Abstract:
Techniques for managing re-contention on a shared communication medium are disclosed. In order to facilitate re-contending for access to the communication medium, an access point may adjust one or more uplink transmission parameters associated with a triggering condition for invoking a contention timer. In addition or as an alternative, the access point may mute transmission on the communication medium during one or more symbol periods designated for transmission. In addition or as an alternative, the access point may configure a timing advance to create a re-contention gap.
Abstract:
gerenciamento de informações de relação de vizinhos. o gerenciamento de informação de relação de vizinhos envolve, por exemplo: adquirir, relatar e trocar informação de relação de vizinhos. em alguns casos, a informação de relação de vizinhos é adquirida e/ou relatada de modo que não causa impacto significativo sobre outras funcionalidades do terminal de acesso. por exemplo, um terminal de acesso pode ser configurado para adquirir e/ou relatar informação de relação de vizinhos apenas durante um ou mais estados de rádio definidos. em alguns casos, a aquisição de informação de relação de vizinhos é baseada em terminal de acesso não relata imediatamente a informação de relação de vizinhos medida e em vez disso armazena a informação para relatar posteriormente, em alguns casos, uma indicação transmitida é utilizada para facilitar a recuperação de informação de relação de vizinhos de um terminal de acesso. em alguns casos, a informação de relação de vizinhos adquirida de um terminal de acesso é trocada através de uma interface direta entre pontos de acesso.
Abstract:
A UE determines to send a transmission to a first base station on a first unlicensed frequency channel. The UE determines, for one or more attempts of a listen before talk (LBT) protocol, whether each attempt is a failed attempt or a successful attempt. The UE determines that the first unlicensed frequency channel is one of unavailable based on the LBT protocol failing due to a number of failed attempts exceeding for a first threshold number of failed attempts or a duration of failed attempts exceeding a first threshold duration, or available based on the LBT protocol being successful. The UE sends a report to the first base station indicating whether the first unlicensed frequency channel is unavailable or available through a unicast radio resource control (RRC) message or a medium access control (MAC) control element (CE).

Abstract:
Methods, systems, and devices for wireless communication are described. A user equipment (UE) may monitor for discovery reference signal (DRS) transmissions, physical downlink shared channel (PDSCH) transmissions, or combinations thereof within a DRS transmission window. The UE may attempt to decode DRS or PDSCH transmissions for a subframe based on detection of DRS transmissions, prioritization of DRS transmissions relative to PDSCH transmissions, locations of subframes within a radio frame, overlapping of the DRS transmission window with a paging opportunity, or any combination thereof. In some cases, one or more radio link monitoring (RLM) parameters may be adjusted based on decoding of PDSCH or DRS transmissions.

Abstract:
The present disclosure presents methods and apparatuses for improved data rates in a wireless communications environment wherein a user equipment (UE) may receive and transmit signals from a plurality of network entities (NodeBs) which are controlled by separate radio network controllers (RNCs). For example the disclosure presents a method of wireless communication in a multiflow environment which includes establishing a first flow between a serving radio network controller (S RNC) and a first network entity wherein the S RNC controls the first network entity. The method also includes establishing a second flow between the S RNC and a second network entity which is controlled by a drift radio network controller (D RNC). Furthermore the method includes transmitting data to the UE via both the first flow and the second flow.
Abstract:
The application relates to the detection of local cell identifier collision by a base station. For identification purposes, each base station in the network (200) may be assigned or otherwise select a local cell identifier (e.g., a physical cell identifier (PCI), a pilot pseudorandom number (PilotPN), or some other type of identifier) intended to be unique in a given geographical region. Because of its limited geographical reach, the local cell identifier can be use a relatively small number of bits and still be in principle (locally) unique in a given area. However, for the same reasons, the quantity of local cell identifiers defined in a given system is limited (e.g., on the order of one to several hundred in some systems). Meanwhile, femto base stations, such as the femto base stations (210) and (212) in FIG. 2, may be deployed in potentially large numbers throughout homes, apartment buildings, office buildings, etc., and by individual consumers without the central planning conventionally used in macro networks to coordinate the distribution of local cell identifiers. Thus, identifier conflict among base stations in femto networks as well as mixed networks, and the problems associated therewith, have the potential to be more widespread and more detrimental than in conventional macro networks where deployment and base station identification is more closely controlled. In one particular type of conflicting use, referred to as identifier "collision," two base stations in close proximity to one another may inadvertently use the same local cell identifier in a manner that causes a user device in that region to concurrently receive signals (e.g., pilot signals) comprising the same local cell identifier from two otherwise distinct base stations. The resulting identifier collision between femto base stations (210) and (212) may lead to several problems. Therefore, the application proposes to detect collision as follows. The femto base station (210) detects that the PCI received in the RRCConnectionReestablishmentRequest message matches its own PCI (i.e., the PCI of the femto base station (210)) but that the c-RNTI does not match any of the c-RNTIs that the femto base station (210) has assigned to any user devices that it is serving (e.g., the user device (222)). Accordingly, the femto base station (210) determines that the RRCConnectionReestablishmentRequest message is in fact intended for another neighboring base station using the same PCI as itself (i.e., the femto base station (212) in this example, although its identity may be unknown to the femto base station (210)).
