Abstract
Certain aspects of the present disclosure relate to methods and apparatus for allocating resources for the transmission of scheduling requests based on UE traffic profiles. In one embodiment, a base station determines, for one or more user equipments (UEs), a type of traffic to be exchanged between the one or more UEs and the base station. The base station allocates resources for the one or more UEs to use for sending a scheduling request based, at least in part, on the type of traffic associated with each of the one or more UEs. The base station signals an indication of the allocated resources to each of the one or more UEs.
Claims24
A method of wireless communication by a base station (BS), comprising:
- determining, for one or more user equipments (UEs), a type of traffic to be exchanged between the one or more UEs and the BS;
- allocating resources for the one or more UEs to use for sending a scheduling request based, at least in part, on the type of traffic associated with each of the one or more UEs;
- signaling an indication of the allocated resources to each of the one or more UEs;
- and
- receiving a scheduling request from at least one of the one or more UEs on the allocated resources, wherein:
- at least one of the received scheduling requests comprises one bit requesting resources for an uplink transmission and a plurality of bits specifying additional information regarding the uplink transmission;
- and
- the additional information comprises a buffer status, a packet size, and a packet lifetime of the uplink transmission.
A method of wireless communication by a user equipment (UE), comprising:
- determining one or more resources in a control channel assigned to the UE for sending a scheduling request to a base station (BS), wherein the one or more resources are based, in part, on a type of traffic to be exchanged between the UE and the BS;
- determining a plurality of types of information for an uplink transmission to include in the scheduling request based, at least in part, on the type of traffic and an amount of the one or more resources;
- and
- transmitting a scheduling request in the assigned one or more resources to request resources for the uplink transmission, wherein:
- the scheduling request comprises one bit for requesting the resources for the uplink transmission and additional bits comprising the plurality of types of information;
- and
- the plurality of types of information comprise a buffer status, a packet size, and a packet lifetime of the uplink transmission.
An apparatus for wireless communication, comprising:
- means for determining, for one or more user equipments (UEs), a type of traffic to be exchanged between the one or more UEs and the apparatus;
- means for allocating resources for the one or more UEs to use for sending a scheduling request based, at least in part, on the type of traffic associated with each of the one or more UEs;
- means for signaling an indication of the allocated resources to each of the one or more UEs;
- and
- means for receiving a scheduling request from at least one of the one or more UEs on the allocated resources, wherein:
- at least one of the received scheduling requests comprises one bit requesting resources for an uplink transmission and a plurality of bits specifying additional information regarding the uplink transmission;
- and
- the additional information comprises a buffer status, a packet size, and a packet lifetime of the uplink transmission.
An apparatus for wireless communication, comprising:
- means for determining one or more resources in a control channel assigned to the apparatus for sending a scheduling request to a base station (BS), wherein the one or more resources are based, in part, on a type of traffic to be exchanged between the apparatus and the BS;
- means for determining a plurality of types of information for an uplink transmission to include in the scheduling request based, at least in part, on the type of traffic and an amount of the one or more resources;
- and
- means for transmitting a scheduling request in the assigned one or more resources to request resources for the uplink transmission, wherein:
- the scheduling request comprises one bit for requesting the resources for the uplink transmission and additional bits comprising the plurality of types of information;
- and
- the plurality of types of information comprise a buffer status, a packet size, and a packet lifetime of the uplink transmission.
