Receiving a random access response message which includes a response to the random access preamble message is also included in the method. The response includes UL resource allocation information for scheduling an UL transmission. The UL resource allocation information includes information identifying one or more individual time subframes allocated for the UL transmission. The method also includes sending the UL transmission in the identified one or more individual time subframes.

  • Publication number: 20130081026
    Abstract: In communication systems, for example Long Term Evolution (LTE) of the 3rd Generation Partnership Project (3GPP), using two cycles (long and short) to configure uplink (UL) scheduling request (SR) resources, and various ways of configuring a short scheduling request cycle may be able to add flexibility for a network (NW) to configure scheduling request cycles, allowing balance between latency and resource reservation. A method, according to certain embodiments, can include detecting that there is data activity associated with a user equipment and activating a short scheduling request cycle upon the detecting the data.

  • Patent number: 8385966
    Abstract: A first power control adjustment state g(i) and a second power control adjustment state f(i) are initialized for i=0 to each reflect an open loop power control error. An initial transmit power for a shared uplink channel is computed using full pathloss compensation. The computed initial transmit power depends on a preamble power of a first message sent on an access channel, and the initial transmit power is initialized with the second power control adjustment state f(0). A third message is sent from a transmitter on an uplink shared channel at the initial transmit power. In various implementations, the power for i=0 on the uplink control channel is also initialized similar to the initial transmit power for the third message and using full pathloss compensation, and after the third message (and retransmissions of it), subsequent messages sent on the uplink shared channel are sent at a power that is computed using fractional pathloss compensation.

  • Publication number: 20100093364
    Abstract: An approach for providing interference measurements for device-to-device communication is disclosed. A logic generates a control signal to instruct a plurality of stations to perform measurement relating to interference or path loss by the stations. The logic then receives measurement information from the stations and determines, based on the measurement information, whether resources are to be scheduled to provide direct communication between two of the stations.
