Abstract

Official abstract text for this publication.

Methods and apparatus in a fifth-generation wireless communications, including an example method, in a wireless device, that includes receiving a downlink signal comprising an uplink access configuration index, using the uplink access configuration index to identify an uplink access configuration from among a predetermined plurality of uplink access configurations, and transmitting to the wireless communications network according to the identified uplink access configuration. The example method further includes, in the same wireless device, receiving, in a first subframe, a first Orthogonal Frequency-Division Multiplexing (OFDM) transmission formatted according to a first numerology and receiving, in a second subframe, a second OFDM transmission formatted according to a second numerology, the second numerology differing from the first numerology. Variants of this method, corresponding apparatuses, and corresponding network-side methods and apparatuses are also disclosed.

First claim

Opening claim text (preview).

What is claimed is: 1. A method, in a user equipment (UE), for operating in a wireless communications network, the method comprising: receiving a downlink signal comprising an uplink access configuration index, using the uplink access configuration index to identify an uplink access configuration from among a predetermined plurality of uplink access configurations, and transmitting to the wireless communications network according to the identified uplink access configuration; and receiving, in a first downlink subframe, a first Orthogonal Frequency-Division Multiplexing (OFDM) transmission formatted according to a first numerology and receiving, in a second downlink subframe, a second OFDM transmission formatted according to a second numerology, wherein the first numerology has a first subcarrier spacing and the second numerology has a second subcarrier spacing, the first subcarrier spacing differing from the second subcarrier spacing; wherein the method further comprises: receiving broadcasted system access information and using the received system access information for accessing the wireless communications network. 2. The method of claim 1 , further comprising operating in a connected mode for one or more first intervals and operating in a dormant mode for one or more second intervals, wherein said first and second OFDM transmissions are performed in the connected mode, and wherein said operating in the dormant mode comprises: monitoring signals carrying tracking area identifiers; comparing tracking area identifiers received during said monitoring with a tracking area identifier list; and notifying the wireless communication network in response to determining that a received tracking area identifier is not on said list but otherwise refraining from notifying the wireless communication network in response to receiving changing tracking area identifiers. 3. The method of claim 1 , wherein said first and second downlink subframes are received on the same carrier frequency. 4. The method of claim 1 , wherein said first OFDM transmission has a numerology according to specifications for Long-Term Evolution (LTE). 5. The method of claim 1 , wherein said first and second numerologies comprise subframes of first and second subframe lengths, respectively, the first subframe length differing from the second subframe length. 6. The method of claim 1 , wherein subframes of said first and second numerologies comprise first and second predetermined numbers of OFDM symbols, respectively. 7. The method of claim 1 , wherein at least one of said first and second numerologies comprises subframes having a length of 250 microseconds or less. 8. The method of claim 1 , wherein the method further comprises: requesting additional system information from the wireless communications network; and receiving additional system information from the wireless communications network, in response to said requesting. 9. The method of claim 1 , wherein the method further comprises receiving additional system information from the wireless communications network, in a dedicated transmission. 10. The method of claim 1 , wherein said first OFDM transmission is frequency-multiplexed with and at least partly overlapping in time with said second OFDM transmission. 11. The method of claim 1 , wherein the method further comprises: receiving, in a first-in-time OFDM symbol of said first or second downlink subframe, downlink control signalling in a first set of subcarriers of said first-in-time OFDM symbol and dedicated user data in a second set of subcarriers of said first-in-time OFDM symbol. 12. The method of claim 1 , wherein the method further comprises: transmitting acknowledgement (ACK) or negative acknowledgement (NACK) data in response to said first OFDM transmission in said first downlink subframe, in a last OFDM symbol of an uplink subframe interval at least partially overlapping said first downlink subframe. 13. The method of claim 1 , wherein said first downlink subframe comprises one or more reference symbols in the first-in-time OFDM symbol of said first downlink subframe, and wherein the method comprises beginning decoding of said first OFDM transmission in said first downlink subframe before a duration of said first downlink subframe has ended, using a channel estimate based on said one or more reference symbols. 14. The method of claim 1 , further comprising receiving information defining said plurality of uplink access configurations, on a first carrier, wherein the downlink signal comprising said uplink access configuration index is received on a second carrier, differing from said first carrier. 15. The method of claim 1 , further comprising receiving a third OFDM transmission formatted according to said first numerology, said third OFDM transmission occupying a transmission time interval (TTI) having a length equal to a plurality of subframes according to said first numerology. 16. The method of claim 1 , wherein at least one of said first and second OFDM transmissions is a Discrete Fourier Transform-Spread OFDM (DFTS-OFDM) transmission. 17. The method of claim 1 , further comprising receiving and processing first Layer 2 data on a first physical data channel and receiving and processing second Layer 2 data on a second physical data channel, wherein said receiving and processing of the first Layer 2 data comprises the use of soft HARQ combining and wherein said receiving and processing of the second Layer 2 data comprises no soft HARQ combining. 18. The method of claim 17 , further comprising using a common set of demodulation reference signals for receiving both the first and second Layer 2 data. 19. The method of claim 18 , wherein said common set of demodulation reference signals is a user-specific set of demodulation reference signals. 20. The method of claim 18 , further comprising receiving a physical control channel using a set of demodulation reference signals that differs from said common set of demodulation reference signals. 21. The method of claim 1 , wherein the method further comprises processing data from said first OFDM transmission using a first Medium Access Control (MAC) protocol layer and processing data from said second OFDM transmission using a second MAC protocol layer, said first MAC protocol layer differing from said second MAC protocol layer, and wherein the method further comprises processing messages received from each of said first and second MAC protocol layers using a single, common Radio Resource Control (RRC) protocol layer. 22. The method of claim 1 , wherein the method further comprises processing data from said first OFDM transmission using a first Medium Access Control (MAC) protocol layer and processing data from said second OFDM transmission using a second MAC protocol layer, said first MAC protocol layer differing from said second MAC protocol layer, wherein the method further comprises processing messages received via said first MAC protocol layer using a first Radio Resource Control (RRC) protocol layer and processing messages received via said second MAC protocol layer using a second RRC protocol layer, said first RRC protocol layer differing from said second RRC protocol layer, and wherein at least a first one of said first and second RRC protocol layers is configured to pass selected RRC messages to the other one of said first and second RRC protocol layers, the selected RRC messages being RRC messages received and processed by the first one of sai
