Abstract: In a first configuration, the apparatus may be a base station. The base station adjusts a periodicity for performing a beam sweep, sends information indicating the adjusted periodicity for performing a beam sweep, and performs the beam sweep at the adjusted periodicity. In a second configuration, the apparatus may be a UE. The UE receives information indicating a periodicity for performing a beam sweep from a base station, adjusts the periodicity for performing the beam sweep, and performs the beam sweep at the adjusted periodicity. For both configurations, the beam sweep is a plurality of transmissions of a beam in a plurality of different transmit spatial directions by one of the base station or the UE and a plurality of scans of the beam transmissions in a plurality of different scan spatial directions by an other of the one of the base station or the UE.

Abstract: A method, an apparatus, and a computer program product are provided. The apparatus determines a channel gain to a second wireless device with which the first wireless device is communicating. In addition, the apparatus determines interferer backoff information that ensures an interference level at the first wireless device such that a signal received from the second wireless device can be decoded reliably. The interferer backoff information is determined based on the channel gain. Furthermore, the apparatus transmits information based on the interferer backoff information in one of an RTS message or a CTS message to the second wireless device.

Abstract: Chase combining gains for receiving a scrambled broadcast channel can be achieved even when a portion of each received channel coded transmission contains a portion that varies. A set of possible difference values for this varying portion, such as for a system frame number, provides hypotheses, each having a corresponding probability. One or more of the hypotheses are selected by rank order for adjusting a corresponding received coded transmission so that two or more channel coded transmissions can be combined and blind decoded until one of the hypotheses are confirmed.

Abstract: Systems and methods are described to supply positioning reference signal (PRS) in a telecommunication system. A base station supplies a PRS sequence according at least to a time-frequency pattern of modulation symbols, wherein the time-frequency pattern assigns a modulation symbol to each frequency tone in a block of time-frequency resources allocated to transmit PRS. The base station associates a modulation symbol in the time-frequency pattern with a reference symbol in the PRS sequence through a mapping that represents the time-frequency pattern. The PRS sequence is conveyed to user equipment through delivery of a set of modulation symbols established through the mapping. Different time-frequency patterns can be exploited based on time-structure of a radio sub-frame. The user equipment receives the PRS sequence according to at least the time-frequency pattern of modulation symbols and utilizes at least the PRS sequence as part of a process to produce a location estimate.

Abstract: A method of scheduling among a plurality of nodes may include performing a first sequence of steps followed by a second sequence of steps, each sequence including a Tx step followed by a Rx step. During the Tx step, a node may send a REQ signal containing a request to transmit. During the Rx step, another node may receive the request signal, and respond by sending a confirmation signal indicating an acceptation or a declination of the REQ signal. The REQ signal includes a unicast portion and a broadcast portion. In an uplink mode of the slot, the responding nodes may use the unicast portion of the REQ signal to send supplemental information, in addition to the indication of the acceptation or the declination of the REQ signal.

Abstract: Signaling-only access may be established with an access node (104) under certain circumstances such as, for example, upon determining that a node (102) is not authorized for data access at the access node (102). A node (104) that is not authorized for data access at an access node (104) may still be paged by the access node (104) through the use of signaling-only access. In this way, transmissions by the access node (104) may not interfere with the reception of pages at the node (302). A first node may be selected for providing paging (102) while a second node (106) is selected for access (304) under certain circumstances such as, for example, upon determining that the second node provides more desirable service than the first node.

Abstract translation: 在特定情况下，例如在确定节点（102）不被授权用于在接入节点（102）处的数据访问时，可以在接入节点（104）上建立仅信令访问。 在接入节点（104）处未被授权用于数据接入的节点（104）仍然可以由接入节点（104）通过使用仅信令接入进行寻呼。 以这种方式，接入节点（104）的传输可能不干扰节点（302）处的页面的接收。 可以选择第一节点来提供寻呼（102），而在某些情况下例如在确定第二节点提供比第一节点更理想的服务之后，第二节点（106）被选择用于接入（304）。
