Abstract
Official abstract text for this publication.
An access point includes an address management part, a transmission prohibition management part, and a transmission part. The address management part broadcasts a group address of a group set for terminals which are able to perform preferential exchange of data frames during a service period to terminals that are members of the group among the terminals under control thereof. The transmission prohibition management part generates a transmission prohibition frame including a first field storing a time length of the service period and a second field storing the group address. The transmission part transmits a transmission prohibition signal including the transmission prohibition frame to the terminals.
First claim
Opening claim text (preview).
1 . An access point, comprising a processor with hardware configured to: broadcast a group address of a group set for terminals which are able to perform preferential exchange of data frames during a service period to terminals that are members of the group among the terminals under control thereof; generate a transmission prohibition frame including a first field storing a time length of the service period and a second field storing the group address; and a transmit a transmission prohibition signal including the transmission prohibition frame to the terminals. 2 . The access point according to claim 1 , wherein the first field is a duration field, and the second field is a receiving station address (RA) field. 3 . The access point according to claim 1 , wherein the processor transmits the transmission prohibition frame at a start time of the service period or transmits the transmission prohibition frame so that exchange of the transmission prohibition frame with the terminals ends at the start time of the service period. 4 . The access point according to claim 1 , wherein the data frame is a data frame which requires low latency. 5 . The access point according to claim 1 , wherein the transmission prohibition frame is a trigger frame. 6 . A terminal, comprising a processor with hardware configured to: receive, from an access point, a transmission prohibition signal which includes a transmission prohibition frame including a first field storing a time length of a service period and a second field storing a group address of a group set for terminals which are able to perform preferential exchange of data frames during the service period; manage an address broadcast in advance from the access point; and perform control so that, when the group address is not an address broadcast in advance from the access point, a network allocation vector (NAV) of the time length of the service period stored in the first field is set, and when the group address is an address broadcast in advance from the access point, the NAV is not set.
