摘要： A transmission initiation interval timing structure is used in combination with a lower layer timing structure, e.g., physical layer timing structure. A device selects a subset of packet transmission initiation intervals and then limits initiation of packet transmission to those intervals thereby reducing the potential for collisions. Packet transmission may occur outside the initiation interval in which the transmission is initiated. In some embodiments, packet transmission length is intentionally limited to sizes which can be transmitted in a fraction of the amount of time the physical layer allows a single device to continuously transmit, e.g., in an amount of time which is equal to or less than the duration of a packet transmission initiation interval. This increases the probability that multiple devices will be able to successfully transmit small packets at short intervals on a regular basis even when carrier sensing techniques are used.

摘要： The present invention discloses, in a two-way radio frequency (RF) communications system having at least one repeater, a plurality of channels, and a plurality of subscriber units, a repeater receives a message that identifies a channel that is selected to serve as a rest channel for the system. The channel that is currently serving as the rest channel for the system is monitored by subscriber units that are idle in the system. If the repeater determines that the channel selected to serve as the rest channel is hosted by the repeater, the repeater periodically transmits an identity of the channel as the channel currently serving as the rest channel on at least the channel.

摘要： An autonomously dispersed type wireless network is suitably formed with communication stations avoiding collision of beacons transmitted one to another. In the event that the range of reach of airwaves change and a receivable state is created and beacons collide, a communication station changes the beacon transmission position of itself in response to receiving a beacon from another station at a timing immediately prior to transmission to its own beacon. Also, in the event that beacon collision is exposed due to emergence of a new communication which can perform reception from two systems out of airwave range of each other, the newly-participating station requests one of the communication stations of which the beacons are colliding to change the beacon transmission timing.

摘要： A method and system for assigning uplink (UL) slots to optimize time division duplex (TDD) UL power. In order to assure proper power control gain, UL slots are judiciously allocated close to the beacon slot. The UL slots may be allocated based on channel sensing. All users are sorted in the order of reducing fading losses. Sorting information is also used to allocate the UL slots. The UL slots may also be allocated based on signal interference information, code usage availability estimates and spread signal interference values. Alternatively, block error rate (BLER) and signal to interference ratio (SIR) measurements may be used to allocate the UL slots.

摘要： Systems and methodologies are described that facilitate allocation of uplink acknowledgement (ACK) resources for a wireless communication system. Various aspects described herein facilitate explicit creation and transmission of a bundled assignment of downlink communication resources and uplink resources for ACK transmission, thereby facilitating overhead-efficient ACK allocation for users that can communicate pursuant to a persistent resource assignment without requiring scheduling information from an associated control channel. Additionally, indexing schemes for uplink ACK resources are provided herein to facilitate ACK allocation for systems in which both scheduled and persistent users can communicate at a common transmission time interval (TTI).

摘要： In a data communication network (SYS) a first and second network site (BSS), (MS) communicate by sending a first data transmission (DT1) from the first network site (BSS) to a second network site (MS) and by sending a second data transmission (DT2) from said second network site (MS) to said first network site (BSS). In accordance with the invention data transmission characteristics (DTC1) of said first data transmission (DT1) are determined and radio resources for said data transmission (DT2) are allocated based on the determined first data transmission characteristics (DTC1). Thus, the radio resources for the second data transmission (DT2) are correlated with characteristics of the first data transmission (DT1) and thus delays in the data transmission between the first and second network site (BSS, MS) can be avoided. The invention finds particular application in data transmission networks, for example in a TCP/IP network, in which a link layer protocol context, for example a Temporary Block Flow (TBF), has to be set up for the data transmissions. In such applications the invention can reduce the data packet transmission delay by avoiding unnecessary TBF setup/tearing down procedures.

摘要： A resource allocation method in a multiuser-multiple-input multiple-output/orthogonal frequency division multiple access (MIMO/OFDMA) system. In the multiuser-MIMO/OFDMA system feedback information is received from terminals. A channel gain and a transmission rate for each user are determined using the feedback information. An average channel gain for each user is computed according to the channel gain. The average number of bits for each user is determined according to the average channel gain. The number of subchannels for each user is computed according to the average number of bits for each user. At least one subchannel is allocated to each user according to the number of subchannels for each user. A modulation scheme for each of the at least one subchannel is determined. The resource allocation method adaptively allocates subchannels and bits according to channel environment, thereby considerably improving frequency use efficiency as well as a power gain.
