  • Publication number: 20180176954
    Abstract: Access to unlicensed bands is typically preceded by a LBT or CCA mechanism, through which the transmitter determines the presence of ongoing transmissions in the same channel. Specifically, an AP or STA (prior to transmitting) senses the channel, and transmits only if the channel is adjudged to be idle. As mandated by the current IEEE 802.11 standard, the energy detected in the channel is compared with a predefined CCA threshold (signal detect threshold is ?82 dBm and energy threshold is ?62 dBm for 20 MHz OFDM transmission). This creates an RF-energy based guard zone around each transmitter and hence prevents any other transmitter from reusing the medium. To fully leverage simultaneous transmit and receive capability at an AP, it is desirable for the AP to simultaneously send downlink data to a STA while receiving UL data from another STA. However, with traditional CCA methods, the downlink transmission would be blocked.

  • Publication number: 20180176869
    Abstract: In a radio access network, user equipment (UE) is to encode signaling for sector-sweep transmission to a base station via a plurality of directional beams in a millimeter-wave radio band over a random-access shared channel during at least one contention period, and determine a transmission power setting for the directional transmission. The transmission power setting is based on a targeted received signal characteristic to be achieved at the base station using a selected beam direction, and the transmission power setting is determined based on transmission parameters of the UE and reception parameters of the base station, and on channel characteristics. The UE is to initiate transmission of the signaling using the transmission power setting for the plurality of directional beams, wherein the signaling is transmitted to be received according to a targeted received signal characteristic to be achieved at the base station.

  • Patent number: 9942793
    Abstract: A user equipment (UE) is configured to receive a maximum probability of accessing a wireless local area network (WLAN) for communication. The maximum probability is received via a 3rd Generation Partnership Project (3GPP) communication link with an Evolved Universal Terrestrial Radio Access Network (E-UTRAN) Node B (eNB). The UE is further configured to determine that there is a queued transmission for the UE and, in response to determining that there is a queued transmission, to determine whether the UE is authorized to access to the WLAN using a probability less than or equal to the maximum probability. The UE is further configured to delay contention for access to the WLAN for at least a pre-backoff duration in response to determining that the UE is not authorized.

  • Publication number: 20170290058
    Abstract: Disclosed herein are systems and methods that are directed to alleviating the hidden node problem occurring in wireless systems by using the simultaneous transmission and reception (STR) capability without increasing the medium access layer (MAC) overhead. Accordingly, a receiving device receiving a data packet from a transmitting device can simultaneously transmit a data packet, called a STR Clear to Send (CTS). This STR-CTS can create a guard zone around the receiving device to avoid collisions from unwanted transmissions from secondary devices, e.g., neighboring STAs and/or APs. In various embodiments, the STR-CTS packet transmitted by the receiving device can be decodable by legacy devices, e.g. legacy STAs and APs, as well as next generation devices, for example, those employing unlicensed technologies such as LAA.

  • Patent number: 9699800
    Abstract: Systems and methods for bearer splitting among multiple radio links are disclosed herein. User equipment (UE) may be communicatively coupled to an Evolved Universal Terrestrial Radio Access Network (E-UTRAN) Node B (eNB) by multiple radio links (e.g., an LTE link and a WLAN link). A transmitter may dynamically determine a splitting policy for how to split traffic among each link (e.g., what proportion to send over each link). In some embodiments, the transmitter may determine the splitting policy explicitly based on lower layer metrics. Alternatively, or in addition, each radio access interface may request data when a transmission opportunity becomes available, and the splitting policy may be determined implicitly from the data requests. For a UE, the splitting policy may be determined with network assistance, which may include a resource allocation for an LTE link, a probability of successful transmission over a WLAN link, and/or the like.
