摘要:
An apparatus includes a User Equipment (UE) having a receiver and a decoder. The receiver is configured to receive, from an eNodeB (eNB), a signal indicating a configuration of a period to receive one or more Physical Downlink Control CHannels (PDCCHs) in respective one or more Transmission Time Intervals (TTIs). Each of the one or more PDCCHs conveys a same Downlink Control Information (DCI) format.
摘要:
A method of supporting group communication over LTE MBMS is provided. A UE first establishes a unicast Evolved Packet Service (EPS) bearer in an LTE network for group communication. The UE belongs to a communication group having a communication group ID. The UE receives access information from the network for monitoring downlink (DL)multicast traffic of the DL group communication based on a multicast decision. The UE is then ready for monitoring a multicast Multimedia Broadcast Multicast Service(MBMS) bearer for receiving the DL multicast traffic. The multicast MBMS bearer is associated with a Temporary Mobile Group Identifier (TMGI), and wherein the TMGI is associated with the communication group ID. The UE de-multiplexes DL traffic received either from the multicast MBMS bearer or from the unicast EPS bearer into a single group communication application.
摘要:
Resource blocks in a Long Term Evolution (LTE) network may be allocated by determining a maximum number of user equipments (UEs) in the LTE network that are permitted to transmit in a time period using a given resource block. This maximum number of UEs may be determined according to an upper limit on the overall transmission power in the LTE network for the given resource block. The given resource block may be allocated in the time period to up to the maximum number of UEs based on each UE's geographic location within the network. Related systems, methods, and devices are disclosed.

A technology for a user equipment (UE) in a multiple radio access technology (multi-RAT) heterogeneous network (HetNet) that is operable to receive node-selection pricing information from a plurality of nodes in the multi-RAT HetNet. Effective normalized rate can be determined for the plurality of nodes in the multi-RAT HetNet using the node-selection pricing information. A node can be selected to communicate with in the multi-RAT HetNet to maximize a selected preference based on the effective normalized rate.
摘要:
A method of receiving data at a communications terminal from an OFDM wireless communications network which provides a wireless access interface for communicating the data using a plurality of OFDM sub-carriers comprises receiving from a first control channel having a bandwidth corresponding to a first frequency band providing a first plurality of OFDM sub-carriers are source allocation message allocating communications resources of a second group of OFDM sub-carriers. The second group of the plurality of OFDM sub-carriers is smaller than the first group of the plurality of OFDM sub-carriers and the second frequency band is selected from within the first frequency band to form a virtual carrier. The method includes receiving from a second control channel within the second frequency band within the second group of OFDM sub-carriers control information which is specific to the communications terminal operating to receive the data via the second group of OFDM sub-carriers. The communications terminal thereby receives resource allocation messages from the first control channel to allocate resources within the second frequency band forming the virtual carrier and to receive control information,which is specific to the communications terminal,which is receiving data from the second frequency band of the virtual carrier via a second control channel. Accordingly, there is provided a logical separation of full bandwidth LTE type terminals and communications terminals of a reduced bandwidth of the second type in respect of the transmission of control information, but uses the same resource allocation messages for both the full-bandwidth LTE terminals and the reduced bandwidth terminals of the second type thereby improving compatibility with conventional LTE networks.

摘要:
An extended wireless access point may have many distributed radio units connected to associated processing units via a radio transmission network comprising commodity switches controlled by one or more network controllers. The one or more network controllers may use a load balancing algorithm to select a processing unit to process a signal received by a distributed radio unit. The radio units may receive a wireless signal, and generate compressed samples of the wireless signal for transport via the radio transmission network and processing by a selected processing unit. Similarly, a processing unit may generate and transmit via the radio transmission network compressed samples for decompression and transmission by a radio unit.
