Abstract

Embodiments of the disclosure relate to operational association between communication devices in the presence of a link-budget imbalance between an upstream link and a downstream link at one of the communication devices. The association relies on a request for a narrowband resource block sent form the communication device having the link-budget imbalance to a remote communication device that can schedule and/or allocate the narrowband resource block. The request can be modulated according to an on-off keying modulation scheme or can be encoded according to a multi-repetition encoding scheme. In response to the narrowband resource block being allocated, an association request can be sent to the remote communication device in the narrowband resource block.

First claim

What is claimed is:

1 . An apparatus for wireless telecommunication, comprising:
at least one memory device having programmed instructions; and at least one processor functionally coupled to the at least one memory device and configured to execute the programmed instructions, and in response to execution of the programmed instructions, further configured to:
determine that a response to an association request is not received at the apparatus;
generate a request for a narrowband resource block allocation in a channel having a predetermined spectral width;
send a request for a narrowband resource block allocation in the channel;
receive resource allocation information indicative of an identification code and a narrowband resource block within the channel;
determine that the identification code corresponds to the apparatus; and
send a second association request in the narrowband resource block.

2 . The apparatus of claim 1 , wherein the at least one processor is further configured to generate a frame associated with the request for a narrowband resource block, the frame comprising a legacy preamble and a payload field modulated according to one of on-off keying (OOK), amplitude shift keying (ASK), frequency shift keying (FSK), or repetition coding.

3 . The apparatus of claim 2 , wherein the at least one processor is further configured to modulate the frame using on-off keying, the payload field comprising a preamble, a medium access control (MAC) header, a content field, and a validation field,
wherein the MAC header conveys that the frame corresponds to the request for the narrowband resource block, the content field conveys the identification code, and the validation field corresponds to a frame check sequence of the MAC header and the content field.

4 . The apparatus of claim 1 , wherein the at least one processor is further configured to generate a frame associated with the request for a narrowband resource block, the frame comprising a legacy preamble, a non-legacy preamble, and a payload field.

5 . The apparatus of claim 4 , wherein the at least one processor is further configured to encode the frame using an eight-time coding scheme, the payload field comprising a medium access control (MAC) header, a content field, and a validation field,
wherein the MAC header conveys that the frame corresponds to the request for the narrowband resource block, the content field conveys the identification code, and the validation field corresponds to a frame checksum of the MAC header and the content field.

6 . The apparatus of claim 1 , wherein the second association request is sent to an access point operating according to a protocol of IEEE 802.11ax standard, the predetermined spectral width of the channel is about 20 MHz, and the narrowband resource block spans 2.5 MHz.

7 . A method for wireless communication, comprising:
generating, by a communication device having at least one processor and at least one memory device, an association request in a resource block spanning a spectral width of a channel; sending, by the communication device, the association request to a remote communication device; determining that a response to the association request is not received at the computing device from the remote communication device; generating, by the communication device, a request for a narrowband resource block allocation within the channel; sending, by the communication device, a request for a narrowband resource block allocation within the channel to the remote communication device; receiving, by the communication device, from the remote communication device, resource allocation information indicative of an identification code and a narrowband resource block within the channel; determining, by the communication device, that the identification code corresponds to the communication device; and sending a second association request in the narrowband resource block to the remote communication device.

8 . The method of claim 7 , wherein generating the request for the narrowband resource block allocation comprises generating, by the communication device, a frame including a legacy preamble and a payload field modulated according to one of on-off keying (OOK), amplitude shift keying (ASK), frequency shift keying (FSK), or repetition coding.

9 . The method of claim 7 , wherein generating the frame comprises modulating the frame using on-off keying, the payload field including a preamble, a medium access control (MAC) header, a content field, and a validation field,
wherein the MAC header conveys that the frame corresponds to the request for the narrowband resource block, the content field conveys the identification code, and the validation field corresponds to a frame checksum of the MAC header and the content field.

10 . The method of claim 7 , wherein generating the request for the narrowband resource block allocation comprises generating, by the communication device, a frame comprising a legacy preamble, a non-legacy preamble, and a payload field.

11 . The method of claim 10 , wherein generating the frame comprises encoding the frame using an eight-time coding scheme, the payload field comprising a medium access control (MAC) header, a content field, and a validation field,
wherein the MAC header conveys that the frame corresponds to the request for the narrowband resource block, the content field conveys the identification code, and the validation field corresponds to a frame checksum of the MAC header and the content field.

12 . At least one computer-readable non-transitory storage medium having instructions encoded thereon that, in response to execution, cause a device to perform operations comprising:
generating an association request in a resource block spanning a spectral width of a channel; sending the association request to a remote communication device; determining that a response to the association request is not received at the computing device from the remote communication device; generating a request for a narrowband resource block allocation within the channel; sending a request for a narrowband resource block allocation within the channel to the remote communication device; receiving from the remote communication device, resource allocation information indicative of an identification code and a narrowband resource block within the channel; determining that the identification code corresponds to the communication device; and sending a second association request in the narrowband resource block to the remote communication device.

13 . The at least one computer-readable non-transitory storage medium of claim 12 , wherein generating the request for the narrowband resource block allocation comprises generating a frame including a legacy preamble and a payload field modulated according to one of on-off keying (OOK), amplitude shift keying (ASK), frequency shift keying (FSK), or repetition coding.

14 . The at least one computer-readable non-transitory storage medium of claim 13 , wherein generating the frame comprises modulating the frame using on-off keying, the payload field including a preamble, a medium access control (MAC) header, a content field, and a validation field,
wherein the MAC header conveys that the frame corresponds to the request for the narrowband resource block, the content field conveys the identification code, and the validation field corresponds to a frame checksum of the MAC header and the content field.

15 . The at least one computer-readable non-transitory storage medium of claim 12 , wherein generating the request for the narrowband r
