[BLANKENSHIP, Yufei, BLANKENSHIP, Yufei, GRÖVLEN, Asbjörn, BLANKENSHIP, Yufei, GRÖVLEN, Asbjörn, BERGMAN, Johan] 164 83 Stockholm Methods and apparatus are disclosed for enabling a narrow-band MTC device to operate in a legacy LTE system having a wider system bandwidth. The physical downlink control channel for a narrow-band MTC device, also referred to as low-complexity physical downlink control channel (LC-PDCCH), has reduced bandwidth resource and can support no more than 6 physical resource blocks. The present application discloses how to allocate physical resource blocks (PRBs) for LC-PDCCH and physical downlink shared channel (PDSCH). The PRB allocation methods disclosed herein allow the MTC devices to derive the frequency location of the PDSCH PRBs from the frequency location of the LC-PDCCH PRBs and to soft-combine LC-PDCCH transmissions and PDSCH transmissions for performance improvement.

The radio network node (120) adds (A030) one or more received paging requests to a queue of paging requests and generates (A040) a first paging message and a parameter indicating existence of at least one second paging occasion. The radio network node (120) sends (A050), at a first paging occasion, the first paging message and sends (A055) the parameter to the wireless communication device (110). The wireless communication device receives (A060), at the first paging occasion, the first paging message and receives (A065) the parameter. The radio network node (120) generates (A070) a second paging message and sends (A080), at the second paging occasion, the second paging message.

The method comprises determining (102) a set of periodic subframes as a Paging Occasion (PO) subframe pattern. The method further comprises monitoring (104) a starting subframe of paging CSS for a Radio Network Temporary Identifier (RNTI). The starting subframe of paging CSS is determined as follows: a first subframe (SF0) (108), defined by the Paging Occasion subframe pattern, is used when SF0 is determined (106) to be a valid downlink subframe. A next valid downlink subframe after SF0 (110) is used when SF0 is determined (106) to be an invalid downlink subframe.

[HARRISON ROBERT MARK, GRÖVLEN ASBJÖRN, LIN ZHIPENG] SE Methods, a base station and a terminal device for two-step random access procedure are disclosed. According to an embodiment, the base station transmits a first message indicating a subcarrier spacing (SCS) of at least one of a preamble and a physical uplink shared channel (PUSCH) which are to be used for a second message in two-step random access procedure, through an air interface. The SCS of the PUSCH is the same as an SCS used for message 3 in four-step random access procedure. The base station receives the second message based on the SCS of the PUSCH through the air interface in two-step random access procedure.

The wireless communication device in particular is configured to generate a random access preamble signal that comprises multiple symbol groups, with each symbol group on a single tone during a different time resource, according to a frequency hopping pattern that hops the random access preamble signal from at least one of the symbols groups to an adjacent symbol group over a fixed frequency distance and hops the random access preamble signal from at least one of the symbols groups to an adjacent symbol group over a pseudo random frequency distance. Each symbol group comprises one or more symbols. The user equipment is also configured to transmit the random access preamble signal.
