Methods and Apparatus for Managing Network Signaling

1 . An apparatus, comprising:

at least one processor; and

at least one memory storing a program of instructions;

wherein the program of instructions is configured, with the at least one memory and the at least one processor to cause the apparatus to perform actions comprising at least:

performing channel state information measurements in each of one or more measurement subframes, wherein the measurement subframes are specified based on a configuration of the apparatus;

receiving a channel state information triggering uplink grant designating a measurement subframe for which measurement information is to be reported, wherein the designated measurement subframe lies at least a specified number of subframes before an uplink communication subframe in which the measurement information is to be reported; and

transmitting a communication state information report signal in response to the channel state information triggering uplink grant.

2 . The apparatus of claim 1 , wherein the specified number of subframes is greater than 4.

3 . The apparatus of claim 1 , wherein the configuration of the apparatus is performed based on receiving signaling from a base station directing the apparatus to designate specified subframes as measurement subframes.

4 . The apparatus of claim 3 , wherein the signaling comprises a measurement trigger transmitted by the base station in at least one of an uplink and a downlink grant.

5 . The apparatus of claim 3 , wherein the configuration of the apparatus defines a pattern of measurement subframes.

6 . The apparatus of claim 5 , wherein the pattern of measurement subframes is received using radio resource control signaling.

7 . An apparatus, comprising:

at least one processor; and

at least one memory storing a program of instructions;

wherein program of instructions is configured, with the at least one memory and the at least one processor to cause the apparatus to perform actions comprising at least:

sending a channel state information triggering uplink grant designating a measurement subframe for which measurement information is to be reported by a user equipment, wherein the designated measurement subframe lies at least a specified number of subframes before an uplink communication subframe in which the measurement information is to be reported.

8 . The apparatus of claim 7 , wherein the functions further comprise specifying measurement subframes during which measurements are to be performed by the user equipment.

9 . The apparatus of claim, wherein specifying measurement subframes comprises signaling the user equipment to identify one or more measurement subframes.

10 . The apparatus of claim 7 , wherein at least one measurement subframe is specified by a measurement trigger transmitted in one of an uplink and a downlink grant.

11 . The apparatus of claim 8 , wherein specifying measurement subframes comprises specifying a pattern of measurement subframes using radio resource signaling.

12 . The apparatus of claim 7 , wherein the functions further comprise specifying reporting instants for the user equipment, wherein a reporting instant comprises a subframe in which the user equipment is directed to perform uplink reporting of channel state information.

13 . A method comprising:

sending a channel state information triggering uplink grant designating a measurement subframe for which measurement information is to be reported by a user equipment wherein the designated measurement subframe lies at least a specified number of subframes before an uplink communication subframe in which the measurement information is to be reported.

14 . The method of claim 13 , further comprising specifying measurement subframes during which measurements are to be performed by the user equipment.

15 . The method of claim 13 , wherein at least one measurement subframe is specified by a measurement trigger transmitted in one of an uplink and a downlink grant.

16 . The method of claim 14 , wherein specifying measurement subframes comprises specifying a pattern of measurement subframes using radio resource signaling.

17 . The method of claim 13 , wherein the functions further comprise specifying reporting instants for the user equipment, wherein a reporting instant comprises a subframe in which the user equipment is directed to perform uplink reporting of channel state information.

18 . A non-transitory computer readable storage medium storing a program of instructions, execution of which by a processor configures an apparatus to perform actions comprising at least:

performing channel state information measurements in each of one or more measurement subframes, wherein the measurement subframes are specified based on a configuration of the apparatus;

receiving a channel state information triggering uplink grant designating a measurement subframe for which measurement information is to be reported, wherein the designated measurement subframe lies at least a specified number of subframes before an uplink communication subframe in which the measurement information is to be reported; and

transmitting a communication state information report signal in response to the channel state information triggering uplink grant.

19 . The computer readable storage medium of claim 18 , wherein the configuration of the apparatus is performed based on signaling by a base station directing the apparatus to designate specified subframes as measurement subframes.

20 . The computer readable storage medium of claim 18 , wherein the signaling comprises a measurement trigger transmitted by the base station in at least one of an uplink and a downlink grant.

21 . The computer readable storage medium of claim 18 , wherein the configuration of the apparatus defines a pattern of measurement subframes.

22 . The computer readable storage medium of claim 21 , wherein the pattern of measurement subframes is received using radio resource control signaling.
