An N=3 frequency plan for 60 degree sector transmit sector receive (STSR) cell sites is based upon dividing available channels into 18 frequency groups.

The acknowledgement bitmap includes a sector acknowledgement bit.

The receiving device is equipped with a narrow-beam antenna.

Another method includes receiving a cross-subframe assignment in a first subframe.

Transmission of a message following receipt of an acknowledgement occurs only over a transmit sector containing the received acknowledgement signal.

A method and apparatus for transmitting and receiving a SectorParameters message in an Active state is provided.

In a cellular type communication system a sector antenna (12) provides coverage of a sector with a relatively low receive gain.

The transmitter transmits the acknowledgement bitmap for each sector to the transmitting communication device.

The terminal determines an ACK/NACK acknowledgement based on said ACK/NACK state, and transmits the ACK/NACK acknowledgement in an uplink subframe.

When the sector indication is received, a modulo function operates on entries of the look-up table in order to determine the memory location associated with the sector indication.

After this, the reception side simultaneously performs identification of a sector by detecting a sector unique code and acquisition of cell unique information by demodulating a cell unique code.

Food business operators receiving batches must date-stamp the document on receipt of the batch or record the date of receipt in another manner.

G4S provides security, guarding and reception services to customers in both the public and private sectors.

Good positive receiving first touches into space to attack another sector.

The method may also include receiving a nominal grant in the first subframe that targets an identified subframe to which a second TPC command is to be applied.
