  • Patent number: 9635650
    Abstract: A technique for reducing a time delay between an application output at a subscriber station and uplink resource allocation for the subscriber station includes scheduling, between periodic uplink resource allocations, one or more probe uplink resource allocations for the subscriber station. Next, respective information in at least one of the one or more probe uplink resource allocations is received at an access point.

  • Patent number: 9282575
    Abstract: A system and method for reducing access channel delay in a wireless communication system includes a step 601 of sending an initial access request response that includes identifiers of any initial access requests, including an indicator that indicates whether any more responses with identifiers are going to be sent within a predefined time period. A next step 602 includes receiving the response. A next step 604 includes recognizing that a particular identifier from the initial access request is not in the response. A next step 606 includes determining from the indicator that there will be no more responses with identifiers sent within the predefined time period. A next step 608 includes transmitting another initial access request before the end of the predefined time period.

  • Patent number: 9107118
    Abstract: A method, a system and an evolved nodeB (eNodeB) that enable user equipment (UE) to switch between carrier groups in a multi-carrier network. A carrier selection and switching (CSS) utility identifies a first and a second set of pre-configured groups of carrier frequencies that are subsequently assigned to a particular UE. The CSS utility notifies the UE of the assigned, pre-configured groups of carrier frequencies and provides the UE with system parameters associated with the first and second pre-configured groups of carrier frequencies. The CSS utility signals the UE to initiate communication via the first preconfigured group of carriers. Based on the occurrence of pre-established conditions, the CSS utility utilizes a switch signal to indicate via physical downlink control channel (PDCCH) to the UE (a) when to begin utilizing the second group of preconfigured carrier frequencies and (b) when to make subsequent switches between carrier groups.

  • Patent number: 8867454
    Abstract: A method of allocating resources and signatures of a random access resource (RACH) (200) that includes dedicated (202) and non-dedicated (204) resources or sub-resources is disclosed. The network device determines if the dedicated resource is available for allocation. If the dedicated resource is available, the network device allocates the dedicated resource. If the dedicated resource is blocked, the network device allocates one of the non-dedicated resources. A message can be sent that indicates that allocated non-dedicated resource is being allocated as a dedicated resource.

  • Patent number: 8767596
    Abstract: A user equipment and method for contention-based uplink access to a base station. Contention-based configuration data identifies multiple contention-based access zones along with minimum power headroom values for each contention-based access zone. The user equipment devices can randomly select a demodulation reference signal parameter value when transmitting on a selected contention-based access zone.

  • Patent number: 8711789
    Abstract: A base station employs control signaling for contention-based uplink access from user equipment devices to the base station. Contention-based access configuration is performed via physical downlink control channel signaling. Configuration data sent to the user equipment devices identifies multiple contention-based access zones, along with minimum power headroom values for each contention-based access zone. A probability factor may be used to lower collision possibility by influencing whether the user equipment devices perform contention-based uplink access.

  • Patent number: 8625442
    Abstract: A wireless communication system as described here employs control signaling for contention-based uplink access from user equipment devices to a base station. Contention-based access configuration is performed via physical downlink control channel signaling. Configuration data sent to the user equipment devices identifies multiple contention-based access zones, along with minimum power headroom values for each contention-based access zone. A probability factor may also be used to lower collision possibility by influencing whether the user equipment devices perform contention-based uplink access. An uplink grant message can be used to acknowledge contention-based transmission; contention resolution is achieved implicitly via the uplink grant.

  • Patent number: 8498645
    Abstract: The present disclosure provides for a method for allocating by a plurality of source base stations of a cellular wireless communication support infrastructure a temporary resource request identifier to a wireless communication device for accessing a target base station. The method includes identifying a list of temporary resource request identifiers associated with the target base station for use by one or more wireless communication devices, wherein the list includes a subset of one or more part time temporary resource request identifiers whose respective assignment to a corresponding grouping of one or more source base stations at a particular time is rotated between more than one of the plurality of corresponding groupings of one or more source base stations.

  • Patent number: 8311593
    Abstract: A method and an apparatus that includes establishing a link (106) between a first node (102) and a second node (104) in a wireless communication network (100). The method continues by setting a discontinuous receive (DRX) transmission mode cycle for the link wherein the DRX cycle includes an on duration (202) followed by an off cycle (204). The duration of the on duration on a downlink is adjusted (610) based on a function of the availability of a channel quality indicator (CQI) channel used on the link.
