摘要： A communication system is used to transmit and receive data on a plurality of relatively narrow-band signals and wideband signals. The two signal types share a common electromagnetic spectrum by employing spreading gain and maintaining orthogonality between simultaneously transmitted wideband and narrow-band signals. Signal orthogonality is maintained by selectively choosing orthogonal codes and aligning or spacing a wideband carrier frequency with respect to the narrow-band carrier frequencies in accordance with the ratio of the wideband to the narrow-band chip frequencies. A pilot signal is preferably transmitted contemporaneously with the transmission of the first spread signal, and a control date signal, associated with a plurality of users on the first bandwidth, is transmitted on a common control channel using a single Walsh code that is shared by a plurality of users in a TDMA protocol.

摘要： In some embodiments, only one multicast connection identifier is used in a WiMAX network per zone. This may result in power savings because it is not necessary for the mobile station to query a base station to obtain the correct information about how to locate desired channels in a WiMAX multicast. Instead, the mobile station may be maintained in a lower power consumption mode in which it need not transmit, but only receives information. This is because the mobile station has all the information it needs about what channels are available and can simply tune using a logical media channel identifier to the appropriate channel to receive the desired content without having to transmit a message to the base station to identify the correct channel.

摘要： A system and method for optimizing random access control, and for optimizing transmission efficiency of data packets over reverse common channels between access terminals and a base station, in a wireless communications system. In the communications system, at least one of the access terminals is adapted to transmit at least a portion of an access data packet to the base station, and the base station is adapted to receive the portion of the access data packet and, in response, to transmit a message for receipt by the plurality of access terminals which indicates receipt of the access data packet portion by the base station and identifies the access terminal from which said access data packet portion is received. The message can control the other access terminals to refrain from transmitting an access data packet, while indicating receipt of the access data packet portion to the certain access terminal from which the access data packet portion had been transmitted. The base station can also provide power control signals to control transmission power of that certain access terminal, and to control that certain access terminal to transmit over certain reverse channels. Accordingly, interference between access data packets being transmitted by multiple access terminals and being received in the same time slot by a base station in a wireless communications system can also be minimized.

摘要： A communication system is used to transmit and receive a plurality of relatively narrow-band signals and wideband signals. The two signal types share a common electromagnetic spectrum by employing spreading gain and maintaining orthogonality between simultaneously transmitted wideband and narrow-band signals. Signal orthogonality is maintained by selectively choosing orthogonal codes and aligning or spacing a wideband carrier frequency with respect to the narrow-band carrier frequencies in accordance with the ratio of the wideband to the narrow-band chip frequencies. A pilot signal is preferably transmitted contemporaneously with the transmission of the first spreaded signal, and a control data signal, associated with a plurality of users on the first bandwidth, is transmitted on a common control channel using a single Walsh code that is shared by a plurality of users in a TDMA protocol. Further, if the length of the message intended for transmission by the wideband transceivers is below a message length threshold, the message can be transmitted using a common access channel shared by the wideband transceivers. Still further, by adapting the data transmission rate, in response to the data error rate and transmitter power level, the transmission range and/or the data transmission rate can be optimized.

摘要： Apparatuses and methods for supporting multicast device-to-device communications are described herein. A user equipment (UE) may transmit a request to a serving evolved Node B (eNodeB) for permission to transmit to a group of peer UEs. The UE may receive a resource assignment in response to the request. The resource allocation assignment may specify a group identifier. The group identifier may identify a group including the UE and the group of peer UEs. The UE may transmit a multicast transmission to the group of peer UEs using a resource assigned by the eNodeB with the resource assignment.

摘要： The various inventive embodiments relate to arrangement of information elements (IEs) for persistent and/or dynamic allocations in a wireless broadband network and include optimization techniques to eliminate the repetitive information fields from the downlink (DL)-Persistent-IEs, uplink (UL)-Persistent-IEs, DL-IEs, and UL-IEs. Elimination of repetitive information fields reduces MAP overhead. In addition embodiments relate to methods to use the same hybrid automatic repeat request (HARQ) region to contain persistent as well as non-persistent allocations. The use of the same HARQ region for persistent as well as non-persistent allocations further reduces the MAP overhead as it requires a single header to define the HARQ region instead of the two headers that are required to define two different HARQ regions: one for persistent allocation and the second one for non-persistent allocations.

摘要： Technology for configuring, activating and deactivating component carriers in carrier aggregation is disclosed. One method comprises configuring a Primary Component Carrier (PCC) as a primary component carrier pair comprising a downlink primary component carrier (DL PCC) and an uplink primary component carrier (UL PCC). At least one Secondary Component Carrier is configured at the eNode B as a secondary component carrier pair comprising a downlink secondary component carrier (DL SCC) and an uplink component carrier (UL SCC) based on a carrier aggregation capability of a selected UE. An activation and deactivation of each SCC is communicated from the eNode B to the UE with a bitmap carried by a media access control (MAC) control element. A bit set to “1” denotes activation of a corresponding SCC at the UE. A bit set to “0” denotes deactivation of a corresponding SCC at the UE.
