    Abstract: A network signals an allocation (PDCCH) for a downlink shared channel (PDSCH); and also signals an indication (reference signal RS) whether a resource block (PRB) comprising the allocated downlink shared channel is used for a control channel transmission (E-PDCCH). Examples include the E-PDCCH being time or frequency multiplexed with the PDSCH; and the indication being a different RS sequence (at least one element being phase shifted) than an original RS sequence used if the PRB were not used for the E-PDCCH. The UE tests for the phase shift by blind decoding. If the phase shift is present the UE a) decodes a portion of the PRB for data if the network is using TDM for its E-PDCCH/PDSCH multiplexing, orb) decodes the full PRB only for the E-PDCCH if the network is using FDM for its E-PDCCH/PDSCH multiplexing.

  • Patent number: 8830864
    Abstract: A mobile data network includes a radio access network and a core network. A first service mechanism in the radio access network breaks out data coming from a basestation. When data is broken out by the first service mechanism, the data is delivered at the edge, which means the true activity of the channel is not visible to the core network. The reduction of data in the core network due to serving data at the edge risks causing a switch from a high-speed channel to a low-speed channel by the mechanism in the core network that monitors and assigns channel speeds. In order to maintain the high-speed channel, the on-going data rate for a subscriber session is monitored and channel maintenance traffic is injected towards and from the radio network controller (in both directions). The amount of channel maintenance traffic depends on thresholds that determine a desired data rate.

  • Patent number: 8811975
    Abstract: A wireless communication device (WCD) may transmit a first sequence of access probe messages to a radio access network (RAN) via a first wireless coverage area. The WCD may then transmit a second sequence of access probe messages to the RAN via a second wireless coverage area. Based on the first wireless coverage area being more preferable to the WCD than the second wireless coverage area, the WCD may use a negative inter-sequence power step for the power levels at which the WCD transmits the access probe messages of the first and second sequences. Thus, the WCD may transmit the first access probe message of the second sequence at a lower power than the first access probe message of the first sequence.

  • Patent number: 8811300
    Abstract: In wireless OFDMA systems, midamble is used to facilitate downlink (DL) channel estimation. Midamble signals are transmitted by a base station via a midamble channel allocated in a DL subframe. In a novel symbol-based midamble channel allocation scheme, a midamble channel is allocated in the first or the last OFDM symbol of multiple resource blocks of the subframe, while the remaining consecutive OFDM symbols are used for data transmission. The symbol-based midamble channel provides good coexistence between midamble signals and pilot signals without inducing additional limitation or complexity. Under a novel midamble channel and sequence arrangement, both code sequence and either time-domain or frequency-domain location degrees-of-freedom are considered such that the required number of midamble sequences is substantially smaller than the number of strong interferences.

  • Patent number: 8805427
    Abstract: A computing system in which devices communicate wirelessly as secondary users in a band assigned to primary users. The computers communicate using new signals developed to reduce disruption to primary users of the band. The new signals may be produced by sensing, or otherwise determining, signals used by primary users and developing signals using a modulation scheme or other signal parameters that provides little disruption to primary users. These techniques make available to users unused and/or underused portions of the radio spectrum, such as whitespaces between television channels. The new signals may be generated by software defined radios within the computing devices or by switching between modulation schemes supported by conventional wireless network interface card.

  • Patent number: 8797975
    Abstract: In a femtocell basestation of a cellular communications network, there is a potential difficulty that the basestation may be unable to select a scrambling code for its transmissions, without the risk of interference with other basestations using the same scrambling code. The femtocell basestation receives from a management system a list comprising at least one allowed scrambling code for femtocell basestations, and also detects, in information broadcast by at least one macrocell basestation, at least one allowed scrambling code available in an area containing the basestation. If it is determined that use of each scrambling code that is allowed and is available in an area containing the basestation would cause interference with another femtocell basestation, a parameter is set to ensure that a user equipment would perform a location update when moving between the coverage areas of said basestation and the other femtocell basestation. The parameter may be a MIB and/or SIB value tag.

  • Patent number: 8787838
    Abstract: The suitability of a fixed or current mobile operating location for the receiver (19) in a data memory (13, 15) for picking up the consumption data (12) transmitted by a data radio channel in a wireless local data capture system (11) from consumption points (14) to a data memory (13, 15) can easily and reliably be qualitatively assessed in situ or for the purpose of remote diagnosis by virtue of a channel scan being initiated and the memory receiver (17) performing an RSSI measurement, which is preferably presented as a histogram (20) against current channel use. This renders permanent sources of interference and link budget problems in the data radio (particularly UHF) channel and also temporary sources of interference and collision problems in this channel identifiable and thereby avoids costly receiver location changes, without use of radio-specific specialist personnel, after a site has previously been selected for the receiver installation only empirically but inexpediently.

  • Patent number: 8768371
    Abstract: A technique for a secondary communication system to utilize spectrum designated to another (or primary) communication system is provided. By ranking a plurality of secondary base stations based on base station transmit power, calculated required transmit power and path loss, a set of criteria is developed for selecting a highest ranked secondary base station for operation within a primary's spectrum. The ranking may be adapted based on mobility of the secondary's subscriber; and as such the secondary system communicates within the primary's spectrum using the adaptively ranked base stations. Channel selection may also be ranked. The technique and apparatus allows a cognitive radio (CR) network to operate within an incumbent network's spectrum.
