摘要: Systems and methods for decoding a transmission are provided. In some embodiments, a method performed by a wireless device comprises determining a plurality of Machine-Type Communications (MTC) Physical Downlink Control Channel (MPDCCH) transmission candidates to monitor. For at least one candidate of the plurality of MPDCCH transmission candidates, the method includes determining whether the candidate belongs to a first group of candidates or a second group of candidates. If the candidate belongs to the first group of candidates, the method includes attempting to decode the MPDCCH transmission using a Channel State Information (CSI)-based precoding scheme. If the candidate belongs to the second group of candidates, the method includes attempting to decode the MPDCCH transmission using a predetermined precoding scheme. This may allow a more robust precoding technique and can be considered as technique with a fallback solution for the cases in which the CSI is either missed or not reliable.

摘要: A network node is arranged to operate in a cell of a cellular communication system. The network node comprises an interface towards the cellular communication system where the interface is arranged to receive paging information for an idle user equipment, UE, a paging handler arranged to determine a mode of power saving for the UE, and to determine timing for a wake-up signal based on the determined mode and the received paging information, and a transmitter arranged to transmit the wake-up signal at the determined timing. A method of the network node comprises receiving paging information for an idle user equipment, UE, from the cellular communication system, determining a mode of power saving for the UE, determining timing for a wake-up signal based on the determined mode and the received paging information, and transmitting the wake-up signal at the determined timing.

摘要: A wireless communication device (12) is configured for random access to a wireless communication network (10). The N wireless communication device (12) transmits, to the wireless communication network (10), a random access preamble (14) in a random access channel occasion (18) that comprises one or more symbols. The wireless communication device (12) monitors for a response (20) to the random access preamble (14) within a response window (24). The response window (24) starts in an earliest control resource set (22-2) that begins at least a minimum number (Dmin) of symbols after the last symbol (18L) of the random access channel occasion (18), wherein the minimum number of symbols is greater than one.

摘要: A method performed by a network node in a communication network is provided. The method includes configuring a time-domain resource reservation for use in communication with a massive machine-type communication, mMTC, communication device when coexisting with a new radio system or a Long-Term Evolution system. The time-domain resource reservation includes a first bitmap having bits representing the resource reservation in consecutive slots and the first bitmap indicates one of a slot-level resource reservation and a symbol-level resource reservation. The method further includes signaling an indication of the time-domain resource reservation to the mMTC communication device. A method performed by a mMTC communication device is also provided.

摘要: Some embodiments include a method performed by a network node for indicating a modulation and coding scheme for a wireless device operating in a coverage enhancement mode, wherein the wireless device operates with a first modulation and coding scheme using physical downlink shared channel repetitions and with a second modulation and coding scheme without using physical downlink shared channel repetitions, and wherein the second modulation and coding scheme is a higher order of modulation and coding than the first modulation and coding scheme, the method comprising configuring, when physical downlink shared channel repetitions are not used, the downlink control information to indicate one or more parameters related to the second modulation and coding scheme, the indication comprising at least the modulation and coding scheme field of the first modulation and coding scheme and one or more downlink control information field bits which are used in relation to repetitions when repetitions of a physical downlink shared channel are used.

摘要: Systems and methods are disclosed herein that relate to the use of a Device-to-Device (D2D) sidelink, e.g., in a licensed spectrum, to assist with clear channel assessment in an unlicensed spectrum. In doing so, the hidden node problem and/or the exposed node problem can be mitigated. In some embodiments, a method of operation of a wireless device in a cellular communications network comprises performing a sidelink-assisted clear channel assessment (SLA-CCA) procedure to determine whether to transmit on an unlicensed channel. The SLA-CCA procedure is a Clear Channel Assessment (CCA) procedure that is assisted by information received by the wireless device from one or more other wireless devices over a D2D sidelink in a licensed spectrum. The method further comprises, upon determining to transmit on the unlicensed channel as a result of performing the SLA-CCA procedure, transmitting a transmission on the unlicensed channel.

摘要: Systems and methods are disclosed for triggering a long range extension mode of operation for a wireless device in a cellular communications network. In one preferred embodiment, the wireless device is a Machine Type Communication (MTC) device. In one embodiment, a node in the cellular communications network determines that the wireless device is to operate in the long range extension mode if there is difficulty in establishing communication between the wireless device and the cellular communications network. If the wireless device is to operate in the long range extension mode, the node activates one or more long range extension mechanisms with respect to the wireless device such that the wireless device operates in the long range extension mode. In this manner, the long range extension mode is selectively triggered for the wireless device.

摘要: Systems and methods are disclosed herein that relate to the use of signals in a licensed spectrum to assist with determining a status of an unlicensed channel(s) in an unlicensed spectrum. In some embodiments, a method of operation of a wireless device in a wireless system in which the wireless device transmits and/or receives in both a licensed spectrum and an unlicensed spectrum comprises attempting to detect a busy indication transmitted in the licensed spectrum. The busy indication is an indication that another wireless device is transmitting in the unlicensed spectrum. The method further comprises determining whether to transmit in the unlicensed spectrum based on whether the wireless device has detected a busy indication transmitted in the licensed spectrum. By using signals in the licensed spectrum, the hidden node problem and/or the exposed node problem in the unlicensed spectrum can be mitigated.
