Abstract: A wireless network device may receive a first list indicating a first assignment for uplink and downlink time intervals in a time division duplex (TDD) frame and determine at least first downlink time intervals based on the first list. The device may receive a second list indicating a second assignment for uplink and downlink time intervals in a TDD frame and determine at least first uplink time intervals based on the second list. The device may determine at least second downlink time intervals and second uplink time intervals based on a third list, wherein the third list indicates a third assignment for uplink and downlink time intervals in a TDD frame, and wherein the second downlink time intervals include downlink time intervals of at least the first downlink time intervals and the second uplink time intervals include uplink time intervals of at least the first uplink time intervals.

Abstract: Embodiments contemplate devices and techniques for receiving unicast and multicast transmissions over a downlink (DL) shared channel in parallel, for example an LTE DL shared channel (SCH). For example, one or more hybrid automatic repeat request (HARQ) entities may be configured to perform retransmissions of the multicast and/or unicast messages. Common and/or dedicated (e.g., separate) HARQ entities may be utilized for retransmission. The multicast downlink shared channels may be activated and/or deactivated on demand. The activation and/or deactivation may be performed using radio resource control (RRC) signaling and/or Medium Access Control (MAC) signaling. The multicast and/or unicast downlink shared channel data may include scalable video coding (SVC) data of varying priority. Embodiments also contemplate the use of simultaneous (e.g. parallel) multicast/unicast for scalable video coding transmission over WiFi/802.11 protocol signals.

Abstract: Signals transmitted on the backhaul links of a cloud radio access network may be compressed using joint compression encoding. Joint compression encoding may be performed using a successive estimation-compression architecture. Joint compression encoding may include designing preceding matrices that may be used with signal compression. Joint compression encoding may be applied to signals transmitted on the downlink of the cloud radio access network. One or more baseband signals to be delivered over the backhaul links may be jointly compressed using multivariate compression. Multivariate compression may be implemented using successive compression based on a sequence of minimum mean squared error (MMSE) estimations and per BS compression.

Abstract: An uplink signal may be transmitted by a user equipment (UE) in a time interval using an uplink control channel. The uplink signal may include hybrid automatic repeat request (H-ARQ) control information related to received downlink data. If the UE determines that information indicating a coding and modulation is to be transmitted at a same time interval as the H-ARQ control information, the uplink signal may include the information that indicates the coding and modulation.

Abstract: Methods, apparatuses and systems for performing hierarchical traffic differentiation and/or employing hierarchical traffic differentiation are provided. These methods, apparatuses and systems may be implemented to, for example, handle congestion and/or to manage user quality of experience (QoE). Performing the hierarchical traffic differentiation may include differentiating or otherwise classifying (collectively “differentiating”) traffic mapped to, or within, a bearer formed in accordance with a QoS class into multiple traffic sub-classes. Employing the hierarchical traffic differentiation may include scheduling and/or policing (e.g., filtering) the differentiated traffic for transmission based on a prioritization of, and/or policy for managing, the multiple traffic sub-classes.

Abstract: A user equipment (UE) may receive a first downlink signal, which may include a resource assignment having an indication of a first resource of a plurality of resources. The resource assignment may also have an indication of a number of resources of the plurality of resources. In addition, the plurality of resources may be consecutive resources in a sequence. Further, the first downlink signal may include an indication as to a number of time intervals that the resource assignment applies. Moreover, each time interval may include at least one time slot. Additionally, the UE may receive at least one additional downlink signal over a downlink shared channel in the indicated first resource and in the number of consecutive resources in the sequence in the number of indicated time intervals. In an example, the first downlink signal may be received over a downlink signaling channel.

Abstract: A wireless digital communication system includes a base station in communication with a plurality of user equipment mobile terminals (UEs). The system prioritizes the forwarding of blocks of downlink data to designated ones of the UEs. The system employs adaptive modulation and coding (AM&C) to achieve improved radio resource utilization and provides optimum data rates for user services. Blocks of downlink (DL) data are received by the base station which requests downlink (DL) channel quality measurements only from those mobile terminals (UEs) with pending downlink transmissions. The UEs respond to the request by measuring and reporting DL channel quality to the base station, which then allocates resources such that the UEs will make best use of radio resources. The base station notifies the UEs of the physical channel allocation indicating the modulation/coding rate and allocated slots followed by transmission of blocks of downlink data which are transmitted to the UEs.

Abstract: An uplink signal may be transmitted by a user equipment (UE) in a time interval using an uplink control channel. The uplink signal may include hybrid automatic repeat request (H-ARQ) control information related to received downlink data. If the UE determines that information indicating a coding and modulation is to be transmitted at a same time interval as the H-ARQ control information, the uplink signal may include the information that indicates the coding and modulation.

Abstract: A user equipment (UE) may receive a first downlink signal, including a resource assignment having a first indication of a first resource of a plurality of resources and a number of resources of the plurality of resources in a sequence. The downlink signal may include a second indication as to applying the resource assignment to a single time interval or plurality of time intervals, which the UE may determine. The UE may receive a second downlink signal in the first time interval in the first resource and in the number of consecutive resources in the sequence on a condition that the resource assignment is for a single time interval, and a second downlink signal in each of the plurality of time intervals in the first resource and in the number of consecutive resources in the sequence on a condition that the resource assignment is for the plurality of time intervals.

Abstract: A method and apparatus for adaptive uplink/downlink resource assignment may include determining uplink interference associated with each of several uplink resources. A wireless network device may produce an uplink list with values for the uplink resources. The device may compare a downlink power level to at least one threshold for each of the downlink resources, wherein at least two of the downlink resources are each associated with a different portion of a frame. The device may produce a downlink list, which may be a bit stream providing an indication, for each downlink resource, indicating whether each of the downlink resources have a downlink power level which is less than or equal to the at least one threshold. The device may send the uplink and downlink lists and may receive an uplink list and a downlink list from each of several neighboring wireless network devices.

Abstract: In a wireless network control information may be provided with configuration information for an uplink control channel and a margin associated with the uplink control channel. A signal including an adaptive modulation and coding report may be sent over the uplink control channel in a time interval including a time slot. The transmission power level of the signal may be derived from the margin or a measured pathloss.

Abstract: A method for downlink power control for use in a spread spectrum time division communication system having time slots for communication, implemented in a user equipment, includes receiving data in a command per coded composite transport channel (CCTrCH) transmitted over a plurality of time slots. An interference power for each time slot of the plurality of time slots is measured and a single power command for the entire CCTrCH is transmitted in response to a signal to interference ratio of the received CCTrCH and the measured interference power measurement for each time slot. A subsequent data is received in the CCTrCH communication having a transmission power level for each downlink communication time slot set individually in response to the interference power measurement for that time slot and the single power command for the entire CCTrCH.

Abstract: A method for reporting channel quality from a user equipment (UE) to a base station is described. The UE derives a channel quality for each of a plurality of downlink resources. The UE transmits channel quality reports in a pattern of time intervals by rotating through the plurality of downlink resources in different time intervals of the pattern, wherein a channel quality report is not transmitted by the UE in each time interval of a frame.

Abstract: Splitting data in a wireless communications network. Data may be split to use multiple base stations for transmission to user equipment in order to improve the bandwith if a UE is on a cell edge, or may be split by user equipment for transmission to multiple base stations in order to improve handover. Data splitting may be performed at the Packet Data Convergence Protocol layer, at the Radio Link Control layer, or at the Media Access Control layer on user equipment or on a base station. Data may instead be split in a network node, such as in a serving gateway, in order to reduce X2 interface load or delay carrier aggregation.
