Aspects of the present disclosure provide various wireless communication numerology designs that can maintain symbol boundary alignment while multiplexing different numerologies in wireless communication. The symbols may be scaled for different tone or subcarrier spacings while maintaining the symbol boundary alignment between different numerologies. Maintaining the symbol-boundary alignment between different numerologies enables symbol-level numerology multiplexing. The disclosed numerology designs enable low latency communication and improved interference management, and provide non-ambiguous symbol boundary timing reference for multiplexing different numerologies.

Embodiments of the disclosure provide a method and device for indicating numerology. The method comprises: determining numerology information of a carrier, the numerology information indicating numerologies of one or more basic units for the carrier; and transmitting the numerology information to a terminal device to enable reception based on the numerology information.

The invention relates to a carrier grouping method and device. The method includes the following steps that: a network device classifies a plurality of carriers configured for a terminal as at least one first type carrier group, so that the network device loads control information corresponding to a first carrier on a second carrier and sends the second carrier to the terminal, wherein the first carrier and the second carrier belong to the same first type carrier group; when a plurality of carriers in at least two first type carrier groups are scheduled, the terminal aggregates converges feedback information corresponding to the plurality of carriers on one carrier and feeds back the carrier to the network device; and the network device sends first grouping configuration information to theterminal, wherein the first grouping configuration information is used to indicate the grouping result of the at least one first type carrier group. With the above method adopted, the carrier aggregation scheduling of the network device under different numerology carrier aggregation can be simplified on the basis of the decoupling of a cross-carrier feedback division carrier group and a cross-carrier scheduling division-based carrier group.

A user equipment (UE) receives first configuration information for one or more numerology sets, each numerology set including one or more numerologies. The UE receives second configuration information for one or more logical channels, each logical channel mapped to one or more numerologies. The UE receives a first uplink (UL) grant for new transmission, the first UL grant including information indicating a numerology set associated with the first UL grant. The UE generates a MAC PDU. The UE performs a new transmission of the MAC PDU using the first UL grant. The MAC PDU contains data from a logical channel of which every numerology belongs to the numerology set.

Block spreading generating partial orthogality is applied for the uplink control channel for E-UTRA. For instance, a problem of maximizing the multiplexing capacity leads to numerology causing odd-length sequences which do not have the favorable property of even-length sequences (partial orthogonality). The consequence of this is poor performance in cases of high Doppler effects. Maximal multiplexing capacity is taught without loss of performance at high Doppler by modifying an earlier scheduling request (SR) scheme. The earlier SR multiplexing scheme has a number of parallel SR resources per slot equal to 12*7=84. In one example, the spreading factor of block spreading is changed to an even number, e.g., from 7 to 6. This enables usage of the partial orthogonality properties of CAZAC sequences and as a result inter-code interference in the case of high Doppler is reduced. Other ways to generate partial orthogonality are shown with similar results.

The present application discloses a resource allocation method, the method may include: for multiple resources associated with different parameter sets numerology, transmitting the data of the LCH on the resources matched by the LCH, wherein the LCH is configured with at least one attribute, The attribute is related to the numerology, and the resource matched by the LCH is the resource that least satisfies the attribute requirement of the LCH among the multiple resources. The above-mentioned solution can support multi-service transmission while comprehensively considering the attribute requirements (such as delay requirements) of LCHs used to carry various services, avoiding "oversatisfaction" for a certain (some) LCHs, and satisfying all LCHs as much as possible attribute requirements.
