Contention-based co-existence on a shared communication medium
First Claim
Patent Images
1. A communication method, comprising:
- contending for access to a communication medium for a first transmission opportunity (TXOP) spanning a first duration;
transmitting a first channel reservation message reserving the communication medium for the first TXOP;
transmitting during the first TXOP a scheduling grant to an access terminal granting the access terminal uplink resources for a second TXOP spanning a second duration;
contending for access to the communication medium for the second TXOP;
transmitting a second channel reservation message reserving the communication medium for the second TXOP; and
receiving uplink signaling from the access terminal over the granted uplink resources during the second TXOP.

Abstract
Techniques for managing contention on a shared communication medium are disclosed. Various techniques are provided to facilitate aspects such as reference signaling, downlink medium access, uplink medium access, resource reuse, channel structures, acknowledgment schemes, fairness, acquisition, random access, paging, mobility, inter-operator mitigation, and so on for a frame structure implemented on the shared communication medium.

6. A communication apparatus, comprising:
-
at least one processor; at least one memory coupled to the at least one processor, the at least one processor and the at least one memory being configured to contend for access to a communication medium for a first transmission opportunity (TXOP) spanning a first duration; and at least one transceiver configured to; transmit a first channel reservation message reserving the communication medium for the first TXOP; and transmit during the first TXOP a scheduling grant to an access terminal granting the access terminal uplink resources for a second TXOP spanning a second duration wherein the at least one processor and the at least one memory are further configured to contend for access to the communication medium for the second TXOP; and wherein the at least one transceiver is further configured to; transmit a second channel reservation message reserving the communication medium for the second TXOP; and receive uplink signaling from the access terminal over the granted uplink resources during the second TXOP. - View Dependent Claims (7, 8, 9, 10)

11. A communication method, comprising:
-
receiving a first channel reservation message reserving the communication medium for a first transmission opportunity (TXOP) spanning a first duration; receiving a scheduling grant from an access point during the first TXOP, wherein the scheduling grant grants uplink resources for a second TXOP spanning a second duration; identifying uplink resources corresponding to the scheduling grant in the second TXOP; receiving a second channel reservation message reserving the communication medium for the second TXOP; and transmitting uplink signaling to the access point over the identified uplink resources during the second TXOP. - View Dependent Claims (12, 13, 14, 15, 16)
