Abstract:
A method of operating a long term evolution (LTE) communication system on a shared frequency spectrum is disclosed. A user equipment (UE) is initialized on an LTE frequency band. A base station (eNB) monitors the shared frequency spectrum to determine if it is BUSY. The eNB transmits to the UE on the shared frequency spectrum if it is not BUSY. The eNB waits for a first time if it is BUSY and directs the UE to vacate the shared frequency spectrum after the first time.
Abstract:
A method of operating a wireless communication system is disclosed. The method includes communicating by a first data frame having a first transmit time interval with a first wireless transceiver and communicating by a second data frame having a second transmit time interval different from the first transmit time interval with a second wireless transceiver. Data is transferred between the first data frame and the second data frame.
Abstract:
A method of operating a wireless communication system is disclosed. The method includes receiving first and second parallel data streams. The first data stream is converted to a first frequency-domain data stream by a discrete Fourier transform (DFT) having NDFT0 size, where NDFT0 is a positive integer. The second data stream is converted to a second frequency-domain data stream by a DFT having NDFT1 size, where NDFT1 is a positive integer. The first and second frequency-domain data streams are mapped to respective subcarriers.
Abstract:
In at least some embodiments, a wireless networking system is provided. The wireless networking system includes a base-station and a plurality of user devices in communication with the base-station. The base-station selectively assigns each user device to one of a first group and a second group. Also, the base-station selectively assigns each user device to an uplink synchronized state and an uplink non-synchronized state. The base-station allocates a unique reduced identifier to each user device in the uplink synchronized state, but does not allocate unique reduced identifiers to user devices in the non-synchronized state.

Abstract:
A method of operating a wireless communication system is disclosed. The method includes receiving respective downlink transmissions at N second transceivers from a first transceiver, where N is a positive integer greater than 1. The reception acknowledgement signals by the N second transceivers are combined into a single reception acknowledgement signal and transmitted to the first transceiver.
Abstract:
A method of operating a wireless communication system is disclosed. The method includes receiving allocation information for a plurality of second wireless transceivers from a first wireless transceiver by one of the second wireless transceivers on a physical broadcast channel (PBCH). The one of the second wireless transceivers decodes the allocation information for the plurality of second wireless transceivers. The one of the second wireless transceivers receives procedural information on a physical downlink control channel (PDCCH) in response to the decoded allocation information
Abstract:
A transport block size (TBS) of a first uplink message (RACH Msg3) transmitted on a Physical Uplink Shared Channel (PUSCH) during a random access procedure in a User Equipment (UE) accessing a radio access network may be determined by receiving a pathloss threshold parameter. A downlink pathloss value indicative of radio link conditions between the UE and a base station (eNB) serving the UE is then determined. A smaller value of TBS is selected from a set of TBS values if the determined pathloss value is greater than an operating power level of the UE minus the pathloss threshold parameter. A larger value of TBS is selected if the pathloss value is less than the operating power level of the UE minus the pathloss threshold parameter and the TBS required to transmit the RACH Msg3 exceeds the smaller TBS value.
