identifies the first subframe in the burst whose transport block the base station was able to successfully decode. Depending on whether the User Equipment was first transmitting before or on the identified subframe, the User Equipment can either increase or reset the contention window size.

    Abstract: Systems and methods are disclosed that relate to signaling of Time Division Duplexing (TDD) subframe use to short Transmit Time Interval (sTTI) wireless devices. In some embodiments, a method of operation of a network node in a cellular communications network comprises signaling, to a wireless device, an indication of a TDD subframe set to use, where the TDD subframe set specifies subframe selection for legacy transmissions and sTTI, transmissions. In this manner, both sTTI transmissions can be made in selected legacy TDD subframes, which provides latency reduction in frame alignment and Hybrid Automatic Repeat Request (HARQ) Round Trip Time (RTT) for TDD.

    Abstract: An apparatus of a base station includes a memory device and processing circuitry operatively coupled to the memory device. The processing circuitry processes a buffer status report (BSR) from a user equipment (UE) indicating an amount of data in a buffer of the UE. The processing circuitry further determines a ratio of WLAN uplink data to be transmitted on a WLAN channel of the UE to long term evolution (LTE) uplink data to be transmitted on a LTE channel. Furthermore, the processing circuitry encodes a protocol data unit (PDU) indicating the amount, wherein the PDU is to be transmitted to the UE.
