Abstract

There is provided an apparatus for a terminal, wherein the apparatus has means for receiving, from a network entity, an indication of a discontinuous transmission configuration associated with the network entity, wherein the indication indicates to the terminal that the network entity will refrain from providing downlink transmissions during a time period associated with the discontinuous transmission configuration. The apparatus also has means for determining whether at least one of: a reception at the terminal, and a transmission from the terminal, will at least partially overlap with the time period associated with the discontinuous transmission configuration. The apparatus also has means for, when it is determined that at least one of: the reception and the transmission will at least partially overlap with the time period, performing an action associated with the determined reception and/or transmission.

First claim

1 - 61 . (canceled)

62 . An apparatus for a terminal, the apparatus comprising: one or more processors, and memory storing instructions that, when executed by the one or more processors, cause the apparatus to perform:
receiving, from a network entity, an indication of a discontinuous transmission configuration associated with the network entity, wherein the indication indicates to the terminal that the network entity will refrain from providing downlink transmissions during a time period associated with the discontinuous transmission configuration; determining whether at least one of: a reception at the terminal, and a transmission from the terminal, will at least partially overlap with the time period associated with the discontinuous transmission configuration; and when it is determined that at least one of: the reception and the transmission will at least partially overlap with the time period, performing an action associated with the determined reception and/or transmission.

63 . The apparatus according to claim 62 , wherein the performing an action comprises applying a skipping of the determined reception and/or transmission, such that the terminal refrains from performing operations associated with the determined reception and/or transmission.

64 . The apparatus according to claim 62 , wherein the performing an action comprises skipping measurements to be performed by the terminal, when the determined reception at the terminal comprises at least one reference signal.

65 . The apparatus according to claim 62 , wherein the performing an action comprises performing measurements on reference signal resource elements that do not overlap with the time period associated with the discontinuous transmission configuration.

66 . The apparatus according to claim 62 , wherein the performing an action comprises postponing a reception and/or transmission operation associated with the determined reception and/or transmission.

67 . The apparatus according to claim 62 , wherein the performing an action comprises changing a timer associated with the determined reception and/or transmission.

68 . The apparatus according to claim 67 , wherein the changing the timer comprises, at least one of: suspending the timer, ignoring an expired timer, and extending a timer.

69 . The apparatus according to claim 62 , wherein the discontinuous transmission configuration comprises a resource pattern, in the time domain,
wherein the resource pattern comprises at least one of: a pattern time duration, a time offset, a repetition period, and a micro-discontinuous transmission configuration.

70 . The apparatus according to claim 69 , wherein the resource pattern comprises at least one of: information about the applicability of the resource pattern to one or more channels and/or signals, and operations to be performed by the terminal related to the one or more channels and/or signals.

71 . The apparatus according to claim 62 , wherein the indication is received, via a broadcast signalling, to terminals in a cell, wherein the terminal is within coverage of the cell, the cell being provided by the network entity.

72 . The apparatus according to claim 62 , the apparatus caused to perform:
receiving a plurality of discontinuous transmission configurations associated with the network entity, wherein the discontinuous transmission configuration is one of the plurality of discontinuous transmission configurations.

73 . The apparatus according to claim 72 , wherein the plurality of discontinuous transmission configurations is received via: radio resource signalling, a medium access control control element, downlink control information, or system information.

74 . The apparatus according to claim 62 , the apparatus caused to perform: receiving, from the network entity, an indication to activate the discontinuous transmission configuration.

75 . The apparatus according to claim 62 , the apparatus caused to perform:
wherein physical downlink shared channel aggregation is configured for the terminal by the network entity, determining whether a first redundant version of the determined reception is at least partially overlapped with the time period associated with the discontinuous transmission configuration; and when is it determined that the first redundant version is at least partially overlapped, skipping the reception of all redundant versions associated with the determined reception.

76 . The apparatus according to claim 62 , the apparatus caused to perform:
wherein physical downlink shared channel aggregation is applied by the network entity, determining whether at least one redundant version other than the first redundant version of the determined reception is overlapped with the time period associated with the discontinuous transmission configuration; and when is it determined that at least one redundant version other than the first redundant version is overlapped, adjusting an aggregation level associated with the determined reception.

77 . The apparatus according to claim 62 , the apparatus caused to perform:
receiving, from a network entity, a further indication of a discontinuous reception configuration associated with the terminal.

78 . The apparatus according to claim 77 , the apparatus caused to perform:
determining whether a transmission from the terminal, will at least partially overlap with a further time period associated with the discontinuous reception configuration; and when it is determined that the transmission will at least partially overlap with the further time period, performing a further action associated with the determined reception and/or transmission.

79 . An apparatus for a network entity, the apparatus comprising: one or more processors, and memory storing instructions that, when executed by the one or more processors, cause the apparatus to perform:
determining a discontinuous transmission configuration associated with the network entity; providing, to a terminal, an indication of the determined discontinuous transmission configuration associated with the network entity; and refraining from providing downlink transmissions to the terminal during a time period associated with the discontinuous transmission configuration.

80 . The apparatus according to claim 79 , wherein the discontinuous transmission configuration associated with the network entity is: being used by the network entity, or is scheduled to be used by the network entity.

81 . A method performed by a terminal, the method comprising:
receiving, from a network entity, an indication of a discontinuous transmission configuration associated with the network entity, wherein the indication indicates to the terminal that the network entity will refrain from providing downlink transmissions during a time period associated with the discontinuous transmission configuration; determining whether at least one of: a reception at the terminal, and a transmission from the terminal, will at least partially overlap with the time period associated with the discontinuous transmission configuration; and when it is determined that at least one of: the reception and the transmission will at least partially overlap with the time period, performing an action associated with the determined reception and/or transmission.
