Abstract

A transceiver for a wireless communication system is described. The wireless communication system provides resources to be allocated for respective transmissions in the wireless communication system. The resources include one or more bandwidth parts, BWPs, a BWP having a certain numerology and including a plurality of subcarriers in the frequency domain. At least one of the BWPs includes a plurality of resource sets for a sidelink communication, the plurality of resource sets including at least a first resource set and a second resource set, the first resource set being associated with a first criterium, the second resource set being associated with a second criterium, and the first criterium and the second criterium being different. The transceiver is configured to use resources from one or more of the plurality of resource sets within the one BWP for a communication.

First claim

1 . A transceiver for a wireless communication system, the wireless communication system providing resources to be allocated for respective transmissions in the wireless communication system, wherein
the resources include one or more bandwidth parts, BWPs, a BWP having a certain numerology and including a plurality of subcarriers in the frequency domain, at least one of the BWPs includes a plurality of resource sets for a sidelink communication, the plurality of resource sets including at least a first resource set and a second resource set, the first resource set being associated with a first criterium, the second resource set being associated with a second criterium, and the first criterium and the second criterium being different, and the transceiver is configured to use resources from one or more of the plurality of resource sets within the one BWP for a communication.

2 . The transceiver of claim 1 , wherein the first and second criteria comprise one or more of the following:
a communication type, e.g. unicast, groupcast/multicast or broadcast, a traffic type, e.g. aperiodic/one shot or periodic/SPS, an operation mode, e.g. Mode 1 (in coverage) or Mode 2 (out of coverage), a QoS requirement, e.g. priority, latency, reliability or communication range, a zonal location, e.g. zone ID, a geographical grid, routes or special points of interests, like crossings).

3 . The transceiver of claim 1 , wherein a plurality of different resource sets are defined within the one BWP for different communication types having associated therewith different reliability and latency requirements, the communication types including one or more of a broadcast, a groupcast, a multicast or a unicast communication.

4 . The transceiver claim 1 , wherein a first resource set is defined within the one BWP for periodic traffic, like a SPS-communication, and a second resource set is defined within the one BWP for aperiodic traffic, like one-shot transmissions.

5 . The transceiver claim 1 , wherein a first resource set is defined within the one BWP for Mode 1 UEs, and a second resource set is defined within the one BWP for Mode 2 UEs.

6 . The transceiver claim 1 , wherein
a first resource set is defined within the one BWP for a first QoS requirement, a second resource set is defined within the one BWP for a second QOS requirement, and a third resource set is defined within the one BWP for a third QoS requirement, the first QoS requirement being higher than the second QoS requirement and the second QoS requirement being higher than the first QoS requirement, wherein the QoS requirement may include a priority of the transmission, wherein, optionally, a design of one or more of the resource pools may vary according to the QOS requirements, e.g., control and data resources may be in a TDM or FDM fashion, or according to any one of the designs defined below.

7 . The transceiver claim 1 , wherein a plurality of different resource sets are defined within the one BWP for different zones or zonal areas or a geographical grid, routes or special points of interests, like crossings, of the wireless communication system.

8 . The transceiver claim 1 , wherein the resource sets are defined within the one BWP in one or more of the following manners:
continuous over time and contiguous over frequency, continuous over time and non-contiguous over frequency, discontinuous over time and contiguous over frequency, discontinuous over time and non-contiguous over frequency.

9 . The transceiver of claim 8 , wherein in case of a resource set being continuous over time and contiguous over frequency, across time the resources, like time slots or subframes, are continuous and adjacent to each other, and across frequency the resources, like resource blocks, RBs, are contiguous and adjacent to each other, wherein the resource set may span an entire duration of the one BWP or a specific time within the one BWP.

10 . The transceiver of claim 8 , wherein in case of a resource set being continuous over time and non-contiguous over frequency, across time the resources, like time slots or subframes, are continuous and adjacent to each other, and across frequency at least some of the resources, like resource blocks, RBs, are non-contiguous and are not adjacent to each other, wherein the resource set may span an entire duration of the one BWP or a specific time within the one BWP.

11 . The transceiver of claim 8 , wherein in case of a resource set being discontinuous over time and contiguous over frequency, across time at least some of the resources, like time slots or subframes, are discontinuous and are not adjacent to each, and across frequency the resources, like resource blocks, RBs, are contiguous and adjacent to each other.

12 . The transceiver of claim 8 , wherein in case of a resource set being discontinuous over time and non-contiguous over frequency, across time at least some of the resources, like time slots or subframes, are discontinuous and are not adjacent to each, and across frequency at least some of the resources, like resource blocks, RBs, are non-contiguous and are not adjacent to each other.

13 . The transceiver of claim 1 , wherein some of the resource sets defined within the one BWP partially overlap each other.

14 . The transceiver claim 1 , wherein
the resource sets are defined across time in any one of the following manners: by a bitmap across time, the bitmap indicating resources, like OFDM symbols or time slots or subframes or frames, where the resource set is defined, spanning either a portion or the entire length of the one BWP, by a starting resource, like a time slot or a subframe, and a duration of the resource set, by explicit resources numbers, like time slot or subframe numbers, by puncturing out resources mentioned explicitly or that are part of another set of resources or RP, and by a starting resource, and periodic offsets for subsequent occurrences, and wherein the resource sets are defined across frequency in any one of the following manners: by a bitmap, the bitmap the bitmap indicating resources, like resource blocks, across the one BWP, by a starting resource, like a resource block, and a number of resources for a resource set, by multiple starting resources, like resource blocks, and ending resources, if the resource set is non-contiguous over frequency, by explicit resource indices, like resource block indices, by puncturing out resources mentioned explicitly or that are part of another set of resources or RP, and by a starting resource, and periodic offsets for subsequent occurrences.

15 . The transceiver claim 1 , wherein the wireless communication system includes a plurality zones or zonal areas, and for a given zone there exists a BWP configuration with the plurality of resource sets defined within the BWP, wherein the transceiver is configured to decide the active BWP by a current zone in which the UE resides and operates,
wherein a zone or a zonal area may be, e.g., one or more of the following: a geographical grid, or routes, or special points of interests, like crossings.

16 . The transceiver of claim 15 , wherein the transceiver is configured to identify a zone associated with the transceiver using a zone ID of a zone, e.g., using a modulo operation, and to identify a resource set from which the resources for the SL communication are scheduled using the zone ID, the number of zones and the number of options for each of the first and second criteria.

17 . The transceiver of claim 15 , wherein a resource set is identified by a NR zone
