A method for channel signaling is described. The method includes determining (e.g., by a UE) whether at least one DL subframe is a valid reference resource. If the at least one DL subframe is not a valid reference resource, reporting measurements of a DL channel measured during the at least one DL subframe is inhibited. The method may include determining (e.g., by an eNB) whether reporting of the at least one DL subframe of a DL channel is required. If reporting is not required, a message configured to cause the at least one UE to inhibit reporting measurements of the DL channel (e.g., CQI measurements) measured during the at least one DL subframe is sent to the UE. Determining whether the at least one downlink subframe is a valid reference resource is based at least in part on the message. Apparatus and computer readable media are also described.

Reduction of unnecessary downlink control channel reception and decoding

In accordance with an example embodiment of the present invention, an apparatus, comprising at least one processor; and at least one memory including computer program code; the at least one memory and the computer program code configured to, with the at least one processor, cause the apparatus to perform at least the following: deciding to switch to a half-duplex mode of operations upon detecting a triggering condition including that multiple radio stacks are activated at the apparatus simultaneously; signaling an associated base station the decision of switching to the half-duplex mode half-duplex mode; and entering the half-duplex mode of operation, is disclosed.

Method and apparatus for avoiding interference between multiple radios in a user equipment

A semi-persistent uplink resource allocation that includes an indication to send a channel quality indicator may be provided to a user equipment (UE) in a wireless network. The UE may send a channel quality indicator with data to a network.

Channel quality signaling for semi-persistent radio resource allocations

In one exemplary embodiment of the invention, a method includes: measuring at least one characteristic of a secondary component carrier to obtain a measurement result, where measuring is performed by an apparatus while the apparatus is in communication with a network via a primary component carrier with a network access node; and in response to the measurement result of the at least one characteristic being below a threshold, and further in response to receiving from the network access node an activation command for the secondary component carrier, considering the secondary component carrier as being undetectable.

User equipment carrier activation

Method, operation of a method, and a result of execution of computer program instructions embodied on a non-transitory computer readable memory in a mobility management entity which determines whether a source and destination address of certain Internet protocol data flow are within a specific network in an evolved packet system for evaluating and controlling potential opportunities for device to device communication among two or more proximately located user equipment. In response to determining that the target serving gateway is the source gateway, identification information of the source user equipment is sent to a target serving gateway.

Direct communication among devices

In an exemplary embodiment there is sent to a user equipment UE downlink control information DCI comprising an indication of an access codeword and an indication that at least one component carrier CC is activated for the UE, and there is received from the UE the access codeword which is an acknowledgement that the UE has activated the at least one CC. The access codeword is received on an uplink channel which a) lies in the at least one activated CC if there is an activated uplink channel in the activated CC, or b) is previously activated if there is no activated uplink channel in the activated CC. In another embodiment DCI comprising the above two indications is received from a network, the received indications are used to select and access the at least one CC; and activating the CC is acknowledged by sending the access codeword.

Activating component carriers in a carrier aggregation

The specification and drawings present a new method, apparatus and software related product (e.g., a computer readable memory) for implementing a D2D discovery resource allocation by a network for D2D discovery by UEs belonging to multiple cells in a D2D discovery area, e.g., in LTE wireless systems. A network such as LTE may determine an allocation of one or more resources (UL and/or DL) for a device-to-device discovery among a plurality of UEs located in multiple cells of the network in a D2D discovery area. The allocation of the one or more resources is then may be provided by the network to the plurality of UEs for performing, using these one or more resources, the D2D discovery between any two UEs of the plurality of UEs located in the multiple cells in the D2D discovery area.

Device-to-device discovery resource allocation

Method, operation of a method, and a result of execution of computer program instructions embodied on a non-transitory computer readable memory in a mobility management entity which identify, evaluate and control potential opportunities for device to device communication among two or more proximately located user equipment. The method or execution of computer instructions include, determining a context of a source user equipment and a context of a target user equipment, determining if the source and target user equipment are device to device communication compatible and determining if the source and target user equipment are authenticated for employing device to device communications. An alternative embodiment includes functionality in a base station.

An apparatusemployable in a communication system configured to determine a value for a new data indicator for semi-persistently allocated or scheduled resources. In one embodiment, the apparatusincludes a processorconfigured to receive a cell radio network temporary identifier indicating a semi-persistent scheduling. The processoris also configured to treat a reception of data with a new data indicator flag in accordance with the semi-persistent scheduling as one of a persistent initial transmission if a value of the new data indicator flag is equal to a first predefined value, and a retransmission of semi-persistent scheduling data if the value of the new data indicator flag is equal to a second predefined value.

Data indicator for persistently allocated packets in a communications system

There is stored in a memory an association between each none of N content types with a respective ngroup of N groups of identifiers (N is an integer greater than one, n indexes from 1 to N, and at least one of the groups has more than one identifier). A beacon sender selects one of the content types for a beacon to be transmitted and selects a beacon identifier from the group associated with the selected content type. The beacon to be transmitted is compiled to include content of the selected content type and the selected beacon identifier. The beacon receiver selects at least one of the content types; and for a plurality of beacons received, filters out from further processing each beacon having a beacon identifier that is not within the group of identifiers associated with any of the at least one selected content types. The network creates the association and broadcasts it in a network cell.
